An ultrasonic insect control system combining air and ground operation

Abstract

This invention provides an air-ground combined ultrasonic pest control system, belonging to the field of pest control technology. It includes a balloon, an ultrasonic transmitter, an installation box, an air pump, a containment box, a rope, and a rotating shaft. The containment box and installation box are installed in the middle of crops in a field. The containment box is installed on the ground, and the rotating shaft is rotatably installed inside the installation box, which is installed below ground level. The air pump is installed inside the installation box and is connected to the balloon. When the ultrasonic transmitter needs to be used to repel pests from the crops, the air pump fills the balloon with a gas with a density lower than air. The balloon then carries the ultrasonic transmitter into the air, where it activates and directs downwards to repel pests from the crops. After the pests are repelled, the rope, rotating on the shaft, winds around it, pulling the ultrasonic transmitter into the containment box, thus retrieving both the balloon and the ultrasonic transmitter.

Description

Technical Field

[0001] This invention belongs to the field of pest control technology, and in particular relates to an ultrasonic pest control system that combines air and ground control. Background Technology

[0002] Ultrasonic pest control works by emitting high-frequency sound waves beyond the range of human hearing using an ultrasonic transmitter. This stimulates the auditory systems of pests such as rodents and insects, forcing them to flee the area where the ultrasonic pest control is applied. In physical control, the coverage radius of a single ground-based ultrasonic device is usually less than 15 meters, making it difficult to cope with the cross-regional spread of migratory pests (such as rice planthoppers).

[0003] Chinese invention patent publication number "CN112088869A" discloses "An ultrasonic insect repelling device for drones and its usage method." In this invention, the drone repelling insects drives them away from the trapping device during the insect-repelling process. The device, in conjunction with volatile inducing hormones and trapping fiber clusters, firmly fixes the insects inside, facilitating subsequent unified collection and disposal, thus achieving a relatively thorough repelling of pests. However, when using drones to drive ultrasonic waves to repel insects in crop planting areas, the drone needs to be operated to drive the ultrasonic waves. The drone's battery is limited, and the duration of a single use is fixed. When using ultrasonic insect repellent for extended periods, the drone's battery life will not meet the requirements.

[0004] Therefore, its shortcoming is that when the invention is used to drive away pests for a long time, the drone's battery life will not meet the requirements, so that the pests cannot be driven away in time. Summary of the Invention

[0005] In view of the shortcomings of the prior art described above, the purpose of this invention is to provide an air-ground combined ultrasonic pest control system to solve the problem of insufficient battery life of drones when drones are needed to drive away pests for a long time in the prior art.

The guide axis of the second guide tube is set vertically, and the axial extension line of the second guide tube coincides with the axial extension line of the first guide tube. The hose inside the mounting box passes through the second guide tube and the first guide tube in sequence before communicating with the balloon.

[0038] As described above, the air-ground combined ultrasonic insect repellent system of the present invention has at least the following beneficial effects:

[0039] 1. When it is necessary to repel pests from crops, this invention can use an air pump to fill a balloon with a gas that is less dense than air, so that the balloon can carry an ultrasonic transmitter into the air. The ultrasonic transmitter can then be activated to repel pests from crops downwards. The ultrasonic transmitter only needs the buoyancy of the balloon to fly into the air, thus ensuring that the ultrasonic transmitter can repel pests from crops at high altitudes for a long time.

[0040] 2. When the hose of the present invention is retracted from the installation box, the gas with a density lower than air inside the hose is first drawn back by an air pump and compressed into a gas storage bottle. Then, the rope is wound around the rotating shaft as the shaft rotates, thereby pulling the balloon down. When the balloon descends, the first rotary power source rotates forward, driving the first rotating column to wind the hose at the same speed as the balloon's descent, so that the hose is wound from between the roller and the second rotating column onto the first rotating column. When the balloon descends to the designated position and stops descending, the first telescopic power source retracts, causing the roller to squeeze the hose and press it onto the second rotating column. Then, the first rotary power source reverses, at which point the second rotary power source drives the second rotating column to reverse the first rotating column. The loosened hose rotates out of the first rotating column between the roller and the second rotating column. After rotation, the first telescopic power source extends, so that the roller no longer presses the hose. The air pump draws back the gas with a density lower than air inside the balloon and hose and compresses it into the gas storage bottle. This allows the roller, under the action of the first telescopic power source, to squeeze and press the hose onto the second rotating column when it is necessary to rotate the hose wrapped around the first rotating column out of the first rotating column. When it is necessary to extract the gas with a density lower than air from the balloon and hose, the roller, under the action of the first telescopic power source, leaves the state of pressing the hose, making it easier for the air pump to extract the gas with a density lower than air from the balloon and hose. The structure is ingeniously designed.

