The present invention relates to a solar energy conversion device, in particular to an apparatus or device which is ordered to monitor (track) the sun's course and to concentrate the sun 's energy on a surface or surface surface.
There are many examples of energy conversion devices of the type noted above but most suffer from the defect of inaccurate monitoring of the sun's course which has a negative effect on the performance of the function.
The general object of the invention is to provide a concentrating device or which is relatively simple in construction and which monitors the course of the sun accurately and safely.
According to the present invention there is provided a solar energy conversion device or which comprises a means for concentrating solar energy on at least one surface, a means for provoking the means of concentration which the sun may monitor. Said monitoring device comprising radiation sensitive elements which operate in the presence of a differential thermal expansion thereof to produce monitoring control signals and an electric motor driven by the said moving motor assembly.
Preferably said radiation sensitive elements have a predetermined reaction time during which they are subjected to radiation before being produced; awkwardness for the awkwardness of the movement of the said movement when / '

Concentrate concentrates solar energy on the said surface, said reaction medium having a reaction time which is shorter than that of said sensitive elements.
Further preferably, the radiation sensitive elements comprise thermally distillate metal strips which operate in a manner analogous to those contained in the apparatus or disclosed herein. 35; 7s / 7s, filed April, April 1978. The means of inhibition may include at least one photocell.
* The device defined above has many advantages. "A special advantage is the fact that the monitoring movements are stimulated by concentrated solar energy falling on the expanding bands. This almost completely removes the possibility of the monitoring system being exposed to random light which has been found to be a systemic problem which relies solely on photoelectric cells for monitoring signals. Furthermore, the device of the invention uses a photocell to inhibit the movement of the cohesive means and it has the particular advantage that it can be made to have a very short reaction time so that the cohesive material stops the sun. Furthermore, the photocell or cells may be adapted to reflect only the collected solar energy from the coagulation medium itself, thereby further eliminating the functionality of the device by accident.

The tube 4 is preferably oriented in the direction of Sorra ^ albeit at a predetermined altitude angle depending on the latitude of the position where the device is to be used. A means of monitoring the course of the sun is provided to compel the boat 2 to follow the sunrise from the east to the core during the day.
* The vessel is mounted in an outer housing 6 made of sheet metal and having a pair of short side walls 8. CN frame members extend from the side walls 8 to a longitudinal support bar 12 in spaced and spaced between the port areas which are covered by glazing 14 vessels also closed by glazing S6 having a shape.

In general, the apparatus of the invention comprises first heat sensitive elements to stimulate the rotation of the boiler 54 in the appropriate direction and a second element or elements which react to light and / or heat of the second element or time elements; reactors and operators to control the rotation of the boiler 54 when the vessel is sharply aligned with the sun. Vessel 2 may comprise a single parabolic aelastic epitaph having a focal line or which is concentric after the heat transfer tube 4 but nevertheless parallel focal lines 46 and 42 which preferably lie on opposite sides of the tube 4; as schematically illustrated in Figure I5; a general idea of dual focal lines is disclosed in Australian Patent Application no. 55 · ± 76/73. The thermal reaction elements comprise the first and second metal strips 44 and 45 which are parallel to each other and as shown in Figure 5 lie at the central longitudinal plane of the crack but as shown in Figure 2 are positioned against each other. of the axis 52. Tapes 44 and 46 comprise preferably blackened mild steel and are designed to pass through a passage through the Zai vessel.

