Description

Technical Field

[0001] This invention relates to the field of cable testing technology, and in particular to a device for detecting damage to power cables. Background Technology

[0002] Power cables are composed of conductors, insulation layers, shielding layers, and sheaths. They are used to transmit and distribute electrical energy and can be buried underground, laid in conduits, or cable trays. They provide stable power supply and high safety. Damage to the surface insulation layer of power cables can easily lead to leakage, short circuits, and power outages. Timely testing before leaving the factory can identify potential hazards in advance, reduce operation and maintenance costs, and ensure the safe and reliable operation of the power grid.

[0003] In existing technologies, when performing damage detection on power cables, in order to avoid the influence of dust on the cable surface on the imaging accuracy, the power cables are brushed in a cleaning tank before entering the testing mechanism for testing. Therefore, in the actual testing process, the operator needs to take the end of the power cable to be tested and guide it through the brushing and dehydration mechanism in sequence, which is relatively cumbersome. Especially when passing through the brushing mechanism, the passing operation needs to be carried out below the surface of the cleaning liquid, which is difficult to implement and has a significant impact on the testing efficiency.

[0004] Therefore, it is necessary to invent a power cable damage detection device to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a power cable damage detection device that allows for a more convenient cable insertion operation during power cable testing. This simplifies the operation steps, reduces implementation difficulty, and improves testing efficiency. It addresses the problem mentioned in the background art where, during actual testing, operators need to hold the end of the power cable to be tested and guide it through the brushing and dewatering mechanisms, which is relatively cumbersome. Especially when passing through the brushing mechanism, the insertion operation needs to be performed below the cleaning liquid level, making implementation difficult and significantly impacting testing efficiency.

The rotating disk is fixedly connected to the intermediate shaft, and the torsion spring is fixedly connected between the rotating disk and the end plate. The end plate is rotatably connected to the intermediate shaft via a ball bearing. The front of the rotating disk has two concentric arc-shaped clearance grooves. The end of each arc-shaped clearance groove is connected to a traction groove also located on the front of the rotating disk. An outer sleeve is sleeved on the outer side of the torsion spring. The rear end of the outer sleeve is fixedly connected to the rotating disk, and the front end of the outer sleeve is nested on the back of the end plate via a ball bearing. An arc-shaped push plate is fixedly connected to the left side of the outer sleeve.

[0007] Preferably, the cable end clamping mechanism includes an L-shaped arm fixedly connected to the left end of the back of the end plate, a clamping plate A fixedly connected to the front end of the L-shaped arm, a sliding shaft slidably arranged on the inner side of the L-shaped arm along the horizontal direction via a linear bearing, a pull rod fixedly connected to the left end of the sliding shaft, a clamping plate B fixedly connected to the front end of the pull rod, and an elastic reset member fixedly connected between the L-shaped arm and the pull rod sleeved on the outer side of the sliding shaft.

[0008] Preferably, the bottom, right side and top of the inner cavity of the cleaning tank are all provided with guide concave wheels A through a pin, and a cleaning liquid inlet pipe and a cleaning liquid outlet pipe are fixedly and continuously installed on the right side of the cleaning tank from top to bottom.

[0009] Preferably, the three-way detection mechanism includes a fixed frame fixedly installed on the top left side of the cleaning tank. A guide wheel B is rotatably nested inside the fixed frame via a pin. Three sets of detection components located on top of the guide wheel B are evenly fixed inside the fixed frame, and a power cable entry channel is formed between the three sets of detection components.

[0010] Preferably, any group of the detection components includes a fixed column that is fixed through the fixed frame, an mounting plate is fixedly connected to the inner end of the fixed column, and a camera and multiple supplementary lights are fixedly installed on the side of the mounting plate away from the fixed column.

[0011] Preferably, the brushing mechanism includes an upper cleaning brush that is fixedly nested at the bottom of the front side of the inner cavity of the cleaning tank, and a lower cleaning brush is provided at the bottom of the upper cleaning brush. An avoidance channel A is formed between the upper cleaning brush and the lower cleaning brush to avoid the cable end clamping mechanism.