[0041] 3. This invention uses an ultrasonic transmitter in the air, propelled by a balloon, to repel insects from crops on the ground. Insect-repelling lamps then repel insects from crops below and around the guide plate. This combination of ultrasonic transmitters and insect-repelling lamps effectively repels insects from crops on the ground. Furthermore, the insect-repelling lamps can repel insects from areas not covered by the ultrasonic transmitter (crops below and around the guide plate). The insect-repelling lamps and ultrasonic transmitters work ingeniously together.

[0042] 4. The guide plate of the present invention can wrap around the mounting frame under the action of the second telescopic power source when the balloon is retracted into the container box. Thus, the guide plate guides the retracted mounting frame so that it can be accurately retracted into the container box. After retraction, the insect repellent lamp is located on the side wall of the guide plate away from the mounting frame, so that the insect repellent lamp can continue to be turned on to repel insects around the container box. The structure is ingeniously designed. Attached Figure Description

[0060] The following specific embodiments illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification.

[0061] Please see Figures 1 to 10 It should be understood that the structures, proportions, sizes, etc., depicted in the accompanying drawings are merely for illustrative purposes to aid those skilled in the art and to facilitate understanding. They are not intended to limit the scope of the invention and therefore have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the effectiveness and purpose of the invention, should still fall within the scope of the technical content disclosed herein. Furthermore, the terms "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity and not intended to limit the scope of the invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of the invention.

[0062] The following embodiments are for illustrative purposes only. These embodiments can be combined and are not limited to the content shown in any single embodiment below.

[0063] Please see Figure 1 , Figure 2 , Figure 7 and Figure 8 This invention provides an air-ground combined ultrasonic insect repellent system, the system comprising:

[0064] An ultrasonic insect repelling unit includes an ultrasonic transmitter 101, a mounting frame 102, and a balloon 103. The balloon 103 floats in the air, the mounting frame 102 is installed below the balloon 103, and the ultrasonic transmitter 101 is installed on the mounting frame 102. The ultrasonic transmitter 101 emits ultrasonic waves downwards to repel pests.

[0065] A gas control unit is installed below ground level. The gas control unit includes a hose 201 and an air pump 202. One end of the hose 201 is connected to a balloon 103, and the other end of the hose 201 is connected to the air pump 202. The hose 201 inflates or releases a gas with a density lower than air into the balloon 103 under the action of the air pump 202.

[0066] This does not restrict gases with a density lower than air; they can be hydrogen, helium, etc.

[0067] The deployment and retraction unit includes a receiving box 301, a rope 302, and a rotating shaft 303. The receiving box 301 is installed on the ground, and the rotating shaft 303 is rotatably installed inside the receiving box 301. One end of the rope 302 is fixedly connected to the mounting frame 102, and the other end of the rope 302 is fixedly connected to the rotating shaft 303. When the rotating shaft 303 is rotated, the balloon 103 will be extended and retracted to lower its height.

[0068] In this embodiment, the gas control unit and the deployment and retraction unit are installed in the middle of the crops in a field. When it is necessary to use the ultrasonic transmitter 101 to drive away pests from the crops, the air pump 202 fills the balloon 103 with a gas with a density lower than that of air. Then, the balloon 103 drives the ultrasonic transmitter 101 into the air. The ultrasonic transmitter 101 is activated and moves downward to drive away pests from the crops. After the pests are driven away, the rope 302 is wound around the rotating shaft 303 as the shaft rotates. During the winding process, the rope 302 pulls the mounting frame 102 into the housing box 301. The mounting frame 102 moves the balloon 103 together, thereby reducing the height of the balloon 103.

