Marine floating-type power station capable of utilizing wind energy, ocean current energy and wave energy

Abstract

The invention relates to a novel marine power station, especially involves a marine floating-type power station capable of utilizing wind energy, ocean current energy and wave energy. The structure comprises: a central pontoon, a suspension cabin, a universal elastic support, a wind turbine, a wave power plant, a connecting arm, a stabilizing pontoon, a water turbine, an energy storage device, an electricity generation system, etc. The power station employs a H-type vertical shaft wind wheel in major diameter and low height and a structure of upper-light, lower-heavy and elastic support in the middle, therefore the power station can float and be fixed on the sea; the power station also employs a centralized hydraulic pressure storage device consisting of an accumulator and a fuel tank, and a parallel-type generating system consisting of a plurality of generators and hydraulic motors, so as to guarantee the generating efficiency and the constant frequency under the condition of low wind speed, low flow velocity and small waves; the power station is suitable for the comprehensive utilization of deep sea wind energy, wave energy and ocean current energy resource.

Description

technical field [0001] The invention relates to a novel offshore power station, in particular to an offshore floating wind-force ocean current and wave power station. Background technique [0002] The ocean is a treasure land of energy storage on the earth, containing abundant wind energy, wave energy and ocean current energy resources. Offshore wind energy resources, as a clean and renewable energy source, have huge reserves. The exploitable offshore wind energy resources in the east coast of China amount to about 750 million kilowatts; According to ocean observation data, the total amount of wave energy resources is about 500 million kilowatts, and about 100 million kilowatts can be developed and utilized; China is also rich in ocean current energy, and the theoretical average power along ocean currents is 140 million kilowatts. [0003] The use of ocean energy is the direction of energy research in the world today, especially in the situation where energy is related to n...
