Description

Technical Field

[0001] This utility model relates to the technical field of groundwater sampling equipment, specifically a groundwater sampling device for mining areas. Background Technology

[0002] During the development and production of mining areas, groundwater is an important water resource. Its water quality not only affects the stability of the surrounding ecological environment, but may also have potential impacts on human health. Therefore, it is crucial to regularly sample and monitor groundwater in mining areas.

[0003] Traditional groundwater sampling devices in mining areas have many problems in practical applications. On the one hand, most sampling devices have fixed structures and cannot be flexibly adjusted according to the actual sampling depth requirements. When it is necessary to collect groundwater at deeper levels, it is often necessary to change to sampling equipment of different specifications, which is cumbersome and inefficient, increasing sampling costs and time costs. On the other hand, traditional sampling devices have poor sealing and flow control performance, which can easily lead to water leakage and changes in water quality parameters due to contact with air during the sampling process, thus affecting the accuracy and reliability of the sampling data and making it difficult to meet the requirements for precise monitoring of groundwater in mining areas. In addition, the connection structure of some sampling devices is complex, and assembly and disassembly are inconvenient. In the complex working environment of field mining areas, this brings great inconvenience to the operation of staff and reduces the efficiency of sampling work.

[0004] In view of the problems existing in the traditional groundwater sampling devices in mining areas, this utility model aims to design a groundwater sampling device in mining areas that is flexible in structure, has good sealing performance, is easy to operate and has accurate sampling, so as to solve the shortcomings of the existing technology and meet the actual needs of groundwater sampling work in mining areas. Utility Model Content

[0005] This utility model mainly provides a groundwater sampling device for mining areas to solve the technical problems mentioned in the background art.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a groundwater sampling device for mining areas, including a sealing cap, a Belle tube, a bottom pipe, a bayonet, and a guide block. The bayonet is located at one end of the sealing cap and the Belle tube, and the guide block is located at one end of the bottom pipe and the end of the Belle tube away from the bayonet. The sealing cap includes an exhaust port and a one-way exhaust valve. The sealing cap is located at the end of the Belle tube away from the bayonet, and the end away from the bayonet is provided with an exhaust port, in which a one-way exhaust valve is embedded. The bottom pipe includes a quick connector and a one-way flow valve. The bottom pipe is located at the end of the Belle tube away from the sealing cap, and the quick connector is located on the outer wall of the bottom pipe. The one-way flow valve is also embedded in the bottom pipe.

[0007] Preferably, the Bayer tube has a segmented structure, and the bayonet has a small opening that is slightly larger than the guide block. When two Bayer tubes are connected, the end of one Bayer tube with the guide block and the end of the other Bayer tube with the bayonet cooperate with each other, and a scale is provided on the outside of the Bayer tube.

[0008] Preferably, the one-way exhaust valve is completely embedded inside the exhaust port, and the outer wall of the one-way exhaust valve is in contact with the inner wall of the exhaust port; the sealing cap is in a corresponding contact with the connecting end of the Bayer tube, and the sealing cap covers the port of the Bayer tube away from the bayonet.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: The Bayler tube adopts a segmented structure, and the number of sections can be flexibly increased or decreased through the cooperation of guide blocks and bayonets to meet the sampling needs of groundwater in mining areas at different depths. This eliminates the need to replace the entire sampling equipment, reducing sampling costs and improving work efficiency. Firstly, the Bayler tube has graduations on the outside, allowing staff to visually read the sampling volume and ensure accuracy. Secondly, the one-way vent valve and one-way flow guide valve effectively prevent air ingress and water sample backflow, ensuring the purity and representativeness of the water sample and improving the reliability of the sampling data. The one-way vent valve is fully embedded in the vent port and fits snugly against the inner wall of the vent port, and the sealing cap fits snugly against the connecting end of the Bayler tube. The one-way flow guide valve is fully embedded in the bottom pipe and fits snugly against the inner wall of the bottom pipe. This multi-point sealing design effectively prevents water sample leakage and ensures the sealing of the sampling process. All components are coaxially fixedly connected via guide blocks and bayonets, making assembly and disassembly convenient and quick. The quick-connect fittings facilitate connection to external pipelines, simplifying the sampling operation process. This is particularly suitable for the complex working environment of field mining areas, reducing the labor intensity of staff.

