Abstract
The utility model relates to a gas-column bore sealer which can effectively solve the problems of long bore-sealing time of the coal seam gas drainage bore, poor sealing effect, no repeated use and resource waste in the prior art. The technical proposal is as follows: the exterior of a gas drainage pipe is sleeved with a cylindrical gas column formed by a gas chamber, an inner wall and an outer wall; a gas inlet/outlet port is formed at one end of the gas column and provided with a control valve; and the two ends of the gas column are fixed with the exterior of the gas drainage pipe via connectors. The gas-column bore sealer has the advantages of simple and novel structure, easy operation, good use effect, less labor intensity, repeated use, reduced resource waste, novelty in coal mining industry and good social and economic benefits.
Description
One, technical field
The utility model relates to the colliery industry, particularly a kind of gas column hole packer.
Two, background technology
During existing coal-bed gas extraction, the extraction pipeline need be at seal section place mash gas extraction in coal bed drilling, but coal and gas outburst mine mostly is a low permeability coal seam, the extraction coal-bed gas is difficulty relatively, the sealing of hole mode of carrying out though draw out methane at present has a lot, need the sealing of hole time long first, second operate more complicated, and it is insecure all to exist sealing, can not reuse, waste resource greatly, increase problems such as labour intensity, simultaneously also exist potential safety hazard, so its innovation is imperative.
Three, utility model content
At above-mentioned situation, the purpose of the utility model just provides a kind of gas column hole packer, the sealing of hole time of the coal-bed gas extraction borehole in the time of can effectively solving extraction is long, and seal insecure, can not reuse, the waste problem of resource, the technical scheme of its solution is: gas pumping pipe outer cover is equipped with the gas annular column body that is made of air chamber and inwall, outer wall, gas column body one end has the air intake-exhaust mouth of band control valve, and gas column body two ends are fixed on gas pumping pipe outside by fixed body.The utility model is simple in structure, novel, unique, uses easy to operately, effective, and labour intensity is little, can also reuse, and has reduced the unnecessary wasting of resources, is that one in the industry of colliery innovated obvious social benefit greatly.
Four, description of drawings
Fig. 1 is a structural profile front view of the present utility model.
Fig. 2 is a structure right view of the present utility model.
Five, the specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is elaborated.
Provide by Fig. 1, Fig. 2, the utility model is that gas pumping pipe 1 outer cover is equipped with the gas annular column body that is made of air chamber 2 and inwall 3, outer wall 4, gas column body one end has the air intake-exhaust mouth 6 of band control valve 7, and gas column body two ends are fixed on gas pumping pipe outside by fixed body 5.
In order to guarantee convenient maintenance, the fixed body 5 outer fixed screws 8 that are installed with of an end of said air intake-exhaust mouth 6.
Mode of occupation of the present utility model is the gas pumping pipe to be inserted in the hole of having bored, when carrying out extraction, toward air intake-exhaust mouth inflation pressurization, make the air chamber bulging, match until complete and boring, played the sealing of hole effect, after extraction finishes, the gas in the air chamber has been emitted, can extract the gas column hole packer out, so can use repeatedly, method of operating is simple, has saved great amount of manpower and material resources, result of use is good, as applies good society and economic benefit.
