Description of the drawings
The preferred embodiment of the present invention is described in detail below in conjunction with attached drawing.In figure：
Fig. 1 shows the sectional view of sampling apparatus according to the present invention；
Fig. 2 shows the vertical view of the agitating unit of sampling apparatus according to the present invention.
In the accompanying drawings, identical component uses identical reference numeral.Attached drawing is not drawn according to actual ratio.
Specific implementation mode
Below in conjunction with attached drawing, the present invention will be further described.
Fig. 1 shows sampling apparatus 50 according to the present invention.As shown in Figure 1, including 1 and of container for storing sample
The container cover 2 of 1 sealed connection of container, at least one thief hatch 3 being arranged in container cover 2, for sealing adopting for thief hatch 3
Sample mouth sealing cover 4, and the thief hatch protection cap 5 at 3 end of thief hatch of container 1 is set, wherein on thief hatch sealing cover 4
It is provided with the through-hole 41 that can be connected to thief hatch 3, and setting can block through-hole 41 between thief hatch 3 and thief hatch sealing cover 4
The first gasket 8, thief hatch 3 and the setting of thief hatch sealing cover 4 be formed in the thief hatch protection cap 5 and container cover 2 it
Between chamber 7 in.Therefore, the protection to thief hatch 3 and thief hatch sealing cover 4 is realized by the way that thief hatch protection cap 5 is arranged, kept away
The caused thief hatch sealing cover 4 that collides with exempted from transportational process loosens gas leakage.Simultaneously in transportational process, sampling cartridge of being more convenient for
It sets 50 to stack, keeps the transport more convenient.
Sampling apparatus 50 further includes at least one agitating unit 6 for stirring sample being arranged in container 1.Stirring is single
Member 6 is movable to be arranged in container 1, convenient for being moved under oscillator effect.Therefore clay sample can be solved by agitating unit 6
The problem of product, mud sample and high saliferous sample are united in saturated brine, accelerates in sampling apparatus 50 that lighter hydrocarbons " reach between head space
Air-liquid (Gu) balance each other ", the analysis efficiency and analysis precision of lighter hydrocarbons measurement between head space are improved, and then improve lighter hydrocarbons survey between head space
Determine application effect of the technology in Oil And Gas Geochemical Exploration.
Preferably, agitating unit 6 includes discoid agitator disk 61, and through-hole 63 is arranged in agitator disk 61 in the axial direction, such as Fig. 2
It is shown.During the test oscillation of sampling apparatus 50, the stirring action to sample may be implemented in this agitating unit 6.Stirring is single
Member 6 further includes the agitating shaft 62 being arranged at 61 center of agitator disk, and agitating shaft 62 is not provided with if avoiding, agitator disk 61 be easy to by
The phenomenon that clay sample wraps up.
It should be noted that agitating unit 6 can also be embodied as other structures, for example, section is the cylindrical member of "+" word,
Or the gyrostat that section is diamond shape.
For example, agitating unit 6 can be made of makrolon.While completing stirring action, it can guarantee not in container 1
Wall causes great impact, and the inner wall and agitating unit 6 itself to protect container 1 are not worn.And not by water or supersaturation
The corrosion of sodium chloride solution does not react with the hydrocarbon gas in sample, to the accuracy of guarantee test result.
Thief hatch protection cap 5 and 2 detachable connection of container cover.Preferably, using threaded connection.For example, in container cover 2
It is upper to extend vertically out circumferential wall 21 away from container 1, external screw thread 22 is set on the outer wall of circumferential wall 21, and in thief hatch protection cap
The internal thread 51 that setting coordinates with external screw thread 22 on 5 inner wall.So as to which thief hatch protection cap 5 is easily connected to appearance
On device lid 2.And by this simple structure and chamber 7 is connected and composed, for accommodating thief hatch 3 and thief hatch sealing cover
