It connects;Connecting cylinder inner wall has integrally formed annular convex platform, is also installed with corresponding annular convex platform in cylinder, between two annular convex platform
It is connected with pvc pipe.
By using said program, sample cell is integrally formed, and length is four meters or more, therefore causes the clear of inside
Reason is difficult, so being arranged with pvc pipe in inside, sample can will not be in direct contact in pvc pipe with sample pipe internal surface, will not
Cause the pollution of sample cell interior surface;Because of the characteristic of pvc pipe material itself, pvc pipe easy cleaning.
Preferably, sampler barrel lower end is detachably fixed and is connected with sampling head.
By using said program, sampling head is the part of direct and seabed contact, and the environments such as subsea at deep-sea is responsible for, no
It can guarantee that the seabed of sample position is soft sand or hard rock, therefore the spoilage of sampling head is very high, in order to protect
The usage time of sampler is demonstrate,proved, therefore sampling head can be dismantled, convenient for the replacement after sampling head damage.
Preferably, sampling head include cylinder and with the integrally formed conical head of cylinder.
By using said program, sampling head is coniform, facilitates sampling head to exert a force to seabed in sampling, conveniently
Sample is removed from seabed, and is in coniform, can also make sample in sampling head to sample in-pipe.
Preferably, being uniformly provided with multiple stress holes on cylinder side wall.
By using said program, in order to prevent in deep seafloor something unexpected happened, so sampling head outer surface is light
It is sliding, therefore sampling head is in installing and dismounting, the place that can be exerted a force of having nothing to do, so sampling head surface is provided with multiple force holes, side
Just the installing and dismounting of sampling head.
In conclusion the utility model has the advantages that:
1. there is multiple angle irons that can be closed automatically in sampler, the side wall of multiple angle irons mutually fits, and makes three

As shown in Figure 6 and Figure 7, annular convex platform 211 is designed with inside cylinder 21 and connecting cylinder 31, between two boss 211
It is connected with pvc pipe 212.
As shown in Fig. 1 and Fig. 9, counter weight device 4 includes with siderosphere 41 and the multiple annulus being installed on 1 outer wall of sample cell
42, reinforcing plate 43 is also fixedly connected between two neighboring annulus 42, and 43 both ends of reinforcing plate are separately fixed at different annular 42
On surface, the gravity for first annulus 42 for being applied to siderosphere 41 and being bonded with siderosphere 41 can be distributed to often by reinforcing plate 43
On a annulus 42, prevents first 42 stress of annulus excessive and fall off;The appearance face paste of inner ring and sample cell 1 with siderosphere 41
It closes, with 41 inner hollow of siderosphere and equipped with lead soil;In annulus 42 and with being provided with identical circular hole 44 on siderosphere 41, in circular hole 44
It is plugged with screw rod 45,45 both ends of screw rod are threaded with screw mother 451, two screw mothers 451 following table with annulus 42 respectively
Face and with siderosphere 41 upper surface fitting;The cooperation of screw rod 45 and screw mother 451 can make all with siderosphere 41 and annulus 42
An entirety is formed, so that center of gravity is compared concentration, prevents centre-of gravity shift from causing sampler that cannot reach seabed vertically.
Specifically used mode:Annulus 42 is welded on 1 suitable position of sample cell, then by 212 grafting sample introduction of pvc pipe
Inside quality control 1, then by sampler 3 and counter weight device 4, the upper and lower ends with sample cell 1 connect respectively, then according to need
It selects to add on annulus 42 a certain number of with siderosphere 41;44 interpolation of circular hole on annulus 42 taps into screw rod 45, then
Screw mother 451 is twisted on the screw rod 45 at 42 lower surface of annulus, be then arranged on screw rod 45 it is multiple match siderosphere 41, add
Add with being fixed again with screw mother 451 after siderosphere 41, then the steel wire rope of external crane is fixed on U-shaped frame 231.
Preparation is completed, and sampler is put into ocean vertically, during sampler enters seawater, sampler barrel 32
Triangle ID iron 323 is acted on by buoyant of sea water, can be flipped up some angles, and seawater enters in sample cell 1, sealing device 2
On lid 247 can be opened by the effect of buoyant of sea water, seawater flows out from the opening 22 of cylinder 21, keeps sampler suitable
Profit enters in ocean;When lid 247 is opened by buoyant of sea water, the angle opened up is prevented by the limitation of crossbeam 232
The angle that only lid 247 is overturn is excessive, and opening 22 can not be covered when being closed.
When sampler contacts seabed, sampling head 324 contacts seabed first, causes sampler barrel 32 sliding in connecting cylinder 31
It moves, connecting cylinder 31 oppresses the protrusion of long strip block 322 in the part in the outside of sampler barrel 32, so that angle iron 323 is beaten by lever principle
It opens, angle iron 323 is fitted in the internal side wall of sampler barrel 32.
Sampling head 324 has conical head 3242, facilitates sample tap 3243 to inject in seabed and is sampled, when sampling completion,
Sampler rises, and under the effect of gravity, for sampler barrel 32 to lower sliding in connecting cylinder 31, connecting cylinder 31 no longer oppresses long strip block
322, because the reason of 323 gravity of angle iron, angle iron 323 has the movement downwardly turned over, because after sampling, in sampler barrel 32
Sample carryover is had, the movement of angle iron 323 can be hindered, so fixed spring 3231 can make spring 3231 on angle iron 323
More easily downwardly turn over.
During sampler rises, the pressure of seawater can by lid 247 being pressed at the opening of cylinder 21 22 tightly,
And 247 bottom of lid fixed toughness rubber cushion 2471, sticky rubber cushion 2471 be under pressure can be tightly be fitted in cylinder 21
It is open at 22;The sample of sample cell 1 can be lifted out in ocean under atmospheric pressure after sampler leaves seawater.
This specific embodiment is only the explanation to the utility model, is not limitations of the present invention, ability
Field technique personnel can as needed make the present embodiment the modification of not creative contribution after reading this specification, but
As long as all being protected by Patent Law in the right of the utility model.
