Description

TECHNICAL FIELD

[0001] The present application relates to a handheld net capture device and its use method, which is suitable for the technical field of net capture devices. BACKGROUND

[0002] The handheld net capture device has important application value in the field of defense. In the police capture scene, it can be used to capture dangerous personnel such as armed gangsters and terrorist elements in densely populated places such as urban streets and residential areas; in the aspect of anti-UAV defense, it can be applied to the periphery of key infrastructure such as airports, military bases, and nuclear power plants to capture illegally intruding UAVs; in the field of military defense, it can be used to deal with enemy small water reconnaissance equipment, unmanned boats, and other single-person targets in island defense, border patrol, and other scenes. Its technical path includes launch device design (involving power systems such as compressed air, gunpowder gas, and electromagnetic launch, as well as precise aiming and intelligent control systems for launch control), capture net technology (focusing on net material and structure such as high-strength fiber material and different net structures, as well as net deployment methods such as explosion, mechanical, and pneumatic deployment), and recovery system (such as landing recovery, automatic pullback recovery, etc.). The use method covers preparation, aiming, and launching in police capture, target monitoring and locking, launching and recovery in anti-UAV scenes, and alerting, finding targets, intercepting, and disposing in military defense.

[0003] Although the existing net capture device meets the defense needs to some extent, it still has many defects and limitations. In terms of power and launching, the net capture device based on traditional spring compression principle has simple structure and high reliability, but the stress form of the spring hinders the effective range of the net. Using gunpowder gas as the launching power of the net capture device can store for a long time and has a long range, but gunpowder is an explosive, which has certain safety risks in use, storage, and transportation. Using a general type of carbon dioxide gas cylinder as the launching power can effectively avoid the shortcomings of traditional spring compression and gunpowder, and it has small size and suitable launching distance, but the carbon dioxide gas cylinder is also a high-pressure container, which still has different degrees of safety risks in normal storage and transportation.

[0004] The limitations of the existing net capture device mainly reflect in the following aspects:

[0005] 1. Insufficient range, for the spring compression type net capture device, its range is limited by the size of the spring, which has the defect of insufficient range of the capture net.

[0006] 2. Insufficient environmental protection, for the net capture device using explosive chemicals, a large amount of harmful gas is generated during launching, which does not meet the current environmental protection policy.

[0007] 3. Inadequate safety, both carbon dioxide gas cylinders and pyrotechnic agents as a network of launch devices will be powered in the process of transportation, storage and other hazards.

[0008] 5. Lack of maintenance, for carbon dioxide gas cylinder network capture device, because the gas cylinder is a high pressure container, in the usual maintenance and maintenance needs to be in accordance with the rules of the maintenance and maintenance of hazardous chemicals.

[0009] 6. High cost, uneconomical, no matter what way to launch the network capture device, is basically a one-time product, so the overall economic benefit is poor. SUMMARY

DETAILED DESCRIPTION

[0050] In order to make the purpose, technical scheme and advantages of the present application more clear, the embodiments of the present application will be described in detail below with reference to the drawings. It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other arbitrarily without conflict.

[0051] As shown in Figures 1-3 , the present application proposes a reusable handheld net capture device, which comprises an energy storage module 1, a trigger control module 2 and an execution module 3. The energy storage module 1 provides a storage space for the power source of the launch of the capture net, is connected with the trigger control module 2 by threaded connection, reduces the waste of equipment space, and the tail of the module can be filled with high-pressure gas; the energy storage module 1 is independent of the handheld net capture device, and when not in use, the inside can not be filled with gas to ensure the safety of the entire handheld net capture device during transportation and storage, and when in use, high-pressure gas can be quickly filled through the inflation interface on site. The two ends of the trigger control module 2 are connected with the energy storage module 1 and the execution module 3 respectively; the execution module 3 is provided with a capture net 4; the energy storage module 1 is provided with a gas cylinder 11 for storing high-pressure gas; the trigger control module 2 is used for triggering the release of high-pressure gas in the energy storage module 1 and controlling the directional flow of high-pressure gas to the execution module 3; the execution module 3 is used for driving the capture net 4 to launch according to the high-pressure gas provided by the energy storage module 1. The reusable handheld net capture device proposed by the present application has no pyrotechnics inside, no any high-pressure gas during storage and transportation, and can be maintained according to ordinary equipment, which can realize reuse in terms of economic benefit, thereby effectively reducing the use cost; and can solve the problems of insecurity, short range, non-reusability and high cost of the existing handheld net capture device during storage and transportation.

