[0025] The technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0026] like Figure 1 and Figure 2 As shown, the embodiment of the present invention proposes a photovoltaic panel cleaning and maintenance device, which is arranged on a support frame 2 and is used to clean a photovoltaic panel body 1, comprising:

[0027] Two mounting plates 3 are arranged on the support frame 2 and located on both sides of the photovoltaic panel body 1;

[0028] A roller brush 9 is disposed between two mounting plates 3, and mounting frames 6 are slidably disposed on both mounting plates 3. The roller brush 9 is rotatably disposed between the two mounting frames 6, and one of the mounting frames 6 is provided with a second motor 901, and the second motor 901 is connected to the roller brush 9; and

[0029] The transmission assembly includes a sliding seat 5 slidably arranged on the mounting plate 3 and connected to the corresponding mounting frame 6, and a transmission member rotatably arranged on the mounting plate 3. The transmission member is connected to the sliding seat 5, so that the sliding seat 5 drives the roller brush 9 to reciprocate along the length direction of the mounting plate 3 to roll and clean the photovoltaic panel body 1.

[0030] In an embodiment of the present invention, before use, two mounting plates 3 are installed on both sides of a support frame 2 for mounting a photovoltaic panel body 1, so that a roller brush 9 installed between the two mounting plates 3 can cover the entire photovoltaic panel body 1. Specifically, when cleaning the photovoltaic panel body 1, a second motor 901 connected to the roller brush 9 is started so that the output shaft of the second motor 901 rotates to automatically drive the roller brush 9, so that the roller brush 9 and the photovoltaic panel body 1 are continuously rubbed, thereby effectively removing dust and impurities attached to the photovoltaic panel body 1.

[0031] At the same time, under the action of the transmission component, the sliding seat 5 can be slidably installed on the mounting plate 3, and the sliding seat 5 is driven to slide back and forth on the mounting plate 3 through the action of the transmission member, so that the sliding seat 5 drives the roller brush 9 to perform reciprocating cleaning motion on the surface of the photovoltaic panel body 1, so that the roller brush 9 can perform a large-scale cleaning on the surface of the photovoltaic panel body 1, and ensure that all areas of the photovoltaic panel surface 1 are evenly cleaned, thereby improving the cleaning quality, and no manual intervention is required throughout the process. The transmission component, the second motor 901 and the roller brush 9 can automatically maintain and clean the photovoltaic panel body 1 on the support frame 2, thereby ensuring the cleanliness of the photovoltaic panel body surface 1, thereby improving the working efficiency of the photovoltaic panel body 1.

[0032] Based on the above scheme, if Figure 2 As shown, the transmission member includes a sprocket 4 rotatably arranged at the end of the mounting plate 3, the two sprockets 4 are connected by a chain 402, the chain 402 is rotatably provided with a driving rod 403, the sliding seat 5 is provided with a driving groove 501 along its height direction, the driving rod 403 is slidably arranged in the driving groove 501, and a first motor 401 is provided on the side of the mounting plate 3, and the first motor 401 is connected to one of the sprockets 4.

[0033] Specifically, when the reciprocating motion of the sliding seat 5 is implemented by the action of the transmission member, when the first motor 401 is started, the output shaft of the first motor 401 drives the connected sprocket 4 to rotate, and under the action of the chain 402, the two sprockets 4 rotate synchronously, which can also be regarded as the chain 402 sliding between the two sprockets 4, and the driving rod 403 is rotated and arranged on one of the segments of the chain 402. When the chain 402 moves, the driving rod 403 makes a circular motion along the trajectory of the movement of the chain 402. Since the driving rod 403 is slidably connected to the driving groove 501, when the driving rod 403 moves, the sliding seat 5 will be affected by the force of the driving rod 403 and follow the movement of the driving rod 403. The entire circular motion of the chain 402 is regarded as an upper segment, a lower segment and two arc segments (i.e., the interval segment where the chain 402 is combined with the sprocket 4). Figure 3For example, when the driving rod 403 is located in the upper section, the driving rod 403 is clamped on the top of the driving groove 501. When the driving rod 403 is located in the arc section, the driving rod 403 gradually moves from the top of the driving groove 501 to the bottom of the driving groove 501 until the driving rod 403 is located in the lower section. The driving rod 403 is at the bottom of the driving groove 501. Repeating the above steps can realize the reciprocating motion of the sliding seat 5 on the mounting plate 3.

[0034] Specifically, Figure 2 As shown, a connecting rod 8 is inserted between the two mounting plates 3, and the two ends of the connecting rod 8 are respectively connected to the corresponding sprockets 4; since the sprockets 4 on the two mounting plates 3 need to move synchronously, in order to reduce the use of equipment, that is, the number of first motors 401, the first motor 401 of one of the mounting plates 3 can be cancelled, and the corresponding two sprockets 4 in the two mounting plates 3 are connected by the connecting rod 8. When the sprocket 4 in one of the mounting plates 3 rotates, the sprocket in the other mounting plate 3 can be driven synchronously to achieve synchronous operation, which also improves the coordination of the reciprocating motion of the roller brush 9.

