Abstract

<P>PROBLEM TO BE SOLVED: To provide a small-sized impeller wind power generation device capable of realizing highly efficient rotation of an impeller wind mill by collecting wind volume in a wide range. <P>SOLUTION: A fixed wind collecting surface 2 and a multi-function movable wind collecting board 4 collect wind volume in the wide range to the impeller 5 built in a frame for high rotational efficiency. The fixed wind collecting surface 2 covers the half portion of the impeller 5 to concentrate the wind power in a working portion. The multi-function movable wind collecting board 4 in which a top end gap 4-c is located is retained by an opening/closing link 7 connected with both side surface plates 1 of the frame, a link mechanism with an opening/closing control spring 7-c, and a retainer 8 to enlarge a wind port. The area of the wind port is automatically controlled corresponding to changes in the wind power, and the rotation of the impeller 5 is stabilized by an automatic wind volume adjustment to prevent chaotic generation. If the wind power exceeds its limit, a strong wind defense function, such as closing to the fixed wind collecting surface 2 is also carried out, and the impeller 5 is continuously rotated by the wind power entering from the top end gap 4-c. <P>COPYRIGHT: (C)2004,JPO&NCIPI

Description

TECHNICAL FIELD OF THE INVENTION
[0001]
The present invention seeks to make a technical embodiment in the field of wind power generators, in particular, to improve the efficiency of an impeller windmill that originally has small size characteristics.
[Prior art]
[0002]
Conventional wind power generators tend to be mainly propeller-type wind turbines and tend to be large-sized, resulting in an increase in cost. This implies that a large amount of wind power (volume) requires a large propeller, and the cost, land area, space, and installation location are limited.
[Problems to be solved by the invention]
[0003]
Therefore, by developing technology for improving the efficiency of small wind power generators that use impellers that are completely different in shape and are originally small, we propose to enable clean power generation at low cost regardless of the location. is there.
[Means for Solving the Problems]
[0004]
The technology of the present invention equips the impeller with a multifunctional wind collecting plate such as wind adjustment and countermeasures against strong winds, collects and integrates a wide range of surrounding air volume, measures wind intensity, and improves the rotating ability of the impeller. This is a small wind turbine and suggests the possibility of practical application from a different perspective from large propeller type wind turbine.
【Example】
[0005]
FIG. 1 will be described. The inside of a frame composed of a multifunctional movable air collecting plate (4) having opposed side plates (1), a fixed air collecting surface (2), and a wind direction plate (3) at the center, and having a tip gap (4-c). The generator (6) mounted on the side plate (1) is rotated to generate electricity, while the fixed wind collecting surface (2) has one half of the impeller (5). The multifunctional movable air collecting plate (4) is kept open until the limit wind speed by the opening / closing link (7), the opening / closing control spring (7-c) and the holder (8), and the fixed air collecting surface (4). Along with 2), a wide range of air volume is collected and integrated to achieve high efficiency of the rotation ability of the impeller (5). It also acts as a strong wind protection function that moves and closes against the fixed wind collecting surface (2), but with the wind power that enters through the tip gap (4-c), With high efficiency wind power generation apparatus equipped with a wind collecting plate, wherein the rotation continues roots wheel (5), a free wind direction on seating mount (9).
[0006]
The idea of the present invention is that the impeller (5) has a vertical / horizontal shaft type, multi-phase type structure (
FIG. 2).
While the impeller (5) of FIG. 1 is a horizontal axis type and a single phase type,
Fig. 2 is a vertical axis type multi-phase type. The high-efficiency wind power generator equipped with the multifunctional wind collecting plate of the present invention can be expanded to horizontal axis type, vertical axis type, single phase multi-phase type. It is an illustration of this.
[0007]
The multifunctional movable air collecting plate (4) floats with a change in wind force by a link mechanism including an opening / closing link (7) and an opening / closing control spring (7-c) which are connected to each other, and automatically controls the area of the air port to control the air volume. The automatic adjustment operation stabilizes the rotation of the impeller (5) to prevent turbulent power generation, and at the same time, if it exceeds the limit wind power, it rises and moves to close against the fixed wind collecting surface (2). However, a strong wind invades from the gap in the tip end gap (4-c), and the impeller (5) continues to rotate appropriately so that power can be generated.
【The invention's effect】
[0008]
The high-efficiency wind power generator equipped with the wind collecting plate of the present invention has a simple structure and a small size, so it is low cost, and has a high efficiency integrated as a multi-functional wind collecting device with all necessary functions integrated. It can be used practically. It is not limited to a place and can be laid easily.
