Description

Technical Field

[0001] The present disclosure relates to the technical field of solar panels, and in particular to a solar panel cleaning device. Background Art

[0002] In related technologies, since solar panels are placed outdoors for a long time, dust, fallen leaves, and even plastic bags and other debris will inevitably accumulate on the panel surface. If they are not cleaned, dust and other debris will cause reduced light transmittance or partial obstruction, which will at the very least affect the power generation efficiency of the solar panels, and at worst cause local overheating or even burn the solar panel components.

[0003] On-board track cleaning involves pre-installing tracks on solar panels, on which a reciprocating cleaning machine is placed to clean the surface of the solar panels. However, this requires installing tracks on the solar panels, which results in high initial investment costs. Furthermore, the tracks are prone to sand jams, which reduces the reliability of the reciprocating movement of the cleaning machine and increases subsequent maintenance costs. Furthermore, the cleaning machine may scratch the surface of the solar panels as it moves on the tracks, affecting the service life of the solar panels and the photovoltaic conversion efficiency. Utility Model Content

[0037] See also Figure 1 The present disclosure provides a solar panel cleaning device, including a mounting base 10 and two auxiliary support bases 20. The two ends of the mounting base 10 are respectively provided with first rollers 11, and the mounting base 10 reciprocates along the length direction or width direction of the solar panel 1 through the first rollers 11. The mounting base 10 is provided with a cleaning mechanism for cleaning the upper surface of the solar panel 1; the two auxiliary support bases 20 are respectively detachably connected to the two ends of the mounting base 10, and the two auxiliary support bases 20 are provided with second rollers 21, which are configured to be able to roll in contact with the side edge of the solar panel 1 when the auxiliary support base 20 is connected to the end of the mounting base 10.

[0038] In the present disclosure, the cleaning mechanism can clean the upper surface of the entire solar panel 1 when the mounting base 10 moves back and forth along the length or width direction of the solar panel 1, thereby avoiding the problem of reduced light transmittance or partial obstruction caused by dust and other debris deposited on the solar panel 1.

[0039] According to the technical solution provided by the present disclosure, auxiliary support bases 20 are detachably connected to both ends of the mounting base 10. Second rollers 21 are provided on the auxiliary support bases 20 to enable rolling contact with the side edges of the solar panel 1. The first rollers 11 provided at both ends of the mounting base 10 cooperate with the second rollers 21 on the auxiliary support base 20 to ensure the stability of the mounting base 10 during reciprocating movement on the upper surface of the solar panel 1. The technical solution provided by the present disclosure effectively solves the problems of high initial investment costs and poor reliability during subsequent use caused by the existing technology of adding tracks to the solar panel 1.

[0040] It should be noted that since the solar panel cleaning device provided by the present invention needs to be assembled on the solar panel 1 before the cleaning work, it is preferred that the mounting base 10 has a smaller span to reduce the longitudinal dimension of the mounting base 10, that is, the mounting base 10 spans the width direction of the solar panel 1. After the assembly is completed, the mounting base 10 can move back and forth along the longitudinal direction of the solar panel 1.

[0041] In some embodiments, to further improve the operational stability of the solar panel cleaning device, two second rollers 21 are provided, and the two second rollers 21 are spaced apart along the moving direction of the auxiliary support base 20. When the auxiliary support base 20 is assembled to the end of the mounting base 10, the two second rollers 21 on the auxiliary support base 20 can both roll in contact with the side edges of the solar panel 1, thereby ensuring stability during operation.

[0042] See also Figure 3 In some embodiments, the auxiliary support base 20 is further provided with a third roller 22. The third roller 22 is configured to roll in contact with the lower surface of the solar panel 1 when the auxiliary support base 20 is connected to the end of the mounting base 10. It will be appreciated that the provision of the third roller 22 in rolling contact with the lower surface of the solar panel 1 further improves the stability of the solar panel cleaning device during operation, preventing it from tipping over or tilting, and avoiding scratches on the upper surface of the solar panel 1.

[0043] It is understood that in the present disclosure, the auxiliary support seat 20 can adopt any appropriate structural form, as long as the second roller 21 and the third roller 22 can be set at appropriate positions. Figure 3 As shown, the auxiliary support seat 20 includes a first support plate 23, a second support plate 24 and a connecting plate 25. The first support plate 23 and the second support plate 24 are parallel and spaced apart and are connected and fixed by the connecting plate 25. The end of the first support plate 23 close to the solar panel 1 is detachably connected to the end of the mounting seat 10. The side of the connecting plate 25 close to the solar panel 1 is used to install the second roller 21, and the side of the second support plate 24 close to the solar panel 1 is used to install the third roller 22.

[0044] In some embodiments, a plug-in portion 26 is provided at the end of the first support plate 23 close to the solar panel 1 , and a plug-in interface 12 is provided at the end of the mounting base 10 . The plug-in portion 26 is detachably plugged into the plug-in interface 12 .

[0045] More specifically, combined Figure 2 As shown, the plug-in portion 26 is provided with a telescopic spring pin 261. When the plug-in portion 26 is inserted into the plug-in interface 12, the telescopic spring pin 261 can extend through a limiting hole 121 provided on the mounting base 10 and extending through the plug-in interface 12, thereby achieving a limited fit. When disassembly is required, the telescopic spring pin 261 is pressed to disengage the plug-in portion 26 from the plug-in interface 12.

[0046] In the present disclosure, the mounting base 10 can be driven by any appropriate means to reciprocate along the length direction or width direction of the solar panel 1 through the first roller 11. In some embodiments, the mounting base 10 can be driven by any appropriate means to reciprocate along the length direction or width direction of the solar panel 1 through the first roller 11. Figure 1 、 Figure 3and Figure 4 As shown, a drive motor 13 and a battery pack 14 for providing electrical energy to the drive motor 13 are provided on the mounting base 10. The drive motor 13 is transmission-connected to the first roller 11 and can drive the first roller 11 to roll back and forth along the length direction or width direction of the solar panel 1.

