Abstract
Description
Technical Field

[0020] As shown in FIG. 1, a protection device for an offshore solar power generation facility according to an embodiment of the present invention includes a base unit 1 and a protection unit 2 provided on the base unit 1.
[0021] As shown in FIGS. 1 and 2, the base unit 1 includes a plurality of pedestals 11, a plurality of tubular portions 12, a plurality of support frames 15, and a plurality of tread plates 16.
[0022] As shown in FIG. 1, the plurality of pedestals 11 are arranged at intervals along the first direction L1.
[0023] Also, as shown in FIGS. 1 and 3, each pedestal 11 has both end portions along the second direction L2 orthogonal to the first direction L1, and a plurality of through holes 110 that are spaced apart along the second direction L2 between the both end portions and are respectively arranged so as to extend and penetrate in the first direction L1.
[0024] In this embodiment, since the pedestal 11 exists as the base of the protection device according to the present invention, it is preferably made of a material having good rigidity.
[0025] As shown in FIGS. 1 and 3, each tubular portion 12 extends so as to pass through the corresponding through hole 110 in each pedestal 11.
[0026] In this embodiment, the length of each tubular portion 12 can be selected according to needs, and is configured to have a body structure that extends along the first direction L1 together with a sufficient number of pedestals 11 arranged at appropriate distances along the first direction L1.
[0027] As shown in FIGS. 1 and 3, each support frame 15 is disposed between two adjacent tubular portions 12 and supports a tread plate 16 described later.
[0028] As shown in FIG. 1, each tread plate 16 is provided on a plurality of support frames 15. When performing maintenance, an operator can step on these tread plates 16 and walk on them.
[0029] As shown in FIGS. 1 and 3, the protection unit 2 includes a side frame 21, at least one shielding plate 22, and at least one suspension member 23.
[0030] As shown in FIGS. 1 and 3, the side frame 21 is connected to one end of either of both ends along the second direction L2 of each pedestal 11.
[0031] At least one shielding plate 22 is a rigid plate. As shown in FIGS. 1 and 3, it is fixed to the side frame 21 and has a plurality of ventilation holes 220 (see FIG. 1) that penetrate along the second direction L2.
[0032] As shown in FIG. 3, at least one suspension member 23 is for fixing at least one shielding plate 22 to the side frame 21.
[0033] In this embodiment, the suspension member 23 is arranged on the side frame 21, and the above-described shielding plate 22 is hung on the suspension member 23 and fixed to the side frame 21. However, it is not limited thereto.
[0034] In this embodiment, the shielding plate 22 is a rigid plate and can be easily assembled by the suspension member 23. Also, a plurality of both the shielding plate 22 and the suspension member 23 are provided.
[0035] As shown in FIGS. 2 and 5, a protection system for an above-water solar power generation facility according to an embodiment of the present invention includes a plurality of protection devices according to the above-described embodiment and a plurality of connection modules 3.
[0036] As shown in Fig. 2, a plurality of protection devices are arranged adjacent to each other so as to be able to protect the solar power generation device 8.
[0037] As shown in Figs. 2 and 5, each connecting module 3 includes a connecting member 32 and a plurality of bent pipes 31.
[0038] The connecting member 32 is arranged to interconnect the side frames 21 in two adjacent protection devices.
[0039] In this embodiment, as shown in Figs. 2 and 5, a plurality of protection devices are interconnected by a connecting member 32 to surround the internal area Z. The solar power generation device 8 is located in the internal area Z as shown in Fig. 2 and can be protected by those protection devices.
[0040] Here, the solar power generation device 8 is, for example, a module composed of a floating solar power generation panel, or a floating photovoltaic box equipped with a transformer, an inverter, a boost converter, a capacitor, etc.
[0041] As shown in Fig. 5, at least one shielding plate 22 in each protection device is arranged adjacent to the internal area Z, that is, the shielding plate 22 is arranged inside the protection device. A plurality of tubular parts 12 in each protection device are arranged at intervals from each other in a direction away from the internal area Z.
[0042] As shown in Figs. 5 and 6, each bent pipe 31 is configured in a bent tubular shape. And as shown in Fig. 5, one end of each bent pipe 31 is connected to the end of the corresponding tubular part 12 in one protection device, and the other end is connected to the end of the corresponding tubular part 12 in another protection device adjacent to the above-mentioned one protection device.
[0043] More specifically, in the present embodiment, as shown in FIG. 6, each bent pipe 31 is configured to bend vertically. Moreover, at both ends of each bent pipe 31, there are extension portions 311 integrally formed with the main body portion of the bent pipe 31. The extending directions of the two extension portions 311 in each bent pipe 31 (shown by dashed-dotted lines in FIG. 6) are orthogonal to each other. Of course, here, it is not limited thereto, and in other embodiments, each bent pipe 31 may bend at other angles according to needs.
[0044] In the present embodiment, a plurality of the protection devices according to the present embodiment can be connected to each other by engaging the end of the tubular portion 12 with the extension portion 311 of the corresponding bent pipe 31.
[0045] As shown in FIGS. 2 and 5, since the shielding plate 22 in each protection device is arranged adjacent to the internal region Z, effective protection can be provided for the solar power generation device 8 in the internal region Z.
[0046] In the present embodiment, as shown in FIGS. 2 and 5, in the protection system for the floating solar power generation facility, the number of protection devices is four, and accordingly, the number of connection modules 3 is four. Also, each base unit 1 of the protection device has three tubular portions 12, and accordingly, the number of bent pipes 31 in each connection module 3 is three. Of course, here, it is not limited thereto, and in other embodiments, their numbers can be changed according to needs.
[0047] When assembling the protection system for the floating solar power generation facility according to an embodiment of the present invention, a plurality of the protection devices according to the present embodiment are connected to each other using a plurality of connection modules 3 in waters near the land to form the protection system for the floating solar power generation facility according to the present embodiment. Next, the protection system is moved by a ship to a predetermined location in waters farther from the shore. Then, the protection system is positioned at the predetermined location using a configuration such as an anchor.
[0048] In the protection system according to this embodiment, a plurality of protection units 2 are used, and their shielding plates 22 are connected to each other by a connecting member 32. That is, since the internal area Z is surrounded by a plurality of shielding plates 22, strong winds blowing from the periphery of the protection system can be partially blocked by the plurality of shielding plates 22 surrounding the internal area Z.
[0049] Moreover, when the protection unit 2 is subjected to strong winds, since the airflow hitting the shielding plate 22 passes through the plurality of ventilation holes 220 formed in the shielding plate 22, it is possible to effectively prevent the protection device from falling or being damaged. That is, it is possible to achieve the effect of reducing the influence of strong winds.
[0050] Not only that, in waters relatively far from the shore, it is inevitable for waves to rise. However, by arranging the plurality of pedestals 11 and the plurality of tubular portions 12 in the base unit 1 on the water surface, as shown in FIG. 4, from the perspective of each protection device, a configuration consisting of a plurality of pedestals 11 arranged at intervals in the first direction L1 can effectively realize wave dissipation against the waves along the first direction L1, while a configuration consisting of a plurality of tubular portions 12 arranged at intervals in the second direction L2 can also effectively realize wave dissipation against the waves along the second direction L2.
[0051] In this way, no matter from which direction the waves come, the protection system of this embodiment can dissipate the waves against them. Therefore, the influence of the waves on the protection system of this embodiment can be greatly reduced, and the stability of the protection system above the water surface can be significantly improved.
[0052] In summary, according to the protection device and protection system for floating solar power generation equipment according to the present invention, since wave dissipation and wind shielding can be effectively performed in floating solar power generation equipment, the solar power generation device 8 in the internal area Z surrounded by a plurality of protection devices can be effectively protected.
[0053] In the above, many specific details have been shown in order to facilitate an overall understanding of the present invention. However, it is obvious to those skilled in the art that one or more other embodiments can be implemented without showing specific details.
[0054] As described above, the preferred embodiments and variations of the present invention have been explained. However, the present invention is not limited to these, and all modifications and equivalent configurations are included as various configurations within the spirit and scope of the broadest interpretation.