[0018] To facilitate understanding of this utility model, a more comprehensive description of the utility model will be given below with reference to the accompanying drawings, which show several embodiments of the utility model. However, the utility model can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, these embodiments are provided to make the disclosure of the utility model more thorough and comprehensive.

[0019] Please refer to the attached document carefully. Figure 1-4A groundwater sampling device for mining areas includes a sealing cap 1, a Belle tube 2, a bottom pipe 3, a bayonet 22, and a guide block 21. The bayonet 22 is located at the end of the sealing cap 1 and the Belle tube 2 away from the bottom pipe 3. The guide block 21 is located at one end of the bottom pipe 3 and the end of the Belle tube 2 away from the bayonet 22. The sealing cap 1 includes a vent 11 and a one-way vent valve 12, adopting a "sealing cap + one-way vent valve" structure. The sealing cap 1 is made of transparent polycarbonate material, which is impact-resistant and allows observation of the water level inside the pipe. Its diameter matches the pipe body. It is connected to the Belle tube 2 through the bayonet 22, effectively preventing it from falling off when lifted. The sealing cap 1 is located at the end of the Belle tube 2 away from the bayonet 22, and the end away from the bayonet 22 has a vent 11, in which a one-way vent valve 12 is embedded. This one-way vent valve 12 is a built-in silicone one-way vent valve, allowing only the water inside the pipe to escape. Air is expelled, preventing external air from entering. The bottom tube 3 includes a quick connector 31 and a one-way flow guide valve 32. The bottom tube 3 is located at the end of the Bayler tube 2 away from the sealing cap 1. The quick connector 31 is located on the outer wall of the bottom tube 3. The quick connector 31 on the outside of the one-way flow guide valve 32 at the bottom matches the sampling bottle and is connected to a silicone guide tube. The sampling bottle is a "brown glass bottle with a sealing cap," which is light-proof and can prevent the decomposition of photosensitive substances. It is suitable for groundwater containing mineral processing agents in mining areas, and its cap has a pre-set interface. The bottom tube 3 also has a one-way flow guide valve 32 embedded in it. The one-way flow guide valve 32 is made of food-grade silicone material, which can resist the acid and alkali corrosion of groundwater in mining areas. The valve opening faces inward, allowing only water to flow in and preventing water from flowing out. The valve diameter matches the water inlet of the tube body to ensure that the water inflow rate is not lower than that of a traditional Bayler tube, thus avoiding a decrease in sampling efficiency.

[0020] For details, please refer to the attached document. Figure 1 The Bayler tube 2 has a segmented structure with a fixed length for each segment. The segments are connected via a quick-release connector, which locks the connection with a simple rotation, requiring no tools and taking ≤10 seconds. The bayonet 22 has a small opening slightly larger than the guide block 21. When two Bayler tubes 2 are connected, the end of one Bayler tube 2 with the guide block 21 engages with the end of the other Bayler tube 2 with the bayonet 22. The outer side of the Bayler tube 2 features clearly printed depth markings, with each marking continuous for easy real-time reading of the sampling depth. Furthermore, the material of the Bayler tube has been upgraded from traditional ordinary plastic to acid- and alkali-resistant polytetrafluoroethylene (PTFE), capable of withstanding pH environments from 2 to 12. Its smooth surface prevents contaminant adhesion, reducing cleaning difficulty. The outer side of the tube is wrapped with a scratch-resistant rubber sleeve to minimize damage from impacts with rocks, reducing the breakage rate.

[0021] For details, please refer to the attached document. Figure 3The one-way exhaust valve 12 is completely embedded inside the exhaust port 11, and the outer side wall of the one-way exhaust valve 12 is in contact with the inner side wall of the exhaust port 11; the sealing cover 1 is in a corresponding contact with the connecting end of the Beller tube 2, and the sealing cover 1 covers the port of the Beller tube 2 away from the bayonet 22.

