Description

Technical Field

[0001] This invention relates to the field of photovoltaic cell cleaning technology, and in particular to a cleaning device for photovoltaic panels. Background Technology

[0002] Photovoltaic panels, also known as solar panels, are typically installed outdoors. They convert solar energy into electricity. Outdoor photovoltaic panels are prone to dust accumulation and require regular cleaning and maintenance to ensure their power generation efficiency. Currently, cleaning of photovoltaic panels relies on manual sweeping or cleaning equipment. Current equipment includes cleaning vehicles and devices that clamp the panels, but these methods are difficult to adjust in terms of angle and height, making them unsuitable for cleaning photovoltaic panels in different installation locations. This results in low cleaning efficiency and is not ideal for cleaning large quantities of photovoltaic panels. Summary of the Invention

[0003] The purpose of this invention is to at least solve one of the technical problems existing in the prior art, and to provide a cleaning device for photovoltaic panels that facilitates the adjustment of the position of the cleaning device relative to the photovoltaic panels, thereby improving the applicability of the cleaning device for photovoltaic panels and increasing the cleaning efficiency.

[0004] According to an embodiment of the present invention, a cleaning device for photovoltaic panels is provided, comprising: a vehicle body, a leveling component, a height adjusting component, and a cleaning component; the vehicle body is movable on the ground, and the vehicle body has a first direction and a second direction perpendicular to each other in a horizontal plane; the leveling component is located on the upper surface of the vehicle body, and the leveling component includes a connecting seat, at least two adjusting seats, and at least two connecting rods, the at least two adjusting seats being arranged at intervals along the first direction, the two ends of the connecting rods being rotatably connected to the adjusting seats and the connecting seats respectively, one end of each of the two connecting rods being rotatably connected to the connecting seats respectively, and the other end of each of the two connecting rods being rotatably connected to the two adjusting seats respectively; and the two adjusting seats are capable of moving closer and further apart relative to each other along the first direction, thereby driving the connecting seats to move relative to the vehicle body in the second direction; the height adjusting component is located on the connecting seats, and at least part of the height adjusting component is capable of moving relative to the vehicle body along the height direction; the cleaning component is rotatably connected to the height adjusting component, enabling the cleaning component to adjust its angle relative to the horizontal plane.

[0005] As an example of this application, at least two connecting seats are provided, the two connecting seats are arranged at intervals in the second direction, and each connecting seat is rotatably connected to two connecting rods. The corresponding two adjusting seats can move closer and further away from each other in the first direction, and can drive the corresponding two connecting seats to move closer and further away from each other in the second direction.

[0006] As an example of this application, the leveling assembly further includes a guide mechanism comprising a guide rod and a guide sleeve. The guide rod is arranged along a second direction and passes through the guide sleeve. The guide mechanism is located between two connecting seats arranged at intervals in the second direction. One end of the guide rod is fixedly connected to one of the connecting seats, and the end of the guide sleeve away from the guide rod is fixedly connected to the other connecting seat.

[0007] As an example of this application, the vehicle body further includes a guide rail arranged along the first direction, and the adjustment seat is slidably connected to the guide rail.

[0008] As an example of this application, the leveling assembly further includes a rotating rod arranged along a first direction, the rotating rod being rotatably connected to the vehicle body and capable of rotating around its central axis, and the outer surfaces of both ends of the rotating rod being provided with at least two threaded segments with opposite thread directions, and the two adjusting seats respectively engaging with the two threaded segments by screwing.

[0009] As an example of this application, the cleaning assembly includes a swing arm, a cleaning roller, and a cleaning strip. The swing arm is rotatably connected to the height adjustment assembly, allowing the swing arm to rotate relative to the height adjustment assembly about the first direction or the second direction. The cleaning strip is connected to the outer periphery of the cleaning roller, and the cleaning roller is connected to the swing arm. The cleaning roller is capable of rotating about the central axis of the cleaning roller to drive the cleaning strip to rotate.

[0010] As an example of this application, there are multiple cleaning strips, which are arranged circumferentially at intervals with the cleaning roller. The cleaning roller is provided with a water inlet, a cleaning channel and a water outlet that are connected in sequence. The water inlet is used to input cleaning liquid. The water inlet and the water outlet are located on the outer peripheral wall of the cleaning roller. The water inlet is located at the end of the cleaning roller near the swing arm, and the water outlet is located at least between two adjacent cleaning strips.

