It can be built-in with the steel disc (not shown) of multi-disc lotus petal shape in the edge of a knife 4, be inserted into seabed in the edge of a knife 4
Before deposit, the steel disc of lotus petal shape is in horizontal closed state；When into the soil body, the steel disc of lotus petal shape is sunk by seabed
Product object squeezes, and bottom sediment is enable to can smoothly enter into；When the edge of a knife 4 is proposed from bottom sediment, the steel of lotus petal shape
Piece restores horizontal closed state again, achievees the purpose that being closed the edge of a knife 4 prevents collected bottom sediment sample from leaking.
Below with reference to Fig. 1-Fig. 3, the working principle of the acquisition device of the present embodiment is described below:
After arriving at the placement in sea area to be measured using scientific investigation shipping load acquisition device, acquisition dress is sling using boat-carrying wirerope
Mentioning for setting first 10 is transferred to sea, and control detacher is detached from, and is launched acquisition device and is entered sea.
Acquisition device sinks under the gravity of itself and clump weight 8 after entering sea, and when reaching seabed, the edge of a knife 4 penetrates sea
Bottom sediment makes 1 injection of probe tube into bottom sediment.
In probe tube 1 to during bottom sediment injection, when probe tube 1 reaches certain depth of penetration, frame
Formula pedestal 21 is located on sea bed, and the injection posture of adjustment probe tube 1 makes it perpendicular to bottom sediment surface layer.If probe tube 1
Continue injection, then framework type base 21 is moved up relative to probe tube 1, close to clump weight 8.When moved on in framework type base 21 with
Clump weight 8 adjacent to when, the damping spring 28 for being mounted on the lower section of clump weight 8 is resisted against on the retaining ring 25 of 24 top surface of round tube, to sampling
The penetrating power of pipe 1 carries out buffering until stopping injection, then plays the role of limiting 1 depth of penetration of probe tube.
After probe tube 1 is smoothly erected on bottom sediment, hawser 11 is pulled up, control piston 3 is moved up until contact
Stop after to baffle 5.At this point, generating negative pressure in plastic bushing 2, bottom sediment is forced to enter plastic sheath under the action of negative pressure
Pipe 2 realizes column sampling.
During acquiring bottom sediment sample, two pieces of bottom plates 16,17 in automatic open-close component 13 are in ocean bottom
It is flipped up under the pressure of water, opens through-hole, be circulated into Bottom Water in Ocean in water tank 6 by through-hole, realized to ocean bottom
The sampling of layer water.
After sampling, acquisition device is recycled by pull-up hawser 11.During acquisition device rises, automatic open-close
Two pieces of bottom plates 16,17 in component 13 are downwardly turned over by the water currents in water tank 6, until two pieces of bottom plates 16,17 quilts
Retaining bolt 18 stops and stops operating.At this point, two pieces of bottom plates 16,17 mutual splits and with the sealing ring of through-hole edge 15 closely paste
It closes, it is thus achieved that the closure to through-hole, enables collected Bottom Water in Ocean to seal up for safekeeping in water tank 6.
After acquisition device salvages disembarkation, acquisition device is laid flat, selects position water valve 19 directed downwardly to open, will protect
There are the Bottom Water in Ocean samples in water tank 6 to be transferred in suitable test chamber.By push piston 3 under foreign object, will save
It is transferred in suitable vessel in the bottom sediment sample in plastic bushing 2, for laboratory research in the future.
The double synchronous acquisition tasks to bottom sediment and Bottom Water in Ocean are just completed as a result, save sampling
Time and cost of labor.
The present embodiment adds framework type base 21 on probe tube 1, and probe tube 1 can be made to be perpendicularly inserted into sea bed, with
The success rate for guaranteeing Seafloor sediment sampling, overcomes influence of the deep-sea ocean current to sampling apparatus.By in the lower part of clump weight 8
Damping spring 28 is added, can reduce the inertia force of probe tube 1, controls maximum depth selection, and probe tube 1 and frame can be reduced
The impact force of formula pedestal 21, the problems such as avoiding clump weight 8 from penetrating water sample resulted in sea bed muddy, water degradation, go out
It is existing, effectively ensure the sampling quality of Bottom Water in Ocean.
Certainly, the above is only a kind of preferred embodiment of the utility model, it is noted that for the art
Those of ordinary skill for, without departing from the principle of this utility model, several improvements and modifications can also be made, this
A little improvements and modifications also should be regarded as the protection scope of the utility model.
