Description

Wind power generating device using asending flow of cavity formed by buildings}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wind power plant, and more particularly to wind power for effectively generating power from a building wind and a stack effect generated in a cavity between high-rise buildings. It relates to a power generation device.

Fossil fuels such as petroleum, coal, and natural gas, which are commonly used, are not exhausted due to the limitations of underground resources.The waste gases such as carbon monoxide and nitrogen oxides generated during combustion are not only used for air pollution but also for destroying the ozone layer and global warming. As the main culprit of destroying the natural environment by causing them to be destroyed, it is permanently available as an alternative and there is much interest in wind power generation, which is one of the most advantageous renewable energy technically and economically without polluting the environment.

Therefore, in the same vein, following the advanced countries such as Europe and the United States, the wind power generation project and the construction of wind farms have been actively promoted in Korea.

Most of the wind power generation currently installed in Korea has a large wind farm structure installed in Daegwallyeong or Jeju Island. However, due to the geographical conditions in Korea, the area where large-scale wind power generators can be installed is extremely limited and the installation cost is high. Therefore, it is seeking to implement a wind power generation system that can overcome local limitations and have a relatively low installation cost. Situation.

On the other hand, conventionally, since the wind generator is installed in a fixed state on the ground, there is a problem that the power generation efficiency is reduced when the wind speed and volume of the area is reduced.

In order to solve this problem, various forms of floating wind power generation systems have been proposed.

For example, Korean Patent Laid-Open Publication No. 10-2009-0030519 provides a power generation unit in a floating unit, so the floating unit is rotated according to the direction of the wind, so that the wind power using a mechanism capable of generating electricity in the generating unit irrespective of the wind direction. A power generation apparatus is disclosed.

Meanwhile, Japanese Patent Application Laid-Open No. 2011-174447 and Korean Laid-Open Patent Publication No. 10-2009-0115469 disclose a wind power generation system related to a tall building.

Specifically, Japanese Patent Application Laid-Open No. 2011-174447 forms an air inlet on the outer wall surface of the middle of the building and forms an air outlet communicating with the air inlet on the roof of the building, and connecting the air inlet and the air outlet to the air outlet side. Disclosed is a wind power generator that generates power using wind flowing through a duct.

In addition, the Republic of Korea Patent Publication No. 10-2009-0115469 In order to solve the problem caused by the installation space constraints that occur when installing the power tower on the roof of the building is configured a wind power generator on the outer wall of the upper floor of the building rather than the roof of the building. The technique is presented.

On the other hand, Korean Patent Laid-Open No. 10-2010-0030245 discloses an installation method of a wind power generation system using a building wind. That is, Korean Patent Laid-Open Publication No. 10-2010-0030245 discloses a method for installing a wind power generation system by selecting an installation position and analyzing efficiency of a wind power generator for using building wind.

However, the related arts, including the techniques of the above-mentioned patents, exhibit problems such as limited installation area, technical or economic constraints.

First, the floating air wind power generation technology is difficult to develop at a high height of more than 300m above the ground due to technical and economic problems.

In other words, although the development of wind power generation technology using high altitude mooring flotation to utilize the excellent wind sulfur resources above 300m is being attempted, significant technological innovation is required in view of economic efficiency considering that an astronomical budget should be put in comparison with the power generation efficiency. to be.

In addition, the conventional wind power generation system for applying to a high-rise building is also a technical and economical problem is not easy to actually apply or the situation is inapplicable.

That is, the conventional wind power generators applied to high-rise buildings are mainly designed to be applied to the inside or the roof of a building with a single building in mind, and the technique of Korean Patent Laid-Open Publication No. 10-2010-0030245 takes into account the building wind. There is a limit in terms of utilization of wind power only to consider attempts to use or wind flowing from side to side between buildings.

Republic of Korea Patent Publication No. 10-2009-0048831 (May 15, 2009) Republic of Korea Patent Publication No. 10-2010-0030245 (March 18, 2010) Republic of Korea Patent Publication No. 10-2011-0011954 (February 09, 2011) Republic of Korea Patent Publication No. 10-2009-0030519 (March 25, 2009) Japanese Laid-Open Patent 2011-174447 (September 08, 2011)

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings of FIGS. 1 to 6.

[Example 1]

First, a wind power generator according to a first embodiment of the present invention will be described with reference to FIGS. 1 to 4.

1 to 4, the present invention is a wind power generator using the upward flow of the building (C) cavity (C: Cavity), the support installed above the cavity (C) formed between the high-rise buildings Sieve 1; A power generation unit (2) installed to be supported by the support (1) to produce electric power by using an upflow in the cavity (C); And a support member 3 installed between the high-rise building B and the support 1 so that the support 1 is supported.

The cavity C is a space formed between the high-rise buildings B and refers to a space in which an upward flow due to the individual action or interaction of the building wind and the chimney effect can be caused.

In this embodiment, the floating body 1 is a mechanism in which a gas lighter than air is filled in the present embodiment, and a power generation unit 2 generating power by an upward flow inside the central through hole is provided.

The support member 3 includes a support cable 310 for supporting the support body 1, and a power line 320 for transmitting power generated by the generator 220 to a land charging unit (not shown). It is desirable to form a structure combined into one.

That is, the support member 3, at least one or more support cables 310 for supporting the support (1), and the power line 320 to send the power generated in the generator 220 to the charging unit (not shown) of the land ), And the outer cover 330 (outer cover) forming a protective layer while binding the support cable 310 and the power line 320 to one.

