Tidal current energy power generation device and using method thereof

Abstract

The invention provides a tidal current energy power generation device and a using method thereof, and belongs to the technical field of tidal current energy power generation. The tidal current energypower generation device comprises a vacuum water storage tank, a first channel, a second channel, a first pipeline, a second pipeline, a water inlet pipe and a vacuumizing mechanism, a partition plateis arranged in the vacuum water storage tank and partitions the vacuum water storage tank into a first cavity and a second cavity, the first cavity and the second cavity communicate through a gap, the first channel and the second channel are both formed in the vacuum water storage tank, a first through hole and a second through hole both communicate with the second cavity, the first pipeline is horizontally and fixedly arranged outside the first channel, the second pipeline is horizontally and fixedly arranged outside the second channel, the water inlet pipe is fixedly arranged on the vacuumwater storage tank, provided with a solenoid valve, and internally provided with a water flow power generator, and when the water inlet pipe, the first pipeline and the second pipeline are all completely submerged below the water surface, the vacuumizing mechanism can pump air in the first cavity and the second cavity. Tidal current energy can be fully utilized, and thus the power generation efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of tidal current energy power generation, and relates to a tidal current energy power generation device and a use method. Background technique [0002] Energy is the lifeblood of a country. As a basic energy source, conventional fossil energy has promoted the development of human civilization, but at the same time it will cause great damage to the natural environment. Global common problems such as the greenhouse effect, environmental degradation and energy shortage are already very serious. [0003] As a kind of green energy, ocean energy has become the object of research and development by countries all over the world because of its advantages such as good renewability, strong predictability, cleanness and environmental protection, and abundant reserves. Tidal current energy is a kind of ocean energy, which refers to the kinetic energy of seawater flow, mainly refers to the relatively stable flow in subm...

Problems solved by technology

[0004] The tidal current energy power generation system uses the horizontal flow of seawater to drive the impeller on the hydroelectric generator to rotate and then generate electricity. However, limited by the technology of the hydroelectric generator, it is difficult to drive the generator to generate electricity when the tidal current speed is less than 1.5 m / s. Therefore, most of the tidal current energy has not been utilized, making the power generation efficiency of tidal current energy much lower
