Gear screw is stated on 2 section of disrance sleeve between annular convex platform 4 and second one-way valve 308, to outer tube 1
Annular convex platform 4 is limited.
The working principle of the present embodiment is as follows:
The sampler is assembled according to structure as shown in Figure 1 and is completed.When work, first plug 310 is removed, uses vacuscope
The space in water storehouse pillar 304 and filter screen support tube 306 is evacuated by second one-way valve 308, vacuumizes completion
After remove vacuscope, second one-way valve 308 by extraneous air and internal vacuum insulation, for prevent the sample taken below from this
In spill out, then with plug 310 by vacuum check valve outlet block.306 tail end of filter screen support tube is connected to oil cylinder or gas
On the piston rod of cylinder, then reaches inside the deposit below seawater, after reaching specified position, outer tube 1 is fixed,
Piston rod pushes other components other than outer tube 1 to continue to move down, when the limiting device 5 on disrance sleeve 2 encounters housing
When annular convex platform 4 on 1 inner hole of pipe, the stopping of disrance sleeve 2 travels forward, but the intracorporal sampling tube assembly 3 of 2 chamber of disrance sleeve after
Continuous to travel forward, pass through 306 side wall of filter screen support tube inside Sediment Pore Water and water storehouse pillar 304 first is unidirectional
Valve 307 is connected to, and since the pressure of extraneous pore water is greater than the vacuum pressure in water storehouse pillar 304, pore water can be automatic
Enter in water storehouse pillar 304 from the first check valve 307, the pore water pressure inside and outside water storehouse pillar 304 reaches balance
Afterwards, the first check valve 307 is automatically closed, and the pore water taken is enclosed in inside water storehouse pillar 304, and entire sampler exists
External pressure is to gradually decrease during rising recycling, so the first check valve of 306 side wall of filter screen support tube
307 will not be opened, and the sample taken inside water storehouse pillar 304 will not be lost or pollute.After sampler recycling in place, Ke Yitong
It crosses and opens cone 301 and plug 302 for the hole water sample taking-up in water storehouse pillar 304.
In the above process, since 304 inner space of water storehouse pillar is smaller, only need the short period that can make water storage
Pore water pressure reaches balance inside and outside storehouse pillar 304, will can entirely be taken by the piston rod that 306 tail portion of filter screen support tube connects
Sample device is lifted up, and realizes the recycling to entire sampler, and tube assembly 3 will be sampled in this course by, which not needing, restores to original
State effectively reduces operating procedure, while can guarantee sampling quality again.
The above is only the preferred embodiments of utility model, are not limited to utility model, for the skill of this field
For art personnel, utility model can have various modifications and variations.It is all utility model spirit and principle within, made
What modification, equivalent replacement, improvement etc., should be included within the protection scope of utility model.
