Description

Device for production of electricity from wind energy driven in the air by balloon}

The present invention relates to a wind power generator driven in the air by a balloon.

Wind power generation is a relatively recent power generator designed to produce renewable energy, and has been in the spotlight as an alternative to replacing existing coal-fired power plants.

The wind generator consists of three parts: the wing, the transmission and the generator. The wing is a device that is rotated by the wind and converts wind energy into mechanical energy. The transmission rotates the generator by transmitting the rotational force generated from the wing to the transmission gear through the central rotation shaft and increasing it to the number of revolutions required by the generator. A generator is a device that converts mechanical energy generated by the wing into electrical energy.

Wind power generators are divided into a vertical axis windmill with a rotation axis installed perpendicular to the ground and a horizontal axis windmill with a rotation axis installed horizontally with respect to the ground according to the direction of the rotation axis of the wing. The horizontal axis windmill is simple to install because of its simple structure, but it is affected by the direction of the wind. The vertical axis windmill can be installed and used in a desert or plain because it is irrelevant to the wind direction, but the material is expensive and its efficiency is inferior to the horizontal axis windmill.

Such a wind generator has a form in which a vertical column is usually erected upright on the sea or on land, and a blade is installed on the top.

However, such wind power generators have limitations in terms of height, so they are not easy to take full advantage of the abundant wind of the air, and when installed on land, there is a problem that the neighboring living environment is deteriorated due to high noise, and when installed at sea, Closer handling of weather conditions is necessary.

To this end, a wind power generator supporting the air has been devised. In this regard, Korean Patent No. 1395910 discloses a balloon-type wind power generator.

The above invention is installed in the air by using the buoyancy to perform wind power generation, and a plurality of generators installed therein to rotate in different directions to prevent the yawing of the wind generator caused by the wind discharged from the propeller to provide a stable power generation An object of the present invention is to provide a balloon-type wind power generator. To this end, a buoyant body for providing a flotation force by storing a gas lighter than air in a closed space; A passage part which passes through the center of the support body and provides a movement path of the wind; And a plurality of power generating units installed in a line in the passage unit and having a rotor and a propeller integrated therein, wherein the plurality of power generating units rotate in opposite directions to the wind passing through the passage to perform power generation. Characterized in that. Therefore, the plurality of generators are rotated in different directions to prevent the yawing of the wind generator due to the wind discharged from the propeller has the advantage that can provide a stable power generation.

However, the scale is increased by having a plurality of propellers and a plurality of power generation units corresponding thereto, and in particular, there is a problem in that there is no method for securing stability of propeller driving against various wind directions.

1 is a schematic view showing a wind power generator according to an embodiment of the present invention.

As shown in FIG. 1, the wind power generator 100 of the present invention includes a balloon 101 provided for aerial injury; A support portion 105 connected by the balloon 101 and a plurality of connecting members 103; A buffer unit coupled to a lower portion of the support unit 105; A shaft (109) having a first end portion (133) rotatably coupled to the support portion (105) and extending downward through the buffer portion while being perpendicular to the support portion (105); A blade 111 coupled to the shaft 109 at the lower portion of the buffer part and rotating according to wind; The generator 119 is connected to the shaft 109 and generates electricity according to the rotation of the shaft 109.

2 is a schematic view showing a wind power generator according to another preferred embodiment of the present invention, Figure 3 is a vertical sectional view showing a wind power generator according to another preferred embodiment of the present invention, Figure 4 is a buffer of Figure 3 It is sectional drawing which expanded and showed.

As shown, in the present invention, the wind power generator 100 is floated in the air by using the balloon 101. When the balloon 101 is used, the height of the air is adjustable, and the existing wind power generator 100 is used. Compared to), since the wind power generation is possible at a higher position, the opportunity to obtain stronger wind power is higher than that of the conventional wind power generator 100, and thus, the possibility of obtaining a larger amount of electricity may be increased. However, when using the balloon 101, compared to the general wind power generator 100, since there is no device to fix it in the air floating state, there is a disadvantage that is affected by the wind or wind direction in the air. do. Therefore, the stability of the rotation of the blade 111 is lowered, the power generation function is lowered, and ultimately, there is a high risk of damage to the wind power generator 100. Therefore, control of this is necessary.