[0012] Preferably, the rear end of the top of the lower cleaning brush is slidably provided with a guide shaft A through the vertical direction via a linear bearing and is fixedly connected to the inner wall of the cleaning tank.

The traction rod B is slidably provided at the end of the adjacent arc-shaped clearance groove away from the corresponding traction groove.

[0015] The technical effects and advantages of this invention are as follows: This invention incorporates a rotating traction mechanism and a cable end clamping mechanism. After the cable end clamping mechanism secures the end of the power cable under test, the rotating traction mechanism drives it to rotate counter-clockwise. This allows the cable end clamping mechanism to pull the end of the power cable under test through the washing and dewatering mechanisms. Subsequently, due to the obstruction of the cleaning guide mechanism, the rotating traction mechanism releases the cable end clamping mechanism, while the washing and dewatering mechanisms complete the wrapping of the power cable under test. This ensures the smooth progress of subsequent cleaning and testing of the power cable. Compared to existing technologies, this invention allows for more convenient cable insertion during power cable testing, effectively simplifying the operation steps, reducing implementation difficulty, and thus improving testing efficiency.

Detailed Implementation

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] This invention provides, for example Figures 1-7 The power cable damage detection device shown includes a cleaning guide mechanism 1, a three-way detection mechanism 2 on the top left side of the cleaning guide mechanism 1, a rotating traction mechanism 3 in the middle of the inner cavity of the cleaning guide mechanism 1, a cable end clamping mechanism 4 on the left side of the rotating traction mechanism 3, a brushing mechanism 5 at the bottom of the inner cavity of the cleaning guide mechanism 1, and a water removal mechanism 6 on the right side of the inner cavity of the cleaning guide mechanism 1.

[0020] like Figure 2 As shown, the cleaning guide mechanism 1 includes a cleaning tank 11 with a top opening, which is filled with cleaning fluid. A limit post 12 is fixedly installed at the top rear side of the inner cavity of the cleaning tank 11. Guide concave wheels A13 are rotatably nested at the bottom, right side and top of the inner cavity of the cleaning tank 11 via pins. A cleaning fluid inlet pipe 14 and a cleaning fluid outlet pipe 15 are fixedly installed through the right side of the cleaning tank 11 from top to bottom. The cleaning fluid outlet pipe 15 is used to discharge the cleaning fluid that has reached the end of its service life, while the cleaning fluid inlet pipe 14 is used to fill the cleaning tank 11 with cleaning fluid.

[0021] like Figure 3 As shown, the three-way detection mechanism 2 includes a fixed frame 21 fixedly installed on the top left side of the cleaning tank 11. A guide wheel B26 is rotatably nested inside the fixed frame 21 via a pin. Three sets of detection components are evenly fixedly installed on the top of the guide wheel B26 inside the fixed frame 21. A power cable entry channel is formed between the three sets of detection components. Each set of detection components includes a fixed column 22 that is fixedly inserted through the fixed frame 21. An installation plate 23 is fixedly connected to the inner end of the fixed column 22. A camera 24 and multiple supplementary lights 25 are fixedly installed on the side of the installation plate 23 away from the fixed column 22. The camera 24 and the supplementary lights 25 are common knowledge in the art, so their detection principles will not be described in detail here.

[0022] By setting up the cleaning guide mechanism 1 and the three-way detection mechanism 2, after the power cable is laid out, the power cable to be tested enters the cleaning liquid filled inside the cleaning tank 11 for cleaning after being guided by the guide concave wheel B26. Then, under the guidance of the guide concave wheel A13 at the bottom of the inner cavity of the cleaning tank 11, it passes between the brushing mechanisms 5 to achieve brushing. Then, under the continued guidance of the guide concave wheel A13, the brushed power cable passes between the water removal mechanism 6 from bottom to top, and the residual cleaning liquid on its surface is scraped off. Finally, under the guidance of the two guide concave wheels A13 at the top of the inner cavity of the cleaning tank 11, the power cable passes between the cable end clamping mechanism 4 in the open state and enters between the three sets of detection components and is detected by the three sets of detection components.

