Description

Technical Field

[0001] This application relates to the field of photovoltaic panel cleaning, and in particular to a three-section hybrid dual-brush structure. Background Technology

[0002] Existing photovoltaic (PV) panel cleaning equipment is used to clean batches of PV panels, reducing manual operation difficulty and improving cleaning efficiency. The equipment consists of a main body and a roller brush mounted at the front, with a motor installed on the main body to drive the roller brush. Because the equipment uses a metal frame, it is quite heavy. When placed on the PV panels, the weight causes the panels to bend and deform, resulting in tilting on both sides of the panels. However, existing equipment, in order to increase the cleaning area, lengthens the roller brush. The roller brush is then lifted at both ends due to the bending of the PV panels, creating gaps between the brush and the panels, preventing the brush from effectively cleaning the PV panels.

Detailed Implementation

[0029] The following is in conjunction with the appendix Figures 1-6 The present invention will be further described below. The following embodiments are only used to more clearly illustrate the technical solution of this application, and should not be used to limit the protection scope of the present invention.

[0030] In the description of this application, it should be noted that the orientations or positional relationships indicated by terms such as "center", "up", "down", "left", "right", "vertical", "horizontal", "inner", and "outer" are based on the orientations or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description. They are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0031] This application discloses a three-section hybrid dual-roller brush structure. (Refer to...) Figure 1 , Figure 2 and Figure 3 The system includes a first cleaning component 1, mounting bases 2 installed at both ends of the first cleaning component 1, and a second cleaning component 3 installed on the mounting bases 2. In this embodiment, two sets of second cleaning components 3 are provided and located at both ends of the first cleaning component 1. A rotating seat 4 is installed at the end of the second cleaning component 3. The rotating seat 4 is provided with a rotating shaft. The rotating seat 4 is rotatably engaged with the mounting base 2 through the rotating shaft. The mounting base 2 is provided with a mounting hole 20 for positioning the rotating shaft. The mounting base 2 is also fixed with a positioning part 21 for positioning the bottom surface of the rotating seat 4. The side of the positioning part 21 facing the side wall of the rotating seat 4 is arc-shaped to accommodate the rotation of the rotating seat 4 and reduce the friction between the rotating seat 4 and the mounting base 2.

[0032] Reference Figure 2 and Figure 4 The top surface of the rotating seat 4 is provided with several adjustment holes 5 along the circumferential direction with the rotation axis as the center. The mounting seat 2 is provided with positioning holes 6 that communicate with the adjustment holes 5. The positioning holes 6 are located on the rotation path of the adjustment holes 5, and positioning balls 7 are provided in the positioning holes 6.

[0033] Reference Figure 4 and Figure 5The lower end of the positioning hole 6 is arc-shaped. When the positioning ball 7 is located inside the positioning hole 6, the lower end of the positioning ball 7 enters the adjustment hole 5. The diameter of the lower end of the positioning hole 6 is smaller than the diameter of the positioning ball 7. The mounting base 2 is provided with a control component 8, which is used to control whether the positioning ball 7 can be moved out of the adjustment hole 5.

[0034] Reference Figure 2 and Figure 5 To improve the stability of the positioning ball 7 on the mounting base 2, a positioning ring 9 is provided around the outer periphery of the positioning hole 6 on the mounting base 2. The positioning ring 9 is used to position the positioning ball 7. The control component 8 includes a movable base 10 mounted on the mounting base 2 and an adjusting plate 11 mounted on the movable base 10 facing the positioning ring 9. The adjusting plate 11 includes a flattening part 111 and a bending part 112. The flattening part 111 is located on the top surface of the positioning ring 9 and contacts the top surface of the positioning ring 9. The bottom surface of the bending part 112 gradually increases in horizontal height, forming a space for the positioning ball 7 to enter. The distance between the top surface of the positioning ring 9 and the bottom surface of the adjusting hole 5 is consistent with the diameter of the positioning ball 7. When the flattening part 111 is above the positioning ring 9, the positioning ball 7 is blocked by the flattening part 111 and is always between the adjusting hole 5 and the positioning hole 6. The positioning ball 7 positions the rotating base 4 and the mounting base 2, becoming the positioning point between the two components. To improve the positioning effect of the positioning ball 7 on the mounting base 2 and the rotating base 4, two sets of positioning balls 7 are symmetrically arranged in this embodiment. In specific implementation, more than two positioning balls 7 can be set. In this embodiment, the two positioning balls 7 are easy to adjust and at the same time balance the positioning points, thereby improving the stability between the rotating base 4 and the mounting base 2.

