Problems solved by technology
[0003] The technical problem to be solved in the present invention is: the existing circulation water lifting device for aquaculture, the water pump head is relatively large, and the flow rate is small. For large-scale aquaculture water bodies such as pond farming and reservoirs, the existing water lifting device often has high power consumption , the energy efficiency is low, which not only causes energy waste, but also the stability of the water flow is not high, and the water lifting effect is poor

The invention relates to a low-lift and high-flow water lifting device for aquaculture water circulation. A water barrier (1) divides the aquaculture water body into a low water level side and a high water level side; It communicates with the water lifting device (2); the water lifting device (2) has a vertical cement guide seat, and a floating sleeve is arranged inside the cement guide seat, and the floating sleeve follows the water level of the high water level side. The height is free to float up and down; the upper end of the floating sleeve is fixedly connected with the horizontal strut (205), and the rotary power mechanism is fixed on the strut (205), and the output end of the rotary power mechanism is connected with the impeller (204) , the impeller (204) is located in the floating sleeve and provides water lifting power; the end of the strut (205) is fixedly connected with the fixed pile on the bank through a rope, and the rope provides the rotational resistance torque for the rotating power mechanism .
Description
Technical field [0001] The invention relates to a water lifting device, in particular to a low-lift and large-flow water lifting device for aquaculture water circulation, belonging to the technical field of aquaculture equipment. Background technique [0002] Aquaculture water circulation systems often require the application of water body lifting devices, which use pumps to increase the potential energy of the water body, thereby providing power for the water circulation. The existing water lifting devices generally use ordinary water pumps, but ordinary water pumps generally have a large lift and a small flow rate. It is widely used in small and medium aquaculture circulation systems, such as factory aquaculture ponds and pond aquaculture. However, the existing large-lift water lifting devices tend to have high power consumption and low energy efficiency. Causes energy waste, and the water flow stability is not high. How to solve the circulation of large-scale aquaculture wate...
