Description

Technical Field

[0001] The present disclosure relates to the field of solar power generation technology, and in particular to a solar panel cleaning device. The present disclosure also relates to a solar power station using the solar panel cleaning device. Background Art

[0002] With the global energy transition and increasing concerns about environmental sustainability, the demand for renewable energy is rapidly growing. Solar energy, as a renewable energy source, has become one of the most sought-after energy sources due to its clean, unlimited, and renewable nature. Among the various applications of solar energy, solar power generation technology is particularly important due to its ability to directly convert solar energy into electricity. As the core component of this technology, the performance of solar panels directly affects power generation efficiency, which in turn affects the effective utilization of solar energy.

[0003] However, in practical applications, using solar panels to generate electricity faces environmental challenges: pollutants such as dust, bird droppings, and hail can adhere to the panels, reducing their photoelectric conversion efficiency and, in turn, affecting overall power generation efficiency. Therefore, ensuring the cleanliness of solar panel surfaces is crucial to maintaining efficient operation.

[0004] Currently, solar panels are cleaned primarily through manual and mechanical cleaning. Manual cleaning typically involves workers using tools to physically clean the panels. This method suffers from low efficiency, inconsistent cleaning results, and significant labor costs. While mechanical cleaning can improve cleaning efficiency, it requires expensive equipment and maintenance. Furthermore, in areas with water scarcity or cold climates, conventional water-intensive cleaning techniques are unavailable, necessitating the use of dry cleaning techniques, which often struggle to match the effectiveness of conventional water-based cleaning techniques.

[0005] U.S. Patent No. 8771432 B2 discloses a solar panel cleaning system and method, including a solar panel cleaning system, which includes a cleaning component and a guide component that drives the cleaning component to move on the solar panel. The cleaning component includes a rotating cleaning device with flexible fins installed thereon, an air flow generating device, and a driving component. When the cleaning system is working, the driving component drives the cleaning system to move along the solar panel, and the air flow generating device in the cleaning component generates a directional airflow to push the dust on the solar panel downward and away from the solar panel. The rotating cleaning device is arranged behind the air flow generating device, and when the cleaning system is working, it rotates and drives the flexible fins to contact the solar panel, thereby sweeping away dirt and dust on the solar panel. However, cleaning by airflow is not effective for cleaning pollutants adhering to the solar panel, such as bird droppings, and there are gaps between the fins of the rotating cleaning device, which cannot completely cover the area of ​​the solar panel, resulting in poor cleaning effect.

[0006] Therefore, a dry cleaning device is needed whose cleaning range can completely cover the solar panel. Utility Model Content

[0007] A technical problem to be solved by the present disclosure is how to completely clean the surface of a solar panel by dry cleaning.

[0008] To address the aforementioned technical issues, the first aspect of the present disclosure provides a solar panel cleaning device, comprising a frame, a travel module disposed outside the bottom of the frame, a roller brush module disposed at the bottom of the frame and partially protruding therefrom, an air knife module disposed at the bottom of the frame, and a dust-binding module disposed within the frame. The dust-binding module comprises first and second pressure rollers disposed on the same horizontal plane, and a dust-binding film pressed beneath it by the first and second pressure rollers.

[0009] In some embodiments, the dust sticking module further includes a film placing roller and a film collecting roller arranged higher than the first pressure roller and the second pressure roller, and both ends of the dust sticking film are respectively connected to the film placing roller and the film collecting roller.

[0010] In some embodiments, the dust-binding module further includes a film-collecting motor disposed on the frame and transmission-connected to the film-collecting roller.

[0011] In some embodiments, the dust sticking module further includes a lifting cylinder which is transmission-connected to the first pressure roller and the second pressure roller respectively, and the lifting cylinder can drive the first pressure roller and the second pressure roller to extend out of the lower surface of the frame.

[0012] In some embodiments, the walking module includes a walking guide wheel and a walking motor connected to the walking guide wheel.

[0013] In some embodiments, the roller brush module includes at least one roller brush arranged at the bottom of the frame and extending out of the frame, a motor mounting base arranged on the frame, a roller brush motor mounted on the motor mounting base, and a coupling that connects the roller brush and the roller brush motor.

[0014] In some embodiments, the air knife module includes at least one air knife disposed at the bottom of the rack for delivering air flow to the lower part of the rack.

