A lifting assembly is installed in each of the two transmission cavities. The two ends of the two cleaning shafts 10 pass through the four sliding holes and are connected to the lifting assembly. The two cleaning roller brushes 5 are fixedly sleeved on the two cleaning shafts 10 respectively.

[0029] The self-cleaning mechanism includes a fixed scraper 12, the two ends of which are fixedly connected to the opposite sides of the two side plates 4, the fixed scraper 12 is adapted to the two cleaning roller brushes 5, and the top of the fixed scraper 12 is slidably installed with two rectangular plates 15 through two reciprocating components. Two cleaning scrapers 17 are provided at the bottom of the two rectangular plates 15, an air hole is opened at the bottom of the mounting plate 3, an exhaust pipe 18 is provided at the top of the mounting plate 3, an air pump 19 is provided on the exhaust pipe 18, and a driving component adapted to the reciprocating component is provided in the air hole.

[0030] The robot in the present invention is provided with a controller, a power supply, an identification sensor, an operation panel and a signal transceiver, and can be remotely controlled through a mobile phone control terminal or a computer control terminal; the operating data should be able to be saved in the cloud, and at the same time, the parameters should be able to be set and adjusted on-site through the operation panel, for example, the operating time, number of operations, upper limit current, and potential difference value can be set remotely or at the machine, and the human-machine interface is convenient to operate, responds promptly, and displays correctly. It is a prior art and will not be described in detail.

[0031] During cleaning, a single robot has a cleaning efficiency of 60 square meters per hour. For a cluster of 28 panels, the largest on-site single panel is 3.1 square meters, and a single robot takes 2.5 hours to clean a cluster.

[0034] The robot's cleaning rate for photovoltaic strings is 99.5%, and no blind spots are left.

[0035] The robot has a net weight of 6.5kg, a length of 1150mm, and a width and thickness of 180mm. It can be operated by one person and will not cause damage to the photovoltaic panels due to the weight of the robot when placed on them.

[0036] The robot requires a dedicated carrying case for storage and transportation. The case provides cushioning and protection for the robot. The total weight of the case, the robot, and its accessories is 8.2 kg, making it easy for one person to carry.

[0037] At the same time, the robot can pass through the joints between photovoltaic panels (2±0.5cm) without obstacles. The robot can effectively identify the edge of the string through sensors and has the logic function to prevent edge falling.

[0038] With the above structure, when in use, the robot is first placed on the top of the photovoltaic panel, and the position of the cleaning roller brush 5 is adjusted by the walking mechanism 1 and the telescopic mechanism 2, so that one of the cleaning roller brushes 5 contacts the top of the photovoltaic panel, and the surface of the photovoltaic panel is cleaned by the movement of the robot and the rotation of the cleaning roller brush 5. After cleaning for a long time, a large amount of dust and foreign matter adheres to the surface of the cleaning roller brush 5, and the cleaning effect is reduced. At this time, the two cleaning roller brushes 5 are driven by the lifting component to move in the opposite direction, so that the other cleaning roller brush 5 is cleaned, thereby improving the cleaning effect. At the same time, the driving component and the air pump 19 work, and under the cooperation of the driving component and the reciprocating component, the cleaning roller brush 5 located above is self-cleaned, thereby improving the subsequent cleaning effect.

[0039] like Figure 2 As shown, the lifting assembly includes a rotating shaft 7, and a rotating hole is opened on the inner wall of the two transmission chambers that are close to each other. The rotating shaft 7 is rotatably installed in the two rotating holes. The two ends of the rotating shaft 7 are respectively rotatably installed on the inner walls of the two transmission chambers that are away from each other. Two gears 8 are fixedly sleeved on the rotating shaft 7, and two lifting racks 6 are slidably installed in the two transmission chambers through the limit units. In this arrangement, through the meshing action of the two gears 8 and the four lifting racks 6, the rotating shaft 7 drives the four lifting racks 6 to move synchronously when it rotates.

[0040] Specifically, when the two cleaning roller brushes 5 need to be switched, the rotating shaft 7 is rotated to drive the two gears 8 to engage with the four lifting racks 6, so that the four lifting racks 6 drive the two cleaning shafts 10 to move in the opposite direction, thereby realizing the switching function of the two cleaning roller brushes 5.

