[0034] The core of the present invention is to disclose a bracket module to improve the installation stability and versatility of water surface photovoltaic components.

[0035] Another core of the present invention is to provide a water surface photovoltaic power station including the above-mentioned bracket module.

[0036] In order to make the technical personnel in this field better understand the scheme of the present invention, the embodiments of the present invention are described below with reference to the accompanying drawings. In addition, the embodiments shown below do not limit the content of the invention recorded in the claims. In addition, the entire contents of the structures represented by the following embodiments are not limited to those necessary for the solutions of the invention recorded in the claims.

[0037] like Figure 1 and Figure 2 As shown, the support module provided by the present disclosure is mainly used for supporting photovoltaic modules on the water surface to meet the power generation needs of photovoltaic modules; the support module mainly includes a first floating body 10, a second floating body 20 and a support rod 40, wherein the first floating body 10 and the second floating body 20 are arranged at intervals, and high-density polyethylene (HDPE) is usually used as the main material, so that the floating structure has the characteristics of low density, corrosion resistance, environmental stress cracking resistance (wind and wave, frost heave environment), water vapor permeability resistance, UV resistance, and no pollution to the water environment. The first floating body 10 and the second floating body 20 can provide an effective support structure through the buoyancy effect, and correspondingly, the support rod 40 is a rod structure and includes a first end 410 and a second end 420, the first end 410 of the support rod 40 is fixedly connected to the first floating body 10, and the second end 420 thereof is fixedly connected to the second floating body 20, so that the first floating body 10 and the second floating body 20 are connected as an integrated structure, and the support rod 40 is used to provide a structural setting foundation for the photovoltaic module.

[0038] In particular, in the support module provided by the present disclosure, the support rod 40 is in the form of a tube or a plate and includes a continuous bending portion 430. It should be noted that the tube may be a commonly used rectangular tube or round tube, and the support rod 40 is set as a tube or a plate so that the bending portion 430 can be formed by a bending structure, and the two ends of the bending portion 430 are integrally connected to other regions without generating a seam structure, which has higher strength and avoids impurities from splicing the seams and affecting the structural strength of the support rod 40. Furthermore, the height of the bending portion 430 in the vertical direction is higher than the first end 410 and the second end 420 of the support rod 40. Here, the vertical direction specifically refers to the direction perpendicular to the water surface when the support module is set on the water surface; compared with the currently commonly used C-shaped channel steel structure, the square tube, round tube or plate can be integrally processed into the bending portion 430 through a bending process, thereby providing an inclined support surface for the photovoltaic module, without the need to achieve the inclined setting of the support surface by splicing and fixing multiple beam structures. It should be noted that in this embodiment, the support rod 40 is preferably a square tube structure, which is a closed rectangle in its circumferential direction. It has a good rigidity effect in the direction perpendicular to any side wall, and can maintain the support effect on the photovoltaic module in a complex water surface environment. Compared with the C-shaped channel steel structure with an opening in the circumferential direction, it can improve the structural stability of the bracket module. The continuous bending portion 430 specifically refers to the area on the support rod 40 where the bending portion 430 is set as a non-spliced ​​structure. The C-shaped channel steel structure cannot be formed in one piece through the bending process. When it is necessary to support the photovoltaic module on an inclined surface, it needs to be spliced ​​with other structures to achieve the elevation of the photovoltaic module. The spliced ​​structure will have gaps and increase the number of connectors. It is very easy to rust and cause connection problems in a relatively humid environment on the water surface. In severe cases, it will cause the photovoltaic module to collapse the support structure. The present disclosure can reduce the number of connectors and the splicing gap in the bending area by processing the bending portion 430 into a non-spliced ​​structure through an integrated bending method, thereby improving the support stability of the bracket module for the photovoltaic module.

[0039] Furthermore, in order to improve the utilization efficiency of the support rod 40, the bending portion 430 on the support rod 40 in the present disclosure is arranged near the first end 410 of the support rod 40, that is, the support rod 40 is raised from a position near the first end 410, and the area between the bending portion 430 and the second end 420 of the support rod 40 is used to set the photovoltaic module, so that the photovoltaic module remains in an inclined state, which can increase the light receiving area of ​​the photovoltaic module and reduce the occupation of the water surface space. At the same time, the area between the bending portion 430 and the second end 420 is also provided with a plurality of mounting holes 440 for the photovoltaic module to achieve stable connection. The above structure forms a stable structure through the arrangement of the first float 10, the second float 20 and the support rod 40, which can withstand the weight of the photovoltaic module and the influence of environmental factors. The pipe or plate design of the support rod 40 and the continuous state of the bending portion 430 can have a more stable structural strength and avoid the problem of high failure risk in the water environment due to too many parts. According to the lighting conditions of the use scenario, support rods 40 with different bending angles and lifting heights can be easily produced through the bending process, so that the photovoltaic module can adapt to different installation environments and conditions, thereby increasing flexibility.

