Description

Coal mine goaf bundle pipe gas collecting and storing device and using method thereof

The technical field is as follows:

the invention belongs to the technical field of goaf bundle pipe monitoring, and particularly relates to a coal mine goaf bundle pipe gas collecting and storing device and a using method thereof.

Background art:

the coal mine goaf has the danger of spontaneous combustion, so the coal mine usually adopts a goaf bundle pipe burying method to monitor gas in the goaf, judges whether the coal left in the goaf is spontaneous combustion or not according to the concentration and the type of various gases in the goaf, and adopts further prevention measures. Therefore, the beam tube monitoring system has important significance for coal mine safety production.

At present, underground workers mainly utilize the rubber ball bladder to collect the beam tube monitoring gas, and then use the clamp to clamp the ball bladder air inlet pipe to carry the gas to the well. The gas collection of the ball bladder is difficult to control the gas collection amount, and the gas collection is excessive, so that the service life of the ball bladder is easily shortened; the air inlet pipe is easily broken due to repeated bending of the air inlet pipe, and the clamp is also easily lost; in addition, when multi-point gas collection is carried out, the movement of underground workers can be seriously influenced by carrying a large number of gas-filled bladders, and certain inconvenience is caused.

Therefore, the rubber ball bladder of the beam tube monitoring gas collection container at present has many defects, so that a beam tube gas collection and storage device in a coal mine goaf is needed to be provided, so that the gas collection efficiency is improved, and the gas collection work of underground workers is facilitated.

The invention content is as follows:

the invention aims to overcome the defects in the prior art and provide a coal mine goaf bundle pipe gas collecting and storing device and a using method thereof, which improve the gas collecting efficiency, reduce the loss of frequent damage of a rubber ball bladder, facilitate the action of underground workers and improve the efficiency of underground bundle pipe gas collecting work.

In order to achieve the purpose, the invention adopts the following technical scheme:

the utility model provides a coal mine goaf beam tube gas collection storage device, includes the casing, be provided with a plurality of rubber gasbag storage check in the casing, rubber gasbag storage check top is equipped with independent lid, independent lid surface is equipped with the air inlet, the air inlet below is connected with the rubber gasbag, the air inlet top is equipped with the valve.

The casing is the plastics material, the casing is square body or cylinder.

The shell is connected with a shell protective cover so as to protect the collected gas.

The lateral part of the shell is provided with a hand strap.

The rubber air bag storage grid is of an independent structure so as to be convenient to put in and take out; the rubber air bag storage grids are adjacently arranged to fill the inside of the shell.

The rubber air bag storage grids are used for respectively collecting the gas to be detected.

The rubber air bags are separated by the restriction clamping plates and are arranged in the plastic shell through the restriction clamping plates arranged in the shell.

The air inlet can be connected with the rubber air bag inside and is fixed on the independent cover body of the plastic shell, so that connection and sealing are guaranteed.

The valve is arranged outside the air inlet, and the air inlet and the air outlet of the rubber air bag can be controlled through the switch.

The use method of the coal mine goaf beam tube gas collecting and storing device comprises the following steps:

(1) evacuating waste gas in each rubber air bag by using an air pump, covering a protective cover to bring the device into the underground;

(2) connecting the beam tube with an air pump and then with an air inlet in the underground;

(3) opening a valve and a power supply of the air pump, and closing the valve and the air pump after the rubber air bag is filled with air;

(4) repeating the steps to finish the gas collection of different measuring points;

(5) and closing the protective cover and bringing the protective cover to the ground for gas detection.

The invention has the beneficial effects that:

(1) unnecessary economic loss caused by frequent damage of the rubber ball bladder is reduced, and the capital investment of the bundle tube monitoring work is saved.

(2) The clamp is prevented from being lost and the work is inconvenient due to the breakage of the rubber bladder air inlet pipe, and the efficiency of the bundle pipe gas monitoring work is improved.

(3) When multi-measuring point gas collection is carried out, inconvenience brought to underground workers by carrying a large number of rubber ball bladders is avoided.
