Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic power generation, in particular to a ferry device of a photovoltaic cleaning robot. Background Art

[0002] Photovoltaic power generation is a technology that uses the photovoltaic effect of semiconductor interfaces to directly convert light energy into electrical energy. At present, photovoltaic modules are generally used to receive sunlight. Since photovoltaic modules are installed outdoors, dust often accumulates on the surface of photovoltaic modules. Existing technology generally uses photovoltaic cleaning robots to replace manual cleaning work. Since there are multiple rows of photovoltaic modules, a ferry device is required to move the photovoltaic cleaning robot from one row to another.

[0003] The prior art can refer to the Chinese patent with authorization announcement number CN216915868U, which discloses a cleaning shuttle bus and a photovoltaic cleaning device, including a body frame, a walking wheel assembly and a limiting wheel assembly. The body frame is used to fix the cleaning robot. The walking wheel assembly and the limiting wheel assembly are both arranged on the body frame. The walking wheel assembly can roll along two guide rails arranged at intervals along the width direction of the body frame. The front and rear ends of the body frame are provided with limiting wheel assemblies, and the limiting wheel assemblies can abut against the inner walls of the corresponding side guide rails, thereby realizing the limiting and deviation correction of the walking wheel assembly.

[0004] However, the length of the vehicle body frame in the above-mentioned cleaning shuttle is fixed, and the length of the existing photovoltaic modules will be adjusted according to site requirements. Therefore, the length of the photovoltaic cleaning robot will be adjusted according to the length of the photovoltaic modules, which may cause the photovoltaic robot to be incompatible with the cleaning shuttle, thereby reducing the applicability of the ferry device.
