Description

Technical Field

[0001] This invention belongs to the field of marine defense technology, specifically relating to a mobile, integrated surface and underwater maritime interception system. Background Technology

[0002] Existing maritime interception devices targeting surface suicide unmanned surface vessels, underwater torpedoes, and various submersibles suffer from numerous technical shortcomings. Firstly, they lack specificity, failing to simultaneously address the interception needs of multiple types of surface and underwater targets, and are ill-suited to the protection requirements of different scenarios such as anchorages, islands, and ports. Secondly, their complex structures, inconvenient disassembly and replacement, and large deployment workloads make them easily detectable by the enemy, resulting in poor flexibility in practical deployment. Thirdly, the lack of effective visual monitoring systems prevents real-time observation of interception effectiveness, hindering precise interception and coordinated swarm operations. These problems lead to insufficient defensive efficiency and combat capability of existing interception devices, making them inadequate to address the diverse maritime threats currently facing the world. Summary of the Invention

[0003] In order to solve the technical problems of existing maritime interception devices, such as weak targeting, inconvenient disassembly and deployment, invisible interception effect and complex structure, this invention provides a mobile integrated surface and underwater maritime interception system.

[0004] The technical solution adopted in this invention is: A mobile, integrated surface and underwater maritime interception system includes two floats and a net-retracting mechanism detachably connected between the two floats; each float is equipped with a thruster and a host computer.

[0005] Furthermore, the float is equipped with a navigation light pointing system and a high-precision satellite navigation and inertial navigation system. Both the navigation light pointing system and the high-precision satellite navigation and inertial navigation system are electrically connected to the host computer installed on the float. A mast is installed on the top of the float, and the mast is equipped with a camera of the 360° long-range omnidirectional video system and a signal antenna of the MESH self-organizing network marine base station. Both the 360° long-range omnidirectional video system and the MESH self-organizing network marine base station are wirelessly connected to the host computer.

[0006] Furthermore, the outer shell of the float is a cylindrical shell made of a polymer anti-corrosion material, and wave-resistant buffer components are embedded inside the float.

[0007] Furthermore, a telescopic rod is coaxially fixed to the lower part of the float, and the bottom end of the telescopic rod is detachably connected to the acoustic decoy system via a flange.

[0009] Furthermore, an anchoring system is installed at the lower end of the float.

[0010] Furthermore, the net-setting and net-retrieval mechanism includes a net-setting component, a net-retrieval component, and an intercepting net; the intercepting net, the net-setting component, and the net-retrieval component are all connected between two floats respectively. The net-setting component is used to adjust the distance between the two floats to set up the intercepting net; the net-retrieval component is connected to the intercepting net and is used to drive the intercepting net to fold and retrieve.

[0011] Furthermore, the netting assembly includes at least two scissor-type telescopic mechanisms, each of which is connected between two floats; the drive motor of each scissor-type telescopic mechanism is fixed to the outer wall of the corresponding float.

[0012] Furthermore, the net retrieval assembly includes a retrieval frame, a retrieval reel, a disc retrieval motor, and a traction rope. The retrieval frame is installed on the upper end of the mast of one of the two floats. The disc retrieval motor is installed on the retrieval frame. The retrieval reel is fitted onto the output shaft of the disc retrieval motor. One end of the traction rope is wound around the retrieval reel, and the other end of the traction rope is fixed to the mast of the other float. Multiple pull rings are provided at the upper end of the interception net, and all pull rings are hooked onto the traction rope. A lead hole is provided at the upper end of the retrieval frame for guiding the traction rope.

[0013] Furthermore, the host computer is an integrated operation console with a built-in main control module, display module, and command issuing module. The main control module is wirelessly connected to the navigation light pointing system, high-precision satellite navigation and inertial navigation system, 360° remote omnidirectional video system at sea, and MESH self-organizing network maritime base station.

[0017] To better understand the purpose, structure, and function of this invention, the invention will be described in further detail below with reference to the accompanying drawings.

[0018] like Figures 1-5As shown, the present invention provides a mobile integrated surface and underwater maritime interception system, which is a modular device combining mechanics, communication, and navigation. It includes two floats 5 and a net-retracting mechanism detachably connected between the two floats 5. Each float 5 is equipped with a thruster 8 to improve the maneuverability of the float 5, and each float 5 is equipped with a host computer.

[0019] The various structural components of the interception system are detachable, facilitating modular assembly and replacement.

