Description

Technical Field

[0001] This utility model relates to the field of jumper string technology, specifically jumper strings. Background Technology

[0002] In high-voltage transmission lines, jumper strings are used to connect the conductors on both sides of the tension tower to ensure continuous current transmission while maintaining insulation of the tower. As a key component connecting the tower and the conductor, the reliability of the jumper connection directly affects the safety of power grid operation. The jumper clamps of traditional jumper strings are usually fastened with ordinary nuts. Factors such as wind vibration and temperature changes in outdoor environments can easily cause the bolts and nuts to loosen, leading to jumper detachment or poor contact. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a jumper string to solve the problems mentioned in the background section.

[0004] Traditional jumper wire clamps are usually secured with ordinary nuts. However, factors such as wind vibration and temperature changes in outdoor environments can easily cause the bolts and nuts to loosen, leading to jumper wires falling off or poor contact.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A jumper string includes a buckle block and an insulating string. The top of the buckle block is fixedly connected to the insulating string, and the bottom of the insulating string is fixedly connected to a hanging ring. The bottom of the hanging ring is fixedly connected to a first jumper clamp plate via a string clamp. The bottom of the first jumper clamp plate is detachably connected to a second jumper clamp plate via bolts and nuts. A wire groove is provided between the first and second jumper clamp plates. A ratchet is fixedly connected to the outside of the nut. A support frame is fixedly connected to the bottom of the second jumper clamp plate. A rotating shaft is rotatably connected between the bottom of the second jumper clamp plate and the support frame. A pawl is fixedly connected to one end of the rotating shaft. The pawl works in conjunction with the ratchet. A torsion spring is fixedly connected to one side of the pawl and the support frame.

[0007] Preferably, a fixing plate is fixedly connected to the bottom of the second jumper clamp, and a connecting rod is symmetrically slidably connected inside the fixing plate, with one end of the connecting rod rotatably connected to a ratchet.

[0008] Preferably, a connecting plate is fixedly connected to one side of the fixed plate, a movable plate is slidably connected inside the connecting plate, and one side of the movable plate is fixedly connected to the connecting rod.

[0009] Preferably, a rotating plate is rotatably connected to one side of the connecting plate, and adjusting rods are rotatably connected to both ends of the rotating plate.

[0010] Preferably, the end of the adjusting rod away from the rotating plate is rotatably connected to the moving plate.

[0011] Preferably, a turntable is fixedly connected to one side center of the rotating plate via a fixing rod.

[0012] Preferably, a spring is fixedly connected between the end of the connecting rod away from the pawl and the fixing plate.

[0013] This invention provides a jumper string. Compared with the prior art, it has the following advantages:

[0014] 1. This jumper string enhances stability through a ratchet and pawl anti-loosening mechanism. The ratchet and pawl on the outside of the nut form a one-way locking structure. The elastic restoring force of the torsion spring prevents the nut from loosening on its own due to external forces such as vibration, ensuring the long-term reliability of the jumper connection.

[0015] 2. This jumper string is equipped with a fixed plate, connecting rod, spring, rotating plate, adjusting rod, connecting plate, moving plate, ratchet, pawl and turntable. The turntable rotates the adjusting rod through the rotating plate, the adjusting rod moves the connecting rod through the moving plate, and the moving connecting rod moves the pawl, controlling the pawl to move away from the ratchet, which facilitates the disassembly and assembly of bolts and nuts.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-5 This utility model provides a technical solution: a jumper string, including a buckle block 1 and an insulating string 2. The top of the buckle block 1 is fixedly connected to the insulating string 2, and the bottom of the insulating string 2 is fixedly connected to a hanging ring 3. The hanging ring 3 fixes the insulating string 2 to the tower pole. The bottom of the hanging ring 3 is fixedly connected to a first jumper clamp plate 5 via a string clamp 4. The bottom of the first jumper clamp plate 5 is detachably connected to a second jumper clamp plate 9 via bolts 8 and nuts 23, which facilitates the assembly and disassembly of the first jumper clamp plate 5 and the second jumper clamp plate 9. A wire groove 7 is provided between the first jumper clamp plate 5 and the second jumper clamp plate 9 for better fixation of the jumper. A ratchet 10 is fixedly connected to the outside of the nut 23. The rotation of the nut 23 causes... The ratchet 10 rotates, and a support frame 20 is fixedly connected to the bottom of the second jumper clamp 9. A rotating shaft 21 is rotatably connected between the bottom of the second jumper clamp 9 and the support frame 20. A pawl 11 is fixedly connected to one end of the rotating shaft 21. The pawl 11 rotates, causing the rotating shaft 21 to rotate. The pawl 11 works in conjunction with the ratchet 10, and the pawl 11 restricts the rotation direction of the ratchet 10. A torsion spring 22 is fixedly connected between one side of the pawl 11 and the support frame 20. The rotation of the pawl 11 causes one end of the torsion spring 22 to rotate. The torsion spring 22 rotates and deforms. When the pawl 11 loses its pushing force, under the action of the elastic force, the torsion spring 22 takes the pawl 11 back to the two teeth on the outside of the ratchet 10.

