Top is provided with vacuum meter and water injection valve；Water butt is connect by pump water inlet with unit fixed on water pump suction, and pump water inlet is close to storage
One end of bucket is provided with hand door a；Water pump is connect with motor；Connect in exit of pump with drainpipe, on drainpipe according to
It is secondary to be provided with pressure gauge, multi-functional control valve of water pump, hand door b, hand door c and electromagnetic flowmeter；At the top of water butt
Higher than water pump；
Further, one end that suction hose gos deep into absorbing well, absorption well is provided with strainer；
Further, one end that suction hose is connect with water butt is protruded into inside water butt, built-in length 10mm；Water storage
Bucket bottom is provided with pedestal；
Further, multifunctional water pump control valve is set to pump outlet, the work pressure of multifunctional water pump control valve
For power between 1.0-10.0MPa, operating pressure is greater than or equal to 0.03MPa；
Further, water butt bottom is provided with blowdown valve；
In use in view of water butt, sundries is in water butt bottom to water pump safe handling in water for the utility model
Image, the sediment in water butt, which increases, can block pump intake, the safety and drainage equipment of serious image water absorber
Safe operation, therefore water butt lower part is provided with blowdown valve, the deposit of easy cleaning water butt bottom.
The utility model takes the one cylindric water butt of installation between suction hose and water pump, and installation is come into operation for the first time
When water butt need to fill to water, start and water butt filled into water before water pump, due to being higher than water pump at the top of mounted water butt, when
Pump chamber is also necessarily full of water when water butt is filled with water, therefore air cannot be introduced into pump chamber, installs for the first time or needs to open after repairing
Vent valve on pump is deflated, and no cavitation generates, No leakage point.After water pump starting draining, the water in water butt, which is sucked, to be caused to store up
Bucket negative pressure, the water in absorbing well, absorption well are pressed into water butt by suction hose under the action of external atmosphere pressure and enter pump chamber.Water
After pump is shut down, since suction hose is higher than water butt, water butt fills water always, when next time starts, without filling the water again.
The utility model has the advantages that the utility model provides a kind of coal mine underground draining device, economic, peace can be realized
Entirely, it reasonably runs, which can guarantee that air cannot be introduced into pump chamber, and no cavitation generates, and No leakage point passes through introducing
Water butt automatic water-leading and use multifunctional control valve replace non-return valve, motor-driven valve etc., so that the drainage efficiency of water pump is improved,
Guarantee that water pump is safely and efficiently run simultaneously.
