DETAILED DESCRIPTION

[0056] In the embodiments of the present application, the words "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs.

[0058] As mentioned in the background technology, photovoltaic panels are devices that absorb sunlight and convert solar radiation directly or indirectly into electrical energy. When photovoltaic panels are placed outdoors for a long time, a large amount of dust will accumulate on their outer surface, which will reduce the power generation efficiency of the photovoltaic panels, affect the life of the photovoltaic panels and even cause safety hazards. Therefore, it is necessary to clean the photovoltaic panels regularly. At present, the existing photovoltaic panel cleaning technology is generally carried out manually, and the operator directly holds a high-pressure water gun to spray and clean the outer surface of the photovoltaic panel. However, the above method for cleaning photovoltaic panels not only has low cleaning efficiency, but also poor cleaning effect.

[0059] Based on this, the present application provides a photovoltaic panel cleaning device, which includes a moving mechanism, a cleaning mechanism and a water supply mechanism, wherein the cleaning mechanism includes a first driving member, a transmission rod group and a plurality of cleaning brush discs.

[0060] When the surface of the photovoltaic panel is covered with stains, the staff only needs to place the cleaning device on the surface of the photovoltaic panel. At this time, the water supply mechanism will evenly spray the cleaning liquid stored in the cleaning device onto the surface of the photovoltaic panel. Then, the first driving member and the moving mechanism respectively drive each cleaning brush disc to rotate and move relative to the photovoltaic panel through the transmission rod group, and use the friction generated when the cleaning brush disc rotates and moves relative to the photovoltaic panel, in conjunction with the cleaning effect of the cleaning liquid itself, to complete the cleaning operation of the photovoltaic panel surface. Therefore, the present application realizes automatic cleaning of the photovoltaic panel surface through the cooperation between the moving mechanism, the cleaning mechanism and the water supply mechanism, thereby improving the working efficiency of cleaning the photovoltaic panel.

[0061] The technical solution of the present application is described in detail below with reference to the accompanying drawings using specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0062] Reference Figures 1 to 3 As shown, an embodiment of the present application provides a photovoltaic panel cleaning device, including a moving mechanism 100, a cleaning mechanism 200 and a water supply mechanism; the cleaning mechanism 200 includes a first driving member 210, a transmission rod group and a plurality of cleaning brush discs 230, each cleaning brush disc 230 is arranged at intervals along the extension direction of the transmission rod group, and each cleaning brush disc 230 is used to contact the surface of the photovoltaic panel respectively, the first driving member 210 is installed in the moving mechanism 100, and the driving end of the first driving member 210 is connected to the transmission rod group to drive each cleaning brush disc 230 to rotate relative to the photovoltaic panel through the transmission rod group, and the moving mechanism 100 drives the cleaning brush disc 230 to move through the transmission rod group to clean the surface of the photovoltaic panel; the water supply mechanism is arranged on the moving mechanism 100, for storing cleaning fluid and providing cleaning fluid to the photovoltaic panel.

[0063] It should be noted that, in the present application, there is no restriction on the arrangement of each cleaning brush disc 230 on the transmission rod group, that is, the number of each cleaning brush disc 230 and the arrangement density on the transmission rod group can be adjusted according to the actual scenario to ensure that there are no cleaning dead corners between the cleaning brush discs 230.

[0064] In the present application, when the surface of the photovoltaic panel is covered with stains, the staff only needs to place the cleaning device on the photovoltaic panel. At this time, the water supply mechanism will evenly spray the cleaning liquid stored in the cleaning device onto the surface of the photovoltaic panel. Then, the first driving member 210 and the moving mechanism 100 respectively drive each cleaning brush disc 230 to rotate and move relative to the photovoltaic panel through the transmission rod group. The friction generated when the cleaning brush disc 230 rotates and moves relative to the photovoltaic panel is used, and the cleaning effect of the cleaning liquid itself is combined to make the stains fall off the surface of the photovoltaic panel, thereby completing the cleaning operation of the photovoltaic panel surface. Therefore, the present application realizes automatic cleaning of the photovoltaic panel surface through the cooperation between the moving mechanism 100, the cleaning mechanism 200 and the water supply mechanism, thereby improving the working efficiency of cleaning the photovoltaic panel.

