Description

Technical Field

[0001] This invention relates to the field of photovoltaics, and more particularly to a photovoltaic module for use on water surfaces. Background Technology

[0002] Currently, most of the photovoltaic (PV) module supports on water surfaces are fixed-tilt supports, and they cannot be adjusted according to changes in the application environment. Often, one set of PV module supports is used for one project, and another set of PV module supports is used for one angle. Therefore, their versatility is poor.

[0003] Some existing water-surface photovoltaic panels have been improved based on the aforementioned fixed tilt brackets, allowing the photovoltaic panels to be tilted and fixed at a certain angle relative to the brackets during installation, thus giving these photovoltaic panels a certain degree of environmental adaptability.

[0004] However, once this type of photovoltaic panel is installed at a certain angle, the angle remains fixed and cannot be adjusted according to factors such as morning / evening, season, or weather. Therefore, the range of adjustable angles is still limited. Furthermore, if the angle is adjusted, the connection between the bracket and the photovoltaic panel needs to be disassembled manually and then re-fixed after the angle is readjusted. The process of adjusting the angle of a large number of photovoltaic panels is extremely cumbersome and inconvenient. Summary of the Invention

[0005] The purpose of this invention is to provide a photovoltaic module for water surfaces that can improve the light adaptation angle of water surface photovoltaic equipment and reduce the cumbersome steps of adjusting the angle of photovoltaic panels.

[0006] To address the aforementioned technical problems, this invention provides a photovoltaic module for water surfaces, comprising a buoyancy platform, an adjustment plate rotatably mounted on the buoyancy platform, and a support frame mounted on the adjustment plate in an arc-shaped structure. An adjustment rod is movably mounted inside the support frame, and the photovoltaic panel is connected to the adjustment rod so that when the adjustment rod moves relative to the support frame, the tilt angle of the photovoltaic panel changes, and when the adjustment plate rotates relative to the buoyancy platform, the orientation angle of the photovoltaic panel changes.

[0007] Furthermore, at least two guide rods are arranged opposite each other on the upper part of the buoyancy platform, and the adjustment plate is provided with guide grooves that match the guide rods, so that when the adjustment plate rotates relative to the buoyancy platform, the guide rods slide relative to the guide grooves, and the drive platform is mounted on several guide rods. The drive platform is provided with a drive component so that the drive component drives the adjustment plate to rotate.

[0008] Furthermore, the support frame has an adjustment groove inside, and the adjustment groove has connecting pipes at both ends. The two ends of the drive pipe are inserted into two adjacent connecting pipes, and the drive pipe has a drive groove inside, so that the adjustment groove and the drive groove are connected through the connecting pipe. The adjustment rod is movably installed in the adjustment groove, and the drive groove is movably installed in the drive groove. The drive groove and the adjustment groove carry liquid medium, so that when the drive rod moves along the drive groove, the adjustment rod moves relative to the adjustment groove.

[0009] Furthermore, a first opening is provided on the side of the adjustment groove, and a connecting block is provided on the side of the adjustment rod so that the back side of the photovoltaic panel is connected to the adjustment rod through the connecting block. A second opening is provided on the side of the drive groove, and a drive block is provided on the side of the drive rod. A drive wheel matching the drive block is rotatably provided on the adjustment plate so that when the drive wheel rotates, the drive rod reciprocates along the drive groove.

[0010] Furthermore, the output end of the drive unit is axially telescopically connected to an output stake, and a plurality of output gear teeth are spaced apart on the outer periphery of the output stake. A drive cavity is opened in the middle of the adjustment plate, and a plurality of first driven gear teeth matching the output gear teeth are spaced apart circumferentially in the drive cavity. The inner ring of the drive wheel has second driven gear teeth matching the output gear teeth, and the outer ring of the drive wheel has third driven gear teeth matching the drive block, so that when the output stake telescopically extends or retracts relative to the output end, the output gear teeth switch between the first driven gear teeth and the second driven gear teeth.

[0011] Furthermore, the opposing surfaces of the first driven gear tooth and the second driven gear tooth are each provided with a first guide slope, and the output gear tooth is provided with a second guide slope on both sides facing the first driven gear tooth and the second driven gear tooth.

[0012] Furthermore, a piston rod is provided on the side of the buoyancy platform near the adjustment plate. The end of the piston rod has a limiting ring, and the end of the output pile has a connecting buckle that engages with the limiting ring. The connecting buckle has a C-shaped structure so that the piston rod drives the output pile to extend and retract through the connecting buckle.

[0013] Furthermore, the drive wheel has a positioning ring on the side near the adjusting plate, and the adjusting plate has an annular groove so that the positioning ring is rotatably connected in the annular groove. A pressure plate is installed in the annular groove so that the pressure plate limits the positioning ring. The drive wheel has several hollowed-out grooves along the circumference, and the hollowed-out grooves correspond to the pressure plate.

[0014] Furthermore, several fourth driven gear teeth are arranged opposite each other on both sides of the adjustment plate so that adjacent adjustment plates can rotate synchronously through the meshing of the chain and the fourth driven gear teeth.

[0015] Furthermore, the outer periphery of the buoyancy platform is provided with several lifting rings so that adjacent buoyancy platforms can be connected through the lifting rings.

[0016] The beneficial effects of this invention are as follows: the buoyancy platform stabilizes the upper photovoltaic panels and other structures on the water surface, ensuring the stable use of the photovoltaic panels on the water surface. When it is necessary to adjust the angle of the photovoltaic panels, the adjustment plate rotates relative to the buoyancy platform, and the adjustment rod rotates along the support frame of the arc structure. This allows the photovoltaic panels to be adjusted in the horizontal direction with the adjustment plate and in the vertical direction with the adjustment rod. The combined adjustment of these two methods ensures the adaptability of the photovoltaic panels to different light conditions, thereby improving the efficiency of solar power generation.

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention are within the scope of protection of the present invention.

[0024] Those skilled in the art should understand that, in the disclosure of this invention, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limiting this invention.

[0025] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0026] like Figures 1-5 The present invention provides a photovoltaic module for use on a water surface, including a buoyancy platform 1, an adjustment plate 2 rotatably mounted on the buoyancy platform 1, and a support frame 3 mounted on the adjustment plate 2 and arranged in an arc shape. An adjustment rod 4 is movably mounted inside the support frame 3. A photovoltaic panel 5 is connected to the adjustment rod 4 so that when the adjustment rod 4 moves relative to the support frame 3, the tilt angle of the photovoltaic panel 5 changes. When the adjustment plate 2 rotates relative to the buoyancy platform 1, the orientation angle of the photovoltaic panel 5 changes.

[0027] A buoyancy platform is used to stabilize the upper photovoltaic panels and other structures on the water surface, ensuring stable operation of the photovoltaic panels. When the angle of the photovoltaic panels needs to be adjusted, the adjustment plate rotates relative to the buoyancy platform, and the adjustment rod rotates along the support frame of the arc structure. This allows the photovoltaic panels to be adjusted horizontally with the adjustment plate and vertically with the adjustment rod. The combined adjustment of these two methods ensures the adaptability of the photovoltaic panels to different lighting conditions, thereby improving the efficiency of solar power generation.

[0028] The buoyancy platform is similar to existing floating pontoons and other structures, and its interior is made of hollow or lightweight materials.

[0029] In one embodiment of this solution, the support frame is arranged in a semi-circular structure, and the adjusting rod inside it is also arranged in an arc shape, so that when the adjusting rod moves the photovoltaic panel along the support frame, the angle of the photovoltaic panel is adjusted with the semi-circular structure.

[0030] Preferably, at least two guide rods 6 are arranged opposite each other on the upper part of the buoyancy platform 1, and the adjustment plate 2 is provided with a guide groove 7 that matches the guide rods 6, so that when the adjustment plate 2 rotates relative to the buoyancy platform 1, the guide rods 6 and the guide groove 7 slide relative to each other, and the drive platform 8 is mounted on several guide rods 6, and the drive platform 8 is provided with a drive component 9, so that the drive component 9 drives the adjustment plate 2 to rotate.

[0031] Specifically, the adjustment plate is controlled to rotate by the drive component. During the rotation, the rotation of the adjustment plate is guided and limited by the cooperation of the guide rod and the guide groove, ensuring that its rotation in the horizontal direction is smooth and accurate, and preventing the adjustment plate from rotating too much or deviating. At the same time, the drive platform supports the drive component to make it run stably, and the entire drive platform can be disassembled from the guide rod for easy maintenance later.