[0022] For details, please refer to the attached document. Figure 4 The one-way flow valve 32 is completely embedded inside the bottom tube 3, and the outer wall of the one-way flow valve 32 is in contact with the inner wall of the bottom tube 3. The silicone of the one-way valve is added with an "anti-aging agent", extending its service life from 3 months to 1 year. The quick connector 31 is set vertically along the outer wall of the bottom tube 3, and the quick connector 31 is fixedly connected to the outer wall of the bottom tube 3. The snap connector is made of "304 stainless steel" to prevent rust.

[0023] For details, please refer to the attached document. Figure 1 The guide block 21 is fixedly connected to the end of the bottom tube 3, and the axis of the guide block 21 is collinear with the axis of the bottom tube 3; the guide block 21 is fixedly connected to the end of the Belle tube 2 away from the bayonet 22, and the axis of the guide block 21 is collinear with the axis of the Belle tube 2; the bayonet 22 is fixedly connected to the end of the sealing cap 1, and the axis of the bayonet 22 is collinear with the axis of the sealing cap 1; the bayonet 22 is fixedly connected to the end of the Belle tube 2 opposite to the end with the guide block 21. The axis of the device is collinear with the axis of the Beller tube 2; the device has a significant anti-interference effect. When the device is pulled up, the valve closes automatically, and the water in the tube does not backflow or shake, solving the problem of "water agitation caused by manual pulling"; at the same time, it has the advantage of depth control. In shallow mining areas, it is often necessary to accurately collect samples "0.5-2m below the water table". After optimization, the depth can be accurately controlled by "segment splicing + scale reading"; in addition, the segmented design distributes the lifting weight, and it can be easily operated manually to a depth of 15 meters.

[0024] The specific operation method of this utility model is as follows: When conducting groundwater sampling operations in the mining area, firstly, determine the required number of Baylor tube segments based on the target sampling depth, connect them sequentially, and rotate the bayonet 22 at the end of Baylor tube 2 to lock the guide block 21 of adjacent Baylor tubes into place with the bayonet 22, ensuring a secure connection of Baylor tube 2. Next, fix the sealing cap 1 to the top of the uppermost Baylor tube 2 using the bayonet 22, ensuring a sealed connection between the sealing cap 1 and Baylor tube 2. Then, connect one end of the silicone guide tube to the quick connector 31 on the outside of the one-way guide valve 32 at the bottom of Baylor tube 2, and the other end to the quick connector 31 on the sealing cap 1 of the sampling bottle, completing the assembly of the sampling device. Then, the operator holds the assembled sampling device and slowly lowers Baylor tube 2 to the groundwater sampling point in the mining area. According to the depth scale on the outside of Baylor tube 2, lower Baylor tube 2 to the target sampling depth and stop. The process of lowering the Belle tube 2 is as follows: During the lowering process, groundwater, under pressure, forces open the one-way flow valve 32 and enters the Belle tube 2. Air inside the Belle tube 2 is discharged through the one-way vent valve 12 on the sealing cap 1. After the Belle tube 2 is filled with groundwater, the operator slowly lifts the Belle tube 2. During the lifting process, the one-way flow valve 32 automatically closes to prevent water from flowing back out of the Belle tube 2. At the same time, the one-way vent valve 12 prevents external air from entering the Belle tube 2, keeping the water inside the Belle tube 2 stable and without shaking. After the Belle tube 2 is lifted to the ground, the one-way flow valve 32 is opened, and the groundwater inside the Belle tube 2 flows into the sampling bottle through the silicone guide tube. After sampling is completed, the connection between the silicone guide tube and the sampling bottle is disconnected, the sealing cap 1 of the sampling bottle is tightened, and the sampling bottle is marked. It can then be sent to the laboratory for testing and analysis.

Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvement made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, shall be within the protection scope of the present invention.
