Description

Technical Field

[0001] This invention relates to the field of offshore photovoltaic support technology, specifically to an offshore photovoltaic support system and its installation method. Background Technology

[0002] Offshore photovoltaics refers to the installation of photovoltaic panels on the sea surface, which makes full use of the advantages of natural cooling by seawater, unobstructed views, and close proximity to electrical loads to improve power generation performance. This technology has attracted widespread attention.

[0003] Currently, the mainstream method for offshore photovoltaic systems is fixed photovoltaic systems based on pile foundations. This mainly involves fixing the photovoltaic panels to the installation platform using bolts and nuts through drilling and other methods. This requires carrying a lot of tools, making the installation cumbersome and complex, increasing the difficulty of installation and reducing efficiency. Furthermore, at sea, the photovoltaic panels sway due to waves and wind, which can easily cause the connection to loosen and become unstable, thereby damaging the photovoltaic panels, reducing the power generation efficiency of offshore photovoltaic panels, increasing maintenance and repair costs, and failing to meet actual needs. Summary of the Invention

The transverse base is mounted on the support beam. The fixed end of the lateral electromagnetic booster is connected to the transverse base. The telescopic end of the lateral electromagnetic booster faces the transverse side of the photovoltaic installation position and is used to clamp the photovoltaic panel longitudinally. The bottom of the downward support is connected to the transverse base. The fixed end of the downward electromagnetic booster is connected to the downward support. The telescopic end of the downward electromagnetic booster is set along the vertical direction and is used to clamp the photovoltaic panel vertically.

[0009] Further specifying, the lateral clamp also includes a lateral push sensor and a downward pressure sensor. The lateral push sensor is disposed on the telescopic end of the lateral electromagnetic booster, and the downward pressure sensor is disposed on the telescopic end of the downward electromagnetic booster. Both the lateral push sensor and the downward pressure sensor are signal-connected to the lateral electromagnetic controller.

[0010] Further specifying, the lateral clamp also includes a downward pressure energy storage mechanism, the bottom of which is connected to the lateral base, the downward pressure energy storage mechanism is located on one side of the downward pressure support, and the downward pressure energy storage mechanism is located directly below the downward pressure sensor; the side push sensor is slidably connected to the lateral base via a sliding rail.

[0011] Further defined, the longitudinal clamp includes a longitudinal support, a retracting motor, and a pressing buckle. The longitudinal support is located on the top of the longitudinal beam of the bracket. The fixed end of the retracting motor is connected to the top of the longitudinal support. The pressing buckle is connected to the telescopic end of the retracting motor. Photovoltaic slots that mate with the sidewalls of the photovoltaic panel are provided on both the left and right sides of the pressing buckle.

[0012] Furthermore, the longitudinal clamp also includes a retraction sensor, and the pressing buckle is connected to the telescopic end of the retraction motor through the retraction sensor.

[0013] Further specified, the photovoltaic panel is provided with an L-shaped connecting frame on its horizontal side, the short side of the L-shaped connecting frame is perpendicularly connected to the bottom of the photovoltaic panel, and the long side of the L-shaped connecting frame is parallel to the bottom of the photovoltaic panel and located below the photovoltaic panel; The side-push sensor faces the outside of the short side of the L-shaped connecting frame. One end of the downward pressure sensor extends between the long side of the L-shaped connecting frame and the bottom of the photovoltaic panel. The other end of the downward pressure sensor is connected to the telescopic end of the downward pressure electromagnetic booster. The downward pressure electromagnetic booster is located outside the L-shaped connecting frame. The long side of the L-shaped connecting frame is located between the downward pressure energy storage mechanism and the downward pressure sensor.

[0014] A method for installing an offshore photovoltaic (PV) support system, based on the offshore PV support system described in the claims above, includes the following steps: S1. Determine the photovoltaic installation location according to the size of the photovoltaic panel and complete the construction of the offshore photovoltaic support structure; S2.

S7. The retraction motor drives the downward pressure buckle to retract and press down on the photovoltaic panel until the retraction sensor reaches the preset clamping value.

[0015] The beneficial effects of this invention are as follows: 1. This invention forms a photovoltaic installation position by setting a support frame on the supporting float, which facilitates the positioning of the photovoltaic panel installation position, reduces the difficulty of photovoltaic panel installation and positioning, and improves installation efficiency; at the same time, a connecting clamp is set on the support frame and placed around the photovoltaic installation position. The connecting clamp can be quickly clamped after the photovoltaic panel is placed to achieve stable installation, improve installation efficiency, and improve the installation reliability of the photovoltaic panel by clamping at multiple positions.