belts 44 and 4S are connected to a rotating plate 48, of the plate 43 rotatable according to the differential thermal expansion of the strips 44 and 46 caused by poor alignment of the vessel after the sun. The plate 48 passes through a hole 51 in a support plate 52 or which is connected to the support rod 12 by means of a spring of tension 5; as shown in Figure 6, the plate 48 will rotate about an axis 58 differentially. expansion of strips 44 and 46, the direction of rotation depending on which of strips 44 or 46 has been irradiated by the vessel. Fluctuations in ambient temperature will cause the strips 44 and 46 to expand or contract at the same time, and such movements are covered by the tension spring 54. As explained in the preceding statement, it is necessary to protect the strips 44 and 46 above the shaft and therefore the upper parts of the strips 44 and 46, plates 48 and 52 are placed in a reflective housing 57 and tape as shown in Figure 4. '6 a guard is formed from the strips 61 to hold it in place between the strips.
The free ends of the plate 4-8 are connected to a yoke 58 from which extends a drive rod 66 or which thus also rotates about the axis 58. The rod 66 passes through a hole 52 in the lower wall of the beam 12 and extends through the tube Ϊ2, of the upright 16, into a housing 64 located above the gear box 58. The free end of the control rod 56 is rotatably connected to one end of a lever 6 which rotates about 1 mm.
<img file="GR73867B_D0013.tif" />
this is rotating around a pair and? 2, it is said that 5
ICs 44 and 46 of the upper end of the lever 66 lie in a neutral position between the 7C and 72 microswitches and actuate any of the switches. However, when there is a differential expansion of the strips 44 and 46 when a sufficient temperature rise has occurred in one or the other of the strips 4-4 or 45 the lever 46 will engage one or the other of the 7th or 72 microswitches, depending on which of the film has a rise in temperature.
The envelope 54 also contains a pair of microswitches 74 and 76 which close when an overheating is felt in the heat transfer tube 4. According to the device shown in Figure 5, the microswitches 74 and? 5 are arranged to be actuated when struck by a rotating plate 78 ". normally hold the plate 76 away from the microswitches 74 and 75. Hyperdermalities in the heat transfer tube 4 are induced by thermal expansion in the same tube and in this favor the end of the tube is fixed on the axis 30 but the other end is freely expandable and expands. which when the tube 4 is expanded by a predetermined amount will engage in one end of a drive lever 86 which rotates in the ram, .thon 12. The other end of the lever 85 passes through the tube, the upright 13 and into the housing 54 and lies adjacent to the spring 80. The collar 84 therefore causes the lever 85 to rotate and thus come into contact with the spring 80 causing the plate to come into place directly into the engagement with the other side of the micro-switches; δέσιυ ταύτην ε? ιος εαυ είς τήυ αρχικήν θέσιν διά της χειρός διά τοΰ ^ ειριξσμου μοχλοΰ έπαναφορά 88

II Differential expansion of the straps will thus cause the vessel to rotate. According to the invention when the boat is properly aligned after the sun the photoelectric cells are activated and cause the engine to stop rotating the boat. The cells have a very short reaction time so that it ensures that the vessel stops precisely when it reaches the correct alignment position.
In the embodiment shown in Figures I and 13 there are four photoelectric cells arranged in pairs 90, 92 and 94, 95 on opposite sides of the barren 32. The first pair 9o, 92 is supported by a support plate 98 or below the bar 12 and the second pair 94, 95 rests on a support plate 100 ° or which extends downwards from the bar 12 but is arranged spaced substantially from the plate 98. Now looking at the circuit diagram of Figure II, it will be seen that cells 92 and 94 are connected in parallel to an activation coil 102 of a relay 104. Cells 9u and 95 are connected in parallel to an activation coil of an electron. The arrangement is such that when either cell 92 or 94 is irradiated under concentrated sunlight, the ISO contact arm will move to its open circuit position and similarly if each of the cells is close to 9 or more. κινθή είς τής Θέσιν αυοι?: τοΰ κυκλώματος αύτοΰ. virus circuit will function therewith only after a single pair of cells say 9th and 92nd but it is desirable to include in an indirectly identical pair 94 and 95 so that if cells 95 and 9 are to be shaded, strain Io;
Similarly, the presence or absence of cells on opposite sides of axis 32 further reduces the likelihood that all cells will be found at the same time in shaded animals. Cells 90, 92, 94, and 96 sec produce sufficient current to activate the electromagnets ± 04 and 108 except when exposed to concentrated sunlight and thus are therefore not necessarily necessary or unavoidable.

The complete circuit of Figure II will be described now. The box 34 is connected to the contact arm of the hyperthermic microswitches; 4 and 76; The terminals I ± 8 and 120 are directly involved and the terminals are connected respectively to terminals 122 and ± 24. The connecting arms ± 10 and 10 ± 2 of the Coectrons 104 and ± 08 caudally engage terminals 122 and ± 24, respectively. The other end arms of the i ± φ and 1x2 are connected to a positive line 126 or which is connected to a positive voltage source by means of a sliding ring 120. The microswitches 7 ^ and 72 include terminals ± 30 and 132, respectively, which are connected to a negative IP4 line or which is connected to the negative terminal of the supply line via a sliding ring ± 36. The microswitches 74 and 76 include a terminal ± 30 'and ω 4h, respectively, of the terminal ± 33 of the connected 4, and of the non-terminal ± 4x of the terminal ± connected to the positive line 123 via a sliding ring.
<img file="GR73867B_D0015.tif" />
- 15 In the position of the circuit as shown the motor 34 is not activated because both of its wires are connected through the various microswitches and relays to the positive line 126. In this position, lever 66 (see Figure 5) does not engage any of the 7C and 72 microswitches of the 2-axis vessel correctly aligned with the sun, when the sun is moving relative to the surface of the vessel or the rock. will cause one or the other of the contact arms of switches 7o and 72 to move to lock terminals 130 or 132. In this case the circuit to the motor 34 is complete because either of terminals 130 or ± 32 will be connected to the negative line ± 34.
This will cause the engine 54 to rotate in the direction or which is suitable for aligning the boat after sunlight, provided that the contact arm of the switch ± 32 is driven to engage the drive 34 and will continue until the vessel reaches its correct alignment after the sun in which case cells 90, 92, 94, 9 will be irradiated after concentrated sunlight. The irradiation of cells 90 and 96 will be ineffective because the relay ± 30 has been effectively removed from the circuit by the microswitch 72. * In these cases, currents generated in one or both of the cells 92; 94 will cause the contact arm ±± 0 of the relay arm ± 04 to disconnect from terminal 122 and thus shut off the circuit 34 to the motor. to suspend the vessel in a position which is correctly aligned with the sun, i.e. in which the focal lengths 40 and 42 lie on the surface of the tube. 4. Operation occurs when the lever is in front.

contact of the microswitch 7th to come into contact after terminal 130 except that the direction of rotation of the motor 34 is inverted.
When the device is in, it is in perfect alignment with the sun and the device is monitoring the direction of the sun; In this mode the switches 76 or 72 may continuously engage their contact arm with terminals 130 or ± 32 of the motor circuit interrupted by the 90 '96 or 92 'cells; 94 operating the relays IC8 or ± 04. Thus in this mode of operation the reaction time is short, i.e. the reaction times of the cells. The device has been tested and in this mode the motor typically moves for 0.25 to 0.5 seconds following a period of said minute during which it does not move.
Figure 5 shows more accurately the position of the 9V cells, 92, 94 and 96 relative to the tube. of the surface of the tube 4. The diagram shows the extreme radii 144 and 146 of the inner and inner edges of the right parabolic portion of the vessel as well as the extreme radii ± 43 and the radius of the left parabolic portion.
It will be noted that the 9th and 92nd cells are positioned so that their adjacent inner edges collide

0) 0 on the adjacent inner edges of the cells rather than on the outermost edges of the cells which were incorrectly introduced into the sun's follow-up. To illustrate this, assume that the vessel is out of alignment after the sun in which case the focal line 142 will be placed, for example, at the point marked 152. After such misalignment the lever 66- will cause the contact switch of the microswitch 70 to engage the terminal 150 and thus start the rotation of the motor. 42. During this movement the focal line will strike the inner edge of the cell 92 but this is inconsistent because the relay 04 is effectively isolated by the microswitch 70; the motor circuit will stop and thus the rotation will stop. In the corresponding mode it works when the misalignment is in the opposite sense.
The voltage source which is connected to the sliding rings I2a and Ips is comprised to include an excitation voltage from a mains supply of alternating current or an electrically conductive circuit consisting thereof.

16 motor b4 and rotation will continue until the motor circuit stops via a cam switch cooperating with the sliding ring 142. Figures 7 and 3 illustrate a preferred configuration of the sliding ring 14, 128. The sliding rings are mounted on collars ± 54 formed of insulating material. An insulating collar virus 154 which cooperates with the sling ring 142 is formed by a protruding center portion 150 which, when properly rotated thereafter, will engage the ring and the corrugated conduit 158 this will cut off the circuit to the engine 34 when the boat is facing downwards so that it can not receive any further sunlight; The insulating rings ± ρ4 are mounted on an integral part of a hollow cylindrical body 152 which is attached to the crankshaft> 6 and is therefore rotatable thereto. The sliding rings and carbon bodies -3 5-3 are placed in a protective housing 164 which you attach to the end support 24.
Figure 7 also shows a form of the support for the tube 4 on the axis 23. In this arrangement the support comprises a pair of semi-circular ceramic members 165 formed by corresponding shapes having a corresponding shape: the tube 4.

70, 72, 74 and 76 operate as in the circuit of Scheme II except that the terminals IJC and IJ2 are connected to the negative line IJ4 via a relay 172, the coil 174 of which is actuated by cell 176 '; Further 118 and 120 are directly connected to Positive Line 126. It will be noted that the function of the relay 172 isolates terminals 130, 132 from the negative line 1J4 thus disconnecting the circuit to the motor 54 except when the overload relays are activated.
In this arrangement as soon as cell 170 produces sufficient current to operate relay 172, the motor will stop. It is therefore desirable to have a device for regulating the radiation from the reflector so that the monitoring of the sun's course is more accurate, as Figure 14 illustrates an untrained technique so that only a narrow band 130 of radiation can reach the cell 170.

