Description

Technical Field

[0001] The present invention belongs to but is not limited to the technical field of interception net launching, and in particular relates to a single-point training missile towing interception net launching device and method. Background Art

[0002] Nets are a common underwater tool, used in a wide range of applications, from fisheries to environmental protection. One important function is interception. For example, fishing nets intercept fish that enter the net, while nets are also often used in environmental protection to intercept floating or submerged solid waste.

[0003] Currently available underwater interception net casting devices utilize a three-point synchronous launch mechanism: three parallel launch tubes are positioned on a base, each containing a corresponding towing rope. The net is pre-stacked in a polygonal star-shaped configuration at each launch port. A spring limiter maintains tension during folding, and after deployment, the net is deployed using evenly spaced floats and counterweights. The device is powered by a spring energy storage system or a high-pressure gas shunt drive. Multiple towing ropes must be released precisely and synchronously, otherwise the net can easily twist or become entangled. Furthermore, the limiters fixed to each tube port make it difficult to ensure simultaneous unlocking of multiple nodes, resulting in uneven deployment speeds.

[0004] The aforementioned multi-point casting scheme presents technical challenges such as complex structure and difficult synchronization control. First, the numerous towing ropes and limiting mechanisms increase the size of the launch device, increasing manufacturing costs and making maintenance and folding preparation cumbersome. Second, the release timing of each launch port must be precisely adjusted. Any slight deviation in synchronization can cause the net to become partially over-tensioned or loose in the water, resulting in failure to hang the net or inaccurate interception. Finally, the mechanical limiting method of the fixed node cannot be quickly released in water, seriously affecting the efficiency and reliability of deployment. Summary of the Invention

[0005] In response to the problems existing in the prior art, the present invention provides a single-point training missile towing interception net launching device and method.

[0006] The present invention is achieved by providing a single-point training missile towing interception net launching device, comprising:

[0007] The launching device comprises a base, a power device and a launcher, wherein the power device is arranged on the base and the launcher is connected to the front end of the power device;

[0008] a training projectile, launched by the launcher, the distal end of the training projectile being connected to the interception net;

[0009] The interception net includes a net body, a towing rope, a water-soluble material, a mass block, and a non-uniform buoy. The towing rope is used to connect the training projectile and the interception net, and the water-soluble material is used to constrain multiple nodes of the interception net.

[0010] Mass block, set on the long side of the interception net;

[0011] The non-uniform buoy is set between the mass blocks on the long side connected to the towing rope.

[0012] Furthermore, the interception net can be folded in a four-pointed star folding manner and in a parallel folding manner.

[0013] Furthermore, the long side connected to the traction rope is provided with four mass blocks, and two non-uniform buoys are provided between adjacent mass blocks.

[0014] Furthermore, the water-soluble material is arranged at multiple nodes of the interception net, so that the interception net remains in a rope-like shape when launched.

[0015] Furthermore, the interception net is expanded in the longitudinal direction under the action of gravity and buoyancy in the water, and is provided with counterweight and buoyancy support by the mass block and the non-uniform buoy.

[0016] Furthermore, the launcher uses high-pressure gas to drive the training missile to launch, and after the training missile is launched, it pulls the interception net into the target area.

[0017] Another object of the present invention is to provide a method for launching a single-point training missile towing an interception net by a single-point training missile towing interception net launching device, comprising the following steps:

[0018] Step 1: Use high-pressure gas to launch a training projectile. The end of the training projectile is connected to the interception net. The training projectile is used to pull the interception net during launch. At the same time, water-soluble materials are used to constrain several nodes of the interception net in the circumferential direction to form a rope-like shape.

[0019] Step 2: After the training missile is launched, the interception net still maintains a rope-like posture in the air. When it falls into the water, the water-soluble material dissolves, the circumferential constraint disappears, and the interception net is pulled by the mass block below and self-expands in the longitudinal direction in the seawater, forming a suspended interception net.

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

[0021] First, the present invention provides a single-point training missile towing interception net launching device that can automatically deploy into water.

[0022] The present invention uses high-pressure gas to launch a training projectile. The end of the training projectile is connected to an interception net, and the training projectile is used to pull the interception net during launch. Simultaneously, a water-soluble material is used to circumferentially constrain several nodes of the interception net, forming a rope-like shape. After the training projectile is launched, the interception net maintains its rope-like shape in the air. When it falls into the water, the water-soluble material dissolves, eliminating the circumferential constraints. The interception net, pulled by the mass below, automatically unfolds longitudinally in the seawater, forming a suspended interception net.

