[0061] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0063] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0064] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0065] Photovoltaic plants usually have multiple photovoltaic arrays, each of which is composed of multiple photovoltaic panels. Dust on the photovoltaic panels will not only affect the power generation efficiency of the photovoltaic panels, but also affect the service life of the photovoltaic panels over time. When using photovoltaic cleaning robots to clean photovoltaic panels, the cleaning effect of photovoltaic panels is poor.

[0066] like Figure 2 , Figure 3 , Figure 4 , Fig.10 As shown, a specific implementation of the cleaning component provided in this embodiment includes: a shell 1, a first roller brush 6, and a second roller brush 8. The shell 1 has an air duct 2 at the bottom, and the air duct 2 includes a first groove 3 and at least one channel 4. The channel 4 is located above the first groove 3 and is connected to the first groove 3. The channel 4 is configured to connect the first groove 3 with the fan 5. The first roller brush 6 is rotatably arranged in the first groove 3. The first roller brush 6 has at least one group of first bristles 7 in the circumferential direction. The second bristles 9 are rotatably arranged in the first groove 3. The second roller brush 8 is located behind the first roller brush 6 and has at least one group of second bristles 9 in the circumferential direction. When the cleaning component is working, the first roller brush 6 rotates so that the first bristles 7 sweep the garbage on the surface to be cleaned to the second roller brush 8 and concentrate it near the channel 4. The second roller brush 8 rotates so that the second bristles 9 sweep the garbage on the surface to be cleaned to the first roller brush 6 and concentrate it near the channel 4.

[0067] The fan 5 generates suction when it is working. Since the fan 5 is connected to the first groove 3 through the channel 4, when the fan 5 generates suction, the garbage gathered below the first groove 3 can be sucked into the garbage bin 21 through the channel 4 for collection.

[0068] It should be noted that the direction in which the housing 1 moves along the surface to be cleaned is the front, and the opposite direction is the rear. Fig.10As shown, the first roller brush 6 is located in the front and rotates clockwise, and the second roller brush 8 is located in the rear and rotates counterclockwise. The two rotate in opposite directions so that the garbage is concentrated between the first roller brush 6 and the second roller brush 8 and located near the channel 4 for easy collection.

[0069] Currently, there are many forms of cleaning components. One of them is to clean with water and a roller brush. Although this cleaning method has a good cleaning effect, it requires carrying a water tank. The water tank is heavy, which will increase the weight of the cleaning component, thereby increasing energy consumption and reducing working time. Another method is to clean with a single roller brush. This method can only move the garbage forward or backward during cleaning. The garbage is more scattered during cleaning, and some garbage cannot be collected, resulting in poor cleaning effect.

[0070] When the cleaning component provided in this embodiment is used for cleaning, dust and other garbage on the surface to be cleaned enters the channel 4 under the sweeping of the first roller brush 6 and the second roller brush 8. The first roller brush 6 sweeps the garbage toward the second roller brush 8 and concentrates it near the channel 4. The second roller brush 8 sweeps the garbage toward the first roller brush 6 and concentrates it near the channel 4. The first roller brush 6 and the second roller brush 8 realize two-way cleaning of the garbage. During cleaning, the garbage is more concentrated between the first roller brush 6 and the second roller brush 8, that is, the garbage is more concentrated near the channel 4, which is convenient for collecting the garbage and makes the garbage cleaning effect better.

[0071] like Figures 3 to 5 As shown, in the cleaning component provided by this embodiment, the first bristles 7 are arranged in a V shape on the circumference of the first roller brush 6. When the first roller brush 6 rotates, the open end of the first bristles 7 moves toward the second roller brush 8, so that the first bristles 7 can sweep the garbage on the surface to be cleaned toward the second roller brush 8 and concentrate it near the channel 4; and / or, the second bristles 9 are arranged in a V shape on the circumference of the second roller brush 8. When the second roller brush 8 rotates, the open end of the second bristles 9 moves toward the first roller brush 6, so that the second bristles 9 can sweep the garbage on the surface to be cleaned toward the first roller brush 6 and concentrate it near the channel 4.

[0072] In this embodiment, the first bristles 7 and the second bristles 9 are both arranged in a V shape, and the arrangement directions of the first bristles 7 and the second bristles 9 are opposite. During the rotation of the bristles, the garbage on both sides can be moved along the bristles to the middle, and then concentrated at the closed end on the bristles, that is, the tip of the V-shaped bristles, and the open end is the end opposite to the closed end. Finally, the garbage is concentrated between the first roller brush 6 and the second roller brush 8, and at the same time concentrated on the closed ends of the first bristles 7 and the second bristles 9, making garbage collection more convenient.

