Description

Technical Field

[0001] This utility model relates to the field of high-voltage surge arrester technology, specifically a high-voltage surge arrester base. Background Technology

[0002] A high-voltage surge arrester is a device used to protect electrical equipment from lightning overvoltage damage. In order to assist in the stable installation of high-voltage surge arresters, a high-voltage surge arrester base is required.

[0003] Traditional high-voltage surge arrester bases, used to assist in the installation of surge arresters, involve placing the bottom of the surge arrester on top of the base. Bolts are then passed through the inner walls of the bottom of the surge arrester and the inner walls of the base to help stabilize the surge arrester and the base. However, the traditional method involves repeatedly rotating the bolts to assist in the disassembly of the surge arrester and the base, which is time-consuming and labor-intensive, thus affecting the efficiency of the device. Furthermore, since high-voltage surge arresters are installed at high altitudes, they are subject to the influence of external wind forces over a long period of time, which can cause the surge arrester to sway. This can lead to the bolts shaking on the base and the inner walls of the surge arrester, making it easy for the bolt threads to strip during disassembly. Summary of the Invention

[0004] In view of the shortcomings of the prior art, this utility model provides a high-voltage surge arrester base to solve the problems mentioned in the background art.

[0005] This utility model provides the following technical solution: a high-voltage surge arrester base, including a base body, a base plate fixedly mounted on the bottom of the base body, a sliding groove opened on the top of the base body, an annular groove opened on the bottom of the inner wall of the sliding groove, a limiting plate rotatably connected to the inner wall of the annular groove, a support rod fixedly mounted on the top of the limiting plate, a surge arrester body fixedly mounted on the top of the support rod, a round rod slidably connected to the inner wall of the base body, and the outer edge of the round rod slidably sleeved with the inner wall of the limiting plate, a cylinder fixedly mounted on the outer edge of the base body, a round plate slidably sleeved on the inner wall of the cylinder, and the side of the round plate fixedly mounted with the side of the round rod.

[0006] As a preferred technical solution of this utility model, a spring is fixedly connected to the side of the circular plate, and the end of the spring away from the circular plate is fixedly connected to the side of the inner wall of the cylinder. An auxiliary groove is provided on the side of the cylinder. A spring is fixedly connected to the bottom of the inner wall of the base body. A protruding rod is fixedly connected to the top of the spring, and the shape and size of the convex surface at the top of the protruding rod are adapted to the shape and size of the concave surface at the bottom of the limiting plate.

[0007] As a preferred embodiment of this utility model, a connecting plate is fixedly mounted on the side of the circular plate, and an auxiliary plate is rotatably connected to the side of the connecting plate. The shape and size of the outer edge of the auxiliary plate are adapted to the shape and size of the inner wall of the auxiliary groove, and a pull rod is fixedly mounted on the side of the auxiliary plate.

[0008] As a preferred embodiment of this utility model, a side plate is fixedly mounted on the top of the base body, a threaded rod is rotatably sleeved on the inner wall of the side plate, a sleeve is slidably connected to the top of the base body, and the inner wall of the sleeve is threadedly connected to the outer edge of the threaded rod. An outer cylinder is fixedly mounted on the side of the sleeve, a slide cylinder is slidably sleeved on the inner wall of the outer cylinder, a clamping plate is fixedly mounted on the side of the slide cylinder, and a rubber pad is fixedly mounted on the inner wall of the clamping plate, with the inner wall of the rubber pad fitting against the outer edge of the support rod.

[0009] As a preferred embodiment of this utility model, a sliding rod is fixedly sleeved on the inner wall of the sliding cylinder, and the side of the sliding rod is fixedly assembled with the side of the clamping plate. An inner cylinder is slidably sleeved on the outer edge of the sliding rod, and the side of the inner cylinder is fixedly assembled with the side of the inner wall of the outer cylinder.

[0010] As a preferred embodiment of this utility model, a magnetic ring is fixedly mounted on the side of the slide cylinder, and a coil is fixedly sleeved on the inner wall of the outer cylinder, with the inner wall of the coil slidingly sleeved with the inner wall of the magnetic ring.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. This high-voltage surge arrester base, through the cooperation of the sliding groove and the limiting plate, pulls the rod away from the base body, thereby using the rod to drive the outer edge of the auxiliary plate through the inner wall of the auxiliary groove to the side of the cylinder. Then, the rod is rotated so that the side of the auxiliary plate overlaps with the side of the cylinder. The outer edge of the limiting plate passes through the inner wall of the sliding groove to the inner wall of the annular groove, and the bottom of the auxiliary limiting plate overlaps with the bottom of the inner wall of the annular groove. Then, the surge arrester body is rotated, thereby using spring two to push the convex rod upward, and the top convex surface of the auxiliary convex rod fits with the bottom concave surface of the limiting plate. Then, the rod is reversed, thereby using spring one to push the round rod to connect with the inner wall of the limiting plate, thus ensuring the stable installation of the surge arrester body.

