Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing, it is described be explanation to the utility model without
It is to limit.
Specific embodiment is given below.
As depicted in figs. 1 and 2, a kind of deep water sampling equipment, the cylinder 4 including top end opening, 4 bottom end of cylinder offer row
Fluid apertures 12；4 inner wall of cylinder is fixed with limit plate 6, and limit plate 6 and 4 inner wall of cylinder are tightly connected；It wears at 6 center of limit plate
Equipped with guide rod 5；Guide rod 5 is connected with piston 8 compatible with 4 inner wall of cylinder, other end connection close to 12 one end of drainage hole
There is the first pulling force rope 1；The top of cylinder 4 is fixedly connected with the second pulling force rope 2；4 outer wall of cylinder offers injection port 7,
The height of injection port is lower than the height of limit plate 6, and 4 outer wall of cylinder is additionally provided with sinker 11, adds clump weight on sinker 11
10；The end face of piston 8 towards limit plate 6 opens up fluted, and guide rod 5 is connected with bottom portion of groove, limit plate 6 and piston 8 it
Between guide rod 5 on be also arranged with pre-compressed spring 9；One end of pre-compressed spring 9 is fixedly connected with bottom portion of groove, pre-compressed spring 9
The other end is fixedly connected with limit plate 6；When piston 8 is in the maximum height of stroke, the height of injection port 7 is pushed up lower than piston 8
The height at end.
To above-mentioned it should be noted that integrally connected by welding between cylinder 4 and limit plate 6, is realized simultaneously
Sealed connection between cylinder 4 and limit plate 6；6 center of limit plate is embedded with multiple O-ring seals, realizes guide rod 5 and limit
It is tightly connected between the plate 6 of position, guide rod 5 can be moved up and down relative to limit plate 6；Before sampling, the first pulling force rope 1 is lifted
During so that sampler is deep into water body, pre-compressed spring 9 is compressed, and piston 8 and limit plate 6 contact, while piston 8 is right
Injection port 7 is blocked, and water sample can not be entered inside cylinder 4 by injection port 7；When sampler is deep into certain depth, together
The first pulling force rope of Shi Songkai 1 drags tight second pulling force rope 2, and piston 8 is under the elastic force effect of pre-compressed spring 9 relative under cylinder 4
It moves, by the plugging action not by piston 8 at injection port 7, because containing only a small amount of air, piston between piston 8 and limit plate 6
During moving down, vacuum up between piston 8 and limit plate 6, water sample is inhaled into cylinder 4 by injection port 7；?
Entering the water sample in cylinder 4 from drainage hole 12 during sampler decline will be discharged outside cylinder 4 by piston 8；4 top of cylinder is set
There is ear shaped ring 3, the second pulling force rope 2 is fixedly connected on ear shaped ring 3；Ear shaped ring 3 and clump weight 10 11 are respectively to adopt with cylinder 4
With one-piece construction, the stability that ear shaped ring 3 and sinker 11 connect between cylinder 4 respectively ensure that.
To above-mentioned it should be further noted that sinker 11 is arranged in 4 bottom end of cylinder.The center of gravity of sampler drops
It is low, it avoids under the effect of fluid flowing under water and the collective effect of buoyancy, what sampler cannot be vertical is deep into underwater；
And then the water sample for requiring depth can not be acquired.The depth sampled as needed simultaneously installs a fixed number on sinker 11
The clump weight 10 of amount.
Further, as depicted in figs. 1 and 2, the bottom end of cylinder 4 is cone structure, and cone structure center offers drain
Hole 12 reduces in sampling apparatus sinking watching, the penetration resistance of sampling apparatus.
Further, as shown in figure 3, clump weight 10 uses modularization clump weight 10, modularization clump weight 10 is using use
The organization plan of half-ring, two panels are to be worked in coordination between one group, one group by trapezoid block and dovetail groove.Convenient for clump weight 10
Disassembly and installation, and then by the gravity of the quantity of installation of modular clump weight 10 control sampler, keep sampler smooth
The respective depth for sinking to water body realizes the respective depth that sampling apparatus is accurately deep into water body.
Further, as depicted in figs. 1 and 2, the first pulling force rope 1 is labeled with scale.Sampler can be read and go deep into water
The depth of body.
Further, as depicted in figs. 1 and 2, the bottom end of cylinder 4 is additionally provided with sonar emitter 13, after entering in water
Sonar Signal is sent to the sonar reception device 15 on the water surface.
To above-mentioned it should be noted that in sampler during going deep into water body, the inevitably effect of undercurrent under water
Under, lateral offset can occur for sampler, when requiring the depth sampled deeper, even if the angle of offset is small, can also make reality
Biggish deviation occurs for border institute depth measurement degree and the depth of requirement, therefore is fixedly connected with sonar by bolt 14 in the bottom end of cylinder 4
Emitter 13, after sampler enters water body, sonar reception device 15 on the water surface receives Sonar Signal, can be with
The accurate depth for determining actual samples.
The specific implementation process of the utility model is as follows:
The first pulling force rope 1 is lifted, is deep into sampler in the water body of certain depth, then unclamps the first pulling force rope 1
While, lift the second pulling force rope 2, move down guide rod 5 and piston 8 with respect to cylinder 4, pre-compressed spring 9 stretches, when piston 8 not
When blocking injection port 7 again, water sample will be inhaled into cylinder 4.While sampling is completed then to unclamp the second pulling force rope 2, lifting first
Pulling force rope 1, by sampler lifting to the water surface.
Example given above is to realize that the utility model preferably example, the utility model is not limited to above-mentioned implementation
Example.Those skilled in the art according to the technical characteristic of technical solutions of the utility model made it is any it is nonessential addition,
