Description

Technical Field

[0001] The present invention relates to the field of ecological pest control, and particularly to an unmanned aerial vehicle (UAV) ecological pest control system and method. Background Art

[0002] At present, for agricultural pest control in various countries around the world, it is generally dependent on the old-fashioned spraying of pesticides or the relatively new fixed high-voltage field technology for trapping. Spraying pesticides causes relatively large pollution to farmland soil and air. Although the fixed high-voltage field technology can effectively trap pests, the controlled area is small. When large-scale pests occur in farmland, it is necessary to expand the area of the high-voltage field. However, due to limited space, sometimes it is impossible to control the entire area of the pest disaster.

[0003] Therefore, a high-voltage electric field pest control UAV with the application number 202122468033.7 realizes the adjustment of the position of the high-voltage electric field pest control unit in the high altitude through the UAV, greatly increases the overall mobility of the device, solves the problem of space limitation for the large-area installation of the high-voltage electric field trap, and realizes the function of trapping pests in a large range of crops with a small-area high-voltage electric field trap.

[0004] However, when the UAV is flying with a high-voltage electric field trap, it cannot effectively trap and concentrate pests at the high-voltage electric field. It only relies on the flight of the UAV to make the high-voltage electric field contact the pests. The treatment process overly depends on the UAV flight technology and cannot effectively capture pests, thereby reducing the pest control efficiency.

[0005] Secondly, the UAV carrying a high-voltage electric field trap consumes a large amount of power. When the UAV runs out of power, the device is prone to crashing, which not only consumes more costs but also easily causes accidents. Summary of the Invention

[0006] An object of the present invention is to provide an unmanned aerial vehicle ecological pest control system and method. By adjusting the rotation of a plurality of rotating blades, the plurality of rotating blades are tilted outwards, or two adjacent rotating blades are in contact with each other. When the UAV is used for pest control, the rotating blades generate a spiral wind to further capture pests. At the same time, when the power of the UAV is lower than the threshold, the rotating blades achieve the effect of a parachute to avoid damage to the UAV.

[0007] The above object is achieved by the following technical solutions:

[0008] An unmanned aerial vehicle ecological pest control system and method, including a UAV component, and a pest control unit is arranged below the UAV component; a first rotating rod is arranged above the UAV component, a connecting plate and a first ring are sequentially arranged on the first rotating rod from top to bottom, a plurality of rotating blades are arranged between the connecting plate and the first ring, the upper end of the rotating blade is connected to the connecting plate, and the upper end of the rotating blade can rotate on the connecting plate. The lower end of the rotating blade is provided with a rotating shaft, and the lower end of the rotating shaft passes through the first ring.

[0009] An adjusting member is provided on the first ring. The adjusting member is used to drive the circumferential rotation of the rotating shaft, so that a plurality of rotating blades incline outwards, or make two adjacent rotating blades contact each other.

[0010] During use, when the drone component drives the system to fly, the adjusting member drives the circumferential rotation of the rotating shaft, so that a plurality of rotating blades incline outwards. At this time, an air outlet is formed between two adjacent rotating blades, and the first rotating rod drives the rotating blade to rotate around the straight line where the first rotating rod is located through the first ring.

[0011] A plurality of rotating blades will generate spiral air flow during rotation. The spiral wind generates an adsorption effect under the action of inertia, driving the surrounding air and sundries to rotate together. The rotating air plays a stirring role, driving the surrounding flying insects to rotate. When approaching the flying insects, the spiral air flow drives the flying insects closer to the system, and makes more flying insects enter the insecticidal unit through the spiral air flow. The insecticidal unit conducts killing treatment on the flying insects.

[0012] The existing drone insecticidal system drives the insecticidal unit to approach the flying insects for killing through the flight of the drone component. This process relies too much on the flight skills of the operator, and when the existing drone insecticidal system kills flying insects, the flying insects are prone to escape, affecting the killing effect.

[0013] Therefore, the system generates spiral air flow through the rotating blades. The air between the rotating blades forms rotating wind under the action of centrifugal force and rotational inertia force. The spiral wind generates an adsorption effect under the action of inertia, driving the surrounding flying insects to rotate. When approaching the flying insects, the spiral air flow drives the flying insects closer to the system, and makes more flying insects enter the insecticidal unit through the spiral air flow. The insecticidal unit conducts killing treatment on the flying insects. Therefore, during the flight of the system, it is not necessary to be too close to the flying insects, and more flying insects can enter the insecticidal unit through the spiral wind, further improving the insecticidal efficiency.

