In recent years, renewable energy sources (specifically, sunlight or wind or biomass or geothermal heat) that are stably supplemented by natural forces have attracted attention in various parts of the world.

Solar power generation, which is one of the power generation methods using such renewable energy, has fewer restrictions on the installation area than other power generation methods. In addition, it has almost no need for maintenance of the machine, so it attracts attention and large-scale solar power generation. Systems (also known as giant solar power plants) are built around the world.

Such giant solar power plants are built in dormant areas (for example, waste arable land or mountains) It is more common, but it is difficult to find a large dormant place to build the giant solar power plant. In addition, in the case of building a giant solar power plant in the mountainous area, land development must be carried out, and there will be problems of time or cost. In view of the above problems, as a method for solving the above problems, a method of arranging a solar panel in a state of floating in a pond or a lake or a sea or a river has been put into practical use as a device for implementing the above method (that is, solar energy) Various types of constructs have been proposed for the panel mounting floating table (for example, refer to Patent Document 1).

Fig. 11 is a perspective view showing an example of a conventional structure for a floating frame for solar panel installation, a symbol P for a solar panel, and a symbol 200 for a plastic case in which the solar panel (P) is supported in a tilted state. Reference numeral 300 denotes a connecting member (200) and a connecting member interposed between the outer casing (200) and the outer casing (200). The outer casing (200) is a body that can be closed by air to form a floating body, and as shown in detail in FIG. 12(a), has an ear portion (200a) protruding in a horizontal direction at four corners thereof, at the ear portion (200) 200a) is formed with a hole (for example, refer to FIG. 12(b) of the patent document).

The floating opening portion (12) that is disposed to penetrate in the vertical direction when floating on the water surface (A), and the standing support portion (11) are disposed in the floating portion (10). When the vertical position (11A) is erected upward, the solar panel (P) is supported to be inclined at a predetermined angle (θ); the bridge portion (15A, 15B) is not erected as described above. Position (11A) and the floating opening The position of the inside of (12) is accommodated in the storage position (11B) of the floating portion (10) to support the standing support portion (11), and the standing support portion (11) and the floating portion (10) The solar panel installation floating frame (1) is integrally formed, and the first molding die (17A) can form the floating portion (10) and the standing support portion (11) and has The second forming mold (17B) is formed along the gap portion (E) of the bridge portion (15A, 15B) along the gap portion (E) of the bridge portion (15A, 15B). The shape of the bridge portion (15A, 15B) can be formed together with the aforementioned first forming mold (17A).

According to an eleventh aspect of the present invention, as illustrated in FIGS. 9(a) and 9(b), the first molding die (17A) is used for molding without using the second molding die (17B). When the second molding die (17B) is used than when the injection material is filled in the gap portion (E), the thicker connecting portions (16A, 16B) can be formed.

According to a twelfth aspect of the present invention, the floating material (10a) having a specific gravity lower than that of water or seawater and buoyancy is filled inside the floating portion (10).

In addition, the symbols and the like in the parentheses are those that facilitate the representation of the corresponding elements in the drawings. Therefore, the description is not limited to those described in the drawings.

According to the first aspect described above, when the standing support portion (11) is disposed at the storage position (11B), the vertical support portion (11) is disposed at the vertical position (11A). The amount of protrusion from the standing support portion (11) of the floating portion (10) is small (that is, the state in which the standing support portion (11) is accommodated in the floating portion (10)) Before reaching the site where the floating panel for solar panel installation is installed, the floating panel for solar panel installation can be transported in an ideal cargo form, so that the number of floating panels for the solar panel that can be transported at one time is large, and the transportation cost can be reduced. . Further, the cold air from the water surface (A) reaches the solar panel through the floating opening portion (12), and the solar panel can be cooled, thereby suppressing an increase in temperature of the solar panel and suppressing a decrease in power generation efficiency accompanying the increase.

According to the second and third aspects described above, it is possible to attach the standing support portion (11) to the floating portion (10) in a simple operation, and to obtain a swing even when the floating portion (10) is long due to the wind. The above-described standing support portion (11) also has an effect of being easily detached from the floating portion (10).

According to the fourth aspect described above, the bracket or the bolt for fixing the solar panel is not disposed on the upper edge of the solar panel, and therefore, the number of parts (i.e., the number of brackets or bolts) can be correspondingly reduced. As a result, the cost can be reduced, and the work for fixing the aforementioned solar panel can be simplified.

According to the fifth aspect described above, the free movement of the mooring bar member (18) in the floating opening portion (12) is prevented, and the barge member (18) can be avoided for various members (for example) For example, the aforementioned solar panel) gives a state of damage.

According to the sixth aspect described above, the maintenance of the solar panel or the like can be performed by the pedal portion (100).

In the case where buoyancy is generated by filling the air, there is a loss of buoyancy in the case of the air leakage. However, according to the seventh and twelfth aspects described above, the buoyancy is maintained by the floating material (10a), so that there is no such loss of buoyancy.