[0023] Secondly, the present invention uses high-pressure gas to launch a training projectile with the end connected to the interception net, and uses water-soluble materials to circumferentially constrain the nodes of the interception net to form a rope-like structure. After entering the water, the water-soluble material dissolves and releases the constraint, so that the interception net is longitudinally expanded under the traction of the mass block to form a suspended barrier net, which can efficiently intercept fish, floating objects and shallow solid garbage. After its technology is transformed, it is expected to have significant commercial value in the fields of marine environmental protection (such as offshore garbage cleaning, port pollution prevention), military training (water target interception simulation) and fishery management (aquaculture area isolation). Through equipment sales, service leasing and military procurement models, with the advantages of rapid deployment, low cost and environmental protection, it is expected to achieve large-scale application in the emergency response, normalized pollution control and security training markets, creating sustainable economic benefits.

[0024] This invention fills a technological gap in the field of rapidly deployable waterborne interception systems, both domestically and internationally. It combines single-point high-pressure gas launch with a water-soluble, self-deploying interception net for the first time, overcoming the shortcomings of traditional interception nets, which rely on multi-vessel collaboration, have low deployment efficiency, and are difficult to dynamically adjust. It also addresses the complex structure and high recovery costs of existing training missile interception systems. Its innovation lies in its unique design of rope-like folding and water-soluble triggering for deployment, enabling the interception net to achieve stable aerial flight and automatic deployment upon entry into the water. This provides a more efficient and cost-effective solution for scenarios such as emergency management of floating garbage, dynamic interception in shallow waters, and target deployment for military training. Currently, no similar technology has been publicly reported domestically or internationally.

[0025] This invention successfully solves three technical challenges that have long plagued the field of water interception: First, traditional interception nets rely on manual deployment or complex mechanical devices, resulting in slow response speeds. This invention achieves rapid deployment in seconds through single-point launch of high-pressure gas. Second, existing interception systems struggle to balance stability in mid-air with reliability in underwater deployment. This invention creatively employs a rope-like folding structure constrained by water-soluble materials, achieving the first full automation of the "launch-flight-water entry-self-deployment" process. Third, it overcomes the high recycling costs and secondary pollution risks associated with interception nets used in military training and environmental protection applications. By designing a dissolvable constraint mechanism and replaceable mesh, this design significantly reduces operating costs while ensuring effective interception. These groundbreaking solutions address the long-standing and pressing need for efficient, environmentally friendly, and low-cost interception systems in areas such as emergency response, environmental governance, and military training.

[0026] This invention overcomes the industry's two main technical prejudices: that interception nets must rely on coordinated multi-point, multi-mechanism launches and that underwater deployment structures must rely on mechanical triggering mechanisms. By innovating a single-point high-pressure gas launch system combined with water-soluble intelligent material restraint, this solution overturns the complex and cumbersome design of traditional interception systems. By integrating water-soluble restraint technology with ballistic launch technology, this technology transitions the interception net from "passive mechanical deployment" to "active environmental response," demonstrating that a single-point launch system can also accomplish large-scale interception missions. This opens a new paradigm for the development of lightweight, intelligent, and cost-effective aquatic interception equipment. BRIEF DESCRIPTION OF THE DRAWINGS

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

[0036] like Figure 1 As shown, an embodiment of the present invention provides a method for launching a single-point training missile towing an interception net, comprising the following steps:

[0037] Step 1: Use high-pressure gas to launch a training projectile. The end of the training projectile is connected to the interception net. The training projectile is used to pull the interception net for launch. At the same time, water-soluble materials are used to constrain several nodes of the interception net in the circumferential direction to form a rope-like shape.

[0038] Step 2: After the training missile is launched, the interception net still maintains a rope-like posture in the air. When it falls into the water, the water-soluble material dissolves, the circumferential constraint disappears, and the interception net is pulled by the mass block below and self-expands in the longitudinal direction of the seawater to form a suspended interception net. The launch and self-expanding process is as follows: Figure 2 shown.

