The method for making of the utility model sample bucket is as follows:

Sample bucket divides a staving 1 and the bucket ends 2 two parts, and top staving 1 is made by bore Φ 3.45cm lightweight stainless-steel roll bucket, long 24.0cm, and end opening liner one high 0.8cm stainless steel coil 11 cuts out the internal thread of Φ 2.95cm in the circle; 2 make a call to the inlet opening 22 of a Φ 1.05cm by the solid stainless steel round billet of long 4.65cm at the bottom of the bucket of bottom, the external thread that cuts out Φ 2.95cm suitable for reading, top and the bottom are that staving 1 is connected together with the bucket ends 2 a usefulness screw thread is stubborn, " O " shape O-ring seal 23 on the junction is nested with again, see shown in Figure 1ly, the internal thread that gets out a Φ 0.2cm between 2 inner rings at the bottom of the bucket and inlet opening 22 is in order to the fixing valve of being made by sheet rubber 3.Like this, it is heavy that sample bucket just forms at the bottom of the bucket of bottom 2 stainless steel billet, increased the deadweight of sample bucket, solves the sample bucket floating problem that kicks the beam, and the structure of this lightness sensation in the upper and heaviness in the lower, also increased the stability when sample bucket is placed; Because the upper and lower of sample bucket is integral by stubborn the connecing of screw thread, can dismantle at any time again, be convenient to change easily-consumed products--valve 3.The long 28.65cm of whole ladle body, internal diameter Φ 3.45cm measures clear height 25.5cm, in contrast to Weight by Draft that existing inspection and quarantine system uses with port water-mass density meter (external diameter Φ 2.0cm, maximum measuring height 20.5cm from 0.998～1.025, length overall 24.5cm), stopped measurement space; Suspension ring 4 long 7.8cm, the bottom is fixed on from 1.3cm position, bung upper edge, movable clear height 6.5cm, and bung 5 areas that are placed on the bung are more bigger than bung, and the two ends serial connection is fixed on the suspension ring 4, can hold up when falling at suspension ring 4 to move freely, and does not influence use.The stay cord of folding and unfolding, the folding and unfolding pulley structure of employing fishing fishing gear, the stay cord that lifts sample bucket uses 0.5 pound of nylon wire, but load-bearing 4Kg above (whole ladle body connects the water that suspension ring is added bucketful, and gross weight is 0.62Kg), intensity is enough; The pulley 6 of folding and unfolding stay cord, its two fixing feet, 62 holdings are fixed on the handle of being changed a social system by fishing rod 7, the detachable replacing; Handle 7 hollows, interior pad sponge, long 32.0cm, internal diameter Φ 2.8cm, deduction two lid, clear height 28.0cm can built-in port water-mass density meter.The kit exquisiteness is small and exquisite, is easy to carry, and is easy to use, and neat and tidy for ease of maintenaince, suits the port water sampling needs of Weight by Draft work very much.

The using method of this cover instrument is:

1. close safety fastener on the pulley prevents the unexpected slippage of stay cord;

2. the left hand handle makes sample bucket place ship side outer unsettled, and the right hand is opened safety fastener, allows the sample bucket free-falling;

3. according to mark on the stay cord, judge when sample bucket arrives predetermined depth, use the hand friction pulley, stop to put stay cord;

4. the safety fastener that closes once more stops 1-2 kind second, shakes pulley then and upwards receives rope, mentions sample bucket;

5. sample bucket is put on the plane to lee, the suspension ring that fell take out densitometer, density measurement from handle;

6. survey careful degree, pouring drains, and packs up kit.

Experiment test

After the sample bucket was made, we verified the practical effect of this sample bucket with the time in about 1 year.

1, sample representation:

We test in tank earlier, and this sample bucket is put into water (it is high that the water surface is not higher than bucket) fast, guarantee end water inlet, about 2 seconds energy bucketfuls.

Then, can we verify this sample bucket, and port water displacement fast in staving in the sinking process in water? we fill blue water sample in bucket, method with above introduction makes the bucket freely falling body, put into the different degree of depth of water, pull then and check whether this blueness water sample is displaced? through experiment confirm repeatedly, as long as this bucket is put into below the water surface 2m, the former blue liquid in the bucket just can be displaced fully.

Then, we compare experiment in real work.One year over, we have done nearly 300 times experiment in the Bei Lungang marine site, get about about the 10 meters water sample of top layer water sample and the depth of water with this sample bucket and contrast, the port water of the 10 meters left and right sides depth of waters in experiment confirm logical sequence port, north is about with the difference of the density of surperficial port water: 0.0005-0.010kg/m3.

Above experimental result has confirmed that mentality of designing originally is correct, and the sample bucket of this structure can realize getting the purpose of the representative water sample of certain depth well.Through working practice more than a year, behind this sample bucket on probation, the ship is very sure to the representativeness of port water sampling, and is undoubted, and repeatedly proposes to buy the purpose of this sample bucket.

2, practical application:

Actual use more than a year proves that this cover port water sampling instrument is very practical.One-piece construction is small and exquisite, is easy to carry; Stay cord never took place and beats and connect phenomenon, beat and save and influence the thing of work efficiency in structure of tow line science, rationally; Kept the clean, clean and tidy of instrument, not dirty hand in the use; Protected densitometer effectively, since this sampling instrument was on probation, densitometric breakage rate declined to a great extent, and never took place owing to carry former thereby cause the incident of densitometer breakage; Keep in repair easyly, it is aging and leak to meet valve, as long as turn on sampler barrel simply, the screw of the secure valve of outwarding winding is changed a valve and just can be dealt with problems, and the iron piece of pulley is met seawater and corrosion when serious, as long as rotate moving sleeve simply, change a pulley just, very convenient.

Comprehensive evaluation

By repeatedly experimental verification, and several port evaluation department of office proves that to the situation of this sample bucket checking the development of this sample bucket is very successful.Everybody is consistent to think this sample bucket and kit thereof, practical, exquisite, small and exquisite, portable, easy care.This problem has solved the representative not enough difficult problem of the port water sampling that perplexs Weight by Draft work for a long time, and carry with practicality on many innovations are arranged, in actual sampling work, be subjected to the consistent favorable comment of establishment concerning foreign affairs such as ship, harbour affairs, for some contribution is made in the raising of industry technical merit, thereby set up inspection and quarantine mechanism at equipment and technical leading standing and image in Weight by Draft work, having very, the promotion and application of reality are worth.
