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.