[0011] As an example of this application, the cleaning assembly further includes a collar that is rotatably and sealingly connected to the outer peripheral wall of the cleaning roller. The collar has a receiving cavity inside, the collar wraps around the water inlet hole, and the receiving cavity communicates with the water inlet hole.

[0012] As an example of this application, it also includes a carrier tank for loading the cleaning fluid, the carrier tank being located on the vehicle body, and the carrier tank being connected to the receiving cavity via a water pipe.

[0013] As an example of this application, it also includes a roller rotatably connected to the vehicle body, the rotation of which can drive the vehicle body to move.

[0014] The photovoltaic panel cleaning device of the present invention has at least the following beneficial effects: A horizontal adjustment component is located on the upper surface of the vehicle body. The horizontal adjustment component includes a connecting seat, at least two adjusting seats, and at least two connecting rods. The at least two adjusting seats are spaced apart along a first direction. One end of each of the two connecting rods is rotatably connected to the connecting seat, and the other end of each connecting rod is rotatably connected to the two adjusting seats. The two adjusting seats can move closer to and further away from each other along the first direction, driving the two connecting rods connected to them to move, thereby driving the connecting seats to move relative to the vehicle body in a second direction, thus adjusting the position of the connecting seats relative to the vehicle body in the second direction. Since the height adjustment component is located on the connecting seat, and the cleaning component is rotatably connected to the height adjustment component, the connecting seat of the horizontal adjustment component can drive the height adjustment component and the cleaning component to move relative to the vehicle body along the second direction. Since at least a portion of the height adjustment component can move relative to the vehicle body along the height direction, it drives the cleaning component to move relative to the vehicle body along the height direction. Since the cleaning component is rotatably connected to the height adjustment component, the cleaning component can adjust its angle relative to the horizontal plane, thereby allowing the angle of the cleaning component relative to the photovoltaic panel to be adjusted. The cleaning assembly is adjusted to fit against the photovoltaic panel. The vehicle moves on the ground, causing the cleaning assembly to move relative to the photovoltaic panel surface for cleaning. Horizontal and height adjustment components, working in conjunction with the rotation of the cleaning assembly relative to the height adjustment component, allow for easy adjustment of the cleaning assembly's position relative to the photovoltaic panel. This makes the cleaning device suitable for photovoltaic panels in different installation locations, improving cleaning efficiency. Attached Figure Description

[0020] In the description of this invention, unless otherwise explicitly defined, terms such as "set up," "install," and "connect" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0021] Reference Figure 1 and Figure 2This invention provides a photovoltaic panel cleaning device, including a vehicle body 100, a horizontal adjustment assembly 200, a height adjustment assembly 300, and a cleaning assembly 400. The vehicle body 100 is movable on the ground. The vehicle body 100 has a first direction and a second direction that are perpendicular to each other in a horizontal plane. The horizontal adjustment assembly 200 is mounted on the upper surface of the vehicle body 100. The horizontal adjustment assembly 200 includes a connecting seat 230, at least two adjusting seats 210, and at least two connecting rods 220. The two ends of the connecting rods 220 are rotatably connected to the adjusting seats 210 and the connecting seat 230, respectively. One end of each of the two connecting rods 220 is rotatably connected to the connecting seat 230, and the other end of each of the two connecting rods 220 is rotatably connected to the two adjusting seats 210. The at least two adjusting seats 210 are arranged at intervals along the first direction. The two adjusting seats 210 can move closer and further away from each other along the first direction, driving the two connecting rods 220 connected to them to move, thereby driving the connecting seat 230 to move relative to the vehicle body 100 in the second direction.

[0022] It is understood that two adjusting seats 210 form a group, and at least one group of adjusting seats 210 is provided, with at least one group of adjusting seats 210 arranged at intervals along the first direction. Two connecting rods 220 form a group, with one end of each of the two connecting rods 220 in the group rotatably connected to a connecting seat 230, and the other end of each connecting rod 220 rotatably connected to two adjusting seats 210 in the group, so that the two adjusting seats 210 in the group move relatively closer and further apart in the first direction, thereby driving the two connecting rods 220 to move, and in turn driving the connecting seat 230 to move.