[0014] On the other hand, when the power value of the power module of the drone component of the system is less than or equal to the threshold value, the adjusting member drives the circumferential rotation of the rotating shaft, so that two adjacent rotating blades contact each other. A plurality of rotating blades form a closed surface, that is, there is no air outlet between two adjacent rotating blades. Preferably, the rotating blade includes a frame plate and a second parachute canopy provided on the frame plate. Therefore, when a plurality of rotating blades form a closed surface, the air resistance is significantly increased, reducing the acceleration of the system's fall and avoiding the phenomenon of damage to the drone component caused by high-speed falling.

[0015] Compared with the existing UAV insecticidal system, during the insecticidal process, this system converges flying insects to the lower insecticidal unit through the air outlets between the rotating blades and the spiral wind generated by rotation, improving the insecticidal efficiency. On the other hand, when the power value of the power module of the UAV component is less than or equal to the threshold, this system forms a closed surface by the rotating blades, increasing the air resistance to avoid falling at high speed, further protecting the UAV component and reducing damage.

[0016] Based on the above system, the adjustment of the rotation of the rotating shaft by the adjusting member can be achieved through various structures. To further improve the efficiency and simplify the structure, the inventor of the present invention preferably adopts a structure of the adjusting member. Specifically, the adjusting member includes a first gear provided at the lower end of the rotating shaft. A second ring is provided on the first ring, and the second ring can rotate circumferentially on the first ring. A second gear is provided on the side surface of the second ring, and the second gear meshes with a plurality of first gears. The circumferential rotation of the second ring drives the circumferential rotation of the plurality of first gears and the rotating shaft.

[0017] Among them, a plurality of first gears are externally tangent to the second gear. When the second gear rotates, the second gear drives the circumferential rotation of the plurality of first gears. When the first gears rotate circumferentially, they drive the rotating shaft thereon to rotate circumferentially. When the rotating shaft rotates, it drives the rotating blades to rotate, realizing the adjustment of the angle of the rotating blades, so that two adjacent rotating blades are in contact with each other and form a closed surface; or, an air outlet is formed between two adjacent rotating blades.

[0018] On the other hand, the circumferential rotation of the second ring of this system can be achieved through various structures. The inventor further provides an acting member on the first rotating rod. The acting member includes a sixth gear and a fifth gear. A coaxial rod is connected between the sixth gear and the fifth gear. A fourth gear is provided on the lower end surface of the second ring, and the fifth gear meshes with the fourth gear;

[0019] When the fifth gear rotates, it drives the sixth gear to rotate through the coaxial rod. When the sixth gear rotates, it acts on the fourth gear of the second ring, and the second ring rotates circumferentially.

[0020] Further, a placement groove is provided on the side surface of the first rotating rod. An acting rod is provided in the placement groove. A third gear is provided on the acting rod, and the fifth gear meshes with the third gear. The fifth gear drives the acting rod to move in the placement groove along the direction of the axis of the first rotating rod by rotation;

[0021] When the power value of the power module of the UAV component is greater than the threshold, the fifth gear rotates to move the acting rod upward, and an air outlet is formed between two adjacent rotating blades; at this time, the function of the rotating blades is to generate spiral wind to adsorb flying insects.

[0022] When the power value of the power module of the drone component is less than or equal to the threshold, the actuating rod moves downward under the action of gravity, causing the fifth gear to rotate in the reverse direction, and two adjacent rotating blades to come into contact with each other. At this time, the rotating blades act similarly to a parachute, buffering the descending speed and preventing high-speed descent to avoid damage to the drone component.

[0023] Preferably, the connecting plate is in a circular ring structure, and a first parachute canopy is provided on the connecting plate. The rotating blade includes a frame plate and a second parachute canopy provided on the frame plate.

[0024] Preferably, an insect attracting lamp is provided at the upper end of the first rotating rod. The insect attracting lamp utilizes the phototaxis of flying insects to attract pests through a specific light source and achieve physical killing.

[0025] The insect killing unit includes a collection funnel, and a high-voltage electric shock grid module is provided on the collection funnel. The high-voltage electric shock grid module is realized through a high-voltage resonance circuit.

[0026] The small end of the collection funnel is connected to a negative pressure collection bag, which is a device for collecting solid waste through the negative pressure principle.

