DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wind turbine generator that generates power using wind power at sea or on a lake.

[0002]

2. Description of the Related Art Conventionally, as this type of offshore wind turbine, as shown in FIG. 7, for example, as shown in FIG. There is one in which a wind power generation unit 64 is integrally provided at the upper end of a vertical support 63 that protrudes.

[0003]

However, in the above-mentioned conventional type, there is a problem that it takes time to underwater foundation work (undersea civil engineering work) for installing and fixing the concrete block 62 on the seabed 61. Further, since the concrete block 62, the vertical support 63, and the wind power generation unit 64 are installed on the seabed 61 in a state where they are integrally assembled, there is a problem that workability is poor. Furthermore, since the depth of the sea varies depending on the sea area where the offshore wind turbine 65 is installed,
There is a problem that it is difficult to quickly adjust the height H of the floating wind turbine 65 to the depth of the sea.

[0004] It is an object of the present invention to provide a wind turbine generator that can be easily installed on the bottom of a water and can be quickly assembled at a height corresponding to the depth of the installation location.

It has a framed structure composed of a horizontal member and a rod-shaped diagonal member joined between the vertical support and each horizontal member, and each horizontal member submerged in the water bottom is a fixed member driven into the water bottom. Is fixed by

According to this, the horizontal members are sunk to the bottom of the water and the fixing members are driven into the bottom of the water, whereby each horizontal member is fixed to the bottom of the water, and the support portion is prevented from tipping over. Thereby, a water wind turbine generator is easily installed. Further, in the surface wind power generator according to the second aspect of the present invention, the vertical strut is constituted by a plurality of extendable struts.

Conversely, by reducing the number of pillars to be added, the height of the offshore wind turbine is reduced. By increasing or decreasing the number of pillars to be added in this way, the height of the surface wind turbine can be quickly adjusted according to the water depth of the installation location.

[0008] In the third aspect of the present invention, the wind turbine generator is provided with a plurality of artificial reefs submerged in the water bottom between each horizontal member. According to this, since fish gather on the artificial reef, it is possible to prevent the environment around the water wind turbine from deteriorating. Furthermore, since each artificial reef controls the lateral displacement of each horizontal member, even if the fixing member comes off the bottom of the water, the support portion is securely fixed in the horizontal direction.

[0009] In the fourth aspect of the present invention, each artificial reef is received by a cradle and installed on the bottom of the water.
In each of the receiving pedestals, a biting portion that cuts into the water bottom is formed. According to this, the artificial reef is firmly fixed to the bottom of the water through the cradle by the biting portion of each cradle digging into the water bottom, and does not shift laterally.

[0010] In the surface wind power generator according to the fifth aspect of the present invention, a horizontal flange portion is formed on each pedestal so as to project outward, and each horizontal member is provided on a flange portion of the cradle located on both sides of the horizontal member. It is placed on. according to this,
In addition to the weight of the artificial reef, the weight of the wind power generation part and the support part is applied to each pedestal via the flange part, so that each pedestal is pressed against the water bottom with the above weight. Thereby, each receiving stand is more firmly fixed to the water bottom.