[0023] When the two adjusting seats 210 move closer to each other in a first direction, they cause the two connecting rods 220 connected to them to move, which in turn causes the connecting seats 230 connected to the two connecting rods 220 to move away from the vehicle body 100 in a second direction. When the two adjusting seats 210 move away from each other, they cause the two connecting rods 220 connected to them to move, which in turn causes the connecting seats 230 connected to the two connecting rods 220 to move closer to the vehicle body 100 in a second direction. The cleaning assembly 400 is rotatably connected to the height adjusting assembly 300. The height adjusting assembly 300 is located on the connecting seat 230, and at least part of the height adjusting assembly 300 can move relative to the vehicle body 100 in the height direction, so as to cause the cleaning assembly 400 to move relative to the vehicle body 100 in the height direction. By the two adjusting seats 210 being able to move closer and farther apart in a first direction, the connecting seat 230 is moved relative to the vehicle body 100 in a second direction, so as to cause the height adjusting assembly 300 and the cleaning assembly 400 to move relative to the vehicle body 100, thereby allowing the cleaning assembly 400 to adjust its position relative to the photovoltaic panel in the second direction. The height adjustment component 300 can drive the cleaning component 400 to move along the height direction, allowing the cleaning component 400 to adjust its position relative to the photovoltaic panel along the height direction. The cleaning component 400 is rotatably connected to the height adjustment component 300, allowing the cleaning component 400 to adjust its angle relative to the horizontal plane, and thus its angle relative to the photovoltaic panel. Adjusting the cleaning component 400 to fit against the photovoltaic panel, and enabling the vehicle body 100 to move on the ground, allows the cleaning component 400 to move against and relative to the surface of the photovoltaic panel for cleaning, facilitating operation. The ability of the vehicle body 100 to move on the ground improves the portability of this photovoltaic panel cleaning device. By cooperating with the horizontal adjustment component 200 and the height adjustment component 300 to rotate the cleaning component 400, the position of the cleaning component 400 relative to the photovoltaic panel can be adjusted, improving the convenience of adjusting the cleaning component 400 to fit the photovoltaic panel. This allows the cleaning component 400 to fit photovoltaic panels at different installation positions and angles, thereby improving the applicability of the cleaning device proposed in this application, reducing the reliance on manual labor during the adjustment process, and improving cleaning efficiency.

[0024] Reference Figure 1 and Figure 2In some embodiments of the present invention, the two connecting rods 220 are respectively a first rod 221 and a second rod 222, and the first rod 221 and the second rod 222 form a set of connecting rods 220. The two sets of adjusting seats 210 are respectively a first adjusting seat 211 and a second adjusting seat 212, and the first adjusting seat 211 and the second adjusting seat 212 form a set of connecting seats 230. The first adjusting seat 211 and the second adjusting seat 212 can move closer to each other and further apart along a first direction. One end of the first rod 221 and the second rod 222 are respectively rotatably connected to the connecting seat 230. The end of the first rod 221 away from the connecting seat 230 is rotatably connected to the first adjusting seat 211, and the end of the second rod 222 away from the connecting seat 230 is rotatably connected to the second adjusting seat 212. When the first adjusting seat 211 and the second adjusting seat 212 move closer to each other along the first direction, the first rod 221 and the second rod 222 move closer to each other, thereby causing the connecting seat 230 connected to the first rod 221 and the second rod 222 to move away from the vehicle body 100 along the second direction; when the first adjusting seat 211 and the second adjusting seat 212 move away from each other along the second direction, the first rod 221 and the second rod 222 move, thereby causing the connecting seat 230 connected to the first rod 221 and the second rod 222 to move towards the vehicle body 100. The relative movement of the first adjusting seat 211 and the second adjusting seat 212 along the first direction adjusts the position of the connecting seat 230 relative to the vehicle body 100 in the second direction, causing the height adjustment component 300 connected to the connecting seat 230 and the cleaning component 400 connected to the height adjustment component 300 to move, allowing the cleaning component 400 to be adjusted to its position relative to the photovoltaic panel in the horizontal plane.

