Description

Technical Field

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

[0002] As a type of aircraft, mine-laying drones can be used to carry out mine-laying operations in combination with the special use requirements of drones. Mine-laying drones can quickly reach designated areas, are not restricted by terrain, and can complete large-area mine laying in a short period of time. Compared with manual mine laying, mine-laying drones greatly shorten the mine-laying time and improve the efficiency of combat or mission execution.

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

DETAILED DESCRIPTION

[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings.

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.

[0036] Example 1

[0037] See also Figures 1-12 The portable mine-laying UAV shown in the figure includes a base 101, a rotor 102 for assisting flight is installed around the base 101, and a mounting base 103 is provided below the base 101;

[0038] It should be noted that the rotor 102 is used to assist the drone in flight. The rotor 102 is a conventional technical means on the drone, and its working principle and operation method are not described in detail here.

[0039] Also includes:

[0040] The mounting assembly is provided between the mounting base 103 and the bottom of the base 101 to assist in the installation and removal of the mounting base 103;

[0041] The mine-laying and feeding components are 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 is provided on the mine-laying and feeding component to assist in the discharge control during the mine-laying process;

[0043] and a counterweight assembly disposed between the two sets of mine-laying and feeding assemblies for preventing the drone from tilting after feeding;

[0044] It should be noted here that: during the mine-laying operation using a mine-laying drone, the mounting seat 103 and the bottom of the machine base 101 can be quickly installed and disassembled through the mutual cooperation of the mounting assembly, the limiting assembly and the pulling assembly, which makes it more convenient for the carrying and storage operation of the drone when in use. Moreover, during the mine-laying and feeding process, through the counterweight assembly, after feeding on one side, the center of gravity torque 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 feeding of mines from the one-sided storage barrel 601, so that the center of gravity of the drone remains in a relatively stable position and the stability of the flight attitude is maintained.

[0045] Preferably, the mine-laying and feeding assembly includes a storage barrel 601, the upper end of the storage barrel 601 is connected and fixed to the mounting seat 103 by a fixing rod 602, and multiple groups of mines are stacked inside the storage barrel 601, and the shape of the mines matches the internal cavity of the storage barrel 601;

[0046] It should be noted that the storage barrel 601 facilitates the storage of auxiliary mines, and the matching arrangement of the outer shape of the mines and the inner cavity of the storage barrel 601 facilitates the stable descending movement of the mines.

[0047] Preferably, the discharging control component includes two groups of square chutes 701 provided on the storage barrel 601, and the two groups of square chutes 701 are respectively slidably connected with a first square baffle 702 and a second square baffle 703, the second square baffle 703 is located above the first square baffle 702, the first square baffle 702 is used to block the bottom of the lowest mine in the storage barrel 601, and the second square baffle 703 is used to block the bottom of the adjacent mines in the storage barrel 601, and the first square baffle 702 and the second square baffle 703 are arranged in a staggered state, and a control box 704 is installed on the outside of the storage barrel 601, the first square baffle 702 and the second square baffle 703 are located inside the control box 704, and the control box 704 is provided with a driving component for driving the first square baffle 702 and the second square baffle 703;

[0048] It should be noted here that: the first square baffle 702 and the second square baffle 703 are driven by the mutual cooperation of the driving component and the rotating component. 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. At this time, 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 is removed from the storage barrel under the action of gravity. 601 falls down to complete the mine-laying operation, and the second square baffle 703 is extended to offset 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, and the first square baffle 702 is extended toward the inside of the storage barrel 601. At this time, the first square baffle 702 offsets the mine at the bottom of the storage barrel 601, which is convenient for the subsequent mines to continue the single dropping operation.

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

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

[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 that the gear 801 on the mounting shaft 901 is rotated by the driving action of the driving motor 902 .

[0053] Preferably, the counterweight assembly includes a gravity block 1001 disposed inside the storage barrel 601, and the gravity block 1001 is against the upper side of the uppermost mine, and the shape of the gravity block 1001 matches the internal cavity of the storage barrel 601;

[0054] It is worth noting that the movement of the gravity block 1001 is guided by matching the shape of the gravity block 1001 with the internal cavity of the storage barrel 601.

