Description

Technical Field

[0001] The present invention belongs to, but is not limited to, the technical field of interception nets, and particularly relates to a multi-point traction type interception net launching device. Background Art

[0002] Flexible capture refers to the capture of a target by means of devices such as a flexible net, a pocket, a flexible rope, etc. It does not need to consider a specific capture position and can adapt to the capture of targets with different shapes and sizes. In addition, flexible capture has the characteristics of non-lethality, a relatively wide acting area, a relatively long distance, etc. It can effectively control the situation in dealing with emergencies in a complex urban environment and avoid excessive harm at the same time. Among various different devices such as flexible nets, pockets, and flexible ropes, flexible nets are the most widely used and are widely applied in fields such as UAV capture, non-lethal weapons, space capture, and protective interception.

[0003] In view of the above analysis, the technical problems urgently to be solved in the existing technology are that the operation mode of the existing interception net launching device is complex and it is not convenient for repeated use. Summary of the Invention

[0004] Aiming at the problems existing in the prior art, the present invention provides a multi-point traction type interception net launching device, which drives the unfolded folded interception net by means of launching a traction mass block.

[0005] The present invention is realized as follows. A multi-point traction type interception net launching device includes a base, a power device, a launcher, and an interception net; the base can be adjusted and positioned at multiple angles and should withstand an impact force of at least not less than 15 KN. It is designed as a folding structure to reduce the packaging volume and facilitate transportation and storage; the power device uses compressed air as a power source, and high-pressure air is filled in the air storage chamber. When the switch is turned on, the energy of the high-pressure air is instantly released, and a huge aerodynamic force acts on the pressure-bearing area of the object, causing the object to accelerate from a stationary state and be projected. The main body of the power device is composed of a launch tube, an air chamber, a valve core assembly, a firing device, a trigger, a carbon fiber gas cylinder, a housing, etc. The launch tube, the carbon fiber gas cylinder, and the housing are distributed on both sides of the air chamber, and the firing device is arranged above the air chamber, and the trigger presses on the firing device; the launcher is in a horn shape, and four cylindrical storage bins connected to the launch tube are arranged at the edge.

[0006] Furthermore, the power device adopts a structure that uses the pressure difference of compressed air in the cavity to open the air plug. When the switch button is in the initial position, under the action of the return spring, the switch piston separates the large air chamber from the launch tube by the air plug, and the pressures of the large and small air plugs are atmospheric pressures; when in use, the large and small air chambers are simultaneously inflated, and the pressures are equal. The area of the piston in the small air chamber is larger than that in the large air chamber, and the pressure in the launch tube is still the atmospheric pressure. There is a huge pressure difference between the large air chamber and the launch tube, and the contact surface between the air plug and the launch tube is subjected to the acting force of the gas pressure on the air plug and the piston.

[0007] Furthermore, when the power device presses the launch switch, the air inlets of the large and small air chambers are closed, and the air inlet of the small air chamber communicates with the atmosphere, causing the pressure difference to increase rapidly. The piston end face area is larger than the air plug end face area. When the pressure difference between the two ends of the piston is greater than the air plug pressure, the piston and the air plug quickly move backward, and the high-pressure air in the large air chamber is instantly released into the launch tube, thereby driving the launched object to move.

[0008] Furthermore, the air chamber cover of the air chamber is connected to the front tube, and a gasket is provided inside the air chamber cover. One end of the cavity is inserted into the air chamber cover, and the cavity and the air chamber cover are sealed and connected; the other end of the cavity is connected to the air chamber body, and a valve core assembly is provided at the front end of the air chamber body. The valve core assembly consists of a hollow valve core rod, a valve core fixing block, a valve core, and a valve core cap; one end of the valve core rod is fixed to the main body of the launch device and communicates with the launch switch and the inflation valve through the gas passage on the air chamber body. The other end of the valve core rod is connected to the valve core through the valve core fixing block. The valve core cap is provided on the valve core and can move axially on the valve core. The cavity forms a closed space through the valve core assembly and the main body.

[0009] Furthermore, a carbon fiber gas cylinder and a housing are also provided at the tail of the main body of the launch device. The carbon fiber gas cylinder is connected to the inflation valve through a pipe thread, and the housing wraps the carbon fiber gas cylinder and is fixed to the air chamber. A pressure gauge is provided on the inflation valve, and the pressure of the gas in the air chamber is determined by observing the pressure gauge.

