Abstract

PURPOSE:To semipermanently use by transmitting a solar light via an optical fiber mounted particularly on the top of a mountain or in the ocean and connected to a solar light collector, and incorporating a solar battery for receiving the solar light in a sealed chamber. CONSTITUTION:A solar light collector 1, an optical fiber cable 2 in a cylinder, a solar battery unit containing chamber 3, etc., are provided. The chamber 3 is so disposed that a solar battery unit 6 is extended on the whole periphery of its room, and a convex mirror 7 is mounted on a bottom in such a manner a solar light radiated from the cable 2 is efficiently arrived at the unit 6 and maximum generation is executed with a minimum space. The solar battery is used as a power source for an observation system mounted on the top of a mountain or in the ocean, and the unit 6 is contained in the chamber. Thus, the life of the battery can be semipermanently held without influence of external environments.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a solar cell power supply system, and particularly to a solar cell power supply system used as a power source for observation points installed on mountain tops or in the ocean where transportation is inconvenient.

[Conventional technology]

Conventionally, the power supply system for this type of observation device uses primary or secondary batteries such as lithium or nickel cadmium batteries.
Additionally, some floating observation buoys and land observation systems used solar battery units.

[Problem to be solved by the invention]

The conventional power supply systems for mountaintop observation equipment and ocean observation buoys mentioned above rely on regular replacement or charging of primary or secondary batteries, or supply power via power cables, but these methods are economical in terms of maintenance. Not on point. On the other hand, as a semi-permanent method using solar cells, there are
Alternatively, solar cells are attached to the outer shell of an observation buoy to directly receive sunlight and generate electricity, but at this time the solar cells are exposed to the external environment, such as wind, rain, dust, snow, and especially on the sea surface.
The drawback is that the efficiency of solar cells deteriorates in a short period of time due to waves, salt damage, attached dust, etc.

An object of the present invention is to provide an economical solar battery power system that can be used semi-permanently.9 [Means for Solving the Problems] The solar battery power system of the present invention includes a solar power concentrator,
It includes an optical fiber connected to this solar light concentrator and a sealed chamber that houses a solar cell that receives sunlight transmitted through this optical fiber.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a perspective view of a first embodiment of the present invention applied to an observation hat installed in a remote location such as a mountain top.

In the figure, 1 is a solar light concentrator, 2 is an optical fiber cable in the cylinder, 3 is a solar battery unit storage room, 4 is a secondary battery room for daytime charging, and 5 is an observation equipment and data to the observation center. This is an observation equipment room that houses the transmitting communication equipment.

A solar cell unit 6 is stretched around the entire periphery of the room, a convex mirror 7 is placed on the bottom, and an optical fiber cable 2 is placed on the bottom of the room.
The device is designed so that more radiated sunlight reaches the solar cell unit 6 efficiently and maximum power generation can be achieved in the smallest space. FIG. 3 is an explanatory diagram of the internal arrangement of another example of the solar cell unit housing chamber 3, which employs a method in which sunlight is scattered through the gap in the optical fiber cable 2.

FIG. 4 is a perspective view of a second embodiment of the present invention applied to an observation buoy installed in the ocean.

In Fig. 4, 11 is a solar concentrator device, 12 is an optical fiber cable in a cylinder, 13 is a solar cell unit storage chamber, 14 is a secondary battery chamber, 15 is an observation equipment room, and 16 is a weight for buoyancy balance. , 17 is a chain for fixation.

FIG. 5 is an explanatory diagram showing the internal arrangement of the solar cell unit storage chamber 13. Sunlight emitted from the optical fiber cable 12 is reflected by the convex mirror 18 on the bottom and reaches one solar cell unit attached around the entire periphery of the room.

〔Effect of the invention〕

As explained above, the present invention uses a solar battery as a power source for an observation system installed on a mountaintop or in the ocean, and by housing the solar battery unit indoors, the solar battery can be used without being affected by the external environment. It is possible to maintain the lifespan semi-permanently, eliminate wind and rain, waves, floating dust, and salt damage under adverse weather conditions, maintain the efficiency of solar cells, and provide a long-life solar cell power system. Furthermore, by using the solar cell power supply system of the present invention,
This has the effect of providing an observation system that is easy to maintain, economical, and highly reliable.
