Description

Technical Field

[0001] This utility model relates to the field of photovoltaic panel cleaning, and in particular to a cleaning device. Background Technology

[0002] The core of a photovoltaic (PV) panel is a solar cell made of semiconductor materials (such as silicon). When sunlight shines on it, photons interact with electrons in the semiconductor, exciting them to break free from atomic bonds and form free electrons, while leaving holes. This process is called the photoelectric effect. Solar cells achieve energy conversion through the following steps: photon energy is absorbed by the semiconductor; if the energy exceeds the material's bandgap, electrons are excited; in the pn junction structure, electrons are pulled towards the n-region, and holes are pushed towards the p-region, creating a potential difference; an external circuit connects the n-region and p-region electrodes, and the flow of electrons forms a current, completing the conversion of light energy into electrical energy.

[0003] Photovoltaic panels generate electricity by absorbing photons from sunlight, and their power generation efficiency directly depends on the amount of light absorbed. However, over long-term use, dust, bird droppings, leaves, pollen, and other contaminants easily accumulate on the surface of photovoltaic panels. These contaminants can block sunlight, reduce the area of ​​the solar panels that receives light, thereby decreasing the photoelectric conversion efficiency and potentially damaging the photovoltaic panels themselves. Therefore, photovoltaic panels need to be cleaned regularly. In the authorized Chinese utility model patent "Announcement No.: CN217700236U, Title: A Photovoltaic Panel Cleaning Device", a first drive motor drives a first lead screw, and a second drive motor drives a second lead screw. Since one end of the first horizontal plate is sleeved on a first threaded groove and the other end of the first horizontal plate is sleeved on a second threaded groove, the first horizontal plate can move vertically up or down. The first support plate and the second support plate are fixedly connected to the first horizontal plate through a first reference end, so the first support plate and the second support plate can move vertically up or down, thus adapting to photovoltaic panels of different heights. However, the above application requires overall adjustment of the height of the cleaning device, which requires more energy to maintain the weight of the cleaning device, thus increasing the production and use costs of the cleaning device.
