Mutually combination.
As shown in figure 1, the present invention relates to a kind of marine monitoring sensor dynamic characteristic test platform, the platform includes water
Groove, TNE UPPER SEA TEMPERATURE control system, lower floor's water temperature control system, sensor motion Lift-on/Lift-off System, the portion such as spring layer interface camera system
Point.
Tank cell body 1 is the cylinder of 4.7 meters of depth, 91.4 centimetres of diameter, 2.54 centimetres of wall thickness, and material is titanium.
It is the workbench on one 3.6 meters above ground level of 2.5 meter of * 2.5 rice glue plywood deck at the top of tank.There is a metal building
Ladder and trapdoor.Tank/stage apparatus can be moved by heavy forklift when water tank is sky.
Sink body be divided into above and below two regions, top is A areas, and bottom is B areas, based on double diffusion principle, and lower floor's injection is warm
Seawater 2, upper strata injects cold fresh water 3, and the injecting process is as follows:
First, the direct water filling of external running water pipe, when water level reaches a fixing limit, stops water filling, is subsequently poured into progress
The salt for calculating out, stirs, and obtains lower floor's salt solution；, can be in lower floor's water for more careful differentiation levels water body
A certain amount of red ink is poured into body, color is added and distinguishes；It should be noted when upper water is injected, it is impossible to which external water pipe is straight
Water filling is connect, destruction lower floor water body very big with the decline potential energy of waterproof at this moment, spreads one layer of sponge, so in lower floor's water body upper surface
External water pipe is inserted into inside sponge afterwards, very small current are opened, to ensure not causing very in the interface of two layers of water body
Big mixing, with the injection of current, the water surface is slowly raised, and sponge is also slowly risen, now, it is clear that red
The boundary layer of salt solution and the fresh water of upper strata Transparent color；After upper strata fresh water depth reaches 50cm, sponge can be removed substantially, will be noted
Water pipe is along cell wall slowly water filling, also for the impact and destruction reduced to water body interface, at this point it is possible to which current are opened greatly
Point, is advisable with not destroying interface, and when fresh water injection reaches certain depth, whole water body the injecting process is completed.
All respectively there is a set of temperature control system in the lower regions of tank cell body 1, for accurate adjustment upper and lower region as needed
The water temperature in domain.

Come cold to upper water system, circulating chilled water realized by a laboratory refrigerator, the foam played at water termination suspension and
The effect of insulation.
It is placed with the thermohaline sensor 11 and 14 for monitoring each water layer, the thermohaline sensor respectively at the middle part of water layer up and down
For RDI temperature, conductivity probe, A, B area's water temperature and electrical conductivity are monitored for real-time, for confirming whether water body meets survey
Strip part.One of effect of thermohaline sensor is the temperature creep stress value for monitoring water body levels, helps to carry out the bar of judgment experiment
Whether part is ripe, and double diffusion is mainly based upon after more than one particular value of the density contrast of levels water body, and levels water body can be each
Self-loopa, it is ensured that the thermal field of respective water body and saltern are gradually uniform, and violent small turbulent motion occurs in spring layer interface,
Progressively it is formed in minimum thickness, thermograde and salinity gradient are very big, forms one layer of natural isolation barrier.
Compared to horizontal thermohaline tank before, mainly completely cut off two different thermal fields using middle insertion dividing plate come artificial
And saltern, it is the problem of a maximum of this method, with the increase of experiment number, the frequent opening and closing of dividing plate, pole
The mixing of left and right water body is easily caused, causes water body to reach that the uniform required time is longer again, test number (TN) is also limited.More cause
Life, the frequent opening and closing of dividing plate also easily bring failure in itself, and, if once dividing plate is not opened timely,
It is very easy to cause sensor impact, great test is brought to the safe design of whole system, many wind are also increased
Danger.And thermohaline spring layer tank uses rising structure, according to specific double diffusion physical phenomenon, naturally formed in water body intermediate layer
Thermograde and salinity gradient all unusual huge spring layers, are especially suitable for carrying out sensor dynamic characteristic research.
The temperature control system, come real-time response order, is to open heating or open refrigeration according to temperature monitoring apparatus
System, to ensure each layer thermal field uniformity at 0.1 DEG C.

Sensing station detecting system.Lift-on/Lift-off System may insure that sensor to be measured is moved according to the lowering velocity of setting.Sensor
Decrease speed is controlled motor 6 to be connected to belt pulley 7 to be controlled by speed regulator 5.Control small volume, weight can be realized
Light sensor speed is 1cm/s~270cm/s.
Sensor 9 to be measured and to place its towed body 8 be counterbalance design so that sensor 9 to be measured has free-falling
Terminal velocity, it is moderately more than required test speed.
Guide pillar 24 is disposed at the internal edge of tank cell body 1, sensor to be measured can be made most when up and down motion
Amount reduces the destruction to spring layer interface, and the towing cable of motion is limited in its space by guide pillar, is greatly reduced towing cable motion
Caused destruction and disturbance to interface so that interface is able to maintain that the longer time, is available for experiment number to increase.
The bottom of tank cell body 1 is additionally provided with the spring of coiling, it is to avoid instrument lowering velocity is too fast, and bottom is caused brokenly
It is bad.
At the middle part of tank cell body 1, spring layer observation window 19 is provided with, the position of spring layer is determined by spring layer interface camera system
Put and spring layer thickness.By analyzing images, position and the thickness of spring layer are drawn, sensor characteristics is analyzed
