Description

TECHNICAL FIELD

[0001] The present application relates to the field of island military defense, in particular to an island reef underground fort anti-attack protection system and an anti-attack protection method. BACKGROUND

[0002] With the rapid development of modern military technology, island reef underground forts, as important defensive fortifications, are facing increasingly severe conventional weapon threats. Traditional underground fort protection structures mostly use reinforced concrete or steel plates, but in the face of multiple types of ammunition (such as armor-piercing bullets, thermal pressure bullets), their anti-penetration, anti-explosion and anti-thermal pressure capabilities are obviously insufficient. In addition, the existing camouflage technology of underground forts is relatively single, and it is difficult to cope with the precise positioning of multi-mode detection means such as high-resolution satellites, infrared imaging and radar, resulting in a significant reduction in its concealment. At the same time, the energy supply of the underground fort usually depends on external transportation or diesel generators, and in wartime it is easy to be paralyzed due to the interruption of supply lines.

[0003] Therefore, there is an urgent need for a new type of island reef underground fort protection technology that integrates active defense, intelligent repair and energy self-sustaining, to improve its survivability and sustained combat effectiveness in complex battlefield environments. SUMMARY

[0004] In view of the deficiencies of the prior art, the present application aims to provide a protection technology for island reef underground forts against conventional weapon attacks, which uses a composite biomimetic protection method to resist the combined attack of multiple types of ammunition, and by introducing various camouflage technologies and energy supply systems, to solve the problems of insufficient anti-penetration capability, poor concealment and insufficient endurance in existing underground fort protection, and to improve its survivability.

[0005] The technical solution of the present application is as follows:

[0006] The present application first provides an island reef underground fort anti-attack protection system, comprising:

[0007] An underground fort composite biomimetic protection system, which serves as an inner defense line against attack, ensures the structural integrity and functionality of the underground fort, and includes a main structure and a dome structure, the main structure includes inner self-repairing concrete and outer anti-penetration plates, and the dome structure includes a right triangular pyramid anti-explosion wave-absorbing structure;

[0008] A water area protection system, which serves as an outer defense line to interfere with detection, realizes the concealment and camouflage of the underground fort position, and includes underwater interference generators laid in the water area around the underground fort;

[0010] The energy supply system is arranged around the underground fortress to realize energy self-sufficiency of the underground fortress.

[0011] In a specific embodiment, the inner layer of self-repairing concrete uses a microbial-induced mineralization repair technology to implant Bacillus pasteurii at a concentration of greater than or equal to 10 6 CFU / g during concrete pouring to improve the self-repairing capability of the concrete.

[0012] In a specific embodiment, the outer layer of anti-penetration plates uses basalt fiber ceramic plates with a porosity similar to that of natural reefs, and is tightly attached to the surface of the inner layer of self-repairing concrete after pouring of the inner layer of self-repairing concrete through an adhesive. The gaps between the plates are filled with biomimetic silica gel with a color consistent with that of the reefs, and a biomimetic coating containing natural reef powder is sprayed on the surface to achieve a target roughness, so as to obtain strong anti-penetration capability.

[0013] In a specific embodiment, the dome structure comprises:

[0014] The steel skeleton concrete dome is internally arranged with vertical and circumferential steel skeletons, the vertical steel skeletons are pre-embedded in the inner layer of self-repairing concrete during pouring of the inner layer of self-repairing concrete, and a concrete hemispherical dome structure is externally poured to serve as a third-level protection.

[0015] The segmented arc-shaped steel plate is covered on the surface of the concrete dome by a plurality of arc-shaped steel plates to serve as a second-level protection.

[0016] The right triangular pyramid blast-resistant wave-absorbing structure is arranged and fixed on the outer side of the segmented arc-shaped steel plate along the surface of the concrete dome by a plurality of right triangular pyramid concrete geometric units through a bolt group, and a blast vent is formed at a key position to serve as a first-level protection.

[0017] The steel skeleton concrete dome, the segmented arc-shaped steel plate, and the right triangular pyramid blast-resistant wave-absorbing structure form a three-level gradient anti-impact protection layer.

