Background art:
the mining explosion-proof electric actuator is widely applied to coal mine ventilation and water pump systems, is an important actuating mechanism in coal mine underground automatic control, and controls the closing of a valve. In the underground mining process of the coal mine, the air contains explosive mixtures, so that the danger of gas explosion can occur when the air meets high temperature or sparks with enough energy; a great deal of coal dust can be caused to fly in the excavation process, and when the coal dust is used as a large heat source, the danger of explosion can occur. These two types of explosions are associated, and generally cause coal dust explosion after gas explosion, and the damage caused by coal dust explosion is more serious. And the underground air humidity of the coal mine is relatively high, the water vapor of the coal mine has a corrosion effect, and the insulating property of the original electric material can be reduced due to the fact that coal dust continuously invades into the electric shell in the long-term operation process of the electric equipment, so that the electric breakdown phenomenon can be caused by serious people, and the underground electric equipment needs an explosion-proof design.
