Abstract
The utility model provides a gas striping type stream sediment sampler. The gas striping type stream sediment sampler comprises a net head, a piston, a barrel, a barrel cover and a push-pull rod, wherein the net head is arranged at the lower end part of the barrel; the barrel cover is arranged at the upper end part of the barrel; the push-pull rod with a handle penetrates through the barrel cover and is connected with the piston in the barrel. The gas striping type stream sediment sampler is simple in structure, easy to fabricate, low in cost and convenient to operate, and the stream sediment can be quickly sampled.
Description
Technical field
The utility model belongs to a kind of artificial sample instrument, specifically a kind of vapour-pressure type sampling thief for sediments sampling.Be applicable to the sampling in the fields such as ground materialization spy, hydrogeology and environmental monitoring.
Background technology
While taking sediments sample with sampling spoon, conventional artificial sample spoon, in order to guarantee the accuracy of sampling, should note: the width of sampling spoon opening is suitable; Sampling spoon should have smooth inwall, and every sub-sampling sampling spoon volume should be greater than the once required volume of sediments amount of intercepting.In taking the experimental implementation process of sediments sampling, use sampling spoon or not perfect, have the following disadvantages:
1., even if the inwall of sampling spoon is smooth, topples over sediments and be still not easy.As everyone knows, when taking sediments sample with sampling spoon, stick to the not landing automatically of inwall sediments of spoon, after sampling spoon is toppled over, must rinse with clear water, flushing will make sediments run off like this; And cleaning is not very convenient.
2. the size of sampling spoon volume is wayward, and sediments can be excessive unrestrained.In the process of sediments sampling, sample spoon volume should be greater than the once required volume of sediments amount of intercepting, if the too little sediments that will make of volume can be excessive unrestrained, causes analytical error.
Summary of the invention
In sediments sampling process, sampling sample spoon requires inner wall smooth, sediments to topple over easily, it is not very convenient cleaning, the size of sample spoon volume is controlled bad, the excessive unrestrained deficiency of sediments meeting, the purpose of this utility model is to provide a kind of gas stripping type sediments sampling thief, substitutes sampling spoon, can be used for the extraction of sediments sampling.
The purpose of this utility model can realize by following measures:
A gas stripping type sediments sampling thief, is comprised of net head, piston, cylindrical shell, cover and pull bar.On cylindrical shell, have volume scale, net head is equipped with in the bottom of cylindrical shell, and cover is equipped with in upper end, with the pull bar of handle, through cover, is connected with the piston in cylindrical shell.
The beneficial effect of advantage of the present utility model and generation is:
1, the utility model utilizes inflator and built-in piston push-pull rod to make gas stripping type sediments sampling thief, some shortcomings when overcoming traditional sample spoon and taking sediments, safety, accurate flexibly,, while avoiding taking sediments, dirty sediments spatters outward, reveals, and cause original representative sample loss water, affect the accuracy of measurement result.
2, the utility model is simple in structure, simple for production, cheap, extracts sediments sampling safe and reliable, simple and convenient.Specialized equipment while sampling as sediments, configuration, to each experiment sample collector, can be experimental implementation and provides convenience.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
1. net 2. piston 3. urceolus 4. cover 5. pull bar.
Embodiment
Below in conjunction with accompanying drawing, then the utility model is described in further detail:
As shown in Figure 1, a kind of gas stripping type sediments sampling thief, is comprised of net 1, piston 2, cylindrical shell 3, cover 4 and pull bar 5.On cylindrical shell 3, have volume scale, net 1 is equipped with in the bottom of cylindrical shell 3, and cover 4 is equipped with in upper end, with the pull bar 5 of handle, through cover 4, is connected with the piston 2 in cylindrical shell 3.
During sediments sampling, with a cylindrical shell 3 that holds sampling thief, sampling thief is inserted in sediments, another holds the handle of pull bar 5, upwards pull, piston 2 in cylindrical shell 3 moves up with pull bar 5, when piston 2 moves on to the volume scale of cylindrical shell 3 interior certain positions, minimizing along with cylinder internal gas pressure, sediments will be automatically enters the inside of cylindrical shell 3 through the mesh of net 1, then from sediments, extract cylindrical shell 3, promote pull bar 5 downwards, piston 2 in cylindrical shell 3 moves down with pull bar 5, sediments in discharge cylindrical shell 3 is in sampling container, whole operating process is fast steady, safe and reliable, avoid malfunction and cause that sediments spatters outward, cause original representative sample to run off.
