Description

Technical Field

[0001] The present invention relates to the technical field of cable accessory detection, and in particular to a cable accessory fault detection method and system. Background Art

[0002] Overhead lines are currently the most important power equipment for long-distance transmission of electric energy. They have the characteristics of high voltage level and large current. Connecting hardware is an important part of overhead lines. Its quality directly affects whether the transmission lines can work normally and whether the power grid can operate safely and reliably. Strain clamps are hardware that fix the conductors, bear the conductor tension, and hang the conductors on the tension string group or tower. Once an accident occurs, it will directly cause the conductors to fall off and the line to stop operating, causing great economic losses to the power grid company and serious social impact. Therefore, the crimping quality inspection of the tension clamps is very important.

[0003] In a Chinese patent application with publication number CN112432960B, an X-ray detection device for overhead line tension clamps is disclosed, including an X-ray source, a detector and a bracket. The X-ray source and the detector are respectively arranged at two ends of the bracket. The X-ray source irradiates X-rays onto the detector. The tension clamp to be detected is in the X-ray irradiation area of ​​the detector surface. Pulleys are provided on both sides of the detector for the detection device to slide on the line.

[0004] During use of the above-mentioned X-ray detection source, a part of the wire clamps are installed in a plane on the cable surface of the high-voltage rack. When inspecting the wire clamps without obstacles above, the frame can be placed directly on the cable surface, and then the detection piece can be used to directly perform flaw detection on this type of wire clamps. Another part of the wire clamps are installed inside the gasket mounting holes of the high-voltage rack by bolts and nuts. At this time, there are obstacles above the wire clamps, and the frame cannot be placed on the wire clamp surface for inspection. Therefore, the staff is required to stand on the cable of the high-voltage rack, and then hold the frame and rotate its angle for inspection. The staff standing on the cable will produce uneven force, which will cause the frame to shake, making the inspection result of the inspection piece blurred, which can easily reduce the inspection efficiency of the inspection piece.

[0030] like Figure 1-Figure 8 As shown, a cable accessory fault inspection system includes a control terminal, a lifting device and an X-ray detection mechanism, the control terminal includes a first control module and a second control module, the first control module is used to control the lifting device to transfer the X-ray detection mechanism, and the second control module is used to control the X-ray detection mechanism to perform flaw detection on the wire clamp; The lifting device drives the X-ray detection mechanism to the high-voltage cable rack through the insulating rope, and the X-ray detection mechanism performs flaw detection on the wire clamp; X-ray inspection agencies include: An outer frame 10 and a detection member 11, wherein the detection member 11 is located inside the outer frame 10; The outer frame 10 is in an inverted L shape, one side of the outer frame 10 has a side opening, the top of the outer frame 10 has a top opening connected to the side opening, and a plurality of mounting handles are installed on the top of the outer frame 10. The insulating rope can be bound to the outer frame 10 through the mounting handles, so that the lifting device can move the outer frame 10 to the cable of the high-voltage rack through the insulating rope and the mounting handles. The front of the outer frame 10 has an arc-shaped guide plate for guiding the outer frame 10 to the cable, so that the detection member 11 can detect the wire clamp; An X-ray detection source is installed at the bottom of the detection member 11 for performing flaw detection on the wire clamp, thereby facilitating detection of the use condition inside the wire clamp, and a detector is installed at the top of the detection member 11; Two connecting frames 12 are arranged inside the detection member 11, and the two connecting frames 12 are symmetrical with the outer frame 10 as the center. The bottom of the connecting frame 12 has a first end and a second end lower than the first end, and the bottom horizontal plane of the first end is flush with the bottom horizontal plane of the arc-shaped guide plate, a sliding mouth is formed between the first end and the second end, and the sliding mouth is connected to the inner cavity of the connecting frame 12, and the bottom edge of the sliding mouth has an arc surface, and the interior of the connecting frame 12 has a linkage member 13, which is composed of an upper concave block and a lower concave block, and the inner concave surfaces of the upper concave block and the lower concave block correspond to each other, and there is a gap between the upper concave block and the lower concave block, and the inner walls of the upper concave block and the lower concave block are both installed with limiting wheels, and the limiting wheels have inner concave surfaces, and the inner concave surfaces are arc-shaped, and the inner concave surface at the lower end of the upper concave block and the inner concave surface at the upper end of the lower concave block can form a circle, so as to facilitate the clamping of the cable and maintain the stability of the outer frame 10.

