Description

Technical Field

[0001] This utility model relates to the field of floating photovoltaic panel technology, specifically a cleaning device for floating photovoltaic panels. Background Technology

[0002] Photovoltaic panels, also known as solar photovoltaic modules, are the core energy conversion components of solar power generation systems. They directly convert solar radiation energy into electrical energy through the photoelectric effect and are widely used in ground-mounted photovoltaic power stations, floating photovoltaic power stations, building-integrated photovoltaics, distributed photovoltaic power generation, and other scenarios. They are a key carrier for the utilization of clean energy.

[0003] Photovoltaic panels are widely used in both hydroelectric and land-based power plants. Their core function is to convert solar energy into photovoltaic power. However, since photovoltaic panels are exposed to the elements for extended periods, their surfaces easily accumulate dust, bird droppings, algae, and other pollutants. If not cleaned promptly, these pollutants can block light, severely affecting the panel's light transmittance and light absorption efficiency, ultimately leading to a decrease in power generation. Currently, the mainstream method for cleaning photovoltaic panels is to directly scrub them with a brush. However, this method has significant limitations. On the one hand, brushes cannot reach the crevices or stubborn stains on the panel's surface, resulting in incomplete cleaning. On the other hand, dry brushing or uneven cleaning pressure can leave pollutants or scratch the panel's surface, failing to fundamentally guarantee the cleaning effect and the long-term safety of the photovoltaic panels. Utility Model Content

[0004] The purpose of this invention is to provide a cleaning device for floating photovoltaic panels to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cleaning device for floating photovoltaic panels, comprising a photovoltaic panel body and mounting legs fixed at the four corners of the bottom of the photovoltaic panel body, and further comprising:

[0006] Positioning shells are fixed to both sides of the photovoltaic panel body. An operating shell is provided on one side of the top of the photovoltaic panel body. The inner cavity of one side of the operating shell is provided with a cleaning component that facilitates simultaneous sweeping and rinsing of the photovoltaic panel body. The cleaning component includes a water pump, and transmission rollers are rotatably connected to both sides of the inner wall of the operating shell through bearings.

[0007] Preferably, a water supply pipe is connected to a flange on one side of the water pump, the surface of the water supply pipe is connected to the flange of the transmission roller, and the surface of the transmission roller is provided with multiple water outlet holes.

[0008] Preferably, a water pump is connected to a suction pipe via a flange on one side, and a filter cylinder is fixedly connected to the bottom of the suction pipe on one side.

[0009] Preferably, the inner cavity of the positioning shell is provided with a roller, an auxiliary rod is rotatably connected to one side of the roller, an auxiliary groove is slidably connected to the surface of the auxiliary rod, and the auxiliary groove is opened on the inner wall of the positioning shell.

[0010] Preferably, a motor is fixedly connected to one side of the operating housing, and a rotating rod is fixedly connected to the output shaft of the motor, with one side of the rotating rod fixedly connected to the transmission roller.

[0011] Preferably, a first transmission wheel is fixedly connected to the surface of the rotating rod, a transmission belt is meshed with the surface of the first transmission wheel, a second transmission wheel is meshed with the inner cavity at the bottom of the transmission belt, and one side of the second transmission wheel is rotatably connected to a roller therein.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This invention, through its cleaning component, allows the motor-driven transmission roller to rotate while simultaneously driving the brushes on its surface to perform preliminary cleaning of the photovoltaic panel. During this process, a water pump is simultaneously activated, drawing water from the lake through a pumping pipe. The filter cartridge at the bottom of the pumping pipe filters impurities in the water, preventing blockage of the pipes and water outlets. The filtered clean water is then transported through a water supply pipe to the inside of the transmission roller, where it forms a fine spray through multiple evenly spaced water outlets on its surface. This spray wets the surface of the photovoltaic panel and the brushes on the transmission roller. The rotating transmission roller not only removes stubborn stains with the brushes but also carries away dust and residual dirt with the help of the water flow, resulting in a more thorough cleaning effect while avoiding the wear and tear on the surface of the photovoltaic panel caused by dry brushing.

[0021] 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.

[0022] Please see Figure 1 - Figure 4 As shown, a cleaning device for floating photovoltaic panels includes a photovoltaic panel body 1 and mounting legs 2 fixed to the four corners of the bottom of the photovoltaic panel body 1, and further includes:

[0023] Positioning shells 3 are fixed on both sides of the photovoltaic panel body 1. An operation shell 4 is provided on one side of the top of the photovoltaic panel body 1. A cleaning component 5 is provided in the inner cavity of one side of the operation shell 4 to facilitate cleaning and rinsing of the photovoltaic panel body 1. The cleaning component 5 includes a water pump 501, and transmission rollers 6 are rotatably connected to both sides of the inner wall of the operation shell 4 through bearings.

