[0042] In combination Figs. 1 to 3 As shown, the photovoltaic cleaning device provided by the embodiment is used for cleaning the photovoltaic panel 10, and the photovoltaic cleaning device can cross the misaligned photovoltaic panel 10 and ensure the running stability when cleaning the misaligned photovoltaic panel 10. Specifically, the photovoltaic cleaning device comprises a support frame 100, a cleaning assembly 200 and a track assembly: the support frame 100 comprises two support rods 110, the two support rods 110 are arranged in parallel and spaced apart along the X direction; the cleaning assembly 200 is arranged between the two support rods 110; the track assembly is provided with multiple groups, the multiple groups of the track assembly are relatively independent and are correspondingly arranged at both ends of the two support rods 110, and when the photovoltaic cleaning device moves on the photovoltaic panel 10, the multiple groups of the track assembly can all adaptively rotate relative to the support frame 100.

[0043] In this embodiment, the support frame 100 further comprises a plurality of reinforcing connecting rods 120, which are arranged along the Y direction at intervals, and the two ends of each reinforcing connecting rod 120 are fixedly connected with two support rods 110 respectively. In this way, the structural strength of the support frame 100 itself is ensured. The track assembly is provided in four groups, and in other embodiments, the number of groups of track assemblies can be appropriately increased or decreased according to actual needs, such as two groups, six groups, eight groups, etc.

[0044] Since the four groups of track assemblies rotatably arranged on the support frame 100 are independent of each other, when the photovoltaic cleaning device moves on the photovoltaic panel 10 and cleans the photovoltaic panel 10, when passing through the misaligned photovoltaic panel 10, the corresponding track assembly is adapted to rotate relative to the support frame 100 according to the misalignment degree between the photovoltaic panels 10, so as to enable the corresponding track assembly to cross the obstacle. In the whole process, the four groups of track assemblies are adapted to independently rotate according to the misalignment degree between the photovoltaic panels 10, so as to avoid the situation that the other track assemblies are partially or entirely suspended and the contact area with the photovoltaic panel 10 is reduced due to the large rotation of one group of track assemblies, thereby maximizing the running stability of the photovoltaic cleaning device when cleaning the misaligned photovoltaic panel 10. The cleaning assembly 200 is arranged according to the prior art, and will not be described here.

[0045] Taking one group of track assemblies as an example, the operation principle of the photovoltaic cleaning device is described in detail.

[0046] Preferably, each track assembly comprises a movement mechanism 300, a mounting plate 400, and a connecting shaft 500; the mounting plate 400 is fixedly connected to the end of the corresponding support rod 110, and the movement mechanism 300 is rotatably connected to the mounting plate 400 through the connecting shaft 500.

[0047] Specifically Fig. 1 As shown in the drawings, in this embodiment, the middle part of the mounting plate 400 is provided with a mounting channel, and the first bearing and the second bearing are arranged at intervals along the length direction of the connecting shaft 500, the connecting shaft 500 is rotatably connected to the mounting plate 400 through the first bearing and the mounting channel, and the movement mechanism 300 is rotatably connected to the connecting shaft 500 through the second bearing, so as to realize the rotatable connection of the movement mechanism 300 to the mounting plate 400. Thus, during the movement of the photovoltaic cleaning device on the photovoltaic panel 10, according to the misalignment of the surface of the photovoltaic panel 10 to be cleaned, the movement mechanism 300 rotates clockwise or counterclockwise by a corresponding angle with the help of the corresponding bearing relative to the mounting plate 400, so that the photovoltaic cleaning device can cross the obstacle with the help of the movement mechanism 300, and the flexibility of the movement mechanism 300 relative to the mounting plate 400 is ensured.

[0048] In some other embodiments, only one bearing can be arranged on the connecting shaft 500, and then the mounting plate 400 is fixedly connected to the connecting shaft 500, and the movement mechanism 300 is rotatably connected to the connecting shaft 500 through the bearing; or the connecting shaft 500 is rotatably connected to the mounting plate 400 through the bearing, and the movement mechanism 300 is fixedly connected to the connecting shaft 500.

