Description

Technical Field

[0001] The utility model relates to the technical field of solar panels, and specifically provides a solar panel cleaning device. Background Art

[0002] Solar panels are devices that use sunlight to generate electricity directly and are usually installed outdoors. However, due to the precipitation of dust in the air and other reasons, there is often dust accumulation on the surface of solar panels, which will affect their absorption of sunlight and thus reduce their power generation efficiency. Therefore, in order to maintain the long-term and stable power generation of solar panels, regular cleaning and maintenance are essential.

[0003] At present, solar panels usually adopt the sliding rail type panel cleaning method. This method requires the integration of sliding rail type panel cleaning components on the solar panels. The cleaning components move on the rails to complete the cleaning of the solar panel surface. However, this cleaning method has some problems. First, the cleaning effect is not clear. Second, the sliding rail type panel cleaning method is suitable for centralized solar panels. For distributed solar panels, since the solar panels are relatively scattered, the cost of installing sliding rail type panel cleaning components on each solar panel is relatively high.

For those skilled in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0045] First combine Figure 1-4 The solar panel cleaning device of the present application is introduced.

[0046] like Figure 1-4 As shown, in order to solve the problem of how to improve the cleaning effect of solar panels while reducing costs. The solar panel cleaning device of the present application includes a spraying mechanism 2, a cleaning mechanism 1 and a driving mechanism. Among them, the cleaning mechanism 1 includes a base 11, a scraper 12 and a spray hole 111 arranged on the base 11. The spraying mechanism 2 is connected to the spray hole 111, and is configured to spray a cleaning liquid onto the solar panel through the spray hole 111. The output end of the driving mechanism is connected to the base 11, so as to drive the scraper 12 to move through the base 11 to clean the dirt on the solar panel.

[0047] In the present application, the spraying mechanism 2 can provide different cleaning liquids, which can be sprayed onto the surface of the solar panel through the spray hole 111, thereby facilitating the softening and decomposition of dirt on the surface of the solar panel. The scraper 12 of the cleaning mechanism 1 can move under the drive of the driving mechanism through the base, so that the dirt on the surface of the solar panel can be easily scraped off, thereby improving the cleaning effect of the solar panel. In addition, the integration of the spraying mechanism 2 and the cleaning mechanism 1 greatly improves the cleaning efficiency and optimizes the cleaning performance of the solar panel cleaning device. Compared with the traditional slide-type panel cleaning assembly, the present application does not need to be integrated on the solar panel, which solves the problem of high cleaning cost caused by installing a slide-type panel cleaning device on the solar panel, thereby showing higher economy and practicality.

[0048] Refer to the following Figure 1-4, a preferred embodiment of the solar panel cleaning device of the present application is introduced. Those skilled in the art will understand that the embodiments described below are only used to illustrate the principles of the present application and are not intended to limit the scope of protection of the present application. On the premise that the solar panel cleaning device at least includes a spraying mechanism 2, a cleaning mechanism 1 and a driving mechanism, those skilled in the art can adjust the following settings so that the present application can be applied to more specific application scenarios.

[0049] See also Figure 1-2 As shown, the solar panel cleaning device includes a spraying mechanism 2, a cleaning mechanism 1, a driving mechanism (not shown) and a connecting mechanism 3. The output end of the driving mechanism is connected to the connecting mechanism 3, and the cleaning mechanism 1 is arranged on the side of the connecting mechanism 3 away from the driving mechanism, so that the driving mechanism drives the connecting mechanism 3 to move while driving the cleaning mechanism 1 to clean the solar panel. The cleaning mechanism 1 is provided with a spray hole 111 connected to the spraying mechanism 2, so that the spraying mechanism 2 can spray different cleaning liquids to the solar panel through the spray hole 111 to improve the cleaning effect of the solar panel.

[0050] It should be noted that, in other preferred embodiments, the connection mechanism 3 is not necessary in the present application, and those skilled in the art can select it according to the setting requirements. In the case where the connection mechanism 3 is not provided, the driving mechanism is directly connected to the cleaning mechanism 1 to drive the cleaning mechanism 1 to move.

