Description

Technical Field

[0001] This utility model relates to the field of photovoltaic installation structure technology, specifically a fixed component for waterborne photovoltaic installation. Background Technology

[0002] In recent years, floating photovoltaic power generation, as a new type of clean energy that efficiently utilizes water surface resources, has been widely applied in reservoirs, lakes, and fishery-solar hybrid projects. Existing floating photovoltaic platforms typically employ single-piece buoyancy structures or rigid column support structures, usually consisting of a floating body or fixed piles directly connected to the upper support structure, achieving support through buoyancy on the water surface or by relying on underwater fixed piles.

[0003] However, this type of structure has several shortcomings in practical applications. First, single-piece buoyancy structures rely on bolts or sleeves for fixing during modular assembly, lacking a flexible rotating assembly mechanism. This makes it difficult to adjust the angle according to different water shapes and photovoltaic array layouts, resulting in insufficient installation flexibility. Second, while rigid column support structures can fix the position, construction requires underwater piling, which is costly, time-consuming, and difficult to implement in deep water or soft soil areas.

[0004] Regarding wind and wave resistance and attitude stability, existing single-piece buoyancy structures mostly rely on the buoyancy provided by the buoy itself, without combining it with a counterweight structure for stability control. This makes them prone to significant swaying during wind, waves, or load changes, affecting the power generation efficiency and lifespan of the photovoltaic modules. Furthermore, existing splicing and locking methods mostly use external threads or snap-fit ​​connections, which are cumbersome and time-consuming to install. In long-term humid and high-salt-spray environments, they are prone to corrosion or jamming, increasing maintenance costs and disassembly difficulty.

[0005] In summary, existing floating photovoltaic installation platforms are inadequate in terms of assembly flexibility, connection stability, wind and wave resistance, and ease of operation and maintenance. There is an urgent need for a floating photovoltaic installation fixing component that can achieve modular and flexible splicing, reliable connection, stable buoyancy, and adaptability to complex water areas. Utility Model Content

[0006] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0007] Therefore, the technical solution adopted by this utility model is as follows: a waterborne photovoltaic installation and fixing component, including a fixing plate assembly, a floating base, and fasteners. Through the coordinated cooperation of these three components, rapid deployment, stable locking, and long-term stable operation of the waterborne photovoltaic array are achieved. The fixing plate assembly adopts a modular splicing structure, the floating base provides buoyancy support and attitude stability control, and the fasteners enable rapid expansion and locking at the splicing points, thereby improving overall installation efficiency and operational safety. The fixing plate assembly includes a positioning plate and several lug plates set on the bottom surface of the positioning plate. Several grooves are opened on the bottom surface of the positioning plate, and an installation hole is opened in the middle of the positioning plate. The edges of the lug plates are provided with latches for engaging with adjacent fixing plate assemblies. This structure enables multiple positioning plates to form a stable splicing array on the water surface and provides a centrally located installation hole for the floating base, thereby improving the overall support strength and assembly stability of the platform. The floating base is sleeved inside the installation hole of the fixing plate assembly. A conical block is detachably installed inside the floating base, and a screw is threaded through the bottom of the conical block for connecting to the bottom end of the photovoltaic support. This mating structure not only ensures the limiting connection between the float and the positioning plate, but also stably transfers the load of the photovoltaic bracket to the float, and uses buoyancy to support and stabilize the photovoltaic module.

[0008] In a preferred embodiment, the fastener includes an expansion buckle and an expansion cone that mates with the expansion buckle. The expansion buckle has several lugs on its outer periphery and several deformation gaps spaced apart on its surface. When the expansion cone is inserted into the expansion buckle, the lugs undergo radial outward deformation at the deformation gaps, thereby forming an expansion lock with the surfaces of the positioning plate and the lug plate. This structure can quickly complete the mechanical locking at the joint and remain stable under wind, waves, and loads, while also facilitating disassembly and maintenance.

[0009] In a preferred example, the positioning plate is a regular polygonal structure, and the lug plates are installed on the bottom surface of the positioning plate by rotation. The number of lug plates is half the number of slots, and adjacent positioning plates are spliced ​​together by the engagement of the lug plates and slots. This structure enables rapid connection at different arrangement angles, giving the floating photovoltaic platform greater flexibility and adaptability during installation.

[0010] In a preferred example, both the groove and the lug plate have holes on their surfaces that mate with fasteners. After the lug plate and the groove are engaged, they are locked by fasteners to achieve axial clamping and radial limiting at the joint, ensuring the stability of the platform under wave impact, wind load and maintenance load.

[0011] In a preferred embodiment, the float is made of high-density polyethylene and the positioning plate is made of corrosion-resistant aluminum alloy to improve corrosion resistance in high humidity and high salt spray environments. The counterweight ring of the float is a ring-shaped metal part that is embedded in the bottom surface of the inner cavity of the float, which can effectively suppress the swaying under the action of wind and waves and significantly improve the attitude stability and anti-overturning ability of the platform when it is running on the water surface.