[0023] like Figure 4 As shown, the rotary traction mechanism 3 includes an intermediate shaft 31 rotatably nested in the middle of the rear side of the inner cavity of the cleaning tank 11 via a ball bearing. The rear end of the intermediate shaft 31 is connected to a motor 32 fixedly installed on the back of the cleaning tank 11. A rotating disk 33, a torsion spring 34, and an end plate 35 are sequentially sleeved on the outside of the intermediate shaft 31 from back to front. The rotating disk 33 is fixedly connected to the intermediate shaft 31, and the torsion spring 34 is fixedly connected between the rotating disk 33 and the end plate 35. The end plate 35 is rotatably connected to the intermediate shaft 31 via a ball bearing. Two concentric arc-shaped clearance grooves 36 are opened on the front of the rotating disk 33. The end of any arc-shaped clearance groove 36 is connected to a traction groove 37 also opened on the front of the rotating disk 33. An outer sleeve 38 is sleeved on the outside of the torsion spring 34. The rear end of the outer sleeve 38 is fixedly connected to the rotating disk 33, and the front end of the outer sleeve 38 is rotatably nested on the back of the end plate 35 via a ball bearing. An arc-shaped push plate 39 is fixedly connected to the left side of the outer sleeve 38.

[0024] By setting up the above structure, the motor 32 drives the intermediate shaft 31 to rotate counterclockwise. The motor 32 drives the intermediate shaft 31, the outer sleeve 38 and the arc-shaped push plate 39 to rotate synchronously. At the same time, the torsion spring 34 drives the end plate 35 to rotate counterclockwise. The end plate 35 then drives the end of the power cable to be tested, which is clamped by the clamping plate A42 and the clamping plate B45, to rotate counterclockwise through the L-shaped arm 41. During this process, the end of the power cable to be tested is pulled and passes through the avoidance channel A and the avoidance channel B, and finally arrives at the upper left of the limit post 12. At this time, the power cable to be tested is wrapped around the outside of multiple guide concave wheels A13. When the end plate 35 cannot continue to rotate due to obstruction, as the rotating disk 33 continues to rotate, the rotating disk 33 stores energy in the torsion spring 34. At the same time, the rotating disk 33 drives the arc-shaped push plate 39 to push the end of the sliding shaft 43 through the outer sleeve 38.

[0025] like Figure 5 As shown, the cable end clamping mechanism 4 includes an L-shaped arm 41 fixedly connected to the left end of the back of the end plate 35. A clamping plate A42 is fixedly connected to the front end of the L-shaped arm 41. A sliding shaft 43 is slidably arranged on the inner side of the L-shaped arm 41 along the horizontal direction via a linear bearing. A pull rod 44 is fixedly connected to the left end of the sliding shaft 43. A clamping plate B45 is fixedly connected to the front end of the pull rod 44. An elastic reset member 46, which is a spring, is sleeved on the outer side of the sliding shaft 43 and fixedly connected between the L-shaped arm 41 and the pull rod 44.

[0026] By setting up the above structure, before the test begins, the end of the power cable to be tested is picked up and moved from left to right around the guide wheel B26. Then, the pull rod 44 is pulled to the left. The pull rod 44 drives the sliding shaft 43 and the clamping plate B45 away from the L-shaped arm 41. At the same time, the elastic reset member 46 is stretched. Then, the end of the power cable to be tested is inserted between the clamping plate A42 and the clamping plate B45. Then, the pull rod 44 is released. At this time, the stretched elastic reset member 46 drives the sliding shaft 43 and the clamping plate B45 to move to the right and reset through the pull rod 44. Clamping plate A42 and clamping plate B45 cooperate to clamp the end of the power cable under test. Subsequently, when the end of the power cable under test reaches the upper left of the limit post 12, as the rotating disk 33 continues to rotate, the rotating disk 33 stores energy in the torsion spring 34. At the same time, the rotating disk 33 drives the arc-shaped push plate 39 through the outer sleeve 38 to push the end of the sliding shaft 43, thereby causing the sliding shaft 43 to drive the pull rod 44 to move away from the L-shaped arm 41. The elastic reset member 46 is stretched again, and at the same time, the clamping plate B45 disengages from the top of the end of the power cable under test.

