Description

Technical Field

[0001] This utility model belongs to the field of photovoltaics, specifically a photovoltaic panel cleaning robot with automatic length adjustment. Background Technology

[0002] After the photovoltaic panels are installed, slide rails are installed on both sides for the photovoltaic panel cleaning robot to move on. Insertion holes are evenly distributed on the slide rails, so that several power rods on the power wheels of the photovoltaic panel cleaning robot can be inserted into the insertion holes to move.

[0003] However, due to site constraints, not all photovoltaic panels are quadrilateral when installing them; instead, they are often arranged in a wavy pattern on both sides. Consequently, the sliding rails also become wavy. Since the length of existing cleaning robots is limited, the pulling force on both sides becomes very large during the robot's movement, significantly reducing its lifespan. Therefore, there is an urgent need in this field for a photovoltaic panel cleaning robot with automatic length adjustment. Utility Model Content

[0004] In view of the shortcomings of existing photovoltaic panel cleaning robots, the technical problem to be solved by this utility model is to provide a photovoltaic panel cleaning robot with an automatically adjustable length, so that the photovoltaic panel cleaning robot can be better adapted to non-straight sliding rails.

[0005] To achieve the above objectives, according to one aspect of the present invention, the present invention is implemented through the following technical measures: a photovoltaic panel cleaning robot with automatic length adjustment, comprising: a frame, on which a snow removal device is provided, and on both sides of the frame a moving mechanism that provides power; the photovoltaic panel cleaning robot further comprising a connecting seat, the connecting seat being located at the lower end of the frame, and having a sliding groove on the connecting seat; a sliding rod capable of sliding along the sliding groove is provided in the sliding groove, and the lower end of the sliding rod is fixed to the moving mechanism, the upper end of the sliding rod being fixed by a nut; the upper end of the moving mechanism is also provided with a ball that contacts the connecting seat, the ball serving to reduce friction.

[0006] Furthermore, the frame includes two crossbeams connected by a connecting rod to form the frame. The upper ends of the two crossbeams are provided with sliding grooves, and the top surface of the sliding grooves is provided with two unsealed baffles. The snow removal device includes a blower and / or a powered auger. The blower is mounted on a blower frame, and the two sides of the blower frame are fixed to the crossbeams by bolts. The bolt tails are located in the sliding grooves, and the bolt shanks are locked between the two baffles. The blower and / or the auger are powered by a power supply device.

[0007] Furthermore, the moving mechanism includes a moving base, which is U-shaped. A motor fixing plate is provided between the two vertical plates of the U-shaped moving base. A motor is provided on the motor fixing plate, and the motor shaft of the motor passes through the motor fixing plate to provide a power wheel. Several power rods are arrayed on the circular outer wall of the power wheel. By rotating the power wheel, the power rods are alternately inserted into the walking insertion holes at the upper end of the walking slide rails on both sides of the photovoltaic panel. The moving base is also provided with walking wheels on both sides to clamp the walking slide rails.

[0008] Furthermore, the connecting seat is a hollow quadrilateral with openings at the front and rear. A transverse groove is provided on the lower surface of the connecting seat, and a wear-resistant block with high wear resistance is provided at the upper end of the groove. The nut is located at the upper end of the wear-resistant block.

[0009] Furthermore, there are multiple rolling balls, and each rolling ball is disposed in a rolling ball seat. The moving mechanism is also provided with a plug-in hole for the rolling ball seat to be inserted.

[0010] Compared with the prior art, the advantages of this utility model are: through the design of the connecting seat, and the provision of a sliding groove on the connecting seat, a sliding rod that can slide along the sliding groove is provided in the sliding groove, and the lower end of the sliding rod is fixed to the moving mechanism, so that the moving mechanism at the lower end of the moving mechanism can move back and forth along the sliding groove, thereby changing the overall length.

[0018] For descriptive purposes, this disclosure may use spatial relative terms such as “below,” “under,” “below,” “down,” “above,” “above,” “higher,” and “side (e.g., in a “sidewall”)” to describe the relationship between one component and another component as shown in the accompanying drawings. In addition to the orientations depicted in the drawings, the spatial relative terms are also intended to encompass different orientations of the device during use, operation, and / or manufacture. For example, if the device in the drawings is flipped, a component described as “below” or “under” other components or features would subsequently be positioned “above” said other components or features. Thus, the exemplary term “below” can encompass both “above” and “below” orientations. Furthermore, the device may be otherwise positioned (e.g., rotated 90 degrees or in other orientations), thus interpreting the spatial relative descriptive terms used herein accordingly.
