[0002] Photovoltaic power plant cleaning robots typically run along the edges of photovoltaic modules to remove dust and dirt from their surfaces, improving power generation efficiency. However, due to installation deviations during photovoltaic module installation, adjacent modules may have height differences or lateral misalignments exceeding a certain value (e.g., 10mm), forming stepped obstacles. These obstacles can prevent the cleaning robot's wheels and guide wheels from passing smoothly, causing the robot to jam, slip, or even tip over, affecting cleaning efficiency and equipment safety.

[0003] In existing technologies, cleaning robots typically rely on the straightness and flatness of component edges for operation, lacking adaptive designs for obstacles with large deviations. Therefore, there is an urgent need for a device that can assist cleaning robots in navigating stepped obstacles to improve the robot's operational stability and adaptability. Utility Model Content

The singular forms “a,” “the,” or “the” used in the specification and claims of this invention are also intended to include the plural forms, unless the context clearly indicates otherwise.

[0019] It should be understood that the terms "first," "second," and similar words used in the specification and claims of this utility model do not indicate any order, quantity, or importance, but are merely used to distinguish the features. Similarly, the terms "an" or "a" do not indicate a quantity limitation, but rather indicate the presence of at least one. Unless otherwise stated, the terms "front," "back," "left," "right," "upper," "lower," and similar words appearing in this utility model are for ease of explanation only and are not limited to a specific location or spatial orientation. The terms "comprising" or "including" are an open-ended expression, meaning that the element preceding "comprising" or "including" covers the element following "comprising" or "including" and its equivalents, which does not exclude that the element preceding "comprising" or "including" may also include other elements. If "several" appears in this utility model, it means two or more.

[0020] Please refer to Figures 1 to 22 As shown, this utility model discloses an obstacle-crossing guidance device 500, which is used to assist the guide wheel 300 of the cleaning robot 200 to pass through the steps 401 on the left and right sides of two adjacent photovoltaic modules 400. It includes: a clamping component 1, a supporting component 2 and a roller assembly 3.

[0021] Please refer to Figures 1 to 22 As shown, the clamping component 1 includes two arms, namely a first arm 101 and a second arm 102. The first arm 101 and the second arm 102 are perpendicularly connected to each other to form an L-shaped receiving space 10A located on the inner side. Each arm includes a main board 11 and two side plates 12 formed by bending outwards from opposite ends of the main board 11. A clamping space 10B facing outwards is formed between the main board 11 and the corresponding side plate 12. Here, "inner side" and "outer side" are relative terms. If the receiving space 10A formed by the perpendicular connection of the first arm 101 and the second arm 102 is located on the inner side, then the clamping spaces 10B formed between the main board 11 and the corresponding side plate 12 are both facing outwards.

[0022] like Figure 1 and Figure 3 As shown, steps 401 are provided on the left and right sides of two adjacent photovoltaic modules 400; as Figure 2As shown, the first arm 101 and the second arm 102 are respectively used to clamp the frames of two adjacent photovoltaic modules 400 at the step 401. That is, because the step 401 creates an obstacle, it is not convenient for the guide wheels 300 of the cleaning robot 200 to pass smoothly; this utility model provides an obstacle-crossing guiding device 500 at the step 401, filling the obstacle created by the step 401, thereby facilitating the guide wheels 300 of the cleaning robot 200 to cross the obstacle. The clamping component 1 serves to clamp the frame of the photovoltaic module 400 while simultaneously positioning the supporting component 2.

[0023] Please refer to Figures 1 to 10 As shown, the obstacle-crossing guide device 500 provided at the step 401 of this utility model includes not only the clamping component 1, but also a support component 2 located within the receiving space 10A. The opposite ends of the support component 2 are respectively connected and positioned to the main plate 11 of each arm of the clamping component 1. The support component 2 has a gap 20A extending from one of the two arms (e.g., the first arm 101) towards the other (e.g., the second arm 102), facilitating the positioning and sliding of the roller assembly 3. The function of the support component 2 is to provide support and sliding limit for the roller assembly 3.

[0024] Please refer to Figures 2 to 7 As shown, the obstacle-crossing guide device 500 provided at the step 401 of this utility model further includes a roller assembly 3. The roller assembly 3 includes at least two rollers 30 arranged in a row, each roller 30 being positioned at the gap 20A on the support member 2. The rollers 30 are movable on the support member 2 along the extending direction of the gap 20A to bring the at least two rollers 30 closer together and further apart. Figure 5 The orientation described herein refers to the extension direction of the gap 20A being front-to-back, consistent with the extension direction of the two parallel connecting rods 20 described below. The function of the roller assembly 3 is to contact the guide wheel 300 of the cleaning robot 200, facilitating the cleaning robot 200 to cross obstacles.