[0027] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0028] For an unmanned aerial vehicle ecological insect killing system and method of the present invention, by adjusting the rotation of a plurality of rotating blades, the plurality of rotating blades are tilted outwards, and an air outlet is formed between two adjacent rotating blades. When driving the rotating blades to rotate around the straight line where the first rotating rod is located, a spiral wind is formed by the rotating blades. The spiral wind generates an adsorption effect under the action of inertia, driving the surrounding flying insects to rotate. When approaching the flying insects, the spiral air flow drives the flying insects closer to the system, and more flying insects enter the insect killing unit through the spiral air flow. The insect killing unit conducts killing treatment on the flying insects.

[0029] When the power value of the power module of the drone component is less than or equal to the threshold, without the power action, the fifth gear cannot support the weight of the actuating rod. Therefore, under the action of gravity, the actuating rod moves downward, causing the fifth gear to rotate in the reverse direction, and the rotating blades rotate in the reverse direction to the original position, that is, two adjacent rotating blades come into contact with each other, achieving the buffer protection effect of a parachute.

Detailed implementation manners

[0040] To make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below in combination with examples and drawings. The illustrative embodiments and descriptions of the present invention are only used to explain the present invention and shall not be construed as a limitation to the present invention.

[0041] In the description of the present invention, it should be understood that the orientation or positional relationships indicated by the terms "front", "rear", "left", "right", "upper", "lower", "vertical", "horizontal", "high", "low", "inner", "outer", etc. are based on the orientation or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, 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 protection scope of the present invention.

[0042] Example 1

[0043] As Figure 1As shown, it includes a drone component 15, and a pest control unit is arranged below the drone component 15; a first rotating rod 1 is arranged above the drone component 15. A connecting plate 3 and a first ring 2 are sequentially arranged on the first rotating rod 1 from top to bottom, and a plurality of rotating blades 4 are arranged between the connecting plate 3 and the first ring 2.

[0044] As Figure 2 shown, a rotating shaft 5 is arranged at the lower end of the rotating blade 4. The lower end of the rotating shaft 5 passes through the first ring 2, and the lower end of the rotating shaft 5 is connected to a first gear 7. The upper end of the rotating blade 4 is connected to the connecting plate 3 through a connecting shaft 41. When the first gear 7 rotates, the first gear 7 drives the rotating shaft 5 and the rotating blade 4 to rotate together. During the rotation of the rotating blade 4, the rotating blade 4 rotates around the connecting shaft 41 on the connecting plate 3.

[0045] When the rotating blade 4 rotates, there are two states in this system. The first state is that two adjacent rotating blades 4 are in contact with each other. As Figure 3 shown, a plurality of rotating blades 4 form a closed surface. In this state, the rotating blades play the role of a parachute.

[0046] The second state is that a plurality of rotating blades 4 are inclined outward. As Figure 4 shown, an air outlet is formed between two adjacent rotating blades 4. A fixing rod 9 is connected between the first rotating rod 1 and the first ring 2. Therefore, when the first rotating rod 1 rotates circumferentially, the rotating blade 4 is driven to rotate around the straight line where the first rotating rod 1 is located through the fixing rod 9 and the first ring 2; in this state, the rotating blades play the role of generating spiral wind.

[0047] In some embodiments, the pest control unit includes an air extraction component. When a plurality of rotating blades 4 generate spiral wind, the spiral air flow is drawn downward into the pest control unit through the air extraction component, so that more flying insects enter the pest control unit, thereby improving the pest control efficiency of this system.

[0048] In some embodiments, the rotating blade is arc-shaped. When two adjacent rotating blades 4 are in contact with each other, the rotating shaft 5 is in the original state. After the rotating shaft rotates 15 - 80 degrees in the original state, a plurality of rotating blades 4 are inclined outward, which is the second state.

[0049] During the rotation of the first rotating rod, the leaf surface of the rotating blade is arc-shaped and forms a certain angle with the first rotating rod. When the rotating blade rotates, negative pressure is generated at the inlet end, sucking air into the space between the rotating blade and the first rotating rod. The air is driven to generate centrifugal force between the rotating blade and the first rotating rod, and is thrown out under the action of the shear force and thrust of the rotating blade. The spiral wind generates an adsorption effect under the action of inertia, driving the surrounding flying insects to rotate. When approaching the flying insects, the spiral air flow drives the flying insects closer to this system, and more flying insects enter the pest control unit through the spiral air flow. The pest control unit conducts killing treatment on the flying insects.

[0050] Among them, the shape of the rotating piece 4 can be various, as long as the above two states can be achieved. The specific shape structure of the rotating piece is not limited in this embodiment. Preferably, the rotating piece is arc-shaped. When several rotating pieces 4 form a closed surface, the closed surface is a partial surface of an ellipsoid.

