It is an indispensable part of the national sustainable development strategy and has great significance in maintaining national defense security. In order to ensure marine security, it is necessary to quickly deploy gas-producing materials over a long distance in a certain sea area to achieve the goal of protecting marine structures, such as carrying materials such as lithium hydrogen to create bubble curtains to protect underwater structures. Therefore, the bubble curtain needs to be able to reach the specified thickness and diffusion range in a short time, which puts forward requirements for the transportation and diffusion of gas-producing materials over a long distance and a large range.

For the goal of long-distance scattering, a more powerful device is needed to meet the requirements; if underwater navigation is used for scattering, the economic cost is high and the possibility of underwater interference is high. Therefore, how to achieve fast, efficient, and low-cost underwater long-distance scattering is an important issue in ship protection. Summary of the invention

DETAILED DESCRIPTION

[0027] The specific implementation of the present invention is further described in detail below with reference to the accompanying drawings:

[0028] Specific implementation method 1: See Figure 1-Figure 7The present embodiment is specifically described. The underwater long-distance gas-producing material dispersion device based on energetic materials described in the present embodiment specifically includes a guide part 1, a delivery part 2 and a power propulsion part 4, which are connected in sequence; a navigation device is arranged in the guide part 1; a trigger 6, energetic materials 7, a plurality of launch tubes 15 and a plurality of material delivery projectiles are arranged in the delivery part 2, and a material delivery projectile is arranged in the launch tube 15; a thin shell 3 is arranged at the upper end of the launch tube 15, and the lower end is connected to the inside of the delivery part 2; the energetic material 7 is arranged at the bottom of the launch tube 15 and the material delivery projectile, and surrounds the bottom of the material delivery projectile, and provides sufficient thrust to the material delivery projectile when the energetic material 7 is excited; the thin shell 3 is made of ceramic, and the material delivery projectile breaks through the thin shell 3 under the action of the energy released by the energetic material 7, and is thus launched to the outside. The outer surface of the thin shell 3 is flush with the outer surface of the delivery part 2, and a drag-reducing coating is coated on the outer surface of the thin shell 3, so that the autonomous underwater vehicle maintains a good resistance characteristic; the navigation device is connected to the trigger 6; the trigger 6 is in contact with the energetic material 7, and the energetic material 7 is stimulated by the trigger 6; and a gas-generating material 9 is arranged inside the material delivery bomb.

[0029] The guide part 1 is provided with a sonar detection system 5, through which navigation is performed. The sonar detection system 5 is connected to a trigger 6. After receiving a signal from the sonar detection system 5, the trigger 6 excites the surrounding energetic materials 7, and uses the energy released by the energetic materials 7 to push the material delivery projectile out.

[0030] The material delivery projectile comprises a head shell 8, a parallel middle body 10, a hemispherical protective shell 11 and a material storage part 13, wherein the head shell 8 and the material storage part 13 are connected, and there is no fixed connection between the hemispherical protective shell 11 and the head shell 8, and between the hemispherical protective shell 11 and the material storage part 13; the material storage part 13 is a hollow hemispherical structure, and a gas-generating material 9 is arranged inside the hemispherical surface of the material storage part 13; a plurality of straight slot holes 12 are arranged on the hemispherical surface of the material storage part 13, the first part of the straight slot holes 12 are at a distance of 1 / 3 of the radius from the center of the hemispherical surface, and 6 straight slot holes are evenly distributed along the axial direction; the second part of the straight slot holes are at a distance of 2 / 3 radius, 4 straight slots 12 are evenly distributed along the axial direction; the lower end of the parallel middle body 10 is connected to the hemispherical protective shell 11, and is buckled on the outside of the material storage part 13, and the upper end of the parallel middle body 10 is in contact with the head shell 8; the parallel middle body 10 is a ring structure, and the material delivery projectile slides in the launch tube 15 through the parallel middle body 10 during the ejection process to ensure that the overall posture does not deflect, and the material delivery projectile as a whole always moves along the axial direction of the launch tube; the material storage part 13 is made of fluororubber, which has good ductility and good chemical corrosion resistance, and the elongation at break can reach 150% to 350%. The hemispherical protective shell 11 is made of heat-insulating material, which can transfer momentum and has the function of hindering heat conduction to prevent the fluororubber and the carried gas-generating material 9 from changing their physical and chemical properties due to high temperature.