[0012] In a preferred example, the outer diameter of the cone gradually increases from top to bottom to match the conical structure of the inner cavity of the float, thereby limiting and positioning the photovoltaic bracket and preventing loosening under external force; the screw is used to reliably connect with the bottom end of the photovoltaic bracket to ensure the stability and pull-out resistance of the bracket during operation.

[0013] In a preferred example, the lugs of the expansion buckle are evenly distributed along the circumferential direction, and the deformation gap formed between each lug expands radially outward when the expansion cone is inserted, thereby forming a continuous clamping and locking force between the lug plate and the positioning plate, so that the connection reliability of the splice is maintained during long-term operation of the platform.

[0014] In a preferred embodiment, the fixing plate assembly is an array of multiple positioning plates arranged to form a support platform adapted for photovoltaic module installation. Combined with the buoyancy support of the floating base and the locking effect of the fasteners, the entire platform can be stably laid, operated, and maintained in a water surface environment, significantly improving the construction efficiency and operational safety of the floating photovoltaic system. The beneficial effects achieved by this utility model are as follows:

[0015] 1. In this utility model, a photovoltaic installation platform structure that can be quickly assembled and securely locked on the water surface is constructed through the coordinated cooperation of fixed plate assemblies, floats, and fasteners. The fixed plate assemblies adopt a modular splicing method using regular polygonal positioning plates and rotatable lug plates. The array arrangement is achieved through the cooperation of grooves and fasteners, which not only ensures the flexibility of installation but also improves the reliability of structural connections. The cooperation of the floats, cones, and screws ensures a stable connection between the photovoltaic bracket and the platform. The setting of the counterweight ring significantly improves the resistance to wind and waves and the anti-overturning ability, ensuring the attitude stability of the platform during long-term operation on the water surface.

[0016] 2. In this utility model, the float is made of high-density polyethylene and the positioning plate is made of corrosion-resistant aluminum alloy, which combines lightweight and high corrosion resistance, can adapt to the harsh environment of high humidity and high salt spray on the water surface, extend the overall service life and reduce operation and maintenance costs.

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0027] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0028] The following describes, with reference to the accompanying drawings, some embodiments of a waterborne photovoltaic installation and fixing component provided by this utility model.

[0029] Combination Figures 1-5 As shown, the present invention provides a waterborne photovoltaic installation and fixing component, including a fixing plate assembly 100, a floating base 200, and fasteners 300.

[0030] In this embodiment, the fixing plate assembly 100 includes a positioning plate 110 and a plurality of lug plates 120 disposed on the bottom surface of the positioning plate 110. The bottom surface of the positioning plate 110 has a plurality of grooves 111, and the center of the positioning plate 110 has a mounting hole. The edges of the lug plates 120 are provided with latches 121 for engaging with adjacent fixing plate assemblies 100. The lug plates 120 can be housed within the grooves 111. Through this structural design, multiple fixing plate assemblies 100 can be stably spliced ​​on a water surface platform, and a central mounting hole support is provided for the installation of the float 200.

[0031] The float 200 is fitted inside the mounting hole of the fixed plate assembly 100. A cone block 210 is detachably installed inside the float 200, and a screw 220 is provided through the bottom of the cone block 210. The screw 220 is used to connect to the bottom end of the photovoltaic bracket, thereby firmly installing the photovoltaic bracket above the float 200. This structure ensures that the float 200 can bear the weight of the photovoltaic module and maintain stable buoyancy on the water surface.

[0032] The fastener 300 includes an expansion buckle 310 and an expansion cone 320 that cooperates with the expansion buckle 310. The expansion buckle 310 has a plurality of lugs 311 on its outer periphery, and a plurality of deformation gaps 312 are spaced apart on its surface. When the expansion cone 320 is inserted into the expansion buckle 310, the lugs 311 undergo radial outward deformation at the deformation gaps 312, thereby achieving expansion and locking with the surfaces of the fixing plate assembly 100 and the ear plate 120, effectively preventing the ear plate 120 from loosening from the groove 111 during use.

[0033] In this embodiment, the positioning plate 110 is preferably a regular polygonal structure, and its bottom ear plate 120 is installed by rotation, and the number of ear plates 120 is half the number of slots 111. Adjacent positioning plates 110 are spliced ​​by inserting the ear plates 120 into the slots 111 of adjacent plate groups and fastening them together, so that multiple positioning plates 110 can be combined into a large-area platform in a stable array, which is convenient for large-scale deployment of photovoltaic modules on the water surface.

