Technical Field

[0001] The utility model relates to the field of groundwater detection, in particular to a sampling device for groundwater detection. Background Art

[0002] With the progress of society, people's awareness of environmental protection has gradually increased, and many measures have been taken to protect groundwater. For example, groundwater testing is used to understand the distribution, quantity and quality of groundwater resources, providing a scientific basis for the management and rational use of water resources.

[0003] When testing groundwater, due to its deep location and small diameter of the excavated test point, the detection is more difficult than normal water resource detection. How to sample groundwater has always been a difficult problem in this field. Therefore, we need to design a detection device that is convenient for sampling groundwater to assist testers in sampling groundwater. Utility Model Content

[0025] To facilitate understanding of the present application, the present application will be described more fully below with reference to the accompanying drawings. The accompanying drawings provide embodiments of the present application. However, the present application may be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of the present application more thorough and comprehensive.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application pertains. The terms used herein in the specification of this application are for the purpose of describing specific embodiments only and are not intended to limit this application.

[0027] It will be understood that spatial relational terms such as "under," "beneath," "below," "under," "above," "above," etc., may be used herein to describe the relationship of an element or feature shown in the figures to other elements or features. It will be understood that in addition to the orientations shown in the figures, spatial relational terms also include different orientations of the device in use and operation. For example, if the device in the drawings is turned over, the element or feature described as "under" or "beneath" or "beneath" the other elements will be oriented as "above" the other elements or features. Thus, the exemplary terms "under" and "under" may include both upper and lower orientations. In addition, the device may also include alternative orientations (e.g., rotated 90 degrees or other orientations), and the spatial descriptors used herein are interpreted accordingly.

[0028] It should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, or the orientations or positional relationships in which the technical product is usually placed when in use. They are only for the convenience of describing the present technology and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present technology. In addition, "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. Therefore, the terms "first", "second", "third", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance. In the description of the present utility model, unless otherwise specified, "multiple" means two or more.

[0029] Furthermore, terms such as "horizontal," "vertical," and "overhanging" do not necessarily imply that a component must be absolutely horizontal or overhanging, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but rather that it can be slightly tilted.

[0030] In the description of this technology, it should also be noted that, unless otherwise specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood broadly. For example, they can refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this technology based on the specific circumstances.

[0034] The collecting portion 3 is set on the winding frame 1 and separated from the movable portion 4 first. After separation, the movable portion 4 is moved so that the movable portion 4 can be attached to the collecting portion 3 to complete the sampling work.

[0035] See also Figure 2 and Figure 3 In this embodiment, the support tube 202 is fixedly mounted on the support rod 201 , and one end of the spring 203 is fixedly mounted on the top of the support tube 202 and is also mounted on the support rod 201 .

[0037] A drain valve 303 is provided on the receiving member 302 so that after the water sampling work is completed, the drain valve 303 can be opened to carry out sampling.

[0038] See also Figure 3 and Figure 4 The movable portion 4 of this embodiment includes a movable cylinder 401 , a connecting cylinder 402 and a card slot 403 . The movable cylinder 401 is fixedly connected to the connecting cylinder 402 , and the card slot 403 is provided on the side wall of the connecting cylinder 402 .

[0040] The fixing rod 502 is inserted into the slot 403 to fix the movable part 4, so that the movable cylinder 401 and the receiving part 302 are in a separated state. After being immersed in groundwater, the movable cylinder 401 is loosened and allowed to slide and fit onto the receiving part 302 to complete the sampling work.

[0041] See also Figure 3 and Figure 4 In this embodiment, there are two fixing rods 502 , which are symmetrically distributed on both sides of the support rod 201 , and the bottoms of the two fixing rods 502 are designed to be outwardly expanded arcs.

[0042] The bottom of the fixing rod 502 is designed to be arc-shaped to expand outwards, so that the fixing rod 502 can be tightly engaged with the slot 403 , and it is also convenient to squeeze the fixing rod 502 so that the fixing rod 502 can be pulled out from the inside of the slot 403 to release the movable cylinder 401 .

[0046] After sliding, the movable cylinder 401 fits against the inner wall of the receiving part 302. At this time, part of the groundwater will be stored inside the movable cylinder 401 and the receiving part 302. After being taken out to the ground, the drain valve 303 is used to release the collected groundwater to complete the sampling work.