[0052] As shown in Figures 4-7As shown, in some embodiments, the gas cylinder piece 11 is used to store high-pressure gas, while providing the necessary gas source for energy release of the fire extinguishing device. The high-pressure gas is preferably nitrogen or a special propellant gas, which can be an inert gas such as CO2. The material of the gas cylinder piece 11 can be selected according to the nature of the gas to be stored, the overall storage pressure, the working environment, and the specific application scenario, and can be set to metal or non-metal material, non-metal such as high-strength engineering plastic PEEK, Ultem, glass fiber reinforced composite material, etc., suitable for lightweight, low cost or specific EMC requirements; metal materials such as stainless steel 304 / 316, titanium alloy TC4, high-strength aluminum alloy 7075-T6, special steel, etc., suitable for high pressure, high reliability, corrosion resistance or working in extreme mechanical environment; the gas cylinder piece 11 is sealed and fixed in the interior of the entire energy storage module 1 by high-strength threaded connection. One end of the energy storage module 1 is connected with the excitation control module 2 through threaded connection; the other end of the energy storage module 1 is provided with a mounting tail shell 13; the mounting tail shell 13 is provided with a one-way valve 12, which can communicate with the gas cylinder piece 11; the mounting tail shell 13 is also provided with a bayonet, and the mounting tail shell 13 is connected with the gas source through the bayonet and fills the high-pressure gas into the gas cylinder piece 11 through the one-way valve 12. Specifically, the one-way valve 12 is a precision control element for precisely controlling the flow direction of high-pressure gas, ensuring that high-pressure gas can only be filled into the gas cylinder piece 11 and can flow from the gas cylinder piece 11 to the subsequent execution module 3 in one direction, preventing gas backflow to ensure effective energy output, and preventing external medium from flowing into the gas cylinder piece 11 to cause danger. The core sealing and pressure-bearing parts of the one-way valve 12 (such as valve core, valve seat) are usually made of high-precision machined metal materials (such as brass, stainless steel 304 / 316, aluminum alloy, etc.) to ensure excellent wear resistance, corrosion resistance and sealing performance, and the valve body part can be made of metal or high-strength engineering plastic according to specific requirements. The one-way valve 12 is reliably connected in series with the gas inlet of the gas cylinder piece 11 through precise threads and interference fit. The mounting tail shell 13 can be used to fix and protect the gas inlet end (including the one-way valve) of the gas cylinder piece 11, and in specific applications, it also bears the functions of guiding the flow direction of high-pressure gas, restricting the energy release path, directly pushing the execution module or cooperating with the execution module. The mounting tail shell 13 is firmly connected to the tail end of the gas cylinder piece 11 through the bayonet lock.

[0053] As shown, Figures 4-7 The excitation control module 2 is the core control unit of the high-pressure gas release system, mainly including high-pressure gas release trigger control and gas directional release and energy regulation.

[0054] The high-pressure gas release trigger control is to ensure the safety and controllability of the high-pressure gas release process. This module adopts a double-redundancy safety lock mechanism, and an insurance and a switch are arranged between the energy storage cylinder and the execution module. The default state is in a normally closed state. Only when the device receives double-verification signals, the execution module will perform operations.

[0055] In the process of directional gas release and energy regulation, once the net trapping device confirms that the release conditions are met, the high-pressure gas flows through the gas cylinder 11 into the excitation control module 2 and finally into the gas guide pipeline of the execution module 3.

