Description

Technical Field

[0001] The invention relates to the technical field of robots, and in particular to a photovoltaic panel cleaning robot capable of collecting dust. Background Art

[0002] Photovoltaic power generation is a renewable energy source and has developed rapidly in my country in recent years. The cleanliness of the surface of photovoltaic panels directly affects the power generation efficiency. The surface of photovoltaic panels is exposed to the air and it is easy for dust and bird droppings to accumulate. Timely cleaning of these pollutants to ensure efficient power generation of photovoltaic panels has become one of the important tasks in the operation and maintenance of photovoltaic power stations.

[0003] Existing photovoltaic panel cleaning machines have the following defects during the cleaning process: 1. Dust is directly swept into the air by the rolling brush, and most of the raised dust falls on the surface of the photovoltaic panel to form secondary pollution; 2.

The cleaning machine body (4) is a rectangular structure and is mounted on the upper surface of the photovoltaic panel (1). The cleaning machine body (4) can move back and forth in the length direction of the photovoltaic panel (1) through the driving of the walking wheels (10).

[0018] 2. A solar cell (2) is installed on the uppermost surface of the cleaning machine body (4) to provide power for the operation of the machine, and a semicircular sealing groove (20), a right sealing roller (7), a rolling brush (9), and a left sealing roller (8) are installed below the cleaning machine body in sequence; the right sealing roller (7) and the left sealing roller (8) are made of a sponge material and have good deformation and resilience, and are closely attached to the surface of the photovoltaic panel (1) of the semicircular sealing groove (20) to form a closed-loop sealed cavity such as Figure 5 As shown, dust can be effectively prevented from spilling out, and dust can only flow in the length direction of the rolling brush (9).

[0019] 3. A centrifugal fan (6) is installed at the lower end of the cleaning machine body (4) in the longitudinal direction, and the air outlet of the centrifugal fan (6) is communicated with a closed-loop sealing chamber composed of a semicircular sealing groove (20), a right sealing roller (7), a left sealing roller (8), and a photovoltaic panel (1).

[0020] 4. An air filter box (3) is installed at the upper end of the length direction of the cleaning machine body (4). The lower part of the air filter box (3) is provided with an exhaust port (11) and a dust exhaust port (12). A dust removal motor (13) is installed in the upper part of the inner part. The rotating shaft of the dust removal motor (13) is connected to the shaft of the dust removal brush (14). The dust removal brush (14) is inserted into the upper part of the cavity of the cylindrical dust filter (15). The dust filter (15) is communicated with a closed-loop sealed cavity composed of a semicircular sealing groove (20), a right sealing roller (7), a left sealing roller (8) and a photovoltaic panel (1). The dust storage cavity (18) is located directly below the dust filter (15). A dust collection valve (16) is installed at the upper part of the cavity. A dust exhaust valve (19) is installed at the lower part and communicates with the dust exhaust port (12). A wind speed monitor (17) is installed directly above the exhaust port (11) at the bottom of the air filter box (3).

[0021] 5. An image scanning processor (5) is installed on the outer side of the long side of the cleaning machine body (4) close to the starting direction of walking.

[0022] The following is a detailed and complete explanation of the technical solutions and mechanical movements in the embodiments of the present invention in conjunction with the drawings of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Other embodiments obtained by ordinary technicians in this field without making creative improvements all belong to the scope of protection of the present invention. The realization of these functions is explained one by one in conjunction with the above drawings.

[0023] When the cleaning machine body (4) receives a cleaning command, the centrifugal fan (6) starts to supply air, and at the same time, the rolling brush (9), the right sealing roller (7), the left sealing roller (8), and the walking wheel (10) start to rotate to perform the cleaning operation. Their rotational kinetic energy all comes from their respective drive motors. In order to simplify the drawings and save time for the examiner, this drive motor is not drawn on the drawings.

[0024] During the cleaning process, the dust swept by the rolling brush (9) enters the interior of the dust filter (15) under the action of the wind force of the centrifugal fan (6). After the airflow carrying dust reaches the filter, the dust is blocked on the inner surface of the filter. The clean air passes through the filter and is ejected from the exhaust port (11) through the wind speed monitor (17).

[0025] As the cleaning time increases, more and more dust accumulates on the inner surface of the dust filter (15), and the wind speed monitor (17) detects that the airflow passing through the filter decreases accordingly. When the set minimum air volume is reached, the dust removal motor (13) starts, the dust collection valve (16) opens, and the dust removal brush (14) rotates and descends to the dust filter (15) filter. Figure 7As shown, the accumulated dust quickly falls into the dust storage chamber (18). As the dust is removed, the wind speed monitor (17) detects that the airflow is increasing. When the airflow reaches a set value, the dust removal motor (13) stops, the dust collection valve (16) closes, and the dust removal brush (14) returns to its initial position. Figure 6 As shown, when the cleaning work is completed, the dust discharge valve (19) opens to discharge the dust accumulated in the dust storage chamber (18) from the dust discharge port (12). Figure 8 As shown, after the dust is discharged, the dust discharge valve (19) is closed. The above process ensures that the dust swept out can be collected and processed in time, and avoids the dust being raised in the air to cause secondary pollution to the surface of the photovoltaic panel.

[0026] During the cleaning process: while the cleaning machine body (4) moves forward, the image scanning processor (5) analyzes the image of the cleaned surface. When it is found that there is bird droppings or debris that has not been cleaned up, a return command is issued to the walking wheel (10) to clean it again. If it still cannot be cleaned up after cleaning back and forth three times, this point will not be cleaned anymore and subsequent cleaning tasks will be carried out. The image scanning processor (5) sends the coordinates and pictures of the contaminated point to the staff's mobile phone app for manual processing, thereby ensuring the power generation efficiency of the photovoltaic panel and the safety of the equipment.
