Specific embodiment
A kind of river bottom mud and water sample original sample collector, including following 4 parts:
1, organic glass sampling cylinder 1(length L can be in 1.0-1.5m, and actual samples depth < L, diameter D can be in 5-10cm).
2, top driving and lock structure:
Upper internal threaded ring 5, lower internal thread ring 6, activity annulus 3(include that connection strut 12 connect stock installation with metal
Hole), external thread sleeve 4(screw 13, swivel nut 14, antiskid rubber 15 be fixed on the outside of organic glass sampling cylinder), connect strut 12
Metal connect stock mounting hole closed upper part, metal connection stock is inserted into the hole when use.
Screw (including nut or swivel nut and antiskid rubber) one shares 8, respectively in the top of external thread sleeve and lower part, on
Under each 4, external thread sleeve is secured firmly to organic glass sampling cylinder outer upper.
3, the fixed device in middle part includes:
Connecting rod fixator 10(may be deformed after connecting the longer multiple stress of stock due to metal, so being fixed using a connecting rod
Device prevents its bending deformation).
4, lower part enclosed construction:
The petal bottom sealing plate of climing 8(is spent in metal connection stock 2, metal bottom closed-loop (liner rubber) 16, bottom), pedestal (is used for
With petal bottom sealing plate, connect quarter butt fixed connection place be flexibly connected, connection quarter butt and bottom sealing plate lateral wall top in 90 ° folder
Angle is vertically fixedly connected).
Collector of the invention is when extracting the water sample and deposit in small-sized river:
The installation of each component is fixed first, upper upper internal threaded ring, lower internal thread are covered by revolving outer nut simultaneously
Ring, two internal screw thread ring clamping activity annulus, improves the position of movable annulus, and it is short to connect stock dragging connection by metal
Bar pulls petal bottom sealing plate, that is, it is climing to open spending for bottom, it is ensured that the tip of petal bottom sealing plate is placed in organic glass sampling cylinder
The outside of inner sidewall extended line (i.e. organic glass sampling cylinder bottom is without underseal component)；
Then it inserts the sampler into the depth envisioned under water or inserts when not going down, reversely rotate external nut and cover spiral shell in upper top
Line ring, lower internal thread ring, clamping activity annulus reduce the position of movable annulus, driving metal connection stock, connection quarter butt
The petal bottom sealing plate of closing bottom makes four petal bottom sealing plates form hollow hemisphere in organic glass sampling cylinder bottom closure
Structure uses watertight rubber sealing between petal bottom sealing plate；
Then collector of the present invention is taken out from water, the gap between the connecting rod base and organic glass sampling cylinder of metal ring
Leak is prevented using liner rubber ring 16.The water sample being extracted can be kept in organic glass sampling cylinder (having scale) and sunk
The layering physical aspect of product object is not destroyed, to realize the water sample of different depth, Sediments while extract, takes back experiment
Room different depth in organic glass sampling cylinder is accurately layered double sampling test, improves the accuracy of experiment.
Sampling cylinder uses lucite cylinder, and movable annulus, connecting rod fixator, petal bottom sealing plate use stainless steel, petal
Shape bottom sealing plate periphery watertight rubber sealing.
