However, photovoltaic panels are exposed to the outdoor environment for a long time and are easily affected by pollutants such as dust, bird droppings and snow, which greatly reduces their power generation efficiency. Therefore, it is particularly important to clean photovoltaic panels regularly. At present, the common cleaning method mainly uses brush cleaning systems, which mechanically remove dust, bird droppings and snow from the surface of photovoltaic panels. However, in actual application, the brush cleaning system may cause wear on the surface of the photovoltaic panel, thereby affecting the service life of the photovoltaic panel.

It should be noted that when a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a centrally arranged component at the same time.

[0022] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0023] The embodiment of the present invention provides a photovoltaic cleaning mechanical device 100 .

[0024] See also Figures 1 to 9 In one embodiment of the present invention, the photovoltaic cleaning mechanical device 100 comprises: The frame body 110 is used for being movably mounted on two sides of the photovoltaic panel 200; A cleaning assembly 120, the cleaning assembly 120 comprising a first driving mechanism 121 connected to the frame body 110, a mounting frame 122 matched with the first driving mechanism 121, a first brush plate 123 and a second brush plate 124 respectively mounted on the mounting frame 122 and located on both sides of the first driving mechanism 121, and a second driving mechanism 125 for driving the first brush plate 123 and the second brush plate 124 to rotate; The first driving mechanism 121 is used to drive the mounting frame 122 to move toward the two side surfaces of the photovoltaic panel 200 respectively; the cleaning assembly 120 also includes a first support rod 126 and a second support rod 127 arranged along the driving direction of the first driving mechanism 121 and respectively arranged on both sides of the first driving mechanism 121; the mounting frame 122 is respectively formed with a first opening groove 122a and a second opening groove 122b that slides with the first support rod 126 and the second support rod 127; the outer dimensions of the first opening groove 122a and the second opening groove 122b are larger than the first support rod 126 and the second support rod 127, so that the first support rod 126 has a movable space relative to the first opening groove 122a, and the second support rod 127 has a movable space relative to the second opening groove 122b; when the first brush plate 123 or the second brush plate 124 passes through the protruding structure on the photovoltaic panel 200, the height of the first brush plate 123 or the second brush plate 124 relative to the photovoltaic panel 200 can be adaptively adjusted.

[0025] It can be understood that the technical solution of the present invention is used to clean the photovoltaic panel 200 by setting a cleaning assembly 120 composed of a first driving mechanism 121, a mounting frame 122, a first brush disc 123, a second brush disc 124 and a second driving mechanism 125. Specifically, in the technical solution of this embodiment, the second driving assembly drives the first brush disc 123 and the second brush disc 124 to rotate, thereby effectively cleaning the stains on the photovoltaic panel 200. Furthermore, by providing a first driving assembly to drive the mounting frame 122 to move toward the two side surfaces of the photovoltaic panel 200 respectively, automatic displacement is achieved during the cleaning process, thereby improving the cleaning efficiency.

[0026] Further, in the technical solution of this embodiment, the mounting frame 122 is further provided with a first opening slot 122a and a second opening slot 122b, and the cleaning assembly 120 further includes a first support rod 126 and a second support rod 127 which are arranged along the driving direction of the first driving mechanism 121 and are respectively arranged on both sides of the first driving mechanism 121, the first support member is slidably matched with the first opening slot 122a; the second support rod 127 is slidably matched with the second opening slot 122b, and the outer dimensions of the first opening slot 122a and the second opening slot 122b are larger than those of the first support rod 126 and the second support rod 127, so that The first support rod 126 has a movable space relative to the first opening slot 122a, and the second support rod 127 has a movable space relative to the second opening slot 122b; when the first brush disc 123 or the second brush disc 124 passes through the protruding structure on the photovoltaic panel 200, the first brush disc 123 and the second brush disc 124 have a seesaw effect relative to the first driving mechanism 121, and after the first brush disc 123 is away from the photovoltaic panel 200, the second brush disc 124 approaches the photovoltaic panel 200; or after the second brush disc 124 is away from the photovoltaic panel 200, the first brush disc 123 approaches the photovoltaic panel 200. Thus, the height of the first brush disc 123 or the second brush disc 124 relative to the photovoltaic panel 200 can be adaptively adjusted; the first brush disc 123 or the second brush disc 124 is prevented from excessively cleaning the protruding structure, thereby reducing excessive wear of the first brush disc 123 or the second brush disc 124 on the surface of the photovoltaic panel 200.

[0027] It should also be noted that the protruding structure on the photovoltaic panel 200 may be block-shaped stains or bird droppings or other protruding parts.

[0028] It should also be noted that after the first brush disc 123 or the second brush disc 124 is away from the photovoltaic panel 200 , the bristles on the first brush disc 123 and the second brush disc 124 can still effectively clean the protruding structure.

[0029] Furthermore, the first brush plate 123 and the second brush plate 124 are disposed on both sides of the first driving mechanism 121 , thereby widening the cleaning area of ​​the cleaning assembly 120 , thereby further achieving efficient cleaning.

[0030] Optionally, the first driving mechanism 121 may be a screw motor linear driving mechanism, or a belt drive linear driving mechanism.

[0031] Alternatively, if Figure 6As shown, the second driving mechanism 125 is a belt drive mechanism. It can be understood that the belt drive mechanism can make the first brush plate 123 and the second brush plate 124 rotate simultaneously, thereby reducing the weight of the cleaning component 120 and reducing the driving cost.