[0031] The X-ray detection source and detector belong to the prior art and will not be described again. In the present embodiment, the lifting device is a drone. Since the horizontal plane of the inner concave surface axis of the upper concave block corresponds to the detection direction of the X-ray detection source, when the cable on the high-voltage rack is to be inspected, the insulating rope is first passed through the installation handle and then installed on the bottom of the drone. The drone is turned on for liftoff. The drone drives the outer frame 10 to move to the cable of the high-voltage rack through the insulating rope, so that the arc-shaped guide plate on the outer frame 10 is against the cable. Then the drone drives the outer frame 10 to slide left or right, so that the corresponding cable slides into the interior of the outer frame 10, and the cable is introduced into the sliding mouth through the arc-shaped guide plate. At this time, the drone is moved down, the overall weight of the outer frame 10 and the detection member 11 will move down, and the cable will move up and slide to the top of the sliding mouth, and at the same time, the lower concave block will move up and slide to the upper concave block. At this time, the lower concave block cooperates with the upper concave block to clamp and limit the cable, and the X-ray detection source can detect the wire clamp on the cable, and the detection result will be transmitted to the display on the ground for display.

[0032] When the hanging wire clamp hung on the pole tower is inspected, the inspection member 11 can rotate, and the front end of the top of the inspection member 11 will slide out of the top opening, and then part of the inspection member 11 slides out of the outer frame 10, and the X-ray detection source also slides out of the outer frame 10. At this time, the connection frame 12 on the side away from the inspection member 11 slides in the opposite direction to the inspection member 11, thereby maintaining the torque balance of the outer frame 10 and the inspection member 11, and the inspection member 11 is in an inclined state, so that the X-ray detection source can inspect the hanging wire clamp hung on the pole tower, and the inspection result is also transmitted to the display on the ground for display, so that the staff can know the display situation inside the wire clamp.

[0033] refer to Figure 1-Figure 6 As shown, a driving assembly 20 is installed on the outer frame 10 for controlling the sliding and rotating state of the detection member 11, so as to facilitate the detection of the suspension clamp suspended on the pole tower.

[0034] The driving assembly 20 includes a limit shaft 21 arranged inside the detection member 11. The limit shaft 21 can drive the detection member 11 to slide and rotate, so as to facilitate the X-ray detection source to detect the suspension wire clamp suspended on the pole tower. The outer surface of the limit shaft 21 is rotatably connected with a positioning ring 22, which is used to limit the limit shaft 21, so as to maintain the stability of the limit shaft 21 during rotation. A connecting arm 23 is fixed between the outer surface of the positioning ring 22 and the inner wall of the detection member 11, which is used to support the positioning ring 22, so as to maintain the stability of the limit shaft 21.

[0035] The limiting shaft 21 is provided with a first limiting member 24 which can drive the limiting shaft 21 to rotate, thereby driving the detection member 11 to rotate and adjust the angle to detect the suspension wire clamp suspended on the pole tower.

[0036] The first limiting member 24 includes a cylinder 240 arranged outside the limiting shaft 21, and the maximum diameter value of the inner cavity of the cylinder 240 is greater than the minimum diameter value of the limiting shaft 21, and the limiting shaft 21 is slidably connected to the inside of the cylinder 240, and a plurality of limiting blocks 241 arranged in a ring are fixed to the outer surface of the limiting shaft 21, and the distances between the plurality of limiting blocks 241 are equal, and a plurality of limiting grooves 242 arranged in a ring are opened on the inner wall of the cylinder 240, and the distances between the plurality of limiting grooves 242 are equal, and the number of the limiting grooves 242 is the same as that of the limiting blocks 241, and the limiting blocks 241 are slidably connected to the inside of the limiting grooves 242, and when the cylinder 240 rotates around its axial direction, the cooperation of the limiting blocks 241 and the limiting grooves 242 can drive the detection member 11 to rotate, and the detection angle of the detection member 11 can be adjusted.

[0037] A mounting bracket 25 is fixed to the inner top wall of the outer frame 10, a driving source 26 is installed on the inner bottom wall of the mounting bracket 25, and the output end of the driving source 26 is fixed on one end of the cylinder 240. When the output end of the driving source 26 drives the cylinder 240 to rotate, the limiting shaft 21 can be driven to rotate through the limiting block 241 and the limiting groove 242, so that the detection line clamp angle of the detection member 11 can be adjusted.

[0038] A second limiting member 27 is provided on the connecting frame 12 for supporting the detecting member 11 , thereby maintaining the stability of the detecting member 11 when in use.