[0016] 2. This invention uses a lateral electromagnetic booster to create a relative clamping force in the longitudinal direction, preventing the photovoltaic panel from slipping longitudinally. The downward-pressing electromagnetic booster restricts the vertical swaying of the photovoltaic panel. Simultaneously, the downward-pressing buckle limits the lateral movement of the photovoltaic panel's sidewall, while the photovoltaic slot further restricts vertical swaying, preventing the photovoltaic panel from shaking and bumping under the influence of waves and wind. This improves the installation reliability and lifespan of the photovoltaic panel, is simple and convenient to operate, and increases the installation efficiency. Attached Figure Description

Furthermore, terms such as "first" and "second" are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0023] Example 1 refer to Figure 1 and Figure 2This invention provides a marine photovoltaic (PV) support system, comprising a support float 10, a support frame 20, and connecting clamps. The support float 10 is located outside the support frame 20 to provide support for a photovoltaic panel 50 at sea. The support frame 20 is arranged along the length of the support float 10 to improve the overall structural strength. Photovoltaic mounting positions are arranged sequentially at intervals along the length of the support frame 20. The size of the photovoltaic mounting positions is determined according to the size of the photovoltaic panel 50. The support frame 20 is prefabricated and then installed with the support float 10. The connecting clamps are connected to the support frame 20 and are located around the photovoltaic mounting positions to clamp the photovoltaic panel 50. The photovoltaic panel 50 is quickly clamped and connected using the connecting clamps, reducing the difficulty of operation and improving installation efficiency.

[0024] The material of the support frame 20 can be metal or composite material, such as fiberglass; using composite material can reduce corrosion protection costs and increase service life; when the support frame 20 is metal, it is welded to the connecting fixture; when the support frame 20 is composite material, it is connected to the connecting fixture by structural adhesive.

[0025] Specifically, the support frame 20 includes two support beams 21 and multiple support beams 22. The multiple support beams 22 are equally spaced along the length of the support beams 21, and the support beams 22 are connected between the two support beams 21. Two adjacent support beams 22 and two support beams 21 surround each other to form a photovoltaic installation position. Both the support beams 21 and the support beams 22 are equipped with connecting clamps, and the photovoltaic panel 50 is connected to the connecting clamps.

[0026] refer to Figure 3 To further explain, the connecting clamp includes a transverse clamp 30 and a longitudinal clamp 40. The transverse clamp 30 is set on the support beam 21, and the longitudinal clamp 40 is set on the support longitudinal beam 22. By setting the transverse clamp 30 and the longitudinal clamp 40 on the support frame 20 respectively, the photovoltaic panel 50 can be stably and reliably positioned in the horizontal direction, thereby improving the service life of the photovoltaic panel 50.

[0027] refer to Figure 4 Specifically, the lateral clamp 30 includes a lateral electromagnetic booster 31, a downward electromagnetic booster 32, a lateral electromagnetic controller 33, a lateral base 34, and a downward support 35. The lateral electromagnetic booster 31 and the downward electromagnetic booster 32 are both connected to the lateral electromagnetic controller 33 for signal connection. They are used to control the clamping or loosening of the photovoltaic panel 50 according to the installation or removal of the photovoltaic panel 50, so as to facilitate installation and removal.

[0028] The transverse base 34 is welded to the support beam 21. The fixed end of the lateral electromagnetic booster 31 is connected to the transverse base 34. The telescopic end of the lateral electromagnetic booster 31 faces the transverse side of the photovoltaic installation position and is used to push the photovoltaic panel 50 longitudinally after it is placed. It moves towards each other on both sides of the transverse side of the photovoltaic panel 50 to clamp it and limit the photovoltaic panel 50 in the longitudinal direction.

[0029] The bottom of the downward support 35 is welded to the horizontal base 34. The fixed end of the downward electromagnetic booster 32 is connected to the downward support 35. The telescopic end of the downward electromagnetic booster 32 is set in the vertical direction to clamp the photovoltaic panel 50 in the vertical direction. The telescopic end of the downward electromagnetic booster 32 can be connected to the bottom of the photovoltaic panel 50. The telescopic end of the downward electromagnetic booster 32 pulls the photovoltaic panel 50 tight by moving downward, so that it is limited in the vertical direction.

[0030] Preferably, an L-shaped connecting frame 51 is provided on the horizontal side of the photovoltaic panel 50. The short side of the L-shaped connecting frame 51 is vertically connected to the bottom of the photovoltaic panel 50, and the long side of the L-shaped connecting frame 51 is parallel to the bottom of the photovoltaic panel 50 and located below the photovoltaic panel 50. At this time, the telescopic end of the downward pressing electromagnetic booster 32 extends into the U-shaped groove formed by the L-shaped connecting frame 51 and the bottom of the photovoltaic panel 50. The telescopic end of the downward pressing electromagnetic booster 32 extends downward and presses down on the photovoltaic panel 50 through the L-shaped connecting frame 51, thereby limiting the photovoltaic panel 50 in the vertical direction and preventing it from shaking.

[0031] To further explain, in order to improve clamping reliability and control the clamping force on the photovoltaic panel 50, the lateral clamp 30 also includes a side push sensor 36 and a downward pressure sensor 37. Both the side push sensor 36 and the downward pressure sensor 37 are connected to the lateral electromagnetic controller 33. The side push sensor 36 is located on the telescopic end of the lateral electromagnetic booster 31, so that when the photovoltaic panel 50 is clamped in the longitudinal direction, the side push sensor 36 is located between the telescopic end of the lateral electromagnetic booster 31 and the photovoltaic panel 50. The side push sensor 36 is used to obtain the current force of the photovoltaic panel 50 in the longitudinal direction. The lateral electromagnetic controller 33 can preset a side push value. When the data measured by the side push sensor 36 is less than the preset side push value, the lateral electromagnetic booster 31 extends. When the data measured by the side push sensor 36 reaches the preset side push value, it stops, thereby achieving long-term effective longitudinal clamping of the photovoltaic panel 50.

