Embodiment Construction

[0022] The specific implementation manners of the present invention will be further described below in conjunction with the accompanying drawings and technical solutions.

[0023] Such as figure 1 As shown, the wind generator 1 is connected to the seabed through a tower 2, a semi-submersible platform composed of a buoy 4 and a column 6, and an anchor chain 3. The wind generator 1 rotates under the wind force, converts the wind force into mechanical energy, and then drives the wind generator 1 to generate electricity through the gear box. On the other hand, the water column 6 in the buoy 7 of the oscillating water column type wave energy generating device 5 reciprocates under the external force of undulating waves, which is then converted into the reciprocating motion of the gas in the air chamber 8, thereby driving the air turbine generator 10 generate electricity. The two-way air turbine generator is adopted, so the process of wave ups and downs can be used to generate elec...

Abstract

The invention belongs to the technical field of seaborne renewable energy utilization, and discloses a novel floating wind energy-wave energy combined electricity generation system. The system is based on a semi-submersible-oscillating water column wave energy integrated electricity generation platform without supporting stand columns, and comprises a seaborne wind electricity device and an oscillating water column wave energy electricity generation device. By means of the wave energy electricity generation device, vertical reciprocating motion of a water column is converted into reciprocating motion of a gas, and then electricity generation of wave energy is completed through an air turbine generator. According to the system, a bottom floating box and anchor chains of the semi-submersible platform are fully utilized; as the wave energy electricity generation device vertically moves with waves, the electricity generation efficiency is reduced, and the floating box can slow down vertical vibration; the anchor chains can further prevent the wave energy electricity generation device from vertically moving. According to the system, the structure of the supporting stand columns is not used, the construction process is simplified, and the problem of structural fatigue produced by the supporting stand columns is avoided. Compared with a traditional three-stand column semi-submersible blower, the waterplane area of the system is increased, thus steady moment of inertia is large, and the whole stability of a floating basis is improved.

Description

technical field [0001] The invention belongs to the technical field of marine renewable energy utilization, and relates to a novel floating wind energy-wave energy integrated power generation system, an integrated power generation system based on a semi-submerged floating platform that combines wind energy and an oscillating water column type wave energy device. Background technique [0002] Wind power is currently the most promising renewable energy source for large-scale development. Offshore wind power has become a new direction of international wind power development and has attracted the attention of all countries. As the proportion of offshore wind energy in the overall energy structure increases year by year, the development of floating wind turbine foundations suitable for deep water is also receiving more and more attention. However, the wave energy power generation device has low energy conversion efficiency and high unit power generation cost, which limits its co...
