Description

Technical Field

[0001] The present invention relates to the technical field of anti-UAV, and in particular to a net-catching power mechanism for anti-UAV. Background Art

[0002] With the rapid development of drone technology, its widespread application in military, civilian, and commercial fields has brought many conveniences, but it has also given rise to new security threats. Cases of drones being abused for illegal surveillance, smuggling, terrorist attacks and other activities are common. Especially in the military field, small drones have become a major threat on the modern battlefield due to their low cost, high maneuverability and stealth. In addition, illegal intrusions of civilian drones into sensitive areas such as airports, nuclear power plants, and government agencies have also occurred frequently, seriously threatening public safety and national interests. Therefore, the research and application of anti-drone technology has become an important issue that needs to be urgently addressed worldwide.

[0003] The development of anti-drone technology mainly revolves around the four core links of detection, identification, interference and destruction. In terms of detection, radar, optoelectronics, acoustics and radio spectrum monitoring are widely used in early warning of drones. Among them, radar technology has become mainstream due to its all-weather and long-range detection capabilities, but when facing small drones, its detection accuracy and anti-interference capabilities still need to be further improved. Optoelectronic technology uses infrared and visible light imaging to accurately identify drones, but is limited by weather and lighting conditions. Acoustic detection uses the unique noise characteristics of drones for identification, but its effective range is short and is suitable for close-range defense. Radio spectrum monitoring detects by capturing the communication signals of drones, but it is difficult to detect when facing interference. When it comes to drones equipped with dense communication and frequency hopping technologies, their effectiveness is greatly reduced. In the identification link, the introduction of artificial intelligence and machine learning technologies has significantly improved the classification and threat assessment capabilities of drone targets, but the real-time and accuracy of the algorithms still need to be optimized. Interference technology mainly destroys the navigation and control systems of drones through electromagnetic pulses, GPS deception and communication interference, forcing them to land or return. However, as the anti-interference capabilities of drones are enhanced, the effectiveness of traditional interference methods has gradually weakened. Destruction technologies include laser weapons, microwave weapons and traditional firepower strikes, but when facing small drones, the use of destruction technology will incur a large cost. The use of netting technology can often achieve the purpose of countering small drones simply and efficiently. Summary of the Invention

[0004] In response to the problems in the prior art, the present invention provides a net-catching power mechanism for countering UAVs.

[0005] The technical solution adopted by the present invention to solve the technical problem is: a net-catching power mechanism for anti-UAV, comprising a UAV, a launching tube, a launching head and a connecting rope;

DETAILED DESCRIPTION

[0030] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0031] The present invention will be further described below with reference to the accompanying drawings.

[0032] Example 1

[0033] like Figure 1-3 As shown, a net-catching power mechanism for anti-UAV of the present invention includes a UAV, a launching tube 20, a launching head 30 and a connecting rope 31;

[0034] A launching tube 20 is fixed at the lower end of the drone, and a launching head 30 is connected to the lower end of the launching tube 20 by pushing. The lower end of the launching head 30 is connected to a connecting rope 31. There are four launching tubes 20, launching heads 30, and connecting ropes 31, which are installed on four drones. The four connecting ropes 31 connect the four corners of the capture net, and push the capture net to capture the drone to be captured below. First, the hydraulic motor 11 is started to apply the required pressure to the liquid. At this time, the liquid pressure control is controlled by the preset value of the relief valve 13. Then, the three-position four-way solenoid reversing valve 12 and the limit switch 21 are started at the same time. When the three-position four-way solenoid reversing valve 12 is reversed to the corresponding position, the liquid with huge pressure flows into the double-acting hydraulic cylinder 14, thereby pushing the piston inside it to move downward rapidly to generate thrust, thereby pushing the launching head 30 to move. After the launching head 30 is launched, the three-position four-way solenoid reversing valve 12 is reversed, and the liquid direction is reversed, thereby pushing the piston in the double-acting hydraulic cylinder 14 to return to its original position for subsequent use.

[0035] The side end of the launch head 30 is limited by the limit switch 21, and the limit switch 21 supports the launch head 30. The limit switch 21 is installed on the launch tube 20. A double-acting hydraulic cylinder 14 is provided in the launch tube 20. The double-acting hydraulic cylinder 14 reciprocates and retracts in the launch tube 20, and the double-acting hydraulic cylinder 14 contacts the launch head 30 to push the launch head 30. The double-acting hydraulic cylinder 14 is connected to the three-position four-way electromagnetic reversing valve 12 through the oil circuit, and the three-position four-way electromagnetic reversing valve 12 is connected to the hydraulic motor 11 and the overflow valve 13. The hydraulic motor 11 is also connected to the oil tank 10.