[0013] 2. The high-voltage surge arrester base, through the cooperation of the threaded rod and the surge arrester body, rotates the threaded rod, thereby driving the sleeve to slide on the top of the base body. The sleeve, through the outer cylinder and the sliding cylinder, drives the inner wall of the rubber pad to fit against the outer edge of the support rod. When the surge arrester body shakes, the surge arrester body drives the clamping plate to move through the rubber pad. The clamping plate then drives the outer edge of the sliding cylinder to slide in the inner wall of the outer cylinder. The sliding cylinder then drives the outer edge of the magnet ring to slide in the inner wall of the coil. Thus, the coil generates electromagnetic damping on the magnet ring, thereby assisting the surge arrester body in reducing vibration. Attached Figure Description

[0022] Please see Figures 1-6A high-voltage surge arrester base includes a base body 1, a base plate 2 fixedly mounted on the bottom of the base body 1, a sliding groove 3 formed on the top of the base body 1, an annular groove 4 formed on the bottom of the inner wall of the sliding groove 3, a limiting plate 5 rotatably connected to the inner wall of the annular groove 4, a support rod 6 fixedly mounted on the top of the limiting plate 5, a surge arrester body 7 fixedly mounted on the top of the support rod 6, a round rod 8 slidably connected to the inner wall of the base body 1, and the outer edge of the round rod 8 slidably sleeved with the inner wall of the limiting plate 5, and the outer edge of the base body 1 fixedly... The device is equipped with a cylinder 9, and a circular plate 12 is slidably sleeved on the inner wall of the cylinder 9. The side of the circular plate 12 is fixedly assembled with the side of the circular rod 8. Through the cooperation of the limiting plate 5 and the annular groove 4, the shape and size of the outer edge of the limiting plate 5 are adapted to the shape and size of the inner wall of the sliding groove 3 and the inner wall of the annular groove 4, thereby ensuring that the outer edge of the limiting plate 5 passes through the inner wall of the sliding groove 3 to the inner wall of the annular groove 4. Then, the lightning arrester body 7 drives the limiting plate 5 to rotate, thereby assisting the outer edge of the limiting plate 5 to be limited to the inner wall of the annular groove 4.

[0023] In a preferred embodiment, a spring 10 is fixedly connected to the side of the circular plate 12, and the end of the spring 10 away from the circular plate 12 is fixedly connected to the side of the inner wall of the cylinder 9. An auxiliary groove 11 is provided on the side of the cylinder 9. A spring 2 16 is fixedly connected to the bottom of the inner wall of the base body 1, and a protruding rod 17 is fixedly connected to the top of the spring 2 16. The shape and size of the top convex surface of the protruding rod 17 are adapted to the shape and size of the bottom concave surface of the limiting plate 5. Through the cooperation of the spring 10 and the circular plate 12, the spring 10 pushes the circular plate 12 in the inner wall of the cylinder 9, thereby using the circular plate 12 to drive the outer edge of the circular rod 8 to align with the inner wall of the limiting plate 5, thus assisting the limiting plate 5 in positioning. Through the cooperation of the spring 2 16 and the protruding rod 17, the spring 2 16 pushes the protruding rod 17 upward in the inner wall of the base body 1, thereby assisting the top convex surface of the protruding rod 17 in positioning with the bottom concave surface of the limiting plate 5, thus assisting the limiting plate 5 in being fixed.

[0024] In a preferred embodiment, a connecting plate 13 is fixedly mounted on the side of the circular plate 12, and an auxiliary plate 14 is rotatably connected to the side of the connecting plate 13. The shape and size of the outer edge of the auxiliary plate 14 are adapted to the shape and size of the inner wall of the auxiliary groove 11. A pull rod 15 is fixedly mounted on the side of the auxiliary plate 14. Through the cooperation between the auxiliary plate 14 and the auxiliary groove 11, the pull rod 15 drives the outer edge of the auxiliary plate 14 through the inner wall of the auxiliary groove 11 to the side of the cylinder 9. Then, when the pull rod 15 is rotated, the side of the auxiliary plate 14 overlaps and limits the movement of the cylinder 9 when the circular plate 12 is pushed by the spring 10, thereby separating the outer edge of the auxiliary protrusion 17 from the inner wall of the limiting plate 5.

