Description

Technical Field

[0001] This utility model relates to the field of offshore photovoltaic installation, and more specifically, to a floating offshore photovoltaic sliding installation support. Background Technology

[0002] Traditional floating photovoltaic (PV) installations require assembling floating pontoons on shore and transporting them by boat to designated waters before installing the supporting components on the water. This approach has several drawbacks: water transport relies on ships, leading to high costs and low efficiency; handling materials on the water is difficult for workers, increasing the risk of material loss due to operational errors; the complex water environment presents significant safety hazards and challenges in quality control; and construction progress is heavily influenced by weather and water conditions, resulting in high management costs. Furthermore, traditional installation methods require component fixing on the water, making standardized operations difficult; component angle adjustments rely on manual operation, resulting in poor adaptability, especially in strong winds and waves at sea, where installation accuracy and stability are difficult to guarantee.

[0003] How to invent a floating photovoltaic sliding mounting support for marine applications to improve these problems has become an urgent issue for those skilled in the art. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a floating photovoltaic sliding installation support for the sea, which aims to improve the problems of high cost and low efficiency of water transportation, large material loss due to falling into the water, prominent safety hazards, difficulty in quality control and high management costs in traditional water surface photovoltaic installation construction, as well as the difficulty in standardizing component fixing, strong reliance on manual angle adjustment, and insufficient installation accuracy and stability in strong wind and wave environments at sea.

[0005] This utility model is implemented as follows: a marine floating photovoltaic sliding installation support includes a floating part for installing photovoltaic modules and connected to a cableway traction system, a sliding part for connecting a ground-based water entry track, and a bidirectional rotating structure for connecting the floating part and the sliding part. The floating part includes a buoy and a connecting structure. The buoy is a hollow cylinder. The connecting structure is rotatably connected to the bidirectional rotating structure to achieve horizontal rotation. The sliding part includes a support member, on which several rolling elements are rotatably mounted. The bidirectional rotating structure is fixedly connected above the support member and is provided with a longitudinal rotating mechanism.

[0006] In a preferred embodiment of this utility model, the outer wall of the pontoon is provided with structures for installing photovoltaic modules and for connecting the cableway traction system.

[0007] In a preferred embodiment of this utility model, the connecting structure includes an arc-shaped support plate, the arc of which is consistent with the arc of the outer wall of the float. The float is fixedly connected to the top surface of the arc-shaped support plate, and ribs are fixedly connected to both ends of the bottom surface of the arc-shaped support plate. The bottom ends of the two ribs are respectively fixedly installed at both ends of the upper surface of the horizontal conversion plate. A connecting hole is provided at the center of the upper surface of the horizontal conversion plate for connecting with the bidirectional rotating structure.

[0008] In a preferred embodiment of this utility model, stiffening ribs are integrally formed on the inner walls of both ends of the float, and each stiffening rib is positioned corresponding to a rib plate at one end.

[0009] In a preferred embodiment of this utility model, the bidirectional rotating structure includes a base, with ear plates integrally provided on both sides of the upper surface of the base.

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] Please see Figures 1 to 4 This utility model provides a technical solution: a marine floating photovoltaic sliding installation support, including a floating part for installing photovoltaic modules and connected to a cableway traction system, a sliding part for connecting a ground-to-water track, and a bidirectional rotating structure for connecting the floating part and the sliding part. The floating part includes a buoy 10 and a connecting structure. The buoy 10 is a hollow cylinder. The connecting structure is rotatably connected to the bidirectional rotating structure to achieve horizontal rotation. The sliding part includes a support member, on which several rolling elements are rotatably mounted. The bidirectional rotating structure is fixedly connected above the support member and is provided with a longitudinal rotating mechanism.

[0021] Buoyancy is provided by pontoons 10 to support photovoltaic modules and connect to the cableway traction system, enabling floating and migration in the water. Rolling components (such as rollers) work in conjunction with the ground-based water entry track to slide the photovoltaic modules from land into the sea. The bidirectional rotating structure automatically adapts to changes in the sliding direction and water surface fluctuations through horizontal and vertical linkage. The cableway traction system uses flexible steel wire ropes connected to pontoons 10 (e.g., fixed to the top suspension point of the pontoons with shackles). The angle between the steel wire rope and the sliding direction is ≤30° to avoid interference between cableway tension and track guidance. The cableway support is higher than the end of the track to ensure that the steel wire rope is slack during sliding into the sea, without affecting free sliding.

[0022] Please see Figures 2 to 4 The outer wall of the pontoon 10 is provided with structures for installing photovoltaic modules and for connecting the cableway traction system.

[0023] Several sets of L-shaped supports are welded along the axial direction on the outer wall of the pontoon 10. Each set of supports includes a horizontal crossbar and a vertical column, which are fixed to the pontoon 10 by U-shaped clamps. The photovoltaic modules are bolted to the top of the crossbars. A ring-shaped lifting lug is welded to the top of the pontoon 10 and connected to a cableway traction device (such as a shore winch) by a steel wire rope. The lifting lug is positioned off-center from the pontoon, creating an eccentric tension that assists the pontoon in turning in the water. The same pontoon 10 serves multiple functions, including buoyancy support, module installation, and traction connection, reducing additional connecting parts and improving structural compactness.

[0024] Furthermore, the connecting structure includes an arc-shaped support plate 1, the arc of which is consistent with the arc of the outer wall of the float 10. The float 10 is fixedly connected to the top surface of the arc-shaped support plate 1. Ribs 2 are fixedly connected to both ends of the bottom surface of the arc-shaped support plate 1. The bottom ends of the two ribs 2 are respectively fixedly installed at both ends of the upper surface of the horizontal conversion plate 3. A connecting hole is provided at the center of the upper surface of the horizontal conversion plate 3 for connecting with the bidirectional rotating structure.

