Abstract

The invention discloses a high-reliability automatic water discharging device of a coal-bed gas extraction pipeline. The problem that an existing automatic water discharging device of a coal-bed gas extraction pipeline is low in reliability is solved. A two-working-station air valve (8) is arranged in a water collecting tank (3), an annular tray (18) is arranged on the lower part of a jacking rod(17), a float (29) is movably connected to the position, on the upper part of the annular tray, of the jacking rod, a rod-pulling frame (19) is fixedly arranged on the position, on the upper part of the float, of the jacking rod, and a V-shaped swing arm connecting pin (20) is arranged on the position, on the upper part of the rod-pulling frame (19), of the jacking rod; a V-shaped swing arm mechanism is arranged on the position, on the right side of a U-shaped frame (15), of a bracket plate (7), a counterweight (23) is connected to the position, on the right side of a V-shaped swing arm (22),of the outer end of the swing rod, a C-shaped hook pin shaft (27) is arranged on the position, under the V-shaped swing arm, of a C-shaped hook pin shaft fixing frame (28), and a C-shaped hook (26) ishinged to the C-shaped hook pin shaft. The high-reliability automatic water discharging device acts reliably in the downhole dusty and watery environment.

Description

technical field [0001] The invention relates to a water collection and discharge device on a coalbed gas extraction pipeline, in particular to an automatic water collection and discharge device arranged on an underground coalbed gas extraction pipeline in a coal mine. Background technique [0002] Coalbed methane, also known as gas, is a type of natural gas that exists in coal seams and is an associated product of coal. Co-mining of coal and gas is an inevitable way to exploit coal resources. It can not only improve the safety level of coal mine production, but also optimize The energy structure is of great significance to the effective utilization of coal mines and resources; during the process of extracting gas underground, rock formation fissure water will enter the coalbed methane extraction pipeline along the borehole, causing water accumulation in the coalbed methane extraction pipeline, resulting in gas extraction. The mining system is blocked; at present, water relea...