[0031] The launch tube 15 is provided with an annular blocker 14, and the material delivery projectile is arranged in the launch tube 15 at a position corresponding to the position below the annular blocker 14; the head shell 8 is semi-ellipsoidal, which ensures that the material delivery projectile has a small resistance coefficient under high-speed movement; the inner diameter of the annular blocker 14 is larger than the long axis of the head shell 8 and smaller than the outer diameter of the parallel middle body 10. The annular blocker 14 can block the movement of the hemispherical protective shell 11 and the parallel middle body 10 while ensuring that the semi-ellipsoidal head shell 8 and the material storage part 13 pass smoothly.

[0032] The surface of the thin shell 3 is an arc surface and is flush with the outer surface of the delivery part 2 shell, so that the delivery part 2 has an overall cylindrical structure; the thin shell 3 is made of ceramic, and a number of cracks are arranged on the inner surface of the thin shell 3, and inclusions are added in the inner center, so that the inner center is a brittle area, ensuring that the thin shell 3 can be smoothly broken under the impact of the head shell 8 without affecting the movement of the material delivery projectile.

[0033] The specific working process of the underwater long-distance gas-producing material dispersion device based on energetic materials described in the present invention is as follows:

[0034] After the autonomous underwater vehicle is launched, it navigates through the sonar detection system 5; after arriving at the predetermined position, the energetic material 7 is triggered by the trigger 6 according to the signal received by the sonar detection system 5; under the action of the energy released by the energetic material 7, the hemispherical protective shell 11 pushes the head shell 8 and the material storage part 13 and starts to accelerate; the head shell 8 moves outward and collides with the thin shell 3, and the head shell 8 smashes the thin shell 3 while the parallel middle body 10 and the annular blocker 14 come into contact; under the action of the annular blocker 14, the parallel middle body 10 and the hemispherical protective shell 11 are detached from the material delivery projectile and are left in the launch tube 15; the head shell 8 and the material storage part 13 carry the gas-generating material 9 and are ejected from the launch tube 15, and the gas-generating material 9 carried inside is dispersed from the straight slot hole 12. When carrying gas-producing materials 9 such as lithium hydrogen, water can directly enter the material storage part 13 from the straight slot hole 12 to react with the gas-producing material such as lithium hydrogen and produce hydrogen. The material storage part 13 expands under the action of gas pressure and causes the straight slot hole 12 to expand, so that the gas-producing material such as lithium hydrogen can further diffuse and react, so that bubbles are generated along the movement trajectory of the material delivery projectile and a bubble curtain is formed to protect the target object.

[0035] To summarize the above implementation cases, the underwater long-distance gas-producing material scattering device based on energetic materials described in the present invention overcomes the problems of limited transportation distance, high cost and high possibility of underwater interference in existing scattering methods, and uses an autonomous underwater vehicle as a transportation carrier of the gas-producing material 9, covers the launch port with ceramics, and uses the energetic material 7 as the power source of the material delivery projectile; the underwater long-distance gas-producing material scattering device based on energetic materials described in the present invention, under the action of energy released by the energetic material 7, cooperates with the material delivery projectile and the annular inhibitor 14 to decelerate the hemispherical protective shell 11, so that the gas-producing material can be smoothly diffused after being ejected from the outer shell of the autonomous underwater vehicle, thereby realizing directional and efficient transportation; the underwater long-distance target scattering device based on energetic materials described in the present invention can increase the amount of material scattered by a single autonomous underwater vehicle by changing the spacing between the launch tubes 15 (increasing the number of launch tubes 15), thereby realizing large-scale group diffusion.

[0036] The specific embodiments described above further illustrate the purpose, technical solutions and beneficial effects of the present invention. It should be understood that the above description is only a specific embodiment of the present invention and is not intended to limit the invention. It can also be a reasonable combination of the features recorded in the above implementation methods.
