Description

Technical Field

[0001] This invention relates to the field of marine photovoltaic technology, and specifically to a bracket and installation method suitable for marine photovoltaic installation. Background Technology

[0002] Offshore photovoltaics refers to the installation of photovoltaic panels on the surface of a platform on water, and this technology has attracted widespread attention.

[0003] Lightweight design and platform stability are crucial for the development of sustainable energy. Firstly, lightweight design reduces the platform's load, lowering material costs and construction complexity. Secondly, platform stability ensures reliable system operation in harsh weather and complex aquatic environments, reducing damage and safety risks caused by external forces such as waves and wind. Furthermore, a stable platform allows for better photovoltaic panel layout and adjustment, maximizing the utilization of solar energy resources and improving photovoltaic power generation efficiency.

[0004] The support structure is directly connected and fixed to the photovoltaic modules. The load on each module is transferred to the platform through the support structure. As the medium for load transfer, the photovoltaic support structure is often the weakest point in the overall offshore photovoltaic structure.

[0005] Existing photovoltaic (PV) mounting systems typically use bolts for fastening, which is inefficient and prone to loosening under the influence of wind and waves at sea. This can lead to damage to the PV panels, resulting in low reliability, reduced power generation efficiency, increased maintenance costs, and an inability to meet actual needs. Summary of the Invention

[0006] The purpose of this invention is to provide a support structure and installation method suitable for offshore photovoltaic installations, thereby solving the technical problem of low reliability in photovoltaic panel installation.

[0007] The solution of the present invention to the above-mentioned technical problems is as follows: A support structure suitable for offshore photovoltaic installation includes a supporting float, a fastening mechanism, and multiple supporting slide rails. The multiple supporting slide rails are spaced laterally along the supporting float. Each supporting slide rail has a locking groove along its length on its front side. Two supporting slide rails have locking grooves facing each other, forming a photovoltaic mounting position between them. The back side of each supporting slide rail is a fastening mounting position. The photovoltaic mounting position is used to install photovoltaic panels. The fastening mechanism is located at the fastening mounting position, with its fixed end connected to the supporting float and its telescopic end connected to the corresponding supporting slide rail.

[0008] Furthermore, the number of the fastening mechanisms is multiple, and the multiple fastening mechanisms are spaced apart along the longitudinal direction of the fastening installation position.

[0009] Further specifying, the fastening mechanism includes a fastening support, a retraction motor, a retraction push rod, and a control module, wherein the control module is communicatively connected to the retraction motor; The fixed end of the retraction motor is connected to the support float via a fastening support, and the telescopic end of the retraction motor is connected to the back side of the support slide rail via a retraction push rod, which is perpendicular to the support slide rail.

[0010] Furthermore, the inner wall of the snap-fit ​​groove is provided with a rubber limiting layer.

[0011] Furthermore, the rubber limiting layer is provided with a plurality of serrated blocks arranged sequentially along its length.

[0012] Furthermore, the bracket suitable for offshore photovoltaic installation also includes multiple limiters, which are disposed in the snap-fit ​​groove and cooperate with the serrated block. The multiple limiters are spaced apart along the length direction of the support slide rail, and the interval between two adjacent limiters on the same support slide rail matches the longitudinal length of the photovoltaic panel.

[0013] Further defined, the limiter includes a limit block, a limit drive, and a limit sleeve. There are two limit blocks, which are arranged vertically opposite each other. The limit sleeve is fitted on the outside of the two limit blocks. The limit drive is disposed on the limit sleeve and is connected to the two limit blocks in a transmission manner. The outer end of the limit block matches the gap between two adjacent sawtooth blocks.

[0014] Furthermore, the limit drive and control module are communicatively connected.

[0015] Further defined, the supporting floating plate includes two supporting longitudinal plates and multiple supporting transverse plates. The multiple supporting transverse plates are spaced apart between the two supporting longitudinal plates along the length direction of the supporting longitudinal plates. The spacing between two adjacent supporting transverse plates matches the longitudinal length of the photovoltaic panel. The fastening mechanism is provided on the supporting transverse plates and the supporting longitudinal plates opposite to the supporting transverse plates.