[0055] A slot 1002 is provided on the material storage barrel 601, and a connecting rod 1003 is provided inside the slot 1002. One end of the connecting rod 1003 is located inside the material storage barrel 601 and is fixed to the gravity block 1001. The other end of the connecting rod 1003 is located outside the material storage barrel 601 and is fixed with a connecting plate 1004. A vertical plate 1005 is fixed to one end of the connecting plate 1004. A square balancing weight box 1006 is centrally provided between the two groups of material storage barrels 601. The interior of the square balancing weight box 1006 is filled with balancing weight liquid. The bottom of the square balancing weight box 1006 is slidably connected to two groups of mounting frames 1007 through a sliding assembly. Two groups of mounting plates 1008 are rotatably connected to the two groups of mounting frames 1007 through pin shafts. One end of the two groups of mounting plates 1008 is respectively fixed to the upper ends of the two groups of vertical plates 1005;

[0056] It should be noted here that: when the storage barrel 601 on one side is used to drop mines, the number of mines inside the two groups of storage barrels 601 is different. At this time, there is a height difference between the gravity blocks 1001 inside the two groups of storage barrels 601. Due to the effect of the height difference and the connection effect 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 toward the storage barrel 601 on the side with fewer mines, and the square counterweight box 1006 is tilted toward the storage barrel 601 on the mine-dropping side. During the process, another set of storage barrels 601 is used to carry out a single mine feeding operation, so that the number of mines inside the two sets of storage barrels 601 is the same. At this time, there is no height difference between the two sets 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 reset action of the sliding assembly on the two sets of 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 UAV from shifting, facilitating the stable flight mine laying operation of the mine laying UAV.

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

[0058] The sliding assembly includes a mounting groove 1101 provided at the bottom of the square counterweight box 1006. Two sets of linkage plates 1102 are provided inside the mounting groove 1101. Two sets of mounting brackets 1007 are respectively fixed to the two sets of linkage plates 1102. Multiple sets of round rods 1103 are slidably connected to the two sets of linkage plates 1102. The round rods 1103 are fixed inside the mounting groove 1101. The outer side of each set of round rods 1103 is provided with a second spring 1104 for driving the linkage plates 1102 against each other.

[0059] It should be noted here that: through the connecting action of the linkage plate 1102 and the sliding action of the round rod 1103, the auxiliary mounting frame 1007 is slidably connected to the bottom of the square counterweight box 1006, and the second spring 1104 facilitates the reset of the linkage plate 1102 and the mounting frame 1007 after sliding.

[0060] Preferably, the mounting assembly includes a positioning rod 201 fixed to the lower end of the machine base 101, a positioning cylinder 202 for being sleeved and connected to the positioning rod 201 is fixed on the upper end of the mounting seat 103, and a limiting assembly for assisting the sleeve to limit the installation after installation is provided between the positioning cylinder 202 and the positioning rod 201; the limiting assembly is provided with multiple groups, and the multiple groups of limiting assemblies are arranged in a state of an annular array, and the limiting assembly includes a limiting groove 301 provided on the positioning rod 201, a limiting plate 303 for inserting and limiting the limiting groove 301 is slidably connected on the positioning cylinder 202, and an upper end of the limiting plate 303 is provided with an inclined surface 304 for abutting the end of the positioning rod 201 for transmission, a U-shaped frame 302 is fixed to the outer side of the positioning cylinder 202, and a telescopic assembly for telescopically connecting the limiting plate 303 and a pulling assembly for pulling the limiting plate 303 are provided on the U-shaped frame 302;

[0061] It should be noted here that: the positioning cylinder 202 is pushed toward the positioning rod 201. During the pushing process, the inclined surfaces 304 on each group of limiting plates 303 are against the end of the positioning rod 201. During the against-against process, the limiting plates 303 are forced to contract. As the positioning cylinder 202 and the positioning rod 201 are pushed toward each other, when the limiting plates 303 are aligned with the limiting grooves 301, the limiting plates 303 are pushed into the inside of the limiting grooves 301 through the telescopic assembly. Through the interaction between the limiting plates 303 and the limiting grooves 301, the connected positioning cylinder 202 and the positioning rod 201 are limited to assist in installation.

