Problems solved by technology

[0002] In recent years, with the increase in the number of underwater engineering constructions, it has been a difficult problem for technicians to overcome the research and development of underwater engineering targets to prevent them from being impacted by explosion shock waves; due to the small compressibility of water, the explosion shock waves generated by explosives exploded underwater , has the characteristics of high peak pressure, high impulse, and high destructiveness; this poses a great threat to underwater engineering targets
[0003] In the prior art, there is no good method for the protection of underwater engineering targets to resist the impact of the explosion shock wave; when the explosive explodes underwater, detonation occurs from the starting point of the explosion, and a large amount of energy is released, forming a high temperature The high-pressure explosion product, and then the explosion energy vaporizes the nearby water in the form of radiation heating to form a high-temperature and high-pressure water vapor ball, which triggers the generation of shock waves; the pressure wave generated after the water explosion travels outward from the center of the explosion in the form of spherical waves Rapid propagation, there are two forms of damage to underwater protection targets, one is the shock wave, which destroys the target with the powerful overpressure generated at the moment of the explosion; the other is the bubble pulsation pressure wave generated after the explosion, which affects the underwater protection Destroy the target
At present, for underwater protection targets, there is no method for resisting the impact force of the explosion shock wave; the invention is based on the problems in the prior art, and a wave suppression device for preventing underwater engineering targets from being impacted by the explosion shock wave has been developed, which can be very good effectively solve the technical problems existing in the existing technology

Abstract

The invention discloses a wave absorbing device for preventing an underwater engineering target from being impacted by explosion shock waves. The device is characterized in that hollow pipes are vertically and fixedly arranged in parallel, and the hollow pipes are fully distributed on a left wall surface, a right wall surface, a front wall surface and a rear wall surface; the upper parts of the hollow pipes are fixedly connected to a vent pipe, the lower parts of the hollow pipes are closed, hollow pipe exhaust holes are uniformly and fixedly arranged on each hollow pipe, and hollow sphericalshells are arranged on the hollow pipe exhaust holes of the hollow pipes; pressure sensors are correspondingly arranged on the left wall surface, the right wall surface, the front wall surface and therear wall surface; an automatic control device is fixedly arranged at the upper left position of an air blower above water surface, and a control switch is fixedly arranged in the automatic control device; and one end of an air inlet pipe is fixedly connected to the vent pipe, and the other end of the air inlet pipe is fixedly connected to the air blower. According to the wave absorbing device for preventing the underwater engineering target from being impacted by the explosion shock waves, the impact damage of the explosion shock waves to the underwater protection target is greatly reduced,and the impact force of the explosion shock waves is weakened.
