Abstract

The invention relates to a wind energy and ocean energy integrated generating set. The generating set comprises a tidal current energy driven generating set and a wave power driven generating set, wherein the tidal current energy driven generating set is arranged below the sea level and comprises a turbine and a rigid supporting frame; the turbine comprises an impeller rotating horizontally; the impeller is provided with a through hole; a vertical shaft is arranged on the rigid supporting frame; the impeller sleeves the vertical shaft via the through hole; the wave energy driven generating set comprises an oscillatory type floater; the oscillatory type floater is connected with the upper part of the vertical shaft and is positioned on the sea level. According to the wind energy and ocean energy integrated generating set disclosed by the invention, the impeller and the oscillatory type floater are together arranged on the same vertical shaft, so wave energy and tidal current energy can be transformed into kinetic energy of the vertical shaft; meanwhile, the power supplied to the impeller and the oscillatory type floater is increased, and energy transformation ratio is increased.

Description

technical field [0001] The invention relates to the field of ocean energy utilization, in particular to a wind energy and ocean energy comprehensive power generation device. Background technique [0002] With the consumption of non-renewable energy such as oil and coal, people gradually consider how to make full use of the energy on the ocean, and the wind energy, tidal current energy, and wave energy on the ocean are endless renewable resources and non-polluting green energy. The technology of using wind power to generate electricity at sea is mature. However, compared with offshore wind power generation, the energy conversion rate of wave energy generation devices and tidal current generation devices is lower, and the unit power generation cost is higher, which limits the full utilization of the two to a certain extent. Therefore, how to make full use of wind energy, tidal current energy and wave energy, and use the same device to generate electricity has been a research t...
