Description

Photovoltaic cleaning device

Technical Field

The invention belongs to the technical field of photovoltaic cleaning, and in particular relates to a photovoltaic cleaning device.

Background technique

Photovoltaics can be divided into multiple types according to the rules of geographical distribution, including urban photovoltaics, offshore photovoltaics, mountain photovoltaics, etc. Among them, mountain photovoltaics refers to photovoltaic power stations built under complex terrain conditions such as mountains and hills. For example, some areas in my country with more hilly areas are suitable for the implementation of mountain photovoltaics.

Although mountain photovoltaics can provide a large amount of green electricity, in actual use, due to the steep terrain of this type of area, vehicles and power equipment are difficult to reach. During the later operation and maintenance, the cleaning of photovoltaic panels is mainly done by manpower. More specifically, considering the cost issue, local people are mainly hired. After simple training, they use long-pole brushes and flushing water to clean the panels.

However, due to the steep terrain, lack of water resources, and the fact that the inclination angle of photovoltaic panels is often greater than 45 degrees, when people use long-pole brushes, their arms are kept lifted for a long time, which can easily cause soreness due to insufficient blood supply. They need to rest frequently, resulting in reduced work efficiency. When they pull the long-pole brush backwards, the overall center of gravity moves backwards, and on steep slopes, it is easy to lose their footing and fall backwards, posing certain safety hazards.

The spring 25 is compressed, and after the disc 26 moves up beyond the water inlet 24, the water in the water inlet pipe 23 is pushed into the L-shaped tube 18 by the principle of negative pressure, and finally sprayed out from the corresponding atomizing nozzle 10. On the contrary, when the inner tube 11 and the L-shaped tube 18 approach each other, the disc 26 moves downward to the initial position under the elastic force of the spring 25, so that the water in the water tank 16 can be replenished into the water inlet pipe 23.

The working principle and beneficial effects of the above technical solution are as follows: when the electric disc brush 5 moves, it will drive the anti-detachment hook 7 to move synchronously. When the electric disc brush 5 moves downward, it will drive the anti-detachment hook 7 to synchronously hook the upper side of the photovoltaic panel. The staff can move the device horizontally to adjust the cleaning area during this process. The anti-detachment hook 7 can prevent the device from being separated from the photovoltaic panel due to center change or improper operation during the movement, thereby improving the stability of the device.

In one embodiment: a perovskite photovoltaic panel 9 is installed on the upper surface of the electric disc brush 5, and nano-phosphors for improving the anti-ultraviolet corrosion capability of the perovskite photovoltaic panel 9 are integrated inside.

The working principle and beneficial effects of the above technical solution are as follows: the perovskite material itself is modified by integrating nano-phosphors on the surface of the perovskite photovoltaic panel 9, and the property of the nano-phosphors that can down-convert high-energy ultraviolet photons into low-energy visible light photons is utilized, and the optical and electronic properties such as high absorption coefficient, high carrier mobility, long carrier recombination lifetime and unique defect physics of the perovskite material itself are combined, so that the perovskite solar cell with nano-phosphors integrated inside has the characteristics of increased power conversion rate, extended outdoor working service life and long-term storage of photon energy compared to the perovskite solar cell without nano-phosphors integrated in the past.

Working principle and usage process:

First, place the device on the surface of the photovoltaic panel to be cleaned, and adjust the position so that the two guide wheels 6 are against the upper edge of the photovoltaic panel to be cleaned, and the guide plate 1 is against the upper surface of the lower edge of the photovoltaic panel. Then start the servo motor 17, and the output shaft of the servo motor 17 rotates, driving the bidirectional screw rod 19 to rotate synchronously, so that the electric disc brush 5 and the slider 12 move away from or close to each other, and the surface of the photovoltaic panel in the rectangular area is cleaned.

At the same time, the electric disc brush 5 drives the inner tube 11 and the L-shaped tube 18 to slide relative to each other. When the inner tube 11 and the L-shaped tube 18 move away from each other, the traction rope 22 on the cross bar 21 is pulled, and the other end of the traction rope 22 pulls the disc 26 to move up relative to the water inlet pipe 23. The spring 25 is compressed. After the disc 26 moves up and exceeds the water inlet 24, the water in the water inlet pipe 23 is pushed into the L-shaped tube 18 by the negative pressure principle, and finally sprayed out from the corresponding atomizing nozzle 10. On the contrary, when the inner tube 11 and the L-shaped tube 18 are close to each other, the disc 26 moves downward to the initial position under the elastic force of the spring 25, so that the water in the water tank 16 can be supplemented into the water supply component in the water inlet pipe 23 to transport water to the area, and cooperate with the cleaning component for cleaning. Since the photovoltaic panel is arranged at an angle, the sewage after cleaning is blocked and will not flow around. It will only flow out from the outlet trough 27, filter through the filter screen 20 and return to the water tank 16 for secondary recycling.

When the electric disc brush 5 moves, it will drive the anti-detachment hook 7 to move synchronously. When the electric disc brush 5 moves downward, it will drive the anti-detachment hook 7 to synchronously hook the upper side of the photovoltaic panel. The staff can move the device horizontally to adjust the cleaning area during this process. The anti-detachment hook 7 can prevent the device from being separated from the photovoltaic panel due to center change or improper operation during the movement, thereby improving the stability of the device. The setting of the handle 14 makes it convenient for the staff to move the device horizontally. The anti-scratch pad 13 can prevent the photovoltaic panel from being scratched during the movement of the device.
