JP2004100496A - Natural-energy power generator - Google Patents

Abstract

<P>PROBLEM TO BE SOLVED: To provide a clean and regenerable natural-energy power generator which can quickly correspond to change in wind speed and direction, and is solid against strong wind such as a typhoon, friendly to humans, birds and beasts with less noise and vibration, can be installed in urban and offshore areas with its strong wind-collection power and payability. <P>SOLUTION: This natural-energy power generator generates a spiral air-flow by using heat obtained in a solar radiation-heat collection system and wind power passing through wind-introduction blades, and the generated air-flow is converted into rotation energy by a windmill. The rotation energy is converted to electric energy by a generator. Energy saving can be attained by cascade utilization of heat. By raising energy-flux density, this generator can be operated even by gentle wind in fine weather to raise an availability factor. Further, irregularity of natural energy can be relaxed, and the generator is promising in urban areas. <P>COPYRIGHT: (C)2004,JPO

Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to the generation of profitable natural energy.
[0002]
[Prior art]
A propeller-type wind power generator is a viscous fluid device that combines a turbine, a gearbox, and a generator, and has a simple structure. However, in order to extract energy from winds having a viscosity as low as 1/800 of that of water, a large turbine having a diameter about 30 times that of hydroelectric power generation is required.
[0003]
The disadvantages of propeller type wind power generators are mainly due to the high speed rotation of the turbine. Air has a high efficiency point with low viscosity and a small number of blades, such as three blades. If the noise problem is a concern, the environmental condition is to be about 300 m away from the residential area. There is a problem of birds and beasts protection and anxiety caused by danger images. A propeller-type wind generator with a knife rotating at high speed cannot be deployed in a Japanese environment. Japanese wind is relatively close to mountains, forests and buildings, so the surrounding wind conditions contain a lot of turbulent components. Under such conditions, there are many typhoons, which do not fit the situation of Japan, which is densely populated in a narrow country.
[0004]
The vertical axis wind generator has a low center of gravity because the generator is placed under the vertical axis wind turbine, and the sound of the propeller cutting off the wind does not occur. It is possible to cope with wind conditions that include a lot of turbulence components that occur because mountains, forests, buildings, etc. are relatively close. However, high speed rotation is not possible if only drag is used.
[0005]
Regarding the profitability of wind power generation, there are very few places in Japan with good wind conditions, and it can be said that it is difficult to generate profits as a business elsewhere.
[0006]
[Problems to be solved by the invention]
The problem to be solved is related to the irregularity and low density of renewable energy.
[0007]
[Means for Solving the Problems]
The main feature of the present invention is to utilize wind energy and heat energy in the same turbine.
[0008]
BEST MODE FOR CARRYING OUT THE INVENTION
The present invention is most efficient when there is a wind in the fine weather, but the solar heat can be stored in the heat collector, and a spiral airflow can be generated even when the weather is not clear. Since the air guide plate also serves as an inlet of the air collecting device, there is a greater air collecting effect. The air collecting device has a low pressure in the vicinity of the turbine, and an enlarged type to increase the flow velocity, and a brim is attached. At sea, the condensing and heat collecting system is of a centralized type (tower type). A large-scale and efficient power generation can be performed by using a tracking device equipped with a flat reflector called a heliostat to concentrate and heat the sea surface, and by using a stronger and more stable wind force than on land.
[0009]
【Example】
As shown in FIG. 1, the chimney of a thermal power plant, an incineration plant or a plant using thermal power can be directly used. By providing a spiral exhaust port inside the chimney, a stable output can be obtained.
[0010]
【The invention's effect】
As described above, the renewable energy generator of the present invention can be applied to increase the density of natural energy and enhance safety. It is also possible to make it portable and portable. It can be used in various industries such as agriculture, forestry and fisheries, industry, commerce, and service. It can also be used for hobby and sports such as education and outdoor. Natural energy can be regarded as a light image, a safe image, and an image friendly to humans and nature, and can contribute to a recycling-oriented society for the future.
