Compared with the prior art, the invention has the beneficial effects that: the invention provides an underwater high-pressure air bubble bomb which has the action and efficiency similar to those of underwater explosion air bubbles, but the killing power is far smaller than that of the underwater high-pressure air bubble bomb, and can effectively deter and even stop a target ship under the condition of not damaging ship personnel. The bubble bomb has the characteristics of low use cost, stable performance, high automation degree, environment friendliness, marine organism friendliness and the like, so that the bubble bomb is non-lethal equipment capable of being used for warning and expelling.
Upon far field excitation: the load applied by the bubble bomb to the target ship is mainly shock waves, and the shock wave load can often cause elastoplastic deformation of the structure or excite the overall response of the structure, such as whip motion of the ship body, so that the overall strength of the ship body is endangered when the whip motion is serious under specific working conditions, and even the ship body can be broken directly. By adjusting the bubble intraelastic pressure and volume, the specified shock wave load can be accurately applied to the target ship, and the target ship can be effectively deterred and blocked while the target ship and personnel are not endangered.
Upon near field excitation: the shock wave and bubble dynamics effects can cause the structure to generate large plastic deformation and even dynamic fracture phenomena. Even if the energy of the air bubbles is controlled by adjusting the excitation parameters, the pulsation of the large-scale air bubbles and the water scale caused by the pulsation of the large-scale air bubbles can easily trigger the violent shaking of the small-tonnage ship, so that the normal work of personnel and equipment is greatly influenced, and the effective warning and deterrence are carried out.
When continuously excited: considering the progress of modern military technology, the firing speed of the warship can reach 1-2 times per second, and the gas released by the last bubble bomb still does not float to the water surface and is dissipated, and the next bubble bomb follows. By either out-of-phase pulsed bubble interactions or pulsed bubble interactions with normal pressure up-floating bubbles, continuously excited bubble bullets can provide more complex continuous impact on the target vessel, continually deterring and arresting the target vessel.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. It should be noted that, in the case of no conflict, embodiments of the present invention and features of the embodiments may be combined with each other, and the described embodiments are only some embodiments of the present invention, not all embodiments.
Referring to fig. 1 for an illustration of the present embodiment, the present example is capable of creating a water curtain and an underwater cavitation zone in front of a target vessel, thereby achieving the effect of deterring and interfering with vessel navigation. The underwater high-pressure gas bubble bomb adopts a cartridge case split charging structure, and comprises a bomb 7 and a bomb 11, wherein the bottom of the bomb 7 is clamped at the front end of the bomb 11, a trigger fuse 1, a delay fuse 3, an airtight partition 4, a detonator 5, an excitation explosive column 6, high-pressure gas 8 and a one-way inflation valve 9 are sequentially arranged in the bomb 7 along the axial direction, the trigger fuse 1 is arranged at the forefront end of the bomb 7 in the axial direction, the one-way inflation valve 9 is arranged at the axial bottom of the bomb 7, a safety steel ball 2 is arranged between the trigger fuse 1 and the delay fuse 3, the safety steel ball 2 is biased at a non-coaxial position between the trigger fuse 1 and the delay fuse 3, the detonator 5 is wrapped at the front end of the excitation explosive column 6, and the excitation explosive column 6 is wrapped by the high-pressure gas 8.
The inside joint groove, propellant powder 10, primer 12 and firing pin recess 13 that have set gradually along the axial of bullet section of thick bamboo 11, the joint of body 7 bottom is in the joint inslot, firing pin recess 13 runs through bullet section of thick bamboo 11 bottom. The propellant charge amount of the propellant 10 can be adjusted, and the charge amount can be flexibly changed according to the distance of the target during shooting so as to achieve the required initial speed, trajectory and range.
The pressure of the high pressure gas 8 is 500-3000Psi, and the term "high pressure" in the high pressure gas 8 and the underwater high pressure bubble bomb is defined by this pressure range.
The shell of the elastomer 7 adopts a streamline rotary structure configuration and is made of carbon fiber composite materials, the density is light, the strength is high, and the shell of the elastomer 7 is provided with prefabricated cracks so as to be convenient for rapid release of high-pressure gas 8. The shell of the projectile body 7 is pressed with the projectile belt, and the projectile belt is embedded into the rifling during the launching, so that the projectile body 7 rotates at a high speed after being launched, the stable flying of the projectile body 7 is ensured, and the energy utilization rate of the propellant powder 10 is high.
The triggering device is arranged at the front end inside the projectile body 7 and comprises a triggering fuse 1, a safety steel ball 2 and a delay fuse 3, wherein the triggering fuse 1 and the delay fuse 3 are of a revolving structure and coaxial with the projectile body 7, and the edges of the adjacent side end parts of the triggering fuse 1 and the delay fuse 3 are provided with inward fillets, so that a cavity with a section similar to a capsule shape is formed among the triggering fuse 1, the delay fuse 3 and the projectile body 7, and the safety steel ball 2 is positioned in the cavity, the radius of the cavity is slightly smaller than the width of the cavity and the length of the cavity.
