Photovoltaic power generation has been widely used in all walks of life. After the photovoltaic system has been used for a period of time, there will inevitably be dust accumulation on the surface of the photovoltaic panels. In order to ensure the power generation efficiency, the surface cleaning of the photovoltaic panels is essential. Traditional cleaning methods mainly rely on workers to use various equipment for cleaning, which has low cleaning efficiency and is limited by the site environment. Some places are difficult for workers to clean effectively, and may even bring certain risks to workers.

[0034] Photovoltaic power generation is a power generation method that collects solar energy by installing photovoltaic panels on photovoltaic brackets and then converts solar energy into electrical energy. Photovoltaic power generation has been widely used in all walks of life. After the photovoltaic system has been used for a period of time, there will inevitably be dust accumulation on the surface of the photovoltaic panels. In order to ensure the power generation efficiency, the surface cleaning of the photovoltaic panels is essential. Traditional cleaning methods mainly rely on workers to use various equipment for cleaning, which has low cleaning efficiency and is limited by the site environment. Some places are difficult for workers to clean effectively, and may even bring certain risks to workers.
[0035] In order to save labor cleaning costs and clean photovoltaic panels more safely, the relevant technology uses an automatic cleaner to move back and forth on the surface of the photovoltaic panel to clean the dust on the photovoltaic panel. The traction rope in the traction device is connected to the automatic cleaner, and the automatic cleaner is driven to move back and forth by winding the traction rope or unwinding the traction rope. The traction rope is suspended on one side of the photovoltaic panel. During the process of winding the traction rope or unwinding the traction rope, the suspended traction rope is easy to shake, causing the automatic cleaner to deviate from the preset moving path, resulting in part of the surface of the photovoltaic panel cannot be cleaned, thereby making the cleaning efficiency of the automatic cleaner low.
[0036] In view of the above problems, an embodiment of the present application provides a traction device, which aims to solve the technical problem that the traction rope and the automatic cleaner are prone to shaking under external disturbances.
[0037] In order to illustrate the technical solution of the present application, a description is given below in conjunction with specific drawings and embodiments.
[0038] Please refer to Figure 1 , Figure 2 and Figure 4 An embodiment of the present application provides a traction device, including a support assembly 1, a guide assembly 2 and a drive assembly 3.
[0039] The bracket assembly 1 is used to connect the photovoltaic panel 5; the guide assembly 2 is arranged on the bracket assembly 1, and the driving assembly 3 includes a driving member 31, a traction rope 32 and a winding member 33. The winding member 33 is rotatably arranged on the bracket assembly 1, and the winding member 33 is located on the side of the guide assembly 2 away from the photovoltaic panel 5. The traction rope 32 runs through the guide assembly 2, and one end of the traction rope 32 is fixed on the winding member 33, and the other end of the traction rope 32 is used to connect with the automatic cleaner 6. The driving member 31 is used to drive the winding member 33 to rotate to reel in or unreel the traction rope 32.
[0040] In the traction device provided by the present application, one end of the traction rope 32 is fixed on the winding member 33, and the other end of the traction rope 32 is used to connect with the automatic cleaner 6. The driving member 31 is used to drive the winding member 33 to rotate to reel in or unreel the traction rope 32. When the traction rope 32 is reeled in, the automatic cleaner 6 will move on the surface of the photovoltaic panel 5 and approach the winding member 33 under the drive of the traction rope 32. When the traction rope 32 is unreeled, the automatic cleaner 6 will move on the surface of the photovoltaic panel 5 and move away from the winding member 33 under the action of its own gravity, so that the automatic cleaner 6 cleans the surface of the photovoltaic panel 5. Since the traction device includes the guide assembly 2, and the traction rope 32 runs through the guide assembly 2, the traction rope 32 is not easy to shake during the process of reeling in or unreeling the traction rope 32, so that the automatic cleaner can move along the preset moving path, so that the entire surface of the photovoltaic panel 5 can be cleaned, thereby improving the cleaning efficiency of the automatic cleaner.
[0041] Please refer to Figure 1 The photovoltaic panel 5 is tilted, and the automatic cleaner 6 is mounted on the photovoltaic panel 5; the traction rope 32 is connected to the automatic cleaner 6, and when the traction device is not working, the length of the unwound traction rope 32 remains unchanged, which can prevent the automatic cleaner 6 from moving downward relative to the photovoltaic panel 5; when the winding member 33 rotates and rewinds the traction rope 32, the unwound traction rope 32 becomes shorter, and the traction rope 32 drives the automatic cleaner 6 to move upward relative to the photovoltaic panel 5; when the winding member 33 rotates and unwinds the traction rope 32, the unwound traction rope 32 becomes longer, and the automatic cleaner 6 moves downward relative to the photovoltaic panel 5 under the action of its own gravity. The guide assembly 2 can support and limit the traction rope 32 to prevent the traction rope 32 from shaking.
[0042] Please refer to Figure 3 In some embodiments, the guide assembly 2 includes a guide pulley 21, which is rotatably disposed on the bracket assembly 1, and a guide groove 211 is provided on the guide pulley 21, the depth direction of the guide groove 211 is along the radial direction of the guide pulley 21, and the traction rope 32 is located in the guide groove 211.

[0046] Through the above-mentioned arrangement, the bottom of the guide groove 211 can contact and support the traction rope 32 to prevent the traction rope 32 from being suspended above the guide pulley 21, thereby preventing the traction rope 32 from shaking; and when the traction rope 32 is wound or unwound, the traction rope 32 can drive the guide pulley 21 to roll, so that the traction rope 32 can be wound or unwound more stably and smoothly.
[0047] Please refer to Figure 3 In some embodiments, the width of the guide groove 211 gradually increases in a direction from the groove bottom of the guide groove 211 to the groove opening of the guide groove 211 .
