The application relates to the technical field of pressure boosting
water delivery, in particular to a dam bottom air-closed pressure boosting
water delivery device, which comprises a pressure boosting
water delivery device, a main liquid chamber is arranged in the middle of the pressure boosting water delivery device, an air-
closed chamber and a first water delivery chamber are arranged in the pressure boosting water delivery device and are in internal communication, and the main liquid chamber is in internal communication with the air-
closed chamber. The purpose of the application is: when the pressure of the main liquid chamber is greater than that of the second water delivery chamber, the
pressure difference drives the liquid to flow into the second water delivery chamber and to flow to the conveying
pipe, the water gate controls the liquid flow in the first water delivery chamber to guarantee the smooth
pressure transmission, the liquid level is monitored in the
stroke switch in the circulation, the air-
closed chamber liquid level is closed-loop controlled through linkage of the water gate and the
air pump, the device is driven by the dam
water source, realizes the circulation pressure boosting water delivery without additional power, can realize the cross-region and long-distance
water body allocation and delivery through
pipe network construction, effectively alleviates the water resource shortage problem in
arid regions, and helps to develop the water shortage wasteland into
arable land.
