Background technique

A photovoltaic panel module is a power generation device that generates direct current when exposed to sunlight. It is composed of thin solid photovoltaic cells that are almost entirely made of semiconductor materials (such as silicon).

When photovoltaic panels are used outdoors for a long time, a certain amount of dust will accumulate on the surface of the photovoltaic panels, which will affect the power generation effect of the photovoltaic panels, so the photovoltaic panels need to be cleaned.

Most of today's photovoltaic panel cleaning uses fixed photovoltaic cleaning machines, fiber brush photovoltaic cleaners and remote-controlled photovoltaic panel cleaning robots. However, the cost of fixed photovoltaic cleaning machines is high. Tracks need to be laid in advance when installing photovoltaic panels, and the structure Complex use conditions are harsh, and only large and continuous photovoltaic panels can be used. Dispersed photovoltaics or photovoltaics with different sizes cannot be cleaned well and are not suitable for home use. Fiber brush photovoltaic cleaners require external water pipes. It needs to rely entirely on manual scrubbing. If the photovoltaic panels in remote locations are not properly cleaned, the safety of roof operations is not guaranteed. The remote-controlled photovoltaic panel cleaning robot requires an external water pipe and requires a person to use a remote control to control the size of the photovoltaic panel that cannot climb the slope greater than 25 degrees. Too large for home use.

Therefore, it is necessary to provide a household photovoltaic panel cleaning robot to solve the above technical problems.

The working principle of a household photovoltaic panel cleaning robot provided by the utility model is as follows.

The rectangular cleaning robot uses a quick-release method to fix the fiber rag 10 (Velcro, etc.) at the bottom. It cleans the photovoltaic panels by squeezing and vibrating the casing 1, eliminating the trouble of manual cleaning. It has edges around it to prevent falling. Sensor 4, the first cleaning can be used for cleaning path planning and cleaning time estimation, without manual remote control intervention. After cleaning is completed, it will return to the initial placement position. The estimated remaining time allows users to know the cleaning completion time without going outdoors to check the situation; built-in When cleaning the water tank 3 (built-in cleaning fluid), the cleaning fluid is regularly sprayed onto the rag through the outlet pipe 32 through a micro water pump, eliminating the trouble of connecting to an external water source, which is very advantageous for some scenarios where it is inconvenient to connect water pipes on the roof of some homes; the built-in battery 7 can It ensures users can clean wirelessly in a short time, and the application scenarios are more diverse. At the same time, it can also be connected to the mains power. If the cleaning area is large, the city guarantees sufficient battery life; there is a visual sensor (camera) that can find the dirty locations on the photovoltaic panels for cleaning. Focus on cleaning; two fans 51 are used at the bottom to adsorb the cleaning robot to the photovoltaic panel, and the drive motor 6 drives the crawler track 61 to rotate as power; this method can avoid the problem that the photovoltaic panel installation angle is too large and the machine cannot clean; when the robot passes When two or more photovoltaic panel components are spliced into a gap, two fans 51 are used to relay the force (the suction of the fan 51 that passes first is reduced, and the suction of the fan 51 that passes later is increased to maintain stability. After the first fan 51 passes, the suction is strengthened to ensure that all Go through the gap before continuing forward.

Through the shell 1, fiber rag 10, installation groove 11, rubber scraper 2, water tank 3, water inlet 31, water outlet pipe 32, anti-fall sensor 4, air extraction frame 5, fan 51, drive motor 6, crawler track 61, battery 7 The combination of other accessories can clean photovoltaic panels cordlessly, and no external water source is needed. The power supply intelligently cleans, plans the path, and calculates the time. No manual or remote control is required. It can be adsorbed on slopes with large inclination angles to visually identify photovoltaic panels. It ensures safety and is convenient for cleaning some dispersed photovoltaic panels with different sizes, making it suitable for home use.
