Especially in places with large photovoltaic panels, to increase power generation, the cleaning frequency must be increased, and the efficiency of photovoltaic cleaning equipment determines the creation of economic value.

[0004] To improve efficiency, the most direct and effective way is to increase the length of the roller brush while keeping the same number of machines and equipment. At present, the overall length of the roller brush is 2.5 meters, but such a long roller brush brings great trouble to transportation and handling, and has higher requirements for handling equipment and handling personnel. Of course, the transportation cost will increase a lot. Some vehicles cannot be transported at all, and some places cannot be passed at all, especially cross-border sales and transportation are restricted. Summary of the invention

In order to improve efficiency and solve the problems of transportation and handling, the whole is divided into sections. The two sections can be disassembled and transported during transportation, reducing the overall length, bringing convenience to logistics transportation and handling. A quick-disassembly and quick-assembly structure is made for installation. When in use, the two sections can be directly spliced ​​and some connecting bolts can be installed to complete the assembly. At the same time, the gap between the two sections of bristles is reduced through structural optimization, which can achieve the effect of traceless cleaning.

[0031] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0032] Example 1

[0033] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the present invention provides a technical solution: an ultra-long and efficient roller brush mechanism of a photovoltaic unmanned cleaning robot, comprising a transmission motor 3, the transmission motor 3 is connected to a transmission connecting shaft 4 through a transmission coupling 19, and the transmission connecting shaft 4 is connected to a first roller brush bristle fixing shaft 7 through a roller brush transmission device 5, wherein roller brush bristles 17 are arranged on the first roller brush bristle fixing shaft 7, and a roller brush transmission shaft sleeve 8 is fixedly installed inside the other end of the roller brush bristles 17, and the roller brush transmission shaft sleeve 8 is detachably connected to the roller brush transmission shaft 13 through a roller brush transmission shaft sleeve pin 12, the roller brush transmission shaft sleeve 8 and the roller brush transmission shaft 13 are in a plug-in form, and the other end of the roller brush transmission shaft 13 is fixed in the second roller brush bristle fixing shaft 14, and the second roller brush bristle fixing shaft 14 is also provided with roller brush bristles 17.

[0034] In this embodiment, the transmission motor 3 is used as a power source to drive the transmission connecting shaft 4 to rotate, and the transmission connecting shaft 4 is then driven by the roller brush transmission device 5 to drive the first roller brush bristle fixing shaft 7 to rotate, and the first roller brush bristle fixing shaft 7 is connected to the second roller brush bristle fixing shaft 14 through the roller brush transmission shaft sleeve 8 and the roller brush transmission shaft 13. The combination will also rotate together under the connection, so that the transmission motor 3 drives the first roller brush bristle fixing shaft 7 and the roller brush bristles 17 on the second roller brush bristle fixing shaft 14 to rotate, thereby achieving the effect of cleaning the photovoltaic panel;

[0035] Among them, since the roller brush drive sleeve 8 and the roller brush drive shaft 13 are plugged in through the roller brush drive sleeve pin 12, and the plug interface on the roller brush drive shaft 13 is open, the roller brush drive sleeve 8 and the roller brush drive shaft 13 are only subjected to steering torque under the action of the roller brush drive sleeve pin 12. Therefore, the first roller brush bristle fixing shaft 7 and the second roller brush bristle fixing shaft 14 can be quickly disassembled and assembled without being affected by other external forces.

[0036] Example 2

[0037] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, an ultra-long and efficient roller brush mechanism of a photovoltaic unmanned cleaning robot provided by an embodiment of the present invention also includes a first roller brush beam 1, a transmission connecting shaft outer cover 2 is fixedly installed on the first roller brush beam 1, a transmission motor 3, a transmission connecting shaft 4 and a transmission coupling 19 are all arranged in the transmission connecting shaft outer cover 2, and the transmission motor 3 is fixedly connected to the first roller brush beam 1, a first roller brush support frame 6 is fixedly installed on one end of the first roller brush beam 1, and the transmission connecting shaft 4 and the first roller brush bristle fixing shaft 7 are both arranged through the first roller brush support frame 6, and the roller brush transmission device 5 is fixedly installed on the first roller brush support frame 6, A connecting plate 18 is installed on the other end of the first roller brush cross beam 1, and a second roller brush support frame 9 is installed on the connecting plate 18. A roller brush transmission shaft bearing 10 is fixedly installed in the second roller brush support frame 9, and the roller brush transmission shaft sleeve 8 is connected to the roller brush transmission shaft bearing 10, and a bearing cover plate 11 is provided on the side of the roller brush transmission shaft bearing 10 away from the roller brush transmission shaft sleeve 8. The other end of the connecting plate 18 is detachably connected to the second roller brush cross beam 16, and the other end of the second roller brush cross beam 16 is fixedly installed with a third roller brush support frame 15, and the other end of the third roller brush support frame 15 is rotatably connected to the second roller brush bristle fixing shaft 14.