[0018] In a specific embodiment, the included angle between the pyramid side surface and the bottom surface of the right triangular pyramid concrete geometric unit is 30° to 55°, a gap is left between the bottom surface and the arc surface of the arc-shaped steel plate and between adjacent structures as a blast vent to avoid energy accumulation, and a silicon carbide ceramic coating is sprayed on the pyramid surface to realize anti- penetration of a bullet.

[0019] In a specific embodiment, a micro plasma generator is embedded in the pyramid of the right triangular pyramid blast-resistant wave-absorbing structure to release a broadband electromagnetic pulse and actively perform electromagnetic interference when impacted.

[0020] In a specific embodiment, the underwater interference generator comprises underwater sonar arrays deployed in the water area around the fort, each of the underwater sonar arrays comprising retractable detection arms that extend to simulate natural tidal noise when turned on and retract into the interior for camouflage when turned off.

[0021] In a specific embodiment, the land interference generator comprises aerosol-plasma interference generators and ring-shaped ionization devices deployed in the land area around the fort, a plurality of the aerosol-plasma interference generators being arranged in a ring-shaped array around the fort, and the ring-shaped ionization devices being in ring-shaped connection with the plurality of aerosol-plasma interference generators, the aerosol-plasma interference generators rapidly releasing aerosol clouds containing metal particles to generate a plasma barrier in combination with the ring-shaped ionization devices to interfere with laser guidance, infrared imaging, and radar detection when an attack occurs, thereby protecting the fort.

[0022] In a specific embodiment, the energy supply system comprises wave energy conversion devices, turbine generators, and power storage devices, wherein the wave energy conversion devices are composed of a plurality of high-density polyethylene buoys connected by hinges to form an array that moves up and down with the waves, the movement of the buoys drives hydraulic cylinders to convert wave mechanical energy into hydraulic energy, the hydraulic energy compresses air into a buried gas storage tank, connects the turbine generators to generate electricity, and stores the electricity in the power storage devices.

[0023] The present application also provides an anti-impact protection method based on the above anti-impact protection system, comprising the following steps:

[0024] S10: The energy supply system is started, wave mechanical energy is converted into hydraulic energy by the wave energy conversion devices, turbine generators are driven to generate electricity, and the electricity is stored in the power storage devices to provide continuous energy for the fort composite biomimetic protection system, the water area protection system, and the land protection system;

[0025] S20: The water area protection system and the land protection system are deployed and activated, underwater sonar arrays are deployed in the water area around the fort, aerosol-plasma interference generators and ring-shaped ionization devices are deployed in the land area around the fort, and in the normal state, low-power standby is maintained to achieve concealment and camouflage of the fort location;

[0026] S30: Threat detection and interference response, when enemy detection or attack signals are detected, the underwater interference generator is started, the retractable detection arms of the underwater sonar arrays are extended to simulate natural tidal noise, and interfere with sonar detection; at the same time, the land interference generator is activated, the aerosol-plasma interference generators rapidly release aerosol clouds containing metal particles, and in combination with the ring-shaped ionization devices, generate a plasma barrier to interfere with laser guidance, infrared imaging, and radar detection;

[0027] S40: A three-tiered impact-resistant protective layer response. When an impact reaches the bunker's composite biomimetic protection system, the dome structure's triangular pyramidal anti-blast wave-absorbing structure serves as the first level of protection. It disperses the impact energy through the anti-blast wave-absorbing and explosion-venting channels on the sides of the pyramid. Upon impact, the embedded micro-plasma generator releases broadband electromagnetic pulses for active electromagnetic interference. The segmented arc-shaped steel plate serves as the second level of protection, further absorbing and dispersing energy. The steel-framed concrete dome serves as the third level of protection, ensuring structural stability. The outer penetration-resistant plate of the main structure resists the penetration of the projectile, while the inner self-healing concrete automatically repairs cracks after damage through microbial-induced mineralization repair technology.

[0028] S50: System self-sufficiency and recovery. The energy supply system continues to operate, ensuring that the protection system can quickly recover its functions after an attack. The inner self-healing concrete completes self-repair, and the water and land protection systems return to standby mode, maintaining the bunker's long-term concealment and protection capabilities.

