Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cleaning devices, in particular to a multi-point driving photovoltaic cleaning robot. BACKGROUND

[0002] The photovoltaic panel is an assembly of a plurality of solar cell assemblies assembled on a panel in a certain way, and is a device for converting solar radiation energy into electric energy through photoelectric effect or photochemical effect directly or indirectly. When the photovoltaic panel is covered with dust, the light intensity reaching the surface of the photovoltaic cell is weakened, the photovoltaic power generation is reduced, and hot spot effect occurs. Therefore, the power station operation and maintenance urgently needs efficient, stable and reliable cleaning equipment to clean the photovoltaic panel. However, it is found that the existing photovoltaic cleaning robot has the following defects: the cleaning robot system with upper and lower tracks runs relatively stably, but the installation of upper and lower tracks requires a larger installation space, and when the installation space is small, two sets of photovoltaic cleaning robots cannot be installed at the same time.

[0003] The installation of the track of the traditional track type automatic cleaning system needs a larger space reserved in the photovoltaic power station, and if two sets of equipment are installed at the same time, a larger installation space is needed. Many photovoltaic power stations do not have enough installation space. The present application is suitable for a photovoltaic power station with a small space reserved between arrays in advance. The newly designed photovoltaic cleaning robot shares a middle track, which reduces the cost. SUMMARY

[0004] In view of this, in order to solve the technical problem that the gap reserved at the position of the existing distributed photovoltaic power station is too small when the components are laid, and the space is not enough to install the tracks of two sets of photovoltaic panel cleaning robots, the present application provides a multi-point driving photovoltaic cleaning robot.
