Description

Technical Field

[0001] The invention relates to the technical field of cable lightning protection, in particular to a circuit construction cable lightning protection device. Background Art

[0002] When using cables, they need to be used in conjunction with lightning arresters. When the working voltage is normal, the lightning arrester is insulated from the ground and has no effect on the circuit. However, when lightning invades or the voltage increases, the insulation between the lightning arrester and the ground will be broken down and discharged, introducing lightning current or overvoltage into the earth, thereby limiting the voltage or current and playing a protective role.

[0003] In the prior art, lightning arresters are generally fixed on two arc-shaped mounting frames by bolt connection, and then the mounting frames are clamped on utility poles. Since the utility poles have a certain height, workers need to work at high altitudes. It takes a long time to operate multiple bolts at high altitudes because the bolts need to be removed or installed one by one, which is less convenient to use. As a result, workers have to work at high altitudes for a long time, which reduces their work safety. When workers install the clamping rings, they need to connect the fixing holes of the two clamping rings, which is particularly inconvenient when operating at high altitudes. Summary of the invention

[0004] In view of the problems in the prior art, the present invention provides a lightning protection device for circuit construction cables.

[0005] The technical solution adopted by the present invention to solve the technical problem is: a lightning arrester for a circuit construction cable, comprising a conjoined seat and a lightning arrester, one side of the lightning arrester is fixedly connected to a connecting ring, a plurality of slots arranged in an array are provided on the connecting ring, and a positioning slot is provided on one side of the connecting ring; The one-piece seat is rotatably connected to a symmetrically arranged clamping ring, the inner ring of each clamping ring is fixedly connected to a rubber layer, each clamping ring is fixedly connected to a mounting seat, one of the mounting seats is fixedly connected to a pressure bearing seat, the other mounting seat is rotatably connected to a rotating rod, the rotating rod is fixedly connected to a rotating plate, the side wall of the rotating plate is fixedly connected to an abutting rod, the rotating plate is slidably connected to a latch, two slots are provided on the outer wall of one of the clamping rings, and one side of the other clamping ring is fixedly connected to a mounting rod; The mounting rod is fixedly connected with an abutment ring, one side of the abutment ring is fixedly connected with a torsion spring, the mounting rod is rotatably connected with a rotating ring at a position corresponding to one side of the abutment ring, the rotating ring is provided with a receiving groove, a plurality of tooth blocks arranged in an array are fixedly connected inside the receiving groove, the mounting rod is fixedly connected with a support ring at a position corresponding to one side of the rotating ring, a plurality of round rods arranged in an array are rotatably connected to the support ring, one end of the round rod is fixedly connected with a driven gear at a position corresponding to the receiving groove, the other end of the round rod is fixedly connected with an extrusion block, a positioning block is fixedly connected at a position corresponding to the positioning groove on one side of the mounting rod, a plurality of lifting rods arranged in an array are slidably connected to a position corresponding to one side of the support ring on the mounting rod, the mounting rod is fixedly connected with a spring at a position corresponding to the lifting rod, and one end of the lifting rod is fixedly connected with a clamping rod.

[0006] Specifically, the specific shape of the one-piece seat is an S-shape, and the specific shape of the abutment rod is an L-shape.

[0012] Beneficial effects of the present invention: The present invention eliminates the need for workers to connect the two clamping rings, thus shortening the workers' high-altitude working time and improving the workers' work safety. The workers can directly use the crowbar to rotate the rotating ring, and the rotation of the rotating ring can cause the various components to be linked. The linkage of the various components can cause the various clamping rods to expand and move in directions away from each other. At this time, the connecting ring on the lightning arrester can be connected with the positioning block, and then the crowbar is separated from the rotating ring. The rotating ring loses the force of rotation and will be reset under the drive of the torsion spring.

Two slots 14 are provided on the outer wall of one of the clamping rings 6, and a mounting rod 15 is fixedly connected to one side of the other clamping ring 6; A butt ring 16 is fixedly connected to the mounting rod 15, and a torsion spring 17 is fixedly connected to one side of the butt ring 16. A rotating ring 18 is rotatably connected to a position on one side of the mounting rod 15 corresponding to the butt ring 16. A receiving groove 19 is provided on the rotating ring 18, and a plurality of tooth blocks 20 arranged in an array are fixedly connected inside the receiving groove 19. A supporting ring 21 is fixedly connected to a position on one side of the mounting rod 15 corresponding to the rotating ring 18, and a plurality of round rods 22 arranged in an array are rotatably connected to the supporting ring 21. A driven gear 23 is fixedly connected to one end of the round rod 22 at a position corresponding to the receiving groove 19, and an extrusion block 24 is fixedly connected to the other end of the round rod 22. A positioning block 25 is fixedly connected to a position on one side of the mounting rod 15 corresponding to the positioning groove 5. A plurality of lifting rods 26 arranged in an array are slidably connected to a position on one side of the mounting rod 15 corresponding to the support ring 21. A spring 27 is fixedly connected to a position on the mounting rod 15 corresponding to the lifting rod 26, and a clamping rod 28 is fixedly connected to one end of the lifting rod 26.

