Description

Technical Field

[0001] The utility model relates to the field of gas collection equipment, in particular to a gas collection pipe for high-gas areas in underground coal mines. Background Art

[0002] Coal mine production is an underground operation. When the tunnel is under pressure, it is easy to form a high-gas area. Since the molecular mass of toxic and harmful gases such as methane and carbon monoxide is smaller than that of air, they are easy to accumulate in the high-gas area. When they accumulate to a certain extent, accidents that endanger production safety are likely to occur. Therefore, it is necessary to regularly detect toxic and harmful gases in the underground high-gas area. The detection method in the prior art is usually to arrange a collection pipe in the high-hat area, but due to falling rocks and liquefied water accumulation on the roof, the pipeline is often blocked, and the pipeline is easily deformed by falling rocks, causing the detection tube to be unable to be used normally. In response to the above problems, there is currently a lack of corresponding solutions. Utility Model Content

[0003] The purpose of the utility model is to overcome the shortcomings of the prior art and provide a gas collection pipe for high-risk areas in underground coal mines which has a simple structure, flexible assembly and arrangement, can realize reciprocating inspection of the detector, and is easy to use.

[0004] The equipment comprises a gas collection pipe, and the gas collection pipe is covered with an anti-smashing shell;

[0005] The anti-smashing housing is in the form of a metal pipe, and an anti-drop cap is arranged on the upper part of the anti-smashing housing through a connecting rod;

[0006] A gas valve is provided at the tail end of the gas collection pipe, and the gas valve is connected to the second collection pipe.

[0007] The effect achieved in this way is that the anti-smash shell and anti-drop cap set on the outside of the collection tube can effectively prevent accumulated water and gravel from falling into the gas collection tube, ensuring the safe and stable operation of the gas collection tube and accurate collection values.

[0008] The beneficial effects of the utility model are as follows: the utility model solves the problems in the prior art that the high-cap area gas extraction equipment is easily blocked, and is deformed and broken by falling gravel. Through a simple structure, gas blockage, deformation or breakage is prevented from occurring. The equipment has a simple structure and is easy to arrange, making it more valuable for promotion.

[0014] Reference Figure 1 The utility model discloses a gas collection pipe for high-risk areas in underground coal mines, comprising a gas collection pipe 2, wherein the gas collection pipe 2 is sheathed with an anti-smashing shell 3;

[0015] The anti-smashing housing 3 is in the form of a metal pipe, and an anti-drop cap 1 is arranged on the upper part of the anti-smashing housing 3 through a connecting rod;

[0016] A gas valve 4 is provided at the tail end of the gas collection pipe 2 , and the gas valve 4 is connected to a second collection pipe 5 .

[0017] Preferably, the second collection pipe 5 is connected to a negative pressure device, and the gas at the top plate position is collected by negative pressure suction for detection.

[0018] The effect achieved in this way is that the anti-smash shell 3 and the anti-drop cap 1 arranged outside the collection tube can effectively prevent accumulated water and gravel from falling into the gas collection tube 2, ensuring that the gas collection tube 2 runs safely and stably and the collected values ​​are accurate.

[0019] Furthermore, the gas collection tube 2 is a flame retardant resin tube, and the second gas collection tube 5 is a rubber tube.

[0020] Furthermore, the upper end of the gas collection pipe 2 is connected to the gas collection shield 6, which is in the form of a metal grid, and is fixedly connected to the anti-smashing housing 3 through a connecting rod. The effect achieved by this is to ensure that the connection between the gas collection pipe 2 and the anti-smashing housing 3 is stable.