[0051] See next Figure 1-4 The cleaning mechanism 1 includes a substrate 11 and a scraper 12. The substrate 11 and the scraper 12 are both in the shape of long strips. Figure 4 The scraper 12 is provided on one side of the base 11 in the front-to-back direction (shown in the figure). The scraper 12 includes a scraper body 121 and a scraper head 122. The scraper body 121 is provided on one side of the base 11 in the height direction and extends along the length direction of the base 11 (shown in the figure). Figure 4 The scraper head 122 is arranged on one side of the scraper body 121 in the width direction (as shown in the left and right directions). Figure 4 The scraper head 122 is an upper or lower side shown in the figure and is away from one end of the base 11. The scraper head 122 extends along the length direction of the scraper body 121. The scraper head 122 is a double-layer tooth structure. The scraper head 122 of this structure can not only increase the scraping force of the scraper 12 and improve the cleaning efficiency of the solar cell panel, but also increase the durability of the scraper 12.

[0052] Of course, the specific arrangement of the scraper 12 is not fixed in the present application, and those skilled in the art can adjust it according to the arrangement requirements. For example, the scraper head 122 of the scraper 12 is arranged on the side of the scraper body 121 in the height direction and away from the base 11, or the scraper head 122 of the scraper 12 is arranged on both sides in the width direction of the scraper 12. And / or, the scraper head 122 can be a single-layer tooth structure, or a three-layer or other number of layers of tooth structure.

[0053] See next Figure 2-4 , guide plates 13 are respectively provided on both sides of the base 11 in the length direction of the scraper 12, and the two guide plates 13 extend along the length direction of the base 11, and each guide plate 13 forms a drainage groove 131 with the base 11 and the scraper 12. Specifically, the side of the guide plate 13 facing the plug plate, the side of the base 11 provided with the scraper 12, and the side of the scraper 12 facing the guide plate 13 together form the drainage groove 131, so that the dirt scraped by the scraper 12 can be discharged through the drainage groove 131. The side of the guide plate 13 facing the scraper 12 is an inclined surface 132, which is inclined in the direction away from the scraper 12, so that the dirt scraped by the scraper 12 can be guided to the drainage groove 131 for discharge under the action of the guide plate 13.

[0054] Of course, the number of drainage grooves 131 provided in the present application is not fixed, and those skilled in the art can adjust it according to the needs of the settings. For example, the number of drainage grooves 131 provided can be 1. When the number of drainage grooves 131 provided is 1, the guide plate 13 is only provided on one side of the base 11 in the length direction of the scraper 12. In addition, the formation method of the drainage grooves 131 in the present application is not fixed, and those skilled in the art can adjust it according to the specific application scenario. For example, one or both sides of the base 11 in the length direction of the scraper 12 are recessed in the height direction away from the scraper 12 to form the drainage grooves 131.

[0055] In addition, the specific form of the inclined surface 132 on the guide plate 13 is not fixed in this application, and those skilled in the art can make adjustments as needed. For example, the guide plate 13 is tilted along the base 11 in the direction away from the scraper 12, that is, the side of the guide plate 13 facing the scraper 12 and the side away from the scraper 12 are both inclined surfaces 132. Alternatively, the part of the guide plate 13 close to the scraper 12 is the inclined surface 132, wherein the side of the guide plate 13 close to the scraper 12 can include two parts, namely a straight surface and an inclined surface 132, the part of the guide plate 13 away from the base 11 is the inclined surface 132, and the part close to the base 11 is a straight surface perpendicular to the base 11, which is also conducive to guiding the dirt scraped by the scraper 12 to the drainage groove 131 for discharge. Alternatively, the portion of the guide plate 13 on one side close to the scraper 12 is a slope 132, wherein the slope 132 may include two parts, the portion close to the base 11 is inclined toward the direction close to the scraper 12, and the portion away from the base 11 is inclined toward the direction away from the scraper 12, which is also beneficial for the dirt scraped by the scraper 12 to be guided to the drainage groove 131 for discharge under its action.

