Description
Technical Field
[0001] The present invention relates to the technical field of plant protection drones, in particular to a multi-rotor plant protection drone with anti-swaying and liquid storage. Background Art
[0002] Plant protection drones, also known as agricultural drones, are unmanned aerial vehicles specifically designed for use in agriculture. They are often equipped with advanced systems that not only precisely and evenly apply pesticides, fertilizers, and other agricultural chemicals to crops, but also enable the transportation of liquid pesticides. This technology significantly improves the efficiency and accuracy of pesticide application, reduces chemical usage, minimizes environmental impact, and helps improve crop yields and quality. Plant protection drones are easy to operate and highly automated, significantly reducing farmers' workload and making them a significant innovation in modern agricultural technology.
[0003] In current agricultural drones, for storing liquid medicine, a liquid storage tank is usually installed at the bottom of the drone to transport, deliver or spray the liquid medicine. However, during transportation, the flight trajectory of the drone does not always fly in a straight line at a constant speed. This causes the liquid medicine in the liquid storage tank to shake during flight, thereby affecting the flight stability of the drone. At the same time, in order to ensure the airtightness of the liquid storage tank and prevent liquid medicine leakage, the liquid storage tank is usually molded in one piece, with only a small infusion hole reserved. This greatly increases the time required to transport the liquid medicine into the liquid storage tank, which is not conducive to improving work efficiency. Summary of the Invention
[0004] The present invention provides a multi-rotor plant protection drone with anti-swaying and liquid storage, which solves the problems mentioned in the above background technology.
[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: a multi-rotor plant protection drone with anti-sway liquid storage, comprising a mounting frame, a propeller fixedly mounted on the mounting frame via a connecting rod, a bracket fixedly connected to the bottom of the mounting frame, a connecting frame symmetrically fixedly connected to the outer side of the bottom of the mounting frame, a lithium battery fixedly mounted on the top of the bracket, and the lithium battery is arranged below the mounting frame, and further comprising:
[0006] A liquid storage mechanism, the liquid storage mechanism is provided below the lithium battery and is also provided on the inner side of the bracket, and is used to store liquid medicine;
[0007] an anti-sway mechanism, the anti-sway mechanism being fixedly mounted inside the liquid storage mechanism and being used to suppress swaying of the liquid medicine inside the liquid storage mechanism;
[0008] The liquid storage mechanism includes a connecting block, which is fixedly connected to the bottom of the connecting frame. Four connecting blocks are provided. The inner surface of the connecting block is fixedly connected to an outer frame. The outer frame is in a rectangular shape. The interior of the outer frame is set to be hollow. The bottom of the outer frame is set to be open. A liquid storage box is slidably inserted into the interior of the outer frame through the bottom opening. The liquid storage box is fixedly installed between the outer frame by bolts. A sealing plate is squeezed and fastened on the upper surface of the liquid storage box. The bottom surface of the sealing plate is set to a rubber plate. The upper surface of the sealing plate is symmetrically fixedly connected with an elastic telescopic rod, and the end of the elastic telescopic rod away from the sealing plate is fixedly connected to the inner upper surface of the outer frame.
[0009] Preferably, the anti-sway mechanism includes an isolation plate, which is fixedly connected to the inner surface of the liquid storage box, and the isolation plate and the sealing plate are arranged perpendicular to each other, and a plurality of isolation plates are arranged at fixed intervals in the liquid storage box, and a connecting hole is opened through the bottom side of the liquid storage box, and a plurality of connecting holes are opened at fixed intervals at the bottom of the same isolation plate. If it is necessary to transport the liquid medicine, the liquid storage box can be removed from the outer frame and the liquid medicine can be injected into the liquid storage box. When the liquid medicine is injected, the outer frame can be fastened from the top of the liquid storage box to complete the fixed installation. When the outer frame is fastened to the liquid storage box, the top of the liquid storage box gradually contacts the bottom surface of the sealing plate. At this time, as the outer frame and the liquid storage box are further fastened, the liquid storage box will squeeze the sealing plate, causing the elastic telescopic rod on the upper surface of the sealing plate to be squeezed, and then the bottom surface of the sealing plate is firmly attached to the upper surface of the liquid storage box, thereby completing the sealing of the liquid storage box.
