[0015] The present invention has the following beneficial effects:

[0016] 1. In the installation structure of the power transmission line fault location device, when the fault location device body is installed, the first guide wheel and the second guide wheel cooperate with each other to clamp the power transmission line, so that the worker only needs to complete the installation of the fault location device body on the line tower, and then rotate the first guide wheel to make the first guide wheel and the second guide wheel move along the power transmission line, so as to facilitate the automatic installation of the fault location device body to a suitable position, avoid the safety problem when the worker climbs onto the power transmission line for installation, and reduce the difficulty of installation; When the fault locating device body moves along the transmission line, the first guide wheel drives the disc to rotate, and the disc drives the first piston plate to reciprocate left and right inside the movable cavity through the transmission rod. When the first piston plate reciprocates left and right, it can push the pressure plate to move, so that the pressure plate drives the arc rod to move, the arc rod drives the slider to move, and the slider drives the arc plate to move, so as to separate the conductive rubber sheet from the transmission line, thereby avoiding wear between the conductive rubber sheet and the transmission line when the fault locating device body moves.

[0017] 2. In the installation structure of the transmission line fault location device, when the first piston plate reciprocates left and right inside the active cavity, the first piston plate and the active cavity generate friction, so that the inner wall temperature of the active cavity rises to a certain temperature. At this time, the heat conduction plate transfers the temperature to the filling liquid tank, so that the liquid inside the filling liquid tank expands, and at the same time drives the second piston plate to move. The second piston plate drives the third push rod to move, so that the third push rod resists the arc rod. The third push rod provides thrust to the arc rod, making the arc rod more stable, avoiding the arc rod from shaking back and forth, thereby avoiding the arc plate and the conductive rubber sheet from shaking back and forth, increasing the stability of the structure, and helping to reduce the loss of the structure; Through the interference between the third push rod and the arc rod, the reciprocating motion of the pressure plate will not cause the conductive rubber sheet to shake, thereby avoiding accidental contact between the conductive rubber sheet and the transmission line, effectively preventing the wear of the conductive rubber sheet, and further increasing the protection of the conductive rubber sheet.

[0018] 3. In the installation structure of the power transmission line fault locating device, when exhausting at the air outlet, the gas enters the first hollow inner plate through the air guide pipe, and then docks with the plug interface through the plug connector to introduce the gas into the second hollow inner plate, and then blows to the surface of the power transmission line through a plurality of groups of blowing holes, so as to facilitate the removal of dust and impurities on the power transmission line. At the same time, when blowing air through the blowing holes, the disc rotates to make the boss slide in the serrated ring groove, so that the boss can drive the slide bar to reciprocate left and right, and the left and right reciprocating motion of the slide bar drives the lever to reciprocate back and forth, so that the first hollow inner plate and the second hollow inner plate perform forward and reverse reciprocating motion, so that the blowing holes have a wider range of blowing on the power transmission line, thereby further improving the blowing effect.

A limiting ball 37 is fixed at the end of the connecting rod 18 , and the limiting ball 37 is slidably provided in the limiting groove 36 .

