Background technology
Along with the development of blasting technique, the Underwater Engineering explosion is used for explosion reef, dredging channel, excavation hydraulic structure foundation ditch, excavation canal, water-bed pipeline, underwater demolition compacting more and more widely and the petroleum works deep-sea is exploited demolition blasting of back discarded object or the like.
The Underwater Engineering explosion was meant at the utmost point in the short time, and the process of very big power conversion takes place in the underwater limited bulk.Underwater demolition can be divided into three phases substantially: the formation and the pulsation of the detonation of explosive, the generation of shock wave and propagation, bubble.Explosive is explosion output energy different along with explosive surrounding medium and environment under water, and the energy of output is also different; Act on the difference of energy on the explosion matter body, demolition effect is also different.Underwater demolition also comprises a lot of uncertain factors, as the explosive type of underwater demolition, dose size, explosive to the distance of works, underwater environment or the like, more than all these characteristics make the research of underwater demolition problem become quite complicated and difficult.
For this reason, the research of carrying out the Underwater Engineering blasting technique has caused relevant scientific and technical personnel's attention, though the analogue experiment installation of underwater demolition comes out, lower with the similarity of actual environment, the experimental provision that especially can simulate deepwater environment under the moving water state does not appear in the newspapers.
Summary of the invention
Task of the present invention provide a kind of reasonable in design, easily manufactured, with the moving water state of the high simulation of actual environment similarity under 200 meter level deep water explosion experimental provisions, with impact wave energy, bubble energy and the gross energy parameter that records powder charge.
For realizing above-mentioned task, the technical solution adopted in the present invention is: the hollow spherical tank that this device is made for the A3 steel, internal diameter are 1500～2500mm, and wall thickness is 5～15mm; The bottom of hollow spherical tank is fixed on the base support.
Be provided with two observation windows on the tank body of hollow spherical tank symmetrically, the line of centres of two observation windows passes the center of tank body, and the diameter of observation window is 200～400mm, and observation window all is equipped with lucite.
The top of hollow spherical tank has working hole, and working hole is equipped with mounting cover, and mounting cover is provided with three and penetrates hole and a high-pressure air pipe joint, and three penetrate the hole and the high-pressure air pipe joint is all used flange seal; The bottom of hollow spherical tank is provided with water pipe head.
The lead-in wire that connects explosive passes three holes that penetrate in the hole; Pressure sensor is hung a side in hollow spherical tank by suspension hook, and the waterproof shielded cable that connects pressure sensor passes three another holes that penetrate in the hole, and the waterproof shielded cable is connected with data collecting instrument; Electric mixer is installed on the bottom interior wall of hollow spherical tank, and the lead that connects electric mixer passes three the 3rd holes that penetrate in the hole, connects the lead external power supply control device of electric mixer.
Described lucite thickness is 100～200mm, is provided with rubber washer between lucite and hollow spherical tank, and the thickness of rubber washer is 2～4mm; Three diameters that penetrate the hole are 5～8mm; The maximum working pressure (MWP) of hollow spherical tank (6) is 2.5MPa.
Because adopt technique scheme, the present invention has installed electric mixer in hollow spherical tank, produce the current of adjustable-speed by electric mixer, thereby simulate moving water state.Under the situation that the static pressure of water remains unchanged, apply certain gases at high pressure for the water in the hollow spherical tank by high-pressure pipe connector, add air pressure changing the pressure that cartridge bag was born in the water by what change the hydrostatic surface, thereby simulate the pressure environment that the different depth of water produces.
This analogue means sensor installation and carry out the collection of signal by tester in hollow spherical tank.Explosive is under water after the explosion, in water, produce shock wave and bubble pulsating wave, utilization places burst pressure sensor test under water to go out this two time dependent courses of ripple, through signals collecting, conversion, amplification, analysis and computing, can obtain impact wave energy, bubble energy and the gross energy parameter of powder charge.
Therefore, the present invention is by impressed pressure, makes maximum working pressure (MWP) in the hollow spherical tank to 2.5MPa, can simulate the deepwater environment of 200 meter levels, and produces the current of adjustable-speed, the moving water state of simulation by electric mixer.So this analogue means can be used for simulating the deep water explosion experimental study of 200 meter levels under the moving water state, has characteristics reasonable in design, easily manufactured and high with the actual environment similarity.
