CONSTITUTION:The wind, blowing into a suction window 7, flows successively through ventiating air cylinders 9-11, aligned in a wind path 8, to blow in a cavity part 6, here each ventilating air cylinder is formed to conically trapezoidal shape, and air is compressed while flowing in each ventilating air cylinder 9-11, and gradually increased its power. Further air in the periphery is sucked as shown by an arrow head P, and the wind rushes to blow through the ventilating air cylinders 10, 11 by the total force, in this way, a wind mill 14 in the cavity part 6 can be rotated.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a power generation device that can efficiently utilize wind power.

In recent years, there has been much talk of an energy crisis, and wind energy, which is the most readily available energy source, is being reconsidered as a means of helping.

Since ancient times, humans have used natural wind as a power source for a variety of purposes, but its effective use in power generation devices has only recently reached its limit.

The main reasons for this are (1) natural wind is affected by weather conditions, and its wind force and direction are not constant; and (2) there are difficulties in using it, such as the relatively small concentration of energy per unit area. It will be done.

For example, conventional wind power generators use propeller-type wind turbines that receive direct wind.
In strong winds, the strong wind pressure and violent rotation of the wind turbine can lead to a dangerous situation, and the need to constantly align the wind turbine with the direction of the wind makes the device complicated.

In order to solve the above-mentioned drawbacks, this invention blows wind into a cylindrical tower from its outer circumferential surface to effectively utilize the wind power regardless of the direction of the wind, thereby increasing the generation rate. The purpose of the present invention is to provide a wind power generation device that can fully demonstrate its capabilities.

That is, this invention provides wind blowing windows in a honeycomb pattern on the outer peripheral surface of a cylindrical tower having a hollow part in the center,
A plurality of ventilation pipes are arranged in a row in each air passage leading from the blow window to the cavity, and at least the outer ventilation pipe is shaped into a truncated cone so that the outlet of the outer ventilation pipe opens at the center of the entrance of the inner ventilation pipe. A generator drive shaft is installed in the center of the cavity, and a windmill is attached to the drive shaft to receive wind from the ventilation cylinder.

Next, embodiments of the present invention shown in the drawings will be specifically described.

The tower body 1 is raised from the ground by several supports 2! It is assembled from a large number of tiered plates 3, which are supported in the air and stacked vertically at regular intervals, and partition plates 4 which are arranged radially between the upper and lower tiered plates 3.3.

The stepped plate 3 is formed into a disk shape with a circular hole 5 in the center. Therefore, the tower main body 1 is cylindrical and has a cavity 6 in the center. In addition, a honeycomb-shaped wind blowing window 7 is provided on the outer peripheral surface by the combination of the step plate 3 and the partition plate 4, and an air passage 8 is provided between the blowing window 7 and the cavity 6. The width becomes narrower towards the center.

Three ventilation cylinders 9, 10, 11 are arranged in each air passage 8 from the blow window 7 to the cavity 6. Each ventilation cylinder 9,1
0.11 is formed into a truncated cone shape and has an inlet 9a.

The diameter decreases sequentially from 10a and lla to exits 9b, 10b, and 11b. The outlets 9b and 10b of the outer ventilation cylinders 9 and 10 are opened at the center of the inlets 10a and 11a of the inner ventilation cylinders 10 and 11, and the outlet 11b of the innermost ventilation cylinder 11 is opened into the cavity 6. be. Note 1
Reference numeral 2 denotes support fittings for the ventilation cylinders 9, 10, and 11.

Also, in the center of the cavity 6 there is an emitter 1! A drive shaft 13 of a truss 18 is passed through, and a windmill 14 is fixedly attached to the drive shaft 13. The windmill 14 has several blades 15 that receive the wind pressure ejected from the outlet 11b of the ventilation cylinder 11, and are formed vertically long in the cavity 6, or are provided at intervals at each location that receives the wind pressure. Supports 16 and 17 for a drive shaft 13 are provided at both upper and lower ends of the tower body 1, and the lower end of the drive shaft 13 is connected to a generator 18 buried underground.

Since the wind power generation device according to the present invention has the above configuration, the tower main body 1 that is directly exposed to the wind always remains stationary, but since it has wind blowing windows 7 widely and uniformly on its outer circumferential surface, it can be used in any direction. Even if there is a strong wind, Uke can enter. The wind that has entered the blowing window 7 passes sequentially through the ventilation cylinders 9, 10° 11 arranged in a row in the air passage 8 and is blown into the cavity 6, but each ventilation cylinder 9, 10 and 11 has an inlet 9a and a loa. ,
lla yoshi also exit 9b.

Since 10b and Ilb have small truncated conical shapes, the air is compressed while passing through each ventilation cylinder 9, 10.11, and its momentum gradually increases. Moreover, the outside ventilation %) 9.10 outlet 9b, 10b is the inside ventilation cylinder 10, 11 inlet 10
a.

Since it opens at the center of the lid, the first ventilation pipe 9
When the wind blows vigorously from the air to the second ventilation cylinder 10, and from that ventilation cylinder 10 to the third ventilation cylinder 11, surrounding air is sucked in as shown by arrow P, and the total force is used to blow the air into the ventilation cylinder. 10, 11, blows very forcefully into the cavity 6, works to rotate the windmill 14 in the cavity 6, and then passes through the ventilation cylinders 11, 10.9 on the opposite side to the outside. The drive shaft 13 of the generator 18 rotates together with the windmill 14 to generate electricity.

Note that it is not necessary that all of the vent pipes 9, 10, and 11 be formed in a truncated conical shape, and one or two vent pipes 9,
Even if only 10 is formed in the above shape, the suction force acts on the air blowing into the vent pipe.

As explained above, most of the device in this invention is a static cylindrical tower, so it can be designed to ensure stability against wind pressure like a general building. Suitable for installation in In addition, we installed wind blowing windows in a honeycomb pattern all over the outer circumferential surface of the cylindrical tower.
The wind can blow from any direction, and even if you can, you can catch the wind through the windows in that direction. In addition, the wind that enters the blower window passes through multiple ventilation pipes, gradually increasing the wind pressure and acting as a powerful rotational action of the windmill, so wind power can be used efficiently and the generator can be operated even in light winds. It exhibits remarkable effects such as:
