Abstract
Description
Technical Field
[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, and in particular to a UAV spraying system. Background Technology
[0002] With the continuous development of modern construction and drone technology, painting operations have gradually shifted from traditional manual operation to automated drone painting. However, in existing drone painting systems, the cables or conduits used to deliver paint and power are connected to the drone body at one end and directly to the paint bucket or power supply box at the other end. This causes the cables or conduits to hang freely in the air during drone flight, making them prone to swaying and pulling on the drone, thus affecting the stability of the drone's flight. Furthermore, when the drone lands, the cables or conduits fall directly to the ground, requiring a significant amount of manpower for subsequent collection and handling, which severely impacts work efficiency and wastes labor costs.
[0003] The technical problem to be solved by this application is: to design a drone painting system that can constrain cables or conduits during drone painting without affecting the drone's flight. Utility Model Content
[0004] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a drone painting system that can constrain cables or conduits during drone painting without affecting the drone's flight.
[0005] The technical solution adopted by this utility model is as follows: a drone spraying system, including a drone, the drone is provided with a power transmission line and a paint tube that are detachably connected to each other at one end, a quick-release connector is provided between the power transmission line and the drone, a quick-release spring buckle is provided between the paint tube and the drone, and also includes a first electric winch for constraining and winding the power transmission line and a second electric winch for constraining and winding the paint tube.
[0006] In some implementations, the quick-release connector includes a plug connected to one end of a power line and a socket connected to a drone, the socket having a locking block that limits rotational connection thereto.
[0007] In some embodiments, the quick-release spring clip includes an interface end for connecting to one end of the paint tube, the interface end being provided with a spring clip for enabling quick disassembly of the paint tube.
[0008] In some implementations, a sealing ring is provided on the inner wall of the interface end.
[0009] In some embodiments, both the first and second electric winches include a motor and a drum connected to the motor drive, with the power transmission line and paint pipe wound on the drum respectively.
[0010] In some embodiments, the other end of the paint tube is provided with a detachably connected paint bucket.
[0011] In some implementations, the drone is also equipped with a robotic arm, which has grippers that are connected to it in a transmission manner.
[0012] This utility model has the following technical effects: By providing quick-release connectors and quick-release spring clips, it enables rapid disassembly and installation between the power transmission line and coating pipe and the drone, thereby improving the corresponding installation efficiency. Furthermore, it is equipped with a first electric winch and a second electric winch for constraining and winding the power transmission line and coating pipe. By using the first and second electric winches to constrain and wind up the power transmission line and coating pipe, the drone's flight status is not affected by the swaying of the power transmission line and coating pipe during operation. Moreover, when the drone lands, the first and second electric winches can automatically wind up the power transmission line and coating pipe, thus avoiding the need for manual storage and organization later. This improves work efficiency while significantly reducing corresponding labor costs. Attached Figure Description

Detailed Implementation
[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0018] Please see Figure 1-3This utility model provides a technical solution: a drone spraying system, including a drone 1, wherein the drone 1 is respectively provided with a power supply 2 and a paint tube 3 detachably connected to one end. In order to facilitate the installation between the power supply 2 and the paint tube 3 and the drone 1, a quick-release connector 6 is provided between the power supply 2 and the drone 1, and a quick-release spring clip 7 is provided between the paint tube 3 and the drone 1. The quick-release connector 6 includes a plug 60 connected to one end of the power supply 2 and a socket 61 connected to the drone 1. The socket 61 is provided with a locking block 62 that is rotatably connected to it. The quick-release spring clip 7 includes an interface end 70 for connecting to one end of the paint tube 3. The interface end 70 is provided with a spring clip 71 for quickly disassembling the paint tube 3. The inner wall of the interface end 70 is also provided with a sealing ring. By providing the quick-release connector 6 and the quick-release spring clip 7, the power supply 2 and the paint tube 3 can be quickly disassembled and installed with the drone 1, thereby improving the corresponding installation efficiency.
[0019] The system also includes a first electric winch 4 for restraining and winding the power transmission line 2 and a second electric winch 5 for restraining and winding the paint pipe 3. Both the first and second electric winches include a motor 8 and a drum 9 connected to the motor 8. The power transmission line 2 and the paint pipe 3 are pre-wound onto the drum 9 before being connected to the drone 1. The other end of the paint pipe 3 is detachably connected to the paint bucket 10, while the other end of the power transmission line 2 is connected to the power supply box. By having the first and second electric winches 4 and 5 respectively, and winding the power transmission line 2 and the paint pipe 3 onto their drums 9, when the drone 1 is in flight, as the drone 1's flight altitude increases, the operator can control the motor 8 to drive the drum 9 to rotate, thereby achieving the winding of the power transmission line... The power line 2 and the paint tube 3 are laid out. Since both the power line 2 and the paint tube 3 are wound by the drum 9, and the length of the power line 2 and the paint tube 3 laid out by the drum 9 is determined according to the flight altitude of the drone 1, the drum 9 acts as a traction constraint on the power line 2 and the paint tube 3 when the drone 1 is flying. This prevents the power line 2 and the paint tube 3 from hanging freely in the air. Therefore, the drone 1 will not be affected by the swaying of the power line 2 and the paint tube 3 during flight. When the drone 1 lands, the staff can control the motor 8 to drive the drum 9 to rotate and rewind the power line 2 and the paint tube 3, thus avoiding the need for manual storage and organization later. This improves work efficiency and greatly reduces the corresponding labor costs.
[0020] The drone 1 is equipped with a robotic arm 11 on its side wall. The robotic arm 11 is equipped with a gripper 12 that is connected to it for transmission. By having the robotic arm 11 drive the gripper 12 to move, it is possible to pick up and clean up the garbage attached to the outside of the curtain wall when the drone 1 cleans the curtain wall from high altitude.
[0021] The working principle of this utility model is as follows: By providing quick-release connectors 6 and quick-release spring clips 7, the power transmission line 2 and coating pipe 3 can be quickly disassembled and installed with the drone 1, thereby improving the installation efficiency. Furthermore, a first electric winch 4 and a second electric winch 5 are provided for constraining and winding the power transmission line 2 and coating pipe 3. By constraining and winding the power transmission line 2 and coating pipe 3 with the first electric winch 4 and the second electric winch 5 respectively, the drone 1 will not be affected by the swaying of the power transmission line 2 and coating pipe 3 during flight. When the drone 1 lands, the first electric winch 4 and the second electric winch 5 can automatically wind up the power transmission line 2 and coating pipe 3, thus avoiding the need for manual storage and organization later. This improves work efficiency and significantly reduces labor costs.
[0022] Finally, it should be noted that the above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
