Description

Technical Field

[0001] This invention relates to the field of photovoltaic technology, and in particular to a water surface photovoltaic floating system that is adaptively adjusted to resist wind and waves. Background Technology

[0002] The new energy power generation industry is booming. Land-based photovoltaic power plants require a large amount of land, while vast lakes and oceans provide new space for photovoltaic development, giving rise to the development of floating photovoltaic technology. However, the frequent waves and winds in the water environment, coupled with the fact that traditional floating photovoltaic structures are mostly fixed structures, make them susceptible to damage to components or deviation in power generation angle due to wave impact and swaying. This makes them unable to adapt to complex water conditions, becoming a key bottleneck for the large-scale application of floating photovoltaics. Summary of the Invention

[0003] To overcome these shortcomings, the technical problem to be solved by this invention is: how to improve the stability and adaptability of the floating photovoltaic system.

[0004] The technical solution adopted by this invention to solve its technical problem is: A wind and wave resistant adaptive adjustment water surface photovoltaic floating body system includes a photovoltaic panel assembly and a floating support assembly. The floating support assembly includes a frame body with honeycomb-shaped gaps. The photovoltaic panel assembly is disposed on the upper end of the frame body. A buffer structure is provided at the connection position between the photovoltaic panel assembly and the frame body. An anchoring assembly is provided on the periphery of the frame body. The anchoring assembly is used to position the frame body at a specified water surface position.

[0005] Furthermore, the aforementioned honeycomb-shaped voids are regular hexagonal and are sealed cavities, and multiple such honeycomb-shaped voids are evenly distributed vertically within the aforementioned frame.

[0006] Furthermore, the aforementioned buffer structure includes multiple hydraulic buffers, which are evenly disposed between the photovoltaic panel assembly and the frame.

[0007] Furthermore, multiple cleaning brushes are provided on the periphery of the aforementioned frame.

[0008] Furthermore, the aforementioned anchoring assembly includes a plurality of biomimetic anchors evenly arranged on the outside of the aforementioned frame, with the anchoring ends of the aforementioned biomimetic anchors connected to the ground at the bottom of the water.

[0009] Furthermore, the aforementioned biomimetic anchor body includes a retractable pull rope connected to the aforementioned frame body, and an anchor rod is connected to the end of the retractable pull rope away from the aforementioned frame body. Multiple anchor claws are provided extending outward from the periphery of the aforementioned anchor rod.

[0010] Furthermore, the aforementioned anchor bolt is conical in shape.

[0011] Furthermore, the aforementioned photovoltaic panel assembly includes a photovoltaic panel body, the upper surface of which is bonded with an EVA film and the lower surface is coated with a tetrafluoroethylene wear-resistant coating.

[0012] Furthermore, it also includes a cleaning component disposed on the upper part of the photovoltaic panel assembly, which is used to clean the working surface of the photovoltaic panel assembly.

[0013] Furthermore, the cleaning component includes a guide rail structure slidably disposed on the upper end of the photovoltaic panel assembly, a roller brush structure movably disposed on the guide rail structure, a driving structure disposed on the photovoltaic panel assembly, and a driving end of the driving structure driving the roller brush structure to move along the guide rail structure; the roller brush structure is provided with a water absorption component and a water spraying component, and the water absorption component absorbs water and then sprays it onto the photovoltaic panel assembly through the water spraying component.

[0014] The beneficial effects of this invention are: By setting up a frame with honeycomb-like gaps, the honeycomb structure has optimal mechanical stability and can evenly distribute the wave impact force to the six stress surfaces of the entire frame, avoiding frame deformation caused by local stress concentration; at the same time, a buffer structure is set at the connection between the photovoltaic panel module and the frame, which can further attenuate the impact force.

[0015] The honeycomb grid has a closed cavity structure and the buoyancy is evenly distributed along the frame, which can ensure that the photovoltaic panel always maintains a stable floating state and avoid water ingress or reduced power generation efficiency due to insufficient local buoyancy.

[0016] The standardized dimensions of the cellular frame make it easy to assemble photovoltaic arrays of any size, and the expansion joints reserved between adjacent frames can accommodate the slight deformation of the frame caused by wind and waves, preventing the entire array from collapsing. Compared with customized frames, it is more flexible and economical.

Detailed Implementation

[0019] The invention will be further described below with reference to the accompanying drawings.

[0020] like Figures 1-4 As shown in the embodiment of this application, a wind and wave-resistant adaptive adjustment water surface photovoltaic floating body system is proposed, including a photovoltaic panel assembly 1 and a floating support assembly. The floating support assembly includes a frame body 2 with honeycomb-shaped gaps. The photovoltaic panel assembly 1 is disposed on the upper end of the frame body 2. A buffer structure 3 is provided at the connection position between the photovoltaic panel assembly 1 and the frame body 2. An anchoring assembly is provided on the periphery of the frame body 2. The anchoring assembly is used to position the frame body 2 at a specified water surface position.

[0021] First, it should be stated that by setting up a honeycomb-shaped frame body 2, the honeycomb structure has good mechanical stability and can evenly distribute the wave impact force to the six stress surfaces of the entire frame, avoiding frame deformation caused by local stress concentration; at the same time, a buffer structure 3 is set at the connection position between the photovoltaic panel module 1 and the frame body 2, which can further reduce the impact force.

[0022] The aforementioned honeycomb-shaped gaps are regular hexagons and are sealed cavities. Multiple honeycomb-shaped gaps are evenly distributed in the aforementioned frame body 2. The honeycomb grid is a closed cavity structure and is vertically set in the frame body 2, so that the buoyancy is evenly applied to the frame body 2, which can ensure that the photovoltaic panel always maintains a horizontal posture and avoid water ingress or power generation efficiency reduction of the photovoltaic panel due to insufficient local buoyancy.

[0023] The aforementioned buffer structure 3 includes multiple hydraulic units, and the multiple hydraulic buffers are evenly arranged between the photovoltaic panel assembly 1 and the frame 2. Specifically, the upper and lower ends of the hydraulic units are respectively connected to the upper ends of the photovoltaic panel assembly 1 and the frame 2. In the case of frequent waves in the water, the overall structure will shake. The buffer mechanism of the hydraulic units can buffer the rigid force of the shaking, so as to avoid damage or deviation of the power generation angle caused by the violent shaking of the overall structure.

[0024] In this embodiment, a 2mm thick EVA film is bonded to the upper surface of the photovoltaic panel assembly 1, and a PTFE wear-resistant coating is sprayed onto the lower surface. During the installation of the overall structure, the honeycomb deformable frame 2 is assembled according to the specific dimensions of the photovoltaic panel assembly 1. The base of the photovoltaic panel assembly 1 and the frame 2 are connected by M6 stainless steel and fixed supports, specifically secured with bolts equipped with anti-loosening washers.

[0025] Multiple cleaning brushes 5 are provided around the perimeter of the frame 2. The cleaning brushes 5 are positioned at the edge of the frame 2, so that wind and waves can drive the cleaning brushes 5 to clean the edge of the frame 2, preventing aquatic plants and animals from adhering. Specifically, the cleaning brushes 5 include brush structures that are movably set on the outside of the frame 2. Under the action of wind and waves, the brush structures move on the outer wall of the frame and achieve a washing effect on the outside of the frame 2, preventing aquatic plants and animals from adhering and increasing the local weight of the overall structure, and further improving the working stability of the overall structure.

[0026] The aforementioned anchoring assembly includes multiple biomimetic anchor bodies 4 evenly arranged on the outside of the aforementioned frame 2, with the anchoring end of the biomimetic anchor body 4 connected to the ground at the bottom of the water; the multiple biomimetic anchor bodies 4 are inserted into the silt at the bottom of the water for fixation, ensuring that the overall structure will not move randomly in wind and waves.

