Abstract

The invention belongs to the field of novel renewable energy technologies and ocean equipment, and particularly relates to a semi-submersible type wave energy-wind energy comprehensive utilization device. The semi-submersible type wave energy-wind energy comprehensive utilization device comprises four float bowls, a wind turbine, two swing plates, depressed plates, anchor chains, a tower support, cross struts, inclined struts, rotation shafts and electric generators. The semi-submersible type wave energy-wind energy comprehensive utilization device is characterized in that the float bowls are fixedly connected with one another by adopting the cross struts and the inclined struts; the bottoms of the float bowls are connected with holding power anchors through the anchor chains and then fixed on the seabed; the swing plates are installed among the float bowls and face the direction of arrival of waves; the swing plates are connected with the electric generators through the rotation shafts and drive the electric generators; the wind turbine and the tower support are installed in the center of the float bowls. The semi-submersible type wave energy-wind energy comprehensive utilization device adopts the design that the front swing plates and the back swing plates work simultaneously, and the space between every two swing plates can be designed according to sea area wave characteristic parameters to improve the stability of a floating platform; the design of the depressed plates is adopted to improve the stability of the floating platform; eight catenaries are adopted to fix the integrated system on the seabed, and the safety is high; the form is simple, and installation and transfer are convenient.

Description

technical field [0001] The invention belongs to the field of novel renewable energy technology and marine equipment, in particular to a semi-submersible wave energy-wind energy comprehensive utilization device. Background technique [0002] Marine energy usually refers to the renewable natural energy contained in the ocean, mainly tidal energy, wave energy, ocean current energy (tidal current energy), seawater temperature difference energy and seawater salinity difference energy. Ocean energy in a broader sense also includes wind energy over the ocean, solar energy on the ocean surface, and marine biomass energy. The reason for this is that tidal energy and tidal current energy come from the gravitational changes of the sun and moon on the earth, and the others are all from solar radiation. Ocean energy can be divided into mechanical energy, thermal energy and chemical energy according to the storage form. Among them, tidal energy, ocean currents and waves are mechanical e...