[0010] Furthermore, the carbon fiber high-pressure gas cylinder has a capacity of 2L and a pressure resistance of 30MPa. When using the gas cylinder to supply gas, it can be continuously launched more than 2 times after one inflation; the filled gas is compressed air, and the launch tube can match a 1.8kg throwing bomb to reach a range of 500m.

[0011] Furthermore, before launching, the four columnar mass blocks of the interception net are placed in the storage bin, and the interception net is folded and placed in the middle of the launcher. After launching, the mass blocks are pushed and obtain an initial velocity parallel to the axis of the storage bin. Since there is a certain angle between the axis of the 4-mass-block storage bin and the axis of the launch device, the mass blocks will move radially during flight, thereby pulling and unfolding the net body.

[0012] The present invention also provides a launching method for a multi-point traction type interception net, including the following steps:

[0013] a) Align the base of the launch device with the target direction and lock it;

[0014] b) Fill the air chamber of the device with compressed air until the designed working pressure;

[0015] c) Place the four columnar mass blocks into the corresponding storage bins respectively, fold the interception net and place it in the middle of the launcher, and tie the net corners to the mass blocks;

[0016] d) Trigger the launch switch, so that high-pressure air enters the launch tube through the valve core assembly and pushes the mass blocks to accelerate and shoot out along the axes of their respective storage bins;

[0017] e) During the flight of the mass blocks, the interception net is pulled out and forms an interception curtain.

[0018] Furthermore, a fixed angle is provided between the axes of the four storage bins and the overall axis of the launch device. When shooting out, the mass blocks move radially along their respective trajectories, so that the interception net forms a planar unfolded state in the air.

[0019] Furthermore, after step b), the air pressures of the large air chamber and the small air chamber are first adjusted to be equal, and then the air inlet passage is closed. After the launch is completed, the air chamber is inflated again through the inflation valve, so as to achieve multiple consecutive launches.

[0020] Combined with the above technical solutions and the solved technical problems, the advantages and positive effects of the technical solution to be protected by the present invention are as follows:

[0021] First, the launch method of the present invention is relatively simple. Only by adjusting different initial launch speeds and launch directions can the launch tasks for different interception nets be achieved, which is convenient for the design and repeated use of the launch device. Moreover, after the mass blocks are launched by traction, the interception net can be unfolded without additional control operations. The traction of the mass blocks uses the transmission of the tension between the rope segments, and pulls each node from the outside to the inside of the interception net along the rope segments to fly in the specified direction. By setting a special launch angle, the interception net can be unfolded outward while flying along the specified trajectory.

[0022] Second, the multi-point traction type interception net launch device of the present invention realizes the efficient, precise unfolding and long-distance projection of the interception net through an innovative compressed air power system and multi-angle traction design, and has broad application prospects in the fields of UAV countermeasures, public security riot prevention, space target capture and protection, etc. Its core technical advantages are reflected in: the modular folding base (bearing pressure ≥ 15KN) takes into account portability and stability, and the 30MPa carbon fiber gas cylinder power system supports more than 2 consecutive launches with a single inflation (the range reaches 500m / 1.8kg load), which significantly improves the use safety and unfolding reliability compared with traditional gunpowder or single-point traction devices. This device can be derived into interception equipment, police non-lethal weapons and civilian UAV control systems, and is expected to occupy a share in the anti-UAV equipment market (the global scale will exceed 3 billion US dollars in 2025). At the same time, through multiple business models such as pneumatic module patent licensing, customized models and civilian security protection suits, it is expected to create huge industrial chain value within three years after the technology transformation.

[0023] The present invention fills three technological gaps in the field of interception net launching devices at home and abroad: First, it pioneers a high-pressure pneumatic differential pressure drive system, realizing a green power solution for safe and repeatable launching, with performance indicators leading internationally; second, it breaks through the four-axis radial mass block traction technology, enabling the net body to deploy in a precise angle-regulated manner, thus solving the problem of incomplete deployment of traditional single-point traction; third, it develops a multi-angle adjustable base with both load-bearing capacity and rapid folding characteristics, achieving the ability to deploy immediately in complex environments.

