Description

Technical Field

[0001] The invention relates to the technical field of cable withstand voltage detection, in particular to a withstand voltage detection device for a power cable. Background Art

[0002] A cable is made of one or more mutually insulated conductors and an outer insulating protective layer. It is a wire that transmits electricity or information from one place to another. It is usually a rope-like cable made up of several or several groups of wires twisted together. Each group of wires is insulated from each other and often twisted around a center. The entire outside is covered with a highly insulating covering layer. The cable has the characteristics of being powered inside and insulated outside.

[0003] The existing patent (application number: 202110382354.7) discloses a power cable pressure test detection equipment, which injects pressure test oil into the insulation chamber, and then drives the two fixing rings in the same group to move closer to or away from each other through the meshing relationship between the limit threaded rod and the fixing ring. When the two fixing rings are separated from each other, the torsion spring arranged on the rotating shaft provides resistance and enables the connecting arm to drive the adjacent clamping strips and the adjacent fixed rings to move closer to each other, while the sliding spring arranged in the connecting groove and the compression spring arranged in the clamping cylinder provide a restoring force to the device to ensure the reset of the device, thereby changing the distance between the two adjacent fixed rings, and further changing the radius of the test cable, so as to meet the test needs of cables of different models.

[0004] However, the above technical solution still has certain defects. When the device detects the cable, it first injects pressure-resistant testing oil into the insulation chamber, and then passes the cable through multiple sets of fixing mechanisms to connect with the detector for testing. However, when the cable is connected, the staff needs to manually reach into the insulation chamber to pass the cable through the multiple sets of fixing mechanisms in turn to connect with the detector, which takes too long and reduces the detection efficiency of the cable. For this reason, a pressure-resistant testing device for power cables is proposed. Summary of the invention

[0005] Based on this, an object of the present invention is to provide a withstand voltage detection device for a power cable to solve the technical problems raised in the above background.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solutions: a withstand voltage detection device for a power cable, comprising an insulation chamber, a first top plate is fixed to one side of the top of the insulation chamber, and a second top plate is fixed to one end of the top of the insulation chamber away from the first top plate, a traction assembly is provided on one side of the top of the first top plate, a clamping and moving assembly is slidably connected to the inner wall of the insulation chamber, and a conveying assembly is provided at the bottom end of the second top plate;

[0007] The traction assembly includes a shell fixedly connected to one side of the top end of the first top plate, a winding shaft is rotatably connected inside the shell, a wire rope is provided on the surface of the winding shaft, and both ends of the winding shaft are connected to the shell through a spring disk, a moving block is fixed to the bottom end of the wire rope, a circular shaft is rotatably connected inside the moving block, eight groups of vertical plates are fixedly connected to the surface of the circular shaft, L-shaped grooves matching the circular shaft are provided on both sides of the inner wall of the insulation chamber, arc-shaped rods are fixed to one side of the eight groups of vertical plates, and the surface of the arc-shaped rods slides; an arc-shaped cylinder is slidably connected, a connecting pipe is provided on one side of the arc-shaped cylinder, and one side of the moving block is provided with a connecting pipe. Eight groups of fixed blocks are welded, and the end of the connecting tube away from the arc tube is rotatably connected to the telescopic rod through the damping shaft, and the end of the telescopic rod away from the connecting tube is fixed with an arc clamping plate, one end of the circular shaft surface is rotatably connected to the belt, a moving rod is provided on the belt surface, and the end of the inner wall of the belt away from the circular shaft is rotatably connected to the rotating shaft, the moving rod, the rotating shaft and the belt are transmitted through a pulley, a connecting block is fixed to the bottom end of the inner part of the insulation chamber, a long shaft is rotatably connected to the connecting block, a movable plate is fixedly connected to the surface of the long shaft, and torsion springs are provided at both ends of the long shaft.

