Connection between above-mentioned each parts all links to each other by underwater electrical connector.
The principle of work of in-situ detecting system that is applicable to elevated temperature heat liquid zone, deep-sea is as follows:
Total system work has three states, is respectively acquisition mode, flushing state, demarcation state.Elaborate below in conjunction with the principle of work of duty to system.
During acquisition mode, microcontroller 17 control step motors 26 drive screw rod 25 and rotate with certain speed, so drive slide block 23 shift positions, when wire rope 22 traction probes 32 change position to top cylinder through holes 5 connect with housing 1 through through hole 31 (as shown in Figure 1), stepper motor 26 just stops operating, owing to have self-locking performance between screw rod 25 and the slide block 23, probe 32 just can be still in position shown in Figure 1.This moment, the popped one's head in outer wall of lower cavity of water delivering orifice of flushing-liquid pipe 10 blocked, and the water inlet pipe 30 and the flushing-liquid pipe 10 of hydrothermal solution sampling sniffer are not communicated with.Because hydrothermal vent is constantly to the external eruption hydrothermal solution, hydrothermal solution enters top cylinder through hole 5 through filter mantle 6 and contacts with exploring electrode 4.Exploring electrode produces certain electric signal according to the difference of contained chemistry amount in the hydrothermal solution, and microcontroller 17 receives electric signal and just signal is further processed, such as computing, storage etc.Hydrothermal solution in this moment top cylinder through hole 5 mainly relies on hydrothermal solution to erupt to upgrade voluntarily.
Flushing and demarcation state: 26 rotations of microcontroller 17 control step motors, make probe 32 change position to top cylinder through hole 5 and leave the through through hole 31 of housing, and when aperture 7 on the housing links to each other, as shown in Figure 2, this moment, top cylinder through hole 5 and extraneous seawater were communicated with, the water delivering orifice alignment of the water inlet of water inlet pipe 30 and flushing-liquid pipe 10 is so water inlet pipe 30 and flushing-liquid pipe 10 are communicated with.
1) flushing process: microcontroller 17 sends instruction, pump 13-2 operation, and the first solenoid valve 13-1 opens, from extraneous extracting seawater.Seawater enters into probe top cylinder through hole 5 along washing fluid water inlet pipe 10 and water inlet pipe 30, discharge from aperture 7, flushing exploring electrode 4, fundamental purpose is some impurity that wash accumulation on the exploring electrode 4, thereby prevents that exploring electrode 4 from can not contact the detection effect that do not have with hydrothermal solution.Arrive when the time of setting, flow control system just cuts off the power supply and quits work.
2) demarcation state.Microcontroller 17 sends instruction, pump 13-2 operation, and the second solenoid valve 13-3 opens, from titer leather bag 16 draw standard liquid.Titer enters into probe top cylinder through hole 5 along washing fluid water inlet pipe 10 and water inlet pipe 30, discharge from aperture 7, exploring electrode 4 can be immersed in the titer in this process, thereby plays the demarcation effect, and the main effect of demarcation is to make exploring electrode 4 recover detection performance.Thereby prolongation mission life.
After total system was put into elevated temperature heat liquid zone, deep-sea by latent device, system just entered acquisition mode, and after detection after a while, exploring electrode is malfunctioning, and system just enters into flushing and the demarcation state is safeguarded exploring electrode.When flushing of exploring electrode process and demarcation, return to normal operating conditions, system enters into acquisition mode again.The continuous periodic duty of system like this guarantees that exploring electrode can long-term stable operation.