[0056] like Figure 5 As shown, in some embodiments, the excitation control module 2 includes a one-way air inlet 21, a valve core module 22, a converter 23, a mounting base 24, and control components. The one-way air inlet 21 is a one-way valve, a precision control element used to precisely control the flow direction of high-pressure gas, ensuring that high-pressure gas can only flow from the energy storage module 1 to the execution module 3, preventing gas backflow to ensure effective energy output, and preventing external media from flowing back into the gas cylinder and causing danger. The one-way air inlet 21 is reliably connected in series between the excitation control module 2 and the energy storage module 1 through precision threads and interference fit. Specifically, one end of the one-way air inlet 21 is fixedly connected to one side of the mounting base 24, and the other end of the one-way air inlet 21 is threadedly connected to one end of the energy storage module 1, and can communicate with the gas cylinder 11 to realize gas guidance. The valve core module 22 is movably mounted within the cavity of the fixed base 24. Driven by the compression spring 27, the valve core module 22 can open the valve core of the one-way air inlet 21, allowing the high-pressure gas from the gas cylinder 11 to enter the execution module 3 through the cavity, thereby driving the capture net 4 to launch. One end of the converter head 23 is fixedly connected to the other side of the fixed base 24; the converter head 23 is connected to the launch tube 31 and the cavity of the execution module 3 through a gas guide pipe. The control component is movably mounted on the fixed base 24. By being movably connected to the valve core module 22, the control component restricts the movement of the valve core module 22 within the cavity, thus blocking the high-pressure gas from the gas cylinder 11 from entering the cavity. Furthermore, by being movably connected to the valve core module 22, the control component allows the compression spring 27 to drive the valve core module 22 to move within the cavity and open the valve core of the air inlet 21, thereby allowing the high-pressure gas from the gas cylinder 11 to flow to the launch tube 31.

[0057] The valve core module 22 is the core actuator in the activation control module 2 that realizes the gas on / off switching, and is preferably a mechanical transmission assembly. The control components include the steel ball in the safety assembly 25 and the activation assembly 26. (Reference) Figures 4-7As shown, the left side of the valve core module 22 is connected with the compression spring 27, and when the net catching device is not activated, the valve core module 22 is limited by the first steel ball of the safety assembly 25 and the second steel ball of the activation assembly 26, at this time the compression spring 27 is in a compressed state. When the net catching device is activated, the first steel ball and the second steel ball are pushed into the docking groove of the valve core module 22, and the limitation of the valve core module 22 is released, at this time the compression spring 27 pushes the valve core module 22 to the right and opens the valve core of the one-way air inlet piece 21, so that the high-pressure gas of the gas cylinder piece 11 flows out. The valve core module 22 directly opens the valve core of the one-way air inlet piece 21 through its axial movement when the compression spring releases the elastic potential energy, thereby removing the blocking state of the one-way air inlet piece 21 to the high-pressure gas and establishing the gas flow path from the energy storage module 1 to the execution module 3. Through precise cooperation with the one-way air inlet piece 21, the valve core module 22 ensures that the high-pressure gas only flows in one direction under the driving of the compression spring, avoiding abnormal opening caused by accidental touch or reverse pressure, and is the key intermediate link connecting the spring power and gas transmission.

[0058] The conversion head module 23 is the connection interface between the trigger control module 2 and the execution module 3. The conversion head module 23 is a transition assembly of the gas transmission channel, which functions to transmit the high-pressure gas output by the one-way air inlet piece 21 to the launch barrel 31 of the execution module 3 through reliable sealing connection, ensuring the directionality and sealing of the high-pressure gas in the transmission process and avoiding leakage or pressure loss. The conversion head module is usually designed as a standardized interface, which can be adapted to different specifications of the execution module, thereby improving the universality of the control trigger module.

