Description

Technical Field

[0001] The present invention relates to the technical field of police drones, and specifically to a police drone equipped with a long-distance explosive destroyer. Background Art

[0002] A police drone equipped with a long-distance explosive destroyer is an unmanned flight platform that destroys or renders explosives ineffective at a safe distance through non-contact technologies (such as high-pressure water cannons, robotic arms, laser cutting, or remote detonation devices). Its core function is to replace traditional manual bomb disposal, reduce the risk of casualties, and improve the efficiency of emergency response. Currently, when disposing of explosives, most use high-pressure water cannon drones to destroy explosives. However, at the moment of using the high-pressure water cannon, the high-pressure water cannon is prone to generating a recoil force on the drone. The generated recoil force will cause the flight angle to deviate, affecting the position where the water cannon sprays the explosives, and thus affecting the working effect of destroying the explosives. Summary of the Invention

[0003] The purpose of the present invention is to provide a police drone equipped with a long-distance explosive destroyer. When the water level inside the balance component water tank drops, the floating plate follows the water level and descends. The descent of the floating plate drives the push block to descend, and the push block's descent squeezes the counterweight block to move in the direction opposite to the orientation of the water cannon, enabling the counterweight block to balance the recoil force generated by the water cannon, preventing the recoil force generated at the moment when the water cannon sprays water from causing the drone to deviate or displace, resulting in the drone deviating or displacing and the flight angle deviating, which affects the position where the water cannon sprays the explosives, and thus affects the working effect of destroying the explosives.

[0004] To achieve the above objective, the present invention provides the following technical solution: A police drone equipped with a long-distance explosive destroyer, including a drone, a destruction component is installed on the drone. The destruction component includes a water tank, a floating plate is installed inside the water tank, and a push block is installed at the lower end of the floating plate; A balance component is installed at the lower end of the drone. The balance component includes an outer frame, a counterweight block is installed inside the outer frame, the counterweight block is slidably connected to the push block, a first spring is connected to one side of the counterweight block, second racks are provided around the counterweight block, a first rack is connected to one side of the second racks, and a gear is meshed between the first rack and the second racks. Four groups of racks are installed on the outer frame; A clamping assembly is installed at the lower end of the balance assembly. The clamping assembly includes clamping arms, a telescopic plate is installed on the clamping arms, two groups of push rods are installed inside the telescopic plate, a magnet block is installed on the telescopic plate, a slider is magnetically connected to the magnet block, first racks are arranged around the slider, and the slider is movably installed inside the outer frame. A suction cup is installed inside the slider, a piston is installed inside the suction cup, an elastic rope is connected to the piston, and one side of the elastic rope is connected to a counterweight.

[0005] Preferably, a water cannon is installed on one side of the water tank, a pressure rod is connected to the lower end of the floating plate, one side of the pressure rod extends through the water tank and is installed, and one side of the pressure rod is connected to a push block.

[0006] Preferably, a cross-shaped groove is provided on the outer frame, four groups of gears are provided on the cross-shaped groove, the four groups of gears are installed on the cross groove through connecting rods, and the first rack is movably connected to the second rack through the gears.

[0007] Preferably, four groups of second springs are connected to the cross groove of the outer frame, and the other sides of the four groups of second springs are all connected to the first rack.

[0008] Preferably, a first groove is provided on the outer frame, one of the second racks moves on the first groove, a second groove is provided on the outer frame, and the rack moves on the second groove.

[0009] Preferably, a strong magnet is provided at the lower end of the slider, and the slider is magnetically connected to the magnet block through the strong magnet.

[0010] Preferably, both sides of the two push rods extend through the magnet block, and the push rods are connected to the suction cup.