[0025] Please refer to Figures 4 to 8 As shown, the support component 2 includes two parallel connecting rods 20, and the gap 20A is formed between the two connecting rods 20. When the support component 2 includes two parallel connecting rods 20, the gap 20A extends to the maximum extent from the inner wall surface of the main board 11 of the first arm 101 to the inner wall surface of the main board 11 of the second arm 102.

[0026] Please refer to Figures 10 to 13 as well as Figures 17 to 19The roller 30 has two large-diameter portions 31 at the top and bottom and a connecting post 32 in the middle. Each of the two opposite ends of the connecting post 32 has a large-diameter portion 31. The connecting post 32 is vertically inserted into the gap 20A, and the two large-diameter portions 31 are respectively located above and below the two connecting rods 20. Here, the connecting post 32 is at least one, including two specific cases: Please refer to Figures 10 to 13 In the first implementation method, since the upper large-diameter part 31 and the lower connecting post 32 are integrally formed, and the lower large-diameter part 31 and the upper connecting post 32 are integrally formed, that is, there are two connecting posts 32, one above the other, and they need to be connected as one unit. Therefore, the upper large-diameter part 31, the lower large-diameter part 31, and the two connecting posts 32 all need to be hollow. This makes it easier for a set of fasteners 7 to pass through from above, and then the two large-diameter parts 31 can be fixedly connected as one unit by the stop and limit of the lower part by the washer 8 and the nut 9. Please refer to Figures 17 to 19 In the second embodiment, the connecting post 32 is a single, solid piece, meaning the entire roller 30 is a single, solid body. This eliminates the need for a set of fasteners 7, washers 8, and nuts 9; the two connecting rods 20 are secured solely by the recess 33 described below. Of course, the difference between the first and second embodiments lies in the assembly sequence.

[0027] In Embodiment 1, the upper and lower large-diameter portions 31 are separately arranged. Therefore, after the two connecting rods 20 are first fixed in the clamping member 1 to form the gap 20A between the two connecting rods 20, the upper and lower large-diameter portions 31 are then locked. In Embodiment 2, the rollers 30 are integrally arranged. Therefore, the inner, shorter connecting rod 20 is first fixed in the clamping member 1. Then, the row of integrally arranged rollers 30 is secured to the shorter connecting rod 20 through the recess 33. Finally, the outer, longer connecting rod 20 is also fixed in the clamping member 1 and secured to the recess 33. The inner and outer sides mentioned here refer to... Figure 5 From the angle shown, the two parallel connecting rods 20 define the left and right movement space. Therefore, the shorter connecting rod 20 can be considered to be on the left, and the longer connecting rod 20 can be considered to be on the right. In summary, it can be seen that the fixing method using a set of fasteners 7, washers 8, and nuts 9 in Implementation Method 1 is simpler than the other implementation method.

[0028] Please refer to Figure 8 As shown, the diameter of the large-diameter portion 31 is greater than the width of the gap 20A. Please refer to... Figure 13 As shown, the cross-sectional radius of the connecting post 32 is smaller than the cross-sectional radius of the large-diameter portion 31, and the roller 30 forms a recess 33 at the position of the connecting post 32 relative to the two large-diameter portions 31. The function of the recess 33 is to allow the connecting rod 20 to be embedded in the recess 33 to achieve movement limitation of the roller 30 on the connecting rod 20.

[0029] Please refer to Figure 15 and Figure 16 As shown, the height of the connecting post 32, i.e., the opening of the recess 33, is smaller than the height of the guide wheel 300. When the guide wheel 300 is matched with each of the rollers 30, the guide wheel 300 can contact the two large-diameter portions 31 of the roller 30. This facilitates the passage of the guide wheel 300 and provides force support to the guide wheel 300.

[0030] Please refer to this carefully. Figure 20 As shown, the obstacle-crossing guide device 500 is also equipped with a locking mechanism 4 for easy installation and disassembly. The side plate 12 is provided with a screw hole 120. The locking mechanism 4 includes a bolt 40 and the screw hole 120. The bolt 40 passes through the screw hole 120 and presses against the frame of the photovoltaic module 400 to press and position the clamping component 1 on the frame of the photovoltaic module 400. And / or, the obstacle-crossing guide device 500 and the frame of the photovoltaic module 400 are connected by adhesive at the point of contact. That is to say, in addition to the clamping component 1 clamping the frame of the photovoltaic module 400, it is preferable to also provide a locking mechanism 4 to press and position the clamping component 1 on the frame of the photovoltaic module 400, thus ensuring stability and preventing it from easily detaching from the frame of the photovoltaic module 400.