[0029] The advantages of this invention compared to existing technologies are: it constructs a comprehensive protection system integrating concealment, resistance to attack, and sustainability, significantly improving the combat effectiveness and survival period of bunkers in modern warfare. Specifically, this can be better understood from at least the following aspects:

[0030] This invention presents a composite biomimetic protective system for bunkers, introducing biotechnology and biomimetic materials into military protective engineering. The self-healing concrete inner layer employs microbial-induced mineralization repair technology. By implanting a high concentration of Pasteurella multocida into the concrete, it achieves an intelligent repair function where the bacteria automatically activate to secrete calcium carbonate to fill damage when water seeps into cracks, significantly improving the structure's durability and battlefield survivability. The outer basalt fiber ceramic layer, precisely mimicking the porosity and surface roughness of natural reefs, combined with a biomimetic silicone filling process, not only achieves perfect camouflage and integration with the surrounding environment but also exhibits excellent penetration resistance, capable of withstanding combined attacks from various munitions. The synergistic application of these two technologies constructs a novel protective system that combines intelligent repair, efficient protection, and environmental adaptability. The outer layer provides rigid impact resistance, while the inner layer ensures self-repair, jointly achieving a technological breakthrough in lightweight, intelligent, and long-lasting military protective engineering. Compared to traditional protective structures, it has significant advantages in blast resistance, concealment, and maintenance costs, solving the pain points of traditional protective structures being bulky, vulnerable, and difficult to maintain.

[0031] In this invention's protective technology, the dome structure design achieves blast resistance, wave dissipation, and impact resistance through a three-tiered gradient protection system. The first tier employs an array of regular triangular pyramid blast resistance structures, optimizing the shock wave reflection path to scatter the blast shock wave in different directions. The second tier uses arc-shaped steel plates covering the concrete surface. The third tier is a cast-in-place steel-framed concrete dome structure, forming a complete gradient protection system. The regular triangular pyramid blast resistance structure integrates active defense functionality. It enhances penetration resistance by spraying a silicon carbide ceramic coating onto the pyramid surface, embedding a micro-plasma generator to actively release electromagnetic pulse interference guidance upon impact, and utilizing the gaps between adjacent structures as energy dissipation channels. This design, combining passive protection (geometric wave dissipation, gradient blast resistance) with active defense (electromagnetic interference), not only significantly improves blast resistance but also achieves an intelligent upgrade of the protective structure, providing stronger battlefield adaptability and survivability compared to traditional protective fortifications.

[0032] This invention combines a land-water protection system. A retractable underwater sonar array is installed around the bunker, whose coral reef-shaped shell and retractable detection arm can simulate natural tidal noise; the application of a land-based jamming generator can simultaneously counter multiple detection methods such as laser guidance, infrared imaging, and radar detection.

[0033] This invention incorporates an energy supply system into its protective technology. Modular wave energy conversion devices and battery packs are installed as auxiliary devices near the bunker, forming a tidal energy self-powered system to achieve energy self-sufficiency for the bunker and ensure its survival period in modern warfare environments.

In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0059] The implementation of the present invention will be described in detail below with reference to preferred embodiments.

[0060] Overall Figure 1 As shown in the figure, an island and reef bunker anti-attack protection system 100 provided by this invention mainly includes: a bunker composite bionic protection system 10, a water area protection system 20, a land area protection system 30, and an energy supply system 40. The water area protection system 20 and the land area protection system 30 serve as the outer defense line of the bunker, i.e., the first line of defense, used to interfere with detection and achieve concealment and camouflage of the bunker's location. The bunker composite bionic protection system 10 serves as the inner defense line, i.e., the second line of defense, used to resist attacks when the first line of defense is not fully functional or fails, ensuring that the bunker structure can maintain its integrity and functionality even under attack. The energy supply system 40 is located around the bunker to achieve energy self-sufficiency. The island and reef bunker anti-attack protection system 100 provided by this invention enables island and reef bunkers to withstand combined attacks from weapons such as armor-piercing projectiles and thermobaric projectiles, possessing advantages such as active defense, intelligent self-repair, and energy self-sufficiency.

[0061] For the bunker composite biomimetic protection system 10, see [link / reference]. Figure 2 , Figure 3 First, it includes the main structure 11, which serves as the main body of the bunker, including an inner layer of self-healing concrete 111 and an outer layer of anti-penetration plate 112.

