[0002] A floating photovoltaic system is a system that arranges photovoltaic panels on the water surface for photovoltaic power generation. It usually includes a plurality of photovoltaic modules floating on the water surface, and each photovoltaic module can independently convert solar energy into electrical energy. In order to prevent other photovoltaic modules from being damaged when any one of the photovoltaic modules is struck by lightning, each photovoltaic module in the existing photovoltaic power generation system is usually grounded separately (electrically connected to the bottom ground, riverbed, etc.).

Detailed Description of the Specific Embodiment

[0025] The following describes the specific embodiments of the present disclosure in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only for the purpose of illustrating and explaining the present disclosure, and are not intended to limit the present disclosure.

[0026] In the present disclosure, unless otherwise stated, orientation terms such as "inside, outside", "upper, lower", "top, bottom" can be based on the structure of the relevant components themselves, or can be based on the orientation when the relevant components are used in cooperation. For example: the beam frame installed on the "upper side" of the floating part refers to the side of the beam frame away from the water surface of the floating part, that is, in the height direction, the beam frame is on the upper side of the floating part; the "top end" of the lightning rod is higher than the plurality of photovoltaic modules, and here the "top end" refers to the end of the lightning rod away from the water surface; one end is fixed to the "outside" of the barrel base, and here the "outside" refers to the outside of the accommodating space of the barrel base; the "bottom end" of the lightning rod is provided with a reinforcement base, which means that the reinforcement base is provided at the end of the lightning rod close to the water surface.

[0027] In the present disclosure, the terms "first", "second", etc. are used to distinguish one element from another, and do not have sequentiality and importance. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0028] Refer to Figure 1 - Figure 2 , the present disclosure exemplarily shows an offshore photovoltaic system, including a floating part 100 for floating on the water surface, a beam frame 200 installed on the upper side of the floating part 100, a plurality of photovoltaic modules 300 respectively installed on the upper side of the beam frame 200 and electrically connected to the beam frame 200, and an anchor block 520 installed with a vertical grounding electrode 530. Among them, the anchor block 520 is connected to the beam frame 200 through an anchor rope 510, and the beam frame 200, the anchor rope 510, the anchor block 520 and the vertical grounding electrode 530 are electrically connected in sequence. This "electrical connection" can be achieved through its own conductive material, or can also be achieved through wires, etc. The present disclosure does not limit this. It should be noted that the present disclosure does not limit the specific structure of the photovoltaic module 300, as long as it includes a photovoltaic panel and can convert solar energy into electrical energy. Since the structure and principle of the photovoltaic module 300 are well known to those skilled in the art, no further introduction is made here.

[0029] In the embodiments of the present disclosure, the floating part 100 may include a plurality of floating barrels 110 described below. In addition, in some other embodiments, the floating part 100 may also include foam blocks, air bags, etc., and the present disclosure does not limit this.

[0030] The present disclosure does not limit the specific structure of the beam frame 200, as long as it is located above the floating part 100 and can be used to install multiple photovoltaic modules 300. In an embodiment of the present disclosure, the beam frame 200 has conductivity so that the photovoltaic module 300 struck by lightning can conduct the high current to the beam frame 200 and further ground it through the anchor rope 510, the anchor block 520, and the vertical grounding electrode 530. Specifically, in an embodiment of the present disclosure, the beam frame 200 itself can be made of a metal conductive material, such as stainless steel, etc. In addition, the present disclosure does not limit the electrical connection manner between the photovoltaic module 300 and the beam frame 200. For example, in the embodiment shown in FIG. 1, the electrical connection between the photovoltaic module 300 and the beam frame 200 can be achieved through the second grounding wire 402. It should be noted that, Figure 1 Only one second grounding wire 402 is shown. In fact, a second grounding wire 402 can be provided between each photovoltaic module 300 and the beam frame 200.

[0031] It should be explained that, in an embodiment of the present disclosure, the vertical grounding electrode 530 can be prefabricated and fixed in the anchor block 520, and at least a part of the vertical grounding electrode 530 can protrude from the bottom surface of the anchor block 520. During use, the anchor block 520 is sunk to the bottom of the water, and the protruding part of the vertical grounding electrode 530 can be directly inserted into the bottom surface of the water bottom to achieve grounding, which is convenient and simple to use. In addition, in some other embodiments, the vertical grounding electrode 530 can also be detachably installed on the anchor block 520, and the present disclosure does not limit this. To ensure that the vertical grounding electrode 530 can be inserted into the ground of the water bottom, the lower end of the vertical grounding electrode 530 facing downward can be constructed in an arrow shape.

[0032] By using the above technical solution, multiple photovoltaic modules 300 are electrically connected to the beam frame 200 respectively. When any one of the photovoltaic modules 300 is struck by lightning, the photovoltaic module 300 can conduct its own high current to the beam frame 200 and further introduce it into the ground through the anchor rope 510, the anchor block 520, and the vertical grounding electrode 530 in sequence, avoiding damage to the remaining photovoltaic modules 300. Designed in this way, there is no need to ground each photovoltaic module 300 separately, and there is no need to construct complex grounding electrodes for each photovoltaic module 300 separately at the water bottom. When the anchor block 520 is lowered to the water bottom, the vertical grounding electrode 530 can achieve grounding, reducing the construction cost and the construction difficulty.

