Description

[0002] Ensuring efficient system operation is crucial during the operation and maintenance of photovoltaic panels. This is especially true in areas prone to strong winds and frequent sandstorms. These adverse weather conditions often result in large amounts of sand, dust, and other fine particles clinging to the surfaces of photovoltaic panels. These deposits not only block direct sunlight from reaching the photovoltaic cells, reducing their effective absorption of light energy, but also increase the operating temperature of the panels due to the heat absorption of the dust, further reducing photoelectric conversion efficiency.

[0003] Therefore, to maintain the power generation capacity and economic benefits of a photovoltaic power plant, regular cleaning of photovoltaic panels is essential. Cleaning not only removes surface dust and dirt, restoring the panels' maximum ability to absorb sunlight, but also helps reduce the operating temperature of the panels, improving their overall power generation efficiency.

[0030] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0031] The following describes a cleaning vehicle 100 according to an embodiment of the present invention with reference to the accompanying drawings.

[0032] Reference Figures 1-4 According to the first embodiment of the present invention, a cleaning vehicle 100 includes a cleaning mechanism 1, a pressure sensor, a movable arm 3, and a mobile carrier. The cleaning mechanism 1 includes a support body 11, a cleaning roller brush 12, a water-sweeping roller brush 13, and an elastic member 14. The cleaning roller brush 12 and the water-sweeping roller brush 13 are both arranged on the support body 11. The cleaning roller brush 12 and the water-sweeping roller brush 13 are arranged side by side. The cleaning roller brush 12 is used to clean photovoltaic panels.

[0033] For example, refer to Figure 2 and Figure 3 The cleaning roller brush 12 may include a cleaning drive member, a cleaning shaft 124 and a brush 125. The brush 125 extends radially along the cleaning shaft 124 and covers the radial outer surface of the cleaning shaft 124. The cleaning drive member is connected to the cleaning shaft 124. The cleaning drive member is used to drive the cleaning shaft 124 to rotate, so as to drive the brush 125 to sweep away dust on the surface of the photovoltaic panel. When cleaning the photovoltaic panel, the cleaning shaft 124 is spaced apart from the photovoltaic panel, and the brush 125 stops at the surface of the photovoltaic panel and undergoes a certain deformation. This can prevent the cleaning shaft 124 from crushing the photovoltaic panel, and the dust on the surface of the photovoltaic panel can be cleaned by the brush 125.

[0034] The elastic member 14 is connected between the sweeping roller brush 13 and the bracket body 11 , and is used to apply pressure to the sweeping roller brush 13 to stop the sweeping roller brush 13 against the photovoltaic panel; for example, the elastic member 14 can be a spring or a rubber member.

[0035] The pressure sensor is arranged at one end of the elastic member 14 to detect the pressure applied by the elastic member 14 to the water sweeping roller brush 13; for example, the pressure sensor can be arranged between the water sweeping roller brush 13 and the elastic member 14, or the pressure sensor can be arranged between the bracket body 11 and the elastic member 14 bracket.

[0036] The movable arm 3 is connected to the support body 11 and is used to drive the support body 11 to move so as to bring the cleaning roller brush 12 and the water sweeping roller brush 13 into contact with the photovoltaic panel. The movable arm 3 is rotatably mounted on a mobile carrier having an operating platform. For example, the mobile carrier can be a flatbed truck.

[0037] When the photovoltaic panel needs to be cleaned, the cleaning vehicle 100 can be parked next to the photovoltaic panel through the moving function of the mobile carrier, and then the position and angle of the bracket body 11 can be adjusted by using the movable arm 3, and the cleaning roller brush 12 can be stopped on the photovoltaic panel, and the water sweeping roller brush 13 can be stopped on the photovoltaic panel. By monitoring the pressure value detected by the pressure sensor, the angle of the bracket body 11 is adjusted to be appropriate, and then the cleaning liquid (for example, the cleaning liquid can be water, or a mixed liquid containing detergent, specifically, the detergent can be a cationic surfactant, an anionic surfactant, an amphoteric surfactant or a non-ionic surfactant) is sprayed toward the photovoltaic panel to drive the bracket body 11 to move and clean the photovoltaic panel.

[0038] Among them, the method for adjusting the angle of the bracket body 11 to be appropriate is as follows: when the pressure value detected by the pressure sensor is monitored to be greater than the preset value, the water sweeping roller brush 13 can be lifted by rotating the bracket body 11; when the pressure value detected by the pressure sensor is monitored to be less than the preset value, the water sweeping roller brush 13 can be pressed down by rotating the bracket body 11.

