Adopting 6 lower part of mud tube top and adopting the seamless connection of 7 top of mud pipe with outer semicolumn is non-removable external structure, and outer semicolumn adopts mud pipe
7 bottoms are tip 11, and bracket 2 is equipped with handle 3；Interior semicolumn adopts 8 top of mud pipe and adopts mud tube top 6-1 and interior equipped with interior semicolumn
Semicolumn adopts mud pipe 8 and interior semicolumn to adopt mud tube top 6-1 seamless connection be that non-removable structure is placed in outer semicolumn and adopts mud
In pipe 7 (when specific manufacture, for example interior semicolumn can adopt to mud pipe 8 and interior semicolumn adopts mud tube top 6-1 integrally after seamless fixation,
Interior semicolumn adopts 8 lower end of mud pipe and tip 11 is made, and upper outer semicolumn is then covered outside it and adopts mud pipe 7, then outer semicolumn is adopted
7 top of mud pipe is seamlessly connected outer semicolumn again and adopts mud tube top 6, and outer semicolumn adopts 6 top of mud tube top connection outer tie rod 4, outer company
4 top of extension bar connects handle 3, then outer semicolumn is adopted 7 lower end of mud pipe, tip 11 is made), the connection control rotation of 5 upper end of inside connecting rod
Button 1,5 lower end of inside connecting rod, which passes through hollow bracket 2 and hollow outer tie rod 4 and passes through outer semicolumn, adopts mud tube top 6, into outer
Semicolumn is adopted in mud pipe 7 and (can be used with being placed in the interior semicolumn that outer semicolumn is adopted in mud pipe 7 and adopt the top mud tube top 6-1 and connect
Weld seamless fixation or the connection that is screwed, for example 5 lower end of inside connecting rod is equipped with external screw thread, interior semicolumn adopts mud tube top 6-1
Equipped with internal thread hole, the two is connected through a screw thread, and 5 lower end of inside connecting rod is connected to interior semicolumn as far as possible and adopts the center mud tube top 6-1
Place, semicolumn interior in this way are adopted the rotation of mud pipe 8 and can preferably be rotated with circular manner, so as to guarantee to rotate control handle well
1, so that interior semicolumn is adopted mud pipe 8 and is changed into and adopt 7 shape of mud pipe with outer semicolumn and be completely coincident, and in being easier to rotate into, produce
Semicolumn adopts mud pipe 8, so that two semicolumns is changed into class cylindric)；In addition, also can be used: rubber seal tape is located at outer semicolumn
It adopts mud pipe and interior semicolumn is adopted between mud pipe and is located at interior semicolumn and adopts in the outer side edges of mud pipe, so just by rubber seal tape
It can guarantee that outer semicolumn adopts mud pipe and interior semicolumn is adopted closed between mud pipe, water is just not easy to adopt mud pipe and interior half from outer semicolumn

Interior semicolumn adopts the rotation of mud pipe 8, and buckle plush copper 9-1 is located at 10 side of rubber seal tape, the middle part of mud pipe 8 is adopted set on interior semicolumn
On outside.Above-mentioned snap-in groove 9, the setting position for buckling plush copper 9-1 and mode adopt rotating into for mud pipe 8 not harm interior semicolumn
Outer semicolumn is adopted mud pipe 7 or is produced premised on outer semicolumn adopts mud pipe 7, it may be necessary to which snap-in groove 9 is formed around outer half
Column adopts the semi-annular slot of 7 inside middle portion of mud pipe, and buckle plush copper 9-1 in this way can be in the semi-ring of this inside middle portion of snap-in groove 9
Obstruction will not be formed by rotating into or producing in shape slot.
Wherein: outer semicolumn adopt mud pipe 7 and interior semicolumn adopt mud pipe 8 can compared be closely linked and (but to guarantee to turn
When dynamic control handle 1, semicolumn, which adopts mud pipe 8 and can rotate into outer semicolumn and adopt mud pipe 7 or produce outer semicolumn, to be adopted outside mud pipe 7, therefore
Retain necessary gap, this gap can adjust, reach by the rubber seal tape 10 of elasticity outer semicolumn adopt mud pipe 7 with
Interior semicolumn, which is adopted mud pipe 8 and can be compared, to be closely linked), the mud layer taken can according to need the quarter in conjunction with outer tie rod 4
Degree, takes to required position.The outer semicolumn that outer semicolumn adopts the tip 11 of 7 bottom of mud pipe and top connects adopts 6 quarter of mud tube top
Degree is 10 centimetres, and outer tie rod 4 scale in middle section is 20 centimetres.Intermediate outer tie rod 4 and inner connection tube 5 respectively with outer attached column
Shape adopts mud tube top 6 and interior semicolumn is adopted mud tube top 6-1 splicing and is tightly connected.
The device method of operation: rotation control handle 1 first can relatively well make up them by the rubber seal tape 10 of elasticity
Between gap, so that so that outer semicolumn is adopted mud pipe 7 and interior semicolumn and is adopted 8 shape of mud pipe is completely coincident that (i.e. two semicolumns are adopted
The inside and outside overlapping of mud pipe forms spade, is easier in insertion mud layer), then device is slowly goed deep into sink vertically, until outer half
The tip 11 that column adopts 7 bottom of mud pipe contacts mud layer bottom；Next can control handle 1, i.e., rotation control handle 1, interior company
Extension bar rotation, interior semicolumn adopt the rotation of mud pipe 8, are about horizontal mode rotations, and buckling plush copper 9-1 will not be very prominent, not shadow
Rotation is rung, until rotation buckle plush copper 9-1 is allowed to be transferred in snap-in groove 9 and be stuck in snap-in groove 9 just, because of sink
Not deep, sampler is discharged than very fast, and buckle plush copper 9-1 in this way can play temporarily fixed effect, and semicolumn interior in this way adopts mud pipe 8
It turns to and adopts mud pipe 7 with outer semicolumn and formed similar cylindric and mud layer is acquired into income cylindrical adopt in mud pipe 8, complete primary
Simulation.According to outer tie rod 4 and mud pipe can be adopted, ratio reduced scale be carried out in conjunction with the depth of sink mud layer and water layer, by measuring water
The environmental change situation of slot mud layer and water layer, analysis sink adopt the actual conditions of mud disturbance water, and final result applies to practical reality
Test room sink and adopt dump analysis, for laboratory sink adopt mud provide conveniently.
Above-described case study on implementation, only the utility model compares one of preferred embodiment, ability
The usual variations and alternatives that the technical staff in domain carries out within the scope of the utility model implementer's case are included in practical
In novel protection scope.
