The invention relates to a combined water-driven water pumping device used in rivers and depending on water flow power, in particular to a combined type water-driven water pump for the rivers. The combined type water-driven water pump for the rivers comprises a water wheel assembly, a water pipe connector, a support assembly and a water lubricated bearing. The water lubricated bearing is installed in the support assembly. The water wheel assembly is installed on the water lubricated bearing and located on the front portion of the support assembly. The water pipe connector is fixedly installed on the back portion of the support assembly through pipe threads. The water pipe connector is connected with a water pipe. The combined type water-driven water pump for the rivers has the advantages of being novel in structure, easy and convenient to machine, rapid and convenient to install, stable and reliable in work, free of being equipped with a power source and the like. In this way, the combined type water-driven water pump for the rivers is a novel combined type water-driven water pump for the rivers and integrates economical efficiency and practicability.
Description
technical field [0001] The combined hydrodynamic pump for rivers according to the present invention relates to a combined hydrodynamic pumping device used in rivers and rivers relying on water flow as power. Background technique [0002] Conventional water pumps generally need to provide additional power to drive the water pump to pump water, and it is often difficult to ensure a continuous and stable power supply in remote areas, which limits the application of water pumps. In addition, the use of electric water pumps also needs to consider issues such as sealing and leakage. The structure of the existing water pump is relatively complicated, and the manufacturing cost is relatively high. For the water pump that runs continuously for a long time, its power consumption is very considerable, and the operation cost is expensive. [0003] For the problems existing in the above-mentioned prior art, it is very necessary to study and design a novel combined hydrodynamic pump for ...