[0038] In this embodiment, the main purpose is to fix the transmission component. Since the first roller brush bristle fixing shaft 7 and the second roller brush bristle fixing shaft 14 are detachably connected, the corresponding first roller brush cross beam 1 and the second roller brush cross beam 16 are also detachably connected. This design facilitates the disassembly of the first roller brush bristle fixing shaft 7 and the second roller brush bristle fixing shaft 14, and combined with the connection method between the roller brush transmission shaft sleeve 8 and the roller brush transmission shaft 13, it can be obtained that the width of the gap between the roller brush bristles 17 on the first roller brush bristle fixing shaft 7 and the roller brush bristles 17 on the second roller brush bristle fixing shaft 14 in the natural state is the width of the second roller brush support frame 9. In actual use, the roller brush bristles 17 will be deformed when being pressed on the photovoltaic panel, and the bristles on the side will be squeezed and bent. At this time, the roller brush bristles 17 on the first roller brush bristle fixing shaft 7 and the roller brush bristles 17 on the second roller brush bristle fixing shaft 14 can cover the gap.

[0039] Working principle:

[0040] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, the present invention is to achieve segmented docking assembly, and the structural design of the intermediate supporting connection part is particularly important. First, the roller brush transmission device 5 first drives the first roller brush bristle fixing shaft 7 to rotate. The first roller brush bristle fixing shaft 7 must be able to drive the second roller brush bristle fixing shaft 14. Therefore, the roller brush transmission shaft sleeve 8 and the roller brush transmission shaft sleeve bayonet 12 are welded on the first roller brush bristle fixing shaft 7, and the roller brush rotating shaft 13 is welded on the second roller brush bristle fixing shaft 14. The roller brush rotating shaft 13 and the roller brush transmission shaft sleeve 8 are designed The first roller brush bristle fixing shaft 7 is tapered, and the two are closely matched when plugged in. In addition, a groove is opened on the first roller brush bristle fixing shaft 7, and a roller brush transmission shaft sleeve bayonet 12 is welded on the roller brush transmission shaft sleeve 8. The groove on the roller brush transmission shaft 13 is clamped to the roller brush transmission shaft sleeve bayonet 12 of the roller brush transmission shaft sleeve 8 to transmit torque. This design cleverly, stably and accurately connects the first roller brush bristle fixing shaft 7 and the second roller brush bristle fixing shaft 14, so that the first roller brush bristle fixing shaft 7 drives the second roller brush bristle fixing shaft 14 to rotate;

[0041] Then, a stable supporting structure of the roller brush transmission shaft sleeve 8 and the roller brush transmission shaft 13 is carried out, and it is necessary to ensure that the gap between the first roller brush bristle fixing shaft 7 and the second roller brush bristle fixing shaft 14 is very small. For this purpose, a second roller brush support frame 9 is provided, with an 8mm thick roller brush transmission shaft bearing 10 inside. The roller brush rotating shaft 13 passes through the roller brush transmission shaft bearing 10 and is inserted into the first roller brush bristle fixing shaft 7 and is locked with the roller brush transmission shaft sleeve pin 12. Among them, the second roller brush support frame 9 can be made of aluminum profiles and CNC precision processing. It has good strength and light weight, and the surface is polished to solve the problem of two sections of brushes entangled with each other affecting the transmission and cleaning quality.

[0042] The above are only preferred embodiments of the present invention and are not intended to limit the present invention in other forms. Any technician familiar with the profession may use the technical contents disclosed above to change or modify them into equivalent embodiments with equivalent changes and apply them to other fields. However, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention without departing from the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