[0024] Furthermore, a fixing plate 12 is fixedly connected to the bottom of the second jumper clamp 9. A connecting rod 13 is symmetrically slidably connected inside the fixing plate 12. One end of the connecting rod 13 is rotatably connected to the pawl 11. The movement of the connecting rod 13 moves one end of the pawl 11.

[0025] Furthermore, a connecting plate 17 is fixedly connected to one side of the fixed plate 12, and a movable plate 18 is slidably connected inside the connecting plate 17. The movable plate 18 moves along the inside of the connecting plate 17, and one side of the movable plate 18 is fixedly connected to the connecting rod 13. The movement of the movable plate 18 moves the connecting rod 13 along with it.

[0026] Furthermore, a rotating plate 15 is rotatably connected to one side of the connecting plate 17, and adjusting rods 16 are rotatably connected to both ends of the rotating plate 15. The rotating plate 15 rotates, causing the two sets of adjusting rods 16 to move.

[0027] Furthermore, the end of the adjusting rod 16 away from the rotating plate 15 is rotatably connected to the moving plate 18, and the movement of the adjusting rod 16 moves the moving plate 18.

[0028] Furthermore, a turntable 19 is fixedly connected to the center of one side of the rotating plate 15 via a fixing rod. The rotation of the turntable 19 causes the rotating plate 15 to rotate via the fixing rod.

[0029] Furthermore, a spring 14 is fixedly connected between the end of the connecting rod 13 away from the pawl 11 and the fixed plate 12. When the connecting rod 13 moves, it compresses the spring 14. The spring 14 generates elastic force when it is compressed. When the spring 14 loses its compressive force, it returns to its original position with the connecting rod 13 under the action of the elastic force.

[0030] In use, the jumper wire string is fixed to the tower pole by the fastener 1, and then the jumper wire is placed in the wire groove 7 between the first jumper wire clamp 5 and the second jumper wire clamp 9. The nut 23 is rotated, and the jumper wire between the first jumper wire clamp 5 and the second jumper wire clamp 9 is fixed by the nut 23 and the bolt 8. After fixing, the pawl 11 is located between the two teeth on the outside of the ratchet 10 to prevent the nut 23 from turning backward, which would cause the connection between the first jumper wire clamp 5 and the second jumper wire clamp 9 to loosen and affect the fixing effect of the jumper wire. When it is necessary to remove the jumper wire, the turntable 19 is rotated, and the turntable 19 is connected by the fixing rod. The rotating plate 15 rotates, which in turn rotates the two sets of adjusting rods 16. The adjusting rods 16 rotate, which in turn moves the moving plate 18 within the connecting plate 17. The moving plate 18 moves the two sets of connecting rods 13, which in turn compress the spring 14. As the connecting rods 13 move, they also move the pawl 11, causing one end of the pawl 11 to move away from one side of the ratchet 10, thus releasing the restriction on the nut 23. This makes it easier for the operator to disassemble the bolt 8 and the nut 23, thereby removing the jumper cable from between the first jumper cable clamp 5 and the second jumper cable clamp 9.
