Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to a solar cell mount installed on a liquid surface in the ocean, etc., and in particular, the solar cell receiving surface is always level without being affected by changes in the liquid level. This relates to a pedestal with a structure that is installed in the same state.

[Prior art and its problems]

To maximize the annual amount of light received on land, a solar cell mount on which a solar cell panel containing a large number of solar cells is installed should be placed so that its light-receiving surface is equal to the latitude of the land (this is called latitudinal angle installation). ) The solar panel 1 is installed at an angle.
(Fig. 6) However, in the case of offshore, it is difficult to install it at a latitude angle due to the effects of waves and swells, so it is generally installed horizontally on a floating liquid 2 such as a buoy. (Figure 7) However, when offshore, it is impossible to maintain a horizontal angle due to waves and swells. Therefore, the power obtained at that point changes instantaneously due to wave swells, and in order to obtain stable power, there is a problem in that solar cells with a capacity greater than that required for horizontal installation are required.

An object of the present invention is to solve such problems and provide a solar cell mount that can stably obtain electric power with a small number of solar cells.

[Means for solving problems]

In order to solve the above-mentioned problems, the present invention provides a solar cell mount installed on a liquid surface, which includes a first mount on which a solar cell is installed, and a second mount provided on the outer periphery of the first mount. and a third pedestal provided on the outer periphery of the second pedestal and having a buoyancy forming means,
a first shaft rotatably supporting the first mount inside the second mount; a first shaft provided in a direction perpendicular to the first axis and supporting the second mount inside the third mount; The second shaft is rotatably supported by the second shaft.

[Effect]

Since the present invention is configured as described above, the third pedestal having the buoyancy generating means swings following changes in the liquid level, but the first and second pedestals are rotatable about their respective shafts. Therefore, during the calm period, the first and second
The frame is in a horizontal state together with the third frame.

On the other hand, during pitching, which swings back and forth in the direction of wave propagation, or rolling, which swings from side to side, the first pedestal rotates via the first and second shafts and the second pedestal, so it is always in a horizontal state. maintained.

〔Example〕

Hereinafter, embodiments of the present invention will be described based on the drawings.

FIG. 1 is a perspective view showing a solar cell mount according to the present invention.

A plurality of solar cells 4 are attached to the surface of the pedestal 3, and the pedestal 3 is pivoted at its center and can be rotated in the direction of arrow A around a shaft 5, and is supported so that its surface is always in a horizontal position. has been done.

The solar cell 4 may be installed horizontally on the surface of the pedestal 3, or may be installed at a predetermined angle.

Reference numeral 6 is provided on the outer periphery of the pedestal 3 and is connected to the pedestal 3 via a shaft 5, and is connected to a pedestal 8 via a shaft 7 provided perpendicularly to the shaft 5. The frame is rotatable in the direction of arrow B by means of a shaft 7. 8 is a buoyancy forming means 9 such as a float at the bottom
It is a stand that swings to follow changes in the liquid level.

That is, since the frames 3, 6, and 8 are configured to be rotatable by the shafts 5, 7, one of the shafts 5, 7 functions as a pitting prevention shaft, and the other functions as a rolling prevention shaft.

The functions of the solar cell mount of the present invention are shown in Figures 2 to 4.
This will be explained according to the diagram.

FIG. 2 shows a calm state, and since the liquid level is calm at this time, the frames 3, 6, and 8 do not rotate and are maintained in a horizontal state.

FIG. 3 shows, for example, when the pedestal is in a pitting state due to liquid, and pedestals 8 and 6 follow the waves, but pedestal 3 is rotated by shaft 5 and maintained in a horizontal state. FIG. 4 is a side view of FIG. 3, and shows when the pedestal swings in an orthogonal direction, that is, in a rolling state.

At this time, the pedestal 6 is rotated by the shaft 7 with respect to the pedestal 8, and both the pedestal 3 and the pedestal 6 are maintained in a horizontal state.

As shown in FIGS. 3 and 4, even if the pedestal is pitched or rolled by waves, the pedestal 3 is always kept in a horizontal state.

Therefore, the solar cell 4 is always irradiated with stable light, and fluctuations in power are reduced.

The solar cell mount of the present invention can not only be installed directly on the liquid surface, but also be able to maintain the solar cell in a horizontal state even when attached to a ship as shown in FIG.

[Effect of idea]

As explained above, according to the present invention, even if the mount is in a rolling or pitching state due to changes in the liquid level, the solar cell light receiving surface can be kept constant, so it is suitable for use in mounts installed offshore. .
