[0002] The power line is a conductor loop for transmitting and distributing electric energy, and is an important part of the power supply system. In order to ensure the normal work of the electrical equipment, the staff needs to regularly check the power line for faults.

[0003] Through retrieval, a power line fault detection device is disclosed in a patent document with publication number CN118091327B, which includes two mobile seats, and a plurality of linearly arranged fault detection modules are installed on the inner side of each mobile seat.

Figure 1

[0040] Front support 1 and front clamping frame 5 are provided with a plurality of walking assemblies, and the walking assembly is composed of a groove 11, a protrusion 12, a mounting groove 15, a rotating shaft 16, two driving wheels 17 and two compression springs 13.

[0041] ​The transmission mechanism is composed of a rotating rod 19, a driving bevel gear 20, a driven bevel gear 21, a connecting shaft 22, a slot 23, a plug rod 24 and a helical gear 25. The rotating rod 19 is rotatably installed on the convex block 12. The driving bevel gear 20 is fixedly installed on the rotating rod 19. The driven bevel gear 21 is fixedly installed on the rotating shaft 16 and is engaged with the driving bevel gear 20. The connecting shaft 22 is rotatably installed in the recess 11. The slot 23 is formed on the connecting shaft 22. The plug rod 24 is fixedly installed at one end of the rotating rod 19 away from the driving bevel gear 20 and is slidably engaged with the slot 23. The helical gear 25 is fixedly installed at one end of the connecting shaft 22 away from the rotating rod 19. The plug rod 24 and the slot 23 are both square in shape, and the length of the plug rod 24 is greater than the depth of the recess 11. Through the cooperation of the plug rod 24 and the slot 23, the transmission effect between the rotating rod 19 and the connecting shaft 22 can be effectively ensured when the convex block 12 moves in the recess 11. Therefore, no matter where the convex block 12 is located in the recess 11, the rotating rod 19 can be driven to rotate through the rotation of the connecting shaft 22, and then the rotating shaft 16 is driven to rotate through the cooperation of the driving bevel gear 20 and the driven bevel gear 21, so that the device can move on the power line, and thus the electromagnetic induction detector 4 can complete the fault positioning detection of the entire power line.

[0042] A plurality of recesses 11 are also formed in the inner walls of the rear support 2 and the rear clamping frame 6, and a convex block 12 is slidably installed in each recess 11 through two compression springs 13.

Two limiting grooves corresponding to the limiting blocks 14 are formed in the side wall of the recess 11. The design of the plurality of convex blocks 12 on the rear support 2 and the rear clamping frame 6 can further improve the installation stability of the device on the power line. The design of the driven wheel 18 can reduce the moving resistance of the device on the power line, making it move more smoothly.

[0043] A general control assembly cooperating with a plurality of walking assemblies is jointly installed between the front support 1 and the front clamping frame 5. The general control assembly is used for driving and processing the plurality of walking assemblies. The general control assembly is composed of two rotating grooves 26, two arc-shaped plates 27 and two inclined gear rings 28. The two rotating grooves 26 are respectively formed in the front support 1 and the front clamping frame 5 and are spliced into a complete annular shape. The two arc-shaped plates 27 are rotatably installed in the two rotating grooves 26. The two inclined gear rings 28 are fixedly installed on the side walls of the two arc-shaped plates 27 and are engaged with the plurality of helical gears 25. When the device is in the working state, the two arc-shaped plates 27 are driven to rotate through the plurality of helical gears 25 and the plurality of walking assemblies, so that the device can move on the power line. Figure 1In the shown state, the two arc-shaped plates 27 are spliced into a complete ring, and the rotation of the two arc-shaped plates 27 can drive the plurality of bevel gears 25 to rotate simultaneously through the two inclined gear rings 28, so that the plurality of driving wheels 17 rotate simultaneously to drive the movement of the device on the power line.

[0044] The cleaning assembly is used for cleaning the power line, and is composed of two arc-shaped grooves 29, two arc-shaped frames 30 and a plurality of cleaning rods 31. The two arc-shaped grooves 29 are respectively formed in the front support 1 and the front clamping frame 5, and are spliced into a complete ring. The two arc-shaped frames 30 are rotatably installed in the two arc-shaped grooves 29, and a plurality of cleaning rods 31 are fixedly installed on the inner walls of the two arc-shaped frames 30. When the device is closed and installed, the two arc-shaped frames 30 also form a complete ring. At this time, the rotation of the two arc-shaped frames 30 can drive the plurality of cleaning rods 31 to rotate, so that they perform circular motion relative to the power line. In cooperation with the movement of the device, the surface of the power line is cleaned in advance during the detection process to remove dust, bird droppings and other impurities, thereby improving the accuracy of the subsequent detection results. In order to ensure the normal unfolding and closing of the device, the two arc-shaped plates 27 and the two arc-shaped frames 30 can be rotated by starting the servo motor 38 before and after use, so as to be located in the corresponding rotating grooves 26 and arc-shaped grooves 29 respectively.

[0045] The moving assembly cooperated with the electromagnetic induction detector 4 is installed between the front support 1 and the rear support 2, and is used for moving the electromagnetic induction detector 4 between the front support 1 and the rear support 2. The moving assembly is composed of a reciprocating screw 3 and a connecting gear 37. The reciprocating screw 3 is rotatably installed between the front support 1 and the rear support 2, and is threadedly connected with the electromagnetic induction detector 4. The connecting gear 37 is fixedly installed on one end of the reciprocating screw 3 located in the front support 1. When the device detects a fault during movement along the power line, the device remains stationary on the power line, and then the reciprocating screw 3 is rotated to move the electromagnetic induction detector 4 between the front support 1 and the rear support 2 once, i.e. to detect the part of the power line with the fault twice, so as to better locate the fault point accurately. Since the front support 1 and the rear support 2 remain stationary during the movement of the electromagnetic induction detector 4, the part of the power line between them also remains stationary, so that the problem of affecting the accuracy of the detection result due to the shaking of the power line can be avoided. When the electromagnetic induction detector 4 completes the reciprocating movement and returns to the original position, the device continues to move on the power line until the overall fault detection of the power line is completed.

