Description

The sea structure of wind power generator

The present invention relates to a wind power offshore structure that is installed on water of a river or sea shore to obtain power by using wind.

In general, electricity is a thermal power plant using Mars fuel, a hydro power plant using water, and a nuclear power plant using nuclear reactors. Recently, tidal power plants using a tidal wave and wind power generation using wind have been developed and provided.

The thermal power plant is to obtain the electrical energy by burning the Mars fuel, there is a problem of global warming and exhaustion of Mars fuel by exhausting a large amount of carbon dioxide during the combustion of the Mars fuel, the hydro power plant is a strong There is a disadvantage in that the installation place is limited, and the nuclear power plant has a disadvantage in that it is not easy to install because there is a danger of radiation and there is a lot of costs and a backlash against local residents.

The tidal power plant should be installed in a place where the difference between tides occurs, and there is a disadvantage in that the algae change during installation to cause the deformation of the ecosystem and the shore.

The wind power generation using the wind has the advantage that can solve all the disadvantages of other power plants, but it has the disadvantage of increasing the installation cost by occupying the land when installed on land, especially when the area of the country is small, such as Korea There is a sense of independence.

In addition, the wind power generation using the wind can be a continuous generation of continuous wind blows, but in the case of land has a problem in finding a place where the continuous wind blowing enough to generate wind power.

Wind power generators for generating wind power in general to rotate the rotary shaft by the rotary blades rotated by the wind, and to generate power (electricity) by rotating the shaft of the generator connected to the rotary shaft, as shown in Figure 8 stably on the ground or structure A support 1 installed vertically, a rotation support 2 installed to rotate above the support 1, a rotation shaft 3 installed to rotate on the rotation support 2, and the rotation shaft 3 It consists of a plurality of rotary blades (4) installed in the orthogonal direction and the rotary support (2) inside, and connected to the rotary shaft (3) to generate a power generator (not shown).

The rotary blade is usually installed twisted at a predetermined angle so as to be rotated by the wind, there is a disadvantage that does not properly cope with the size (strength) of the wind.

In other words, the size of the wind changes according to seasons or typhoons as in Korea, but the conventional wing does not cope with this, and if the wind is weak, the rotating shaft cannot be rotated. Rotating quickly has the disadvantage of damaging the generator or breaking the wings, supports and the like.

Therefore, in order to protect the rotor blades from strong winds, the width of the wing is not increased, so it does not rotate well in the weak winds, and there is a disadvantage in that it cannot continuously supply power.

In addition, when too strong wind blows, there is a disadvantage that the operator has to manually fix so that the rotor blade does not rotate and there is a disadvantage that does not generate power (power).

Wind power generation marine structure of the present invention invented to solve the above problems, is installed on the water of the river or the coast where the wind continuously blows better than land, wind power offshore marine power having a power generator using the wind power to obtain power for the wind The purpose is to provide a structure.