[0039] When cleaning the photovoltaic panels, the dust on the photovoltaic panels can be mixed with the cleaning liquid under the action of the cleaning roller brush 12 to form waste liquid. Since the cleaning roller brush 12 and the sweeping roller brush 13 are arranged side by side and stop at the photovoltaic panels, the sweeping roller brush 13 can scrape away the waste liquid, reduce the residual amount of waste liquid on the photovoltaic panels, and improve the cleanliness of the photovoltaic panels.

[0040] By setting a pressure sensor at one end of the elastic member 14, the angle of the bracket body 11 can be adjusted by detecting the pressure value detected by the pressure sensor, so that the water-sweeping roller brush 13 can be reliably attached to the photovoltaic panel, reducing the risk of waste liquid flowing from between the water-sweeping roller brush 13 and the photovoltaic panel to the cleaned area, thereby effectively scraping off the moisture on the photovoltaic panel, improving the cleanliness of the photovoltaic panel, and improving the cleaning effect of the cleaning vehicle 100.

[0041] At the same time, since the cleaning vehicle 100 can adjust the angle of the bracket body 11 by detecting the pressure value detected by the pressure sensor, thereby avoiding excessive pressure exerted by the water sweeping roller brush 13 on the photovoltaic panel, this can effectively reduce the risk of damage to the photovoltaic panel due to excessive pressure exerted by the water sweeping roller brush 13 on the photovoltaic panel, effectively ensure the safety of the photovoltaic panel, and improve the reliability of the cleaning vehicle 100.

[0042] For example, refer to Figure 2 and Figure 3 There can be two elastic members 14, and the two elastic members 14 are arranged at intervals along the axial direction of the water sweeping roller brush 13. The number of pressure sensors is the same as the number of elastic members 14 and corresponds one to one. In this way, the angle of the bracket body 11 can be adjusted on the axis of the water sweeping roller brush 13 by monitoring the pressure values detected by the two pressure sensors, thereby reducing the risk of the water sweeping roller brush 13 applying too much force to the photovoltaic panel at one axial end, and reducing the risk of the water sweeping roller brush 13 applying too little force to the photovoltaic panel at one axial end, so that the pressure applied by the water sweeping roller brush 13 to the photovoltaic panel is uniform and appropriate, effectively ensuring the safety of the photovoltaic panel and improving the reliability of the cleaning vehicle 100.

[0043] For example, refer to Figure 2 and Figure 3 The cleaning vehicle 100 may further include a camera assembly 4, which is disposed on the bracket body 11 and is disposed close to the water sweeping roller brush 13. Specifically, the camera assembly 4 may be disposed on the side of the water sweeping roller brush 13 away from the cleaning roller brush 12. The camera assembly 4 is used to photograph the photovoltaic panel to identify whether a hot spot fault or a crack fault has initially occurred on the photovoltaic panel. In this way, the camera assembly 4 can be used to reliably identify whether a hot spot fault or a crack fault has initially occurred on the photovoltaic panel, thereby improving the accuracy of fault identification of the cleaning vehicle 100.

[0044] According to the cleaning vehicle 100 of the present invention, an elastic member 14 is provided to apply pressure to the water sweeping roller brush 13 so that the water sweeping roller brush 13 is pressed against the photovoltaic panel, and a pressure sensor is provided at one end of the elastic member 14. By detecting the pressure value detected by the pressure sensor, the angle of the bracket body 11 can be adjusted so that the water sweeping roller brush 13 can be reliably attached to the photovoltaic panel, effectively scraping off the moisture on the photovoltaic panel, and improving the cleanliness of the photovoltaic panel. At the same time, the risk of damage to the photovoltaic panel due to excessive pressure applied by the water sweeping roller brush 13 on the photovoltaic panel can be effectively reduced, thereby effectively ensuring the safety of the photovoltaic panel and improving the reliability of the cleaning vehicle 100.

[0045] Reference Figure 2 and Figure 3 According to some embodiments of the present invention, the cleaning vehicle 100 further includes a distance measuring assembly 5 , which is disposed on the support body 11 and located on the side of the cleaning roller brush 12 away from the water sweeping roller brush 13 . The distance measuring assembly 5 is used to detect the distance between the support body 11 and the photovoltaic panel. Because the distance between the rotation center of the cleaning roller brush 12 and the support body 11 is fixed, the distance between the support body 11 and the photovoltaic panel and the distance between the rotation center of the cleaning roller brush 12 and the photovoltaic panel can be monitored using the distance measuring assembly 5 .

