Description

Technical Field

[0001] The present invention relates to the technical field of defect elimination of power grid equipment, and particularly relates to an unmanned aerial vehicle (UAV) wind-driven spraying device. Background Art

[0002] With the continuous development of power grid equipment, the need to protect power grid equipment is urgent. People need to regularly spray pesticides on plants under power equipment and power grid equipment to drive away pests and remove weeds, so as to prevent the weeds and pests from damaging the power grid equipment. Usually, people use a UAV to carry a storage tank filled with pesticides and fly to the spraying location to spray the plants.

[0003] The storage tanks on the existing UAVs have high costs and are difficult to disassemble, and cannot achieve the effect of "using one and replacing one". When the liquid medicine in the storage tank is used up, the user needs to stop the operation of the UAV wind-driven spraying device and refill the storage tank with the liquid medicine, resulting in a reduction in the working efficiency of the UAV wind-driven spraying device; at the same time, since the liquid medicine has certain toxicity, the user will increase the exposure time of the human body in the liquid medicine environment during the process of refilling the liquid medicine, causing certain harm to the human body and reducing the safety.

[0004] Therefore, it is urgent to design a UAV wind-driven spraying device to solve the above technical problems. Summary of the Invention

[0005] The purpose of the present invention is to provide a UAV wind-driven spraying device with low cost, and the container assembly can quickly and conveniently achieve "using one and replacing one", improving the working efficiency and safety performance of the UAV wind-driven spraying device.

[0006] To achieve the above object, the present invention adopts the following technical solutions:

[0007] The present invention provides a UAV wind-driven spraying device, including:

[0008] A UAV body;

[0009] A spraying assembly, which is arranged on the UAV body;

[0010] A container assembly, which is arranged on the UAV body. The container assembly includes a beverage bottle body, and a liquid medicine is contained in the beverage bottle body. The bottom of the beverage bottle body is communicated with the spraying assembly, and a concave portion is arranged at the bottom of the beverage bottle body. A water pipe quick connector is arranged on the concave portion, and the water pipe quick connector is communicated with the spraying assembly through a connecting pipe, and the liquid medicine can flow along the connecting pipe into the spraying assembly.

[0011] As an alternative technical solution of a drone wind-driven spraying device, the quick-connect water pipe joint includes a first fixing member and a second fixing member. The first fixing member is disposed inside the beverage bottle body and on the recessed portion. One end of the second fixing member is connected to the connecting pipe, and the other end of the second fixing member is threadedly connected to the first fixing member.

[0012] As an alternative technical solution of a drone wind-driven spraying device, the quick-connect water pipe joint includes a first sealing ring and a second sealing ring.

[0013] As an alternative technical solution of a drone wind-driven spraying device, the connecting pipe includes a hard pipe, a flexible pipe, and a connecting sleeve. The hard pipe and the flexible pipe are connected by the connecting sleeve. One end of the hard pipe away from the connecting sleeve is connected to the second fixing member, and one end of the flexible pipe away from the connecting sleeve is connected to the spraying assembly.

[0014] As an alternative technical solution of a drone wind-driven spraying device, the container assembly includes a mechanical timer and a bottle stopper. The bottle stopper is disposed at the bottle mouth of the beverage bottle body to block the bottle mouth. The mechanical timer is sleeved on the bottle mouth. The mechanical timer can adsorb the bottle stopper at a preset time so that the bottle stopper is separated from the bottle mouth and the beverage bottle body is in an open state.

[0015] As an alternative technical solution of a drone wind-driven spraying device, the mechanical timer includes a fixed seat, a rotating head, and a mechanical spring. The fixed seat is connected to the rotating head through the mechanical spring. A fixing ring is disposed on the fixed seat, and the fixing ring is sleeved on the bottle mouth.