[0039] The second limiting member 27 includes an arc-shaped bar 270 fixed between the two connecting arms 23, a limiting slider 271 is provided on the arc-shaped bar 270, a receiving slide opening is opened on the limiting slider 271, and the limiting slider 271 is slidably connected inside the receiving slide opening, a slide rail 272 is fixed to the inner wall of the outer frame 10, and the arc-shaped bar 270 is slidably connected inside the receiving slide opening, and the arc-shaped bar 270 cooperates with the limiting slider 271 and the slide rail 272 to support the detection member 11, thereby maintaining the stability of the detection member 11 when sliding and rotating.

[0040] A pusher 28 is provided on the connecting arm 23 for adjusting the position of the detection member 11 , so that the detection member 11 can slide out of the outer frame 10 to detect the suspension clamp suspended on the pole tower.

[0041] The pushing member 28 includes two side plates 280 fixed on the outer wall of the positioning ring 22, and the two side plates 280 are symmetrical with the positioning ring 22 as the center. A U-shaped frame 282 is arranged on the side of the side plate 280 away from the positioning ring 22, and a connecting column 281 is fixed between the U-shaped frame 282 and the side plate 280. The inner wall of the U-shaped frame 282 is rotatably connected with a roller 283. A concave cylinder 286 is fixed on the outer wall of the cylinder 240, and the notch of the concave cylinder 286 faces the positioning ring 22. The inner wall of the concave cylinder 286 is slidably connected with a linkage plate 285, and the linkage plate 285 has a slope. When the roller 283 rolls to the slope of the linkage plate 285, the positioning ring 22 can be pushed through the connecting column 281 and the U-shaped frame 282, so that the X-ray detection machine on the detection member 11 slides out of the outer frame 10 to detect the suspension wire clamp suspended on the pole tower.

[0042] Two top plates are fixed to the inner wall of the arc-shaped guide plate, and the two top plates are respectively located on the upper sides of the corresponding connecting frames 12, and the two connecting frames 12 are connected to the bottoms of the corresponding top plates. The outer wall of the concave cylinder 286 is rotatably connected with a first limiting ring 287, and the top of the first limiting ring 287 is fixed to the bottom of the corresponding top plate, and the first limiting ring 287 is used to support the concave cylinder 286, thereby maintaining the stability of the concave cylinder 286, and the outer surface of the linkage plate 285 is fixed with a second limiting ring 288, and the top of the second limiting ring 288 is fixed to the bottom of the corresponding top plate, and the second limiting ring 288 is used to support the linkage plate 285, thereby maintaining the stability of the linkage plate 285.

[0043] The display device on the ground can control the opening and closing states of the drone, the X-ray detection source and the driving source 26 through the control system. Since the initial position of the roller 283 is spaced from the linkage plate 285 and the roller 283 is located at the bottom end of the linkage plate 285, when the X-ray detection source detects the suspension wire clamp suspended on the pole tower, the output end of the driving source 26 drives the cylinder 240 to rotate, and the cylinder 240 drives the concave cylinder 286 to rotate around its axial direction. At this time, the cylinder 240 drives the limiting shaft 21 to rotate around its axial direction through the limiting block 241 and the limiting groove 242, and the limiting shaft 21 drives the detection part 11 to rotate clockwise through the positioning ring 22 and the connecting arm 23. The direction of rotation is from the driving source 26 to the detection part 11, and the arc strip 270 slides inside the accommodating sliding mouth of the limiting slider 271.

[0044] As the cylinder 240 and the limit shaft 21 rotate, the roller 283 will move to the bottom end of the slope of the linkage plate 285, and the detection member 11 is now away from the top of the cable and is in an inclined state. When the roller 283 slides from the bottom end of the slope to its top, the roller 283 is pushed by the linkage plate 285, and the roller 283 cooperates with the U-shaped frame 282, the connecting column 281 and the side plate 280 to enable the limit shaft 21 and the positioning ring 22 to drive the detection member 11 to slide out of the side opening of the outer frame 10. At the same time, the limit slider 271 slides inside the slide rail 272, so that the position and angle of the detection member 11 can be adjusted, and the wire clamp without any obstruction above and the suspension wire clamp bolted on the pole tower can be detected, thereby preventing the outer frame 10 from being placed on the suspension wire clamp hanging on the pole tower for detection.

[0045] refer to Figure 3 , Figure 4 , Figure 5 , Figure 7 and Figure 8 As shown, a limit assembly 30 is provided on the outer frame 10 for adjusting the position of the connecting frame 12 so as to maintain the balance of the outer frame 10 on the cable.

