Description

Technical Field

[0001] The invention relates to the field of photovoltaic panel cleaning, in particular to a stopping device of a photovoltaic cleaning machine. Background Art

[0002] Since large photovoltaic power stations are usually built in areas with harsh climates and severe sandstorms, it is easy for dirt, such as dust and bird droppings, to adhere to the photovoltaic panels, affecting the absorption effect of the photovoltaic panels on the solar panels. In addition, dirt attached to the photovoltaic panels will cause hot spot effects. If the photovoltaic panels are not cleaned in time, the power generation of the photovoltaic power station will be greatly reduced, affecting the life of the photovoltaic panels. To solve this problem, photovoltaic cleaning machines have been developed, which can move on the photovoltaic panels to clean them.

[0003] Photovoltaic sweepers can automatically clean photovoltaic panels at night through command control, but they cannot stay on the photovoltaic panels after cleaning, so another parking device is needed for the photovoltaic sweeper to stop. However, the current parking device cannot adjust the angle, and in order to maintain high absorption efficiency, photovoltaic panels will adjust the angle through the tracking system, which sometimes causes the parking device to not be fully aligned with the photovoltaic panel, resulting in the photovoltaic sweeper being unable to move from the parking device to the photovoltaic panel. At this time, manual adjustment is required, or even transportation is required to put the photovoltaic sweeper on the photovoltaic panel. Summary of the invention

[0035] like Figures 1 to 10 As shown, the present invention discloses a stopping device for a photovoltaic sweeper, which includes a supporting assembly 1 and a track assembly 2 for the photovoltaic sweeper C to travel.

[0036] Cooperate Figures 1 to 10 As shown, the support assembly 1 includes a support frame 11 and a support rod 12 and a limit rod 13 obliquely arranged on the support frame 11; the support rod 12 and the limit rod 13 are inclined downward from back to front, and the limit rod 13 is located on the left side of the support rod 12 and is lower than the support rod 12.

[0037] Cooperate Figures 1 to 10As shown, the track assembly 2 includes an upper track 21 and a lower track 22; the upper track 21 is rotatably connected to the rear end of the support rod 12, and the lower track 22 is rotatably connected to the front end of the support rod 12, the upper track 21 and the lower track 22 rotate independently, and the rotation center of the upper track 21 and the rotation center of the lower track 22 are on the same rotation axis, and the rotation axis is arranged parallel to the support rod 12, the center of gravity of the upper track 21 is on the right side of the rotation center of the upper track 21, and the center of gravity of the lower track 22 is on the right side of the rotation center of the lower track 22; the left sides of the upper track 21 and the lower track 22 movably abut against the upper surface of the limit rod 13; when the left side of the upper track 21 abuts against the upper surface of the limit rod 13, the right side of the upper track 21 is tilted upward relative to the inclined surface where the support rod 12 is located; when the left side of the lower track 22 abuts against the upper surface of the limit rod 13, the right side of the lower track 22 is tilted upward relative to the inclined surface where the support rod 12 is located.

[0038] Cooperate Figure 4 , Figure 5 , Fig. 9 and Fig.10 As shown, when the present invention is in use, the photovoltaic panel array G is arranged on the right side of the present invention for the upper track 21 and the lower track 22 to abut against; Figure 3 and Figure 8 As shown, when the photovoltaic sweeper C is in the present invention, the running wheels C1 at the front and rear ends of the photovoltaic sweeper C can run on the upper surfaces of the upper track 21 and the lower track 22, while the hanging wheels C2 at the rear side of the photovoltaic sweeper C can run on the side of the upper track 21, and the hanging wheels at the rear side of the photovoltaic sweeper C cooperate with the upper track 21 to prevent the sweeper from falling.

Since the upper track 21 and the lower track 22 rotate independently, for photovoltaic panel arrays G with different inclination angles, the right sides of the upper track 21 and the lower track 22 can be pressed against the photovoltaic panel array G when they rotate downward, so that the photovoltaic cleaning machine C can be moved to the photovoltaic panel array G for cleaning; when the photovoltaic cleaning machine C is completely moved to the photovoltaic panel array G, since the center of gravity of the upper track 21 is on the right side of the rotation center of the upper track 21, and the center of gravity of the lower track 22 is on the right side of the rotation center of the lower track 22, the right sides of the upper track 21 and the lower track 22 can both remain pressed against the photovoltaic panel array G, so that the photovoltaic cleaning machine G can return to the parking device after cleaning is completed.
