The present invention relates to a wind generator, and more particularly, to a wind generator that can prevent the breakage of the vertical blades due to strong winds.

In general, the wind generator refers to a device that converts the wind by the wind into kinetic energy through the rotor braid, which is a component of the wind generator, and then obtains electrical energy through the generator.

In other words, due to the use of fossil fuels such as coal and petroleum, a large amount of carbon dioxide accumulates in the atmosphere and forms a thick carbon dioxide layer, causing global warming. Also, due to the rapidly changing crude oil price, the need for alternative energy is known. R & D on development is expanding.

3 is a view showing a conventional wind power generator, the conventional wind power generator is a shaft shaft 100 which is provided perpendicular to the ground and the connecting table 101 is provided protruding around the outer side of the shaft shaft 100. It is composed of a generator 200 is provided between the wing 200 is rotated through the wind power and the shaft shaft 100 and the inner side of the connecting table 101 through the).

Therefore, when the wing is connected to the shaft shaft due to the wind power is generated by the generator.

However, in the conventional wind generator having the configuration described above, power can be generated by rotating the blades smoothly in normal times when the wind is weak, but a phenomenon in which the blades and the connecting rod are damaged by the strong wind due to the change of climate has occurred. . That is, the wing is connected to the upper portion of the shaft shaft through a connecting rod is open in one direction to contact the outside wind. Therefore, in the case of strong wind, the air in the air strongly contacted the upper part of the wing, causing the upper part of the wing to bend.

In addition, when the wind direction is irregular, the upper and lower portions of the wing as well as the phenomenon that the middle portion is bent.

That is, the damage of the wing due to the strong wind is mainly started at the upper part first, and the lower part and the middle part of the wing are damaged when the back wind occurs due to the backflow of the wind.

Therefore, as the wing is broken, the connecting rod connected to the wing that could not withstand the force of the wind is also bent, which has the problem that power generation using wind power is impossible.

Accordingly, the present invention has been made to solve the above problems, an object of the present invention to provide a wind generator that can prevent damage to the vertical blades due to strong winds.

Wind generator according to the present invention for achieving the above object is provided with a shaft shaft which is provided perpendicular to the ground, and at least one rotatable on the shaft shaft and a plurality of connecting rods at equal intervals around In the wind generator comprising a protruding rotating body, a plurality of vertical blades provided on the outside of the connecting rod rotated by the force of wind, and a generator connected to the shaft shaft, the upper, lower and middle of the vertical wings A through-hole is formed in the center so as to penetrate the shaft shaft, and a plurality of protruding plates for supporting the vertical wings are further provided with a fixed circumferential plate protruding at equal intervals.

Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

1 is a perspective view showing a preferred embodiment of the wind generator according to the present invention, Figure 2 is a cross-sectional view taken along line A-A of FIG.

As shown in the drawings, the wind generator according to the present invention, the shaft shaft 1 is provided perpendicular to the ground, and the shaft shaft 1 is provided with one or more rotatably provided at equal intervals around Rotors 2 are provided with a plurality of connecting rods 21 protruding, a plurality of vertical wings (3) provided on the outside of the connecting members 21 and rotated by the force of the wind, and the shaft shaft (1) In the wind generator comprising a generator (4) connected to the upper, lower and middle of the vertical blades (3), a through hole 51 is formed in the center so as to penetrate the shaft shaft (1) and the vertical blade ( 3) a plurality of protruding plates 52 for supporting them are further provided with a fixed circumferential plate 5 protruding at equal intervals.

In addition, the protrusion plate 52 has a through hole 521 formed at the center thereof, and a width of an outer side thereof is formed to be relatively wider than an inner width thereof, and both side ends 523 of each protrusion plate 52 have a streamlined shape. It is formed.

Therefore, when the wind pressure due to the strong wind increases, the vertical wing (3) due to the collision of the vertical wing (3) and the strong wind by dispersing the wind to the outside through the space portion 522 formed between the protrusion plate (52). ) Can be prevented from being broken.

That is, through the fixing circumferential plate (5) to protect a plurality of vertical wings (3) which are in direct contact with the outside wind, it is to increase the power generation efficiency by preventing the wind is dispersed.

In particular, the shaft shaft (1) is to be fixed to the ground, it can be fixed using a concrete or steel structure.

In addition, a plurality of spirals 11 are formed on an outer surface of the shaft shaft 1 so that the position can be fixed after adjusting the height of the vertical wings 3 provided on the outside of the shaft shaft 1. The nut 6 is fastened to the upper and lower portions of the rotor 2 and the generator 4 so as not to be lowered to fix the position.

In addition, since the bearing 22 is provided inside the rotating body 2, the rotating body 2 rotates smoothly with respect to the shaft axis 1.

On the other hand, the vertical wing 3 is formed in a semi-circular shape, but is not limited to this may be formed in a rectangular plate.

That is, the vertical wing 3 should be formed so that one side is open, and thus the vertical wing 3 is rotated in contact with the outside wind.

Hereinafter, the operation of the wind generator according to the preferred embodiment of the present invention configured as described above are as follows.

First, the wind is usually weak in the vertical wing (3) is smoothly rotated to generate power.

On the contrary, when the strong wind blows, the air in the air is strongly in contact with the vertical blades 3, wherein the fixed circumferential plate 5 firmly supports the upper, lower and middle portions of the vertical blades 3. 3) will be prevented from being bent by the force of the wind.

In other words, the wind collided with the vertical blades 3 can smoothly rotate the vertical blades 3 by letting out the space 522 and the through hole 521 of the protrusion plate 52.

In addition, by providing a fixed circumferential plate (5) in the upper, lower and middle of the vertical blade (3) in advance to prevent the phenomenon that the upper, lower and middle of the vertical wing (3) is damaged in advance. Will be.

In other words, even when the wind is generated due to the reverse flow of the wind through the fixing circumferential plate 5 by canceling the resistance of the wind is to prevent the breakage of the vertical wing (3).

And through the through holes 521 formed in the plurality of protrusions 52 to pass through the wind that is strongly in contact with the vertical blade (3) to prevent the bending of the connecting table 21 connecting the vertical blade (3) will be.

Therefore, the fixing circumference (5) is provided in the upper, lower and middle of the vertical wing (3) by the vertical wind (3) is damaged by the strong wind or wind blowing in an irregular direction, or the connecting table 21 due to the strong wind It is possible to prevent the bending.

As described above, the wind generator of the present invention has the effect of smoothly progressing power generation through the rotation of the vertical blades by preventing the vertical blades from being damaged due to strong winds.

While the present invention has been described with reference to the accompanying drawings, it will be apparent to those skilled in the art that many various obvious modifications are possible without departing from the scope of the invention from this description. Therefore, the scope of the invention should be construed by the claims described to include examples of many such variations.