[0027] like Figure 6As shown, the washing mechanism 5 includes an upper cleaning brush 51 fixedly nested at the bottom of the front side of the inner cavity of the cleaning tank 11. A lower cleaning brush 52 is provided at the bottom of the upper cleaning brush 51. An avoidance channel A is formed between the upper cleaning brush 51 and the lower cleaning brush 52 to avoid the cable end clamping mechanism 4. The rear end of the top of the lower cleaning brush 52 is slidably provided with a guide shaft A53 fixedly connected to the inner wall of the cleaning tank 11 via a linear bearing. A traction plate A54 is fixedly connected to the rear side of the top of the lower cleaning brush 52. A traction rod A55 is fixedly provided through the top of the back of the traction plate A54. The traction rod A55 is slidably provided at the end of the adjacent arc-shaped avoidance groove 36 away from the corresponding traction groove 37.

[0028] By setting up the above structure, when the rotating disk 33 rotates counterclockwise, it drives the two arc-shaped clearance grooves 36 and the two traction grooves 37 to rotate synchronously. At this time, the traction rod A55 slides relative to each other inside the adjacent arc-shaped clearance grooves 36. As the rotating disk 33 continues to rotate, the traction rod A55 reaches the entrance position of the corresponding traction groove 37. When the rotating disk 33 continues to rotate, the traction rod A55 enters the inner side of the adjacent traction groove 37. During the process of the rotating disk 33 continuing to drive the traction groove 37 to rotate counterclockwise, the traction rod A55 is pulled upward by the adjacent traction groove 37. The traction rod A55 then drives the lower cleaning brush 52, which is guided by the guide shaft A53, to move upward through the traction plate A54. This, in turn, cooperates with the cleaning brush 51 to complete the wrapping of the power cable to be tested, making it convenient to clean the power cable in the future.

[0029] like Figure 7 As shown, the water removal mechanism 6 includes an inner scraper 61 fixedly nested in the top right side of the inner cavity of the cleaning tank 11. An outer scraper 62 is provided on the right side of the inner scraper 61. An avoidance channel B is formed between the inner scraper 61 and the outer scraper 62 to avoid the cable end clamping mechanism 4. A traction plate B63 is fixedly connected to the rear end of the top of the outer scraper 62. A guide shaft B64 is slidably provided through the left side of the traction plate B63 in the horizontal direction via a linear bearing and is fixedly connected to the inner wall of the cleaning tank 11. A traction rod B65 is fixedly provided through the left end of the back side of the traction plate B63. The traction rod B65 is slidably provided at the end of the adjacent arc-shaped avoidance groove 36 away from the corresponding traction groove 37.

[0030] By setting the above structure, when the rotating disk 33 rotates counterclockwise, it drives the two arc-shaped clearance grooves 36 and the two traction grooves 37 to rotate synchronously. At this time, the traction rod B65 slides relative to each other inside the adjacent arc-shaped clearance grooves 36. As the rotating disk 33 continues to rotate, the traction rod B65 reaches the entrance position of the corresponding traction groove 37. When the rotating disk 33 continues to rotate, the traction rod B65 enters the inner side of the adjacent traction groove 37. During the process of the rotating disk 33 continuing to drive the traction groove 37 to rotate counterclockwise, the traction rod B65 is pulled to the left by the adjacent traction groove 37. The traction rod B65 then drives the outer scraper 62 to move to the left through the traction plate B63 guided by the guide shaft B64. This allows the outer scraper 62 to cooperate with the inner scraper 61 to complete the wrapping of the power cable to be tested, making it convenient to scrape off the cleaning liquid on the surface of the power cable.

