To keep the above objects, features, and advantages of the utility model more obvious and easy to understand, with reference to the accompanying drawing and have
Body embodiment is described in further detail the utility model.
As shown in Figure 1-3, the present embodiment provides a kind of device for the sampling of wetland soil, including sampler and sampling pipe
3, sampler includes sampler top cover 1, sampler cylinder 2 and capping 6, is from top to bottom provided with successively in sampler cylinder 2
Venting cavity 7, the capping of connection install room 8 and sampler inner cavity 9, are provided with the through-hole being in communication with the outside on 7 side wall of venting cavity
10, capping 6 is installed in capping installation room 8, passes through moving up and down in achievable venting cavity 7 and sampler for capping 6
Connection or closing between chamber 9, sampler top cover 1 are fixed on the upper end of sampler cylinder 2, sampling pipe 3 and sampler cylinder 2
Lower end forms and is detachably connected.
As shown in Fig. 2, capping 6 includes conus portion 61, cylindrical portion 62 and the bottom plate 63 from top to bottom set gradually, circular cone
Portion 61 and cylindrical portion 62 are an integral structure, and are formed and are detachably connected between cylindrical portion 62 and bottom plate 63, and capping is installed room 8 and wrapped
Include connection for limiting the conical cavity and the base plate chamber moved upwards for limiting bottom plate 63 that conus portion 61 moves downward, circular cone
The diameter of chamber and the circular hole of base plate chamber junction is greater than the diameter of cylindrical portion 62.
In this specific embodiment, the inner wall of 7 upper end of venting cavity is provided with screw thread, and sampler top cover 1 is threadedly connected to logical
In air cavity 7.In another embodiment, sampler top cover 1 is sheathed in venting cavity 7, by fastening screw by the side wall of venting cavity 7
It is fixedly connected with sampler top cover 1.
For the ease of carrying out rotating down pressing to sampler when sampling, it is provided with handle 4 on sampler top cover 1, handle 4 is worn
Oversampler top cover 1 and 4 both ends of handle stretching sampler top cover 1.
Sampler cylinder 2 includes that from top to bottom sequentially connected first cylinder and the second cylinder, the outer diameter of the first cylinder are big
In the outer diameter of the second cylinder, the first cylinder and the second cylinder are an integral structure.
It further include hose clamp 5 in order to which sampling pipe 3 is fixed, hose clamp 5 is used to sampling pipe 3 being fixed on the second cylinder.
In order to enable intake process and exhaust process are more uniform, through-hole 10 is set as four and is uniformly distributed in venting cavity
On 7 side wall.
It is inserted into wetland and easily facilitates operator's use in order to be conducive to sampling pipe 3,3 bottom end of sampling pipe is circumferentially provided with more
A opening.
Specifically used process are as follows: first sampler is assembled, capping 6 is installed in capping installation room 8, so
Sampler top cover 1 is fixedly connected with sampler cylinder 2 afterwards, then sampling pipe 3 is mounted on second of 2 lower end of sampler cylinder
External side is simultaneously fixed with hose clamp 5.
When sampling, so that sampler, is then pressed downward together by the lower end of sampler sampling pipe 3 and ground perpendicular contact
When along (or counterclockwise) direction rotating handles 4 clockwise, and then rotation is carried out to entire sampler and helps sampler quick
Reach desired depth.When needing to take out sampler outward, firmly handle 4, slowly propose soil for entire sampler, this
When due to negative pressure in sampler inner cavity 9 effect, sample 11 can be retained in inside the sampling pipe of lower end.
As shown in figure 4, capping 6 slides in conical cavity simultaneously naturally when sampler is in the original state before sampling
By the circular hole closing between conical cavity and base plate chamber.As shown in figure 5, when arrow direction pushes sampler along figure,
Initial gas pressure inside and outside sampler inner cavity 9 is identical, and 9 chamber air of sampler inner cavity by lower part due to being come in sampling process
Sample 11 be pressed through and open capping 6 and be discharged by the through-hole 10 of venting cavity 7.As shown in fig. 6, after stopping pushing, sampling
Air pressure inside and outside device inner cavity 9 restores consistent, and it is interior and by the circle between conical cavity and base plate chamber that capping 6 falls back to conical cavity naturally
Hole closing.As shown in fig. 7, when arrow direction above mentions sampler along figure, since sample 11 is under its gravity
Certain distance is slid downwards, and the volume of gas becomes larger so that pressure in sampler inner cavity 9 in sampler inner cavity 9 in the process
Reduce, capping 6 is squeezed the circular hole closed between conical cavity and base plate chamber by atmospheric pressure, in 9 cavity of sampler inner cavity
Negative pressuren zone is formed, suction-operated is generated to sample 11, the sample 11 of lower part is smoothly taken out.
Will entire sampler propose soil after can be laid flat, during being laid flat 11 surface layer of sample water flowing
Capping 6 is opened under percussion, so that sampler inner cavity 9 is connected to venting cavity 7, by the water on surface layer by the through-hole of venting cavity 7
10 release.
Sampling pipe 3 and sampler cylinder 2 can be separated, and then sample 11 be handled, sample by unclamping hose clamp 5
11 directly can carry away the whole preservation of progress by closing 3 both ends of sampling pipe, can also as former state slowly fall it from sampling pipe 3
In-situ treatment is carried out out.It such as needs to carry out sampling work next time, it is only necessary to repeat another sampling pipe 3 being mounted on sampler
The lower end of cylinder 2, and be fixed with hose clamp 5, and carry out sampling operation.
It can be seen that the device for the sampling of wetland soil of the present embodiment, achievable by moving up and down for capping 6
Connection or closing between venting cavity 7 and sampler inner cavity 9, capping 6 moves upwards so that venting cavity 7 during sampling pushes
It is connected to sampler inner cavity 9, so that sample 11 is smoothly acquired, when being lifted up sampler, sampler inner cavity 9 forms negative
Capping 6 is pressed in capping installation room 8 by pressure area, atmospheric pressure, and negative pressuren zone generates suction-operated to sample 11, so that sample
11 take out from underground intactly.The lower end of sampling pipe 3 and sampler cylinder 2, which is formed, to be detachably connected, different by replacement
The sampling pipe 3 of length, can the sample 11 to different depth be acquired, by the way that interchangeable sampling pipe 3 is arranged, can be improved
Working efficiency, the pedotheque of acquisition and storage different location different type wetland.
It applies specific case in this specification to be expounded the principles of the present invention and embodiment, the above reality
The explanation for applying example is merely used to help understand the method and its core concept of the utility model；Meanwhile for the general of this field
Technical staff, based on the idea of the present invention, there will be changes in the specific implementation manner and application range.To sum up institute
It states, the content of the present specification should not be construed as a limitation of the present invention.