[0065] Reference Figure 2 As shown, in some embodiments, the transmission rod group includes at least two transmission shafts 220, each transmission shaft 220 is meshingly connected, and at least one transmission shaft 220 is provided with a cleaning brush disc; one of the transmission shafts 220 is connected to the driving end of the first driving member 210 to drive each transmission shaft 220 to rotate around its own axis in turn, thereby driving each cleaning brush disc to rotate relative to the photovoltaic panel.

[0066] Because the cleaning brush disc 230 is driven by the moving mechanism 100 and is always in a moving state on the photovoltaic panel, the time for the cleaning brush disc 230 to scrub each position on the photovoltaic panel surface is relatively short, and it is inevitable that stains will remain. In order to avoid the need for workers to rework multiple times, in the embodiment of the present application, at least two transmission shafts 220 are provided, and a cleaning brush disc 230 is provided on at least one transmission shaft 220, so as to achieve multi-layer cleaning of the photovoltaic panel surface, thereby ensuring the cleaning effect of the cleaning device.

[0067] Furthermore, in some embodiments, each transmission shaft 220 is a gear shaft; a first gear part 221 is inserted on the transmission shaft 220 corresponding to the cleaning brush disc 230, and the cleaning brush disc 230 includes a second gear part 231, a connecting rod 232 and a brush disc body 233. The second gear part 231 is connected to the brush disc body 233 through the connecting rod 232, and the second gear part is meshed with the first gear part, and the connecting rod is inserted on the moving mechanism.

[0068] In a specific implementation, the connection between the brush plate body 233 and the connecting rod 232 needs to be set as a detachable connection so that the brush plate body 233 can be replaced at any time, thereby ensuring the cleaning effect of the cleaning device.

[0069] It is understandable that in the present application, there is no restriction on the specific transmission method between the transmission shaft 220 and the cleaning brush disc 230, as long as it can ensure that the transmission shaft 220 can drive the cleaning brush disc to rotate relative to the photovoltaic panel. Specifically, in the embodiment of the present application, the transmission shaft 220 and the cleaning brush disc 230 are driven by gear meshing, which not only facilitates the assembly between the transmission shaft 220 and the cleaning brush disc 230, but also enables reliable transmission between the transmission shaft 220 and the cleaning brush disc 230, thereby driving each cleaning brush disc 230 to rotate relative to the photovoltaic panel.

[0070] Furthermore, in some embodiments, a rubber brush is disposed on the end surface of the brush plate body 233 facing the photovoltaic panel.

[0071] Here, a rubber brush is arranged on the brush plate body 233. Compared with ordinary soft-bristle brushes, rubber brushes are not only easy to clean and not easily stained, but also stronger than soft-bristle brushes, so rubber brushes can more effectively remove stains that are firmly adhered to the surface of the photovoltaic panel.

[0072] Reference Figure 1 As shown, in some embodiments, the mobile mechanism 100 includes a carrying body 110 and a driving assembly, and a first driving member 210 is installed in the carrying body 110; the driving assembly includes at least four wheels 120, and the wheels 120 are rotatably arranged on the carrying body 110, so as to drive any wheel 120 to rotate relative to the carrying body 110, thereby moving the carrying body 110 on the surface of the photovoltaic panel.

[0073] In a specific implementation, the mobile mechanism 100 moves on the surface of the photovoltaic panel by means of a driving assembly. The wheel 120 is rotatably arranged on the bearing body 110. Since the surface of the photovoltaic panel is relatively smooth and the photovoltaic panel is generally placed at an angle, the tire of the wheel 120 needs to be made of a material with a large friction coefficient to ensure that the cleaning device does not slip off the photovoltaic panel. The driving member can be a motor, etc., and this application does not limit this. The driving member drives the wheel 120 to rotate so that the bearing body 110 moves on the surface of the photovoltaic panel.

[0074] Reference Figure 2 As shown, in some embodiments, the moving mechanism 100 further includes at least two sliding assemblies 130 , each sliding assembly 130 is respectively disposed on two opposite sides of the bearing body 110 , and the sliding assembly 130 is used for sliding connection with two sides of the photovoltaic panel.

[0075] It is understandable that, in the present application, there is no limitation on the spacing between the sliding assemblies 130 , and the spacing can be adjusted according to the actual width of the photovoltaic panel.

