Description

Technical Field

[0001] This utility model relates to the field of water surface photovoltaic equipment technology, and in particular to a support module and a water surface photovoltaic power station. Background Technology

[0002] Floating photovoltaic (PV) power stations are increasingly widely used due to their applicability to various scenarios, including drinking water reservoirs, hydropower station reservoirs, nearshore waters, and extremely cold regions, as well as their safe and environmentally friendly application. Currently, most floating PV power stations use a combination of floating bodies connected sequentially, or floating bodies with supporting struts as the basic load-bearing structure, with PV modules mounted on top for power generation. The PV modules are typically supported by C-shaped struts for easy connection and fixation to other components. However, this type of strut support structure has poor stiffness in the open direction and cannot be bent. For PV modules with specific angle requirements, additional struts are needed, resulting in complex assembly structures, numerous connectors, and a tendency for connections to fail in humid environments, leading to economic losses.

[0003] Therefore, how to improve the stability and versatility of floating photovoltaic modules is a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a support module to improve the stability and versatility of the installation of water surface photovoltaic modules.

[0005] Another objective of this invention is to provide a water surface photovoltaic power station that includes the aforementioned support module.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] In a first aspect, this utility model provides a support module, including a first float, a second float, and a support rod. The first end of the support rod is fixed to the first float, and the second end is fixed to the second float. The support rod is a pipe or plate and includes a continuous bent portion. The vertical height of the bent portion is higher than the first end and the second end, and the bent portion is located close to the first end. A plurality of mounting holes are provided in the area between the bent portion and the second end for fixing photovoltaic modules.

[0008] Preferably, in the above-mentioned support module, both the first float and the second float are provided with connecting parts, and each connecting part has at least two fixing holes spaced apart. One end of the support rod is fixed to the connecting part by two locking members.

[0009] Preferably, in the above-mentioned bracket module, the support rod includes a first support part and a second support part. The first support part is a standardized straight profile and is fixedly connected to the second support part. The bending part is provided on the second support part, and the connection area between the second support part and the first support part avoids the bending part, so that the first support part can be adapted to the second support part with different bending heights.

[0010] Preferably, the above-mentioned support module further includes a third float, which is disposed between the first float and the second float and is fixedly connected to the support rod by an auxiliary bracket.

[0011] Preferably, in the above-mentioned support module, the bending portion is provided with a reinforcing member, which is a tube or plate to form a triangular structure with a portion of the bending portion.

[0012] Preferably, the above-mentioned support module includes at least two parallel and spaced-apart support rods.

[0013] Preferably, in the above-mentioned bracket module, on a single connecting part, at least one of the fixing holes is a round hole, and at least one of the fixing holes is an oblong hole.

[0014] Preferably, in the above-described bracket module, the connecting part is a flat plate and is fixedly attached to one end of the support rod, or...

[0015] The connecting part is a U-shaped plate, and one end of the support rod is embedded in the groove of the U-shaped plate and fixed to the U-shaped plate;

[0016] The connecting part is disposed on one side of the surface of the float or around the float.

[0017] Secondly, this utility model provides a water surface photovoltaic power station, including multiple support modules as described in any of the above embodiments, each of the support modules being fixedly equipped with a photovoltaic module, and the multiple support modules being arranged in an array.

[0018] Preferably, in the above-mentioned water surface photovoltaic power station, the photovoltaic module is directly fastened to the mounting hole by bolts, or a pressure block is fixed to the mounting hole by bolts, and the edge of the photovoltaic module is pressed and locked by the pressure block and the support rod.

[0019] As can be seen from the above technical solution, the bracket module provided by this utility model forms a stable structure through the arrangement of the first float, the second float, and the support rod. This structure can withstand the weight of the photovoltaic module and the influence of environmental factors. Furthermore, the tube or plate design of the support rod allows the bending part to be produced through an integral molding structure, resulting in a continuous molding state. This provides more stable structural strength and avoids the problem of high failure risk in a water environment due to an excessive number of parts or too many gaps in the parts. Depending on the lighting conditions of the application scenario, support rods with different bending angles and lifting heights can be easily produced through bending processes, allowing the photovoltaic module to adapt to different installation environments and conditions, thus increasing flexibility.