The adjacent side end parts of the trigger fuse 1 or the delay fuse 3 have certain magnetism, and have certain adsorption capacity to the steel ball 2 made of stainless steel materials, so that the steel ball 2 can be always clamped between the trigger fuse 1 and the delay fuse 3 under the non-working states of production, transportation, storage and the like, and even if displacement occurs accidentally, the steel ball can be automatically corrected. The steel ball is blocked at the position of the firing pin in the safety state, and the projectile body 7 automatically rotates at high speed after the projectile is launched to enable the safety steel ball 2 to be automatically separated, so that the trigger fuse 1 is allowed to strike the delay fuse 3. Besides the time delay fuze 3, the bubble bomb can be flexibly triggered by a near-explosion fuze and the like, and has good adaptability to various possible conditions on the sea.
For the convenience of law enforcement personnel's operation, there is airtight wall 4 between detonator 5 and delay fuse 3, airtight wall 4 links to each other with projectile body 7 for projectile body 7 inner structure separates into front and back two parts, makes projectile body 7 can dismantle at airtight wall 4 the preceding head, allows operating personnel to carry out wired connection setting parameter to delay fuse 3. Besides the wired connection setting parameters, the time delay parameters of the bubble bomb can be set in a wireless connection mode.
Considering that the high pressure gas 8 is different from the former explosive material, detonation cannot be generated to open the projectile body 7, the projectile body 7 is provided with a detonator 5 and an excitation grain 6 behind the airtight partition 4 for actively opening the casing of the projectile body 7 and rapidly releasing the high pressure gas 8. The high-pressure gas 8 defaults to high-pressure air, but under the condition that greater deterrence is needed, the filling of high-pressure mixed gas consisting of oxygen and combustible gas can be considered, and the mixed gas deterrence is higher than the high-pressure air, but the deterence is still higher than that of explosive materials, and the safety is ensured. The pressure of the high-pressure air and the high-pressure mixed gas is also 500-3000Psi.
The bottom of the projectile body 7 is provided with a one-way inflation valve 9 with a high-strength self-locking valve cover and is coated with fireproof materials, so that the stability of the high-pressure gas 8 after the bubble projectile is excited is ensured not to be influenced by the deflagration of the propellant powder 10.
When in use, an operator injects high-pressure gas 8 to the specified pressure through the one-way inflation valve 9 according to the measurement and calculation of matched software and related experience before use, sets the delay time of the delay fuse 3, and then assembles the projectile body 7 and the projectile barrel 11 to finish the preparation for launching. When the gun bore is excited, the firing pin impacts the firing pin groove 13 at the bottom of the cartridge 11, ignites the primer 12 and further ignites the propellant powder 10, the high-temperature and high-pressure gas generated by combustion of the firing pin rapidly pushes out the projectile 7, and the projectile 7 is thrown out of the steel ball 2 due to the strong rotation of the projectile belt while flying out at a high speed. The projectile body 7 collides with the liquid level to trigger the fuse 1 to start the delay fuse 3, after the countdown of the delay fuse 3 is finished, the electric spark delay fuse 3 starts the detonator 5 and the excitation grain 6 to detonate and break the presplitting shell to release the high-pressure gas 8, so that high-pressure bubbles are rapidly generated at the appointed depth under water, and the target ship is deterred by shock waves, bubble pulsation and water surmounting.
When the bubble bomb is excited in the far field: the load applied by the bubble bomb to the target ship is mainly shock waves, and the shock wave load can often cause elastoplastic deformation of the structure or excite the overall response of the structure, such as whip motion of the ship body, so that the overall strength of the ship body is endangered when the whip motion is serious under specific working conditions, and even the ship body can be broken directly. By adjusting the bubble intraelastic pressure and volume, the specified shock wave load can be accurately applied to the target ship, and the target ship can be effectively deterred and blocked while the target ship and personnel are not endangered.
When the bubble bomb is excited in the near field: the shock wave and bubble dynamics effects can cause the structure to generate large plastic deformation and even dynamic fracture phenomena. Even if the energy of the air bubbles is controlled by adjusting the excitation parameters, the pulsation of the large-scale air bubbles and the water scale caused by the pulsation of the large-scale air bubbles can easily trigger the violent shaking of the small-tonnage ship, so that the normal work of personnel and equipment is greatly influenced, and the effective warning and deterrence are carried out.
When the bubble bomb is continuously excited: considering the progress of modern military technology, the firing speed of the warship can reach 1-2 times per second, and the gas released by the last bubble bomb still does not float to the water surface and is dissipated, and the next bubble bomb follows. By either out-of-phase pulsed bubble interactions or pulsed bubble interactions with normal pressure up-floating bubbles, continuously excited bubble bullets can provide more complex continuous impact on the target vessel, continually deterring and arresting the target vessel.
The embodiments of the invention disclosed above are intended only to help illustrate the invention. The examples are not intended to be exhaustive or to limit the invention to the precise forms disclosed. Many modifications and variations are possible in light of the above teaching. The embodiments were chosen and described in order to best explain the principles of the invention and the practical application, to thereby enable others skilled in the art to best understand and utilize the invention.
