Description

Technical Field

[0001] This application relates to the field of photovoltaic cleaning, specifically 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. The surface of solar panels easily accumulates dirt, sand, and dust. Without timely and professional cleaning, this can lead to a 40%–60% reduction in module power output and a 20%–30% decrease in overall power generation. Therefore, the concept of improving power plant output and efficiency through proper and scientific cleaning of solar panels and meticulous maintenance of the modules has gained industry recognition.

[0003] Traditional cleaning methods require significant manpower and resources, and are inefficient, consume excessive water, and have high overall costs. Furthermore, large-scale ground-mounted power plants in western regions require frequent and long-term cleaning, and the lack of readily available water makes manual cleaning of photovoltaic modules impractical.

[0004] Existing photovoltaic module cleaning robots are too complex and heavy due to the need to overcome obstacles such as the settling and misalignment of photovoltaic modules, resulting in high costs. However, some ground-mounted power stations do not have these obstacle-crossing problems, such as panels with an inclination angle of less than 15 degrees. These ground-mounted power stations do not need expensive and complex cleaning robots, but rather a cheaper and lightweight cleaning robot that can meet daily cleaning needs.

Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. In addition, it should be understood that the specific embodiments described herein are only for illustration and explanation of this application and are not intended to limit this application. In this application, unless otherwise stated, directional terms such as "up," "down," "left," and "right" generally refer to up, down, left, and right in the actual use or working state of the device, specifically the drawing directions in the accompanying drawings.

[0033] This application provides a method, which will be described in detail below. It should be noted that the order of description of the following embodiments is not intended to limit the preferred order of the embodiments of this application. Furthermore, in the following embodiments, the descriptions of each embodiment have their own emphasis; parts not described in detail in a certain embodiment can be referred to in the relevant descriptions of other embodiments.

[0034] like Figures 1-2 As shown, this application provides a cleaning robot 100, including a long strip-shaped body 110 and two roller brushes 120. The body of the cleaning robot 100 is made of aluminum alloy, which saves manufacturing costs.

[0035] The elongated vehicle body 110 includes two long sides 111 and two short sides 112. A first mounting plate 113 and a second mounting plate 114 are respectively disposed on the two short sides 112. The roller brushes 120 are a first roller brush 121 and a second roller brush 122. The first end 123 of the first roller brush is rotatably mounted to the first mounting plate 113. The first end 123 of the first roller brush passes through the first mounting plate 113 and extends to the side of the first mounting plate 113 opposite to the second mounting plate 114. The first end 125 of the second roller brush is rotatably mounted to the second mounting plate 114. The first end 125 of the second roller brush passes through the second mounting plate 114 and extends to the side of the second mounting plate 114 opposite to the first mounting plate 113. The second end 124 of the first roller brush and the second end 126 of the second roller brush are coaxially connected.

[0036] Furthermore, the cleaning robot 100 also includes a rectangular frame 130, and a long strip 131 is installed on the top of the rectangular frame 130. The long strip 131 is divided into a first area 132 and a second area 133. The first area 132 includes a protrusion 134. An electrical control box 135 is installed on the first area 132 of the long strip 131. The electrical control box 135 is fixedly connected between the rectangular frame 130. The top of the electrical control box 135 protrudes from the rectangular frame 130 and the electrical control box 135 is located below the protrusion 134 to protect the electrical control box 135 from rainwater and prevent the electrical control box 135 from malfunctioning after encountering water.

[0037] Furthermore, the cleaning robot 100 also includes a photovoltaic panel 140, which is installed on the top of the second area 133 of the long strip 131. The photovoltaic panel 140 is connected to the electrical control box 130 via wires. The photovoltaic panel 140 converts solar energy into electrical energy and transmits it to the electrical control box 130 for storage via wires.

[0038] Furthermore, the cleaning robot 100 also includes at least one sensor 141, distributed at the bottom of the rectangular frame 130. The sensor 141 of the cleaning robot 100 can sense the location of the cleaning robot 100, preventing the cleaning robot 100 from falling off the photovoltaic module. When the cleaning robot 100 reaches the edge of the photovoltaic module, it will automatically stop moving.

[0039] like Figure 3 As shown, the elongated vehicle body 110 includes a first power mechanism 150, which is mounted on one side of the first mounting plate 113. The first power mechanism 150 includes a first wheel 151, a first wheel motor 152, a first gear 153, a second gear 154, and a transmission chain 155.

[0040] A first wheel 151 is rotatably mounted to the side of a first mounting plate 113 facing a second mounting plate 114; the first wheel 151 includes a first axle (not shown), which passes through the first mounting plate 113 and extends to the side of the first mounting plate 113 opposite to the second mounting plate 114; the traveling direction of the first wheel 151 is perpendicular to the extending direction of the cleaning robot 100; a first wheel motor 152 is mounted to the side of the first mounting plate 113 facing a second mounting plate 114; the first wheel motor 152 includes a first power output shaft (not shown), which passes through the first... Mounting plate 113 extends to the side of the first mounting plate 113 opposite to the second mounting plate 114; first gear 154 is located on the side of the first mounting plate 113 opposite to the second mounting plate 114 and is fixed to the first axle (not shown); second gear 155 is located on the side of the first mounting plate 113 opposite to the second mounting plate 114 and is fixed to the first power output shaft (not shown); transmission chain 155 is sleeved on the axle surface of the first gear 153 and the second gear 154, and the inner sidewall of the transmission chain 155 is provided with tooth holes (not shown) to mesh with the first gear 153 and the second gear 154.

