Technical Field

[0002] During the mining process of coal mines, it is necessary to drain the water in the water reservoir in the mine. In the current prior art, coal mines mostly use diaphragm pumps for drainage. Diaphragm pumps use compressed air as power to drain water, and have the advantages of easy installation and installation, and small size. However, there are the following shortcomings in using diaphragm pumps for drainage: after the diaphragm pump is installed, it is necessary to manually turn the air valve to drain water. When the water in the water reservoir is drained, the air valve needs to be manually closed to stop the diaphragm pump. The entire process requires personnel to operate and monitor. If the diaphragm pump is not turned off for a long time after the water in the pool is drained, the diaphragm pump will be damaged due to lack of water. Therefore, the utility model proposes a driver-controlled diaphragm pump automatic drainage device to solve the shortcomings of the prior art. Utility Model Content