[0056] In addition, the specific setting form of the guide plate 13 is not fixed in the present application, and those skilled in the art can adjust it according to the situation. For example, the side of the guide plate 13 facing the scraper 12 is a curved surface, and the curved surface is convex or concave in the direction away from the scraper 12, which is conducive to guiding the dirt scraped by the scraper 12 to the drainage groove 131 under its action. When the side of the guide plate 13 facing the scraper 12 is a curved surface, the side away from the scraper 12 can be a curved surface, or the part of the side of the guide plate 13 facing the scraper 12 can be a curved surface, such as the side of the guide plate 13 facing the scraper 12 can include two parts, namely a curved surface and a straight surface, the part of the guide plate 13 away from the base 11 is a curved surface, and the part close to the base 11 is a straight surface perpendicular to the base 11. Alternatively, the portion of the guide plate 13 on one side close to the scraper 12 is a curved surface, wherein the curved surface may include two parts, the portion close to the base 11 is convex or concave toward the direction close to the scraper 12, and the portion away from the base 11 is convex or concave toward the direction away from the scraper 12, which is also beneficial for the dirt scraped by the scraper 12 to be guided to the drainage groove 131 for discharge under its action.

[0057] See next Figure 1The spraying mechanism 2 includes two liquid storage tanks 21, and the two liquid storage tanks 21 contain different cleaning liquids, that is, one liquid storage tank 21 contains cleaning water, and the other liquid storage tank 21 contains washing liquid. A plurality of spray holes 111 are provided on the base 11 between the scraper 12 and the guide plate 13, and each spray hole 111 is installed with a nozzle 23. These spray holes 111 are divided into two groups, one group is connected to the liquid storage tank 21 containing cleaning water through a pipeline, and the other group is connected to the liquid storage tank 21 containing washing liquid through a pipeline, so that the nozzle 23 installed in the spray hole 111 can spray the cleaning liquid to the solar panel. When cleaning the dirt on the surface of the solar panel, the cleaning liquid can be sprayed on the surface of the solar panel through the spraying mechanism 2, and the dirt on the surface of the solar panel can be softened and decomposed by the detergent. The softened dirt on the surface of the solar panel can then be cleaned by the cleaning mechanism 1, and then cleaning water can be sprayed on the surface of the solar panel. Finally, the dirt on the surface of the solar panel can be cleaned by the cleaning mechanism 1. This cleaning method can improve the cleaning effect of the solar panel.

[0058] Of course, the present application does not limit the specific type of cleaning liquid in the n liquid storage tanks 21, as long as the cleaning liquid is conducive to softening or decomposing the dirt on the surface of the solar panel. For example, the same cleaning liquid, such as water or detergent, can be contained in the n liquid storage tanks 21. In addition, the present application does not have a fixed number of liquid storage tanks 21, and those skilled in the art can adjust it according to the needs of the setting. For example, the number of liquid storage tanks 21 can be 3 or other numbers. Taking the number of 3 liquid storage tanks 21 as an example, the three liquid storage tanks 21 can contain different cleaning liquids from each other, or any two of the three liquid storage tanks 21 can contain the same cleaning liquid, and the third liquid storage tank 21 can contain a cleaning liquid different from the former, or the three liquid storage tanks 21 can contain the same cleaning liquid.

[0059] In addition, the arrangement of the spray holes 111 in the present application is not fixed, and those skilled in the art can adjust it according to specific application scenarios. For example, at least one spray hole 111 is arranged on the base 11, and each spray hole 111 is connected to two liquid storage tanks 21. When it is necessary to spray clean water onto the solar panel, the liquid storage tank 21 containing clean water can spray the clean water onto the solar panel through the nozzles 23 installed on these spray holes 111. When it is necessary to spray washing liquid onto the solar panel, the liquid storage tank 21 containing washing liquid can spray the washing liquid onto the solar panel through the nozzles 23 installed on these spray holes 111.