[0069] When it is necessary to repel pests from crops, the present invention can use an air pump 202 to fill a balloon 103 with a gas with a density lower than that of air, so that the balloon 103 can carry the ultrasonic transmitter 101 into the air. The ultrasonic transmitter 101 can then be activated to repel pests from crops downwards. The ultrasonic transmitter 101 only needs to be carried into the air by the balloon 103, thus ensuring that the ultrasonic transmitter 101 can repel pests from crops at high altitudes for a long time.

[0070] Please see Figure 1 and Figure 3 The gas control unit also includes a mounting box 203, a gas storage cylinder 204, a solenoid valve 205, and a rigid pipe 206;

[0071] The installation box 203 is installed below ground level. The air pump 202 and the air storage cylinder 204 are both fixedly installed inside the installation box 203. The air supply end of the air storage cylinder 204 is connected to the air inlet end of the air pump 202. The air supply end of the air storage cylinder 204 is connected to the air supply end of the air pump 202. The air pump 202's filling and discharging end is connected to one end of the solenoid valve 205. The other end of the solenoid valve 205 is connected to one end of the rigid pipe 206. The other end of the rigid pipe 206 is connected to the flexible hose 201. The flexible hose 201 passes through the installation box 203 and is connected to the balloon 103.

[0072] In this embodiment, when the balloon 103 is filled with gas, the solenoid valve 205 is opened, and the air pump 202 draws the compressed gas with a density lower than air from the gas storage bottle 204 into the gas supply end of the gas storage bottle 204, the gas filling and discharging end of the air pump 202, the solenoid valve 205, the rigid tube 206 and the flexible tube 201 in sequence before entering the balloon 103. When the balloon 103 is filled with gas with a density lower than air, the solenoid valve 205 is closed.

[0073] When gas is extracted from balloon 103, solenoid valve 205 is opened, and air pump 202 draws gas with a density lower than air from balloon 103 into hose 201, rigid tube 206, solenoid valve 205, the filling / discharging end of air pump 202 and the air inlet end of gas storage cylinder 204 in sequence, and then recompresses it into gas storage cylinder 204. When all the gas with a density lower than air in balloon 103 has been extracted, solenoid valve 205 is closed.

[0074] When inflating the balloon 103, the air pump 202 can draw gas with a density lower than air from the gas storage bottle 204 into the balloon 103. When extracting gas from the balloon 103, the air pump 202 can recompress the gas with a density lower than air from the balloon 103 back into the gas storage bottle 204, so that the gas with a density lower than air can be recycled.

[0075] Please see Figure 1 , Figure 3 and Figure 4 The gas control unit also includes a first rotating column 207, a rotating joint 208, a first channel 209, and a second channel 210;

[0076] The first rotating column 207 is rotatably installed in the mounting box 203. The rotation axis of the first rotating column 207 is parallel to the horizontal plane. The first rotating column 207 has a first channel 209 and a second channel 210. The axial extension line of the first channel 209 coincides with the rotation axis of the first rotating column 207.

[0077] One end of the first channel 209 passes through the end face of the first rotating column 207 near the air pump 202. The rigid tube 206 is connected to one end of the first channel 209 through a rotating joint 208. The other end of the first channel 209 is connected to one end of the second channel 210. The other end of the second channel 210 passes through the side wall of the first rotating column 207 and is connected to the flexible tube 201.

[0078] In this embodiment, when the balloon 103 is filled with gas, the solenoid valve 205 is opened, and the air pump 202 draws the compressed gas with a density lower than air from the gas storage bottle 204 into the gas supply end of the gas storage bottle 204, the gas filling and discharging end of the air pump 202, the solenoid valve 205, the rigid tube 206, the first channel 209, the second channel 210 and the flexible tube 201 in sequence before entering the balloon 103. When the balloon 103 is filled with gas with a density lower than air, the solenoid valve 205 is closed.