[0016] As an alternative technical solution of a drone wind-driven spraying device, the rotating head extends a protruding arm, and a magnetic sheet is disposed on the protruding arm. A magnetic bead is disposed inside the bottle stopper. The rotating head drives the protruding arm to be able to rotate above the bottle mouth at a preset time so that the magnetic bead can be adsorbed by the magnetic sheet at a preset time, the bottle stopper is separated from the bottle mouth, and the beverage bottle body is in an open state.

[0017] As an alternative technical solution of a drone wind-driven spraying device, an accommodation space is disposed inside the bottle stopper, and the magnetic bead is disposed inside the accommodation space and can rotate freely inside the accommodation space.

[0018] As an alternative technical solution of the drone wind-driven spraying device, an iron ring is sleeved on the outer peripheral side of the bottle mouth. The magnetic bead can adsorb to the iron ring so that the bottle stopper plugs the bottle mouth, and the beverage bottle body is in a closed state. The adsorption force between the magnetic bead and the iron ring is less than the adsorption force between the magnetic bead and the magnetic sheet.

[0019] As an alternative technical solution of the drone wind-driven spraying device, the container assembly further includes a normally closed stopper, which is used to be clamped between the bottle stopper and the protruding arm so that the beverage bottle body is in a normally closed state.

[0036] To make the technical problems solved by the present invention, the technical solutions adopted and the achieved technical effects clearer, the technical solutions of the present invention will be further described below with reference to the accompanying drawings and through specific implementation manners.

[0037] In the description of the present invention, unless otherwise clearly defined and limited, the terms "connected", "connected to", and "fixed" shall be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0038] In the present invention, unless otherwise clearly defined and limited, the first feature being "above" or "below" the second feature may include the direct contact between the first and second features, or may include the situation where the first and second features are not in direct contact but in contact through other features between them. Moreover, the first feature being "above", "over", and "on top of" the second feature includes that the first feature is directly above and obliquely above the second feature, or merely means that the horizontal height of the first feature is higher than that of the second feature. The first feature being "under", "below", and "beneath" the second feature includes that the first feature is directly below and obliquely below the second feature, or merely means that the horizontal height of the first feature is lower than that of the second feature.

[0039] In the description of this embodiment, the orientation or positional relationships such as "above", "below", "left", and "right" are based on the orientation or positional relationships shown in the drawings, and are only for the convenience of description and simplifying the operation, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present invention. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0040] Such as Figures 1 - 5As shown in the figure, this embodiment provides an unmanned aerial vehicle (UAV) wind-driven spraying device, which mainly includes a UAV body 100, a spraying assembly 200, and a container assembly 300. Among them, the spraying assembly 200 is connected to the UAV body 100. The spraying assembly 200 includes a water wheel chamber 210, a containing chamber 220, a transverse drive system 230, and a longitudinal drive system 240. The water wheel chamber 210 is connected to the containing chamber 220. One end of the transverse drive system 230 passes through the containing chamber 220 and is placed inside the water wheel chamber 210. One end of the longitudinal drive system 240 passes through the containing chamber 220 and is connected with a centrifugal disk 2403, and the centrifugal disk 2403 communicates with the water wheel chamber 210. The container assembly 300 is connected to the UAV body 100. The container assembly 300 contains liquid medicine. The bottom of the container assembly 300 communicates with the water wheel chamber 210. The transverse drive system 230 can rotate to reduce the pressure in the water wheel chamber 210, so that the liquid medicine in the container assembly 300 flows into the water wheel chamber 210 and flows from the water wheel chamber 210 to the centrifugal disk 2403. The centrifugal disk 2403 sprays out the liquid medicine under the rotation of the longitudinal drive system 240.

[0041] Based on the above design, in this embodiment, the container assembly 300 is clamped on the UAV body 100 through a buckle 110. The container assembly 300 contains pre-packaged and adjusted liquid medicine, such as herbicide liquid medicine for tall plants and vines, and can also be paired with bird repellents, snake repellents, etc. Furthermore, it can realize the removal of weeds under power equipment and the expulsion of small animals under power equipment, so as to play a role in protecting power equipment. The container assembly 300 communicates with the water wheel chamber 210 on the spraying assembly 200 through a connecting pipe 400.

[0042] Specifically, as Figure 4 shown, the transverse drive system 230 in this embodiment includes a transverse axis 2301, transverse wind blades 2302, and a water wheel disk 2303. One end of the transverse axis 2301 passes through the containing chamber 220 and is connected to the water wheel disk 2303. The other end of the transverse axis 2301 is connected with transverse wind blades 2302. The wind flow caused by the rotation of the propeller blades of the UAV body 100 can blow the transverse wind blades 2302 to rotate. Further, water wheel blades 2304 are arranged on the water wheel disk 2303. The transverse wind blades 2302 can drive the transverse axis 2301 to rotate, so that the transverse axis 2301 drives the water wheel disk 2303 to rotate, and the water wheel blades 2304 stir and pressurize the liquid medicine. Furthermore, the transverse wind blades 2302 drive the transverse axis 2301 to rotate, the transverse axis 2301 drives the water wheel disk 2303 to rotate, and the water wheel disk 2303 forms a negative pressure (pressure less than the external atmospheric pressure) inside the water wheel chamber 210 during the rotation process. In this way, the liquid medicine in the container assembly 300 can be sucked into the water wheel chamber 210 under the pressure of the atmospheric pressure and the influence of gravity.

[0043] AsFigure 4 As shown, in this embodiment, the longitudinal drive system 240 includes a longitudinal axis 2401 and longitudinal blades 2402. One end of the longitudinal axis 2401 passes through the accommodation cavity 220 and is connected to the centrifugal disc 2403. The other end of the longitudinal axis 2401 is connected with the longitudinal blades 2402. The air flow caused by the rotation of the propeller blades of the UAV body 100 can blow the longitudinal blades 2402 to rotate. Further, the centrifugal disc 2403 includes an upper cover 2404, a lower cover 2405 and centrifugal blades 2406. The centrifugal blades 2406 are arranged on the lower cover 2405. The centrifugal blades 2406 are connected to the longitudinal axis 2401. The longitudinal axis 2401 can drive the centrifugal blades 2406 to rotate. The upper cover 2404 covers the centrifugal blades 2406. The upper cover 2404 and the lower cover 2405 jointly enclose a spraying chamber for accommodating the centrifugal blades 2406. And a liquid inlet 2407 is arranged on the upper end surface of the upper cover 2404, and a liquid outlet 2101 is arranged on the water wheel chamber 210. The liquid inlet 2407 and the liquid outlet 2101 are connected by a flexible pipe 260. It should be noted that the transverse axis 2301 and the longitudinal axis 2401 in this embodiment are eccentrically arranged in the accommodation cavity 220, that is, the rotations of the transverse axis 2301 and the longitudinal axis 2401 do not interfere with each other and do not affect each other.

[0044] When the propeller blades of the UAV body 100 rotate, the air flow generated can blow the longitudinal blades 2402 to rotate. Then, the longitudinal blades 2402 drive the longitudinal axis 2401 to rotate, and the longitudinal axis 2401 drives the centrifugal disc 2403 to rotate, so that the liquid medicine flowing from the water wheel chamber 210 to the centrifugal disc 2403 can be thrown out by the centrifugal blades 2406 in the centrifugal disc 2403. Under the action of centrifugal force, the liquid droplets of the liquid medicine can be atomized and spread around. Under the combined action of centrifugal force and the wind pressure of the UAV body 100, the liquid droplets can be accurately sprayed within the range of the vertical line of the UAV body 100, thereby realizing precise application of the liquid medicine. The flow direction of the liquid medicine can be referred to Figure 5 as shown.

[0045] Further, the distance between the upper cover 2404 and the lower cover 2405 in this embodiment is greater than the height of the centrifugal blades 2406. This enables the centrifugal blades 2406 to rotate flexibly in the spraying chamber, reducing the friction between the centrifugal blades 2406 and the upper cover 2404 and the lower cover 2405, and improving the reliability and stability.