[0049] Preferably, the movement mechanism 300 comprises a driving member 310 and a running assembly 320, the running assembly 320 comprising a base plate 321, a driving wheel 322, a driven wheel 323 and a transmission belt 324; the base plate 321 is rotatably connected to the mounting plate 400 through the connecting shaft 500, the driving wheel 322 and the driven wheel 323 are rotatably arranged on the base plate 321 in a Y direction, and an output shaft of the driving member 310 is in transmission connection with the driving wheel 322, and the driven wheel 323 is in transmission connection with the driving wheel 322 through the transmission belt 324.

[0050] Specifically combined Fig. 2 As shown, the middle part of the base plate 321 is connected to the connecting shaft 500, so as to ensure the structural stability of the track assembly relative to the connecting shaft 500. The driving wheel 322 and the driven wheel 323 are rotatably arranged on the base plate 321 in the Y direction and are located on the two sides of the connecting shaft 500, respectively. When the photovoltaic cleaning device needs to clean the photovoltaic panel 10, the driving member 310 starts to operate and drives the driving wheel 322 to rotate, and at the same time, the driven wheel 323 is driven to rotate through the transmission belt 324, so as to realize the operation of the movement mechanism 300 and increase the contact area with the photovoltaic panel 10 through the transmission belt 324, thereby reducing the pressure on the photovoltaic panel 10 and reducing the probability of damaging the photovoltaic panel 10; when passing through the misaligned photovoltaic panel 10, the base plate 321 rotates clockwise or counterclockwise relative to the mounting plate 400 around the connecting shaft 500, thereby driving the running assembly 320 to rotate, so as to facilitate the running assembly 320 to cross the obstacles. The driving wheel 322 and the driven wheel 323 can be arranged as a chain wheel, a gear or a belt pulley according to actual needs, and the transmission belt 324 is correspondingly arranged with the driving wheel 322 and the driven wheel 323. In this embodiment, the driving wheel 322 and the driven wheel 323 are both arranged as gears, specifically, the outer peripheral wall of the driving wheel 322 and the driven wheel 323 is provided with transmission teeth, and the inner wall of the transmission belt 324 is correspondingly provided with transmission splines, and with the operation of the driving member 310, the driving wheel 322 and the driven wheel 323 are in transmission through the meshing of the transmission teeth and the transmission splines at the corresponding positions, so as to further improve the transmission effect. In addition, in this embodiment, the driving member 310 is arranged as a reversible motor, and during the cleaning process, with the forward rotation or reverse rotation of the reversible motor, the photovoltaic cleaning device can advance or retreat in the Y direction, so as to further improve the cleaning effect.

[0051] Preferably, the running assembly 320 further comprises a tensioning wheel 325 and a tensioning piece 326, the tensioning piece 326 is movably arranged on the base plate 321 along the Z direction, and the tensioning wheel 325 is rotatably arranged on the tensioning piece 326 and is in rolling fit with the inner wall of the transmission belt 324.

[0052] Specifically combined Fig. 2 and Fig. 3 As shown in the figure, the base plate 321 is provided with an adjusting avoidance hole, which is arranged as a long hole extending along the Z direction, and the tensioning piece 326 is movably connected to the base plate 321 through the adjusting avoidance hole. Thus, when the transmission belt 324 is stretched due to long-term use, the relative position of the tensioning piece 326 and the base plate 321 can be adjusted to change the pressing force of the tensioning wheel 325 on the transmission belt 324, thereby ensuring the transmission effect between the transmission belt 324 and the driving wheel 322 and the driven wheel 323. In addition, when the tensioning wheel 325 and the transmission belt 324 are in rolling abutment, in order to avoid damage to the photovoltaic panel 10 caused by the tensioning wheel 325, the tensioning piece 326 is arranged on the side of the base plate 321 away from the photovoltaic panel 10. In addition, in order to ensure the pressing effect of the tensioning wheel 325 on the transmission belt 324, a tensioning limiting piece is arranged corresponding to the tensioning piece 326, which is not the focus of the present embodiment and can be arranged according to the prior art, which will not be described here.