[0079] When gas is extracted from balloon 103, solenoid valve 205 is opened, and air pump 202 sequentially draws the gas with a density lower than air from balloon 103 into hose 201, second channel 210, first channel 209, rigid tube 206, solenoid valve 205, the filling / discharging end of air pump 202 and the air inlet end of gas storage cylinder 204, and then recompresses it into gas storage cylinder 204. When the gas with a density lower than air in balloon 103 is completely extracted, solenoid valve 205 is closed.

[0080] When the first rotating column 207 rotates, the rotating joint 208 and the first rotating column 207 rotate together around the rigid tube 206, while the rigid tube 206 remains stationary. This allows the rope 302 to wrap around the rotating shaft 303 during the subsequent retrieval of the balloon 103, thereby lowering the height of the balloon 103. The rotation of the first rotating column 207 also wraps around the flexible tube 201 to temporarily collect the flexible tube 201 into the installation box 203. At this time, the rigid tube 206 and the flexible tube 201 remain connected. The structure is ingeniously designed.

[0081] Please see Figure 1 and Figure 3 The gas control unit also includes a first rotary power source 211, a first gear 212, and a second gear 213;

[0082] The first rotary power source 211 is not limited here. Its function is to provide rotary power, and it can be an AC motor, a stepper motor, etc.

[0083] The first gear 212 is fixedly connected to the first rotating column 207, and the rotation axis of the first gear 212 coincides with the rotation axis of the first rotating column 207;

[0084] The first rotary power source 211 is installed in the mounting box 203. The rotating end of the first rotary power source 211 is fixedly connected to the second gear 213, and the second gear 213 is engaged with the first gear 212.

[0085] In this embodiment, when the ultrasonic transmitter 101 finishes repelling the insects and retracts the balloon 103, the rope 302 is wound around the rotating shaft 303 as the shaft rotates, thereby lowering the height of the balloon 103. The first rotating power source 211 drives the second gear 213 to rotate at the same speed as the balloon 103 descends. The second gear 213 drives the first gear 212 to rotate. The first gear 212 drives the first rotating column 207 to rotate together. The first rotating column 207 rotates and winds the hose 201, thereby temporarily collecting the hose 201 into the installation box 203.

[0086] The first rotating power source 211 of the present invention can wind the hose 201 at the same speed as the balloon 103 descends, thereby vertically retracting the hose 201 above the ground after the balloon 103 descends into the installation box 203, thus avoiding the problem of the hose 201 being caught by crops above the ground.

[0087] Please see Figure 1 , Figure 2 , Figure 3 and Figure 5 The gas control unit also includes a second rotating column 214, a second rotating power source 215, a mounting block 216, a first telescopic power source 217, a sliding block 218, a first sliding groove 219, a partition 220, and a roller 221.

[0088] The second rotary power source 215 is not limited here; its function is to provide rotary power, and it can be an AC motor, a stepper motor, etc.

[0089] The first telescopic power source 217 is not limited here. Its function is to provide telescopic power, and it can be a cylinder, hydraulic cylinder, etc.

[0090] The second rotating column 214 is rotatably installed inside the mounting box 203, and the rotation axis of the second rotating column 214 is parallel to the rotation axis of the first rotating column 207;

[0091] The second rotary power source 215 is installed in the mounting box 203. The rotating end of the second rotary power source 215 is fixedly connected to one end of the second rotary column 214. The rotation axis of the second rotary power source 215 coincides with the rotation axis of the second rotary column 214.

[0092] The mounting block 216 is fixedly installed inside the mounting box 203. The mounting box 203 has a first sliding groove 219. The sliding guide direction of the first sliding groove 219 is parallel to the horizontal plane and perpendicular to the rotation axis of the second rotating column 214. The sliding block 218 is slidably disposed inside the first sliding groove 219. The roller 221 is rotatably mounted on the sliding block 218. The rotation axis of the roller 221 is parallel to the rotation axis of the second rotating column 214. The fixed end of the first telescopic power source 217 is fixedly connected to the mounting block 216, and the extended end of the first telescopic power source 217 is fixedly connected to the sliding block 218. The telescopic direction of the first telescopic power source 217 is parallel to the sliding guide direction of the first sliding groove 219. Under the action of the first telescopic power source 217, the roller 221 compresses or releases the hose 201 between the roller 221 and the second rotating column 214.