[0036] The side end of the limit switch 21 is fixedly connected with a rack 22, and the rack 22 is slidably connected to the ram 27, and the rack 22 is fixedly connected with a slide rail 23, and the slide rail 23 is movably connected with a crank slider 24. The lower end of the ram 27 is fixedly connected with a base 28, and the crank slider 24 is fixedly connected with a gear 25. A small motor 26 is installed on the gear 25, and the small motor 26 is also supported by the base 28. Start the small motor 26. Set the small motor 26 so that when it starts, the rotor first rotates half a circle, and then rotates half a circle after an interval of 1s. The small motor After 26 is started, it drives the gear 25 to move, and the gear 25 is connected to the crank slider 24 for rotational motion. The crank slider 24 slides on the slide rail 23 so that the slide rail 23 is fixed with the rack 24 and performs reciprocating translation motion on the ram 27. The rack 24 is fixed with the limit switch 21 so that the limit switch 21 performs reciprocating motion. When the rotor rotates the first half circle, the limit switch 21 moves backward to release the restriction on the launch head 30. After an interval of one second, the launch head has been launched, and the rotor rotates the second half circle to restore the limit switch 21 to its original position for subsequent use.

[0037] The small motor 26 drives the crank slider 24 to rotate through the gear 25. The crank slider 24 slides on the slide rail 23, driving the crank slider 24, the rack 22, and the limit switch 21 to reciprocate on the slide 27.

[0038] The working principle is as follows: when in use, it relies on the coordinated work of multiple drones, and four high-speed drones are used at the same time. Each drone is equipped with a net-catching launch device, and the ends of the four launch devices are connected to the net rope. These four net ropes are connected to the capture net at the same time, so that the capture net is deployed in the middle area surrounded by the four drones, which can form a large net-catching area. When the target drone is found, the four drones are driven to fly above the target, and the launch devices on the four drones are started at the same time, so that the launch heads are quickly launched, so that the capture net quickly catches the target drone under the drive of the four launch heads and their connecting ropes. The launch device on each drone adopts a hydraulic transmission mechanism, which includes:

[0039] Fuel tank 10, hydraulic power output device hydraulic motor 11, three-position four-way solenoid reversing valve 12, relief valve 13, double-acting hydraulic cylinder 14, launching tube 20, limit switch 21, launching head 30, connecting rope 31. On the one hand, the use of double-acting hydraulic cylinder 14 can make the piston therein move in both directions, so that the piston automatically retracts after pushing the launching head 30 to launch for subsequent reuse. The oil circuits at both ends of the double-acting hydraulic cylinder 14 are connected to the three-position four-way solenoid reversing valve 12 to realize the conversion of the oil circuit flow direction. The hydraulic motor 11 is used to provide hydraulic power and output the hydraulic power of the oil circuit to the three-position four-way solenoid reversing valve 12. A relief valve 13 is connected between the oil circuits to maintain the system pressure within the set range, protect the hydraulic components from damage, and ensure stable operation of the system. The launch device startup process is as follows: first, the hydraulic motor 11 is started to provide power, and then the three-position four-way electromagnetic reversing valve 12 and the limit switch 21 are controlled to move simultaneously, thereby pushing the piston in the double-acting hydraulic cylinder 14 to move. The piston generates a huge linear impulse that is transmitted to the launch head 30. The launch head 30 launches directly downward, driving the connecting rope. As the launch heads 30 of the four drones are launched simultaneously, the huge capture net will move directly downward at high speed, thereby capturing the target drone.

[0040] The limit switch 21 includes the following components: a rack 22, a slide rail 23, a crank slider 24, a gear 25, a small motor 26, a ram 27, and a base 28. On the one hand, when the small motor 26 is started, it drives the gear 25 to move, and the gear 25 is connected to the crank slider 24 for rotational motion. The crank slider 24 slides on the slide rail 23 so that the slide rail 23 is fixed to the rack 24 and reciprocating translational motion is performed on the ram 27. The rack 24 is fixed to the limit switch 21 so that the limit switch 21 reciprocates, thereby realizing the limiting effect of the limit switch 21 on the launch head 30. The small motor 26 is set so that the rotor rotates half a circle when it starts, and then rotates half a circle after an interval of 1s. At the same time, the small motor 26 and the three-position four-way electromagnetic reversing valve 12 are started, then the limit switch is opened, and the launch head is pushed out by the thrust of the piston. After 1s, the limit switch returns to its original position, completing the entire launch process and completing the work.