[0062] In one specific embodiment, the inner self-healing concrete 111 utilizes microbial-induced mineralization repair technology, by implanting Bacillus pasteurellii (concentration ≥10) during concrete pouring. 6 (CFU / g), for example, using pre-encapsulated porous aggregates or microcapsules containing bacterial spores and nutrients. During construction, this repair agent is used as a special component, replacing a portion of the fine aggregate in the concrete mix in equal amounts. It is added to the mixer along with other raw materials and mixed evenly before normal pouring and curing to enhance the self-healing ability of the concrete. Simultaneously, nano-silica modifiers are added to improve the concrete's impermeability and slow down crack propagation. When cracks appear in the inner concrete layer and water seeps in, it can activate Pasteurella multocida to secrete calcium carbonate, quickly filling the damage to the inner cracks. It's easy to understand that Pasteurella multocida is readily available, and the inner self-healing concrete 111 can be made of ordinary concrete, high-strength concrete, reinforced concrete, or other specific forms.

[0063] In one specific embodiment, the outer anti-penetration plate 112 is made of basalt fiber ceramic plate. Multiple basalt fiber ceramic plates can be spliced ​​together, with a shape matching the inner self-healing concrete 111. The surface has a porosity similar to natural reef. The bottom of the basalt fiber ceramic plate is fixed to the base by anchor bolts. After the inner self-healing concrete 111 is poured, it is tightly bonded to the surface of the inner self-healing concrete 111 using adhesive. Furthermore, the gaps between adjacent plates can be further filled with biomimetic silicone matching the color of the reef, and the surface is sprayed with a biomimetic coating containing natural reef powder. Sandblasting is then used to achieve the target roughness to obtain strong anti-penetration capabilities.

[0064] In this embodiment, see continue to refer to Figure 3 The bunker composite biomimetic protection system 10 also includes a dome structure 12. The dome structure 12 first includes a triangular pyramid anti-blast wave-absorbing structure 121. The triangular pyramid anti-blast wave-absorbing structure 121 causes the incident ammunition to deflect and slide, reducing the probability of vertical impact.

[0065] In one specific embodiment, the dome structure 12 comprises a three-tiered impact protection structure consisting of a triangular pyramidal blast-resistant wave-damping structure 121, a segmented arc-shaped steel plate 122, and a steel-framed concrete dome 123 arranged sequentially from the outside in. The steel-framed concrete dome 123 has vertical and circumferential steel frames 1231 arranged inside. The vertical steel frames 1231 are pre-embedded in the inner self-healing concrete 111 during its pouring. The circumferential steel frames 1231 are surrounded by concrete to form a hemispherical dome structure, serving as the third level of protection. The segmented arc-shaped steel plate 122 consists of multiple arc-shaped steel plates covering the surface of the concrete dome, serving as the second level of protection. The triangular pyramidal blast-resistant wave-damping structure 121 is fixed to the outside of the segmented arc-shaped steel plate 122 by a group of bolts arranged in an array along the surface of the concrete dome, serving as the first level of protection. It is easy to understand that the first level of protection, the triangular pyramidal anti-blast wave-absorbing structure 121, can scatter the impact in different directions after being hit, reducing the probability of vertical impact; the second level of protection, the segmented arc-shaped steel plate 122, covers the surface of the concrete dome, further reducing the impact of conventional weapon attacks; the third level of protection is the cast-in-place steel frame concrete dome 123, thus forming a three-level gradient protection system to ensure that the main structure can still maintain its integrity and functionality when hit by conventional weapons.

[0066] In this embodiment, as Figure 4As shown, the triangular pyramidal blast-resistant shock absorption structure 121, serving as the first-level protective structure of the bunker dome, is composed of several triangular pyramidal concrete geometric units 1211. These units are arranged in a circular array along the dome structure to form a composite protection system, used to disperse the multi-directional loads of explosive shock waves (such as armor-piercing projectiles and thermobaric projectiles). The angle between the side and base of the pyramid is 30°~55°. This design optimizes the impact reflection path, utilizing the inclined surface of the pyramid to induce shock wave reflection and cancellation, significantly reducing peak overpressure compared to traditional structures. Furthermore, when the triangular pyramidal concrete geometric units 1211 are installed on the curved surface, they do not completely conform to the curved surface, creating gaps at the contact points. Gaps also form between adjacent triangular pyramidal concrete geometric units 1211, leaving gaps between adjacent structures as blast relief channels to prevent energy accumulation.

