[0002] When constructing photovoltaic floating systems in water environments such as mudflats, the special geographical environment of the mudflats needs to be taken into consideration. Mudflats refer to the tidal zone between the high tide and low tide of coastal tides, and the beaches between the normal water level and flood level of rivers and lakes. Therefore, at high tide, seawater covers the seabed, and at low tide, the seawater recedes, exposing the seabed. Since the texture of the seabed is extremely soft and not easy to transport, it is necessary to use seawater to transport the materials of the photovoltaic floating system to the installation site at high tide.

[0003] The existing photovoltaic floating system has a complex structure and is heavy. After the materials are loaded onto the ship, the ship has a large draft. Even at high tide, the water depth of the mudflat is not sufficient to support the material transportation of the photovoltaic floating system. Utility Model Content

[0004] The purpose of the present application is to provide a raft-type photovoltaic floating system, which can simplify the structure of the raft-type photovoltaic floating system, reduce the transportation weight, facilitate the transportation of materials of the raft-type photovoltaic floating system to a tidal flat with a shallow water level, and improve the utilization rate of the tidal flat.

[0012] In an optional embodiment, the floating raft photovoltaic floating system further includes a fixing assembly, wherein the fixing assembly includes a plurality of fixing members, each of the fixing members is fixedly connected to the purlin and forms a receiving groove for the photovoltaic panel to be placed therein.

[0036] In this application, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements.

[0038] Embodiment 1

[0039] This embodiment is applicable to aquatic environments such as mudflats, which have the special geographical phenomenon of tides, that is, the periodic movement of seawater under the action of the tidal force of celestial bodies (the moon and the sun). The rise and fall of the sea surface in the vertical direction is defined as the tide. When the tide is high, the sea surface continues to rise to the high tide level, and the seawater will cover the seabed. When the tide is low, the sea surface continues to drop to the low tide level, the seawater recedes, and the seabed is exposed.

[0040] It is understandable that the seabed is muddy and extremely soft due to the influence of tidal phenomena. In addition, even at high tide, the water depth is shallow and heavy ships cannot enter the mudflat area, especially at low tide, when material transportation by ships is more difficult.

[0041] See also Figure 1 This embodiment provides a floating raft photovoltaic floating system. The floating raft mentioned here refers to a raft floating frame. Specifically, the floating raft photovoltaic floating system includes a supporting component, a floating component and a photovoltaic component.

[0042] The support assembly includes a plurality of support members 100 arranged at intervals along a first direction, that is, a plurality of support members 100 are linearly arranged along the first direction. In this embodiment, the end face of the support member 100 can be set as the tide surface, and the interval between two adjacent support members 100 forms a diversion channel 101. When the tide is high, seawater flows toward the tide surface and is diverted under the action of the diversion channel 101. On the contrary, when the tide is low, the seawater exits from the diversion channel 101.

[0043] Due to the particularity of high tide and low tide, the speed of seawater surge is relatively slow. Therefore, in this embodiment, the diversion channel 101 is set to divert the seawater into multiple streams, thereby achieving the purpose of reducing the impact of seawater on the floating raft photovoltaic floating system.

[0044] In addition, compared with setting the side surface of the support member 100 as the tide-facing surface, the present embodiment sets the end surface of the support member 100 as the tide-facing surface, which can greatly reduce the force-bearing area of ​​the floating raft photovoltaic floating system, further improve the stability of the present embodiment during the power generation process, reduce the shaking of the floating raft photovoltaic floating system, and increase the service life of the floating raft photovoltaic floating system.

[0045] For ease of description and understanding, in this embodiment, the first direction is set as the width direction of the floating raft photovoltaic floating system, and the floating raft photovoltaic floating system has a preset width value.

[0046] This embodiment provides a diversion channel 101 to greatly reduce the impact of seawater on the raft-type floating system in a diversion manner, avoiding excessive shaking of this embodiment, thereby improving the stability and reliability of the raft-type floating system.

[0047] To reduce the difficulty of the manufacturing process, the support member 100 of this embodiment is configured as a long strip. Specifically, the shape of the support member 100 includes but is not limited to a rectangular parallelepiped or a cylindrical shape. The end surface area of ​​the two ends of the support member 100 is smaller than any side surface area of ​​the support member 100.

