Abstract
The invention relates to a surface deposit collector of seabed, wherein it has simple operation and high sample success rate; and it is formed by main body of collector and extracting ring; the invention is characterized in that: the main body of collector is barrel; the barrel open has outward-incline plow-shaped valve; the barrel has discharge hole; and the barrel open is mounted with movable extracting ring.
Description
Technical field:
The present invention relates to the superficial deposit matter collection device that marine eco-environment investigation is used.
Background technology
The grab type bottom sampler is generally used in the collection of present domestic marine eco-environment investigation mesexine sediment.This kind bottom sampler mainly is made of two mobilizable jaw lobes.Two jaw lobes area 0.1m that dehisces
2Two jaw lobe tops are connected by an iron chains, and when iron chains was suspended on the hook of wire rope end, two jaw lobes were open state, and when bottom sampler touches the seabed, iron chains breaks off relations.When carrying on the bottom sampler, connect the wire rope tension of two jaw lobes, make two jaw lobe closures, sediment is grabbed into grab bucket.In addition, also have a kind of Smith-McIntyre grab, this kind bottom sampler mainly makes left and right sides jaw insert sampling in the sediment by spring action, its complicated operating process and loaded down with trivial details.In coastal waters or rivers surface deposit gatherer process, owing to influenced by trend or be subjected to the restriction of substrate condition, closing voluntarily appears in grab type bottom sampler regular meeting, and gathers less than sample or repeat repeatedly to gather and change the longer acquisition time of expense.If use the bottom sampler or the Smith-McIntyre grab that increase the weight of often to be investigated the ship condition restriction again, bring many operational inconvenience for marine investigation work.
Summary of the invention
The technical issues that need to address of the present invention provide a kind of easy to operate, be sampled into the high surface deposit sampler of power.
Technical scheme of the present invention is made up of collector main body and drop handle, it is characterized in that the collector main body becomes tubbiness, and bung has the plow-shaped valve of flare, and ladle body has weep hole, bung installation activity drop handle.
The present invention is owing to be provided with the plow-shaped valve of flare on the mouth edge of collector main body, can increase collector and grab the sedimental ability of digging, collector touches accumbency behind the seabed, the plow-shaped valve oblique cutting of point tax is gone in the surface deposit, on when carrying under oblique pulling force effect, collector translation process mesexine sediment is grabbed through plow-shaped valve and is entered in the bucket after digging; Weep hole on the collector ladle body can excrete out the seawater that enters in the bucket with surface deposit, is beneficial to sedimental collection.Simple surface deposit sampler reaches substantially and once samples successfully through repeatedly marine test, can collect the sediment sample of 70 meters depth of waters, has easy to operate, practical advantage.
Description of drawings
What accompanying drawing was represented is structural representation of the present invention.
Embodiment
The simple surface deposit sampler main body becomes long barrel shape, adopts the steel pipe 1 of diameter 250mm, thickness 5mm to make, and the long 550mm of body, the long 63mm of plow-shaped valve 2 teeth, the steel plate of the bucket end with 5mm seal total length 618mm; Bung girth etc. is cut apart and 30 degree that lean outward bend to plow-shaped valve 2, is used to increase collector to grab the sedimental ability of digging; Weep hole 3 preferably is located at the above ladle body apart from bucket end 100mm, the aperture of weep hole is strengthened from bottom to top gradually, the aperture of weep hole can be respectively 5mm, 7mm, 9mm, 12mm from bottom to top, and the seawater of being convenient to enter in the bucket with surface deposit excretes out, and is beneficial to sedimental collection; A movable drop handle 4 of being made by the line steel of diameter 5mm is installed at the bung place, and movable drop handle 4 has the triangle clasp.In addition, the nearly bunghole part vertical with drop handle bores the fixed orifice that increases the weight of that an aperture is 7mm, can be convenient to the weight that increases collector at the suitable additional bob-weight in this hole under special circumstances.
