As shown in fig. 1 to 4, in the prior art, the cleaning robot 1 is powered by a photovoltaic panel, but the photovoltaic panel for powering the cleaning robot 1 is generally designed integrally with the cleaning robot 1 and is mounted on the surface of the cleaning robot 1, so that cleaning is inconvenient. After dirt is accumulated on the photovoltaic panel supplying power to the cleaning robot 1, the power generation efficiency is reduced, and enough electric quantity cannot be provided for the cleaning robot 1, so that the cleaning robot 1 cannot complete cleaning work of the photovoltaic panel in the power station, and the power generation efficiency of the power station is reduced.
In order to solve the problems of dirt accumulation and reduced power generation efficiency of the photovoltaic panel supplying power to the cleaning robot 1, the power supply photovoltaic panel 4 supplying power to the cleaning robot 1 is arranged on the platform moving track 3 by adopting a scheme of separating the power supply photovoltaic panel 4 and the cleaning robot 1, and the sunlight receiving surface of the power supply photovoltaic panel 4 is cleaned by the cleaning piece 5.
Specifically, a photovoltaic cell panel cleaning device comprises a cleaning robot 1, a robot moving platform 2, a platform moving track 3, a power supply photovoltaic panel 4 and cleaning pieces 5.
In the prior art, a power station is generally provided with a plurality of rows of power generation photovoltaic panels, and due to the limitations of a photovoltaic panel mounting platform and a self-walking device structure of the cleaning robot 1, the cleaning robot 1 cannot realize steering, row-changing cleaning, and one row of photovoltaic panels is intelligently cleaned at a time. Therefore, the cleaning robot 1 needs to perform a replacement operation with the robot moving platform 2 and the platform moving rail 3.
In this embodiment, the power supply photovoltaic panel 4 is mounted on the platform moving rail 3, and the cleaning member 5 is mounted on the bottom of the robot moving platform 2. When the robot moving platform 2 drives the cleaning robot 1 to change the row, the robot moving platform 2 can drive the cleaning piece 5 to clean the cleaning piece through the power supply photovoltaic panel 4 arranged on the platform moving track 3. Because the cleaning robot 1 is required to change the row frequently, the row-changing cleaning piece 5 can clean the power supply photovoltaic panel 4 once every time, the power generation efficiency of the cleaned power supply photovoltaic panel 4 is increased, and the normal power supply of the cleaning robot 1 is ensured. The cleaning piece 5 is a detachable rolling brush which is rotationally connected to the robot moving platform 2, and the rolling brush is rotationally cleaned in a different flat scraping cleaning mode: the photovoltaic module can be cleaned efficiently and the risk of damaging the surface of the power supply photovoltaic panel 4 is reduced.
Since the power supply photovoltaic panel 4 in the embodiment is mounted on the platform moving track 3, a supporting platform for mounting the power supply photovoltaic panel 4 does not need to be additionally built in a power station, and the power supply photovoltaic panel is particularly suitable for outdoor space and high-altitude scenes in which the supporting platform is difficult to build. And the power supply photovoltaic panel 4 is arranged on the platform moving track 3 and is positioned on the walking path of the robot moving platform 2, and the cleaning of the power supply photovoltaic panel 4 can be finished only by arranging one cleaning piece 5, so that an additional driving device is not needed, and the structure is simple and the installation is easy. Further, since the cleaning robot 1 is also mounted on the robot moving platform 2, the cleaning robot 1 passes through the power supply photovoltaic panel 4, and the distance between the two is short, thereby facilitating charging.

In addition, to ensure the conduction of the charging circuit and the charging efficiency, more than two conductive sliding grooves 611 are included, and the number of the conductive sliding blocks 612 is adapted to the number of the conductive sliding grooves 611. To prevent leakage, the outside of the conductive runner 611 is covered with an insulating material, and the housing of the cleaning robot 1 is made of an insulating material.
