The technical scheme of the utility model is further described below by the specific embodiments with reference to the accompanying drawings.
As shown in fig. 1 and fig. 2, fig. 1 is an overall schematic view of a photovoltaic cleaning robot provided by an embodiment of the present utility model, and fig. 2 is a partial schematic view of the photovoltaic cleaning robot provided by the embodiment of the present utility model;
Example 1
The paraxial photovoltaic cleaning assembly provided by the embodiment is applied to a scene of dust cleaning on a photovoltaic panel, and the structure of the paraxial photovoltaic cleaning assembly is improved, so that the paraxial photovoltaic cleaning assembly can be more stably adjusted to be in a posture, and further the paraxial photovoltaic cleaning assembly is prevented from being blocked by the photovoltaic panel.
As shown in fig. 1 and 2, the off-axis photovoltaic cleaning module in the present embodiment includes a roller brush module 10, a driving motor module 20, a first driving shaft 30, and a second driving shaft 40; the first driving shaft 30 and the second driving shaft 40 can be driven by the driving motor assembly 20 to rotate independently, that is, the driving motor assembly 20 is at least provided with a first motor (not shown) and a second motor (not shown), the first motor can independently drive the first driving shaft 30 to rotate, and the second motor can independently drive the second driving shaft 40 to rotate; the first driving shaft 30 and the second driving shaft 40 are arranged at intervals and extend along the first direction; the first driving shaft 30 is fixedly connected with a first traveling wheel 31 and a second traveling wheel 32 at intervals, and the second driving shaft 40 is fixedly connected with a third traveling wheel 41 and a fourth traveling wheel 42 at intervals.
Wherein the first travelling wheel 31 and the third travelling wheel 41 are arranged at intervals along a direction perpendicular to the first direction; in the first direction, the first road wheel 31 and the third road wheel 41 are both located between the second road wheel 32 and the fourth road wheel 42; illustratively, the first road wheel 31 is centered on the first drive shaft 30, the second road wheel 32 is located above the first road wheel 31, the third road wheel 41 is centered on the second drive shaft 40, and the fourth road wheel 42 is located below the third road wheel 41.
Specifically, the off-axis photovoltaic cleaning assembly in the embodiment can drive the first driving shaft 30 and the second driving shaft 40 to rotate independently through the driving motor assembly 20, and the travelling wheels are arranged on the two driving shafts independently, so that the difference of rolling distances between the travelling wheels can be compensated through setting the speed difference between the first driving shaft 30 and the second driving shaft 40, the angle of the off-axis photovoltaic cleaning assembly relative to the photovoltaic panel can be corrected in time, and the risk of blocking of the off-axis photovoltaic cleaning assembly can be eliminated; for example, when the second traveling wheel 32 above is idling, the upper side of the off-axis photovoltaic cleaning module will be to the left and the lower side of the off-axis photovoltaic cleaning module will be to the right, i.e., offset in angle relative to the photovoltaic panel; subsequently, the difference in rolling distance between the road wheels can be compensated for by increasing the rotational speed of the first drive shaft 30.
Meanwhile, the travelling wheels are distributed on the driving shafts in a Z shape, namely, for any driving shaft, the travelling wheels roll on the photovoltaic panel at least through two travelling wheels, when the two driving shafts run at a differential speed, the different-axis photovoltaic cleaning assembly has angle change, and for the second travelling wheel 32 and the fourth travelling wheel 42 which are positioned on the outer side, larger traction force is required to be provided for enabling the different-axis photovoltaic cleaning assembly to deflect, at the moment, the first travelling wheel 31 can balance the load of the first driving shaft 30, the risk that the second travelling wheel 32 slides along the first driving shaft 30 is reduced, the third travelling wheel 41 can balance the load of the second driving shaft 40, the risk that the fourth travelling wheel 42 slides along the second driving shaft 40 is reduced, and the different-axis photovoltaic cleaning assembly and the photovoltaic cleaning robot can control the self-posture stably. For example, when the rotational speed of the first driving shaft 30 is increased to compensate for the difference in rolling distance between the road wheels, the upper second road wheels 32 are subject to the influence of load factors such as centrifugal force and friction force, and a sliding trend of moving downward along the second driving shaft 40 occurs, at this time, by the arrangement of the first road wheels 31, the load can be balanced, and the load of the second road wheels 32 can be reduced, thereby improving the stability.
Further, as shown in fig. 1, the first driving shaft 30 is further rotatably connected to the first supporting wheel 33 on one side of the fourth traveling wheel 42, and the second driving shaft 40 is further rotatably connected to the second supporting wheel 43 on one side of the third traveling wheel 41. The first driving shaft 30 is rotatably connected with a third supporting wheel 34 between the first traveling wheel 31 and the second traveling wheel 32 and between the first traveling wheel 31 and the first supporting wheel 33; a fourth supporting wheel 44 is rotatably connected between the third traveling wheel 41 and the fourth traveling wheel 42 and between the third traveling wheel 41 and the second supporting wheel 43 by the second driving shaft 40. It can be appreciated that radial support can be added to the driving shaft through the supporting wheels, and the central part of the driving shaft can be prevented from sinking for the driving shaft with a longer length, so that the stability of the off-axis photovoltaic cleaning assembly is improved.
In the present embodiment, the roller brush assembly 10 includes a roller brush motor (not shown), and a motor shaft of the roller brush motor is fixedly connected with a plurality of roller brush units 11.
In the present embodiment, the first drive shaft 30 and the second drive shaft 40 are located between any two of the roller brush units 11 in a direction perpendicular to the first direction. As a preferred embodiment, the number of the roller brush units 11 is two, and the first driving shaft 30 and the second driving shaft 40 are located between the two roller brush units 11. The roller brush unit 11 is arranged at the outermost side, so that the abnormal axis photovoltaic cleaning assembly can be ensured to completely clean the photovoltaic panel, and the cleaning efficiency is improved.
In the present embodiment, the roller brush motor is located at one side of the first driving shaft 30, and the driving motor assembly 20 is located at the other side of the first driving shaft 30, so that the structure is more compact.

The photovoltaic cleaning robot provided in the present embodiment includes a suspension portion 50, and the off-axis photovoltaic cleaning assembly as in the first embodiment is mounted on the suspension portion 50; a mounting gap for the photovoltaic panel to be clamped in is formed between the hanging part 50 and the off-axis photovoltaic cleaning assembly. For example, when a certain photovoltaic panel needs to be cleaned, the installation gap between the hanging part 50 and the off-axis photovoltaic cleaning component can be sleeved on the upper edge of the photovoltaic panel manually, so that the installation of the photovoltaic cleaning robot is completed; when the photovoltaic panel is cleaned, the photovoltaic cleaning robot moves on the photovoltaic panel along the horizontal direction through the driving wheels, and the cleaning of the photovoltaic panel is completed by matching with the roller brush unit 11. In the first embodiment, a specific structure and technical effects related to the off-axis photovoltaic cleaning module are described, and the photovoltaic cleaning robot in the present embodiment refers to the structure and has the technical effects as well.
