The application of photovoltaic cleaning robots can improve photovoltaic power generation efficiency, extend the service life of photovoltaic panels, and reduce maintenance costs. However, due to the gaps between adjacent photovoltaic panels, photovoltaic cleaning robots are easily stuck when moving between adjacent photovoltaic panels; in addition, the unevenness of adjacent photovoltaic panels will also make it impossible for photovoltaic cleaning robots to cross.

[0029] An obstacle-crossing photovoltaic cleaning robot

[0030] like Figure 1 to Figure 3As shown, it includes a frame 1, a brush roller 202 arranged on the frame 1, a brush roller motor (arranged in a control box 201), a travel motor (arranged in a control box 201) arranged on the frame 1, a travel drive wheel 302, a synchronous belt 303, a passive travel wheel 304, a connecting frame 305, and a telescopic spring 306. The brush roller 202 is arranged along the length direction of the frame 1 and connected to the output shaft of the brush roller motor. The control box 201 in which the brush roller motor and the travel motor are arranged is arranged at one end of the frame 1. The brush roller 202 and the brush roller motor driving the brush roller motor to rotate constitute a cleaning mechanism 2. The walking drive wheel 302 is connected to the output shaft of the walking motor, and the central axes of the walking drive wheel 302 and the walking wheel 304 are connected to each other through a connecting frame 305, and the central axis is connected to the connecting frame 305 through a bearing structure, so as to fix the relative position between the walking drive wheel 302 and the walking wheel 304; one end of the telescopic spring 306 is connected to the frame body 1, and the other end is connected to the position above the walking wheel 304 on the connecting frame 305; so that the walking wheel 304 is tilted and higher than the walking drive wheel 302; as a typical embodiment, the walking drive wheel and the walking wheel adopt the same specification of wheel body; the walking motor, the walking drive wheel 302, the synchronous belt 303, the walking wheel 304, the connecting frame 305, and the telescopic spring 306 constitute the walking mechanism 3; the walking mechanism includes at least two sets, which are symmetrically arranged on the front and rear sides of the frame body 1, and the walking drive wheel 302 and the walking wheel 304 are synchronously rotated by the synchronous belt 303. Under the drive of the walking motor, the walking drive wheel 302 drives the walking wheel 304 to rotate through the synchronous belt 303 to realize the movement of the frame body 1.

[0031] The connecting frame comprises side plates located at both sides of the walking wheel and the walking driving wheel and a top plate connecting the two side plates, and the telescopic spring is connected to the top plate of the connecting frame.

[0032] There is one set of walking mechanisms located at the front and rear sides of the frame 1 , and at least two sets of walking mechanisms 3 are arranged side by side on the frame 1 , respectively located at the two ends of the frame 1 .

[0033] As a typical implementation, a plurality of groups of traveling mechanisms 3 are arranged side by side on the frame 1 , and the traveling mechanisms 3 located on the same side of the frame share the same central axis 301 .

[0034] like Figure 4 As shown, the frame 1 is assembled from multiple pieces to accommodate the cleaning of photovoltaic panels of different widths, and adjacent frame pieces are connected by hinge structures.

[0035] The frame 1 is provided with a photovoltaic panel power source 101 to provide power for the brush roller motor and the travel motor.

[0036] The utility model is characterized in that the walking mechanism 3 on the front and rear sides of the frame 1 adopts a two-wheel structure, and a telescopic spring structure connecting the walking mechanism and the frame, such as Figure 3As shown, in a normal state, driven by the front and rear walking drive wheels 302, the photovoltaic cleaning robot walks normally between adjacent photovoltaic panels, and the walking wheels do not touch the photovoltaic panels; when adjacent photovoltaic panels are uneven, especially when the front photovoltaic panel is higher, the walking wheels are upturned and can step over the front photovoltaic panel, thereby driving the rear walking drive wheels to continue to move forward, and the telescopic spring 306 is appropriately compressed to achieve a shock-absorbing effect, thereby ensuring the smooth movement of the photovoltaic cleaning robot; when the gap between adjacent photovoltaic panels is large, the walking wheels first cross the gap, and the friction with the front photovoltaic panel provides forward force for the rear walking drive wheels, and when the walking drive wheel 302 is stuck in the gap, the walking wheel 304 on the same side of the same connecting frame can pull the walking drive wheel 302 out, thereby achieving crossing in a large gap scenario.

[0037] It should be explained that the size of the gap between adjacent photovoltaic panels is due to errors during installation, so it will not be particularly large, and a conventional single-wheel structure may get stuck; the structure designed in this structure that connects the walking wheel and the walking drive wheel through a connecting frame can meet the needs of spanning the gaps between most photovoltaic panels.

[0038] Compared with the traditional single-wheel structure, it can move under various road conditions, avoiding the situation where the photovoltaic panels are uneven and the gaps are too large to cross and cause getting stuck.

[0039] As a further improvement to the structure, bristles are arranged on the periphery of the brush roller 202 to clean the photovoltaic panels.

[0040] As a typical embodiment, the lower end of the brush roller is 10-20 mm lower than the lower end of the walking wheel or the walking drive wheel, and the bristles are soft and will not affect walking, while achieving a cleaning effect on the photovoltaic panel.

[0041] The brush roller 202 is connected to a compressed air source, and an air vent is provided on the outer wall of the brush roller to blow and clean the photovoltaic panel.

[0042] As another embodiment, the brush roller 202 is connected to a water source, and a water hole is provided on the outer wall of the brush roller to supply water to clean the photovoltaic panel.

[0043] The connecting frame comprises side plates located at both sides of the walking wheel and the walking driving wheel and a top plate connecting the two side plates, and the telescopic spring is connected to the top plate of the connecting frame.

[0044] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
