Abstract

The invention provides a water-permeation-proof outburst-proof buffer device. The device comprises a fixing mechanism, a buffering door curtain and a triggering mechanism, the fixing mechanism is fixed to the top end of a roadway, the buffering door curtain is installed on the fixing mechanism, the buffering door curtain is rolled from the bottom end to the top end and is fixed through the fixingmechanism, the triggering mechanism is connected with the fixing mechanism, and the triggering mechanism is fixed to the top end of the roadway; and the buffering door curtain comprises a plurality ofcurtain bodies, a pocket is arranged at the lower portion of each curtain body, and the length of each curtain body is larger than the height of the roadway. The problem that an outburst prevention air door is far away and cannot respond quickly is solved, the protection performance is improved, and the escape time is prolonged.

Description

technical field [0001] The invention relates to the field of underground protection devices in coal mines, in particular to an anti-water penetration and anti-burst buffer device. Background technique [0002] At present, the outburst prevention devices used in coal mines are mainly anti-outrush doors. Once the anti-outrush doors are constructed, they will be permanent dampers. The group damper is automatically closed by the thrust of the shock wave, completely isolating the affected area. With the extension of the excavation surface, the roadway distance increases, and the anti-draft door is far away, which cannot respond quickly and reduces the safety of protection. Contents of the invention [0003] In order to solve the problem in the prior art that the anti-sudden door is far away and cannot respond quickly, the present invention proposes a waterproof and anti-sudden buffer device. [0004] Technical scheme of the present invention is realized like this: [0005] A...