[0040] Furthermore, in order to enhance the fixed connection effect of the support rod 40 on the first float 10 and the second float 20 so as to provide a stable support structure for the photovoltaic assembly, in the present disclosure, a connecting portion 50 is provided on the first float 10 and the second float 20. The connecting portion 50 is a rigid structure, which can be a flat plate structure or a U-shaped plate structure. The end of the support rod 40 is connected to the connecting portion 50 to form a surface contact, and at least two connecting members are passed through the surface contact structure to lock the connection into an integrated structure.

[0041] Specifically, at least two connection holes are provided on a single connection portion 50 for fixing and connecting the ends of the support rod 40. Figure 6 and Figure 7 As shown, when it is a flat plate structure, it can be set on the top surface of the floating body in the vertical direction, and the docking and fixing of the support rod 40 are simpler; when it is a U-shaped plate structure, its bottom is set in contact with the top surface of the floating body in the vertical direction, and the opening is upward. At this time, one end of the support rod 40 is embedded in the groove structure of the U-shaped plate, and contacts with the three inner wall surfaces of the U-shaped plate, thereby achieving a larger area of ​​fit. At the same time, the support rod 40 can also be fixed to the U-shaped plate from the three inner wall surfaces of the U-shaped plate to enhance the end stable connection structure of the support rod 40.

[0042] Furthermore, with respect to the extension area of ​​the connection portion 50, the connection portion 50 can be provided only in a partial area of ​​the upper wall surface of the floating body, and only the installation space at the end of the support rod 40 needs to be met. In the present disclosure, the connection portion 50 surrounds the floating body, that is, the connection portion 50 is annularly structured and fixed on the circumferential outer wall of the floating body, so that the connection portion 50 and the floating body itself have a stable structure. Correspondingly, when the support rod 40 is fixed on the escalator, there is no need to distinguish between the front and back sides of the floating body, which can also reduce the difficulty of installing the support rod 40 and provide a flexible installation method.

[0043] In the above structure, if Figure 5 As shown, at least two fixing holes 510 are provided on a single connection part 50 to cooperate with the fixing of the end of the support rod 40, ensuring the connection effect of the support rod 40. At the same time, under the premise of meeting the strength support, the end of the support rod 40 can also extend the distance between the two floats and meet the support effect through the vacant part of the fixing hole 510, thereby allowing the bracket module to have higher flexibility and adjustment ability during the installation process. It should be noted that the fixing hole 510 on the single connection part 50 is designed to include at least one round hole and one waist-shaped hole, wherein the round hole is used to realize the positioning of the support rod 40, and the length direction of the waist-shaped hole is parallel to the length direction of the support rod 40, so that the support rod 40 has a certain position error adjustment range, thereby reducing the difficulty of installing the support rod 40.

[0044] Considering that in different regions and water surface conditions, photovoltaic modules require different tilt angles to achieve the maximum light absorption effect, the bracket module provided by the present disclosure can achieve different heights of bending by processing the bending portion 430 into different bending angles, thereby achieving the tilt requirements of photovoltaic modules under different use conditions. In order to adapt to the tilt requirements of seasonal light, reduce the cost of material replacement, and avoid the high failure risk of the rotating structure design under water surface environment, such as Figure 3As shown, the support rod 40 provided by the present disclosure is designed as a segmented structure, which specifically includes a first support part 450 and a second support part 460, wherein the first support part 450 is a standardized straight profile, that is, a straight tube beam structure, which is simple to produce and has reliable strength, and can be conveniently cut and processed to any length, which is convenient for procurement and replacement; and at the same time, the first support part 450 is fixedly connected to the second support part 460, and the bending part 430 is all arranged on the second support part 460. The above-mentioned design structure enables the first support part 450 to adapt to the second support part 460 with different bending heights, thereby improving the adaptability and flexibility of the bracket module. The connection area between the second support part 460 and the first support part 450 avoids the bending part 430, and such a layout helps to reduce the use of materials while maintaining the integrity and stability of the structure. For a single bracket module, a plurality of second support parts 460 can be provided for a single first support part 450, so that the corresponding second support part 460 can be selected for installation according to the actual application conditions to meet the effective support effect of the photovoltaic panel. It should be noted that the split structure enables the first support portion 450 to be connected to the second support portion 460 with different bending heights, so as to realize different angle settings of the first support portion 450 with the horizontal plane, and usually needs to meet the requirement of the first support portion 450 and the horizontal plane being an angle change of 0°-15°. In the present disclosure, considering the common working conditions of the bracket module, it is preferred that the first support portion 450 has five matching second support portions 460, each of which has a different lifting height and bending angle, so that after being installed with the first support portion 450, the first support portion 450 has an angle of 5°, 8°, 10°, 12° and 15° with the horizontal plane.