[0076] Here, by setting up the sliding component 130, on the one hand, it can play a limiting role on the cleaning device, further preventing the cleaning device from sliding off the photovoltaic panel; on the other hand, using the two sides of the photovoltaic panel as the running track of the cleaning device, the cleaning device can always keep moving on the center line of the photovoltaic panel to achieve cleaning without dead angles.

[0077] Furthermore, in some embodiments, the sliding assembly 130 includes a connecting plate 131, a rotating shaft 132 and a pulley 133. The connecting plate 131 is connected to the supporting body 110, the rotating shaft 132 is connected to the connecting plate 131, and the rotating shaft 132 and the connecting plate 131 are perpendicular to each other. The pulley 133 is rotatably disposed on the rotating shaft 132, and a sliding groove 133a is provided on the circumferential side thereof to engage with the side of the photovoltaic panel.

[0078] Here, a slide groove 133a is provided on the circumferential side of the pulley 133 to engage with the side of the photovoltaic panel, thereby improving the stability of the cleaning device moving on the surface of the photovoltaic panel.

[0079] Reference Figure 2 As shown, in some embodiments, the water supply mechanism includes a cleaning liquid storage tank and a water spray assembly 300. The cleaning liquid storage tank is installed in the supporting body 110 and is used to store cleaning liquid; the water spray assembly 300 includes a water pump 310 and a nozzle 320. The water pump 310 is connected to the cleaning liquid storage tank and the nozzle 320 respectively, so that the cleaning liquid in the cleaning liquid storage tank is output to the nozzle 320, and the cleaning liquid is sprayed on the surface of the photovoltaic panel.

[0080] In specific implementation, it is necessary to select a nozzle 320 with a smaller spray hole and a larger coverage area, so as to save the cleaning liquid and spray the cleaning liquid evenly on the surface of the photovoltaic panel.

[0081] Since it is difficult to effectively remove the stains firmly attached to the surface of the photovoltaic panel by relying solely on the friction force generated when the cleaning brush disc 230 rotates and moves relative to the photovoltaic panel, and the high-speed operation of the cleaning brush disc 230 can easily scratch the photovoltaic panel. Therefore, in the embodiment of the present application, by providing a cleaning liquid storage tank and a water spray assembly 300, combined with the cleaning effect of the cleaning liquid itself, the cleaning effect of the cleaning device can be effectively guaranteed, and the cleaning liquid can also form a lubricating layer between the cleaning brush disc 230 and the photovoltaic panel to reduce the wear of the cleaning brush disc 230 on the surface of the photovoltaic panel.

[0082] Reference Figure 2As shown, in some embodiments, a cleaning cloth 400 and two cantilevers 500 are also included. Each cantilever 500 is respectively extended and installed on two opposite sides of the supporting body 110, and is rotatably connected to the supporting body 110. The cleaning cloth 400 is sleeved between the two cantilevers 500, and the cleaning cloth 400 is used to wipe the residual cleaning liquid after brushing the surface of the photovoltaic panel.

[0083] In a specific implementation, the connection between the cleaning cloth 400 and each cantilever 500 needs to be set to a detachable connection, so that the cleaning cloth 400 can be replaced at any time to ensure the cleaning effect of the cleaning device. At the same time, each cantilever 500 is rotatably connected to the supporting body 110, so that the tightness of the contact between the cleaning cloth 400 and the photovoltaic panel can be adjusted.

[0084] Reference Figure 1 As shown, in some embodiments, a solar panel 600 is installed at the end of the carrier body 110 away from the photovoltaic panel; the first driving member 210 and the water supply mechanism are both electrically connected to a controller 700 installed in the carrier body 110.

[0085] Here, a solar panel 600 is provided to provide power for the operation of the cleaning device, and at the same time, clean energy is used to improve the environmental friendliness of the cleaning device.

[0086] It should be understood that the various forms of processes shown above can be used to reorder, add or delete steps. For example, the steps disclosed in this application can be performed in parallel, sequentially or in different orders, as long as the desired results of the technical solution disclosed in this application can be achieved, and this document does not limit this.

[0087] The above specific implementations do not constitute a limitation on the protection scope of this application. It should be understood by those skilled in the art that various modifications, combinations, sub-combinations and substitutions can be made according to design requirements and other factors. Any modification, equivalent substitution and improvement made within the principles of this application should be included in the protection scope of this application.
