[0028] This utility model provides the following technical solution:

[0029] Example 1

[0030] Please see Figs. 1-6 This utility model provides a technical solution: a high-efficiency cleaning device for photovoltaic maintenance, including a cleaning device body 1, a storage battery installed inside the cleaning device body 1 to provide power for the operation of the device, a moving wheel 2 fixedly connected to the bottom of the cleaning device body 1, a cleaning mechanism 3 set on the top of the cleaning device body 1, a conveying mechanism 4 set on the top of the cleaning device body 1, a counterweight 6 fixedly connected to the top of the cleaning device body 1, and a handrail 5 fixedly connected to the left side of the cleaning device body 1.

A first servo motor 31 is fixedly connected to the top of the support frame 32. The output end of the first servo motor 31 passes through the support frame 32 and is fixedly connected to a threaded rod 33. A movable seat 34 is threadedly connected to the outer periphery of the threaded rod 33. The movable seat 34 is slidably connected to the inside of the support frame 32. A second servo motor 36 is fixedly connected to the left side of the movable seat 34. The output end of the second servo motor 36 passes through the movable seat 34 and is fixedly connected to a first rotating rod 37. The right side of the moving rod 37 is rotatably connected to the inner wall of the movable seat 34. A water reservoir 35 is fixedly connected to the periphery of the first rotating rod 37. A spray pipe 38 is fixedly connected to the right side of the water reservoir 35. A nozzle 394 is fixedly connected to the bottom of the water reservoir 35. Fixed plates 39 are symmetrically fixedly connected to the front and rear sides of the bottom of the water reservoir 35. A third servo motor 391 is fixedly connected to the front side of the fixed plate 39. The output end of the third servo motor 391 passes through the fixed plate 39 and is fixedly connected to the second rotating rod 392. A cleaning brush 393 is fixedly connected to the periphery of the second rotating rod 392.

[0032] The bottom of the threaded rod 33 is rotatably connected to the bottom of the support frame 32, and the rear side of the second rotating rod 392 is rotatably connected to the inside of the fixed plate 39, so that the moving seat 34 can be moved under the action of the threaded rod 33, thereby adjusting the height of the cleaning brush 393. A sliding groove is provided inside the support frame 32, and the moving seat 34 is slidably connected in the sliding groove, so as to ensure the stability of the movement of the moving seat 34 under the action of the sliding groove.

[0033] The cleaning brush 393 is made of soft material, and the water outlet of the spray pipe 38 is set at an angle, which makes it easy to protect the photovoltaic panel when cleaning through the soft material. There are two counterweights 6, which are symmetrically distributed on the left and right sides of the top of the cleaning device body 1, so as to ensure the balance of the cleaning device body 1 when it moves under the action of the counterweights 6.

[0034] Example 2

[0035] Please see Figs. 1-6 Furthermore, based on Embodiment 1, the conveying mechanism 4 further includes a water tank 41, which is fixedly connected to the top of the cleaning device body 1. A filling pipe 42 is fixedly connected to the top of the water tank 41, and a hose 44 is fixedly connected to the front side of the water tank 41. A high-pressure pump 43 is fixedly connected to the periphery of the hose 44, and the high-pressure pump 43 is fixedly connected to the top of the cleaning device body 1.

The hose 44 is fixedly connected to the left side of the water reservoir 35, and the limit frame 45 is fixedly connected to the left side of the support frame 32, so that the hose 44 can be constrained under the action of the limit frame 45 without affecting the up and down movement of the hose 44.

[0036] All electrical components mentioned in this article are electrically connected to the controller and power supply. The control method of this utility model is controlled by the controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The provision of the storage battery is also common knowledge in the field. Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail.

[0037] In actual operation, when this device is used, and when cleaning of photovoltaic panels is required during photovoltaic maintenance, the movable wheels 2 fixedly connected to the bottom of the cleaning device body 1, together with the handle 5 on the left, allow the operator to easily push the device to move within the photovoltaic site and flexibly reach the photovoltaic panel that needs to be cleaned, so that the cleaning device body 1 is near the photovoltaic panel. At the same time, the first servo motor 31 drives the threaded rod 33 to rotate, so that the threaded rod 33 drives the movable seat 34 to move up and down within the support frame 32, thereby adjusting the height of the cleaning brush 393, which can adapt to photovoltaic panels with different installation heights.

[0038] When the height adjustment is completed, the second servo motor 36 drives the first rotating rod 37 to rotate, so that the water storage tank 35 and the cleaning brush 393 can be adjusted in angle. According to the installation angle of the photovoltaic panel, the angle of the cleaning brush 393 is adjusted so that the cleaning brush 393 contacts the top of the photovoltaic panel to ensure that there are no dead angles in the cleaning. When the height and angle adjustment are completed, the water tank 41 is used to store cleaning water. The water source can be easily replenished through the filling pipe 42. The high pressure pump 43 delivers the water in the water tank 41 to the water storage tank 35 through the hose 44 to ensure a continuous and stable water supply during the cleaning process. When the water is delivered into the water storage tank 35, it can be sprayed out through the spray pipe 38 and the nozzle 394 to carry out the cleaning work.

[0039] The water storage device 35 sprays water onto the photovoltaic panel surface through the spray pipe 38 to soften the dirt. At the same time, the third servo motor 391 drives the second rotating rod 392 to rotate, so that the cleaning brush 393 scrubs the wet dirt. The water outlet of the spray pipe 38 is set at an angle, which can more effectively spray water onto the photovoltaic panel surface and enhance the cleaning effect. The bottom nozzle 394 of the water storage device 35 can spray water directly onto the photovoltaic panel surface from below, further increasing the wetting coverage of the dirt on the photovoltaic panel surface and improving the cleaning effect. During the cleaning process, the staff can push the cleaning device body 1 to move slowly and clean the photovoltaic panels one by one.

[0040] Two counterweights 6 are symmetrically arranged on the top of the cleaning device body 1, which effectively lowers the center of gravity of the device, improves the stability of the device during movement and operation, and prevents the equipment from tipping over due to shaking caused by the movement of the cleaning mechanism 3 or the movement of the device.

[0041] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.
