BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wind power generator for high-rise buildings that utilizes wind energy generated in high-rise buildings.

0002

2. Description of the Related Art Conventionally, wind power generation devices have generated wind power using a wind receiver such as a propeller or a windmill, and in particular, a propeller type device has been used to generate wind power by arranging a large number of propellers. Furthermore, in the past, propellers, windmills, and the like were generally installed in appropriate locations where wind energy existed, such as on the ground or on the roofs of buildings. However, in recent years, many high-rise buildings have been constructed in cities. It is known that in such a high-rise building 1, there is a large amount of wind energy, especially in the corner part 2, as shown in Fig. 7, and wind power generation using this wind energy is considered. Wind power generation using energy did not exist.

[Problem to be solved by the invention] When generating wind power using wind energy in such high-rise buildings,
In order to efficiently convert the wind energy generated at the corners of the outer wall of a building into rotational motion, a) the wind speed region generated at the corner of the outer wall has a velocity distribution similar to that of a jet flowing along the wall, so the wind speed There are problems in that it is extremely limited in large areas, and (b) the direction and speed of the external wind change significantly. For this reason, if a conventional power generation device is attached to the exterior wall of a building with its rotating part in the same shape as before, it is difficult to utilize the limited wind energy generated along the corners of the building. becomes difficult to use.

[0004] Therefore, the present invention was proposed with a focus on wind energy generated in high-rise buildings, and it is possible to efficiently generate power by grasping the state of wind energy generated at the outer wall corners of high-rise buildings. The purpose of the present invention is to provide a wind power generation device for high-rise buildings that can be used in high-rise buildings.

[0005]

[Means for Solving the Problems] The wind power generation device for high-rise buildings of the present invention includes a rotating wind receiving part that is protruded from the outer wall of a building and rotates by wind outside the building, and a rotating force of the rotating wind receiving part. It is characterized by being equipped with a driven generator. In such a wind power generation device, external wind that collides with the outer wall surface of a high-rise building and is accelerated on the outer wall portion is caught and rotated by the wind receiving rotating section, and this rotational movement drives the generator.

[0006] Therefore, electric output can be reliably obtained by utilizing the kinetic energy of the external wind of high-rise buildings in the city. In addition, although it is expected that the wind speed distribution in the direction outward from the exterior wall of the building will differ depending on the external wind conditions, when the wind direction and speed change, the wind speed distribution from the wind information sensor that detects the wind direction and wind speed will change. Based on the wind information, the control section controls the direction and position of the wind receiving rotating section and the wind receiving rotating section so that the direction and position of the wind receiving section are optimal. Therefore, the wind receiver and the wind receiver rotating part are controlled to the optimum direction and position so as to receive the maximum amount of external wind, so that it is possible to obtain efficient power generation output.

As shown in FIGS. 1 to 6, the wind power generation device 10 of this embodiment is installed at an outer wall corner 12 of a high-rise building 11 when viewed from the plane, and includes a generator 13, a support 14, and a wind receiving rotating section. 15, a wind information sensor 16, and a control section 17.

As shown in FIG. 2, the generators 13 are semi-embedded and fixed in the outer wall corners 12 of the building 17, and each generator 13 has a base end of a plate-shaped support 14 that is horizontally oscillating. movably supported. These supports 14 are disposed substantially horizontally, and a wind receiving rotating section 15 is provided between their tip ends. As shown in FIG. 2, the wind receiving rotating part 15 includes a rotating support body 21 made of two plate-like members and two wind receiving units 2.
It is composed of 2. The rotation support body 21 has its respective rotation center portions pivotally attached to the rotation main shaft 23, and this rotation main shaft 2
Both ends of the supporting shaft 24 are rotatably supported by bearings (not shown) within the distal end of the support 14.
A wind receiver 22 having a substantially half-column-shaped recess is pivotally attached to the shaft and can rotate together with the support shaft 24 . In addition, in Figure 2, 2

Further, in the tip of the support body 14, as shown schematically in FIG. A belt (cog belt) 28, which is provided in each support body 14 and transmits rotational power, is rotatably attached between 26 and the rotating shaft 27 of the generator 13. Also,
A wind receiving motor 29 provided in the rotary support 21 is connected to each support shaft 24, and the motor 29 causes the support shaft 24 to
The structure is such that each wind receiver 22 can be directed in any direction by rotating the wind receiver 22. For example, the wind receiver rotating portion 15 can be rotated in the opposite direction. Therefore, the rotation of the wind receiving rotating part 15 is transmitted to the belt 28 through the rotating main shaft 23 and the sprocket 26, and this belt 28 causes the generator 13 to rotate.
Electric power is generated by rotating the rotating shaft 27 of.

Each of the supports 14 is horizontally swingably supported, and as shown in FIGS. 3 and 4, the generator 13
In or near the support 14 is placed in a horizontal direction (for example, 18
A support motor 31 is provided to change the direction by displacing the support motor 31 (within a range of 0 degrees). Further, as shown in FIG. 5, a wind information sensor 16 is installed on the roof of the building 11 to detect wind information such as wind direction and wind speed.Based on the information from this sensor 16, the wind receiving motor 29 and A control section 17 for controlling the support motor 31 is provided. As shown in FIG. 6, this control section 17 includes a data processing section 32 that processes data from the wind information sensor 16.

[0011] Therefore, such a wind power generation device 10
By installing it on the outside wall of a building, it becomes possible to generate electricity by harnessing the powerful winds that blow through buildings in the city. Further, since the direction of the wind receiver 22 of the wind receiver rotating section 15 and the position of the wind receiver rotating section 15 itself can be changed by the control section 17 in response to changes in the wind direction and wind speed of the external wind, the wind receiver 22 The direction of the wind receiving rotating part 15 can be set to the optimum position, and the maximum output can always be obtained.
