Abstract
Description
Technical Field
[0001] This utility model relates to the field of photovoltaic cleaning equipment technology, and in particular to a cleaning robot. Background Technology
[0002] Solar photovoltaic (PV) technology, as a renewable and clean energy source, has become a significant force in the global energy transformation. However, the surface of solar panels easily accumulates dirt, sand, and dust. Without timely and professional cleaning, this can lead to a decrease in the power output of the modules and a reduction in electricity generation. Therefore, cleaning robots are needed to clean PV panels.
[0003] Cleaning robots typically consist of a main body and roller brush assemblies at both the front and rear ends of the main body. The main body drives the roller brush assemblies to move and perform cleaning. Existing cleaning robots, as described in CN202420861670.1 and CN202510095564.6, are usually I-shaped. Their cleaning area depends on the length of the roller brush assembly. If the cleaning width is to be increased, the length of the roller brush assembly must be increased, which results in higher costs and increased load on the main body. Utility Model Content
[0004] To overcome the above-mentioned shortcomings, the purpose of this utility model is to provide a cleaning robot that greatly increases the cleaning width of the cleaning robot by arranging two roller brush components without increasing the length of the roller brush assembly.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is: a cleaning robot, comprising:
[0006] The fuselage is capable of moving along a first direction on a horizontal plane;
[0007] The roller brush assembly has two components, which are located on opposite sides of the machine body in a first direction and move synchronously with the machine body. The two roller brush assemblies are staggered in a second direction on the horizontal plane, and there is no gap between the rolling areas of the two roller brush assemblies in the second direction.
[0008] The beneficial effects of this invention are as follows: the two roller brush assemblies are staggered, forming a Z-shaped cleaning robot, and there are no gaps between the rolling areas of the two roller brush assemblies. This ensures that there are no blind spots between the two roller brush assemblies during robot movement, and at the same time, without increasing the length of the roller brush assemblies, the cleaning width of the robot is greatly increased simply by adjusting the position of the roller brush assemblies.
[0009] Furthermore, since the rolling areas of the two roller brush assemblies partially overlap, the positional requirements for the two roller brush assemblies are not as precise, making installation easier.
[0010] Furthermore, each of the roller brush assemblies extends beyond the two side edges of the machine body at both ends in the second direction. The length of the connection between the roller brush assembly and the machine body is relatively large compared to the total length of the roller brush assembly, which improves the stability of the connection between the roller brush assembly and the machine body. The two roller brush assemblies are symmetrical about the center point of the machine body, which improves the uniformity of force distribution on the machine body.
[0011] Furthermore, the adjacent sides of the rolling areas of the two roller brush assemblies extending along the first direction overlap, at which point the robot's cleaning width is at its maximum.
[0012] Furthermore, the roller brush assembly includes a connecting bracket, which is hinged to the machine body via a connector, and the position of the connecting bracket in the second direction can be adjusted via the connector, so that the position of the connecting bracket relative to the machine body can be adjusted according to the cleaning needs.
[0013] Furthermore, the connector includes a connecting part and a hinge part. The connecting part is provided with a hook, which engages with the connecting bracket. The connecting bracket can slide along the hook in a second direction. The hinge part is provided with hinge holes and guide holes spaced apart along a first direction. A hinge shaft is fixed on the machine body, which can be inserted into the hinge holes and the guide holes and rotate along the hinge holes and the guide holes.
[0014] Furthermore, the connecting bracket has a plurality of spaced locking holes along the second direction, and the connecting part is fixedly connected to the locking holes by locking members.
[0015] Furthermore, the hinge hole and the guide hole are respectively provided with openings facing downwards and upwards, and the hinge shaft corresponds to the hinge hole and the guide hole and can enter and exit the corresponding hinge hole and the guide hole from the opening.

[0028] See appendix Figure 1 and attached Figure 4 As shown, the present invention provides a cleaning robot, which includes a body 1 and two roller brush assemblies.
[0029] The machine body 1 is equipped with a traveling mechanism (existing technology, not described in detail here), which drives the machine body 1 to move along a first direction on the horizontal plane. Two roller brush assemblies are located on both sides of the machine body 1 in the first direction, that is, on the front and rear sides of the machine body 1 in the direction of travel, and are used to clean the photovoltaic panels. The two roller brush assemblies have the same structure and size, namely the front roller brush assembly 2a and the rear roller brush assembly 2b. Both the front roller brush assembly 2a and the rear roller brush assembly 2b are connected to the machine body 1 and move synchronously with the machine body 1.
[0030] The front roller brush assembly 2a and the rear roller brush assembly 2b are parallel to each other and both extend along a second direction on the horizontal plane, while the first and second directions are perpendicular. The front roller brush assembly 2a and the rear roller brush assembly 2b are staggered in the second direction, and there is no gap between the rolling areas of the front roller brush assembly 2a and the rear roller brush assembly 2b in the second direction. That is, during the robot's movement, there will be no gaps between the rolling areas of the rear roller brush assembly 2b and the rolling areas of the front roller brush assembly 2a that have not been cleaned.
