Outburst-preventing reverse air door pneumatic interlocking closing device
The invention discloses an outburst-preventing reverse air door pneumatic interlocking closing device, and relates to the technical field of coal mine air doors. The device comprises a door frame, anair door and a wind sensing electric fan, wherein the top of one side surface of the air door is fixedly connected with an arc guide rod. By arranging the wind sensing electric fan, during blasting ina mine or a gas outburst accident, if the air door is not closed, air passing through the door frame can be used for driving fan blades in the wind sensing electric fan to rotate, so that a rotatingshaft rotates, a pressing rod is pulled through a pull rope, after a limiting ejector rod is bent, the air door is automatically closed under the action of door closing springs, meanwhile, by arranging the arc guide rod, when the air door is opened, a rotating plate can be jacked tightly through the limiting ejector rod, so that the position of the air door is fixed through the arc guide rod, theair door is kept stable when being opened, moreover, the door closing springs always provide door closing force for the air door, so that the air door is kept in the closed state.
本发明公开了一种防突反向风门风动连锁关闭装置，涉及煤矿风门技术领域，包括门框、风门和感风电扇，所述风门的一侧面顶部固定连接有圆弧导杆。本发明通过设置感风电扇，在矿内放炮或者发生瓦斯突出事故的时候，如果风门没有关闭，能够利用通过门框的空气带动感风电扇内部扇叶转动，使转动轴转动利用拉绳将压杆拉动，从而将限位顶杆折弯之后使风门在关门弹簧的作用下实现自动关闭，通过设置圆弧导杆，在将风门打开的时候能够利用限位顶杆将转动板顶紧，使圆弧导杆将风门的位置固定，使风门在打开的时候保持稳定，并且关门弹簧始终提供给风门关门的力，使风门在关门状态下保持状态。