[0034] In the present technical scheme, when the fault location device body 1 is installed on the transmission line, first, the first guide wheel 3 and the second guide wheel 4 are separated, so that the transmission line passes through the upper surface of the first guide wheel 3, and the transmission line passes through the two sets of arc plates 6, and then the first protrusion 24 and the second protrusion 25 are fixed by the first fastening bolt 26, so that the second guide wheel 4 cooperates with the first guide wheel 3 to clamp the transmission line, and then the screw 28 is rotated to make the screw 28 drive the clamping plate 29 to move, the clamping plate 29 drives the first spring 30 to move, the first spring 30 drives the arc plate 6 to move, and the arc plate 6 drives the conductive rubber sheet 7 to move, so that the conductive rubber sheets 7 on both sides are engaged with the outer surface of the transmission line, and the conductive rubber sheets 7 are fixed, and finally the cover plate of the fault location device body 1 is covered, so that the fault location device body 1 is installed on the transmission line; and the conductive rubber sheet 7 is connected to the transmission line with equal potential by crimping the conductive rubber and galvanized conductor, which belongs to the prior art and is not described in detail; By starting the servo motor 19, the servo motor 19 drives the first rotating shaft 21 to rotate, and the first rotating shaft 21 drives the first guide wheel 3 to rotate, so that the first guide wheel 3 moves on the transmission line, which facilitates the movement of the fault location device body 1 to a suitable position on the transmission line; when the first guide wheel 3 rotates to drive the fault location device body 1 to move on the transmission line, Figure 5 and Figure 6 As shown, the rotation of the first guide wheel 3 drives the disc 8 to rotate, and the rotation of the disc 8 drives the transmission rod 9 to move back and forth left and right, and the reciprocating movement of the transmission rod 9 drives the first piston plate 12 to reciprocate left and right in the active chamber 10; like Figure 6 As shown, first, when the transmission rod 9 moves to the right, the transmission rod 9 drives the first piston plate 12 to move to the right in the active chamber 10, and the first piston plate 12 moves to the right to discharge the gas inside the active chamber 10 from the gas outlet 32. Since the gas outlet 32 ​​is small, the gas discharge speed is slow. At this time, the gas will squeeze the pressure plate 13, and the pressure plate 13 will move to the right. The second spring 33 is compressed and stored. The pressure plate 13 moves to the right and drives the first push rod 15 to move to the right. The first push rod 15 pushes the arc rod 14 to move to the right. The third spring 34 is compressed and stored. The arc rod 14 moves to the right and drives the second push rod 16 to move to the right. , the second push rod 16 moves rightward and drives the slider 17 to move rightward, so that the connecting rod 18 slides in the slideway 35, and the connecting rod 18 drives the limiting ball 37 to slide in the limiting groove 36. Since the limiting groove 36 is inclined, the limiting ball 37 drives the sliding rod 53 to move downward, and the sliding rod 53 moves downward to pull the arc plate 6 to move downward, and at the same time compresses the first spring 30, so that the first spring 30 accumulates force. At this time, the movement of the arc plate 6 drives the conductive rubber sheet 7 to move, so that the conductive rubber sheet 7 is no longer in contact with the power transmission line, thereby reducing the wear of the conductive rubber sheet 7 when the fault location device body 1 moves on the power transmission line; When the transmission rod 9 moves to the left, it drives the first piston plate 12 to move to the left, and air is taken in through the air inlet 31. The pressure plate 13 loses the extrusion of gas, and the second spring 33 releases force, so that the pressure plate 13 has a tendency to reset to the left. However, due to the large diameter of the air inlet 31, the air intake can be completed instantly, so that the speed at which the first piston plate 12 is reset to the left is greater than the speed at which the pressure plate 13 is reset to the left. Therefore, when the first piston plate 12 moves to the right again, although the pressure plate 13 moves to the left, it is not completely reset. After that, it will be squeezed by the gas again and continue to move to the right, so that during the movement of the fault location device body 1, the conductive rubber sheet 7 will not contact the power transmission line. When the fault location device body 1 moves to the appropriate position, the servo motor 19 stops, and the first piston plate 12 also stops moving. At this time, the second spring 33 can drive the pressure plate 13 to reset to the initial state, so that the conductive rubber sheet 7 can contact the power transmission line again to perform normal fault location work. In the present technical scheme, a first one-way valve is arranged in the air inlet 31, and a second one-way valve is arranged in the air outlet 32. The first one-way valve allows gas to enter the active chamber 10 only from the air inlet 31 but not to be discharged from the air inlet 31. The second one-way valve allows gas to be discharged only from the air outlet 32 ​​but not to enter from the air outlet 32. The first one-way valve and the second one-way valve are both existing technologies and are not described in detail. In addition, the opening of the air inlet 31 is larger and the opening of the air outlet 32 ​​is smaller, so that when the first piston plate 12 makes a left-right reciprocating motion in the active chamber 10, the air intake efficiency is high and the exhaust efficiency is slow, so that the pressure plate 13 will also make a certain amplitude of left-right reciprocating motion, but the pressure plate 13 will not reset to the initial position. Therefore, when the first piston plate 12 makes a left-right reciprocating motion in the active chamber 10, the conductive rubber sheet 7 will not contact the power transmission line; and a solar panel can be arranged on the cover plate of the fault locating device body 1 to power the servo motor 19, so as to facilitate remote control of the start and stop of the servo motor 19.

