Description

Technical Field

[0001] The present application relates to the technical field of unmanned spraying devices, and in particular to a high-altitude UAV spraying efficiency enhancement device and a UAV. Background Art

[0002] In the fields of building exterior wall repair, large-scale facility maintenance, etc., the demand for using drones for high-altitude spraying operations has gradually become prominent. This efficient and safe method has brought revolutionary changes to traditional manual or hanging basket spraying.

[0003] At present, the general spraying device is to use a drone to drive an automatic spray gun to move to the construction site, and then start the automatic spray gun, which sprays the paint on the construction site, thereby easily improving the spraying efficiency.

[0004] However, because the rotation of the drone's own blades generates a large wind field, the automatic spray gun is affected by the wind force when it is opened for spraying operations, and the sprayed paint will be blown away by the wind generated by the drone itself, resulting in a large amount of waste of spray paint. Summary of the invention

[0005] In order to improve the utilization rate of spray paint, the present application provides a high-altitude UAV spray efficiency enhancement device and a UAV.

[0006] On the one hand, the present application provides a high-altitude drone spraying efficiency enhancement device, which adopts the following technical solution:

[0007] A high-altitude unmanned aerial vehicle spraying efficiency enhancement device, comprising:

[0008] A fuselage, wherein a plurality of propeller blades are arranged uniformly around a vertical axis of the fuselage, and the propeller blades are rotatably connected to the top of the fuselage;

[0009] A spraying assembly, arranged on the fuselage and used for spraying paint;

[0010] A collecting component is arranged on the spraying component and is used to collect the paint dripping during spraying;

[0011] Offsetting components, including:

[0012] A ducted fan, wherein the ducted fan is fixedly connected to the fuselage;

[0013] A wind shield, the wind shield is fixedly connected to the fuselage and is located on the spray assembly, one end of the wind shield is open, and the open end is arranged toward the flight direction of the fuselage; wherein the wind shield is used to generate a wind curtain to resist the wind field interference generated by the rotation of the UAV's own blades;

[0014] An air duct pipe, two ends of which are respectively connected to the duct fan and the wind hood.

[0015] By adopting the above technical solution, when the fuselage moves to the designated position, the duct fan supplies air to the wind hood through the duct pipe, and the wind hood blows air above the spray assembly to produce a wind curtain, which counteracts the wind field generated by the drone itself. Then, the spray assembly sprays the designated position, thereby effectively preventing the wind field generated by the drone from affecting the paint sprayed from the nozzle. During the spraying process, the collecting assembly collects the paint dripping during spraying to prevent paint waste, thereby improving the spraying efficiency and paint utilization rate.

[0016] Optionally, the opening end of the wind shield is duckbill-shaped, and the width direction of the wind shield is arranged parallel to the plane where the blades are located.

[0017] By adopting the above technical solution, the duckbill-shaped narrowing design can enhance the concentration and speed of the airflow, forming a more stable and powerful wind curtain, which can more effectively resist the wind field interference caused by the rotation of the drone blades. This directional wind curtain helps to maintain stable air flow in the spraying operation area, thereby easily reducing the impact of airflow turbulence on the spraying effect, and thus easily improving the spraying efficiency.

[0018] Optionally, the spraying assembly includes:

[0019] A nozzle, the nozzle is fixedly connected to the fuselage and is located below the wind shield;

[0020] An automatic spray gun, the automatic spray gun is fixedly connected to the fuselage, and the input end of the automatic spray gun is connected to an external storage tank;

[0021] A spray pipe, wherein the spray pipe is fixedly connected to the fuselage, and two ends of the spray pipe are respectively connected to the input end of the nozzle and the output end of the automatic spray gun.

[0022] By adopting the above technical solution, paint is supplied to the automatic spray gun through an external storage tank, and the automatic spray gun transports the paint to the nozzle through the spray pipe. Under the action of pressure, the paint is sprayed from the nozzle. By combining the precise position setting of the nozzle and the precise control of the automatic spray gun, precise control of the spraying trajectory and paint distribution is achieved, thereby reducing deviations and waste in the spraying process, and further improving the uniformity and consistency of the coating.

[0023] Optionally, the collection component includes:

[0024] The collecting box has an open top and a baffle fixedly connected to the open end, the baffle and the collecting box form a feed inlet, the collecting box is connected to a discharge pipe, and the discharge pipe is provided with a valve;

[0025] A wetting portion, disposed on the collection box and used to increase the humidity of the paint in the collection box;

[0026] The stirring part is arranged in the collecting box and is used for stirring the coating.

[0027] By adopting the above technical scheme, during the spraying process, part of the paint accumulates at the nozzle mouth, and the paint drips into the collection box through the feed port. Due to the strong wind at high altitude, the small amount of paint in the collection box is easy to dry up, and the infiltration part increases the humidity of the paint in the collection box to prevent the paint from drying up. After accumulating for a period of time, the stirring part stirs the paint in the collection box. The appropriate humidity and uniform mixing state help to extend the shelf life of the paint and reduce the failure of the paint due to drying, agglomeration, etc., so that it is easy to recycle the paint, thereby improving the utilization rate of the paint.

[0028] Optionally, the wetting portion includes:

[0029] An infrared sensor is fixedly connected to the side wall of the collection box and is located at the feed inlet of the collection box;

[0030] A controller, fixedly connected to the collection box and electrically connected to the infrared sensor;

[0031] A spray nozzle, fixedly connected to the baffle plate and located at the feed inlet of the collection box;

[0032] A water tank, fixedly connected to the collection tank and connected to the spray nozzle via a connecting pipe;

[0033] The water pump is connected in series to the connecting pipe and is electrically connected to the controller, and the controller is used to control the start and stop of the water pump.

