Abstract

The invention discloses a coal mine gas outburst detection device. The coal mine gas outburst detection device comprises a placement block. The inner of the placement block is provided with a first placement cavity. A balloon is arranged in the first placement cavity. The balloon is filled with air at standard pressure. The device is convenient to install and is arranged on the top of a mine cablecar. Through the cyclic operation of the cable car, the gas emission cycle detection is carried out. The device can make up for the problems that an electronic detector cannot move and electronic parts are easy to malfunction. Through the number of fans blown by gas, the gas emission can be detected. Through the rotation speed of the fans blown by gas, the gas emission speed can be detected. Theinvention is provided with a wind power storage device. The coal mine gas outburst detection device solves the problem of distinguishing the fans blown by gas from fans blown by air. When the concentration of gas emission exceeds a certain value, a pressure block is pushed to detect the concentration through the expansion of the balloon, and a wall is marked by a spray gun. When the concentrationof gas emission exceeds a critical value, a alarm device can be sounded for emergency treatment.

Description

technical field [0001] The invention relates to mining devices, in particular to a coal mine gas outburst detection device. Background technique [0002] The occurrence rate of gas explosion is the highest in the process of coal mining. Gas explosion is highly destructive and sudden. Because gas is colorless, odorless, and difficult to detect, except for electronic detection devices, the staff cannot detect its existence. When local Gas buildup occurs when ventilators stop running, blower cylinders disconnect, or severe air leaks occur. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a coal mine gas outburst detection device, which solves the problem that the existing electronic detectors cannot detect the mine cycle, and performs mechanical detection on the gas outburst. [0004] The present invention is achieved through the following technical solutions. [0005] A coal mine gas outburst detection device of t...
