[0041] The following examples are described below Figures 1 to 7 .

[0042] The embodiment of the application provides a kind of photovoltaic panel cleaning device, comprising:

[0043] Mounting bracket 1, the wide slot for installing photovoltaic panel 10 is arranged in middle part, and first sliding groove 11 is arranged on the top surface of opposite edge of wide slot four sides;

[0044] Moving mechanism, it includes motor 47, first positioning plate 2, second positioning plate 3, first transmission assembly, second transmission assembly, rotating shaft 45 and gyro wheel 46;The first positioning plate 2 and second positioning plate 3 are arranged in parallel;The inner side surface on the first positioning plate 2 is installed with motor 47, and the outer side surface on the first positioning plate 2 is installed with first drive assembly, and the output shaft of motor 47 is connected with the first transmission assembly;Second transmission assembly is installed on the outer side of second positioning plate 3;Two rotating shafts 45 are respectively connected with the first transmission assembly and second transmission assembly, and gyro wheel 46 that is adapted to the first sliding groove 11 is fixedly sleeved on both sides of rotating shaft 45;

[0045] Cleaning mechanism, it includes cleaning roller 51 movably connected between the first positioning plate 2 and the second positioning plate 3, and water spraying assembly is arranged on the first positioning plate 2 and the second positioning plate 3.

[0046] In the embodiment, the wide slot for installing photovoltaic panel 10 is arranged in the middle part of mounting bracket 1, and the wide slot provides accurate positioning and stable support for photovoltaic panel 10.

[0047] Motor 47 of moving mechanism is used as power source, rotating shaft 45 and gyro wheel 46 are driven to rotate by first transmission assembly and second transmission assembly.Gyro wheel 46 is adapted to the first sliding groove 11 on the top surface of opposite edge of wide slot of mounting bracket 1, so that the cleaning device can move stably along the sliding groove, and different positions of photovoltaic panel 10 are cleaned.Whether in large-area photovoltaic panel 10 array or in complex photovoltaic panel 10 layout, the cleaning device can move freely according to needs, effectively covers each area of photovoltaic panel 10, and improves the comprehensiveness of cleaning.

[0048] The cleaning roller 51 in the cleaning mechanism is movably connected between the first positioning plate 2 and the second positioning plate 3, so that the cleaning roller 51 can be in contact with and roll on the surface of the photovoltaic panel 10 under the driving of the moving mechanism. During the rolling, the cleaning roller 51 can effectively remove the dust, dirt and other pollutants on the surface of the photovoltaic panel 10, thereby improving the absorption and conversion efficiency of the photovoltaic panel 10 to sunlight. It should be noted that the surface of the cleaning roller 46 is wrapped with soft rubber or sponge. The soft rubber is suitable for cleaning the conventional photovoltaic panel 10, especially for the photovoltaic panel 10 which is sensitive to the surface and easy to be scratched. The soft rubber cleaning roller 46 can effectively remove the dust and light dirt while minimizing the damage to the photovoltaic panel 10.

[0049] The water spraying assembly arranged on the first positioning plate 2 and the second positioning plate 3 further enhances the cleaning effect. While the cleaning roller 51 is working, the water spraying assembly can spray water to the surface of the photovoltaic panel 10, so that the stubborn dirt can be more easily removed by the cleaning roller 51 after being wetted by water. The water spraying assembly can reasonably control the water spraying amount and range according to the actual cleaning requirement, so as to ensure that the cleaning process is efficient and water-saving. For some pollutants with strong viscosity, such as bird droppings and tree gum, better cleaning effect can be achieved and the service life of the photovoltaic panel 10 can be prolonged by wiping after wetting.

[0050] The photovoltaic panel cleaning device of the utility model cooperates with the mounting frame 1, the moving mechanism and the cleaning mechanism, is convenient for installation and use in different photovoltaic power station environments, drives the cleaning mechanism on the surface of the photovoltaic panel 10 through the moving mechanism, and can efficiently clean the photovoltaic panel 10.

