Description

Technical Field

[0001] The present invention relates to the technical field of spacer bars, and in particular to a fixing structure for interphase spacer bars of a transmission line. Background Art

[0002] Under the influence of wind, breeze vibration of transmission lines occurs most frequently, sometimes lasting for days or more. This can lead to fatigue breakage of wire strands, damage to hardware and tower components, and limit the operating stress of the conductors. Overhead transmission lines typically use multiple sub-conductors connected in parallel to transmit power. To prevent the sub-conductors from adhering to each other, multiple spacers are installed in each section. The use of spacers ensures that the spacing between the sub-conductors remains constant to meet electrical performance requirements, reduces surface potential gradients, and prevents electromagnetic forces between the conductor bundles in the event of a short circuit, which could cause mutual attraction and collision. Spacers also have a certain inhibitory effect on sub-span solitary swings and breeze vibration.

[0025] Furthermore, the control box 2 is fixedly arranged on one side of the vertical frame 1; the electric telescopic rod 3 is fixedly arranged on the inside of the vertical frame 1; the sliding seat 4 is slidably arranged in the vertical frame 1 and is located above the electric telescopic rod 3; the side of the sliding seat 4 has a plurality of bevel teeth 41; the first clamping block 5 is fixedly arranged on the top of the sliding seat 4; one end of the elastic mechanism 6 is connected to the sliding seat 4, and the other end is connected to the vertical frame 1, for applying a reset pulling force to the sliding seat 4; The guide frame 7 is fixedly arranged on one side of the vertical frame 1 and is located on the top of the control box 2; the second clamping block 8 is fixedly arranged on the inner side of the guide frame 7 and is located above the first clamping block 5; the clamping mechanism 9 is arranged on the guide frame 7, and is used to clamp one of the bevel teeth 41 of the sliding seat 4, thereby locking the sliding seat 4; the mounting hook 10 is arranged on the clamping mechanism 9.

[0026] In this embodiment, the control box 2 is installed on one side of the vertical frame 1, and the control box 2 contains a control circuit board and a battery, etc.; the sliding seat 4 can drive the first clamping block 5 to move; the purpose of providing multiple bevel teeth 41 is to adapt to power lines of different diameters. When the sliding seat 4 drives the first clamping block 5 and the second clamping block 8 to close and clamp the power line, the clamping mechanism 9 clamps the corresponding bevel tooth 41 to lock the sliding seat 4; the shape of the guide frame 7 has a guiding function, which can smoothly guide the power line between the first clamping block 5 and the second clamping block 8; the first clamping block 5 and the second clamping block 8 are both made of polyurethane material, which has good flexibility and elasticity, can adapt to the bending and twisting of the power line, and at the same time ensure that there will be no side slip after hanging, and effectively protect the hung power line from wear; in specific use, the two ends of the interphase spacer are each connected to a fixing structure described in this application, specifically connected to the bottom end of the vertical frame 1, and the drone is used to carry the hanging ring 100, and then the hanging ring 100 is hung on the carrying hook 10 The electric telescopic rod 3 is started, pushing the sliding seat 4 so that the first clamping block 5 approaches the second clamping block 8 until the transmission line is clamped. Then, the clamping mechanism 9 clamps the corresponding bevel teeth 41, so that the sliding seat 4 is locked, and then the electric telescopic rod 3 is retracted. The two fixing structures described in the present application are respectively installed on the two transmission lines, thereby completing the installation of the interphase spacer. When disassembly is required, the drone is used to carry the hanging ring 100 and hang it in the carrying hook 10. Then, the clamping mechanism 9 is released, and the elastic mechanism 6 drives the sliding seat 4 to slide and reset, so that the first clamping block 5 is away from the second clamping block 8 and no longer clamps the transmission line. The drone is used to remove the entire device to complete the disassembly. The use of drones for installation solves the problems of high labor intensity, low work efficiency and high safety risks when installing interphase spacers manually at high altitude.

[0027] Furthermore, the vertical frame 1 has two connecting ears 11 , and the two connecting ears 11 are respectively located at the bottom of the vertical frame 1 .

[0028] In this embodiment, the two connecting ears 11 have pin holes for installing pins to connect with the ends of the interphase spacer bars.

[0029] Furthermore, the elastic mechanism 6 includes a fixed shaft 61, a fixed ring 62 and a tension spring 63; The fixed shaft 61 is fixedly arranged on the inner side of the vertical frame 1 ; the fixed ring 62 is fixedly arranged on one side of the sliding seat 4 ; one end of the tension spring 63 is connected to the fixed shaft 61 , and the other end is connected to the fixed ring 62 .

