Technical Field

[0001] The present invention relates to the technical field of power maintenance, and specifically provides a live detection device for power maintenance. Background Art

[0002] Power maintenance mainly includes the following maintenance parts: power generation part, power supply part, substation part and distribution part, and each part is responsible by specialized personnel. It is mainly responsible for daily equipment installation and maintenance, troubleshooting, line patrol and inspection, etc. It is a profession that maintains and repairs the power grid and its affiliated equipment, with high professional requirements and certain risks.

[0003] A live detection device for power maintenance with the publication number CN214622758U relates to the technical field of live detection, including a detector. A housing is fixed on the top of the detector, and a spring telescopic rod is fixed on the bottom of the detector. Threaded rods are rotatably arranged on both sides of the inner wall of the housing. Transmission rods are threadedly connected to the outside of the two threaded rods. A clamping and cleaning assembly is arranged on the top of the transmission rod, and transmission gears are rotatably arranged inside the two transmission rods. In the above application, by arranging a clamping and cleaning assembly inside the housing, and then through the cooperation of the fixed half-ring and the transmission rod, the wire is clamped, thus avoiding the situation in traditional detection where the detection personnel need to hold the detection head with one hand and operate the detector with the other hand, facilitating the detection personnel to carry out power maintenance, reducing the operation difficulty of the detection personnel, and reducing the work intensity of the detection personnel.

[0004] However, when the above-mentioned live detection device for power maintenance is in use, although the surface of the cable is cleaned and clamped by arranging a clamping and cleaning assembly, when detecting the end of the cable, aging and other phenomena may occur due to the long-term exposure of the cable end outside, resulting in inaccurate detection results when detecting the cable end. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the present invention provides a live detection device for power maintenance, which solves the problems raised in the above background art.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: An on-line detection device for power maintenance, including a main body, the upper end of the main body is fixedly connected to the lower end of a probe, a detection port is opened at the upper end of the main body, a shearing device for shearing the wire before detection to improve the detection accuracy is provided at the upper end of the main body, a clamping and protection device is provided at the upper end of the main body, and a knocking device for knocking off the remaining wire slag after shearing is provided at the upper end of the main body; wherein, the shearing device includes a cylinder, a platform, a guillotine, a long rod, a compression spring, a connecting frame, a push rod, a large rotating shaft, a V-shaped lever and a cushion rod; the outer side of the main body is fixedly connected to the inner side of the cylinder, the output end of the cylinder is fixedly connected to the outer side of the platform, and under the push of the cylinder, the cylinder pushes the platform to move forward.

[0007] According to the above technical solution, the output end of the cylinder is fixedly connected to the outer side of the guillotine. When the platform moves, the guillotine moves forward to shear the wire. The inner wall of the main body is slidably connected to the outer wall of the long rod, and the long rod penetrates the main body. The inner side of the main body is fixedly connected to the outer side of the compression spring. When the platform moves forward, the compression spring loses extrusion and releases, pushing out the long rod. The inner side of the long rod is fixedly connected to the outer side of the connecting frame. When the long rod is pushed forward, it pushes the connecting frame to slide forward on the outer wall of the platform. The inner side of the connecting frame is fixedly connected to the outer side of the push rod. When the connecting frame slides forward, the push rod moves forward.

[0008] According to the above technical solution, the inner side of the main body is rotatably connected to the outer side of the large rotating shaft, the outer wall of the large rotating shaft is rotatably connected to the inner wall of the V-shaped lever. When the push rod moves forward, it squeezes one end of the V-shaped lever, causing it to rotate around the large rotating shaft, and the other end of the V-shaped lever is lifted. The inner side of the V-shaped lever is fixedly connected to the outer side of the cushion rod. When the other end of the V-shaped lever is lifted, the cushion rod moves forward to hold the wire.

The upper end of the main body is rotatably connected to the lower end of the short rod.

