Description

Technical Field

[0001] The present invention relates to the technical field of multi-rotor aircraft, and specifically to a portable mine-laying drone. Background Art

[0002] As a type of aircraft, a mine-laying drone can perform mine-laying operations by combining special usage requirements for drones. The mine-laying drone can quickly reach the designated area, is not restricted by terrain, and can complete large-area mine-laying in a short time. Compared with manual mine-laying, it greatly shortens the mine-laying time and improves the efficiency of combat or mission execution.

[0003] When a mine-laying drone is in use, mines are mounted on both sides below the seat. The weight of a single mine can account for 5%-10% of the total weight. Due to the existence of the weight of the mine itself, after the unilateral mine is dropped, the center of gravity of the drone will shift towards the non-dropped side, increasing the risk of roll and pitch moment imbalance during mine-laying and feeding, and affecting the subsequent stable mine-laying operation. Therefore, we propose a portable mine-laying drone. Summary of the Invention

Detailed implementation manners

[0035] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0036] Embodiment 1

[0037] Please refer to Figures 1 - 12 , the portable mine-laying drone in the figure includes a base 101, rotors 102 for assisting flight are installed around the base 101, and a mounting seat 103 is arranged below the base 101;

[0038] It should be noted here that: the rotors 102 assist the drone in flying. As a conventional technical means on the drone, the working principle and operation method of the rotors 102 will not be elaborated here;

[0039] It also includes:

[0040] An installation component, which is arranged between the mounting seat 103 and the bottom of the base 101 to assist in the installation and disassembly of the mounting seat 103;

[0041] A mine-laying and feeding component, which is arranged below the mounting seat 103 for mine-laying and feeding, and two groups of mine-laying and feeding components are symmetrically arranged below the mounting seat 103;

[0042] A discharge control component, which is arranged on the mine-laying and feeding component to assist in the discharge control during the mine-laying process;

[0043] And a counterweight component, which is arranged between the two groups of mine-laying and feeding components to prevent the drone from tilting after feeding;

[0044] It should be noted here that: during the process of using the mine-laying drone for mine-laying operations, through the mutual cooperation of the installation component, the limiting component and the pulling component, the mounting seat 103 and the bottom of the base 101 are quickly installed and disassembled, which is more convenient for the carrying and storage operations when the drone is in use. Moreover, during the mine-laying and feeding process, through the counterweight component, after unilateral mine-laying and feeding, the center of gravity moment on the feeding side is increased, thereby effectively reducing the degree of deviation of the overall center of gravity of the drone caused by the mine-laying on the unilateral storage cylinder 601, so that the center of gravity of the drone remains in a relatively stable position and maintains the stability of the flight attitude.

[0045] Preferably, the mine-laying and feeding component includes a storage cylinder 601. The upper end of the storage cylinder 601 is connected and fixed to the mounting seat 103 through a fixing rod 602. Multiple groups of mines are stacked inside the storage cylinder 601, and the shape of the mines is matched with the internal cavity of the storage cylinder 601;

[0046] It should be noted here that: through the storage cylinder 601, it is convenient to assist in the storage of mines. Through the mutual matching of the shape of the mines and the internal cavity of the storage cylinder 601, it is convenient for the stable downward movement of the mines.

[0047] Preferably, the discharging control assembly includes two sets of square sliding grooves 701 formed on the material storage cylinder 601. A first square baffle 702 and a second square baffle 703 are respectively slidably connected to the two sets of square sliding grooves 701. The second square baffle 703 is located above the first square baffle 702. The first square baffle 702 is used to abut against the bottom of the mine at the lowermost part inside the material storage cylinder 601 to block it. The second square baffle 703 is used to abut against the bottom of the adjacent mine inside the material storage cylinder 601. And the first square baffle 702 and the second square baffle 703 are arranged in a staggered state. A control box 704 is installed outside the material storage cylinder 601. The first square baffle 702 and the second square baffle 703 are located inside the control box 704. A driving assembly for driving the first square baffle 702 and the second square baffle 703 is arranged on the control box 704;