[0093] The partition 220 is located inside the mounting box 203. The upper end face of the partition 220 is in contact with the side wall of the second rotating column 214, and the lower end face of the partition 220 is fixedly connected to the lower end face of the mounting box 203. The second rotating column 214 is located between the roller 221 and the first rotating column 207.

[0094] In this embodiment, when the balloon 103 is filled with gas, the solenoid valve 205 opens, and the air pump 202 draws the compressed gas with a density lower than air from the gas storage cylinder 204 sequentially into the gas supply end of the gas storage cylinder 204, the gas filling and discharging end of the air pump 202, the solenoid valve 205, the rigid pipe 206, the first channel 209, the second channel 210, and the flexible hose 201 before entering the balloon 103. When the balloon 103 is filled with gas with a density lower than air, the solenoid valve 205 closes, and the balloon 103, along with the flexible hose 201 inside the mounting box 203, rises together. Then, the ultrasonic transmitter 101 turns on to... After pest control is performed on the crops, the solenoid valve 205 is opened, and the air pump 202 draws gas with a density lower than air from the hose 201 into the second flexible channel 210, the first channel 209, the rigid tube 206, the solenoid valve 205, the filling / discharging end of the air pump 202, and the air inlet end of the gas cylinder 204, and then recompresses it into the gas cylinder 204. The solenoid valve 205 is then closed, and the rope 302 is wound around the rotating shaft 303 as the shaft rotates, thereby lowering the height of the balloon 103. As the balloon 103 lowers, the first rotational power source 211... The forward rotation drives the first rotating column 207 to wind the hose 201 at the same speed as the balloon 103 descends, causing the hose 201 to rotate from between the roller 221 and the second rotating column 214 onto the first rotating column 207. When the balloon 103 descends to the designated position and stops descending, the first telescopic power source 217 retracts, causing the roller 221 to squeeze the hose 201 and press it onto the second rotating column 214. Then, the first rotating power source 211 reverses direction, at which point the second rotating power source 215 drives the second rotating column to pull the hose 201, which was released from the first rotating column 207, from the roller 221 and the second rotating column 214. The first rotating column 207 rotates out between the rotating columns 214. After the rotation is complete, the first telescopic power source 217 extends, so that the roller 221 no longer presses the hose 201. The air pump 202 draws the gas with a density lower than air from the balloon 103 and the hose 201 into the hose 201, the second channel 210, the first channel 209, the rigid tube 206, the solenoid valve 205, the inflation and deflation end of the air pump 202 and the air inlet end of the gas storage bottle 204, and then recompresses it into the gas storage bottle 204. When the gas with a density lower than air in the balloon 103 is completely drawn out, the solenoid valve 205 closes, waiting for the next insect repellent operation.

[0095] The roller 221 of the present invention, under the action of the first telescopic power source 217, can squeeze and press the hose 201 wound on the first rotating column 207 onto the second rotating column 214 when it is necessary to rotate the hose 201 wound on the first rotating column 207 out of the first rotating column 207. When the balloon 103 and the hose 201 need to extract gas with a density lower than air, the roller 221 leaves the state of pressing the hose 201 under the action of the first telescopic power source 217, so that the air pump 202 can extract the gas with a density lower than air from the balloon 103 and the hose 201. The structure is ingeniously designed.

[0096] Please see Figure 6 and Figure 7 The retractable unit also includes a second telescopic power source 401, a telescopic frame 402, a second slide 403, an elastic hinge 404, a guide plate 405, and an insect repellent lamp 406.

[0097] The second telescopic power source 401 is not limited here; its function is to provide telescopic power, and it can be a cylinder, hydraulic cylinder, etc.

[0098] The fixed end of the second telescopic power source 401 is fixedly connected to the receiving box 301. The telescopic direction of the second telescopic power source 401 is vertically set. The extended end of the second telescopic power source 401 is fixedly connected to the telescopic frame 402. The receiving box 301 is vertically provided with a second sliding groove 403. The telescopic frame 402 moves along the sliding guide direction of the second sliding groove 403 under the action of the second telescopic power source 401.

