Description

[0001] The present invention relates to a drag type wind power generator,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drag-like wind power generation device, and more particularly, to a drag-like wind power generation device capable of effectively generating electricity through rotation of a rotating body by a drag force.

Conventional fossil energy resources have become increasingly depleted, and since the pollution of the global environment has been a concern, a great deal of effort has been devoted to the development of clean alternative energy devices that do not pollute the environment and pollute the environment.

These clean alternative energy sources include solar energy, wind energy, current energy, tidal energy, geo-thermal energy, bio-thermal energy, .

On the other hand, a wind power generator is used as means for generating electricity using the wind energy.

1, the wind turbine generator includes a pillar 10 installed at a high elevation, a blade 30 installed on a front surface of a cover 20 coupled to an upper end of the pillar 10, A gear box 40 installed inside the cover 20 to increase the rotational speed of the vanes 30 and connected to the gear box 40, And a generator 50 for generating electric power.

In the wind turbine generator having such a configuration, power is generated through the generator 50 by the power that is rotated by the vane 30.

However, the above-described conventional wind power generator has the following problems.

First, the conventional wind turbine generator has a problem in that the power generation efficiency is lower than that of the whole facility, and the power generation efficiency is low.

The conventional wind power generation apparatus is difficult to maximize the power of the vane 30 because the direction of the wind blowing from the front of the vane 30 and the direction of rotation of the vane 30 are perpendicular to each other .

In other words, the conventional wind turbine blade 30 is rotated by lifting force, and it is difficult to maximize the rotational force by the wind turbine.

Second, as described above, the efficiency of the power generation from the wind power generation apparatus is inferior. Therefore, in order to increase the power generation amount, the manufacturing cost and the installation cost are increased due to the increase in the size of the entire apparatus including the wing 30 of the wind power generation apparatus Thereby making it difficult to increase the economic efficiency.

Particularly, since the size of the entire plant becomes large as described above, it can not be applied to a small-sized power generation facility, and therefore there is a problem that the demand for the plant is limited.

Third, it is difficult to generate electricity in a very strong wind such as frequent changes of wind direction or wind blast, and maintenance parts are difficult because main parts such as wings (30) are installed at a high place from the ground. There were problems with weak drawbacks.

Fourthly, since the wing 30 is exposed to the outside, foreign matter or the like may hit the wing 30 and the wing 30 may be damaged, and there is a high risk of human accidents due to a human collision.

Korea Registration No. 10-1434656

SUMMARY OF THE INVENTION The present invention has been conceived to solve the problems described above, and it is an object of the present invention to provide a wind turbine that guides wind direction in a rotating direction of a rotating blade and generates power through rotation of a blade by a drag force, And to provide a drag-like wind power generation device capable of realizing a drag type wind power generation device.

In order to achieve the above object, according to the present invention, there is provided a rotary machine comprising: a rotating body including a rotating shaft; a plurality of rotating bodies fixed to the rotating body along the rotating direction of the rotating body around the rotating shaft; A guide path formed on one side of the rotating body to form a duct for discharging wind toward the drag blade and a guide wing for varying the direction of the wind so that the introduced wind is opposed to the drag force surface of the drag blade, And a power generating unit installed on the rotary shaft and generating electricity using rotation force of the rotary shaft, wherein each of the drag blades is roundly formed in one direction toward the direction opposite to the rotation of the rotary body, And the guide wing is formed to be rounded in a direction opposite to the direction in which the drag blade is rotated in the counterclockwise direction, One side of the rotor space partitioned by the drag blades is opened toward the discharge port of the body, and a plurality of rotor spaces partitioned by the drag blade And the other side is closed by the shielding plate.

In this case, the stray-passage pipe corresponds to the diameter of the rotating body, and includes a body forming a wind channel between an inlet through which the wind flows and a discharge hole through which wind is discharged toward the rotating body, The guide wing is formed along an inclined surface of the center body, and the guide wing is formed in a shape corresponding to each space formed between the drag wings, As shown in Fig.

The drag-like wind power generator according to the present invention has the following effects.

First, by providing a peristaltic tube that changes the direction of wind so that the rotational direction of the rotating body and the traveling direction of the wind become the same, the rotational power of the rotating body is maximized and the power generation amount can be increased.

In other words, since the drag force of the rotating body is rotated by the drag with the wind, the rotational force of the drag wing can be maximized, thereby maximizing the power generation amount.

Secondly, since the amount of power generation can be maximized as described above, it is possible to reduce the size of the wind power generator equipment.

That is, since the equipment of the wind turbine generator can be reduced in size, it can be applied not only to industrial facilities, but also to domestic and small-scale facilities, thereby improving economic efficiency and diversifying demand.

Third, even if the direction of the wind changes, the wind is always guided by the drag wings by the peristaltic tube, thereby improving the rotation efficiency of the drag wing.

Fourth, as the rotation efficiency of the drag blade is increased, there is no need to place the drag blade and the part at a high place from above the ground, so that the efficiency of the maintenance work for the wind power generator can be improved.

