Description

Technical Field

[0001] This utility model relates to the field of insulator testing technology, and in particular to a high-voltage insulator testing robot. Background Technology

[0002] High-voltage insulators may experience deterioration, cracking, or even breakdown during operation, seriously threatening the safe operation of the power system. Therefore, insulators need to be inspected regularly. Currently, the inspection of insulator strings is mainly done manually. Manual inspection has disadvantages such as low efficiency, high risk, and high labor intensity. Moreover, with the continuous development of my country's power system, voltage levels are getting higher and higher, and the length of insulator strings is also getting longer. Manual inspection can no longer meet the inspection requirements of ultra-high voltage lines.

[0003] A high-voltage insulator inspection robot is disclosed in prior art patent application CN 217212970 U. This utility model employs a mounting plate and a limiting plate, enabling the inspection robot to move more stably and safely on insulators during inspection. This device can be used in conjunction with drones to inspect transmission lines at locations such as suspension bridges, meeting the inspection requirements of ultra-high voltage lines. It is highly adaptable and has a wide range of applications. The high-voltage insulator inspection robot is a double-span insulator string robot, which moves more stably in high-altitude and windy environments, overcoming the instability problem of single-span insulators.

[0004] Some high-voltage insulators are installed by vertical hoisting, but in the existing technology, this device cannot move on the suspension insulator and cannot inspect the suspension insulator, resulting in low practicality of the device. Utility Model Content

[0005] The purpose of this invention is to provide a high-voltage insulator inspection robot, which aims to solve the problem that some high-voltage insulators are installed by vertical hoisting, but in the prior art, the device cannot move on the suspension insulator and cannot inspect the suspension insulator, resulting in low practicality of the device.

[0006] To achieve the above objectives, this utility model provides a high-voltage insulator inspection robot, including a moving mechanism and an inspection device body. The moving mechanism includes a mounting frame, a drive assembly, a moving block, a fixed frame, a clamping assembly, two mounting blocks, and two arc-shaped clamping plates. The drive assembly is mounted on the mounting frame, the moving block is mounted on the output end of the drive assembly, the fixed frame is fixedly connected to the moving block, the clamping assembly is mounted on the fixed frame, the two mounting blocks are mounted on the output end of the clamping assembly and are slidably connected to the fixed frame, and the two arc-shaped clamping plates are respectively fixedly connected to one end of the two mounting blocks. The inspection device body is respectively mounted on the two arc-shaped clamping plates.

[0007] The drive assembly includes a drive motor and a threaded rod. The drive motor is fixedly connected to one end of the mounting bracket, the threaded rod is fixedly connected to the output end of the drive motor and extends into the mounting bracket, and the moving block is threadedly connected to the threaded rod.

[0008] The drive assembly further includes a guide post and a limiting block. The limiting block is fixedly connected to one end of the moving block, and both ends of the guide post are fixedly connected to the mounting bracket. The guide post is slidably connected to the limiting block and passes through the limiting block.

[0009] The clamping assembly includes a rotary motor, a first lead screw, and a second lead screw. The rotary motor is fixedly connected to the fixed frame. One end of the first lead screw is fixedly connected to the output end of the rotary motor. The second lead screw is fixedly connected to the other end of the first lead screw and is located inside the fixed frame. The two mounting blocks are threadedly connected to the first lead screw and the second lead screw, respectively.

[0010] The moving mechanism further includes a locking block, one of the arc-shaped clamps having a locking groove, the locking block being fixedly connected to the other arc-shaped clamp, and the locking block being slidably connected to the locking groove.

[0011] This utility model discloses a high-voltage insulator inspection robot. The mounting frame is fixed on the power line frame and located on one side of the suspension insulator. When inspecting the suspension insulator, the driving component drives the moving block and two arc-shaped clamps to move up and down. When the inspection device body moves to the appropriate position, the driving component stops moving the moving block, and the clamping component controls the two arc-shaped clamps to clamp the insulator. The inspection device body inspects the insulator. After the insulator inspection is completed, the clamping component controls the two arc-shaped clamps to move to both sides, and the driving component moves the two arc-shaped clamps to the next inspection position, thereby inspecting the suspension insulator and improving the practicality of the device.

Detailed Implementation

[0018] Please see Figures 1 to 4 ,in, Figure 1 This is a structural schematic diagram of the high-voltage insulator testing robot of this utility model. Figure 2 This is the utility model Figure 1 Enlarged view of the local structure at point A. Figure 3 This is a structural schematic diagram of the high-voltage insulator inspection robot of this utility model from another direction. Figure 4 This is a front view of the high-voltage insulator testing robot of this utility model.

