Description

Technical Field [0001] The present invention relates to a wind power generator using a vehicle wind,

The present invention relates to a wind power generator using vehicle wind. More specifically, it is possible to improve a single material and a fixed rotary blade from strong winds, thereby making it possible to operate the blades safely from a natural environment change. In addition, it is possible to install the blade at a high speed, The present invention relates to a wind turbine generator for generating electric power in combination with a wind turbine generator to supply electric power independently to road facilities such as a traffic safety information system such as CCTV.

Generally, a wind turbine generator is a device that can generate electricity using wind, which is a clean energy source, and means a device that converts kinetic energy of air into mechanical energy and obtains electricity therefrom. The principle of wind power generation is the conversion of the mechanical kinetic energy generated by the aerodynamic wing-shaped rotor to the electric energy through the generator.

The wind turbine is a cost-effective way to improve the price competitiveness of the power generation unit cost and minimize the installation area of the power generation system, the social environment such as alternative energy source for fossil energy depletion and the earth environment protection, The economic aspect of reducing dependence on imports can be obtained. In recent years, various electric production methods using new and renewable energy sources such as wave, wind, solar, geothermal, etc. have been supported and expanded by the governmental institutional policy in order to purchase electric power produced by private companies in KEPCO, .

For example, Korean Patent Application No. 2011-0135158 discloses folding wind turbine blade technology. In this conventional technique, when the strong wind blows, the fixing portion 11 is installed so that the blade can be folded, and the spring 30 pushes the support plate 20 so that the angle at which the blade is folded is automatically adjusted according to the intensity of wind, The pushing force of the spring 30 can be adjusted by the adjusting device 40 using the screw so that the speed can be set in the wind.

However, such a wind turbine can only accommodate wind power in one direction and is not suitable for a highway on which a vortex phenomenon occurs. When the blades are frequently folded due to strong winds, the elasticity of the spring 30 is lowered, 40), and the maintenance cost is increased due to the increase of the durability.

In addition, Korean Patent Application No. 2002-30140 (May 30, 2002) discloses a hollow semi-circular wind-driven rotary blade having a ventilation groove, and Korean Patent Application No. 2001-81017 discloses a vertical- An angle changing device for a rotary blade is disclosed. Such a wind power generator has a problem in that when a strong wind is blown, the wing is damaged or damaged by strong winds.

On the other hand, the CCTV installed in the existing highways has to be operated at the same time with the road construction work due to the burial of the optical cable and the power cable, so that the process efficiency is lowered and the investment cost of the pipeline for cable facilities is excessive.

Therefore, a solution to this problem is required.

<Configuration and Function>

Hereinafter, the configuration and functions of a wind power generator using vehicle wind according to an embodiment of the present invention will be described.

1 is a partial perspective view of a wind turbine generator using vehicle wind shown in FIG. 1, FIG. 2b is a sectional view of a wind turbine generator according to a second embodiment of the present invention; FIG. Fig. 6 is a partial perspective view of a wind power generator using vehicle wind according to an example.

1, 2A, and 2B, a wind turbine generator 1 using vehicle wind according to the present invention includes a strut 10, a generator 20, and a generator 20 A rotating body 30 having a space guide 41 and a blade 42, and a capacitor (not shown).

However, the components shown in Figs. 1, 2A, and 2B are not essential, and a vehicle wind-driven wind turbine 1 having more or fewer components can be implemented.

As shown in Figs. 1, 2A and 2B, the pillars 10 may be formed in a long bar shape, such as on a central separator, on the outside of a highway, or the like.

The generator 20 is installed at one end of the strut, and receives the power of the rotating body 40, which will be described later, through the rotary shaft 30 to drive the generator 20. The generator 20 functions to convert the rotational power of the rotating body 40 into electric energy.

The rotary shaft 30 is connected to the generator 20 to drive the generator 20. Specifically, the blades 42 are installed on both sides of the rotary shaft 30, and transmit the rotation power of the blades 42 to the generator 20.

The rotating body 40 is provided on both sides facing each other with the rotating shaft 30 as a center. The rotating body 40 is provided with an arc-shaped air guide 41 on the inner side and a blade 42 having a twisted screw shape at a predetermined angle.

The blade 42 has a semicylindrical shape having a predetermined length and has a screw shape which is warped at a predetermined angle from the upper end side to the lower end side. The twist angle is not particularly limited, but is preferably 100 to 270 degrees in consideration of wind force, wind speed, rotational force, and the like. This is to effectively respond to the wind direction and the wind speed to increase the power generation efficiency during the same time. The rotation speed of the blade 42 in accordance with the twist angle is 39 times when the rotation angle of the rotary blade is 40 degrees and 40 degrees when the rotation angle is 270 degrees. The change of the speed is similar to that of Fig.

The blade 42 has an air guide portion 41 having an arcuate cross section formed in the longitudinal direction. The width of the air guide portion 41 gradually decreases toward the end side in the longitudinal direction of the center portion, The widths at the both end sides of the center portion 40 become narrower than the width at the center portion. The airflow introduced into the width air guide portions 41 at the both end sides of the blade 42 is dispersed in the longitudinal direction to prevent the rotation torque from being lowered.

Specifically, in the wind turbine generator 1 according to the first embodiment of the present invention, the outer side 43 of the blade is made of a material having a solid blade 42 such as plastic, epoxy, glass fiber and carbon fiber, The inner side 44 of the blade is made of a cloth (man-made fiber) so as to easily form the cut portion 42a.