[0051] Embodiment 2

[0052] Based on the above embodiment, a method for ecological pest control by an unmanned aerial vehicle includes the following steps:

[0053] Step 1, when the power value of the power module of the unmanned aerial vehicle component 15 is greater than the threshold, the rotating shaft 5 rotates circumferentially, so that several rotating pieces 4 incline outwards, and an air outlet is formed between two adjacent rotating pieces 4;

[0054] Step 2, the first rotating rod 1 drives the rotating piece 4 to rotate with the straight line where the first rotating rod 1 is located as the axis; the rotating piece 4 rotates to form a spiral air flow to make flying insects approach the system and enter the pest control unit more;

[0055] Step 3, the air extraction component extracts the air flow above into the pest control unit, and the pest control unit kills pests through a high-voltage electric field;

[0056] Step 4, when the power value of the power module of the unmanned aerial vehicle component 15 is less than or equal to the threshold, the rotating shaft 5 rotates in the reverse direction, so that two adjacent rotating pieces 4 contact each other and several rotating pieces 4 form a closed surface.

[0057] Preferably, the connecting plate 3 is a circular ring structure, and a first parachute is arranged on the connecting plate 3. The rotating piece 4 includes a frame plate and a second parachute arranged on the frame plate. Both the first parachute and the second parachute are made of aramid fiber materials for high-performance parachutes, with high tensile strength and high temperature resistance. The frame plate is at the edge of the rotating piece, and the second parachute is located in the hollow area at the center of the frame plate. The frame plate can not only form a good support for the second parachute, but also achieve a better effect of generating spiral wind or parachute buffering.

[0058] Embodiment 3

[0059] Based on the above embodiment, a second ring 8 is arranged on the first ring 2, and a second gear is arranged on the side surface of the second ring 8. As Figure 5 shown, the second gear meshes with several first gears 7. The second ring 8 can rotate circumferentially on the first ring 2. Specifically, the second ring 8 and the first ring 2 are connected by a circular groove and a convex block, and the second ring 8 rotates circumferentially on the first ring 2 through the circular groove and the convex block.

[0060] When the second ring 8 rotates circumferentially, the second gear on the second ring 8 acts on the first gear 7, driving the first gear 7 to rotate circumferentially. When the first gear 7 rotates circumferentially, it drives the rotating shaft to rotate circumferentially, and the rotating shaft drives the rotating blade 4 to rotate.

[0061] In some embodiments, the circumferential rotation of the second ring 8 can be achieved through various structures. For example, the second ring is connected to a motor, and the motor drives the second ring to rotate.

[0062] In some embodiments, a acting member is provided on the first rotating rod 1. The acting member includes a sixth gear 10 and a fifth gear 12. A coaxial rod 11 is connected between the sixth gear 10 and the fifth gear 12. A fourth gear is provided on the lower end surface of the second ring 8. The sixth gear 10 meshes with the fourth gear. The motor is connected to the fifth gear 12, and the motor drives the fifth gear 12 to rotate circumferentially. When the fifth gear 12 rotates, it drives the sixth gear 10 to rotate circumferentially through the coaxial rod 11. When the sixth gear 10 rotates, it acts on the fourth gear of the second ring 8, causing the second ring to rotate circumferentially, thereby achieving the effect of driving the first gear 7 to rotate circumferentially.

[0063] Embodiment 4

[0064] Based on Embodiment 3, as Figure 6 shown, a placement groove is provided on the side surface of the first rotating rod 1. A acting rod 13 is provided in the placement groove. The acting rod 13 can move in the placement groove along the direction of the axis of the first rotating rod 1. Specifically, a fixed rod is provided in the placement groove along the axis direction of the first rotating rod 1. The acting rod 13 is sleeved on the fixed rod, and the acting rod 13 can slide up and down on the fixed rod but cannot rotate circumferentially on the fixed rod. A third gear 14 is provided on the acting rod 13. The fifth gear 12 meshes with the third gear 14.

[0065] When the power value of the power module of the drone assembly 15 is greater than the threshold value and it is necessary to form an air outlet between two adjacent rotating blades 4, the fifth gear 12 rotates to move the acting rod 13 upward, as Figure 6 shown. At this time, the fifth gear 12 is driven to rotate by the motor. During the rotation of the fifth gear 12, it drives the sixth gear 10 to rotate through the coaxial rod 11. The sixth gear 10 acts on the second ring 8, causing the second ring 8 to rotate circumferentially. Thus, the first gear 7 drives the rotating blade 4 to rotate through the rotating shaft 5, forming an air outlet between two adjacent rotating blades 4.