[0025] Reference Figure 1 and Figure 2In some embodiments of the present invention, the vehicle body 100 has a first direction, a second direction, and a third direction that are mutually perpendicular to each other. The first and second directions are perpendicular to each other in the horizontal plane, and the third direction is the height direction. At least two connecting seats 230 are provided. The two connecting seats 230 are arranged at intervals along the second direction, and each connecting seat 230 is rotatably connected to two connecting rods 220. The corresponding two adjusting seats 210 move closer and further apart along the first direction, which can drive the corresponding two connecting seats 230 to move closer and further apart along the second direction. Two connecting seats 230 arranged at intervals along the second direction are respectively a first connecting seat 231 and a second connecting seat 232. The first connecting seat 231 is rotatably connected to two connecting rods 220. The two sets of connecting rods 220 connected to the first connecting seat 231 are respectively the first rod 221 and the second rod 222. The second connecting seat 232 is rotatably connected to two other sets of connecting rods 220. The two sets of connecting rods 220 connected to the second connecting seat 232 are respectively the third rod 223 and the fourth rod 224. The end of the first rod 221 away from the first connecting seat 231 is rotatably connected to the first adjusting seat 211. The end of the second rod 222 away from the first connecting seat 231 is rotatably connected to the second adjusting seat 212. The end of the third rod 223 away from the second connecting seat 232 is rotatably connected to the first adjusting seat 211. The end of the fourth rod 224 away from the second connecting seat 232 is rotatably connected to the second adjusting seat 212. When the first adjusting seat 211 and the second adjusting seat 212 move closer to each other in the first direction, the first rod 221 and the second rod 222 move closer to each other, and the third rod 223 and the fourth rod 224 move closer to each other, thereby causing the first connecting seat 231 and the second connecting seat 232 to move away from each other in the second direction, so that both the first connecting seat 231 and the second connecting seat 232 move away from the vehicle body 100; when the first adjusting seat 211 and the second adjusting seat 212 move away from each other in the first direction, the first rod 221 and the second rod 222 drive the first connecting seat 231 to move, and the third rod 223 and the fourth rod 224 drive the second connecting seat 232 to move, thereby causing the first connecting seat 231 and the second connecting seat 232 to move closer to each other in the second direction, so that both the first connecting seat 231 and the second connecting seat 232 move closer to the vehicle body 100. By moving the first adjusting seat 211 closer to and further away from the second adjusting seat 212, the first connecting seat 231 and the second connecting seat 232 move closer to and further away in the second direction, thereby moving the cleaning components 400 connected to the first connecting seat 231 and the second connecting seat 232 respectively. This allows the two adjusting seats 210 to adjust the positions of the two sets of cleaning components 400 spaced apart in the second direction relative to the photovoltaic panels, improving adjustment efficiency. By arranging the two connecting seats 230 spaced apart along the second direction, and with the cleaning components 400 located on the connecting seats 230, the cleaning device can simultaneously clean two adjacent sets of photovoltaic panels along the second direction, improving cleaning efficiency.

[0026] It is understood that in some embodiments of the present invention, at least two sets of height adjustment components 300 are provided, with at least one set of height adjustment components 300 located on one of the connecting seats 230, and at least two sets of cleaning components 400 are provided, with at least one set of cleaning components 400 located on one of the height adjustment components 300. The number of height adjustment components 300 and cleaning components 400 can be selected according to actual applications, and this application does not limit them.

[0027] Reference Figure 1 In some embodiments of the present invention, the photovoltaic panel cleaning device proposed in this application further includes rollers 130. The rollers 130 are rotatably connected to the vehicle body 100. The rotation of the rollers 130 drives the vehicle body 100 to move, allowing the vehicle body 100 to move flexibly on the ground. This makes the photovoltaic panel cleaning device applicable to uneven outdoor environments. The rollers 130 move the vehicle body 100, moving the photovoltaic panel cleaning device to the corresponding position on the photovoltaic panel. After adjusting the cleaning component 400 to fit against the photovoltaic panel, the rollers 130 further move the vehicle body 100, causing the cleaning component 400 to move and clean the surface of the photovoltaic panel. The rollers 130 on the vehicle body 100 improve the portability and flexibility of the photovoltaic panel cleaning device, increasing manual labor intensity.

[0028] It is understood that in some embodiments of the present invention, the roller 130 is provided with a braking component, which enables the roller 130 to be braked, thereby allowing the photovoltaic panel proposed in this application to remain stable when not in use.

[0029] It is understood that in some embodiments of the present invention, the roller 130 may be a caster wheel to improve the flexibility of the vehicle body 100 in movement.

[0030] It is understood that in some embodiments of the present invention, the roller 130 is connected to a drive device to drive the roller 130 to rotate, thereby driving the cleaning device to move, improving the automation of the cleaning device and reducing reliance on manual labor.

[0031] Reference Figure 1 In some embodiments of the present invention, a photovoltaic panel cleaning device proposed in this application further includes a handle 140, which is installed on the vehicle body 100 and is used for manual gripping. By gripping the handle 140, the manual person can easily push the vehicle body 100, thereby improving the convenience of pushing the vehicle body 100.