[0046] Even further, as Figure 4 shown, in this embodiment, the centrifugal blades 2406 are arranged in multiple numbers, and each centrifugal blade 2406 is arc-shaped. The multiple centrifugal blades 2406 are arranged in an array with respect to the longitudinal axis 2401. This enables the liquid medicine to be evenly thrown out and improves the working efficiency of spraying the liquid medicine. Exemplarily, the number of the centrifugal blades 2406 can be set to 6, 7, 8, etc. This embodiment does not limit this.

[0047] As Figure 3 shown, the spraying assembly 200 in this embodiment includes a bridging arm 250. One end of the bridging arm 250 is connected to the UAV body 100, and the other end of the bridging arm 250 is movably connected to the water wheel chamber 210. The spraying assembly 200 includes a bolt 2501. The bolt 2501 connects the bridging arm 250 to the water wheel chamber 210, and the bridging arm 250 can rotate relative to the water wheel chamber 210. Specifically, the bridging arm 250 can rotate 180 degrees relative to the water wheel chamber 210, so that the user can adjust the angle of the spraying assembly 200 relative to the UAV body 100 by loosening the bolt 2501 before the UAV body 100 takes off, so that the spraying assembly 200 can effectively balance with the wind resistance.

[0048] Optionally, as Figure 1 shown, four spraying assemblies 200 are provided in this embodiment, and two bridging arms 250 are provided on each spraying assembly 200 to improve the stability of each spraying assembly 200. Of course, the operator can set other numbers of spraying assemblies 200 according to actual needs, such as setting them to 1, 2, or 3, etc. This embodiment does not limit this.

[0049] Compared with the prior art, the UAV wind-driven spraying device provided in this embodiment has a simple structure. Through the settings of the lateral drive system 230 and the longitudinal drive system 240, the UAV wind-driven spraying device can spray the liquid medicine without using the electric drive in the traditional technology, thereby reducing the weight of the UAV wind-driven spraying device, miniaturizing the device, and saving costs. At the same time, since the UAV wind-driven spraying device in the present invention reduces the electric drive device, the risk of the liquid medicine entering the electric drive device and causing a short circuit or even a battery explosion is avoided, thereby improving the safety performance of the UAV wind-driven spraying device.

[0050] As Figure 1 、 Figure 6 shown, in this embodiment, the container assembly 300 is arranged on the UAV body 100. The container assembly 300 includes a beverage bottle body 310. The beverage bottle body 310 contains liquid medicine. The bottom of the beverage bottle body 310 is communicated with the spraying assembly 200, and a recess 320 is provided at the bottom of the beverage bottle body 310. A water pipe quick connector 330 is provided in the recess 320. The water pipe quick connector 330 is communicated with the spraying assembly 200 through a connecting pipe 400, and the liquid medicine can flow into the spraying assembly 200 along the connecting pipe 400.

[0051] In this embodiment, a commercially available beverage bottle is selected as the beverage bottle body 310, which has a low cost, is easy to obtain, and the liquid medicine has no corrosive effect on the beverage bottle body 310. This enables the container assembly 300 to achieve the effect of "using a new one each time", saving costs while eliminating the step of filling the liquid medicine and improving the work efficiency of the user. The user can achieve the effect of quickly replacing the beverage bottle body 310 through the water pipe quick connector 330, avoiding the situation in the traditional technology where the user is exposed to the liquid medicine environment for a long time due to filling the liquid medicine, and reducing the risk of toxic harm of the liquid medicine to the user. Moreover, the setting of the recessed portion 320 facilitates the installation of the water pipe quick connector 330 and enables the beverage bottle body 310 to be stably placed on the drone body 100.

