The present invention provides a liquid sampling device, comprising: a container having a cylindrical shape; the moving piece is arranged in the container and moves in the container under the driving of external force; a one-way valve disposed at a bottom end of the container; a connecting member connected to the moving member; a handle connected to the container. The utility model has the advantages of sampling far away from the shore, accurate depth sampling and the like.
Description
Technical Field
The utility model relates to sampling, in particular to a liquid sampling device.
Background
Along with the development of social economy, people's lives are gradually rich, people pay more and more attention to their living environments, especially water environment protection is concerned, and water body sampling is an important content of water environment protection and water environment scientific research. Different depths of water have different meanings to water quality researchers. When the existing water sampler is used for water sampling operation, the water sampler sinks to a water layer needing water sampling, the upper end or the lower end of the water sampler can be opened under the action of buoyancy, water around the water sampler enters the water sampler through the opening, and the water sampler is lifted out of the water surface through a rope of the water sampler and the like after water sampling is finished.
At present, the existing water collection can be carried out only on the bridge, the ship and the like.
SUMMERY OF THE UTILITY MODEL

a connecting member connected to the moving member;
a handle connected to the container.
Compared with the prior art, the utility model has the beneficial effects that:
1. the method can be carried out without being carried on a ship or a bridge;
standing on the shore of a sampling environment, putting the container into liquid by using a handle, and pulling the connecting piece by using external force so as to enable the moving piece to move in the container, wherein the liquid passes through the one-way valve and enters the container, thereby completing sampling;
the position of the sampling point is realized by utilizing the handle scalability, such as 3m, 5m and the like offshore;
the depth of the sampling point is realized by utilizing the buoyancy element and the connecting element, and the length of the connecting element is basically the depth of the sampling point.
2. The operation is convenient;
the distance between the sampling point and the shore is adjusted by utilizing the length of the handle, the depth of the sampling point is controlled by utilizing the connecting piece and the buoyancy piece, the operation is convenient, and the sampling is accurate.
Drawings
The disclosure of the present invention will become more readily understood with reference to the accompanying drawings. As is readily understood by those skilled in the art: these drawings are only for illustrating the technical solutions of the present invention and are not intended to limit the scope of the present invention. In the figure:
fig. 1 is a schematic structural view of a liquid sampling device according to embodiment 1 of the present invention.
Detailed Description
Fig. 1 and the following description depict alternative embodiments of the utility model to teach those skilled in the art how to make and reproduce the utility model. Some conventional aspects have been simplified or omitted for the purpose of explaining the technical solution of the present invention. Those skilled in the art will appreciate that variations or substitutions from these embodiments will be within the scope of the utility model. Those skilled in the art will appreciate that the features described below can be combined in various ways to form multiple variations of the utility model. Thus, the present invention is not limited to the following alternative embodiments, but is only limited by the claims and their equivalents.
Example 1:
fig. 1 is a schematic structural diagram of a liquid sampling device according to an embodiment of the present invention, and as shown in fig. 1, the liquid sampling device includes:
a container 11, the container 11 being cylindrical;
the moving piece 21 is arranged in the container 11, moves along the inner wall of the container 11 under the action of external force and keeps sealed with the inner wall;
a one-way valve 31, wherein the one-way valve 31 is arranged at the bottom end of the container 11, so that the liquid can only pass through the one-way valve 31 in one direction and enter the container 11;
a connecting member 61, wherein the connecting member 61 is connected with the moving member 21, so that an external force drives the moving member 21 through the connecting member 61;
a handle 41, said handle 41 being connected to said container 11 so as to extend the container 11 to a sampling point.
In order to prevent the moving member from tilting during movement, further, the liquid sampling device further includes:
a guide member 51, the guide member 51 being disposed at an upper side of the moving member 21, the connecting member 61 passing through the guide member.
In order to ensure that the moving member 21 remains coaxial with the container 11 during movement, the guide member 51 further has a guide hole 52 allowing the connecting member 61 to pass through, and the central axis of the guide hole 52 and the central axis of the container 11 are collinear.
In order to control the depth of the sampling point, further, the liquid sampling device further comprises:
the buoyancy member 71, the connecting member 61 is connected with the buoyancy member 71, and the buoyancy of the buoyancy member 71 is used for pulling the connecting member 61.
In order to adjust the distance from the sampling point to the shore, a telescopic sleeve is further adopted as the handle 41.
Example 2:
an example of the use of the liquid sampling device according to example 1 of the present invention in sewage sampling.
In this application example, as shown in fig. 1, the container 11 has a cylindrical structure; the moving member 21 is positioned in the container 11 and is in a disc shape, and the outer edge of the moving member and the inner wall of the container 11 are kept sealed; the guide member 51 is a cross bar, two ends of the cross bar are fixed at the upper end of the container 11, a through hole 52 is arranged at the center of the cross bar, and the central axis of the through hole 52 is collinear with the central axis of the container 11; the connecting piece 61 is connected with the moving piece 21 by adopting a connecting rope, penetrates through the central hole and is connected with the buoyancy piece 71; the buoyancy member 71 is a floating ball; the handle 41 is a telescopic tube.
The working mode of the liquid sampling device of the embodiment is as follows:
a sampling person grasps the handle 41 and extends the container 11 to a sampling point, and the distance from the sampling point to the shore is the length of the handle 41;
under the buoyancy action of the floating ball, the container 11 is suspended in the water, and the length of the connecting rope is slightly smaller than the depth of the sampling point;
rotating the handle 41 to increase the distance between the container 11 and the floating ball, so that the moving member 21 relatively moves in the container 11, and sewage at a sampling point passes through the one-way valve 31 and enters the container 11;
the container 11 is withdrawn, i.e. the sampling is completed.