[0027] The aforementioned biomimetic anchor 4 includes a retractable pull rope 41 connected to the aforementioned frame 2. Specifically, the retractable pull rope 41 is a retractable nylon cable. An anchor rod 42 is connected to the end of the retractable pull rope 41 furthest from the frame 2. Multiple anchor claws 43 extend outwards from the periphery of the anchor rod 42. The multiple anchor claws 43 are designed to ensure sufficient gripping effect, preventing the anchor rod 42 from detaching from the seabed. In this embodiment, the frame 2 is specifically cubic, with a set of biomimetic anchor bodies 4 and retractable pull ropes 41 at each of the four corners. The cable diameter exceeds 18mm, and the telescopic drive is a micro servo motor combined with a winch structure. The telescopic drive allows for real-time control of the length of each retractable pull rope 41, ensuring the retractable pull rope 41 remains taut and guaranteeing the stability of the overall structure. Specifically, the aforementioned anchor rod 42 is conical, facilitating installation in underwater silt.

[0028] The aforementioned photovoltaic panel assembly 1 includes a photovoltaic panel body, the upper surface of which is bonded with an EVA film and the lower surface is sprayed with a tetrafluoroethylene wear-resistant coating to ensure sufficient wear resistance and protection.

[0029] It also includes a cleaning component 6 disposed on the upper end of the photovoltaic panel assembly 1, which is used to clean the working surface of the photovoltaic panel assembly 1.

[0030] Specifically, the cleaning component 6 includes a guide rail structure 7 disposed on the upper end of the photovoltaic panel assembly 1. A roller brush structure is movably disposed on the guide rail structure 7. The photovoltaic panel assembly 1 is provided with a driving structure. The driving end of the driving structure drives the roller brush structure to move along the guide rail structure 7. The roller brush structure is provided with a water absorption component and a water spraying component. After the water absorption component absorbs water, it is sprayed onto the photovoltaic panel assembly 1 by the water spraying component. In use, the driving structure drives the roller brush structure to move on the guide rail structure 7, and the roller brush structure cleans the surface of the photovoltaic panel assembly 1. Specifically, the driving component is a servo motor structure. Specifically, it can be a screw-slider structure that pushes the roller brush structure to clean the surface of the photovoltaic panel assembly 1. The roller brush structure can be a fixed shaft 62 connected to the slider. A hollow rotating cylinder 61 is disposed on the outside of the fixed shaft 62. A brush is disposed on the outside of the hollow rotating cylinder 61. The brush abuts against the surface of the photovoltaic panel assembly 1. During the movement, the brush abuts against the surface of the photovoltaic panel. Under the action of friction, the hollow rotating cylinder 61 rotates to achieve the cleaning effect.

[0031] Furthermore, the water absorption assembly includes a water absorption pipe 64, one end of which extends underwater and the other end is connected to a miniature water pump. The output end of the miniature water pump is connected to the hollow rotating cylinder 61. The water spraying assembly includes a water spray hole 63 opened on the outer wall of the hollow rotating cylinder 61. During operation, the miniature water pump draws water into the hollow rotating cylinder 61. As the hollow rotating cylinder 61 rotates, water is sprayed out or overflows from the water spray hole 63, working in conjunction with the brush to clean the surface of the photovoltaic panel.

[0032] In summary, this invention proposes a wind and wave-resistant adaptive adjustment water surface photovoltaic floating system. The hexagonal honeycomb structure offers optimal mechanical stability, evenly distributing wave impact force across the six stress surfaces of the entire frame, preventing frame deformation caused by localized stress concentration. Combined with hydraulic buffer components at the nodes, the impact force can be further attenuated. The honeycomb grid, being a closed cavity structure with buoyancy evenly distributed along the frame, ensures the photovoltaic panels remain horizontal, preventing water ingress or reduced power generation efficiency due to insufficient localized buoyancy. The aluminum alloy honeycomb frame is significantly lighter than a solid frame of the same size, allowing for lifting with a traditional crane without the need for large specialized equipment, reducing transportation and installation difficulties on water. The standardized dimensions of the honeycomb frame facilitate the assembly of photovoltaic arrays of any size, and the pre-reserved expansion joints between adjacent frames accommodate minor deformations caused by wind and waves, preventing overall array collapse. Compared to customized frames, this system is more flexible and economical. The cleaning brush 5 and cleaning component 6 solve the problems of aquatic plant and animal attachment and the difficulty in cleaning the surface of the water surface photovoltaic system.