[0048] The floating assembly includes a plurality of floating members 200, at least one of which is mounted on a support member 100. Since the support member 100 is configured as a long strip, multiple floating members 200 can be arranged on one support member 100 in this embodiment, thereby ensuring that the support member 100 has sufficient buoyancy and supporting force.

[0049] In this embodiment, a plurality of floating members 200 are arranged at intervals along the length direction of the support member 100 , that is, a row of floating members 200 are installed on one support member 100 .

[0050] In actual use, the floating member 200 includes a foam body and a metal shell. The foam body is light in weight, and the metal shell is in the form of a thin sheet. The metal shell is wrapped around the outer periphery of the foam body. On the one hand, the floating member 200 prepared in this embodiment is very light in weight. On the other hand, the metal shell has good corrosion resistance and can reduce the corrosion effect of seawater on the floating member 200.

[0051] The photovoltaic assembly includes a plurality of photovoltaic panels 300 and purlins 400, that is, there are multiple photovoltaic panels 300 and multiple purlins 400. The number of photovoltaic panels 300 and the number of purlins 400 can be adaptively adjusted according to actual needs, and there is no limit on the number.

[0052] A plurality of purlins 400 are arranged on the support members 100 at intervals along a second direction perpendicular to the first direction. In this embodiment, the length of each purlin 400 is equal to the width of the above-mentioned mid-floating raft photovoltaic floating system, that is, each purlin 400 is bolted to all the support members 100 .

[0053] In some other embodiments, there is no limit on the length of each purlin 400, and the lengths of the purlins 400 can be the same or different. It is understandable that as long as all the purlins 400 and the support members 100 are fixed, the purlins 400 and the support members 100 form a stable floating raft structure.

[0054] In this embodiment, the support member 100 and the purlin 400 form a floating raft structure, and the floating raft structure is used as a supporting component of the photovoltaic panel 300, which has good stability. The floating raft structure can be used for the growth and cultivation of aquaculture species and has good economic benefits.

[0055] Each photovoltaic panel 300 is mounted on at least two purlins 400. In this embodiment, two purlins 400 provide support for one photovoltaic panel 300. On the basis of meeting the installation requirements of the photovoltaic panel 300, the number of purlins 400 is reduced, saving installation costs. In addition, in this embodiment, the photovoltaic panel 300 and the floating member 200 are arranged opposite to each other, that is, the photovoltaic panel 300 is located above the purlin 400, and the floating member 200 is located below the purlin 400.

[0056] After installation, the backlight surface of the photovoltaic panel 300 is arranged close to the water surface, and under the buoyancy of the seawater, the photovoltaic panel 300 is substantially parallel to the sea surface.

[0057] After the installation is completed, the floating raft photovoltaic floating system can generate electricity, and because the floating raft photovoltaic floating system has a shading effect, it can effectively inhibit the growth of alien aquatic plants such as Spartina alterniflora, and reduce the adverse effects of alien aquatic plants on farmed species.

[0058] Specifically, during the high tide stage, the floating member 200 provides buoyancy for the raft-type photovoltaic floating system, so that the photovoltaic panel 300 is located above the sea surface, avoiding the negative impact of sea water on the photovoltaic panel 300. During the low tide stage, the floating member 200 slowly descends until the floating member 200 is supported between the seabed and the photovoltaic panel 300, ensuring that the photovoltaic panel 300 will not sink into the seabed.

[0059] In general, no matter in the high tide stage or the low tide stage, the present embodiment ensures the normal power generation of the photovoltaic panel 300 by disposing the floating member 200 .

[0060] Based on the above content, this embodiment further explains the transportation and installation principle of the floating raft photovoltaic floating system as follows:

[0061] S100. Load materials such as supporting components, floating components and photovoltaic components onto the vessel in different categories, and transport the materials to the installation site by vessel after high tide.

[0062] It is understandable that loading materials in different categories helps to improve the space utilization of the ship and achieve maximum utilization within the limited loading space. Loading materials in different categories can also help installers to efficiently obtain the required materials and reduce waste of work time.

[0063] In some other embodiments, considering the limited operating space of the vessel and the limited installation time, the support member 100 and the floating member 200 may be pre-installed before loading, and then the support member 100 and the floating member 200 may be loaded as a whole. For example, a plurality of floating members 200 may be first installed on a support member 100, and then a support member 100 and a plurality of floating members 200 may be loaded as a group.

