Of course, in other embodiments, the steering gear 302 can also be installed on another steering gear, so that the nozzle 304 can be rotated at another angle to ensure the flexibility of spraying.

[0028] Furthermore, if Figure 4 As shown, a wind shield 306 is provided on the outside of the paint spray head assembly 3, and the wind shield 306 is provided with an opening just in front of the spray head 304 to facilitate the paint spraying of the spray head 304. In addition, a reinforcing rib 3061 is provided on the wind shield 306 to ensure the stability of the structure.

[0029] Specifically, the drone body 1 is a six-axis six-propeller drone, whose motor and electric regulator are fixed on the arm, and 32-inch blades are installed on the motor to provide lift for the entire drone system. The paint box 201 and the spray pump 202 are both located on the support plate 204 of the landing gear 101, making full use of the effective space of the drone. The maximum capacity of the paint box 201 is 30 kilograms. It has the characteristics of compact structure, large capacity, integrity, high strength, etc., which can meet the requirements of long-term spraying operations of drones. The power of the spray pump 202 is 350W, and the paint spraying rate is 1.1L / min. It can be remotely controlled within a range of 1 kilometer to meet various spraying needs.

[0030] In other embodiments, the battery 102, paint box 201 and spray pump 202 may be placed on the ground and connected to the components on the drone body through tethered cables and paint tubes, so that long-term spraying operations can be achieved.

[0031] The drone body 1 is provided with a drone battery 102, which is electrically connected to the spray pump 202 and the steering gear 302 to provide power. That is, the spray pump 202, the steering gear 302 and the drone share a set of batteries 102, and the drone battery 102 supplies power to the spray pump 202 and the steering gear 302, thereby making the overall structure simpler and lighter.

[0032] The spray pump 202 and the steering gear 302 are both connected to the remote control terminal (such as a remote control, not shown in the figure); the spray pump 202 can be remotely controlled by the remote control terminal, which is convenient for remote control during the spraying operation.

The visual sensor includes a camera for visual navigation, target recognition and processing to ensure real-time detection of the spraying effect and completion of more sophisticated path planning tasks during the completion of the spraying task. The liquid level sensor is installed in the paint box 201 to detect the remaining amount of paint to ensure early warning before the paint is exhausted. Accurate detection and control of the flight part and the spraying part are completed through the cooperation of multiple sets of sensors. The power part consists of six sets of brushless motors and propellers. Through real-time monitoring of the load part, the power of the power part can be accurately output to achieve stable flight. The power part of the equipment is equipped with redundancy to cope with safe flight under bad weather and high load conditions. During spraying, by monitoring and controlling the spraying process, the spraying parameters (liquid flow, spraying speed) can be monitored in real time and the spraying operation can be adjusted.

[0034] The utility model adopts a drone to avoid the traditional cumbersome process of personnel climbing up and setting up scaffolds, and uses a drone to fly directly and quickly to the target point for spraying operations, which not only greatly improves efficiency, but also is very safe, ensuring the safety of people and buildings themselves. In addition, due to the design of the adjustable paint spray head assembly 3, the direction of the spray head 304 can be controlled by the remote control.

The UAV body 1 is equipped with a flexible nozzle 304, which can spray wherever it flies. It is flexible and maneuverable, suitable for large-area and long-distance operations, improves work efficiency, and has no dead angles. The utility model organically combines flight and spraying, and opens up a broader market for the application scenarios of UAVs.
