Abstract
A sampling device for taking the specimen of water ballast and deposit of ship, and the water specimens for different water layers in river, lake or sea is composed of a flexible speciman taking tube, a one-way valve in said flexible tube, a one-way valve assembly consisting of two one-way valves and a three-way, and an inflator connected to the air inlet of said three-way whose another two ways are connected to said one-way valves.
Description
Technical field
The present invention relates to a kind of sample collecting apparatus, especially relate to a kind of harvester that is mainly used in the layering water sample of water bodys such as ship ballast water and sediment sample and river, lake, shallow sea.
Background technology
Chang Gui ship ballast water and sedimental collection mainly are to obtain by power water pump (petrol feed pump, electric pump) extracting in the world.When carrying out sample collecting with water pump, except being difficult to be undertaken the sample collecting by the ship sounding pipe, even can sample to bigbore water tank, but some conditions also define its use.At first, the degree of depth of the ballasting water surface from the deck can not surpass 8～10m (height of water of an atmosphere) otherwise just can't take a sample with water pump, and the water surface degree of depth all surpasses 10m in most of water tank; Secondly, also must inject the water of full packages before the sampling in water pipe, so that water pump energy extracting water outlet, this way can't be avoided the pollution to collected specimens; At last, must dynamic source (Fuel Petroleum, power supply).In addition, utilize water pump sampling meeting that the bigger biology of the individuality in the water is had the pulverizing destructive effect.The ballast water water sampler of other type all exist disposable sampling quantity little (being generally less than 300mL), sampling time long, can't group sampling, can not gather problems such as ballast water and sediment simultaneously.
Summary of the invention
The present invention is directed to the shortcoming of existing ship ballast water and sediment collecting device, a kind of structure and ship ballast water and sediment collector simple to operate, that collection capacity is big, efficient is high are provided.
The present invention is provided with the collection flexible pipe, is used for collected specimens, gathers flexible pipe and is provided with scale;
Check valve is arranged at and gathers in the flexible pipe, and check valve preferably is fixed on the lower end of gathering in the flexible pipe;
Check valve assembly comprises 2 check valves and threeway connector, and 2 check valves are arranged at 2 straight-through interfaces of threeway connector respectively, and the outlet side of check valve assembly or air-breathing termination are gathered the upper end of flexible pipe;
Inflator, the valve of inflator connects the intake interface of threeway connector.
Check valve is provided with valve body, ball sealer and perforated baffle, and ball sealer is located in the valve body, and perforated baffle is located at the valve body port of ball sealer front end.
Compare with the sediment collecting device with existing ship ballast water, structure of the present invention is very simple, ballast water water body section, layering and big collection capacity of bottom sediment and high efficiency sampling can be realized, and the degree of depth of the water body in the height on deck and cabin of the water surface in the water tank can be disposablely measured.

In Fig. 1-5, being labeled as of each parts: 1 check valve, 2 scales are gathered flexible pipe, 3 ' check valve group, 4 valves, 5 inflators, 6 piston rods, 7 seal rings, 8 piston heads, 9 threeway connectors, 10 check valve body, 11 ball sealers, 12 perforated baffles.
The specific embodiment
Following examples will the invention will be further described in conjunction with the accompanying drawings.
Shown in Fig. 1-5, the present invention is mainly assembled by check valve 1, collection flexible pipe 2, check valve group 3 and 5 four individual components of inflator.Check valve 1 is made up of valve body 10, ball sealer 11 and perforated baffle 12, and ball sealer 11 is located in the valve body 10, and perforated baffle 12 is located in the port of valve body 10 of ball sealer 11 front ends, check valve 1 be positioned over gather in the flexible pipe 2 and fixing wherein.Check valve group 3 is combined by two check valves 1 (referring to Fig. 1) and threeway connector 9, and the check valve port can be gathered flexible pipe 2 with scale and combine closely.Be with seal ring 7 on the piston head 8 in the inflator 5 and form pistons, and fuse with piston rod 6, about during pulling piston rod 6, ambient atmos is sucked and is discharged by valve 4.Inflator 5 becomes the aspiration column that fills that has the inflation and the function of bleeding simultaneously after assembling with check valve group 3.
When gathering complete water layer section, as long as will have the scale collection flexible pipe 2 of check valve 1 is placed in the water body of setting-out cabin by the ship sounding pipe, under the hydraulic pressure effect, check valve 1 is opened water and is entered in the collection flexible pipe 2 of being with scale, and makes the inside and outside water surface unanimity of collection flexible pipe 2 pipes.When on carry when gathering flexible pipe 2, thereby inner pipe water pressure is closed check valve 1 adopt water sample, this process need not to use check valve group 3 and inflator 5 just can finish sampling.When gathering the unconventional and unrestrained setting-out bilge of flexible pipe 2 portion, the water surface can directly be measured in the degree of depth of water body in the setting-out cabin and the water tank from the height on deck in the position of gathering the water surface in flexible pipe 2 pipes according to scale.
When water sample is gathered in layering, the outlet side of check valve group 3 is connected with gathering flexible pipe 2, again inflator valve 4 is linked to each other with threeway connector 9, just can inflation in gathering flexible pipe 2, manage and still be in closed condition after interior high pressure makes check valve 1 put into water body.Place when arriving required collection water depth when gathering flexible pipe 2, separate check valve group 3 and gather flexible pipe 2, check valve 1 is opened immediately, and the water that layer is adopted by institute just enters in the collection flexible pipe 2 and adopts the score layer water sample.
When the sampling of big collection capacity, with the suction end of check valve group 3 with gather flexible pipe 2 and link to each other, connect threeway connector 9 again and bleed with valve 4, the negative pressure in the pipe can suck more water sample and enter in the collection flexible pipe 2.When the water surface in the cabin just can continuously be extracted water sample with inflator 5 from the height on deck during less than 8m.
When the collection sediment, at first the method with layering collection water sample makes collection flexible pipe 2 keep anticyclonic pressure, is put into setting-out bilge portion again, the sediment bottom separation collection flexible pipe 2 and check valve group 3 just can collect.
