The utility model provides an automatic liquid level measuring device for a reverse drainage tank of a coal seam drainage well. The automatic liquid level measuring device comprises a floating ball, a fixed pulley block, a plumb bob and a liquid level ruler, the floating ball penetrates through the fixed pulley block through a connecting rope to be connected with a plumb bob. And the height of the liquid level in the reverse drainage tank is read from the liquid level scale corresponding to the plummet. The pulley type automatic liquid level measuring device is researched and developed, potential safety hazards existing in the process of measuring the liquid level in an upper tank in the prior art are avoided, the labor intensity of drainage and mining personnel is reduced, measuring errors are reduced, and automatic measurement of the tank level is achieved. And meanwhile, remote observation can be realized in cooperation with view screen monitoring, and finally intelligent drainage and mining are realized.
