Tidal current generator

Abstract

The invention relates to a tidal current generator and, more particularly, to a tidal current generator capable of effectively generating electricity by being divided into a generation means on the water and an underwater power acquiring means. The tidal current generator can not only be easily managed on the water by being easily towable on the water even when a facility disposed underwater fails, but can maximally utilize a flow of tidal current through a connection line and a groove structure defined in a rotating propeller. By controlling the number of power connections between a rotationmeans and the generator on the water according to the flow of tidal current, the tidal current generator can maximize efficiency without waste and deficiency in power transmission.

Description

technical field [0001] The invention relates to a tidal current generator. Specifically, it relates to a tidal current generator, which separates the power generation device on the water from the power acquisition device in the water, can generate electricity efficiently, and can easily carry out traction on the water even if the facility in the water fails, and can carry out power generation on the water. It is easy to manage, and can maximize the use of the flow of the tidal current through the groove structure formed on the rotating propeller and the connecting rope, and control the number of power connections between the rotating device and the water generator according to the change of the flow state of the tidal current , thereby eliminating waste or insufficiency in power transmission, thereby enabling maximum efficiency. Background technique [0002] A power generation system that produces electricity can be realized in various ways. Thermal power generation uses f...

AI Technical Summary

Problems solved by technology

[0008] Despite the above-mentioned advantages, for the existing tidal current generator system, there is a disadvantage that it is inconvenient to repair it when the rotating propeller (blade), connection bearing and other facilities in the water fail

This is because in the water, the facility is always kept in rotation relying on strong currents, and it is difficult for operators to even approach

[0009] Not only that, the cross-sectional area of ​​the driving force generating part in the existing rotating propeller structure will generate a lot of eddy currents, which cannot normally receive the flow of the tidal current, so its efficiency will decrease

In addition, the flow of the tidal current constantly changes depending on the situation and terrain, and the power generation efficiency becomes unstable every time, which leads to poor productivity of the tidal current generator as a whole.
