Pin is inserted perpendicularly into sedimentary, freezes and gathers sample.
What the alignment system reception wireless signal transmitting device and underwater camera set in automatic control platform was passed back in real time
Image, data.
The excitation apparatus of gravity drop hammer in sampler is controlled by automatic control platform.
Adjust support of the support by three adjustment lengths, and the balance adjusting device composition between support.
Also include the wireless signal transmitting device and underwater camera above balance adjusting device, alignment system receives
Image that wireless signal transmitting device and underwater camera are passed back in real time, data.
The application method of vertical freezing sampling apparatus, comprises the following steps：
(1) operation ship is opened to needing at sampling, control sampler makes it be slowly dropped to river bed；
(2) the data point reuse sampler position passed back in real time by wireless signal transmitting device and underwater camera；
(3) after determining sampler position, by automatic level leveling system control adjustment support, make copper pipe probe perpendicular to
Sedimentary；
(4) gravity drop hammer is excited, copper pipe probe is inserted perpendicularly into sedimentary；
(5) valve is opened, makes liquid CO2Pass through CO2Intake pipeline enters in copper pipe probe, liquid CO2Vaporization heat absorption, copper
Deposit around pipe probe is rapidly freezed, caused CO2Gas is by CO2Export pipeline is discharged；
(6) when the data that temperature sensor is passed back reach stable state, lifting system is controlled, sampler is proposed, taken
Lower copper pipe probe and sample；
(7) hot water is poured into copper pipe probe, makes sample and copper pipe probe separates, sample is loaded into sample box, and be put into
In refrigerator.
Beneficial effect：Compared with prior art, the present invention has advantages below：(1) deepwater regions column is can be not only used for sink
The in-situ acquisition of product thing, directly it can also will be equipped with liquid CO2The sampler of feeding mechanism is used for the original of shallow water area deposit
Position collection, and ensure that the sampling success rate of equipment under high flow velocities；(2) minimize the biochemical activity in sample,
It ensure that the reset condition of sample；(3) destruction of the sampler to the composition of sample, and river are reduced to the shadow of sample constituents
Ring.