[0011] Preferably, the clamping arm is provided with a cylinder, and clamping jaws are provided on both sides of the cylinder.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. When the water level inside the water tank drops, the floating plate follows the water level drop. The floating plate drop drives the push block to drop, and the push block drop squeezes the counterweight to move, so that the moving direction of the counterweight is opposite to the firing direction of the water cannon. The counterweight moves to one side of the drone, increasing the gravity on one side of the drone, thereby offsetting the recoil force generated by the water cannon, preventing the recoil force generated during the spraying of the water cannon from shifting or displacing the drone, resulting in an offset of the flight angle and affecting the spraying position of the water cannon on the explosive, and further affecting the working effect of destroying the explosive. 2. In the present invention, when the center of gravity of the explosive deviates, the explosive drives the clamping arm to move on the outer frame. The clamping arm presses the first rack, and the first rack drives the second rack to move in the opposite direction through a gear. The second rack drives the counterweight to move in the direction opposite to the deviation of the center of gravity of the explosive, so that the counterweight can adjust and balance the center of gravity of the unmanned aerial vehicle (UAV), preventing the UAV from being directly interfered with by the deviation of the center of gravity of the explosive, resulting in abnormal conditions such as attitude imbalance and course deviation of the airframe, thereby affecting its mission execution efficiency and accuracy. In severe cases, it may even trigger the out-of-control crash of the UAV, causing equipment damage and mission interruption, and may pose a secondary safety threat to the surrounding personnel and environment. 3. While the counterweight is moving, the elastic rope is pulled, causing the elastic rope to pull the piston to move upward inside the suction cup, exhausting the air inside the suction cup, and assisting in fixedly connecting the clamping arm, preventing the connection structure strength between the clamping arm and the UAV body from being insufficient, which may loosen and fall off due to vibrations, air flow disturbances or sudden impacts during transportation, such as mechanical failures and collisions with obstacles, resulting in the high-altitude fall of the explosive and causing a secondary explosion. 4. At the moment when the UAV lifts the explosive off the ground and is about to fly, when the weight of the explosive exceeds the self-gravity of the counterweight and the counterweight fails to adjust the balance of the UAV, since the self-gravity of the counterweight is equal to the magnetic attraction of the magnet block, when the weight of the explosive exceeds the self-gravity of the counterweight, the magnet block separates from the slider, causing the explosive to detach from the UAV, preventing the UAV from being affected when the explosive is too heavy and the center of gravity deviates excessively at the moment when it is about to fly after lifting the explosive off the ground. Because it is close to the ground, it may cause the rotary wing to contact the ground, damaging the wing and thus affecting the use of the UAV. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0015] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0016] Refer to Figures 1 to 2 As shown, the present invention provides a police unmanned aerial vehicle equipped with a long-distance explosive destroyer, including an unmanned aerial vehicle 1. The police remotely control the unmanned aerial vehicle 1 to destroy explosives. A destruction component 2 is installed on the unmanned aerial vehicle 1. The destruction component 2 is used to remotely destroy explosives to prevent the explosives from exploding. The destruction component 2 includes a water tank 201. The water tank 201 is used to store water source, which is discharged through a water cannon 202 and sprayed onto the explosives from a long distance to destroy the explosives. A floating board 203 is installed inside the water tank 201. When the water source in the water tank is delivered to the water cannon 202, the water level inside the water tank 201 drops, and the floating board 203 follows the water level and drops. A push block 205 is installed at the lower end of the floating board 203. The drop of the floating board 203 drives the push block 205 to drop and transmit power; Refer to Figures 2 to 4As shown, a balance component 3 is installed at the lower end of the drone 1. The balance component 3 is used to balance the center of gravity of the drone 1, prevent the center of gravity of the drone 1 from deviating, and affect the flight of the drone 1. The balance component 3 includes an outer frame 301. The outer frame 301 is used to protect the internal device. A counterweight 302 is installed inside the outer frame 301. The counterweight 302 slides inside the outer frame 301 to adjust the center of gravity of the drone 1. The counterweight 302 is slidably connected to the push block 205. One side of the counterweight 302 is connected to a first spring 303. The first spring 303 is used to drive the counterweight 302 to move and reset inside the outer frame 301 when it rebounds after elastic deformation. Second racks 307 are provided around the counterweight 302. The second racks 307 drive the counterweight 302 to move. One side of the second rack 307 is connected to a first rack 304. A gear 306 meshes between the first rack 304 and the second rack 307. The first rack 304 drives the second rack 307 to move in the opposite direction through the gear 306. Four sets of rulers 308 are installed on the outer frame 301. The rulers 308 are used to measure the weight of the explosive; When the police remotely control the drone 1 to destroy the explosive, the water cannon 202 draws water from the water tank 201 and sprays it onto the explosive from a distance to destroy the explosive. The water level inside the water tank 201 drops, and the floating plate 203 drops with the water level. The drop of the floating plate 203 drives the push block 205 to drop. The push block 205 drops and squeezes the counterweight 302 to move, so that the moving direction of the counterweight 302 is opposite to the firing direction of the water cannon 202. The counterweight 302 moves to one side of the drone 1, increasing the gravity on one side of the drone 1, thereby offsetting the recoil force generated by the water cannon 202, preventing the recoil force generated by the water cannon 202 at the moment of spraying water from offsetting or displacing the drone 1, resulting in an offset of the flight angle of the drone 1 and affecting the spraying