[0015] In some embodiments, the roller brush module, the air knife module and the mucosa module are arranged in sequence in the direction of advancement of the walking module.

[0016] In a second aspect, an embodiment of the present disclosure further provides a solar power station using the above-mentioned solar panel cleaning device.

[0017] In some embodiments, the solar power station includes a photovoltaic substrate, the solar panel cleaning device is disposed above the photovoltaic substrate, and the length of the sticky film provided in the solar panel cleaning device is greater than the width of the photovoltaic substrate.

[0018] Through the above technical solution, the solar panel cleaning device provided by the present disclosure cleans the solar panel through the roller brush module, wind knife module and dust sticking module thereon, and moves on the surface of the solar panel that needs to be cleaned through the walking module. When the solar panel cleaning device is working, the dust sticking film is pressed flatly on the solar panel by the first pressure roller and the second pressure roller, which can stick fine dust and stains thereon, and moves with the movement of the entire solar panel cleaning device, so that the solar panel that has not been cleaned by the dust sticking module contacts the unused dust sticking film to complete the cleaning of the entire solar panel. Through the dust sticking film covering the entire solar panel in the dust sticking module, the solar panel cleaning device of the present disclosure can completely clean the entire solar panel, thereby ensuring the cleanliness of the solar panel, and then ensuring the power generation efficiency of the solar panel, and the dust sticking module and the entire solar panel cleaning device use a dry cleaning method without the use of water, so that it can be used in a variety of environments without consuming water resources, and has strong applicability.

[0031] All terms used in this disclosure have the same meaning as understood by one of ordinary skill in the art to which this disclosure belongs, unless otherwise specifically defined. It should also be understood that terms defined in, for example, common dictionaries should be interpreted as having a meaning consistent with their meaning in the context of the relevant art, and should not be interpreted in an idealized or highly formal sense, unless explicitly defined as such herein.

[0032] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0033] A first aspect of the present disclosure provides a solar panel cleaning device 2, such as Figure 1 As shown, the machine comprises a frame 201, a traveling module disposed outside the bottom of the frame 201, a roller brush module disposed at the bottom of the frame 201 and partially protruding from the bottom of the frame 201, an air knife module disposed at the bottom of the frame 201, and a dust-binding module disposed inside the frame 201. The dust-binding module comprises a first pressing roller 207 and a second pressing roller 208 disposed on the same horizontal plane, and a dust-binding film pressed beneath the first pressing roller 207 and the second pressing roller 208.

[0034] The solar panel cleaning device 2 cleans the solar panel through the roller brush module, wind knife module and dust sticking module thereon, and moves on the surface of the solar panel that needs to be cleaned through the walking module. When the solar panel cleaning device is working, the dust sticking film is pressed flatly on the solar panel by the first pressure roller 207 and the second pressure roller 208, which can stick fine dust and stains to it, and moves with the movement of the entire solar panel cleaning device 2, so that the solar panel that has not been cleaned by the dust sticking module comes into contact with the unused dust sticking film to complete the cleaning of the entire solar panel. Through the dust sticking film covering the entire solar panel in the dust sticking module and the display module, the solar panel cleaning device disclosed in the present invention can completely clean the entire solar panel, thereby ensuring the cleanliness of the solar panel and further ensuring the power generation efficiency of the solar panel, and the dust sticking module and the entire solar panel cleaning device 2 use a dry cleaning method without the use of water, so that it can be used in a variety of environments without consuming water resources, and has strong applicability.

[0035] The roller brush module can be used to brush the surface of the solar panel to be cleaned, removing dust and stuck-on stains. The air knife module can be used to blow air across the surface of the solar panel to remove dirt. By combining the air knife module, roller brush module, and dust sticking module, the vast majority of dust, stains, and contaminants on the solar panel can be removed, ensuring that the surface cleanliness of the solar panel reaches the required level for power generation, thereby ensuring that the power generation efficiency of the solar power generation system using it meets the required standards.

