The fixing mechanism 2 includes a first limiting assembly 21, an adjusting assembly 22 and a second limiting assembly 23. The adjusting assembly 22 is horizontally arranged in the box body 12, and the adjusting assembly 22 and the second limiting assembly 23 are longitudinally arranged in the box body 12. The first limiting assembly 21 includes two clamping blocks 213, and the two clamping blocks 213 are respectively clamped with the first bottom plate 11 and the second bottom plate 14.

[0020] A fixing plate 216 is fixedly connected to the upper surface of the box body 12, and a first bidirectional screw 211 is rotatably connected to the fixing plate 216. The first bidirectional screw 211 penetrates the box body 12 and is rotatably connected to the mounting plate 13 at the bottom. The upper and lower ends of the first bidirectional screw 211 are rotatably mounted on the fixing plate 216 and the mounting plate 13 respectively.

[0021] The first two-way screw rod 211 has first screw sleeves 212 threadedly sleeved on the upper and lower ends of the rod, and the two first screw sleeves 212 are respectively fixedly connected to the two clamping blocks 213, and the two clamping blocks 213 are respectively clamped on one end of the first bottom plate 11 and the second bottom plate 14. A driving gear 214 and a worm gear 215 are fixedly sleeved on the middle rod of the first two-way screw rod 211. The adjustment component 22 includes a fixed block 221 and a rotating shaft 222. The fixed block 221 is fixedly connected to the inside of the box body 12. One end of the rotating shaft 222 is rotatably installed in the box body 12, and the other end passes through the fixed block 221 and a limiting screw sleeve 224 is sleeved on the shaft body, and the limiting screw sleeve 224 is fixedly installed on the fixed block 221. A fastening nut 225 is threadedly sleeved on the limiting screw sleeve 224, a worm 223 is fixedly sleeved on the middle shaft of the fixed block 221, the worm 223 is meshingly connected with the worm wheel 215, the second limiting assembly 23 includes a second bidirectional screw 231, the middle part of the second bidirectional screw 231 is rotatably installed in the box body 12, a driven gear 232 is fixedly sleeved on the middle part of the rod body of the second bidirectional screw 231, the driven gear 232 is meshingly connected with the driving gear 214, second screw sleeves 233 are threadedly sleeved on the rod bodies at both ends of the second bidirectional screw 231, and baffles 234 are fixedly connected to the two second screw sleeves 233, and the two baffles 234 slide through the upper and lower ends of the box body 12 respectively.

[0022] Specifically, the two clamping blocks 213 are slidably connected to the upper and lower ends of the box body 12 respectively. When in use, the worm 223 is driven to rotate synchronously by rotating the rotating shaft 222, and the worm 223 drives the worm wheel 215 to rotate, thereby driving the first bidirectional screw 211 and the driving gear 214 to rotate synchronously. The first bidirectional screw 211 drives the first screw sleeves 212 at both ends to move outward at the same time, so that the clamping blocks 213 slide along the inner wall of the channel inside the box body 12 until most of them extend out of the box body 12, and the second bottom plate 14 and the first bottom plate 11 are correspondingly plugged into the clamping blocks 213, and then the rotating shaft 222 is rotated in the opposite direction to move the two clamping blocks 213 inward, so that the second bottom plate 14 and the first bottom plate 11 are 4 and the first bottom plate 11 are pressed against the upper and lower surfaces of the box body 12. During this process, the driving gear 214 drives the driven gear 232 to rotate, so that the second bidirectional screw 231 rotates. Through the threaded cooperation between the second bidirectional screw 231 and the second screw sleeve 233, the second screw sleeves 233 at both ends simultaneously drive the baffle 234 to move in the direction away from each other, so that the baffle 234 extends outward from the limiting groove and blocks one side of the second bottom plate 14 and the first bottom plate 11, which can avoid sliding at the connection between the first bottom plate 11 and the second bottom plate 14, improve the stability of the installation of the first bottom plate 11 and the second bottom plate 14, and thus improve the stability of the arrester body 1.

[0023] In the present application, the first base plate 11 and the second base plate 14 can be fixed synchronously and in multiple directions only by rotating the rotating shaft 222, thereby improving the convenience of operation and the stability of equipment installation. The meshing connection between the worm 223 and the worm wheel 215 can prevent the first bidirectional screw 211 and the second bidirectional screw 231 from reversing, thereby ensuring the tightness and reliability of the connection. By tightening the fastening nut 225, one end of the limiting screw sleeve 224 is tightened inward, and the rotating shaft 222 is firmly fixed to prevent the rotating shaft 222 from rotating, thereby effectively improving the stability of each component.