[0046] When the distance between the rotation center of the cleaning roller brush 12 and the photovoltaic panel is too large, the movable arm 3 drives the bracket body 11 to move toward the photovoltaic panel to adjust the distance between the rotation center of the cleaning roller brush 12 and the photovoltaic panel to be appropriate. When the distance between the rotation center of the cleaning roller brush 12 and the photovoltaic panel is too small, the movable arm 3 drives the bracket body 11 to be lifted to adjust the distance between the rotation center of the cleaning roller brush 12 and the photovoltaic panel to be appropriate, thereby effectively reducing the risk of the cleaning roller brush 12 damaging the photovoltaic panel, so that the cleaning roller brush 12 can reliably clean the dust on the photovoltaic panel.

[0047] Reference Figure 2 and Figure 3 According to some embodiments of the present invention, the distance measuring assembly 5 includes a plurality of distance measuring sensors 51, which are arranged at intervals along the axial direction of the cleaning roller brush 12. For example, the distance measuring sensors 51 may be ultrasonic sensors, laser sensors, infrared sensors, microwave sensors, or optical distance sensors. For example, there may be two, three, four, or more distance measuring sensors 51.

[0048] In this way, by monitoring the distance between the bracket body 11 and the photovoltaic panel detected by multiple distance measuring sensors 51, that is, monitoring the inclination angle of the cleaning roller brush 12 relative to the photovoltaic panel, the angle of the bracket body 11 can be adjusted on the axis of the cleaning roller brush 12, thereby reducing the risk of the cleaning roller brush 12 being too close to the photovoltaic panel at one axial end and thus damaging the photovoltaic panel, and reducing the risk of the cleaning roller brush 12 being too close to the photovoltaic panel at one axial end and thus being unable to effectively clean the photovoltaic panel, so that the distance between the rotation center of the cleaning roller brush 12 and the photovoltaic panel is maintained at an appropriate distance, effectively ensuring the safety of the photovoltaic panel, so that the cleaning roller brush 12 can reliably clean the photovoltaic panel, and thus improving the reliability of the cleaning vehicle 100.

[0049] Prioritize, refer to Figure 2 and Figure 3 There are two ranging sensors 51, and the two ranging sensors 51 are arranged at both ends of the bracket body 11 in the axial direction of the cleaning roller brush 12. In this way, the inclination angle of the cleaning roller brush 12 relative to the photovoltaic panel can be monitored, and at the same time, the number of ranging sensors 51 is set smaller, thereby reducing the production cost of the cleaning vehicle 100.

[0050] Reference Figure 2 and Figure 3According to some embodiments of the present invention, the water sweeping roller brush 13 includes a water sweeping shaft and a flexible member 131, the water sweeping shaft is connected to the bracket body 11, and the flexible member 131 is sleeved on the circumferential outer side of the water sweeping shaft. For example, the flexible member 131 can be a sponge member, the flexible member 131 can also be a rubber member, or the flexible member 131 can also be a silicone member. When the elastic member 14 presses the flexible member 131 against the photovoltaic panel, the flexible member 131 can be deformed, increasing the contact area between the flexible member 131 and the photovoltaic panel, so that the flexible member 131 and the photovoltaic panel fit reliably, thereby effectively reducing the risk of waste liquid flowing from between the water sweeping roller brush 13 and the photovoltaic panel to the cleaned area, effectively scraping off the moisture on the photovoltaic panel, improving the cleanliness of the photovoltaic panel, and improving the cleaning effect of the cleaning vehicle 100.

[0051] Reference Figures 1-4 According to some embodiments of the present invention, the cleaning mechanism 1 further includes a water sweeping drive member, which is connected to one end of the water sweeping shaft in the axial direction, and the water sweeping drive member is used to drive the water sweeping shaft to rotate. For example, the water sweeping drive member can drive a motor, the water sweeping drive member can also rotate a cylinder, or the water sweeping drive member can rotate a hydraulic cylinder. By driving the water sweeping shaft to rotate through the water sweeping drive member, the flexible member 131 can perform a secondary cleaning of the photovoltaic panel, further improving the cleaning effect of the cleaning mechanism 1.

