Description

Technical Field

[0001] The utility model relates to the technical field of lightning arresters, in particular to an earthquake-resistant lightning arrester. Background Technique

[0002] Lightning arresters are usually installed near the protected equipment. When there is lightning or other abnormal high voltages, the lightning arresters will respond in a timely manner, release the excessive voltage through their own characteristics, and guide the strong current to the ground, thus effectively protecting electrical equipment from overvoltage damage and ensuring the normal operation of the system and the safety and stability of the equipment. It plays a crucial role in many fields such as electric power, communication, and railway.

[0003] For existing lightning arresters, in special cases, the electric pole will vibrate and shake, causing the lightning arrester above to vibrate. Most lightning arresters are directly installed inside above the inductor without a shock-absorbing structure, resulting in the possibility of detaching from the top of the electric pole and falling down after being subjected to severe vibration. At the same time, installing lightning arresters is a high-altitude operation, and traditional lightning arresters are cumbersome to install, resulting in an increase in the operation time and further increasing the risk of installers.

[0009] As a preferred technical solution of the present utility model, the connecting plate is parallel to the fixing piece, and the inner wall size of the connecting plate is adapted to the size of the fixing piece.

[0010] As a preferred technical solution of the present utility model, the twisting head, the threaded rod, and the fixing piece form a flipping assembly, and the number of the flipping assemblies is four. Two of the four flipping assemblies form a group and are symmetrically arranged on both sides of the fixing seat, and the twisting heads of each group face in opposite directions.

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

[0012] 1. When the lightning arrester body is tilted due to vibration, the buffer seat is driven to tilt on the top of the partition plate, so that the connecting block moves upward. Further, the connecting block drives one end of the connecting rod to move upward.

At this time, the connecting plate is parallel to the fixing piece. The twisting head is rotated, and the twisting head drives the threaded rod to rotate, so that the threaded rod drives the fixing piece to move towards the inner wall of the connecting plate. Further, a connection relationship is generated between the fixing piece and the inner wall of the connecting plate.

[0023] In a preferred embodiment, the number of the sliders 9 is two, and the two sliders 9 are respectively arranged at both ends of the slide rail 7. In the above structure, with the two sliders 9 at both ends of the slide rail 7, the springs 8 arranged outside the slide rail 7 push the sliders 9 towards both sides of the fixed seat 1, so that the two sliders 9 are attached to both sides of the inner wall of the fixed seat 1.

[0024] In a preferred embodiment, an extension block is arranged on one side of the slider 9 close to the connecting rod 10, and one end of the connecting rod 10 far from the connecting block 11 is rotatably connected to the extension block. In the above structure, when the lightning arrester body 4 is tilted due to vibration, it drives the buffer seat 3 to tilt on the top of the partition plate 6, so that the connecting block 11 at the bottom of the buffer seat 3 moves upward.

At this time, the connecting plate 2 is parallel to the fixing piece 14. Rotate the twisting head 12, and the twisting head 12 drives the threaded rod 13 to rotate, so that the threaded rod 13 drives the fixing piece 14 to move towards the inner wall of the connecting plate 2, thereby making the fixing piece 14 have a connection relationship with the inner wall of the connecting plate 2. At this time, the fixed seat 1 is fixed through the fixing piece 14 and the connecting plate 2, and then the fixing plate 5 is fixed. Insert the bolt 17 from the bottom of the reserved hole of the mounting rack and rotate it to fix the whole device above the mounting rack through its fixation with the threaded barrel 15, so that it will not slide. When the device receives vibration, the lightning arrester body 4 is tilted due to the vibration, driving the buffer seat 3 to tilt on the top of the partition plate 6, so that the connecting block 11 at the bottom of the buffer seat 3 moves upward. Furthermore, the connecting block 11 at the bottom of the buffer seat 3 and one end of the moving connecting rod 10 move upward.
