Description

A drone spraying device with good stability Technical Field

[0001] This utility model relates to the technical field of drone spraying devices, specifically to a drone spraying device with good stability. Background Technology

[0002] With the rapid development of the drone industry, more and more drones are being used in daily life and production, especially in the field of high-altitude spraying technology, where the application of drones is becoming increasingly important.

[0003] Most current drone painting devices include a loading device and a drone. The drone is mounted on the loading device and drives the loading device to fly in order to spray paint or other coatings onto the target object. For example, a drone painting device disclosed in authorization announcement number CN221965779U and a high-altitude drone painting efficiency enhancement device and drone disclosed in authorization announcement number CN119018350B both belong to this type of drone painting device.

[0004] The problem with the aforementioned drone painting device is that while the loading device improves the stability of the drone during flight to some extent, the overall stability remains poor under windy conditions, such as outdoor spraying operations, resulting in low painting quality. Therefore, this invention proposes a drone painting device with improved stability to address these technical problems. Summary of the Invention

[0005] The purpose of this invention is to overcome the defects in the existing technology and provide a drone spraying device with good stability. In use, the frame with wheels is bound to one end of the frame by a traction rope and rolled against the side of the object to be sprayed. The drone drives the frame to rise or fall sequentially along the traction rope to achieve spraying processing of the corresponding area of ​​the side to be sprayed. This significantly improves the stability of the spraying components on the frame during spraying operations. It is applicable even in windy outdoor conditions, ensuring good spraying quality and high efficiency. The overall structure design is simple, the manufacturing and implementation are highly feasible, and it is very practical.

[0006] To achieve the above objectives, the technical solution of this utility model is to design a drone spraying device with good stability, including a frame, a drone mounted on the top of the frame, several wheels rotatably mounted on the left side of the frame, a spraying component installed inside the frame, and the nozzles on the spraying component facing the left side of the frame. The frame is provided with a wire hole, and also includes an upper slide rail assembly mounted on the top of the object to be sprayed and a lower slide rail assembly mounted on the bottom of the object to be sprayed. A traction rope that can move horizontally along the side of the object to be sprayed is connected between the upper slide rail assembly and the lower slide rail assembly. The frame is slidably connected to the traction rope through the wire hole, and the several wheels roll against the side of the object to be sprayed.

[0007] This utility model discloses a drone spraying device with good stability. In use, the frame with wheels is bound to one end of the frame by a traction rope and rolled against the side of the object to be sprayed. The drone drives the frame to rise or fall sequentially along the traction rope to achieve spraying processing of the corresponding area of ​​the side to be sprayed. This significantly improves the stability of the spraying components on the frame during spraying operations. It is applicable even in windy outdoor conditions, ensuring good spraying quality and high efficiency. The overall structure design is simple, the manufacturing and implementation are highly feasible, and it is very practical.

[0008] A preferred technical solution is that the lower end face of the drone has a two-degree-of-freedom gimbal with a through-hole. The spraying assembly further includes a spraying rod, a paint tank, and an air pump. The frame contains a support platform, and the paint tank is mounted on the upper surface of the support platform. The air inlet of the paint tank is connected to the air outlet of the air pump via a hose. The spraying rod is inserted and fixed inside the through-hole on the two-degree-of-freedom gimbal, with the nozzle mounted on its left end and its right end connected to the outlet of the paint tank. The spraying rod's insertion and mounting on the two-degree-of-freedom gimbal on the lower end face of the drone allows for seamless spraying within a confined space, thus improving the spraying quality of the drone spraying device.

[0009] A further preferred technical solution is that the spraying assembly also includes a wind shield sleeved and installed on the left end of the spraying rod. The wind shield has a trumpet-shaped structure, with the larger diameter end of the wind shield facing the left side of the frame. The nozzle is located inside the wind shield. The wind shield protects the nozzle and can concentrate the paint sprayed from the nozzle even in windy outdoor conditions, helping to further ensure the spraying quality of the UAV spraying device of this utility model.