[0031] Please refer to Figure 21As shown, the obstacle-crossing guide device 500 is further provided with an elastic mechanism 5 between the two connecting rods 20. The elastic mechanism 5 is one of a spring and a spring sheet (in a specific embodiment, a compression spring). The roller assembly 3 has two rollers 30 arranged in a row. The elastic mechanism 5 is located between the foremost roller 30 in the row and the first arm 101, and between the last roller 30 in the row and the second arm 102. When the guide wheel 300 travels between any two adjacent rollers 30 in a row, the two rollers 30 can move in opposite directions to compress the elastic mechanism 5. The elastic force of the elastic mechanism 5 is released so that after the guide wheel 300 has passed all the rollers 30 on one side and moved away, all the rollers 30 can move in opposite directions again to reset. In other words, each of the rollers 30 can move on the support member 2. Therefore, when two adjacent rollers 30 come into contact with the guide wheel 300, each roller 30 will move due to the pressure of the guide wheel 300. After the guide wheel 300 crosses the obstacle-crossing guide device 500, it needs to return to its original position. Therefore, the elastic mechanism 5 is designed to enable the rollers 30 of the obstacle-crossing guide device 500 to return to their original position in order to prepare for the next crossing of the guide wheel 300.

[0032] Please refer to Figure 22 As shown, the obstacle-crossing guiding device 500 also includes a limiting structure 6, which is one of a limiting plate and a limiting block (specifically, a limiting plate). The limiting structure 6 at least abuts against the upper surface of the roller 30. That is, the limiting structure 6 at least includes a first limiting member 61 abutting against the upper surface of the roller 30. The first limiting member 61 can ensure that the upper surface of the roller 30 does not exceed the surface of the photovoltaic module 400, avoiding affecting the operation of the cleaning robot 200; in other optional embodiments, the limiting structure 6 also includes a second limiting member (not shown) abutting against the lower surface of the roller 30. The first limiting member 61 and the second limiting member together can ensure that the roller 30 runs within a specific upper and lower range. That is, from Figure 5 As shown in the diagram, the two parallel connecting rods 20 define the lateral movement space, the first arm 101 and the second arm 102 define the front-to-back movement space, and the first limiting member 61 and the second limiting member define the vertical movement space. Therefore, the clamping component 1, the supporting component 2, and the limiting structure 6 together define the range of motion of the roller 30.

[0033] Please refer to Figures 1 to 22As shown, the connecting rod 20 is hollow inside and has drainage holes (not labeled), and each connecting rod 20 has opposite ends connected to one of the clamping spaces 10B. This arrangement prevents water and dust accumulation.

[0034] The height of the roller assembly 3 is less than or equal to the thickness of the photovoltaic module 400. This arrangement of the roller assembly 3 facilitates the obstacle-crossing guide device 500's ability to smoothly traverse the step 401 between two adjacent photovoltaic modules 400. The major diameter portion 31 of each roller 30 may be the same or different. This arrangement of each roller 30 increases its adaptability in filling the step 401. In other words: Please refer to... Figure 4 and Figure 5 When the first roller 301 and the second roller 302 have been set and filled at the step 401, there is still remaining space. If the remaining space is not enough to place the roller 30 that is the same size as the first two rollers, a smaller third roller 303 can be selected. The third roller 303 is arranged in a row with the two larger first rollers 301 and second rollers 302, which can make full use of the space.

[0035] In this specific embodiment, the clamping component 1 and the supporting component 2 are made of aluminum alloy. The clamping component 1 is specially lined with an anti-slip rubber pad to enhance clamping stability. The roller 30 is made of polyurethane, which is wear-resistant and elastic.

[0036] Please refer to Figures 1 to 22 As shown, a photovoltaic support system 600 includes a plurality of photovoltaic modules 400, with at least two adjacent photovoltaic modules 400 having steps 401 formed on both sides. It also includes an obstacle-crossing guide device 500 as described above, the obstacle-crossing guide device 500 being disposed at each of the steps 401. As is known to those skilled in the art, a cleaning robot 200 cleans the surface of the photovoltaic modules 400. The cleaning robot 200 includes an upper mechanism (not shown), a middle mechanism (not shown), and a lower mechanism (not shown). The upper mechanism includes two upper traveling wheels, two upper guide wheels, and a drive motor for providing power and running along the upper frame of the photovoltaic modules 400; the middle mechanism includes a transmission rod, a brush, and a control system for driving the brush to clean the module surface; the lower mechanism includes two lower traveling wheels, two lower guide wheels, and a drive motor for running along the lower frame of the photovoltaic modules 400. Figure 15 and Figure 16 The guide wheel 300 shown is one of two upper traveling wheels or two lower guide wheels.

[0037] In summary, compared to existing technologies, this invention, by incorporating an obstacle-crossing guide device 500 comprising a clamping component 1, a supporting component 2, and a roller assembly 3, facilitates the cleaning robot 200's crossing of stair obstacles. The photovoltaic support system 600 includes the obstacle-crossing guide device 500 as described above. Therefore, this invention improves the operational stability and adaptability of the cleaning robot 200.

[0038] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. The understanding of the present utility model should be based on those skilled in the art. Although the present utility model has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still make modifications or equivalent substitutions to the present utility model. All technical solutions and improvements that do not depart from the spirit and scope of the present utility model should be covered within the scope of the claims of the present utility model.
