Abstract
The utility model relates to a sampler of surface soft sediment. The sampler comprises a sampling head, a mud storage cavity, an aggravate mechanism and an upper sealing cover. The sampling head is a drum; the bottom end is open; a mud inlet plate is arranged at the upper end; the mud storage cavity is the drum; two small suspension links are symmetrically arranged at the upper part; a sealing ball is arranged in the middle and tied on the suspension links through locating ropes; a housing of the aggravate mechanism forms the drum; a through pipe is arranged at the center; a heavy object is placed between the housing and the through pipe; the two suspension links are symmetrically arranged at the external part of the upper end. The sampler of surface soft sediment is convenient to use, simple in structure, and convenient to maintain, can be dismantled, and is applicable to collection of thick soft sediment.
Description
Technical field
The utility model relates to the Sediments sampling instruments such as a kind of rivers, lake, reservoir, refers in particular to a kind of sampling thief for the soft bed mud in water bottom top layer.
Background technology
In recent years along with economic, social development, the water pollutions such as rivers, lake, reservoir are more and more serious, reservoir water body pollutes to be removed outside upland water impact, also has a very important Causes for Pollution various poisonous and harmful substances in mud at the bottom of water body to interact, react and be discharged in water body and cause.The composition of understanding in detail bed mud is very important, and especially the composition of water bottom sediments, more can reflect the polluter that is discharged in the recent period water body, for relevant functional department provides reference, concentrates and investigates and prosecutes the pollution source relevant with control.
Existing sediment sampler, be difficult to collect the sediments that soft sediment layer is thicker, such as the sediment sampler of grab type, due to the gravity of self, cause sampling thief to sink to the place below top layer, the mud in the process of sinking in grab bucket has been replaced by the mud below top layer.The sediment sampler that also has cylindricality, due to the gravity of self, sinks in thicker soft sediment layer equally, and bed mud floods sampling thief top, and the bed mud in sampling thief also can be changed along with sinking the bed mud of respective depth, gets less than sediments.
Summary of the invention
The purpose of this utility model, is to provide a kind of top layer soft sediment sampler for problems of the prior art, can guarantee to gather the bed mud sample that sample is top layer, easy to use, simple in structure, can split, and is convenient to maintenance.
The utility model is realized by following technical scheme.
The soft sediment sampler in top layer of the present utility model comprises: sampling head, storage mud chamber, increase the weight of mechanism and upper cover.Sampling Yu Chuni chamber, head upper end lower end screwed connection, stores up upper end, mud chamber and increases the weight of mechanism's lower end screwed connection, increases the weight of the lower end screwed connection of mechanism upper end and upper cover.Sampling head is cylinder, open bottom end, and upper end is provided with into mud plate.Storage mud chamber is cylinder, and upper and lower side is all provided with interior screw thread, and top is symmetrically arranged with two little draw rings, and there is ball sealer centre, by positioning rope, lies on draw ring.Increase the weight of mechanism shell and form cylinder, there are male thread and back up pad in lower end, and center is provided with siphunculus, between shell and siphunculus, places weight, and upper end is provided with interior screw thread, and upper end outer symmetrical arranges two draw rings.Upper cover lower end is provided with male thread, and lid center is porose.
Describedly enter mud plate middle part and be provided with some mud holes of entering, shell fragment is set entering top, mud hole, shell fragment bottom is stained with sheet rubber, and shell fragment one end is fixed on mud plate.
The density of described ball sealer is between water and the density of bed mud.
The volume of described sampling head is greater than the volume in storage mud chamber.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation into mud plate.
Embodiment
Below in conjunction with accompanying drawing, with specific embodiment, the utility model is further described, referring to Fig. 1-2.
The sampling thief of the soft bed mud in top layer of the present utility model comprises: sampling head 1, storage mud chamber 2, increase the weight of mechanism 3 and upper cover 4.1 Yu Chuni chamber, the upper end 2 lower end screwed connections of sampling head, store up 2 upper ends, mud chamber and increase the weight of mechanism's 3 lower end screwed connections, increase the weight of the lower end screwed connection of mechanism 3 upper ends and upper cover 4.Sampling head 1 is cylinder, open bottom end, and upper end is provided with into mud plate 5.Storage mud chamber 2 is cylinder, and upper and lower side is all provided with interior screw thread, and top is symmetrically arranged with two little draw rings 10, and there is ball sealer 12 centre, by positioning rope, is 11 on draw ring 10.Increase the weight of mechanism's 3 shells and form cylinder, there are male thread 13 and back up pad 31 in lower end, and center is provided with siphunculus 14, between shell and siphunculus 14, places weight 15, and upper end is provided with interior screw thread, and upper end outer symmetrical arranges two draw rings 16.Upper cover 4 lower ends are provided with male thread, and lid center is porose.
Describedly enter mud plate 5 middle parts and be provided with some mud holes 6 of entering, shell fragment 7 is set entering 6 tops, mud hole, shell fragment 7 bottoms are stained with sheet rubber 8, and shell fragment 7 one end are fixed on mud plate 5.
The density of described ball sealer 12 is between water and the density of sediments.
The volume of described sampling head 1 is greater than the volume in storage mud chamber 2.
The work engineering of this soft sediment sampler in utility model top layer is as follows.
First, open upper cover 4, by increasing or reduce the weight block 15 increasing the weight of in mechanism 3, increase the weight of or alleviate the own wt of sampling thief, then tighten upper cover 4.If sampled point exists undercurrent under water, can increase the weight 15 increasing the weight of in mechanism 3, to guarantee that sampling thief can accurately fall sample point, if the water surface and tranquil can reduce the weight 15 increasing the weight of in mechanism 3, to alleviate sampling thief gravity, handled easily under water.
User is on bank or ship, use rope to lie on draw ring 16, sampling thief is slowly put into water body, when sampling head 1 lower end touches after bed mud, along with sampling thief slowly sinks, the soft bed mud on top layer can successfully enter in the cylinder of sampling head 1, intrasystem water can flow out by siphunculus 14, when bed mud touches into mud plate 5, bed mud in cylinder is sediments, bed mud by enter mud plate 1 enter mud hole 6 time be subject to resistance, gravity due to sampling thief self, sediments in cylinder can be pressed into into mud hole 6, push shell fragment 7 open and enter storage mud chamber 2, the interior bed mud in storage mud chamber 2 rises to certain altitude and can hold up ball sealer 12, when bed mud rises to maximum height, ball sealer 12 seals siphunculus 14 lower ends exactly by positioning rope 11, after this, during sampling thief sinks, bed mud in storage mud chamber 2 no longer increases, tow promotes sampling thief, in the process that sampling thief rises, shell fragment 7 is subject to storing up the downward pressure of mud chamber 2 interior bed muds, joint rubber sheet 8 seals into mud hole 6, fast lifting sampling thief is to bank or ship, back out and increase the weight of mechanism 3, shift the bed mud in storage mud chamber 2, with clear water, clean sampling thief.
