Description
Technical field
The utility model belongs to sample collection field of tool, and in particular to a kind of chemical analysis detection sampler.
Background technology
Chemical analysis detection generally comprises five key steps：The collection of sample, the preparation of sample and decomposition, interfering component
Separation, content measure and data processing, the collection of sample is first key step, is provided for subsequent detection engineering
The engineering of feasibility material；Contamination monitoring and research work for water systems such as rivers and lakes are included to benthal deposit
Chemical analysis, grab bucket-type dredger are the main tools for gathering water system surface deposit, and existing grab bucket-type dredger is all
Two lifting ropes are needed to use, a grab bucket uses when sinking to the bottom, and another uses when grab bucket is left the water,
Operate more complicated, and need certain skill, operation difficulty is also larger, it is necessary to make improvements.
The content of the invention
The purpose of this utility model is to solve above mentioned problem existing for existing grab bucket-type dredger, there is provided a kind of
Chemical analysis detection sampler, its technical scheme are as follows：
A kind of chemical analysis detection sampler, it includes a pair of grab buckets being hinged, on the jointed shaft of grab bucket
Hanging one is provided with, hanging two is provided with grab bucket, existing bottom sampler is substantially such structure, and some processes change
To enter, be also required to two lifting ropes during use connects a hanging respectively, wherein when a drawstring above carries, grab bucket under gravity
Open, when another drawstring above carries, grab bucket under gravity closes；This programme improves as follows：Connection one is hung in hanging one
Group, hang group and include one section of steel wire rope, steel column and two sections of steel wire ropes, hanging one is fixedly connected with one end of one section of steel wire rope, one section
The other end of steel wire rope is fixedly connected with one end of steel column, and the other end of steel column is fixedly connected with one end of two sections of steel wire ropes, and two
The other end of section steel wire rope is fixedly connected with connection ring, due to hanging one be be hinged axis connection, hung so hang group and to drive
One upwards when carrying, under gravity grab bucket closure；A sleeve pipe is set with group is hung, the internal diameter of sleeve pipe is more than the maximum for hanging group
Diameter, allow to hang group in sleeve pipe slidably, sleeve pipe is fixedly connected with hanging two, when carrying sleeve pipe two upwards, is grabbed bucket in weight
Power effect is lower to be opened, and a corresponding grab bucket open configuration is provided with steel column and stops the positioning pin that sleeve pipe glides, is being positioned
Under the barrier effect of pin, during upper lifting group grab bucket can keep open configuration；The position for positioning the balance center of gravity both sides of pin is
Non-equilibrium position of centre of gravity is rotatablely connected with steel column, that is, positions pin in a free state due to vertical under Action of Gravity Field, positioning
The width of pin is less than the diameter of steel column, and positioning pin loses the barrier effect to sleeve pipe under vertical state, and hanging group can be
In sleeve pipe slidably, now upper lifting group, grab bucket close；Aboard ship manually will positioning pin turn it is flat and using a lifting rope to
Upper lifting group, positioning pin stop sleeve pipe, and grab bucket is opened, and after the grab bucket of opening drops to the bottom, continue to put lifting rope, and steel column can be after
It is continuous sink, in order that positioning pin can freedom of entry state, to make that sleeve pipe stops sinking or subsidence velocity is less than steel column, institute
To be provided with buoyancy compartment on sleeve pipe, be the material that vacuum or filling proportion are less than water in buoyancy compartment, such as air, helium, bubble
The overall proportion of foam, wood etc., sleeve pipe and buoyancy compartment is equal to or slightly less than or the proportion slightly larger than water, sleeve pipe is suspended or is produced
Faint buoyancy extremely slowly sinks, and it is vertical after pin freedom to position, and loses barrier effect, now starts to receive lifting rope, hang group
Pulling force effect hanging one on, do not act on hanging two on, grab bucket closure, capture surface deposit.
The beneficial effects of the utility model are：The collection of surface deposit just only can be completed with a lifting rope, and is operated
Simply, it is adapted to popularity to use.

Embodiment：
Referring to figs. 1 to Fig. 5, a kind of chemical analysis detection sampler, it includes a pair of grab buckets 1 being hinged,
Hanging 1 is provided with the jointed shaft 1-1 of grab bucket 1, hanging 23 is provided with grab bucket 1, existing bottom sampler is substantially this
The structure of sample, some is also required to two lifting ropes by improving, during use and connects a hanging respectively, wherein a drawstring above carries
When, 1 opening of grabbing bucket under gravity, when another drawstring above carries, 1 closure of grabbing bucket under gravity；This programme improves such as
Under：Group 4 is hung in connection one in hanging 1, is hung group 4 and is included one section of steel wire rope 4-1, steel column 4-2 and two sections of steel wire rope 4-3, hangs
Hang 1 to be fixedly connected with one section of steel wire rope 4-1 one end, the one section of steel wire rope 4-1 other end is fixed with steel column 4-2 one end to be connected
Connect, the steel column 4-2 other end is fixedly connected with two sections of steel wire rope 4-3 one end, two sections of steel wire rope 4-3 other end and connection ring
4-4 is fixedly connected, because hanging one 2 be connected with jointed shaft 1-1, so when hanging group 4 and driving the hanging 1 to carry upwards, heavy
The lower closure of grab bucket 1 of power effect；A sleeve pipe 5 is set with group 4 is hung, the internal diameter of sleeve pipe 5 is more than the maximum gauge for hanging group 4, makes to hang
Group 4 can be in sleeve pipe 5 slidably, and sleeve pipe 5 is fixedly connected with hanging 23, and when carrying sleeve pipe 5 two upwards, grab bucket 1 is made in gravity
With lower opening, 1 open configuration of corresponding grab bucket is provided with steel column 4-2 and stops the positioning pin 6 that sleeve pipe 5 glides, fixed
Under the barrier effect of position pin 6, during upper lifting group 4 grab bucket 1 can keep open configuration；Position the balance center of gravity both sides of pin 6
Position is that non-equilibrium position of centre of gravity is rotatablely connected with steel column 4-2, that is, positions pin 6 in a free state because Action of Gravity Field is sagging
Vertically, the width for positioning pin 6 is less than steel column 4-2 diameter, and positioning pin 6 loses the stop to sleeve pipe 5 under vertical state
Effect, hanging group 4 can be in sleeve pipe 5 slidably, and now above lifting group 4, grab bucket 1 close；Pin 6 will be aboard ship positioned manually
Turn flat and utilize the upward lifting group 4 of a lifting rope, positioning pin 6 stops sleeve pipe 5, and grab bucket 1 is opened, and the grab bucket 1 of opening drops to
Behind the bottom, continue to put lifting rope, steel column 4-2 may proceed to, in order that positioning pin 6 can freedom of entry state, to make sleeve pipe 5
Stop sinking or subsidence velocity is less than steel column 4-2, so, buoyancy compartment 7 is provided with sleeve pipe 5, is vacuum or filling in buoyancy compartment 7
Fill the material that proportion is less than water, such as air, helium, foam, wood, the overall proportion of sleeve pipe 5 and buoyancy compartment 7 is equal to or smaller
In or slightly larger than water proportion, make sleeve pipe 5 suspend or produce faint buoyancy or extremely slowly sink, position the freedom of pin 6 after
Vertically, barrier effect is lost, now starts to receive lifting rope, the pulling force effect of group 4 is hung in hanging 1, does not act on hanging 23
On, the closure of grab bucket 1, capture surface deposit.
Preferably, elongated through hole is provided with steel column 4-2, positioning pin 6 is arranged in elongated through hole.