[0034] The core of this utility model lies in disclosing a support module to improve the stability and versatility of the installation of water surface photovoltaic modules.

[0035] Another core aspect of this invention is to provide a water surface photovoltaic power station that includes the aforementioned support module.

[0036] To enable those skilled in the art to better understand the present invention, embodiments of the present invention will be described below with reference to the accompanying drawings. Furthermore, the embodiments shown below do not limit the scope of the invention as described in the claims. Additionally, the complete contents of the configurations shown in the following embodiments are not limited to those necessary for the solution of the invention as described in the claims.

[0037] like Figure 1 and Figure 2 As shown, the support module provided in this disclosure is mainly used to support photovoltaic modules on the water surface to meet the power generation requirements of the photovoltaic modules. The support module mainly includes a first float 10, a second float 20, and a support rod 40. The first float 10 and the second float 20 are arranged alternately. They are usually made of high-density polyethylene (HDPE) as the main material, so that the float structure has characteristics such as low density, corrosion resistance, resistance to environmental stress cracking (wind and waves, frost heave environment), resistance to water vapor permeability, UV resistance, and no pollution to the water environment. The first float 10 and the second float 20 can provide an effective support structure through buoyancy. 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 float 10, and its second end 420 is fixedly connected to the second float 20, so that the first float 10 and the second float 20 are connected into an integral structure, and the support rod 40 provides a structural foundation for the photovoltaic modules.

[0038] Specifically, in the support module provided in this disclosure, the support rod 40 is a tubular or plate-shaped component and includes a continuous bent portion 430. It should be noted that the tubular component can be a commonly used rectangular or round tube, and setting the support rod 40 as a tubular or plate-shaped component allows for the creation of the bent portion 430 through a bending structure. The two ends of the bent portion 430 are integrally connected to other areas without creating a seam structure, resulting in higher strength and preventing impurities from causing splicing seams that could affect the structural strength of the support rod 40. Furthermore, the vertical height of the bent portion 430 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 placed on the water surface. Compared to the currently commonly used C-channel steel structure, square, round, or plate-shaped components can integrally process the bent portion 430 through a bending process, providing an inclined support surface for the photovoltaic module without requiring the splicing and fixing of multiple beam structures to achieve an inclined support surface. It should be noted that in this embodiment, the support rod 40 is preferably a square tube structure. The square tube structure is a closed rectangle in its circumferential direction, exhibiting good rigidity in the direction perpendicular to either side wall. This allows it to maintain support for the photovoltaic module in complex water environments. Compared to a C-channel steel structure with openings in its circumferential direction, it improves the structural stability of the support module. The continuous bending portion 430 specifically refers to the area on the support rod 40 where the bending portion 430 is located, which is a non-spliced ​​structure. C-channel steel structures cannot be integrally formed through bending processes. When it is necessary to provide inclined support for the photovoltaic module, it needs to be spliced ​​with other structures to raise the photovoltaic module. Spliced ​​structures have gaps and increase the number of connectors. In the relatively humid environment of the water surface, they are prone to corrosion and connection problems, which can lead to the photovoltaic module collapsing the support structure. This disclosure, by processing the bending portion 430 into a non-spliced ​​structure through an integral bending method, reduces the number of connectors and the splicing gaps in the bending area, thereby improving the support stability of the support module for the photovoltaic module.

[0039] Furthermore, to improve the utilization efficiency of the support rod 40, the bent portion 430 on the support rod 40 is positioned near the first end 410 of the support rod 40. This means the support rod 40 is raised from a position near the first end 410, and the area between the bent portion 430 and the second end 420 is used to mount the photovoltaic module. This allows the photovoltaic module to maintain an inclined state, increasing the light-receiving area of ​​the photovoltaic module and reducing its footprint on the water surface. Simultaneously, multiple mounting holes 440 are provided in the area between the bent portion 430 and the second end 420 to ensure a stable connection for the photovoltaic module. The aforementioned structure, through the arrangement of the first float 10, the second float 20, and the support rod 40, forms a stable structure capable of withstanding the weight of the photovoltaic module and the impact of environmental factors. Furthermore, the design of the tube or plate components of the support rod 40, as well as the continuous state of the bending section 430, provides more stable structural strength and avoids the problem of high failure risk in a water surface environment due to an excessive number of components. Depending on the lighting conditions of the application scenario, support rods 40 with different bending angles and lifting heights can be easily produced through bending processes, enabling the photovoltaic module to adapt to different installation environments and conditions and increasing flexibility.

