Embodiment Construction
[0051] This embodiment provides a hydrodynamic lifting device based on artificial waves, such as figure 1 As shown, it includes a motor 1, a crankshaft 2, a floating bracket (not shown), a connecting wire 3, a pulley 4 and a buoy 5, the floating bracket can float on the water surface, the motor 1 and the pulley 4 are installed on the floating bracket, and the crankshaft 2 is fixed On the motor 1, driven by the motor 1 to rotate, one end of the connecting wire 3 is connected to the crankshaft 2, and the other end goes around the pulley 4 to connect with the buoy 5 located under the floating support. Driven by the motor, the buoy 5 moves up and down to make waves. The chassis of the buoy 5 can be round or square. figure 1 is round.
[0052] This embodiment also provides a performance test method of the above-mentioned hydrodynamic lifting device, and specifically provides two test methods, one is to test with a reduced physical model, and the other is to test with a mathematica...

The invention discloses a water power lifting device based on artificial wave making, and further discloses two performance testing methods of the water power lifting device. The water power lifting device comprises a motor, a crankshaft, a floating support, a connecting line, a pulley and a buoy. The motor and the pulley are mounted on the floating support. The crankshaft is fixed to the motor. One end of the connecting line is connected with the crankshaft, and the other end of the connecting line bypasses the pulley and is connected with the buoy located below the floating support. One performance testing method adopts a physical shrinking model, and the other performance testing method performs numerical simulation by adopting a mathematical modeling. By means of the water power lifting device, water power improvement within a certain area is achieved, the adopted test method accurately quantifies the improvement effect of a weak water power area after device running, and a decision basis is provided for scientific and economic operation of a water power device as well as the improvement of riverway water power conditions.
Description
technical field [0001] The invention relates to water conservancy technology, in particular to a hydrodynamic lifting device based on artificial waves and a performance testing method thereof. Background technique [0002] With the development of water conservancy, gates and dams have been built in many places. On the one hand, gates and dams can effectively prevent floods and drain waterlogging, resist salty water and store fresh water, and irrigate and supply water, but on the other hand, they hinder the connectivity of water flow, resulting in poor hydrodynamic conditions , Not only is it not conducive to the transfer of pollutants, it is easy to lead to the deterioration of the water quality of rivers and lakes, and "a pool of stagnant water" cannot meet people's needs for the vivid beauty of "babbling water". Therefore, it is necessary to adopt artificial measures to improve the hydrodynamic conditions in the local weak dynamic area of the river. [0003] With the vi...