[0046] The driving assembly is installed in the front support 1 and cooperates with the general control assembly, the cleaning assembly and the moving assembly. The driving assembly can drive only the moving assembly or the general control assembly and the cleaning assembly at the same time (the driving assembly is configured to execute only one of the following driving operations at the same time: a) driving the moving assembly; b) driving the general control assembly and the cleaning assembly at the same time). The driving process of the driving assembly on the moving assembly or the general control assembly and the cleaning assembly is controlled by the electromagnetic induction detector 4. The driving of the driving assembly on the moving assembly or the general control assembly and the cleaning assembly is automatically switched according to the result of the initial detection of the electromagnetic induction detector 4. When a fault signal is initially detected during the movement of the device along the power line, the driving assembly is switched from driving the general control assembly and the cleaning assembly to driving the moving assembly, and after driving the moving assembly for a certain period of time, the driving assembly is automatically switched again to drive the general control assembly and the cleaning assembly. The working time of the moving assembly is defined as the time for the electromagnetic induction detector 4 to complete one complete reciprocating movement between the front support 1 and the rear support 2.

[0047] The driving assembly is composed of a driving shaft 32, a first gear 33, a second gear 35, a servo motor 38, a driving rod 39, a pinion 41, a large gear 42 and a fixed gear 43. The driving shaft 32 is rotatably installed in the front support 1. The first gear 33 and the second gear 35 are fixedly installed at both ends of the driving shaft 32. A first rack 34 is fixedly installed on the side wall of the arc-shaped plate 27 and engaged with the first gear 33. A second rack 36 is fixedly installed on the side wall of the arc-shaped frame 30 and engaged with the second gear 35. When the driving shaft 32 rotates, the first gear 33 and the second gear 35 are driven to rotate simultaneously. Then, through the engagement of the first gear 33 and the first rack 34 and the engagement of the second gear 35 and the second rack 36, the two arc-shaped plates 27 and the two arc-shaped frames 30 are driven to rotate simultaneously, thereby driving the walking assembly and the cleaning assembly to operate simultaneously, so that the device moves along the power line and simultaneously cleans the area to be detected.

[0048] The first gear 33, the second gear 35 and the fixed gear 43 have the same size, and the diameter of the first rack 34 is greater than that of the second rack 36. The advantage of this size design is that the cleaning rod 31 can have a higher rotating speed, so that it can effectively cover the area to be detected of the power line during the movement of the device along the power line, thereby ensuring the cleaning effect of the power line.

[0049] The fixed gear 43 is fixedly installed on the driving shaft 32, the servo motor 38 is fixedly installed in the front support 1, the driving rod 39 is fixedly installed on the output end of the servo motor 38, the pinion 41 is installed on the driving rod 39 and matches with the connecting gear 37, the gear wheel 42 is fixedly installed on the pinion 41 and matches with the fixed gear 43, the electric push-pull rod 44 is fixedly installed in the front support 1 and the output end of the electric push-pull rod 44 is in rotary cooperation with the gear wheel 42, the telescopic slot is formed in the driving rod 39, the telescopic rod 40 is fixedly installed on the pinion 41 and is in sliding cooperation with the telescopic slot, when the gear wheel 42 meshes with the fixed gear 43, the pinion 41 is in a separated state with the connecting gear 37, at this time, the work of the servo motor 38 can drive the driving shaft 32 to rotate, driving the movement assembly and the cleaning assembly to run, when the electromagnetic induction detector 4 detects a fault signal, the electric push-pull rod 44 starts to extend, making the gear wheel 42 separate from the fixed gear 43 and making the pinion 41 mesh with the connecting gear 37, at this time, the work of the servo motor 38 makes the movement assembly run, and because of the size difference between the gear wheel 42 and the pinion 41, under the condition that the output power of the servo motor 38 is unchanged, the running speed of the movement assembly is lower, so the reciprocating speed of the electromagnetic induction detector 4 between the front support 1 and the rear support 2 is lower, which can more accurately locate the fault point on the power line under low speed.

[0050] In order to ensure that the electric push-pull rod 44 pushes the gear wheel 42 when the electromagnetic induction detector 4 detects a fault signal for the first time, a control chip can be installed in the front support 1, which is used for receiving the detection signal of the electromagnetic induction detector 4 and controlling the operation of the electric push-pull rod 44 through signal transmission, realizing the automatic switching of the operation mode of the device, wherein the signal connection and signal processing mode of the control chip with the electromagnetic induction detector 4 and the electric push-pull rod 44 are prior art, so they are not described in detail, and because the servo motor 38 is arranged, the reciprocating screw 3 can adopt a simple one-way screw, which only needs to work in the output direction for a certain time after detecting the fault signal for the first time, and the specific control mode is also prior art, which is not described in detail here, the servo motor 38 can specifically adopt a servo motor of MGX1MB01A010AS type, in addition, if it is required to avoid the magnetic field around the power line from interfering with the control signal, electromagnetic shielding paint or other anti-electromagnetic interference measures can be applied on the device according to actual needs.

Those skilled in the art should understand that the present application is not limited to the above-mentioned embodiments, and the above-mentioned embodiments and descriptions in the specification are only to illustrate the principles of the present application.
