Description

Technical Field

[0001] The utility model relates to the technical field of cleaning of photovoltaic power stations, in particular to an automatic cleaning device for distributed photovoltaic power stations. Background Art

[0002] With the general improvement of existing living conditions, photovoltaic power stations are becoming more and more common in our daily lives. Compared with traditional fossil energy power generation, photovoltaic power generation does not produce substances that are harmful to the environment, and the way of generating energy is more direct and cleaner. Therefore, it has attracted people's attention. Most of the existing photovoltaic power stations are concentrated in the wild. Due to the presence of dust in the air for a long time, dust is easily accumulated on the power generation panels, which in turn blocks sunlight, resulting in reduced power generation efficiency. However, there are few existing devices for cleaning power generation panels, and most of them require manpower to complete, which not only reduces the cleaning efficiency, but also requires a lot of manpower costs, thereby increasing maintenance costs. In addition, the existing water spray cleaning equipment will leave water stains on the photovoltaic panels, which are still more susceptible to dust during the drying process. Utility Model Content

[0024] It should be noted that all directional indications in the embodiments of the present application are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0025] In this application, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.
