[0002] With the development of microelectronics technology, unmanned aerial vehicles have increasingly come into people's view. At present, the unmanned aerial vehicle cleaning devices on the market are mostly used for cleaning buildings or solar panels. A water-carrying mechanism is installed below the unmanned aerial vehicle to transport the cleaning liquid, and the cleaning liquid is sprayed on the building or solar panel through a preset spraying device for cleaning. However, the current water-carrying mechanism generally only includes a water tank and a mounting bracket for connecting to the unmanned aerial vehicle. The mounting bracket is fixedly installed at the bottom of the unmanned aerial vehicle body, and the water tank is connected to an external spraying device through a connecting hose. However, as the water level continuously drops, the inside of the water tank gradually approaches a vacuum state, resulting in that it is not easy for the spraying device to suck out the water in the water tank; in addition, most current cleaning liquids are generally concentrated type and need to be diluted with water in a certain proportion before use. At present, before loading the cleaning liquid into the water-carrying mechanism of the unmanned aerial vehicle, it is necessary to first use other containers or equipment to dilute the concentrated cleaning liquid, and then pour it into the water tank for loading, which is time-consuming and laborious.

The air inlet pipe 4 is fixedly arranged on one side of the water tank 1, and one end of the air inlet pipe 4 penetrates through the water tank 1 and is arranged inside the water tank 1. The fixing bracket 5 is fixedly arranged inside the air inlet pipe 4. One end of the fixing rod 6 is fixedly connected to the fixing bracket 5, and the other end penetrates through the fixing bracket 5 and is fixedly connected to the rubber sealing sheet 7. A conical groove 8 is provided at one end of the air inlet pipe 4, and the rubber sealing sheet 7 fits with the conical groove 8. A first air intake groove 9 is provided on the fixing bracket 5. The stirring mechanism includes a driving shaft 10, a rotating shaft 11, stirring blades 12, a connecting plate 13 and a fixing mechanism. The rotating shaft 11 is rotatably arranged inside the water tank 1. The stirring blades 12 are fixedly connected to the rotating shaft 11. One end of the driving shaft 10 is fixedly connected to the rotating shaft 11, and the other end penetrates through the water tank 1 and is fixedly connected to the connecting plate 13. A handle 14 is provided at one end of the connecting plate 13 away from the driving shaft 10. A viewing window 26 is provided on one side of the water tank 1, and a scale line 27 is provided on the viewing window 26. The fixing mechanism includes a limiting sleeve 28 and a limiting rod 29. The limiting rod 29 is slidably arranged inside the handle 14. The limiting sleeve 28 is fixedly arranged on one side of the water tank 1, and the limiting rod 29 is slidably and non-rotatably arranged inside the limiting sleeve 28. A connecting screw 30 is provided at one end of the limiting rod 29 away from the limiting sleeve 28. A connecting nut 31 is rotatably arranged on the handle 14, and the connecting nut 31 is threadedly sleeved outside the connecting screw 30.

[0031] In this embodiment, the water tank 1 is filled with cleaning liquid. The sealing seat 16 and the liquid inlet pipe 15 are fitted together, and the first connecting sleeve 17 is threadedly sleeved outside the liquid inlet pipe 15 to complete the fixation of the sealing seat 16. The connecting nut 31 is rotated. Due to the cooperation of the limiting rod 29 and the limiting sleeve 28, the limiting rod 29 cannot rotate. Therefore, rotating the connecting nut 31 can drive the connecting screw 30 to move outwards until the limiting rod 29 moves out of the limiting sleeve 28. At this time, the handle 14 can be held to drive the drive shaft 10 to rotate, and then drive the rotating shaft 11 and the stirring blades 12 to rotate to stir the cleaning liquid in the water tank 1 to make it evenly diluted. After dilution, the handle 14 and the limiting sleeve 28 are aligned, and the connecting nut 31 is rotated to drive the connecting screw 30 to move inwards, and the limiting rod 29 is inserted into the limiting sleeve 28 to complete the fixation of the handle 14. The liquid outlet pipe 3 on the water tank 1 is pre-connected to an external spraying device. The drone takes off and sprays and cleans the building or the solar panel through the spraying device. The external spraying device pumps out the water in the water tank 1. At this time, a negative pressure state is formed in the water tank 1, and a certain gap is formed between the deformed rubber sealing sheet 7 and the conical groove 8. External air can enter the water tank 1 through the first air inlet groove 9 to restore the pressure in the water tank 1, which is convenient for the spraying device to continue to discharge the cleaning liquid in the water tank 1.