[0047] It is understandable that, in order to balance the weight, the battery packs 14 can be placed separately, that is, two battery packs 14 are provided, and the two battery packs 14 are symmetrically arranged on the upper surface of the mounting base 10 .

[0048] In some embodiments, in order to improve the stability of the device, two first rollers 11 are provided at one end of the mounting base 10 , and the two first rollers 11 are spaced apart along the moving direction of the mounting base 10 .

[0049] It should be noted that in the present disclosure, the mounting base 10 needs to be assembled with two auxiliary support bases 20 before the upper surface of the solar panel 1 can be cleaned. By setting two first rollers 11 at one end of the mounting base 10, the mounting base 10 can be placed on the upper surface of the solar panel 1 through the four first rollers 11, and then the auxiliary support base 20 can be assembled onto the mounting base 10. That is, the above structural setting facilitates the assembly of the cleaning device.

[0050] In the present disclosure, the cleaning mechanism may adopt any appropriate structural form, as long as it is capable of cleaning dust and other debris from the upper surface of the solar panel 1 when the mounting base 10 reciprocates along the length or width of the solar panel 1. In some embodiments, the cleaning mechanism includes a liquid storage tank 30, a nozzle 31, and a cleaning cloth 32. The liquid storage tank 30 is disposed on the side of the mounting base 10 facing away from the solar panel 1 and is capable of storing cleaning liquid; the nozzle 31 is disposed on the mounting base 10 and is configured to spray the cleaning liquid in the liquid storage tank 30 onto the upper surface of the solar panel 1; and the cleaning cloth 32 is fixed to the side of the mounting base 10 near the solar panel 1 and extends along the length of the mounting base 10.

[0051] In the technical solution provided by the present disclosure, the cleaning cloth 32 for cleaning the upper surface of the solar panel 1 is fixed to the side of the mounting base 10 close to the solar panel 1 by a fixing member, such as a bolt or a screw. During the movement of the mounting base 10, the cleaning cloth 32 can wipe the solar panel 1 and clean the dust and other debris deposited on the solar panel 1. Therefore, after the fixing member fixes the cleaning cloth 32, the distance between the fixing member and the upper surface of the solar panel 1 is very close. In order to avoid the fixing member from scratching the solar panel 1, in some embodiments, such as Figure 4 As shown, the cleaning mechanism further includes a protective cloth 33 , which is used to cover the fixing piece of the cleaning cloth 32 . Both ends of the protective cloth 33 extend and are fixed to the upper surface of the mounting base 10 .

[0052] More specifically, in some embodiments, Figure 5 As shown, the protective cloth 33 is extended along the length direction of the mounting base 10 , and through holes 15 are respectively provided at both ends of the mounting base 10 for the two ends of the protective cloth 33 to pass through and extend to the upper surface of the mounting base 10 .

[0053] Alternatively, in some embodiments, Figure 6 As shown, the protective cloth 33 is extended along the width direction of the mounting base 10 , and both ends of the protective cloth 33 can be directly extended and fixed to the upper surface of the mounting base 10 .

[0054] In some embodiments, a plurality of nozzles 31 are provided, and the plurality of nozzles 31 are spaced apart along the length direction of the mounting base 10 and form a nozzle group; a nozzle group is provided on the mounting base 10 on one or both sides of the cleaning cloth 32. It is understood that the nozzle 31 is connected to the liquid storage tank 30 and can spray the cleaning liquid in the liquid storage tank 30 onto the upper surface of the solar panel 1. By providing the nozzle groups on both sides of the cleaning cloth 32, the solar panel 1 can be sprayed with the cleaning liquid when the cleaning cloth 32 wipes back and forth; in addition, the nozzle groups on both sides of the cleaning cloth 32 can also be turned on as needed according to cleaning needs. For example, in the later stage of cleaning, it is only necessary to wipe the water stains on the upper surface of the solar panel 1 by wiping back and forth with the cleaning cloth 32. At this time, it is not necessary to continue spraying the cleaning liquid on the upper surface of the solar panel 1. Therefore, the nozzle 31 can be controlled to stop spraying the cleaning liquid on the upper surface of the solar panel 1.

[0055] According to the solar panel cleaning device provided by the present disclosure, the moving stroke and operating speed of the mounting base 10 can be controlled in a pre-set manner. Alternatively, a microprocessor and a wireless communication module connected to the microprocessor are provided on the mounting base 10. The wireless communication module is connected to a cloud server, and the cloud server is connected to a mobile terminal. The operator can use the mobile terminal to set the moving stroke and operating speed of the mounting base 10 in real time, thereby meeting the cleaning requirements of solar panels 1 of different specifications or different degrees of dirtiness. Accordingly, a detection device can also be provided in the liquid storage tank 30 of the cleaning mechanism to detect the amount of cleaning liquid, and the amount of cleaning liquid is fed back to the mobile terminal through the wireless communication module so that the operator can grasp the amount of cleaning liquid in a timely manner.

[0056] The solar panel cleaning device provided by the present invention has a simple structure and is easy to use. It solves the problem that the existing track cleaning on the panel requires the pre-installation of tracks, resulting in high initial investment costs and poor reliability in subsequent use; the solar panel cleaning device is easy to assemble and disassemble, can be easily assembled to multiple solar panels for cleaning operations, and has low cost of use.

Based on the above description, those skilled in the art can fully understand how to implement the technical solutions disclosed herein.

Those skilled in the art will understand that the above embodiments may be modified or some technical features may be replaced with equivalents without departing from the scope and spirit of the present disclosure.