[0048] It should be noted here that: through the mutual cooperation of the driving assembly and the rotating assembly, the first square baffle 702 and the second square baffle 703 are driven. During the driving process, the first square baffle 702 shrinks towards the inside of the control box 704 while the second square baffle 703 extends towards the inside of the material storage cylinder 601. At this time, the first square baffle 702 no longer abuts against the bottom of the mine at the lowermost part inside the material storage cylinder 601, so that the mine at the lowermost part inside the material storage cylinder 601 falls from the material storage cylinder 601 under the action of gravity, completing the mine-laying operation. And through the extension of the second square baffle 703, it abuts against the bottom of the mine at the adjacent position, realizing the operation of only dropping one mine at a time. After the mine dropping is completed, through transmission, the second square baffle 703 shrinks towards the inside of the control box 704 while the first square baffle 702 extends towards the inside of the material storage cylinder 601. At this time, the first square baffle 702 abuts against the mine at the lowermost part inside the material storage cylinder 601, facilitating the subsequent single mine dropping operation.

[0049] Preferably, the driving assembly includes a gear 801 and two sets of racks 802 arranged inside the control box 704. The gear 801 is centrally arranged between the two sets of racks 802 and meshes with the two sets of racks 802. The two sets of racks 802 are respectively fixed to the first square baffle 702 and the second square baffle 703. A rotating assembly for rotating the gear 801 is installed on the control box 704;

[0050] It should be noted here that: through the rotating assembly, the gear 801 is rotated. During the rotation of the gear 801, through the interaction between the gear 801 and the two sets of racks 802, the first square baffle 702 and the second square baffle 703 are moved.

[0051] Preferably, the rotating assembly includes a mounting shaft 901 rotatably connected to the control box 704, a gear 801 is centrally fixed on the mounting shaft 901, and a driving motor 902 for driving the mounting shaft 901 is installed on the control box 704;

[0052] It should be noted here that: through the driving action of the driving motor 902, the gear 801 on the mounting shaft 901 rotates.

[0053] Preferably, the counterweight assembly includes a gravity block 1001 arranged inside the storage cylinder 601, and the gravity block 1001 abuts against the upper side of the uppermost landmine. The outer shape of the gravity block 1001 is matched with the internal cavity of the storage cylinder 601;

[0054] It should be noted here that: by matching the outer shape of the gravity block 1001 with the internal cavity of the storage cylinder 601, the movement of the gravity block 1001 is guided;

[0055] A slot 1002 is formed in the storage cylinder 601. A connecting rod 1003 is arranged inside the slot 1002. One end of the connecting rod 1003 is located inside the storage cylinder 601 and is fixed to the gravity block 1001. The other end of the connecting rod 1003 is located outside the storage cylinder 601 and is fixed with a connecting plate 1004. A vertical plate 1005 is fixed at one end of the connecting plate 1004. A square counterweight box 1006 is centrally arranged between two storage cylinders 601. The inside of the square counterweight box 1006 is filled with a counterweight liquid. The bottom of the square counterweight box 1006 is slidably connected with two mounting brackets 1007 through a sliding assembly. Two mounting plates 1008 are rotatably connected to the two mounting brackets 1007 through pin shafts. One ends of the two mounting plates 1008 are respectively fixed to the upper ends of the two vertical plates 1005;

[0056] It should be noted here that when the mine storage cylinders 601 on one side are used for mine dropping, the number of mines inside the two groups of mine storage cylinders 601 is different. At this time, there is a height difference between the gravity blocks 1001 inside the two groups of mine storage cylinders 601. Due to the effect of the height difference and the connection of the connecting rod 1003, the connecting plate 1004, the vertical plate 1005, the mounting plate 1008 and the mounting frame 1007, the square counterweight box 1006 is pulled to tilt towards the mine storage cylinder 601 on the side with fewer mines, and the square counterweight box 1006 tilts towards the mine storage cylinder 601 on the mine dropping side. Subsequently, during the process of mine laying and feeding, another group of mine storage cylinders 601 is used for single mine feeding operation to make the number of mines inside the two groups of mine storage cylinders 601 the same. At this time, there is no height difference between the two groups of gravity blocks 1001. Through the connection of the connecting rod 1003, the connecting plate 1004, the vertical plate 1005, the mounting plate 1008 and the mounting frame 1007 and the resetting effect of the sliding assembly on the two mounting plates 1008 and the mounting frame 1007, the square counterweight box 1006 is reset and rotated to a horizontal state, keeping the center of gravity of the entire unmanned aerial vehicle unchanged and facilitating the stable flight and mine laying operation of the mine laying unmanned aerial vehicle;

[0057] It is worth noting here that the counterweight liquid is water liquid, which has strong fluidity and low price.