position of the water cannon 202 on the explosive, and further affecting the working effect of destroying the explosive. The first spring 303 moves with the counterweight 302, the first spring 303 undergoes elastic deformation and stretches, and then the first spring 303 rebounds to drive the counterweight 302 back to the initial position; Refer to Figures 5 to 7As shown, a clamping assembly 4 is installed at the lower end of the balancing assembly 3. The clamping assembly 4 is used to clamp the destroyed explosives and is transported to a designated safe location by the drone 1. The clamping assembly 4 includes clamping arms 401 which clamp the explosives. A telescopic plate 402 is installed on the clamping arms 401. The telescopic plate 402 is flexible and can be bent into an arc. Two groups of push rods 403 are installed inside the telescopic plate 402. If the explosive is too heavy and the center of gravity deviates, it will drive the telescopic plate 402 to produce an arc bend. There is a flat surface on one side in the middle of the telescopic plate 402. When an arc bend occurs, the flat surface pushes out the two groups of push rods 403 for power transmission. A magnet block 404 is installed on the telescopic plate 402. The magnet block 404 is used to drive the telescopic plate 402 for connection. A slider 405 is magnetically connected to the magnet block 404. The magnet block 404 and the slider 405 are connected to the clamping arm 401 through the telescopic plate 402. First racks 304 are arranged around the slider 405. The slider 405 drives the first racks 304 to move, and the slider 405 is movably installed inside the outer frame 301. When the explosive is too heavy and the center of gravity deviates, the explosive drives the clamping arm 401 to move on the outer frame 301. The clamping arm 401 presses the first rack 304. The first rack 304 drives the second rack 307 to move in the opposite direction through the gear 306. The second rack 307 drives the counterweight 302 to move in the direction opposite to the deviation of the center of gravity of the explosive, so that the counterweight 302 can adjust the center of gravity of the drone 1 to prevent the drone 1 from deviating or displacing due to the deviation of the center of gravity of the explosive, which will directly interfere with the flight stability of the drone 1, resulting in abnormal conditions such as attitude imbalance and course deviation of the airframe, thereby affecting its mission execution efficiency and accuracy. In severe cases, it may even trigger the drone 1 to lose control and crash, causing equipment damage and mission interruption, and may pose a secondary safety threat to the surrounding personnel and environment; A suction cup 406 is installed inside the slider 405. The suction cup 406 is used to assist in fixing the clamping arm 401 by adsorbing the magnet block 404. A piston 407 is installed inside the suction cup 406. The piston 407 moves inside the suction cup 406 to pump out the air inside the suction cup 406. An elastic rope 408 is installed and connected to the piston 407. One side of the elastic rope 408 is connected to the counterweight 302. When the counterweight 302 moves, it pulls the elastic rope 408, causing the elastic rope 408 to pull the piston 407 to move upward inside the suction cup 406, pumping out the air inside the suction cup 406 to assist in fixedly connecting the clamping arm 401; When the clamping arm 401 clamps the destroyed explosive, if the explosive is too heavy and its center of gravity deviates, the explosive drives the clamping arm 401 to move on the outer frame 301. The clamping arm 401 squeezes the first rack 304, and the first rack 304 drives the second rack 307 to move in the opposite direction through the gear 306. The second rack 307 drives the counterweight 302 to move in the direction opposite to the deviation of the center of gravity of the explosive, so that the counterweight 302 can adjust the balance of the center of gravity of the drone 1, preventing the drone 1 from deviating or displacing due to the deviation of the center of gravity of the explosive. The deviation of the center of gravity will directly interfere with the flight stability of the drone 1, resulting in abnormal conditions such as attitude imbalance and course deviation of the airframe, thereby affecting its mission execution efficiency and accuracy. In severe cases, it may even trigger the out-of-control crash of the drone 1, causing equipment damage and mission interruption, and may pose a secondary safety threat to surrounding personnel and the environment; While the counterweight 302 moves, it pulls the elastic rope 408, causing the elastic rope 408 to pull the piston 407 to move upward inside the suction cup 406, exhausting the air inside the suction cup 406, and assisting in the fixed connection of the clamping arm 401, preventing the connection structure strength between the clamping arm 401 and the main body of the drone 1 from being insufficient, which may loosen and fall off due to vibrations, air flow disturbances or sudden impacts during transportation, such as mechanical failures and collisions with obstacles, resulting in a secondary explosion when the explosive falls from a high altitude; When the drone 1 is about to fly immediately after lifting the explosive off the ground, if the explosive exceeds the self-gravity of the counterweight 302 and the counterweight 302 fails to adjust the balance of the drone 1, the counterweight 302 drives the telescopic plate 402 to produce an arc bend through the clamping arm 401. There is a flat surface on one side of the middle of the telescopic plate 402. When an arc bend occurs, the flat surface ejects two groups of push rods 403. The two groups of push rods 403 push the suction cup 406, causing the suction cup 406 to deflate and no longer adsorb and fix through the clamping arm 401 by the magnet block 404. Then, because the self-gravity of the counterweight 302 is equal to the magnetic suction force of the magnet block 404, when the explosive exceeds the self-gravity of the counterweight 302, the magnet block 404 separates from the slider 405, causing the explosive to detach from the drone 1, preventing the drone 1 from being about to fly immediately after lifting the explosive off the ground. If the explosive is too heavy and the center of gravity deviates excessively, because it is close to the ground, it may cause the rotary wing to contact the ground, damaging the wing and thus affecting the use of the drone 1; While the clamping arm 401 moves, it will also squeeze the scale bar 308. By moving the scale bar 308 according to the value marked on it on the outer frame 301, the weight of the explosive can be judged, which is convenient for the police officers to start the drone 1 with a suitable configuration and transport the explosive to the designated safe location.