The balloon 101 is connected by the lower plate 127 and the plurality of connecting members 103, and the plate 127 supports the shaft 109, the blade 111, and the like. 105). The support portion 105 and the balloon 101 are preferably connected using a connecting rope as the connecting member 103, but the connecting member 103 is not limited thereto, and various connecting members 103 may be used. . The material of the connecting body 103 is also not limited to a specific material, and the balloon 101 may support the lower wind power generator 100 well, and at the same time, a flexible material that does not break even in high wind and various wind directions is sufficient. Do.

The size or type of the balloon 101 is not limited, and the method for levitation of the balloon 101 is not limited, so a detailed description thereof will be omitted.

The support portion 105 is connected to the shaft 109 that rotates together with the blade 111, the shaft 109 is formed to rotate at the same time even if configured integrally with the blade 111 or separately configured main gear (to be described later) 115 and its driven gear 117 can be rotated to generate power by the generator 119.

The blade 111 is not limited in the installation direction, for example, the blade 111 may be installed in the form shown, or may be installed to achieve a direction of 90 degrees with the form shown. However, in the latter case, it is necessary to switch the direction of rotation through the shaft 109 and the bevel gear.

The shape of the blade 111 may be designed to implement a high rotational force to best reflect the wind power, and the design and implementation of such a blade 111 is beyond the scope of the present invention will not be described in detail. . In the present invention, the rotation surface of the blade 111 is perpendicular to the shaft 109.

The support part 105 may have a flat shape having a predetermined thickness, and may have a circular or polygonal shape based on a plan view. The reason for having a certain thickness is because the upper end 133, which is the first end 133 of the shaft 109, should be embedded in the support part 105 in a rotatable state.

As an example, the support portion 105 is formed inside the recess 131 is formed to accommodate the upper end 133 of the shaft 109, the upper end 133 of the shaft 109 also forming a shape is It is embedded in the support portion 105, the spherical shape between the inner surface of the buried groove 131 and the upper end 133 of the shaft 109 to rotate the shaft 109 independently of the support portion 105 The bearing 129 may be further included. That is, the shaft 109 may have an upper end portion 133 supported by a buried groove 131 in the support portion 105, and may flow like a pendulum about the upper end portion 133. . At this time, the bearing 129 acts so that the upper end 133 of the shaft 109 smoothly flows in the buried groove 131.

The reason for doing so is to prevent the shaft 109 from being suddenly damaged by the wind by being coupled to the support portion 105 so as to be mutually flowable. That is, when the shaft 109 is coupled to the support 105 in a non-flowable manner, there is a possibility that a strong stress acts on the connecting portion of the shaft 109 and the support 105 to be broken, and this situation is prevented in advance. To do this.

Basically, the shaft 109 extends vertically downwards, for example configured to be orthogonal to the upper or lower surface of the support 105, which gravity acts on the construction of a gear or the like coupled to the lower portion of the shaft 109. Because. Since the shaft 109 is designed based on the extension direction as described above, other components such as the blade 111 may maintain the vertical downward extension direction as much as possible.

A buffer part is formed below the support part 105, and this buffer part serves to buffer some deviation from the vertical direction of the shaft 109. Of course, it does not maintain the complete vertical downward extension state, but at least serves to buffer the shaft 109 and the blade 111 to some extent rocking by the wind.

The shock absorbing portion is coupled to the lower surface of the support portion 105 and moves together with the support portion 105, and includes a plate 127, an elastic means 123, a flow means 125, and the like therein, and these components include a housing 107. Built in). The main body coupled to the lower surface of the support portion 105 is the housing 107, the elastic means 123 is coupled to the inner surface of the housing 107.

The shaft 109 is formed through the buffer part, and is coupled to or integrally formed with the plate 127 in the buffer part. That is, the plate 127 in the buffer portion rotates together with the shaft 109 when the shaft 109 rotates according to the rotation of the blade 111.