[0052] As Figures 6 - 7 shown, in this embodiment, the water pipe quick connector 330 includes a first fixing member 3301 and a second fixing member 3302. The first fixing member 3301 is disposed inside the beverage bottle body 310 and is disposed on the recessed portion 320. One end of the second fixing member 3302 is connected to the connecting pipe 400, and the other end of the second fixing member 3302 is threadedly connected to the first fixing member 3301. Optionally, the first fixing member 3301 is a nut and the second fixing member 3302 is a bolt, and the assembly of the water pipe quick connector 330 is realized through their threaded connection. In this way, when the user replaces the beverage bottle body 310, the user can conveniently disconnect the connection between the first fixing member 3301 and the second fixing member 3302, thereby enabling the replacement of the container assembly 300. And in this embodiment, a buckle 110 is provided on the drone body 100, and the beverage bottle body 310 of the container assembly 300 is snap-fitted on the buckle 110. The buckle 110 is made of a plastic material and has a certain ductility, so that when the user needs to replace the container assembly 300, the beverage bottle body 310 can be conveniently disassembled from the buckle 110, improving the work efficiency.

[0053] Furthermore, the water pipe quick connector 330 includes a first sealing ring 3303 and a second sealing ring 3304. The first sealing ring 3303 is disposed on the first fixing member 3301, and the second sealing ring 3304 is disposed on the second fixing member 3302. The settings of the first sealing ring 3303 and the second sealing ring 3304 can improve the sealing performance of the beverage bottle body 310 and prevent the liquid medicine from leaking. Both the first sealing ring 3303 and the second sealing ring 3304 can be made of a silicone material.

[0054] As Figure 1As shown in the figure, in this embodiment, the connecting pipe 400 includes a hard pipe 410, a flexible pipe 420, and a connecting sleeve 430. The hard pipe 410 and the flexible pipe 420 are connected through the connecting sleeve 430. One end of the hard pipe 410 away from the connecting sleeve 430 communicates with the second fixing member 3302, and one end of the flexible pipe 420 away from the connecting sleeve 430 communicates with the spraying assembly 200. Since the water pipe quick connector 330 cannot be docked with the flexible pipe 420, and the hard pipe 410 cannot achieve a large-angle change on the water wheel cavity 210 of the spraying assembly 200, therefore, the connecting pipe 400 in this embodiment adopts a segmented design, that is, the hard pipe 410 is connected to the water pipe quick connector 330, and the flexible pipe 420 is connected to the spraying assembly 200, so as to give full play to the respective advantages of the flexible pipe 420 and the hard pipe 410, and a connecting sleeve 430 is installed between the hard pipe 410 and the flexible pipe 420 to improve the sealing performance.

[0055] As Figure 6 , Figure 8 shown, in this embodiment, the container assembly 300 includes a mechanical timer 340 and a bottle stopper 350. The bottle stopper 350 is arranged at the bottle mouth of the beverage bottle body 310 and seals the bottle mouth. The mechanical timer 340 is sleeved on the bottle mouth, and the mechanical timer 340 can adsorb the bottle stopper 350 at a preset time, so that the bottle stopper 350 is separated from the bottle mouth, and the beverage bottle body 310 is in an open state. Optionally, the bottle stopper 350 in this embodiment is made of silica gel material to improve the sealing performance of the bottle stopper 350 to the bottle mouth.

[0056] Further, the mechanical timer 340 includes a fixed seat 3401, a rotating head 3402, and a mechanical spring. The fixed seat 3401 is connected to the rotating head 3402 through the mechanical spring. A fixing ring 3406 is arranged on the fixed seat 3401, and the fixing ring 3406 is sleeved on the bottle mouth. The rotating head 3402 extends out a protruding arm 3403, a magnetic sheet 3405 is arranged on the protruding arm 3403, a magnetic bead 3501 is arranged in the bottle stopper 350, and the rotating head 3402 drives the protruding arm 3403 to be able to rotate to directly above the bottle mouth at a preset time, so that the magnetic bead 3501 can be adsorbed by the magnetic sheet 3405 at a preset time, the bottle stopper 350 is separated from the bottle mouth, and the beverage bottle body 310 is in an open state. It should be noted that the working principle of the mechanical timer 340 in this embodiment is a prior art, that is, its working principle is the same as that of a common mechanical alarm clock on the market, and will not be elaborated here. A display screen is arranged on the rotating head 3402 in this embodiment, which is used to display the countdown time of the rotation of the rotating head 3402, so as to facilitate the user to observe the value of the preset time.

