Abstract

A mechanical handheld type deposit sampler consists of a knife pot assembly and a bush assembly. The knife pot assembly includes the hand bar, the upper end cover, the knife pot and the inserting tube. The bush assembly installed in the knife pot assembly includes the brush cover, the filter screen and the bush, and the claw petal. The manipulator grasping the T type hand bar inserts the sampler down into the marine deposits vertically. In the inserting procedure, the seawater through the filter screen and the drain hole is discharged outside. With the deposit touching the cover of the bush, the bush is brought to move upwards. When the cover touching the locknut, the claw petal is closed to cut off the deposit, sealing the opening so as to complete the sampling operation.

Description

The mechanical hand-held formula sediment sampler of non-boundary disturbance

Technical field

The present invention relates to a kind of mechanical hand-held formula sediment sampler of non-boundary disturbance.

Background technology

Measuring deep-sea submarine hydrothermal solution and sedimental chemical state, and dissolved constituents content in the hydrothermal solution, is one of ocean resources environment main task of reconnoitring, and also is the basic means of oceanographic research.Be subjected to the restriction of sampling condition, the ocean resources detection operations of China can only adopt traditional method of sampling at present, promptly throw in sampling thief from ship at sea, gather a large amount of hydrothermal solutions and the thalassogenic sedimentation matter sample of the diverse location and the degree of depth on a large scale, again sample is carried out chemical dissolution component analysis on Content after getting back to the laboratory.Lacking sampling accurately so often wastes lot of manpower and material resources, can not obtain the excellent research effect.

Summary of the invention

The mechanical hand-held formula sediment sampler that the purpose of this invention is to provide a kind of non-boundary disturbance can developed the deep-sea manned deep-sea vehicle for China, by the submarine mechanical manual manipulation, carries out sampling analysis in the seabed.The technical solution used in the present invention is that it comprises following two parts:

1) cutter cartridge unit: comprise holding rod, upper end cover, the cutter tube is inserted tube; Cutter tube upper port is equipped with the upper end cover of opening the hole, and holding rod is housed on the upper end cover, and step-like slotting tube is housed in the cutter tube bottom hole, tightens up with screw behind the great circle cylinder of slotting tube and the cutter tube bottom hole close-fitting, and roundlet cylinder and the cutter tube of inserting tube keep the gap;

2) lining parts: comprise the lining lid, metal screen, back-up ring, lining, plum blossom lobe circle; The lining lid, metal screen and the back-up ring that have through hole join together in the upper hole of the lining of packing into, the circular bead surface of lining lid and lining end face stick with glue and connect, the plum blossom lobe circle of flexure strip is housed in the hole of lining bottom, the roundlet cylinder of plum blossom lobe and slotting tube forms and is slidingly matched, and lining is contained in to form in the cutter tube and is slidingly matched.

Cutter tube lower end side and slotting tube lower end side and end face form 60 ° the edge of a knife.

The present invention compares with background technology, and the useful effect that has is: it is that special ROV of confession of a cover and manned deep-sea vehicle utilize mechanical arm to carry out the passive sampling apparatus of sediment sampling at the deep-sea.This device volume is little, in light weight, and is simple to operate, is convenient to mechanical arm sampling in the seabed is fixed a point among a small circle, and can keeps sample not have disturbance, the sequence fidelity.

Embodiment

Be structural representation of the present invention as shown in Figure 1.

The cutter cartridge unit: comprise holding rod 1, upper end cover 3, cutter tube 7 is inserted tube 10; Cutter tube 7 upper port are equipped with the upper end cover 3 of opening the hole, holding rod 1 is housed on the upper end cover 3, step-like slotting tube 10 is housed in cutter tube 7 bottom holes, tightens up with screw behind the great circle cylinder of slotting tube 10 and the cutter tube 7 bottom hole close-fittings, roundlet cylinder and the cutter tube 7 of inserting tube 10 keep the gap.

Cutter tube 7 tops connect with upper end cover 3 with screw thread, and T type holding rod 1 connects with upper end cover 3 by set nut 2, is convenient to Robot actions.Cutter tube 7 bottoms connect with slotting tube 10 with screw, and this structure can make in the lining 8 and be in complete open configuration (as shown in Figure 2) before 9.1 samplings of plum blossom lobes, and sampling is finished and closed up cut-out sample (as shown in Figure 3), the not disturbance that keeps sample.The cutter tube bottom has 60 ° the edge of a knife, is convenient to insert sampling in the sediment.

Lining parts: comprise lining lid 4, metal screen 5, back-up ring 6, lining 8, plum blossom lobe circle 9; The lining lid 4, metal screen 5 and the back-up ring 6 that have through hole join together in the upper hole of the lining 8 of packing into, the circular bead surface of lining lid 4 and lining 8 end faces stick with glue and connect, the plum blossom lobe 9.1 of flexure strip is housed in the hole of lining 8 bottoms, the roundlet cylinder of plum blossom lobe circle 9 and slotting tube 10 forms and is slidingly matched (as Fig. 1, shown in Figure 4), and lining 8 is contained in to form in the cutter tube 7 and is slidingly matched.

Lining top is made of lining lid 4, metal screen 5 and back-up ring 6, can prevent that sediment sample from overflowing and can discharge lining 8 maritime interior waters.Stick with glue between lining lid 4 and lining end face and connect.Lining 8 bottoms are plum blossom lobe 9.1 fixedly, is used to cut off sample and seals.

The course of work: mechanical arm clamps T type holding rod, and sampling thief is vertically inserted in the marine bottom sediment.In slotting process down, the tube maritime interior waters passes through metal screen 5 and upwards discharge of osculum, can move upward by drive linings 8 when sediment pushes up lining lid 4.When lining lid 4 was run into upper lock jack panel 2, lining 8 bottom plum blossom lobes 9.1 break away from inserted tube, closes up the cut-out sediment, and realizes sealing, and finishes sampling action.

This sampling thief adopts double-tube structure, and inboard lining 8 is by external diameter φ 80mm, and the organic glass tube of 4mm constitutes behind the wall, is used for gathering and preserving sediment sample, and the efficiently sampling degree of depth is 130mm (the efficiently sampling volume is more than 0.5 liter); Outer side tool tube 7 is external diameter φ 96mm, and the stainless steel cylinder of 8mm behind the wall mainly plays the inner lining of protection.
