Wind-driven electric plant

The invention relates to wind motors that can be used as force aggregates for actuating, for example, electric generators.

It is known the construction of the wind power plant consisting of conductive shaft, blades, reducer, traction cables [1].

The disadvantage of this installation is the inefficient use of the wind for rotating the drive shaft.

The closest technical solution to the present invention is the construction of the wind energy installation that includes a support, driver shaft, о pair of blades that form horizontally the letter S which has the center of symmetry located on the rotational axis of the drive shaft [2].

The disadvantage of this technical solution lies in the fact that in the rotor during the rotating process there is a dynamic uniformity (ie an imbalance), due to the unevenness of the air flow that hits the blades, secondly, the air flow in the vicinity of the installation cannot be used. .

The problem solved by the invention consists in removing the unevenness of the rotation of the blades and in the more productive use of the air flow in the vicinity of the installation.

The wind energy installation according to the invention removes the disadvantages mentioned above by confining a vertical rotating shaft with о pair of blades that form horizontally the letter S, a reducer and an electric generator, new being that around the blades, on the top and the lower one, two obliques with obese hollows are rigidly fixed, the cross section of which is executed in the form of a drop with the tip oriented towards the outside of the wheel, at the same time, in the obese cavity, a liquid resistant to frost is introduced, partially occupying the volume of the cavity.

The installation is also characterized by the fact that at the top and the bottom the vertical rotating shaft is articulated, by means of rods with a pillar, as well as articulated, there is also a deflector of the airflow equipped with a drive shaft and with a deflector swivel fastener.

The result is to ensure a more even rotation of the vertical shaft, independent of the wind gusts, as well as a more efficient use of wind energy.

The invention is explained by the drawings in FIG. 1 ... 4 which represents:

FIG. 1, the generated view of the wind energy installation;

FIG. 2, the diagram of the position (top view) of the deflector with respect to the rotational axis of the S-shaped blades;

FIG. 3, diagram of the location of the wind energy installation near the highway;

FIG. 4, the cross-section of the wheel with the hollow cavity intended to automatically remove the imbalance. The wind energy installation 1 confines a driving shaft 2 for the transmission of the torque and the horizontal fixing of the hollow wheels 3 and 3¹ with liquid 4, for example, antifreeze for automatic removal of the imbalance, blades in S 5 and 6 fixed by the conductor shaft 2, pillar 7 with horizontal rods 8 and 9 for the vertical fixation of the driving shaft 2, deflector 10, for directing the flow direction. air 11 to the blades 5 and 6, the drive shaft 12 provided with a fastener 13 for changing the position of the baffle 10 relative to the longitudinal axis of the shaft, the edges 14 for decreasing the air resistance, articles 15 for fixing the baffle 10 by the pillar 7.

The wind power plant is installed near the freeway part 16 of the highway. It also confines a reducer 17 for multiplying the rotations of the blades, an electric generator 18, spife 19 for the rigid attachment of the obese 20 of the driving shaft 2, the obada being hollow, and in cross section having a drop shape to reduce the air resistance at increased wind speeds. . The convex surface 21 of the blades is made with a wind damping layer 22 provided, for example, from polyethylene having a thickness of 1.5-10 mm, the cells of 12 x 12 mm, the pitch of the cells of 20-25 mm. The reinforced concrete foundation 23 is intended for the rigid fixing of the wind energy installation on the base 24 near the highway. The pallets have a concave surface 25. The bearing 26 with bearings is executed for fixing the drive shaft vertically, and the sleeve 27 for connecting it to the gearbox.

Wind power installation can operate in two regimes.

The first operating mode is performed in the absence of wind. When moving vehicles on the motorway side of the highway, in relation to the wind energy installation 1, an air flow 11 is created. The power of the air flow 11 depends on the frequency of movement of the vehicles, the dimensions of the vehicles and the speed of their movement. The air flow 11 spreads to the wind energy installation 1 and, reaching the concave surface 25 of the blades 5 and 6, engages them in a rotational motion. At the same time, the air flow 11 is deflected towards the concave surface 25 and by the deflector 10, thus leading to an increase in the rotational speed of the blades 5 and 6. From this moment the blades 5 and 6 with the wheels 3 and 3 are actuated.¹, the drive shaft 2, the gearbox 17 and the electric generator 18. The electricity generated can be transmitted, for example, to a block of photoelectric cells and propagated to electric projectors, which will illuminate the carriageway part 16 of the motorway.

Upper wheel 3 and lower wheel 3¹, in common with the drive shaft 2, the blades 5 and 6 with the wind damping layer 22 form a rotating cylinder of a certain mass that accumulates kinetic energy, which is used when operating the electric generator 18, partially reducing the unevenness of the rotation.

In the case of wind gusts, pallets 5 and 6 rotate ununifbrm. In this case, the so-called "balancing system" is automatically operated. The fluid 4 in the obese cavity 20 begins to resist resistance by rubbing the obese edges and reducing the imbalance in the rotating cylinder, ie the unevenness of the rotating shaft of the drive shaft 1. Thus the imbalance will be automatically removed, thus increasing the efficiency of the wind energy installation.

The second mode of operation of the installation is called combined mode and is performed when, apart from the air flow 11 created by the vehicles moving on the motorway, from a slightly blowing direction and the wind, contributing to the increase of the rotational moment applied to the shaft. conductor 1. In this case, towards the concave surface 25 of pallets 5 and 6, the bundle of two air flows 11 already acts, which leads to an increase in the efficiency of the installation.

Execution of pallets 5 and 6, according to the drawings, fixing them on the shelves 3 and 3¹ of the driving shaft 2 leads to the rotation of the latter in a single direction, regardless of the direction and speed of the air flow 11.

Depending on the predominant type of car transport that is traveling on the road side, the size of the angle of placement of the baffle 10 is adjusted in relation to the longitudinal axis of rotation of the driving shaft 2.

Thus the present invention ensures the increase of the efficiency of the installation and the use of the air flow created by the moving vehicles.