[0010] Preferably, a mounting groove is provided through the middle side surface of the isolation plate, the mounting groove is circular, a mounting ring is provided on the outside of the mounting groove, the mounting ring is symmetrically fixedly connected to the middle side surfaces at both ends of the isolation plate, and the mounting ring is buckled and arranged on the outer edge of the mounting groove.
[0011] Preferably, the inner surface of the mounting ring is fixedly connected to a corrugated ring, the corrugated ring is configured as an elastic rubber ring, the cross-section of the corrugated ring is configured obliquely, the outer end of the corrugated ring is fixedly connected to an adapter plate, the adapter plate is configured as a circular plate, the outer surface of the adapter plate is fixedly connected to a drive plate, and the drive plate is configured on the outside of the mounting ring.

[0013] Preferably, a functional groove is opened inside the bottom end of the isolation plate, and the functional groove is connected to the installation groove. The interior of the functional groove is horizontally slidably connected to a movable plate, and the movable plate is initially located in the center of the functional groove. The upper surface of the movable plate is set to an arc shape, and the upper surface of the movable plate is fixedly connected to a support rod.

[0014] Preferably, a slide groove is provided under the movable plate, and the slide groove is opened on the inner side of the connecting hole, and the slide groove is set to a notch shape, and the slide groove is symmetrically opened on both sides of the bottom inner surface of the isolation plate, and a sealed block is elastically slidably connected in the slide groove, and the inner surface of the sealed block is set to an inclined surface. When the drone is in flight, due to changing direction, acceleration or deceleration, the medicine in the liquid storage box cannot adapt to the flight rhythm of the drone in the first time due to the existence of inertia force, and then the driving plate on the isolation plate will be squeezed by the inertia force, prompting the driving plate to move into the installation groove. As the driving plate moves, the corrugated ring will be deformed, and the power plate will be squeezed by the adapter plate, causing the power plate to produce a small displacement. When the power plate moves, it will drive the movable plate below it to move back and forth horizontally in the functional groove through the support rod, and then the movable plate will generate an extrusion force on the sealed block in the slide groove, prompting the sealed block to slide downward along the slide groove, and finally blocking the connecting hole, so that the medicine between the isolation plates cannot be connected.
[0015] Preferably, a first elastic telescopic ring is symmetrically fixedly connected to the side surfaces at both ends of the liquid storage box, a second elastic telescopic ring is provided on the outer side of the first elastic telescopic ring, the second elastic telescopic ring is symmetrically fixedly connected to the side surfaces at both ends of the outer frame, and the internal cavity of the first elastic telescopic ring is connected to the internal cavity of the bellows.
[0016] Preferably, air pressure grooves are provided in the two end walls of the outer frame, the air pressure grooves are connected to the internal cavity of the first elastic telescopic ring, and an air pipe is provided on the top of the air pressure groove, the air pipe symmetrically passes through and is fixedly connected to the top side of the outer frame, and the end of the air pipe away from the side of the outer frame is fixedly connected to an extrusion bag, and the extrusion bag is fixedly connected to the middle upper surface of the sealing plate. When the liquid storage box squeezes the sealing plate during installation, as the distance between the sealing plate and the inner surface of the top of the outer frame decreases, the extrusion bag on the upper surface of the sealing plate will be squeezed, so that the extrusion bag will transport the internal air pressure to the air pressure groove through the air pipe. Since the air pressure groove is connected to the internal cavity of the first elastic telescopic ring, the extrusion bag will transport its internal air pressure to the first elastic telescopic ring when it is squeezed, causing the first elastic telescopic ring to expand, and gradually squeeze the second elastic telescopic ring, forcing the second elastic telescopic ring to contract.