[0031] Compared to the I-shaped structure of robots in existing technologies, in this example, the two roller brush assemblies are staggered, forming a Z-shaped cleaning robot, and there are no gaps between the rolling areas of the two roller brush assemblies. This ensures that there are no blind spots between the two roller brush assemblies during robot movement, and at the same time, without increasing the length of the roller brush assemblies, the cleaning width of the robot is greatly increased simply by adjusting the position of the roller brush assemblies.
[0032] The roller brush assembly includes a connecting bracket 21 and a roller brush body 22 rotatably connected to the connecting bracket 21. The roller brush body 22 contacts the photovoltaic array to achieve cleaning. The area traversed by the roller brush body 22 forms a rolling area, which is related to the length of the roller brush body 22 in a second direction.
[0033] In one embodiment, see Appendix Figure 3 As shown, the rolling areas of the front roller brush assembly 2a and the rear roller brush assembly 2b overlap along the adjacent edges extending in the first direction. That is, the adjacent ends of the roller brush body 22 of the front roller brush assembly 2a and the roller brush body 22 of the rear roller brush assembly 2b are close together, meaning they are close together along a straight line extending in the first direction. Figure 3 On the dotted line (in the diagram), the robot's cleaning width is at its maximum at this time.
[0034] At this time, in order to ensure the stability of the robot and make the body 1 be subjected to balanced forces in the second direction, the front roller brush assembly 2a and the rear roller assembly are symmetrical about the center of the body 1.
[0035] In one embodiment, see Appendix Figure 1 and attached Figure 2 As shown, the rolling area of the front roller brush assembly 2a and the rolling area of the rear roller brush assembly 2b partially overlap, that is, the projection of the roller brush body 22 of the front roller brush assembly 2a onto the rear roller brush assembly 2b partially overlaps with the roller brush body 22 of the rear roller brush assembly 2b.
[0036] In this embodiment, the positions of the front roller brush assembly 2a and the rear roller brush assembly 2b are not required to be so precise, which facilitates installation.
[0037] To improve the stability of the connection between the roller brush assembly and the body 1, both ends of each roller brush assembly extend beyond the two side edges of the body 1 in the second direction. In this case, the length of the connection between the roller brush assembly and the body 1 is relatively large compared to the length of the roller brush assembly itself, which improves the stability of the connection.
[0038] At this time, the front roller brush assembly 2a and the rear roller brush assembly 2b are still symmetrical about the center point of the body 1, so as to improve the uniformity of the force on the body 1.
[0039] In this embodiment, compared with the I-shaped cleaning robot, under the premise that the structure of the roller brush assembly remains unchanged, the staggered front roller brush assembly 2a and rear roller brush assembly 2b increase the cleaning width of the cleaning robot by 40%.
[0040] See appendix Figure 4 As shown, the connecting bracket 21 is hinged to the body 1 via the connector 3. The connecting bracket 21 can swing up and down relative to the body 1 to adapt to the cleaning of the photovoltaic system. The connecting bracket 21 can be adjusted in the second direction via the connector 3. At this time, the connecting bracket 21 can be adjusted in the second direction relative to the body 1, thereby adjusting the cleaning width of the cleaning robot according to the usage.
[0041] See appendix Figure 5 As shown, the connector 3 includes a connecting portion 31 and a hinge portion 32. The connecting portion 31 is provided with a hook 311, which engages with the connecting bracket 21. The hook 311 forms a groove, and a portion of the connecting bracket 21 can be inserted into the groove and press-fitted with it. The connecting bracket 21 can slide along the groove of the hook 311 in a second direction. When the hook 311 is engaged at different positions on the connecting bracket 21, the connector 3 is fixed to the connecting bracket 21 at different positions.
[0042] The roller brush assembly may separate from the connector 3 or move during the movement of the cleaning robot if it is only engaged by the hook 311 and the connecting bracket 21. Therefore, the connecting part 31 is also fixedly connected to the connecting bracket 21 by a locking member 312, which can be a bolt.
[0043] To facilitate the adjustment of the position of the connector 3 on the connecting bracket 21, the connecting bracket 21 is provided with a plurality of spaced locking holes along the second direction. The locking holes and the locking member 312 are threadedly connected. After the connector 3 is adjusted to its position on the connecting bracket 21, the connecting part 31 is fixedly connected to the locking hole through the locking member 312.
[0044] The hinge portion 32 is provided with hinge holes 321 and guide holes 322 spaced apart along a first direction. A hinge shaft 11 is fixed on the body 1, capable of being inserted into and rotating along the hinge holes 321 and guide holes 322. The guide hole 322 is elongated and accommodates the vertical movement of the connecting bracket 21. The hinge shaft 11 located within the guide hole 322 can also slide along it.
[0045] The hinge shaft 11 and hinge portion 32 are detachable to facilitate replacement of the roller brush assembly. The guide hole 322 has a downward-facing opening 3211, and the hinge interface also has an upward-facing opening 3211. The hinge shaft 11 corresponds to the hinge hole 321 and the guide hole 322 and can enter and exit the corresponding hinge hole 321 and guide hole 322 through the opening 3211. When the hinge shaft 11 leaves the hinge hole 321 and guide hole 322 through the opening 3211, the connector 3 separates from the body 1, thus achieving the disassembly of the roller brush assembly from the body 1, allowing for replacement and cleaning of the roller brush assembly.

Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it. They cannot be used to limit the protection scope of this utility model.
