Description

Technical Field

[0001] This invention relates to the field of photovoltaic panel cleaning equipment technology, specifically a mobile photovoltaic panel cleaning device. Background Technology

[0002] With the global energy structure shifting towards clean energy, the photovoltaic (PV) industry has experienced explosive growth, with large-scale PV power plants and distributed PV systems being widely deployed across various regions, and the number and coverage area of ​​PV panels continuing to climb. During long-term operation, PV panels easily accumulate natural pollutants such as dust, sand, bird droppings, and leaves. These deposits block sunlight, reducing the light transmittance of the PV panels and thus affecting photoelectric conversion efficiency, directly impacting the power generation and economic benefits of PV projects. Especially in areas with frequent sandstorms, high humidity, or severe air pollution, pollutants accumulate even faster, making the need for PV panel cleaning and maintenance even more urgent. To ensure that PV systems maintain efficient operation, regular cleaning of PV panels has become an indispensable part of the daily operation and maintenance of PV power plants, providing a practical basis and broad space for the research and development and application of mobile PV panel cleaning devices.

[0003] The mobile photovoltaic panel cleaning device mainly consists of a moving module, a cleaning execution module, a power and control module, and an auxiliary adapter module. The moving module adopts a tracked or wheeled walking mechanism and is equipped with an adjustable lifting bracket to adapt to photovoltaic panel arrays at different tilt angles. The cleaning execution module includes a rotating brush assembly, a high-pressure spray assembly, and a water-absorbing scraper. The brushes are made of soft and wear-resistant nylon and can adaptively adjust the contact force. The spray assembly is equipped with filtered clean water or special cleaning agent nozzles, and the water-absorbing scraper can remove residual water. Its working principle is based on a "movement-cleaning-linkage" collaborative mechanism. After startup, the control module drives the moving module to move at a constant speed along the photovoltaic panel arrangement direction. When it reaches the cleaning area, the cleaning execution module first sprays water or cleaning agent through the spray assembly to soften the contaminants, and then the rotating brush assembly scrubs and removes the stains. The power module provides stable drive, and sensors monitor in real time to ensure efficient cleaning without damaging the photovoltaic panels, realizing continuous and automated cleaning of large-area photovoltaic panels.

[0004] Currently, some mobile photovoltaic panel cleaning devices often experience problems such as reduced operational stability and traction due to the accumulation of impurities on the moving tracks. Furthermore, they are difficult to effectively buffer the impact force when subjected to impacts on the side of the device, which can easily lead to damage to the device or photovoltaic panels, or even cause the device to break off from the photovoltaic panels due to loss of control.

[0016] This invention provides a mobile photovoltaic panel cleaning device. It has the following beneficial effects: 1. This invention achieves initial cleaning by using a drive motor to move the rotating wheel and moving track on the photovoltaic panel during operation of the cleaning device. Simultaneously, a spray frame sprays water, and a second motor drives a rolling brush to scrape the photovoltaic panel. When the rotating wheel rotates, the guide block intermittently pushes the fixed column, causing the inner plate to slide outward and stretching the telescopic column. After the guide block disengages, the telescopic column pulls the inner plate back to its original position, causing the inner plate to slide back and forth, driving the cleaning brush to scrape the moving track, preventing impurities from accumulating and affecting operation while maintaining grip. When the device is impacted on the side, a spring compresses to buffer the impact force, and the fixed column squeezes the guide block to slow down or stop the device, reducing damage to the device and photovoltaic panel and preventing the device from running out of control and crashing off the photovoltaic panel.

[0017] 2. During the cleaning operation of the device, the invention starts the motor to drive the rotating disk to rotate, which drives the guide column to slide within the sliding frame, causing the sliding frame to slide back and forth within the limit block. The connecting rod 2 drives the sliding frame 2 to slide back and forth within the fixed frame 2, causing the cleaning scraper to scrape the photovoltaic panel to remove stubborn stains. At the same time, the telescopic column 2 continuously pushes the cleaning scraper to slide within the sliding frame 2, ensuring that the cleaning scraper is always in contact with the surface of the photovoltaic panel, ensuring the cleaning effect and improving the cleaning quality.