[0032] Reference Figure 2In some embodiments of the present invention, it is understood that the horizontal adjustment assembly 200 further includes a guide mechanism 240, which includes a guide rod 241 and a guide sleeve 242. The guide rod 241 is arranged along a second direction and passes through the guide sleeve 242. Both ends of the guide mechanism 240 are respectively connected to two connecting seats 230 spaced apart in the second direction. One end of the guide rod 241 is fixedly connected to one of the connecting seats 230, and the other end of the guide rod 241 is inserted into the guide sleeve 242. The end of the guide sleeve 242 away from the guide rod 241 is fixedly connected to the other connecting seat 230. (Refer to...) Figure 2 The guide mechanism 240 is located between the first connecting seat 231 and the second connecting seat 232. One end of the guide rod 241 is fixedly connected to the second connecting seat 232, and the other end of the guide rod 241 is inserted into the guide sleeve 242. The end of the guide sleeve 242 away from the guide rod 241 is fixedly connected to the first connecting seat 231. When the first adjusting seat 211 and the second adjusting seat 212 move closer to each other and further away from each other, the first connecting seat 231 and the second connecting seat 232 move closer to each other or further away from each other. The guide rod 241 slides relative to the guide sleeve 242, which improves the stability of the movement of the first connecting seat 231 and the second connecting seat 232, and reduces the possibility of the height adjustment component 300 and the cleaning component 400 connected to the connecting seat 230 shaking during the movement of the connecting seat 230.

[0033] Reference Figure 2 In some embodiments of the present invention, the vehicle body 100 further includes a guide rail 110 arranged along a first direction. The guide rail 110 is arranged along the first direction, and the adjustment seat 210 is slidably connected to the guide rail 110, so that two adjacent sets of adjustment seats 210 can move closer or further away from each other along the first direction, thereby improving the stability of the movement of the adjustment seat 210.

[0034] Reference Figure 2 In some embodiments of the present invention, the horizontal adjustment assembly 200 further includes a rotating rod 250 arranged along a first direction. The rotating rod 250 is rotatably connected to the vehicle body 100 and is capable of rotating around its central axis. The outer surfaces of both ends of the rotating rod 250 are provided with at least two threaded segments with opposite thread directions. The adjusting seat 210 is provided with threaded holes, and the rotating rod 250 passes through the threaded holes of two adjusting seats 210 in a set. The two adjusting seats 210 are respectively screwed into the threaded segments with opposite thread directions. The rotation of the rotating rod 250 causes the two adjusting seats 210 in the set to move closer or further apart, facilitating the adjustment of the relative movement of the two adjusting seats 210 in the set and improving adjustment efficiency.

[0035] It is understood that the rotating rod 250 is connected to a drive device, which is used to drive the rotating rod 250 to rotate, making it easier to adjust the rotation of the rotating rod 250 and reducing reliance on manual operation. The drive device can be a motor, a cylinder, or mechanical components connected to it, etc., and this application does not limit it.

It is understood that the mounting frame 160 may be an integral part of the vehicle body 100, or it may be a separate component fixedly mounted on the upper surface of the vehicle body 100; this application does not impose any limitations on this.

[0037] Reference Figure 3 In some embodiments of the present invention, the height adjustment assembly 300 includes a riser 310 and a lifting rod 320. The riser 310 is fixedly connected to the connecting seat 230 and is arranged along the height direction. The lifting rod 320 is inserted into the riser 310 and is movable relative to the riser 310 along the height direction. The cleaning assembly 400 is rotatably connected to the end of the lifting rod 320 away from the connecting seat 230. The lifting rod 320 is connected to a driving device, which drives the lifting rod 320 to move relative to the riser 310 along the height direction, so that the height adjustment assembly 300 can drive the cleaning assembly 400 to move along the height direction, thereby allowing the cleaning assembly 400 to adjust its relative position with the photovoltaic panel along the height direction. By inserting the lifting rod 320 into the riser 310, the stability of the lifting rod 320's movement along the height direction is improved.

[0038] Reference Figure 3 It is understood that, in some embodiments of the present invention, the driving device connected to the lifting rod 320 includes a lead screw 330, a bevel gear 340 meshing with the lead screw 330, and a first drive motor 350, the output end of the first drive motor 350 being connected to the bevel gear 340.

The first drive motor 350 drives the bevel gear 340 to rotate, thereby causing the lead screw 330 to rotate, which in turn causes the lifting rod 320 to move along the height direction, thereby causing the lifting rod 320 to move along the height direction.

[0039] It is understood that the first drive motor 350 may also be other conventional drive devices and mechanical components connected thereto, in order to drive the lifting rod 320 to adjust its position relative to the riser 310, which is not limited here.