[0017] In an alternative embodiment, a water cannon 202 is installed on one side of the water tank 201. A pressure rod 204 is connected to the lower end of the floating plate 203. One side of the pressure rod 204 extends through the water tank 201 for installation, and one side of the pressure rod 204 is connected to the push block 205. The water cannon 202 draws water from the inside of the water tank 201 and sprays it onto the explosive from a long distance to destroy the explosive. The water level inside the water tank 201 drops, and the floating plate 203 drops along with the water level. The drop of the floating plate 203 drives the push block 205 to drop through the pressure rod 204. The drop of the push block 205 squeezes the counterweight 302 to move, so that the moving direction of the counterweight 302 is opposite to the direction of the water cannon 202 firing. The counterweight 302 moves to one side of the drone 1, increasing the gravity on one side of the drone 1, thereby offsetting the recoil force generated by the water cannon 202, preventing the recoil force generated when the water cannon 202 sprays water from deflecting or displacing the drone 1, resulting in the deflection or displacement of the drone 1 and the deviation of the flight angle, affecting the position where the water cannon 202 sprays the explosive, and further affecting the working effect of destroying the explosive.

[0018] In an alternative embodiment, a cross-shaped groove is provided on the outer frame 301. Four sets of gears 306 are provided on the cross-shaped groove. The four sets of gears 306 are installed on the cross groove through connecting rods. The first rack 304 is movably connected to the second rack 307 through the gears 306. The explosive drives the clamping arm 401 to move in the cross-shaped groove on the outer frame 301. The clamping arm 401 squeezes the first rack 304. The first rack 304 drives the second rack 307 to move in the opposite direction through the gears 306. The second rack 307 drives the counterweight 302 to move in the direction opposite to the deviation of the center of gravity of the explosive, so that the counterweight 302 can adjust the balance of the center of gravity of the drone 1, preventing the drone 1 from deviating or displacing due to the deviation of the center of gravity of the explosive. The deviation of the center of gravity will directly interfere with the flight stability of the drone, resulting in abnormal conditions such as attitude imbalance and heading deviation of the airframe, thereby affecting its task execution efficiency and accuracy. In severe cases, it may even trigger the out-of-control crash of the drone 1, causing equipment damage and mission interruption, and may pose a secondary safety threat to the surrounding personnel and environment.

