Abstract

The invention discloses a wave energy power generation unit and a system based on a sea-surface wave region and a deep sea stable region. The wave energy power generation unit comprises a sea surface floating platform, a power generation set, a transmission mechanism and a water turbine, wherein the power generation set is fixed on the sea surface floating platform; the floating platform floats on the sea surface; the rotating input end of the power generation set is connected with the water turbine through the transmission mechanism; and the water turbine is placed in the deep sea stable region. When the water turbine is vertically pulled up by the floating platform or moves down due to gravity, under the guide action of an upper blade layer and a lower blade layer, the flow unidirectionally affects a worm wheel of the water turbine, so that the worm wheel in the middle of the water turbine unidirectionally rotates and drives a transmission rod connected to the floating platform through a cardan joint and a water turbine rotor to synchronously rotate. Turning force is transmitted to a generator rotor on the sea surface, thereby driving the generator to rotate and converting the sea wave energy into the electric energy.

Description

technical field [0001] The invention belongs to the technical field of green energy power generation, and in particular relates to a wave energy power generation system based on differential energy extraction of ocean wave energy in a sea surface wave layer and a deep sea stable zone. . Background technique [0002] Ocean energy is clean and renewable energy, including tidal energy, wave energy, temperature difference energy, ocean current energy, and salt difference energy. Among them, wave energy refers to the kinetic energy and potential energy of sea surface waves produced by interstellar motion and day-night temperature changes. It is the largest energy that can be developed and utilized in marine energy, mainly as follows: [0003] (1) Ocean wave energy appears in the form of kinetic energy and potential energy. Generally speaking, waves are divided into two types. One type is waves closer to the shore, called inshore waves. On the coast, since the ups and downs of...
