Surface cleaning robot for solar photovoltaic array and control method thereof

Abstract

The invention discloses a surface cleaning robot for a solar photovoltaic array and a control method thereof. The robot mainly comprises a photovoltaic panel cleaning device and a control device; the cleaning device cleans inclined solar photovoltaic panels and comprises self-cleaning films, one-way damping slide rails and a cleaning slide rod, the self-cleaning films are arranged on the surfaces of the solar photovoltaic panels, the one-way damping slide rails are arranged on the two sides of the surfaces of the solar photovoltaic panels, and the cleaning slide rod is arranged on the one-way damping slide rails in an erected mode and is provided with power through connection between a spring hose and a high-pressure air pump; the control device comprises a timing switch, and the timing switch is connected to the high-pressure air pump. According to the surface cleaning robot for the solar photovoltaic array and the control method thereof, the high-pressure air pump provides the power, thereby saving the energy, protecting the environment and meeting the geographical conditions of the west area. The single timing switch is used for completing integrated control over a main circuit, and different cleaning time can be set according to different seasons; by adopting the high-pressure air pump and the one-way damping slide rails, a motor is eliminated completely, and therefore the installation cost and the maintenance cost are greatly lowered.

Description

【Technical field】 [0001] The patent of the invention relates to the fields of electrical engineering and its automation, nano and new energy applications, and in particular to a solar photovoltaic array surface cleaning robot and its control method. 【Background technique】 [0002] With the construction of new countryside and the depletion of non-renewable energy sources such as coal and oil, people pay more and more attention to the development and utilization of new energy sources. my country is rich in photovoltaic resources, and the west has the largest solar energy resources in my country. Long-term sunlight and vast land are huge potentials for solar energy development. 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.

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.