[0010] A further preferred technical solution includes a wheel assembly comprising a wheel 1 rotatably mounted on the lower left side of the frame and a wheel 2 rotatably mounted on the upper left side of the frame, and a wheel 3 rotatably mounted on the upper right side of the frame, with the upper edges of both wheel 2 and wheel 3 extending above the upper side of the frame. When spraying paint onto the middle and lower ends of the vertical sides of the object to be painted, the left side of the frame rolls into contact with the corresponding vertical sides via wheel 1 and wheel 2; when spraying paint onto the upper ends of indoor vertical walls, the upper side of the frame rolls into contact with the indoor roof via wheel 2 and wheel 3, thereby significantly improving the applicable operating scenarios of this UAV spraying device.

[0011] A further preferred technical solution includes having two of each of the three wheels: wheel one, wheel two, and wheel three. Two wheel ones correspond to the two corner positions at the lower end of the left side of the frame, two wheel twos correspond to the two corner positions at the upper end of the left side of the frame, and two wheel threes correspond to the two corner positions at the upper end of the right side of the frame. All three wheels are omnidirectional wheels. Having two of each wheel improves the stability of rolling contact between the left side of the frame and the vertical side of the object to be painted. Similarly, it improves the stability of the upper side of the frame when it rolls into contact with the indoor roof via wheel two and wheel three.

[0012] A further preferred technical solution is that the frame is constructed by welding together four rods (first type) along the horizontal X-axis, four rods (second type) along the horizontal Y-axis, and four rods (third type) along the vertical Z-axis. Pins are vertically fixed to the left ends of the two top rods, and the threaded holes are located on these pins. The frame structure design is simple and reasonable, ensuring the smooth fabrication and implementation of the UAV painting device of this invention.

[0013] A further preferred technical solution is that the frame is further welded with several rods located in the vertical Z-axis direction, and the outer periphery of the support platform is welded and fixed to the lower ends of the rods.

[0014] A further preferred technical solution includes a centrally located cross-shaped platform for the drone. The two-degree-of-freedom gimbal is mounted through the central hole of the cross-shaped platform. Each of the four lower arms of the cross-shaped platform has a lug plate with a through-hole. The cross-shaped platform is then mounted through these through-holes to the right end of one of the two rods at the top of the frame. The drone is mounted to the two rods at the top of the frame through the through-holes on the lower lug plates. This simple installation method ensures ease of mounting and dismounting the drone from the frame.

[0015] A further preferred technical solution is that the drone is connected to a mobile power source via a cable. This further ensures the flexibility of the drone painting device during painting operations.

[0016] A further preferred technical solution includes an upper slide rail assembly comprising a slide rail, several sliders slidably mounted on the slide rail, and a drive component for driving the sliders to move along the slide rail. The lower slide rail assembly has the same structure as the upper slide rail assembly. The two ends of the traction rope are fixed to a corresponding set of sliders on both the upper and lower slide rail assemblies. The sliders on the slide rail assembly are driven by the drive component, improving the ease of operation when the frame moves horizontally during spraying operations.

[0017] The advantages and beneficial effects of this utility model are as follows:

[0018] 1. This utility model provides a drone spraying device with good stability. In use, the frame with wheels is bound to one end of the frame by a traction rope and rolled against the side of the object to be sprayed. The drone drives the frame to rise or fall sequentially along the traction rope to achieve spraying processing of the corresponding area of ​​the side to be sprayed. This significantly improves the stability of the spraying components on the frame during spraying operations. It is applicable even in windy outdoor conditions, ensuring good spraying quality and high efficiency. The overall structure design is simple, the manufacturing and implementation are highly feasible, and the device is highly practical.

[0019] 2. The spraying rod is installed on the two-degree-of-freedom gimbal on the lower end face of the drone, which can achieve spraying without dead angles in the confined space, thus helping to improve the spraying quality of the drone spraying device of this utility model.

[0020] 3. The spraying assembly also includes a wind shield fitted onto the left end of the spraying rod. The wind shield has a horn-shaped structure, with its larger diameter end facing the left side of the frame. The nozzle is located inside the wind shield. The wind shield protects the nozzle and, even in windy outdoor conditions, helps to concentrate the paint sprayed from the nozzle, further ensuring the spraying quality of the UAV spraying device of this invention.