[0058] The sliding assembly includes a mounting groove 1101 opened at the bottom of the square counterweight box 1006. Two linkage plates 1102 are arranged inside the mounting groove 1101. The two mounting frames 1007 are respectively fixed to the two linkage plates 1102. A plurality of round rods 1103 are slidably connected to the two linkage plates 1102. The round rods 1103 are fixed inside the mounting groove 1101. A second spring 1104 for abutting and driving the linkage plate 1102 is sleeved on the outer side of each round rod 1103;

[0059] It should be noted here that through the connection of the linkage plate 1102 and the sliding of the round rod 1103, the sliding connection of the mounting frame 1007 at the bottom of the square counterweight box 1006 is assisted. Through the second spring 1104, it is convenient to reset the slid linkage plate 1102 and the mounting frame 1007.

[0060] Preferably, the installation component includes a positioning rod 201 fixed to the lower end of the machine base 101. A positioning cylinder 202 for sleeved connection with the positioning rod 201 is fixed to the upper end of the mounting base 103. A limiting component for assisting in limiting after sleeved installation is arranged between the positioning cylinder 202 and the positioning rod 201. There are multiple groups of limiting components, and the multiple groups of limiting components are arranged in a circular array state. The limiting component includes a limiting groove 301 opened on the positioning rod 201. A limiting plate 303 for inserting and limiting with the limiting groove 301 is slidably connected to the positioning cylinder 202. An inclined surface 304 for abutting and transmitting with the end of the positioning rod 201 is opened on the upper end of the limiting plate 303. A U-shaped frame 302 is fixed to the outside of the positioning cylinder 202. A telescopic component for telescopically connecting the limiting plate 303 and a pulling component for pulling the limiting plate 303 are arranged on the U-shaped frame 302;

[0061] It should be noted here that: Push the positioning cylinder 202 towards the positioning rod 201. During the pushing process, the inclined surfaces 304 on each limiting plate 303 abut against the end of the positioning rod 201. During the abutting process, the limiting plate 303 is forced to contract. As the positioning cylinder 202 and the positioning rod 201 are pushed closer, when the limiting plate 303 is aligned with the limiting groove 301, through the telescopic component, the limiting plate 303 is pushed into the inside of the limiting groove 301. Through the interaction between the limiting plate 303 and the limiting groove 301, the connected positioning cylinder 202 and positioning rod 201 are limited to assist in installation.

[0062] Preferably, the telescopic component includes multiple groups of sleeves 401 fixed to the U-shaped frame 302. A sliding rod 402 is slidably connected to the sleeve 401. One end of the sliding rod 402 is fixed to the limiting plate 303. A first spring 403 is sleeved on the outside of the sleeve 401. The two ends of the first spring 403 respectively abut against the U-shaped frame 302 and the limiting plate 303;

[0063] It should be noted here that: Through the sleeve 401 and the sliding rod 402, it is convenient to assist in the telescopic connection of the limiting plate 303. Through the first spring 403, it is convenient to push the reset of the limiting plate 303 after the contraction movement.

[0064] Preferably, the pulling component includes a pull rod 501 slidably connected to the U-shaped frame 302. One end of the pull rod 501 is fixed to the limiting plate 303. A pull pin 502 is fixed to the other end of the pull rod 501;

[0065] It should be noted here that: When it is necessary to disassemble the mounting base 103 and the machine base 101, pull the pull rod 501 through the pull pin 502, so that the limiting plate 303 slides out of the limiting groove 301 to release the limit. At this time, the mounting base 103 and the machine base 101 can be disassembled by moving them away from each other.