[0064] S200. Assemble the support assembly, the floating assembly and the photovoltaic assembly, and place the raft-type photovoltaic floating system on the sea surface with the end surface of the support member 100 as the tide-facing surface.

[0065] Move your boat away from the installation site before low tide.

[0066] This embodiment composes a raft-type photovoltaic floating system through supporting components, floating components and photovoltaic components, simplifies the structure of the raft-type photovoltaic floating system, reduces the transportation weight, facilitates the transportation of materials of the raft-type photovoltaic floating system to the tidal flats with shallow water levels, and improves the utilization rate of the tidal flats.

[0067] Embodiment 2

[0068] See also Figure 2 and Figure 3 Based on the first embodiment, the present embodiment improves the structure of the purlin 400 , wherein the improvement is that the purlin 400 is made of a U-shaped profile, and each purlin 400 is respectively provided with a mounting surface 410 and a mounting groove 420 .

[0069] Each mounting surface 410 is located on the same horizontal plane, and each mounting surface 410 abuts against a corresponding photovoltaic panel 300 . In this embodiment, the mounting surface 410 is located on the upper surface of the purlin 400 .

[0070] The opening of the mounting groove 420 is arranged away from the support member 100 , that is, the mounting groove 420 is arranged upward, and the mounting groove 420 is arranged as a through groove.

[0071] The photovoltaic assembly also includes a plurality of fasteners 500, each of which is inserted into a corresponding installation groove 420 and fixedly connected to the support member 100. After the fastener 500 is installed, the fastener 500 is located in the installation groove 420, so that the fastener 500 is protected by the purlin 400 and avoids contact between seawater and the fastener 500 as much as possible, thereby ensuring the service life of the fastener 500.

[0072] According to the first embodiment: a plurality of support members 100 are arranged at intervals along a first direction, and the end faces of the support members 100 are used as the tide-facing surfaces, and a plurality of purlins 400 are arranged at intervals along a second direction perpendicular to the first direction. Therefore, the side surfaces of the purlins 400 are used as the tide-facing surfaces. Even if some seawater impacts the purlins 400, the side surfaces of the purlins 400 can still block the part of the seawater, thereby isolating the fasteners 500 from the seawater.

[0073] If some seawater still enters the purlin 400 , since the installation groove 420 is configured as a through groove in this embodiment, the seawater in the purlin 400 can flow out from both ends of the installation groove 420 under the impact and shaking of the external seawater.

[0074] In actual use, the fastener 500 is configured as a bolt, and the bolt passes through the installation slot 420 to achieve a fixed connection between the purlin 400 and the support member 100 .

[0075] This embodiment improves the structure of the purlin 400, which not only ensures the connection stability between the purlin 400 and the support 100 and the photovoltaic panel 300, but also improves the drainage performance of the floating raft photovoltaic floating system and extends the service life of the floating raft photovoltaic floating system.

[0076] Furthermore, the present embodiment further includes a reinforcement assembly, which includes a plurality of reinforcement members 600 . The reinforcement members 600 are disposed between two adjacent purlins 400 , and the reinforcement members 600 are disposed at an angle to each purlin 400 .

[0077] In this embodiment, a plurality of support members 100 and purlins 400 form a floating raft structure. The floating raft structure includes a plurality of units. Each unit is formed by separating two purlins 400 and two support members 100, and each unit is roughly rectangular. Each reinforcement member 600 is located in a unit and divides the unit into two triangles. According to the triangle stability principle, under the action of the reinforcement member 600, the unit has good stability, thereby improving the reliability of the floating raft structure.

[0078] Embodiment 3

[0079] See also Figure 1 Based on the above embodiment, the present embodiment improves the arrangement of the photovoltaic panels 300. The improvement is that a plurality of photovoltaic panels 300 are arranged in an array, and in a first direction, a first preset distance a is set between adjacent photovoltaic panels 300, and in a second direction, a second preset distance b is set between adjacent photovoltaic panels 300.

[0080] In this embodiment, the first preset distance a is equal to the second preset distance b, which improves the overall aesthetics of the arrangement of the multiple photovoltaic panels 300, makes the weight ratio of each part of the floating raft photovoltaic floating system uniform, and reduces the shaking of the floating raft photovoltaic floating system.

