Description

Technical Field

[0001] The utility model relates to the technical field of hydropower generation, in particular to a floating hydropower station. Background Technique

[0002] A hydropower station (also known as a hydroelectric power station or a hydropower plant) is a facility that uses the kinetic energy and potential energy of water flow to generate electrical energy. It is usually built in the nearshore areas of rivers, lakes or oceans with rich water resources. A floating hydropower station utilizes the kinetic energy of water flow or waves and converts it into mechanical energy through a specific mechanical structure (such as a turbine or piston system). The obtained mechanical energy further drives a generator to convert the mechanical energy into electrical energy, and then transmits it to the power grid through a cable.

[0003] Traditional floating power generation equipment floats a draft tube with a turbine generator on the water surface through a floating drum. When water flow passes through the draft tube, its kinetic energy drives the turbine to rotate, and then drives the generator to generate electricity, realizing the process of converting the kinetic energy of water flow into electrical energy. Since there may be sundries, garbage, etc. floating in the water flow, these objects are likely to enter the draft tube along with the water flow, which may block the turbine or damage the turbine blades, thus affecting the normal operation of the turbine generator. Moreover, when it is necessary to expand the scale of the power generation equipment, it is not convenient to assemble and connect multiple units, and the flexibility and scalability are not high.
