Abstract
The utility model belongs to biological sampling technical field, is specifically related to a kind of marine benthos sampling thief.This marine benthos sampling thief, comprise sampling head, sample channel, power pump and biological sieve, described power pump one end is connected with sampling head by sample channel, one end is connected with sample channel in addition, sample channel is communicated with Tail water reuse pipe by biological sieve, biological sieve is connected by the mode be spirally connected with sample channel and Tail water reuse pipe, and the sample channel between described power pump and sampling head is provided with sample flow determinator.Its beneficial effect is: safe and reliable, guarantee that sample does not run off, not stained, simultaneously, tail water after sampling can directly be disposed to marine by Tail water reuse pipe, keep operating area clean and tidy, buoyancy closed valve when sampling head sinks, can play reduction current and disturbs the buoyancy of sampling head, sampling head is steadily sunk.
Description
Technical field
The utility model belongs to biological sampling technical field, is specifically related to a kind of marine benthos sampling thief.
Background technology
Marine benthos refer to the biology of dwelling in Yu Haiyang substrate surface or sediment.The ocean hadal zone of this kind of biology more than mesolittoral zone to depth of water myriametre has existence, is an ecotype of most species in sea life, includes most of marine animal class, tangleweed and ocean spermatophyte.
At present, existing Marine organism sampler mainly carries out collection sampling for planktonic organism, and publication number is the Chinese utility model patent of CN2784907, disclose a kind of Pneumatic benthos sampler, arrange a pair by a left side, the oval mechanics skeleton of right bow-shaped arm synthesis, top dress turning joint, turning joint pin is equipped with bail, left, right bow-shaped arm lower end level installs pair of parallel relative cutter head, a slide bar is connected in each cutter head one end, the other end arranges a locating ring, two cutter head setting positions are contrary, the slide bar free end of two cutter heads inserts respectively in the locating ring of the other side and is slidably matched, left, the head of difference chain connection one pneumatic piston inside right bow-shaped arm waist, tail two ends, except the oblong openings formed after two cutter heads are separated, sampling thief is connect coated by guard.This sampler structure is complicated, and uses cylinder, is not easy to control and hand-held.
On Dec 2nd, 2009, publication number is CN201355314 Chinese utility model patent, disclose a kind of hand-held box type benthos sampler, this sampling thief is provided with sampling box, shovel and for manually-operated hand-held device, sampling box upper surface and bottom surface opening, shovel is located at below sampling box, the shape of shovel and sampling box bottom surface coincide, hand-held device is provided with shape fixed bar and a movable rod, door shape fixed bar is fixed on sampling box, the cross bar of door shape fixed bar is provided with hook, the montant of door shape fixed bar both sides is provided with a block, prop up block to be flexibly connected with movable rod, the end of movable rod is affixed with shovel.This sampling thief can only carry out spot sampling operation, is not suitable for towing sampling at the bottom.
Utility model content
The utility model, in order to make up the defect of prior art, provides a kind of safe and reliable, guarantees that sample does not run off, not stained, keeps the marine benthos sampling thief that operating area is clean and tidy.
The utility model is achieved by the following technical solution:
A kind of marine benthos sampling thief, comprise sampling head, sample channel, power pump and biological sieve, described power pump one end is connected with sampling head by sample channel, one end is connected with sample channel in addition, sample channel is communicated with Tail water reuse pipe by biological sieve, biological sieve is connected by the mode be spirally connected with sample channel and Tail water reuse pipe, and the sample channel between described power pump and sampling head is provided with sample flow determinator.
Further, described sampling head is tapered, and sampling head is provided with buoyancy closed valve, is provided with thief hatch bottom it, and thief hatch place is provided with zigzag and changes pool.
Further, described Tail water reuse pipe end has Tail water reuse mouth.
Further, described power pump is the power unit of whole system, adopts ups power design, solves unregulated power feed region and uses.
The beneficial effects of the utility model are: a kind of marine benthos sampling thief of the utility model is safe and reliable, biological sieve can arrange the sieve of different meshes according to sampling request, use sampling bottle supporting with it, directly this sieve is positioned in sampling bottle, with water, sample is recoiled in sampling bottle, guarantee that sample does not run off, not stained, simultaneously, tail water after sampling can directly be disposed to marine by Tail water reuse pipe, keep operating area clean and tidy, buoyancy closed valve can when sampling head sinks, play reduction current to disturb the buoyancy of sampling head, sampling head is steadily sunk.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further described.
Accompanying drawing 1 is structural representation of the present utility model;
In figure, 1 sampling head, 2 sample channels, 3 sample flow determinators, 4 power pumps, 5 biological sieves, 6 Tail water reuse pipes, 7 zigzags change pool, 8 buoyancy closed valve, 9 thief hatchs, 10 Tail water reuse mouths.
Embodiment
Accompanying drawing 1 is a kind of specific embodiment of the present utility model.A kind of marine benthos sampling thief of this utility model, comprise sampling head 1, sample channel 2, power pump 4 and biological sieve 5, described power pump 4 one end is connected with sampling head 1 by sample channel 2, one end is connected with sample channel 2 in addition, sample channel 2 is communicated with Tail water reuse pipe 6 by biological sieve 5, biological sieve 5 is connected by the mode be spirally connected with sample channel 2 and Tail water reuse pipe 6, and the sample channel 2 between described power pump 4 and sampling head 1 is provided with sample flow determinator 3.
Further, described sampling head 1 is tapered, and sampling head 1 is provided with buoyancy closed valve 8, is provided with thief hatch 9 bottom it, and thief hatch 9 place is provided with zigzag and changes pool 7.
Further, described Tail water reuse pipe 6 end has Tail water reuse mouth 10.
The utility model is not limited to above-mentioned embodiment, anyone should learn make under enlightenment of the present utility model with the utility model, there is identical or close technical scheme, all fall within protection domain of the present utility model.
Technology, shape, structure part that the utility model is not described in detail are known technology.
