2. use the method for deep-sea simulation acoustics experiment table as described as right 1, it is characterized in that the method comprises that water tank assembling, pressure regulation pressurize, bubble occur, four parts of acoustic sounding, concrete steps are as follows:
A, water tank assembling process:
Before A-1 starts assembling, according to requirement of experiment, at the good related experiment equipment of water tank internal placement; Again the aerator (205) in bubble generation systems (02) and sound system (05) are installed, the interface between pressure regulation pressure-retaining system (03), tank pressure protection system (04) and cistern system (01) is installed simultaneously; Then by automatic open device (105), tank lid (108) is closed, guarantee to seal zero-clearance by O-ring seal (102) between tank lid (108) and water tank (109), and by locking hoop (103) by both bandings, guarantee under water tank (01) high pressure conditions all the time in sealing state; Wherein thermometer (106) is as the embedded parts of tank lid (108), and pressure compensator (107) is as the embedded parts of water tank (109), and both, start working while closing in tank lid (108); Whole assembling process completes on support stand (104);
A-2, after experimental implementation, after reducing to normal pressure in water tank (01), can open water tank (01) by automatic open device (105) automatically;
B, pressure regulation pressure maintaining period:
Before the B-1 pressure regulation, air abrim in cistern system (01), pressure is atmospheric pressure, and the valve of pressurize T-valve (211) is in open mode, and other all valves are all in closure state;
During the B-2 pressurization, the spool of opening between front pressure regulation two-port valve (202), voltage-regulation voltage-stabilization valve (204), rear pressure regulation two-port valve (210) and pressure regulation T-valve (209) left side import and right side outlet (opens left side import and right side outlet, the upside port closing), produce source of the gas by the first gas compressor (201), liquid in simulated seawater case (203) is clamp-oned in cistern system (01), when pressurize T-valve (211) just has solid stream of water to flow out, close front pressure regulation two-port valve (202), the first gas compressor (201) quits work simultaneously, all valves in pressure regulation pressure-retaining system (02) are all closed, now, keep pressure regulation T-valve (209) left side import and right side outlet to open, upper side outlet is still closed, locate to set at pressure regulation tensimeter (208) pressure values that water tank (01) will reach according to requirement of experiment, and open liquid booster pump two-port valve (207) and rear pressure regulation two-port valve (210), controlling liquid booster pump (206) by the first controller (214) starts working, constantly feed-tank (01) supercharging, when reaching requirement of experiment pressure, the left side import of pressure regulation T-valve (209) is closed immediately, upper side outlet is opened, the first controller (214) is given an order simultaneously, liquid booster pump (206) quits work, now pressure regulation tensimeter (208) is located Real-Time Monitoring and is shown the pressure of water tank (01), if change, the upper side outlet of pressure regulation T-valve (209) is closed immediately, the left side import is opened, the first controller (214) start liquid supercharge pump (206) feed-tank (01) supercharging immediately, when water tank reaches designated value, quit work, pressure regulation T-valve (209) also recovers the left side import and closes, the state that right side and upper side outlet are opened, so go round and begin again, thereby reach the function of pressurize, the data that dwell pressure table (212) is located to show are the pressure at water tank (01) top, as the standby parameter of experiment,
During the B-3 pressure release, when the experiment link in certain pressure finishes, need pressure release, now make liquid booster pump (206) and the first controller (214) quit work, close all valves, only rear pressure regulation two-port valve (210) and blowdown valve (215) are opened, the liquid in water tank (01) enters simulated seawater case (203), recovers normal pressure in water tank (01); And then open backflow two-port valve (213), and produce source of the gas by the first gas compressor (201), remaining liquid in water tank (01) is all entered in simulated seawater case (203);
During the B-4 pressure regulation, in the B-2 step, after pressurization, if will realize, the pressure in water tank (01) is larger than existing pressure, by the first controller (214) and liquid booster pump (206), on the basis of B-2 step, is continued to be pressurized to and specifies pressure to get final product; If realize, the pressure in water tank (01) is less than existing pressure, and with reference to the B-3 step, each valve all is arranged on the state of B-3 step, and sets one at blowdown valve (215) and specify pressure values, starts pressure release; In water tank (01), reach while specifying pressure, each valve returns to the state of B-2 step, and, by the first controller (214) and liquid booster pump (206) acting in conjunction, realizes pressurize;
In the B-5 experimentation, in water tank (01), pressure is very large, exists certain danger, and for guaranteeing experiment safety, tank pressure protection system (04) plays very important effect; When in water tank (01), pressure surpasses certain safety value, second controller (401) is given an order, and under the action of gas source of the 3rd gas compressor (406), pneumatic valve (403) is opened, and is water tank (01) pressure release, thereby reaches the effect of protection; , when explosion-proof valve (404) water tank (01) reaches capacity pressure, automatically open, be water tank (01) pressure release simultaneously;
C, bubble generating process:
After above-mentioned steps is equal, water tank (01) is in simulation deep-sea state, be pressed into gas by the second gas compressor (306), and under the acting in conjunction of throttling valve (304), pressure maintaining valve (303), flowmeter (302), tensimeter (301) and aerator (305), the bubble that generation physics, chemistry can arrange; Wherein by the second gas compressor (306), be pressed into the chemical composition difference of gas, can control the chemical composition of produced bubble; By adjusting the size of aeration board small aperture in aerator, can control the size of bubble; By the quantity of aeration board aperture and the flow of gas in the adjustment aerator, can control quantity and the speed of Bubble formation;
D, acoustic sounding process:
Bubble to be generated, after the requirement of experiment state, is sent the signal of experiment predeterminated frequency by signal generator (503), after adjusting by power amplifier (502), signal is inputted to ultrasonic probe (501), sends ultrasound wave; After ultrasound wave runs into the object such as bubble, sound wave will be reflected, and to return in certain path, by ultrasonic probe (501), be received, and finally by data acquisition system (DAS) (504), carry out the data analysis processing, draw the mechanism of acoustic sounding deep sea deposits.