[0033] Referring to Figure 1 and Figure 2 , in an embodiment of the present disclosure, each photovoltaic module 300 can include a photovoltaic panel 310 and a bracket 320 supported between the photovoltaic panel 310 and the beam frame 200. By providing the bracket 320, it can be ensured that the photovoltaic panel 310 maintains a certain distance from the water surface, avoiding potential circuit hazards caused by the photovoltaic panel 310 being soaked in water.

[0034] Referring toFigure 1 In an embodiment of the present disclosure, the floating PV system may further include a lightning protection device 400 installed beside the PV module 300. The lightning protection device 400 may be electrically connected to the beam frame 200. By adding the lightning protection device 400, multiple PV modules 300 can be protected. The lightning protection device 400 can be used to attract lightning to itself and guide it to the ground through the beam frame 200, the anchor rope 510, the anchor block 520, and the vertical grounding electrode 530, reducing the probability that the PV module 300 is directly struck by lightning.

[0035] The present disclosure does not limit the number of the lightning protection devices 400. The specific number can be adaptively adjusted according to the number of PV modules 300, the coverage area of the PV modules 300, and the lightning protection performance of the lightning protection devices 400, and can specifically be 1, 3, 5, etc. Preferably, multiple lightning protection devices 400 are evenly distributed in the circumferential direction of multiple PV modules 300 to provide lightning protection for all PV modules 300.

[0036] The present disclosure does not limit the type of the lightning protection device 400. For example, in the embodiments shown in Figure 3 and Figure 4 the lightning protection device 400 may include: a support 410 detachably installed beside the PV module 300; and a lightning rod 420 installed on the support 410 and electrically connected to the beam frame 200 through a first grounding wire 401. Among them, the top of the lightning rod 420 is higher than multiple PV modules 300 to improve the protection effect of the lightning rod 420 on the PV modules 300. The lightning rod 420 can be grounded through the beam frame 200, the anchor rope 510, the anchor block 520, and the vertical grounding electrode 530, without the need to separately arrange a grounding line, reducing the construction difficulty and construction cost of grounding the lightning rod 420. In addition, in an embodiment of the present disclosure, the lightning protection device 400 is detachably installed beside the PV module 300. Such a design can facilitate the arrangement of the lightning protection device 400. It can be installed at the corresponding position according to actual needs, or when the installation position of the lightning protection device 400 needs to be changed, only its disassembly is required, and it can be reused. The operation is convenient and simple, and the flexibility is high.

[0037] In addition to the above-mentioned lightning rod 420, in some other embodiments, the lightning protection device 400 may also be a lightning protection strip, a lightning protection net, etc. The present disclosure does not limit it.

[0038] Referring to Figure 3 - Figure 4, in an embodiment of the present disclosure, the support 410 may include: a cylinder base; a connecting frame 413, one end of which is fixed to the outside of the cylinder base, and the other end is used for detachably connecting to the side of the photovoltaic module 300; and an insulating support ring 414, which is arranged on the upper side of the cylinder base, and a plurality of spaced-apart support rods 415 are supported between the upper edge of the cylinder base and the insulating support ring 414. Wherein, the bottom end of the lightning rod 420 passes through the insulating support ring 414 and extends to the middle position among the plurality of support rods 415. One end of the first grounding wire 401 is connected to the bottom end of the lightning rod 420, and the other end passes through the cylinder base and is connected to the beam frame 200. With such a design, the lightning rod 420 is fixed through the insulating support ring 414, and the bottom end of the lightning rod 420 is located among the plurality of support rods 415. This "hollowed-out" structure (formed by the plurality of support rods 415) can facilitate wiring, maintenance, and observation of the wiring position, etc., without the need to disassemble the lightning rod 420 for operation. In addition, the cylinder base can serve the dual functions of providing a wiring path for the first grounding wire 401 and supporting the lightning rod 420. The first grounding wire 401 passing through the inside of the cylinder base can protect the first grounding wire 401, prevent the first grounding wire 401 from being exposed to the air for a long time, and extend its service life.

[0039] The present disclosure does not limit the specific structure of the connecting frame 413. For example, in the Figure 3 and Figure 4 illustrated embodiment, the connecting frame 413 may include: a ceramic plate 4131, one end of which is fixed to the outside of the cylinder base; and a connecting plate 4132, which is fixed to the end of the ceramic plate 4131 away from the cylinder base, and the connecting plate 4132 is used for detachably connecting to the side of the photovoltaic module 300. Specifically, the connecting plate 4132 may be formed with a plurality of bolt holes for detachably connecting to the photovoltaic module 300. The connecting plate 4132 may be connected to the above-mentioned bracket 320, or may also be installed on the beam frame 200. The present disclosure does not limit this.