[0036] In some embodiments, as Figure 1 As shown, the dust-sticking module also includes a film-laying roller 203 and a film-taking-up roller 204, which are arranged higher than the first pressure roller 207 and the second pressure roller 208. The ends of the sticky film are connected to the film-laying roller 203 and the film-taking-up roller 204, respectively. The sticky film is unwound and rewound by the film-laying roller 203 and the film-taking-up roller 204, respectively. When the solar panel cleaning device 2 is in operation, the first pressure roller 207 and the second pressure roller 208 press the sticky film onto the solar panel. As the solar panel cleaning device 2 moves, the sticky film also moves, driving the film-laying roller 203 to rotate, thereby releasing the sticky film that has not contacted the solar panel surface, and driving the film-taking-up roller 204 to rotate, rolling the used sticky film onto the film-taking-up roller 204. Through the film-releasing roller 203 and the film-collecting roller 204, a large amount of sticky film can be provided for the sticky module for use, and a storage method is provided for the used sticky film, thereby ensuring that the solar panel cleaning device 2 can clean a solar panel of a certain area and can be used for a long time without the need for frequent manual replacement and replenishment of the sticky film.

[0037] In some embodiments, as Figure 1 and Figure 2 As shown, the dust-binding module also includes a film-collecting motor 210 mounted on the frame 201 and drivingly connected to the film-collecting roller 204. When the solar panel cleaning device 2 is in operation, the film-collecting motor 210 drives the film-collecting roller 204 to rotate, allowing it to roll the used sticky film onto the film-collecting roller 204. By driving the film-collecting roller 204, the film-collecting motor 210 ensures that the used sticky film is smoothly rolled onto the film-collecting roller 204, thereby ensuring that the sticky film that contacts the solar panel is unused sticky film. This, in turn, ensures that the dust-collecting module can use the sticky film to remove dust and stains from the solar panel, effectively cleaning the solar panel.

[0038] In some embodiments, as Figure 1 As shown, the dust sticking module further includes a lifting cylinder 205 that is transmission-connected to a first pressure roller 207 and a second pressure roller 208, respectively. The lifting cylinder 205 is capable of driving the first and second pressure rollers 207 and 208 to extend from the lower surface of the frame 201. The lifting cylinder 205 may be a pneumatic cylinder. When the solar panel cleaning device 2 is in operation, the lifting cylinder 205 is capable of driving the first and second pressure rollers 207 and 208 to move upward and downward. This allows the sticky film to be pressed by the first and second pressure rollers 207 and 208 to extend from the frame 201 and be completely pressed against the solar panel when the sticky film needs to contact and clean the solar panel. When the dust sticking module stops operating and the sticky film no longer needs to contact the solar panel, it can be retracted into the frame 201 to prevent it from adhering to other objects. The lifting cylinder 205 can control the downward pressure of the first pressing roller 207 and the second pressing roller 208, thereby controlling the pressure with which the sticky film is pressed onto the solar panel. This allows the solar panel cleaning device 2 to be adapted to various solar panels and working environments when cleaning different solar panels and the stains thereon.

[0039] In some embodiments, the lifting cylinder 205 may also be an electric cylinder connected to a drive motor. By using an electric cylinder as the lifting cylinder 205, the pressing pressure applied by the lifting cylinder 205 to the first pressing roller 207 and the second pressing roller 208 can be precisely controlled. Furthermore, the lifting cylinder 205 can be remotely controlled by connecting to the electric cylinder, thereby facilitating the regulation of the lifting cylinder 205 so that the dust-binding module can remove dust and dirt from the solar panel.

[0040] In some embodiments, as Figure 1 and Figure 3As shown, the travel module includes a travel guide wheel 206 and a travel motor 214 connected thereto. When the solar panel cleaning device 2 is in operation, the travel guide wheel 206 mounted below the frame 201 is driven by the travel motor 214 to rotate and drive the solar panel cleaning device 2 to move over the solar panel, allowing the solar panel cleaning device 2 to clean various locations on the solar panel.

