Examples

In the cleaning process of the photovoltaic panels of the existing centralized photovoltaic power station, due to the influence of terrain environment, the height difference of the photovoltaic panels causes the insufficient stability and reliability of the cleaning robot in the working process, in order to further improve the efficiency of the cleaning robot in the cleaning process of the photovoltaic panels of the centralized photovoltaic power station and reduce the input cost of cleaning equipment, as shown in the attached figure 1, the embodiment provides a photovoltaic panel cleaning system which comprises a line changing system a and a cleaning robot b, wherein the line changing system a comprises a line changing vehicle a1 and a ground track a2, the ground track a2 is paved on one side of a row of photovoltaic panel display c arranged side by side for the line changing vehicle a1 to walk, the cleaning robot b can move onto the line changing vehicle a1 and is carried by the line changing vehicle a1 to walk on the ground track a2, so that the line of the parallel arranged photovoltaic panel arrays c can be transported, and the line of the parallel arranged photovoltaic panel arrays c can be cleaned, wherein the cleaning robot b is provided with a vertical cross floating transmission mechanism b1 for ensuring that the cleaning robot b can walk smoothly in the moving process of the line of the parallel arranged photovoltaic panel arrays c, as shown in figures 2a,2b,2c,2d,2e,2f and 2 g. When the cleaning robot cleans a row of photovoltaic plate groups, due to the constraint of a terrain environment, the photovoltaic plate groups cannot be flat, various installation angles and the requirements of the photovoltaic plate array on the misplacement, the height difference and the gradient difference exist, the existing cleaning robot is difficult to span a slope with a larger angle and the misplacement, the height difference and the gradient difference of the photovoltaic plate array edge through the driving force of the existing cleaning robot, and after the vertical cross floating transmission mechanism is installed on the cleaning robot, the elastic force of the vertical cross floating transmission mechanism can be used as an auxiliary wheel of the cleaning robot, so that the cleaning robot can smoothly pass through the slope with a larger angle and the misplacement, the gradient difference of the photovoltaic plate array edge, Height difference and gradient difference. Meanwhile, in order to adapt to the existing photovoltaic panels with different lengths, in the embodiment, the cleaning robot b adopts a modularized structure, so that different lengths can be selected according to the lengths of the photovoltaic panels. Further, the problem to be solved in this embodiment is that the existing cleaning robot has a centrally installed cleaning brush, that is, the cleaning brush is located between two driving wheels of the device, and since the edge of the photovoltaic panel array corresponding to the installation portion of the cleaning brush installed on the cleaning robot is difficult to clean, in order to clean completely, the driving wheel must exceed the edge of the end of the photovoltaic panel, therefore, a parking frame with a complicated installation construction and a long period must be installed at the end of each row of photovoltaic panel array, so as to ensure that the cleaning brush can clean the whole area of the photovoltaic panel array. Each row is provided with a parking frame, and the equipment investment cost of the whole power station is huge. The main brush assembly b2 of the cleaning robot b in the present embodiment is disposed at the front side of the cleaning robot b to expand the cleaning area to avoid missing the cleaning.

Specifically, when the cleaning robot works on the centralized photovoltaic panel array with the photovoltaic panel installation angle (the included angle with the ground) being more than or equal to 25 degrees, the driving force of the driving wheel b10401 is suddenly reduced due to the fact that the driving force of the driving wheel b10401 is reduced due to the fact that the friction force of the driving wheel b10401 is reduced to the light Fu Banya, at the moment, the pressure on the auxiliary wheel assembly b106 is increased, the friction force is increased, the driving force is increased, and the situation of insufficient driving force caused by the fact that the driving force of the driving wheel b10401 is reduced is overcome.

The whole photovoltaic panel cleaning system realizes intellectualization, modularization, standardization and serialization, so that the production cost and the production period of the whole equipment are greatly reduced and shortened; the construction difficulty is reduced during field installation, and the construction period is shortened; meanwhile, intelligent control and automatic operation are realized when the photovoltaic panel cleaning system is operated, personnel are not required to operate on site or in the background, and the unattended requirement is realized.

The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.

The foregoing examples illustrate only a few embodiments of the application and are described in detail herein without thereby limiting the scope of the application. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the application, which are all within the scope of the application. Accordingly, the scope of protection of the present application is to be determined by the appended claims.