[0099] Each inner wall of the telescopic frame 402 is fixedly connected to one end of an elastic hinge 404, and the other end of each elastic hinge 404 is fixedly connected to a guide plate 405. When the telescopic frame 402 extends out of the receiving box 301 under the action of the second telescopic power source 401, the guide plate 405 can rotate from a vertical state to a horizontal state under the action of the elastic hinge 404.

[0100] Each of the guide plates 405 is fixedly connected to an insect repellent lamp 406. When the guide plate 405 is rotated to a horizontal position, the insect repellent lamp 406 is located below the guide plate 405.

[0101] In this embodiment, when it is necessary to repel pests from crops using the ultrasonic transmitter 101, the second telescopic power source 401 is first extended. The second telescopic power source 401 pushes the telescopic frame 402 upward. When the telescopic frame 402 rises to the point where the guide plate 405 begins to open, the air pump 202 fills the balloon 103 with a gas with a density lower than air. After it is full, the rotating shaft 303 rotates to unwind the rope 302 wrapped around the rotating shaft 303. The rope 302 then drives the balloon 103 upward. After rising, the second telescopic power source 401 continues to... The balloon 103 continues to extend. After extending, the guide plate 405 rotates from a vertical state to a horizontal state under the action of the elastic hinge 404. Then the balloon 103 continues to rise. After rising to a designated height, the pivot 303 stops rotating, thus stopping the balloon 103 at the designated height. Then the insect repellent lamp 406 and the ultrasonic transmitter 101 are turned on. The insect repellent lamp 406 on the ground repels insects to the crops below and around the guide plate 405, and the ultrasonic transmitter 101 repels insects to the crops on the ground.

[0102] This invention uses an ultrasonic transmitter 101 in the air to repel insects from crops on the ground, and an insect-repelling lamp 406 to repel insects from crops below and around the guide plate 405 on the ground. This method combines air and ground methods to repel insects from crops on the land. Furthermore, areas not covered by the ultrasonic waves emitted by the ultrasonic transmitter 101 (crops below and around the guide plate 405) can be repelled by the insect-repelling lamp 406, making the insect-repelling range of this invention more comprehensive.

[0103] Please see Figure 1 , Figure 7 , Figure 8 and Figure 9 The retracting unit also includes a first bevel gear set 304, a third rotary power source 305, a pressure sensor 306, a third guide tube 307, and a fourth guide tube 308;

[0104] The third rotary power source 305 is not limited here; its function is to provide rotary power, and it can be an AC motor, a stepper motor, etc.

[0105] The rotating shaft 303 is rotatably installed inside the telescopic frame 402, and the rotation axis of the rotating shaft 303 is set horizontally.

[0106] The fixed end of the third rotary power source 305 is fixedly installed on the telescopic frame 402, and the rotating end of the third rotary power source 305 is fixedly connected to one end of the first bevel gear set 304, and the other end of the first bevel gear set 304 is fixedly connected to the rotating shaft 303.

[0107] The third guide tube 307 and the fourth guide tube 308 are both fixed to the telescopic frame 402. The third guide tube 307 is located below the fourth guide tube 308. The guide axes of the fourth guide tube 308 and the third guide tube 307 are vertically arranged, and the guide axis of the fourth guide tube 308 is consistent with the guide axis of the third guide tube 307. The fourth guide tube 308 is a rectangular column. A pressure sensor 306 is installed on each of the four side walls of the fourth guide tube 308. Through holes are opened on the four side walls of the fourth guide tube 308. After the pressure sensor 306 is inserted into the through hole, it surrounds the inner wall of the fourth guide tube 308.

[0108] One end of the rope 302 is fixedly connected to one end of the mounting frame 102 along its length, and the other end of the rope 302 passes through the fourth guide tube 308 and the third guide tube 307 and is fixedly connected to the rotating shaft 303.

[0109] In this embodiment, two take-up and release units are provided, which are located on both sides of the mounting frame 102 along its length, and the junctions of the two ropes 302 with the mounting frame 102 are symmetrical along the center of the ultrasonic transmitter 101.