[0062] Preferably, the telescopic assembly includes multiple sets of sleeves 401 fixed on the U-shaped frame 302, with a slide rod 402 slidably connected to the sleeve 401, one end of the slide rod 402 is fixed to the limit plate 303, and a first spring 403 is sleeved on the outer side of the sleeve 401, and the two ends of the first spring 403 are respectively set against the U-shaped frame 302 and the limit plate 303;

[0063] It should be noted that: the sleeve 401 and the slide rod 402 are used to assist the telescopic connection of the limit plate 303, and the first spring 403 is used to facilitate the reset and push of the limit plate 303 after the contraction movement.

[0064] Preferably, the pulling assembly includes a pull rod 501 slidably connected to the U-shaped frame 302, one end of the pull rod 501 is fixed to the limit plate 303, and the other end of the pull rod 501 is fixed with a pulling pin 502;

[0065] It should be noted here that: when the mounting base 103 and the machine base 101 need to be disassembled, the pull pin 502 is used to pull the pull rod 501, so that the limit plate 303 slides out of the limit groove 301 and the limit is released. At this time, the mounting base 103 and the machine base 101 can be moved away from each other for disassembly.

[0066] In this solution: 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 limiting assembly and the pulling assembly to enable the mounting seat 103 to be quickly installed and disassembled with 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 installation of the mounting seat 103 and the base 101 is completed, the multiple groups of mines to be dropped are stored inside the two groups of storage barrels 601, and during the mine-laying process, the number of mines inside the two groups of storage barrels 601 is made the same. By setting the number of mines inside the two groups of storage barrels 601 to be the same, the center of gravity of the drone does not shift during the mine-laying flight, which facilitates the stable flight mine-laying operation of the mine-laying drone.

[0068] The drone is driven by the multiple rotors 102 on the base 101 to fly to the 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 of 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 state of the first square baffle 702 is that 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, completing the mine laying operation. The second square baffle 703 is extended 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 is extended 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 single mine placement operation;

[0069] During the mine laying and feeding process, since the gravity block 1001 and the uppermost mine inside the storage barrel 601 are kept in contact with each other, the gravity block 1001 moves downward synchronously with the mine being thrown outward during the mine laying process. When the storage barrel 601 on one side is used to throw mines, the number of mines inside the two groups of storage barrels 601 is different. At this time, there is a height difference between the gravity blocks 1001 inside the two groups of storage barrels 601. Due to the effect of the height difference and the connection effect 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 toward the storage barrel 601 on the side with fewer mines, and the square counterweight box 1006 tilts toward the storage barrel 601 on the mine throwing side (see FIG. 1 ). Figure 11 state), which is equivalent to moving the center of gravity of the liquid in the square counterweight box 1006 to that side. Due to the fluidity of the liquid, it can be redistributed in the square counterweight box 1006, increasing the weight of that side. According to the principle of lever, when the lever arm remains unchanged, increasing the force on that side can increase the moment of force on the center of gravity of that side, thereby effectively reducing the degree of deviation of the overall center of gravity of the drone caused by the mine feeding in the single-sided storage barrel 601, so that the center of gravity of the drone remains in a relatively stable position, maintaining the stability of the flight attitude, and subsequent During the mine laying and feeding process, another set of storage barrels 601 is used to perform a single mine feeding operation, so that the number of mines in the two sets of storage barrels 601 is the same. At this time, there is no height difference between the two sets of gravity blocks 1001. Through the connection function of the connecting rod 1003, the connecting plate 1004, the vertical plate 1005, the mounting plate 1008 and the mounting frame 1007 and the reset function of the sliding assembly on the two sets of mounting plates 1008 and the mounting frame 1007, the square counterweight box 1006 is reset and rotated to a horizontal position (see Figure 9 and Figure 10 state), keeping the center of gravity of the entire UAV from shifting, facilitating stable flight and mine-laying operations of the mine-laying UAV.