[0010] According to the above technical solution, the upper end of the main body is fixedly connected to one end of the first torsion spring, the other end of the first torsion spring is fixedly connected to the lower end of the rotating rod, and the upper end of the short rod is fixedly connected to the lower end of the rotating rod. When the connecting rod moves forward and hits one end of the rotating rod, causing the rotating rod to rotate around the short rod, the outer wall of the rotating rod is rotatably connected to the inner wall of the rotating rod, the outer wall of the rotating rod is rotatably connected to the inner wall of the L-shaped rod, and the lower end of the L-shaped rod is slidably connected to the upper end of the main body. When the rotating rod rotates, it drives one end of the rotating rod to move. At this time, the other end of the rotating rod drives the L-shaped rod to slide on the upper end of the main body. The inner side of the L-shaped rod is fixedly connected to the outer side of the clamping piece. When the L-shaped rod slides on the upper end of the main body, it drives the clamping piece to move synchronously to clamp the wire.

[0011] According to the above technical solution, the lower end of the connecting frame is fixedly connected to the upper end of the transmission rod. The outer side of the platform is rotatably connected to the inner side of the rotating block. When the platform slides forward and drives the rotating block to move forward, the rotating block collides with the transmission rod and rotates. The outer wall of the rotating block is fixedly connected to the inner wall of the protective frame. When the transmission rod rotates, it drives the protective frame to rotate synchronously. The outer side of the platform is fixedly connected to one end of the torsion spring, and the other end of the torsion spring is fixedly connected to the inner side of the protective frame. When the rotating block loses the extrusion of the transmission rod, it quickly resets under the action of the second torsion spring, driving the protective frame to rotate synchronously to protect the guillotine.

[0012] According to the above technical solution, the knocking device includes a U-shaped rod, an L-shaped hole, a pressing block, a slider, a return spring, a connecting block, a small rotating shaft, a knocking rod and a third torsion spring. The inner side of the transmission rod is fixedly connected to the outer side of the U-shaped rod. After the platform moves forward, the U-shaped rod gradually approaches the platform. An L-shaped hole is opened on the platform, and the U-shaped rod can pass through the L-shaped hole. The upper end of the U-shaped rod is fixedly connected to the lower end of the pressing block.

After the pressing block collides with the slider, the slider presses the return spring. The inner side of the platform is fixedly connected to the outer side of the connecting block. The lower end of the connecting block is fixedly connected to the upper end of the small rotating shaft. The outer wall of the small rotating shaft is rotatably connected to the inner wall of the knocking rod. When the slider presses the return spring, the slider hits one end of the knocking rod, causing the knocking rod to rotate around the small rotating shaft and the other end of the knocking rod to hit the guillotine. One end of the third torsion spring is fixedly connected to the lower end of the connecting block, and the other end of the third torsion spring is fixedly connected to the upper end of the knocking rod. When the knocking rod loses the extrusion, it rotates and resets around the connecting block under the action of the torsion spring.

[0014] The present invention provides a live detection device for power maintenance, having the following beneficial effects:

[0015] 1. By setting a shearing device in the present invention, the detected wire is placed into the device through the detection port. At this time, under the push of the cylinder, the platform moves, driving the guillotine to cut the wire, capable of cutting off the aged cable at the end of the cable, enabling more accurate detection of the wire condition through the probe later, and solving the problem that traditional live detection equipment cannot handle aged cables; when the platform moves, the connecting frame loses extrusion, and through the cooperation of the compression spring and the long rod, the connecting frame is pushed out, and through the cooperation of the push rod and the large rotating shaft, the V-shaped lever pushes out the cushion rod to be placed opposite the guillotine, making the cutting of the guillotine more convenient and the cut of the wire more flat, thereby reducing interference and improving the detection accuracy, and solving the problem that the guillotine has no support during shearing and the shearing is not flat enough.

