Description

Tidal power generating system,

The present invention, half relates to a submerged buoyancy of bird, can flow generation systems and, more particularly, a compact yet available in efficient algae water flow turbine structure to produce electric power by using the water flow it it is possible to improve the power generation efficiency as well as The present invention relates to an economical semi-submerged buoyant bird and water power generation system that can be conveniently installed or maintained.

As a power generation system using water, a hydroelectric power generation system has been used in which a dam is installed and a turbine is rotated by increasing water pressure and giving a drop.

However, this method not only causes natural destruction but also causes great environmental problems. Therefore, development of technology for environmentally friendly tidal current and water current generation using water flow has been demanded and technology development has been started.

Tidal power generation is a kind of renewable energy. Tidal resources generated by tides are abundant and constantly recycled. They are distributed in a wide area and are clean. In addition, Is an available energy source that stands out as a promising alternative energy source for depletion of fossil fuels. The Republic of Korea is a peninsula consisting of three oceans and has abundant coastal marine algae resources.

Algae development is an infinite clean natural energy caused by the man power of the solar system. As long as the solar system is present, the tidal phenomenon prevails in the coastal waters of the southwestern coast of Korea. When a flow velocity occurs, a large amount of electric power can be stably generated.

The characteristic of tidal power generation is that since seawater uses seawater having a density of about 840 times that of air, the generation amount is proportional to the density, so even if a small turbine (vertical turbine) is used, have.

Unlike tidal power generation, tidal power generation is advantageous in that it does not need a dam, it does not affect the surrounding coastal marine environment because it is generated by using the current of the tidal current and is free from seawater circulation.

In addition, tidal power generation is an eco-friendly power generation method in which the initial investment cost is lower than the tidal power generation, and it is installed in a region where the tidal current of the coastal area is fast, and is relatively low in investment cost compared to the tidal power generation. It is emerging as a good alternative energy source to reduce the use of fuel and to respond to the Convention on Climate Change through reduction of greenhouse gases. Natural tidal phenomena can be predicted in the long term and a great advantage of algae development is that it is a reliable and clean energy source that can accurately predict and generate electricity regardless of seasonal factors or weather.

Algae power generation can be classified into two types depending on the installation method: a settling type (horizontal type) and a floating type (vertical type).

In the case of the tidal-type horizontal axis tidal power generation, the propeller-shaped turbine is generally installed in the subsea underwater, and the initial investment cost is high and the main power generation facility is installed in the seabed water, making it difficult to operate and maintain. There is a problem that it is insufficient.

On the other hand, floating (vertical) tidal power generators are vertical tidal turbine generators. It is possible to place the key equipments and main power equipment equipments on the surface of the water, so that the installation investment cost is low, the maintenance operation is safe, the advantage of short installation period of the tidal generator and the low cost economical bird Power generation method.

The problem of the tidal power generation system using the floating tidal power generation, which has been known so far, is to solve the problem that the power generation efficiency is deteriorated due to the structural limit of the turbine due to the development of the vertical drag turbine technology, The need for
