Wind wave and oscillation-combined floater power generation device adaptable to ice periods and power generation method

Abstract

The invention discloses a wind wave and oscillation-combined floater power generation device adaptable to ice periods and a power generation method. The device comprises a single-pile foundation installed at seabed and extends out of sea surface; an anti-icing cone is installed at the intersection of the single-pile foundation and the sea surface; the top of the single-pile foundation is providedwith a tower tube; the top of the tower tube is provided with a horizontal axis wind turbine; electricity generated by the wind turbine is integrated into a power grid through a power transmission circuit; a sleeve is fixedly installed on a portion of the single-pile foundation which extends out of the sea surface; the sleeve sleeves the single-pile foundation; an annular platform is arranged at the upper part of the sleeve; two or more energy conversion systems are arranged on the annular platform; the number of the energy conversion systems is the same as the number of first connection devices; electricity generated by the energy conversion systems is transmitted to the tower tube; and the sleeve is circumferentially provided with the first connection devices at equal intervals below theannular platform, wherein the first connection devices are equal in height; and floaters of the same number with the first connection devices are arranged on the sea surface. According to the power generation device disclosed by the invention, the wave energy generating device and the wind turbine are combined, and therefore, cost can be effectively reduced, and the utilization rate of sea spaceand resources can be improved; and wind energy and wave energy are simultaneously collected for power generation, and the complementation of power in a complex environment is realized.

Description

technical field [0001] The invention belongs to the field of comprehensive utilization of wind energy and wave energy for power generation, and in particular relates to a wind wave combined with oscillating float power generation device and a power generation method suitable for ice ages in the field. Background technique [0002] With the gradual reduction of non-renewable energy and the excessive emission of greenhouse gases causing more and more harm to the earth's environment, increasing the development of clean and pollution-free renewable energy has become one of the important topics that are generally concerned by countries all over the world. The vast ocean area on the earth has infinite energy. In addition, the continuity of energy also makes it have unlimited development potential. There are various forms of ocean energy, and the development and utilization methods of different types of ocean energy are also different, but most of them are concentrated in the field...

Problems solved by technology

Wave energy has the advantages of abundant reserves, wide distribution, high power density, and local availability. It is one of the research hotspots in the field of renewable energy today, but the electric energy it generates is unstable and discontinuous; wind energy as a Clean and pollution-free renewable energy has been used by people for a long time. Although the power density is not as good as wave energy, wind energy is continuous within its usable range. Compared with land, the wind energy resources in the sea are more abundant. There are certain complementary characteristics in time and space