[0046] The limiting assembly 30 includes an arc-shaped push strip 32 fixed on the outer surface of the concave cylinder 286, and a side block 31 is fixed on the back of the connecting frame 12 close to the concave cylinder 286, and the edge of the side block 31 has an arc-shaped surface. When the concave cylinder 286 rotates, the arc-shaped push strip 32 pushes the connecting frame 12 connected to it to slide to the side away from the detection member 11 through the side block 31, thereby maintaining the gripping force of the linkage member 13 on the cable.

[0047] A pressing member 33 is disposed inside each of the two connection frames 12 to maintain the clamping strength of the linkage member 13 on the cable.

[0048] The pressing member 33 includes a mouth-shaped frame 330 slidably connected to the inner wall of the connecting frame 12, two arc-shaped plates 331 are fixed to the bottom of the mouth-shaped frame 330, and the top of the arc-shaped plate 331 is higher than its bottom, and the arc-shaped plate 331 is in an arc section from the top to the bottom, and the top of the arc-shaped plate 331 corresponds to the bottom of the arc guide plate, and a support arm 333 is fixed between the bottom of the mouth-shaped frame 330 and the back of the lower concave block, and the support arm 333 is used to support the lower concave block to maintain the stability of the lower concave block when sliding, and a first reset spring 332 is fixed between the top of the mouth-shaped frame 330 and the inner top wall of the connecting frame 12 to support the mouth-shaped frame 330, so as to facilitate the reset of the mouth-shaped frame 330.

[0049] A reset member 34 is provided at the top of the connection frame 12 near the concave cylinder 286 for limiting the position of the connected connection frames 12, thereby facilitating the reset of the connection frames 12.

[0050] The reset member 34 includes a sliding block 340 fixed on the top of the connecting frame 12, and two symmetrical concave frames 341 are fixed on the bottom of the top plate corresponding to the sliding block 340, and the grooves of the two concave frames 341 correspond to each other, and the inner wall of the concave frame 341 is slidably connected with a slider, and one side of the slider is fixed on the side wall of the sliding block 340, and a second reset spring 342 is fixed between the inner wall of the concave frame 341 and the slider, which is used to support the sliding block 340, so as to facilitate the sliding block 340 to reset.

[0051] When the cable is introduced into the sliding opening of the connecting frame 12 and the outer frame 10 and the detection member 11 move downward as a whole, the cable moves upward against the arc plate 331, and the mouth frame 330 compresses the first return spring 332. At the same time, the mouth frame 330 drives the connected lower concave block to move upward through the support arm 333. When the mouth frame 330 moves up to be flush with the top of the corresponding upper concave block, the upper surface of the cable will press against the inner concave surface of the upper concave block, and the lower concave block will fit with the upper concave block. At this time, the inner concave surface of the upper concave block and the inner concave surface of the lower concave block form a circle to clamp and limit the cable.

[0052] Since the head end of the arc-shaped push bar 32 is close to the second limit ring 288, and the tail end of the arc-shaped push bar 32 is away from the second limit ring 288, and the initial position of the side block 31 is located at the head end of the arc-shaped push bar 32, when the concave cylinder 286 rotates counterclockwise, the arc-shaped push bar 32 presses against the side block 31 and drives the side block 31 to slide to the side away from the detection member 11, and the slider of the sliding block 340 slides inside the concave frame 341 and compresses the second return spring 342. At this time, the distance that the detection member 11 slides out of the side opening is the same as the distance that the connecting frame 12 slides, thereby maintaining the stability of the detection member 11 and the outer frame 10. When the output end of the driving source 26 drives the concave cylinder 286 to reset, the second return spring 342 drives the connected connecting frame 12 to reset through the slider and the sliding block 340.

[0053] The present invention also provides a cable accessory fault inspection method, comprising the following steps: Step 1: The lifting device is tied to the outer frame 10 through an insulating rope, and the control terminal controls the lifting device to drive the outer frame 10 to be lifted to the high-voltage rack cable for support and installation; Step 2: The control terminal controls the driving component 20 to drive the detection member 11 to rotate and slide out of the side opening of the detection member 11. At the same time, the driving component 20 can drive the connecting frame 12 and the linkage member 13 to slide away from the side opening, so that the wire clamp can be detected and the balance stability of the outer frame 10 on the cable can be maintained; Step 3: The test result of the test piece 11 is transmitted to the control terminal on the ground for display; Step 4: After the detection is completed, the control terminal controls the driving assembly 20 to drive the detection member 11 and the connecting frame 12 to restore to the initial state, and then the control terminal controls the lifting device to drive the outer frame 10 to fall to the ground.
