Background technology
Mine gas accident is one of natural calamity the most serious in the coal production.Along with the increase of the pit mining degree of depth, the difficulty of control of coalmine gas is increasing, and it is increasing that the most obvious feature is exactly coal-bed gas pressure and content, and it is very crucial for Comprehensive Gas Control how to determine fast and accurately coal-bed gas pressure.Coal-bed gas pressure is the power that gas springs up from the coal seam, also is the sign of coal seam gas-bearing capacity.Traditional coal-bed gas pressure measurement technique is the pressure measuring drill hole of constructing in the coal seam first, then draws piezometer tube and be communicated with the gas pressure checkout gear from pressure measuring drill hole.But be full of gas and water in the pressure measuring drill hole in traditional pressure measurement technique, gas pressure is subject to the impact of hydraulic pressure, is difficult to the pressure that Accurate Determining goes out gas in the real coal seam.So design and research and development are the gas pressure measurement device more reasonably, is implemented under the prerequisite that does not affect pressure test, discharges timely and effectively the pressure measuring drill hole internal water accumulation, becomes a problem demanding prompt solution.
The utility model content
The purpose of this utility model is, detects the problem that is subject to ponding impact in the pressure measuring drill hole for above-mentioned existing gas pressure, proposes a kind of positive-pressure water draining device, to be implemented under the prerequisite that does not affect the gas pressure test, discharges timely and effectively ponding in the pressure measuring drill hole.
For achieving the above object, the technical solution adopted in the utility model is: a kind of positive-pressure water draining device, comprise storage tank, and be provided with water inlet and delivery port on the described storage tank, arranging of described water inlet highly is higher than delivery port, is respectively arranged with the control gate valve on described water inlet and the delivery port.
Further, described control gate valve is ball valve.
Further, be provided with visual window on the described storage tank.
Further, described storage tank is the tubbiness storage tank.
Further, be provided with base for supporting below the described storage tank.
Another purpose of the present utility model provides a kind of gas pressure checkout gear, can realize convenience, accurately pressure measurement.
For achieving the above object, the technical solution adopted in the utility model is: a kind of gas pressure checkout gear, comprise above-mentioned positive-pressure water draining device, and the water inlet of described positive-pressure water draining device is communicated with pressure measuring drill hole.
The operating principle of the utility model positive-pressure water draining device: the positive-pressure water draining device water inlet is communicated with pressure measuring drill hole by pipeline.Water inlet control gate valve is opened when initial, and delivery port control gate valve is closed, and the ponding in the pressure measuring drill hole enters storage tank from water inlet, and ponding constantly accumulates, the existence of this pressure of invar, and the pressure in the storage tank is greater than atmospheric pressure; When ponding reaches designated water level in the storage tank (as being full of), close the control gate valve of water inlet, open delivery port control gate valve, the ponding in the storage tank is discharged under the effect of gas pressure.After the ponding discharging is complete, close delivery port control gate valve, open water inlet control gate valve, the ponding in the pressure measuring drill hole enters storage tank from water inlet, so moves in circles, and dynamically discharges water.
The design of the utility model positive-pressure water draining device is light, and compact conformation is portable; Principle is simple, installation, convenient disassembly; Can realize the holing storage of ponding and in time discharging, economic benefit is obvious.The utility model gas pressure checkout gear can discharge the ponding in the pressure measuring drill hole timely and effectively, so that the pressure of measuring truly reflects the gas pressure in coal seam.