[0016] 2. By setting a clamping and protecting device in the present invention, when the connecting rod moves, the connecting rod squeezes the rotating rod, causing the rotating rod to rotate, and through the cooperation of the short rod and the rotating rod, the L-shaped rod slides on the surface of the main body, driving the clamping piece to be below the cut of the guillotine to tighten the wire, aiming at the situation where the force of the bundled wires is dispersed, preventing the guillotine from failing to cut off in one stroke due to the dispersed force on the wire; when the platform moves, the rotating block moves away from the transmission rod, squeezing the rotating block to rotate, opening or closing the protection frame, so that when the guillotine is in use, the protection frame does not affect the guillotine, and when not in use, the guillotine is protected, solving the problem of accidental injury when the guillotine is not in use.

[0017] 3. By setting a knocking device in the present invention, when the U-shaped rod moves, it drives the extrusion block to pass through the L hole, causing the slider to slide on the main body and strike the knocking rod. Through the cooperation of the connecting block and the small rotating shaft, the knocking rod knocks the guillotine. Conversely, the U-shaped rod drives the extrusion block to pass through the L hole and return to its original position, squeezing the slider again, causing the knocking rod to knock the guillotine for the second time, making the slag remaining on the guillotine after cutting the wire fall off, solving the problem that the extrusion of the residue affects the flatness of the wire cut, thereby affecting the detection accuracy.

Specific embodiments

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0026] Please refer to Figures 1 - 6 , an embodiment of the present invention is: a live detection device for power maintenance, including a main body 1, the upper end of the main body 1 is fixedly connected to the lower end of the probe 2, a detection port 3 is opened at the upper end of the main body 1, and a shearing device 4 for shearing the wire before detection to improve the detection accuracy is arranged at the upper end of the main body 1.

[0027] Among them, the shearing device 4 includes a cylinder 401; a platform 402; a guillotine 403; a long rod 404; a compression spring 405; a connecting frame 406; a push rod 407; a large rotating shaft 408; a V-shaped lever 409 and a cushion rod 410; the outer side of the main body 1 is fixedly connected to the inner side of the cylinder 401, the output end of the cylinder 401 is fixedly connected to the outer side of the platform 402, and under the push of the cylinder 401, the cylinder 401 pushes the platform 402 to move forward. The output end of the cylinder 401 is fixedly connected to the outer side of the guillotine 403. When the platform 402 moves, the guillotine 403 moves forward to cut the wire. The inner wall of the main body 1 is slidably connected to the outer wall of the long rod 404, and the long rod 404 penetrates through the main body 1. The inner side of the main body 1 is fixedly connected to the outer side of the compression spring 405. When the platform 402 moves forward, the compression spring 405 loses extrusion and releases, pushing out the long rod 404. The inner side of the long rod 404 is fixedly connected to the outer side of the connecting frame 406. When the long rod 404 is pushed forward, it pushes the connecting frame 406 to slide forward on the outer wall of the platform 402. The inner side of the connecting frame 406 is fixedly connected to the outer side of the push rod 407. When the connecting frame 406 slides forward, the push rod 407 moves forward. The inner side of the main body 1 is rotatably connected to the outer side of the large rotating shaft 408, and the outer wall of the large rotating shaft 408 is rotatably connected to the inner wall of the V-shaped lever 409. When the push rod 407 moves forward, it squeezes one end of the V-shaped lever 409, causing it to rotate around the large rotating shaft 408, and the other end of the V-shaped lever 409 is lifted. The inner side of the V-shaped lever 409 is fixedly connected to the outer side of the cushion rod 410. When the other end of the V-shaped lever 409 is lifted, the cushion rod 410 moves forward to hold the wire against it.

[0028] In the present invention, by providing the shearing device 4, the detected wire is placed into the device through the detection port 3. At this time, under the push of the cylinder 401, the platform 402 moves, driving the guillotine 403 to cut the wire, removing the aged and contaminated positions at the end of the wire, so that the probe 2 can more accurately detect the condition of the wire later.

