[0002] Hydraulic dam refers to a hydraulic concrete lifting dam, which is a relatively simple movable dam technology in water conservancy technology. It is widely used in agricultural irrigation, fisheries, ship locks, seawater tidal barriers, urban river landscape projects and small hydropower station construction.

[0003] If the water volume is too large, the height of the traditional hydraulic dam may not be adjusted in time, resulting in the inability to effectively intercept the upstream water flow, thereby increasing the possibility of impact and damage to the downstream area. In addition, when the traditional hydraulic dam needs to measure the flow, it may not be able to stably fix and clamp the flow meter, resulting in the flow meter being washed away due to excessive water flow during flow measurement, thereby reducing the stability and accuracy of the measurement. Therefore, it is necessary to design a hydraulic dam with adjustable height. Utility Model Content