[0008] In summary, the present invention mainly has the following beneficial effects:

[0009] 1. The present invention enables the moving rod to drive the moving block to move along the L-shaped groove. The arc-shaped clamping plate changes from the vertical direction to the horizontal direction under the action of the movable plate until the cable passes through between the two groups of arc-shaped clamping plates. At this time, the rotating shaft is rotated to clamp and fix the cable with the arc-shaped clamping plate, and then the moving rod is reset, so that the cable is docked with the detector for detection. The traction component can make the cable pass through multiple groups of clamping and moving components in the pressure-resistant detection oil and dock with the detector, avoiding the staff from spending a lot of time on inserting and docking the cables. At the same time, because the pressure-resistant detection oil needs to be injected into the insulation chamber first during the detection, and then the cable is placed in the insulation chamber for pressure detection, it is also avoided that the staff puts their hands into the pressure-resistant detection oil for operation, and the detection efficiency of the cable is further improved by this component.

[0010] 2. The present invention inserts the cable into the square seat, and the ball bearing facilitates the cable to be better preliminarily bent in the square seat. At the same time, under the action of the arc plate and the fourth spring, the cable is squeezed to a certain extent, so that the surface of the cable can better fit the surface of the conveying wheel, which is convenient for the subsequent conveying of the cable. The conveying shaft and the conveying wheel are driven to rotate synchronously by gears and ratchet gears, and the cable is conveyed and passes through the clamping plates on the four sets of movable shafts. The conveying wheel can effectively prevent the cable from abutting and twisting when it is conveyed in a 90-degree bend, which is convenient for better conveying. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0031] The following describes an embodiment of the present invention based on its overall structure.

[0032] A withstand voltage detection device for a power cable, such as Figure 1-15 As shown, it includes an insulation chamber 100, a first top plate 110 is fixed to one side of the top of the insulation chamber 100, and a second top plate 130 is fixed to one end of the top of the insulation chamber 100 away from the first top plate 110, a traction assembly 200 is provided on one side of the top of the first top plate 110, a clamping and moving assembly 300 is slidably connected to the inner wall of the insulation chamber 100, and a conveying assembly 400 is provided at the bottom end of the second top plate 130;

[0033] The traction assembly 200 includes a shell 210 fixedly connected to one side of the top of the first top plate 110, a winding shaft 220 is rotatably connected inside the shell 210, a wire rope 230 is arranged on the surface of the winding shaft 220, and both ends of the winding shaft 220 are connected to the shell 210 through a spring disk, a moving block 240 is fixed to the bottom end of the wire rope 230, a round shaft 250 is rotatably connected inside the moving block 240, and eight groups of vertical plates 260 are fixedly connected to the surface of the round shaft 250, L-shaped grooves 251 matching the round shaft 250 are provided on both sides of the inner wall of the heat preservation chamber 100, and an arc rod 270 is fixed to one side of the eight groups of vertical plates 260. The surface of the arc rod 270 slides; the arc tube 280 is slidably connected, a connecting tube 290 is provided on one side of the arc tube 280, eight groups of fixed blocks 2910 are welded on one side of the moving block 240, and the end of the connecting tube 290 away from the arc tube 280 is rotatably connected to the telescopic rod 2920 through the damping shaft, and the end of the telescopic rod 2920 away from the connecting tube 290 is fixed with an arc splint 2930, and one end of the surface of the round shaft 250 is rotatably connected to the belt 2940, and the surface of the belt 2940 is provided with a moving rod 2950, ​​and the inner wall of the belt 2940 is rotatably connected to the rotating shaft at one end away from the round shaft 250 2960, the moving rod 2950, ​​the rotating shaft 2960 and the belt 2940 are driven by the pulley, a connecting block 2993 is fixed at the bottom of the interior of the heat preservation chamber 100, a long shaft 2994 is rotatably connected inside the connecting block 2993, a movable plate 2995 is fixedly connected to the surface of the long shaft 2994, and torsion springs 2996 are arranged at both ends of the long shaft 2994, the clamping moving assembly 300 includes four groups of moving shafts 310 slidably connected to both sides of the inner wall of the heat preservation chamber 100, a plurality of groups of slide grooves 321 are arranged inside the moving shaft 310, a slider 320 is slidably connected in the slide groove 321, and a slider 320 is slidably connected in the slide groove 321. A second spring 330 is fixed to one side of the block 320, and a supporting block 340 is fixed to the bottom end of the slider 320, a splint 350 is fixed to one side of the supporting block 340, an end of the splint 350 close to the first top plate 110 has a trumpet-shaped opening, and an end of the splint 350 close to the second top plate 130 has a conical opening, square tubes 360 are fixed to the bottom ends of both sides of the four sets of movable shafts 310, a third spring 370 is arranged inside the square tube 360, an inclined block 380 slidably connected to the square tube 360 ​​is arranged at the bottom end of the third spring 370, and an inclined groove 381 matching the inclined block 380 is opened inside the insulation chamber 100.