[0059] The activation assembly 26 is the human-computer interaction trigger component of the trigger control module, specifically an unlocking mechanism for limiting the activation spring. The activation assembly 26 is designed to release the limiting state of the activation spring through a pressing operation: in the initial state, the switch module fixes the spring through the internal limiting structure, so that the spring remains in the compressed energy storage state; when the activation pin 261 is pressed, the limiting structure is released, and the compression spring 27 loses the constraint and pushes the valve core module to act under the action of the elastic potential energy, thereby starting the entire gas trigger process. The activation pin 261 realizes active control of the release of high-pressure gas through the simple operation logic of “pressing-unlocking”, ensuring the safety and controllability of the trigger process.

[0060] The fixed seat 24 is the core structure carrier of the trigger control module 2, which functions through four aspects of “support-sealing-connection-positioning”: it provides stable installation reference for precise components such as valve core module, compression spring, activation spring, safety spring, steel ball, etc., guarantees the safety of high-pressure gas path through rigid connection with the module body, and serves as the connection bridge of the one-way air inlet piece and the conversion head, ensuring the reliability of the entire trigger control module under complex working conditions.

[0061] As shown in FIG. 1, the trigger control module 2 is composed of a one-way air inlet piece 21, a valve core module 22, a conversion head module 23, an activation assembly 26, a fixed seat 24, and a compression spring 27. Figures 6-7As shown, in some embodiments, the control component includes an insurance component 25 and an activation component 26; the insurance component 25 is arranged at the upper end of the fixed seat 24; the insurance component 25 can be clamped with the valve core module 22 to limit the movement of the valve core module 22 in the cavity; or, the insurance component 25 can be non-clamped with the valve core module 22 to achieve unlocking with the valve core module 22; the activation component 26 is arranged at the lower end of the fixed seat 24; the activation component 26 can be clamped with the valve core module 22 to limit the movement of the valve core module 22 in the cavity; or, the activation component 26 can be non-clamped with the valve core module 22 to activate the movement of the valve core module 22 in the cavity; when the insurance component 25 is in a non-clamped state with the valve core module 22, and the activation component 26 is in a non-clamped state with the valve core module 22, the valve core module 22 is driven by the compression spring 27 to move in the cavity, thereby pushing open the valve core of the air inlet component 21.

[0062] As shown in Figures 6-7 , 11-14, the design principle of the insurance component 25 is to convert the "operation sequence" into "structural constraint" through physical interlocking, while ensuring the convenience of human-computer interaction, and eliminating the safety hazard of accidental triggering from the hardware level. The self-locking function of the insurance component 25 is realized based on four parts of the insurance pin 251, the sliding cover 252, the first steel ball 254 and the insurance spring. The insurance pin 251 is designed with a stepped disc protrusion 255, and the sliding cover 252 is designed with a stepped annular groove 256. When the insurance pin 251 is not pressed, the stepped disc protrusion 255 of the insurance pin 251 tightly fits with the stepped annular groove 256 of the sliding cover 252, at this time the first steel ball 254 connected with it is in an uncompressed state, and the steel ball limits the movement of the valve core module 22; when the insurance pin 251 is not locked, it can freely move in the sliding cover 252; when the insurance pin 251 is rotated and self-locked, the upper surface of the stepped disc protrusion 255 of the insurance pin 251 is stopped by the lower surface of the stepped annular groove 256 of the sliding cover 252, limiting its position, so that it cannot be pressed. When the insurance pin 251 is pressed and rotated, at this time the stepped disc protrusion 255 of the insurance pin 251 moves downward and rotates to the non-stepped annular groove 256 position of the sliding cover 252 to limit its locking, at the same time the insurance pin 251 extrudes the first insurance spring 253, and pushes the first steel ball 254 of the limiting valve core into the first butt joint groove of the valve core module, thereby releasing the limiting of the valve core module by the insurance component. The insurance component 25 is suitable for scenes with extremely high safety and reliability requirements.

[0063] Further, the insurance module 25 has:

[0064] First, misoperation protection

[0065] (1) Double confirmation mechanism: force the user to complete the operation in two steps (first insurance, then activation), to avoid accidental triggering of the execution module due to single misoperation, causing the device to start incorrectly.

[0066] (2) Reducing the risk of human error: especially suitable for high-frequency operation or high-stress environment, reducing the operator's attention dependence through physical structure limitation.