[0017] The present invention provides a multi-rotor plant protection drone with anti-swaying liquid storage. It has the following beneficial effects:
[0018] 1. This anti-sway liquid storage multi-rotor agricultural drone can achieve the effect of sealing the liquid storage box by elastically installing the sealing plate, which not only greatly reduces the complexity of installation, but also allows the top of the liquid storage box to be fully open, thereby greatly increasing the speed of liquid injection and greatly improving work efficiency. Moreover, since multiple isolation plates are provided in the liquid storage box, the liquid in the liquid storage box can be stored in layers, which greatly reduces the inertial force of the liquid during flight, greatly reduces the impact of the inertia of the liquid on the flight of the drone, and ensures that the drone can work better. By opening a connecting hole at the bottom of the isolation plate, it ensures that the liquid in the liquid storage box is in a connected state, so that the liquid in the liquid storage box is at the same horizontal plane when the drone is flying steadily, which is convenient for taking out and spraying the liquid.
[0019] 2. This anti-sway liquid storage multi-rotor agricultural drone can seal the connecting holes of the isolation plate when the drone changes direction, accelerates or decelerates, thereby isolating the connection of the liquid medicine, forcing the liquid medicine between the isolation plates to be unable to be connected and transported, increasing the inertial force and affecting the flight stability of the drone, thereby further improving the working efficiency of the drone. When the drone flight tends to be stable, the power plate resets, driving the sealing block to reset in the slide slot, so that the liquid medicine is connected, and the amount of liquid medicine between the isolation plates is adjusted to be consistent, which is convenient for taking the liquid medicine, thereby further improving the working efficiency.
[0020] 3. In this anti-sway liquid storage multi-rotor agricultural drone, when the second elastic telescopic ring contracts, its internal air pressure will be transmitted to the bellows, thereby causing the bellows to expand outward, that is, the driving plates on both sides of the isolation plate will move outward a certain distance, which can not only increase the cavity area between the isolation plates to cause the horizontal surface of the liquid to rise and reduce the inertial force of the liquid, but also more sensitively squeeze the power plate to cause the power plate to move more sensitively, further improving the isolation effect of the liquid between the isolation plates when the drone changes speed, that is, further reducing the inertial force of the liquid itself, greatly improving the working efficiency of the drone, and ensuring the working stability of the drone.

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0031] First embodiment: Figures 1 to 8 As shown, the present invention provides a technical solution: a multi-rotor plant protection drone with anti-sway liquid storage, including a mounting frame 1, a propeller 2 fixedly mounted on the mounting frame 1 through a connecting rod, a bracket 3 fixedly connected to the bottom of the mounting frame 1, a connecting frame 4 symmetrically fixedly connected to the outer side of the bottom of the mounting frame 1, a lithium battery 5 fixedly mounted on the top of the bracket 3, and the lithium battery 5 is arranged below the mounting frame 1, and further comprising:
[0032] The liquid storage mechanism 6 is provided below the lithium battery 5 and is also provided on the inner side of the bracket 3. The liquid storage mechanism 6 is used to store liquid medicine.
[0033] The anti-sway mechanism 7 is fixedly installed inside the liquid storage mechanism 6 and is used to suppress the shaking of the liquid medicine inside the liquid storage mechanism 6;
[0034] The liquid storage mechanism 6 includes a connecting block 61, which is fixedly connected to the bottom of the connecting frame 4. There are four connecting blocks 61. The inner surface of the connecting block 61 is fixedly connected to an outer frame 62. The outer frame 62 is in a rectangular shape. The interior of the outer frame 62 is set to be hollow. The bottom of the outer frame 62 is set to be open. The interior of the outer frame 62 is slidably inserted with a liquid storage box 63 through the bottom opening. The liquid storage box 63 is fixedly installed between the outer frame 62 by bolts. A sealing plate 64 is squeezed and fastened on the upper surface of the liquid storage box 63. The bottom surface of the sealing plate 64 is set to a rubber plate. The upper surface of the sealing plate 64 is symmetrically fixedly connected with an elastic telescopic rod 65. The end of the elastic telescopic rod 65 away from the sealing plate 64 is fixedly connected to the inner upper surface of the outer frame 62.
