Detailed Description
An embodiment of the present invention is further described with reference to the accompanying drawings:
the utility model discloses a simple and easy colliery tunnel defogging device mainly comprises liquid nitrogen generating device (7), well accuse case (6), visibility monitor (4), personnel inductor (5), third metal collapsible tube (3), second metal collapsible tube (2) and first metal collapsible tube (1). The liquid nitrogen generating device (7) is connected with a second metal hose (2) arranged in a coal mine roadway (11), and the first metal hose (1) is hung above the coal mine roadway (11) by a hanging chain (10) and is respectively connected with the second metal hose (2) and a third metal hose (3). And nozzles (9) are uniformly distributed on the third metal hose (3). The visibility monitor (4) and the personnel sensor (5) are both arranged in a coal mine roadway (11) and are respectively connected with the central control box (6). The central control box (6) controls the opening and closing of an electromagnetic valve (8) on the liquid nitrogen generating device (7) according to electric signals returned by the visibility monitor (4) and the personnel sensor (5).
The working process is as follows:
a: hanging third metal hoses (3) at the top of the coal mine tunnel (11) and 1m away from the two sides respectively, wherein the distance reserved at the two sides is a pedestrian path;
b: a nozzle (9) is arranged right below the hanging part of the first metal hose (1), and the nozzles (9) are respectively arranged on one side of the third metal hose (3) towards the coal mine roadway (11);