Fifth, since the drag wing is not exposed to the outside, it is possible to prevent the damage of the drag wing, and it is possible to prevent a human accident caused by colliding with the drag wing.

It is to be understood that the words or words used in the present specification and claims are not to be construed in a conventional or dictionary sense and that the inventor can properly define the concept of a term in order to describe its invention in the best possible way And should be construed in light of the meanings and concepts consistent with the technical idea of the present invention.

Hereinafter, a drag-like wind power generator according to a preferred embodiment of the present invention will be described with reference to FIGS. 2 to 6 attached hereto.

The drag type wind power generation device has a technical feature in rotating the rotating body for electric production and rotating the rotating body by using the drag force of wind.

That is, the direction of the wind blowing in the straight forward direction is changed in the rotating direction of the rotating body so that the drag force acts on the blades of the rotating body, thereby maximizing the rotating force of the rotating body.

2 to 4, the drag-like wind power generation apparatus includes a rotating body 100, a drag blade 200, a stub wind tube 300, and a power generation unit 400.

The rotating body 100 rotates by the force of the wind introduced through the peristaltic tube 300 and generates a rotating force.

The rotating body 100 includes a rotating shaft 110 that can transmit a rotating force to the power generating unit 400, and is preferably formed in a circular shape to enhance the efficiency of rotation.

The rotating body 100 includes an axial coupling portion 120 and a shielding plate 130.

The shaft coupling portion 120 is configured to couple the rotation shaft 110 and constitute the center of the rotation body 100.

The shaft coupling portion 120 is formed in a cylindrical shape and defines a shaft hole 121 to which the rotation shaft 110 is fixed.

The shield plate 130 constitutes the rotating body 100 together with the shaft coupling unit 120 and is coupled to the shaft coupling unit 120

The shielding plate 130 prevents wind leaking toward the drag blade 200 through the peristaltic tube 300 and is formed in a disk shape.

The shielding plate 130 forms a width corresponding to the rounded length of the drag blade 200, as shown in FIGS.

That is, the diameter of the shielding plate 130 is such that the other end of the dragging blade 200 can be positioned at the edge of the shielding plate 130.

One side of the rotating body 100 is opened by the construction of the shielding plate 130 and the other side of the rotating body 100 is closed by the shielding plate 130.

Next, the drag blade 200 rotates the rotating body 100 by the force of the wind discharged through the peristaltic tube 300, and a plurality of the drag blade 200 are installed along the circumferential surface of the shaft coupling portion 120 .

The drag blade 200 is formed to be rounded in a direction opposite to the rotating direction of the rotating body 100.

3, one end of the drag blade 200 is fixed to the circumferential surface of the shaft coupling part 120 and is fixed corresponding to the thickness of the shaft coupling part 120, And the other end portion is formed to be bent from one end of the drag blade 200 toward the opposite side in the rotating direction of the rotating body 100 and fixed to the longest end of the shield plate 130. [

Accordingly, the drag blade 200 forms a drag surface 210 that can be opposed to the wind.

In addition, due to the configuration of the drag blade 200, a plurality of spaces S1 defined by the drag blade 200 are formed in the rotating body 100.

Next, the peristyle tube 300 serves as a guide for discharging wind blowing to the outside to the rotating body 100, and is formed into a cylindrical shape having a diameter corresponding to the diameter of the rotating body 100.

The peristyle tube 300 is located on one side of the rotating body 100 where the drag blade 200 is installed and a passage 300a through which wind flows is formed inside the peristyle tube 300.

As shown in FIGS. 2 and 3, the peristaltic tube 300 includes a body 310, a central body 320, and a guide vane 330.

The body 310 constitutes an appearance of the peristoon tube 300, and is formed as a hollow cylinder.

One side of the body 310 forms an inlet 310a through which the wind flows and the other side of the body 310 forms a discharge port 310b through which the wind is discharged toward the rotating body 100.

The body 310 is formed with a pedestal 311 capable of supporting the body 310.

The central body 320 serves to guide the wind introduced through the inlet port 310a to the rotating body 100 and is disposed in a channel of the body 310. [

The central body 320 is formed so that its diameter gradually increases from the inlet 310a to the outlet 310b.

That is, the central body 320 is preferably formed in a conical shape.

This is because the wind introduced through the inlet port 310a spreads along the central body 320 to increase the rotation efficiency of the rotating body 100 so that the drag wing 200, which is the outermost one of the drag wings 200 of the rotating body 100, (200).

By concentrating the wind at the other end of the drag blade 200, i.e., at the outermost side of the drag blade 200, the efficiency of the force for rotating the drag blade 200 can be maximized.

The guide wing 330 guides the wind introduced through the inlet 310a to the drag surface 210 of the drag blade 200 and is installed between the center body 320 and the body 310. [

The guide wings 330 are formed in plural along the center body 320, and the number of the guide wings 330 corresponds to the drag wing 200.

