Description
Technical field
The present invention relates to mining equipment more particularly to a kind of longhole infusion hole packers.
Background technique
The accidents such as China's gas ejection, coal and gas prominent, gas explosion happen occasionally.Coal-bed flooding, standing, coal
The technologies such as layer hydraulic fracturing are to prevent and treat the effective means of Gas Disaster.Effective sealing of hole is to realize efficient water injection, safe standing
With the most important condition of high-efficiency hydraulic pressure break.Conventional drilling and sealing method, can also other than using the sealing of holes such as cement mortar, yellow mud
To use sebific duct hole packer sealing of hole.Conventional coal-bed flooding sebific duct hole packer is divided into two kinds: one is have in sebific duct installed inside
Pressure-bearing check valve realizes coal-bed flooding, this is limited by coal-bed flooding pressure, the pressure inside sebific duct is not generally high, furthermore
Pressure-bearing check valve precision is undesirable, and it is undesirable that this results in sealing of hole effect.Sebific duct especially is used to block the process of blast hole
In, if sebific duct internal pressure is inadequate, it is easy to sebific duct be caused to be spilled over blowing out moment.Another kind is pacified in one end of sebific duct
Equipped with sealing chute, cause Length Contraction after dilation by water injection to adapt to sebific duct, avoids sebific duct bad by internal pipeline support.Due to
The sealing effect of sealing chute is undesirable, leak is easy when high pressure, and be easily damaged;Additionally due to the pipeline one inside sebific duct
As be hard pipeline, shrinkage is poor, when sealing chute damage after, it is easy to cause sebific duct to damage in the injecting process.
Summary of the invention
The purpose of the present invention is to provide a kind of fixed telescopic longhole infusion hole sealing devices in middle part in both ends.
To realize the above goal of the invention, technical scheme is as follows:
A kind of longhole infusion hole packer, including outer sebific duct, pouring water into borehole pipe and capsule water injection pipe, the both ends of outer sebific duct are fixed
On capsule plug, the capsule plug at outer sebific duct and both ends constitutes closed cavity, and the both ends of pouring water into borehole pipe are each passed through two
Capsule plug is simultaneously separately fixed on two capsule plugs, and pouring water into borehole pipe, which is located at the intracorporal part of closing chamber, has a Duan Weike to stretch
The draw, pouring water into borehole pipe both ends are stereoplasm tube close to the part of two capsule plugs, and capsule water injection pipe is located in one of capsule
On plug, one end of capsule water injection pipe is protruded into closed cavity.
Technical solution as a further improvement of that present invention, the stereoplasm tube are welded on the capsule plug.
Technical solution as a further improvement of that present invention, the stereoplasm tube and the capsule plug are metal.
Technical solution as a further improvement of that present invention, the metal are iron, stainless steel or aluminium alloy.
Technical solution as a further improvement of that present invention, the stereoplasm tube and the capsule plug are rigid plastics.
Technical solution as a further improvement of that present invention, the telescopic tube are hose.
Compared with prior art, beneficial effects of the present invention:
1. a kind of longhole infusion hole packer of the invention, pouring water into borehole pipe are divided into three sections in hole packer, middle section is hose,
It is suitable for sebific duct contraction distortion, compared to existing metal tube, weight is lighter, bending deformation is also easier to, so that entire envelope
Hole device, which can be bent, is suitable for drilling of various shapes;
2. a kind of longhole infusion hole packer of the invention, in assembly, pouring water into borehole pipe is straight close to the part of sebific duct plug
It connects and welds together with sebific duct plug, reduce leakage point, ensured the leakproofness in high pressure water injection, and eliminate traditional
Sealing chute overcomes slideway defect easy to damage, and performance is more stable, is more suitable for the sealing of hole of blasting boreholes and water injecting drilling
Operation;
3. a kind of longhole infusion hole packer of the invention, hole packer inside is hose, weight is significantly reduced, is greatly reduced
The weight of hole packer, and reduce sealing of hole component, it is easy to process.

Embodiment
As depicted in figs. 1 and 2, a kind of longhole infusion hole packer, including outer sebific duct 1, pouring water into borehole pipe 4 and capsule water injection pipe
10.Outer sebific duct 1 can be expanded in internal pressure-bearing, and the both ends of outer sebific duct 1 are separately fixed on capsule plug (2,3), outer sebific duct 1
Closed cavity is constituted with the capsule plug (2,3) at both ends.The both ends of pouring water into borehole pipe 4 are each passed through two capsule plugs (2,3)
And it is separately fixed on two capsule plugs (2,3).It is scalable that pouring water into borehole pipe 1, which is located at the intracorporal part of closing chamber to have one section,
Hose 5,4 both ends of pouring water into borehole pipe close to the part of two capsule plugs (2,3) be stereoplasm tube (6,7), capsule water injection pipe 10
It is located in one of on capsule plug, one end of capsule water injection pipe 10 is protruded into closed cavity.Sebific duct plug (2,3) and stereoplasm tube
(6,7) can may be rigid plastics for metal materials such as steel, stainless steel, aluminium alloys.
When assembly, pouring water into borehole pipe 4 is passed through from the inside of outer sebific duct 1, the stereoplasm tube (6,7) at 4 both ends of pouring water into borehole pipe
It is each passed through sebific duct plug (2,3), hose 5 is located at the inside of outer sebific duct 1, then stereoplasm tube (6,7) and sebific duct plug (2,3) are divided
It does not weld, weld 8 and weld 9 can make entire hole packer have extraordinary leakproofness in the case where ensureing sealing effect
Energy.In conventional similar hole packer design process, inside be generally used the metal tubes of hard, due to note inside hole packer
When water expands, length can be shunk, therefore internal metal tube can must also be shunk, this is generally by one telescopic chute of series connection
It realizes, and telescopic chute is generally located at sebific duct plug position, only one end is to be welded on one with sebific duct plug to inner tube
It rises, the other end is sealing sliding.It needs to be tightly connected at slideway, leak will not occur when high pressure water injection for guarantee, long
Time using when slideway be easy to damage, so as to cause entire hole packer damage.A kind of longhole infusion hole packer of the invention its
Inside is hose 5, can be deformed with the flexible of hole packer, therefore installation slideway is not needed inside it, the two of pouring water into borehole pipe 4
End and the sebific duct plug (2,3) at outer 1 both ends of sebific duct directly weld, easy to process and reduce leakage point, substantially increase sealing
Effect is highly suitable for the sealing of hole operation of blasting boreholes and water injecting drilling.In addition, 5 lighter in weight of hose, is greatly reduced sealing of hole
The overall weight of device.
