Description
Technical field
The invention belongs to soil area sampling technique fields, and in particular to a kind of soil remediation soil sample collector.
Background technique
Soil petroleum pollution not only breaks up soil, and polluted-water and air, and pollutant can endanger by all means
Evil human health.Its place soil pollutant is accurately defined as current environmental problem very serious in oil pollution place
Boundary and contaminated earth volume play a significant role the work such as subsequent risk assessment, repairing and treating, are accurately defining it
It usually need to be by being detected to soil sample during the boundary of place soil pollutant and contaminated earth volume.
When at present to soil sample, manual sampling is generallyd use, this sampling mode has the disadvantage that sampling efficiency is low
Under, soil sample original structure destroys big in sampling process；Due to soil it is petroleum-polluted after, soil mobility is eager to excel one than general soil
A bit, may be inadequate due to soil and sampler frictional force during being detached after the completion of soil sample sampling, and soil sample disengaging occurs
The case where, manual sampling mode is not suitable for the soil sample work in oil pollution region.
Summary of the invention
The purpose of the present invention is to provide a kind of soil remediation soil sample collectors, pass through Mechanical course soil sample
Journey, effectively improves sampling efficiency, the soil sample of acquirement close to natural structure undisturbed soil sample, and soil sample detach during prevent soil
Sample disengaging happens.
The technical solution that the present invention is taken to achieve the above object are as follows: soil remediation soil sample collector, comprising:
Frame body,
Lifting assembly is equipped with and worm screw cooperation including the worm screw on frame body is arranged in horizontal plane on frame body
First sleeve and turbine for driving worm screw to move up and down,
Sampling assemble is arranged with horizontal plane, and sampling assemble is made rotating motion by lifting assembly driving and oscilaltion
The soil body is sampled,
Wherein, sampling assemble includes sampling cylinder, and sampling cylinder interior sets the sampling cavity of columnar hollow, samples cavity wall ring
Around memory alloy wire is laid with, memory alloy wire is linearly and is parallel to the central axis of sampling cylinder, memory alloy wire by
Heat can deformation be serrated.First sleeve inner wall has the screw thread cooperated with worm screw.Turbine is driven by the motor being mounted on frame body
It is dynamic.
The present invention is equipped with corresponding with worm tooth shape by being moved up and down using turbine drives worm screw in frame body on frame body
First sleeve realize worm screw moved up and down in frame body, and the connection of worm screw and sampling assemble by that can move up and down and rotate come
The lifting and rotary motion for realizing sampling assemble, use this mode to substitute manually to descend pressure or other manual types to the soil body
Sampling, firmly unevenly cause when being compared to manual sampling soil sample ambient pressure variation greatly, soil sample original structure destroy certainty
The case where increase, the present invention, which samples the soil body with rotation status oscilaltion using worm drive sampling assemble, can guarantee brill downwards
Take the soil body exert oneself and speed it is uniform, make sample Shi Tuzhong ambient pressure variation uniformly, avoid soil sample from being disturbed and destroyed, take
The undisturbed soil sample close to natural structure is obtained, and further in such a way that memory alloy wire is arranged in sampling cylinder internal cavity inner wall
Come increase sampling cylinder in soil sample and sampling cylinder bore frictional force and reduce soil sample mobility, the memorial alloy in sampling
Silk and the soil sample in sampling cylinder there is certain CONTACT WITH FRICTION can lead to memory alloy wire generation deformation and be serrated fill
Crack between each soil layer of acquired soil sample, and soil particle mobility is reduced, and memory alloy wire uses thermoelasticity horse
Family name's body Transformation Principle is made, and the memory alloy wire with original shape is being heated to transformation temperature or more, so that it may deformation is generated, when it
Restore original shape after cooling again.
Specifically, worm screw bottom end is connected with coaxial assembly, sampling cylinder end has the assembly with assembly grafting
Slot.Sampling cylinder outer wall spiral surrounding is provided with screw wing.Being realized by assembly as connector will sampling cylinder and snail
Connection between bar makes the rotary force of worm screw pass to sampling cylinder by assembly and realizes sampling cylinder rotation, to realize band
The cutter hub of dynamic sampling bottom of cylinder rotates to drill through to the soil body, is convenient for by the way that screw wing is arranged in sampling cylinder outer wall spiral surrounding
Sampling cylinder guides the sampling cylinder outer wall soil body to move up and make its loosening during downward driving using screw wing, drops
The influence that low sampling cylindrical outer is pressurized to sampling cylinder interior soil sample, and fit through using turbine and worm the lifting of worm screw
Drive the lifting of sampling cylinder, control sampling cylinder drills through depth, dirty accurately to define its place soil convenient for obtaining data
The boundary of dye object and contaminated earth volume.
Specifically, perforation in the middle part of worm screw, worm screw upper end is connected with electric heater, and electric heater is by being set to worm screw through hole
Interior heat conductive filament connect with assembly, and memory alloy wire extends on the cell wall of assembly slot.Assembly slot is tooth form slot, tool
There is tooth socket, memory alloy wire extends in tooth socket.The deformation quantity that can control memory alloy wire to generate by heating method, is sampling
During detaching after the completion, the soil sample to avoid sampling from obtaining answered during detaching its mobility and with sampling cylinder inner wall
Frictional property, which is stablized, causes soil sample to be disengaged to the not accurate situation appearance of data, will be hot by heat conductive filament by power adder before detaching
In amount conduction to assembly, and memory alloy wire is set and extends to the assembly for making it with heated condition on the cell wall for assembling slot
Contact conduction heat increases memory alloy wire deformation quantity and reinforces to the soil sample in sampling cylinder and reduce the flowing of its soil particle
Amount, it is ensured that obtain the undisturbed soil sample close to natural structure, and can also effectively promote assembly by the heating to assembly and take
The being completely embedded property of sample cylinder prevents sampling cylinder from loosening in rotation or lifting process, is tooth form by setting assembly slot
Slot has tooth socket, realizes that worm screw rotation drives assembly to rotate in the way of tooth form cooperation, and drive using the tooth form flank of tooth
Dynamic sampling cylinder rotation, realizes power transmitting.
Specifically, assembly is the corresponding tooth form of shape with the section of assembly slot, convenient for the transmitting of power, assembly is realized
The rotary force of worm screw is passed to sampling cylinder by body, is additionally provided between assembly and assembly slot for filling assembly and assembly
The assembly set in gap between slot, prevents from sampling cylinder in sampling process and generating loosening, circle bounce public affairs when sampling cylinder rotates
The soil sample structure that difference increase causes it internal generates destruction, and assembly set and assembly are metal, and is heat-conducting metal, such as
Copper, iron etc. conduct convenient for heat and improve the deformation quantity of memory alloy wire and be thermally deformed speed.
