Problems solved by technology

[0002] In electrical engineering, it not only needs a good design layout, but also needs to set up a reasonable control device for control. At the same time, because the control components are set in the control cabinet, the protection of the components is realized. However, most control cabinets are set The environment is relatively harsh. If reasonable anti-corrosion or isolation measures are not provided, it will cause corrosion and cabinet damage, which will inevitably affect the use effect of the control components; a double-sealed anti-corrosion and heat preservation is disclosed in the authorized announcement number CN 202565622 U The control cabinet includes a cabinet body, a back panel and a cabinet door, wherein the cabinet door has two layers and is pivotally connected with the cabinet body respectively, and the back panel and the cabinet body are detachably connected
However, its mass is relatively large, and the sealing effect is still not good
[0003] Application publication number CN 106785964 A discloses an outdoor waterproof and anti-corrosion intelligent power control cabinet, which includes a cabinet body in which electric meter components are installed; on the top plate of the cabinet body, a vertical rod is used to fix and support a rain shield ;A windmill is installed between the top of the cabinet and the rain shield, and a transmission shaft is installed at the rotating shaft of the windmill, and the transmission shaft extends into the interior of the cabinet; equidistant installation on the transmission shaft There are driving wheels, each of which is engaged with the transmission shaft; suction fan blades are matched and installed on the driving wheels; the suction fan blades are placed in the suction tube, and one end of the suction tube extends and passes through the Pass through one side wall of the cabinet body, the other end is connected to the spiral pipe, and a filter screen is fixed close to the end of each spiral pipe; an air outlet is opened on the other side wall of the cabinet body; but the structure of the control cabinet is complicated, The quality is heavy, and there is no balance module, which is prone to the phenomenon of the cabinet toppling over
