[0037] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0038] In some public technical solutions, photovoltaic panel cleaning devices usually use water flushing and rolling brushes to clean the surface of photovoltaic panels. Some debris such as dust or fallen leaves can be easily removed by the above methods. However, some sticky dirt is relatively stubborn and difficult to clean by the above solutions.

[0039] Therefore, the present application adopts a lifting mechanism provided at both ends of the cleaning piece, which can drive the cleaning piece to approach and be close to the surface of the photovoltaic panel to apply pressure to the photovoltaic panel to increase the friction between the cleaning piece and the surface of the photovoltaic panel. The cleaning piece can then rotate itself or reciprocate along the length or width of the photovoltaic panel to effectively clean the dirt.

[0040] like Figure 1-2 As shown, the present application proposes a photovoltaic panel cleaning device, comprising: a support frame 10, a lifting mechanism 20 and a cleaning member 30;

[0041] The support frame 10 is used to install the photovoltaic panel 100; two lifting mechanisms 20 are symmetrically arranged at the edge of the support frame 10; a cleaning member 30 is arranged on the support frame 10, and both ends of the cleaning member 30 are connected to the two lifting mechanisms 20 respectively;

[0042] The lifting mechanism 20 is driven to move the cleaning member 30 closer to or farther from the supporting member, thereby moving closer to or farther from the photovoltaic panel 100 .

[0043] Specifically, the support frame 10 is the basis of the entire cleaning device, and mainly plays the role of fixing, supporting and bearing. The photovoltaic panel 100, the lifting mechanism 20, the cleaning member 30 and other related components are all installed on the support frame 10.

[0044] The support frame 10 has certain strength and stability. The support frame 10 can be a frame-type support frame 10, which is composed of columns and multiple beams, or a cantilever-type support frame 10, which has one or more columns, and a cantilever beam is arranged on the column, and the cantilever beam serves as a mounting platform;

[0045] The support frame 10 may have legs, pillars or supports, and may be horizontally arranged, or inclined, or may be adjustable. For the adjustable support frame 10, when the photovoltaic panel 100 is installed on the support, the inclination angle of the support frame 10 can be adjusted so that the photovoltaic panel 100 can obtain more light.

[0046] Among them, there are two lifting mechanisms 20, which are installed on both sides of the support frame 10 with an interval and relative to each other. They are mainly used to adjust the distance between the cleaning member 30 and the photovoltaic panel 100, and adapt to the dirt layers of different thicknesses by changing the position of the cleaning member 30. The lifting mechanism 20 can be driven by electric, pneumatic or hydraulic drive to realize the up and down movement of the cleaning member 30. When the surface of the photovoltaic panel 100 needs to be cleaned, the lifting mechanism 20 lowers the cleaning member 30 to contact the surface of the photovoltaic panel 100, and adjusts the height as needed, thereby adjusting the pressure applied by the cleaning member 30 on the surface of the photovoltaic panel 100, increasing the friction, and achieving a better cleaning effect.

[0047] The cleaning member 30 is used to clean the surface of the photovoltaic panel 100. It can be in the shape of a long strip, and its length is sufficient to extend to both sides of the photovoltaic panel 100, so as to improve the cleaning efficiency. The cleaning member 30 can be in the form of a roller, and a rotating drive member such as a motor is arranged at either end of the roller to drive the roller to rotate, thereby achieving a rolling cleaning effect;

[0048] A telescopic driving member may also be provided, and the cleaning member 30 may be driven to reciprocate through the telescopic end to achieve a reciprocating friction cleaning effect.

[0049] The cleaning member 30 may be made of a sponge, silicone, or mixed fiber material, and may be a brush, a brush strip, or a wiping cloth or sponge, a roller brush cleaning member 30, or a vibrating cleaning member 30. A vibrating device is provided inside the cleaning member 30, and the vibrating device generates high-frequency vibration to loosen and remove dirt. The above forms may be used in combination to achieve the best efficient cleaning effect.

[0050] Working process:

[0051] Preparation stage: Fix the photovoltaic panel 100 on the support frame 10 to ensure a stable installation.

[0052] Starting cleaning: The operator starts the lifting mechanism 20 to make the cleaning member 30 gradually approach the surface of the photovoltaic panel 100 until the two are in slight contact.

[0053] Adjust the pressure: According to the dirt situation, appropriately adjust the lifting mechanism 20 to increase the contact pressure between the cleaning member 30 and the photovoltaic panel 100 to improve the cleaning effect.

