Description

Technical Field

[0001] The utility model belongs to the technical field of snow-clearing devices, and in particular relates to a snow-clearing drone for photovoltaic modules. Background Art

[0002] A search of the existing technology revealed a Chinese patent for "A UAV Snow-Cleansing Device," with publication number "CN208184089U." This patent primarily benefits from the device's ability to be used in a variety of snow-clearing scenarios, particularly rooftops and high-voltage power lines, without being restricted by specific use scenarios. Furthermore, the drone platform allows for remote snow-clearing from a safe location, reducing the risk of human snow-clearing at heights like rooftops. The speed reduction device is threadedly connected to the broom mounting head, allowing for easy replacement when the broom wears out or needs to be replaced, allowing for multiple uses.

[0003] However, the structure of this device is relatively simple and it is difficult to apply it to cleaning relatively inclined or uneven scene surfaces, such as photovoltaic panels, greenhouses or pointed-roof houses. The cleaning broom on the rotating shaft of this device is fixed with bolts. Due to the limitation of the bolt thread connection, it is difficult to adjust the buffer in real time according to the inclination of the snow-clearing surface, so that its snow-clearing range is limited to cleaning relatively horizontal planes, which has certain limitations. Utility Model Content

By providing a buffer mechanism and utilizing the elasticity of a spring, the drone can drive a number of brushes through a rotating drum to adapt to the inclined surface of the photovoltaic panel. Without affecting the rotation of the rotating drum, the slider is driven to slide and buffer in a rectangular slide groove, and the brushes are rotated in conjunction with the rotating mechanism to complete adaptive snow clearing, thereby solving the problem of difficulty in adjusting the buffer in real time according to the inclination of the snow-clearing surface.

[0027] See also Figure 1-5 As shown, the utility model is a photovoltaic module snow-clearing drone, comprising a housing 1, on which a buffer mechanism 2 and a rotating mechanism 3 are provided;

[0028] The buffer mechanism 2 includes a buffer component and a flip component. The buffer component includes several rotating drums 21 arranged on the shell 1. The inner walls of the several rotating drums 21 are provided with rectangular chute 22. The inner walls of the several rectangular chute 22 are slidably connected with sliders 23. The sides of the several sliders 23 that are close to each other are fixedly connected to the connecting shaft 24. The sides of the several sliders 23 that are close to each other are fixedly connected to springs 25. The ends of the several springs 25 that are close to each other are fixedly connected to the inner walls of the rectangular chute 22. The outer walls of the several rotating drums 21 are fixedly connected to several brushes 26. The flip assembly includes several supporting frames 27 arranged on the outer wall of the shell 1, the inner walls of several supporting frames 27 are rotatably connected to the outer wall of the rotating drum 21, the outer walls of several supporting frames 27 are fixedly connected to the hinge blocks 28, the outer walls of several hinge blocks 28 are hinged to the connecting blocks 29, and the top surface of the shell 1 is provided with several limiting grooves 210. The inner walls of several limiting grooves 210 are slidably connected to the limiting blocks 211. The top ends of several limiting blocks 211 are hinged to the inner walls of several connecting blocks 29, and the outer wall of the connecting shaft 24 is rotatably connected to the inner wall of the supporting frame 27.

[0029] By setting up the buffer mechanism 2, the elasticity of the spring 25 is utilized. The drone can drive several brushes 26 through the rotating drum 21 to adapt to the inclined surface of the photovoltaic panel. Without affecting the rotation of the rotating drum 21, it drives the slider 23 to slide and buffer in the rectangular slide groove 22, and cooperates with the rotating mechanism 3 to rotate several brushes 26 to complete adaptive snow clearing. It is not only suitable for horizontal planes but also can adapt to a variety of relatively inclined and uneven surfaces to perform snow clearing, thereby improving the practicality of the device.

[0030] The rotating mechanism 3 includes a driving assembly and a universal assembly. The driving assembly includes a motor 31 fixedly connected to the inner wall of the shell 1. The output end of the motor 31 is fixedly connected to the first rotating shaft 32. The outer wall of the first rotating shaft 32 is fixedly connected to the first bevel gear 33. The inner wall of the shell 1 is rotatably connected to several second bevel gears 34. Several second bevel gears 34 are all meshed with the first bevel gear 33. The universal assembly includes second rotating shafts 35 that are all fixedly connected to the inner walls of several second bevel gears 34. The ends of the several second rotating shafts 35 that are away from each other extend to the outer wall of the shell 1 and are fixedly connected to the first hinge fork 36. The inner walls of several first hinge forks 36 are rotatably connected to cross connecting blocks 37. The ends of several connecting shafts 24 that are close to each other are fixedly connected to the second hinge fork 38. The inner walls of several second hinge forks 38 are rotatably connected to the top and bottom ends of the cross connecting block 37. The top surface of the shell 1 is fixedly connected to a fixing column 39.