[0041] Example 2

[0042] On the basis of Example 1, Figure 4-7 As shown, an independent net-casting structure 40 is installed at the lower part of the UAV wing.

The upper end of the fixed block 42 is fixed to the wing. The rear end of the fixed block 42 is fixedly connected to a hinge seat 43. The center of the hinge seat 43 is fixedly connected to a hinge connecting rod 50. The side end of the hinge connecting rod 50 is hinged with a spring telescopic rod 49. The lower end of the spring telescopic rod 49 is hinged with a docking hinge block 47. The lower end of the docking hinge block 47 is fixedly connected to a second launch tube 45. The second launch tube 45 has the same structure as the launch tube 20. The central upper end of the second launch tube 45 is fixedly connected to a drive rod 44. One side of the drive rod 44 is rotatably connected to the bearing ring sleeve 48. The side of the drive rod 44 away from the bearing ring sleeve 48 is connected to the micro motor 41. An independent net-casting structure 40 is set at the lower end of the wing. The independent net-casting structure 40 has an angle adjustment function and can cast independently. The net structure 40 operates independently and does not affect the operation of the launch tube 20, the launch head 30, and the connecting rope 31. At this time, the fixed block 42 is fixed to the lower end of the wing. When the angle adjustment is required, the micro motor 41 works to drive the drive rod 44 to rotate, and the micro motor 41 controls the rotation angle of the drive rod 44 to be 70 degrees clockwise. The other side of the drive rod 44 is connected through the bearing ring sleeve 48 to rotate the drive rod 44 so that the drive rod 44 rotates on the bearing ring sleeve 48. At the same time, when the second launch tube 45 moves, the docking hinge block 47 follows the movement, and a spring telescopic rod 49 is hingedly provided on the docking hinge block 47. A hinged connecting rod 50 is hingedly provided on the spring telescopic rod 49. When the second launch tube 45 moves, the spring telescopic rod 49 can be telescopically coordinated to improve the operating stability of the second launch tube 45.

[0044] The micro motor 41 changes the position of the second launch tube 45 through the driving rod 44. The lower end of the second launch tube 45 is triggered to have an independent net-casting component 46.

When pushed, the push rod 52 is driven to move, and the lower end of the push rod 52 is fixedly connected to a shaft sleeve 55, and a net body 53 is sleeved on the shaft sleeve 55 and the push rod 52, and a counterweight block 54 is provided at the corner position of the net body 53. The second launch tube 45 has the same structure as the launch tube 20. The propellant in the ammunition seat 51 is triggered by the movement of the double-acting hydraulic cylinder 14, so that the push rod 52 can be pushed, driving the shaft sleeve 55 to move together. During movement, the net body 53 can be opened under the action of the gravity of the counterweight block 54, and come into contact and entangle with the propeller of the wing of the drone to be captured, thereby performing the capture task of the drone below.

[0045] The ammunition launcher 51 pushes the push rod 52 and the shaft sleeve 55 to move, so that the ammunition launcher 51 is separated from the push rod 52. At this time, the net 53 is opened under the weight of the counterweight 54, forming an open net structure, and the propeller of the drone to be captured is wrapped around.

[0046] When in use, an independent net-casting structure 40 is provided at the lower end of the wing. The independent net-casting structure 40 has an angle adjustment function, and the independent net-casting structure 40 operates independently without affecting the operation of the launch tube 20, the launch head 30, and the connecting rope 31. At this time, the fixed block 42 is fixed to the lower end of the wing. When the angle adjustment is required, the micro-motor 41 works to drive the drive rod 44 to rotate, and the micro-motor 41 controls the rotation angle of the drive rod 44 to rotate 70 degrees clockwise. The other side of the drive rod 44 is connected through the bearing ring 48 to rotate the drive rod 44, so that the drive rod 44 rotates on the bearing ring 48.

At this time, the sliding adjustment block 56 is fixed to the independent net-casting structure 40. The sliding adjustment block 56 can be slid and adjusted on the track frame 57, thereby adjusting the position of the independent net-casting structure 40. At this time, the stepper motor 59 controls the rotation of the screw rod 60, so that the sliding adjustment block 56 and the adjustment frame 58 slide and adjust on the track frame 57, driving the independent net-casting structure 40 to adjust the lateral position. After reaching the appropriate position, the angle of the independent net-casting structure 40 is adjusted to determine the direction and perform the drone's capture task. Through the adjustment of the lateral position, the position adjustment can be refined, thereby better ensuring the contact between the net body and the drone and performing the drone's capture work.