[0034] By adopting the above technical solution, when the paint passes through the feed port, the infrared sensor outputs a displacement signal between the inner wall of the collection box and the baffle to the controller. The controller responds to the displacement signal output by the infrared sensor and controls the water pump to start. The water pump draws water from the water tank and transports it to the spray nozzle through the connecting pipe. The spray nozzle sprays water mist onto the inner wall of the collection box. The water flow flushes the inner wall of the collection box, which can prevent the paint from drying on the inner wall of the collection box. By timely increasing the humidity of the paint, the waste of paint caused by drying is reduced, making it easy to recycle the paint, thereby improving the utilization rate of the paint.

[0035] Optionally, the stirring unit includes:

[0036] The guide plate is arc-shaped, and one end of the guide plate is fixedly connected to the inner wall of the collecting box near the feed inlet;

[0037] A rotating plate, which is L-shaped and rotatably connected to the inner wall of the collection box, wherein the curved end of the rotating plate is located between the guide plate and the inner wall of the collection box;

[0038] A spring, one end of which is fixedly connected to the inner wall of the collection box, and the other end of which is fixedly connected to the rotating plate, wherein the spring is in a stretched state in an initial state;

[0039] A first induction block, fixedly connected to the curved end of the rotating plate;

[0040] A second induction block is fixedly connected to the guide plate and electrically connected to the controller, wherein when the compression amount of the spring is at a limit value, the first induction block abuts against the second induction block;

[0041] A motor, fixedly connected to the baffle and electrically connected to the controller;

[0042] The stirring rod is coaxially fixedly connected to the output shaft of the motor and is located in the collecting box.

[0043] By adopting the above technical solution, the paint drips onto the inner wall of the collection box through the feed port, flows along the inner wall of the collection box, flows through the guide plate and enters the rotating plate. When the paint accumulates to a set amount, the spring is squeezed, the compression amount of the spring increases, the spring accumulates elastic force, the rotating plate rotates, and the paint is poured to the bottom of the collection box;

[0044] When the rotating plate rotates, the sensing block 1 abuts against the sensing block 2, and the sensing block 2 outputs a sensing signal to the controller. The controller controls the output shaft of the motor to rotate, and the output shaft of the motor drives the stirring rod to rotate. The stirring rod stirs the paint, which can prevent the paint from static stratification, thereby improving the mixing efficiency.

[0045] Optionally, the nozzle is an adaptive nozzle.

[0046] By adopting the above technical solution, the adaptive nozzle can monitor and adjust the spraying parameters in real time through the built-in intelligent control system, and can accurately control the spraying amount of paint, avoiding waste and excessive use of paint, thereby helping to reduce the cost of spraying operations and easily reducing the impact on the environment.

[0047] Optionally, a fixing clamp is fixedly installed between the air duct pipe and the spray pipe.

[0048] By adopting the above technical solution, a stable connection between the air duct pipe and the spray pipe is ensured, thereby easily preventing the pipe from loosening or falling off due to vibration or external force impact during flight, thereby improving the stability of the device.

[0049] Optionally, threads are provided at both ends of the spray pipe, and the two ends of the spray pipe are threadedly connected to the input end of the nozzle and the output end of the automatic spray gun respectively through the threads.

[0050] By adopting the above technical solution, the threaded connection design makes the installation and disassembly process simple and quick. The operator can quickly connect the nozzle and automatic spray gun to the spray pipe, or replace and repair them as needed, thereby improving work efficiency.

[0051] On the other hand, the present application provides a drone, comprising the above-mentioned high-altitude drone spraying efficiency enhancement device.

[0052] By adopting the above technical solutions, the UAV can cover a large area in a short time due to its high-altitude flight capability and the optimization of the spraying efficiency enhancement device, thereby significantly improving the efficiency of the spraying operation.

[0053] In summary, the present application includes at least one of the following beneficial technical effects:

[0054] By setting up ducted fans, wind hoods and air ducts, the wind curtain counteracts the wind field generated by the drone itself, thereby effectively preventing the wind field generated by the drone from affecting the paint sprayed from the nozzle, thereby improving the spraying efficiency and paint utilization rate;

[0055] By setting the nozzle, automatic spray gun wind cover and spray pipe, the precise position setting of the nozzle and the precise control of the automatic spray gun are combined to achieve precise control of the spray trajectory and paint distribution, thereby reducing the deviation and waste in the spraying process, and thus improving the uniformity of the coating;

The guide plate 431 is arc-shaped, and one end is fixedly connected to the inner wall of the collecting box 41 near the feed inlet. The guide plate 431 and the inner wall of the collecting box 41 form a groove-shaped space, and the open end is arranged toward the bottom of the collecting box 41.

[0079] Reference Figure 3 and Figure 4 The rotating plate 432 is L-shaped and is rotatably connected to the inner wall of the collecting box 41.

[0082] When in use, during the spraying process, part of the paint accumulates at the nozzle 31, and the paint drips from the feed port to the inner wall of the collection box 41. The infrared sensor 421 detects the dripping of the paint, and the infrared sensor 421 outputs a displacement signal between the inner wall of the collection box 41 and the baffle 411 to the controller 422.
