Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic arrays, and in particular to a photovoltaic array dust cleaning device based on an unmanned aerial vehicle. Background Art

[0002] A photovoltaic array is a collection of multiple photovoltaic modules, also known as solar panels, connected in series and / or parallel. It converts solar radiation directly into electricity. PV arrays are the core component of photovoltaic power generation systems, ranging in size from small household systems to large solar power plants. Traditional PV panel cleaning methods typically rely on manual labor, using water rinsing or brushes. This is costly in large-scale PV power plants, especially in remote areas or at high altitudes, where cleaning becomes even more difficult. Therefore, drone-based PV array cleaning devices are needed.

[0003] At present, existing cleaning devices usually use high-pressure water guns or water spray systems to clean photovoltaic arrays. In order to achieve the ideal cleaning effect, it is often necessary to increase the water pressure or increase the duration of the water spray, which directly leads to more water consumption. Therefore, this application provides a photovoltaic array cleaning device based on a drone to meet the needs. Utility Model Content

[0011] Preferably, one end of the second delivery pipe is connected to the water outlet end of the water tank, and the other end is connected to the water suction end of the water pump.

[0012] Preferably, the control box is arranged on the bracket.

[0013] Compared with the prior art, the present invention has at least the following beneficial effects:

DETAILED DESCRIPTION

[0022] The following describes in detail a drone-based photovoltaic array cleaning device provided by the present invention, with reference to the accompanying drawings and specific embodiments. It is also noted that, for the sake of completeness, the following embodiments are best and preferred embodiments. For some known technologies, those skilled in the art may employ alternative implementations. Furthermore, the accompanying drawings are provided solely for the purpose of describing the embodiments in greater detail and are not intended to limit the present invention.

[0023] like Figure 1 - Figure 4 As shown, an embodiment of the present invention provides a photovoltaic array cleaning device based on a drone, including: a bracket 1; a placement plate 3, arranged on the bracket 1; a driving assembly 4, arranged on the placement plate 3; a conveying assembly 5, arranged on the placement plate 3; two fixed plates 6, arranged on the placement plate 3, and located at the edge of the placement plate 3 and distributed front and back; a movable plate 7, rotatably arranged on the outside of the fixed plate 6; a first nozzle 11, arranged on the movable plate 7, for spraying a more concentrated water column; a second nozzle 12, arranged on the movable plate 7, for spraying a fine water mist; a first connecting pipe 8, one end of which is connected to the conveying assembly 5; a diverter valve 10, arranged at the other end of the first connecting pipe 8; two second connecting pipes 9, one end of which is respectively connected to the diverter valve 10, and the other end of which is respectively connected to the first nozzle 11 and the second nozzle 12.

[0024] By setting up a second nozzle 12 for spraying fine water mist, the surface of the photovoltaic array can be evenly covered, and dust and dirt can be moistened and initially gathered. Because the water mist can increase the adhesion between dust, it is convenient for subsequent centralized cleaning, so that less water is used in the overall cleaning process; by setting up a first nozzle 11 for spraying fine water mist, after the water mist pre-cleaning, the first nozzle 11 deeply cleans the surface of the photovoltaic array by spraying a more concentrated water column, ensuring that the surface of the photovoltaic panel is thoroughly cleaned and reducing water waste; by setting up a diverter valve 10, the water flow can be switched between the second nozzle 12 and the first nozzle 11 to realize the alternating use of water mist and water column.

[0025] Drive assembly 4 includes a motor 41 mounted on plate 3 and a rotating rod 42 mounted at the output end of motor 41. With motor 41 secured to the output end and rotating rod 42, when an external current is applied to motor 41, the output end generates rotational force, which drives rotating rod 42 to generate synchronous motion, providing a source of power for its rotation.

[0026] Both sides of the rotating rod 42 penetrate the fixed plate 6 and are connected to the movable plate 7. By providing the rotating rod 42, the rotating rod 42 transmits the power of the motor 41 to the movable plate 7, thereby realizing the rotation of the movable plate 7.

[0027] The conveying assembly 5 includes: a water tank 51 , which is arranged on the placement plate 3 and is used to store water; a U-shaped tube 54 , which is arranged on the placement plate 3 , and one end of the first connecting tube 8 is connected to the U-shaped tube 54 .

[0028] By setting up a water tank 51, its main function is to store cleaning water to ensure sufficient water supply during the cleaning process. A water inlet is set at the top of the water tank 51, and a drain outlet is set at the bottom of the water tank 51. A valve is set on the drain outlet, and the drain outlet is connected to the second delivery pipe 52; by setting up a first connecting pipe 8, it is responsible for transmitting water from the delivery component 5 to the nozzle. By adopting a telescopic hose, the first connecting pipe 8 can adapt to the rotation of the movable plate 7 to ensure stable transmission of the water flow.

[0029] A water pump 55 is mounted on the mounting plate 3. A first delivery pipe 53 is connected to the water delivery end of the water pump 55 and to the U-shaped pipe 54 at its other end. The water pump 55 is responsible for pressurizing the water in the water tank 51 and delivering it to the nozzles. This ensures that the water reaches the nozzles with sufficient pressure, providing a power source for cleaning and ensuring that the cleaning medium is sprayed with sufficient force onto the surface of the photovoltaic array.

[0030] One end of the second delivery pipe 52 is connected to the water outlet of the water tank 51, and the other end is connected to the water intake of the water pump 55. By providing the second delivery pipe 52, the water in the water tank 51 can be delivered to the water pump 55, providing a stable water supply to the water pump 55, so that the water pump 55 can continuously provide the water pressure required for cleaning, ensuring the normal operation of the first nozzle 11 and the second nozzle 12.

[0031] The control box 2 is set on the bracket 1. By setting up the control box 2, it is responsible for coordinating and controlling the work of all components. Through the intelligent control of the control box 2, the automation of the cleaning process is realized, the manpower requirement is reduced, and the accuracy and consistency of cleaning are improved.

[0032] The technical solution provided by the present invention is that when in use, the bracket 1 is installed on the drone, and the water pump 55 and the diverter valve 10 are turned on and operated through the control box 2. The water pump 55 draws out the water in the water tank 51 through the second delivery pipe 52, and delivers the water to the first connecting pipe 8 through the first delivery pipe 53 and the U-shaped pipe 54. First, the water is delivered to the second nozzle 12 through the diverter valve 10, and water mist is sprayed on the surface of the photovoltaic array through the second nozzle 12. The water mist falls on the surface of the photovoltaic array and first gathers the surface dust together. Then, the water is delivered to the first nozzle 11 through the diverter valve 10, and a water column is sprayed through the first nozzle 11 to clean the surface of the photovoltaic array. When the nozzle angle needs to be adjusted, the motor 41 is turned on and operated by the control box 2, which drives the rotating rod 42 to rotate, so that the movable plate 7 rotates, thereby adjusting the nozzle to vertically downward or inclined, so that the sprayed water mist or water column is sprayed vertically downward or inclined.

[0033] This invention encompasses any alternatives, modifications, equivalents, and solutions that do not depart from the spirit and scope of this invention. While specific details are described in detail in the preferred embodiments of this invention to provide a thorough understanding, those skilled in the art will be able to fully understand this invention without these details. Furthermore, to avoid unnecessary confusion regarding the essence of this invention, well-known methods, processes, procedures, components, and circuits have not been described in detail.

[0034] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
