Description

Technical Field

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

[0002] Photovoltaic systems are now built in many places. The photovoltaic panels of the photovoltaic systems need to be cleaned at regular intervals. Patent announcement document CN201444479U discloses a structure that can clean photovoltaic panels.

With the help of the track and the pulley, the end assembly can move on the photovoltaic panel. Therefore, this device can move on the photovoltaic panel through its own pulley and track itself, without the help of tracks, so the operation is more convenient and there is no need to increase the volume of the entire photovoltaic system.

[0007] Specifically in the present device, the roller brush is used to contact the photovoltaic panel, and when the roller brush rotates, the photovoltaic panel is cleaned.

[0008] Optionally, an ultrasonic sensor assembly is also included, and the ultrasonic sensor assembly is arranged on the end seat.

[0011] The specific side guide wheels are not coordinated with the motor, and there is no driving power to drive the side guide wheels to rotate. The side guide wheels are used to contact the edges of the photovoltaic panels. In this way, when the entire device deviates from the photovoltaic panel, the side guide wheels on the two end seats can guide and correct the deviation, thereby completing the anti-jamming and deviation correction of the machine at a certain angle.

[0012] Optionally, a disc brush is also included, and the disc brush is arranged on the end seat.

[0013] Specifically, a cleaning motor for driving a disc brush to rotate is arranged on the end seat, and the cleaning motor drives the disc brush to rotate, and during the rotation of the disc brush, the traces left by the track on the photovoltaic panel can be cleaned. Specifically, two disc brushes are arranged on each end seat, and the track is located between the two disc brushes.

[0014] Optionally, it also includes a connecting rod, the two ends of which are respectively matched with the end seats, the connecting rod is located in the connecting shell, and the connecting rod is rotatably provided with auxiliary wheels, and the auxiliary wheels are close to the roller brush.

[0015] The connecting rod is used to install the auxiliary wheel, and the connecting rod can improve the stability of the end seat and the connecting shell. The connecting shell is provided with a buckle, and the connecting rod is clamped in the buckle.

[0016] Optionally, there are two connecting rods, the two connecting rods are in parallel, and the roller brush is located between the two parallel connecting rods.

[0017] Optionally, a rotating motor and a traveling motor are arranged in the end seat, the rotating motor cooperates with the rotating joint, and the traveling motor cooperates with the pulley.

[0018] Specifically, the rotating motor drives the roller brush to rotate, and the traveling motor drives the pulley to rotate so that the crawler belt runs.

[0019] The beneficial effects of the utility model are as follows: the photovoltaic panel can be moved by the self-contained wheels and the crawler itself, without the need for tracks, so the operation is more convenient and the volume of the entire photovoltaic system does not need to be increased.