Plate 98 functions as Heat Loss for cells 90 and 92 and the preferred method of support is shown schematically in Figure CN. In this arrangement the cell slice is placed on a conductive plate 9- or which engages a well insulating layer 136 which is then supported on a load-bearing plate 186.

The preferred embodiment for the boat will now be described with reference to Figures Ib to 18. The Fig. Ib shows the housing as having a generally parabolic shape after being turned upwards. of the housing. The beams 194 provide central support for a number of ribs 195 where; they are connected at their outer ends to the side walls 8. I9S ribs each have a precisely cut concave acne 193 or which has a central planar portion of about 7 "L - - z.

19 'The hole 50 through which the strips 44 and 46 pass is formed by a pair of shorter strips on either side of the gap 5.<sup>ϋ</sup>, as shown in Figure Figure.
Figure 17 illustrates the preferred technique of precisely holding the sheets 202 on the parabolic edges of 198 ribs. The sheet 202 is formed having a step portion which includes an upward leg 204 and a fastening portion of the 2CS ear. The outer edge of the ear portion is inserted into a reinforcing member 208 which is generally U-shaped and engages after the outer edge 210 of the ear portion 206. The booster strain 208 extends the width of the leaf 202. The strain 208 is provided by a pair of aligned holes 212 through which it passes through one end of the pressure springs 214<sup>;</sup>. It is provided after a tolerance of 216 so that the springs 214 do not engage the tab portion 205. The other end of the spring 214 rests on the side walls 8 of the housing and the arrangement is such that the springs 214 .in the direction of the pair 218 ie towards the center of the vessel and down to the ribs 196. the reinforcing members 208 ensure that the result of pushing the joints

Unwanted distortion of the material in the sheets at the edges of the boat. It will be noted that a gap 228 is left between the upwardly turned leg 2θ4 of the plate and the upwardly turned tab 222 of the beam 220 so as to cover a difference in thermal expansion between the ribs 196 on the one hand and on the other end2. of another.
Figure 18 illustrates a suitable bearing for the reflective plates in the hole b. In this case the ribs 196 are connected to a pair of internal 2p0 support beams mounted on either side of the 5 ΰ gap;
The beams 250 have a downward-pointing lug which has a slot to accommodate the ribs ± 96 and the ribs themselves are formed by incisions 252 to receive the beams 250. The beams 250 are supplied with is supported as shown by a portion of the upturned leg 256 of the plate 202. The boat of the previous construction has been found to be capable of relatively easy construction and nevertheless provides a very good focus or which is necessary for the efficient operation of the device. Prototypes of the previous construction have been constructed and found of the sun. * Monitoring can be considered as three distinct modes of operation, - in the first way there is a clear misalignment between the boat and the sun until THEN I, it happens at dawn. As disclosed in the Australian Patent Sewage Fluid No. 55 · 2? - / 76 The shortest ends of the ribbons 44: tai 43 will make the initial position of the vessel towards the sun;

- '•• y of the vessel itself will focus on one or the other of films 44 and 46 and this will cause a larger difference in hot wine between the strips, of the vessel being intercepted by the cells when it is correctly aligned with the sun. Finally, the third way is the normal mode of continuous monitoring in which case the tape or which is placed in the most substantial direction will have more or less continuously concentrated solar radiation on one side of the screen. Monitoring movements in this case are subject only to the concentration of light by themselves or more of the photocells. In the third mode of operation the reaction time depends only on that of the cells, in other words, it is very fast and therefore very accurate monitoring is achieved.
When the sun is moving backwards towards a cloud, the device will enter the second mode of operation and has either diffuse thermal energy or which is received under the ska, .. is sufficient to operate tapes 44 and 43 so that monitoring The path of the sun is still strong through clouds of moderate density. This is very advantageous because when the sun ceases to rise from the clouds, the boats can very quickly get in the right alignment and start tracking against the third mode of operation.
Figure 19 illustrates test results of the monitoring device of the invention. * The Iro curve graphically shows the input expressed in square meters as a function of time, and it will be noted that the output is much larger than that generated by the absorber-type absorber-type absorber. of the outputs of the two single I4C curves etc. 142.
