Description

Device for production of electricity driven by gear from wind energy comprising parallel multiful generator and driven in the air by balloon}

The present invention relates to a wind turbine generator of a gear type in which air is driven by a balloon and a plurality of generators form a parallel structure.

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

A wind generator consists of three parts: a wing, a transmission, and a 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 has a simple structure and is easy to install, but is affected by the wind direction. 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 the 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, these wind power generators have limitations in terms of height, so they are not easy to take full advantage of the abundant wind in the air, and when installed on land, there is a problem that the neighboring living environment is poor when installed on land, 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 generation units installed in a line in the passage unit and having a rotor and a propeller integrated therein, wherein the plurality of power generation units rotate in opposite directions to the wind passing through the passage unit 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, since one power generation unit corresponds to one propeller, power generation efficiency is not high. In addition, there is a problem that there is no method for securing the stability of the propeller drive for various wind direction.

As shown in FIG. 1, the wind power device of the present invention includes a balloon provided for aerial injury; A support part connected to a lower portion of the balloon; A shaft rotatably coupled to a first end of the first end and extending downward while being perpendicular to the support; A blade coupled to the shaft below the support and rotating in accordance with wind; A main gear coupled to the second end of the shaft and connected to the shaft and rotated as the shaft rotates according to the rotation of the blade; A driven gear interlocked with the main gear; And a generator connected to the driven gear and configured to generate electricity according to the rotation of the driven gear, wherein at least two driven gears are connected to the main gear.

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.

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). Support 105 and the balloon 101 is preferably connected using a connecting rope as the connecting body 103, but the connecting body 103 is not limited thereto, and various connecting bodies 103 may be used. . The material of the connector 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 which 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 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 best reflect the wind power to implement a high rotational force, 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 planar 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.

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 rotation axis 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.

Since 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, 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.

On the other hand, the shaft 109 is connected to the generator 119 to produce electricity directly, in which case the transmission gear is connected to the shaft 109, the transmission gear to increase the rotational speed of the shaft 109 to enable power generation Play a role. Since the configuration thereof is a conventional configuration, descriptions including specific shapes will be omitted.

The coupling relationship between the main gear 115 and the driven gear 117 to achieve the features of the present invention is a coupling relationship of the bevel gear as shown. In this case, the generator 119 coupled to the driven gear 117 and extending from the driven gear 117 is installed in the horizontal outward direction of the driven gear 117. The driven gear 117 may be coupled to a plurality of main gear 115, the higher the number of such coupling, the greater the strength of the wind to be injected, if there is enough wind power can increase the amount of power generation further There is an advantage.

In particular, as shown in FIG. 2, when a plurality of main gears are installed up and down using a coaxial shaft, and a plurality of driven gears are connected to the main gears, power generation can be further increased. However, this will be possible only if sufficient wind power is secured, which must be introduced in consideration of wind power in the air.

Since the bevel gear is larger in size of the main gear 115 and smaller in size of the driven gear 117, more driven gear 117 may be coupled to the main gear 115 so that annual wind power and power generation efficiency may be improved. In consideration of the size of the main gear 115 and the driven gear 117 and the number of the driven gear 117 coupled to the main gear 115 can be adjusted.

On the other hand, the wind turbine generator of the present invention may further include a shock absorbing portion, which is shown in Figure 4, Figure 5 shows an enlarged shock absorbing portion. Hereinafter, the purpose of introduction and detailed configuration of the buffer unit will be described. However, the purpose of introduction and detailed structure of the shock absorber are equally applied to FIGS. 10 and 14 described later.

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. 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 is required.

First, the support portion 105 is formed inside the recess 131 of the concrete shape for receiving the upper end 133 of the shaft 109, the upper end 133 of the shaft 109 also forming a concrete shape is A bearing of a spherical shape is embedded between the inner surface of the buried groove 131 and the upper end 133 of the shaft 109 so that the shaft 109 rotates independently of the support 105. 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 portion 105 in a non-flowable manner, there is a possibility that a strong stress acts on the connection portion between the shaft 109 and the support portion 105 and breaks. 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 configuration of the 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 the deviation from the vertical direction of the shaft 109 in an extension direction to some extent. Of course, it does not maintain the complete vertical downward extension state, but at least serves to buffer to some extent the shaft 109 and the blade 111 is severely shaken 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, and the shaft 109 ) May flow from side to side based on the cross-sectional view corresponding to the wind and wind direction by the separation distance with the through hole. 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 133 of the shaft 109 may be in a spherical shape and may rotate through the bearing 129 within the buried groove 131 of the support 105.

Next, the buffer unit will be described in detail. 6 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 the 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 elasticity control of the plate 127 can reduce the degree of this flow, and 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 a surface of the plate 127 facing at least 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, the rubber ball also has a certain degree of elasticity can be seen to be included in the elastic means (not shown).
