The left plug block 4 and the right plug block 5 are fixedly arranged on the left and right sides of the grid plate 3. The left partition plate 1 and the right partition plate 2 are respectively provided with a plurality of left slots 6 and right slots 7. The left slots 6 and the right slots 7 are evenly arranged in the longitudinal direction. The mounting assembly includes a base 8, a plurality of auxiliary plates 9 fixedly arranged above the base 8, a fixing plate 10 located at the front and rear sides of the auxiliary plate 9, and a plurality of screws 11. The auxiliary plates 9 are evenly arranged in the longitudinal direction. The auxiliary plates 9 and the adjacent auxiliary plates 9 are fixedly arranged in the longitudinal direction. A plurality of gaps 12 are formed between the plates 9, and the width of the gaps 12 is equal to the thickness of the grid plate 3. A positioning block 13 is fixedly provided under the right partition plate 2, and a positioning groove 14 is provided on the top wall of the base 8 and is located on the right side of the auxiliary plate 9. After the positioning block 13 is inserted into the positioning groove 14, the right partition plate 2 is contacted and connected with the auxiliary plate 9, and the right slot 7 coincides with the position of the gap 12. After the grid plate 3 is inserted into the gap 12, the right insert block 5 is inserted into the right slot 7 and is contacted and connected with the right partition plate 2, and the left insert block 4 is inserted into the left slot 6 and is contacted and connected with the left partition plate 1. The left partition plate 1 and the right partition plate 2 are fixedly connected by a fixing plate 10 and a screw 11. When the arc extinguishing cover needs to be assembled, first insert the positioning block 13 into the positioning groove 14 so that the right partition plate 2 is in contact with the auxiliary plate 9, and then insert the grid plate 3 into the gap 12. Since the width of the gap 12 is equal to the thickness of the grid plate 3, the grid plate 3 will not shake at will inside the gap 12, which plays a positioning role. Then insert the sliding block 15 into the sliding groove 26 and slide it with the base 8, push the left partition plate 1 to the right to move it to the right, and after the left partition plate 1 is in contact with the grid plate 3 and connected, the left plug block 4 is inserted into the left slot 6 and is in contact with the left partition plate 1. Continue to push the left partition plate 1 to the right to move the left partition plate 1 and the grid plate 3 to the right. After the grid plate 3 is in contact with the right partition plate 2 and connected, the right plug block 5 is inserted into the right slot 7 and is in contact with the right partition plate 2. Since the position of the right slot 7 coincides with the gap 12, the right plug block 5 can be directly inserted into the right slot 7 without aligning them one by one, which improves the installation efficiency. Finally, the left partition plate 1 and the right partition plate 2 is inserted into the fixing groove 17 and fixedly connected with the fixing plate 10 by the screws 11, so that the assembly of the arc extinguishing hood is completed. After the arc extinguishing hood is removed from the base 8, the assembly of the next arc extinguishing hood can be carried out. Since the hot riveting process is omitted, the installation efficiency is improved; when the surface of the grid sheet 3 is rusted or carbon deposited and needs to be removed for maintenance, the screws 11 are unscrewed from the fixing plate 10, and then the fixing plate 10 is separated from the left partition 1 and the right partition 2, and then the left partition 1 and the right partition 2 are separated from the grid sheet 3, so that the grid sheet 3 can be directly repaired, which plays a role in facilitating the disassembly of the arc extinguishing hood for maintenance of the grid sheet 3; In summary, the utility model has the beneficial effects of improving the installation efficiency of the arc extinguishing hood and facilitating the disassembly of the arc extinguishing hood for maintenance, and solves the problem that the hot riveting process has high connection strength and is difficult to disassemble after the connection is completed, resulting in inconvenience in disassembling and assembling the arc extinguishing hood, and the problem that it is inconvenient to repair the arc extinguishing hood.
