Embodiment Construction

[0014] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0015] Such as figure 1 , figure 2 As shown, the coal mine remote automatic sealing system of the present invention includes automatic sealing devices 3 respectively installed in the air inlet tunnel 1 and the air return tunnel 2 of the mine, and a pneumatic switch 5 arranged in the air inlet tunnel 4 .

[0016] Such as image 3 As shown, the automatic sealing device 3 includes two pneumatic mechanisms 31 arranged at symmetrical intervals and a folding airtight door mechanism 32 arranged between the two pneumatic mechanisms 31 . Each pneumatic mechanism 31 all comprises a top and a bottom end closed hollow fixed rod 311, and on the top of the fixed rod 311 or on the side wall near the top, offer an upper inflation port 312, at the bottom of the fixed rod 311 or near the bottom On the side wall of the end, the gas charging port 313 is opened, and t...

Abstract

The invention relates to remote automatic sealing system and method for a coal mine. The system is characterized by comprising automatic sealing devices which are respectively installed in an air inlet roadway and an air return roadway of a coal mine, as well as a pneumatic switch which is arranged in the air inlet roadway and corresponds to the automatic sealing device. According to each automatic sealing device provided by the invention, a piston arranged in a pneumatic mechanism is pushed under high-pressure gas to move in a fixed rod. As the piston is connected with a movable rod which is provided with an explosion-proof material plate, the explosion-proof material plate arranged at the bottom end of the movable rod drives other explosion-proof material plates to slide down under the action of gravity to form sealed obstruction to prevent the entry of air and reach the purpose of isolating oxygen. When the automatic sealing devices are not needed, the explosion-proof material plates are folded up, so that the system occupies a small space and is convenient to use, and does not affect normal production. The system and method provided by the invention can be widely applied to the field of temporarily and permanently sealing underground worked out sections of mines and the like.

Description

technical field [0001] The invention relates to a closed system and method, in particular to a remote automatic closed system and method for coal mines. Background technique [0002] When a fire breaks out in the mine or the fire cannot be controlled, the measure to be taken is to build an airtight wall, and this measure has various shortcomings and drawbacks, the biggest of which is that during the construction process of the airtight personnel site, high gas, coal dust, etc. Risk factors are always threatening the lives of construction workers in closed fire areas. In recent years, there have been many explosion accidents in the process of airtight construction across the country, causing heavy casualties. Therefore, when a fire breaks out underground or the fire situation cannot be controlled, it is necessary to design a device for quickly sealing the fire area. Contents of the invention [0003] In view of the above problems, the object of the present invention is to...