The shaft 109 has a through hole formed in a central portion of the buffer part, and the shaft 109 passes through the through hole. The through hole and the shaft 109 are spaced apart from each other to form a certain gap. The shaft 109 ) May flow from side to side based on the cross-sectional view as the distance from the through-hole corresponding to the wind and wind direction. Although described as being flowed from side to side on the basis of the cross-sectional view, it can actually flow in all directions. This is because the upper end portion 133 of the shaft 109 may be spherical so as to rotate through the bearing 129 in the buried groove 131 of the support portion 105.

The shaft 109 may be connected to the generator 119 to directly produce electricity. At this time, the transmission gear is connected to the shaft 109, the transmission gear serves to increase the rotational speed of the shaft 109 to enable power generation. Since the configuration thereof is a conventional configuration, descriptions including specific shapes will be omitted.

A main gear 115 configured to rotate together with the rotation of the shaft 109 may be coupled to the lower end of the second end of the shaft 109. In addition, the main gear 115 may be connected to the driven gear 117 is coupled to the generator 119 which is a power generator, or the generator 119 may be directly connected to the main gear 115.

An electric wire 121 may be connected to the ground storage device from the generator 119. In addition, the main gear 115, the driven gear 117 and the generator 119 is accommodated in the housing 113, the rotating shaft of the main gear 115 is a shaft 109, the driven gear 117 The rotating shaft is rotatably fixed to the inner surface of the housing 113.

The structure of the main gear 115 and the driven gear 117 and the generator 119 coupled to the main gear 115 or the generator 119 coupled to the driven gear 117 is applied using a conventional form, so Detailed description will be omitted.

A rope may be connected to the enclosure 113, and the rope may be fixed to the ground fixing means. As a result, the wind power generator 100 may be returned to the ground as needed.

Next, the buffer unit will be described in detail. 5 is a cross-sectional view showing the operating state of the buffer unit according to an embodiment of the present invention.

As shown, the shock absorbing portion is coupled orthogonal to the shaft 109 and rotates with the shaft 109; A housing 107 coupled to a lower portion of the support part 105 and surrounding the plate 127 and a part of the shaft 109 while being spaced in all directions with the plate 127; A plurality of elastic means 123 fixed to the inner wall of the housing 107 at intervals; And flow means 125 coupled to the elastic means 123 and fluidly coupled to the surface of the plate 127.

The plate 127 flows together when the shaft 109 flows by wind, because the plate 127 and the shaft 109 are combined or integral. Therefore, when the elastic control of the plate 127 can reduce the degree of this flow, ultimately it is possible to implement the stability of the power production. The elastic control of the plate 127 is an elastic means 123, the elastic means 123 includes a flow means 125, the flow means 125 flows while interviewing on the surface of the plate 127 It is in a possible state.

The elastic means 123 and the flow means 125 are formed on at least one surface of the plate 127 facing the support portion 105, and in this case, excessive flow of the shaft 109 may be controlled. However, if necessary, the elastic means 123 and the flow means 125 may be formed on the opposite surface of the surface.

As the elastic means 123 is inclined, the elastic means 123 at a position spaced apart from the shaft 109 is compressed, and at this time, the compressed elastic means 123 is provided with a plate 127. The restoring force to reinstate acts, and thus, the plate 127 can be returned to its original position so that the shaft 109 can be directed toward gravity as much as possible. This is to ensure the predictability of the power production by maintaining the initial state of the wind power generator 100 to the maximum, as described above.

The elastic means 123 will typically be a spring, but may also be used for automobile engine mounting (commonly referred to as "mi"), the engine mounting is designed to cushion the vibration and shaking of the vehicle body when driving the engine of the vehicle Means a rubber ball, rubber ball also has some degree of elasticity can be seen to be included in the elastic means (not shown).

It should be noted that the above embodiment is for the purpose of illustration and not for the purpose of limitation. In addition, those skilled in the art will understand that various embodiments are possible within the scope of the technical idea of the present invention.