[0045] Furthermore, in an environment where the photovoltaic module area is large, or a single bracket module needs to support multiple photovoltaic modules, in order to improve the support stability of the bracket module, such as Figure 4 As shown, the support module further includes a third float 30, which is disposed between the first float 10 and the second float 20 in the length direction of the support rod 40, and is fixedly connected to the support rod 40 through an auxiliary support 310 to provide an additional middle support point structure for the support rod 40. This structure can effectively increase the stability and carrying capacity of the support module, especially in an environment with strong wind or turbulent water flow, the addition of the third float 30 can provide additional support and reduce the displacement or damage of the photovoltaic module caused by environmental factors.

[0046] In addition, considering that the bending portion 430 on the support rod 40 is prone to stress concentration under complex working conditions, a reinforcement member 470 is specially designed at the bending portion 430 on the support rod 40 in the present disclosure to strengthen the structure of the bending portion 430. The reinforcement member 470 can be a square tube or a round tube, and its two ends can contact the positions on both sides of the highest point of the bending portion 430 respectively to form a triangular structure with the bending portion 430; and for the convenience of connection, the reinforcement member 470 can also be a plate structure, which is attached to the bending portion 430 from the side wall direction and locked by fasteners to form a triangular structure. The setting of the reinforcement member 470 can form a stable triangular support structure at the bending portion 430, and its installation structure is simple, which not only enhances the load-bearing capacity of the bending portion 430, but also improves the wind and wave resistance performance of the entire support module.

[0047] Furthermore, in order to improve the stability of the photovoltaic assembly, at least two parallel and spaced support rods 40 are provided in a single support module to support the photovoltaic panel, and preferably the symmetry lines of the two support rods 40 are arranged to coincide with a symmetry line of the first floating body 10 itself, so that the first floating body 10 and the second floating body 20 can provide a more uniform support force distribution for the support rods 40, while reducing the load of a single support rod 40, and improving the stability and durability of the entire support module. The parallel arrangement of multiple support rods 40 also helps to improve the installation efficiency of photovoltaic assemblies, that is, a single support module can carry multiple photovoltaic assemblies, thereby speeding up the construction progress.

[0048] Furthermore, if Fig.11 As shown, the present disclosure also provides a water surface photovoltaic power station, which includes a plurality of bracket modules 610 as provided in the aforementioned embodiments, and a photovoltaic component 620 is fixedly arranged on each bracket module 610. A plurality of bracket modules 610 are arranged in an array to maximize the use of the water surface space and improve the power generation efficiency of the photovoltaic power station; and in the array structure, adjacent bracket modules 610 can also be fixed by connectors of the same specification to improve the structural stability of the entire water surface photovoltaic power station. By rationally planning the layout and spacing of the bracket modules 610, it can be ensured that the illumination between the photovoltaic components 620 does not interfere with each other, while reducing the impact on the ecological environment of the water surface. It should be noted that since the bracket module 610 has the technical effects provided by any of the above embodiments, the water surface photovoltaic power station also has the above technical effects, which will not be repeated herein.

[0049] On the basis of the above embodiments, Figure 8 and Fig. 9As shown, the photovoltaic module 620 can be directly fastened to the mounting hole 440 on the support rod 40 by bolts, which can be fastened by bolts or the like through the opening of the frame of the photovoltaic module 620, and the disassembly and assembly process is convenient and stable. Similarly, if it is necessary to maintain the integrity of the frame of the photovoltaic module 620, such as Fig.10 As shown, a pressure block 480 can also be fixed to the mounting hole 440 by bolts. The pressure block 480 is preferably set as a Z-shaped structure, one wall of which is arranged in contact with the support rod 40 and fixed to the mounting hole 440, and is raised to the height of the frame of the photovoltaic component 620 through a wall connected thereto, and then another wall is used to avoid pressing and limit the frame of the photovoltaic component 620, so as to achieve the fixed setting of the photovoltaic component 620. The above two different fixing methods can select the most suitable method according to the actual installation conditions and requirements. The direct fastening method is simple and fast, suitable for quick installation and maintenance; while the pressure block 480 method provides additional stability and protection, and does not require holes to be opened on the frame structure of the photovoltaic component 620, thereby maintaining the structural integrity of the photovoltaic component 620, and making the installation and maintenance of the water surface photovoltaic power station more flexible and efficient.
