Description

Depth water sample acquisition device in a kind of waters

Technical field

The utility model relates to depth water sample acquisition devices in field of environment protection equipment more particularly to a kind of waters.

Background technique

In the prior art, if to administer to water pollution, it is exactly water sampling that first, which needs the thing done, but existing Technology be by artificial timing acquiring water sample, it is very troublesome, be not easy to implement, and some water surface areas are excessive, there is a depthkeeping Degree, comprehensively and timing acquiring is almost difficult to realize, and pole is unfavorable for comprehensive improvement of water pollution, it would be highly desirable to solve.

Utility model content

To solve technical problem present in background technique, the utility model proposes depth water samplings in a kind of waters to fill It sets, the same position in waters may be implemented, disposable water sampling is carried out to different depth water sample.

The utility model proposes depth water sample acquisition devices in a kind of waters, comprising: water storage tube body is set pipe in tube body It is separated into the multiple partitions of multiple isolation wards in vivo, radial offer is in communication with the outside on the side wall of arbitrary first isolation ward Intake chamber, the inlet opening of connection the first isolation ward and intake chamber is offered on side wall, movable sealing has piston in intake chamber, Spring is equipped between piston and slot bottom,

When piston compression is less than first threshold, piston will block inlet opening to be in communication with the outside by intake chamber；

When piston compression meets or exceeds first threshold, compressed spring to slot bottom activity, is made the open water inlet of piston by piston Hole is in communication with the outside by intake chamber.

Preferably, the coefficient of elasticity of spring is directly proportional to S, and S is the distance between the first isolation ward and tube body upper head plate.

Preferably, inlet opening connects the upper spacer for being located proximate to the first isolation ward of the first isolation ward.

Preferably, bottom of the pipe is fixed with the metal weights of back taper.

The utility model has the advantages that the utility model disposably collects the water sample of different depth using pure automatic mode, structure is simple, And it is easily operated.

Detailed description of the invention

Fig. 1 is the utility model overall structure diagram.

Specific embodiment

As shown in Figure 1, the utility model proposes depth water sample acquisition devices in a kind of waters, comprising: water storage tube body 1, The multiple partitions 2 of multiple isolation wards will be separated by setting in tube body 1 in tube body 1, radial on the side wall of arbitrary first isolation ward 8 The intake chamber 3 being in communication with the outside is offered, the inlet opening 6 of connection the first isolation ward 8 and intake chamber 3, water inlet are offered on side wall Movable sealing has piston 4 in slot 3, and spring 5 is equipped between piston 4 and slot bottom,

When the compression of piston 4 is less than first threshold, piston 4 will block inlet opening 6 to be in communication with the outside by intake chamber 3；

When the compression of piston 4 meets or exceeds first threshold, compressed spring 5 to slot bottom activity, is kept piston 4 open by piston 4 Inlet opening 6 is in communication with the outside by intake chamber 3.

The coefficient of elasticity of spring 5 is directly proportional to S, and S is the distance between the first isolation ward 8 and 1 upper head plate of tube body.

Inlet opening 6 connects the partition 2 for being located proximate to the first isolation ward 8 of the first isolation ward 8.

1 lower end of tube body is fixed with the metal weights 7 of back taper.

The realization principle of the utility model is described as follows:

Tube body 1 is vertical into the water, since the coefficient of elasticity of spring 5 is directly proportional to S, and S is the first isolation ward 8 and pipe The distance between 1 upper head plate of body, wherein upper head plate is nearest from the water surface, as locating for first isolation ward 8 remoter from upper head plate Position, hydraulic pressure is higher, and the coefficient of elasticity of this floor spring 5 is also bigger, only reaches when the first isolation ward 8 sinks to hydraulic pressure One threshold value, the compression of piston 4 meet or exceed first threshold, and piston 4 could compress spring 5, and to slot bottom activity, make piston 4 Inlet opening 6 is opened by the connection between intake chamber 3 and the external world, at this point, water sample enters in tube body 1, hereby, it is achieved that working as tube body 1 enters in water, and when depth is not achieved, water sample can't be directly entered in the first isolation ward 8, until the first all isolation wards 8 It all reaches or more than predetermined depth, the water sample of different depth can just be entered in the first different isolation wards 8, to reach not The first same isolation ward 8 collects the purpose of the water sample of different depth, when by tube body 1 by taking out upwards in water, in spring 5 It under effect, is isolated from the outside automatically, water sample will not lose, and the utility model disposably collects different depths using pure automatic mode The water sample of degree, structure is simple, and easily operated.

The preferable specific embodiment of the above, only the utility model, but the protection scope of the utility model is not It is confined to this, anyone skilled in the art is within the technical scope disclosed by the utility model, practical according to this Novel technical solution and its utility model design are subject to equivalent substitution or change, should all cover the protection model in the utility model Within enclosing.