[0040] To improve the connection strength between the connecting plate 4132 and the ceramic plate 4131, referring to Figure 3 and Figure 4 , a reinforcing member 4134 may be provided at the connection position between the ceramic plate 4131 and the connecting plate 4132. The present disclosure does not limit the reinforcing member 4134. For example, it may be the Figure 3 and Figure 4 shown reinforcing inclined plate.

[0041] To facilitate holding the support 410, referring to Figure 3 and Figure 4 , in an embodiment of the present disclosure, a handle 4133 may be provided on the upper surface of the ceramic plate 4131.

[0042] To facilitate electrically connecting the first grounding wire 401 to the bottom end of the lightning rod 420, referring to Figure 3 andFigure 4 , in an embodiment of the present disclosure, a reinforcing base 430 may be provided at the bottom end of the lightning rod 420. The floating PV system may further include a conductive plate 440 installed on the bottom surface of the reinforcing base 430. A wire connection seat 450 is provided on the bottom surface of the conductive plate 440. The first ground wire 401 is connected between the wire connection seat 450 and the beam frame 200. With such a design, the current of the lightning rod 420 can flow to the beam frame 200 through the conductive plate 440, the wire connection seat 450, and the first ground wire 401 in sequence. The reinforcing base 430 can ensure the connection stability between the lightning rod 420 and the conductive plate 440.

[0043] Referring to Figure 3 - Figure 4 , in an embodiment of the present disclosure, the cylinder base may include a first cylinder base 411 and a second cylinder base 412 detachably sleeved on the upper side of the first cylinder base 411. The connecting frame 413 may be fixed to the outside of the first cylinder base 411. With such a design, when it is necessary to disassemble and repair the lightning rod 420, only the second cylinder base 412 can be detached from the upper side of the first cylinder base 411, without removing the entire support 410 from the PV system, and the operation is convenient and fast.

[0044] The present disclosure does not limit how the first cylinder base 411 and the second cylinder base 412 are detachably connected. For example, in Figure 3 and Figure 4In the illustrated embodiment, the upper edge of the first barrel base 411 may be provided with a plurality of positioning blocks 630 spaced from each other. Each positioning block 630 may be provided with a first positioning hole 640. The second barrel base 412 may be provided with a plurality of second positioning holes 650 corresponding to the respective first positioning holes 640. The floating photovoltaic system may further include: a plurality of positioning rods 660 sequentially passing through the respective first positioning holes 640 and second positioning holes 650; and a plurality of tension springs 670 sleeved on the respective positioning rods 660, and one end of the tension spring 670 is connected to the outer surface of the corresponding positioning block 630, and the other end is connected to the end of the positioning rod 660 facing away from the second barrel base 412. With such a design, when it is necessary to install the first barrel base 411 and the second barrel base 412 as a whole, the positioning rod 660 can be first pulled outward, and the second barrel base 412 can be inserted into the first barrel base 411, and the first positioning hole 640 and the second positioning hole 650 can be aligned. Then, when the external force is removed, under the action of the tension spring 670, the positioning rod 660 can move inward and pass through the first positioning hole 640 and the second positioning hole 650 to lock the first barrel base 411 and the second barrel base 412 together. On the contrary, when it is necessary to disassemble the second barrel base 412 from the first barrel base 411, only an external force needs to be applied to pull the positioning rod 660 outward to make the positioning rod 660 withdraw from the second positioning hole 650, and then the second barrel base 412 can be disassembled, and the operation is convenient and simple. In addition, in some other embodiments, the first barrel base 411 and the second barrel base 412 can also be detachably connected by bolts sequentially passing through the first positioning hole 640 and the second positioning hole 650.

[0045] To prevent the second barrel base 412 from moving axially downward relative to the first barrel base 411, resulting in a reduction in the height of the lightning rod 420, refer to Figure 4 , in the embodiment of the present disclosure, the first barrel base 411 may be sleeved on the outside of the second barrel base 412, and a bearing step 610 may be provided on the inner wall of the first barrel base 411, and the second barrel base 412 may abut against the bearing step 610. With such a design, when the second barrel base 412 is installed into the first barrel base 411, the bottom of the second barrel base 412 can abut against the bearing step 610 so as not to be able to move downward continuously. The present disclosure does not limit the bearing step 610, which may be an annular convex ring formed on the inner wall of the first barrel base 411, or may also be a plurality of convex blocks arranged at intervals in the circumferential direction on the inner wall of the first barrel base 411.

[0046] Refer to Figure 3 and Figure 4 , in the embodiment of the present disclosure, an anti-slip sleeve 620 may be sleeved on the outer periphery of the second barrel base 412. With such a design, when operating the second barrel base 412, the position of the anti-slip sleeve 620 can be held by hand to prevent slipping. The present disclosure does not limit the type of the anti-slip sleeve 620, which may be a rubber sleeve or the like.

[0047] The present disclosure does not limit the specific structure of the floating part 100. For example, in Figure 1 and Figure 2 the illustrated embodiment, the floating part 100 may include a plurality of pontoons 110, and the plurality of pontoons 110 may be respectively connected to the lower side of the beam frame 200. In addition, in some other embodiments, the floating part 100 may further include a plurality of air bags, foam blocks, etc.