[0019] In an alternative embodiment, four sets of second springs 305 are connected to the cross groove of the outer frame 301. The other sides of the four sets of second springs 305 are all connected to the first rack 304. The second spring 305 is used to drive the first rack 304 to return to its initial position after the spring of the second spring 305 finishes working.

[0020] In an alternative embodiment, a first groove is provided on the outer frame 301, and one set of second racks 307 moves on the first groove. When the push block 205 descends to squeeze the counterweight 302 towards the direction opposite to the direction of the water cannon 202, the counterweight 302 drives the second rack 307 to move on the first groove, so that the second rack 307 does not affect the movement of the counterweight 302. A second groove is provided on the outer frame 301, and the scale bar 308 moves on the third groove. The value marked on the scale bar 308 moves to the outer frame 301 through the third groove to determine the weight of the explosive, facilitating the police officers to activate the drone 1 with a suitable configuration and transport the explosive to a designated safe location.

[0021] In an alternative embodiment, a strong magnet is provided at the lower end of the slider 405. The slider 405 is magnetically connected to the magnet block 404 through the strong magnet, and the magnet block 404 is magnetically connected through the strong magnet on the slider 405, and is connected to the clamping arm 401 through the telescopic plate 402.

[0022] In an alternative embodiment, both sets of push rods 403 extend through the magnet block 404 on one side, and the push rods 403 are connected to the suction cups 406. The counterweight 302 drives the telescopic plate 402 to generate an arc bend through the clamping arm 401. There is a flat surface on one side in the middle of the telescopic plate 402. When an arc bend occurs, the flat surface pushes out the two sets of push rods 403, and the two sets of push rods 403 push the suction cups 406, causing the suction cups 406 to deflate and no longer adsorb and fix through the magnet block 404 through the clamping arm 401.

[0023] In an alternative embodiment, the clamping arm 401 is provided with a cylinder, and clamping claws are provided on both sides of the cylinder. The cylinder drives the clamping claws to clamp the explosive through telescopic movement.