[0073] like Figure 4 , Figure 5As shown, in the cleaning component provided by this embodiment, the closed end of the first bristle 7 is located near the channel 4; and / or, the closed end of the second bristle 9 is located near the channel 4, and the closed end is at the tip of the V-shaped bristle. In this embodiment, the closed end of the first bristle 7 and the closed end of the second bristle 9 are both located near the channel 4, and the garbage is very close to the channel 4, which makes it easier to collect the garbage when the fan 5 generates suction.

[0074] In the cleaning component provided in this embodiment, the first bristles 7 may include multiple groups, and the multiple groups of first bristles 7 are distributed on the first roller brush 6 along the axial direction of the first roller brush 6; the second bristles 9 may include multiple groups, and the multiple groups of second bristles 9 are distributed on the second roller brush 8 along the axial direction of the second roller brush 8; the channels 4 include multiple, at least one group of first bristles 7 and at least one group of second bristles 9 respectively correspond to the same channel 4.

[0075] Due to the large size of photovoltaic panels, in order to increase the cleaning efficiency of photovoltaic panels, the photovoltaic cleaning robot has a larger size. When the size of the photovoltaic cleaning robot is large, at least one group of first bristles 7 corresponds to a channel 4, and at least one group of second bristles 9 corresponds to a channel 4, which can increase the cleaning efficiency and cleaning effect of the photovoltaic cleaning robot on the photovoltaic panel.

[0076] like Figure 4 , Figure 5 As shown, in this embodiment, the first bristles 7 include 4 groups, the second bristles 9 include 4 groups and the channels 4 include two. The two closed ends of the two first bristles 7 and the two closed ends of the two second bristles 9 are located near the same channel 4. The movement distance of the garbage on the bristles is shorter and can be concentrated near the channel 4 more quickly, thereby improving the garbage collection efficiency and cleaning effect.

[0077] In the cleaning component provided in this embodiment, at least two groups of first bristles 7 are connected, and the axial length of the first bristles 7 after being connected is equal to the length of the first roller brush 6; and / or, at least two groups of second bristles 9 are connected, and the axial length of the second bristles 9 after being connected is equal to the length of the second roller brush 8.

[0078] like Figure 4 , Figure 5 As shown, in this embodiment, the axial length of the roller brush after the two groups of first bristles 7 are connected and the axial length of the roller brush after the two groups of second bristles 9 are connected are equal to the corresponding lengths of the roller brush. The bristles extend from one end to the other end of the roller brush, which can maximize the cleaning range and thus improve the cleaning efficiency.

[0079] like Figure 5 , Figure 6 , Figure 7 , Fig.11As shown, in the cleaning component provided in this embodiment, the cleaning component also includes a fourth motor 10, a sixth gear 11, a seventh gear 12, a third gear 13, a first transmission belt 14, a fourth gear 15, and a second transmission belt 16. The fourth motor 10 is arranged on the housing 1, the sixth gear 11 is arranged at one end of the first roller brush 6, the seventh gear 12 is arranged at one end of the second roller brush 8, the third gear 13 is arranged on the housing 1, the third gear 13 is connected to the rotating end of the fourth motor 10, the first transmission belt 14 is sleeved on the outer surfaces of the third gear 13 and the sixth gear 11, and the fourth gear 15 is arranged on the housing 1, the fourth gear 15 is meshed with the third gear 13, the second transmission belt 16 is sleeved on the outer surfaces of the seventh gear 12 and the fourth gear 15, and the third gear 13 is driven to rotate by the fourth motor 10. Since the third gear 13 is meshed with the fourth gear 15, the two rotate in opposite directions. The third gear 13 drives the sixth gear 11 to rotate through the first transmission belt 14, and then drives the first roller brush 6 to rotate. The fourth gear 15 drives the seventh gear 12 to rotate through the second transmission belt 16, and then drives the second roller brush 8 to roll, so as to realize the reverse rotation of the first roller brush 6 and the second roller brush 8.

[0080] Preferably, it also includes a fifth gear 17 and a third transmission belt 18, the fifth gear 17 is coaxially arranged with the third gear 13, the third transmission belt 18 is sleeved on the fifth gear 17 and the outer surface 17 of the rotating end of the fourth motor 10; and / or, a fan 19 is arranged on the fourth motor 10. In this embodiment, the fifth gear 17 and the fan 19 are simultaneously arranged on the fourth motor 10, the fifth gear 17 is connected to the fourth motor 10 through the third transmission belt 18, and the fan 19 can cool the fourth motor 10 to ensure the normal operation of the fourth motor 10. Of course, the fifth gear 17 can also be coaxially arranged with the third gear 13, or the fan 19 can be arranged on the fourth motor 10 alone.

