Therefore, sunlight from the transmission pipe 38 passes through the glass column 48 in the axial direction, is reflected by the conical inclined surface of the enclosing part 500, and is emitted in the radial direction of the glass column 48. The sunlight can be efficiently dispersed and emitted into the closed container 44.

Also, pipes 52 and 54 are connected to the tote on the 1ljLII side of this airtight container 44 to constitute an inlet and an outlet of the light energy storage compound.
It is designed to move in the B force direction.

In this embodiment, the unsaturated hydrocarbon norbornadier/(hereinafter referred to as N-form) shown in FIG. 6 is used as a light energy storage compound. This N-isomer is a substance that changes into quadricycle/(hereinafter referred to as 9-isomer) through a photoreaction at room temperature when irradiated with short wavelength light in the ultraviolet region.
When the body passes through a catalyst (such as a cobalt tetraphenyl borophylline complex or a cobalt phthalocyanine complex), a catalytic thermal reaction occurs and the body returns to the N form. The state of ai from these 9 bodies to N bodies is 22 Kd /Mat (24QKcJ/
f) Generates back and forth fever.

Therefore, the N body sent into the sealed container 44 through the pipe 52 receives sunlight from the transmission pipe 38, undergoes a photoreaction, changes to -09 body, and is carried out from the pipe 54 to the outside of the sealed container 44. ing.

As shown in FIG. 1, the piping 54 connects to the catalyst device 6 installed in the hot water storage tank 60 via a Q-body metering tank 56 and a pipe 58.

The hot water storage tank 60 is provided with piping 70 at its lower part.
This piping 70 has a bo/p 72 in the middle and is shown in I1. The hot water tank 60 is connected to a water supply source that is not connected to the hot water supply tank 60, and water from the water supply source is sent into the hot water tank 60. A pipe 74 is provided at the top of the 60 hot water storage tanks and communicates with an air conditioning system, a hot water supply system, etc. (not shown).

Next, the operation of this embodiment configured as described above will be explained.

In the light collecting device 412, the light collecting unit 24 always follows the sun and collects the sunlight onto the solar fiber optic cable 32. This puff dollar optical fiber cable 32 sends concentrated sunlight to the transmission pipe 38, so that the sunlight reflects off the mirror surface inside the transmission pipe 38 and reaches the sealed container 44 in the basement 43.

The airtight container 44 is filled with N-body meter 66 by the operation of Bonpro 8.
The N bodies inside are fed into the transmission pipe 38 from its upper end.
When exposed to sunlight, it undergoes a photoreaction at room temperature and changes into nine forms. In this airtight container 44, sunlight that is evenly distributed from the transmission pipe 38 to the inner peripheral surface via the prism 46 moves toward the bottom while reflecting multiple times on the slanted inner angle surface, thereby increasing the efficiency of sunlight utilization. can be significantly improved.

The Q body generated in the closed container 44 passes through the piping 54 and is accumulated in the Q body reservoir 56 . This Q body utilizes chemical changes at room temperature, so there is no heat loss during storage, and the Q
The body storage device 56 does not require any heat insulating material and can be stored for a long period of several months or years. Furthermore, since the N-form and Q-form used in this example have a freezing point of 120° C. or lower, there is no risk of freezing.

The Q body in the Q body meter storage tank 56 is sent to the catalyst device 62 in the hot water storage tank 60 by operating the valve 58 when necessary. In this catalytic device 62, the Q-form changes into the N-form through a catalytic reaction, generating heat. Therefore, the temperature of the water in the hot water storage tank 60 is raised and it can be used for hot water supply, heating, cooling, power generation, etc.

Further, the N bodies generated in the catalyst device 62 are accumulated in the N body storage container 66 through a pipe 64, and are sent to the airtight container 44 by the bomber 8 when necessary.

In this way, in this embodiment, in addition to efficiently accumulating 11 ra of light, since the condensing device and the sealed container are connected by the transmission pipe 38, the light absorbing and heat dissipating main material, which is a heat medium, can be concentrated (11). There is no need to circulate or transport the product to the circulation 12, which simplifies the filling equipment and shortens the time required to pipe the product into a closed container. Furthermore, even if the light-absorbing and heat-radiating system is flammable or toxic, it can be safely stored in an isolated location such as a basement, thereby preventing accidents during use.

In the above embodiment, the light energy storage compound is norbornadien/, but the present invention is not limited to this. Any Mt or dynamic energy storage compound that can repeatedly release energy is applicable. Further, this optical energy storage compound is not limited to a fluid form, but may be a slurry form, and any form having fluidity can be used.

Further, in the above embodiment, a structure is shown in which the light concentrating device 12 and the transmission pipe 38 are connected by the optical 7-eyeper 30, but the end of the transmission pipe 88 is arranged in the condensing part of the condensing device 12, It is possible to enter the light directly into the transmission pipe 38. As a result, short wave (12) light in sunlight can also be effectively transmitted to the closed container 44 via the transmission pipe 38. The transmission pipe 38 can also adopt various connection structures other than the above-mentioned relay structure, and if possible, the condensing device and the closed container can be connected with a single transmission pipe such as a flexible synthetic resin. Good too.

Furthermore, the airtight container of this invention is not limited to the conical shape of the above embodiment, but may have various shapes such as a columnar shape, a block shape, etc., and the light output portion of the transmission pipe 38 communicates with the top of the airtight container. It is also possible to communicate with other parts such as the side surface.

It is preferable to disperse sunlight from the sealed container 44-it transmission pipe 38 and release it into the sealed container, and the emitted sunlight is reflected multiple times on the mirror surface inside the sealed container 44 to effectively irradiate the N body. This is desirable. For this purpose, the configuration may be such that the light from the transmission pipe is incident at an angle with respect to the perpendicular to the mirror surface.

Another embodiment of the transmission pipe is shown in FIG. The transmission pipe 138 in this embodiment includes a plurality of synthetic resin flexible tubes 80 (three in the illustrated example) to disperse sunlight and send it to the sealed container. The peripheral surface is a mirror surface such as AfA.

These flexible tubes 8o are thin-walled stems /L/ as outer tubes,
X It is inserted into the pipe 82, and mWs is possible.

A porous spacer 84 made of 11 asbestos or the like is filled between the stainless steel pipe 82 and the stainless steel pipe 82 . Therefore, the flexible tube 80 will not be damaged even when a load is applied from the outside, and peeling of the mirror surface can be prevented. Further, since the transmission pipe 138Fi steering/resistance pipe 82 is thin and flexible, it can be bent into any desired arrangement.

Even when the inside of the stainless steel pipe 82 and the inside of the flexible tube 8o are in a vacuum or reduced pressure state, the external pressure remains inside the stainless steel pipe 82.
Alternatively, since the spacer 84 supports it, the flexible tube 80 will not be significantly deformed.

Furthermore, since the transmission pipe 138 transmits sunlight in a dispersed manner, even if one of the flexible tubes 8o becomes unable to transmit sunlight, it is possible to transmit sunlight using another flexible tube.

1-I-Description [2] Since the energy storage device NFj according to the present invention connects a transmission pipe to a part of the closed container through which the light energy storage compound flows and emits light into the closed container, the heat medium length is It does not need to be circulated and transported over long distances, and has the excellent effect of improving the efficiency of light utilization and enabling long-term storage without loss during energy storage.
