Solar photovoltaic array surface cleaning robot and control method thereof

Abstract

The invention discloses a solar photovoltaic array surface cleaning robot and a control method thereof. The robot is mainly composed of a photovoltaic panel cleaning device and a control device; the cleaning device cleans the tilted solar photovoltaic panels and includes a self-cleaning film and a one-way damping device. Slide rail and cleaning slide bar. The self-cleaning film is set on the surface of the solar photovoltaic panel. The one-way damping slide rail is set on both sides of the surface of the solar photovoltaic panel. The cleaning slide bar is set up on the one-way damping slide rail. The cleaning slide bar is softly connected by a spring. The pipe is connected to a high-pressure air pump to provide power; the control device includes a timing switch, and the timing switch is connected to the high-pressure air pump. The invention uses a high-pressure air pump to provide power, is energy-saving, environmentally friendly and conforms to the geographical environment of the western region. A single timer switch is used to complete the integrated control of the main circuit, and different cleaning durations can be set according to different seasons; the use of high-pressure air pumps and one-way damping slide rails completely eliminates the need for motors, greatly reducing installation and maintenance costs.

Description

Problems solved by technology

However, most of the large-scale solar energy bases in my country are located in the northwest region. The climate in the northwest region is dry, less rainy, and the annual sunshine is long. At the same time, this type of region is also the region with the most scarce power resources in China. There are no large rivers, and low-cost clean energy power generation cannot be carried out. Excessive reliance on thermal power generation creates a huge demand for coal resources

Coal production in such areas is not high, and they rely too much on long-distance transportation, which greatly increases the cost

The west is also an important area for the promotion and application of solar photovoltaic development. Solar photovoltaics mainly use photovoltaic arrays. However, the west is characterized by windy, sandy, and little rainfall, which can easily cause pollution to photovoltaic arrays. For example, dust is easy to deposit on the surface of solar energy. It also increases the workload of cleaning and maintenance, but at present, the efficiency of manual cleaning is low and the cleaning cost is high, which has affected the promotion of solar energy.