One end of the swing arm 410 is rotatably connected to a height adjustment assembly 300, allowing the swing arm 410 to adjust its angle relative to a horizontal plane. The swing arm 410 can rotate relative to the height adjustment assembly 300 about a first direction or a second direction, allowing the swing arm 410 to adjust its angle relative to the height adjustment assembly 300. An extension 321 is provided at the end of the lifting rod 320 away from the connecting seat 230. The extension 321 extends outward from the outer peripheral wall of the lifting rod 320, and one end of the swing arm 410 is rotatably connected to the extension 321. The swing arm 410 is connected to a drive device for rotating the swing arm 410, enabling the drive device to adjust the angle of the swing arm 410 relative to the photovoltaic panel. This allows the cleaning assembly to adjust its angle relative to the photovoltaic panel, enabling the cleaning assembly to conform to photovoltaic panels at different angles, thus improving the applicability of a photovoltaic panel cleaning device.

[0041] Reference Figure 4 In some embodiments of the present invention, the driving device connected to the rocker arm 410 includes a worm 500, a worm wheel 510, and a second drive motor 520. The worm wheel 510 is connected to the rocker arm 410, and the second drive motor 520 is mounted on the lifting rod 320. The worm 500 is connected to the output end of the second drive motor 520, and the worm 500 meshes with the worm wheel 510. The second drive motor 520 drives the worm 500 to rotate, which in turn drives the worm wheel 510 to rotate, thereby driving the rocker arm 410 to rotate relative to the lifting rod 320, thereby adjusting the angle of the rocker arm 410 relative to the lifting rod 320.

[0042] It is understood that in some embodiments of the present invention, the second drive motor 520 may also be other conventional drive devices and mechanical components connected thereto, so as to drive the swing arm 410 to adjust the angle relative to the lifting arm 320. This application does not limit this.

[0043] Reference Figure 5 In some embodiments of the present invention, the cleaning strip 450 is connected to the outer peripheral wall of the cleaning roller 420, and the cleaning roller 420 is rotatably connected to the swing arm 410, so that the cleaning roller 420 can rotate around the central axis of the cleaning roller 420, thereby driving the cleaning strip 450 to rotate, so that the cleaning strip 450 can rotate to clean the surface of the photovoltaic panel.

[0044] Reference Figure 5 and Figure 6In some embodiments of the present invention, one end of the cleaning roller 420 is provided with a connecting part 423, and the end of the swing rod 410 away from the lifting rod 320 is provided with a connecting hole. The connecting part 423 is inserted into the connecting hole and is rotatably connected to the swing rod 410, so that the cleaning roller 420 can rotate around the axial direction of the cleaning roller 420, thereby driving the cleaning strip 450 to rotate.

[0045] It is understood that a bearing is provided between the connecting part 423 and the inner wall of the connecting hole to realize the rotatable connection of the connecting part 423 to the rocker arm 410. Other common rotatable connection methods can also be used, which are not limited here.

[0046] Reference Figure 5 In some embodiments of the present invention, the cleaning roller 420 is connected to a drive device that drives the cleaning roller 420 to rotate. The drive device connected to the cleaning roller 420 includes a first gear 530, a second gear 540, and a third drive motor 550. The first gear 530 is sleeved on the outer peripheral wall of the cleaning roller 420 and is fixedly connected to the cleaning roller 420. The second gear 540 is connected to the output end of the third drive motor 550, which is mounted on the swing arm 410. The first gear 530 meshes with the second gear 540. The third drive motor 550 drives the second gear 540 to rotate, thereby driving the first gear 530 to rotate, and in turn driving the cleaning roller 420 to rotate. This enables the third drive motor 550 to drive the cleaning roller 420 and the cleaning strip 450 to rotate and clean the photovoltaic panel, improving the cleaning efficiency of the photovoltaic panel and reducing reliance on manual labor.

[0047] It is understood that in some embodiments of the present invention, the third drive motor 550 may also be other conventional drive devices and mechanical components connected thereto, in order to drive the cleaning roller 420 to rotate, and this application does not limit it.

