Through the arrangement of the protective cover 7, connecting plates 29, first bolts 30, first threaded groove 31, first sealing gasket 32 ​​and sealing groove 33, the protective cover 7 can be installed and disassembled. After a period of use, the protective cover 7 can be disassembled and the first dustproof net 8 on it can be cleaned. The arrangement of the first sealing gasket 32 ​​and sealing groove 33 improves the sealing performance of the connection.

[0032] Multiple second bolts 34 are provided through the second dustproof net 11. The inner wall of the placement groove 10 is provided with a second threaded groove 35 that cooperates with the second bolts 34. A second sealing gasket 36 is fixedly connected to the inner wall of the placement groove 10. Through the arrangement of the placement groove 10, the second dustproof net 11, the second bolts 34, the second threaded groove 35 and the second sealing gasket 36, the second dustproof net 11 can be installed and disassembled. After a period of use, it can be removed and cleaned. The second sealing gasket 36 can improve the sealing of the connection.

[0033] Mounting holes 37 are provided at the four corners of the upper surface of the base plate 1. The base plate 1 can be fixed at the installation position by setting the mounting holes 37 and cooperating with the mounting bolts.

[0034] The T-shaped limiting plate 4 has an inclined surface.

[0035] Working Principle: In use, the base plate 1 can be fixed in the installation position by setting the mounting hole 37 and cooperating with the mounting bolts. When fixing the main body 3 of the power converter, the T-shaped limiting plate 4 can be inserted into the T-shaped limiting groove 5. At the same time as the T-shaped limiting plate 4 is inserted, the fixing rod 16 in the fixing mechanism contacts a section of the inclined surface on the T-shaped limiting plate 4, causing the fixing rod 16 to retract and drive the moving plate 14 to move in the cavity 12. The movement of the moving plate 14 causes the spring 15 to contract and generate elastic deformation. When the fixing hole 18 on the T-shaped limiting plate 14 moves to the position corresponding to the fixing rod 16, the spring 15 restores its elastic deformation and drives the moving plate 14 to insert the fixing rod 16 into the fixing hole 18, thereby realizing the T-shaped limiting. The limiting position of plate 4 completes the self-locking fixation of the power converter body 3. When disassembly is required, two toggle plates 23 can be moved simultaneously. The toggle plates 23 drive the sliding rod 21 to move through the toggle rod 22, thereby allowing the moving plate 14 to drive the fixing rod 16 to disengage from the fixing hole 18, thus completing the disassembly. This is convenient, time-saving, and labor-saving, improving the work efficiency of the staff. Through the setting of cooling fan 6, protective cover 7, first dustproof net 8, opening 9, placement slot 10 and second dustproof net 11, the heat inside the power converter body 3 can be discharged. At the same time, outside air enters the power converter body 3 through opening 9, realizing air circulation and facilitating heat dissipation. In addition, the setting of first dustproof net 8 and second dustproof net 11 can filter dust in the air.