[0081] In some other embodiments, the first preset distance a is not equal to the second preset distance b. For example, the installer can calculate the first preset distance a based on the length of the purlin 400 and the number of photovoltaic panels 300. Then, the installer can also calculate the second preset distance b based on the sum of the distances between multiple purlins 400 and the number of photovoltaic panels 300 to ensure that the photovoltaic panels 300 are evenly installed on the purlins 400, so that this embodiment achieves a more reasonable weight distribution.

[0082] This embodiment improves the arrangement of the photovoltaic panels 300 to improve the uniformity of weight distribution of the floating raft photovoltaic floating system, ensuring that the floating raft photovoltaic floating system can float up or down stably during high tide or low tide.

[0083] Embodiment 4

[0084] See also Figure 2 and Figure 4 Based on the above embodiments, the present embodiment improves the fixing method of the photovoltaic panel 300. The improvement lies in that the floating raft photovoltaic floating system also includes a fixing assembly, which includes a plurality of fixing members 700. Each fixing member 700 is fixedly connected to the purlin 400 and forms a receiving groove 701 for the photovoltaic panel 300 to be placed.

[0085] Taking a solution of fixing a photovoltaic panel 300 on two purlins 400 as an example, both the left side and the right side of the photovoltaic panel 300 need to be fixed, and four fixing members 700 are required.

[0086] See also Figure 2 and Figure 5 For ease of description and understanding, the two purlins 400 are respectively defined as a first purlin 401 and a second purlin 402 , and the four fixing members 700 are respectively defined as a first fixing member 710 , a second fixing member 720 , a third fixing member 730 and a fourth fixing member 740 .

[0087] The first fixing member 710 fixes the left side and the first purlin 401 respectively, the second fixing member 720 fixes the left side and the second purlin 402 respectively, the third fixing member 730 fixes the right side and the first purlin 401 respectively, and the fourth fixing member 740 fixes the right side plate and the second purlin 402 respectively.

[0088] With the help of four fixing parts 700, the photovoltaic panel 300 can be firmly fixed on the two purlins 400. Since the mounting surfaces 410 of the purlins 400 are located on the same horizontal plane and the photovoltaic panel 300 is a rectangular structure, the light-facing surface of the photovoltaic panel 300 is basically parallel to the sea surface.

[0089] Please refer to Figure 2 , Figure 4 and Figure 5In order to prevent the photovoltaic panel 300 from shaking in the fixing member 700, the height of the receiving groove 701 can also be set to be the same as the thickness of the photovoltaic panel 300 in this embodiment. When the fixing member 700 and the purlin 400 are fixedly connected by bolts, the photovoltaic panel 300 is stably stuck in the receiving groove 701, and the up and down movement of the photovoltaic panel 300 is limited by the cooperation of the fixing member 700 and the purlin 400, and the left and right movement of the photovoltaic panel 300 is limited by the cooperation of two relatively arranged fixing members 700 (such as the first fixing member 710 and the third fixing member 730, the second fixing member 720 and the fourth fixing member 740).

[0090] This embodiment improves the fixing method of the photovoltaic panel 300 to improve the installation reliability of the floating raft photovoltaic floating system, thereby ensuring that the floating raft photovoltaic floating system can still maintain a good power generation state under the action of tides.

The improvement is that the floating member 200 includes a first floating portion 210 and a second floating portion 220 . The first floating portion 210 is located between the second floating portion 220 and the support member 100 .

[0093] The second floating portion 220 is cylindrical. On the projection plane, the projection of the first floating portion 210 is located within the projection of the second floating portion 220 , and the center of the second floating portion 220 is located on the projection plane.

[0094] The floating raft photovoltaic floating system further includes a clamp 800 assembly, which includes a plurality of clamps 800 , each of which is wound around a floating member 200 , and each of which is fixedly connected to the supporting member 100 .

[0095] Each clamp 800 includes a first clamping portion 810 and a second clamping portion 820 that are integrally formed. The first clamping portion 810 is wound around the floating member 200 , and the second clamping portion 820 is fixedly connected to the supporting member 100 .

[0096] This embodiment can also be set as follows: the first direction is the width direction of the support member 100, the second direction is the length direction of the support member 100, the support member 100 is configured as a wooden square, and the support member 100 is provided with a first side surface, a second side surface, a third side surface, a fourth side surface, and a first end surface and a second end surface, wherein the first side surface and the second side surface are parallel to each other, the third side surface is vertically adjacent to the first side surface and the second side surface respectively, and the fourth side surface is vertically adjacent to the first side surface and the second side surface respectively.