[0051] Specifically, the water spraying assembly comprises a water spraying pipe 52, a hose 54, a water storage tank 53, a fixing piece 6 and a hanging piece 7; the fixing piece 6 and the hanging piece 7 are respectively installed on the side ends of the first positioning plate 2 and the second positioning plate 3; the water storage tank 53 is installed on the top of the second positioning plate 3, the bottom of the water storage tank 53 is connected with the water spraying pipe 52 through the hose 54, and the two ends of the water spraying pipe 52 are respectively connected with the fixing piece 6 and the hanging piece 7.

[0052] In other embodiments, the fixing piece 6 and the hanging piece are installed on the two side ends of the first positioning plate 2 and the second positioning plate 3; the water spraying pipe 52 is installed on the two sides of the first positioning plate 2 and the second positioning plate 3 through the fixing piece 6 and the hanging piece 7; the bottom of the water storage tank 53 is provided with two water outlets, the two water outlets are respectively connected with the water spraying pipe 52 through the hose 54, the two ends of the water spraying pipe 52 are respectively connected with the fixing piece 6 and the hanging piece 7; a plurality of water spraying nozzles 521 are arranged on the water spraying pipe 52, and the water spraying nozzles 521 are inclined towards the photovoltaic panel 10.

[0053] It should be noted that the water tank 53 can be connected to an external pressure pump to pressurize the water. The water inlet of the pressure pump is connected to the water tank 53, and the water outlet can be connected to the water spraying pipe 52 as needed. When the pressure pump is started, it does work on the liquid, giving the liquid energy and thus increasing the pressure of the liquid. Alternatively, a small booster pump can be installed between the water tank 53 and the water spraying pipe 52. When water passes through the booster pump, the impeller of the booster pump rotates at high speed, applying centrifugal force to the water, increasing the speed and pressure of the water. The booster pump can be selected in different models and specifications according to the specific needs of the water spraying pipe 52 to meet different pressure and flow requirements. By adjusting the speed of the booster pump or setting a pressure regulating device, the water pressure in the water spraying pipe 52 can be accurately controlled.

[0054] The fixing member 6 can be installed on the side end of the first positioning plate 2 or the second positioning plate 3, and the corresponding hanging member 7 is installed on the side end of the first positioning plate 2 or the second positioning plate 3.

[0055] The water tank 53 is installed on the top of the second positioning plate 3, and two water outlets are provided at the bottom of the water tank 53. The two water outlets are connected to two hoses 54, which can simultaneously supply water to the water spraying pipes 52 installed on both sides of the first positioning plate 2 and the second positioning plate 3. The hose 54 serves as a water conveying channel and has a certain flexibility, which can adapt to the position changes caused by the movement of the cleaning device, ensuring that the water flows smoothly and unobstructed from the water tank 53 to the water spraying pipe 52.

[0056] The water spraying pipe 52 is installed on both sides of the first positioning plate 2 and the second positioning plate 3 through the fixing member 6 and the hanging member 7. The fixing member 6 and the hanging member 7 play a role in stabilizing the water spraying pipe 52, ensuring that the water spraying pipe 52 does not shake or shift during operation, thereby making the water spraying process more stable and accurate.

[0057] The water spraying pipe 52 is provided with a plurality of water spraying nozzles 521, which are inclined towards the photovoltaic panel 10. When the cleaning device starts to work, water flows from the water tank 53 to the water spraying pipe 52 through the hose 54, and then is sprayed at a certain angle to the surface of the photovoltaic panel 10 through each water spraying nozzle 521. The inclined water spraying nozzle 521 design can make the water more accurately cover a specific area of the photovoltaic panel 10, ensuring that the entire surface of the photovoltaic panel 10 can receive uniform water spraying, creating good conditions for the cleaning work of the cleaning roller 51.

