Technical Field

[0001] The invention belongs to the technical field of photovoltaic equipment, and in particular relates to a device for removing dirt from the surface of a photovoltaic component by utilizing natural wind. Background Art

[0002] At present, photovoltaic modules are also called solar cell modules. Solar cell modules are composed of high-efficiency crystalline silicon solar cells, ultra-white cloth-textured tempered glass, EVA, transparent TPT backplane and aluminum alloy frame. They have the characteristics of long service life and strong mechanical resistance to external pressure. At present, the surface of Taineng photovoltaic modules needs to be cleaned after a period of use.

[0003] However, the existing surface cleaning is generally done manually or with large mechanical equipment, which consumes a lot of electricity and water resources, is labor-intensive, and causes a lot of water waste. Photovoltaic modules are generally installed at high places, and in areas with strong winds, natural wind cannot be used to achieve the cleaning function.

[0004] Therefore, in view of the shortcomings of the above-mentioned scheme in actual production and implementation, it has been revised and improved. At the same time, in the spirit and concept of seeking excellence, with the assistance of professional knowledge and experience, and after many ingenuity and experiments, the present invention was created. Hereby, a device for cleaning dirt on the surface of photovoltaic components using natural wind is provided to solve the problem. Summary of the invention

[0019] After adopting the above technical solution, the beneficial effects of the present invention are: 1. The blades are driven by wind to rotate the cam, and the cooperation between the cam, the second elastic component and the moving plate drives the moving plate to move back and forth along the fourth support frame. The moving plate drives the wiping component to clean the surface of the photovoltaic module in combination with the liquid. The moving plate drives the first mounting frame to move along the third water pipe to control the intermittent opening of the drainage hole, thereby reducing the consumption of water resources and improving the rational use of energy. 2.

The first air guide tube 46 is similar to a chimney and has an upward suction force on the gas. Combined with the rotation of the cleaning brush 39 in the first cavity 41, the circulation of the gas is accelerated, impurities in the box 37 are brought out, and the cleaning effect is improved.

[0036] Example 6: Figures 1 to 4As shown, a second support frame 2 is welded to the first support frame 1, and a controller 3 and a wind speed detection mechanism 4 are installed on the second support frame 2 by bolts and nuts. The wind speed detection mechanism 4, the pumping component 6, the automatic detection mechanism 22, and the electric control valve are electrically connected to the controller 3. The wind speed detection mechanism 4, the pumping component 6, the automatic detection mechanism 22, and the electric control valve are intelligently controlled by the controller 3. When the wind speed detection mechanism 4 detects that the wind force reaches the set value, the pumping component is controlled to work through the controller 3. When the automatic detection mechanism 22 detects a signal, the pumping component is controlled to pause through the controller 3.

[0037] The working principle of the present invention is as follows: the electric control valve on the first water pipe 7 is opened, the electric control valve on the fourth water pipe 24 is closed, and the water pump 6 is started to supply water to the liquid storage tank 18 through the water hose 20. The solution in the liquid storage tank 18 gradually increases. When the liquid storage tank 18 moves downward along the photovoltaic module, the electric control valve on the fourth water pipe 24 is opened, and the liquid is sprayed on the surface of the photovoltaic module through the drainage hole 25 on the third water pipe 23 to wash the surface of the photovoltaic module. At this time, the water pump 6 continues to supply liquid to the liquid storage tank 18. The amount of liquid added in the liquid storage tank 18 is the same as the amount of liquid discharged. When the liquid storage tank 18 moves downward, the total weight remains unchanged. When the liquid storage tank 18 moves upward, the electric control valve on the first water pipe 7 is closed, and the water pump 6 is closed at the same time. The solution in the liquid storage tank 18 is discharged through the drainage hole 25 on the third water pipe 23 under the action of gravity, so that the total weight of the liquid storage tank 18 is reduced. The wind drives the blade 31 to rotate, and the blade 31 drives the cam 30 to rotate through the second rotating shaft 29. The cam 30 pushes the movable plate 32 to move in the direction of the second elastic component 33 and squeezes the second elastic component 33. The movable plate 32 drives the wiping component 36 to move in the direction of the second elastic component 33 through the first mounting frame 35. During the movement of the first mounting frame 35, the water seepage hole 50 is aligned with the drainage hole 25, and part of the drainage hole 25 is exposed between two adjacent wiping components 36. A part of the solution in the liquid storage tank 18 enters the wiping component 36, and a part is directly sprayed on the surface of the photovoltaic module, thereby cleaning the photovoltaic module. The components are flushed, and as the cam 30 rotates, the rebound force of the second elastic component 33 pushes the movable plate 32 to move away from the second elastic component 33, and the movable plate 32 drives the first mounting frame 35 to reset. At this time, the water seepage hole 50 is misaligned with the drainage hole 25, and the first mounting frame 35 blocks all the drainage holes 25 to prevent the solution from being discharged. The movable plate 32 is driven to move back and forth along the fourth support frame 26 through the cooperation of the cam 30, the second elastic component 33 and the movable plate 32, and the movable plate 32 drives the first mounting frame 35 to move along the third water pipe 23 to control the intermittent opening of the drainage hole 25; When the weight of the liquid in the liquid storage tank 18 is greater than the counterweight 11, the first sliding block 21 is driven by the liquid storage tank 18 to slide downward along the third support frame 8, and the counterweight 11 is driven to rise along the third support frame 8. When the liquid in the liquid storage tank 18 is discharged, the weight of the liquid in the liquid storage tank 18 is less than the counterweight 11, the first sliding block 21 is driven by the counterweight 11 to slide upward along the third support frame 8, so that the wiping component 36 can automatically rise and fall along the photovoltaic component, thereby improving the rational use of energy and reducing energy consumption, and at the same time driving the wiping component 36 to move at a uniform speed to improve the wiping effect.