[0029] In the present invention, by providing the shearing device 4, when the device moves the platform 402, the connecting frame 406 loses extrusion, and through the cooperation of the compression spring 405 and the long rod 404, the connecting frame 406 is pushed out, and through the cooperation of the push rod 407 and the large rotating shaft 408, the V-shaped lever 409 pushes out the cushion rod 410 to be placed opposite to the guillotine 403, making the cutting by the guillotine 403 more convenient and the cut of the wire smoother, thereby reducing interference and improving the accuracy of detection.

[0030] When the device is working, the cylinder 401 is started. Under the push of the cylinder 401, the cylinder 401 pushes the platform 402 forward. When the platform 402 moves, the guillotine 403 moves forward to cut the wire. When the platform 402 moves forward, the compression spring 405 loses compression and releases, pushing out the long rod 404. When the long rod 404 is pushed forward, it pushes the connecting frame 406 to slide forward on the outer wall of the platform 402. When the connecting frame 406 slides forward, the push rod 407 moves forward. When the push rod 407 moves forward, it squeezes one end of the V-shaped lever 409, causing it to rotate around the large rotating shaft 408, and the other end of the V-shaped lever 409 is lifted. When the other end of the V-shaped lever 409 is lifted, the cushion rod 410 moves forward to hold the wire. Conversely, when the cutting is completed, the cylinder 401 retracts, driving the platform 402 to move backward. When the platform 402 moves backward, it squeezes the connecting frame 406 to move backward. When the connecting frame 406 moves backward, it squeezes the long rod 404 and the compression spring 405 to move backward, resetting the device.

[0031] Please refer to Figures 1 - 6, on the basis of the above embodiments, in another embodiment of the present invention, a clamping and protecting device 5 is provided at the upper end of the main body 1. The clamping and protecting device 5 includes a connecting rod 501; a short rod 502; a first torsion spring 503; a rotating rod 504; a rotating rod 505; an L-shaped rod 506; a clamping piece 507; a transmission rod 508; a rotating block 509; a second torsion spring 510 and a protecting frame 511. The output end of the air cylinder 401 is fixedly connected to the outer wall of the connecting rod 501. When the air cylinder 401 is started, the connecting rod 501 moves forward. The upper end of the main body 1 is rotatably connected to the lower end of the short rod 502. The upper end of the main body 1 is fixedly connected to one end of the first torsion spring 503. The other end of the first torsion spring 503 is fixedly connected to the lower end of the rotating rod 504. And the upper end of the short rod 502 is fixedly connected to the lower end of the rotating rod 504. When the connecting rod 501 moves forward, it hits one end of the rotating rod 505, causing the rotating rod 505 to rotate around the short rod 502. The outer wall of the rotating rod 504 is rotatably connected to the inner wall of the rotating rod 505. The outer wall of the rotating rod 505 is rotatably connected to the inner wall of the L-shaped rod 506. And the lower end of the L-shaped rod 506 is slidably connected to the upper end of the main body 1. When the rotating rod 505 rotates, it drives one end of the rotating rod 504 to move. At this time, the other end of the rotating rod 505 drives the L-shaped rod 506 to slide on the upper end of the main body 1. The inner side of the L-shaped rod 506 is fixedly connected to the outer side of the clamping piece 507. When the L-shaped rod 506 slides on the upper end of the main body 1, it drives the clamping piece 507 to move synchronously to clamp the wire. The lower end of the connecting frame 406 is fixedly connected to the upper end of the transmission rod 508. The outer side of the platform 402 is rotatably connected to the inner side of the rotating block 509. When the platform 402 slides forward and drives the rotating block 509 to move forward, the rotating block 509 collides with the transmission rod 508 and rotates. The outer wall of the rotating block 509 is fixedly connected to the inner wall of the protecting frame 511. When the transmission rod 508 rotates, it drives the protecting frame 511 to rotate synchronously. The outer side of the platform 402 is fixedly connected to one end of the second torsion spring 510. The other end of the second torsion spring 510 is fixedly connected to the inner side of the protecting frame 511. When the rotating block 509 loses the extrusion of the transmission rod 508, it quickly resets under the action of the second torsion spring 510, driving the protecting frame 511 to rotate synchronously to protect the guillotine 403.