[0048] Reference Figure 6In some embodiments of the present invention, the cleaning roller 420 is provided with a water inlet 421, a cleaning channel, and a water outlet 422 connected in sequence. The water inlet 421 and the water outlet 422 are connected to the outer peripheral wall of the cleaning roller 420, and the two ends of the cleaning channel are respectively connected to the water inlet 421 and the water outlet 422. The water inlet 421 is located at the end of the cleaning roller 420 near the swing arm 410, and the water outlet 422 is located at the part of the cleaning roller 420 where the cleaning strips 450 are provided. The water inlet 421 is used to input cleaning liquid, which can enter the cleaning channel through the water inlet 421 and then flow out through the water outlet 422. At least two sets of cleaning strips 450 are provided, and the at least two sets of cleaning strips 450 are arranged at intervals along the circumference of the cleaning roller 420 to improve the cleaning efficiency and cleaning effect of the cleaning strips 450 on the photovoltaic panels. The water outlet 422 is located between at least two adjacent cleaning strips 450 to ensure that the cleaning strips 450 are in contact with the cleaning liquid. When the cleaning roller 420 drives the cleaning strip 450 to rotate, the cleaning liquid flows out through the water outlet 422. The cleaning strip 450 works with the cleaning liquid to clean the surface of the photovoltaic panel, ensuring the cleaning effect of the photovoltaic panel.

[0049] Reference Figure 3 and Figure 6 In some embodiments of the present invention, at least two water outlet holes 422 are provided, and the at least two water outlet holes 422 are respectively connected to the cleaning flow channel. The at least two water outlet holes 422 are respectively arranged in an array along the circumferential and axial directions of the cleaning roller 420. The water outlet holes 422 distributed along the axial direction of the cleaning roller 420 are located between two sets of cleaning strips 450, which improves the uniformity of the cleaning liquid contacted by the at least two sets of cleaning strips 450 respectively, and ensures the cleaning effect of the photovoltaic panel.

[0050] It is understandable that the extension direction of the water outlet 422 is inclined relative to the cross-section of the cleaning roller, so that the rotation of the cleaning roller 420 can drive the cleaning liquid in the water outlet 422 to be sprayed out at a predetermined angle, thereby increasing the contact range between the cleaning liquid and the photovoltaic panel and thus improving the cleaning effect of the photovoltaic panel.

[0051] It is understood that, in some embodiments of the present invention, the cleaning strip 450 is detachably connected to the outer peripheral wall of the cleaning roller 420, so that the cleaning strip 450 can be replaced individually, thereby improving the service life of the photovoltaic panel cleaning device of the present application.

[0052] It is easy to understand that the cleaning strip 450 can be a rubber scraper or a sponge strip. The specific material of the cleaning strip 450 can be selected according to the actual application, and this application does not limit it.

[0053] Reference Figure 6In some embodiments of the present invention, the cleaning assembly 400 further includes a collar 440, which is rotatably connected to the outer peripheral wall of the cleaning roller 420. The collar 440 has a receiving cavity 441, which surrounds the water inlet hole 421 and is connected to it. The collar 440 is connected to an inlet pipe 442 for inputting cleaning fluid. The cleaning fluid enters the receiving cavity 441 through the inlet pipe 442 and then enters the cleaning channel through the water inlet hole 421. Because the collar 440 is rotatably and sealingly connected to the outer peripheral wall of the cleaning roller 420, when the cleaning roller 420 rotates, the collar 440 and the inlet pipe 442 do not rotate with the cleaning roller 420, ensuring stable input of cleaning fluid through the inlet pipe 442.

[0054] It is understood that in some embodiments of the present invention, a sealing ring is provided between the collar 440 and the cleaning roller 420, so that the collar 440 is rotatably connected to the cleaning roller 420 while ensuring the sealing of the collar 440.

[0055] Reference Figure 6 In some embodiments of the present invention, the outer peripheral wall of the cleaning roller 420 is provided with two sets of limiting rings 424, which are arranged at intervals along the axial direction of the cleaning roller 420, and the water inlet is located between the two sets of limiting rings 424. A collar 440 is sleeved on the outer peripheral wall of the cleaning roller 420, and the limiting rings 424 extend from the outer peripheral wall of the cleaning roller 420 away from the central axis of the cleaning roller 420. The collar 440 is rotatably connected to the limiting rings 424, and the limiting rings 424 are connected to the inner wall of the receiving cavity 441. The positioning of the collar 440 connected to the cleaning roller 420 is achieved by the limiting rings 424 connected to the collar 440, which facilitates the connection of the collar 440 to the cleaning roller 420.

[0056] It is understood that in some embodiments of the present invention, a sealing ring is provided between the collar 440 and the limiting ring 424 to improve the sealing performance of the collar 440 and reduce the risk of cleaning fluid leakage between the collar 440 and the limiting ring 424. By extending the limiting ring 424 from the outer peripheral wall of the cleaning roller 420 in a direction away from the central axis of the cleaning roller 420, the cleaning roller 420 and the limiting ring 424 are rotatably connected, increasing the area of ​​the connection portion 423 between the collar 440 and the cleaning roller 420, and improving the connection stability between the collar 440 and the cleaning roller 420.