[0039] like Figure 3 As shown, a single-point training missile towing interception net launching device includes:

[0040] The launching device comprises a base, a power device and a launcher, wherein the power device is arranged on the base and the launcher is connected to the front end of the power device;

[0041] a training projectile, launched by the launcher, the distal end of the training projectile being connected to the interception net;

[0042] The interception net includes a net body, a towing rope, a water-soluble material, a mass block, and a non-uniform buoy. The towing rope is used to connect the training projectile and the interception net, and the water-soluble material is used to constrain multiple nodes of the interception net.

[0043] Mass block, set on the long side of the interception net;

[0044] The non-uniform buoy is set between the mass blocks on the long side connected to the towing rope.

[0045] like Figure 3 As shown, an embodiment of the present invention provides a single-point training missile towing interception net launching device, including a base, a power device is provided on the base, and a launcher is provided at the front end of the power device; the interception net is connected to the launcher through a towing rope.

[0046] like Figure 4 As shown, the interception net folding methods are: four-pointed star folding and parallel folding.

[0047] Furthermore, the interception net has mass blocks installed on the long sides parallel to the interception net, and non-uniform buoys are installed between the mass blocks on the long side connected to the towing rope. Specifically, there are four mass blocks installed on the long side connected to the towing rope, with two non-uniform buoys installed between each two mass blocks; and four mass blocks are installed on the side parallel to the long side.

[0048] Furthermore, the long side connected to the traction rope is provided with four mass blocks, and two non-uniform buoys are provided between adjacent mass blocks.

[0049] Furthermore, the water-soluble material is arranged at multiple nodes of the interception net, so that the interception net remains in a rope-like shape when launched.

[0050] Furthermore, the interception net is expanded in the longitudinal direction under the action of gravity and buoyancy in the water, and is provided with counterweight and buoyancy support by the mass block and the non-uniform buoy.

[0051] Furthermore, the launcher uses high-pressure gas to drive the training missile to launch, and after the training missile is launched, it pulls the interception net into the target area.

[0052] like Figure 5 As shown, the model of the underwater vehicle contacting a net-linked motion model operates in seawater. Two buoys suspend multiple counterweights in the seawater via a net. The tension between the buoys and the counterweights causes the net to deploy vertically, while the net remains largely unaffected horizontally and moves with the waves. When the vehicle vertically contacts the net at a certain speed, the net engages the buoys and counterweights in a linked motion.

[0053] During the launcher preparation phase, the power unit is rigidly coupled to the base, and the gas source pressure is transmitted to the launcher's rear chamber through a conduit. When the high-pressure gas is rapidly released, it pushes the training projectile forward along the central axis within the cylinder. The end of the tow rope is simultaneously stretched, ensuring that the interception net remains in a folded, rope-like state during the release process. The water-soluble material at the nodes maintains the initial tension between the grids. Because the tow rope is fixed to the launcher's mouth and connected to the training projectile, the acceleration at the moment of launch is evenly distributed along the tow rope to the long-side mass block and the non-uniform buoy node, allowing the net's folding structure to unfold in an orderly manner under the combined action of airflow and inertial force.

[0054] When the training missile and intercepting net enter the target area, the resistance of the seawater quickly intervenes, creating an upward buoyancy force from the buoys and non-uniform buoys, while the masses create a downward gravity gradient along the long sides of the net. The alternating arrangement of buoys and masses creates a longitudinal tension differential across the net. The buoyancy-gravity coupling effect along the longitudinal axis propels the net vertically along its course, while the less-stressed lateral portions oscillate slightly with the waves, maintaining horizontal flexibility.

[0055] When an underwater vehicle contacts the net, the connections between the net's nodes, the towing ropes, the buoys, and the mass form a multi-bar hinged linkage. The localized force generated at the contact point is transmitted through the soft structure to the buoy-mass system, causing it to undergo a micro-vertical displacement. The coupling of buoyancy and gravity ensures the overall structure remains stable underwater, forming a net-wrapped formation as the vehicle continues to advance, achieving towing and interception.

[0056] Subsequently, as the training projectile moves further, the traction force exerted by the towing rope on the net surface continues to be output, and the connection between the towing rope and the launcher bears the peak tension and transmits it to the ground fixed component through the base and the power device. The entire system relies on the sealing ring and guide sleeve assembled at the speaker mouth to achieve dynamic balance, and at the same time uses the asymmetric buoyancy distribution between the buoy and the counterweight to maintain the open plane of the net. Finally, while maintaining a stable underwater structure, the target body is radially constrained in the net.