[0030] In this embodiment, when the sliding seat 4 drives the first clamping block 5 to approach the second clamping block 8, the tension spring 63 is stretched. When disassembling, after the clamping mechanism 9 releases the sliding seat 4, the tension spring 63 pulls the sliding seat 4 to reset, driving the first clamping block 5 away from the second clamping block 8.

[0031] Furthermore, the clamping mechanism 9 includes a first mounting shaft 91, a mounting block 92, a second mounting shaft 93, a clamping pin 94, a double torsion spring 95, a single torsion spring 96, a locking member 97 and a positioning pin 98; The first mounting shaft 91 is fixedly mounted on the inner side of the guide frame 7; the mounting block 92 is rotatably mounted on the first mounting shaft 91; the second mounting shaft 93 is fixedly mounted on the inner side of the mounting block 92; the bayonet 94 is rotatably mounted on the second mounting shaft 93; the positioning pin 98 is fixedly mounted on the inner side of the guide frame 7; the double torsion spring 95 is sleeved on the first mounting shaft 91; the single torsion spring 96 is sleeved on the second mounting shaft 93; the two torsion arms of the double torsion spring 95 are hung on the positioning pin 98; The double torsion spring 95 is used to apply an elastic return torque to the mounting block 92 so that the lower end of the mounting block 92 has a tendency to rotate away from the sliding seat 4; the single torsion spring 96 is used to apply an elastic return torque to the bayonet 94 so that the upper end of the bayonet 94 has a tendency to rotate toward the sliding seat 4; the locking member 97 is provided on the guide frame 7 and is used to lock the mounting block 92 so that the mounting block 92 cannot rotate and remains vertical.

[0032] In this embodiment, when the mounting block 92 is kept in a vertical state, the two torsion arms of the double torsion spring 95 have been bent and hooked on the positioning pin 98. Therefore, at this time, the double torsion spring 95 has accumulated elastic potential energy and applies an elastic reset torque to the mounting block 92, so that the lower end of the mounting block 92 has a rotation tendency away from the sliding seat 4; the mounting block 92 has a cavity inside, and the second mounting shaft 93 and the bayonet 94 are installed; one torsion arm of the single torsion spring 96 is against the bayonet 94, and the other torsion arm is against the mounting block 92. Therefore, when the When the upper end of the bayonet 94 is forced to rotate in the direction away from the sliding seat 4, the single torsion spring 96 will be compressed and accumulate elastic potential energy. When the upper end of the bayonet 94 is no longer under force, the single torsion spring 96 drives the bayonet 94 to rotate and reset, and keep it vertical again; during the installation process, the locking member 97 locks the mounting block 92, so that the mounting block 92 cannot rotate and remains vertical. When the sliding seat 4 drives the first clamping block 5 to approach the second clamping block 8, one of the bevel teeth 41 contacts the upper end of the bayonet 94, squeezing and pushing the bayonet 94 to one side, and the bayonet 94 The upper end will rotate toward the side away from the sliding seat 4. When the bevel tooth 41 completely passes the upper end of the bayonet 94, the bayonet 94 rotates and resets under the action of the single torsion spring 96, and is stuck under the bevel tooth 41. Then the next bevel tooth 41 contacts the bayonet 94 again, and the above action is repeated. Therefore, when the sliding seat 4 drives the first clamping block 5 to approach the second clamping block 8, it will not be blocked by the bayonet 94. However, when the sliding seat 4 drives the first clamping block 5 away from the second clamping block 8, it will be blocked by the bayonet 94. Similar to a toothed ratchet mechanism, it can only move in one direction; during the disassembly process, first loosen the locking piece 97 and no longer lock the mounting block 92, so that the mounting block 92 can rotate. At this time, under the action of the double torsion spring 95, the lower end of the mounting block 92 rotates in the direction away from the sliding seat 4, driving the latch 94 away from the sliding seat 4, and will no longer get stuck and block any of the bevel teeth 41. At this time, under the pull of the tension spring 63, the sliding seat 4 can be reset, driving the first clamping block 5 away from the second clamping block 8, and releasing the clamped power transmission line.

