Description
Technical field
The present invention relates to a kind of for preventing the bed-sit sampler of turbulent water in high-velocity flow environment, belongs to hydraulic engineering
Technical field.
Background technique
Bed-sit sampling can provide necessary bottom sediment environment data for river, river mouth, the research of seashore water sand, be that science is ground
The necessary means studied carefully.Existing bed-sit sampler form is more various, and more there are commonly utilize impact in scientific research and engineer application
Power takes the clamshell sampler of surface layer sample, the bucket type sampler of semi-cylinder mounted in fish lead bottom, the sampling of dilatory bucker-type
Device, vertical type sampler etc..
Although current bed-sit sampling apparatus is more various, when wherein clamshell, bucket type, vertical type sampler bottom out for
Bottoming out position, to be required to sampler vertical with bed surface, so under the conditions of high-velocity flow, is acted on by high speed water jet impact, sampler is
The state for making bottom have the weights such as fish lead that balance is maintained also to be difficult to keep vertical bed surface, still more practical bed surface are often complicated more
Sample, especially bed ripples bed surface, swale transition region bed surface, the complexity of bed surface determine that sampler is difficult to keep hanging down with bed surface always
Directly, this be easy to cause the appearance of the case where invalid sampling.And though dilatory bucker-type sampler is of less demanding to sampler equilbrium position,
But scraper bowl is semi open type, and under high speed high-velocity flow environment, scraper bowl endosexine fine grained deposit is easy to be taken away by water flow, is made
It is roughened problem at sample silt.In conclusion needing a kind of convenience suitable under the conditions of high-velocity flow, disturbing efficiently and to sample
Move lesser bed-sit sampler.
Summary of the invention
The present invention provides a kind of for preventing the bed-sit of turbulent water from sampling in high-velocity flow environment in view of the above deficiencies
Device.
The present invention adopts the following technical scheme:
The bed-sit sampler of the present invention for being used in high-velocity flow environment prevent turbulent water, including at least one for adopting
The sampling cylinder of sample is equipped with tail-gate along an end face of the sampling cylinder axial direction, and sampling cylinder is to adopt relative to the other end of tail-gate
Sample mouth, connects hinge on thief hatch；Stack shell along sampling cylinder is equipped with anchor pole.
It is of the present invention for preventing the bed-sit sampler of turbulent water in high-velocity flow environment, on the sampling cylinder
Anchor pole be disposed adjacent to the barrel of thief hatch.
It is of the present invention for preventing the bed-sit sampler of turbulent water in high-velocity flow environment, on the thief hatch
Hinge extension be connected to adjustable fixing clamp.
The bed-sit sampler of the present invention for being used in high-velocity flow environment prevent turbulent water, the length of the hinge
Degree is adjustable.
The bed-sit sampler of the present invention for being used in high-velocity flow environment prevent turbulent water, the sampling cylinder
Cylinder is at cylindrical shape or square shape.
The bed-sit sampler of the present invention for being used in high-velocity flow environment prevent turbulent water, the tail-gate pass through
Hinge arrangement is connected with sampling cylinder.
It is of the present invention for preventing the bed-sit sampler of turbulent water in high-velocity flow environment, the sampling cylinder by
Steel material is made.
The bed-sit sampler of the present invention for being used in high-velocity flow environment prevent turbulent water, the hinge is by steel
Prepared material is made.
Beneficial effect
Provided by the present invention for preventing the bed-sit sampler of turbulent water in high-velocity flow environment, protect silt sample from height
Fast water impact causes the bed-sit sampler of sample disturbance roughening, solves the existing bed-sit sampling under high speed high-velocity flow environment
Device is difficult to constantly meet posture balancing requirement, the problem to sample by high-velocity flow disturbance protection deficiency.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention.
In figure 1 be 1 be anchor pole, 2 be hinge, 3 be sampling cylinder, 4 be tail-gate.
Specific embodiment
To keep purpose and the technical solution of the embodiment of the present invention clearer, below in conjunction with the attached of the embodiment of the present invention
Figure, is clearly and completely described the technical solution of the embodiment of the present invention.Obviously, described embodiment is of the invention
A part of the embodiment, instead of all the embodiments.Based on described the embodiment of the present invention, those of ordinary skill in the art
Every other embodiment obtained, shall fall within the protection scope of the present invention under the premise of being not necessarily to creative work.
It is a kind of for preventing the bed-sit sampler of turbulent water in high-velocity flow environment as shown in Figure 1:, include at least one
For the sampling cylinder 3 of sampling, it is equipped with tail-gate 4 along an axial end face of the sampling cylinder 3, sampling cylinder 3 is another relative to tail-gate 4
One end is thief hatch, connects hinge 2 on thief hatch；Stack shell along sampling cylinder 1 is equipped with anchor pole 1.Anchor pole 1 can play stabilization
The effect of 3 posture of sampling cylinder.
The extension of hinge 3 that anchor pole 1 on sampling cylinder 3 is disposed adjacent on the barrel thief hatch of thief hatch is connected to can
Adjust fixing clamp.Hinge 2 is connected with sampling cylinder 3, and the dragging sampling cylinder 3 in the case where pulling rope towing of hinge 2 advances, 1 injection of barrel anchor pole
Bed surface, sampling cylinder 3 tilt therewith, and nozzle injection bed surface, bed surface silt enters sampling cylinder 3 therewith；The sampling cylinder 3 is bed surface mud
Husky trap, as hinge 2 drags sampling cylinder 3, bed surface silt gradually pours into sampling cylinder 3；Then, hawser vertically lifts hinge 2,
So that sampling cylinder 3 is suggested bed surface in a vertical manner, and rise with hawser and promoted, sampling cylinder 3 is protected during this samples in cylinder
Silt is disturbed from external high-velocity flow；The tail-gate 4 is located at 3 bottom of sampling cylinder,
Tail-gate 4 is connected by hinge arrangement with sampling cylinder 3.When sampling cylinder 3 is promoted on research vessel, the work of tail-gate 4 is opened
Dynamic bolt, tail-gate 4 are separated with sampling cylinder 3 therewith, and the silt sample in sampling cylinder 3 automatically falls into mud sample under the effect of gravity and holds
Device.
The foregoing is only a preferred embodiment of the present invention, but scope of protection of the present invention is not limited thereto,
In the technical scope disclosed by the present invention, any changes or substitutions that can be easily thought of by anyone skilled in the art,
It should be covered by the protection scope of the present invention.Therefore, protection scope of the present invention should be with scope of protection of the claims
Subject to.
