Abstract

The invention discloses a marine power generation device. The marine power generation device comprises at least two bases, a power generator and blades, wherein bearings are arranged on the bases, a rotating shaft is arranged between each two adjacent bearings, and a rotor of the power generator is connected with the rotating shafts; the tabulate blades are uniformly mounted on the rotating shafts along the axial directions of the rotating shafts, and 3-8 blades are arranged on each rotating shaft; and an arc-shaped protecting cover is further arranged on the bases and is located above the rotating shafts and the blades, and the bottom end of the arc-shaped protecting cover is level with the rotating shafts. The marine power generation device provided by the invention is simple in structure and high in efficiency and has the power generation manners of tides and sea waves as well as wind power.

Description

technical field [0001] The invention relates to an offshore power generation device, which belongs to the field of clean and renewable energy development. Background technique [0002] In the vast sea, due to the wind and the gravitational force of the moon, there are waves of different sizes every day, which contain huge energy, which is called tidal energy. The main utilization method of tidal energy is tidal power generation. The principle of tidal power generation is similar to that of ordinary hydropower generation. By going out of the reservoir, seawater is stored in the reservoir at high tide and stored in the form of potential energy. Then, seawater is released at ebb tide to utilize high, The drop between the low tide levels drives the water turbine to rotate and drives the generator to generate electricity. Tidal power generation has the characteristics of rich resources, large reserves, renewable, etc., and is environmentally friendly and pollution-free. The exi...