[0054] Perform cleaning: The cleaning member 30 starts to work, which may be rotation, reciprocating movement or other forms of action, to thoroughly remove dirt on the photovoltaic panel 100.

[0055] End of cleaning: After cleaning is completed, the lifting mechanism 20 lifts the cleaning member 30 away from the photovoltaic panel 100 to avoid unnecessary wear or damage.

[0056] During the above working process, two lifting mechanisms 20 are symmetrically installed on the support frame 10, and both ends of the cleaning member 30 are connected to the lifting mechanisms 20 respectively. By starting the lifting mechanisms 20, the cleaning member 30 gradually approaches and closely adheres to the surface of the photovoltaic panel 100. At this time, the cleaning member 30 starts to rotate or move, and the friction between it and the photovoltaic panel 100 is used to remove stubborn stains. Compared with traditional manual or single mechanical cleaning methods, the device can more thoroughly remove various types of dirt, especially those with strong adhesion.

[0057] In some embodiments, the lifting mechanism 20 includes a driving gear 21, a driven gear 22, a driven shaft 23, and an adjustment assembly 24;

[0058] The driving gear 21 is fixedly connected to the end of the cleaning member 30, and the two driven gears 22 are located at the lower end of the driving gear 21 and are symmetrically arranged on both sides of the driving gear 21;

[0059] A driven shaft 23, wherein the two driven shafts 23 respectively penetrate the two driven gears 22, and the two driven shafts 23 are arranged in parallel so that the driven gears 22 rotate around the driven shafts 23 as axes;

[0060] An adjusting assembly 24, the adjusting assembly 24 is movably connected to the driven shaft 23, and the adjusting assembly 24 can adjust the distance between the two driven shafts 23, so that the driving gear 21 is between the two driven gears 22 and rises and falls relative to the driven gear 22, thereby adjusting the height of the cleaning member 30;

[0061] The driving gear 21 is in meshing contact with the driven gear 22 .

[0062] Specifically, the distance between the driven shafts 23 is changed by the adjustment component 24, so as to adjust the spacing between the two driven gears 22. Since the driving gear 21 is disposed between the two driven gears 22 and is in meshing contact with the driven gears 22, after the spacing of the driven gears 22 is adjusted, the driving gear 21 will rise or fall relative to the driven gears 22. For example, if the distance between the two driven gears 22 increases, the driving gear 21 will fall relative to the driven gears 22. On the contrary, if the spacing decreases, the driving gear 21 will rise relative to the driven gears 22. The rise or fall of the driving gear 21 will drive the cleaning member 30 away from or close to the surface of the photovoltaic panel 100.

[0063] The adjustment component 24 is movably connected to the driven shaft 23, and the spacing can be adjusted by means of threads, slide rails, etc. In addition, the operator can drive the adjustment component 24 by means of a manual knob or an electric motor, so as to complete the height adjustment conveniently and quickly.

[0064] In some embodiments, the adjustment assembly 24 includes an adjustment shaft 241 and a rack 242; the adjustment shaft 241 passes through one end of the same side of two parallel driven shafts 23, and is hinged to one of the driven shafts 23, and is threadedly connected to the other driven shaft 23; the rack 242 is fixedly disposed on the support frame 10 and is in meshing contact with the driven gear 22;

[0065] The rack 242 is arranged in a direction parallel to the length direction of the adjusting shaft 241. The adjusting shaft 241 is rotated to make the driven shaft 23 threadedly connected to the adjusting shaft 241 move along the length direction of the adjusting shaft 241, so that the two driven gears 22 are moved closer to or farther from each other.

[0066] Specifically, the adjustment shaft 241 changes the position of the driven shaft 23 by rotating.

[0067] The adjusting shaft 241 passes through one end of the same side of two parallel driven shafts 23, and is hinged to one of the driven shafts 23 and threadedly connected to the other driven shaft 23. By rotating the adjusting shaft 241, the driven shaft 23 moves along the length direction of the adjusting shaft 241.

[0068] Among them, through holes are provided at the ends of the two driven shafts 23, so that the adjusting shaft 241 passes through the two through holes and can rotate in the through holes, a threaded structure is provided in one of the through holes, and a threaded structure corresponding thereto is provided on the adjusting shaft 241, so that when the shaft rotates along the axis, one of the driven shafts 23 does not move, and the other shaft moves along the length direction of the adjusting shaft 241 under the action of the threaded structure, thereby realizing the adjustment function of the spacing of the driven gear 22. The rack 242 is fixedly provided on the support frame 10, and is used for meshing contact with the driven gear 22, so that when the adjusting shaft 241 rotates, thereby driving the driven gear 22 to move, it can move smoothly and accurately along the length direction of the rack 242.

