Abstract

<P>PROBLEM TO BE SOLVED: To provide a wind speed increasing device for increasing the rotation of a wind mill by using wind passages corresponding to wind in any of north, south, east and west directions and having wind collecting performance to improve the flow-in efficiency of the wind and increase the speed thereof, and to provide a wind power generation device using the same. <P>SOLUTION: The wind speed increasing device has the wind passages whose right, left, top and bottom walls are gradually smaller as tending from wind passage inlets to wind passage outlets for giving the effects of collecting wind, increasing the speed of the wind and guiding the wind to flow into wind mill blades and accurately hit them. The wind passages are mounted in a plurality of holes formed at spaces in the side face of a cylindrical member for guiding the all directional wind to flow thereinto and a wind exhaust hole is installed at the upper part for escaping the wind. The wind speed increasing device in this construction and the vertical shaft type wind power generation device are used to form a generation plant. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

Detailed Description of the Invention

  This invention can respond to wind from any direction from east, west, south, and north, and by using a wind path with high wind collection, it is possible to increase the rotation speed of the windmill by improving and increasing the wind inflow efficiency. The present invention relates to a wind speed increasing device and a wind power generator using the same.

  Conventionally, as disclosed in Japanese Patent Application Laid-Open No. 2003-328922, there has been a wind power generator that generates electricity using a wind-intensifier that responds to a constant wind and accelerates the flow of the wind.

Problems to be solved by the invention

There were the following problems.
(B) It was only possible to respond to wind inflows in a specific direction, and wind utilization efficiency was low.
(B) In response to changes in the wind, the size of the device was increased if it was attempted to increase the efficiency of wind utilization.
The present invention has been made to solve these problems.

Means for solving the problem

  The wind passage where the top, bottom, left and right walls shrink from the wind passage entrance to the wind passage exit has the effect of collecting wind and speeding up, and a wind speed increasing device that guides inflow so that the wind hits the windmill blade accurately Provide. A wind speed increasing device is provided in which a wind passage for introducing and guiding wind in all directions is attached to a plurality of holes formed at intervals in the side surface of the cylindrical member, and a wind exhaust hole for allowing the wind to escape is installed in the upper part. The present invention is a power generator using the wind speed increasing device and the vertical axis wind power generator configured as described above.

Embodiments of the present invention will be described below.
(A) A plurality of appropriate values are provided by providing equal spacing to the side wall of the cylindrical member 1 so that the wind can be sent from any direction of east, west, south, and north to the cylindrical member 1 for smoothly applying the wind flow to the windmill blade 5a. A hole 1a having a large size is provided.
(B) In order to collect wind and strengthen the flow, the upper surface 2a and the lower surface 2b are reduced from the wind passage inlet toward the wind passage outlet, and the wind coming from the front is changed clockwise to make it easier to hit the windmill blade 5a. The right side surface 2c and the left side surface 2d are reduced from the wind passage entrance to the wind passage exit, and the right side surface 2c is further reduced more greatly than the left side surface 2d. Provide.
(C) In order to guide the wind collected and accelerated in the wind passage 2 to the wind turbine blades 5a, an opening at the exit of the wind passage of the wind passage 2 is provided around the hole 1a of the cylindrical member.
(D) In order to make it difficult for the wind collected and accelerated in the wind passage 2 to escape during the exit of the wind passage or during rotation of the windmill, the wind passage 2 and the cylindrical member 1 provided with the upper wall 3a and the lower wall 3b around the disk member 3 Provide to cover.
(E) In order to discharge the weakened wind in the cylindrical member 1, a plurality of appropriately sized wind exhaust holes 4 are provided near the center of the disk upper wall 3a.
(F) A vertical axis wind turbine 5 for power generation having a plurality of blades at equal intervals is provided at the center of the wind speed increasing device 6.
When the present invention is used in a structure as described above, the present invention is installed in a building. Electricity is generated by wind force, and the generated electric power is used in the building. It provides electricity to local communities in demand.

The invention's effect

It can be attached to the roof of a building or the ridge of a house. Furthermore, it can be installed on street lights on roads and bridges, and outdoor lights in parks and general household gardens.
Moreover, the amount of power generation can be increased by stacking a plurality in the vertical direction. Furthermore, a solar power generation device can be stacked.
Further, by covering the windmill body with the wind speed increasing device, it is safe for humans and animals not to touch the windmill blades by mistake.
Moreover, since it is a vertical axis type windmill, there is an advantage that the center of gravity is low and the impression of the landscape is not conspicuous. Therefore, even a wind farm can avoid a feeling of pressure on roads and neighboring private houses, and can be arranged.
It can also contribute to the local community as a business-use wind power generator for power supply.

It is a perspective view of the present invention. It is the figure which showed the flow of the wind of the horizontal cross section of this invention. It is an exploded perspective view of the present invention. It is the perspective view which installed this invention in the building. It is the figure which piled up this invention in the perpendicular direction, and was integrated with the solar power generation device.
