Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic product cleaning, in particular to a cleaning device for a photovoltaic power generation panel. Background Art

[0002] Since the photovoltaic power generation panel is installed outdoors, during long-term use, the photovoltaic power generation panel is easily affected by external pollutants such as dust, resulting in a decrease in the light transmittance and photoelectric conversion efficiency of the photovoltaic power generation panel. Therefore, it is necessary to clean the pollutants on the surface of the photovoltaic power generation panel.

[0003] Based on this, in the prior art, as shown in the publication number CN220067363U, a cleaning device for a photovoltaic power generation panel is disclosed, which includes a mobile cart, a driving arm and a water supply mechanism arranged on the mobile cart, and a cleaning mechanism arranged at the output end of the driving arm, and also includes a pre-cleaning unit; by arranging a pre-cleaning unit in front of the cleaning brush roller of the cleaning device to absorb the grit on the photovoltaic panel, it is avoided that the cleaning brush roller squeezes the grit and slides on the photovoltaic panel when cleaning the panel, and the phenomenon that the grit causes scratches on the surface of the photovoltaic panel can be prevented. However, after cleaning the photovoltaic power generation panel, this kind of cleaning device cannot timely air-dry the surface of the photovoltaic power generation panel, so that a large amount of water droplets are likely to remain on the surface of the photovoltaic power generation panel to form water stains, thereby reducing the cleaning effect of the photovoltaic power generation panel.

[0004] In addition, the publication number CN218023583U also discloses a cleaning and conveying device for a solar panel, and this cleaning and conveying device can perform an air-drying operation on the cleaned solar panel. However, the corners of the solar panel are more likely to accumulate pollutants such as dust compared to other local areas. And this cleaning and conveying device cleans the solar panel by conveying the solar panel to the lower part of a cleaning component such as a hair roller through a conveyor belt; therefore, this cleaning and conveying device cannot adjust the angle of the cleaning component such as a hair roller, nor can it move the entire cleaning and conveying device arbitrarily, and the cleaning operation is not flexible, making it difficult to achieve thorough cleaning of the corners of the solar panel, resulting in a poor cleaning effect.

[0032] Among them, the supporting mechanism 2 includes a robotic arm 21 and a supporting assembly 22. One end of the robotic arm 21 is rotatably installed on the moving vehicle 1, and the supporting assembly 22 is rotatably connected to the other end of the robotic arm 21, so that the robotic arm 21 can drive the supporting assembly 22 to rotate and adjust the angle, and further, through the rotation and angle adjustment of the supporting assembly 22, the cleaning mechanism 3 and the air drying mechanism 4 can respectively perform thorough cleaning and air drying on the corners of the photovoltaic power generation panel (dust and other pollutants are more likely to accumulate at the corners), so as to improve the cleaning effect.

[0033] Moreover, by pushing the moving vehicle 1, the entire cleaning device can be moved arbitrarily, making the use of the cleaning device more convenient.

[0034] In practice, the robotic arm 21 is preferably a six-axis robotic arm to make the cleaning and air drying operations more flexible and fast.

[0035] Specifically, the supporting assembly 22 includes a bracket 221, a first support plate 222 and a second support plate 223. The number of the first support plates 222 is preferably two, and the two first support plates 222 are respectively fixedly connected to the left and right sides at the rear of the bracket 221 (as Figure 1 shown). The number of the second support plates 223 is preferably two, and the two second support plates 223 are respectively fixedly connected to the left and right sides at the front of the bracket 221 (as Figure 1As shown in the figure, the top of the bracket 221 is connected to the robotic arm 21.

[0036] Refer to Figures 1-3 , the air-drying mechanism 4 includes a fan 401 (such as a blower 401) and an air supply assembly connecting to the fan 401. The fan 401 is installed on the top of the mobile vehicle 1. The air supply assembly includes a delivery pipe 404, an air supply pipe 402, and a first nozzle 403. The inlet of the delivery pipe 404 is connected to the fan 401, and the outlet of the delivery pipe 404 is connected to the air supply pipe 402. The outlet of the air supply pipe 402 is connected to the first nozzle 403 (as Figure 3 shown in the figure), and the first nozzle 403 is installed at the bottom of the air supply pipe 402; both ends of the air supply pipe 402 are fixedly connected to two first support plates 222 respectively.

[0037] In this way, through the cooperation of the above-mentioned fan 401, delivery pipe 404, air supply pipe 402, and first nozzle 403, the airflow generated by the fan 401 is transported to the air supply pipe 402 through the delivery pipe 404, and then quickly reaches the first nozzle 403, so that the first nozzle 403 can blow away the sand and gravel on the surface of the photovoltaic power generation panel to prevent the sand and gravel from scratching the surface of the photovoltaic panel, can also blow away the dirt on the cleaning mechanism 3, and can also blow away the water droplets on the surface of the photovoltaic power generation panel in time to dry it quickly, preventing water stains from remaining on the surface of the photovoltaic power generation panel. Therefore, the cleaning effect of the photovoltaic power generation panel is effectively improved.

