[0001] The utility model relates to the technical field of building engineering construction especially relates to a high altitude spraying system based on unmanned aerial vehicle group operation. BACKGROUND

[0002] In order to beautify the appearance of buildings and protect them from the erosion of the natural environment, spraying engineering has become an indispensable part.

[0003] However, in the actual operation process, it is found that most of the unmanned aerial vehicles on the market are mainly designed for loading and transporting raw materials. This means that when these unmanned aerial vehicles complete a spraying task, they must return to the ground to reload raw materials, and after reloading, the unmanned aerial vehicles need to fly back to the original working position. Secondly, these unmanned aerial vehicles need to be manually cleaned before spraying operation, and manually dried after spraying operation. This process not only consumes time, but also is inefficient, which undoubtedly increases the time cost and labor cost of the project. SUMMARY

[0004] In order to overcome the shortcomings of the prior art, the technical problem to be solved by the utility model is to provide a high altitude spraying system based on unmanned aerial vehicle group operation. The spraying system is composed of two parts of ground machine and unmanned aerial vehicle group. The time for the unmanned aerial vehicle to frequently return to the ground to supplement the spraying raw materials during the spraying operation is saved, and manual cleaning of the surface of the spraying area and manual acceleration of the drying and curing of the coating are no longer needed, thereby significantly improving the overall efficiency of the spraying operation.

[0005] To achieve the above purpose, the utility model provides a high altitude spraying system based on unmanned aerial vehicle group operation, which comprises: a ground machine chassis part for realizing forward movement of the device; a ground machine main part installed on the ground machine chassis part, which comprises a spraying hose, a drying unmanned aerial vehicle power supply line and a polishing unmanned aerial vehicle power supply line; a polishing unmanned aerial vehicle part comprising a first unmanned aerial vehicle connected with the polishing unmanned aerial vehicle power supply line and a polisher installed below the first unmanned aerial vehicle, used for cleaning the polishing work surface before spraying operation; a spraying unmanned aerial vehicle part comprising a second unmanned aerial vehicle and a spray gun connected with the spraying hose, the spray gun being installed below the second unmanned aerial vehicle and rotating through a driving mechanism, used for omnidirectional spraying operation on the part to be sprayed; and a drying unmanned aerial vehicle part comprising a third unmanned aerial vehicle connected with the drying unmanned aerial vehicle power supply line and a blower installed below the third unmanned aerial vehicle, used for drying treatment of the coating.

[0006] Preferably, the ground machine main part further comprises a mobile power supply, and the drying unmanned aerial vehicle power supply line and the polishing unmanned aerial vehicle power supply line are connected with the mobile power supply.

[0007] Further, the top of the ground machine body part is provided with a wireless charging platform for wireless charging of the spraying unmanned aerial vehicle part.

[0008] Preferably, the ground machine body part further comprises a storage tank A and a storage tank B filled with two different spraying raw materials, the storage tank A and the storage tank B are connected with an air compressor through electromagnetic valves, and the spraying hose is connected with the air compressor.

[0009] Further, the driving mechanism comprises a first servo motor installed below the second unmanned aerial vehicle, a second servo motor connected with the first servo motor through a vertically arranged first coupling, and a flange disc connected with the second servo motor through a horizontally arranged second coupling; the spray gun is fixed on the flange disc through a profile and an angle code.

[0010] Preferably, the air blower is provided with an air inlet filter for filtering impurities in the air.

[0011] Further, the ground machine chassis part comprises a load-bearing steel plate, two first tires installed at the bottom rear of the load-bearing steel plate, and two second tires installed at the bottom front of the load-bearing steel plate; the two first tires are connected with a driving motor through a transmission shaft, and the two second tires are connected with two bearings through a front axle.

[0012] Further, the ground machine body part comprises a load-bearing steel tube welded on the load-bearing steel plate from bottom to top, and the load-bearing steel tube constitutes a frame of the ground machine body part.

[0013] Compared with the prior art, the high-altitude spraying system based on unmanned aerial vehicle group operation has at least the following beneficial effects:

[0014] 1. The ground machine directly delivers spraying raw materials to the unmanned aerial vehicle through a pipeline, which eliminates the need for manual loading of paint, thereby greatly saving time and improving the work efficiency of the unmanned aerial vehicle. The unmanned aerial vehicle can continuously perform spraying operations in the air without frequent interruptions, thereby improving the continuity and efficiency of the operation.

[0015] 2. The spraying system supports remote control through a computer, which means that the staff can operate from a safe location away from the operation site, thereby greatly reducing the direct demand for manpower. This remote control method not only improves the convenience of operation, but also ensures the safety of the staff and avoids the risks that may be caused by high-altitude operation.

[0016] 3. The spraying system has high adaptability and can be applied to various different operation scenarios. Whether it is the surface spraying of a viaduct, the surface painting of a large windmill, or other high-altitude operation scenarios, the system can flexibly cope with them to ensure the smooth progress of the spraying operation.

[0017] 4. The unmanned aerial vehicle moves smoothly during spraying operations, and the direction control is accurate, which makes the sprayed surface more uniform. The flight stability of the unmanned aerial vehicle is guaranteed, so the spraying effect is more ideal, and the problem of uneven spraying caused by unstable operation is avoided.

[0018] 5. Compared with traditional manual spraying operations, using unmanned aerial vehicles for spraying operations can significantly save costs. This not only reflects in reducing labor demand, but also reflects in improving spraying efficiency and operation quality, thereby reducing overall operation costs and improving economic benefits.

[0019] 6. The device uses wireless charging technology, which significantly reduces many limitations compared to traditional wired charging methods. Through wireless charging, the device can achieve completely unmanned control operation, thereby significantly reducing labor costs. Specifically, wireless charging technology makes the device no longer dependent on fixed power sockets or cable connections. This convenient charging method not only improves the flexibility of the device, but also reduces the risk of equipment damage caused by frequent plugging and unplugging. Therefore, the application of wireless charging technology makes the device more efficient and convenient in actual use, and can significantly reduce labor costs in the long-term operation process.

[0020] 7. The device is designed with a structure that can freely swing in the horizontal and vertical planes at the connection of the unmanned aerial vehicle spraying pipe and the nozzle part. This unique design allows the nozzle to perform all-around spraying operations, greatly improving the flexibility and coverage of the spraying. Specifically, the nozzle can not only rotate in the horizontal direction, but also swing up and down in the vertical direction, making it easy to handle various complex spraying environments. For example, when spraying roofs, corners, and other hard-to-reach areas, the nozzle can adjust the angle flexibly to ensure uniform spraying and no dead angles. This all-around spraying capability makes the device highly practical and efficient in actual application, and can meet the spraying needs in various complex scenarios.

[0021] 8. The polishing unmanned aerial vehicle of the device can polish and remove impurities from the spraying site before the spraying unmanned aerial vehicle operates, removing impurities such as burrs, dust, rust, and loose rust on the surface of the substrate, creating clean surface conditions for subsequent spraying. At the same time, it improves the flatness and eliminates particles, roughness, and unevenness on the workpiece coating surface, thereby enhancing the adhesion of the coating, making the coating more firmly attached to the substrate and less likely to fall off.

[0022] 9. The drying unmanned aerial vehicle of the device can dry the coating after the spraying unmanned aerial vehicle operation, uniformly blows dry to make the paint form a uniform film on the surface, avoids the sagging phenomenon caused by the local paint being too thick and drying not in time, ensures the flatness and aesthetics of the coating, and can prevent dust, impurities and the like from being adsorbed on the surface of the undried paint, and reduce the pollution to the coating.