[0035] Reference Figure 5 and Figure 6 To facilitate the movement of the movable seat 10 and thus control the positioning effect of the adjusting plate 11 on the positioning ball 7, an elastic element 12 is installed on the side of the movable seat 10 away from the adjusting plate 11. A positioning baffle 13 is located on the end of the elastic element 12 away from the adjusting plate 11. One end of the elastic element 12 presses against the movable seat 10, and the other end presses against the positioning baffle 13. When the movable seat 10 is in an unadjusted state, the elastic element 12 drives the flattening part 111 to remain above the positioning ring 9. When the movable seat 10 moves towards the positioning baffle 13, the elastic element 12 extends or retracts towards the positioning baffle 13. At this time, the bending part 112 moves above the positioning ring 9, allowing the positioning ball 7 to move and the rotating seat 4 to adjust its angle. When the movable seat 10 is released, the elastic element 12 drives the movable seat 10 to reset, the flattening part 111 moves back above the positioning ring 9, and the positioning ball 7 re-enters the adjusting hole 5.

[0036] Reference Figure 5To improve the telescopic stability of the elastic element 12, a positioning tube 14 is provided inside the movable seat 10, which is sleeved on one end of the elastic element 12. The end of the positioning tube 14 away from the positioning baffle 13 is sealed, which facilitates the fixing of the end of the elastic element 12 to the positioning tube 14. The other end of the elastic element 12 is connected to the positioning baffle 13. In this embodiment, the elastic element 12 is a spring.

[0037] Reference Figure 5 and Figure 6 To improve the stability between the movable seat 10 and the mounting seat 2, and to reduce the entry of debris into the extension and contraction position of the elastic element 12, thus affecting its extension and contraction, a cover plate 15 is installed on the mounting seat 2. In this embodiment, the cover plate 15 is fitted and fixed to the mounting seat 2; in specific implementations, it can also be fixed with bolts or clips. The cover plate 15 has a moving groove 16 located above the movable seat 10 along the extension and contraction direction of the elastic element 12. An adjusting block 17 is installed on the top surface of the cover plate 15, and a positioning rod 18 connected to the movable seat 10 is fixedly installed on the bottom surface of the adjusting block 17. The movable seat 10 has a hole for the positioning rod 18 to be inserted. By moving the adjusting block 17 along the length of the adjusting groove, the movable seat 10 is moved. To facilitate the operator's control of the adjusting block 17, several anti-slip patterns 19 are fixed on the top surface of the adjusting block 17. The anti-slip patterns 19 are arrow-shaped, and the arrows of the anti-slip patterns 19 point in the same direction as the extension and contraction direction of the spring, guiding the operator to move towards the positioning baffle 13.

[0038] Reference Figure 1 and Figure 2 In this embodiment, cleaning component 1 includes a mounting frame, a control shaft extending along the length of the mounting frame, a plurality of bristles extending along the length of the control shaft, a scraper mounted on the control shaft and alternately installed with the bristles, and a motor mounted at the end of the mounting frame for driving the control shaft to rotate. In this embodiment, two sets of control shafts are provided, and gears are installed at the ends of the control shafts to facilitate multiple sets of motor control. Cleaning component 2 3 has the same structure as cleaning component 1, and a rotating seat 4 is mounted on the end of the mounting frame near cleaning component 1, facilitating the installation of cleaning component 2 3 on the mounting seat 2.

[0039] The implementation principle of the three-section hybrid dual roller brush structure in this application embodiment is as follows: the cleaning component 1 is the same size as the equipment body. When the equipment is placed on the photovoltaic panel, the photovoltaic panel is affected by the gravity pressure of the equipment, and the photovoltaic panels on both sides of the equipment bend. At this time, the cleaning component 2 3 bends along the tilt angle of the photovoltaic panel and fits the surface of the photovoltaic panel. When the equipment moves, the cleaning component 1 and the two cleaning components 2 3 can completely clean the photovoltaic panel. When the photovoltaic panel is small, the cleaning component 2 3 needs to be retracted. The operator moves the adjusting block 17 according to the anti-slip texture 19 on the adjusting block 17. The movement of the adjusting block 17 moves the moving seat 10, which in turn retracts the elastic element 12. The moving seat 10 moves the flat part 111 out of the positioning ring 9, and the bending part 112 reaches above the positioning ring 9. At this point, the cleaning component 2 3 is rotated, and the positioning ball 7 moves upward due to the movement of the rotating seat 4, moving into the positioning ring 9 and the bending part 112. Then, another adjusting hole 5 moves below the positioning ball 7. If the angle is acceptable, the adjusting block 17 is released. If further adjustment is needed, it is adjusted to the desired adjusting hole 5, and then the adjusting block 17 is released again. This roller brush has high practicality and adaptability, and can be used for cleaning photovoltaic panels of various sizes. It also provides good cleaning results and reduces the possibility of missed areas.

[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