[0031] By setting up the rotating mechanism 3, it is possible to use the motor 31 to drive several rotating drums 21 to rotate, drive the brushes 26 to sweep snow from the surface of the photovoltaic panel, and use the first hinge fork 36, the cross connecting block 37 and the second hinge fork 38 to cooperate with each other. When the rotating drum 21 is tilted, the rotating drum 21 can still be driven to rotate through the connecting shaft 24, ensuring that the device can sweep snow smoothly, further improving the practicality of the device.

[0032] A specific application of this embodiment is as follows: by setting a buffer mechanism 2, the device is fixed or suspended under the drone through a fixed column 39, the drone drives the device to move to the surface of the photovoltaic panel that needs to be cleared of snow, and the driving device descends so that the brushes 26 contact the photovoltaic panel. Due to the contact with the inclined surface of the photovoltaic panel, the force is applied to the drum 21 through the brushes 26, and the limit block 211 is driven to slide in the limit groove 210 by the hinged connection of the hinge block 28 and the connecting block 29 through the supporting frame 27, so that the drum 21 drives the second hinge fork 38 to flip around the cross connecting block 37 through the connecting shaft 24 to adapt to the inclination of the photovoltaic panel surface. Under the action of the force, the slider 23 is driven to slide in the rectangular slide 22, and the spring 25 is compressed. The slider 23 and the rectangular slide 22 are rectangular, which is convenient for cooperating with the rotating mechanism 3 to drive the drum 21 to rotate through the rectangular limit. Under the elastic force of the spring 25, the brushes 26 on the drum 21 are driven to contact the surface of the photovoltaic panel. The rotating mechanism 3 drives the drum 21 to rotate, and the brushes 26 are used to clean the surface of the photovoltaic panel. The receiving frame 27 is shorter than the brush 26, so that the brushes 26 will hit the receiving frame 27 when rotating, and a small amount of snowflake residue that may be stuck on the brushes 26 after snow sweeping can be knocked off, ensuring that the brushes 26 are relatively clean when clearing snow. The elasticity of the spring 25 is utilized, and the drone can drive the brushes 26 to adapt to the inclined surface of the photovoltaic panel through the rotating drum 21. Without affecting the rotation of the rotating drum 21, the slider 23 is driven to slide and buffer in the rectangular slide 22, and the rotating mechanism 3 is cooperated with the rotating brushes 26 to complete the adaptive snow sweeping. It is not only suitable for horizontal planes but also adaptable to a variety of relatively inclined and uneven surfaces to perform snow sweeping, thereby improving the practicality of the device.

[0033] By setting the rotating mechanism 3 and cooperating with the buffer mechanism 2 to complete the adaptation scene, the driving motor 31 drives the first bevel gear 33 to rotate through the first rotating shaft 32. Since the plurality of second bevel gears 34 are all engaged with the first bevel gear 33, the rotation of the first bevel gear 33 drives the plurality of second bevel gears 34 to rotate synchronously, and the plurality of second bevel gears 34 drive the second rotating shaft 35 to rotate. The second rotating shaft 35 drives the second rotating shaft 35 to rotate. A first hinge fork 36, a cross connecting block 37 and a second hinge fork 38 are provided, which are a simple universal shaft structure. When the rotating drum 21 in the adaptive buffer mechanism 2 is tilted, it can still be adjusted by The connecting shaft 24 drives the drum 21 to rotate to clean relatively uneven scene surfaces such as photovoltaic panels. Multiple drums 21 are arranged around the outer shell 1, so that the drone can cope with various scenes without self-adjusting steering, which is convenient for personnel operation. The motor 31 is used to drive several drums 21 to rotate, driving the brush 26 to sweep snow from the surface of the photovoltaic panel, and the first articulated fork 36, the cross connecting block 37 and the second articulated fork 38 cooperate with each other. When the drum 21 is tilted, the drum 21 can still be driven to rotate by the connecting shaft 24 to ensure that the device can sweep snow smoothly, further improving the practicality of the device.