[0024] A telescopic rod 32 is fixedly installed in the middle of the support frame 31, and a spring 38 is sleeved on the upper end of the telescopic rod 32. The upper and lower ends of the spring 38 are respectively fixedly connected to the lifting plate 33 and the support frame 31. A number of rollers 37 are installed on the lifting plate 33. One end of the support block 34 is fixedly connected to the support rod 341. The bottom of the lifting plate 33 and the support rod 341 are respectively provided with a movable component 36 and a linkage component 35. The movable component 36 includes a rack 361 and a limit bar 362. The rack 361 and the limit bar 362 are fixedly connected to one side of the lower end of the lifting plate 33. One side of the rack 361 is meshed with a second gear 363. The second gear 363 is rotatably installed inside the support frame 31. The linkage component 35 includes a second bevel tooth 351 and a first bevel tooth 352. The second bevel tooth 351 and the first bevel tooth 352 are respectively coaxially fixedly connected to the bottom of the support rod 341 and one side of the second gear 363. The second bevel tooth 351 is meshed with the first bevel tooth 352.

[0025] In the present application, in order to solve the problem that the arrester body 1 is heavy and it is inconvenient to plug the first base plate 11 and the second base plate 14 into the clamping block 213 correspondingly during installation, a support mechanism 3 is provided on one side of the mounting plate 13. When in use, the first base plate 11 is placed on a plurality of rollers 37, and the lifting plate 33 is pressed downward by the deadweight of the arrester body 1. The lifting plate 33 drives the rack 361 to move synchronously, and the rack 361 drives the second gear 363 and the first bevel gear 352 to rotate, and the first bevel gear 352 drives the second bevel gear 351 and the support rod 341 to rotate, and the support rod 341 drives the support block 34 is rotated to rotate the support block 34 to the top of the lifting plate 33, and the bottom of the lightning arrester body 1 is relatively moved to the opening of the support block 34, and then the lightning arrester body 1 is pushed along the surface of the lifting plate 33, so that the first bottom plate 11 and the second bottom plate 14 are close to the clamping block 213 at the same time until they are plugged into the clamping block 213. This arrangement can reduce the strength of the lightning arrester body 1 during installation, and facilitates the alignment of the first bottom plate 11 and the second bottom plate 14. At the same time, by supporting the second bottom plate 14 through the support block 34, the stability of the second bottom plate 14 and the lightning arrester body 1 can be further improved.

[0026] like Figure 1-Figure 9 As shown, a method for using a power system lightning arrester for distribution network planning provided by an embodiment of the present invention includes the following steps: S1: Open the side cover of the box body 12, and use the adjustment component 22 to drive the first limit component 21 and the second limit component 23 to move, so that the two clamping blocks 213 are respectively moved out from the upper and lower ends of the box body 12, and the two ends of the second limit component 23 are moved inward into the box body 12; S2: Place the first bottom plate 11 on a plurality of rollers 37, support the arrester body 1 through the rollers 37, move the second bottom plate 14 upward to make it located above the box body 12, the arrester descends under the action of gravity and the lifting plate 33 is pressed downward, and the lifting plate 33 drives the support block 34 to rotate during the downward movement, and the support block 34 rotates to a horizontal state, so that the bottom of the arrester body 1 enters the inside of the support block 34 from the opening of the support block 34, and the second bottom plate 14 is located on the upper surface of the support block 34, and then push the arrester body 1 toward the box body 12, so that the first bottom plate 11 and the second bottom plate 14 are respectively plugged into the two clamping blocks 213, and the support block 34 is supported under the second bottom plate 14; S3: Rotate the adjusting component 22 in the opposite direction to rotate the first limiting component 21 and the second limiting component 23 in the opposite direction, and the two clamping blocks 213 move in the direction of approaching each other to press the first bottom plate 11 and the second bottom plate 14 tightly, and the two ends of the second limiting component 23 move in the direction of moving away from each other and extend the box body 12 outward to block one side of the first bottom plate 11 and the second bottom plate 14, thereby limiting the first bottom plate 11 and the second bottom plate 14 and completing the installation of the arrester body 1.

[0027] To sum up: this kind of power system lightning arrester for distribution network planning can achieve synchronous and multi-directional fixation of the second base plate 14 and the first base plate 11 only by rotating the rotating shaft 222, thereby improving the convenience of operation and the stability of equipment installation. The worm 223 is meshed with the worm wheel 215 to prevent the first bidirectional screw 211 and the second bidirectional screw 231 from reversing, thereby ensuring the tightness and reliability of the connection. By tightening the fastening nut 225, one end of the limiting screw sleeve 224 is tightened inward, and the rotating shaft 222 is firmly fixed to prevent the rotating shaft 222 from rotating, thereby effectively improving the stability of each component. By setting up the supporting mechanism 3, the lightning arrester body 1 can be supported when it is installed, reducing the workload of the first base plate 11 and the second base plate 14 when installing and aligning. During the placement of the lightning arrester body 1, the lifting plate 33 moves downward, driving the support block 34 to rotate, and supporting the second base plate 14 through the support block 34, further improving the installation stability of the second base plate 14 and the lightning arrester body 1.

[0028] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
