[0046] The clamping assembly 2 comprises a first clamping component 210, an adjusting component 220 and a second clamping component 230; the first clamping component 210 and the second clamping component 230 clamp two ends of the lightning arrester respectively, the adjusting component 220 is connected with the first clamping component 210, and the first clamping component 210 is clamped or loosened on the two ends of the lightning arrester through cooperation of the adjusting component 220 and the second clamping component 230; through the action of the adjusting component, the first clamping component can be driven to produce the clamping or loosening action relative to the second clamping component, so that the installation, disassembly and maintenance operation of the lightning arrester are facilitated, and the flexibility and reliability of the operation are improved.

[0047] The positioning assembly 3 comprises a first positioning component 310 and a second positioning component 320;

[0048] The first positioning component 310 drives the lightning arrester to move through the installation rack 1, drives the installation rack to move as a whole through the pushing mode, so that the translation adjustment of the lightning arrester in a preset direction is realized; the second positioning component 320 adjusts the installation angle of the installation rack 1 and the lightning arrester through rotation, drives the installation rack and the lightning arrester to produce an angle change as a whole through rotation, so that the installation angle adjustment of the lightning arrester is realized. Through the above structure design, the position and angle of the lightning arrester can be flexibly adjusted under different installation environments and space conditions, so that the lightning arrester can be accurately installed according to the engineering needs, and the requirements of electrical safety and mechanical stability are met.

[0049] Further, in the embodiment, Figure 3 is a structure schematic view of the installation rack and the clamping assembly of one embodiment of the present application; Figure 4 is a structure schematic view of the positioning assembly of one embodiment of the present application; Figure 5 is a structure schematic view of the clamping assembly of one embodiment of the present application; as Figure 3 、 Figure 4 and Figure 5 As shown in the drawings, the first clamping component 210 comprises a positioning sleeve 211, a first lead screw 212 and a limiting block 213; one end of the positioning sleeve 211 is connected with the installation rack 1, the positioning sleeve 211 is provided with a positioning installation groove, the limiting block 213 is arranged in the positioning installation groove, the first lead screw 212 is threadedly connected with the positioning sleeve 211, and the first lead screw 212 is abutted with the lightning arrester through rotation. The limiting block 213 is arranged in a pair and located on both sides in the positioning installation groove, and is used for clamping the lightning arrester from both sides.

[0050] One end of the positioning sleeve 211 is fixedly connected with the mounting frame 1, forming a mounting base of the first clamping component 210. A positioning installation groove is formed in the interior of the positioning sleeve 211, which is used for installing and limiting the movement direction of the limiting block 213, so as to ensure that the limiting block 213 can always maintain the stable support and limiting effect on the lightning arrester during the working process. The limiting block 213 is arranged in pairs and arranged on both sides of the positioning installation groove, and the opposite arrangement can clasp the lightning arrester from both sides. When the lightning arrester is placed in the installation position, the limiting blocks 213 on both sides can effectively abut against the outer surface of the lightning arrester, realizing the clamping and limiting of the lightning arrester in the radial direction, preventing the lightning arrester from being displaced or shaken in the mounting frame 1. In order to improve the safety and adaptability, the contact surface of the limiting block 213 can be made into an arc surface to adapt to the cylindrical outer wall structure of the lightning arrester, so as to ensure uniform stress and enhance clamping stability. In addition, the contact surface of the limiting block 213 can also be coated with a non-slip rubber layer or an insulating buffer layer to increase the friction and play a buffering protection role, preventing the lightning arrester shell from being scratched or damaged due to hard extrusion. The first screw rod 212 is threadedly connected with the positioning sleeve 211, and the screw rod 212 can move in and out along the radial direction of the positioning sleeve 211. When the first screw rod 212 rotates, the front end gradually extends into the positioning sleeve 211 and contacts the outer wall of the lightning arrester, so as to exert a clamping force on the lightning arrester. As the screw rod 212 continues to rotate, the lightning arrester will be further pressed between the two limiting blocks 213, realizing limiting and fixing; when the screw rod 212 rotates out, the clamping force gradually decreases until it is released, so as to facilitate the disassembly or reinstallation of the lightning arrester. Further, the front end of the first screw rod 212 can be processed into a spherical or arc-shaped end structure to adapt to the curved surface of the limiting block 213 shell, ensuring closer contact and avoiding local damage caused by pointwise stress. The screw rod 212 can be made of stainless steel or alloy steel to improve wear resistance and corrosion resistance, ensuring long-term use reliability in outdoor high-humidity and strong electric field environments.

[0051] The first clamping component 210 can realize stable clamping of the lightning arrester during installation, and in combination with the radial clamping of the limiting block 213 and the axial pressing action of the first screw rod 212, effectively prevents the lightning arrester from loosening or displacement in the mounting frame 1, significantly improves the safety and reliability of the mounting device, and also facilitates the quick installation and disassembly of the lightning arrester by the operator. The second clamping component 230 has the same structure as the first clamping component 210.

[0054] The rotating component comprises a second lead screw 222 and a sleeve 223, one end of the sleeve 223 is connected with the mounting frame 1, one end of the second lead screw 222 is sleeved in the sleeve 223, the second lead screw 222 is threadedly connected with the sleeve 223, the second lead screw 222 is connected with the sliding block 221 through the mounting hole, and the sliding block 221 is driven to ascend and descend through rotation of the second lead screw 222, thereby driving the first clamping component 210 to move relative to the second clamping component 230, and clamping or loosening the lightning arrester at both ends. When the operator rotates the second lead screw 222, the threaded action makes the second lead screw 222 move in the axial direction, thereby driving the sliding block 221 to ascend and descend. Since the sliding block 221 is fixedly connected with the positioning sleeve 211 of the first clamping component 210, the first clamping component 210 moves along the direction of the mounting rod 110 along with the ascending and descending of the sliding block 221, thereby realizing the approaching or moving away action relative to the second clamping component 230.

[0055] Further, in the embodiment, the positioning assembly 3 comprises a horizontal plate 330, the first positioning component 310 and the second positioning component 320 are respectively connected with the horizontal plate 330; the first positioning component 310 is connected with the mounting frame 1, and the second positioning component 320 drives the mounting frame 1 to rotate through the horizontal plate 330 and the first positioning component 310.

The positioning sliding block 312 can make linear sliding motion along the sliding block slot, the first positioning elastic member keeps the positioning sliding block 312 and the slot bottom in pre-tight connection through elastic force, after the clamping state is released, the first positioning elastic member generates elastic force to push the sliding block 312 to slide out of the slot body, with the movement of the positioning sliding block 312, the end portion thereof contacts the mounting rack 1 and applies pushing force, so as to drive the mounting rack 1 to move along the predetermined direction, and the adjustment of the installation position of the lightning arrester is realized. The first positioning elastic member can be made of a coil spring, a torsion spring or other elastic materials, which can provide sufficient pushing force to ensure that the sliding block 312 moves smoothly under the action of external force.