[0032] Please refer to Figures 1-5 , as an implementation manner of the feeding mechanism: The feeding mechanism includes a liquid inlet pipe 15, a sealing seat 16, and a first connecting sleeve 17. The air inlet pipe 4 is inclined and arranged on one side of the water tank 1, and the bottom end of the air inlet pipe 4 penetrates through the water tank 1. The first connecting sleeve 17 is rotatably and non-slidingly sleeved outside the sealing seat 16, and the first connecting sleeve 17 is threadedly connected to the liquid inlet pipe 15. The sealing seat 16 is provided with a first conical surface 18, and the liquid inlet pipe 15 is provided with a second conical surface 19 that cooperates with the first conical surface 18. The exhaust mechanism includes a connecting rod 20, a limiting plate 21, a second connecting sleeve 22, and a push rod 23. The limiting plate 21 is fixedly sleeved outside the connecting sleeve, and the limiting plate 21 is in contact with one end of the air inlet pipe 4. One end of the push rod 23 is fixedly connected to the connecting rod 20, and the other end slidably penetrates through the first air inlet groove 9. The second connecting sleeve 22 is threadedly sleeved outside the air inlet pipe 4, and a limiting ring 24 that cooperates with the limiting plate 21 is provided at the end of the second connecting sleeve 22 away from the push rod 23. The limiting plate 21 is provided with a second air inlet groove 25.

[0033] More specifically, when it is necessary to pour in new cleaning liquid and water, at this time, rotate the first connecting sleeve 17 to drive the sealing seat 16 to be detached from the liquid inlet pipe 15. Insert the push rod 23 into the liquid inlet pipe 15, and pass the push rod 23 through the first air inlet groove 9 until the push rod 23 pushes the rubber sealing sheet 7 to deform, so that there is a certain gap between it and the conical groove 8. At this time, the limiting plate 21 fits with the air inlet pipe 4. Sleeve the second connecting sleeve 22 outside the limiting plate 21, and thread-connect the second connecting sleeve 22 and the air inlet pipe 4 until the limiting ring 24 fits with the limiting plate 21 to fix the limiting plate 21. At this time, pour water and cleaning liquid into the water tank 1 through the liquid inlet pipe 15. The air in the water tank 1 is discharged through the air inlet pipe 4, the first air inlet groove 9 and the second air inlet groove 25. After the water injection is completed, detach the exhaust mechanism from the air inlet pipe 4.

[0034] In summary, when the overall device is in use or operation: The water tank 1 is filled with cleaning liquid. Fit the sealing seat 16 and the liquid inlet pipe 15, and thread the first connecting sleeve 17 outside the liquid inlet pipe 15 to complete the fixation of the sealing seat 16. Rotate the connecting nut 31. Since the limiting rod 29 and the limiting sleeve 28 cooperate, the limiting rod 29 cannot rotate. Therefore, rotating the connecting nut 31 can drive the connecting screw 30 to move outwards until the limiting rod 29 moves out of the limiting sleeve 28. At this time, hold the handle 14 and drive the drive shaft 10 to rotate, thereby driving the rotating shaft 11 and the stirring blades 12 to rotate to stir the cleaning liquid in the water tank 1 to make it evenly diluted. After dilution, align the handle 14 with the limiting sleeve 28 and rotate the connecting nut 31 to drive the connecting screw 30 to move inwards and insert the limiting rod 29 into the limiting sleeve 28 to complete the fixation of the handle 14. The liquid outlet pipe 3 on the water tank 1 is pre-connected to an external spraying device. The drone takes off and sprays and cleans the building or solar panels through the spraying device. The external spraying device pumps out the water in the water tank 1. At this time, a negative pressure state is formed in the water tank 1, the rubber sealing sheet 7 deforms and a certain gap is formed between it and the conical groove 8, and external air can enter the water tank 1 through the first air inlet groove 9 to restore the pressure in the water tank 1, facilitating the spraying device to continue to discharge the cleaning liquid in the water tank 1.

[0035] When new cleaning liquid and water need to be poured in, the first connecting sleeve 17 is rotated to drive the sealing seat 16 to be removed from the liquid inlet pipe 15, and the push rod 23 is inserted into the liquid inlet pipe 15, and the push rod 23 is passed through the first air inlet groove 9 until the push rod 23 pushes the rubber sealing sheet 7 to deform, so that a certain gap exists between it and the conical groove 8. At this time, the limit plate 21 and the air inlet pipe 4 fit together, and the second connecting sleeve 22 is sleeved outside the limit plate 21, and the second connecting sleeve 22 and the air inlet pipe 4 are threadedly connected until the limit ring 24 and the limit plate 21 fit together, and the limit plate 21 is fixed. At this time, water and cleaning liquid are injected into the water tank 1 from the liquid inlet pipe 15, and the air in the water tank 1 is discharged through the air inlet pipe 4, the first air inlet groove 9 and the second air inlet groove 25. When the water filling is completed, the exhaust mechanism is removed from the air inlet pipe 4.

[0036] In all the schemes mentioned above, the connection between two parts can be selected according to actual conditions by welding, bolt and nut matching connection, bolt or screw connection or other well-known connection methods, which are not described here one by one. In the above, all fixed connections are preferably welded. Although the embodiments of the utility model have been shown and described, it can be understood by ordinary technicians in this field that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the utility model. The scope of the utility model is defined by the attached claims and their equivalents.