[0057] The launch system of this invention uses high-pressure gas to propel a training projectile, launching it in a specific direction. The end of the training projectile is connected to an interception net via a tow rope. During launch, the interception net folds into a rope-like configuration. To ensure the interception net remains compact during launch, multiple nodes of the interception net are circumferentially constrained using water-soluble materials. This provides a more stable structure, reduces air resistance, and improves launch accuracy and effectiveness.

[0058] After the training round is launched, the interception net remains in its rope-like folded configuration and does not immediately deploy. The water-soluble material keeps the net compact in mid-air, reducing air resistance and ensuring it remains on its intended trajectory. This restraint effectively prevents the net from prematurely deploying in mid-air, minimizing trajectory deviations caused by net vibration or drag, and improving interception accuracy and stability.

[0059] When the training missile drags the interception net into the water, the water-soluble material rapidly dissolves, eliminating the net's original circumferential constraints. At this point, the net begins to slowly unfold in the water. Due to the presence of mass blocks along its long sides, gravity and the buoyancy of the water cause the net to self-unfold longitudinally, ultimately forming a suspended arresting net, and the interception zone becomes effective.

[0060] To ensure stable underwater deployment of the interception net, the present invention employs non-uniform buoys between the long-side masses. This ensures proper buoyancy control in the water, preventing violent swaying due to currents or external disturbances. Furthermore, the even distribution of these non-uniform buoys between the four masses connected to the towing rope effectively regulates the net's stress state, preventing deformation or drift due to local imbalances and thus improving its stability.

[0061] When an underwater vehicle strikes the interception net vertically at a certain speed, the impact of the vehicle will be felt within the net, causing the floats and counterweights to move in conjunction with each other. Because the floats provide buoyancy and the counterweights provide gravity, the two are connected by the net, forming a structure that expands vertically but moves freely horizontally. This means that under the influence of external factors such as waves, the interception net can move with the water, yet still effectively absorb the impact energy when impacted by the vehicle, ensuring effective interception.

[0062] After completing its interception mission, the interception net can be collected using a specially designed recovery system. This recovery process utilizes the buoyancy provided by the towing rope and buoys to retract the net in a four-pointed star or parallel folding pattern. The net can then be salvaged using offshore vessels or specialized recovery equipment. This design improves the interception net's reusability, reduces its operating costs, and enables rapid deployment and recovery for different missions.

[0063] The interception net system of the present invention can be widely used in fields such as marine environmental protection (interception of offshore floating garbage, emergency control of port oil pollution, and blocking of pollutants at river estuaries), military security (rapid deployment of water targets, patrol and interception in border waters, and deployment of anti-terrorism and anti-infiltration barriers), fishery management (isolation and protection of aquaculture areas, dynamic fencing of rare fish protection areas, and interception of illegal fishing), and water conservancy projects (cleaning of floating objects in reservoirs, and garbage protection at the water inlets of hydropower stations). Its rapid deployment, adaptive deployment, and environmentally friendly and degradable characteristics make it particularly suitable for water interception needs that require immediate response, large-scale coverage, or ecologically sensitive scenarios.

[0064] The present invention employs two buoys at either end of the interception net, with multiple counterweights evenly spaced below. This structure significantly improves the interception net's stability during flight, ensuring it maintains a nearly straight line upon entering the water. This design effectively overcomes the technical drawbacks of traditional single-counterweight interception nets, which are prone to imbalance and difficulty in deployment. The interception net is deployed using a parallel folding method.

[0065] Figure 6 Interception net design and folding

[0066] At the same time, after the multi-weighted interception net enters the water, it can significantly improve the deployment performance and stability of the net in the water; through multi-point balanced traction, it ensures that the interception net is quickly deployed vertically and maintains an ideal posture to avoid entanglement or tilting; at the same time, the counterweights can adapt to changes in water flow and seabed topography, preventing the net from getting stuck on the bottom and being damaged while ensuring the bottom sealing; the evenly distributed counterweights also enhance the system's fault tolerance, and even if individual counterweights fail, it will not affect the overall function, thereby achieving reliable interception under various hydrological conditions.

[0068] The multi-weight interception net can be deployed quickly in water, and in calm waters it can reach over 75% deployment within one minute. Deployment of the interception net can be accelerated by increasing the weight of the counterweight and the volume of the buoys.