[0032] Similarly, the pressure sensor 37 is set in the U-shaped groove formed by the L-shaped connecting frame 51 and the bottom of the photovoltaic panel 50. The pressure sensor 37 is connected to the telescopic end of the pressure electromagnetic booster 32. The pressure electromagnetic booster 32 is located on the outside of the L-shaped connecting frame 51. When the pressure electromagnetic booster 32 retracts, it pulls the pressure sensor 37 downward, and the pressure sensor 37 pushes the L-shaped connecting frame 51 downward to clamp the photovoltaic panel 50. The horizontal electromagnetic controller 33 can preset the pressure value. The horizontal electromagnetic controller 33 controls whether the pressure electromagnetic booster 32 continues to retract according to the preset pressure value, so as to further stabilize and reliably clamp the photovoltaic panel 50.

[0033] To further explain, the transverse clamp 30 also includes a downward energy storage mechanism 38. The bottom of the downward energy storage mechanism 38 is connected to the transverse base 34. The downward energy storage mechanism 38 is located on one side of the downward support 35 and directly below the downward sensor 37. After the photovoltaic panel 50 is installed, the L-shaped connecting frame 51 is located between the downward energy storage mechanism 38 and the downward sensor 37. When the L-shaped connecting frame 51 moves downward, it will compress the downward energy storage mechanism 38, so that when the photovoltaic panel 50 is removed, the downward energy storage mechanism 38 can push the photovoltaic panel 50 to rise during the upward process of the downward electromagnetic booster 32.

[0034] Preferably, the side push sensor 36 is slidably connected to the transverse base 34 via the sliding rail 39, which improves the mobility reliability of the side push sensor 36; at the same time, it is preferable to provide buffer pads on the outer surface of the side push sensor 36, the upper surface of the pressure storage mechanism 38, the lower surface of the pressure sensor 37, and the inner wall of the U-shaped groove to reduce the damage caused by clamping and the clamping process, and improve the service life.

[0035] refer to Figure 5 To further explain, the longitudinal clamp 40 includes a longitudinal support 41, a retracting motor 42, and a pressing buckle 43. The longitudinal support 41 is set on the top of the longitudinal beam 22 of the bracket. The fixed end of the retracting motor 42 is connected to the top of the longitudinal support 41. The pressing buckle 43 is connected to the telescopic end of the retracting motor 42. Photovoltaic slots 45 that cooperate with the side wall of the photovoltaic panel 50 are opened on both the left and right sides of the pressing buckle 43.

[0036] During installation, the retracting motor 42 retracts downward, driving the pressing buckle 43 to move downward, so that the photovoltaic slot 45 on the pressing buckle 43 engages with the longitudinal side of the photovoltaic panel 50, limiting the photovoltaic panel 50 in the lateral and vertical directions, thereby achieving stable clamping of the photovoltaic panel 50 in multiple directions and angles, which is convenient and reliable to operate and improves the clamping and installation efficiency of the photovoltaic panel 50.

[0037] Preferably, the longitudinal clamp 40 also includes a retraction sensor 44. The pressing buckle 43 is connected to the telescopic end of the retraction motor 42 through the retraction sensor 44. It can also preset the clamping value. When the retraction sensor 44 reaches the preset clamping value, the retraction motor 42 stops, thus completing the clamping of the photovoltaic panel 50.

[0038] Example 2 Based on the offshore photovoltaic support structure provided in Embodiment 1, this embodiment provides an installation method for an offshore photovoltaic support structure, including the following steps: S1. Determine the photovoltaic installation location according to the size of the photovoltaic panel 50 and complete the construction of the offshore photovoltaic support structure; S2, the lateral electromagnetic controller 33 controls the lateral electromagnetic booster 31 to retract and controls the downward electromagnetic booster 32 to rise. S3, the retracting motor 42 drives the downward pressing buckle 43 to rise, leaving room for installation; S4. Place the photovoltaic panel 50 in the photovoltaic installation position so that the L-shaped connecting frame 51 can be matched with the pressure sensor 37. S5. The transverse electromagnetic controller 33 controls the lateral electromagnetic booster 31 to move and press the outer side of the L-shaped connecting frame 51 longitudinally until the lateral push sensor 36 reaches the preset lateral push value. S6. The horizontal electromagnetic controller 33 controls the downward electromagnetic booster 32 to retract and press down on the long side of the L-shaped connecting frame 51 until the downward sensor 37 reaches the preset downward value. S7. The retraction motor 42 drives the downward pressure buckle 43 to retract and press down on the photovoltaic panel 50 until the retraction sensor 44 reaches the preset clamping value.