[0024] Working principle: When the police remotely control the drone 1 to destroy the explosive, the water cannon 202 draws water from the inside of the water tank 201 and sprays it onto the explosive from a distance to destroy the explosive. The water level inside the water tank 201 drops, and the floating plate 203 drops along with the water level. The dropping of the floating plate 203 drives the push block 205 to drop, and the push block 205 drops to squeeze the counterweight 302 to move, so that the moving direction of the counterweight 302 is opposite to the direction of the water cannon 202. The counterweight 302 moves to one side of the drone 1, increasing the gravity on one side of the drone 1, thereby offsetting the recoil force generated by the water cannon 202, preventing the recoil force generated at the moment when the water cannon 202 sprays water from offsetting or displacing the drone 1, resulting in the drone 1 being offset or displaced and the flight angle being offset, affecting the position where the water cannon 202 sprays the explosive, and further affecting the working effect of destroying the explosive. The first spring 303 moves along with the counterweight 302, the first spring 303 undergoes elastic deformation and stretches, and then the first spring 303 rebounds to drive the counterweight 302 back to the initial position; When the clamping arm 401 clamps the destroyed explosive, if the explosive is too heavy and the center of gravity deviates, the explosive drives the clamping arm 401 to move on the outer frame 301. The clamping arm 401 squeezes the first rack 304, and the first rack 304 drives the second rack 307 to move in the opposite direction through the gear 306. The second rack 307 drives the counterweight 302 to move in the direction opposite to the deviation of the center of gravity of the explosive, so that the counterweight 302 can adjust the balance of the center of gravity of the UAV 1, preventing the UAV 1 from deviating or displacing due to the deviation of the center of gravity of the explosive. The deviation of the center of gravity will directly interfere with the flight stability of the UAV 1, resulting in abnormal conditions such as attitude imbalance and course deviation of the airframe, thereby affecting its mission execution efficiency and accuracy. In severe cases, it may even trigger the out-of-control crash of the UAV 1, causing equipment damage and mission interruption, and may pose a secondary safety threat to the surrounding personnel and environment; While the counterweight 302 moves, it pulls the elastic rope 408, causing the elastic rope 408 to pull the piston 407 to move upward inside the suction cup 406, exhausting the air inside the suction cup 406, and assisting in the fixed connection of the clamping arm 401, preventing the connection structure strength between the clamping arm 401 and the UAV 1 main body from being insufficient. It may become loose and fall off due to vibrations, air flow disturbances or sudden impacts during transportation, such as mechanical failures and collisions with obstacles, resulting in a secondary explosion when the explosive falls from a high altitude; When the UAV 1 is about to fly immediately after lifting the explosive off the ground, if the explosive exceeds the self-gravity of the counterweight 302 and the counterweight 302 fails to adjust the balance of the UAV 1, the counterweight 302 drives the telescopic plate 402 to produce an arc bend through the clamping arm 401. There is a flat surface on one side of the middle of the telescopic plate 402. When an arc bend occurs, the flat surface ejects two groups of push rods 403. The two groups of push rods 403 push the suction cup 406, causing the suction cup 406 to deflate and no longer adsorb and fix through the clamping arm 401 by the magnet block 404. Then, because the self-gravity of the counterweight 302 is equal to the magnetic suction of the magnet block 404, when the explosive exceeds the self-gravity of the counterweight 302, the magnet block 404 separates from the slider 405, causing the explosive to detach from the UAV 1, preventing the UAV 1 from being about to fly immediately after lifting the explosive off the ground. If the explosive is too heavy and the center of gravity deviates too much, because it is close to the ground, it may cause the rotary wing to contact the ground, damaging the wing, and thus affecting the use of the UAV 1; While the clamping arm 401 moves, it will also squeeze the scale bar 308, and judge the weight of the explosive according to how much the scale bar 308 marked on it moves to the outer frame 301, which is convenient for the police officers to start the UAV 1 with a suitable configuration and transport the explosive to the designated safe location.

[0025] Although embodiments of the present invention have been shown and described, those of ordinary skill in the art will appreciate that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