[0067] In addition, the surface of the pyramid is coated with a silicon carbide ceramic coating to resist the penetration of projectiles. A micro plasma generator is embedded inside the pyramid. Specifically, it is embedded in the pyramid during the casting process. When impacted, it releases a broadband electromagnetic pulse to interfere with guidance. It can actively conduct electromagnetic interference when it is about to be hit.

[0068] During actual installation, pre-embedded connectors are used on the dome surface for welding segmented arc-shaped steel plates 122; while prefabricated connectors 1212, such as pre-embedded reinforcing bars, are pre-embedded at the bottom of the regular triangular pyramidal concrete geometric unit 1211. Figure 5 As shown, holes are drilled or through holes are pre-drilled in the curved steel plate 122, and the regular triangular pyramidal concrete geometric unit 1211 is fixed by connecting bolts. Of course, welding can also be used for fixing, and bolted connections facilitate maintenance and replacement when the layout is damaged.

[0069] For details on water protection system 20, please refer to [link / reference]. Figure 1 , Figure 6 It first includes an underwater jamming generator 21 deployed in the waters surrounding the bunker. Specifically, the underwater jamming generator 21 can be formed by deploying an underwater sonar array in the waters surrounding the bunker. This array consists of several underwater sonars deployed in the waters surrounding the bunker. Each underwater sonar in the array includes a sonar body 211 and a retractable probe arm 212. A signal receiver is installed inside the circular rod of the probe arm to receive signals. When activated, the retractable probe arm 212 extends from the sonar body 211 to simulate natural tidal noise. When deactivated, the retractable probe arm 212 retracts into the sonar body 211 for camouflage. Figure 6 As shown, the sonar body 211 has a base, and in actual deployment, the underwater jamming generator 21 can also be fixed on the seabed around the bunker through the base.

[0070] Preferably, the outer shell of the sonar body 211 is biomimetic to the shape of a coral reef, and the sound intensity level is matched with the local tidal noise to mask the acoustic characteristics of the bunker location.

[0071] For example Figure 1 , Figure 7As shown, the land-based defense system 30 includes land-based jamming generators 31 deployed in the land surrounding the bunker. Specifically, the land-based jamming generators 311 consist of aerosol-plasma jamming generators 311 and a ring-shaped ionization device 312 deployed in the land surrounding the bunker. Multiple aerosol-plasma jamming generators 311 are arranged in a ring array around the bunker, and the ring-shaped ionization device 312 is arranged in a ring around the bunker and connected to the multiple aerosol-plasma jamming generators 311. In practice, storage tanks are pre-buried at concealed locations in the land surrounding the bunker to store aerosol liquid. In the event of an attack, the aerosol-plasma jamming generators 311 rapidly release aerosol clouds containing metal particles, which, combined with the ring-shaped ionization device 312, generate a plasma barrier to interfere with laser guidance, infrared imaging, and radar detection, thereby protecting the bunker.

[0072] For energy supply system 40, such as Figure 1 , Figure 8 As shown, it is deployed in the waters surrounding the bunker to achieve energy self-sufficiency for the bunker.

[0073] In one specific embodiment, the energy supply system 40 includes a wave energy conversion device 41, a turbine generator (not shown in the figure), and an energy storage device 42, forming a tidal energy self-powered system. Combined with the energy storage device 42, the energy self-sufficiency of the bunker is achieved.

[0074] In this embodiment, the wave energy conversion device 41 is composed of multiple high-density polyethylene pontoons 411. The lower part of the pontoon 411 is provided with blades 412, and the bottom is fixed by an underwater steel cable 43. It floats on the sea surface near the waters surrounding the bunker. The pontoon 411 moves up and down with the waves due to the action of the waves. During the movement of the pontoon 411, the blades 412 rotate at a preset maximum pitch angle. Due to the rotation of the blades 412, the hydraulic cylinder (the hydraulic cylinder is built into the pontoon, which is an existing structure) is driven to convert the mechanical energy of the waves into hydraulic energy. The hydraulic energy compresses the air into the air tank, connects to the turbine generator to generate electricity, and stores it in the energy storage device 42.

