Description

Technical Field

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

[0002] A photovoltaic power station is a power generation system that uses solar energy and is composed of special materials such as crystalline silicon panels, inverters and other electronic components. Its working principle is based on the photovoltaic effect, that is, when sunlight shines on photovoltaic cells, photons stimulate electrons to be released from atoms, generating electric current. This current is converted into alternating current through an inverter and then connected to the power grid for people to use. It is a green energy project encouraged by my country and aims to promote the development and utilization of renewable energy.

[0003] However, in reality, photovoltaic power stations are basically set up outdoors. When working outdoors for a long time, a large amount of dust, rain, snow, bird droppings, etc. will often accumulate on the standing photovoltaic panels. If they are not cleaned in time, they will not only corrode the photovoltaic panels and cause equipment damage; but also affect the power generation efficiency of the photovoltaic panels and reduce economic benefits.

[0027] Working principle:

[0028] Example 1

[0029] When only dust is attached to the top surface of the photovoltaic panel assembly 1, start the booster pump 6, open the solenoid valve in the first solenoid valve tube 7 and the solenoid valve in the second solenoid valve tube 8, so that the booster pump 6 pumps the desalted water inside the water tank body 41 to the interior of the transition pipe 31 through the first solenoid valve tube 7 and the second solenoid valve tube 8, and then diverts it to multiple branch pipes 32 through the transition pipe 31, and finally flushes the top surface of the photovoltaic panel assembly 1 through the multiple branch pipes 32, and the control of the electronic component structure such as the booster pump 6 can be uniformly controlled through the existing remote control system.

[0030] Example 2

[0031] When there is snow on the top surface of the photovoltaic panel assembly 1, the heating plate 42 is started, and the desalted water inside the water tank body 41 is heated by the heating plate 42. After the temperature sensor 11 detects that the desalted water is heated to a certain temperature, the booster pump 6 is started, and the solenoid valve in the first solenoid valve tube 7 and the solenoid valve in the second solenoid valve tube 8 are opened, so that the booster pump 6 pumps the desalted water inside the water tank body 41 to the interior of the transition pipe 31 through the first solenoid valve tube 7 and the second solenoid valve tube 8, and then diverts it to multiple branch pipes 32 through the transition pipe 31, and finally flushes the top surface of the photovoltaic panel assembly 1 through the multiple branch pipes 32, and at the same time, melts and cleans the accumulated snow.

[0032] Example 3

[0033] When bird droppings accumulate on the top surface of the photovoltaic panel assembly 1, the brake stepper motor 56 is started, and the brake stepper motor 56 drives the adjustment plate 54 to rotate back and forth through the transmission shaft 53, thereby causing the second discharge hole in the adjustment plate 54 to reciprocate and align with the first discharge hole in the diverter plate 52. Then, the anti-corrosion animal feces dissolving powder in the medicine box 51 flows into the interior of the water tank body 41 through the flow channel formed by the alignment of the second discharge hole and the first discharge hole.

[0034] Start the heating plate 42 and use the heating plate 42 to heat the mixed solution inside the water tank body 41. At the same time, open the solenoid valve inside the first solenoid valve tube 7, the solenoid valve inside the third solenoid valve tube 9 and the booster pump 6, so that the booster pump 6 circulates and pumps the solution inside the water tank body 41 through the first solenoid valve tube 7 and the third solenoid valve tube 9 to mix it. After the temperature sensor 11 detects that the desalted water is heated to a certain temperature, start the booster pump 6, open the solenoid valve in the first solenoid valve tube 7, the solenoid valve in the second solenoid valve tube 8 and close the solenoid valve inside the third solenoid valve tube 9, so that the booster pump 6 pumps the mixed solution inside the water tank body 41 through the first solenoid valve tube 7 and the second solenoid valve tube 8 to the interior of the transition pipe 31, and then diverts it to multiple branch pipes 32 through the transition pipe 31, and finally flushes the top surface of the photovoltaic panel assembly 1 through the multiple branch pipes 32.
