Abstract

A buoy for solar power generation is provided that can selectively utilize either a holding function for a solar power generation panel or a footrest function. The buoy (20) can be used by floating either the front side (20F) or the back side (20B). The front side (20F) can be mounted with a first fixing component (81) for holding a solar power generation panel (60), and the back side (20B) has a non-slip convex portion (28) for walking. Since the buoy can be used to float the front side (20F) on the water to serve as a holding component for the solar power generation panel, and the back side (20B) can be floated on the water to serve as a footrest (120), the manufacturing cost of the buoy is reduced.

The problem to be solved by the invention

In Patent Documents 1 and 2, the degree of freedom in the arrangement of dedicated buoys with respect to solar power generation panels is low. That is, among the solar panel placement buoys, sometimes it is not possible to place the solar panel installation floats in response to shape changes occurring near the shore of a pond, and sometimes it is not possible to place the maintenance buoys. As a result, the arrangement of solar power generation panels is limited, and the amount of power generation is less than expected. In addition, the following situation should be considered: the maintenance of the solar power generation panel cannot be performed, which will cause adverse situations such as a decrease in power generation.

In addition, in the method of producing a dedicated buoy according to the shape change occurring near the shore such as a pond, the cost increases due to the production of molds and the like every time.

In addition, maintenance buoys need to be connected to other buoys. In the method of mooring with ropes, etc., when walking on the buoy, the swing will increase and become unstable. If a connection structure is installed, the stability of the buoy will be improved. The price of the mold of the buoy increases, the cost increases, and the degree of freedom of connection decreases.

An object of the present invention is to provide a solar power generation buoy capable of selectively utilizing either the holding function of a solar power generation panel or the function of a foot platform, and a solar power generation unit using the same.

means to solve the problem

The present invention is a buoy for solar power generation that floats on water and holds a solar power generation panel. Moreover, the buoy is characterized in that it has a holding part for holding the solar power generation panel on the front, and has an anti-slip protrusion when walking on the back of the opposite side of the front, so that the front and the back can be It can be used by floating on any side of the water.

Invention effect

The solar power generation buoy according to the present invention can be used by floating either one of the front side having a holding portion for holding a solar power generation panel and the back side having an anti-slip convex portion for walking. Since one type of buoy can be used as a holding member for a solar power generation panel by floating the back surface on water, and as a footrest by floating the front surface on water, the degree of freedom in use of the buoy is improved. As a result, the manufacturing cost of the buoy is reduced, and a solar power generation unit can be configured at low cost.

The buoy of the embodiment can be used by floating any one of the front 20F and the back 20B, the front 20F can be attached with the first fixing part 91 for holding the solar power generation panel, and the back 20B has anti-slip protrusions for walking. 28. Since one type of buoy can be used as a holding member for the solar power generation panel by floating the front side on water, and as a footrest by floating the back side on the water, the manufacturing cost of the buoy is reduced, and the solar power generation unit can be constructed at low cost. In addition, the hollow buoy 21 can be configured as a ballast by making the inside of the buoy hollow without filling the case with foamed resin. Therefore, the production cost of the buoy can be reduced, and a solar power generation unit can be configured inexpensively.

In the embodiment, since a solar power generation unit of any shape can be configured by appropriately combining buoys of one type of specification and walking boards, it is also possible to cope with complicated shapes such as lakesides. When transporting for installation work, only buoys of the same specification can be transported, so the transport efficiency is high. In addition, even if the buoy for holding the solar power generation is damaged, the buoy as the footrest can be turned over and used as a buoy for holding the solar power generation panel, so it is not necessary to store spare parts on site in advance.