[0041] In some embodiments, as Figure 1 、 Figure 2 and Figure 3 As shown, the roller brush module includes at least one roller brush 209 disposed at the bottom of a frame 201 and extending outward from the frame 201, a motor mount 212 disposed on the frame 201, a roller brush motor 211 mounted on the motor mount 212, and a coupling 213 that connects the roller brush 209 and the roller brush motor 211. When the solar panel cleaning device 2 is in operation, the roller brush 209 extending from the bottom of the frame 201 in the roller brush module can contact the solar panel and, driven by the roller brush motor 211, rotate to clean the surface of the solar panel. The roller brush 209 can remove larger dirt and stains protruding from the solar cells, thereby cleaning the solar panel. The motor mount 212 and roller brush motor 211 disposed within the frame 201 ensure that the roller brush motor 211 is protected from water or dust in adverse conditions such as rain and malfunction. This ensures that the solar panel cleaning device 2 can operate in a variety of environments. The coupling 213 can compensate for any deviation between the roller brush 209 and the transmission shaft of the roller brush motor 211. At the same time, it can also effectively transmit the power when the solar panel cleaning device 2 vibrates in strong winds and other conditions, ensuring that the roller brush 209 can work, thereby enabling the solar panel cleaning device 2 to work in a variety of conditions.

[0042] In some embodiments, the roller brush 209 can be replaced with a disc brush. By using a disc brush, the surface of the solar panel within the brush's coverage area can be cleaned more comprehensively, thereby avoiding the situation where the roller brush 209 may not reach part of the solar panel due to the structure of the roller brush 209.

[0043] In some embodiments, as Figure 1As shown, the air knife module includes at least one air knife 202 disposed at the bottom of a frame 201 for delivering airflow to the lower portion of the frame 201. The side of the air knife 202 may have an interface for connecting to a high-pressure blower. The air knife 202 may have an interior cavity that tapers downward toward the lower portion of the frame 201. The end of the cavity may be connected to an opening, which may be a rectangular opening with an area equal to the area of ​​the end of the tapered cavity and a length equal to the length of the solar panel. When the solar panel cleaning device 2 is in operation, the high-pressure blower connected to the air knife 202 blows high-pressure air into the air knife 202. The air knife 202 further increases the air velocity and changes its direction, blowing it toward the solar panel at a certain angle. This allows the high-pressure air to generate a sweeping force on the surface of the solar panel, thereby removing dust and dirt from it. The air knife module and the air knife 202 therein can clean the surface of the solar panel by blowing. In conjunction with the walking module, this ensures that the entire solar panel is cleaned without leaving any blind spots.

[0044] In some embodiments, as Figure 1 As shown, the roller brush module, the air knife module, and the mucosa module are arranged in sequence in the direction of the travel module. When the solar panel cleaning device 2 is in operation, driven by the travel module, the surface of the solar panel that has not been cleaned will first be cleaned by the roller brush module to remove large pieces of dirt and stains adhering to the solar panel. The air knife module will then be used to blow and clean the dirt and stains remaining on the surface of the solar panel after being cleaned by the roller brush module. Finally, the mucosa module will use the mucosa to clean the stains and fine dust that are close to the surface of the solar panel and cannot be removed by the roller brush module and the air knife module. The above cleaning sequence can ensure that all kinds of stains on the solar panel can be completely cleaned, and can ensure that the sticky film will not be contaminated with too much dust and dirt, resulting in the thickness of the sticky film rolled on the film roller 204 being too thick to affect the normal operation of other components in the frame 201.

[0045] Secondly, embodiments of the present disclosure further provide a solar power plant utilizing the aforementioned solar panel cleaning device 2. By utilizing the solar panel cleaning device 2, the surfaces of the solar panels in the solar power plant can be kept clean, thereby ensuring that the solar power plant maintains a high level of power generation efficiency under various environments.

[0046] In some embodiments, as Figure 4As shown, the solar power station includes a photovoltaic substrate 1, and a solar panel cleaning device 2 is disposed above the photovoltaic substrate 1. The sticky film provided in the solar panel cleaning device 2 is longer than the width of the photovoltaic substrate 1. When the solar panel cleaning device 2 is in operation, the sticky film, which is longer than the width of the photovoltaic substrate 1, allows the solar panel cleaning device 2 to clean all locations on the surface of the photovoltaic substrate 1 by simply moving from one end of the photovoltaic substrate 1 to the other, greatly improving the operating efficiency of the solar panel cleaning device 2.

[0047] Thus far, various embodiments of the present disclosure have been described in detail. To avoid obscuring the concept of the present disclosure, some details known in the art have not been described. Based on the above description, those skilled in the art can fully understand how to implement the technical solutions disclosed herein.