[0038] Refer to Figures 1-3 , the cleaning mechanism 3 includes a cleaning member 307, a water supply assembly installed on the mobile vehicle 1, and a water delivery assembly connecting to the water supply assembly. The water supply assembly includes a water tank 301, a diversion pipe 305, and a water pump 302 installed on the top of the mobile vehicle 1; the inlet of the diversion pipe 305 is connected to the water tank 301, and the outlet of the diversion pipe 305 is connected to the water pump 302. The water delivery assembly includes a connecting pipe 306, a shunt pipe 303, and a second nozzle 304 for rinsing the photovoltaic power generation panel. The inlet of the connecting pipe 306 is connected to the water pump 302, the outlet of the connecting pipe 306 is connected to the shunt pipe 303, the outlet of the shunt pipe 303 is connected to the second nozzle 304, and the second nozzle 304 is installed at the bottom of the shunt pipe 303; both ends of the shunt pipe 303 are fixedly connected to two second support plates 223 respectively. The cleaning member 307 is installed at the bottom of the bracket 221, and the cleaning member 307 is preferably a cleaning roller.

[0039] In this way, through the cooperation of the above-mentioned water tank 301, diversion pipe 305, water pump 302, connecting pipe 306, shunt pipe 303 and second nozzle 304, the water tank 301, diversion pipe 305 and water pump 302 are used to provide flushing water, and then the flushing water quickly reaches the second nozzle 304 through the connecting pipe 306, shunt pipe 303 and second nozzle 304 in sequence. Therefore, the second nozzle 304 can timely shower the surface of the photovoltaic power generation panel; combined with the rotation of the cleaning roller, the cleaning roller can clean the dirt on the surface of the photovoltaic power generation panel, and thus the photovoltaic power generation panel can be cleaned in real time.

[0040] Moreover, since the top and bottom of the bracket 221 are respectively connected to the robotic arm 21 and the cleaning roller, the air supply pipe 402 (with the first nozzle 403 installed at its bottom) is fixedly connected to the first support plate 222 fixedly connected to the rear side of the bracket 221, and the shunt pipe 303 (with the second nozzle 304 installed at its bottom) is fixedly connected to the second support plate 223 fixedly connected to the front side of the bracket 221; thus, the first nozzle 403 is located at the rear side of the cleaning member 307 (such as the cleaning roller), and the second nozzle 304 is located at the front side of the cleaning member 307. Therefore, the cleaning device of this embodiment also has the following advantages: the structure of the cleaning device is reasonably designed, with good structural stability, and can quickly realize the showering, cleaning and drying of the surface of the photovoltaic power generation panel in sequence, which helps to improve the cleaning efficiency; and only the robotic arm 21 needs to drive the bracket 221 to rotate (or adjust the working angle), then the first nozzle 403, the cleaning roller and the second nozzle 304 can synchronously rotate (or adjust the working angle) with the bracket 221, and the operation is more flexible and convenient.

[0041] See Figure 1 , 4 , in order to provide driving force for the cleaning roller, a driving mechanism 5 is also installed on the bracket 221, and the driving mechanism 5 is connected to the cleaning roller to drive the cleaning roller to automatically perform the cleaning work.

[0042] Specifically, installation grooves 224 are formed on both the left and right sides of the bottom of the bracket 221, a moving wheel 225 is installed in the inner cavity of the installation groove 224, and the moving wheel 225 is movably connected to the inner wall of the installation groove 224 through a connecting member such as a bearing; one end of the cleaning roller is rotatably connected to the moving wheel 225 in the bracket 221 through a connecting member such as a bearing.

[0043] Moreover, the driving mechanism 5 includes a driving member 501 (such as a servo motor), a driving wheel 502, a driven wheel 503, a transmission rod 504 and a support rod 505. The driving member 501 is fixed to the outer surface of the bracket 221, and the driving wheel 502, the driven wheel 503 and the support rod 505 are all installed in the inner cavity of the bracket 221. The driving wheel 502 and the driven wheel 503 are drivingly connected by a belt 506. One end of the transmission rod 504 is fixedly connected to the cleaning roller, and the other end of the transmission rod 504 penetrates into the inner cavity of the bracket 221 and is fixedly connected to the driven wheel 503. The output shaft of the driving member 501 penetrates into the inner cavity of the bracket 221 and is drivingly connected to the driving wheel 502. One end of the support rod 505 is fixedly connected to the driven wheel 503, and the other end of the support rod 505 is rotatably connected to the inner wall of the bracket 221 through a connecting member such as a bearing.

[0044] During operation, the driving member 501 drives the driving wheel 502 to rotate, and the driving wheel 502 then drives the driven wheel 503 to rotate through the belt 506, so that the driven wheel 503 drives the cleaning roller to rotate through the support rod 505 and the transmission rod 504, enabling the cleaning roller to automatically perform the cleaning work.