Here, a cut portion 42a of a "|" shape is formed on the blade inner side 44 formed of cloth. The cut-out portion 42a allows the cut-out portion 42a to be separated from the cut-out portion 42a when a wind of a predetermined speed or more is received, so that when the strong wind blows, the blade 42 is broken or warped .

In this case, the cutout portion 42a may be formed in a "W" shape and other shapes as in the second embodiment shown in Fig. 2B as well as a " ) Have the same function.

A capacitor (not shown) is connected to the generator 20 to store electricity generated from the generator 20. Such a battery (not shown) may be a wireless communication module installed to be able to perform a wireless communication function with CCTV, traffic information center or traffic control center that illuminates a traveling path of the vehicle or photographs the vicinity of the traveling path of the vehicle. And the like.

3A is a partial perspective view of a wind power generator using vehicle wind according to a third embodiment of the present invention, and FIG. 3B is a partial perspective view of a wind power generator using vehicle wind according to a fourth embodiment of the present invention.

Here, in FIGS. 3A and 3B, components having the same function are denoted by the same reference numerals to facilitate understanding of the wind turbine generator using the wind turbine.

In addition, differences will be mainly described in explaining the modified examples of Figs. 3A and 3B on the basis of the first embodiment, and description of the same configuration will be omitted or reduced.

3 (a) and 3 (b), a support 10, a generator 20, a rotary shaft 30 for driving the generator 20, a space having a space guide portion 41 and a blade 42 An entire body 40, and a capacitor (not shown).

Here, unlike the first and second embodiments of the present invention, the entire blade 42 is a cloth, and a plurality of cutouts 42a are formed on the inside thereof. The cut-out portion 42a may be formed in a "W" shape and other shapes as shown in Fig. 3B as well as a " , The wind is separated by the wind pressure so as to perform the same function as the above-described embodiment.

However, since the entire blade 42 is a cloth, a blade support (not shown) may be installed along the outer line of the blade 42. The blade support can prevent the blade 42 from being deformed due to wind. It is also possible to provide a plurality of lights on the outer side of the blade support to make the appearance of the blade stand more beautiful.

4 is a partial perspective view of a wind turbine generator using vehicle wind according to a fifth embodiment of the present invention.

As shown in Fig. 4, the blades 42 are formed with a plurality of holes 42b. The cover portion 45 is located at a peripheral portion of each hole 42b and covers the hole 42b and has a pivot portion 46 at one side thereof. Here, the material of the cover portion 45 is preferably made of the same material as the blade.

Further, the swivel portion 46 is tightly bonded so that the cover portion 45 is not separated from the blade even in strong winds. Accordingly, when receiving wind of a predetermined speed or less, the swinging portion 46 is not operated, and the cover portion 45 is brought into close contact with the hole 42b to close the hole.

However, when the wind pressure exceeds a predetermined speed and the wind pressure rises, the cover portion 45 is rotated by the turning portion 46, so that the hole 42b is opened to allow a part of the wind to pass therethrough, , Thereby preventing the blade 42 from being damaged by strong winds.

<Operation procedure>

Hereinafter, an operation process of the wind power generator according to the first embodiment of the present invention will be described with reference to the drawings.

Meanwhile, FIG. 6 is an operational state diagram of the wind power generator according to the first embodiment of the present invention when the wind speed exceeds a predetermined speed.

In this process, the air introduced into the air guide portion 41, that is, the wind, rotates the blades 42 and is discharged from the air guide portion 41. The width of the blades 42 in the radial direction from the center portion It is possible to prevent the air from flowing in the vertical direction. The prevention of the air flow in the vertical direction can increase the time for the air to rotate the blade 42 to stay in the blade, Specifically, the air introduced into the air guide portion 41 of the blade 42 provides a rotational force to the blade 42, and when the blade 42 rotates, the air is guided in the radial direction Since the blade 42 is formed to be narrow in the vertical direction of the blade 42, the force of the wind in the vertical direction is prevented from increasing.

Since the blade 42 has the cut-out portion 42a, it is possible to prevent the blade 42 from being damaged due to the strong wind. When a strong wind is blown, the wind power generator 1 is rotated at a high speed by the strong wind, and wind pressure acts on the front surface of the air guide portion 41 of the blade 42. The centrifugal force and the wind pressure due to the high-speed rotation act to separate the cut-off portion 42a. As a result, the cross-sectional area of the blades 42 to which the wind pressure acts is reduced by discharging the wind through the cut-away portion of the incised portion 42a, thereby reducing the rotational force and further preventing the blades 42 from being damaged by strong winds .

8 is a perspective view illustrating a state in which the wind power generator using the vehicle wind shown in FIG. 1 is installed on the center separator of the highway.

As shown in FIG. 6, the wind turbine generator 1 using the wind speed according to the present invention can be installed in a highway median separator. Here, when the wind power generators are large in size, they are installed at wide intervals, and when the wind power generators are small in size, a plurality of wind turbines are installed at a relatively narrow interval, so that power supply and demand can be facilitated.

Thus, it is possible to install the vehicle without requiring a separate installation space on the median separator of the road, so that it is possible to supply power to lights and other facilities such as roads, trunk roads, Can supply.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the present invention.