A wheel 3 is rotatably mounted on the upper right side of the frame, and the upper edge surfaces of both wheel 2 and wheel 3 extend to the upper side of the frame. When spraying paint on the middle and lower ends of the vertical side of the object to be painted, the left side of the frame rolls into contact with the corresponding vertical side through wheel 1 and wheel 2. When spraying paint on the upper end of an indoor vertical wall, the upper side of the frame rolls into contact with the indoor roof through wheel 2 and wheel 3, thereby significantly improving the applicable operating scenarios of this UAV spraying device.

[0022] 5. Two wheels are provided for each of the three types of wheels, which improves the stability of rolling contact between the left side of the frame and the vertical side of the object to be sprayed.

The two ends of the traction rope 5 are fixed to a set of corresponding sliders 3-2 on the upper slide rail assembly 3 and the lower slide rail assembly 4. Specifically, the driving component can be a stepper motor. The sliders on the slide rail assembly are driven by the driving component, which improves the ease of operation when the frame moves horizontally during the spraying operation.

[0047] The working principle of this utility model of a drone spraying device with good stability is as follows:

[0048] Step 1: When in use, fix the slide rail 3-1 of the upper slide rail assembly 3 on the top of the object to be sprayed 14 on the side corresponding to the side to be sprayed. Similarly, fix the slide rail 3-1 of the lower slide rail assembly 4 on the bottom of the object to be sprayed 14 or on the ground on the side corresponding to the side to be sprayed.

[0049] Step 2: Thread one traction rope 5 through the wire hole on the front pin 1-8 at the top of the frame 1, and thread the other traction rope 5 through the wire hole on the rear pin 1-8 at the top of the frame 1. Fix the upper end of the traction rope 5 to a slider 3-2 on the upper slide rail assembly 3 and the lower end to a slider 3-2 on the lower slide rail assembly 4. Use the two traction ropes 5 to make the two wheels 1-5 and two wheels 1-6 on the left side of the frame 1 roll and tension against the lower end of the side of the object to be sprayed 14 (see Figures 9-10).

[0050] Step 3: Start the working switch through the controller, and the air pump 8 will start to inflate the paint tank 10, and the nozzle 12 will start to spray paint on the corresponding area of ​​the side of the object to be sprayed 14. At the same time, the power supply 6 will supply power to the drone 2 to support flight. The frame 1 will rise continuously under the flight driving force of the drone 2, and the left side of the frame 1 will gradually roll and rise from bottom to top along the corresponding area of ​​the side of the object to be sprayed 14 through two wheels 1-5 and two wheels 1-6.

[0051] Step 4: After the area is sprayed, turn off the air pump 8 through the controller, and at the same time start the movement displacement button through the controller. Then the stepper motor on the upper slide rail assembly 3 and the stepper motor on the lower slide rail assembly 4 will drive the corresponding slider 3-2 to move along the slide rail 3-1 to the next area. Repeat step 3 to spray the next area.

[0052] When spraying the upper side of the object to be sprayed 14, the frame 1 is removed from the tow rope 5; the controller controls the drone 2 to take off to the designated height, the controller starts the air pump 8, and the nozzle 12 begins to spray paint on the upper side of the object to be sprayed 14. At the same time, the controller can also control the drone 2 to move horizontally along the upper side of the object to be sprayed to complete the spraying process on all the upper sides of the object to be sprayed 14. For example, when spraying an indoor wall, the controller controls the drone 2 to take off until the wheels 1-6 and 1-7 roll into contact with the roof. The controller starts the air pump 8, and the nozzle 12 begins to spray paint on the upper side of the object to be sprayed 14. At the same time, the controller can also control the drone 2 to move horizontally in a circumferential direction along the upper side of the object to be sprayed to complete the circumferential spraying process on all the upper sides of the object to be sprayed.

[0053] This utility model discloses a drone spraying device with good stability. In use, the frame with wheels is bound to one end of the frame by a traction rope and rolled against the side of the object to be sprayed. The drone drives the frame to rise or fall sequentially along the traction rope to achieve spraying processing of the corresponding area of ​​the side to be sprayed. This significantly improves the stability of the spraying components on the frame during spraying operations. It is applicable even in windy outdoor conditions, ensuring good spraying quality and high efficiency. The overall structure design is simple, the manufacturing and implementation are highly feasible, and it is very practical.

[0054] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
