Problems solved by technology

[0003] Most of the existing technologies use water diversion and drainage to control and improve the hydrodynamic conditions of the river. Occasionally, independent or series submersible pumps are used to improve the hydrodynamic conditions, but the effect is limited

Embodiment Construction

[0052] This embodiment provides a hydrodynamic lifting device based on vertical axis pushing flow, such as figure 1 As shown, it includes bracket 1, motor 2, pusher plate 3 and vertical shaft 4, motor 2 is fixed on bracket 1, motor 2 is connected to one end of vertical shaft 4, and the other end of vertical shaft 4 is fixed with pusher plate 3 , specifically fixed on the center line of the pusher plate 3, the pusher plate 3 is rectangular, and its length is 1 / 15 to 1 / 3 of the maximum radius of the hydrodynamically weak area, and the optimal value is 1 / 10 to 1 / 5, because The shape of the weak hydrodynamic area is uncertain, so the maximum radius at the area where the hydrodynamic lifting effect is desired is used as the measurement standard, and the maximum radius represents the value obtained by dividing the maximum diameter of the area by 2. The support 1 includes several struts and a table top fixed by the support of the struts. The height of the struts is greater than the d...

Abstract

The invention discloses a hydrodynamic lifting device based on vertical shaft push flow, which includes a bracket, a motor, a flow plate and a vertical shaft, the motor is fixed on the bracket, and the motor is connected to one end of the vertical shaft. The other end of the vertical shaft is fixed together with the pusher plate, the pusher plate is rectangular, and the length is 1 / 15 to 1 / 3 of the maximum radius of the hydrodynamically weak area. The invention also discloses two performance test methods of the hydrodynamic lifting device, one is to use a physical scale-down model, and the other is to use a mathematical model to perform numerical simulation. The hydrodynamic lifting device of the present invention realizes hydrodynamic lifting in a certain area, and the test method adopted also accurately quantifies the improvement effect of the weak hydrodynamic area after the device is in operation, so as to operate the hydrodynamic device scientifically and economically and improve the river course Hydrodynamic conditions provide decision-making basis.

Description

technical field [0001] The invention relates to water conservancy technology, in particular to a hydrodynamic lifting device based on vertical axis pushing flow and a performance testing method thereof. Background technique [0002] The running water does not rot, and the door hinge does not moth. In recent years, the natural hydrological conditions of many rivers have been artificially changed, resulting in significant changes in the hydrodynamic conditions of the rivers; especially the construction of too many gates and dams, although it is conducive to improving the utilization efficiency of water resources, it is easy to cause hydrodynamics in some areas of the river. The conditions have been greatly weakened, and the exchange capacity of water bodies is poor, which is not conducive to the migration and diffusion of pollutants in the rivers, which intensifies the pollution of water bodies and affects people's production and life. In order to meet people's needs for the ...
