Description

Technical Field

[0001] The utility model relates to the technical field of cleaning robots, and more specifically to a device for automatically adjusting the height of a roller brush. Background Art

[0002] With the continuous development of the photovoltaic industry, problems in the operation and management of photovoltaic power stations have gradually emerged, especially the problem of surface cleaning of photovoltaic panels, which is the key to the power generation efficiency of photovoltaic power stations. Photovoltaic panels are set outdoors, and the accumulation of dust, bird droppings, fallen leaves, pollen, etc. on the surface of photovoltaic panels will form dirt, which will seriously affect the power generation efficiency of photovoltaic power stations. Therefore, it is urgent to effectively clean photovoltaic panels.

[0003] There are various forms of existing photovoltaic panel arrangements. Photovoltaic power stations generally use photovoltaic modules of the same specifications for large-scale arrangements. On the one hand, due to terrain reasons and human assembly errors, there are uneven arrangements, misalignments, and height differences between two adjacent groups of photovoltaic modules. On the other hand, the roller brush is prone to wear, shortening and softening after a long period of operation. The temperature difference between spring and winter causes deformation of the surface of the photovoltaic panel, which requires cleaning equipment to clean surfaces at different heights. For traditional cleaning robots, since the roller brush is fixed on the surface of the frame, the distance between the roller brush and the ground is fixed, which makes it impossible for the roller brush to contact the photovoltaic panel with appropriate force for cleaning, resulting in low cleanliness when cleaning the photovoltaic panel.

[0004] Therefore, it is necessary to provide a device for automatically adjusting the height of a roller brush, which can automatically adjust the height according to the cleaning surface to ensure that the roller brush contacts the surface to be cleaned to improve its cleaning effect. Utility Model Content

[0005] The utility model provides a device for automatically adjusting the height of a roller brush, so as to solve the problem that the existing photovoltaic cleaning robot cannot automatically adjust the height of the roller brush according to the height of the ground, resulting in poor cleaning effect.

[0006] According to one aspect of the utility model, a device for automatically adjusting the height of a roller brush is provided, which is used to adjust the roller brush of a photovoltaic panel cleaning robot. The device includes a mounting plate, a mounting shaft and a roller brush bearing bracket. A long hole is installed on the mounting plate. The roller brush bearing bracket includes a connecting head and two clamping plates. The two clamping plates are connected by the connecting head, and the clamping plates are clamped on both sides of the long hole. The two ends of the mounting shaft are connected to the roller brush bearing bracket, and one of the roller brush bearing brackets is connected to the output end of a motor installed on the mounting plate through a universal shaft. The universal shaft includes a shaft body, and the two ends of the shaft body are respectively provided with mutually perpendicular X-direction connecting grooves and Z-direction connecting grooves, the X-direction connecting groove is hinged to the motor output shaft, and the Z-direction connecting groove is hinged to the roller brush bearing bracket.

[0007] Preferably, based on the above scheme, the roller brush bearing bracket close to the motor side also includes a connecting shaft, the end of the connecting shaft is provided with a card slot adapted to the Z-direction connecting groove, the card slot and the Z-direction connecting groove are connected by an adapter, four plug-in shafts are provided on the adapter, the four plug-in shafts are respectively arranged on the end faces of the four adapters, and every two are coaxially arranged.

[0008] Preferably, based on the above scheme, the connecting head is provided with a mounting hole, a bolt with a spring is inserted into the mounting hole, and two ends of the bolt are inserted through two sides of the clamping plate.

[0009] Preferably, based on the above solution, the mounting shaft is equipped with a roller brush.

[0010] Preferably, based on the above solution, two parallel supporting beams are arranged between the mounting plates.

[0011] The utility model discloses a device for automatically adjusting the height of a roller brush. A long hole is arranged on a mounting plate to provide space for a roller brush bearing bracket to float up and down. At the same time, a universal shaft is arranged at the output end of a motor. The X-direction connecting groove and the Z-direction connecting groove on the universal shaft can not only transmit the torque output by the motor to drive the mounting shaft to rotate, but also, due to the effect of the Z-direction connecting groove, when the mounting shaft encounters ground subsidence and the supporting force of the ground on it is reduced, the mounting shaft will bend toward the ground side around the Z-direction connecting groove due to its own gravity, so that the roller brush on the mounting shaft is always in contact with the ground, thereby improving its cleaning effect.
