Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wind power generator for generating power by using wind power.

[0002]

In recent years, due to the necessity of environmental protection, a clean energy source has been required in place of a fossil energy source and the like, and wind power has attracted attention as such a clean energy source. Therefore, the development of a wind power generator excellent in safety and efficiency is required.

[0003] In this type of wind power generator, a wind turbine propeller is rotated by using the force of wind, and a power generator is turned by the rotational force to generate power. Therefore, in order to generate power efficiently, it is necessary to efficiently absorb and control wind power.
In the case of a strong wind such as a typhoon, it is necessary to suppress the rotation of the wind turbine propeller in order to prevent the wind turbine propeller from rotating more than necessary and causing the generator to fail or the wind turbine propeller from being damaged.

In view of the above, the present invention ensures that when the wind turbine propeller is pulled up to the upper part of the column, it is securely held so as not to fall unnecessarily, and the wind turbine propeller is lowered for safety in the event of a strong wind such as a typhoon, and the number of revolutions is easily reduced. It is an object to provide a wind power generation device that can be controlled.

[0005]

In order to solve the above-mentioned problems, in the present invention, a wind turbine propeller can be moved up and down along a column using elevating and supporting members such as wires and chains.
As described above, in the wind turbine generator according to the present invention, the wind turbine propeller has a shape capable of moving up and down. On the other hand, it is known that wind speed generally increases exponentially with respect to height from the ground.

[0006] Therefore, by lowering the wind turbine propeller downward in strong winds, it is possible to suppress the rotation speed of the wind turbine propeller. As described above, according to the present invention, it is possible to easily control the rotation speed of the wind turbine propeller during a strong wind such as a typhoon.

DESCRIPTION OF THE PREFERRED EMBODIMENTS One preferred embodiment of the present invention will be described below. FIG. 1 is an embodiment state diagram of the present invention, FIG. 2 is an enlarged front view of a main part of the present invention, FIG. 3 is a right side view thereof, FIG. 4 is a rear view thereof, and FIG. FIG.

As shown in FIG. 1, a wind power generator according to the present invention
The wind turbine propeller 1 moves up and down in the vertical direction.

FIGS. 2, 3 and 4 show the state near the upper end of the column 4 (the wind turbine propeller 1 is omitted).
The sliding pipe 5 slides on the column 4 in the vertical direction, while the rotating body 2 rotates on the sliding pipe 5. Bearings 9a and 9b are interposed between the sliding pipe 5 and the rotating body 2 to support the rotation of the rotating body 2.
Among the bearings 9b, the bearing mounted on the sliding pipe side is:
It has a tapered shape that expands downward, and has a shape that supports the rotating body 2 via a bearing mounted on the rotating body 2 side of the bearing 9b.

A fixing hook 7 provided near the upper end of the column 4 is used to fix the wind turbine propeller 1 near the upper portion of the column 4. The fixing method of the wind turbine propeller 1 is as follows.
The fixing hook 7 is fitted to a fixing hook catching hole (not shown) provided on the support column 4 and then fixed by inserting the fixing hook 7 into both of the above-mentioned hooking holes. At this time, the position of the tip of the fixed hook 7 and the position of the fixed hook catching hole 8 need to match. For this purpose, a V-shaped groove 10 is provided on the sliding pipe 5 in the present invention. FIG. 4 is an enlarged rear view of a main part of the present invention. The V-shaped groove 10 provided in the sliding pipe 5 includes a fixed hook engaging hole 8 provided in the sliding pipe 5, a fixed hook engaging hole (not shown) provided in the column 4, and both fixed hook engaging holes. It is provided to align the position of the hole and the fixing hook 7. That is, pillar 4 in the first place
Are provided at positions where the tips of the fixed hooks 7 are fitted. Therefore, the fixed hook hooking hole on the support post 4 and the fixed hook hooking hole 8 on the sliding pipe 5 only have to overlap each other. The positioning pins 11 are provided on the columns 4.
When the wind turbine propeller 1 is pulled up using the winch wire 13, the positioning pin 11 is fitted into the V-shaped groove 10. As described above, when the wind turbine propeller 1 is pulled up, the positioning pins 11 are fitted into the V-shaped grooves 10, so that the two fixed hook hooking holes overlap, and therefore, the fixed hooks 7 are fitted into the fixed hook hooking holes. It becomes possible.

A fixed hook release rope 14 is attached to the fixed hook 7. The fixed hook releasing rope 14 is passed through the lower portion of the column 4 via a pulley 3 b attached to the upper end of the column 4. If the fixed hook releasing rope 14 is pulled at the lower portion of the column 4, the fixed hook is released. 7 is disengaged from the fixed hook catching hole 8.

With the fixed hook 7 pulled out of the fixed hook engaging hole 8, the winch wire 13 is used to pull down the sliding pipe 5, the rotating body 2 and the windmill propeller 1 attached to the rotating body 2 downward. It is. That is, one end of the winch wire 13 is attached to the sliding pipe 5, and the other end of the winch wire 13 is connected to the lower portion of the column 4 through the pulley 3 a provided at the upper end of the column 4. And is attached to a winch 6 provided on the column 4 (see FIG. 5). Due to such a structure, the wind turbine propeller 1 can be pulled down by the winch 6 provided at the lower part of the column 4. At this time, the hoisting and unwinding with a winch can be performed by either a manual operation or an electric operation using a driving device.

According to the present invention, when the wind turbine propeller is pulled up to the upper part of the column, the wind turbine propeller can be securely held so as not to fall unnecessarily.
It is possible to lower the wind turbine propeller for safety and easily control the rotation speed.
