Specific embodiment
In the following, being described further in conjunction with attached drawing and specific embodiment to the present invention:
Pore water squeezer as Figure 1-Figure 2, including pressure head 11, outer cylinder 12 and pedestal 13, the lower end of pressure head 11 with
The sealing of outer cylinder 12 is slidably matched, and 12 upper end of outer cylinder is stretched out in the upper end of pressure head 11, and the upper end sealing of pedestal 13 is plugged under outer cylinder 12
End, 11 lower end of pressure head, 12 inner wall of outer cylinder and 13 upper end of pedestal are enclosed the accommodating chamber 14 of filling bottom sediment, pedestal 13
Bottom surface is provided with the slot 131 mating with 11 upper end of pressure head of pore water squeezer 10 described in another.
By the setting of slot 131, can separately the two neighboring pore water squeezer 10 be connected in a manner of concatenating and being stacked
It picks up and, quite convenient for assembly and disassembly, moreover, each pore water squeezer can be driven simultaneously after pressing to top pressure head 11
10 pressure head 11 squeezes the bottom sediment in accommodating chamber 14 simultaneously, and each 10 stress equalization of pore water squeezer, water outlet is unified, pressure
Squeezing obtained pore water will be collected by external pores water collector, so that its squeezing is highly efficient quickly, more it is crucial that by upper
Pressure head 11, pedestal 13 and the sealing of outer cylinder 12 are mating, its sealing effect can be made more preferable, effectively prevent bottom sediment mud
Husky and pore water, which leaks out, to be lost, while being also more conducive to efficiently and rapidly squeeze, and achievees the effect that easy to operate, reliable performance.
Wherein, cooperated by the inserting of the pressure head 11 of another pore water squeezer 10 and slot 131, each hole can be made
The concatenation of water squeezer 10 is more firm, is also more convenient for assembling and disassembling.Pore water after squeezing will retain in accommodating chamber 14, using outer
The pore water can be acquired and be taken by portion's hole water collector.
To be provided with runner 132 in pedestal 13, one end of runner 132 is penetrated through to the upper end of pedestal 13, runner convenient for being discharged
132 other end is penetrated through to the side wall of pedestal 13, and one end capping of the runner 132 has sintering felt 20, and the other end of runner 132 is used
It is connected in external pores water collector.Water outlet in accommodating chamber 14 will flow to 132 other end of runner through 132 one end of runner,
In, set sintering felt 20 can effectively filter the particle of bottom sediment, while provide enough strength supports again.
Preferably, runner 132 includes multiple split channels 1321 and the main channel for being respectively communicated with each split channel 1321
1322, split channel 1321 is located at the upper end of pedestal 13, and the upper end inlet ambient of split channel 1321 is provided with the first embedding mouth 133,
Felt 20 is sintered in the first embedding mouth 133, and the upper surface for being sintered felt 20 is flushed with the upper end of pedestal 13.Multiple split channels
1321 setting, more conducively Quick drainage, moreover, pass through the setting of the first embedding mouth 133, sintering 20 upper surface of felt and pedestal 13
Upper end flushes, and so can avoid sintering felt 20 by more frictional dissipations, positioning that can also be more stable to sintering felt 20.
To further strengthen filter effect, the upper end end face of the pedestal 13 of the present embodiment is covered with filter membrane 30, the filtering
The inner wall palette of film 30 and outer cylinder 12.It is covered since one end of runner 132 is sintered felt 20, sintering felt 20 can be protected
Filter membrane 30 is protected, prevents filter membrane 30 from being pressed by pressure head 11 and squeezing into one end of runner 132 and damaged.
Illustratively, the hole water collector of this example includes bushing and suction syringe, and the other end of runner 132 is provided with installation
Mouth 134, installing port 134 is for the hole water collector outside quick, convenient installation, in combination with members such as bushing, sealing ring, washers
Part further strengthens sealing.
For further lift-off seal effect, the lower end surface of pressure head 11 is covered with gasket 40, when the lower pressure-volume of pressure head 11
Receive bottom sediment in chamber 14 when, which can avoid bottom sediment and its pore water between pressure head 11 and outer cylinder 12
Subtle gap in leak out.
The gasket 40 of this example includes pedestal 41 and sheet rubber 42, the inner wall palette of pedestal 41 and outer cylinder 12, pedestal
41 upper surfaces are provided with the second embedding mouth 411, and the filling of sheet rubber 42 is embedded at the second embedding mouth 411.Pedestal 41 is made of nylon, sheet rubber
42 are made of vulcanized rubber.When extruding of the sheet rubber 42 by pressure head 11, compressive deformation expansion is generated, outwardly against positioned at the rubber
The pedestal 41 of 42 periphery of film, makes pedestal 41 and the closer combination of outer cylinder 12, achievees the effect that better seal.
The working principle of this pore water squeezer 10 is as follows:
Before work, first by the cleaning of all working component, drying, it is ensured that obtained sample is not by outer goods interference, pollution.It connects
The pedestal 13 of each pore water squeezer 10, outer cylinder 12 are assembled together.Filter membrane 30 is placed into, is played a role in filtering,
Then the bottom sediment silt sample that deep-sea acquires is put into accommodating chamber 14, places into gasket 40, be pressed into pressure head 11.Again
The pore water squeezer 10 respectively combined access external hydraulic device presses to pressure head 11, silt template is squeezed, by silt sample
Pore water in this is separated with sample.And by the runner 132 in filter membrane 30, sintering felt 20 and pedestal 13, pore water is led
Out in external pores water collector.In this way, hole water sample can be acquired quickly and easily, working efficiency is greatly improved, and
Sample quality is high, is able to reflect truthful data after being able to detect.
It will be apparent to those skilled in the art that can make various other according to the above description of the technical scheme and ideas
Corresponding change and deformation, and all these changes and deformation all should belong to the protection scope of the claims in the present invention
Within.
