Problems solved by technology

When sampling with a water pump, in addition to the difficulty of sampling through the ship's sounding pipe, even if it is possible to sample large-diameter water tanks, some conditions limit its use
First of all, the depth of the ballast water surface from the deck cannot exceed 8-10m (the height of an atmospheric water column), otherwise it is impossible to use a pump to sample, and the depth of the water surface in most water tanks exceeds 10m; secondly, it must be injected into the water pipe before sampling Fill the pipe with water so that the pump can extract the water, which cannot avoid contamination of the collected samples; finally, a power source (gasoline fuel, electric power) is necessary
In addition, the use of water pumps for sampling will have a crushing and destructive effect on larger organisms in the water
Other types of ballast water sample collectors have problems such as small one-time sampling volume (generally less than 300mL), long sampling time, inability to sample in layers, and inability to collect ballast water and sediment at the same time

Embodiment Construction

[0016] The following embodiments will further illustrate the present invention in conjunction with the accompanying drawings.

[0017] As shown in Figures 1-5, the present invention is mainly assembled from four independent parts of a one-way valve 1, a collection hose 2, a one-way valve group 3 and an air cylinder 5. One-way valve 1 is made up of valve body 10, sealing ball 11 and porous baffle 12, and sealing ball 11 is arranged in valve body 10, and porous baffle 12 is arranged in the port of valve body 10 at the front end of sealing ball 11, and one-way valve 1 is placed in the collection hose 2 and fixed therein. The one-way valve group 3 is composed of two one-way valves 1 (see FIG. 1 ) and a three-way connector 9 , and the ports of the one-way valves can be tightly combined with the scale collection hose 2 . The piston head 8 in the gas cylinder 5 is covered with a sealing ring 7 to form a piston, and is integrated with the piston rod 6. When the piston rod 6 is pulled...

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 [0001] The invention relates to a sample collection device, in particular to a collection device which is mainly used in ship ballast water and sediment samples, as well as layered water samples of rivers, lakes, shallow seas and other water bodies. Background technique [0002] The conventional collection of ship ballast water and sediments in the world is mainly through power pumps (gasoline pumps, electric pumps). When sampling with a water pump, in addition to the difficulty of sampling through the ship's sounding tube, even if it is possible to sample a large-caliber water tank, some conditions limit its use. First of all, the depth of the ballast water surface from the deck cannot exceed 8-10m (the height of an atmospheric water column), otherwise it is impossible to use a pump to sample, and the depth of the water surface in most water tanks exceeds 10m; secondly, it must be injected into the water pipe before sampling Fill the pipe with water so that...
