Abstract

The utility model discloses a sediment sample ware is applicable to the bed mud of waters such as gathering river, lake and ocean. The utility model discloses an is connected through the bearing between the big grab bucket and little grab bucket, big grab bucket and little grab bucket, the centre of the circular -arc bottom in big grab bucket is equipped with the fixed loop, and the centre of the circular -arc bottom in little grab bucket is equipped with the pulley, and the one end system of rope is on the fixed loop, and the pulley is walked around to the other end of rope is on linking up with with the bearing, the both ends of all alone chain fix respectively grab bucket greatly and the both sides of the later half cylindric hopper of little grab bucket incorporation in the middle of. The utility model provides a sample thief because the grab bucket joint close is not tight, and partial rivers run through the sample thief, bed mud in the direct impact sample thief causes the difficult problem that the bed mud runs off from the joint close, has reduced the number of dropouts of bed mud among the sampling process, has increased the bed mud quantity of once gathering, has improved sediment sample's work efficiency.

Description

A kind of sediment sampler

Technical field

The utility model relates to a kind of substrate sludge sampling equipment, especially can obtain the grab type sampling thief of the Sediments such as river, lake and ocean.

Background technology

At present, known grab type sediment sampler is made up of two symmetrical grab buckets, bearing, pulley, hook, rope and balancing weight block device.

Before gathering bed mud, utilize hook system to make two grab buckets be in open configuration, then sampling thief is put into water.When grab bucket touches bed mud, grab bucket is inserted in bed mud by sampling thief under gravity, and continue to transfer rope, hook system is unclamped automatically, then upwards ropes, and under the effect of rope, pulley and bearing, two grab buckets are closed up, thus collect bed mud.

When promoting sampling thief through water body, due to grab bucket joint close imprecision, part current run through sampling thief inside, and current directly impact bed mud in sampling thief, cause bed mud to run off from grab bucket joint close, especially when in the bed mud gathered, silt content is higher, bed mud number of dropouts is very large, even all run off, to such an extent as to it is inadequate once to collect bed mud quantity, even do not have, have impact on the work efficiency of substrate sludge sampling.

Summary of the invention

In order to overcome the existing sediment sampler deficiency that bed mud runs off in sampling process, the utility model provides a kind of sediment sampler, and this sampling thief can reduce the number of dropouts of bed mud sample in sampling process.

The utility model solves the technical scheme that its technical matters adopts: sampling thief two grab buckets be arranged to differ in size, grab bucket joint close is made to depart from the vertical center line of sampling thief, current are avoided directly to run through sampling thief up and down, change water (flow) direction in sampling thief, slow down current directly washing away bed mud, and bed mud is mainly contained in larger grab bucket, part bed mud is positioned at below sampling thief joint close place surface level, avoid directly washing away of current, so just reach the object reducing bed mud number of dropouts in sampling process, increase the quantity once gathering bed mud.

Concrete technical scheme of the present utility model is, the utility model comprises large grab bucket, little grab bucket, bearing, set collar, pulley, rope, hook, drag-line and rope chain, it is the hopper of semi-circular cylindrical after described large grab bucket and little grab bucket merge, the end face of large grab bucket and little grab bucket is all fan-shaped, and the fan angle of large grab bucket is greater than the fan angle of little grab bucket.Be connected by bearing between large grab bucket with little grab bucket, large grab bucket relatively rotates with the spaced winding bearing of little grab bucket.Centre bottom arc-shaped in large grab bucket is provided with set collar, and the centre bottom the arc-shaped in little grab bucket is provided with pulley.One end of rope ties up on set collar, and the other end of rope walks around pulley and bearing ties up on hook, and one end of drag-line ties up on hook.The two ends of rope chain are separately fixed at large grab bucket and little grab bucket merges in the middle of the both sides of rear semicircle tubular hopper.The both sides that large grab bucket and little grab bucket merge rear semicircle tubular hopper are arranged with balancing weight respectively, and two balancing weights are equal in weight.

The beneficial effects of the utility model are: the number of dropouts that can reduce bed mud in sampling thief in sampling process, improve the work efficiency of substrate sludge sampling; The structure of sampling thief is similar to existing product, only changes grab bucket size, is beneficial to manufacture; The operation of sampling thief is similar to existing product, is convenient to promote the use of.

Fig. 3 is the schematic diagram of the utility model open configuration.

In figure: 1. grab bucket greatly, 2. set collar, 3. little grab bucket, 4. pulley, 5. balancing weight, 6. rope chain, 7. bearing, 8. rope, 9. link up with, 10. drag-line.

Embodiment

As shown in Figure 1, 2, the utility model sediment sampler comprises large grab bucket 1 and little grab bucket 3, and be the hopper of semi-circular cylindrical after large grab bucket 1 and little grab bucket 3 merge, the end face of large grab bucket 1 and little grab bucket 3 is all fan-shaped, and large grab bucket 1 is connected by bearing 7 with between little grab bucket 3.One end of rope 8 ties up on set collar 2, the other end of rope 8 walks around pulley 4 and bearing 7 ties up on hook 9, drag-line 10 also ties up on hook 9, balancing weight 5 in two grab buckets is equal in weight, owing to being symmetrical arranged, when large grab bucket 1 and little grab bucket 3 are merged into semi-circular cylindrical hopper, two balancing weights 5 are positioned in same level.The two ends of rope chain 6 are separately fixed at large grab bucket 1 and little grab bucket 3 merges in the middle of the both sides of rear semicircle tubular hopper.Hook 9 comprises counterweight hook and rotation axis, and counterweight hook and rotation axis are rotationally connected, and described rope 8 and drag-line 10 are all on the rotating shaft, and one end of counterweight hook is hook-shaped, and the other end is provided with counterweight.

During sampling, as Fig. 3, hook 9 hooks rope chain 6, lift drag-line 10, and rope chain 6 makes sampling thief unsettled, by grab bucket greatly 1 and little grab bucket 3 open, by regulating hook 9 to hook the position on rope chain 6, the end opening of large grab bucket 1 and little grab bucket 3 is positioned in same level.

By drag-line 10, the sampling thief being in the state of dehiscing is put into water.After the end opening of grab bucket 1 and little grab bucket 3 greatly touches bed mud, under gravity, two grab buckets are inserted in bed muds.When sampling thief no longer sinks, continue to transfer drag-line 10 and make it be in relaxed state, now rope chain 6 and hook 9 automatically disengage, and then lift drag-line 10, by linking up with 9, rope 8, bearing 7, pulley 4 and set collar 2 by grab bucket greatly 1 and little grab bucket 3 close up, bed mud got by sampling thief.

Continue to promote drag-line 10, after sampling thief goes out the water surface, be put on stationary plane, put forward cable drag chains 6, by grab bucket greatly 1 and little grab bucket 3 open, take out bed mud in sampling thief.

So far a substrate sludge sampling is completed.