[0032] By providing the clamping and protecting device 5 in the present invention, when the connecting rod 501 moves, the connecting rod 501 squeezes the rotating rod 504, causing the rotating rod 504 to rotate. And through the cooperation of the short rod 502 and the rotating rod 505, the L-shaped rod 506 slides on the surface of the main body 1 and drives the clamping piece 507 to be below the incision of the guillotine 403 to tighten the wire, aiming at the situation that the force of the bundled wire is dispersed, preventing the guillotine 403 from failing to cut off the wire at one time due to the dispersed force on the wire.

[0033] In the present invention, by providing a clamping protection device 5, when the platform 402 moves, the rotating block 509 moves away from the transmission rod 508, squeezing the rotating block 509 to rotate, so that the protection frame 511 is opened or closed. Thus, when the guillotine 403 is in use, the protection frame 511 does not affect the guillotine 403. When not in use, the guillotine 403 is protected to prevent accidental injury caused by the guillotine 403.

[0034] At the upper end of the main body 1, there is a knocking device 6 for knocking off the residual wire scraps after shearing, including a U-shaped rod 601; an L-shaped hole 602; a squeezing block 603; a sliding block 604; a return spring 605; a connecting block 606; a small rotating shaft 607; a knocking rod 608 and a third torsion spring 609. The inner side of the transmission rod 508 is fixedly connected to the outer side of the U-shaped rod 601. After the platform 402 moves forward, the U-shaped rod 601 gradually approaches the platform 402. An L-shaped hole 602 is opened on the platform 402, and the U-shaped rod 601 can pass through the L-shaped hole 602. The upper end of the U-shaped rod 601 is fixedly connected to the lower end of the squeezing block 603. When the U-shaped rod 601 approaches the platform 402, it drives the squeezing block 603 to move synchronously close to the platform 402. The rear end of the platform 402 is slidably connected to the front end of the sliding block 604. When the squeezing block 603 approaches the platform 402, the squeezing block 603 collides with the sliding block 604. The front end of the sliding block 604 is fixedly connected to one end of the return spring 605, and the other end of the return spring 605 is fixedly connected to the rear end of the platform 402. After the squeezing block 603 collides with the sliding block 604, the sliding block 604 squeezes the return spring 605. The inner side of the platform 402 is fixedly connected to the outer side of the connecting block 606. The lower end of the connecting block 606 is fixedly connected to the upper end of the small rotating shaft 607. The outer wall of the small rotating shaft 607 is rotatably connected to the inner wall of the knocking rod 608. When the sliding block 604 squeezes the return spring 605, the sliding block 604 impacts one end of the knocking rod 608, causing the knocking rod 608 to rotate around the small rotating shaft 607, and the other end of the knocking rod 608 knocks on the guillotine 403. One end of the third torsion spring 609 is fixedly connected to the lower end of the connecting block 606, and the other end of the third torsion spring 609 is fixedly connected to the upper end of the knocking rod 608. When the knocking rod 608 loses the extrusion, under the action of the third torsion spring 609, it rotates and resets around the connecting block 606.

[0035] In the present invention, by providing the knocking device 6, when the U-shaped rod 601 moves, it drives the squeezing block 603 to pass through the L-shaped hole 602, causing the sliding block 604 to slide on the main body 1 and impact the knocking rod 608. Through the cooperation of the connecting block 606 and the small rotating shaft 607, the knocking rod 608 knocks on the guillotine 403. Conversely, the U-shaped rod 601 drives the squeezing block 603 to pass through the L-shaped hole 602 and return to the original position, squeezing the sliding block 604 again, so that the knocking rod 608 performs a secondary knock on the guillotine 403, causing the scraps remaining after cutting the wire on the guillotine 403 to fall off, preventing the residue from squeezing and affecting the flatness of the wire cut, thereby affecting the accuracy of the detection.

