Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic panel cleaning robots, and more specifically, to a roller brush driving device of a photovoltaic panel cleaning robot. Background Art

[0002] A photovoltaic panel is a device that can convert sunlight irradiation into electric energy. When the surface of a photovoltaic panel is used for a long time, dust is likely to accumulate, affecting the power generation efficiency. Therefore, it is necessary to clean the photovoltaic panels of a photovoltaic power station regularly. The manual cleaning method is time-consuming and laborious, and is likely to damage the photovoltaic panels. Therefore, robots have emerged on the market to replace manual labor for cleaning photovoltaic panels.

[0003] In general, the driving device of the cleaning component of traditional cleaning robots is installed on the frame that drives the roller brush to rotate. For example, the structure in the patent application CN116111935A. Although this structure is simple, it makes the overall cleaning structure relatively bulky.

[0004] Based on the above problems, the applicant modified this traditional cleaning robot, designed it as a detachable structure as a whole, and set the driving device of the cleaning structure between the cleaning structure and the walking structure. Although this structure can not only realize the modular design of the cleaning robot, which is convenient for installation and disassembly, however, in order to achieve its lightweight modular design, the adapter frame between the cleaning structure and the walking structure is not easy to be too large or too thick. When the driving structure is installed, using the traditional method of fixing the driving motor with screws will cause the screws to become loose after long-term use, resulting in interference with the chain and even affecting its operation.

[0005] Therefore, it is necessary to propose a roller brush driving device for a photovoltaic panel cleaning robot to solve the above problems. Summary of the Utility Model

[0006] The utility model provides a roller brush driving device for a photovoltaic panel cleaning robot to solve the problem that the bolts for fixing the motor in the existing traditional motor installation are likely to become loose, affecting the installation stability of the motor and its operation effect.

[0007] According to one aspect of the present utility model, a roller brush driving device for a photovoltaic panel cleaning robot is provided. The photovoltaic panel cleaning robot includes a frame, a traveling device, and a roller brush assembly. The traveling device is installed on both sides of the frame. The roller brush assembly is connected to the frame through an adapter bracket. The roller brush driving device is installed on the adapter bracket. The adapter bracket includes an adapter plate, a motor, and a sprocket. A receiving groove is provided on the adapter plate. The sprockets are spaced and installed in the receiving groove. A cover plate is provided outside the receiving groove. A transfer bearing is installed at the output end of the motor. An aluminum plate is installed on the outer ring of the transfer bearing through screws. The aluminum plate is connected to the adapter plate, and the output end of the motor is drivingly connected to one of the sprockets.

[0008] Preferably, based on the above solution, the inner ring of the transfer bearing is fixedly connected to the output shaft of the motor, and the outer ring of the transfer bearing is connected to the aluminum plate through screws.

[0009] Preferably, based on the above solution, a countersunk stud is provided on the receiving groove. A screw hole is provided inside the countersunk stud. A bolt is installed on the aluminum plate. The bolt is inserted into the screw hole.

[0010] Preferably, based on the above solution, the countersunk stud is provided inside the inner edge surface of the receiving groove.

[0011] Preferably, based on the above solution, the sprocket includes a driving sprocket and a driven sprocket. The driving sprocket and the driven sprocket are connected by a chain. The output end of the motor is drivingly connected to the driving sprocket.

[0012] Preferably, based on the above solution, a chain tensioning frame is further installed in the receiving groove. A tensioning wheel is installed at the top of the chain tensioning frame. The bottom of the chain tensioning frame is hingedly installed at the bottom of the receiving groove through a rotating shaft. A torsion spring is installed on the rotating shaft. The free end of the torsion spring abuts against the inner edge side surface of the receiving groove.

[0013] For the roller brush driving device of a photovoltaic panel cleaning robot of the present utility model, by installing a transfer bearing at the output end of the motor, while ensuring that the output shaft of the driving motor can continue to rotate through the transfer bearing, the fixed installation of the motor and the aluminum plate is ensured. At the same time, the fixed connection with the adapter plate is realized by combining the screws on the aluminum plate. This not only enhances the installation stability of the motor, but also, by arranging the screws for installing the motor entirely on the adapter plate on the side away from the installation groove, it can effectively avoid the problem that the loosened screws interfere with the drive chain even if the motor becomes loose during operation.
