Abstract

(57) [Summary] (Modifications required) [Problem] Since conventional large-scale wind power generators are open-type tower-type propellers, (a) Nacelle blades, etc. are at high places, making installation and maintenance difficult. . (B) If the tower (tower) is raised, more wind energy can be received, but it is necessary to improve the drawbacks such as increasing the construction cost. SOLUTION: A wind power generator is provided with a direction control turntable installed in a building, and a plurality of rotors 3 are alternately built in a normal direction and a reverse direction in a cylinder composed of a wind guide port 1 on the windward side and a modified cylinder 2 on the leeward side. . Further, the hybrid wind power generator is provided with a solar power generation module 4 above a closed cowl 5 for protecting them.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a solar power generation facility that utilizes wind power generated in the upper part of a building.

[0002]

2. Description of the Related Art Conventionally, a wind turbine is mainly a large-sized machine using a tower-type propeller type, and power transmission to a demand area is performed by a power transmission line like other power generation facilities. In addition, small-sized machines are being developed in various ways, and the development of equipment combining solar power generation is urgently needed.

[0003]

Since the conventional large-scale wind power generator is an open type tower type propeller type, (a) the nacelle blade and the like are located at a high place, and installation and maintenance are not easy. (B) If you raise the tower, you can receive a lot of wind energy, but the construction cost will increase. (C) The wind energy received by the wind receiving surface is

As shown in FIG. 1, the net energy is about 30% due to the aerodynamic loss of 60%, the mechanical loss of the gearbox or the like of 4%, and the electromechanical loss of 6% of the generator or the like. (D) Transportation access to the site is not easy, and installation and land transportation costs are required. (E) There is a transmission loss from the site to the demand area. In addition, since the single-rotor is the mainstream for small and medium-sized wind power generators, (f) the total amount of power generation is smaller than that of large-sized wind turbines. (G) Generally, rotors and nacelles are exposed to wind and rain, so their service life is short. Had drawbacks such as.

[0004]

Wind power is generated in the upper part of a building which is comparable to that of conventional tower type power generation equipment. So on the roof of the building

[0005]

[Function] About 50 m above ground, about 1.
6 times higher wind speed can be obtained. Replacing this with energy gives 4.1 times. Further, even in the upper part of the building, wind that flows from the ground to the same wind energy is added to the upper part of the structure to convert energy higher than that in the past.

[0006]

Example (a)

As shown in FIG. 2, an air guide port 1 is provided on the windward side, and a modified cylinder 2 suppresses a decrease in the fluid velocity of the wind. (B) Inside the cylinder, the rotors 3 of alternating normal and reverse rotation are installed to compensate for aerodynamic loss. (C) By attaching a closed cowl 5 with a module 4 for photovoltaic power generation to the upper part, the main body such as the rotor and nacelle is protected and the amount of power generation is supplemented. (D) Heading control The heading can be easily controlled by the turntable.

[0007]

EFFECTS OF THE INVENTION By installing on the roof of a building or the like, installation and maintenance of equipment can be facilitated. In addition, the work risk is considerably reduced. Installation costs and equipment land transportation costs are reduced. Transmission cost and transmission loss are reduced. Aerodynamic losses are reduced. The useful life of the generator body can be extended. The direction can be controlled more easily than the direction control device for tower equipment.