[0032] The guide rod can be connected to the drive platform by bolts, the drive component can be a motor, and it can be equipped with a separate independent battery to power the motor, which is charged by the photovoltaic panel.

[0033] Preferably, the support frame 3 has an adjustment groove 10 inside, the adjustment groove 10 has connecting pipes 11 at both ends, the drive pipe 12 is inserted into two adjacent connecting pipes 11 at both ends, and the drive pipe 12 has a drive groove 13 inside, so that the adjustment groove 10 and the drive groove 13 are connected through the connecting pipes 11. The adjustment rod 4 is movably installed in the adjustment groove 10, and the drive groove 13 is movably installed with a drive rod 14. The drive groove 13 and the adjustment groove 10 carry liquid medium, so that when the drive rod 14 moves along the drive groove 13, the adjustment rod 4 moves relative to the adjustment groove 10.

[0034] Specifically, when it is necessary to adjust the height and angle of the photovoltaic panel, the drive rod moves in the drive groove, pushing the liquid medium to transmit pressure, so that the adjustment rod moves synchronously in the adjustment groove, thereby driving the photovoltaic panel to rise and fall along the arc surface of the support frame, achieving precise adjustment of the pitch angle; this hydraulic transmission structure operates smoothly and can effectively avoid vibration caused by wind and waves or compression problems caused by gaseous media, improving the system's adaptability and stability in aquatic environments.

[0035] In one embodiment of this solution, the liquid medium is selected as waterproof and corrosion-resistant inert hydraulic oil, which can maintain fluidity over a wide temperature range and ensure reliable operation throughout the year.

[0036] Preferably, the adjustment groove 10 has a first opening 15 on its side, the adjustment rod 4 has a connecting block 16 on its side, so that the back side of the photovoltaic panel 5 is connected to the adjustment rod 4 through the connecting block 16, the drive groove 13 has a second opening 17 on its side, the drive rod 14 has a drive block 18 on its side, and the adjustment plate 2 is rotatably provided with a drive wheel 19 that matches the drive block 18, so that when the drive wheel 19 rotates, the drive rod 14 reciprocates along the drive groove 13.

[0037] Specifically, when the drive wheel rotates, the drive block drives the drive rod to move back and forth along the drive groove, thereby pushing the liquid medium to transmit pressure between the drive groove and the adjustment groove, so that the adjustment rod moves synchronously and achieves precise control of the photovoltaic panel's pitch angle. The setting of the first opening and the second opening can ensure the sealing and flexibility of the adjustment rod and the drive rod during the movement process, avoid jamming caused by structural interference, and facilitate assembly and subsequent maintenance.

[0038] Preferably, the output end 20 of the driving component 9 is axially telescopically connected to an output stake 21. The output stake 21 has a plurality of output gear teeth 22 spaced apart on its outer periphery. The adjusting plate 2 has a driving cavity 23 in the middle. The driving cavity 23 has a plurality of first driven gear teeth 24 that match the output gear teeth 22 spaced apart on its circumference. The inner ring of the driving wheel 19 has second driven gear teeth 25 that match the output gear teeth 22. The outer ring of the driving wheel 19 has third driven gear teeth 26 that match the driving block 18. This allows the output gear teeth 22 to switch between the first driven gear teeth 24 and the second driven gear teeth 25 when the output stake 21 telescopically extends or retracts relative to the output end 20.

[0039] Specifically, by switching the meshing between the output gear teeth and the first driven gear teeth and the second driven gear teeth, when it is necessary to drive the adjustment plate or drive wheel to rotate, the height position of the output gear teeth can be switched by the extension and retraction of the output pile relative to the output end to adapt to the driven gear teeth at different height positions, thereby driving the photovoltaic panel to adjust at different angles and orientations through the same driving component.

[0040] The expansion and contraction mechanism between the output pile and the output end can be achieved by using a combination of a sliding groove and a slider, so that while the output end and the output pile can expand and contract, the output end can also drive the output pile to rotate.

[0041] Preferably, the opposing surfaces of the first driven gear tooth 24 and the second driven gear tooth 25 are provided with a first guide slope 27, and the output gear tooth 22 is provided with a second guide slope 28 on both sides facing the first driven gear tooth 24 and the second driven gear tooth 25.

