Abstract

The invention discloses a power generation device capable of comprehensively utilizing wave energy and ocean current energy. The power generation device comprises a floater, a differential integrationmechanism, an ocean current energy collecting mechanism, a wave energy collecting mechanism and a power generation mechanism, wherein the floater floats on the water surface, the power generation mechanism is arranged in the floater, the ocean current energy collecting mechanism and the wave energy collecting mechanism are sequentially arranged below the floater, the bottom of the floater is provided with a shell used for installing the differential integration mechanism, the ocean current energy collecting mechanism and the wave energy collecting mechanism collect mechanical energy, the mechanical energy is integrated through the differential integration mechanism and then is transmitted to the power generation mechanism for power generation, the ocean current energy collection mechanismcomprises a ocean current energy power shaft, a support frame and an one-way circulation surface, wherein the ocean current energy power shaft is mounted on the lower part of the shell through a bearing in a supporting mode, and the ocean current energy power shaft is a hollow shaft for allowing the wave energy collecting mechanism to transfer power from the ocean current energy power shaft. According to the power generation device, the wave energy and ocean current energy in the ocean are comprehensively utilized, and the problems of single working mode and low energy utilization rate of a traditional offshore power generation device are solved.

Description

technical field [0001] The invention belongs to the field of power generation equipment, and relates to marine power generation equipment, in particular to a power generation device that comprehensively utilizes wave energy and ocean current energy, in particular to a power generation device that can simultaneously utilize the current energy of the wave horizontal plane and the potential energy in the vertical direction. Background technique [0002] The depletion of traditional energy sources and the deterioration of environmental pollution make it urgent to develop new energy sources. Compared with wind energy and solar energy technology, wave energy power generation technology is more than ten years behind. However, wave energy has its unique advantages. The energy density of wave energy is high, which is 4 to 30 times that of wind energy. Compared with solar energy, wave energy is not affected by the weather. Most of the existing electric energy is generated by coal-fir...
