Technical field
The present invention relates to Dredging Fields, and sampler is measured more particularly to a kind of underwater mud scum.
Background technology
Water-depth measurement method is broadly divided into two kinds again, i.e. acoustic measurement and water stone roller measures.In acoustic measurement, high band sound wave
The upper interface of mud scum can be measured, and low-frequency range sound wave can penetrate Mud Layer, measure hardcore, can not accurately measure Mud Layer
Thickness, the corresponding mud scum thickness of especially certain mud scum unit weight.Water stone roller measures and can only generally measure interface under Mud Layer or refer in particular to
The interface of unique mud scum unit weight, since water stone roller measures, actually measure is that water is cut or polish jade with an emery wheel to the rope length between the water surface, due to underwater water
The reason of stream, the rope that water is cut or polish jade with an emery wheel cannot keep plumbness, therefore measurement rope length can have very big error.
The method of underwater acquisition mud sample is broadly divided into two kinds, i.e. the sampling of drilling rod formula and lifting rope sampling.Wherein drilling rod formula samples
What is mainly acquired is the soil layer mud sample under hard, rather than mud scum, and picking rate is slow, costly, and sampling operation procedure is complicated;
Sling type sampling can acquire rapidly mud scum, but the corresponding depth of acquisition mud scum can not be measured accurately.

Description of the drawings
Fig. 1 is that the underwater mud scum of the present invention measures the overall structure diagram of sampler;
Fig. 2 is that the underwater mud scum of the present invention measures the part-structure schematic diagram of sampler.
Specific implementation mode
In order to make those skilled in the art more fully understand technical scheme of the present invention, below in conjunction with the accompanying drawings and most
The present invention is described in further detail for good embodiment.
Fig. 1-2 shows that a kind of underwater mud scum measures sampler, including sampling unit and mud scum measuring unit;Described is floating
Mud measuring unit includes holder 15, water pressure gauge 17 and is arranged at intervals on from bottom to top more on the holder vertical direction
16 based on a gross pressure by measuring muddy water gross pressure.Gross pressure meter in the application uses soil pressure cell, water pressure gauge to use
Pore pressure gauge, wherein pore pressure gauge can be used for sounding the depth of the water.The water pressure gauge is arranged in the down tube
Upper end lateral location;Gross pressure meter described in bottom is concordant with the lower end of the down tube, the gross pressure meter of the top
It is concordant with the upper end of the down tube.
The sampling unit includes outer tube 5, is arranged in the outer tube inner tube 1 and described outer for being clamped
The clamping piece of pipe;The clamping piece include for lifting rope annulus 18, be symmetrical set setting in the annulus both sides
It is equipped with the link block 14 of card slot 19, is hinged on the hook 9 of the link block end and the pressure of the hook described in connection two
Piece 8;The annulus passes through the card slot;The hook is hinged by axis pin 10 with the tabletting;The tabletting
It is fixedly connected with inner tube connector 21;
The inner tube includes upper tube and down tube;The upper tube is connected and fixed with the inner tube connector spiral;
The down tube is provided with sample introduction of the opening for mud scum;Preferably, the opening is symmetricly set at left and right sides of down tube.It is excellent
Choosing, the length of the inner tube is 2 times of the length of the outer tube.
The outer tube upper end is provided with flange 7 for facilitating fixation of the hook to the outer tube.
The down tube lower end is provided with hemispherical sampling pipe pedestal 3.It is provided with rubber cushion on the sampling pipe pedestal
4.The outer tube lower end is provided with and the matched platen of the sampling pipe pedestal 6.
The operation principle of the application is:The present invention is actually subjected to based on sampling unit, around sampling unit according to measurement
Several gross pressure meters sought setting water pressure gauge and be spaced apart up and down.Due to water pressure gauge measure be water pressure, lead to
It crosses that hydraulic pressure is strong and the correspondence (pressure=unit weight × depth of water) of the depth of water, the accurate depth of water position of this water pressure gauge can be conversed
It sets.When sampler keeps perpendicular attitude, because the difference in height that sampling unit itself is arranged by water pressure gauge it is found that can be pushed away
The depth of water of calculation understands the water depth value corresponding to each position of sampling unit.
For sampling inner tube, for being connect with clamping piece, down tube is used to sample for setting top tube and down tube, wherein upper tube,
In the altitude range of down tube, according to different requirements, several gross pressure meters can be arranged.Gross pressure measurement is the total of the position
Pressure, due to known to the depth of water position of gross pressure meter, it is possible to according to the pressure difference meter of the two of different location gross pressure meters
Calculate mud scum average volume density between two earth pressure gauges.In this way according to the required precision of real work, different number is arranged
Gross pressure meter, accurately can calculate and draw Mud Layer mud scum unit weight graded figure and corresponding water depth value.Meanwhile it will
Inner tube is arranged to top tube and down tube, after can making sampling, avoids pressure difference.
Clamping piece is set in the upper end of outer tube, when entering water, the lifting rope on annulus stretches, and makes locked by hooks outer tube, until taking
Sample position, sets that there are two opposite almost can be used for sampling through the rectangular aperture of tube body up and down on the tube wall of down tube, samples
After, lifting rope is loosened, hook is made to discharge outer tube, then outer tube under the action of self-weight entangles the down tube of inner tube, closes interior
The rectangular aperture of pipe to obtain required mud sample, and ensures that mud sample keeps nature, is not disturbed.Sampling pipe pedestal,
Rubber cushion and outer tube lower end setting platen can enable outer tube be discharged on pedestal and reduce vibrations.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, various improvements and modifications may be made without departing from the principle of the present invention, these improvements and modifications are also answered
It is considered as protection scope of the present invention.