[0019] This utility model provides a high-voltage insulator inspection robot, including a moving mechanism and an inspection device body 111. The moving mechanism includes a mounting frame 101, a drive assembly, a moving block 104, a locking block 112, a fixing frame 105, a clamping assembly, two mounting blocks 109, and two arc-shaped clamping plates 110. The drive assembly includes a guide post 114, a limiting block 115, a drive motor 102, and a threaded rod 103. The clamping assembly includes a rotary motor 106, a first lead screw 107, and a second lead screw 108. One of the arc-shaped clamping plates 110 has a slot 113. The aforementioned solution solves the problem that some high-voltage insulators are installed by vertical hoisting. However, in the prior art, this device cannot move on suspension insulators and cannot inspect suspension insulators, resulting in low practicality of the device.

[0020] In this embodiment, the driving assembly is mounted on the mounting frame 101, the moving block 104 is mounted on the output end of the driving assembly, the fixed frame 105 is fixedly connected to the moving block 104, the clamping assembly is mounted on the fixed frame 105, two mounting blocks 109 are mounted on the output end of the clamping assembly and slidably connected to the fixed frame 105, two arc-shaped clamping plates 110 are respectively fixedly connected to one end of the two mounting blocks 109, the detection device body 111 is respectively mounted on the two arc-shaped clamping plates 110, and the mounting frame 101 is fixed on the wire frame and located on one side of the suspension insulator. When testing suspension insulators, the driving assembly moves the moving block 104 and the two arc-shaped clamping plates 110 up and down. When the testing device body 111 moves to the appropriate position, the driving assembly stops moving the moving block 104 and controls the two arc-shaped clamping plates 110 to clamp the insulator through the clamping assembly. The testing device body 111 tests the insulator. After the insulator test is completed, the clamping assembly controls the two arc-shaped clamping plates 110 to move to both sides, and the driving assembly moves the two arc-shaped clamping plates 110 to the next testing position. This process is used to test suspension insulators, thereby improving the practicality of the device.

[0021] Furthermore, the drive motor 102 is fixedly connected to one end of the mounting bracket 101, the threaded rod 103 is fixedly connected to the output end of the drive motor 102 and extends into the mounting bracket 101, and the moving block 104 is threadedly connected to the threaded rod 103.

[0022] Furthermore, the limiting block 115 is fixedly connected to one end of the moving block 104, the two ends of the guide post 114 are fixedly connected to the mounting bracket 101, the guide post 114 is slidably connected to the limiting block 115, and passes through the limiting block 115.

[0023] In this embodiment, when the moving block 104 is controlled to move up and down, the drive motor 102 is started. The drive motor 102 drives the threaded rod 103 to rotate, and the moving block 104 moves up and down on the threaded rod 103. At the same time, the limiting block 115 slides on the guide post 114, which plays a limiting and guiding role on the movement of the moving block 104 and the detection device body 111, ensuring that the moving block 104 will not be misaligned or tilted during the movement.

[0024] Furthermore, the rotary motor 106 is fixedly connected to the fixed frame 105, one end of the first lead screw 107 is fixedly connected to the output end of the rotary motor 106, the second lead screw 108 is fixedly connected to the other end of the first lead screw 107 and is located inside the fixed frame 105, and the two mounting blocks 109 are threadedly connected to the first lead screw 107 and the second lead screw 108 respectively.

[0025] Furthermore, the card block 112 is fixedly connected to another arc-shaped clamping plate 110, and the card block 112 is slidably connected to the card slot 113.

[0026] In this embodiment, when the two arc-shaped clamping plates 110 clamp the insulator, the rotary motor 106 is started. The rotary motor 106 drives the first lead screw 107 and the second lead screw 108 to rotate. Since the threads of the first lead screw 107 and the second lead screw 108 are opposite, the two arc-shaped clamping plates 110 move in mirror image. The rotary motor 106 controls the two arc-shaped clamping plates 110 to move towards the center until the locking block 112 is engaged in the locking slot 113. At this time, the two arc-shaped clamping plates 110 clamp the insulator so that the detection device body 111 can detect the insulator.

[0027] The mounting bracket 101 of this utility model is fixed on the power line frame and located on one side of the suspension insulator. When testing the suspension insulator, the drive motor 102 drives the moving block 104 and the two arc-shaped clamping plates 110 to move up and down. When the testing device body 111 moves to the appropriate position, the drive motor 102 stops moving the moving block 104, and the rotary motor 106 controls the two arc-shaped clamping plates 110 to clamp the insulator. The testing device body 111 tests the insulator. After the insulator is tested, the rotary motor 106 controls the two arc-shaped clamping plates 110 to move to both sides, and the drive motor 102 moves the two arc-shaped clamping plates 110 to the next testing position. This process is used to test the suspension insulator, thereby improving the practicality of the device.
