In order to achieve the purpose, the automatic door opening and closing device for the high-voltage cabinet comprises a cabinet body and an air cylinder, wherein the cabinet body is hinged with a cabinet door;
the air cylinder comprises a cylinder barrel, a piston is sleeved in the cylinder barrel, the right side of the piston is connected with a spring, the right end of the spring is connected with the cylinder barrel, the left side of the piston is provided with a piston rod, the piston rod penetrates through the left side of the cylinder barrel, and the left end of the cylinder barrel is communicated with an air pipe;
the left end of the piston rod is hinged with the cabinet door, and the right end of the cylinder barrel is hinged with the cabinet body.
Furthermore, a piston ring is arranged at the contact part of the piston and the cylinder barrel.
Further, a rubber pad is arranged at the contact part of the cabinet door and the cabinet body.
Further, the air cylinder is controlled by a wireless remote controller.
Compared with the prior art, the utility model has the beneficial effects that:
piston in the cylinder promotes to the left under the effect of spring, and the piston promotes the piston rod left, and the piston rod promotes the cabinet door and lets cabinet door and cabinet body be the closure state, when needing to open the cabinet door and inspect, and remote control high-pressure gas passes through the trachea and gets into the cylinder left end, and high-pressure gas promotes the piston and moves right, and the piston drives the piston rod and moves right, and the piston rod stimulates the cabinet door and lets the cabinet door overturn for the cabinet body to this opens the cabinet door.
To sum up, adopt this kind of high-voltage board automatic switch door device, realized not needing artifical contact high-voltage board also can realize opening and closing of high-voltage board cabinet door, no longer need the outage to carry out a preliminary inspection to the electrical component in the cabinet to the cost of overhaul has been reduced.
