Problems solved by technology

[0002] Cheji Coal Mine is a coal and gas outburst mine. According to the outburst prevention regulations, the air intake side damper of the excavation face of the outburst mine shall be managed according to the outburst prevention. The anti-headwind device of the slip hole in the damper wall uses a simple leather or iron plate, which is easily damaged after long-term use, has poor flexibility, and the device is not closed tightly, resulting in air leakage

Embodiment Construction

[0015] As attached figure 1 As shown, an anti-wind device for Liuzidong includes an anti-upwind device 1 and a seal door 2 for Liuzidong; the anti-upwind device 1 includes a metal plate 1-1, and the metal plate 1-1 is formed by a rope 1- 2 Suspended under the roof 4 of the roadway to maintain a vertical state; the top side of the Liuzidong 3 is hinged with a Liuzidong sealing door 2; the outer side of the Liuzidong sealing door 2 and the bottom of the metal plate 1-1 are correspondingly provided with connections Device; under normal conditions, the Liuzidong sealing door 2 is connected to the metal plate 1-1 through the connecting device, and kept in a horizontally open state, the Liuzidong 3 normally enters the wind; when the gas outburst, the wind flow reverses quickly and the wind flow hits the metal plate 1- 1. Separate the connecting device, and the Liuzidong sealing door 2 will close the Liuzidong 3 by gravity.

Abstract

The invention relates to an anti-headwind device for scraper-trough conveyer holes. The device includes an anti-headwind touch device and a scraper-trough conveyer hole sealing door; the anti-headwindtouch device includes a metal plate; the metal plate is hung under a tunnel top board through lifting ropes to keep a plumb state; the top edge of a scraper-trough conveyer hole is in hinged joint with the scraper-trough conveyer hole sealing door; the outer side surface of the scraper-trough conveyer hole sealing door and the bottom of the metal plate are correspondingly provided with connectingdevices; under a normal state, the scraper-trough conveyer hole sealing door is connected to the metal plate through the connecting devices, so that a horizontal opening state can be maintained, andthe normal air intake of the scraper-trough conveyer hole can be realized; and when gas outburst occurs, wind current can be rapidly reversed to hit the metal plate, so that the connecting devices canbe separated, and the scraper-trough conveyer hole sealing door can fall down to close the scraper-trough conveyer hole under gravity.

Description

Technical field [0001] The invention relates to mine facilities, in particular to an anti-wind device for Liuzidong. Background technique [0002] Cheji Coal Mine is a coal and gas outburst mine. According to the outburst prevention regulations, the air inlet side damper of the excavation face of the outburst mine shall be managed in accordance with outburst prevention management. The wind gate liuzi tunnel shall be equipped with an anti-upwind device. The previous anti-upwind device has been used before. The anti-wind device for the liuzi hole of the damper wall uses simple leather or iron plate, which is easy to be damaged after long-term use, has poor flexibility, and the device is not tightly closed, causing air leakage. Summary of the invention [0003] In order to solve the above technical problems, the present invention provides an anti-wind device for Liuzidong, which is safe and reliable and can realize linkage. [0004] The present invention is achieved through the follow...