[0016] A method for installing a support structure suitable for offshore photovoltaic installations, based on the aforementioned support structure suitable for offshore photovoltaic installations, includes the following steps: S1. Determine the spacing between adjacent support horizontal plates and the spacing between adjacent support slide rails based on the size of the photovoltaic panel; S2. Slide the photovoltaic panel along the snap-fit ​​groove on the support rail to the installation position; S3. The retraction motor controls the retraction push rod to move the support slide rail laterally, reducing the lateral width of the photovoltaic installation position and clamping the photovoltaic panel. S4. Insert the limiter into the snap-fit ​​groove, so that the limiter is close to both ends of the longitudinal length of the photovoltaic panel. Then, control the limiter block to extend and lock with the rubber limiter layer through the limit drive.

[0017] The beneficial effects of this invention are as follows: 1. This invention features a supporting slide rail on a supporting floating plate, with a snap-fit ​​groove on the slide rail. This allows the photovoltaic panel to slide along the snap-fit ​​groove during installation for easy position adjustment, simplifying the installation process. Simultaneously, a fastening mechanism is provided on the back side of the supporting slide rail. After installation, the width of the photovoltaic installation position can be reduced using the fastening mechanism, clamping the photovoltaic panel laterally to prevent wobbling and movement. This simple and convenient operation improves installation efficiency and meets actual installation needs.

[0018] 2. This invention, by setting a limiter in the snap-fit ​​groove, can limit the photovoltaic panel in the longitudinal direction, further improving the reliability of photovoltaic panel installation and ensuring the service life of the photovoltaic panel; by setting a rubber limiting layer in the snap-fit ​​groove, it can buffer the contact position between the photovoltaic panel and the snap-fit ​​groove, avoiding damage to the photovoltaic panel, while reducing the shaking impact of the photovoltaic panel in the vertical direction, and can cooperate with the limiter to improve the limiting reliability of the limiter, thereby improving both installation efficiency and installation reliability.

[0025] Example 1 refer to Figure 1 and Figure 2 This invention provides a support structure suitable for offshore photovoltaic installation, comprising a support float 10, a fastening mechanism 20, and multiple support slide rails 30. The support float 10 can float on the sea. A single support slide rail 30 is arranged along the longitudinal direction of the support float 10, and multiple support slide rails 30 are spaced apart along the transverse direction of the support float 10. Two support slide rails 30 form a group. A U-shaped snap-fit ​​groove 31 is provided on the front side of the support slide rail 30. The snap-fit ​​groove 31 is arranged in the same direction as the support slide rail 30 and facilitates engagement with the side end of the photovoltaic panel 50. At this time, the snap-fit ​​grooves 31 of the support slide rails 30 in the same group are arranged opposite each other to form a photovoltaic installation position. The support slide rail 30 can slide to connect with the photovoltaic panel 50 through the snap-fit ​​groove 31, which facilitates the installation of the photovoltaic panel 50 at one end of the support slide rail 30 and then sliding the photovoltaic panel 50 to the required installation position, which is convenient for moving and adjusting the position and improves installation efficiency.

[0026] The fastening mechanism 20 is mounted on the back side of the support slide rail 30, which is the fastening mounting position. The fixed end of the fastening mechanism 20 is connected to the support floating plate 10, and the telescopic end of the fastening mechanism 20 is connected to the corresponding support slide rail 30. The telescopic movement of the fastening mechanism 20 can drive the corresponding support slide rail 30 to move in the lateral direction along the support floating plate 10. Thus, during installation, the photovoltaic panel 50 is clamped in the lateral direction by reducing the width of the photovoltaic mounting position. During disassembly, the width of the photovoltaic mounting position is increased to release the clamp on the photovoltaic panel 50 for easy removal.

[0027] There are multiple fastening mechanisms 20. At least two fastening mechanisms 20 are provided on the back side of a single support slide rail 30 to ensure that the two ends of the support slide rail 30 can be subjected to balanced force. Preferably, the number of fastening mechanisms 20 on the back side of a single support slide rail 30 is one more than the number of photovoltaic panels 50 installed. The multiple fastening mechanisms 20 are spaced apart along the longitudinal direction of the fastening installation position. The spacing between two adjacent fastening mechanisms 20 on the same side of the support slide rail 30 matches the length of the photovoltaic panel 50.

