Description

Technical Field

[0001] This invention belongs to the field of shockproof device technology, specifically a shockproof device for power supply lines. Background Technology

[0002] During power construction, high-voltage overhead lines are often high up and have long spans. When the cables are subjected to wind, they will vibrate. When the cables vibrate, the working conditions at the cable suspension point are the most unfavorable. Due to repeated vibrations, the cables will suffer fatigue damage due to periodic bending. To prevent this from happening, anti-vibration devices are usually installed on the cables near the insulators.

[0003] Utility model patent CN218919933U discloses a vibration damping device for power transmission lines, relating to the field of vibration damping technology for power transmission lines. This vibration damping device aims to solve the problem in existing technologies that cannot adapt to the installation and adjustment of vibration damping hammer weights for cables of different sizes. The device includes an upper clamping plate, with a lower clamping plate hinged to its rear side. Both the upper and lower clamping plates have arc-shaped plates on their inner sides. Several springs connect the arc-shaped plates to the inner walls of both the upper and lower clamping plates, accommodating the installation of cables of different sizes. Connecting plates are welded to the front sides of both the upper and lower clamping plates for easy installation and fixation. A base is welded to the lower surface of the lower clamping plate, with steel strands on both the front and rear sides inside the base. Fixing plates are fixed at both ends of the steel strands. A sleeve rod is welded to the side of the fixing plate away from the steel strands, and several counterweights are movably fitted onto the sleeve rod, allowing adjustment of the vibration damping hammer weight according to different cable sizes, ensuring the device's vibration damping effect.

[0004] In the aforementioned existing technologies, vibration damping devices rely on vibration dampers to achieve the purpose of vibration damping for power lines. However, the overall structure of the device is not convenient to install and use, and insufficient installation tightness affects installation stability. Furthermore, the vibration dampers are not easy to disassemble, making maintenance and repair inconvenient. Therefore, there is a need to design a vibration damping device for power supply lines. Summary of the Invention: The purpose of this invention is to provide a shockproof device for power supply lines to solve the above-mentioned problems, thereby resolving the issues mentioned in the background art.

A guide rod is slidably sleeved inside the push rod, which is fixedly connected to the limiting seat. A first spring is provided on the outer side of the guide rod. An insert block is fixedly connected to the end of the push rod away from the magnetic rod, and the insert block is slidably connected to the connecting strip. This connecting mechanism facilitates the installation and fixation of the overall structure.

[0007] Preferably, one end of the first spring is fixedly connected to the push rod, and the other end of the first spring is fixedly connected to the limiting seat. By designing the first spring, the force of the first spring can be applied to the push rod.

[0008] Preferably, the connecting strip has a slot inside, and a plug is slidably connected inside the slot. By designing the slot, the plug can slide inside the slot.

[0009] Preferably, the mounting mechanism includes positive and negative screws. Two symmetrically distributed positive and negative screws are rotatably connected to the inside of the mounting base via bearings. Rotating seats are fixedly connected to both ends of the positive and negative screws. The rotating seats have internal hexagonal slots. Two symmetrically distributed sliders are threaded to the outside of the positive and negative screws. The sliders are slidably connected to the mounting base. A sliding rod is fixedly connected to the top of each slider, and the sliding rod is slidably connected to the mounting base. A connecting rod is fixedly connected to the top of the sliding rod, and the connecting rod is slidably connected to the mounting base and a clamping block. A retaining groove is formed inside the positive and negative screws. A retaining ball is movably fitted inside the retaining groove. A positioning seat is movably fitted outside the retaining ball. The positioning seat is rotatably connected to the positive and negative screws and fixedly connected to the mounting base. A support block is movably fitted outside the retaining ball, and the support block is slidably connected to the positioning seat. A fixing rod is slidably fitted inside the support block, and fixedly connected to the positioning seat. A second spring is provided on the outside of the fixing rod. The design of the installation mechanism facilitates the assembly and disassembly of the vibration damper.

[0010] Preferably, a guide block is fixedly connected to the bottom of the slider, and the guide block is slidably connected to the mounting base. By designing the guide block, the movement of the slider can be guided.

[0011] Preferably, there are multiple slots, which are evenly distributed inside the positive and negative screws. By designing multiple slots, the ball can roll into the slots at different positions.

[0013] The beneficial effects of this invention are as follows: This invention relates to a shock-absorbing device for power supply lines, which features convenient installation and fixing of the device and easy disassembly, inspection, and maintenance of the shock-absorbing hammer. In specific use, compared with traditional shock-absorbing devices for power supply lines, this shock-absorbing device for power supply lines has the following beneficial effects: Firstly, by designing the threaded engagement between the positive and negative screws and the slider, the slider can move horizontally when the rotating block is turned by a hex wrench, which in turn drives the positive and negative screws to rotate. The movement of the slider can drive the sliding rod, connecting rod, and clamping block to move. The power supply line can be clamped and fixed by the movement of the clamping block, realizing the installation and use of the overall structure. The installation is tight and the operation is convenient. At the same time, with the insertion and engagement of the ball and the slot, the positive and negative screws in the stationary state can be limited and locked, preventing the random rotation of the positive and negative screws from causing the clamping block to separate from the power supply line and affecting the stability of the device installation and use. Secondly, by designing the contact between the limiting block and the fixed seat, the fixed seat can be blocked and limited to achieve the connection and fixation between the fixed seat and the connecting seat, thereby achieving the purpose of installing and using the steel strand and hammer. With the cooperation of the steel strand and hammer, the power supply line can be protected against vibration. The connecting strip can be limited by the insertion of the plug and the slot, which in turn can limit the limiting block. When the push rod is pushed horizontally, the plug and the slot can be separated. Then the limiting block and the fixed seat can be separated, and the steel strand and hammer can be taken out, which is convenient for the inspection and maintenance of the steel strand and hammer.