[0067] Second, state visualization and feedback

[0068] (1) Operation state indication: the position of the safety pin (extended / retracted), the identification of the sliding cover (color, scale) visually displays whether the module is in the "triggerable" state, facilitating the operator to quickly confirm.

[0069] (2) Mechanical interlock feedback: the safety pin can be rotated after being pressed, and the safety pin is self-locked after rotation to confirm the effectiveness of the operation.

[0070] As shown in Figures 6-7 some embodiments, the safety assembly 25 includes a safety pin 251, a first safety spring 253, a second safety spring 257, and a first steel ball 254; the upper end of the fixed seat 24 is provided with a safety through hole, and the upper end of the valve core module 22 is provided with a first docking groove, the safety through hole and the first docking groove can be mutually docked and communicated; the first safety spring 253 is sleeved on one end of the safety pin 251 and abuts against the safety through hole, so that the safety pin 251 can be telescopically arranged in the safety through hole; the second safety spring 257 is arranged in the docking groove; the safety pin 251 is movably arranged in the safety through hole; in the natural state, at least a part of the first steel ball 254 is located in the safety through hole and abuts against the safety pin 251, and at least another part of the first steel ball 254 is located in the first docking groove and abuts against the second safety spring 257, so that the valve core module 22 is in the clamping state; when the safety pin 251 is compressed to a preset position under force, the entire first steel ball 254 is just located in the first docking groove, so that the valve core module 22 is in the non-clamping state.

[0071] As shown in Figures 8-10As shown, in some embodiments, the activation component 26 includes an activation pin 261, a first activation spring 262, a second activation spring 264, and a second steel ball 263; the lower end of the fixing base 24 is provided with an activation through hole, and the lower end of the valve core module 22 is provided with a second mating groove, the activation through hole and the second mating groove can be connected to each other; the first activation spring 262 is sleeved on one end of the activation pin 261 and abuts against the activation through hole, so that the activation pin 261 can be telescopically disposed in the activation through hole; the second activation spring 264 is disposed on the... The second mating groove is located within the activation pin 261, which is movably disposed within the activation through hole. In its natural state, at least a portion of the second steel ball 263 is located within the activation through hole and abuts against the activation pin 261, while at least another portion of the second steel ball 263 is located within the second mating groove and abuts against the second activation spring 264, thereby causing the valve core module 22 to be in a snap-fit ​​state. When the activation pin 261 is compressed to a preset position, the entire second steel ball 263 is located within the second mating groove, thereby causing the valve core module 22 to be in a non-snap-fit ​​state.

[0072] The execution module 3 is the ultimate embodiment of the "functionality" of the net-catching device, a core functional unit integrating energy conversion, overload protection, and reliable execution. The execution module directly receives high-pressure gas from the energy storage module, converting the instantaneous energy of the high-pressure gas into the precise kinetic energy of the net, driving the external load (net) to complete the predetermined action. Its design must balance the requirements of explosive force, output force, speed, stroke, and load matching. The execution module 3 not only fits the compact space of handheld devices but can also achieve intelligent control through the expansion of sensors.

[0073] like Figures 1-10 As shown, in some embodiments, the execution module 3 includes a housing 32 and an inner cover 33; the housing 32 and the inner cover 33 are respectively horn-shaped structures; the inner cover 33 is fixedly disposed inside the flared opening of the housing 32 and is coaxially disposed with the housing 32; at least three launch tubes 31 are evenly disposed in the circumferential direction of the flared opening and are located between the inner wall of the housing 32 and the outer wall of the inner cover 33; one constricted end of the housing 32 is fixedly connected to the conversion head 23, so that the launch tubes 31 communicate with the cavity; the capture net 4 is housed inside the inner cover 33; each traction block 41 of the capture net 4 is movably disposed inside each launch tube 31; each traction block 41 is connected to the capture net 4 through a wire so as to drive the capture net 4 to launch and unfold.