[0035] In the second embodiment, although the conductive rubber sheet 7 does not contact the transmission line when the fault location device body 1 moves on the transmission line, the first piston plate 12 drives the pressure plate 13 to reciprocate left and right, so that the structure is always in a reciprocating state when moving, making the internal structure extremely unstable, thereby increasing the loss of the structure. To solve this problem, this embodiment is an improvement made on the basis of the first embodiment. For details, please refer to Figure 1-Figure 12 A filling liquid tank 38 is provided inside the fault location device body 1, a heat conducting plate 39 is provided between the active cavity 10 and the filling liquid tank 38, a second piston plate 40 is slidably provided in the filling liquid tank 38, a third push rod 41 is fixed on the second piston plate 40, the other end of the third push rod 41 is in contact with the surface of the arc plate 6, and the third push rod 41 is slidably provided in the fault location device body 1; In the present technical solution, when the first piston plate 12 reciprocates left and right inside the active cavity 10, the first piston plate 12 will generate friction with the surface of the active cavity 10, so that the temperature of the inner wall of the active cavity 10 increases. At this time, heat is conducted through the heat conducting plate 39, so that the temperature inside the filling liquid tank 38 increases. The filling liquid tank 38 is filled with liquid, and the liquid has temperature sensing properties. When the temperature rises, it can expand and deform, and when the temperature drops, it can recover. Specifically, it can be mercury; at the same time, when the first piston plate 12 reciprocates left and right inside the active cavity 10, the first piston plate 12 will also compress the gas inside the active cavity 10. Using the principle that compressed gas can also generate heat, the temperature of the inner wall of the active cavity 10 will also increase, thereby increasing the temperature inside the filling liquid tank 38. Specifically, when the gas is compressed, the outside world applies energy to the gas, the distance between molecules becomes smaller, and the collisions between molecules become more frequent and intense, thereby generating heat, resulting in The temperature rises; when the temperature inside the filling tank 38 rises, the liquid expands, pushing the second piston plate 40 to move rightward, and the second piston plate 40 moves rightward to drive the third push rod 41 to move rightward, and the third push rod 41 pushes the arc rod 14 to move rightward, pushing the arc rod 14 to the farthest right. At this time, the third push rod 41 provides a stable thrust, and the arc rod 14 no longer needs the pressure plate 13 and the first push rod 15 to provide thrust, so that the arc rod 14 will not continue to reciprocate left and right, so that the slider 17, the arc plate 6 and the conductive rubber sheet 7 will no longer reciprocate, thereby increasing the stability of the structure and further reducing the loss of the internal structure; at the same time, the arc rod 14 is pushed by the third push rod 41, so that the conductive rubber sheet 7 is more stable when separated from the transmission line, effectively avoiding the accidental contact between the conductive rubber sheet 7 and the transmission line due to the shaking of the conductive rubber sheet 7 during the movement, and effectively preventing the wear of the conductive rubber sheet 7.