[0110] In this embodiment, when it is necessary to repel pests from crops using the ultrasonic transmitter 101, the second telescopic power source 401 is first extended, pushing the telescopic frame 402 upward. When the telescopic frame 402 rises to the point where the guide plate 405 begins to open, the air pump 202 fills the balloon 103 with a gas of lower density than air. After filling, the two third rotary power sources 305 drive their corresponding rotating shafts 303 to rotate at the same speed, causing the rotating shafts 303 to unwind the ropes 302 wrapped around them. The ropes 302 then carry the balloon 103 upward. After rising, the second telescopic power source 401 continues to extend. After extending, the guide plate 405, under the action of the elastic hinge 404, rotates from a vertical state to a horizontal state towards the outer wall of the telescopic frame 402. Then, the balloon 103 continues to rise. After rising to a designated height, the two third rotary power sources 305 stop rotating, causing the rotating shafts 303 to stop rotating, thus stopping the balloon 103 at the designated position. At a set height, the insect-repelling lamp 406 and ultrasonic transmitter 101 are turned on. The insect-repelling lamp 406 on the ground repels insects to the crops below and around the guide plate 405, and the ultrasonic transmitter 101 repels insects to the crops on the ground. When the pressure sensor 306 detects that the pressure of the fourth guide tube 308 on the rope 302 is greater than the set threshold, the two third rotational power sources 305 drive the corresponding rotating shafts 303 to rotate at the same speed, so that the rotating shafts 303 rewrap the ropes 302 around the rotating shafts 303. During this process, the balloon 103 and the mounting frame 102 will slowly descend. During the descent, the second telescopic power source 401 retracts and pushes the telescopic frame 402 down. After extending, the guide plate 405 rotates from a horizontal state back to a vertical state under the action of the elastic hinge 404. Finally, the guide plate 405 wraps around the descending mounting frame 102, thereby storing the mounting frame 102 into the housing box 301.

[0111] The guide plate 405 of the present invention can wrap around the mounting frame 102 under the action of the second telescopic power source 401 when the balloon 103 is retracted. Thus, the guide plate 405 guides the retracted mounting frame 102 so that it can be accurately retracted into the receiving box 301. After retraction, the insect repellent lamp is located on the side wall of the guide plate 405 away from the mounting frame 102, so that the insect repellent lamp can continue to be turned on to repel insects around the receiving box 301. The structure is ingeniously designed.

[0112] Please see Figure 1 and Figure 10 The ultrasonic insect repellent unit also includes a fourth rotating column 501, a second bevel gear set 502, a counterweight 504, and a fourth rotating power source 503.

[0113] The fourth rotary power source 503 is not limited here; its function is to provide rotary power, and it can be an AC motor, a stepper motor, etc.

[0114] The ultrasonic transmitter 101 is fixedly mounted on the fourth rotating column 501, which is rotatably mounted on the mounting frame 102. The rotation axis of the fourth rotating column 501 is horizontally set and parallel to the length direction of the mounting frame 102.

[0115] The fixed end of the fourth rotary power source 503 is fixedly installed on the mounting bracket 102, and the rotating end of the fourth rotary power source 503 is fixedly connected to one end of the second bevel gear set 502, and the other end of the second bevel gear set 502 is fixedly connected to the fourth rotating column 501.

[0116] The counterweight 504 is installed on the mounting frame 102. The counterweight 504 is used to balance the weight of the fourth rotating column 501 and the second bevel gear set 502, so that the mounting frame 102 rises smoothly during the process of the balloon 103 rising.

[0117] In this embodiment, when it is necessary to adjust the insect-repelling angle of the ultrasonic transmitter 101 along the width direction of the mounting frame 102, the fourth rotating power source 503 rotates to drive the fourth rotating column 501 to rotate by a corresponding angle, so that the ultrasonic transmitter 101 rotates by a certain angle along the width direction of the mounting frame 102.

[0118] When it is necessary to adjust the insect-repelling angle of the ultrasonic transmitter 101 along the length of the mounting frame 102, the third rotational power source 305 on the corresponding side of the mounting frame 102 along the length of the mounting frame 102 drives the corresponding rotating shaft 303 to rotate. This rotating shaft 303 drives the corresponding rope 302 to wrap around a certain length of rope 302 on the rotating shaft 303, while the third rotational power source 305 on the other side does not rotate, thereby pulling the mounting frame 102 to tilt to one side along the length of the mounting frame 102, so that the ultrasonic transmitter 101 rotates at a certain angle along the length of the mounting frame 102.

