Mine underground roadway waterproof door self-adaptive loading protection device
The invention discloses a self-adaptive loading protection device for a waterproof door of a mine underground roadway, self-adaptive loading protection device chambers are symmetrically arranged on two sides of a downstream roadway of the waterproof door, and self-adaptive loading protection devices are arranged in the two self-adaptive loading protection device chambers. The water flow pressure of underground water inrush is used as the loading pressure of the self-adaptive loading protection device, the liquid inlet control valve and the one-way valve are used for adapting to the water flow pressure change, and the thrust required by the protection waterproof door is adjusted by utilizing the area change of the piston in the loading cylinder body. The waterproof door can effectively solve the problem that the waterproof door is easily pushed to be collapsed and damaged due to the fact that the pressure difference value of the two sides of an existing waterproof door is too large, and the important function of protecting the waterproof door is achieved.
本发明公开了一种矿山井下巷道防水门自适应加载保护装置，在防水门的下游巷道两侧，对称布置安装自适应加载保护装置硐室，两个自适应加载保护装置硐室均布置有自适应加载保护装置。以地下突水的水流压力作为自适应加载保护装置的加载压力，通过进液控制阀和单向阀适应水流压力变化，利用加载缸体内活塞面积改变，调整保护防水门所需的推力。本发明可以有效解决现有防水门两侧压力差值过大所导致的防水门容易推垮破坏的问题，实现保护防水门的重要作用。