With this configuration, the discharge port 310b of the body 310 is partitioned by the guide vane 330, and the divided space S2 is partitioned by the space defined by the drag blade 200 of the rotating body 100 (S1).

The guide wings 330 are formed to be rounded along the plane of the center body 120 and rounded in a direction opposite to the direction in which the drag blades 200 are rounded.

Since the guide wings 330 are formed to be rounded in the direction opposite to the direction in which the drag wings 200 are rounded, the wind is guided along the guide wings 330 to face the drag force surface 210 of the drag wings 200 .

In other words, the direction of the wind flowed through the peristaltic tube 300 is guided through the guide vanes 330 and discharged to the space S1 formed by the drag vanes 200 of the rotating body 100, The direction in which the wind travels is the same as the direction of rotation of the rotating body 100 and can be opposed to the drag surface 210 of the drag blade 200 as the drag surface 210 of the blade 200 is varied .

Next, the power generation unit 400 serves to produce electricity using the rotational force of the rotating body 100, and is installed on the rotating shaft 110.

The configuration of the power generator 400 is the same as that of a conventional power generator that generates electricity using rotational force, and a detailed description thereof will be omitted.

Hereinafter, the combination and operation of the drag-like wind power generator having the above-described configuration will be described.

The rotary shaft 110 is fixed to the rotary body 100 and the rotary shaft 110 is interlocked with the rotation of the rotary body 100.

The rotating shaft 110 is installed in the power generating unit 400 installed in front of the rotating body 100 as shown in FIG. 2 through the shaft hole 121 of the rotating body 100.

At this time, although not shown, the rotary shaft 110 is supported by rotation assist means such as a bearing provided on the shaft hole 121 of the rotary body 100.

On the other hand, the drag-like wind power generation device thus combined is installed outdoors.

Hereinafter, the operation in which the rotating body 100 is rotated by the wind will be described.

The wind is introduced into the duct 300a through the inlet 310 of the peristaltic tube 300 and the wind introduced into the duct 300a is guided along the curvature of the guide vane 330 rounded on the central body 320. [

At this time, since the guide vane 330 is rounded in one direction on the central body 320, the wind rotates like a vortex along the guide vane 330 and is discharged through a plurality of discharge ports 310b.

At this time, the wind direction guided by the guide vane 330 is changed toward the drag force surface 210 of the drag blade 200 installed in the rotating body 100.

Accordingly, the wind generates wind force toward the drag surface 210 of the drag blade 200, and the drag blade 200 of the rotate body 100 rotates the rotating body 100.

Particularly, in this process, the wind discharged through the discharge port 310b is discharged along the central body 320 whose diameter gradually increases toward the discharge port 310b, so that the wind is directed toward the drag surface 210 of the drag blade 200 However, the rotation force of the rotating body 100 can be maximized because it generates a pressure toward the outer-most-side-side drag surface 210 of the drag blade 200.

Then, as the rotating body 100 is rotated, the rotating shaft 110 fixed to the rotating body 100 is also rotated to produce electricity through the power generating unit 400.

Meanwhile, a wind collecting pipe 500 may be further installed in the peristaltic lamp 300 so that the wind can be efficiently collected in the channel 300a.

This is shown as another embodiment of the present invention and will be described with reference to FIGS. 7 and 8 attached hereto.

Prior to description, the same components as those of the preferred embodiment are denoted by the same reference numerals, and a detailed description thereof will be omitted.

As shown in FIGS. 7 and 8, a wind collecting pipe 500 is further installed at the inlet 300a of the peristaltic pipe 300.

The wind collecting pipe 500 is a structure for efficiently collecting outside wind into the pipeline 300a of the peristaltic canal 300 and has an enlarged diameter increasing gradually toward the outside from the inflow port 310a side of the peristaltic- .

Thus, the wind collecting pipe 500 is formed in the shape of an enlarged diameter gradually increasing toward the outer side of the peristyle tube 300, so that the wind can be efficiently collected into the duct 300a of the peristaltic tube 300.

The wind collecting pipe 500 is arranged such that a path of the wind gathering pipe 500 from the outside of the stray wind pipe 300 toward the inlet port 310a of the stray wind pipe 300 As it becomes smaller, it becomes a reducer.

Accordingly, since the intensity of the wind flowing into the peristyle can be increased through the wind collecting pipe 500, the rotational force of the rotating body 100 can be further doubled.

As described above, the drag-like wind power generation apparatus according to the present invention has a round drag drag blade 200 installed on a rotating body 100, and a direction of a wind toward a drag force surface 210 of the drag blade 200 And a diverting tube (300) for varying the diameter of the diverging tube (300).

That is, since the rotating body 100 is configured to be rotated by the drag force, the rotational force is maximized, thereby maximizing the electric production capacity.

As a result, the efficiency of electricity production can be enhanced, and the facilities of the wind power generation device can be downsized, thereby diversifying the customer's demand.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art.