[0075] The buoys 411 are connected by hinges to form an array, with the spacing between adjacent buoys 411 being ≥20m to avoid wave interference effects.

[0076] The energy storage device 42 uses lithium iron phosphate battery packs, which are located in a suitable location on land surrounding the bunker, such as in an independent explosion-proof compartment underground. The power generated by the turbine generator is stored in the lithium iron phosphate battery packs. Each lithium iron phosphate battery pack module has a capacity of 50kWh, and they are connected in series to form a 1-2MWh energy storage system, equipped with liquid cooling and a battery management system.

[0077] like Figure 9 As shown, based on the anti-attack protection system provided in the above embodiments, its anti-attack protection method 200 includes the following steps:

[0078] S10: The energy supply system 40 is activated, and the wave mechanical energy is converted into hydraulic energy through the wave energy conversion device 41 to drive the turbine generator to generate electricity and store the electrical energy in the energy storage device 42 to provide continuous energy for the bunker composite bionic protection system 10, the water protection system 20 and the land protection system 30.

[0079] S20: Deployment and activation of the water area protection system 20 and the land area protection system 30; deployment of underwater sonar arrays in the waters surrounding the bunker; deployment of aerosol-plasma interference generator 311 and ring ionization device 312 in the land area surrounding the bunker; maintaining low power standby under normal conditions to achieve concealment and camouflage of the bunker's location.

[0080] S30: Threat Detection and Jamming Response. When enemy detection or attack signals are detected, the underwater jamming generator 21 is activated, and the retractable detection arm 212 of the underwater sonar extends to simulate natural tidal noise, interfering with sonar detection. At the same time, the land jamming generator 31 is activated, and the aerosol-plasma jamming generator 311 rapidly releases an aerosol cloud containing metal particles, which, combined with the ring ionization device 312, generates a plasma barrier to interfere with laser guidance, infrared imaging, and radar detection.

[0081] S40: Three-level gradient anti-impact protection layer response. When an impact reaches the bunker composite biomimetic protection system, the triangular pyramidal anti-blast wave-absorbing structure 121 of the dome structure 12 serves as the first level of protection, dispersing the impact energy through the anti-blast wave-absorbing and explosion-venting channels on the sides of the pyramid. When impacted, the embedded micro plasma generator releases broadband electromagnetic pulses for active electromagnetic interference. The segmented arc-shaped steel plate 122 serves as the second level of protection, further absorbing and dispersing energy. The steel-framed concrete dome 123 serves as the third level of protection, ensuring structural stability. The outer penetration-resistant plate 112 of the main structure 11 resists the penetration of the warhead, and the inner self-healing concrete 111 automatically repairs cracks after damage through microbial-induced mineralization repair technology.

[0082] S50: System self-sufficiency and recovery. The energy supply system 40 continues to operate, ensuring that the protection system can quickly recover its function after being attacked. The inner self-healing concrete 111 completes self-repair. The water protection system 20 and the land protection system 30 re-enter standby mode to maintain the bunker's long-term concealment and protection capabilities.

[0083] In summary, this invention designs a dual-protection system—internal and external—for island and reef bunkers against conventional weapon attacks. The energy supply system serves as the foundation, providing power for all active protection and intelligent functions. The land-sea protection system is the first line of defense, using active acoustic camouflage and multi-spectral jamming to reduce the probability of detection, identification, and precise hits, protecting the bunker from or mitigating the initial wave of attack. The bunker's composite biomimetic protection system is the second and core physical barrier. When active defense fails to completely evade attacks, its robust biomimetic outer layer, dome structure, and intelligent self-healing inner concrete layer ensure the bunker's structural integrity and functionality. These three parts—energy supply, early interference avoidance, damage protection, and intelligent repair—together constitute a comprehensive protection system integrating concealment, resilience, self-sufficiency, and self-healing, comprehensively enhancing the survivability and sustained combat capability of island and reef bunkers against conventional weapon attacks.