[0040] Furthermore, in order to improve the fixed connection effect of the support rod 40 on the first float 10 and the second float 20, and to provide a stable support structure for the photovoltaic module, in this disclosure, both the first float 10 and the second float 20 are provided with a connecting part 50. The connecting part 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 forms a surface contact by mating with the connecting part 50, and at least two connectors are used on the surface contact structure to lock the connection into an integral structure.

[0041] Specifically, each connecting part 50 has at least two connecting holes spaced apart for fixing the end of the support rod 40. For the connecting part 50, such as Figure 6 and Figure 7 As shown, when it is a flat plate structure, it can be set on the top surface of the float in the vertical direction, making the docking and fixing of the support rod 40 simpler; while when it is a U-shaped plate structure, its bottom is set against the top surface of the float in the vertical direction, with the opening facing upward. At this time, one end of the support rod 40 is embedded in the groove structure of the U-shaped plate and contacts all three inner wall surfaces of the U-shaped plate, thus achieving a larger area of ​​contact. 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 improve the stability of the end connection structure of the support rod 40.

[0042] Furthermore, regarding the extended area of ​​the connecting part 50, the connecting part 50 can be provided only in a portion of the upper wall of the float, only needing to satisfy the installation space at the end of the support rod 40. In this disclosure, the connecting part 50 surrounds the float, that is, the connecting part 50 is ring-shaped and fixed to the circumferential outer wall of the float, so that the connecting part 50 and the float 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 of the float, which can also reduce the installation difficulty of the support rod 40 and provide a flexible installation method.

[0043] In the above structure, such as Figure 5 As shown, at least two fixing holes 510 are spaced apart on each individual connecting part 50 to secure the end of the support rod 40, ensuring the connection effect of the support rod 40. Simultaneously, while meeting the strength support requirements, the end of the support rod 40 can also extend the distance between the two floats through the empty fixing holes 510, thus achieving the same support effect and allowing for greater flexibility and adjustability of the support module during installation. It should be noted that the fixing holes 510 on each individual connecting part 50 are designed to include at least one round hole and one oblong hole. The round hole is used for positioning the support rod 40, while the length direction of the oblong hole is parallel to the length direction of the support rod 40, allowing for a certain range of positional error adjustment and reducing the installation difficulty of the support rod 40.

[0044] Considering that photovoltaic modules require different tilt angles to achieve maximum light absorption in different regions and under different water surface conditions, the support module provided in this disclosure can be processed with the bending portion 430 to achieve different bending heights, thereby meeting the tilt requirements of photovoltaic modules under different operating conditions. Furthermore, to adapt to seasonal light intensity tilt requirements, reduce material replacement costs, and avoid the high failure risk of rotating structures in water surface environments, such as... Figure 3As shown, the support rod 40 provided in this disclosure is designed as a segmented structure, specifically including a first support part 450 and a second support part 460. The first support part 450 is a standardized straight profile, i.e., a straight tube beam structure, which is simple to manufacture and has reliable strength. It can also be easily cut to any length, facilitating procurement and replacement. Simultaneously, the first support part 450 is fixedly connected to the second support part 460, while the bending portions 430 are all located on the second support part 460. This design structure allows the first support part 450 to adapt to second support parts 460 with different bending heights, thereby improving the adaptability and flexibility of the support module. The connection area between the second support part 460 and the first support part 450 avoids the bending portions 430; this layout helps reduce material usage while maintaining structural integrity and stability. For a single support module, multiple second support parts 460 can be provided for a single first support part 450, allowing for the selection of the appropriate second support part 460 for installation according to actual application conditions to achieve effective support for the photovoltaic panels. It should be noted that the split structure allows the first support portion 450 to connect with second support portions 460 at different bending heights, thereby achieving different angle settings between the first support portion 450 and the horizontal plane. Typically, this requires the first support portion 450 to have an angle variation of 0°-15° with the horizontal plane. Considering the common operating conditions of the bracket module in this disclosure, it is preferable that the first support portion 450 has five corresponding second support portions 460, each with a different lifting height and bending angle, so that after installation with the first support portion 450, the first support portion 450 can have angles of 5°, 8°, 10°, 12°, and 15° with the horizontal plane.