[0057] Reference Figure 1In some embodiments of the present invention, the photovoltaic panel cleaning device proposed in this application further includes a carrier tank 120 for loading cleaning fluid. The carrier tank 120 is located on the vehicle body 100, and the carrier tank 120 is connected to the receiving cavity 441 via a water pipe 150. One end of the water pipe 150 is connected to the carrier tank 120, and the other end is connected to the liquid inlet pipe 442. The carrier tank 120 can provide clean water for cleaning the photovoltaic panels, enabling the photovoltaic panel cleaning device proposed in this application to be used in environments where it is inconvenient to provide clean water, such as outdoors, thus improving the applicability of the photovoltaic panel cleaning device.

[0058] Understandably, the carrier box 120 is equipped with a pump body, which can pump the cleaning liquid in the carrier box 120 to the receiving cavity 441, so that the liquid in the carrier box 120 can be supplied to clean the photovoltaic panels.

[0059] It is understood that the photovoltaic panel cleaning device proposed in this application also includes a mobile power supply. The mobile power supply is installed on the vehicle body 100 and is used to power the water pump, drive device and other electrical equipment of the cleaning device, so as to ensure the power supply of the cleaning device in outdoor environments and make the cleaning device suitable for outdoor environments.

[0060] It is understood that after use, the photovoltaic panel cleaning device proposed in this application allows for the following adjustments: The horizontal adjustment component 200 is adjusted so that the connecting seat 230 moves towards the vehicle body 100, enabling the cleaning component 400 to retract horizontally towards the vehicle body 100; the height adjustment component 300 is adjusted so that the cleaning component 400 descends towards the vehicle body 100 along the height direction; and the angle of the swing arm 410 relative to the height adjustment component 300 is adjusted so that the cleaning component 400 fits against the height adjustment component 300. This allows the photovoltaic panel cleaning device to be stored towards the vehicle body 100, reducing its size and space occupation. The rollers 130 on the vehicle body 100 facilitate the transfer of the photovoltaic panel cleaning device.

[0061] In summary, this application proposes a cleaning device for photovoltaic panels, comprising: a vehicle body 100, a leveling component 200, a height adjusting component 300, and a cleaning component 400. The leveling component 200 is mounted on the upper surface of the vehicle body 100 and includes a connecting seat 230, at least two adjusting seats 210, and at least two connecting rods 220. The two ends of the connecting rods 220 are rotatably connected to the adjusting seats 210 and the connecting seat 230, respectively. The at least two adjusting seats 210 are spaced apart along a first direction. The ends of the two connecting rods 220 are rotatably connected to the connecting seats 230, and the other ends of the two connecting rods 220 are rotatably connected to the two adjusting seats 210, respectively. The height adjusting component 300 is connected to the connecting seat 230, and the cleaning component 400 is connected to the height adjusting component 300. When the two adjusting seats 210 approach each other along the first direction, they cause the two connecting rods 220 connected to them to move, which in turn causes the connecting seat 230 to move away from the vehicle body 100 along the second direction, causing the cleaning component 400 corresponding to the connecting seat 230 to move away from the vehicle body 100. By the two adjusting seats 210 approaching and moving away from each other along the first direction, the position of the cleaning component 400 relative to the photovoltaic panel along the second direction can be adjusted. By moving the cleaning component 400 along the height direction through the height adjusting component 300, the position of the cleaning component 400 relative to the photovoltaic panel along the height direction can be adjusted. By adjusting the angle of the cleaning component 400 relative to the horizontal plane, the angle of the cleaning component 400 relative to the photovoltaic panel can be adjusted.

[0062] When the photovoltaic panel cleaning device proposed in this application is used, the vehicle body 100 is moved to the corresponding position of the photovoltaic panel. The horizontal adjustment component 200, the height adjustment component 300, and the cleaning component 400 rotate relative to the height adjustment component 300 in coordination, adjusting the cleaning component 400 to adhere to the photovoltaic panel. The movement of the vehicle body 100 relative to the photovoltaic panel causes the cleaning component 400 to adhere to and clean the photovoltaic panel, thereby achieving cleaning. Because the horizontal adjustment component 200 and the height adjustment component 300 cooperate with the rotation of the cleaning component 400 relative to the height adjustment component 300, the position of the cleaning component 400 relative to the photovoltaic panel can be easily adjusted, making it suitable for photovoltaic panels in different installation positions, facilitating operation, and improving cleaning efficiency.