[0032] See also Figure 2 and Figure 3 In a specific embodiment, the first brush plate 123 and the second brush plate 124 are at the same distance from the first driving mechanism 121 , and the straight direction of the first brush plate 123 and the second brush plate 124 forms an acute angle with the driving direction of the first driving mechanism 121 .

[0033] It can be understood that if the first brush disc 123 and the second brush disc 124 are at the same distance from the first drive mechanism 121, then the adaptively adjusted spacings of the first brush disc 123 and the second brush disc 124 are the same. Furthermore, the straight line direction of the first brush disc 123 and the second brush disc 124 forms an acute angle with the driving direction of the first drive mechanism 121, which can avoid the protruding structure on the photovoltaic panel 200 from acting on the first brush disc 123 and the second brush disc 124 at the same time, avoid the device from getting stuck, and improve the stability and reliability of the device operation.

[0034] See also Figure 4 In a preferred embodiment, the first brush plate 123 and the second brush plate 124 are respectively provided with a first elastic member 128 relative to the mounting frame 122, and during the rotation of the first brush plate 123 or the second brush plate 124, the first elastic member 128 can autonomously perform elastic contraction and elastic recovery.

[0035] It can be understood that the provision of the first elastic member 128 can further reduce excessive wear on the photovoltaic panel 200 .

[0036] Please continue reading Figure 3 In a specific embodiment, the first brush plate 123 is close to the installation ground of the photovoltaic panel 200 , and the bristles of the second brush plate 124 are softer than those of the first brush plate 123 .

[0037] It can be understood that the bristles of the second brush plate 124 are softer than those of the first brush plate 123, that is, the first brush plate 123 has a greater cleaning force when cleaning stains on the photovoltaic panel 200. Therefore, the first brush plate 123 is more likely to move away from the photovoltaic panel 200 during the adaptive adjustment process. However, the bristles on the second brush plate 124 are softer. Therefore, after the first brush plate 123 moves away from the photovoltaic panel 200, the second brush plate 124 can move close to the photovoltaic panel 200 for cleaning, thereby improving the cleaning effect.

[0038] Optionally, the bristles on the first brush plate 123 are nylon columns, and the bristles on the second brush plate 124 are animal hair.

[0039] See also Figure 5 and Figure 6 In a specific embodiment of the present invention, the mounting frame 122 includes a matching portion 1221 connected to the first driving mechanism 121, and a first mounting portion 1223 and a second mounting portion 1224 which are respectively arranged on both sides of the first driving mechanism 121 and connected to the matching portion 1221, and the first mounting portion 1223 and the second mounting portion 1224 are symmetrical relative to the center of the matching portion 1221.

[0040] It can be understood that the arrangement of the first mounting portion 1223 and the second mounting portion 1224 can balance the counterweight of the mounting frame 122 and improve the stability of the device operation.

[0041] See also Figure 5 , Figure 6 and Figure 7 In a specific embodiment of the present invention, the rack body 110 is provided with a first positioning member 111 and a second positioning member 112, the first mounting portion 1223 is provided with a first limit switch 131, and the second mounting portion 1224 is provided with a second limit switch 132; when the first driving mechanism 121 drives the matching portion 1221 to move close to one side of the rack body 110, the first positioning member 111 can be used to trigger the first limit switch 131, or the second positioning member 112 can be used to trigger the second limit switch 132.

[0042] It can be understood that the arrangement of the first limit switch 131 and the second limit switch 132 can prevent the first mounting portion 1223 or the second mounting portion 1224 from colliding with the rack body 110. The first limit switch 131 and the second limit switch 132 can control the first driving member so that the first driving member switches the working direction in time.

[0043] For further information, see Figure 7 , Figure 8 and Fig. 9 In a specific embodiment, the rack body 110 is further provided with a first anti-collision component 113 and a second anti-collision component 114, the first anti-collision component 113 is used to contact with the side wall of the first mounting portion 1223 to reduce the impact force of the first mounting portion 1223 on the rack body 110; the second anti-collision component 114 is used to contact with the side wall of the second mounting portion 1224 to reduce the impact force of the second mounting portion 1224 on the rack body 110.

[0044] Specifically, the first anti-collision component 113 and the second anti-collision component 114 each include a fixing member 1131, a second elastic member 1132 and a movable member 1133; the fixing member 1131 is connected to the frame body 110, the movable member 1133 is embedded in the fixing member 1131, and the second elastic member 1132 abuts against the frame body 110 and the movable member 1133 respectively; when the movable member 1133 is impacted, the second elastic member 1132 can absorb the impact potential energy of the movable member 1133, thereby reducing the impact on the frame body 110 or the first driving mechanism 121 itself.

[0045] Optionally, the first anti-collision component 113 and the second anti-collision component 114 may also be rubber pads or silicone pads to prevent the first mounting portion 1223 or the second mounting portion from excessively impacting the rack body 110 .

[0046] See also Figure 1 or Figure 2 In a specific embodiment, the photovoltaic cleaning mechanical device 100 further includes a third driving mechanism 140 , which is fixedly connected to the photovoltaic panel 200 and is used to drive the frame body 110 to move along the extension direction of both side edges of the photovoltaic panel 200 .

[0047] Specifically, the third driving mechanism 140 is a belt transmission mechanism, and a belt in the belt transmission mechanism is fixedly connected to the frame body 110 .

[0048] Optionally, one end of the first driving mechanism 121, the first support rod 126, and the second support rod 127 are all movably connected to the frame body 110, so that the photovoltaic cleaning mechanical device 100 can be adapted to photovoltaic panels 200 of different lengths or widths.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features thereof may be replaced by equivalents.
