[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] Reference Figures 1 to 5 This utility model discloses a marine photovoltaic device, including a frame. Floating components for making the frame float on the sea surface are installed on both sides of the top surface of the frame. A photovoltaic panel 6 is arranged between the two floating components. The photovoltaic panel 6 is installed inside the frame via a bracket 5. A cleaning component for cleaning attached materials is arranged at the bottom of the frame. The frame includes symmetrically arranged crossbeams 1. Mounting blocks 32 are installed at both ends of the crossbeams 1. The two mounting blocks 32 on the same side of the two crossbeams 1 are fixedly connected by side baffles 11. The cleaning component is arranged in the lower part between the two crossbeams 1.

[0026] This invention utilizes a cleaning component located at the bottom of the frame to effectively remove marine organisms such as barnacles, algae, or mollusks, thereby extending the service life of the marine photovoltaic device.

[0027] The design is further optimized by including multiple floats 4, which are mounted on the crossbeam 1. These multiple floats 4 enable the frame to effectively float the photovoltaic panels 6 on the sea surface.

[0028] In a further optimized design, multiple support rods are fixedly connected between the two crossbeams 1, and brackets 5 are mounted on these support rods. Brackets 5 can adjust the tilt angle of the photovoltaic panels 6.

[0029] Multiple support rods enable the bracket 5 to be effectively installed within the frame and to effectively support the photovoltaic panel 6.

[0030] This allows the frame to effectively fit the support 5 and the floating block 4.

[0031] The solution is further optimized. The cleaning component includes two squeezing rollers 31 respectively set at the lower part of the cross frame 1. The two ends of the squeezing rollers 31 are rotatably connected to the mounting block 32 respectively. The two squeezing rollers 31 are set up vertically and mesh with each other. The two squeezing rollers 31 at the bottom are connected by a transmission through an anti-adsorption belt 3. A pressing part is set above the anti-adsorption belt 3.

[0032] The surfaces of the two extrusion rollers 31 located below the same crossbar 1 are serrated. By interlocking the two extrusion rollers 31, barnacles and other adhering substances adsorbed on the surface of the anti-adsorption belt 3 can be squeezed and crushed.

[0033] In a further optimized design, either of the two upper extrusion rollers 31 is connected to a motor 33, and the motor 33 is fixedly connected to the mounting block 32.

[0034] The motor 33 is electrically connected to a storage battery, which is electrically connected to the photovoltaic panel 6 through an inverter. That is, the photovoltaic panel 6 transmits electrical energy to the storage battery through the inverter.

[0035] The direct current (DC) generated by photovoltaic panel 6 needs to be converted to alternating current (AC) by an inverter, and then regulated by a charge controller before being fed into the battery. The inverter plays a crucial role in this process, converting DC into the AC power required by the battery.

[0036] Photovoltaic panel 6: generates direct current through the photovoltaic effect; inverter: converts direct current to alternating current; charging controller: regulates the current direction to prevent overcharging / over-discharging of the battery; battery: stores electrical energy for use on cloudy or rainy days or at night.

[0037] Compared with traditional marine photovoltaic automatic cleaning devices, this invention does not require complicated operating procedures, and its power supply comes directly from photovoltaic power generation, making it self-sufficient.

[0038] The design is further optimized. The pressing part includes a pressure plate 2 that abuts against the top surface of the anti-adsorption belt 3. Multiple connecting strips 21 are fixedly connected to one end of the pressure plate 2 away from the anti-adsorption belt 3. An elastic rod 22 is fixedly connected to one end of the connecting strip 21 away from the pressure plate 2. The two ends of the elastic rod 22 are respectively located on the top surface of the side baffle 11 and are fixedly connected to the side baffle 11.

[0039] The connecting strip 21 ensures that the anti-adsorption strip 3 is effectively positioned between the two side baffles 11.

[0040] The elastic rod 22 above the pressure plate 2 can provide a certain buffer force to the anti-adsorption belt 3 when some stubborn debris cannot be cleaned during the cleaning of the anti-adsorption belt 3 by the pressure plate 2. This absorbs part of the impact force of the pressure plate 2 on the anti-adsorption belt 3, prevents excessive pressure on the anti-adsorption belt 3 during the cleaning process, thereby avoiding damage or wear, helping to protect the anti-adsorption belt 3, reducing the damage that may be caused by direct contact, and protecting the overall structure of the equipment.

[0041] To further optimize the design, arc-shaped corners 23 are provided at both ends of the pressure plate 2 facing the cross frame 1.

[0042] When the arc-shaped corner 23 comes into contact with the anti-adsorption belt 3, the pressure of the pressure plate 2 can be distributed more evenly on the anti-adsorption belt 3, reducing the damage caused by concentrated pressure to the anti-adsorption belt 3. In addition, the arc-shaped contact surface of the arc-shaped corner 23 also reduces the impact force generated by rigid contact, reducing the risk of damage to the anti-adsorption belt 3 and extending the service life of the equipment.

[0043] Meanwhile, when the crushed barnacles are conveyed by the anti-adsorption belt 3 to the support 5 near the photovoltaic panel 6, the pressure plate 2 will scoop up the barnacles and move them to the upper surface of the pressure plate 2, so as to prevent the crushed barnacles from remaining on the anti-adsorption belt 3 and affecting the normal use of the anti-adsorption belt 3.

[0044] The arc-shaped corner 23 of the pressure plate 2 effectively avoids severe wear caused by long-term friction with the anti-adsorption belt 3.

[0045] The design was further optimized by placing the support rod above the elastic rod 22. This facilitates the installation of the bracket 5 and the photovoltaic panel 6.

[0046] In a further optimized design, a cleaning brush 12 is installed between two mounting blocks 32 at both ends of the cross frame 1, and the cleaning brush 12 is fixedly connected to the bottom of the cross frame 1.

[0047] The end of the cleaning brush 12 away from the crossbar 1 abuts against the anti-adhesion strip 3.

[0048] The cleaning brush 12 can perform a simple cleaning of the barnacles on the surface of the anti-adsorption belt 3 before transporting them to the two squeezing rollers 31, reducing the burden of subsequent processing. This can effectively reduce the interference of the attached materials (such as long algae) on subsequent mechanical processing (such as the crushing by the two squeezing rollers 31) and improve the overall cleaning effect.

[0049] In a further optimized design, the cleaning brush 12 is positioned at the lower part of one end of each of the two crossbars 1, which are opposite to each other. That is, the anti-adhesion strip 3 is positioned between the two cleaning brushes 12, enabling the cleaning brushes 12 to effectively and simply clean the deposits on the surface of the anti-adhesion strip 3.
