TECHNICAL FIELD

[0001] The utility model relates to the technical field of protective engineering, and specifically to a protective engineering device with shock wave prevention function. BACKGROUND

[0002] Shock wave is a discontinuous peak propagating in medium, and this peak leads to the jump change of the physical properties such as pressure, temperature and density of the medium. This wave form will be generated when the movement speed of any wave source exceeds the propagation speed of its wave, and it is also called shock wave. The shock wave has a jump change of wave front, that is, a shock front is generated, and the physical properties of the medium at the shock front jump, and this sudden change will cause strong destructive effect on the surrounding environment. The propagation of shock wave is usually through the medium of matter such as air, water or solid matter. In nature, natural phenomena such as lightning, volcanic eruption or earthquake can generate shock wave. In human environment, explosion, flight of supersonic aircraft and the like can also generate shock wave.
