Description

Technical Field

[0001] This invention relates to equipment for cleaning and spraying, and particularly to equipment for cleaning and spraying photovoltaic panels, specifically, an integrated robot for automatic cleaning and brushing of photovoltaic panels. Background Technology

[0002] With the continuous rise in global energy demand and the increasing prominence of environmental protection issues, the surge in global photovoltaic installations and the growing demand for efficient and clean technologies have led to automatic cleaning systems gradually becoming an important technical means in the maintenance of modern photovoltaic power plants.

[0003] Traditional methods for cleaning photovoltaic panels, such as manual cleaning including manual brushing and vehicle water spraying, are simple to operate and low in cost, but they are time-consuming and labor-intensive, difficult to cover large-area photovoltaic power stations, and may damage the surface of the photovoltaic panels.

[0004] In particular, in northern winters, the outdoor ambient temperature is low and there is a lot of snowfall. The surface of the photovoltaic panels will freeze at low temperatures, and the meltwater at the interface between the photovoltaic panels and the snow will also freeze, making it difficult to clean the photovoltaic panels.

[0005] Therefore, it is necessary to provide an integrated robot for automatic cleaning of photovoltaic panels and a roller brush to solve the above problems. Summary of the Invention

[0006] The purpose of this invention is to provide an integrated robot for automatic cleaning of photovoltaic panels and a roller brush. The robot cleans the surface of the photovoltaic panels, reducing stain adhesion and extending the cleaning cycle. At the same time, based on automatic cleaning, a roller brush coating mechanism is integrated to coat the surface of the photovoltaic panels with an anti-icing coating. The anti-icing coating prevents the photovoltaic panels from freezing in low-temperature environments and prevents meltwater from freezing at the interface between the photovoltaic panels and snow accumulation, thereby achieving the purpose of rapid cleaning.

[0007] The technical solution is as follows:

[0008] A photovoltaic panel automatic cleaning and roller brush integrated robot includes a wheeled chassis trolley, with two rollers at each end of the wheeled chassis trolley, and a rotating shaft connected to the rollers at both ends. A pulley A is provided at one end of the rotating shaft.

[0009] The upper part of the wheeled chassis trolley is connected to a steel structure frame, and the steel structure frame is divided into two areas to house the cleaning device and the coating device, respectively.

[0010] The cleaning device includes a spray nozzle, a brush, and a water-drying device;

[0011] The coating device includes a coating solution storage tank, a peristaltic pump and a liquid metering controller. The liquid outlet pipe is placed inside the roller brush and is equipped with liquid outlet micropores. A liquid return pipe is provided at the end of the liquid outlet pipe, through which excess liquid is returned to the storage tank.

[0012] Furthermore, the wheeled chassis trolley is driven by a servo motor A, which is equipped with a pulley B. The pulley A and pulley B are connected by a belt A, which is equipped with a tensioner A.

[0013] Furthermore, guide wheels and limit sensors are respectively installed on both sides of the wheeled chassis trolley.

[0014] Furthermore, the nozzle is equipped with a cleaning fluid storage tank, a liquid inlet, a liquid metering controller, a liquid inlet control valve, and a liquid outlet manifold.

[0015] Furthermore, a pulley C is provided at one end of the brush. The brush is driven by a servo motor B, which drives the pulley D and connects it with the pulley C and pulley E via a belt B. The belt is equipped with a tensioner B.

[0016] Furthermore, the water stain drying device includes a scraper-type water removal device and a belt-type cloth water removal device.

[0017] Furthermore, the scraper-type water removal device includes a rubber scraper blade and a scraper blade mounting plate.

[0018] Furthermore, the belt-type rag dewatering device includes a pulley E, which is connected to the rag roller A and rag roller B via a belt-type absorbent rag, and is also equipped with a rag wringing roller.

[0019] Furthermore, the coating device uses a roller brush for coating.

[0020] Compared to existing cleaning technologies, this invention uses robots to clean the surface of photovoltaic panels, reducing stain adhesion and extending the cleaning cycle. Simultaneously, based on automated cleaning, a roller brush coating mechanism is integrated to coat the photovoltaic panel surface with an anti-icing coating, preventing the photovoltaic panels from freezing in low-temperature environments, such as after heavy snowfall, preventing meltwater from freezing at the interface between the photovoltaic panel and snow accumulation, thus achieving rapid cleaning.