[0041] like Figure 4 As shown, the elongated vehicle body 110 also includes a second power mechanism 160, which is mounted on one side of the second mounting plate 114. The second power mechanism 160 includes a first wheel 151, a first wheel motor 152, a first gear 153, a second gear 154, and a transmission chain 155.

[0042] A first wheel 151 is rotatably mounted to the side of the second mounting plate 114 facing the first mounting plate 113; the first wheel 151 includes a first axle (not shown), which passes through the second mounting plate 114 and extends to the side of the second mounting plate 114 opposite to the first mounting plate 113; the traveling direction of the first wheel 151 is perpendicular to the extending direction of the cleaning robot 100; a first wheel motor 152 is mounted to the side of the second mounting plate 114 facing the first mounting plate 113; the first wheel motor 152 includes a first power output shaft (not shown), which passes through... A second mounting plate 114 extends to the side of the second mounting plate 114 opposite to the first mounting plate 113; a first gear 153 is disposed on the side of the second mounting plate 114 opposite to the first mounting plate 113 and fixed to the first axle (not shown); a second gear 154 is disposed on the side of the second mounting plate 114 opposite to the first mounting plate 113 and fixed to the first power output shaft (not shown); a transmission chain 155 is sleeved on the axle surface of the first gear 153 and the second gear 154, and the inner sidewall of the transmission chain 155 is provided with tooth holes for meshing with the first gear 153 and the second gear 154.

[0043] like Figures 3-4As shown, the cleaning robot 100 has two third gears 156. The third gears 156 are fixed to the first end 123 of the first roller brush and the first end 125 of the second roller brush, respectively. One third gear 156 is located on the side of the first mounting plate 113 away from the second mounting plate 144, and the other third gear 156 is located on the side of the second mounting plate 144 away from the first mounting plate 113. The transmission chain 155 meshes with the third gears 156.

[0044] In this embodiment, the first wheel motor 152 drives the first power output shaft (not shown) to rotate. The rotation of the first power output shaft (not shown) drives the first gear 153 to rotate. The rotation of the first gear 153 drives the transmission chain 155 to drive. The transmission chain 155 drives the second gear 155 and the third gear 156 to rotate. The rotation of the second gear 155 drives the first wheel 151 to rotate. The rotation of the third gear 156 drives the first roller brush 121 and the second roller brush 122 to rotate synchronously. The synchronous rotation of the first roller brush 121 and the second roller brush 122 achieves the cleaning of dust on the surface of the photovoltaic module.

[0045] like Figure 2 As shown, the cleaning robot 100 also includes a third wheel 157 and a wheel bracket 158. The third wheel 157 includes a third axle (not shown), which is coaxially connected to the first wheel 151 of the first power mechanism 150 by a connecting rod 159. One end of the wheel bracket 158 ​​is mounted to the rectangular frame 130, and the third wheel 157 is rotatably mounted to the other end of the wheel bracket 158.

[0046] like Figures 3-4 As shown, the cleaning robot 100 also includes a fourth wheel 160, which is rotatably mounted to the bottom of the first power mechanism 150 and the second power mechanism 160 of the elongated vehicle body 110. The central axis of the fourth wheel 160 is perpendicular to the central axis of the first wheel 151. While the fourth wheel 160 moves along the edge of the photovoltaic module, it also prevents the cleaning robot 100 from falling off the tilted photovoltaic module.

[0047] In application scenarios, for example, when the cleaning robot 100 moves on a flat photovoltaic module, the first power mechanism 150 and the second power mechanism 160 start synchronously. The first power mechanism 150 and the second power mechanism 160 drive the cleaning robot 100 to move on the photovoltaic module. When the first power mechanism 150 and the second power mechanism 160 start synchronously, the first wheel motor 152 drives the first power output shaft (not shown) to rotate. The rotation of the first power output shaft (not shown) drives the first gear 153 to rotate. The rotation of the first gear 153 drives the transmission chain 155 to drive the transmission, and the transmission chain 155 drives the second gear 155. The rotation of the third gear 156 drives the rotation of the second gear 155, which in turn drives the first wheel 151 to rotate. The rotation of the third gear 156 drives the first roller brush 121 and the second roller brush 122 to rotate synchronously. The synchronous rotation of the first roller brush 121 and the second roller brush 122 achieves the cleaning of dust on the surface of the photovoltaic module. When the cleaning robot 10 moves to the edge of the photovoltaic module, it controls the cleaning robot 100 to stop moving according to the data transmitted by the sensor 141. If a secondary cleaning of the photovoltaic module is required, the first power mechanism 150 and the second power mechanism 160 are activated. By controlling the rotation direction of the first power output shaft (not shown), the direction of travel of the cleaning robot 100 is controlled.

[0048] This application provides a cleaning robot, including a long, narrow body and two roller brushes. The long, narrow body includes two long sides and two short sides, with a first mounting plate and a second mounting plate respectively disposed on the two short sides. The long, narrow body is made of aluminum alloy, making it lightweight. The roller brushes are a first roller brush and a second roller brush. The first end of the first roller brush is rotatably mounted to the first mounting plate, and the first end of the second roller brush is rotatably mounted to the second mounting plate. The second ends of the first and second roller brushes are coaxially connected. The cleaning robot includes a first power mechanism and a second power mechanism, which enable the cleaning robot to move on a smooth panel. The cleaning robot has a simple structure, low manufacturing cost, and can meet the daily cleaning needs of ground power stations.