[0034] By injecting pressure test oil into the insulation chamber 100 for insulation, the staff moves the moving rod 2950 downward, so that the moving rod 2950 drives the moving block 240 to move synchronously through the limit block 2951 and the circular shaft 250, and pulls the rope 230 at the same time, and the moving block 240 drives the fixed block 2910 to move synchronously. When the moving block 240 moves along the L-shaped groove 251, the arc splint 2930 and the abutment block 2931 will contact with the movable plate 2995 when moving. When the arc splint 2930 and the abutment block 2931 continue to move, the movable plate 2995 abuts and fits with the abutment block 2931, which will change the arc splint 2930 from the vertical direction to the horizontal direction, and then through one side of the arc splint 2930, The arc-shaped clamping plate 2930 is inserted into the clamping plate 350 on the side close to the first top plate 110, so that the clamping plates 350 on both sides move to both sides, and at the same time, the fixed block 2910 will fit with the supporting block 340, thereby driving a group of movable shafts 310 to move, so that the movable shafts 310 squeeze the third springs 370 out of the inclined groove 381 through the inclined block 380 when moving, and the continuous movement of the movable shafts 310 will contact the second group of movable shafts 310, so that the clamping plate 350 in the first group of movable shafts 310 is inserted into the clamping plate 350 in the second group of movable shafts 310, and so on. When the second group of movable shafts 310 drives the third group of movable shafts 310 to move, the L-shaped connecting blocks 410 on the third group of movable shafts 310 will move synchronously until the four groups of movable shafts 310 are connected. All of them move to the side close to the second top plate 130, and through the pushing force on the moving shaft 310 to one side and the force transmitted to the other side by the cable 140, the two groups of forces are opposite, so that the cable 140 can better pass through the multiple groups of clamping plates 350, until the cable 140 passes between the two groups of arc-shaped clamping plates 2930, at this time, the rotating shaft 2960 is rotated, and the circular shaft 250 is driven to rotate by the belt 2940, so that the circular shaft 250 drives the vertical plate 260 to rotate synchronously, and the vertical plate 260 drives the arc rod 270 to move synchronously and squeeze the hydraulic oil inside the arc cylinder 280, so that the hydraulic oil enters the connecting pipe 290, and drives the telescopic rod 2920 and the arc clamping plate 2930 to move under the action of the oil pressure, so that the arc clamping plate 2930 clamps and fixes the cable 140, and then Then the moving rod 2950 is reset along the L-shaped groove 251, and then the cable 140 is docked with the detector 120 for detection. When the cable 140 is pulled by the arc-shaped clamping plate 2930, the moving block 240 drives the pull rope 312 to move a group of moving shafts 310. The pull ropes 312 on the four groups of moving shafts 310 can make them move synchronously with the cable 140 until the four groups of moving shafts 310 are evenly spaced in the insulation room 100, so that the cable 140 can be better limited and clamped. When the moving rod 2950 moves to the corner of the L-shaped groove 251, the moving rod 2950 is pulled upward to make the cable 140 move upward through the guide shaft 313. At the same time, the arc-shaped clamping plate 2930 will change from horizontal to vertical with the cable 140.Until it is docked with the detector 120, the traction component 200 can make the cable 140 pass through multiple groups of clamping and moving components 300 in the pressure detection oil to dock with the detector 120, avoiding the staff to spend a lot of time inserting and docking the cable 140. At the same time, because it is necessary to first inject the pressure detection oil into the insulation chamber 100 during the inspection, and then put the cable 140 into the insulation chamber 100 for pressure detection, it also avoids the staff from putting their hands into the pressure detection oil for operation. The assembly further improves the detection efficiency of the cable 140.