[0066] When the power value of the power module of the drone assembly 15 is less than or equal to the threshold value, the motor has no acting force on the fifth gear 12. At this time, the acting rod 13 moves downward under the action of gravity. During the downward movement of the acting rod 13, it drives the fifth gear 12 to rotate in the reverse direction, as Figure 7As shown, during the reverse rotation of the fifth gear 12, the sixth gear 10 is driven to rotate in the reverse direction through the coaxial rod 11. The sixth gear 10 acts on the second ring 8, causing the second ring 8 to rotate in the reverse direction. As a result, the first gear 7 drives the rotating piece 4 to rotate through the rotating shaft 5, causing two adjacent rotating pieces 4 to come into contact with each other, achieving the function of a parachute.

[0067] In some embodiments, the threshold is 0.

[0068] Therefore, when the drone component runs out of power, the fifth gear 12 loses the driving force of the motor. The actuating rod 13 moves downward under the action of gravity, thereby driving the fifth gear 12 to rotate in the reverse direction. The first gear 7 drives the rotating piece 4 to rotate through the rotating shaft 5, causing two adjacent rotating pieces 4 to come into contact with each other, achieving the function of a parachute.

[0069] Compared with the existing system, when the drone component runs out of power, under the action of the structure of this system, this system automatically adjusts to achieve the function of a parachute, without the need to consume additional electrical energy for adjustment, which is more conducive to flight use.

[0070] Embodiment 5

[0071] On the basis of the above embodiment, an insect attracting lamp 6 is provided at the upper end of the first rotating rod 1.

[0072] The insect killing unit includes a collection funnel 17, and a high-voltage electric shock net module is provided on the collection funnel 17.

[0073] A negative pressure collection bag 18 is provided below the collection funnel 17.

[0074] Among them, the drone component of this system can adopt common aircraft on the market. The drone component includes a power source for supplying power to the drone component, the high-voltage electric shock net module, the rotation of the first rotating rod, and the rotation of the fifth gear 12.

[0075] The high-voltage electric shock net module is arranged on the arc-shaped side surface of the collection funnel 17. The collection funnel 17 is vertically arranged below the drone component, and the large head end of the drone component faces upward. The small head end of the collection funnel 17 faces downward and is connected to the negative pressure collection bag 18. The pests killed by the high-voltage electric field are collected into the negative pressure collection bag under the action of the negative pressure collection bag. The negative pressure collection bag sucks the pests killed by the high-voltage electric field into the sealed bag through the principle of negative pressure attraction. The negative pressure collection bag adopts the existing technology.

[0076] The high-voltage electric shock net module is electrically connected to the drone component and kills pests through a high-voltage resonance circuit. Specifically, the high-voltage electric shock net module kills pests through a high-voltage resonance circuit, which is an existing technology.

[0077] In some embodiments, a landing gear 19 is provided at the large end of the collection funnel 17, which can not only maintain balance but also protect the drone components during landing.

[0078] In some embodiments, an ultrasonic generator 16 is also provided on the drone component 15, and the ultrasonic generator adopts Doppler ultrasonic technology. As a high-frequency and high-intensity invisible sound wave, the frequency of ultrasonic wave exceeds the highest frequency of 20 kHz that humans can hear. This characteristic enables ultrasonic waves to generate mechanical vibrations. The core idea is to utilize the high-frequency vibration characteristics of ultrasonic waves to generate strong ultrasonic wave interference with different frequencies for different pests, thereby achieving the effect of suppressing, killing, or expelling pests. When the system needs to expel pests, the ultrasonic generator can be directly used to further kill or expel pests.

[0079] During actual use, the operator controls the drone component 15 to fly the insecticidal unit and several rotating blades loaded thereon at high altitude. Pests are attracted and approach the insecticidal unit through the induction of the long-distance insect attracting lamp 6. During the approaching process, the several rotating blades rotate to generate spiral wind. The approaching flying insects are adsorbed into the system under the action of the spiral wind, so that the flying insects further enter the insecticidal unit. And under the action of the air extraction component of the insecticidal unit, the flying insects are further drawn into the insecticidal unit, and the high-voltage resonance circuit is used to kill pests.

[0080] When the system does not need to fly, the ultrasonic generator can be directly used to further kill or expel pests.

[0081] Among them, the air extraction component is a structure that generates air flow through mechanical or electrical drive to achieve air suction. The air extraction component is an existing structure, such as a fan device. The air extraction component extracts the air above into the collection funnel 17 below.

[0082] All the power required by this system is supplied by the drone component.