[0060] See next Figure 1-3The connection mechanism 3 includes a connection rod 31, a connector 32, a transmission mechanism 33 and a base 34. The connection rod 31 is provided with a connector 32 at one end and a transmission mechanism 33 at the other end. The connector 32 includes a rotating shaft 323, a first connecting plate 321 and a second connecting plate 322. The first connecting plate 321 is provided with a second connecting plate 322 on one side and a connection rod 31 on the other side. The second connecting plate 322 and the connection rod 31 are provided on the opposite side of the first connecting plate. The base 11 and the connection rod 31 are provided on the same side of the second connecting plate 322, and one side of the width direction of the base 11 is connected to the second connecting plate 322 through the rotating shaft 323. There is a gap between the side of the base 11 away from the scraper 12 and the side of the first connecting plate 321 away from the connection rod 31, so that the base 11 can rotate, thereby adjusting the angle of the scraper 12 and improving the cleaning effect of the solar panel.

[0061] Of course, the configuration of the connector 32 in the present application is not fixed, and those skilled in the art can make adjustments according to the configuration requirements. For example, the connector 32 only includes the first connecting plate 321 or the second connecting plate 322. When the connector 32 only includes the first connecting plate 321, one side of the first connecting plate 321 is fixedly connected to the connecting rod 31, and the other side can be rotatably connected to the base 11 through the rotating shaft 323. The connecting rod 31 and the base 11 are arranged on opposite sides of the first connecting plate 321, and the angle of the scraper 12 can also be adjusted. When the connector 32 only includes the second connecting plate 322, one side of the second connecting plate 322 is rotatably connected to the base 11 through the rotating shaft 323, and the adjacent side is fixedly connected to the connecting rod 31.

[0062] See next Figure 1-2 , the connecting rod 31 is a telescopic rod. By setting the connecting rod 31 as a telescopic rod, the fitting effect between the scraper 12 and the solar panel can be improved. The connecting rod 31 is a hollow structure, and its internal space can be used for the pipeline connecting the liquid storage tank 21 and the injection hole 111. This arrangement simplifies the pipeline wiring problem by utilizing the internal space of the connecting rod 31. And part of the connecting rod 31 is inclined from the connection with the first connecting plate 321 to the side where the scraper head 122 on the scraper 12 is located, so as to facilitate the application of force to the cleaning mechanism and improve the fitting effect between the scraper head 122 on the scraper and the solar panel. One end of the transmission mechanism 33 is connected to the connecting rod 31, and the other end is connected to the driving mechanism through the base 34, so that the driving mechanism can drive the scraper 12 to move while driving the transmission mechanism 33 to move, thereby scraping off the dirt on the solar panel.

[0063] It should be noted that, in other preferred embodiments, the base 34 and / or the transmission mechanism 33 are not necessarily provided, and those skilled in the art can select them according to the needs of the settings. In the case where the base 34 is not provided, the driving mechanism is directly connected to the transmission mechanism 33. In the case where the base 34 and the transmission mechanism 33 are not provided, the driving mechanism is a telescopic mechanism, which is directly connected to the connecting rod 31. It should also be noted that the present application has no restrictions on the specific structure of the transmission mechanism 33, as long as the transmission mechanism 33 can drive the cleaning mechanism 1 to move under the drive of the driving mechanism.

[0064] Of course, the setting form of the connecting rod 31 in the present application is not fixed, and those skilled in the art can adjust it according to the setting needs. For example, the connecting rod 31 as a whole is inclined from the connection with the first connecting plate 321 to the side where the scraper head 122 on the scraper 12 is located. Alternatively, part of the connecting rod 31 is bent from the connection with the first connecting plate 321 to the side where the scraper head 122 on the scraper 12 is located. Alternatively, the connecting rod 31 as a whole is bent from the connection with the first connecting plate 321 to the side where the scraper head 122 on the scraper 12 is located.