[0074] The traction block 41 is the core mechanical component in the execution module that enables the fixing of the capture net and the transmission of power. Its functions include two aspects:

[0075] First, the four legs of the capture net are rigidly fixed to the traction block with screws to form a stable connection structure, ensuring that the capture net remains in a retracted state and can be reliably stored in the inner cover when not being launched;

[0076] Second, when the high-pressure gas in the launch cylinder impacts the traction block, the traction block, as a force carrier, converts the pressure energy of the high-pressure gas into the kinetic energy of its own motion, pushing the capture net out of the restriction of the internal cover through axial linear motion, and shooting out along the direction of the launch cylinder at high speed, completing the release action of the capture net. The precise fit of the traction block and the inner wall of the launch cylinder (such as low-friction coefficient surface treatment) can reduce the movement resistance and improve the launching efficiency.

[0077] The internal cover 33 is a functional component in the execution module 3 for receiving and preliminarily restraining the capture net, which is a "pre-loaded containment structure of the capture net". The internal cover 33 functions to provide a closed and stable storage space for the capture net in the non-firing state, avoiding the capture net from scattering due to accidental collision or external force pulling through physical shielding; at the same time, the inner wall shape of the internal cover matches the folding form of the capture net, which can preliminarily guide the initial unfolding direction of the capture net during launching, cooperating with the linear motion of the traction block to ensure the orderly shooting of the capture net along the axis direction of the launch cylinder, reducing the energy loss or launching deviation caused by disordered unfolding.

[0078] The shell 32 is the protection and structural support body of the execution module 3, which is the safety barrier and mechanical bearing frame of the mechanical components. Its main functions include:

[0079] First, the shell structure with high-strength material provides physical protection for the internal launch cylinder, internal cover and traction block, resisting external collision, extrusion or environmental erosion, and ensuring the structural integrity of the execution module under complex working conditions;

[0080] Second, the shape design of the shell optimizes the layout of the internal cavity to provide precise positioning support for each component, maintaining the overall rigidity and assembly accuracy of the execution module.

[0081] The launch cylinder 31 is a key channel component in the execution module 3 that realizes the conversion of high-pressure gas energy and the launching of the capture net, which is a power transmission pipeline driven by gas.

[0082] The functions of the launch cylinder 31 include:

[0083] First, as an input channel for high-pressure gas, it receives high-pressure gas transferred from the excitation control module through the conversion head module, and concentrates the pressure energy of the gas on the surface of the traction block to drive the traction block to move linearly at high speed;

[0084] Second, through the constraint characteristics of the cylindrical structure, the movement direction of the traction block is limited (along the axis of the launch cylinder), ensuring that the capture net shoots out along the predetermined trajectory at high speed, avoiding capture failure due to direction deviation;

[0085] Third, the inner wall of the launch cylinder is usually smooth to reduce the friction resistance with the traction block, maximize the conversion efficiency of gas energy, and improve the launching speed and range of the capture net.

[0095] S8: After hearing the sound of emission and observing that the capture net 4 has been completely emitted, observe whether the capture net 4 accurately covers the capture object; if successful capture, the operator should slowly and smoothly fold the connecting rope between the net capture device and the captured object or directly approach the captured object carefully to safely recover it; if the capture fails or needs to be tried again, the state of the net capture device, the remaining working gas pressure and the capture net should be checked, and under the premise of safety, the capture task can be performed again after reloading or adjustment; during the entire operation process, the capture object and the surrounding environment should always be vigilant;

[0096] S9: After completing the capture task or determining that the device will not be used again, if there is still remaining working gas in the energy storage module 1 and it is not immediately used again after inflation, the remaining working gas should be safely released;

[0097] S10: Disassemble the various modules of the net capture device, clean, check and maintain the energy storage module and the capture net; if there are damaged parts or parts that have reached the end of their service life, they should be replaced in a timely manner. The maintained net capture device should be stored in a safe place with ventilation and dryness, where children cannot access, there is no corrosive gas, and there is no severe vibration, and good use and maintenance records should be kept.
