Abstract
The invention relates to a quick drainage and hole sealing gas parameter testing system, which can effectively solve the problem that coal seam gas parameters cannot be tested because a test chamber has water when the water-contained-coal-seam gas parameters in coal seam roof rocks containing water are tested, solve the problem that the water leaks into the test chamber from the wall rocks, solve the problems of long hole-sealed time and recycling failure and save a great amount of raw materials. In order to solve the technical problem, the invention adopts a technical scheme that: a round sheet steel with an eyelet is arranged at a joint of a testing pipe and the test chamber; a round film is tightly attached to the round sheet steel; the round film and the round steel with the eyelet are concentrically fastened on the testing pipe; the round film conducts the functions of introducing wind from the testing pipe to blow off the water in the test chamber and preventing the water from returning to the test chamber; a high-pressure gas is charged into a hole packer to heave the cylindrical film to seal a water-contained layer and prevent water from leaking into the test chamber; and the water in the testing chamber is drained from a drain pipe after the hole is sealed by the hole packer and an instrument can be arranged to test the parameters after the water is completely drained. The testing system is simple, novel and unique in structure, convenient to install and use, good in hole-sealed effect and small in labor intensity and can be reused for a plurality of times to save a great mount of raw materials. The testing system represents a great innovative product with obvious commercial, social environmentally-friendly efficiencies in the coal mine industry.
Description
One, technical field
The present invention relates to the colliery industry, particularly a kind of quick drainage and hole sealing gas parameter testing system
Two, background technology
During existing coal-bed gas parameter testing sealing of hole, with polyamine fat or cement mortar sealing of hole, and polyamine fat and cement mortar all can not be reused, besides with polyamine fat and cement mortar sealing of hole once when running into the roof aquifer behind the sealing of hole, the water of parameter testing chamber is arranged again and be can't get out, cause parameter not surveyed, the hole game of shuttlecocks.Waste great amount of manpower and material resources, financial resources and the time.So it is imperative that it innovates a kind of novel quick drainage and hole sealing gas parameter testing system.
Three, summary of the invention
Purpose of the present invention is exactly to be to provide a kind of water with coal-bed gas parameter testing chamber to discharge not only to cut off the aquifer to parameter testing chamber trickle but also reusable quick drainage and hole sealing gas parameter testing system.
Technical scheme of the present invention is to beat gases at high pressure by feed tube cylindrical rubber is heaved the effect of aquifer to the test cabinet trickle of sealing, the fluid column hole packer is sealed the water of back test cabinet and is discharged with effect between gutter and the testing tube, instrument can be installed behind the emptying water carry out parameter testing.
Four, description of drawings
Side of the present invention mentioned above and and other features will be described in conjunction with relevant drawings hereinafter, wherein:
Fig. 1 is a structured testing end elevation view of the present invention
Fig. 2 is that end of the present invention and circular film are installed front view
Fig. 3 is each section front view of sealing of hole post
Fig. 4 has been the circular film structure figure of against current valve effect
Fig. 5 is a nut of having fixed the circular film of against current valve effect
Five, the specific embodiment
Below in conjunction with accompanying drawing concrete enforcement of the present invention is elaborated
Provide by Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5.
Quick drainage and hole sealing gas parameter testing system mainly is made up of rubber hole sealing glue post (8), connection screwed pipe (11), gutter (6), the air supply pipe (9) of parameter testing pipe (5), cylindrical shape; Hole packer is made up of rubber hole sealing glue post (8), connection screwed pipe (11), gutter (6), the air supply pipe (9) of parameter testing pipe (5), cylindrical shape; Be connected with the round steel sheet that has eyelet, the circular film that plays the against current valve effect between hole packer and the parameter testing end.Between the hole packer series connection be air supply pipe (9) with air supply pipe (9), gutter and gutter with high pressure resistant flexible pipe be connected, the parameter testing pipe is connected with the parameter testing pipe.
Implementing measure of the present invention is:
1: the diameter of boring and the diameter of hole packer are complementary, otherwise can be along bad hole packer;
2: just seen the hole depth of coal when remembeing to hole, so that determine to place the degree of depth of hole packer;
3: just during sealing of hole with first hole packer and circular film concentric this group equipment that is tightly fixed on the test cabinet of circular steel disc with holes, one in the same way under the eyelet, gutter in the hole packer is connected with high pressure resistant flexible pipe, air supply pipe is connected with high pressure resistant flexible pipe, these high-pressure hoses are received outside the hole always, this group equipment is delivered to testing tube not till the flowing water, illustrate that this group do not cross the aquifer fully, remember this segment distance, illustrate that the end, aquifer is exactly this segment distance far from the aperture, just be to seal aquifer and coal seam this segment distance of this section interaction during sealing of hole, after this group equipment pulled out, redefine sealing of hole distance and sealed borehole length.
Circular steel disc and circular film role are to determine to press wind that the water of test cabinet is blown off and the effect of not flowing back to test cabinet from testing tube, moreover the distance of definite non-aquifer and eyelet, and it can also determine that water is the roof water or the base plate water of coal;
4: after determining sealing of hole distance and sealed borehole length, determine series connection hole packer number, must note this moment connecting between the fluid column hole packer be air supply pipe with air supply pipe with high pressure resistant flexible pipe be connected, gutter and gutter with high pressure resistant flexible pipe be connected, the parameter testing pipe is connected with the parameter testing pipe;
5: after the fluid column hole packer number of will determining to connect is delivered to the sealing of hole position, send into gases at high pressure, hole packer is heaved and sealed orifice to hole packer;
6: with interacting between gutter and the testing tube, get final product the installation testing instrument behind the envelope orifice, carry out parameter testing with the water emptying of test cabinet.
The parameter of measuring so accurately, reliable, after parameter testing finishes, this complete equipment can be withdrawn after emulsion unloaded, reuse.Patent structure of the present invention is simple, novel, unique, easy to install.Sealing of hole is effective, and labour intensity is little, can also be repeatedly used the saving great deal of raw materials.Be an innovation greatly of colliery industry, business efficiency, social efficiency, environmental protection efficient highly significant.
