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, term " on ", D score, " top ", the orientation of the instruction such as " 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 imply signified device or element must have 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
Being to be fixedly connected, or be detachably connected, or it is integrally connected；Can be joined directly together, it is also possible to by middle matchmaker
Jie is indirectly connected to.For the ordinary skill in the art, can understand above-mentioned term in utility model with concrete condition
Concrete meaning.
As shown in figure 1, the utility model provide a kind of sediment load sampling device, the device include top cover 4, sampling container 1,
Spring 5, drawstring 3, handheld unit 2-1 and driver element, handheld unit 2-1 are connected with sampling container 1, are taken for hand-held movement
Sample container 1, sampling container 1 has water inlet, and top cover 4 is rotatably connected on sampling container 1 and can open or close water inlet,
Spring 5 is used to drive top cover 4 to close in water inlet, and the one end of drawstring 3 is connected with driver element, the other end and top cover 4 are connected, and drives
Unit is used to open top cover 4 by controlling drawstring 3 to move.
Thus, when sampling is needed, sampling container 1 is extend into specified water level depth.After after water surface calmness, start and drive
Unit makes the upward pulling force that drawstring 3 applies to top cover 4 be applied to top cover 4 more than the gravity and spring 5 of top cover 4 to pull drawstring 3
Plus downward active force, open top cover 4 so that muddy water along water inlet enter sampling container 1 in.When sampling is finished,
Driver element returns to original state, makes the upward pulling force that drawstring 3 applies to top cover 4 less than 5 pairs of tops of deadweight and spring of top cover 4
The downward active force that lid 4 applies, so that top cover 4 is closed, during avoiding taking out sampling container 1 from muddy water, in sampling container 1
It is mixed into the muddy water of other water level depths.
Preferably, in the sampling container 1, one end of spring 5 is connected spring 5 with top cover 4, the other end of spring 5 with take
Sample container 1 is connected.When top cover 4 is closed in water inlet, spring 5 is in extended state, and sampling container 1 can be avoided to be moved in muddy water
When dynamic, top cover 4 is washed open by current and causes sampling inaccurate.
In addition, also include shaft seat, shaft seat include the first blade that jointed shaft and sampling container 1 connect and with top
Second blade of the connection of lid 4, the first blade and the second blade are rotated with jointed shaft and are connected.
Further, spring 5 is torsionspring, and torsionspring is set on jointed shaft, and one end of torsionspring and the
The connection of one blade, the other end are connected with the second blade.So set and be advantageous in that, on the one hand, due to torsionspring be arranged on
The side of sampling container 1, torsionspring will not enter sampling container 1 and form interference to muddy water from water inlet；On the other hand, due to
Torsionspring is not immersed in the muddy water sample in sampling container 1, therefore does not interfere with the composition of muddy water sample.
Preferably, handheld unit 2-1 is detachably connected with sampling container 1, to choose different length according to the different depth of water
The handheld unit 2-1 of degree.
Preferably, the material of drawstring 3 is stainless steel, to avoid the corrosion fracture by muddy water long period of soaking of drawstring 3.
Preferably, the middle part of top cover 4 is swelled towards outside, after the completion of sampling, sampling container 1 is taken out from muddy water
When, resistance to water-flow can be reduced.
Preferably, the middle part of the bottom surface of sampling container 1 is swelled towards outside, during to sample, sampling container 1 is stretched into water
When middle, resistance to water-flow can be reduced.
Preferably, driver element is rope winding jib.When the water level of sample area is deeper, rope winding jib is can select, by rotating
Reel on rope winding jib, makes part drawstring 3 be wrapped on reel, to open top cover 4 by pulling drawstring 3.
In addition, driver element is in addition to it can be rope winding jib, can also be rotating bar 2-2, the middle part of rotating bar 2-2 with
Handheld unit 2-1 is hinged away from one end of sampling container 1, and wherein one end of rotating bar 2-2 is connected with drawstring 3.Work as sample area
When water level is less deep, rotating bar 2-2 is can select, by rotating rotating bar 2-2, make to be connected with one end of drawstring 3 on rotating bar 2-2
It is upturned, top cover 4 is opened to pull drawstring 3；When sampling is finished, rotating bar 2-2 is rotated according to rightabout, make rotation
One end that drawstring 3 is connected with bar 2-2 declines, so that top cover 4 is closed.
Finally it should be noted that：Above example is only used to illustrate the technical scheme of utility model, rather than its limitations；To the greatest extent
Pipe has been described in detail to utility model with reference to the foregoing embodiments, it will be understood by those within the art that：Its according to