[0053] In order to further improve the running stability of the photovoltaic cleaning device when cleaning the photovoltaic panel 10, in the present embodiment, the outer wall of the transmission belt 324 is provided with an anti-skid part (not shown in the figure), which can be composed of a plurality of anti-skid protrusions or a plurality of anti-skid convex tracks arranged at intervals according to actual conditions, which is not limited here.

[0054] During the cleaning process of the photovoltaic cleaning device, when passing through the misaligned photovoltaic panel 10, the track assembly will vibrate with different amplitudes according to the misalignment degree of the photovoltaic panel 10, and the vibration may cause damage to the photovoltaic panel 10. In order to avoid this situation, in the present embodiment, the movement mechanism 300 further comprises a suspension damping assembly 330, which is arranged between the mounting plate 400 and the driven wheel 323.

[0055] Specifically, the suspension damping assembly 330 comprises a suspension damping spring 331, a first connecting rod 332 and a second connecting rod 333; the first end of the first connecting rod 332 is rotatably connected to the mounting plate 400 through a first auxiliary rod 334, and the first auxiliary rod 334 is located above the side of the connecting shaft 500; the first end of the second connecting rod 333 is connected to the driven wheel 323 through a second auxiliary rod 335, and the axis of the second auxiliary rod 335 is misaligned with the center line of the driven wheel 323; the two ends of the suspension damping spring 331 are fixedly arranged on the middle part of the first connecting rod 332 and the middle part of the second connecting rod 333 respectively.

[0056] Specifically combinedFig. 3 As shown, in the embodiment, the auxiliary plate 336 is arranged on the substrate 321 corresponding to the driven wheel 323, and the auxiliary plate 336 is arranged on the side of the substrate 321 away from the driven wheel 323. The second auxiliary rod 335 is arranged on the auxiliary plate 336, and the first end of the second connecting rod 333 is rotatably connected to the second auxiliary rod 335. The first auxiliary rod 334 is arranged on the substrate 321, and the first auxiliary rod 334 is arranged corresponding to the gap between the connecting shaft 500 and the driving wheel 322 and is located above the connecting line of the connecting shaft 500 and the driven shaft. The first end of the first connecting rod 332 is rotatably connected to the first auxiliary rod 334. The middle part of the second connecting rod 333 and the first connecting rod 332 is provided with a limiting baffle. The first end of the suspension damping spring 331 is sleeved on the second end of the second connecting rod 333 and abuts against the limiting baffle arranged on the second connecting rod 333. The second end of the suspension damping spring 331 is sleeved on the second end of the first connecting rod 332 and abuts against the limiting baffle arranged on the first connecting rod 332. When the photovoltaic cleaning device passes through the misaligned photovoltaic panel 10, the driven wheel 323 rotates while being impacted by the force to rotate around the connecting shaft 500 away from the photovoltaic panel 10. At this time, the suspension damping spring 331 is compressed to offset part of the vibration, so that the support frame 100 is not driven to rotate away from the photovoltaic panel 10, thereby achieving the purpose of damping. When the photovoltaic cleaning device has crossed the obstacle, the suspension damping spring 331 is no longer impacted by the force, and the suspension damping spring 331 returns to the original state to drive the driven wheel 323 to return to the original state, that is, the driven wheel 323 rotates while rotating around the connecting shaft 500 under the action of gravity and the elastic force of the suspension damping spring 331 to approach the photovoltaic panel 10, until the connecting line between the centers of the driving wheel 322 and the driven wheel 323 returns to the horizontal state, so as to ensure the stability of the photovoltaic cleaning device running on the non-misaligned photovoltaic panel 10. In addition, since the first end of the second connecting rod 333 is rotatably connected to the second auxiliary rod 335, and the first end of the first connecting rod 332 is rotatably connected to the first auxiliary rod 334, during the compression or self-rebound of the suspension damping spring 331, the two connecting rods can be adapted to rotate relative to the corresponding auxiliary rods to ensure the extension and contraction effect of the suspension damping spring 331 and avoid the bending of the middle part of the suspension damping spring 331 during the extension and contraction of the suspension damping spring 331.

