Description

Technical Field

[0001] This utility model provides a sampling device, belonging to the field of hydrogeological and environmental technology, and particularly relates to a sampling device for hydrogeological and environmental environments. Background Technology

[0002] Hydrogeology, also known as environmental geology, is a branch of geology that studies the distribution, movement, quantity, and quality of groundwater, as well as the relationship between groundwater and engineering structures and the environment. It provides a scientific basis for the rational development and utilization of water resources, engineering site selection, design, and construction. At the same time, it focuses on the impact of human activities on the geological environment, assesses and prevents geological disasters, protects the geological environment, and promotes the harmonious development of humans and nature.

[0003] Current methods for detecting groundwater conditions in hydrogeological and environmental environments primarily involve direct drilling and sampling in the area to be tested to obtain groundwater samples for laboratory analysis. While this method is relatively direct and convenient, it inevitably causes some damage to the geological structure of the area. Furthermore, since groundwater detection is a long-term and continuous process, frequent drilling and sampling not only hinders the continuation of subsequent detection work but also fails to achieve continuous, fixed-point monitoring of environmental changes at specific locations. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, this application provides a sampling device for hydrogeological environment, which solves the problems of traditional sampling methods being highly destructive to geological structures, inconvenient to sample, and unable to achieve long-term fixed-point monitoring.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a sampling device for hydrogeological environment, including a ground surface, and a sampling structure located inside the ground surface through a shielding cover. The sampling structure includes a sampling tube located inside the shielding cover, and a piston corresponding to itself is provided inside the sampling tube. The lower end of the piston is connected to a water inlet pipe through a one-way valve. The other end of the water inlet pipe is connected to a locking valve that is connected to itself. A water passage pipe connected to itself is provided on one side of the locking valve.

[0006] Preferably, the shielding cover is a conical shell, with a base stone placed inside the ground at the bottom of the shielding cover, and a sealing cap connected to the other end of the shielding cover via a hinge.

[0007] Preferably, the piston is movably connected to a pressing handle on the side opposite to the one-way valve via a fixed connecting rod, and the pressing handle and the sampling tube are provided with a apex support.

[0008] Preferably, the water pipe is placed in the water body to be sampled, and the water pipe is connected to a sealing shell through a T-shaped connecting pipe. The sealing shell is fitted outside the lock valve, and an arc-shaped connecting pipe is provided between the sealing shell and the water pipe.

[0009] Preferably, the end of the connecting pipe near the sealing shell is connected to a sealing element that is fixedly connected to the locking valve via a groove, and the end of the locking valve away from the sealing element is connected to a valve element via a connecting rod. The valve element is placed above the ground, and a corresponding fixing frame is fitted on the outside of the connecting rod. The fixing frame and the sealing shell are fixedly connected by bolts.

[0010] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0011] This invention features a sampling structure housed inside a shielding cover. The sampling structure, aided by a piston and a one-way valve, allows for manual introduction of the water sample from the inlet pipe into the outlet pipe, ultimately leading to the sampling tube for easy sampling. After sampling, the locking valve is closed to isolate the sampling structure from the water environment, minimizing human interference. Furthermore, the shielding cover not only clearly marks the sampling location but also protects the sampling structure, facilitating future continuous testing and sampling.

[0012] Other advantages, objectives and features of this invention will be set forth in part in the description which follows, and in part will be apparent to those skilled in the art from the following examination or study, or may be taught from the practice of this invention.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains; the terminology used herein in the description of this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention; the term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0025] like Figure 1 and Figure 2 As shown, a sampling device for hydrogeological environment includes a ground surface. A sampling structure 2 is connected to the ground surface via a shielding cover 1 and placed inside the shielding cover 1. The sampling structure 2 includes a sampling tube 21 placed inside the shielding cover 1. The sampling tube 21 has a piston 22 corresponding to itself inside. The lower end of the piston 22 is connected to a water inlet pipe 11 through a one-way valve 23. The other end of the water inlet pipe 11 is connected to a locking valve 12 that is connected to itself. A water passage pipe 13 connected to itself is provided on one side of the locking valve 12.

[0026] In this embodiment, the present invention uses a sampling structure 2 set inside the shielding cover 1. Through the mechanical cooperation of the piston 22 and the one-way valve 23, the target water is manually guided from the water inlet pipe 13 to the water outlet pipe 11, and finally collected in the sampling tube 21, facilitating sample collection. After sampling, the locking valve 12 is closed to isolate the sampling structure 2 from the aquatic environment, reducing the impact of external factors on the sampling area. Simultaneously, the shielding cover 1 not only clearly indicates the sampling location, but its design also protects the sampling structure 2, ensuring the convenience of long-term sustainable monitoring and sampling.

[0027] like Figure 3 and Figure 4As shown, the shielding cover 1 is a conical shell design, fixed to the ground below by a base stone. The other end of the shielding cover 1 is connected to a sealing cap via a hinged shaft. The piston 22, on the side opposite to the one-way valve 23, is movably connected to the pressing handle via a fixed connecting rod. A apex support is provided between the pressing handle and the sampling tube 21. The water pipe 13 is placed in the water to be sampled and connected to a sealing shell 15 via a T-shaped connecting pipe 14. The sealing shell 15 is fitted over the lock valve 12. An arc-shaped connecting pipe is provided between the sealing shell 15 and the water inlet pipe 11. The end of this connecting pipe near the sealing shell 14 is connected via a groove to a sealing element fixedly connected to the lock valve 12. The end of the lock valve 12 away from the sealing element is connected to a valve component via a connecting rod. The valve component is designed to be positioned above the ground for easy operation. A corresponding fixing frame 16 is fitted over the connecting rod, and the fixing frame 16 is fixedly connected to the sealing shell 14 via bolts.

[0028] In this embodiment, the sampling device is designed to allow for water sample collection without damaging the geological structure. The conical shield 1 provides stable support while protecting the sampling structure 2 from external environmental influences. By pressing the handle, the movement of the piston 22 can be effectively controlled, guiding the water sample through the one-way valve 23 into the sampling tube 21. After sampling, the locking valve 12 is closed by operating the valve components, thereby cutting off the connection between the sampling tube 21 and the aquatic environment, ensuring sample purity and the safety of the sampling process. The sealing performance of the entire device is enhanced by the sealing shell 15 and the sealing elements, ensuring reliability and stability during long-term monitoring.