[0069] During the operation, the adjusting shaft 241 is rotated to move the driven shaft 23 threadedly connected to the adjusting shaft 241 outward, the spacing between the two driven gears 22 increases, the driving gear 21 drops relative to the driven gear 22, and the cleaning member 30 drops accordingly, approaching the surface of the photovoltaic panel 100. If the adjusting shaft 241 is rotated to move the driven shaft 23 threadedly connected to the adjusting shaft 241 inward, the spacing between the two driven gears 22 decreases, the driving gear 21 rises relative to the driven gear 22, and the cleaning member 30 rises accordingly, away from the surface of the photovoltaic panel 100.

[0070] In the above process, by rotating the adjustment shaft 241, the spacing of the driven shaft 23 can be precisely adjusted, thereby precisely controlling the height of the cleaning member 30, ensuring the cleaning effect while protecting the photovoltaic panel 100 from damage. The meshing of the rack 242 and the driven gear 22 ensures the smooth rotation of the driven gear 22, thereby improving the stability of the entire system. The height and pressure of the cleaning member 30 can be flexibly adjusted according to different types of photovoltaic panels 100 and dirt conditions to improve cleaning efficiency.

[0071] A servo drive system may also be provided at the ends of the adjustment shafts 241 , and driven by a servo motor, the two adjustment shafts 241 can achieve stable synchronous rotation, thereby synchronously adjusting the heights of the two ends of the cleaning member 30 .

[0072] In some embodiments, a limiting connector 40 is further included, one end of which is hinged to the end of the cleaning member 30 and the other end is hinged to the driven shaft 23 to maintain the distance between the driven shaft 23 and the end of the cleaning member 30 during the adjustment process.

[0073] Specifically, the limiting connector 40 may be a strip connector with a certain length, which is used to maintain the distance between the driven shaft 23 and the end of the cleaning member 30 during the adjustment process, thereby ensuring the stability and accuracy of the cleaning member 30. One end of the limiting connector 40 is fixedly connected to the end of the cleaning member 30. The other end is hinged to the driven shaft 23, allowing the driven shaft 23 to rotate around the hinge point during the adjustment process.

[0074] The limiting connector 40 can be made of high-strength metal materials, such as stainless steel or aluminum alloy, to ensure the stability and durability of the structure. The limiting connector 40 can keep the cleaning member 30 stable during the lifting process, avoiding unnecessary shaking or deviation caused by the movement of the driven shaft 23.

[0075] In some embodiments, a roller 231 is installed at the other end of the same side of the driven shaft 23, and the roller 231 abuts against the support frame 10;

[0076] The rotation axis of the roller 231 is perpendicular to the axis of the driven shaft 23 , so that the driven shaft 23 is in rolling contact with the support frame 10 when moving.

[0077] Specifically, the support frame 10 has a first surface and a second surface that are relatively vertical, wherein the rack 242 is fixedly mounted on the first surface, and the roller 231 abuts against the second surface, so that the rotation axis of the roller 231 is perpendicular to the first surface, and the rolling direction of the roller 231 is the same as the length direction of the rack 242, so that the other end of the driven shaft 23 is in rolling contact with the support frame 10 through the roller 231, so as to improve the stability of the driven gear 22 moving on the rack 242.

[0078] In some embodiments, a first driving member 50 is further included, which is in transmission connection with the end of the cleaning member 30. The first driving member 50 drives the cleaning member 30 to rotate, and the driving gear 21 rotates synchronously with the end of the cleaning member 30, thereby driving the driven wheel to move along the length direction of the rack 242.

[0079] The first driving member 50 is a motor, and the output shaft of the motor is connected to the end of the cleaning member 30 by means of a key or a coupling, and because the driving gear 21 is in meshing contact with the driven gear 22, the driving gear 21 is fixedly connected to the end of the cleaning member 30 and can rotate synchronously. When the driving gear 21 rotates, the two driven gears 22 are driven to rotate in a directional manner, thereby causing the driven gear 22 to move in the opposite direction along the length of the rack 242. During this process, the cleaning member 30 can rotate along its own axis under the driving action of the first driving member 50, and through the cooperation of the driving gear 21 and the driven gear 22, the cleaning member 30 is moved along the length direction of the rack 242, thereby performing rolling cleaning on the entire surface of the photovoltaic panel 100.