[0020] The high-precision satellite navigation and inertial navigation system enables the system to achieve precise positioning at sea, while the navigation light pointing system 4 assists in nighttime positioning and swarm coordination; The 360° long-range omnidirectional video system 2 at sea collects images of maritime targets within a 15KM range and transmits the video information to the host computer's omnidirectional video panoramic perception and cluster interception command system at sea, enabling real-time monitoring and locking of targets; MESH self-organizing network marine base station 1 realizes wireless communication between multiple systems, providing a data transmission basis for cluster interception. The host computer issues interception instructions based on target information, which are transmitted to the receiving and extending network mechanism through the control module. The float 5 is equipped with a navigation light pointing system 4 and a high-precision satellite navigation and inertial navigation system. Both the navigation light pointing system 4 and the high-precision satellite navigation and inertial navigation system are electrically connected to the host computer installed on the float 5. The top of the float 5 is equipped with a mast 3, which is equipped with a camera of the marine 360° remote omnidirectional video system 2 and a signal antenna of the MESH self-organizing network marine base station 1. Both the marine 360° remote omnidirectional video system 2 and the MESH self-organizing network marine base station 1 are wirelessly connected to the host computer.

[0021] The outer shell of the float 5 is a cylindrical shell made of high-polymer anti-corrosion material, and the float 5 is equipped with wave-resistant buffer components.

[0022] The lower part of the float 5 is coaxially fixed with a telescopic rod 6. The bottom end of the telescopic rod 6 is detachably connected to the acoustic decoy system 7 through a flange. The acoustic decoy system 7 can be opened as needed to interfere with underwater sonar detection and improve the system's stealth.

[0023] The float 5 is equipped with a double-disc battery structure, or a hybrid oil-electric power supply float can be detachably attached to the outside of the float 5 to supply power to the float 5, navigation light pointing system 4, high-precision satellite navigation and inertial navigation system, 360° long-range omnidirectional video system 2, MESH self-organizing network marine base station 1, control module, and telescopic mast 6.

[0024] The dual-disc battery is suitable for short-term mobile deployment, while the hybrid oil-electric power supply float is suitable for long-term continuous deployment. Both can be disassembled and replaced as needed.

[0025] An anchoring system is installed at the lower end of the float 5.

[0026] The net-retrieval mechanism includes a net-setting component 11, a net-retrieval component 10, and an intercepting net 9; the intercepting net 9, the net-setting component 11, and the net-retrieval component 10 are all connected between the two floats 5. The net-setting assembly 11 is used to adjust the distance between the two floats 5 so as to open the interception net 9; The net-closing component 10 is connected to the intercepting net 9 and is used to drive the intercepting net 9 to fold and close.

[0027] The interception net 9 is made of high-strength tensile and shear resistant material, and can be replaced with ordinary protective net or metal net as needed.

[0028] The netting assembly 11 includes at least two scissor-type telescopic mechanisms, each of which is connected between two floats 5; the drive motor of each scissor-type telescopic mechanism is fixed on the outer wall of the corresponding float 5.

[0029] The scissor-type telescopic mechanism of this system is driven by a motor, and its basic principle is as follows: Figure 6 As shown, the drive motor drives the gear 19 to rotate, and the gear 19 drives the rack 20 to reciprocate linearly. The rack 20 is hinged to one of the links of the scissor lift assembly 18. The linear movement of the rack 20 drives the entire scissor lift assembly 18 to extend and retract.

[0030] The net retrieval assembly 10 includes a take-up frame 12, a take-up reel 13, a disc take-up motor 15, and a traction rope 14. The take-up frame 12 is installed on the upper end of the mast 3 of one of the two floats 5. The disc take-up motor 15 is installed on the take-up frame 12. The take-up reel 13 is fitted onto the output shaft of the disc take-up motor 15. One end of the traction rope 14 is wound around the take-up reel 13, and the other end of the traction rope 14 is fixed to the mast 3 of the other float 5. The upper end of the interception net 9 is provided with multiple pull rings 17, all of which are hung on the traction rope 14. The upper end of the take-up frame 12 is provided with a lead hole 16 for guiding the traction rope 14.

[0031] The reel motor 15 is a reversible motor that drives the take-up reel 13 to rotate and causes the traction rope 14 to wrap around or unwrap from the take-up reel 13. When the netting assembly 11 brings the two floats 5 closer together, the take-up reel 13 wraps around the traction rope 14. As the traction rope 14 shortens, it causes the interception net 9 to fold, similar to a curtain.

