Preferably, the waterproof and dustproof plate is fixed on the inner wall of the locking cavity of the locking block through the mounting block, and the locking block is fixed on the left inner wall and the right inner wall of the box body. This scheme has improved the installation stability ability of waterproof dust guard through installation piece and latch segment to the convenience of dismantling and maintaining of waterproof dust guard can be improved.

Preferably, the box body comprises a sealing layer which is fixed at the front end of the inner wall of the box body and is tightly attached to the inner wall of the box door. This scheme can increase the leakproofness of chamber door and box through the sealing layer, and then reduces external moisture or dust and causes the influence to internal plant to influence the life of electric cabinet.

Preferably, the sealing and fixing assembly comprises a connecting block and a fixing block, the fixing block is fixed on the inner wall of the box body, and the connecting block is fixed on the rear surface of the sealing layer; the connecting block is tightly attached to the mounting cavity between the fixing block and the box body. This scheme connecting block and fixed block through sealed fixed subassembly can improve the installation stability of sealing layer, can increase the convenience of the dismantlement maintenance of sealing layer simultaneously.

Has the advantages that: after the structure of the utility model is adopted, because the structure is provided with the vent holes and the waterproof dustproof plate, the heat dissipation effect of the electric cabinet is increased through the vent holes at the bottom, and stronger waterproof effect can be realized; and the first dustproof net, the drying layer, the water absorption layer and the second dustproof net of the waterproof dustproof plate can be used for isolating dust and absorbing water for two times for ventilating and radiating gas, so that the waterproof and dustproof effects of the electric cabinet are further improved.
