Embodiment Construction

[0057] This embodiment provides a hydrodynamic lifting device based on water pump jet, including several water pump jet pushers, such as figure 1 and figure 2 As shown, the water pump jet pusher includes a base plate 1, a baffle plate 2, several buoys 3 (2 in the figure) and some water pumps 4 (5 in the figure); the buoys 3 are arranged on both sides of the base plate 1, and the base plate 1 The other two sides are empty, and the buoy 3 is fixed by connecting rods so that water can enter the bottom plate 1. The buoy 3 is connected with several anchors 5 by anchor ropes. For better stability, four anchors 5 can be set, which are respectively installed on The four corners of the outer bottom of the buoy 3; the water pumps 4 are horizontally installed on the bottom plate 1 side by side, and the water inlet of each water pump 4 is connected with a water inlet pipe 6, and the length of the water inlet pipe increases from the middle position to both sides in order to meet the flow ...

Abstract

The invention discloses a hydrodynamic lifting device based on water pump jet flow and its performance testing method and application. The device includes several water pump jet flow pushers, and the water pump jet flow pusher includes a bottom plate, a water baffle, several buoys and several water pumps , the buoys are arranged on both sides of the bottom plate, the buoys are connected with several anchors through anchor ropes, the water pumps are installed side by side on the bottom plate, and the water inlet of each water pump is connected with a water inlet pipe, the length of the water inlet pipe is Incrementing from the middle position to both sides, the water outlet of each water pump is connected with a water outlet pipe, all the water outlet pipes have the same length, the water baffle is vertically fixed on the bottom plate, and separates the water inlet pipe and the water outlet pipe on both sides of the baffle. 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 operated, so as to operate the hydrodynamic device scientifically and economically and improve the river course Hydrodynamic conditions provide the basis for decision-making.

Description

technical field [0001] The invention relates to water conservancy technology, in particular to a water pump jet-based hydrodynamic lifting device, its performance testing method and its application in water quality improvement. 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 mee...