[0035] Specifically, Figure 5 As shown, the mounting plate 3 is provided with a slide groove 301, and a pulley block 404 is provided on the inner side of the sliding seat 5, and the pulley block 404 rolls in contact with the slide groove 301; the cooperation between the slide groove 301 and the pulley block 404 can provide a better guiding effect, ensuring that the sliding seat 5 moves smoothly along a predetermined trajectory, avoiding the problem of incomplete cleaning due to deviation of the sliding seat 5, and the pulley block 404 allows the sliding seat to move on the mounting plate 3 more smoothly, reduces friction, effectively reduces energy consumption, and increases the service life of the system.

[0036] Based on the above scheme, if Figure 3 As shown, a mounting block 601 is slidably provided in the mounting frame 6, and the roller brush 9 is provided between the two mounting blocks 601. The second motor 901 is connected to one of the mounting blocks 601. The mounting block 601 is rotatably provided with a spring sheet 602, and the other end of the spring sheet 602 is rotatably provided on the inner side of the mounting frame 6. Under the action of the spring sheet 602, a certain buffering effect can be provided for the roller brush 9. When the roller brush 9 encounters foreign matter or surface protrusions, it can not only avoid the roller brush 9 from causing a hard impact on the photovoltaic panel body 1, thereby reducing the potential damage to the photovoltaic panel body 1, but also reduce the rigid contact between the roller brush 9 and the photovoltaic panel body 1. When encountering an uneven surface, the roller brush 9 can float up and down, thereby maintaining good contact with the surface of the photovoltaic panel body 1, which helps to extend the service life of the roller brush 9. In addition, the spring sheet 602 enables the roller brush 9 to automatically adjust the applied pressure according to the specific conditions of the surface of the photovoltaic panel body 1, ensuring that the roller brush 9 always abuts against the surface of the photovoltaic panel body 1, ensuring the quality of cleaning and maintenance.

[0037] Based on the above scheme, if Figure 2 and Figure 4 As shown, the roller brush 9 is provided with a plurality of water outlet holes 902, another mounting block 601 is provided with a rotary joint 7, the end of the rotary joint 7 is provided with a delivery pipe 701, and the other end of the rotary joint 7 is connected to the roller brush 9; the delivery pipe 701 is connected to an external water source, and the cleaning water or cleaning liquid wets the roller brush 9 through the plurality of water outlet holes 902 of the roller brush 9, which can not only reduce the friction damage of dust particles to the surface of the photovoltaic panel, but also help soften stubborn stains, more effectively remove dust and other pollutants on the surface of the photovoltaic panel body 1, thereby improving the cleaning quality and ensuring the power generation efficiency of the photovoltaic panel body 1. The use of the rotary joint 7 allows the roller brush 9 to continue to supply water while rotating, ensuring the continuity of the cleaning process, and the water supply will not be interrupted due to the rotation of the roller brush 9.

[0038] Specifically, Figure 1 As shown, the support frame 2 is provided with a water tank 201, and the delivery pipe 701 runs through the inside of the water tank 201; the water tank 201 with a top opening is installed on the side of the support frame 2, and the water tank 201 is provided with a water pump for delivering water. The water tank 201 can be used to collect rainwater from the outside and be used as a source of clean water, which effectively saves resources. Especially in areas where water supply is difficult, the water tank 201 can be used to store water for easy cleaning.

[0039] Secondly, the water tank 201 is provided with a filter 202; the filter 202 can intercept impurities in the water, such as sand, fiber, leaves, etc., to ensure that the water entering the water tank 201 is clean, and can prevent these impurities from clogging the delivery pipe 701 or damaging the cleaning parts such as the roller brush 9, thereby extending the service life of the equipment.

[0040] Specifically, Figure 1 As shown, a shielding plate 603 is provided between the two mounting frames 6; in an outdoor environment, the roller brush 9 is shielded by the shielding plate 603 so that the roller brush 9 is located between the photovoltaic panel body 1 and the shielding plate 603, effectively preventing the photovoltaic panel body 1 from being exposed to direct sunlight, thereby ensuring the long-term service life of the roller brush 9.

[0041] In summary, according to the combined length of the photovoltaic panel body 1, mounting plates 3 and chains 402 of different lengths can also be customized to maintain and clean photovoltaic panel bodies 1 of different combined areas, and each group of photovoltaic panel bodies 1 corresponds to a cleaning and maintenance device, which can release manpower to a great extent and ensure the normal working efficiency of the photovoltaic panel body 1.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