[0058] Both sides are installed with water spray pipe 52 and the water spray nozzle 521 is inclined towards the photovoltaic panel 10, the water spray pipe 52 on the side of the moving forward sprays water to play the role of softening the pollutants, at this time the cleaning roller 46 cleans, and after cleaning, the water spray pipe 52 on the other side sprays water to achieve the effect of further cleaning and washing. The design of double-way water supply increases the amount of water spray, which can quickly wet the surface of the photovoltaic panel 10, and can quickly soften and dissolve some stubborn stains. Compared with single-way water spray, this design greatly improves the cleaning efficiency, shortens the cleaning time, and reduces the residence time of the cleaning device on the photovoltaic panel 10, so that more photovoltaic panels 10 can be cleaned in a shorter time.

[0059] The double-way water supply and double-sided installation can improve the cleaning effect, but users can choose single-side water spray or double-side water spray according to actual cleaning needs to meet different cleaning scenes.

[0060] Specifically, the fixing part 6 includes two movably connected fixing clamps, and the two fixing clamps are respectively provided with a semicircular notch 61; the two semicircular notches 61 form a mounting hole for sleeving one end of the water spray pipe 52.

[0061] The semicircular notch 61 is provided with a plurality of limiting grooves 62; the water spray pipe 52 is sleeved with an elastic ring 451, and the elastic ring 451 is provided with a plurality of limiting protrusions 452 matched with the limiting grooves 62.

[0062] The elastic ring 451 can be made of rubber.

[0063] The mounting hole formed by the two movably connected fixing clamps is used to mount the water spray pipe 52. At the same time, the sleeving of the mounting hole to the water spray pipe 52 and the cooperation of the limiting grooves 62 and the limiting protrusions 452 not only can provide reliable fixation for the water spray pipe 52, so that it will not easily shake or loosen during the operation of the cleaning device, ensuring the normal work of the water spray assembly, but also can adjust the position of the water spray pipe 52 and the angle of the water spray nozzle 521 by changing the limiting cooperation of different limiting grooves 62 and limiting protrusions 452, to achieve effective cleaning and meet different cleaning scenes.

[0064] Specifically, the first positioning plate 2 is further provided with a guide pulley 23; the outer side wall of the mounting frame 1 is provided with a guide sliding groove 12 matched with the guide pulley 23, and the guide pulley 23 and the guide sliding groove 12 form a sliding connection.

[0065] The guide pulley 23 is installed on the first positioning plate 2, and the guide sliding groove 12 is arranged on the outer side wall of the mounting frame 1, and the two are matched with each other. When the cleaning device moves, the guide pulley 23 rolls in the guide sliding groove 12, and since the sliding groove limits the movement track of the pulley, the entire cleaning device is guided to move in a preset direction, ensuring that the movement direction of the cleaning device is accurate and stable.

[0066] Specifically, the first transmission assembly includes a first belt pulley 41, two second belt pulleys 42, and a first belt 43; the output shaft of the motor 47 is connected to the first belt pulley 41 through the first positioning plate 2; the two second belt pulleys 42 are respectively sleeved on one end of the rotating shaft 45; and the first belt pulley 41 and the two second belt pulleys 42 are in transmission connection through the first belt 43.

The two second belt pulleys 42 are respectively sleeved on one end of the rotating shaft 45, and the first belt pulley 41 and the two second belt pulleys 42 are in transmission connection through the first belt 43. In this way, the rotation of the first belt pulley 41 is transmitted to the two second belt pulleys 42 through the first belt 43, thereby driving the rotating shaft 45 to rotate, achieving power transmission, and enabling the roller 46 connected to the rotating shaft 45 to rotate, thereby driving the cleaning device to move.

[0068] Specifically, the first transmission assembly further includes two tension pulleys 44; the two tension pulleys 44 are respectively installed on the first belt pulley 41 and the two second belt pulleys 42 to form a triangular waist position, and the tension pulleys 44 are movably connected to the first positioning plate 2; and the belt is sequentially sleeved on the first belt pulley 41, the first tension pulley 44, the first second belt pulley 42, the second second belt pulley 42, and the second tension pulley 44 in a clockwise direction.