[0041] like Figure 2 、 Figure 3As shown, a conversion motor 9 is fixedly installed on the side of one of the side panels 4, and the output shaft of the conversion motor 9 is connected to the end of the rotating shaft 7. The sides of the two lifting racks 6 are provided with equipment slots, and the two equipment slots are provided with first cleaning motors 11. The output shafts of the two first cleaning motors 11 are respectively connected to the ends of the two cleaning shafts 10. In this way, the conversion motor 9 and the first cleaning motor 11 can be used to drive the conversion shaft 7 and the cleaning shaft 10 to realize the rotation function.

[0042] Specifically, the conversion motor 9 and the first cleaning motor 11 respectively drive the rotating shaft 7 and the cleaning shaft 10 to rotate, which can facilitate the operation of the staff.

[0043] like Figure 2 As shown, the limiting unit includes two limiting slides 26, and the relative inner walls of the transmission cavity are provided with lifting grooves. The two limiting slides 26 are respectively slidably installed in the two lifting grooves, and the sides of the two lifting racks 6 are respectively fixedly connected to the sides of the two limiting slides 26. The two lifting racks 6 are both engaged with the gear 8. The heights of the two lifting racks 6 located in the same transmission cavity are different. The two ends of the two cleaning shafts 10 are respectively rotatably installed on the sides of the four lifting racks 6. This arrangement can limit the sliding direction of the lifting rack 6 to prevent tilting.

[0044] Specifically, the two limiting slide bars 26 slide in the lifting groove to limit the sliding direction of the lifting rack 6 to prevent the lifting rack 6 from tilting.

[0045] like Figure 4 As shown, the reciprocating assembly includes a reciprocating screw 14, a square plate 13 is provided on the top of the fixed scraper 12, the two ends of the reciprocating screw 14 are rotatably mounted on the opposite sides of the square plate 13 and the side plate 4, and the rectangular plate 15 is threadedly mounted on the reciprocating screw 14. A limiting unit is provided on the side of the rectangular plate 15. With this arrangement, the reciprocating screw 14 can be rotated, thereby driving the rectangular plate 15 under the action of the thread to realize the reciprocating horizontal motion function.

[0046] Specifically, when the cleaning roller brush 5 needs to be cleaned, by rotating the reciprocating screw 14, the rectangular plate 15 can be driven to move back and forth horizontally under the action of the thread, thereby driving the cleaning scraper 17 to move horizontally synchronously, and cooperating with the fixed scraper 12 to clean the surface of the cleaning roller brush 5.

[0047] like Figure 4 As shown, the limiting unit includes a limiting shaft 16, a limiting hole is opened on the side of the rectangular plate 15, the limiting shaft 16 is slidably installed in the limiting hole, and the two ends of the limiting shaft 16 are respectively fixedly installed on the opposite sides of the square plate 13 and the side plate 4. Through the setting of the limiting shaft 16, the limiting function of the rectangular plate 15 can be realized.

[0048] Specifically, when the reciprocating screw 14 rotates, the limiting shaft 16 limits the rectangular plate 15, which can effectively prevent it from rotating synchronously with the rotation of the reciprocating screw 14, thereby improving the stability of the rectangular plate 15 during movement.

[0049] like Figure 2 、 Figure 4 As shown, the driving assembly includes an arc-shaped plate 20, which is fixedly mounted on the inner wall of the circumference of the air hole. A rotating hole is opened at the bottom of the arc-shaped plate 20, and a rotating rod 21 is rotatably mounted in the rotating hole. A second cleaning motor 22 is fixedly arranged on the top of the rotating rod 21, and the output shaft of the second cleaning motor 22 is fixedly connected to the top of the rotating rod 21. The bottom end of the rotating rod 21 is fixedly sleeved with a driving bevel gear 23, and the reciprocating screw 14 is fixedly sleeved with a driven bevel gear 24. A collecting box 25 is provided on the top of the mounting plate 3. In this arrangement, the second cleaning motor 22 can drive the driving bevel gear 23 to engage with the driven bevel gear 24, thereby driving the reciprocating screw 14 to realize the rotation function.

[0050] Specifically, when the second cleaning motor 22 is working, it drives the rotating rod 21 and the active bevel gear 23 to rotate synchronously, and through the meshing action with the driven bevel gear 24, it drives the reciprocating screw 14 to realize the rotation function, and through the air pump 19 to suck air, the dust and foreign matter cleaned can be collected into the collection box 25 to prevent them from escaping and falling onto the surface of the photovoltaic panel.

[0051] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