According to the eighth and ninth aspects described above, even when the solar panel installation structure (D) floating on the water surface is shaken by water waves, each solar panel installation floating frame is less likely to be subjected to other solar panel installation floating frames. The action is restrained and can be relatively freely shaken on the water, which can alleviate or prevent the concentration of force from being concentrated at a specific location.

According to the tenth and eleventh aspects described above, the structures having different shapes can be separately manufactured by using only the difference of the second forming mold (17B) at the time of manufacture (that is, the above-mentioned standing support portion can be used). (11) The floating panel for solar panel installation that can be easily removed, and the floating panel for solar panel installation that cannot be easily removed by the standing support portion (11) are not completely different for manufacturing both products. It is necessary to form a mold, and therefore, the manufacturing cost can be reduced accordingly.

Hereinafter, an embodiment of the present invention will be described with reference to Figs. 1 to 10 .

The floating panel (1) for solar panel installation according to the present invention is provided in a state in which the solar panel (P) is floated on a water surface or a sea surface (refer to symbol A. Hereinafter, simply referred to as "water surface"). The floating portion (10) is configured to float on the water surface (A), and the standing support portion (11) is configured to be detachably disposed at a standing position that is erected upward from the floating portion (10) ( 11A).

In addition, the floating portion (10) has an opening portion that is disposed to penetrate in the vertical direction when floating on the water surface (A) (see reference numeral 12 in FIGS. 2 and 3. Hereinafter, referred to as "floating opening portion") . Further, the standing support portion (11) is configured to support the solar panel (P) at a position higher than the water surface (A) when disposed at the standing position (11A). Further, the standing support unit (11) is configured to support the solar panel (P) so as to be inclined at a predetermined angle (θ) (see FIG. 1). In addition, the standing support portion (11) is as shown in Fig. 4 (a) and Fig. 4 (b) exemplified, disposed inside the floating opening portion (12), and configured to be able to obtain a housing position (11B) accommodated in the floating portion (10).

Further, when the standing support portion (11) is disposed at the storage position (11B), the arrangement can be made from the foregoing when the standing support portion (11) is disposed at the standing position (11A). The standing support portion (11) of the floating portion (10) has a small amount of protrusion (that is, the state in which the standing support portion (11) is accommodated in the floating portion (10)), and the solar panel is disposed at the arrival. Before the installation of the floating gantry, the solar panel installation floating gantry can be transported in an ideal cargo form, so that the number of floating gantry for the solar panel that can be transported at one time is large, and the transportation cost can be reduced. Further, the fixing support portion (11) can be fixed to the storage position (11B) by using a known locking mechanism (for example, a concave portion or a convex portion is formed at an appropriate position of the floating portion (10). The standing support portion (11) is locked to the locking portion of the concave portion or the convex portion, or a locking mechanism such as a joint or a pin or a jig, but the standing support portion (11) is located at the storage position ( The state of the state of 11B) may be produced by molding the solar panel installation floating frame (1) (details will be described later).

Here, the floating portion (10) may have buoyancy by filling air in the airtight case, but has a specific gravity lower than that of water or sea water to cause buoyancy to generate a floating material (refer to FIG. 1). 10a, for example, foamed styrene, etc.) is preferred. Specifically, it is preferable that the outer wall of the floating portion (10) is formed into a shell shape with a strong resin, and the floating material (10a) is preferably filled inside the outer wall. Further, the filling of the floating material (10a) may be performed simultaneously with the formation of the outer wall, but may be performed after the outer wall is formed. When using the floating material (10a) as described above, compared to air In the case of ensuring buoyancy, the buoyancy becomes less likely to be lost, and the solar panel (P) can be held on the water surface for a long period of time.

As a structure for detachably arranging the said standing support part (11) in the said standing position (11A), various structures are mentioned. For example, a concave portion (not shown) or a hole portion (also not shown) may be provided at an appropriate position of the floating portion (10), and the standing support portion (11) may be inserted into the concave portion or the hole portion, or A convex portion (not shown) is provided at an appropriate position of the floating portion (10), and the standing support portion (11) may be supported by the convex portion. Preferably, the floating portion (10) is provided with a rail portion (see FIGS. 13(a) and 13(b), symbol 10d), and an embedded portion is formed in the standing support portion (11) (see FIG. 13(c) and 13c) of FIG. 13(d) are slidably fitted into the rail portion (10d), and the rail portion (10d) is fitted into the rail portion (10d), and the standing support portion (11) The configuration is such that the floating portion (10) is supported in a state in which the standing position (11A) is obtained. In this case, the rail portion (10d) is formed to extend in the substantially horizontal direction (x direction) when the floating portion (10) floats on the water surface (A), and is configured to be in the standing support portion ( 11) When the solar panel (P) is supported at the stand-up position (11A), the fitting portion (11c) of the standing support portion (11) becomes slippery due to pressing on the rail portion (10d) (That is, it is preferable that the aforementioned embedding portion (11c) does not intend to slide on the rail portion (10d). When it is formed as described above, the standing support portion (11) can be attached to the floating portion (10) by a simple operation, and even if the floating portion (10) is rocked for a long period of time due to the wind, the standing portion can be obtained. It is also difficult to prevent the support portion (11) from falling off from the floating portion (10). Further, as shown by reference numerals 10g and 10h in FIGS. 1, 4, and 5, on the upper surface (10i) of the floating portion (10) (that is, the floating portion (10) floats above the water), At least a pair of protrusions are formed to sandwich the standing support portion (11) located at the stand-up position (11A). The pair of protrusions (10g, 10h) are provided in a direction in which the rail portion (10d) extends (that is, in the x direction). Further, the protrusion (10g) disposed on the upstream side in the direction in which the standing support portion (11) is inserted into the rail portion (10d) (that is, the -x direction) has a tilt as shown in FIG. The surface (10g1) is smoothly inclined; the horizontal plane (10g2) is formed substantially horizontally; the support surface (10g3) supports the above-mentioned standing support portion (11), and the standing support portion (11) is inserted into the rail portion ( At 10d), one of the lower portions of the standing support portion (11) slides on the inclined surface (10g1) and the horizontal surface (10g2), and then moves to the standing position (11A). Further, the other protrusion (10h) has a support surface (10h3) supporting the standing support portion (11), and a support surface (10g3) of the support surface (10h3) and the protrusion portion (10g) The standing support portion (11) is clamped together, and the standing support portion (11) is firmly supported.

