Description
Technical field
The present invention relates to marine sediment acquisition technique fields, specifically a kind of to be suitable for aquafarm benthic environment
The deposit of investigation acquires and cutting device.
Background technique
The acquisition of Sediments sample is the important component with environmental survey between oceanic tide, and sediment sample can be used for
Relevant coastal geology, ecological environment research and analysis.Aquafarm building is marine fishery resources sustainable use and hair
An important ring for exhibition, construction need the environmental survey and evaluation work of science with maintenance.Aquafarm benthic environment is numerous
The habitat of important marine economic living (such as sea cucumber, abalone), and sediment sample mentions in the 10cm of its surface layer for benthon
Main habitat and food source are supplied, it is monitoring environmental change, prediction cultivation that regular investigation sampling is carried out to it
The important means of risk.It is surveyed it is emphasized that often needing to acquire simultaneously in benthic environment investigation for the abiotic index of environment
Two kinds of samples of fixed and benthic community measurement.
Not stratified sampling and two kinds of stratified sampling are divided into aquafarm benthic environment investigation and sampling at present, the former is with box
Bottom sampler or grab bucket bottom sampler realize that the latter is realized with all kinds of profile leads.Since layering sample can provide aquafarm
About the more accurate detailed data of benthic environment, adopt in sample size abundance situation, stratified sampling is better than not stratified sampling.
Existing profile lead mainly has gravity type profile lead, piston type profile lead, multichannel profile lead, small at present
Type profile lead etc..Wherein, former three using when need heavy mechanical equipment to assist, be not suitable for aquafarm small boat
Sampling, and the sinking of commercially available small-size columnar bottom sampler (the kajak bottom sampler that such as KC-Denmark company produces) single can only obtain
A piece columnar samples, thus be not able to satisfy in the investigation of aquafarm benthic environment in same small area region (< 1m2) in obtain 3~4
Columnar samples, the sampling request to reduce repeat samples Spatial Variability.
Marine sediment columnar samples load container mainly have stainless steel tube, lucite tube, with three kinds of PP plastic tube.Because at
This is lower, and sample and sampling pipe are often pressed required section length integral cutting after the sampling of PP plastic tube, and stainless steel tube with it is organic
Glass tube sample needs mating logical sampling device by the bottom-up pass-out of sample.Presently commercially available logical sampling device is mostly that metal is made and easy
Corrosion, or be equipped with more complicated height of specimen measurement and be unfavorable for sample site with cutting component and quick and precisely cut, and is existing
Horizontal slice cutting can only be carried out for the cutting device of small-sized sediment cores, is unable to perpendicular bisected cutting, it is difficult to full
The same columnar samples of foot provide the sampling requirement of two kinds of samples of the abiotic index determining of environment and benthic community measurement.
Summary of the invention
Invention be designed to provide it is a kind of suitable for aquafarm benthic environment investigation deposit acquisition with cutting fill
It sets, wherein sample boxes can make diver in a dive, in same small area the region (< 1m in aquafarm bottom2) in take
3~4 cylindrical samples are obtained, it can be rapidly by point of depth needed for the 10cm of surface layer using the sample ring of cutting that logical sample seat and height determine
It simultaneously two parts of equal part of layer sample pass-out, is respectively used to environmental index measurement and is measured with benthic community.
The purpose of invention is achieved through the following technical solutions:
A kind of deposit acquisition and cutting device suitable for the investigation of aquafarm benthic environment, including sample boxes, sampling

Just it is inserted into the mud of seabed, the sample boxes 1 and cuts sample ring 15 and be made of stainless steel.
The operation principle of the present invention is that:
Before sampling, 3~4 sampling pipes 2 are placed in sample boxes 1, the string bag 4 is tied to 1 side of sample boxes, and by 6~8 pieces of glue
Plug 3 is put in the string bag 4 and string bag mouth cord pumping consolidation is showed the closing of pocket mouth, by the 7 hook jail of hook on frame lid 5 in frame body 8
It goes up and is bound by rubber band, to guarantee that sampling pipe 2 will not fall off sample boxes 1 in sinking watching, with long enough (to investigate the depth of water
Twice or more) rope be securely tie up lifting rope 9, then with manpower by sample boxes 1, sampling pipe 2, rubber plug 3 and the string bag 4 suspension sink to sea
Bottom.The present embodiment is suitable for the silt substrate coastal ocean farming areas within 36 meters of the depth of water (skin diving safety depth), adopts
Sample equipment, which sinks, draws in row by band rope system, research vessel institute with floating.
Hook 7 is solved extension in seabed and opens frame lid 5 by diver, then takes out sampling pipe 2, and by sampling pipe 2 with chamfering
One end downward, vertical pressing 20~30cm in surface deposit it is deep, then by taking out one piece of sealing sampling of rubber plug 3 in the string bag 4
2 upper end of pipe keeps its holding closed, and related the acquired sediment sample of sampling pipe 2 is firmly then extracted bed mud circle vertically upward
Face, then 2 lower end of sampling pipe is sealed with another piece of rubber plug 3, it leaks out sample 14 not, the sampling pipe 2 is then placed in sample boxes 1
In an interior lattice, need to keep sample 14 vertical in operation, according to this process in 1m2Point of proximity in range acquires 3~4
Hook 7 is mounted on frame body 8 by columnar deposit sample again later, covers frame lid 5, then by inquiry ship rope will more than
Sampling apparatus and acquired sample pull out the water surface, are vertically placed on investigation boat deck and complete sampling.
Sample slowly takes out the sampling pipe 2 for filling sample 14 when cutting from sample boxes 1, preferably firmly presses before taking out
Upper end rubber plug 3, making bottom plug 3, securely then the sampling pipe 2 is placed in logical 10 top of sample seat, taken out by plug on sampling pipe 2
The 2 lower end rubber plug 3 of sampling pipe pays attention to temporarily being sealed when rubber plug 3 will be separated with 2 bottom end of sampling pipe with a flat steel shovel
2 bottom end of sampling pipe is blocked up, prevents sample 14 from dropping out, 2 lower end of sampling pipe is placed on the top plate 11 of logical sample seat 10, is taken out
The 2 upper end rubber plug 3 of sampling pipe, then slowly presses down on the sampling pipe 2, cutting for desired height is taken after overlying water is flow to end
Sample ring 15 is placed in 2 upper end of sampling pipe and is overlapped the two its internal diameter circle, whole to press crush-cutting sample ring 15 and sampling pipe 2, with pass-out institute
The columnar deposit sample 14 of depth is needed, then with steel shovel along the gap horizontal resection sample cut between sample ring 15 and sampling pipe 2
14, then with spoon by sample 14 from pass-out in sample ring 15 is cut, be subsequently placed in save container in.