[0081] In addition, as a first replaceable embodiment, the cleaning component also includes a first motor, a first gear and a second gear. The first motor is arranged on the shell 1, the first gear is arranged at one end of the first roller brush 6, the first gear is connected to the rotating end of the first motor, and the second gear is arranged at one end of the second roller brush 8. The second gear is meshed with the first gear. The first roller brush 6 is directly driven to rotate by the first motor. At the same time, since the first gear and the second gear are meshed, the second roller brush 8 rotates in the opposite direction.

[0082] In addition, as a second alternative embodiment, the cleaning component also includes a second motor and a third motor arranged on the shell 1, the rotating end of the second motor is connected to one end of the first roller brush 6, and the rotating end of the third motor is connected to one end of the second roller brush 8, and the roller brush is directly driven by the motor to rotate. The rotation directions of the second motor and the third motor are opposite, thereby driving the two roller brushes to rotate in opposite directions.

[0083] like Figure 8 , Fig. 9 As shown, in the cleaning component provided in this embodiment, the side wall of the shell 1 has a second groove 20; the cleaning component also includes: a trash bin 21, which is slidably arranged in the second groove 20, the trash bin 21 is connected to the channel 4, and the top or side wall of the trash bin 21 has a discharge port 22, and the discharge port 22 may be provided with a filter screen and / or filter cotton to filter the garbage, and the discharge port 22 is configured to connect the channel 4 and the fan 5. In this embodiment, the discharge port 22 is located at the top of the trash bin 21, and a magnet is provided on the side of the trash bin 21, and a magnet is also provided on the corresponding shell 1. The trash bin 21 is fixed by the mutual attraction between the magnets. When the trash bin 21 is taken out, it is only necessary to overcome the attraction between the magnets.

[0084] like Figure 4 , Figure 5 As shown, in the cleaning component provided in this embodiment, the cleaning component also includes: a fan 5, which is arranged on the shell 1, and the fan 5 is connected to the discharge port 22. Specifically, the air inlet end of the fan 5 is connected to the discharge port 22, and the air outlet end of the fan 5 is connected to the outside world. The rear side of the shell 1 has an opening, and the fan 5 is connected to the outside world through the opening on the shell 1. Under the action of the fan 5, the garbage enters the garbage bin 21 from the channel 4, and the garbage is collected by the garbage bin 21, and then the gas flows to the outside world through the fan 5.

[0085] like Figure 3 As shown, in the cleaning component provided in this embodiment, the cleaning component also includes: a plurality of support rollers 23, which are arranged at both ends of the bottom of the shell 1, and the plurality of support rollers 23 are located on both sides of the first roller brush 6 and the second roller brush 8. The support rollers 23 can roll along the cleaning surface to prevent friction between the shell 1 and the cleaning surface, while ensuring the distance between the bristles and the cleaning surface to prevent the bristles from failing to achieve a cleaning effect.

[0086] After the first roller brush 6 and the second roller brush 8 rotate at high speed, the first bristles 7, the second bristles 9, the shell 1 and the photovoltaic panel form a nearly sealed cavity, which, together with the negative pressure formed by the fan 5 in the first groove 3 and the dust collecting function of the first bristles 7 and the second bristles 9, can better suck the garbage into the dust box.

[0087] In addition, if Figure 1As shown, this embodiment also provides a photovoltaic cleaning robot, including: a body 24 and the cleaning component described in the above scheme, the cleaning component is arranged on the body 24, and the cleaning component is driven to move by the body 24. Since the cleaning component has two roller brushes, the two roller brushes can collect garbage in a centralized manner, thereby making the cleaning effect of the photovoltaic cleaning robot better.

[0088] The working principle of the photovoltaic cleaning robot provided in this embodiment is as follows:

[0089] During cleaning, the cleaning component is pushed to move by the body 24, and the supporting roller 23 rolls along the cleaning surface. The fourth motor 10 can drive the first roller brush 6 and the second roller brush 8 to rotate through the third gear 13 and the fourth gear 15. The two rotate in opposite directions. The first roller brush 6 rotates clockwise and the second roller brush 8 rotates counterclockwise. The rotation can drive the bristles to rotate. The bristles can sweep the garbage between the first roller brush 6 and the second roller brush 8 during the rotation process, and the garbage will move along the V-shaped bristles and concentrate at the closed end of the V-shaped bristles. Then, the garbage enters the garbage bin 21 along the channel 4 under the suction of the fan 5, and the garbage can be collected by the garbage bin 21.

[0090] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the scope of protection of the present utility model.
