Problems solved by technology

[0007] However, if a brake mechanism is provided, not only the manufacturing cost of the wind power generator itself increases, but also the power generation efficiency is also reduced because the power generation is stopped when the wind turbine stops rotating.

Embodiment Construction

[0037] Next, the wind power generator according to this embodiment will be described. figure 1 is a front view showing the wind power generator 1, figure 2 yes figure 1 A side view of the wind power plant 1.

[0038] Such as figure 1 and figure 2 As shown, the wind power plant 1 has a cylindrical base 21 . A cylindrical cover 6 opening in the horizontal direction is provided on the upper end portion of the base 21 so as to be rotatable in the horizontal direction. The inside of the cover 6 is provided with: the windmill 5; the first support part 71, which supports the front end portion of the rotating shaft 51 of the windmill 5 in a rotatable state; the second supporting part 72, which supports the rear end of the rotating shaft 51 The ends are supported in a rotatable state. The generator 22 is provided behind the second support portion 72 , and the drive shaft 221 of the generator 22 is connected to the rotating shaft 51 of the windmill 5 .

[0039] In addition, a g...

Abstract

A wind power generating apparatus is provided with a plurality of board-like blades; a windmill having the blades, which are attached to the windmill by being bent with respect to a rotating shaft; and a power generator, which is connected to the shaft of the windmill and generates power when motive energy of the windmill is transmitted. The windmill has a pair of fixing tools fixed at a prescribed interval on the rotating shaft so as to fix the blades to the rotating shaft. On one of the pair of fixing tools, one end of the blade is fixed, and on the other fixing tool, the other end of the blade is fixed. A narrow section is formed at the center, and wide sections are formed to sandwich the narrow section.

Description

technical field [0001] The present invention relates to a wind power generator, and more particularly, to a wind power generator having a windmill using twisted blades. Background technique [0002] In a general windmill used in a wind power generator, a plurality of wings called blades are provided in a size capable of generating required electric power. In general windmills, since the size of the blades facing the wind direction is large, the installation place is limited. Here, if twisted blades are used, the wind force can be effectively acted as a rotational force. Therefore, compared with general windmills, the size of the blades facing the wind direction is smaller, but it can be expected to be equivalent to general windmills. Degree of rotational speed of the windmill. (For example, refer to Non-Patent Documents 1 and 2, and Patent Document 1).