[0025] The curved support plate 1 conforms to the outer wall of the pontoon 10, reducing local compressive stress and preventing pontoon deformation. The curved support plate 1, the rib plate 2, and the horizontal conversion plate 3 can be integrally formed to ensure the overall structural strength and improve the stability of the support for the pontoon 10 and the photovoltaic modules.

[0026] Furthermore, stiffening ribs 12 are integrally formed on the inner walls of both ends of the float 10, and each stiffening rib 12 is positioned corresponding to the rib plate 2 at one end.

[0027] The stiffening rib 12 enhances the deformation resistance of the pontoon 10, enabling it to withstand the loads from photovoltaic modules and personnel maintenance. The load of the rib plate 2 is evenly distributed through the wall of the pontoon 10 to the radial rib plate, and then to the annular stiffening rib 12, avoiding stress concentration in local areas of the pontoon.

[0028] Furthermore, the bidirectional rotating structure includes a base 9, with ear plates 8 integrally provided on both sides of the upper surface of the base 9. Each ear plate 8 has a through-hole on its surface, and the two ends of a vertical rotating pin 5 are rotatably connected to the two mounting holes respectively. Two retaining plates 4 are symmetrically and integrally provided on the outer walls of both ends of the vertical rotating pin 5. The top ends of the two retaining plates 4 are fixedly connected to the bottom surface of the horizontal support plate 7. A horizontal rotating pin 6 is integrally provided at the center of the top surface of the horizontal support plate 7. The horizontal rotating pin 6 is inserted into the connecting hole opened on the surface of the horizontal conversion plate 3.

[0029] The vertical rotating pin 5 enables automatic adjustment of the vertical angle to adapt to wave undulations; the horizontal rotating pin 6 enables horizontal turning to adapt to changes in the sliding trajectory or traction direction. The support structure and photovoltaic modules, driven by the traction device, first slide along the track from the shore into the water, then float using the buoyancy of the floats 10, drifting to the designated installation area guided by the cableway. During this process, the bidirectional rotating structure ensures that the support structure adapts to changes in the moving path and traction direction.

[0030] Furthermore, the outer wall of the top end of the horizontal rotating pin 6 is provided with external threads and is connected to an anti-loosening nut 13 through the external threads.

[0031] A detachable connection is achieved between the horizontal conversion plate 3 and the horizontal rotating pin 6. The horizontal conversion plate 3 is rotatably connected to the horizontal rotating pin 6 through a connecting hole. The anti-detachment nut 13 prevents the two from separating while not affecting the rotation of the horizontal conversion plate 3 around the horizontal rotating pin 6. After the bracket and the corresponding photovoltaic module are moved to the designated water area, the floating part can be separated from the bidirectional rotating structure and the sliding part by removing the anti-detachment nut 13, so that the latter two can be recycled and reused.

[0032] Furthermore, the base 9 is fixedly connected to the upper surface of the sliding part 11 support.

[0033] A fixed bidirectional rotating structure transfers the support load to the sliding part, ensuring a smooth sliding process. The base 9 is connected to the sliding part support via several bolts, which are symmetrically arranged. The connecting surfaces are roughened and coated with epoxy resin to increase friction and prevent base displacement during sliding. The bolted connections form rigid nodes, ensuring balanced force on the rolling elements of the sliding part and preventing overload on one side of the rollers.

[0034] Working Principle: First, a cableway is erected from the shore to the designated water area. Both ends of the cableway are fixed to anchorages on the shore and supported by towers. Simultaneously, a ground-based water-entry track is laid on the shore, extending into the water. Photovoltaic modules are fixed to L-shaped brackets on the outer wall of the pontoon 10. The pontoon 10 is connected to a bidirectional rotating structure consisting of a horizontal rotating pin 6, a horizontal support plate 7, a clamping stiffening plate 4, a vertical rotating pin 5, and a base 9 via a connecting structure composed of an arc-shaped support plate 1, ribs 2, and a horizontal conversion plate 3. The base 9 is fixed to the support of the sliding part, and the rollers at the bottom of the support engage with the ground-based water-entry track. The horizontal rotating pin 6 is passed through the connecting hole of the horizontal conversion plate 3 and limited by the release nut 13, ensuring that the horizontal conversion plate 3 can rotate freely around the pin without being clamped. After installation, the rollers of the sliding part are placed on the ground-based water-entry track. The pontoon 10 is connected to the cableway traction system's wire rope via a top lifting lug. After the traction device (such as a winch) is started, the entire assembly slides into the water along the track. During the sliding process, the horizontal rotating pin 6 automatically adjusts the horizontal angle of the pontoon 10 according to the track deviation or traction direction, while the vertical rotating pin 5 adjusts the vertical angle according to the pontoon's water depth and surface fluctuations to ensure the pontoon enters the water smoothly. Once the base 9 detaches from the track, the pontoon 10 floats completely, and the cableway traction system continues to pull the pontoon to the designated water area. Anchors are then deployed and anchor chains are connected to fix the pontoon's position, forming the photovoltaic array. After installation, the nut 13 is loosened to disassemble the horizontal rotating pin 6, and the detached support components are recycled for reuse. The entire process utilizes a dual-axis rotating structure to achieve angle self-adaptation, combining flexible cableway traction with rigid track guidance to efficiently complete the sliding installation and positioning of the photovoltaic modules.

[0035] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
