Description
Technical field
The utility model belongs to mine gas prevention and control field, is specifically related to a kind of rapid hole packer for gas testing bore holes and interim extraction borehole.
Background technology
Coal and Gas Outburst are one of natural calamities the most serious under coal mine, and Accurate Prediction coal and Gas Outburst have important function to control coal and Gas Outburst.Drilling gas is gushed out initial velocity as one of important indicator of forecasting coal and Gas Outburst, and the agility of the rapid hole packer operation that it adopts, the quality of sealing of hole effect directly affect measurement result.
In addition, when the interim extraction of coal-bed gas, the quality of the agility of rapid hole packer and sealing of hole effect also affects extracting result.Therefore, a kind of novel rapid hole packer for gas testing bore holes and interim extraction borehole swift to operate, that sealing of hole is effective of design invention is significant.
Utility model content
The purpose of this utility model is to provide the rapid hole packer that a kind of result is simple, swift to operate, sealing of hole is effective.
For achieving the above object, the utility model adopts following technical scheme: rapid hole packer, the measurement chamber pipe, capsule hole sealing tube and the wireway that comprise docking successively, pipe outer ring around capsule hole sealing tube is wound with expanded capsule, the two-port of expanded capsule is sealingly fastened in respectively the both sides of capsule hole sealing tube, and expanded capsule is connected with gas tube.
Described gas tube is provided with pressure meter, and the end of gas tube connects source of the gas.
Described source of the gas is inflator.
Described source of the gas is down-hole air line.
The shutoff of measurement chamber pipe one end, the other end connect described capsule hole sealing tube, and the pipe shaft of measurement chamber pipe is provided with several air vents.
Described wireway arranges several, and several wireways are for docking by snap joint between docking and adjacent two wireways successively.
Rapid hole packer described in the utility model, rapid hole sealing that can be to gas testing bore holes and interim extraction borehole, the utility model is simple in structure, simple and quick, sealing of hole good sealing effect, can derive fast gas in coal seam.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Rapid hole packer as shown in Figure 1, comprise the measurement chamber pipe 10, capsule hole sealing tube 9 and the wireway 6 that dock successively from front to back, wireway 6 arranges several, several wireways 6 dock successively for front and back, and by snap joint 7, dock (snap joint 7 is prior art, therefore do not describe in detail) between adjacent two wireways 6.Measurement chamber pipe 10 front end sealings, rear end connect described capsule hole sealing tube 9, the pipe shaft of measurement chamber pipe 10 is provided with several air vents 1, the rear port of measurement chamber pipe 10 docks with the front port of capsule hole sealing tube 9, the rear port of capsule hole sealing tube 9 docks with the front port of first wireway 6, and the rear port of last wireway 6 is by joint 8 connecting test sebific duct or drainage tubes.Gas can enter by air vent 1 capsule hole sealing tube 9 and each wireway 6 of hole packer, finally enter test sebific duct or drainage tube, wherein wireway 6 quantity are determined according to hole depth, can constantly increase wireway 6 by connecting snap joint 7, to increase the overall length of wireway 6.
Pipe outer ring around capsule hole sealing tube 9 is wound with expanded capsule 2, and expanded capsule 2 has the features such as antistatic, fire-retardant, durable.The forward and backward two-port of expanded capsule 2 is sealingly fastened in respectively the both sides, front and back of capsule hole sealing tube 9, the front port of expanded capsule 2 and rear port can be fixed on respectively the both sides of capsule hole sealing tube 9 by two clip sealings, expanded capsule 2 is connected with gas tube 3, described gas tube 3 is provided with pressure meter 4, one end of gas tube 3 connects expanded capsule 2, the other end connects source of the gas, and source of the gas is inflator 5.Expanded capsule 2 is harmomegathus structure, because expanded capsule 2 two-port are closed in the both sides of capsule hole sealing tube 9, between expanded capsule 2 and capsule hole sealing tube 9, form airtight inflatable chamber, when source of the gas is filled with gas between expanded capsule 2 and capsule hole sealing tube 9, expanded capsule 2 bulges and blocks up real boring, and pressure meter 4 can show the pressure value in gas tube 3 and capsule.
Certainly, the utility model is not limited to above-mentioned form, and described source of the gas also can be down-hole air line.
Rapid hole packer described in the utility model, utilizes expanded capsule 2 to expand and blocks up real boring, and the principle that in coal seam, gas is discharged by the air guide channel in pipeline is carried out rapid hole sealing.
The using method of rapid hole packer described in the utility model is:
1. prepare the wireway 6 of each parts of hole packer and enough joint numbers, check in fast joint, whether O type circle has breakage, as found disappearance or can not normally using, should change in time;
2. after drilling construction completes, connect successively measurement chamber pipe 10, capsule hole sealing tube 9, gas tube 3, and by fast joint, connect the wireway 6 of enough joint numbers;
3. use inflator 5 or other compressed air source unit to the interior inflation of expanded capsule 2 on capsule hole sealing tube 9, until pressure meter 4 shows that numerical value are to precalculated position (assurance can not outwards be stirred with hand);
4. by snap joint 7 by the rear port connecting test device of tail end wireway 6 or extraction pipeline, test or extraction;
5. after measuring, pull out connecting line in snap joint 7, discharge the gas in expanded capsule 2 simultaneously, hole packer is extracted, coal dust installing in order to using next time on cleaning hole packer.
