Abstract
An underwater soil sampler relates to a soil sampling device, in particular to an underwater soil sampler which is suitable for deep water soil sampling and can keep the structural wholeness of soil. The underwater soil sampler is characterized in that a handle, a sampler, and a push rod are comprised; the sampler adopts a hollow stainless steel tube with two ends opened; one end of the sampler is cut into a slope and the other end of that is movably connected with the handle; the push rod is matched with the sampler; and soil in the sampler is pushed out through the push rod to avoid damage on soil structure. The underwater soil sampler provided by the utility model has a simple structure, is convenient to use, can sample continuous soil 60cm to 100cm underwater in one attempt, and avoids damage on soil structure since the soil is pushed out in whole through the push rod, thereby facilitating soil structure and property analysis in a laboratory.
Description
Technical field
The utility model relates to a kind of soil sampling device, especially a kind ofly is applicable to the deep water soil sample, and can keep the soil sampler under water of soil complete structure.
Background technology
In physicism, need collect, sample materials such as soil, atmosphere, water, then sample is moved to the lab analysis chemical examination.Big G&W all belongs to than the material that is easier to gather, and only needs simple utensil just can carry out sample collecting.For soil, how complete collection pedotheque always is the quite work of difficulty.In soil and Study of Water Environment, usually need from underwater sediment(s)s such as river, lake, wetland, extract pedotheque.Pedotheque water percentage under water is high, flow-like, and the sampling difficulty is big.In sampling process, bed mud disturbance, sample disengaging or loss take place owing to influenced by water body, can't keep bed mud structure original state, can't carry out quantitative, depthkeeping degree sampling, thereby influence the accuracy of research work.
Existing soil sample collector, its ST and handle, connecting link all are connected as a single entity with fixed form, and connecting link is solid iron staff, and ST is the long hollow circular cylinder of 10cm that is; Open a groove on the ST sidewall, owing to connecting link is fixedly connected with ST, after taking a sample in the insertion soil; Use foreign object soil to be plucked out, but destroyed soil texture like this, be unfavorable for soil analysis through the groove on the ST sidewall; And because mostly this type of soil sample collector is to use by land is designed, when taking under water pedotheque, at every turn multipotency is taked the sample of 10cm; When more the soil of deep layer carries out sample analysis, just need repeatedly sampling of fixed point, because under water; Receive that water flow disturbance, mud flow and the influence of water body obstruct the view, can't repeatedly take a sample accurately, be unfavorable for soil analysis under water the same point position.
Summary of the invention
The utility model exactly existing soil sample collector to be solved is inappropriate for and gos deep into sampling in the water, and destroys the problem of soil texture easily, provides a kind of and is applicable to soil sample under water, and can not break the soil sampler under water of meeting soil texture.
The soil sampler under water of the utility model; It is characterized in that this device comprises handle, ST and push rod, ST is the hollow stainless-steel tube of both ends open, and ST one end is the inclined-plane otch; The other end and handle flexibly connect; Push rod and ST coupling are released the soil in the ST through push rod, avoid destroying soil texture.
Described handle is formed " fourth " font by cross bar and montant, and cross bar is the bar of exerting oneself, and montant is the hollow stainless-steel tube, and the montant internal diameter is greater than the ST external diameter, and an end is fixedly connected other end opening with the bar of exerting oneself.
All be provided with at least three pin holes on the tube wall of described ST top and montant bottom from top to bottom, the montant of ST and handle connects with pin through pin hole.
Through the link position of pin hole adjusting handle and ST, can in sampling process, regulate the active length of ST, make its length greater than the depth of water and sampling depth sum, increase the degree of depth of sampling.
Described push rod one end is a handgrip, and the other end is a circular head plate, and its diameter equals the ST internal diameter, and the length of push rod is used for the soil in the ST is released greater than the length of ST.
Insert ST in the soil under water, after the degree of depth that arrival needs, ST is taken out through handle; Take off handle then, release through the soil that push rod is inner with ST, not only easy to use; And can not destroy soil texture, be convenient to analyze structure, physics and the chemical property of soil.
The soil sampler under water of the utility model, simple in structure, easy to use; Can be as required at the underwater work of different depth, the disposable continuous soil of 60-100cm under water of taking is released soil integral body with push rod; Avoid destroying soil texture, be beneficial to structure, the character of lab analysis soil.

Embodiment
Embodiment 1: a kind of soil sampler under water; Comprise handle 1, ST 3, push rod 6 and pin 8, ST 3 is the hollow stainless-steel tube of both ends open, and the one of which end is an inclined-plane otch 4; Be sharp edge shape, be provided with three pin holes 2 on the other end tube wall from top to bottom; Handle 1 is formed " fourth " font by cross bar and montant; Cross bar is the bar of exerting oneself, and montant is the hollow stainless-steel tube, and the montant internal diameter is slightly larger than ST 3 external diameters; Montant one end is fixedly connected with the bar of exerting oneself; Other end opening, its tube wall are provided with three pin holes 2 that are arranged above and below, and handle 1 is connected through pin hole 2 usefulness pin 8 with ST 3; Push rod 6 one ends are handgrip 5, and the other end is provided with a circular head plate 7, and push rod 6 length are taken over a business 7 diameters and equaled ST 3 internal diameters greater than ST 3 length, and sampling back utilizes 7 soil released.
During use, with pin 83 flat mouthfuls of ends of handle 1 and ST are connected earlier, ST 3 otch one end inserts in the soil under water; After the degree of depth that arrival needs, the soil in the handle 1 related ST 3 is taken out simultaneously, take off handle 1 then; Hold the handgrip 5 of push rod 6; Utilization takes over a business 7 with the soil release, avoids destroying soil texture, helps the analysis of laboratory to structure, physics and the chemical property of soil.