[0052] Reference Figure 2 and Figure 3 According to some optional embodiments of the present invention, the cleaning vehicle 100 further includes: a spray assembly 6, the spray assembly 6 being disposed on the support body 11 and configured to spray cleaning liquid toward the side of the cleaning roller brush 12 away from the sweeping roller brush 13. For example, the spray assembly may include a liquid storage tank, a plurality of nozzles 62, and a liquid infusion pipeline. The liquid storage tank is disposed on the mobile vehicle and has a receiving chamber for storing cleaning liquid. The plurality of nozzles 62 are disposed on the support body 11 and are spaced apart along the axial direction of the cleaning roller brush 12. The liquid infusion pipeline is disposed on the movable arm 3, the liquid outlet of the liquid infusion pipeline being connected to the nozzle 62, and the liquid inlet of the liquid infusion pipeline being disposed in the receiving chamber.

[0053] By setting up the spray component 6, the cleaning liquid can be sprayed more accurately near the cleaning roller brush 12, so that the cleaning roller brush 12 can use the cleaning liquid sprayed by the spray component 6 to clean the photovoltaic panel in time, reducing the amount of cleaning liquid lost due to not contacting the cleaning roller brush 12, making full use of the cleaning liquid sprayed by the spray component 6, reducing the use of cleaning liquid, and reducing cleaning costs.

[0054] Reference Figure 2-Figure 4In some optional embodiments of the present invention, the cleaning mechanism 1 further includes a first cleaning drive member 121 having output shafts at both ends of the cleaning roller brush 12 in the axial direction. The cleaning roller brush 12 includes a first sub-roller brush 122 and a second sub-roller brush 123, which are respectively connected to the two output shafts of the first cleaning drive member 121. This ensures that the force on the first cleaning drive member 121 is balanced and the axial lengths of the first sub-roller brush 122 and the second sub-roller brush 123 are both shorter, effectively reducing the vibration amplitude of the end of the first sub-roller brush 122 away from the first cleaning drive member 121 and the vibration amplitude of the end of the second sub-roller brush 123 away from the first cleaning drive member 121. This effectively reduces the risk of the first sub-roller brush 122 and the second sub-roller brush 123 damaging the photovoltaic panel, thereby improving the reliability of the cleaning mechanism 1.

[0055] According to other optional embodiments of the present invention, the cleaning roller brush 12 includes a third sub-roller brush and a fourth sub-roller brush, and the third sub-roller brush and the fourth sub-roller brush are arranged along the axial direction of the cleaning roller brush 12. The cleaning mechanism 1 also includes a second cleaning drive and a third cleaning drive, the second cleaning drive is connected to the end of the third sub-roller brush away from the fourth sub-roller brush, and the third cleaning drive is connected to the end of the fourth sub-roller brush away from the third sub-roller brush. In this way, the axial spacing between the third sub-roller brush and the fourth sub-roller brush can be set to be smaller, so that the third sub-roller brush and the fourth sub-roller brush can fully clean the area swept by the cleaning mechanism 1, thereby improving the cleaning effect of the photovoltaic panel.

[0056] Reference Figure 1 According to some other optional embodiments of the present invention, the movable arm 3 includes a turntable 31, a first arm 32, a second arm 33, and a third arm 34. The turntable 31 is rotatably mounted on a mobile carrier. The first arm 32 is connected to the turntable 31 and extends in the vertical direction. The second arm 33 is vertically swingably connected to an end of the first arm 32 away from the turntable 31. The third arm 34 is vertically swingably connected to an end of the second arm 33 away from the turntable 31. The bracket body 11 is connected to an end of the third arm 34 away from the second arm 33. In this way, the distance between the bracket body 11 and the photovoltaic panel can be adjusted by swinging the second arm 33 and the third arm 34, and the angle between the cleaning roller brush 12 and the photovoltaic panel, as well as the angle between the water sweeping roller brush 13 and the photovoltaic panel, can be adjusted by rotating the turntable 31.

[0057] Reference Figure 1In other optional embodiments of the present invention, the third arm 34 includes a rotary drive member, the output shaft of which is connected to the support body 11 and is used to drive the support body 11 to rotate along the rotation axis of the third arm 34. For example, the rotary drive member may be a drive motor, a rotary cylinder, or a rotary hydraulic cylinder. In this way, the rotary drive member can be used to drive the support body 11 to rotate along the rotation axis of the third arm 34, eliminating the need to drive the turntable 31 to rotate the first arm 32, the second arm 33, and the third arm 34, which then drives the support body 11 to rotate. This reduces the number of components involved in adjusting the angle between the cleaning roller brush 12 and the photovoltaic panel, making the adjustment easier. Furthermore, it reduces the number of components involved in adjusting the angle between the cleaning roller brush 12 and the photovoltaic panel, making the adjustment easier.