[0024] The present invention overcomes three long-existing technological prejudices in the industry: First, it realizes a safer and more environmentally friendly power solution through an innovative high-pressure pneumatic differential pressure system; second, it significantly improves the deployment speed and reliability by adopting the four-axis radial mass block traction technology; third, it simultaneously achieves load-bearing capacity and rapid folding deployment characteristics through modular design. These innovations not only solve the pain points of the industry but also open up a new direction for the development of interception equipment. Brief Description of the Drawings

[0035] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below in conjunction with embodiments. It should be understood that the specific embodiments described herein are merely used to explain the present invention and are not intended to limit the present invention.

[0036] The multi-point traction interception net direct launching device is as Figure 1 , Figure 2 shown, and mainly includes a base 3, a power device 2, a launcher 1 and an interception net:

[0037] The base 3 (see Figure 3 ) can be adjusted and positioned at multiple angles, and the impact force it can withstand should be at least not less than 15 KN. It is designed as a folding structure to reduce the packaging volume and facilitate transportation and storage;

[0038] The power device 2 uses compressed air as the power source. High-pressure air is filled in the air storage chamber. When the switch is turned on, the energy of the high-pressure air is instantaneously released. The huge aerodynamic force acts on the pressure-receiving area of the object, causing the object to accelerate from a stationary state and be projected. We designed a structure that uses the pressure difference of the compressed air in the cavity to open the air plug, as Figure 4 shown. When the switch button is in the initial position, under the action of the return spring, the atmosphere chamber and the launch tube have been separated by the air plug, and the pressures of the large and small air plugs are the atmospheric pressure. When in use, the large and small air chambers are simultaneously inflated, and the pressures are equal. The area of the piston in the small air chamber is larger than that in the large air chamber. The pressure in the launch tube is still the atmospheric pressure, and there is a huge pressure difference between the atmosphere chamber and the launch tube. The contact surface between the air plug and the launch tube is subjected to the gas pressure acting on the air plug and the piston, pressing it tighter and having better sealing performance. When the launch switch is pressed, the air inlet channels of the large and small air chambers are closed, the air inlet of the small air chamber is communicated with the atmosphere, and the pressure difference increases rapidly. The area of the piston end face is larger than that of the air plug end face. When the pressure difference between the two end faces of the piston is greater than the pressure of the air plug, the piston and the air plug quickly retreat, and the high-pressure air in the atmosphere chamber is instantaneously released into the launch tube, thereby pushing the launched object to move.

[0039] The main body of the power device ( Figure 5 ) is composed of a launch tube, an air chamber, a valve core assembly, a firing device, a trigger, a carbon fiber gas cylinder, a housing, etc. The launch tube, the carbon fiber gas cylinder, and the housing are distributed on both sides of the air chamber, and the firing device is arranged above the air chamber, and the trigger presses on the firing device.

[0040] The air chamber cover of the air chamber is connected to the front tube. A gasket is provided inside the air chamber cover. One end of the cavity is inserted into the air chamber cover, and the cavity and the air chamber cover are sealed and connected; the other end of the cavity is connected to the air chamber body. A valve core assembly is provided at the front end of the air chamber body. The valve core assembly is composed of a hollow valve core rod, a valve core fixing block, a valve core and a valve core cap; one end of the valve core rod is fixed on the main body of the launching device and is communicated with the launching switch and the inflation valve through the gas passage on the air chamber body. The other end of the valve core rod is connected to the valve core through the valve core fixing block. The valve core cap is arranged on the valve core and can move axially on the valve core. The cavity forms a closed space through the valve core assembly and the main body.

[0041] At the tail of the main body of the launching device, there is also a carbon fiber gas cylinder and a housing. The carbon fiber gas cylinder is connected to the inflation valve through pipe threads. The housing wraps the carbon fiber gas cylinder and is fixed on the air chamber. A pressure gauge is provided on the inflation valve, and the pressure of the gas in the air chamber is determined by observing the pressure gauge.

[0042] The carbon fiber high-pressure gas cylinder (see Figure 6 ) has a capacity of 2L and a pressure resistance of 30MPa. When using the gas cylinder to supply gas, one inflation can ensure continuous launching more than 2 times; the filled gas is compressed air, which can ensure that the launch tube can match a 1.8kg throwing bomb to reach a range of 500m.

[0043] The launcher is as Figure 7 shown. The launcher is in a horn shape, and four cylindrical storage bins connected to the launch tube are arranged at the edge. Before launching, the four columnar mass blocks of the interception net are placed in the storage bins, and the interception net is folded and placed in the middle of the launcher. After launching, the mass blocks are pushed and obtain an initial velocity v0 parallel to the axis of the storage bin. Due to the fact that the axes of the 4 mass block storage bins have a certain angle with the axis of the launching device, the mass blocks will move radially during flight, thereby pulling and unfolding the net body.