[0031] The specific working process of this invention is as follows: Take the end of the power cable to be tested and move it from left to right around the guide concave wheel B26. Then pull the lever 44 to the left. The lever 44 drives the sliding shaft 43 and the clamping plate B45 away from the L-shaped arm 41. At the same time, the elastic reset member 46 is stretched. Then insert the end of the power cable to be tested between the clamping plate A42 and the clamping plate B45. Then release the lever 44. At this time, the stretched elastic reset member 46 drives the sliding shaft 43 and the clamping plate B45 to move to the right and reset through the lever 44. The clamping plate A42 and the clamping plate B45 cooperate with each other to clamp the end of the power cable to be tested. The motor 32 drives the intermediate shaft 31 to rotate counterclockwise. The motor 32 drives the intermediate shaft 31, the outer sleeve 38 and the arc-shaped push plate 39 to rotate synchronously. At the same time, the end plate 35 is driven to rotate counterclockwise through the torsion spring 34. The end plate 35 drives the end of the power cable to be tested, which is clamped by the clamping plate A42 and the clamping plate B45, to rotate counterclockwise through the L-shaped arm 41. During this process, the end of the power cable to be tested is pulled and passes through the avoidance channel A and the avoidance channel B, and finally arrives at the upper left of the limit post 12. At this time, the power cable to be tested is wrapped around the outside of multiple guide concave wheels A13. When the rotating disk 33 rotates counterclockwise, it drives the two arc-shaped clearance grooves 36 and the two traction grooves 37 to rotate synchronously. At this time, the traction rods A55 and B65 slide relative to each other inside the adjacent arc-shaped clearance grooves 36. When the end of the power cable to be tested reaches the upper left of the limit post 12, the L-shaped arm 41 is blocked by the limit post 12. The L-shaped arm 41 and the end plate 35 cannot continue to rotate. At the same time, the traction rods A55 and B65 reach the entrance position of the corresponding traction groove 37. The rotating disk 33 continues to rotate. At this time, the rotating disk 33 stores energy in the torsion spring 34. At the same time, the rotating disk 33 drives the arc-shaped push plate 39 through the outer sleeve 38 to push the end of the sliding shaft 43, thereby causing the sliding shaft 43 to drive the pull rod 44 to move away from the L-shaped arm 41. The elastic reset member 46 is stretched again, and at the same time, the clamping plate B45 is disengaged from the top of the end of the power cable to be tested. As the rotating disk 33 continues to rotate, traction rods A55 and B65 enter the inner side of the adjacent traction groove 37. As the rotating disk 33 continues to drive the two traction grooves 37 to rotate counterclockwise, traction rod A55 is pulled upward by the adjacent traction groove 37. Traction rod A55 then drives the lower cleaning brush 52, which is guided by the guide shaft A53, to move upward through the traction plate A54. This, in turn, works with the cleaning brush 51 to complete the wrapping of the power cable to be tested. Traction rod B65 is pulled to the left by the adjacent traction groove 37. Traction rod B65 then drives the outer scraper 62 to move to the left through the traction plate B63, which is guided by the guide shaft B64. This allows the outer scraper 62 to work with the inner scraper 61 to complete the wrapping of the power cable to be tested. At this point, the motor 32 is stopped. Take the end of the power cable to be tested and let it enter between the three sets of detection components through the power cable entry channel. During this process, the bottom of the end of the power cable to be tested is separated from the clamping plate A42. Finally, connect the end of the power cable to be tested to the winding equipment and make the winding equipment continuously wind and pull the power cable to be tested. During this process, the power cable under test enters the cleaning fluid filled inside the cleaning tank 11 after being guided by the guide concave wheel B26. Then, guided by the guide concave wheel A13 at the bottom of the inner cavity of the cleaning tank 11, it passes between the upper cleaning brush 51 and the lower cleaning brush 52, thereby achieving brushing. Subsequently, under the continued guidance of the guide concave wheel A13, the brushed power cable passes between the inner scraper 61 and the outer scraper 62 from bottom to top, and the residual cleaning fluid on its surface is scraped off. Finally, guided by the two guide concave wheels A13 at the top of the inner cavity of the cleaning tank 11, the power cable passes between the open clamping plate A42 and the clamping plate B45 and enters between the three sets of detection components, where it is detected by the three sets of detection components.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
