Ultrasonic wave type remote leakage monitoring apparatus

[Detailed Description of the Invention]

[Field of the Invention] This Brother starts the equipment maintenance art and operation surveillance art of a plant, and is related with the ultrasonic type remote disclosure monitoring instrument which detects disclosure of various equipment, apparatus, the high-pressure gas from piping, a fluid, steam, etc. [Description of the Prior Art] Conventionally, there was an ultrasonic-type leak detection device as this kind of a device. This leak detection device carries out Accompanied′ ultrasonic wave Ringing all detection at disclosure of fluid, such as equipment, apparatus, high-pressure gas from piping, a fluid, and steam, has the feature that that disclosure can be See brother(ed) in the stage of a very very small disclosure, and when it needs strict Detection, it is often used. Using the leak detection device of the conventional super-Him type mentioned above, Drawing 1 shows the state where disclosure in a plant is actually detected, and sets it to a figure, (1) piping [ Rolling and / this ] (1) K Receives for piping used as a lateral strain object, and the round check member (3) is carrying out the lateral strain with the ultrasonic leak detection device (2). That is, it is checked whether disclosure has produced the round check member (3) by patrolling the inside of a plant with a portable type ultrasonic wave leak detection device (2), and bringing Centen of Detecting device correction (2) part (2a) close to a check part at the part which requires check. Since an ultrasonic leak detection device (2) detects disclosure using super-A wave of high frequency, Attenuation in the air is large instead of the ability to perform detection of a very small disclosure, and 7 Sensa parts (2a) have Need to get closer of enough in a check part, and it must make it have to make the place which disclosure is likely to produce have to scan at a valley check ' part. Thus, since man (3) needed to carry the Kikuchi detecting device (2) of the conventional super-sound temporary type and it needed to patrol the inside of a plant, there was a fault that danger of radioactive exposure could not use Ahupsilon and a human being (3) in the environment where it cannot enter easily, like [ in the container of a nuclear power plant ], for example. [Summary of the Invention] Three brothers BA removes the fault in the conventional thing mentioned above, an ultrasonic sensor is attached at the tip of many articulated arms, this is carried in a remote moving system, and the inside of a plant is patrolled and supervised, It aims at providing the ultrasonic type remote disclosure monitoring instrument which enabled it to detect disclosure remotely. [Example] Hereinafter, 0 figure 2 which gives Yo Si explanation shows the example of the present invention to the example which shows the present invention to a drawing, The remote moving system (4) which was provided with car @ (4a) and whose run was enabled is m Carried out, and it is a mortar in this remote moving system (4)! The many articulated arms (6) to which the ultrasonic sensor (5) by the side of the ultrasonic sensor part (2a) explained in 1 figure and 1 Boss was attached at the tip are protrusion Be angry. move-♂ These many articulated arms (6) are [ predetermined one ] for closing and carrying out the footstep of the ultrasonic sensor (5) in a check place up to 1 themselves about an ultrasonic sensor (5), As these many articulated arms (6), the arm mechanism of Crescent month 40 common bot is adoption, and it is last power; 811. As it Ho(ed), as for ultrasonic waves 1i accompanying disclosure, attenuation in the air is large and Motion is check +;lX(being [ 'Jf and v This Jd part Keeping close ], Up 7 This Brandt CT) j* V* and 10Some writingsJ about an ultrasonic sensor (5). Power [ -- piping has 9''f Pass through in between a crab many and the quantity of -7, when complex in double 4' and h -- ] -, It'r-ml Italian one-room (7) power is provided in considering it as an arm with large flexibility (6), or 1 Difficulty which is separated from the method of demand Be trimmed 01, and check Place -- this control room (A) -- inside, the distribution power board (8) which fl= business member (3) operates is installed. This 4*! A f'mu board (8) carries out the valve of the Cafe * Le for Suiyui 8 (9) to the above-mentioned remote moving system (4), and is connected, Witches 3 and g" glory f "direction regulation of television camera alpha 0 for surveillance provided in movement of 0:4 Separating device (4), operation of many articulated arms (6), and the above-mentioned remote moving system (4) can be made now to operate a board (8). the monitor TV (11) which monitors the image of the above-mentioned television camera for surveillance (10) is distribution-power-board [ above-mentioned ] (8) K formed -- Si and a worker (3) view this monitor TV (1]), and operate the above-mentioned many articulated arms (6). it is a moat -- these television cameras (10) and monitor TVs alpha 1 can be used also in order to check the position of a remote moving system (4) simultaneously. 0 [ however, ] which the surveillance on a television camera (10) and television (11) may omit when it opts for the check procedure beforehand and there is no necessity for surveillance -- the next, O worker (3) explaining the operation of the example mentioned above operates an operator control panel (8), and makes it run a remote moving system (4) along with the check route which detects Love. And it stops in the part which should be checked, and it is multi-articulated arm (6) all operated, looking at the image of the television camera for surveillance (10) by monitor TV alpha power, 0 which makes an ultrasonic sensor (5) scan the target equipment, apparatus, and the circumference of piping, and checks the existence of disclosure -- such operation is performed one by one about the equipment, apparatus, and piping which make check No (E -- the soundness of a plant -- Fertility -- h To.) It >= Is in the example mentioned above, explains that a remote moving system (4) runs by the table and a ring (4a), and is a /This cam, it may replace with this wheel (4a), and may make it To do walked by 1 Price 14 like the leg of person ifJ] -- it gets by carrying out -- it is (on Point conservation route (a rail may be constructed by zero, and it may be made to carry out Running of the rail top, and may make Crossroads selection according to an operating condition.)) * Although it is considered as the line-of-elevation type through a cable (9) in the example again as a] Akira Emi signal of a remote moving system (4) and an operator control panel (8), it is not limited to this, and it is '1t (it does not have 192-C that it is good in Ri by the radio formula which uses wave-S y Jin, either.). furthermore -- an example -- man -- Late bite ---like -- a 33g work -- it explained on the assumption that it carried out, but the course which :way and many articulated arms (6) scan is beforehand decided to do the remote 4 multi-Exciter t4J power S round of, and even if it runs automatically and detects 1lAJl ., the effect like 1 Boss is produced. If various sensors other than Dim and an ultrasonic sensor (5), such as a temperature sensor, a moisture sensor, a pressure sensor, and a microphone, are carried and those signals are also supervised, not only the surveillance of disclosure but synthetic operation surveillance will be attained. [Effect of the Invention] As mentioned above, it is since according to this invention the ultrasonic sensor was attached at the tip of many articulated arms and these many articulated arms were carried in the remote moving system, without man arranges many detectors also under the adverse environment which cannot enter easily -- remoteness -- safe -- moreover -- Copying -- there is an effect of being able to supervise a few disclosure certainly.