[0035] Please refer to Figures 1 to 3 A plug connector 131 is provided at the bottom of the first top plate 110 and the second top plate 130 , and a cable 140 is plugged into the plug connector 131 . A detector 120 is installed at the top of the first top plate 110 , and one end of the cable 140 is plugged into the detector 120 .

[0036] The cable 140 is inserted into the plug connector 131 on one side of the second top plate 130 , the cable 140 is clamped and fixed by the clamping moving assembly 300 , and finally connected to the detector 120 through the plug connector 131 of the first top plate 110 to perform a withstand voltage test on the cable 140 .

[0037] Please refer to Figures 4 to 9 A limit block 2951 is welded to the bottom end of the moving rod 2950, ​​and the moving rod 2950 is slidably connected to the first top plate 110. Limit grooves 2952 that match the limit blocks 2951 are provided on both sides of the moving block 240. The connecting block 2993 is provided with four groups, and each group is divided into two. A rubber pad is provided on one side of the arc surface of the arc splint 2930, and a plurality of groups of grooves are provided on the rubber pad. An abutment block 2931 is fixed to one side of the bottom end of the arc splint 2930. A groove 2961 is provided inside the rotating shaft 2960, and a first spring 2970 is installed in the groove 2961. A square block 2980 is fixed to one side of the first spring 2970. A turntable 2990 is fixed to the end of the square block 2980 away from the first spring 2970. A plug rod 2991 is fixed to the side of the turntable 2990 close to the moving rod 2950. A plurality of slots 2992 that match the plug rod 2991 are provided on one side of the moving rod 2950.

[0038] Through the cooperation between the limit block 2951 and the limit groove 2952, the movable block 240 can be prevented from rotating synchronously when the circular shaft 250 is rotated. By pulling the turntable 2990, the square block 2980 is driven to stretch the first spring 2970 and the insertion rod 2991 is driven to move synchronously, so that the insertion rod 2991 is disengaged from the slot 2992 to facilitate the rotation of the rotating shaft 2960. At the same time, the cooperation between the insertion rod 2991 and the slot 2992 can limit it. By opening a groove on one side of the arc-shaped clamping plate 2930, the friction with the surface of the cable 140 can be better enhanced, so that the cable 140 can be better fixed.

[0039] Please refer to Figure 2 , Figures 10 to 15 , moving grooves 311 that match the moving shaft 310 are opened on both sides of the inner wall of the insulation chamber 100, and there are four groups of inclined blocks 380 and inclined grooves 381, and the width of each group of inclined blocks 380 and inclined grooves 381 decreases from the side close to the first top plate 110 to the side of the second top plate 130. The four groups of moving shafts 310 are fixedly connected to the moving blocks 240 by pull ropes 312, and a guide shaft 313 for the power cable 140 to be horizontally and vertically upward is fixed on the surface of the moving shaft 310 close to the first top plate 110.

[0040] Through the cooperation between the inclined block 380 and the inclined groove 381, the movable shaft 310 can be effectively limited and fixed. By setting the pull rope 312, it is convenient to pull multiple groups of movable shafts 310. Arranging the sizes of the inclined blocks 380 and the inclined grooves 381 from large to small can ensure that each group of movable shafts 310 corresponds to the matching inclined grooves 381 in sequence when resetting.

[0041] Please refer to Fig.13 and Fig.14 The conveying assembly 400 includes an L-shaped connecting block 410 fixedly connected to one side of a group of moving shafts 310, a conveying belt 420 is fixed to the bottom end of the L-shaped connecting block 410, and rotating rollers 430 are rotatably connected to both sides of the inner wall of the conveying belt 420, a gear 440 is fixed to the surface of a group of rotating rollers 430, and a ratchet gear 450 meshing with each other is provided on one side of the gear 440, a conveying shaft 460 is fixedly connected to the center of the ratchet gear 450, and four groups of conveying wheels 480 are fixed to the surface of the conveying shaft 460, a square seat 470 is fixed to the side of the inner wall of the insulation chamber 100 away from the first top plate 110, the conveying shaft 460 is rotatably connected to the square seat 470, and an arc plate 490 is provided on one side of the four groups of conveying wheels 480, and a base rod 491 is rotatably connected to the upper end of the inner part of the arc plate 490, and a plurality of groups of balls 4910 are rotatably connected to the side of the arc plate 490 close to the conveying wheel 480, and a fourth spring 4920 is provided on the side of the arc plate 490 away from the ball 4910.