[0035] The anti-sway mechanism 7 includes an isolation plate 71, which is fixedly connected to the inner surface of the liquid storage box 63. The isolation plate 71 and the sealing plate 64 are arranged perpendicular to each other. A plurality of isolation plates 71 are arranged at fixed intervals in the liquid storage box 63. A connecting hole 72 is opened through the bottom side of the liquid storage box 63, and a plurality of connecting holes 72 are opened at fixed intervals at the bottom of the same isolation plate 71.
[0036] During operation, if it is necessary to transport the medicine liquid, the liquid storage box 63 can be removed from the outer frame 62 and the medicine liquid can be injected into the liquid storage box 63. When the medicine liquid is injected, the outer frame 62 can be buckled from the top of the liquid storage box 63 to complete the fixed installation. When the outer frame 62 is buckled on the liquid storage box 63, the top of the liquid storage box 63 gradually contacts the bottom surface of the sealing plate 64. At this time, as the outer frame 62 and the liquid storage box 63 are further buckled, the liquid storage box 63 will squeeze the sealing plate 64, causing the elastic telescopic rod 65 on the upper surface of the sealing plate 64 to be squeezed, and then the bottom surface of the sealing plate 64 is firmly attached to the upper surface of the liquid storage box 63, thereby completing the sealing of the liquid storage box 63. By elastically installing the sealing plate 64, it can be achieved The sealing effect of the installation of the liquid storage box 63 not only greatly reduces the complexity of installation, but also allows the top of the liquid storage box 63 to be fully open, thereby greatly improving the speed of liquid medicine injection and greatly improving work efficiency. Moreover, since a plurality of isolation plates 71 are provided in the liquid storage box 63, the liquid medicine in the liquid storage box 63 is stored in layers, which greatly reduces the inertia force of the liquid medicine during the flight of the drone, greatly reduces the impact of the inertia of the liquid medicine on the flight of the drone, and ensures that the drone can work better. By opening a connecting hole 72 at the bottom of the isolation plate 71, it is ensured that the liquid medicine in the liquid storage box 63 is in a connected state, so that the liquid medicine in the liquid storage box 63 is at the same horizontal plane when the drone is flying steadily, which is convenient for taking out and spraying the liquid medicine.
[0037] Second embodiment: Figures 1 to 8As shown, a mounting groove 73 is provided through the middle side surface of the isolation plate 71. The mounting groove 73 is circular. A mounting ring 74 is provided on the outside of the mounting groove 73. The mounting ring 74 is symmetrically fixedly connected to the middle side surfaces at both ends of the isolation plate 71. The mounting ring 74 is buckled and set on the outer edge of the mounting groove 73.
[0038] The inner surface of the mounting ring 74 is fixedly connected to a corrugated ring 75 , which is configured as an elastic rubber ring. The cross section of the corrugated ring 75 is configured obliquely. The outer end of the corrugated ring 75 is fixedly connected to an adapter plate 76 , which is configured as a circular plate. The outer surface of the adapter plate 76 is fixedly connected to a drive plate 77 , which is configured on the outside of the mounting ring 74 .
[0039] The inner surface of the adapter plate 76 is fixedly connected to a bellows 78 , which is elastic. The side of the bellows 78 away from the adapter plate 76 is fixedly connected to a power plate 79 , which is circular and is set in the middle of the mounting groove 73 .
[0040] A functional groove 710 is opened inside the bottom end of the isolation plate 71, and the functional groove 710 is connected to the installation groove 73. The interior of the functional groove 710 is horizontally slidably connected to a movable plate 711. The movable plate 711 is initially located in the center of the functional groove 710. The upper surface of the movable plate 711 is set to be arc-shaped. The upper surface of the movable plate 711 is fixedly connected to a support rod 712. A plurality of support rods 712 are arranged at fixed intervals around the arc surface of the movable plate 711, and the top of the support rod 712 is fixedly connected to the bottom of the power plate 79.
[0041] A slide groove 713 is provided below the movable plate 711. The slide groove 713 is opened on the inner side of the connecting hole 72. The slide groove 713 is set to a notch type. The slide groove 713 is symmetrically opened on both sides of the bottom inner surface of the isolation plate 71. A sealed block 714 is elastically slidably connected in the slide groove 713, and the inner surface of the sealed block 714 is set to an inclined surface.