In this case, it is preferable that a separate protective coating is applied to the power line 320 in consideration of the electrical insulation of the support cable 310 and the durability of the power line 320 itself.

In addition, the support member 3 preferably supports the support body 1 at least at three points.

On the other hand, the power generation unit (2) provided inside the support body (1) is for generating electricity using wind power, the rotor 210 is rotated by the wind is provided, the rotor 210 is transmitted The generator 220 which generates electricity using the rotational force is connected. In particular, the rotor 220 (described later) that is directly rotated by the rising wind of the elements constituting the power generation unit 2 is preferably disposed in the center of the through hole of the support (1).

In addition, the rotor 210 is connected to the controller 230 for controlling the blade angle of the rotor, etc., the generator 220 supplies the generated electricity to a charging unit (not shown) installed in the building (B), etc. Power line 320 is connected to.

The operation of the present embodiment configured as described above is as follows.

When the flotation body 1 and the power generation unit 2 constituting the wind power generator according to the present invention are to be suspended in the upper part of the cavity part C of the high-rise building B, air is provided inside the flotation body 1. Lighter gases, such as helium gas, are charged.

When gas is filled into the internal space of the support body 1, the support body 1 floats in the air and is positioned above the cavity C between the buildings.

On the other hand, in the state where the wind power generator of the present invention is installed, building wind is generated between the high-rise buildings, or the air flow in the cavity (C) formed between the high-rise buildings due to the chimney effect by the air flow passing through the upper floor of the building (B). When is generated, the upward flow passes through the rotor 210 of the power generation unit 2 installed in the through hole in the center of the support body 1, in this process, electricity is generated from the power generation unit 2 by wind power You lose.

On the other hand, in order to minimize the fluctuation of the torque or power caused by the wind condition and to maintain the rated torque or power, the angle of the rotor blade is controlled by the control signal generated from the controller 230.

[Example 2]

Hereinafter, another embodiment of the wind power generator of the present invention will be described.

5 and 6, the wind turbine generator according to the present embodiment is basically the same as the wind turbine generator according to the first embodiment, and further includes the following components.

That is, the wind power generator according to the present embodiment, the altitude sensor (4) installed on the support (1) to detect the height of the support (1) and the support according to the sensing value of the altitude sensor (4) It is further provided with a gas injector 4 which is connected to inject gas into the sieve 1.

On the other hand, the gas injection connecting pipe 6 is connected between the gas injector 4 and the support body (1).

The operation of the present embodiment configured as described above is as follows.

Prior to the description, since the basic power generation process of the wind power generator according to the present embodiment is the same as in [Example 1], the description thereof will be omitted and only the operations related to the added components will be described.

Basically, since the support body 1 is filled with a gas lighter than air, the support member 3 is always tensioned by a force that tries to float above the support body 1.

However, when the temperature is rapidly lowered in winter, the volume of the gas injected into the support body 1 is reduced, and thus the buoyancy of the support body 1 is weakened, so that the altitude of the support body 1 is lowered. May occur.

In this case, when the tension applied to the support member 3 connected to the support body 1 is released, the support body 1 may not move back and forth, but may swing back and forth or from side to side. It works to prevent it from happening.

That is, when the altitude of the support body 1 is lowered, the altitude sensor 4 installed in the support body 1 detects this and sends a control signal, which is installed on the roof of the building B according to the control signal. The gas injector 4 is operated to inject gas into the support body 1, and when the support body 1 rises again to reach the original altitude according to gas injection, gas injection stops.

Therefore, according to the present embodiment, regardless of the temperature change of the upper portion of the building B, the floating body 1 is always positioned at a constant position without shaking back and forth and left and right, so that the upward flow through the cavity C is achieved. Wind power generation efficiency can be maintained stably.

As described above, the present invention according to each embodiment of the present invention when the building structure is made of a certain structure and the wind enters between the building and the building through which the wind enters the gap between the building through the bar, At this time, the wind power generator installed in the upper part of the building by using the rising wind can convert the wind energy into electrical energy.

In addition, the electrical energy thus produced can be used not only for the self-powered operation of the building, but also to generate additional power by generating more power, so that the present invention efficiently utilizes building wind (ie, urban wind). It provides a positive effect.

Meanwhile, the present invention is not limited to the above-described embodiments, and various changes and modifications can be made without departing from the scope of the technical spirit of the present invention. For example, in [Example 1], the support member 3 is disclosed as a structure in which the support cable 310 and the power line 320 are combined into one, but the support member is installed to support only the support body 1. In addition, the power line 320 may be configured to be disposed separately from the support body supporting member to send the power produced by the power generation unit 2 to the charging unit (not shown) of the building (B).

In particular, in the above [Example 1] and [Example 2], the support body 1 is illustrated as a mechanism in which a gas lighter than air is filled therein, but is not necessarily limited thereto. That is, the support body may be made of a rigid frame, not a mechanism filled with gas, and in this case, the support member connecting the building and the support body to support the support body is not a flexible cable. It is manufactured in the form of rod with rigidity.

Accordingly, the support body in the present invention is not limited to receiving the force that rises by itself by lighter gas than the air filled therein, and the structure that is supported by the rigid support that does not rise but stays in the upper part of the cavity of the building. It should be interpreted in a broad sense, including.

It is therefore to be understood that the above-described embodiments are to be considered in all respects only as illustrative and not restrictive.

Accordingly, the scope of the present invention is defined by the appended claims rather than the detailed description, and all changes or modifications derived from the meaning and scope of the claims and equivalents thereof are to be construed as being included within the scope of the present invention do.