[0057] Further, the second end of the first connecting rod 332 is in a cylindrical shape, and the second end of the second connecting rod 333 is movably inserted into the second end of the first connecting rod 332.

[0058] Specifically, in combination with Fig. 3As shown, the middle part of the second connecting rod 333 is provided with a limiting piece (not shown in the figure), which is arranged close to the limiting baffle on the second connecting rod 333. The second end of the first connecting rod 332 is correspondingly provided with an auxiliary limiting part. When the second end of the second connecting rod 333 is movably inserted into the second end of the first connecting rod 332, the limiting piece and the auxiliary limiting part are in sliding limiting cooperation. By movably inserting the second end of the second connecting rod 333 into the second end of the first connecting rod 332, the extension and contraction path of the suspension damping spring 331 is limited during the extension and contraction process of the suspension damping spring 331, and the situation that the middle part of the suspension damping spring 331 is bent or the suspension damping spring 331 is separated from the first connecting rod 332 or the second connecting rod 333 due to excessive compression of the suspension damping spring 331 is avoided, thereby ensuring the damping effect and further improving the running stability. By sliding limiting cooperation of the limiting piece and the auxiliary limiting part, the relative position of the first connecting rod 332 or the second connecting rod 333 is limited, and during the operation of the track assembly, the first connecting rod 332 and the second connecting rod 333 are prevented from being separated, thereby limiting the relative position of the suspension damping spring 331.

[0059] Preferably, each track assembly further comprises a guide limiting assembly 600, which is arranged on the corresponding mounting plate 400. Two groups of guide limiting assemblies 600 arranged in the X direction are in limiting cooperation with the corresponding two side walls on the photovoltaic panel 10, so as to limit the relative position of the support frame 100 and the photovoltaic panel 10 in the X direction, avoid the situation that the photovoltaic cleaning device is separated from the photovoltaic panel 10 in the X direction under the influence of strong wind and the like, and further improve the running stability and cleaning effect of the photovoltaic cleaning device.

[0060] Specifically, the guide limiting assembly 600 comprises a connecting piece 610 and a limiting wheel 620. The limiting wheel 620 is rotatably connected to the mounting plate 400 through the connecting piece 610 and is in rolling limiting cooperation with the corresponding side wall on the photovoltaic panel 10.

[0061] Specifically, the guide limiting assembly 600 comprises a connecting piece 610 and a limiting wheel 620. The limiting wheel 620 is rotatably connected to the mounting plate 400 through the connecting piece 610 and is in rolling limiting cooperation with the corresponding side wall on the photovoltaic panel 10. Fig. 2 and Fig. 3As shown, the axis of the limiting wheel 620 extends along the Z direction, and when the movement mechanism 300 is in operation, the limiting wheel 620 rolls in limiting cooperation with the corresponding side wall on the photovoltaic panel 10, thereby ensuring the limiting effect on the photovoltaic cleaning device, and meanwhile, avoiding the sliding friction between the guiding and limiting assembly 600 and the corresponding side wall on the photovoltaic panel 10, thereby reducing the operation burden of the corresponding driving member 310. The minimum distance between the two limiting wheels 620 arranged oppositely in the X direction is greater than the width of the photovoltaic panel 10 in the X direction, for example, when the width of the photovoltaic panel 10 in the X direction is 100 cm, the minimum distance between the two limiting wheels 620 arranged oppositely in the X direction is set to 105 cm or 108 cm correspondingly; in this way, the limiting effect is ensured, and meanwhile, the situation that the two limiting wheels 620 arranged oppositely in the X direction extrude and damage the photovoltaic panel 10 due to the slight displacement of the photovoltaic cleaning device in the X direction during the operation of the photovoltaic cleaning device is avoided.

[0062] Obviously, the above embodiments of the present application are merely examples for clearly illustrating the present application, and are not intended to limit the embodiments of the present application. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the protection scope of the present application. Here, it is unnecessary and impossible to enumerate all the embodiments. Any modification, equivalent substitution and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
