Description

Technical Field

[0001] This utility model relates to the field of photovoltaic cleaning robots, and in particular to a photovoltaic cleaning robot with a roller brush assembly. Background Technology

[0002] A photovoltaic (PV) panel is a power generation device that generates direct current when exposed to sunlight. It consists of thin, solid photovoltaic cells made almost entirely of semiconductor materials (such as silicon). Because PV panels are exposed to the outdoor environment for a long time, dust and impurities easily accumulate on their surface. Dust and impurities can block sunlight and affect the performance of PV panels. Due to the large area of ​​PV panels, cleaning robots are usually used for cleaning.

[0003] Most improvements to photovoltaic robots in existing technologies focus on cleaning and installation methods. For example, Chinese patent document CN219068152U discloses a roller brush assembly based on a photovoltaic cleaning robot, comprising: a bracket for supporting the roller brush; the bracket includes a crossbeam, a support arm, and a power compartment; a support shaft is provided at the front end of the support arm, and the support shaft is connected to one end of the roller brush; a motor and a gearbox are provided in the power compartment; the output shaft of the motor is connected to the input end of the gearbox; the output shaft of the gearbox passes through a hole in the power compartment and connects to the other end of the roller brush; the output shaft of the gearbox is coaxial with the support shaft. The roller brush assembly based on a photovoltaic cleaning robot described in this invention can quickly clean the coverings on the surface of photovoltaic panels, improving the power generation efficiency of the photovoltaic panels. The roller brush assembly is easy to disassemble and detach from the main unit, facilitating site changes and transportation.

[0004] While the aforementioned devices offer certain advantages in terms of cleaning and installation methods, they still have shortcomings:
