[0060] As mentioned in the background technology: Photovoltaic power generation is a device that converts solar energy into electrical energy. The working principle of photovoltaic power generation is based on the photovoltaic effect, using solar cells to directly convert light energy into electrical energy. The cleanliness of photovoltaic panels directly affects the efficiency of photovoltaic power generation. In order to ensure that the photovoltaic panels are clean and free of foreign matter, the photovoltaic panels need to be cleaned in time.

[0061] Existing photovoltaic panel cleaning devices are mostly used to clean from left to right in sequence. However, when the cleaning machine passes from one photovoltaic array to another, the two photovoltaic arrays may not be on the same plane, that is, the height of each photovoltaic array is slightly different, which makes it difficult for the cleaning device to move between the photovoltaic arrays. Not only will the photovoltaic panel cleaning device be damaged, but it may also cause damage to the photovoltaic panels, affecting power generation.

[0062] In order to solve the technical problems raised above, the present application provides a photovoltaic panel cleaning device, which is provided with a movable track, a displacement assembly, a cleaning mechanism and a driving assembly. The movable track is arranged along the length direction of the photovoltaic panel array, and then the displacement assembly drives the cleaning mechanism to move along the length direction of the photovoltaic panel array. Moreover, at least when the displacement assembly drives the cleaning mechanism and the driving assembly to move along the length direction of the movable track, the cleaning mechanism and the driving assembly are suspended relative to the upper surface of the photovoltaic panel, so that the cleaning mechanism and the driving assembly can move back and forth between multiple array-arranged photovoltaic panels, thereby avoiding damage to the cleaning device or even damage to the photovoltaic panels due to the height difference between adjacent photovoltaic panels.

[0063] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

The driving assembly 400 is configured to drive the cleaning mechanism 300 to reciprocate along the tilt direction of the photovoltaic panel 600 . The cleaning mechanism 300 is configured to clean the upper surface of the photovoltaic panel 600 .

[0068] At least when the displacement assembly 200 drives the cleaning mechanism 300 and the driving assembly 400 to move along the length direction of the moving track 100 , the cleaning mechanism 300 and the driving assembly 400 are suspended relative to the upper surface of the photovoltaic panel 600 .

[0069] The photovoltaic panels 600 are arranged in an array, that is, the photovoltaic panels 600 in the same array are arranged along a straight line.

[0070] The length direction of the photovoltaic panel 600 array is Figure 1 The X direction in .

[0071] The tilt direction of the photovoltaic panel is Figure 1in the Y direction.

[0072] The spacing between the cleaning mechanism 300 and the driving assembly 400 suspended relative to the upper surface of the photovoltaic panel 600 is greater than the height difference between adjacent photovoltaic panels 600, so as to avoid the cleaning mechanism 300 and the driving assembly 400 from being damaged when passing between two adjacent photovoltaic panels 600 due to the height difference between adjacent photovoltaic panels 600.

[0073] Exemplarily, the driving assembly 400 and the cleaning mechanism 300 are always suspended above the upper surface of the photovoltaic panel 600 , wherein the cleaning mechanism 300 can blow air to blow away foreign matter on the upper surface of the photovoltaic panel 600 .

[0074] Exemplarily, when the cleaning mechanism 300 is located at the top of the photovoltaic panel 600, it is suspended on the upper surface of the photovoltaic panel 600; when the cleaning mechanism 300 moves obliquely downward along the photovoltaic panel 600, it abuts against the upper surface of the photovoltaic panel 600, thereby cleaning the upper surface of the photovoltaic panel 600.

[0075] By adopting the above technical scheme, by setting up a movable track 100, a displacement component 200, a cleaning mechanism 300 and a driving component 400, by arranging the movable track 100 along the length direction of the photovoltaic panel 600 array, and then driving the cleaning mechanism 300 to move along the length direction of the photovoltaic panel 600 array through the displacement component 200, and at least when the displacement component 200 drives the cleaning mechanism 300 and the driving component 400 to move along the length direction of the movable track 100, the cleaning mechanism 300 and the driving component 400 are suspended relative to the upper surface of the photovoltaic panel 600, so that the cleaning mechanism 300 and the driving component 400 can reciprocate between multiple array-arranged photovoltaic panels 600, thereby avoiding damage to the cleaning device or even damage to the photovoltaic panel 600 due to the height difference between adjacent photovoltaic panels 600.

[0076] In some embodiments, reference Figure 1 and Figure 2 The mobile track 100 includes a track bracket 110 and a track body 120. The track bracket 110 is used to be installed on the ground. The track body 120 is installed on the track bracket 110. A plurality of travel switches 130 are arranged on the track body 120. The travel switches 130 are arranged corresponding to the photovoltaic panels 600. The travel switches 130 are configured to control the opening and closing of the displacement assembly 200.

[0077] By adopting the above technical solution, the track bracket 110 and the track body 120 are provided to ensure the stability of the moving track 100, thereby ensuring the stability of the displacement assembly 200 moving on the moving track 100. By providing a travel switch 130, and the travel switch 130 is provided corresponding to the photovoltaic panel 600, when the displacement assembly 200 moves to the travel switch 130, the displacement assembly 200 drives the cleaning mechanism 300 and the driving assembly 400 to be located exactly on the upper end surface of the photovoltaic panel 600, so that the cleaning mechanism 300 cleans the upper end surface of the photovoltaic panel 600.

[0078] In some embodiments, reference Figure 1 and Figure 2 The displacement assembly 200 includes at least two displacement wheels 210 and at least two displacement motors 220. Each displacement wheel 210 is connected to the moving track 100. Each displacement motor 220 is correspondingly connected to each displacement wheel 210. The displacement motor 220 is configured to drive the displacement wheel 210 to move along the length direction of the moving track 100.

[0079] Each displacement wheel 210 is connected to the driving assembly 400 .

[0080] Exemplarily, the displacement wheel 210 is a gear, and the track bracket 110 has teeth meshing with the gear. The cooperation between the gear and the teeth improves the stability of the displacement assembly 200 moving on the moving track 100.

[0081] Exemplarily, two displacement wheels 210 are provided, and two displacement motors 220 are also provided, and each displacement wheel 210 is connected to a displacement motor 220 .

[0082] Exemplarily, the displacement wheel 210 is connected to the driving assembly 400 by bolts, so as to facilitate installation and disassembly of the displacement assembly 200 and the driving assembly 400 .

[0083] By adopting the above technical solution, by setting the displacement wheel 210 and the displacement motor 220, the displacement motor 220 drives the displacement wheel 210 to rotate, so that the displacement wheel 210 moves in the moving track 100, thereby driving the driving component 400 and the cleaning mechanism 300 to move along the moving track 100, so that the driving component 400 and the cleaning component 320 can reciprocate between adjacent photovoltaic panels 600.

[0084] In some embodiments, reference Figure 2 , Figure 3 and Figure 4 The cleaning mechanism 300 includes a cleaning frame 310, a cleaning component 320 and at least three walking components 330.

[0085] The cleaning frame 310 is connected to the driving assembly 400 .

[0086] The cleaning assembly 320 is disposed on the cleaning frame 310 , and the cleaning assembly 320 is configured to clean the upper surface of the photovoltaic panel 600 .

[0087] Each traveling assembly 330 is installed on the cleaning frame 310 , and the cleaning assembly 320 is located between the traveling assemblies 330 . The traveling assemblies 330 rotate to abut against the upper surface of the photovoltaic panel 600 . The traveling assemblies 330 are configured to support the cleaning frame 310 .

[0088] Exemplarily, the cleaning frame 310 is a shell having a lower opening, and the cleaning component 320 and the traveling component 330 are located in the shell and protrude from the lower opening of the shell.

[0089] Exemplarily, four walking assemblies 330 are provided, and the four walking assemblies 330 are respectively located at the four end corners of the cleaning frame 310 , thereby improving the supporting stability of the walking assemblies 330 on the cleaning frame 310 .

[0090] By adopting the above technical solution, a cleaning frame 310, a cleaning component 320 and a walking component 330 are set, and the cleaning component 320 and the walking component 330 are installed in the cleaning frame 310. The walking component 330 drives the cleaning component 320 to move along the upper surface of the photovoltaic panel 600. During the movement, the cleaning component 320 cleans the upper surface of the photovoltaic panel 600.

[0091] In some embodiments, reference Figure 3 The cleaning assembly 320 includes a cleaning roller 321 and a cleaning motor 322 . The cleaning roller 321 is rotatably mounted on the cleaning frame 310 . The cleaning motor 322 is fixed on the cleaning frame 310 . The output shaft of the cleaning motor 322 is coaxially connected to the cleaning roller 321 .

[0092] Exemplarily, the cleaning roller 321 has bristles, and the bristles abut against the upper surface of the photovoltaic panel 600 , thereby improving the cleaning effect of the cleaning roller 321 on the photovoltaic panel 600 .

[0093] By adopting the above technical solution, when it is necessary to start the cleaning component 320 to clean the photovoltaic panel 600, the cleaning motor 322 is started, the cleaning motor 322 drives the cleaning roller 321 to rotate, and the cleaning roller 321 abuts against the upper surface of the photovoltaic panel 600, thereby achieving the cleaning of the upper surface of the photovoltaic panel 600.

[0094] In some embodiments, reference Figure 3 The walking assembly 330 includes a walking frame 331, walking wheels 332 and tracks 333. The walking frame 331 is installed on the cleaning frame 310, the walking wheels 332 are rotatably installed on the walking frame 331, and the tracks 333 are sleeved on the walking wheels 332. The tracks 333 are in contact with the upper surface of the photovoltaic panel 600.

[0095] Exemplarily, the traveling frame 331 is mounted on the traveling frame 331 by bolts, so as to facilitate the installation of the traveling assembly 330 on the traveling frame 331 .

[0096] Exemplarily, the walking wheel 332 includes two wheels, the axes of the two wheels are parallel, and the track 333 is mounted on the two wheels, thereby increasing the contact area between the walking component 330 and the upper surface of the photovoltaic panel 600, and avoiding excessive pressure of the walking component 330 on the upper surface of the photovoltaic panel 600, thereby causing damage to the photovoltaic panel 600.