[0018] 3. In this invention, when the sliding frame 1 slides back and forth within the limiting block, the connecting rod 1 drives the fixed rod to move, causing the fixed frame 1 to slide within the sliding groove via the sliding block to achieve reciprocating swing, thereby driving the spray frame to move back and forth and achieving reciprocating water spray; this method can cover a larger area with less water, and the impact of the swinging water flow can loosen stubborn stains, creating favorable conditions for subsequent cleaning and improving the overall cleaning effect.

Please see the appendix Figure 5 Appendix Figure 7 and attached Figure 8The spraying mechanism 3 includes two sliding blocks 34, which are externally slidably connected to the inside of the support frame 5. The sliding blocks 34 can slide within the support frame 5, driving the fixed frame 33 to move. The fixed frame 33 is fixedly connected inside the sliding blocks 34. A fixed rod 32 is fixedly connected to the rear end of the fixed frame 33. The fixed frame 33 provides installation support for the spraying frame 36. The fixed rod 32 can connect the fixed frame 33 and the connecting rod 31 to transmit power. The connecting rod 31 is fixedly connected to the rear end of the fixed rod 32. The spraying frame 36 is fixedly connected to the front end of the fixed frame 33. The connecting rod 31 can transmit the power of the sliding frame 44 to the fixed rod 32, and the spraying frame 36 can spray water onto the photovoltaic panel. The rear end of the connecting rod 31 is fixedly connected to the front end of the sliding frame 44. The support frame 5 has a sliding groove 35 inside to ensure that the sliding frame 44 can drive the spraying mechanism 3 through the connecting rod 31. The sliding groove 35 provides sliding space for the sliding block 34 to ensure its smooth movement.

[0023] Working Principle: When cleaning the photovoltaic panels, the drive motor inside the housing 1 causes the rotating wheel 27 to move the moving track 28, thus moving the entire device over the top of the photovoltaic panels. Simultaneously, the spray frame 36 sprays water onto the photovoltaic panels, and the motor 9 drives the rolling brush 6 to scrape the surface of the photovoltaic panels, achieving a cleaning effect. As the rotating wheel 27 rotates, the guide block 26 intermittently pushes the fixed column 25, causing the inner plate 22 to slide outwards towards the outer plate 21. At this time, the telescopic column 23 is stretched, generating tension. When the guide block 26 releases pressure on the fixed column 25, the telescopic column 23 automatically pushes the inner plate 22 inwards towards the outer plate 21. The inner plate 22 slides back and forth inside the outer plate 21, causing the fixed block 291 to drive the cleaning brush 292 to scrape the outside of the moving track 28, thus cleaning the moving track 28 and preventing the accumulation of impurities on the moving track 28 from affecting the overall operation of the device. It also maintains good grip. At the same time, when the side of the device is subjected to a hard impact, the spring 24 will be compressed, thereby offsetting and weakening the impact force and reducing the damage to the device body and photovoltaic panel caused by the side collision. Meanwhile, the fixed column 25 will hard squeeze the guide block 26, so that the device will automatically decelerate or stop after the collision, which can effectively prevent the device from rushing out of the photovoltaic panel or causing more serious damage due to loss of control.

[0024] When the device is cleaning, motor 41 can be started, which drives the rotating disk 42 to rotate. The rotation of the rotating disk 42 causes the guide column 43 to slide inside the sliding frame 44, so that the outside of the sliding frame 44 slides back and forth inside the limiting block 410. The sliding of the limiting block 410 will drive the sliding frame 46 to slide back and forth inside the fixed frame 47 through the connecting rod 45. This allows the cleaning scraper 48 to scrape the top of the photovoltaic panel to remove stubborn stains and improve the cleaning effect. At the same time, the telescopic column 491 will continuously push the cleaning scraper 48 to slide inside the sliding frame 46, so that the cleaning scraper 48 will continuously contact the surface of the photovoltaic panel and ensure the cleaning effect.

[0025] When the sliding frame 44 slides back and forth inside the limiting block 410, it moves the fixed rod 32 along with the connecting rod 31. This causes the fixed frame 33 to slide along with the sliding block 34 inside the sliding groove 35, achieving the effect of the fixed frame 33 swinging back and forth. Ultimately, the spray frame 36 moves back and forth with the fixed frame 33, achieving the effect of water spraying back and forth. This allows for covering a larger area with less water and loosens stubborn stains through the impact of the swinging water flow, improving the subsequent cleaning effect.