[0025] In a preferred embodiment, a side plate 19 is fixedly mounted on the top of the base body 1. A threaded rod 20 is rotatably sleeved on the inner wall of the side plate 19. A sleeve 18 is slidably connected to the top of the base body 1, and the inner wall of the sleeve 18 is threadedly connected to the outer edge of the threaded rod 20. An outer cylinder 21 is fixedly mounted on the side of the sleeve 18. A slide cylinder 22 is slidably sleeved on the inner wall of the outer cylinder 21. A clamping plate 27 is fixedly mounted on the side of the slide cylinder 22. A rubber pad 28 is fixedly mounted on the inner wall of the clamping plate 27, and the inner wall of the rubber pad 28 is in contact with the outer edge of the support rod 6. Through the cooperation of the threaded rod 20 and the sleeve 18, the rotation of the threaded rod 20 drives the sleeve 18 to move, thereby using the sleeve 18 to drive the clamping plate 27 and the rubber pad 28 to move, and assisting the inner wall of the rubber pad 28 to clamp and fit against the outer edge of the support rod 6.

[0026] In a preferred embodiment, a slide rod 23 is fixedly sleeved on the inner wall of the slide cylinder 22, and the side of the slide rod 23 is fixedly assembled with the side of the clamping plate 27. The outer edge of the slide rod 23 is slidably sleeved on the inner cylinder 24, and the side of the inner cylinder 24 is fixedly assembled with the side of the inner wall of the outer cylinder 21. Through the cooperation of the slide rod 23 and the clamping plate 27, the outer edge of the slide rod 23 slides in the inner wall of the inner cylinder 24, and the outer edge of the slide cylinder 22 slides in the inner wall of the outer cylinder 21. The inner wall of the slide cylinder 22 slides on the outer edge of the inner cylinder 24, thereby limiting the movement path of the clamping plate 27.

[0027] In a preferred embodiment, a magnet ring 25 is fixedly mounted on the side of the slide cylinder 22, and a coil 26 is fixedly sleeved on the inner wall of the outer cylinder 21. The inner wall of the coil 26 is slidably sleeved with the inner wall of the magnet ring 25. Through the cooperation of the magnet ring 25 and the coil 26, the magnet ring 25 is moved when the slide cylinder 22 moves, thereby the outer edge of the magnet ring 25 slides in the inner wall of the coil 26. The coil 26 generates electromagnetic damping on the magnet ring 25, thereby assisting the clamping plate 27 in driving the rubber pad 28 to perform shock absorption.

[0028] Working principle: When the device is in use, pull rod 15 is pulled away from the base body 1, thereby using pull rod 15 to drive the outer edge of auxiliary plate 14 through the inner wall of auxiliary groove 11 to the side of cylinder 9. Then, pull rod 15 is rotated so that the side of auxiliary plate 14 overlaps with the side of cylinder 9. The outer edge of limiting plate 5 passes through the inner wall of sliding groove 3 to the inner wall of annular groove 4, and the bottom of auxiliary limiting plate 5 overlaps with the bottom of the inner wall of annular groove 4. Then, the surge arrester body 7 is rotated, thereby using spring 16 to push protruding rod 17 upward. The top convex surface of auxiliary protruding rod 17 fits against the bottom concave surface of limiting plate 5. Then, pull rod 15 is reversed, thereby using spring 10 to push round rod 8 against limiting plate 17. The inner wall of 5 is connected to ensure the stable installation of the surge arrester body 7. Rotating the threaded rod 20 causes the sleeve 18 to slide on the top of the base body 1. The sleeve 18, through the outer cylinder 21 and the sliding cylinder 22, causes the inner wall of the rubber pad 28 to fit against the outer edge of the support rod 6. When the surge arrester body 7 shakes, the surge arrester body 7 causes the clamping plate 27 to move through the rubber pad 28. The clamping plate 27 then causes the outer edge of the sliding cylinder 22 to slide in the inner wall of the outer cylinder 21. The sliding cylinder 22 then causes the outer edge of the magnet ring 25 to slide in the inner wall of the coil 26. The coil 26 then generates electromagnetic damping on the magnet ring 25, thereby assisting the surge arrester body 7 in reducing vibration.