On the other hand, the standing support portion (11) disposed in the vertical position (11A) is configured to support the solar panel (P) at a predetermined angle (θ). The standing support unit (11) has a need to form a locking portion for locking the solar panel (P). As the most preferable aspect, the locking portion (11b) that supports the solar panel (P) by inserting one of the solar panel (P) (see the symbol Pa of FIG. 5) is preferable. The slit portion (11b) is preferably formed in the vicinity of the upper end portion of the standing support portion (11). Specifically, a substantially L-shaped hook portion (Pa) is formed on the upper edge portion of the solar panel (P), and the hook portion (Pa) may be preferably inserted into the slit portion (11b). In addition, a spacer portion (for example, a plate-like portion having a thickness of about 10 mm and a thickness of about 2.5 mm) 19 is disposed on the lower side of the hook portion (Pa) inserted into the slit portion (11b), and the solar panel is suppressed. (P) looser than ideal. The spacer portion (19) may be integrally formed with the floating portion (10) or the hook portion (Pa), but may be formed separately from the floating portion (10) or the hook portion (Pa). Further, it is preferable that the lower edge portion of the solar panel (P) is fixed to the floating portion (10) by a bracket or bolt of a suitable shape. In the case where it is fixed as described above, it is sufficient that the bracket or the bolt is disposed on the lower edge portion of the solar panel (P), and is not disposed on the upper edge portion of the solar panel (P), so the number of parts can be (ie, the number of brackets or bolts) is correspondingly reduced. As a result, the cost can be reduced, and the work for fixing the aforementioned solar panel can be simplified.

On the other hand, as shown in FIG. 2 and FIG. 6, a notch, a hole, or the like (hereinafter referred to as a "locking portion for parking") (10c) is formed in the edge portion of the floating opening portion (12), and The parking locking portion (10c) enables a long member (for example, a flexible fiber rope, a flexible metal metal rope, or a resin or metal chain) In the following, it may be referred to as a "long bar member for parking" (18). Further, one end of the mooring member (18) is fixed to a fixture member fixed to a lakeshore or a coast (not shown). It is preferable that the solar panel installation floating frame (1) is parked at a predetermined position of the water surface (A) by the mooring bar member (18). In this case, the mooring long member ( 18), the side of the floating panel (1) for solar panel installation is locked to the parking locking portion (10c), thereby preventing the mooring member (18) in the floating opening portion (12) The freedom of movement can avoid the mooring member (18) for various components (for example, the aforementioned solar panel (P) In the case where the floating portion (10) is carried by the operator in a hand, it is easier to put the operator's own body or arm or hand into the floating opening portion (12). Hand-held handling. Further, a portion indicated by the symbol 10e or 10f in Fig. 13(a) is concave. In the trap portion, the above-described mooring bar member (18) is locked to the recess portion (10e, 10f) to prevent the offset of the mooring bar member (18). Further, a slit-shaped recessed portion is formed in the lower portion of the floating portion (10), and the claw of the forklift elevator may be inserted. Further, the floating portion (10) may be held by the slit-shaped recessed portion. For example, in the case where it is necessary to place the floating portion (10) on an inclined position or the like, it is preferable to hold the floating portion (10) by the slit-shaped depressed portion.

As illustrated in FIG. 3, when the horizontal direction along the position of the water surface (A) is referred to as the x direction, and the other horizontal direction orthogonal to the x direction is referred to as the y direction, the floating portion (10) a pedal portion (100) extending in the x direction to a position not covered by the solar panel (P) supported by the standing support portion (11), and configured as an upper surface (100a) thereof In other words, at least a portion of the upper surface of the portion of the solar panel (P) that is not supported by the vertical support portion (11) is formed to be substantially flat and function as a pedal. .