[0034] Furthermore, the surfaces of the groove 111 and the ear plate 120 are provided with holes for engaging with the fastener 300. After the ear plate 120 and the groove 111 are fastened together, the fastener 300 is used to lock them in place, so that the ear plate 120 and the positioning plate 110 remain stably connected when subjected to external forces, thereby improving the resistance to wind and waves and vibration.

[0035] In this embodiment, the float 200 is made of high-density polyethylene to ensure good water resistance, impact resistance and corrosion resistance during long-term use on the water surface; the positioning plate 110 is made of corrosion-resistant aluminum alloy to maintain structural strength and stability in high humidity and high salt spray environments on the water surface; the float 200 has an embedded annular metal counterweight ring 230, which is located on the bottom surface of the inner cavity of the float 200, and can suppress excessive swaying of the float 200 in the case of large waves, thereby improving the stability of the photovoltaic module when operating on the water surface.

[0036] In this embodiment, the outer diameter of the cone block 210 gradually increases from top to bottom to match the conical structure of the inner cavity of the float 200. This ensures that the cone block 210 can reliably limit the connection with the float 200 after installation, preventing the photovoltaic support connection from loosening due to external forces. Simultaneously, the screw 220 penetrating the bottom of the cone block 210 securely connects the bottom end of the photovoltaic support to the float 200, ensuring stable connection even under conditions of wind, waves, and water flow impact.

[0037] In this embodiment, the lugs 311 of the expansion buckle 310 are evenly distributed along its circumference. The deformation gap 312 formed between each lug 311 undergoes radial outward deformation when the expansion cone 320 is inserted, thereby generating a radial clamping force on the surfaces of the mating lug plate 120 and the positioning plate 110, achieving a tight lock. This structure is not only quick to install, but also easy to disassemble; simply pull out the expansion cone 320 to release the lock, facilitating maintenance and replacement.

[0038] In this embodiment, the fixing plate assembly 100 is an array of multiple interconnected positioning plates 110. The engagement of the lug plate 120 and the groove 111 forms a continuous support platform, capable of adapting to the large-area installation requirements of photovoltaic modules. After installation, the float 200 is located at the mounting hole position of the fixing plate assembly 100, providing buoyancy support for the photovoltaic bracket, while the fastener 300 ensures a firm and reliable connection between modules.

[0039] In summary, when using this utility model, multiple fixing plate groups 100 are first assembled into the required array structure. Then, the float 200 is fitted into the mounting holes, and the cone block 210 and screw 220 are installed to connect the photovoltaic bracket. Finally, the fastener 300 is used to lock the ear plate 120 and the groove 111, thus achieving stable installation of the photovoltaic bracket on the water surface. This structure has the advantages of quick installation, reliable connection, strong corrosion resistance, and high resistance to wind and waves.

[0040] Working principle and usage process of this utility model:

[0041] In this embodiment, the waterborne photovoltaic installation and fixing component of this utility model achieves stable support and rapid installation of photovoltaic modules on the water surface platform through the coordinated cooperation of the fixing plate group 100, the floating seat 200 and the fastener 300.

[0042] During use, multiple fixed plate assemblies 100 are first laid out according to the designed array. The positioning plates 110 are interlocked with the grooves 111 on adjacent positioning plates 110 via bottom lug plates 120. The latches 121 are inserted into the grooves 111 of adjacent positioning plates 110, achieving modular splicing and forming a continuous support platform. Through this combination of regular polygonal structure and rotating lug plates 120, the splicing angle and arrangement of the plate assemblies can be flexibly adjusted according to the installation environment. Unused lug plates 120 of the edge positioning plates 110 can be stored in the grooves 111.

[0043] Secondly, a float 200 is fitted into the mounting hole in the middle of the positioning plate 110. The float 200 is made of high-density polyethylene, and a metal counterweight ring 230 is embedded in the bottom of its inner cavity, which can provide buoyancy on the water surface and enhance stability against wind and waves. During installation, the cone block 210 is placed into the inner cavity of the float 200, so that its outer diameter fits tightly with the conical surface of the inner cavity of the float, and the screw 220 penetrating the bottom of the cone block 210 extends out of the bottom surface of the positioning plate 110, which facilitates connection and fixation to the bottom end of the photovoltaic bracket.

[0044] Next, the fastener 300 is used to achieve overall locking, forming a strong expansion locking force on the surfaces of the lug plate 120 and the positioning plate 110 to prevent the plate assembly from loosening.

[0045] Finally, the bottom of the photovoltaic module support is connected to the float 200 and positioning plate 110 via screws 220. Photovoltaic panels are then installed on top of the support, realizing the deployment of the water surface photovoltaic power generation unit. After installation, this structure can operate stably in the water environment for a long time. The float 200 provides buoyancy support, the counterweight ring 230 suppresses swaying caused by wind and waves, and the fasteners 300 ensure the tight connection of each module, thereby effectively improving the operational stability and maintenance convenience of the photovoltaic array on water.