[0066] In this scheme: portable mine-laying drone, including the following steps:

[0067] During the mine-laying operation using the mine-laying drone, the mounting seat 103 cooperates with the mounting assembly, the limit assembly and the pulling assembly to quickly install and disassemble the mounting seat 103 and the bottom of the base 101. The installation and disassembly between the mounting seat 103 and the base 101 makes it easier to carry and store the drone when in use. After the mounting seat 103 and the base 101 are installed, multiple groups of mines to be dropped are stored inside the two groups of storage barrels 601. During the mine-laying process, the number of mines inside the two groups of storage barrels 601 is the same. The same number of mines inside the two groups of storage barrels 601 prevents the center of gravity of the drone from shifting during the mine-laying flight, facilitating stable mine-laying operations by the mine-laying drone.

[0068] The drone is driven by the multiple rotors 102 on the base 101 to fly to a designated location for mine laying. During the mine laying process, the first square baffle 702 and the second square baffle 703 are driven by the cooperation between the driving assembly and the rotating assembly. During the driving process, the first square baffle 702 is retracted toward the inside of the control box 704 and the second square baffle 703 is extended toward the inside of the storage barrel 601 (see FIG. Figure 8 The first square baffle 702 no longer blocks the bottom of the mine at the bottom of the storage barrel 601, so that the mine at the bottom of the storage barrel 601 falls from the storage barrel 601 under the action of gravity, and the mine-laying operation is completed. The second square baffle 703 extends to abut against the bottom of the mine at the adjacent position, so that only one mine is dropped at a time. After the mine dropping is completed, the second square baffle 703 is retracted toward the inside of the control box 704 through transmission, while the first square baffle 702 extends toward the inside of the storage barrel 601 (see FIG. Figure 7 At this time, the first square baffle 702 is used to offset the mine at the bottom of the storage barrel 601, so as to facilitate the subsequent mines to continue the single placement operation;

[0069] During the process of mine laying and feeding, since the gravity block 1001 abuts against the uppermost mine inside the storage cylinder 601, during the mine laying process, the gravity block 1001 moves downward synchronously with the outward release of the mine. When the mines are released from one-sided storage cylinder 601, the number of mines inside the two groups of storage cylinders 601 is different. At this time, there is a height difference between the gravity blocks 1001 inside the two groups of storage cylinders 601. Due to the effect of the height difference and the connection of the connecting rod 1003, the connecting plate 1004, the vertical plate 1005, the mounting plate 1008 and the mounting frame 1007, the square counterweight box 1006 is pulled to tilt towards the storage cylinder 601 on the side with fewer mines, and the square counterweight box 1006 tilts towards the storage cylinder 601 on the mine-throwing side (see the state of Figure 11 ). This is equivalent to moving the center of gravity of the liquid in the square counterweight box 1006 to this side. Since the liquid is fluid, it can redistribute inside the square counterweight box 1006, increasing the weight on this side. According to the lever principle, when the force arm remains unchanged, increasing the force on this side can increase the moment of this side about the center of gravity, thereby effectively reducing the degree of deviation of the overall center of gravity of the unmanned aerial vehicle after the mine feeding of the one-sided storage cylinder 601, keeping the center of gravity of the unmanned aerial vehicle at a relatively stable position and maintaining the stability of the flight attitude. Subsequently, during the process of mine laying and feeding, another group of storage cylinders 601 is used for a single mine feeding operation, so that the number of mines inside the two groups of storage cylinders 601 is the same. At this time, there is no height difference between the two groups of gravity blocks 1001. Through the connection of the connecting rod 1003, the connecting plate 1004, the vertical plate 1005, the mounting plate 1008 and the mounting frame 1007 and the resetting effect of the sliding assembly on the two mounting plates 1008 and the mounting frame 1007, the square counterweight box 1006 is reset and rotated to a horizontal state (see the states of Figure 9 and Figure 10 ), keeping the center of gravity of the entire unmanned aerial vehicle from shifting, which is convenient for the stable flight and mine laying operation of the mine laying unmanned aerial vehicle.
