Background technology
At present, existing coal mining is mostly underground mining, by old empty water and Cambrian system ash during underground mining
The threat of rock artesian water, drenches (gushing) water spot more, is affected by hydrops bigger in tunneling process in tunnel.Coal mine down-hole tunnel top board
If trickle not only can deteriorate underground work environment, and long-term trickle understands etching apparatus, and roadway floor generation trickle can cause the end
Plate long period of soaking, particularly some soft rock mines can cause roadway floor argillization, the scenes such as pucking occur, and harm mine safety is raw
Produce.Especially go down the hill driving during, meet the palm hydrops poor from row's ability, can stockpile at the production face in tunnel substantial amounts of
Hydrops, and together with pouring (gushing) water is referred and synthesized with coal (rock) powder (granule) in a large number, cause water coal or coal slime, if hydrops can not be timely
Discharging, development machine can cause development machine walking wheels to skid because bottom surface, tunnel is wet and slippery, and then limits the drivage efficiency of development machine,
Have a strong impact on and normally tunnel and carry out production strictly in line with rules and regulations and requisite quality work；And traditional drainage pattern is to use single-stage pump to add diving
Pump, is interrupted and carries out pumping operation, during drawing water, needs to slow down or stop the work of development machine, the most not only draws water
Efficiency is the lowest, and has had a strong impact on the drivage efficiency of development machine.
Usually said tunnel hydrops refers to that the degree of depth is more than 100mm, the continuous length sewage more than 5 meters.Coal mine at present
Lower tunnel, due to infiltration and other reasons, causes return airway, big lane etc. to there is seeping phenomenon, and subregion hydrops is serious, shadow
Ring pedestrian to pass through normally to work with surrounding devices, and in tunnel, particularly return airway exists explosion hazard gases, there is the biggest peace
Full hidden danger.

Enter in this casing 1, simultaneously by impurities bigger in hydrops outside casing 1, prevent the blocking of large-scale foreign material or destroy just dress
Assembly in putting, casing 1 top is provided with the most corresponding with locking system 10, for indicating the finger of this device working water level
Timberline 4, and, for indicating the instruction switch 7 of this device duty, this indicatrix 4 and the setting of instruction switch 7, can make
Operator see the warning line line in tunnel very easily, the working water bit line of this device, and the real-time work of this device
Making state, air inlet 2 is connected on external compression air by pipeline, provides compressed-air power, air outlet 3 to lead to for this device
Piping is connected at membrane pump, thus provides compressed-air power for membrane pump, and the water sucking mouth of membrane pump is placed in collecting-tank 6
In, in the case of casing 1 provides compressed-air power, the hydrops in collecting-tank 6 is extracted out by membrane pump, discharges, permissible from Fig. 1
It is evident that be provided with pneumatic control valve 9 in casing 1, control the pneumatic valve controller that this pneumatic control valve 9 is turned on and off
13, pressure-stabilization filter 5, the compressed air entered through air inlet 2 enters pressure-stabilization filter 5, through voltage stabilizing by pneumatic control valve 9
Compressed air after filter 5 voltage stabilizing processes enters in membrane pump through air outlet 3, it is achieved provide power resources for membrane pump, pneumatic
Connecting on valve control 13 and have the locking system 10 starting or closing this pneumatic valve controller 13, the height of locking system 10 is permissible
Require to arrange according to operating mode warning line, such as, warning line is set and requires to be 300mm, locking system 10 is set accordingly
It is set to bottom casing 1 away from the height of 300mm, it is also possible to warning line is set to other working condition requirements, such as 200mm,
100mm etc., as long as ensureing that the altitude measurement of locking system 10 and working condition requirement are highly consistent, and, this locking system 10
Upper connection has the guide rail 11 extended to bottom casing 1, guide rail 11 is provided with can opposite rail 11 slidably, lock can be touched
The float 12 of locking apparatus 10, float 12 swims in hydrops, consistent with hydrops water surface elevation, when float 12 is along with on hydrops height
When rising and rise to the height of locking system 10, float 12 touches locking system 10, and then promotes locking system 10 action, starts
Pneumatic valve controller 13 action, thus promote pneumatic valve controller 13 to open pneumatic control valve 9, external compression air enters this dress
Put, and start membrane pump work by this device, start to take out the hydrops in collecting-tank 6 outward, can arrange on casing 1 sidewall
Level sensor, and level sensor is arranged at the minimum discharge level of working condition requirement, when hydrops is preferably minimized waterline
After, signal is passed to locking system 10 and touches pneumatic valve controller 13 by this locking system 10 and close by this level sensor
Pneumatic control valve 9, thus close this device, stop pumping, after the water level in collecting-tank 6 arrives warning line, be again started up
This device, starts to draw water, so circulates, it is achieved automatically monitor the water level of collecting-tank 6, and automatically toward extracardiac pumping.
Time specifically used, air inlet 2 is connected on blowing plant, air outlet is connected on membrane pump, then
This device is placed in the hydrops of collecting-tank 6, preferably hydrops bosom, it is also possible to be the low-lying place of hydrops, by the suction of membrane pump
The mouth of a river is placed in hydrops, and when water level arrives the highest warning line, the float 12 risen along with water level touches locking system 10,
Locking system 10 starts pneumatic valve controller 13 and works, and pneumatic valve controller 13 opens pneumatic control valve 9, external compression air from
It is internal that air inlet 2 enters casing 1, and be transported to the air intake of membrane pump after pressure-stabilization filter 5 voltage stabilizing, filtration through air outlet 3
At Kou, starting membrane pump work, carry out draining, after hydrops is reduced to lowest water level line, water level signal is passed by level sensor
Passing locking system 10, locking system 10 starts pneumatic valve controller 13 and works, and pneumatic valve controller closes pneumatic control valve 9,
External compression air is disconnected, and membrane pump quits work, and stops pumping, and when along with the accumulation of hydrops, and reaches maximum water level
After, locking system 10 set out again by float 12, and locking system 10 starts pneumatic valve controller 13 and works, pneumatic valve controller 13 dozens
Drive pneumatic control valve 9, be again started up membrane pump work, draw water, so circulate.
Herein, as in figure 2 it is shown, when instruction switch 7 is in time longitudinal, represent that this device is in running order, when instruction switch 7
In time horizontal, represent that this device is in off working state, it is also possible to be: when instruction switch 7 is in time longitudinal, represent that this device is in
Off working state, when instruction switch 7 is in time horizontal, represents that this device is in running order.Membrane pump in above-described embodiment is also
Can be other Pneumatic water pumps, as long as being capable of pumping for water pump function.
It is understood that above with respect to specific descriptions of the present utility model, be merely to illustrate this utility model and not
It is limited to the technical scheme described by this utility model embodiment, it will be understood by those within the art that, the most permissible
This utility model is modified or equivalent, to reach identical technique effect；Needs are used, all in this reality as long as meeting
Within novel protection domain.