[0044] This launching device is composed of a base, a power device, a launcher and an interception net. The base adopts a design that can be adjusted at multiple angles to adapt to different combat environments and can be folded for easy transportation and storage. The power device uses compressed air as the power source. High-pressure air is pre-filled in the air storage chamber. When the start switch is activated, the high-pressure air is instantaneously released to form a huge aerodynamic force, accelerating the launched object from rest to a high-speed projectile state.

[0045] The internal structure of the power device uses the pressure difference of compressed air in the cavity to open the air plug. Before being triggered, the launch tube is isolated from the outside world. The high-pressure air in the air storage chamber is sealed by the air plug and maintains the airtight state of the system. When the launch button is pressed, the air inlet of the small air chamber is communicated with the outside world, causing the pressure difference to increase rapidly, making the piston and the air plug retreat rapidly, and the high-pressure air instantaneously enters the launch tube, pushing the launched object to move at high speed. This process uses the pressure difference between the large air chamber and the small air chamber to control the opening of the air plug, ensuring the stability and controllability of the launch.

[0046] The launcher consists of a launch tube, air chamber, valve core assembly, firing mechanism, trigger, carbon fiber cylinder, and outer casing. The carbon fiber cylinder is connected to the inflation valve via pipe threads and secured to the air chamber by the outer casing, providing a high-pressure gas source. During launch, the valve core assembly interacts with the valve core rod, retaining block, and valve core cap to control the release of high-pressure air. The air chamber cover, gasket, and cavity form a closed space, ensuring stable gas pressure. A pressure gauge monitors the air chamber pressure in real time to ensure system safety and operability.

[0047] The launcher is a trumpet-shaped structure, with four cylindrical storage compartments at its edges for storing the four masses of the interception net. The interception net is folded and placed in the center of the launcher, with the masses secured within the compartments. During launch, high-pressure air propels the masses, giving them an initial velocity v_0 along the axis of the compartment. Because the compartment axis is at a certain angle to the main axis of the launcher, the masses generate radial motion during flight, pulling the interception net into deployment.

[0048] As the mass moves through the air, the net gradually unfurls. Once the mass has completely cleared the launcher, the interception net, acting under the tensile force of the four masses, rapidly stretches to its fully deployed position. The interception net's structural design minimizes the effects of air resistance during deployment, ensuring a stable and uniform deployment. At the end of its flight, the mass lands in the target area, maintaining tension throughout the process to enhance interception effectiveness.

[0049] This launcher uses a carbon fiber high-pressure gas cylinder as its gas source, enabling at least two consecutive launches on a single charge, improving operational efficiency. After the interception mission is complete, the interception net and mass can be recovered using recovery equipment or manual means, refolded, and stored in the launcher for use in the next mission. The system is reloadable and re-launchable, adapting to a variety of tactical requirements.

[0050] The multi-point towed interception net launch device of the present invention can be widely used in four major fields: low-altitude security, military countermeasures, public safety, and space capture. Specific product forms include: 1) anti-UAV interception system, used for low-altitude defense in sensitive areas such as airports and military restricted areas; 2) non-lethal capture equipment, used as police riot control equipment for suspect subduing or mass incident control; 3) ship-borne / vehicle-mounted interception device, adapted to military platforms for intercepting small aircraft or suspicious targets at sea; 4) space junk capture device, which can be applied to the recovery of abandoned satellites or debris in low-Earth orbit through improvements. Its modular design supports rapid adaptation to different scenarios such as police, military, and civilian use. The core module can also be independently used as a high-pressure pneumatic launch platform to expand to derivative application fields such as fire rescue and maritime throwing.

[0051] The interception net is folded by the four-pointed star folding method to make it petal-shaped and placed in the launch tube.

[0052] Figure 8 It is a schematic diagram of the folding process of the interception net.

[0053] During the flight of the interception net, the interception net is subjected to the pulling force of four mass blocks and is quickly stretched to the fully deployed state, and then its deployed area gradually decreases. The flight distance, maximum deployed area holding time, etc. of the interception net are adjusted by adjusting the mass and launch angle of the launch mass block.

[0054] Figure 9 It is a schematic diagram of the in-air deployment of the interception net.