[0036] Embodiment 3: After the fault location device body 1 moves on the transmission line and moves to a suitable position, when the conductive rubber sheet 7 clamps and covers the transmission line again, there may be some dust and impurities on the transmission line, so that the conductive rubber sheet 7 covers it inside all the time, which may cause adverse effects on normal use. To address this problem, this embodiment is an improvement made on the basis of embodiment 2. For details, please refer to Figure 1-Figure 12A second positioning plate 42 is fixed to the outer side of the first positioning plate 2, a first clamping plate 43 is fixed to the upper surface of the second positioning plate 42, a first hollow inner plate 44 is slidably provided on the first clamping plate 43, a second clamping plate 45 is provided above the first clamping plate 43, a second hollow inner plate 46 is slidably provided on the inner side of the second clamping plate 45, a plurality of groups of blowing holes 47 are provided on the first hollow inner plate 44 and the second hollow inner plate 46, an air guide 48 is provided between the air inlet 31 and the first hollow inner plate 44, a plug interface 49 is provided on the first hollow inner plate 44, and a plug connector 50 for inserting into the plug interface 49 is fixed on the second hollow inner plate 46; A sawtooth annular groove 51 is provided on the inner surface of the disc 8, a boss 52 is slidably provided inside the sawtooth annular groove 51, a sliding rod 53 is fixed to the end of the boss 52, the other end of the sliding rod 53 is slidably connected to the second positioning plate 42, a first trapezoidal block 54 and a second trapezoidal block 55 are slidably provided inside the second positioning plate 42, one end of the first trapezoidal block 54 is fixedly connected to the sliding rod 53, a straight rod 56 is fixed to one end of the second trapezoidal block 55, a through groove 57 is provided on the lower surface of the first clamping plate 43, a lever 58 is slidably provided in the through groove 57, one end of the lever 58 is fixed to the outer surface of the first hollow inner plate 44, the other end of the lever 58 is in conflict with the straight rod 56, and a fourth spring 59 is fixed between the lever 58 and the inner wall of the second positioning plate 42; A third protrusion 60 is fixed to the outer surface of the first clamping plate 43 , a fourth protrusion 61 is fixed to the outer surface of the second clamping plate 45 , and a second fastening bolt 62 is threadedly connected between the third protrusion 60 and the fourth protrusion 61 .

[0037] In the technical solution, after the first guide wheel 3 and the second guide wheel 4 clamp the transmission line, the second clamping plate 45 is arranged above the first clamping plate 43, so that the transmission line is located between the first hollow inner plate 44 and the second hollow inner plate 46, and then the third protrusion 60 and the fourth protrusion 61 are fixed by the second fastening bolt 62, so that the third protrusion 60 and the fourth protrusion 61 are in conflict, and the connection between the second clamping plate 45 and the first clamping plate 43 is completed. At this time, the plug connector 50 on the second hollow inner plate 46 is inserted into the first hollow inner plate 44. The plug connector 49 on the upper side is inserted into the plug connector 50, and the plug connector 50 is kept sealed with the plug connector 49. At this time, when the gas outlet 32 ​​is exhausted, the gas enters the first hollow inner plate 44 through the air guide tube 48, and then enters the second hollow inner plate 46 through the plug connector 50, and finally blows out through the blowing hole 47, blowing the gas to the surface of the power transmission line, so as to facilitate the blowing away of dust and foreign matter on the surface of the power transmission line, and prevent the conductive rubber sheet 7 from clamping and covering the power transmission line again, and preventing the presence of more dust on the covered power transmission line, which will cause adverse effects on the equipment; When the blowing hole 47 is blowing, the disc 8 rotates to drive the protruding column 52 to slide inside the sawtooth ring groove 51, so that the protruding column 52 can reciprocate left and right. Fig.10As shown, when the protruding column 52 reciprocates left and right, it drives the sliding rod 53 to reciprocate left and right, and the reciprocating movement of the sliding rod 53 drives the first trapezoidal block 54 to reciprocate left and right. Through the action of the fourth spring 59, the second trapezoidal block 55 can reciprocate back and forth. The second trapezoidal block 55 drives the lever 58 to reciprocate back and forth through the straight rod 56, so that the lever 58 drives the first hollow inner plate 44 and the second hollow inner plate 46 to rotate forward and reverse inside the first clamping plate 43 and the second clamping plate 45, so that the blowing angles of the plurality of blowing holes 47 can be adjusted, so that the blowing holes 47 have a wider range of blowing on the transmission line, thereby improving the blowing effect; In the present technical solution, a card slot 63 is provided on the first card plate 43 and the second card plate 45, and a card block 64 is fixed on the first hollow inner plate 44 and the second hollow inner plate 46. The card block 64 is slidably set in the card slot 63, so that when the lever 58 drives the first hollow inner plate 44 and the second hollow inner plate 46 to rotate, the first hollow inner plate 44 and the second hollow inner plate 46 can only rotate relative to the first card plate 43 and the second card plate 45, and no displacement will occur.