[0033] Furthermore, the locking member 97 includes a vertical housing 971 , a vertical stopper 972 and a ball screw 973 ; The vertical shell 971 is fixedly provided on one side of the guide rack 7 and is located on the top of the control box 2; the vertical block 972 is slidably connected to the guide rack 7 and is slidably connected to the vertical shell 971, and is located on the inner side of the guide rack 7; the vertical block 972 has a positioning hole 9721; the mounting hook 10 is fixedly provided on one side of the vertical block 972; the ball screw 973 is fixedly provided on the inner side of the guide rack 7, and the steel ball of the ball screw 973 is stuck in the positioning hole 9721.

[0034] In this embodiment, the vertical shell 971 and the guide frame 7 are surrounded by the vertical stop block 972 for sliding installation. The vertical stop block 972 blocks the side of the mounting block 92, and the mounting block 92 is locked and cannot rotate. However, it is subjected to the elastic reset torque applied by the double torsion spring 95, so that the lower end of the mounting block 92 has a rotation tendency away from the sliding seat 4, and the steel ball of the ball screw 973 is also stuck in the positioning hole 9721, locking the vertical stop block 972. When it is necessary to loosen the mounting block 92, the drone uses the carrying hanging ring 100 to pull up the carrying hook 10, The vertical block 972 is pulled up to squeeze the steel ball, so that the steel ball exits the positioning hole 9721. After the vertical block 972 slides up and no longer blocks the mounting block 92, under the action of the bidirectional torsion spring, the lower end of the mounting block 92 rotates in the direction away from the sliding seat 4, driving the latch 94 away from the sliding seat 4, thereby unlocking the sliding seat 4. When the fixed structure described in the present application below the interphase spacer is dismantled, the traction rope carried by the drone is fixed to the mounting hook 10 and then the traction rope is thrown. The ground personnel complete the unlocking by pulling the traction rope downward.

[0035] Furthermore, the vertical stopper 972 further has a strip-shaped limiting hole 9722; the locking member 97 further includes a limiting column 974; One end of the limiting column 974 is fixedly connected to the guide frame 7 , and the other end is fixedly connected to the vertical shell 971 and passes through the strip-shaped limiting hole 9722 .

[0036] In this embodiment, when the vertical stop block 972 is continuously pulled up and slid, it will disengage from the guide frame 7. Therefore, the limiting column 974 is provided to pass through the strip-shaped limiting hole 9722. When the vertical stop block 972 slides up to a certain extent, it will be stuck by the limiting column 974 to prevent it from disengaging.

[0037] Furthermore, the vertical stopper 972 further includes a locking hole 9723; the locking member 97 further includes a steering gear 975 and a locking block 976; The servo 975 is fixedly arranged on the inner side of the guide frame 7 ; the locking block 976 is fixedly arranged on the output end of the servo 975 .

[0038] In this embodiment, when the drone carrying hanging ring 100 hooks the carrying hook 10, the servo 975 is first started to rotate the locking block 976 and insert it into the locking hole 9723, completely locking the vertical block 972 to avoid shaking due to wind and other factors during installation, which may cause the vertical block 972 to unlock and loosen the installation block 92, affecting the installation process; after installation, the servo 975 drives the locking block 976 to withdraw from the locking hole 9723.

[0039] The present embodiment describes a transmission line interphase spacer fixing structure. When in use, the two ends of the interphase spacer are each connected to a fixing structure described in the present application, specifically connected to the bottom end of the vertical frame 1. The drone is used to carry the hanging ring 100, and then the hanging ring 100 is hung in the carrying hook 10, so as to lift the whole body, fly to the side of the two transmission lines and adjust the position. Under the guidance of the guide frame 7, the transmission line is finally moved between the first clamping block 5 and the second clamping block 8. The electric telescopic rod 3 is started to push the sliding seat 4, so that the first clamping block 5 approaches the second clamping block 8 until the transmission line is clamped, and then the clamping mechanism 9 clamps the corresponding one. The bevel teeth 41 lock the sliding seat 4, and then the electric telescopic rod 3 retracts; the two fixed structures described in this application are respectively installed on two power transmission lines, thereby completing the installation of the interphase spacer; when disassembly is required, the drone is used to carry the hanging ring 100, which is hung in the carrying hook 10, and then the clamping mechanism 9 is released. The elastic mechanism 6 drives the sliding seat 4 to slide and reset, so that the first clamping block 5 is away from the second clamping block 8 and no longer clamps the power transmission line. The whole is removed by using a drone to complete the disassembly; using a drone for installation solves the problem of high labor intensity, low working efficiency, and high safety risks when installing interphase spacer bars manually at high altitude. The disassembly method of this application is purely mechanical disassembly, which can still be stably disassembled even after long-term use.
