[0002] Near some heavy industrial areas, the quality of groundwater is usually detected to determine whether there is heavy pollution leakage in the surrounding area. Currently, during the groundwater detection process, it is necessary to first use equipment to sample the groundwater. In the current technology, the sampling process is relatively complex. It is necessary to first use excavation equipment on the ground to create an exploration well reaching a predetermined depth. When there is enough water seeping in the exploration well, then use extraction equipment to extract it.

[0026] In order to make the above objects, features and advantages of the present utility model more obvious and understandable, the following detailed description of the specific implementation manners of the present utility model will be given with reference to the accompanying drawings of the specification.

[0027] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Those skilled in the art can make similar generalizations without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0028] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure or characteristic that can be included in at least one implementation manner of the present utility model. The "in one embodiment" that appears in different places in this specification does not all refer to the same embodiment, nor is it an individual or alternative embodiment that is mutually exclusive with other embodiments.

[0029] Thirdly, the present utility model is described in detail in conjunction with the schematic diagrams. When describing the embodiments of the present utility model in detail, for the convenience of explanation, the cross-sectional views showing the device structure will be enlarged locally not in accordance with the general scale, and the schematic diagrams are only examples and should not limit the scope of protection of the present utility model herein. In addition, in actual production, three-dimensional spatial dimensions including length, width and depth should be included.

[0030] Referring to Figures 1-3 , which is the first embodiment of the present utility model. This embodiment provides a groundwater sampling device for environmental geological engineering, including an insertion part 1. The insertion part 1 is in the length direction and is used to be inserted vertically into the soil layer. In addition, the device further includes:

[0031] The water storage cavity 2 is arranged on the insertion part 1, and the number thereof is multiple, specifically configured according to the number of different soil layers to be measured. The multiple water storage cavities 2 are distributed along the length direction of the insertion part 1;

[0032] The through port 3 is arranged on the insertion part 1, and the number thereof corresponds to that of the water storage cavity 2. The water storage cavity 2 is kept in communication with the outside through the through port 3;

[0033] The interception part 4 is arranged at the through port 3, which is used for the flow of water to pass through, and at the same time can block and intercept the soil. For example, the interception part 4 can adopt structures such as cloth or woven net;

[0034] During the process of sampling different water sources by the utility model, by driving the insertion part 1 into the stratum, the multiple water storage cavities 2 are respectively located at different depth positions. When the water in the soil at different depths penetrates, it will pass through the corresponding interception part 4 and then enter the through port 3 to be stored in the water storage cavity 2, so that the multiple water storage cavities 2 respectively collect water sources at different depths underground;

[0035] The structure of the utility model is simple, the manufacturing cost is low, and there are not many steps in the sampling process. Moreover, it can simultaneously collect water sources at different depths. Compared with the current equipment, the utility model has stronger practicability and can better cooperate with the testers to carry out water quality sampling work in different outdoor areas.

[0036] Further, referring to Figures 1-5 , the insertion part 1 is columnar, and its bottom end is a pointed structure, which is beneficial to penetrate into the soil layer. The water storage cavity 2 is constructed inside the insertion part 1, so as not to easily interfere with the process of driving the insertion part 1 into the stratum.

[0037] Further, referring to Figures 2-6 , the utility model further includes a fixing frame 5. The fixing frame 5 is detachably connected to the insertion part 1. When the fixing frame 5 and the insertion part 1 are assembled, the interception part 4 is clamped, so that the interception part 4 can be replaced, thereby improving the practical effect of the utility model.

[0038] Further, referring to Figure 4 and Figure 5 , a clamping groove 6 is arranged on the periphery of the through port 3. The fixing frame 5 and the clamping groove 6 are in plug-in fit, so as to achieve the detachable effect, which is convenient for the fixing frame 5 to be quickly removed and clamped on the insertion part 1.

[0039] Further, referring to Figure 4 and Figure 5 , when the fixing frame 5 is clamped in the clamping groove 6, the periphery of the interception part 4 will also be pressed tightly in the clamping groove 6 under the wrapping of the fixing frame 5, thereby improving the firmness and stability of the interception part 4 during installation.

[0040] Further, see Figure 4 and Figure 5 A blocking portion 7 is also provided in the through opening 3. The blocking portion 7 may be a block-shaped or rod-shaped structure, which may be integrally formed with the insertion portion 1. The blocking portion 7 is located on one side of the intercepting portion 4, so that the intercepting portion 4 can maintain itself overlapped on the blocking portion 7 under the action of soil pressure, so as to play a supporting effect on the intercepting portion 4.

[0041] Further, see Figure 2 The insertion part 1 is constructed with protrusions 8 on its periphery, and the number of the protrusions 8 corresponds to the through opening 3. The protrusions 8 are located at the lower end of the through opening 3. When the insertion part 1 moves downward in the soil layer, the protrusions 8 can push the soil at the through opening 3 outward so that the soil will not be excessively pressed on the intercepting part 4, thereby helping to further protect the intercepting part 4.

[0042] Further, see Figure 3 The utility model also includes a pipeline 9, which is connected from the inside of the water storage chamber 2 to the top end of the insertion part 1. The number of pipelines 9 is consistent with the water storage chamber 2. Each water storage chamber 2 can correspond to a pipeline 9. The setting of the pipeline 9 makes it possible to directly use the equipment to extract the water source in the water storage chamber 2, thereby further improving the convenience.

[0043] It will be appreciated that in the development of any actual implementation, as in any engineering or design project, numerous implementation-specific decisions may be made. Such a development effort may be complex and time-consuming, but will be a routine task of design, fabrication, and production for those of ordinary skill having the benefit of this disclosure without undue experimentation.

[0044] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