[0024] A water pump 501 has a flange on one side connected to a water supply pipe 502. The surface of the water supply pipe 502 is connected to the flange of the transmission roller 6, and the surface of the transmission roller 6 is provided with multiple water outlet holes 7. A water pump 501 has a flange on one side connected to a water suction pipe 503, and a filter cylinder 504 is fixedly connected to the bottom of one side of the water suction pipe 503. A roller 8 is provided in the inner cavity of the positioning shell 3. An auxiliary rod 9 is rotatably connected to one side of the roller 8. An auxiliary groove 10 is slidably connected to the surface of the auxiliary rod 9, and the auxiliary groove 10 is opened on the inner wall of the positioning shell 3. First, the motor 11 is started. The output shaft of the motor 11 drives the rotating rod 12 to rotate. On the one hand, it drives the transmission roller 6 to rotate synchronously. While the transmission roller 6 is rotating, it drives the brush on the surface of the transmission roller 6 to contact the photovoltaic panel body 1. On the other hand, through the rotating rod The linkage between the first drive wheel 13, the drive belt 14 and the second drive wheel 15 on 12 drives the roller 8 to rotate, so that the operating shell 4 moves smoothly along the surface of the photovoltaic panel body 1. During this process, the water pump 501 starts synchronously and draws water from the lake through the water pumping pipe 503. The filter cylinder 504 at the bottom of the water pumping pipe 503 can filter impurities in the water to avoid clogging the pipe and the water outlet 7. The filtered clean water is transported to the inside of the drive roller 6 through the water supply pipe 502, and then forms a fine spray through multiple water outlets 7 evenly opened on its surface to wet the brushes on the surface of the photovoltaic panel and the surface of the drive roller 6. The rotating drive roller 6 not only removes stubborn stains through the brushes, but also carries away dust and residual dirt with the help of water flow, making the cleaning effect more thorough, while avoiding the wear of the photovoltaic panel surface by dry brushing.

[0025] A motor 11 is fixedly connected to one side of the operating housing 4. A rotating rod 12 is fixedly connected to the output shaft of the motor 11, and one side of the rotating rod 12 is fixedly connected to a transmission roller 6. A first transmission wheel 13 is fixedly connected to the surface of the rotating rod 12. A transmission belt 14 is meshed with the surface of the first transmission wheel 13. A second transmission wheel 15 is meshed with the inner cavity at the bottom of the transmission belt 14, and one side of the second transmission wheel 15 is rotatably connected to a roller 8 therein. Power generation panels 16 are fixedly connected to both sides of the top of the operating housing 4, and a sensor 17 is fixedly connected to the top of the operating housing 4. Support rods 18 are fixedly connected to both sides of the bottom of the operating housing 4. Limiting grooves 19 are fixedly connected to the surface of the support rods 18, and the limiting grooves 19 are located at the top of the positioning housing 3. When cleaning the photovoltaic panel body 1 is required, the motor 11 is first started. The output shaft of the motor 11 drives the rotating rod 12 to rotate. The rotating rod 12 rotates in tandem with the power generation panel. The drive roller 6 and the brush on its surface are fixedly connected to the step drive and rotate. At the same time, the first drive wheel 13 on the surface of the rotating rod 12 drives the second drive wheel 15 meshing at the bottom to rotate synchronously through the drive belt 14. The second drive wheel 15 then drives the corresponding roller 8 to rotate, so that the operating shell 4 moves smoothly along the surface of the photovoltaic panel body 1. The power generation plate 16 on the top of the operating shell 4 can absorb solar energy in real time and convert it into electrical energy to provide continuous power for components such as the motor 11 and sensor 17. It is suitable for outdoor operation scenarios without external power supply, and is energy-saving and environmentally friendly. The sensor 17 detects the adhesion of pollutants on the surface of the photovoltaic panel and the operating position of the device in real time. When the pollutant concentration is detected to reach the preset threshold, the cleaning program is automatically triggered. When the device moves to the edge of the photovoltaic panel, it can feed back a signal to control the roller 8 to rotate in reverse, so as to achieve reciprocating cleaning, thus completing the cleaning of the photovoltaic panel without manual intervention.

[0026] Working principle: First, the device is installed on the water surface. Then, the water pumping pipe 503 is placed in the water, and the filter cartridge 504 is used to intercept impurities in the water. At this time, the motor 11 is started. The output shaft of the motor 11 drives the rotating rod 12 to rotate. The rotating rod 12 synchronously drives the transmission roller 6 and the brush on its surface to rotate. At the same time, the first transmission wheel 13 on the surface of the rotating rod 12 drives the second transmission wheel 15 meshing at the bottom to rotate synchronously through the transmission belt 14. The second transmission wheel 15 then drives the corresponding roller 8 to rotate, so that the operating shell 4 moves smoothly along the surface of the photovoltaic panel body 1. During this process, the water pump 501 starts simultaneously, drawing water from the lake through the water pumping pipe 503. The filter cylinder 504 at the bottom of the water pumping pipe 503 can filter impurities in the water, preventing blockage of the pipe and the water outlet 7. The filtered clean water is transported to the inside of the transmission roller 6 through the water supply pipe 502, and then forms a fine spray through multiple water outlets 7 evenly opened on its surface, wetting the surface of the photovoltaic panel and the brushes on the surface of the transmission roller 6. The rotating transmission roller 6 not only removes stubborn stains through the brushes, but also carries away dust and residual dirt with the help of water flow, resulting in a more thorough cleaning effect, while avoiding the wear and tear on the surface of the photovoltaic panel caused by dry brushing.

[0027] It should be noted that the power generation plate 16 on the top of the operating shell 4 can absorb solar energy in real time and convert it into electrical energy to provide continuous power for components such as the motor 11 and sensor 17. It is suitable for outdoor operation scenarios without external power supply, and is energy-saving and environmentally friendly. The sensor 17 detects the adhesion of pollutants on the surface of the photovoltaic panel and the operating position of the device in real time. When the pollutant concentration reaches the preset threshold, the cleaning program is automatically triggered. When the device moves to the edge of the photovoltaic panel, it can send a feedback signal to control the roller 8 to rotate in reverse, so as to achieve reciprocating cleaning. Thus, the photovoltaic panel can be cleaned without manual intervention.