[0080] The cleaning member 30 can also be adjusted to a suitable height so as to apply a certain pressure to the surface of the photovoltaic panel 100. Combined with the rotation of the cleaning member 30 itself, the dirt attached to the surface of the photovoltaic panel 100 can be effectively removed during the movement of the cleaning member 30. The rotation direction of the output end or output shaft of the first driving member 50 can also be frequently changed to make the cleaning member 30 reciprocate along the length direction of the rack 242 to repeatedly clean specific areas of the photovoltaic panel 100.

[0081] The first driving member 50 may be controlled by a servo system, which is a method well known to those skilled in the art and will not be elaborated herein.

[0082] It should be noted that the length of the rack 242 is not less than the side length of the photovoltaic panel 100 , so that the moving area of ​​the cleaning member 30 completely covers the surface of the photovoltaic panel 100 .

[0083] In some embodiments, it further includes a water outlet 60, a water return 70, a water storage 80 and a water pump 90;

[0084] The water outlet 60 is arranged on one side of the support frame 10, and the water return portion 70 is arranged on the other side of the support frame 10 opposite to the water outlet 60; the water storage portion 80 is arranged at the lower end of the support frame 10 and is communicated with the water outlet 60 and the water return portion 70 respectively; the water pump 90 is arranged in the water storage portion 80;

[0085] The support frame 10 is tilted, and the side with the water outlet 60 is higher than the side with the water return 70 . The water pump 90 pumps water from the water storage 80 into the water outlet 60 , and flows into the water storage 80 through the water return 70 .

[0086] Specifically, the water outlet 60 is disposed on one side of the support frame 10 and may be a nozzle or a water spray pipe. There may be multiple water outlets 60 so that the water flow is evenly distributed to cover the photovoltaic panel 100 .

[0087] The water return portion 70 is arranged on the other side of the support frame 10 opposite to the water outlet portion 60, collects the water flowing down after cleaning, and guides it back to the water storage portion 80, which can be a drainage trough or a drainage pipe to ensure smooth water flow and avoid water accumulation.

[0088] The water storage portion 80 is disposed at the lower end of the support frame 10 and is used to store cleaning water and transport the water to the water outlet portion 60 through a water pump 90 .

[0089] The water storage part 80 can be a water storage tank with a filter device inside to ensure clean water and avoid clogging of the nozzle. The water pump 90 is arranged in the water storage part 80 to pump the water in the water storage part 80 to the water outlet part 60 to form a water circulation system.

[0090] In some embodiments, the water outlet 60 and the water return 70 are both groove structures, which are connected to the water storage part 80 through the water outlet pipe 61 and the water return pipe 71 respectively, and the water pump 90 is connected to the water outlet pipe 61; wherein, the lifting mechanism 20 is arranged in the groove structure.

[0091] Specifically, the groove structures of the water outlet part 60 and the water return part 70 are both arranged at an angle, and the side wall height of the groove structure of the water outlet part 60 close to the photovoltaic panel 100 is not higher than the surface of the photovoltaic panel 100, and the side wall height away from the photovoltaic panel 100 is higher than the surface of the photovoltaic panel 100. The water pumped into the groove of the water outlet part 60 by the water pump 90 can flow from the side close to the photovoltaic panel 100 to the surface of the photovoltaic panel 100 after being gathered.

[0092] The height of the side wall of the groove structure of the return water part 70 close to the photovoltaic panel 100 is not higher than the surface of the photovoltaic panel 100, and the height of the side wall away from the photovoltaic panel 100 is higher than the surface of the photovoltaic panel 100, so that the groove structure of the return water part 70 can better collect the remaining return water and introduce it into the water storage part 80.

[0093] The two lifting mechanisms 20 are symmetrically arranged in the groove structures of the water outlet 60 and the water return 70.

[0094] By arranging the lifting mechanism 20 in the groove structure, the space utilization is further optimized, making the whole device more compact and efficient.

[0095] In some embodiments, the water storage portion 80 includes a stepped water trough, and the height of the notch 81 of the stepped water trough decreases gradually from the side close to the return water portion 70 to the side of the water outlet portion 60, and the stepped water trough is provided with a filter element 82, which is arranged close to the end of the return water pipe 71 so that the return water flows through the filter element 82 and then returns to the water storage portion 80.

[0096] Specifically, the stepped water trough is composed of a plurality of water troughs of different heights arranged in this way, and the height of the notch 81 decreases successively, wherein the side close to the water return portion 70 is higher and the side close to the water outlet portion 60 is lower.