[0097] By adopting the above technical solution, by setting up the walking frame 331, walking wheels 332 and tracks 333, the stability of the walking component 330 on the photovoltaic panel 600 is improved, and the walking component 330 is prevented from exerting excessive pressure on the upper surface of the photovoltaic panel 600, thereby preventing the photovoltaic panel 600 from being damaged.

[0098] In some embodiments, reference Figure 3 The walking assembly 330 also includes a shock-absorbing spring 334, and a shock-absorbing spring 334 is provided on at least one of between the walking frame 331 and the cleaning frame 310 and between the walking frame 331 and the walking wheel 332.

[0099] Exemplarily, the shock absorbing spring 334 is disposed between the traveling frame 331 and the traveling wheel 332 .

[0100] By adopting the above technical solution and providing the shock-absorbing spring 334 , the stability of the walking component 330 walking on the photovoltaic panel 600 is improved.

[0101] In some embodiments, reference Figure 4 The driving assembly 400 includes a driving bin 410, a winding roller 420, a winding motor 430 and a flexible connecting member 440. The driving bin 410 is connected to the displacement assembly 200. The winding roller 420 is rotatably installed in the driving bin 410. The winding motor 430 is fixed in the driving bin 410 and connected to the winding roller 420. One end of the flexible connecting member 440 is connected to the winding roller 420, and the other end is connected to the cleaning mechanism 300.

[0102] The winding motor 430 is configured to drive the winding roller 420 to rotate bidirectionally, so as to drive the cleaning mechanism 300 to move back and forth along the tilt direction of the photovoltaic panel 600 through the flexible connector 440 .

[0103] Exemplarily, the driving chamber 410 is connected to the displacement assembly 200 by bolts. The driving chamber 410 has a receiving chamber, the winding roller 420 is installed in the receiving chamber, and the receiving chamber is used to receive the flexible connector 440.

[0104] Exemplarily, the flexible connector 440 is made of flexible plastic.

[0105] By adopting the above technical solution, when it is necessary to start the driving component 400 to drive the cleaning mechanism 300 to move, the winding motor 430 is started, and the winding motor 430 drives the winding roller 420 to rotate. During the rotation, the winding roller 420 will reel in or release the flexible connector 440. When reeling in the flexible connector 440, the flexible connector 440 drives the cleaning mechanism 300 to move upward along the upper surface of the photovoltaic panel 600. When releasing the flexible connector 440, the cleaning mechanism 300 can move downward along the upper surface of the photovoltaic panel 600 under the action of its own gravity, thereby realizing the control of the cleaning mechanism 300 to move back and forth along the inclined direction of the upper surface of the photovoltaic panel 600.

[0106] In some embodiments, reference Figure 4 The driving assembly 400 also includes a load-bearing plate 450, which is installed on one side of the driving bin 410 close to the cleaning mechanism 300. The load-bearing plate 450 is spaced apart and parallel to the upper surface of the photovoltaic panel 600. The load-bearing plate 450 is configured so that when the winding motor 430 drives the cleaning mechanism 300 to move upward along the inclined direction of the photovoltaic panel 600, the cleaning mechanism 300 can move onto the load-bearing plate 450 so that the cleaning mechanism 300 is suspended relative to the upper surface of the photovoltaic panel 600.

[0107] Exemplarily, the load-bearing plate 450 matches the track 333 in the cleaning mechanism 300 , wherein the height of the load-bearing plate 450 is lower than half the height of the running wheel 332 in the track 333 , so that when the track 333 abuts against the load-bearing plate 450 , the track 333 can move above the load-bearing plate 450 .

[0108] By adopting the above technical solution and setting a load-bearing plate 450, after the cleaning mechanism 300 moves to the load-bearing plate 450, the cleaning mechanism 300 can be pulled by the flexible connector 440 and moved to above the load-bearing plate 450, so that the cleaning mechanism 300 is suspended relative to the upper surface of the photovoltaic panel 600, thereby avoiding collision with the photovoltaic panel 600 when the cleaning mechanism 300 moves between two adjacent photovoltaic panels 600, thereby damaging the cleaning mechanism 300 and the photovoltaic panel 600.

[0109] In some embodiments, reference Figure 1 and Figure 5 The photovoltaic panel cleaning device also includes a plurality of blocking components 500, each of which is installed on a side of the photovoltaic panel 600 that is tilted downward. The blocking component 500 is configured to abut against the blocking component 500 when the cleaning mechanism 300 moves to the lower end of the photovoltaic panel 600, so as to prevent the cleaning mechanism 300 from separating from the photovoltaic panel 600.

[0110] Exemplarily, the blocking assembly 500 includes two blocking plates, which are respectively installed at two ends of a side of the photovoltaic panel 600 that is tilted downward by bolts, and the blocking plates are located above the upper end surface of the photovoltaic panel 600 .

[0111] By adopting the above technical solution and providing the blocking assembly 500 , it is possible to prevent the cleaning mechanism 300 from being separated from the photovoltaic panel 600 , thereby improving the stability of the cleaning mechanism 300 moving on the photovoltaic panel 600 .