[0032] The host computer is an integrated operation console with a built-in main control module, display module and command issuing module. The main control module is wirelessly connected to the navigation light pointing system 4, the high-precision satellite navigation and inertial navigation system, the 360° remote omnidirectional video system 2, and the MESH self-organizing network maritime base station 1. The maritime omnidirectional video panoramic perception and cluster interception command system on the host computer is electrically connected to the display module to realize the real-time display of the target image.

[0033] The above-mentioned float 5 is the basic version. There are also several other subsystem structures that can be adapted to different scenarios. Each subsystem retains the modular assembly characteristics.

[0034] ① The mobile ByssusF: The float 5 is a cylindrical shape with a diameter of 1.5 meters, the twin hulls have a deployment width of 4 meters, the net span is 10 meters, it is equipped with a battery pack with a range of 3-6 hours, no anchoring system, and a DP positioning system that is electrically connected to a high-precision satellite navigation and inertial navigation system. ② Semi-motorized ByssusT: Single float 5 with a diameter of 2 meters, one of the two floats 5 is equipped with an anchoring system, battery capacity is expanded or a hybrid power supply system is optional, and the net retrieval mechanism is shared with the basic version; ③ Fixed Type ByssusH: Multiple long ropes are added along the lower edge of the underwater interception net 9 to intercept floating objects, forming the "beard" of the interception net 9. The "beard" is made of a special nylon composite material. After the interception net is submerged, the outer layer decomposes upon contact with water, and the "beard" floats automatically. When the propeller passes through this area, the negative pressure zone at the water inlet more easily attracts the "beard," thereby sucking the entire interception net into the engine to achieve the purpose of entanglement and interception. It can also change the trajectory of underwater weapons or the course of unmanned vessels, or even cause them to lose power. Both buoys 5 are equipped with independent mooring systems and use hybrid power. The high-end version Byssus-AI is equipped with an artificial intelligence control module and is electrically connected to the 360° remote omnidirectional video system 2 and the net retrieval mechanism.

[0035] Working principle: The system of this invention can be deployed by selecting the corresponding model of subsystem according to actual protection needs. The basic version can be used alone or combined to achieve cluster interception. The working process of each subsystem is as follows: 1. Mobile ByssusF: Suitable for the protection of naval force concentration areas. After receiving the deployment order, the ship releases the ByssusF system. After landing in the water, the system automatically rights itself, and the two floats 5 approach each other and navigate to the designated coordinate point under the guidance of a high-precision satellite navigation and inertial navigation system. The host computer issues a net-setting command, and the net-setting component 11 unfolds the intercept net 9, forming a dual-net interception state above and below water. The DP positioning system is activated to maintain the system's interception direction and coordinate point. After the interception mission is completed, the host computer issues a net-retrieval command, and the net-retrieval component 10 retracts the intercept net 9. The system navigates back to the ship's side under the guidance of a high-precision satellite navigation and inertial navigation system and is retrieved by the lifting mechanism. If the intercept net 9 is damaged, it can be directly jettisoned and replaced with a new net.

[0036] 2. Semi-mobile ByssusT: Suitable for all-weather surveillance of strategic home ports and bases. After the system is deployed in the port, the two buoys 5 navigate to the designated position at the sea outlet. The buoy 5 with the anchoring system anchors at a single point, and the host computer issues a net-laying command to deploy the intercepting net 9. The other buoy 5 adjusts the position of the intercepting net 9 within a small range according to the defense requirements of the sea lane. When our ships need to enter or leave the port, the host computer issues a net-retrieval command. After the ships pass, the net is automatically re-laid and the defense is restored. The intercepting net 9 can be replaced periodically during the system deployment period. In case of emergency, the anchoring system can be cut off and abandoned to achieve rapid withdrawal.

[0037] 3. Fixed ByssusH: Suitable for island and reef management. After the system is deployed near the island or reef, the two buoys 5 navigate to the designated defense point under the guidance of a high-precision satellite navigation and inertial navigation system. The first buoy 5 anchors and deploys the interception net 9. After adjusting to the preset interception direction, the second buoy 5 anchors and simultaneously releases the underwater floating interceptor "long whiskers" to complete the deployment. When an intruding vessel breaches the net, the "long whiskers" will seize the vessel's propeller, damaging its power system and achieving physical interception. After the deployment mission is completed, the anchoring structure is automatically abandoned, and the system is manually recovered after the net is retrieved. The Byssus-AI version analyzes the target information collected by the video system through the artificial intelligence control module and automatically issues the net deployment and retrieval commands, achieving an automatic interception efficiency of 95%.
