Abstract

PURPOSE:To use solar rays for illumination and other purposes by converging the solar rays by using an optical system such as lens and by introducing them into a photoconductive body, through which the rays are transferred to any part where they are needed, on the other hand, to accumuate the solar energy in an induction substance by acting on a photochemical reaction in the induction substance, effectively utilizing the solar rays which are not introduced into the above-mentioned photoconductive body. CONSTITUTION:Lens 1 are controlled to automatically turn to the direction of the sun. The solar rays L converged by said lens 1 is introduced into a photoconductive body 2, to which focus point for said lens 1, a rays receptor end 2a is provided. The introduced solar rays L is transferred to any desired places passing through said photoconductive body 2 and are used as illumination and for the other purposes. On the other hand, the solar rays that are not introduced into the photoconductive body 2 at that time are irradiated into an induction substance 4 which flows through a transparent fluid passage 3, turning the induction substance into an isomer on high energy level by acting on a photochemical reaction in said induction substance to accumulate solar energy in it.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a solar energy collection and storage device;
In particular, sunlight is focused using an optical system such as a lens and introduced into the light guide, and transmitted through the light guide to any desired location for illumination or other uses, and the sunlight is introduced into the light guide. This system effectively utilizes the unused sunlight to cause a photochemical reaction in the inducer, thereby accumulating solar energy in the inducer.

The sunlight is focused using a lens etc. and introduced into the light guide.
The present applicant has already proposed various techniques for transmitting light to any desired location through the light guide for illumination or other uses.

In addition, recently, it has been reported that light is irradiated onto an inducing substance to cause a photochemical reaction in the inducing substance, thereby accumulating light energy in the inducing substance, and later extracting the energy accumulated in the inducing substance as thermal energy. There is growing interest in the technology (for example, see Japanese Patent Laid-Open No. 124657/1983).

The present invention was made in view of the above-mentioned circumstances, and
In particular, the two technologies described above are effectively combined to effectively utilize solar energy.

FIG. 1 is a side cross-sectional view of a main part for explaining one embodiment of the present invention, and FIG. 2 is a view taken from the direction of the line ■-■ in FIG.
In the figure, 1 is a lens for focusing sunlight, 2 is a light guide whose light-receiving end 2a is disposed near the focal point of the lens 1, and 3 is behind the light-receiving end 2a of the light guide 2. In the passage 3, an induction substance 4 that absorbs light energy, causes a photochemical reaction, and accumulates energy is flowed, for example, in the direction of the arrow. That is, in the present invention, the lens 1 is controlled to automatically face the sun by a well-known device (not shown), and the sunlight focused by the lens 1 is directed to the light receiving end at the focal position of the lens 1. 2a is introduced into a light guide 2 arranged therein and transmitted through the light guide 2 to any desired location for use in illumination or otherwise;
The sunlight that has not been introduced into the light guide 4 body 2 is irradiated onto the inducer 4 flowing in the transparent fluid passage 3, causing a photochemical reaction in the inducer and converting the inducer into an isomer with a high energy level. Changes in the body and stores energy. In this way, the induced substance that has accumulated energy flows in the direction of the arrow and is recovered, and then, for example, at night, when a catalyst is added, it returns to the original substance while generating heat, and the generated heat is converted into thermal energy. can be used.

Note that the induced substance that has returned to its original form in this manner is again stored with energy and reused as described above. As described above, according to the present invention, sunlight can not only be focused by a lens or the like and introduced into a light guide, and transmitted through the light guide to any desired location for illumination or other uses, By effectively utilizing the sunlight that was not used for illumination, the inducing material was made to have a high energy level, and the energy stored in the inducing material could later be used as thermal energy. Although energy can be used effectively,
The position of the light receiving end 2a of the light guide 2 is as shown in FIG.
When placed behind the focal point P of the ultraviolet rays, the viewing light is introduced into the light guide 2, and as soon as short wavelength light components such as ultraviolet rays are introduced into the light guide 2, the rear guidance light is introduced into the light guide 2. Since it reaches the substance, sunlight can be used more effectively (note that the inducing substance reacts to light components with wavelengths shorter than about 400 nm to cause a photochemical reaction).

FIG. 4 is a side sectional view of main parts showing another embodiment of the present invention,
In this embodiment, as shown in the figure, a black body 5 is provided on the inner wall of a transparent fluid passage 3 through which the induction substance 4 flows, and solar heat energy entering the fluid passage 3 is effectively applied to the induction substance 4. The temperature of the induction substance 4 is increased by the transmission, and when the induction substance is recovered, the thermal energy carried by the induction substance can be utilized.

FIG. 5 is a side cross-sectional view of a main part for explaining still another embodiment of the present invention. A solar cell 6 is provided, and the light that has passed through the induction material 4 is made to effectively act on the solar cell, so that the solar energy can also be used as electrical energy. Since short wavelength light components are absorbed and utilized by the inducing substance and do not reach the solar cells, these short wavelength light components are not stored in the solar cells as thermal energy. Accumulation does not cause a decrease in efficiency.

Note that FIG. 6 shows an example in which the black body 5 shown in FIG. 4 and the solar cell 6 shown in FIG. 5 are installed together; It is easy to understand that it is okay.

Although each embodiment of the present invention has been described above, the present invention is not limited to the above embodiments. For example, the intensity of sunlight is detected and the induction substance is In order to store energy in the inducer more efficiently by controlling the flow rate, or when using the present invention in the atmosphere where there is little ultraviolet rays, a sensitizer may be mixed into the inducer. It is also possible to use the sensitizer to convert light with a wavelength component of about 360 nm or less into light with a wavelength component of about 500 nm to more effectively cause a photochemical reaction in the inducer. .

FIG. 7 is a side sectional view of the main part showing another embodiment of the present invention, and FIG. 8 is a plan view of FIG. It is effective when targeting sunlight outside the atmosphere that contains a large amount of medium-long wavelength ultraviolet rays, etc., and the sensitizer required in the above example is not necessary. Sensitizers may be destroyed by strong ultraviolet light. The most characteristic effect of this embodiment is that strong ultraviolet rays and the like are absorbed and utilized by the inducing substance, thereby preventing these short wavelength light components from being introduced into the light guide 2. , thus only good quality and safe visible light will be introduced into the light guide. Also, according to this embodiment, the lens 1
Since the transparent fluid passage 3 is disposed in front of the light guide, there is no need to provide a hole for inserting the light guide 2 into the fluid passage, and the construction of the fluid passage becomes simple and inexpensive. There are also advantages such as ease of assembly work.