[0045] Furthermore, in environments with large photovoltaic module areas, or where a single support module needs to support multiple photovoltaic modules, in order to improve the support stability of the support module, such as... Figure 4 As shown, the support module also includes a third float 30, which is positioned between the first float 10 and the second float 20 along the length of the support rod 40. The third float 30 is fixedly connected to the support rod 40 via an auxiliary bracket 310, providing an additional central support point structure for the support rod 40. This structure effectively increases the stability and load-bearing capacity of the support module. Especially in environments with strong winds or rapid currents, the addition of the third float 30 provides extra support, reducing displacement or damage to the photovoltaic modules caused by environmental factors.

[0046] Furthermore, considering the potential for stress concentration at the bend 430 on the support rod 40 under complex working conditions, a reinforcing member 470 is specifically designed at the bend 430 in this disclosure to structurally strengthen the bend 430. The reinforcing member 470 can be a square or round tube, with both ends contacting the sides of the highest point of the bend 430 to form a triangular structure. For ease of connection, the reinforcing member 470 can also be a plate structure, fitting snugly against the bend 430 from the sidewall direction and locked in place with fasteners to form a triangular structure. The reinforcing member 470 creates a stable triangular support structure at the bend 430, with a simple installation structure. This not only enhances the load-bearing capacity of the bend 430 but also improves the overall support module's resistance to wind and waves.

[0047] Furthermore, to improve the stability of the photovoltaic modules, at least two parallel and spaced support rods 40 are provided in each support module to support the photovoltaic panels. Preferably, the lines of symmetry of the two support rods 40 coincide with a line of symmetry of the first float 10 itself, so that the first float 10 and the second float 20 can provide a more uniform distribution of support force to the support rods 40, while reducing the load on individual support rods 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 the photovoltaic modules, that is, a single support module can support multiple photovoltaic modules, thereby accelerating the construction progress.

[0048] Furthermore, such as Figure 11 As shown, this disclosure also provides a floating photovoltaic power station, which includes multiple support modules 610 as provided in the foregoing embodiments, and each support module 610 is fixedly equipped with a photovoltaic module 620. The multiple support modules 610 are arranged in an array to maximize the use of water surface space and improve the power generation efficiency of the photovoltaic power station. Furthermore, in the array structure, adjacent support modules 610 can be fixed using connectors of the same specifications to enhance the structural stability of the entire floating photovoltaic power station. By rationally planning the layout and spacing of the support modules 610, it can be ensured that the illumination of the photovoltaic modules 620 does not interfere with each other, while reducing the impact on the aquatic ecological environment. It should be noted that since the support module 610 has the technical effects provided in any of the above embodiments, the floating photovoltaic power station also possesses the above technical effects, which will not be elaborated upon here.

[0049] Based on the above embodiments, such as Figure 8 and Figure 9As shown, the photovoltaic module 620 can be directly fastened to the mounting hole 440 on the support rod 40 with bolts. This is achieved through openings in the frame of the photovoltaic module 620 and locking with bolts, making the assembly and disassembly process convenient and highly stable. Similarly, if it is necessary to maintain the integrity of the photovoltaic module 620 frame structure, such as... Figure 10 As shown, a pressure block 480 can also be fixed to the mounting hole 440 with bolts. The pressure block 480 is preferably configured as a Z-shaped structure, with one wall surface conforming to the support rod 40 and fixed to the mounting hole 440. Another wall surface connected to it is raised to the height of the photovoltaic module 620 frame, while the other prevents compression and limits the photovoltaic module 620 frame, thus achieving a fixed installation of the photovoltaic module 620. The two different fixing methods can be selected based on the actual installation conditions and requirements. Direct fastening is simple and quick, suitable for rapid installation and maintenance; while the pressure block 480 method provides additional stability and protection, and eliminates the need for drilling holes in the photovoltaic module 620 frame structure, maintaining the structural integrity of the photovoltaic module 620, making the installation and maintenance of the floating photovoltaic power station more flexible and efficient.