[0042] The staff inserts the cable 140 from the plug connector 131 of the second top plate 130 into the square seat 470, and uses the ball 4910 to facilitate the cable 140 to be better preliminarily bent in the square seat 470. At the same time, under the action of the arc plate 490 and the fourth spring 4920, the cable 140 is squeezed to a certain extent, so that the surface of the cable 140 can better fit the surface of the conveying wheel 480, which is convenient for the subsequent conveying of the cable 140. When the four groups of movable shafts 310 move, the L-shaped connecting block 410 at the end of one group of movable shafts 310 will be driven to move synchronously, so that the L-shaped connecting block 410 The block 410 drives the conveyor belt 420 to move, and the conveyor belt 420 drives the rotating rollers 430 on both sides to rotate, and the rotating rollers 430 drive the gears 440 to rotate, so that the gears 440 drive the ratchet gear 450 to rotate synchronously, and the ratchet gear 450 drives the conveyor shaft 460 and the conveyor wheel 480 to rotate synchronously, and the belt conveys the cable 140 through the conveyor wheel 480 and passes through the clamping plates 350 on the four sets of movable shafts 310. The conveyor wheel 480 can effectively prevent the cable 140 from abutting and twisting when it is conveyed in a 90-degree bend, so as to facilitate better transportation.

[0043] When in use, the pressure test oil is injected into the insulation chamber 100 for insulation. The staff inserts the cable 140 into the square seat 470, and the ball 4910 facilitates the cable 140 to be better preliminarily bent in the square seat 470. At the same time, under the action of the arc plate 490 and the fourth spring 4920, the cable 140 is squeezed to a certain extent, so that the surface of the cable 140 can better fit the surface of the conveying wheel 480, which is convenient for the subsequent conveying of the cable 140. When the moving block 240 drives the arc clamping plate 2930 and the abutting block 2931 to contact the movable plate 2995 when moving, The movable plate 2995 abuts against the abutment block 2931, which changes the arc-shaped clamping plate 2930 from the vertical direction to the horizontal direction. Then, through one side of the arc-shaped clamping plate 2930, the arc-shaped clamping plate 2930 is inserted into the clamping plate 350 close to the first top plate 110, so that the clamping plates 350 on both sides move to both sides. At the same time, the fixed block 2910 abuts against the support block 340, thereby driving a group of movable shafts 310 to move, so that the movable shaft 310 squeezes the third spring 370 out of the inclined groove 381 through the inclined block 380 when moving. The continuous movement of the movable shaft 310 contacts the second group of movable shafts 310. The clamping plate 350 in the first group of movable shafts 310 is inserted into the clamping plate 350 in the second group of movable shafts 310, and so on, until the cable 140 passes through the two groups of arc clamping plates 2930, so that the traction component 200 can clamp and pull the cable 140, and the gear 440 and the ratchet gear 450 drive the conveying shaft 460 and the conveying wheel 480 to rotate synchronously, so that the cable 140 is conveyed and passes through the clamping plates 350 on the four groups of movable shafts 310. The conveying wheel 480 can effectively prevent the cable 140 from being abutted and twisted when being conveyed in a 90-degree bend, so as to facilitate better conveying. Through the traction component 200, the cable 140 can pass through multiple groups of clamping and moving components 300 in the pressure testing oil and dock with the detector 120, avoiding the staff from spending a lot of time on inserting and docking the cable 140. At the same time, because it is necessary to first inject the pressure testing oil into the insulation chamber 100 during the test, and then put the cable 140 into the insulation chamber 100 for pressure testing, it also avoids the staff from putting their hands into the pressure testing oil for operation. The detection efficiency of the cable 140 is further improved through this component. The parts not involved in the device are the same as the prior art or can be implemented by the prior art.