[0119] After the ultrasonic transmitter 101 of the present invention is lifted into the air by the balloon 103, when it is necessary to adjust the irradiation angle of the ultrasonic transmitter 101, the fourth rotating column 501 can be rotated by the fourth rotating power source 503 to rotate by a corresponding angle, so that the ultrasonic transmitter 101 rotates by a certain angle in the width direction of the mounting frame 102. Alternatively, the third rotating power source 305 on the corresponding side of the length direction of the mounting frame 102 can be used to rotate the corresponding rotating shaft 303. By pulling the rope 302 on one side, the ultrasonic transmitter 101 can be rotated by a certain angle in the length direction of the mounting frame 102. Thus, ultrasonic pest control of crops can be achieved from multiple angles, and the range of ultrasonic pest control is wider.

[0120] Please see Figure 6 The system also includes a third telescopic power source 601, a mounting column 602, and a sliding column 603;

[0121] The third telescopic power source 601 is not limited here; its function is to provide telescopic power, and it can be a cylinder, hydraulic cylinder, etc.

[0122] The mounting column 602 is fixedly installed on the ground. The fixed end of the third telescopic power source 601 is fixedly installed inside the mounting column 602. The telescopic direction of the third telescopic power source 601 is vertically set. The sliding column 603 is fixedly connected to the lower end face of the receiving box 301. The extended end of the third telescopic power source 601 is fixedly connected to the sliding column 603. The sliding column 603 drives the receiving box 301 to move up and down under the action of the third telescopic power source 601.

[0123] In this embodiment, when the crops around the container 301 grow higher than the container 301, before insect repellent, the third telescopic power source 601 extends to raise the container 301 above the crops, and then the subsequent insect repellent operation is carried out.

[0124] When repelling insects, the container 301 of the present invention can rise a certain distance under the action of the third telescopic power source 601, so that the container 301 is higher than the crops, so that when the subsequent guide plate 405 is rotated from the vertical state to the outer wall of the telescopic frame 402 to the horizontal state under the action of the elastic hinge 404, it will not crush the crops.

[0125] Please see Figure 1 The system also includes a first guide tube 701 and a second guide tube 702;

[0126] The first guide tube 701 is fixed to the receiving box 301 and is located at the junction between two outer side walls of the receiving box 301. The guide axis of the first guide tube 701 is vertically set.

[0127] The second guide tube 702 is fixedly connected to the mounting box 203, and the second guide tube 702 passes through the upper end face of the mounting box 203 and the ground in sequence before extending above the ground. The guide axis of the second guide tube 702 is set vertically, and the axial extension line of the second guide tube 702 coincides with the axial extension line of the first guide tube 701. The hose 201 in the mounting box 203 passes through the second guide tube 702 and the first guide tube 701 in sequence and then communicates with the balloon 103.

[0128] The diameter of the inner wall of the first guide tube 701 is the same as the diameter of the inner wall of the second guide tube 702, and the diameter of the inner wall of the first guide tube 701 is larger than the diameter of the outer wall of the hose 201.

[0129] In this embodiment, when the balloon 103 needs to be released for insect repellent, the balloon 103 is filled with a gas with a density lower than air through the hose 201. The hose 201 extending out of the mounting box 203 passes through the second guide tube 702 and the first guide tube 701 in sequence and then connects with the balloon 103. When the balloon 103 needs to be retracted after the insect repellent is completed, the hose 201 located above the first guide tube 701 passes through the first guide tube 701 and the second guide tube 702 in sequence under the winding of the first rotating column and then enters the mounting box 203.

[0130] The first guide tube 701 of the present invention is located at the junction between two outer walls of the receiving box 301, thereby guiding the hose 201 above the first guide tube 701. This ensures that when the subsequent guide plate 405 rotates from a horizontal state to a vertical state under the action of the elastic hinge 404, it will not clamp the hose 201. In other words, the hose 201 avoids the rotation path of the guide plate 405, thereby protecting the hose 201.

[0131] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the invention. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of the present invention.
