| titleOfInvention | Coal mine electric explosion-proof box |
| abstract | The utility model provides a colliery electrical explosion-proof box relates to explosion-proof field. This colliery electrical explosion-proof box, including box and vacuum pump, vacuum pump fixed mounting is at the top of box, and the vacuum pump has pressure switch with the internal connection of box and link up, the interior diapire fixed mounting of box, and the opening has been seted up in the front of box, and the edge of opening is seted up flutedly, and the front left side fixed mounting of box has the articulated shaft, and the box articulates through the articulated shaft has the door plant, and the back fixed mounting of door plant has the closing plate, and the inside of door plant is inlayed and is had the thread bush. This colliery electrical explosion-proof box discharges the air in the box through the vacuum pump, through the effect of the removal wall in the pressure switch pressurized, contacts through anodal touch panel and negative pole touch panel when the inside pressure of box increases and starts the effect that the vacuum pump can continue to exhaust and reach the state that is in the vacuum all the time, has solved among the prior art in the box can not be in the vacuum state always. |
