Description
Technical field
The invention belongs to hydrologic and silt observation technology field, it is adaptable to the waters such as river, lake, reservoir, river mouth and neritic area
River (sea) bed surface deposit is gathered, more particularly to a kind of sealable box bottom sampler.
Background technology
River (sea) bed surface deposit sampling be hydrologic and silt measurement, geologic survey, one of benthon environmental observation
Important process content.In order to improve observation and analysis precision, not only need to gather a number of sample, and require that sample is protected
Hold reset condition.
Conventional bottom sampler mainly has grab type, pull-type, conventional box bottom sampler etc. at present.Wherein, pull-type adopts mud
Device can not gather the original state sample of single-point；And though grab bucket-type dredger, conventional box bottom sampler can gather single-point sample, grab bucket
Formula bottom sampler is general important lighter, it is difficult to collect harder river bed deposit thing, sample effect is poor；And conventional box bottom sampler because
Its both sides perching knife is connected by the way of cross link, due to the presence of movable rod so that deposited with wall box perching knife side
In certain interval so that bottom sampler sealed bottom performance is not good, there is leak, the defect of leakage sand, it is difficult to ensure sediment sample
Integrality.
The content of the invention
The problem of present invention is in order to solve existing routine box bottom sampler poor sealing performance, proposes that one kind can effectively reduce case
The leak of body bottom, weakens current and silt sample in casing is scrubbed, realize what riverbed surface deposit original state sample was gathered
The box bottom sampler transmission is drawn using gear.
In order to achieve the above object, technical scheme is as follows：
A kind of use gear draws the box bottom sampler transmission, includes the casing 4 of lower openings, is arranged at the side of case two
The fixed frame 3 being connected with top, top formation fixed cross beam, with two fix bars with the side of casing two, it is characterised in that：It is described
A kind of use gear, which is drawn, also to be included the box bottom sampler of transmission to be arranged at the side of casing two and top activity box 2, is arranged at
The lower box, the gear perching knife 5 that simultaneously opening-closing case body can be rotated around mount point；
The activity box top is formed with moved cross beam, two sides and is formed with two motion bars, and two motion bar is socketed on institute
State in two fix bars, upper and lower side protrudes from two fix bar, the two motion bars bottom is formed with the cylindricality of longitudinal arrangement
Draw 2-4, the gear perching knife side is formed with arc perching knife 5-2, and opposite side is formed with can be with the drawing the sector being engaged
Gear 5-1.
Thus, can be by pulling the drawing on activity box, activity box cooperation sector gear, driving arc perching knife closure.
Box bottom sampler transmission is drawn according to heretofore described use gear, it is characterized in that：The moved cross beam
One middle side part be provided be arranged on circular shaft 2-3 on moved cross beam, can be to link up with hanging scroll of the 1-2 hook joints in the fixed cross beam
Elastic force unhook 1 on 3-1.
Use gear according to claim 2 draws the box bottom sampler transmission, it is characterized in that：The movable transverse
Beam side, which is provided with to break off relations for elastic force, provides the compression-spring device 2-2 of elastic force, and the compression-spring device includes the contracting spring body 2- for providing elastic force
The 2-1 and top 2-2-2 contacted that broken off relations with elastic force.
Thus, the sensitivity of unhook can be improved.The problem of not breaking off relations, can not sample is avoided the occurrence of, sampling success rate is high
Box bottom sampler transmission is drawn according to heretofore described use gear, it is characterized in that：The casing top
It is provided with retractable case lid 4-1.
Box bottom sampler transmission is drawn according to heretofore described use gear, it is characterized in that：The casing both sides
It is provided with lead case 4-2.
Box bottom sampler transmission is drawn according to heretofore described use gear, it is characterized in that：In the middle part of the casing
Spilled water hole 4-4, a diameter of 16-8mm of the spilled water hole are formed with top, aperture is sequentially reduced from the top down.
Thus, the overlying water of collection sample can be made from the slow overflow in casing both sides, it is to avoid overlying water is quick when casing is opened
The erosion damage to sample is flowed out, plays a part of protecting sample.
Box bottom sampler transmission is drawn according to heretofore described use gear, it is characterized in that：The arc perching knife
Inner surface is provided with sealing strip.
Box bottom sampler transmission is drawn according to heretofore described use gear, it is characterized in that：The casing and arc
Shape perching knife is brought into close contact, and gap is 0.3-1mm.
Thus, bottom sampler sealed bottom performance can be improved, so as to effectively reduce bottom sampler bottom leak to gathered sample
Scrub, disturb, it is ensured that sample structure is complete.
Box bottom sampler transmission is drawn according to heretofore described use gear, it is characterized in that, the activity box top
Portion is provided with handle 2-1.
Thus, boat-carrying release system can be connected.
Box bottom sampler transmission is drawn according to the use gear of the present invention, compared with conventional conventional bottom sampler, it is not only
Preferable sealing can be provided, be a kind of new hydrologic and silt scope while also can guarantee that higher sampling success rate, its
Advantage has：
(1) gear type perching knife is used, perching knife turned position and its gap between casing is accurately controlled, coordinates perching knife
The sealing strip that rear side is set, can make perching knife be brought into close contact casing when closing up, bottom sampler sealed bottom performance is good, so that effectively
Reduce bottom sampler bottom leak to the scrubbing of gathered sample, disturb, it is ensured that sample structure is complete.
(2) casing middle and upper part arrangement spilled water hole, up big and down small arrangement can make the overlying water of collection sample from casing both sides
Slow overflow, it is to avoid overlying water quickly to the erosion damage of sample, play a part of protecting sample by outflow when casing is opened.
(3) closable case lid is set in casing top, is prevented effectively from the inside and outside current of casing during bottom sampler is above carried and hands over
The dynamic influence to sample of the change of current.
(4) elastic force tripping gear is used, conventional bottom sampler gravity type tripping gear is solved because not taking off occurs in poor sensitivity
Hook, the problem of can not sample, sampling success rate is high.
