Abstract
The utility model provides a water discharging device for coal mine thousand-meter drilling. The water discharging device comprises a gas pipe and a first switch valve, wherein two ends of the gas pipe are sealed, the first switch valve is arranged on the gas pipe and used for being connected with a drilling pipeline. A wired hose is arranged on the gas pipe and used for being connected with a pumping and discharging main pipeline, a water discharging device negative pressure valve is arranged on the wired hose, a water guiding pipe is arranged at the lower end of the gas pipe, a water discharging valve and a sub pumping and discharging pipeline used for being connected with the main pumping and discharging pipeline are arranged on the water guiding pipe, and a second switch valve is arranged on the sub pumping and discharging pipeline. Compared with a traditional water discharging device, the water discharging device for the coal mine thousand-meter drilling has the advantages that operation is simple, and gas can not dissipate into a drilling field when water is discharged and the like. Meanwhile, a gas pumping and discharging pump on the pumping and discharging main pipeline can continue extracting gas in the water discharging device when water is discharged, and in the water discharging operation, gas in the water discharging device can not be influenced by differential pressure in a drilled hole, gas can not dissipate into the drilling field through a water outlet in the water discharging process, and under the premise that safety is guaranteed, extracting efficiency is improved.
Description
Technical field
The utility model relates to colliery km boring jettison gear special equipment, is specifically related to a kind of colliery km boring tailrace.
Background technology
At present, the down-hole uses traditional tailrace that gas drilling is discharged water always, the tradition tailrace comprises the gas pipe that links to each other with boring pipeline and extraction main line, water, gas that the boring pipeline is discharged in being used for holing are introduced gas pipe, the extraction main line is used for the gas in the gas pipe is carried out extraction, is provided with on the gas pipe be used to the aqueduct that discharges water, after gas pipe is full of, close boring pipeline and extraction main line, discharge water.
Boring with respect to ZDY1900s type rig, 4000L type drilling machine construction, the tradition tailrace can meet the demands, but for ZDY6000LD type rig (km rig), with the boring of this drilling machine construction because too dark (the longest more than 800 meters), gas emission, water yield are all larger in the boring, when boring discharges water to km with traditional tailrace, owing to can't the gas in the aqueduct be carried out extraction, gas can be emitted in the drill site by the dewatering outlet, cause drill site gas to be easy to transfinite, brought very large hidden danger for the safety in production of mine.
Summary of the invention
The purpose of this utility model is to provide a kind of colliery km boring tailrace.
For achieving the above object, the utility model has adopted following technical scheme:
Comprise the gas pipe of closed at both ends and be arranged at the first controlled valve that being used on the gas pipe connects the pipeline of holing, be provided with on the described gas pipe for the wired hose that connects the extraction main line, be provided with the tailrace negative pressure valve on the wired hose, the lower end of gas pipe is provided with aqueduct, the secondary extraction pipeline that is provided with Draw off valve on the aqueduct and is used for connecting the extraction main line is provided with the second switch valve on the secondary extraction pipeline.
The upper end of described gas pipe is provided with the gas-distribution pipe that communicates with outside atmosphere, is provided with gas distribution valve on the gas-distribution pipe.
The relatively traditional tailrace of colliery described in the utility model km boring tailrace, have easy and simple to handle, do not have the advantages such as gas is emitted in the drill site when discharging water.Simultaneously, gas suction pump when discharging water on the extraction main line can continue to extract the gas in the tailrace, and when discharging water operation, gas in the tailrace interior pressure reduction of not holed affects, gas can not be emitted in the drill site by the dewatering outlet in the process that discharges water, guaranteeing to have strengthened extraction efficient under the safe prerequisite.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Among the figure: gas pipe 1, Draw off valve 2, aqueduct 3, second switch valve 4, secondary extraction pipeline 5, extraction main line 6, tailrace negative pressure valve 7, the first controlled valves 8, gas distribution valve 9, gas-distribution pipe 10.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Referring to Fig. 1, the utility model comprises the gas pipe 1 of closed at both ends and is arranged at the first controlled valve 8 that being used on the gas pipe 1 connects the pipeline of holing, be provided with on the described gas pipe 1 for the wired hose that connects extraction main line 6, be provided with tailrace negative pressure valve 7 on the wired hose, the lower end of gas pipe 1 is provided with aqueduct 3, the secondary extraction pipeline 5 that is provided with Draw off valve 2 on the aqueduct 3 and is used for connecting extraction main line 6, be provided with second switch valve 4 on the secondary extraction pipeline 5, the upper end of described gas pipe 1 is provided with the gas-distribution pipe 10 that communicates with outside atmosphere, is provided with gas distribution valve 9 on the gas-distribution pipe 10.
When km boring tailrace need to discharge water, close tailrace negative pressure valve 7, the first controlled valve 8, open simultaneously Draw off valve 2, second switch valve 4, gas distribution valve 9, extraction this moment main line 6 suction functions are on aqueduct 3, water under suction function in the gas pipe 1 and gas begin to outbound flow from aqueduct 3, because gas density ratio water is little, so gas can be on the top of water when flowing out aqueduct 3, most of gas can be drawn into the extraction main line again by secondary extraction pipeline 5 under suction function, when secondary extraction pipeline 5 is extracted the water in the gas pipe and gas out, gas pipe pressure diminish (less than external pressure), this moment, air will constantly enter in the gas pipe through gas-distribution pipe 10 beginnings, be conducive to accelerate the speed that discharges water, prevented effectively that also gas from flowing to drill site through gas-distribution pipe 10.Gas suction pump just can continue to extract the gas in the tailrace when discharging water, and gas can not be emitted in the drill site by the dewatering outlet in the process that discharges water, and has strengthened extraction efficient.
Embodiment
Km boring tailrace mainly is comprised of controlled valve, gas distribution valve, 1 cun major part such as gas-distribution pipe of the wired hose of: 6 meters φ 355 gas pipes, Draw off valve, 2 cun aqueducts, secondary extraction pipeline controlled valve, 1 cun secondary extraction pipeline, connection extraction main line, tailrace negative pressure valve, km boring pipeline.
6 meters φ, 355 gas pipe two ends are shut with closure plate, 1 cun gas-distribution pipe of top welding of on the left side closure plate, 2 cun aqueducts are welded in the closure plate bottom on the right, at 1 cun gas-distribution pipe, on 2 cun aqueducts gas distribution valve is installed respectively, Draw off valve, the wired hose that connects the extraction main line and the wired hose that is connected km boring pipeline are installed respectively on the top of 6 meters φ 355 gas pipes, and connecting the wired hose installation tailrace negative pressure valve of extraction main line, the controlled valve of km boring pipeline is installed at the wired hose that connects km boring pipeline, be connected 2 cun aqueducts 1 cun secondary extraction pipeline to connect with the extraction main line, and at 1 cun secondary extraction pipeline secondary extraction pipeline controlled valve be installed.