[0018] The specific shape of the one-piece seat 1 is an S-shaped setting, and the specific shape of the abutment rod 12 is an L-shaped setting. The one-piece seat 1 is convenient for providing support for the rotation of the clamping ring 6. The specific shape of the clamping rod 28 is an L-shaped setting. One end of the clamping rod 28 is slidably connected to the inside of the corresponding clamping slot 4, and one side of the positioning block 25 is slidably connected to the inside of the positioning slot 5. The connection between the clamping rod 28 and the clamping slot 4 is convenient for fixing the lightning arrester 2. A plurality of lever seats 29 arranged in an array are fixedly connected to the rotating ring 18. One side of the rotating ring 18 is fixedly connected to the torsion spring 17. The lever seat 29 is convenient for the staff to rotate the rotating ring 18 by a crowbar, and the torsion spring 17 is convenient for driving the rotating ring 18 to reset. The driven gears 23 are all located inside the accommodating grooves 19, and the driven gears 23 are all meshed with the tooth blocks 20. When the tooth blocks 20 rotate with the rotating ring 18, it is convenient to drive the driven gears 23 to rotate. The lifting rods 26 are all located in the hollow position of the springs 27, and one end of the springs 27 is fixedly connected to the clamping rods 28. The springs 27 are convenient to drive the clamping rods 28 to reset. A push handle 30 is fixedly connected to the top of the rotating plate 11. The specific shape of the push handle 30 is an O-shaped setting. The diameter of the slot 14 is larger than the diameter of the pin 13. The push handle 30 is convenient for pushing the rotating plate 11 to rotate. The diameter of the slot 14 is larger than the diameter of the pin 13, which is convenient for inserting the pin 13 into the slot 14.

[0019] When in use, the staff can rotate and open the two clamping rings 6 through the support of the one-piece seat 1, and then clamp them on the electric pole. At this time, the rubber layer 7 of the inner circle of the clamping ring 6 will fit with the outer wall of the electric pole. When the two clamping rings 6 clamp the electric pole, the two mounting seats 8 are in an adjacent state. Figure 1 , the rotating plate 11 can be directly rotated by pushing the handle 30, and the rotating plate 11 will drive the rotating rod 10 and the abutting rod 12 to rotate together. At this time, the rotating plate 11 and the abutting rod 12 will rotate with the rotating rod 10 as the center of the circle. The abutting rod 12 rotates upward to squeeze the outer wall of the pressure-bearing seat 9 which is inclined. At this time, the pressure-bearing seat 9 is squeezed by the abutting rod 12 and will passively drive the corresponding mounting seat 8 and the clamping ring 6 to approach the other clamping ring 6. At this time, the rubber layer 7 is squeezed and deformed to improve the fit with the pole, and then with the rotation of the rotating plate 11, the rotating plate 11 will drive the pin 13 to gradually correspond to the slot 14, which can be adjusted according to the actual situation. The actual use requirement makes the latch 13 correspond to the top slot 14 or the bottom slot 14. When the latch 13 corresponds to the slot 14, the latch 13 is pushed so that the latch 13 is connected to the inside of the slot 14. At this time, the deformed rubber layer 7 will have a great stress, which will cause the two clamping rings 6 to open outward. At this time, the latch 13 is already connected to the slot 14, and the two clamping rings 6 cannot complete the opening action. Instead, the latch 13 is tightly connected to the inside of the slot 14. At this time, the clamping ring 6 is installed, which is convenient to operate, eliminating the step of docking the two clamping rings 6 for the staff, which can shorten the high-altitude working time of the staff and improve the work safety of the staff; Then the staff can take out the lightning arrester 2, and then take out the crowbar with the other hand to rotate the rotating ring 18 through the lever seat 29. The rotation of the rotating ring 18 will cause the torsion spring 17 to deform, and the rotation of the rotating ring 18 will also drive the tooth block 20 to rotate. The rotation of the rotating ring 18 will drive multiple driven gears 23 to rotate together through the tooth block 20. The rotation of the driven gear 23 will drive the round rod 22 to rotate, and the round rod 22 will rotate under the support of the support ring 21. When the round rod 22 rotates, it will drive the extrusion block 24 to rotate. The rotation of the extrusion block 24 will squeeze the corresponding clamping rod 28. The clamping rod 28 is squeezed and moves in the direction away from the mounting rod 15. At this time, the clamping rod 28 is subjected to the opening movement, and the movement of the clamping rod 28 will drive the lifting rod 26 to move together. The lifting rod 26 is a guide for the movement of the clamping rod 28. The movement of the clamping rod 28 will also stretch the spring 27. When the clamping rod 28 is completely moved Afterwards, the staff holds the lightning arrester 2 so that the connecting ring 3 on one side of the lightning arrester 2 corresponds to the positioning groove 5 with the positioning block 25, and then connects the positioning groove 5 with the positioning block 25. After the connection is completed, the rotating ring 18 can be loosened. At this time, the torsion spring 17 will drive the rotating ring 18 to reset and rotate, and the tooth block 20, the driven gear 23, the round rod 22 and the extrusion block 24 will all be reset. At this time, the clamping rod 28 loses the extrusion of the extrusion block 24 and will be reset under the drive of the spring 27. The reset clamping rod 28 and the lifting rod 26 will both move in the direction of the initial movement, and the reset clamping rod 28 will be inserted into the clamping groove 4 on the connecting ring 3. At this time, the lightning arrester 2 is installed, which greatly shortens the time required for the installation of the lightning arrester 2, improves the convenience of installation of the lightning arrester 2, and further reduces the time for staff to work at high altitudes, thereby further improving the work safety of staff.