The guide rod 891 is fixedly connected to the limiting seat 86. A first spring 892 is provided on the outside of the guide rod 891. One end of the first spring 892 is fixedly connected to the push rod 89, and the other end of the first spring 892 is fixedly connected to the limiting seat 86. By designing the first spring 892, the force of the first spring 892 can act on the push rod 89. An insert block 893 is fixedly connected to the end of the push rod 89 away from the magnetic suction rod 88. The insert block 893 is slidably connected to the connecting strip 85. A slot 894 is opened inside the connecting strip 85. The insert block 893 is slidably connected inside the slot 894. By designing the slot 894, the insert block 893 can slide inside the slot 894. By designing the connecting mechanism 8, the installation and fixation of the overall structure are facilitated.

[0017] The mounting mechanism 9 includes positive and negative screws 91. Two symmetrically distributed positive and negative screws 91 are rotatably connected to the inside of the mounting base 1 via bearings. Rotating seats 92 are fixedly connected to both ends of each positive and negative screw 91. The rotating seats 92 have internal hexagonal grooves 93. Two symmetrically distributed sliders 94 are threaded to the outside of each positive and negative screw 91. The sliders 94 are slidably connected to the mounting base 1. A guide block 95 is fixedly connected to the bottom of each slider 94. Block 95 is slidably connected to mounting base 1. Guide block 95 guides the movement of slider 94. A slide rod 96 is fixedly connected to the top of slider 94, and slide rod 96 is slidably connected to mounting base 1.

A slot 98 is provided inside the positive and negative screw 91, and a retaining ball 99 is movably fitted inside the slot 98. There are multiple slots 98 evenly distributed inside the positive and negative screws 91. By designing multiple slots 98, the ball 99 can roll into the slots 98 at different positions. A positioning seat 991 is movably sleeved on the outside of the ball 99. The positioning seat 991 is rotatably connected to the positive and negative screws 91 and fixedly connected to the mounting base 1. A support block 992 is movably sleeved on the outside of the ball 99 and slidably connected to the positioning seat 991. A fixing rod 993 is slidably sleeved inside the block 992. The fixing rod 993 is fixedly connected to the positioning seat 991. A second spring 994 is provided on the outside of the fixing rod 993. One end of the second spring 994 is fixedly connected to the support block 992, and the other end of the second spring 994 is fixedly connected to the positioning seat 991. By designing the second spring 994, the force of the second spring 994 can be applied to the support block 992. By designing the installation mechanism 9, it is convenient to disassemble and assemble the anti-vibration hammer.

[0018] The usage state of this invention is as follows: When the device needs to be installed and used, first place the mounting base 1 on the power supply line, then insert the hex wrench into the interior hexagonal slot 93 and forcefully rotate the rotating base 92. The rotating base 92 drives the positive and negative screws 91 to rotate, causing the slider 94 to perform threaded movement. The sliders 94 at both ends will move in opposite directions. The slider 94 drives the guide block 95 to move horizontally. At the same time, the slider 94 will drive the slide rod 96 and the connecting rod 97 to move horizontally. The connecting rod 97 will drive the clamping block 2 to move horizontally, so that the clamping block 2 contacts the power supply line. At this time, the power supply line can be clamped and fixed, thus achieving the purpose of installing and fixing the overall structure.

[0019] When the positive and negative screw 91 rotates, it will rotate inside the positioning seat 991. The arc surface of the slot 98 inside the positive and negative screw 91 will squeeze and push the ball 99, causing it to roll downwards. The ball 99 will push the support block 992 downwards, and the support block 992 will slide along the fixed rod 993. The support block 992 will press down the second spring 994, which can separate the ball 99 from the slot 98. As the positive and negative screw 91 rotates, when the positive and negative screw 91 is stationary, the elastic action of the second spring 994 will give the support block 992 an upward counter-force, which can push the ball 99 into the slot 98 in another position. At this time, the stationary positive and negative screw 91 can be limited and locked to prevent the random rotation of the positive and negative screw 91 from causing the clamping block 2 to separate from the power supply line, affecting the stability of the device installation and use.

[0020] Once the device is installed, the combined use of the steel strand 6 and the hammer 7 will provide shock protection for the power supply line. When it is necessary to disassemble the steel strand 6 and hammer 7, push the push rod 89 horizontally. The push rod 89 slides along the guide rod 891 and compresses the first spring 892. At the same time, the push rod 89 will drive the magnetic suction rod 88 to move and also drive the insertion block 893 to move horizontally. When the magnetic suction rod 88 is attracted to the magnet 87, the insertion block 893 will slide out from the slot 894. Then, pull the connecting bar 85 upward. The connecting bar 85 will drive the guide rod 84 to move upward. The guide rod 84 will drive the limit block 81 to move upward. The limit block 81 will drive the lower magnetic suction block 82 to move upward. When the lower magnetic suction block 82 is attracted to the upper magnetic suction block 83, the limit block 81 will separate from the fixing seat 5 and the steel strand 6. Then, move horizontally, and the fixing seat 5 can be removed from the connecting seat 4. The steel strand 6 and hammer 7 can then be removed for easy inspection and maintenance of the steel strand 6 and hammer 7.
