Abstract
The invention relates to a gas leakage detection apparatus of a coal mine gas drainage pipeline. The apparatus can effectively detect whether there is a leakage problem at a joint. A technical scheme of the invention is characterized in that the apparatus comprises a fixed plate, a U-shaped pipe and a drainage pipeline; the U-shaped pipe is upwardly and vertically arranged on the fixed plate; two end surfaces of the U-shaped pipe are in a same horizontal plane; the U-shaped pipe is filled with water; the joint of the drainage pipeline is surrounded by a high elastic rubber so as to form a sealing space; an extended conduit is arranged in the sealing space; the conduit is connected with the U-shaped pipe through a connection hose. The structure of the invention is simple, practical and high-efficient. A usage effect is good. The apparatus is an innovation of the gas leakage detection apparatus of the gas drainage pipeline.
Description
Technical field
The present invention relates to the colliery device, particularly a kind of coal mine gas drainage pipe road gas leak detection device.
Background technology
According to " control coal and Gas Outburst regulation ", " coal mine gas drainage basic index " (AQ1026-2006) requirement, coal and gas outburst mine must be set up gas drainage system, and negative pressure extraction (negative pressure of extraction drill hole is greater than 13KPa) is adopted in the gas drainage under the present coal mine, in extraction pipeline, arm particularly, mostly adopt the PE pipe as releasing pipe, connect threeway in the releasing pipe, straight-through, elbow is many, whether the gas leakage of junction directly has influence on height and the length in extraction cycle of negative pressure of suction, direct relation has been taken in safety in production and production to mine, does not have at present the device whether the direct-detection junction leaks gas.If can to where leak gas by direct-detection, and disposed, to improving negative pressure of suction very large benefit is arranged, both improved the amount of drawing out methane, also improved the concentration that draws out methane, for the efficient utilization of gas is laid a good foundation.Therefore, the improvement of coal mine gas drainage pipe road gas leak detection device is the problem of needing at present solution badly.
Summary of the invention
For above-mentioned situation, for solving the defective of prior art, the present invention's purpose just provides a kind of coal mine gas drainage pipe road gas leak detection device, can effectively detect the problem whether junction leaks gas.
The technical scheme that the present invention solves is, comprise fixed head, U-shaped pipe and extraction pipeline, the U-shaped mouth of pipe upwards vertically is contained on the fixed head, U-shaped pipe both ends of the surface are on the same level face, in the U-shaped pipe water is housed, the extraction pipeline junction around consisting of seal cavity, has the conduit that stretches out by high elastic rubber in the seal cavity, conduit is connected with U-shaped pipe through connecting hose.
The present invention is simple in structure, practicality and high efficiency, and result of use is good, is the innovation on the gas drainage pipeline gas leak detection device.
Description of drawings
Fig. 1 is structural front view of the present invention.
Embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present invention is described in further detail.
Provided by Fig. 1, the present invention includes fixed head 6, U-shaped pipe 5 and extraction pipeline 3,5 mouthfuls of U-shaped pipes upwards vertically are contained on the fixed head 6, U-shaped pipe 5 both ends of the surface are on the same level face, in the U-shaped pipe 5 water 8 is housed, extraction pipeline 3 junctions around consisting of seal cavity 7, have the conduit 2 that stretches out by high elastic rubber 1 in the seal cavity 7, conduit 2 is connected with U-shaped pipe 5 through connecting hose 4.
In order to guarantee result of use, the liquid level of described water 8 is lower than the position that is communicated with of U-shaped pipe and connecting hose 4.
The circle that described conduit 2 is made for plastics.
The round tube that described connecting hose 4 is made for rubber, its internal diameter is identical with the internal diameter of conduit 2.
Operating position of the present invention is with the junction of high elastic rubber 1 around extraction pipeline, to make the junction form a seal cavity, draw a conduit from seal cavity, conduit is connected on " U " type pipe, in " U " type pipe water is housed, and the liquid level of water is to mouth of pipe 3cm, when " U " type pipe two ends liquid level is equally high, show air tight, if when " U " type pipe two ends liquid level is different, gas leakage is described, the two ends liquid level differs more, illustrates that gas leakage is more serious.
The present invention is simple in structure, practicality and high efficiency, and result of use is good, is the innovation on the gas drainage pipeline gas leak detection device, has good economic and social benefit.