[0057] Exemplarily, the preset time can be 5 minutes, so that the user can, within the preset time, remotely control the drone body 100 to lift the drone body 100 carrying the spraying assembly 200 and the container assembly 300 and fly it above the place where the liquid medicine is to be sprayed, such as above farmland, shrubbery and other scenarios. Then, when the 5 minutes arrive, the protruding arm 3403 on the rotating head 3402 can rotate to directly above the bottle mouth, and at this time, the magnetic bead 3501 is magnetically adsorbed to the magnetic sheet 3405 on the protruding arm 3403, so that the bottle stopper 350 moves upward, thereby opening the bottle mouth by the bottle stopper 350, and enabling the liquid medicine in the beverage bottle body 310 to flow into the spraying assembly 200 under the action of gravity and atmospheric pressure.

[0058] Further, in this embodiment, a receiving space is provided in the bottle stopper 350, the magnetic bead 3501 is arranged in the receiving space, and the magnetic bead 3501 can freely rotate in the receiving space, thereby improving the reliability and stability of the magnetic bead 3501 being adsorbed by the magnetic sheet 3405, and avoiding the phenomenon that the magnetic bead 3501 gets stuck in the bottle stopper 350.

[0059] As Figure 6 shown, in this embodiment, an iron ring 360 is sleeved on the outer peripheral side of the bottle mouth. The magnetic bead 3501 can be adsorbed to the iron ring 360 to block the bottle mouth by the bottle stopper 350, and the beverage bottle body 310 is in a closed state; the adsorption force between the magnetic bead 3501 and the iron ring 360 is less than the adsorption force between the magnetic bead 3501 and the magnetic sheet 3405. When the mechanical timer 340 is within the preset time, for example, within 5 minutes, the protruding arm 3403 on the rotating head 3402 is not on the same vertical line as the bottle mouth, so that the magnetic sheet 3405 is adsorbed to the magnetic bead 3501, thereby enabling the magnetic bead 3501 to be adsorbed to the iron ring 360 on the beverage bottle body 310, so that the bottle stopper 350 can stably block the bottle mouth. At this time, a certain pressure difference is formed between the inside of the beverage bottle body 310 and the external atmospheric pressure, so that the liquid medicine cannot flow out. That is to say, at this time, the beverage bottle body 310 is in a closed state. When the protruding arm 3403 rotates to directly above the bottle mouth, since the adsorption force between the magnetic bead 3501 and the magnetic sheet 3405 is greater than the adsorption force between the magnetic bead 3501 and the iron ring 360, the magnetic bead 3501 is adsorbed by the magnetic sheet 3405, and the bottle stopper 350 moves upward, thereby opening the bottle mouth by the bottle stopper 350, and enabling the liquid medicine in the beverage bottle body 310 to flow into the spraying assembly 200 under the action of gravity and atmospheric pressure.

[0060] Compared with the prior art, the container component 300 in this embodiment has a simple structure, low cost, and is easy to obtain. By using a waste beverage bottle body 310 on the market, the effect of "using one and replacing one" of the container component 300 is achieved. That is, when the liquid medicine in the container component 300 is used up, the user can conveniently replace it with a new container component 300 filled with liquid medicine, thus saving the steps of filling the liquid medicine in the traditional technology, improving work efficiency while saving costs. The user can achieve the effect of quickly replacing the beverage bottle body 310 through the water pipe quick connector 330, avoiding the situation where the user is exposed to the liquid medicine environment for a long time due to filling the liquid medicine in the traditional technology, reducing the risk of toxic damage of the liquid medicine to the user, and improving the protection effect on the user.