[0042] Specifically, during the extension and retraction adjustment of the output pile, the inclined surfaces of the first guide slope and the second guide slope cooperate to guide the output gear teeth to smoothly slide into or out of the meshing position with the first driven gear teeth and the second driven gear teeth, thereby reducing meshing impact and improving shifting smoothness.

[0043] Preferably, a piston rod 29 is provided on the side of the buoyancy platform 1 near the adjusting plate 2. The end of the piston rod 29 has a limiting ring 30, and the end of the output pile 21 has a connecting buckle 31 that engages with the limiting ring 30. The connecting buckle 31 has a C-shaped structure so that the piston rod 29 drives the output pile 21 to extend and retract through the connecting buckle 31.

[0044] Specifically, when controlling the extension and retraction switching state of the output pile, the piston rod is extended and retracted, and then the output pile is pushed or pulled by the connecting buckle to rise or fall, so as to improve the smoothness of the overall switching process of the output pile.

[0045] The C-shaped connecting buckle can engage or disengage the limiting ring from the C-shaped opening, facilitating assembly and disassembly. It also maintains connection stability during extension and retraction, and ensures that the rotation of the output pile is not interfered with by the linear motion of the piston rod.

[0046] In one embodiment of this solution, the buoyancy platform has a hydraulic cylinder for controlling the extension and retraction of the piston rod.

[0047] Preferably, the drive wheel 19 has a positioning ring 32 on the side near the adjusting plate 2, and the adjusting plate 2 has an annular groove 33 so that the positioning ring 32 is rotatably connected in the annular groove 33. A pressure plate 34 is installed in the annular groove 33 so that the pressure plate 34 limits the positioning ring 32. The drive wheel 19 has a plurality of hollow grooves 35 along the circumference, and the hollow grooves 35 correspond to the pressure plate 34.

[0048] Specifically, the positioning ring is pressed by the pressure plate, so that the positioning ring can rotate along the ring groove under the drive of the output pile without sliding or falling out of the ring groove, thus ensuring the stability and reliability of the drive wheel rotation. The corresponding setting of the hollow groove and the pressure plate makes it easy for the operator to insert the tool head into the pressure plate position through the hollow groove when installing bolts and other connecting parts on the pressure plate, so as to ensure the smooth installation or removal of the pressure plate.

[0049] It is worth mentioning that when adjusting the angle of the photovoltaic panel, the rotation angle of the adjustment plate should be adjusted first, and then the rotation position of the adjustment rod should be adjusted. After the adjustment rod is adjusted, the pitch angle of the photovoltaic panel can be limited by the motor and pressure plate. When it is necessary to change the angle of the photovoltaic panel, it is recommended to first move the adjustment plate to its maximum stroke at one end, and then limit the connection block through the first opening to ensure the accuracy of the current angle of the photovoltaic panel. Then adjust the adjustment plate and adjustment rod in sequence.

[0050] Preferably, a plurality of fourth driven gear teeth 36 are arranged opposite to each other on both sides of the adjusting plate 2 so that adjacent adjusting plates 2 can rotate synchronously through the meshing of the chain and the fourth driven gear teeth 36.

[0051] Specifically, the adjustment plates on multiple buoyancy platforms are connected into a whole by a chain. When the chain meshes with the fourth driven wheel, the rotation of a single adjustment plate can drive multiple adjustment plates to rotate synchronously, thereby achieving uniform angle adjustment of the photovoltaic array. Furthermore, the chain can be used to circumferentially limit the adjustment plates to ensure the stability of the horizontal angle of the photovoltaic panels.

[0052] It is worth mentioning that the chain structure is mounted on at least two rotating wheels, and the rotating wheels can be installed on the side of any buoyancy platform, or a separate buoyancy platform can be added to support the rotating wheels, so as to enhance the stability and load-bearing capacity of the chain drive.

[0053] Preferably, a plurality of lifting rings 37 are arranged on the outer periphery of the buoyancy platform 1 so that adjacent buoyancy platforms 1 can be connected by the lifting rings 37.

[0054] Specifically, by connecting the various lifting rings, the positions of each buoyancy platform on the water surface are relatively fixed, preventing the array from shifting due to water flow or waves, thereby ensuring uniform stress on the photovoltaic panels and safe operation.

[0055] This invention is not limited to the preferred embodiments described above. Anyone can derive other products in various forms under the guidance of this invention. However, regardless of any changes in shape or structure, any technical solution that is the same as or similar to this application falls within the protection scope of this invention.
