Embodiment
To make the purpose, technical scheme and advantage of utility model clearer, below in conjunction with the accompanying drawing in utility model,
Technical scheme in utility model is explicitly described, it is clear that described embodiment is utility model part implementation
Example, rather than whole embodiments.Based on the embodiment in utility model, those of ordinary skill in the art are not making creation
Property work under the premise of the every other embodiment that is obtained, belong to the scope of utility model protection.
In description of the present utility model, unless otherwise indicated, the orientation of the instruction such as term " on ", " under ", " top ", " bottom "
Or position relationship is, based on orientation shown in the drawings or position relationship, to be for only for ease of description the utility model and simplification is retouched
State, rather than indicate or imply that the device or element of meaning there must be specific orientation, with specific azimuth configuration and operation,
Therefore it is not intended that to limitation of the present utility model.
It should be noted that unless otherwise clearly defined and limited, term " connection " should be interpreted broadly, for example, can
To be to be fixedly connected or be detachably connected, or it is integrally connected；Can be joined directly together, middle matchmaker can also be passed through
Jie is indirectly connected to.For the ordinary skill in the art, it can understand above-mentioned term in utility model with concrete condition
Concrete meaning.
As shown in figure 1, the utility model provides a kind of sediment catcher, the sediment catcher includes top cover 1, sampling and held
Device 2, spring 3, the first drawstring 4 and assembly pulley, sampling container 2 have water inlet, and top cover 1 is rotatably connected on sampling container 2
And water inlet can be opened or close, spring 3 is used to drive top cover 1 to close in water inlet, and the first drawstring 4 is connected with top cover 1, sliding
Wheel group is connected with sampling container 2, for moving sampling container 2.
Thus, when needing deep water sampling, sampling container 2 is transferred to specified water level depth by assembly pulley.Treat the water surface
After calmness, the first drawstring 4 is pulled to open top cover 1, so that muddy water enters in sampling container 2 along water inlet.When sampling is completed
Afterwards, the first drawstring 4 is unclamped, top cover 1 is just closed in the presence of self gravitation and the elastic force of spring 3, and then can be avoided from muddy water
When taking out sampling container 2, the muddy water of other water level depths is mixed into sampling container 2.Then, start assembly pulley to pull sampling to hold
Device 2, when the upward pulling force that assembly pulley applies to sampling container 2 is more than the weight of muddy water sample in sampling container 2 and sampling container 2
When, sampling container 2 can take out from muddy water.Because the presence of assembly pulley can not only stretch into sampling container 2 deeper water
It is sampled in domain, and the pulling force needed for pulling sampling container 2 can be far smaller than muddy water in sampling container 2 and sampling container 2
The weight of sample.
Preferably, spring 3 is in sampling container 2, and one end of spring 3 is connected with top cover 1, and the other end of spring 3 is with taking
Sample container 2 is connected.When top cover 1 is closed in water inlet, spring 3 is in extended state, can avoid in sampling container 2 in muddy water
When mobile, top cover 1 is washed open by current and causes sampling inaccurate.
In addition, also include shaft seat, shaft seat include jointed shaft, the first blade for being connected with sampling container 2 and with top
The second blade that lid 1 is connected, the first blade and the second blade are rotated with jointed shaft and are connected.
Further, spring 3 is torsionspring 3, and torsionspring 3 is set on jointed shaft, and one end of torsionspring 3 with
The connection of first blade, the other end are connected with the second blade.So set and be advantageous in that：On the one hand, because torsionspring 3 is set
In the side of sampling container 2, torsionspring 3 will not enter the formation of sampling container 2 from water inlet to muddy water and interfere；On the other hand,
Because torsionspring 3 is not immersed in the muddy water sample in sampling container 2, therefore the composition of muddy water sample is not interfered with.
Preferably, the middle part of the middle part of top cover 1 and/or the bottom surface of sampling container 2 is swelled towards outside, during to sample,
Resistance to water-flow can be reduced during sampling container 2 is stretched into water；Or after the completion of sampling, sampling container 2 is taken out from muddy water
When reduce resistance to water-flow.The shape of the protuberance can be, but not limited to be cone, pyramid or hemispherical etc., as long as can reduce
Resistance to water-flow.
In addition, also including driver element, one end of the first drawstring 4 is connected with driver element, the other end and top cover 1 are connected.
Wherein, assembly pulley includes support 6-4, the second drawstring 6-1 and the movable pulley linked together by the second drawstring 6-1
6-3 and fixed pulley 6-2, support 6-4 are fixed on the ground, and movable pulley 6-3 is connected with sampling container 2, the second drawstring 6-1 one end
It is connected with support 6-4, the other end is used for hand-held pulling sampling container 2.Because movable pulley 6-3 side connects the second drawstring 6-1
Fixing end, the opposite side movable end that passes through fixed pulley 6-2 the second drawstrings of connection 6-1.Therefore, when the second drawstring 6-1 of pulling takes
When going out sampling container 2, the pulling force that the second drawstring 6-1 is subject to is only the weight of muddy water sample in the gravity and sampling container 2 of sampling container 2
The half made a concerted effort of power.
Preferably, fixed pulley 6-2 and/or movable pulley 6-3 quantity are multiple, further to reduce the second drawstring 6-1
Take out the pulling force needed for sampling container 2.
Preferably, driver element is rope winding jib.When the water level chin-deep of sample area, rope winding jib is can select, by rotating
Reel on rope winding jib, makes the first drawstring of part 4 be wrapped on reel, with by pulling the first drawstring 4 to open top cover 1.
In addition, driver element is in addition to it can be rope winding jib, support bar 5-2 and rotating bar 5-1 combination can also be
Structure, wherein rotating bar 5-1 middle part are hinged with support bar 5-2, and rotating bar 5-1 wherein one end is connected with the first drawstring 4.When
When water level is not especially deep, by rotating rotating bar 5-1 the one end for being connected with the first drawstring 4 on rotating bar 5-1 can be made to tilt upward
Rise, to pull the first drawstring 4 to open top cover 1；When sampling completion, rotating bar 5-1 is rotated according to opposite direction, makes rotating bar
One end that the first drawstring 4 is connected with 5-1 declines, so that the first drawstring 4 is in relaxed state and closes top cover 1.
Finally it should be noted that：Above example is only to the technical scheme for illustrating utility model, rather than its limitations；To the greatest extent
Utility model is described in detail with reference to the foregoing embodiments for pipe, it will be understood by those within the art that：Its according to
The technical scheme described in foregoing embodiments can so be modified, or which part technical characteristic is equally replaced
Change；And these modifications or replacement, the essence of appropriate technical solution is departed from each embodiment technical scheme of utility model
Spirit and scope.