[0061] Optionally, as Figure 6 shown, in this embodiment, the container component 300 further includes a normally closed plug 370, and the normally closed plug 370 is used to be clamped between the bottle stopper 350 and the protruding arm 3403 to keep the beverage bottle body 310 in a normally closed state. When the drone wind-driven spraying device is in the state of manual handling and transfer, in order to prevent the liquid medicine in the beverage bottle body 310 from flowing out, the user can insert the normally closed plug 370 between the protruding arm 3403 and the bottle stopper 350, so that the normally closed plug 370 can block the adsorption between the magnetic bead 3501 in the bottle stopper 350 and the magnetic sheet 3405 on the protruding arm 3403, thereby keeping the bottle stopper 350 blocking the bottle mouth all the time. The normally closed plug 370 is made of wood or silica gel material. Of course, the user can also use other materials to make the normally closed plug 370, and this embodiment does not make specific limitations on this.

[0062] The specific working principle of the drone wind-driven spraying device in this embodiment is as follows:

[0063] I. Preparation work:

[0064] First, the user installs the container component 300 filled with liquid medicine and the spraying component 200 on the drone body 100, and connects the container component 300 and the spraying component 200 through the connecting pipe 400. Then, the user can calculate the flight time required for the drone body 100 (such as 5 minutes) according to the distance between the drone wind-driven spraying device and the spraying location and the flight speed of the drone body 100, and then time this time through the mechanical timer 340, that is, rotate the rotating head 3402 to make the rotating head 3402 deflect by a certain angle, and then start a 5-minute countdown. (Of course, the user can rotate the rotating head 3402 to make the time counted down by the mechanical timer 340 slightly longer than 5 minutes, such as set to 6 minutes, so as to leave a margin for time error)

[0065] II. Takeoff work:

[0066] The user operates the remote controller to control the unmanned aerial vehicle (UAV) wind-driven spraying device to take off, so that the UAV wind-driven spraying device flies above the pre-spraying location. When the countdown of the mechanical timer 340 ends, the protruding arm 3403 on the rotating head 3402 rotates to directly above the bottle mouth. At this time, the magnetic bead 3501 is magnetically adsorbed to the magnetic sheet 3405 on the protruding arm 3403, causing the bottle stopper 350 to move upward, thereby opening the bottle mouth by the bottle stopper 350, and enabling the liquid medicine in the beverage bottle body 310 to flow into the spraying assembly 200 under the action of gravity and atmospheric pressure. At the same time, the air flow caused by the rotation of the propeller blades of the UAV body 100 can blow the transverse wind blade 2302 to rotate. The transverse wind blade 2302 can drive the transverse shaft 2301 to rotate, so that the transverse shaft 2301 drives the water wheel disc 2303 to rotate. During the rotation of the water wheel disc 2303, a negative pressure (pressure less than the external atmospheric pressure) is formed inside the water wheel cavity 210. In this way, the liquid medicine in the beverage bottle body 310 can be sucked into the water wheel cavity 210 under the pressure of the atmospheric pressure and the action of gravity, and finally flows into the centrifugal disc 2403 through the flexible connecting pipe 260 from the water wheel cavity 210. The air flow caused by the rotation of the propeller blades of the UAV body 100 can blow the longitudinal wind blade 2402 to rotate. The longitudinal wind blade 2402 drives the longitudinal shaft 2401 to rotate, and the longitudinal shaft 2401 drives the centrifugal disc 2403 to rotate, so that the liquid medicine flowing from the water wheel cavity 210 to the centrifugal disc 2403 can be thrown out by the blades in the centrifugal disc 2403. Under the action of centrifugal force, the liquid droplets of the liquid medicine can be atomized and spread around. Under the combined action of centrifugal force and the wind pressure of the UAV body 100, the liquid droplets can be accurately sprayed within the range of the vertical line of the UAV body 100, thus realizing precise pesticide application.
