Technical field
The present invention relates to coal mine gas drainage field, is specially to drilling integrate draining gas pumping integrated apparatus under one kind.
Background technology
Gas pumping is control of coalmine gas and the essential measure and main path that utilize, drilling gas extracting result it is good
Badly except the reasonable Arrangement with drilling, drilling and sealing quality is relevant, additionally depends on guard aperture deslagging, drainage measure in drilling construction
Quality.
Field practice proves, during hole pumping and mining, due to by construction technology, and coal seam hydrogeologic condition and aqueous
The natural causes such as rate influence, while existing sealing of hole and guard aperture measure, and it cannot be guaranteed that coal petrography crevice water seepage flow enters drilling, under
Substantial amounts of water is often accumulated into drilling hole, and it is deeper due to drilling, aperture is small, and hole internal water accumulation is difficult to discharge, and then blocks
The crack passage of Gas Flow in coal seam, while in weak seam, prolonged ponding can cause hole wall to send group to collapse in drilling
Collapse, and then collapse hole occurs, influence gas pumping effect.
Existing drainage equipment such as draining jet pump etc., its conversion time between extraction and draining are grown, and complex operation is same
When be also easy to Gas occur, while need extra power set to exist, it is big to take volume, increases the workload of worker, and
Economized and high efficiency can not be accomplished.
It would therefore be highly desirable to need to be improved prior art, design under one kind to drilling integrate draining gas pumping integration
Device extends the interval of mash gas extraction come the inner product shipwreck discharge that solves to drill in the prior art, reduces operating efficiency, drilling it is close
The problems such as envelope property is difficult to ensure that.
The content of the invention
It is an object of the invention to provide a kind of theme, to solve the drilling inner product of the proposition proposed in above-mentioned background technology
The problems such as shipwreck is discharged, and operating efficiency is low, and the sealing of drilling is difficult to ensure that.
To achieve the above object, the present invention provides following technical scheme：To drilling integrate draining gas pumping integration under one kind
Device, including be responsible for, press wind branch pipe and L-shaped branch drain, it is characterised in that：One end installation supervisor's valve of the supervisor, institute
The side for stating supervisor is provided with circular opening, and one end of the L-shaped branch drain enters main pipe by circular opening and extended
Go out the other end of supervisor, and packing matcrial layer between the space formed between circular opening and the outer wall of branch drain, the L
One end installation branch drain valve of the shape branch drain outside supervisor, the L-shaped branch drain are located at the one of main pipe
One end of spiral connecting pipe hoop is held, and one end of the other end connection rubber tube of pipe collar, the side of the supervisor are welded to connect pressure wind
The bottom of branch pipe, and press wind branch pipe to pass through close to one end of supervisor installation pressure wind branch pipe valve, the other end of the pressure wind branch pipe
Flexible pipe connects pressure ventilation pipe.
Preferably, the supervisor is a diameter of 40mm iron pipe.
Preferably, the pressure wind branch pipe is a diameter of 19mm iron pipe.
Preferably, the L-shaped branch drain is the zinc-plated a diameter of 12.5mm in surface iron pipe.
Preferably, the length that the L-shaped branch drain extends supervisor one end is 20cm.
Preferably, filled using elastic rubber layer in the space formed between the L-shaped branch drain and circular opening outer wall.
Compared with prior art, the beneficial effects of the invention are as follows：To drilling integrate draining gas pumping integrated apparatus under this, lead to
Cross take out, pressure power combine mode, using valve come control supervisor in positive and negative pressure come realize drilling gas extraction and drilling accumulate
The outer row function of water, relative to existing pump drainage water installations, structural volume is small, the pressure wind apparatus of underground is rationally make use of, without carrying
It is that the switching between mash gas extraction and draining can be achieved by Valve controlling for extra power source and affiliated facility, simple to operate,
Convenient, stability is good, strong applicability.
Brief description of the drawings
Fig. 1 is schematic structural view of the invention；
Fig. 2 is the schematic internal view that one end is responsible for when the present invention uses.
In figure：Supervisor 1, supervisor's valve 1-1, pressure wind branch pipe 2, pressure wind branch pipe valve 2-1, L-shaped branch drain 3, draining branch
Tube valve 3-1, pipe collar 4, sebific duct 5 and pressure ventilation pipe 6.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, rather than whole embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other under the premise of creative work is not made
Embodiment, belong to the scope of protection of the invention.
Fig. 1-2 is referred to, the present invention provides a kind of technical scheme：Integrally disguise to drilling integrate draining gas pumping under one kind
Put, including supervisor 1, pressure wind branch pipe 2 and L-shaped branch drain 3, supervisor 1 are a diameter of 40mm iron pipes, are responsible for 1 one end installation
Valve 1-1 is responsible for, the side for being responsible for 1 is provided with circular opening, and L-shaped branch drain 3 is the zinc-plated a diameter of 12.5mm in surface iron
Pipe, one end of L-shaped branch drain 3 enters the inside of supervisor 1 by circular opening and extends the other end 20cm of supervisor 1, and circle
Filled between the space formed between the outer wall of shape hole and branch drain 3 using elastic rubber layer, L-shaped branch drain 3 is positioned at master
One end installation branch drain valve 3-1 outside pipe 1, one end spiral connecting pipe hoop 4 of the L-shaped branch drain 3 inside supervisor 1
One end, and one end of the other end connection rubber tube 5 of pipe collar 4, the side for being responsible for 1 is welded to connect the bottom of pressure wind branch pipe 2, presses wind
Branch pipe 2 is a diameter of 19mm iron pipe, and presses wind branch pipe 2 to press wind branch pipe close to one end of supervisor installation pressure wind branch pipe valve 2-2
2 other end connects pressure ventilation pipe 6 by flexible pipe.
Operation principle：When under using this to drilling integrate draining gas pumping integrated apparatus, supervisor 1 is connected with sebific duct 5
One end is put into gas drilling, the free end of sebific duct 5 is located at the bottom of gas drilling, and connect in supervisor's mouth with drilling gas aperture
Encapsulation process is carried out in tactile region, ensures the overall air-tightness of device.Carry out gas pumping when, close pressure wind branch pipe valve 2-1 and
Branch drain valve 3-1, the supervisor valve 1-1 on supervisor 1 is opened, gas pumping is carried out using the negative pressure in supervisor 1；Work as drilling
When internal water accumulation is more, supervisor valve 1-1 is closed, stops gas pumping, open branch drain valve 3-1 and pressure wind branch pipe valve 2-
1, the gas in pressure ventilation pipe 6 is entered back into drilling, because the air pressure in drilling increases by pressing wind branch pipe 3 to enter in branch pipe 1
Greatly, the water of foot of hole is pressed into sebific duct 5, and the water in sebific duct 5 flows further through L-shaped branch drain 3, from L-shaped branch drain 3
Another port discharge, so as to realize by inside gas drilling ponding discharge.
Although the present invention is described in detail with reference to the foregoing embodiments, for those skilled in the art,
It can still modify to the technical scheme described in foregoing embodiments, or which part technical characteristic is carried out etc.
With replacing, within the spirit and principles of the invention, any modification, equivalent substitution and improvements made etc., this should be included in
Within the protection domain of invention.