[0036] During the operation of this embodiment: When the cylinder 401 pushes, the connecting rod 501 moves forward. When the connecting rod 501 moves forward, it impacts one end of the rotating rod 505, causing the rotating rod 505 to rotate around the short rod 502. When the rotating rod 505 rotates, it drives one end of the rotating rod 504 to move. At this time, the other end of the rotating rod 505 drives the L-shaped rod 506 to slide on the upper end of the main body 1. When the L-shaped rod 506 slides on the upper end of the main body 1, it drives the clamping piece 507 to move synchronously to clamp the wire. At the same time, the platform 402 slides forward and drives the rotating block 509 to move forward. When the rotating block 509 moves forward, the rotating block 509 collides with and rotates the transmission rod 508. When the transmission rod 508 rotates, it drives the protective frame 511 to rotate synchronously, and releases the guillotine knife 403 to cut the wire; conversely, when the cylinder 401 pulls, the connecting rod 501 moves backward. When the connecting rod 501 moves backward, the rotating rod 505 that loses the extrusion of the connecting rod 501 is reset under the action of the first torsion spring 503. When the rotating rod 505 performs the reset movement, it drives one end of the rotating rod 504 to move. At this time, the other end of the rotating rod 505 drives the L-shaped rod 506 to slide on the upper end of the main body 1. When the L-shaped rod 506 slides on the upper end of the main body 1, it drives the clamping piece 507 to perform a synchronous reset movement. At the same time, the platform 402 slides backward and drives the rotating block 509 to move backward. When the rotating block 509 moves backward, the rotating block 509 loses the extrusion of the transmission rod 508 and quickly resets under the action of the second torsion spring 510. When the rotating block 509 resets, it drives the protective frame 511 to rotate synchronously to protect the guillotine knife 403 and prevent accidental touch.

[0037] After the platform 402 moves forward and disengages from the connection frame 406, the U-shaped rod 601 gradually approaches the platform 402. When the U-shaped rod 601 approaches the platform 402, it drives the extrusion block 603 to move synchronously closer to the platform 402. When the extrusion block 603 approaches the platform 402, the extrusion block 603 collides with the slider 604. After the extrusion block 603 collides with the slider 604, the slider 604 squeezes the return spring 605. At this time, the U-shaped rod 601 drives the extrusion block 603 to pass through the L-hole 602. When the slider 604 squeezes the return spring 605, the slider 604 hits one end of the knocking rod 608, causing the knocking rod 608 to rotate around the small rotating shaft 607, and the other end of the knocking rod 608 knocks the guillotine 403 to knock off the sundries sheared on the guillotine 403. Conversely, when the platform 402 moves backward, it contacts the connection frame 406. At this time, the U-shaped rod 601 gradually moves away from the platform 402. When the U-shaped rod 601 moves away from the platform 402, it drives the extrusion block 603 to move synchronously away from the platform 402 and pass through the L-hole 602, squeezing the slider 604. After the extrusion block 603 collides with the slider 604, the slider 604 squeezes the return spring 605. When the slider 604 squeezes the return spring 605, the slider 604 hits one end of the knocking rod 608, causing the knocking rod 608 to rotate around the small rotating shaft 607, and the other end of the knocking rod 608 knocks the guillotine 403 to knock off the sundries sheared on the guillotine 403. At the same time, after the U-shaped rod 601 drives the extrusion block 603 to pass over the slider 604, the knocking rod 608 that loses the extrusion rotates and resets around the connection block 606 under the action of the third torsion spring 609.