[0042] During operation, when the drone is in flight, the liquid in the liquid storage box 63 cannot adapt to the flight rhythm of the drone in the first time due to the change of direction, acceleration or deceleration due to the existence of inertia, and then the driving plate 77 on the isolation plate 71 is squeezed by the inertia, prompting the driving plate 77 to move into the installation groove 73. As the driving plate 77 moves, the corrugated ring 75 is deformed, and the power plate 79 is squeezed through the adapter plate 76, causing the power plate 79 to have a small displacement. When the power plate 79 moves, it drives the moving plate 711 below it to move back and forth horizontally in the functional groove 710 through the support rod 712, and then the sealed block in the slide groove 713 is pressed by the moving plate 711. 714 generates an extrusion force, which prompts the sealed block 714 to slide downward along the slide groove 713, and finally blocks the connecting hole 72, so that the medicine liquid between the isolation plates 71 cannot be connected, that is, when the drone changes direction, accelerates or decelerates, the connecting hole 72 of the isolation plate 71 is closed, isolating the medicine liquid from being connected, forcing the medicine liquid between the isolation plates 71 to be unable to be connected and transported, increasing the inertial force and affecting the flight stability of the drone, further improving the work efficiency of the drone. When the drone flight tends to be stable, the power plate 79 is reset, driving the sealed block 714 to reset in the slide groove 713, so that the medicine liquid is connected, and the amount of medicine liquid between the isolation plates 71 is adjusted to be consistent, which is convenient for taking the medicine liquid, further improving the work efficiency.
[0043] The third embodiment: Figures 1 to 8 As shown, the first elastic telescopic ring 715 is symmetrically fixedly connected to the side surfaces of both ends of the liquid storage box 63, and the second elastic telescopic ring 716 is arranged opposite the outer side of the first elastic telescopic ring 715. The second elastic telescopic ring 716 is symmetrically fixedly connected to the side surfaces of both ends of the outer frame 62, and the internal cavity of the first elastic telescopic ring 715 is connected to the internal cavity of the bellows 78.
[0044] An air pressure groove 717 is provided in the two end walls of the outer frame 62, and the air pressure groove 717 is connected to the internal cavity of the first elastic telescopic ring 715. The top of the air pressure groove 717 is connected to an air pipe 718, and the air pipe 718 is symmetrically passed through and fixedly connected to the top side of the outer frame 62. The end of the air pipe 718 away from the side of the outer frame 62 is fixedly connected to an extrusion bag 719, and the extrusion bag 719 is fixedly connected to the middle upper surface of the sealing plate 64.
[0045] During operation, when the liquid storage box 63 squeezes the sealing plate 64 during installation, as the distance between the sealing plate 64 and the inner surface of the top of the outer frame 62 decreases, the squeezing bag 719 on the upper surface of the sealing plate 64 will be squeezed, so that the squeezing bag 719 transmits the internal air pressure to the air pressure groove 717 through the air pipe 718. Since the air pressure groove 717 is connected to the internal cavity of the first elastic telescopic ring 715, the squeezing bag 719 will transmit its internal air pressure to the first elastic telescopic ring 715 when squeezed, causing the first elastic telescopic ring 715 to expand and gradually squeeze the second elastic telescopic ring 716, forcing the second elastic telescopic ring 716 to shrink. When the second elastic telescopic ring 716 contracts, the internal air pressure will be transmitted to the bellows 78, thereby causing the bellows 78 to expand outward, that is, the driving plates 77 on both sides of the isolation plate 71 will move outward for a distance, which can not only increase the cavity area occupied between the isolation plates 71, causing the horizontal surface of the medicine to rise and reduce the inertia force of the medicine, but also can more sensitively squeeze the power plate 79 to cause the movement of the power plate 79 to be more sensitive, further improving the isolation effect of the medicine between the isolation plates 71 when the drone changes speed, that is, further reducing the inertia force of the medicine itself, greatly improving the working efficiency of the drone, and ensuring the working stability of the drone.