[0028] Preferably, the supporting floating plate 10 includes two supporting longitudinal plates 11 and multiple supporting transverse plates 12 to reduce the weight of the supporting floating plate 10; the multiple supporting transverse plates 12 are spaced apart between the two supporting longitudinal plates 11 along the length direction of the supporting longitudinal plates 11, and the spacing between two adjacent supporting transverse plates 12 matches the longitudinal length of the photovoltaic panel 50; the fastening mechanism 20 is provided on the supporting transverse plates 12 and the supporting longitudinal plates 11 opposite to the supporting transverse plates 12.

[0029] refer to Figure 3 To further explain, the fastening mechanism 20 includes a fastening support 21, a retracting motor 22, a retracting push rod 23, and a control module 24. The control module 24 is communicatively connected to the retracting motor 22 and is used to control the extension or retraction of the retracting motor 22. The fixed end of the retracting motor 22 is connected to the support float 10 through the fastening support 21, and the telescopic end of the retracting motor 22 is connected to the back side of the support slide rail 30 through the retracting push rod 23. The retracting push rod 23 is perpendicular to the support slide rail 30. The extension and retraction of the retracting motor 22 can drive the support slide rails 20 in the same group to move in opposite directions or in opposite directions, which facilitates disassembly and assembly and ensures the stable clamping of the photovoltaic panel 50.

[0030] Preferably, in order to improve the service life of the photovoltaic panel 50 and reduce wear, a rubber limiting layer 32 is provided on the inner wall of the snap-fit ​​groove 31. This layer can also uniquely limit and buffer the displacement of the photovoltaic panel 50 in the vertical direction, thereby further protecting the photovoltaic panel 50.

[0031] The rubber limiting layer 32 has multiple serrated blocks arranged sequentially along its length. The serrated blocks and the rubber limiting layer 32 are an integral structure, which reduces the contact area between the photovoltaic panel 50 and the rubber limiting layer 32 and increases the friction between the photovoltaic panel 50 and the rubber limiting layer 32.

[0032] To further explain, the support structure suitable for offshore photovoltaic installation also includes multiple limiters 40. The limiters 40 are set in the snap-fit ​​groove 31 and cooperate with the serrated block. The multiple limiters 40 are all spaced apart along the length direction of the support slide rail 30. The interval between two adjacent limiters 40 on the same support slide rail 30 matches the longitudinal length of the photovoltaic panel 50, which is used to limit the photovoltaic panel 50 in the longitudinal direction and prevent the photovoltaic panel 50 from shaking in the longitudinal direction.

[0033] The upper and lower ends of the limiter 40 are snapped between two adjacent sawtooth blocks to limit the photovoltaic panel 50, which is convenient to operate and reliable in limiting the position.

[0034] refer to Figure 4 Specifically, the limiter 40 includes a limit block 41, a limit drive 42, and a limit sleeve 43. There are two limit blocks 41, which are arranged vertically opposite each other. The outer end of the limit block 41 matches the gap between two adjacent sawtooth blocks. The limit sleeve 43 is sleeved on the outside of the two limit blocks 41, and the limit blocks 41 can slide up and down along the limit sleeve 43. The limit drive 42 is set on the limit sleeve 43 and is connected to the two limit blocks 41. The limit drive 42 can drive the two limit blocks 41 to extend or retract. After the limit blocks 41 extend, they engage with two adjacent sawtooth blocks to limit the photovoltaic panel 50. The limit blocks 41 can be removed after retraction for easy operation.

[0035] The preferred limit drive 42 is connected to the control module 24, and can automatically realize limit and release according to the needs.

[0036] Example 2 Based on the support structure for offshore photovoltaic installation provided in Embodiment 1, this embodiment provides a support structure installation method suitable for offshore photovoltaic installation, including the following steps: S1. Determine the spacing between adjacent support horizontal plates 12 and adjacent support slide rails 30 based on the dimensions of the photovoltaic panel 50. S2. Slide the photovoltaic panel 50 along the snap-fit ​​groove 31 on the support slide rail 30 to the installation position; S3. The retraction motor 22 controls the retraction push rod 23 to push the support slide rail 30 to move laterally, reducing the lateral width of the photovoltaic installation position and clamping the photovoltaic panel 50. S4. Insert the limiter 40 into the snap-fit ​​groove 31, so that the limiter 40 is tightly attached to both ends of the longitudinal length of the photovoltaic panel 50. Then, control the limiter block 41 to extend and snap into the rubber limiter layer 32 through the limiter drive 42.
