Description

A hydrogeological groundwater and surface water fixed-depth and quantitative sampler Technical Field

[0001] This utility model relates to the field of surface water fixed-depth and quantitative samplers, and in particular to a groundwater and surface water fixed-depth and quantitative sampler for hydrogeology. Background Technology

[0002] Groundwater is widely developed and utilized due to its advantages such as stable water volume and good water quality. However, before development, it is usually necessary to sample and test the quality of the groundwater at the location. Groundwater samplers are usually used in the groundwater sampling process.

[0003] In existing technologies, such as the Chinese patent announcement CN207036483U entitled "A Groundwater and Surface Water Fixed-Depth and Quantitative Sampler for Hydrogeology", a hollow sampling tube is included. The sampling tube includes an inner tube and an outer tube that are rotatably arranged. The inner tube has a plurality of internal water inlet holes at equal intervals. The outer tube has an equal number of external water inlet holes in the gaps between the internal water inlet holes. This utility model allows the sampling tube to switch freely between a closed state and a connected state by rotating the inner tube or the outer tube relative to each other. No debris will enter the sampling tube during the process of insertion into the ground.

[0004] In existing technologies for groundwater sampling, the sampler needs to use a pipeline to collect and transport the water flow. This means that when the water flow is at a greater depth, a longer pipeline is required, which makes it inconvenient to collect materials for deep water flow.

[0005] Therefore, it is necessary to provide a hydrogeological groundwater and surface water sampler with fixed depth and quantity to solve the above-mentioned technical problems. Summary of the Invention

[0006] This utility model provides a hydrogeological groundwater and surface water fixed-depth and quantitative sampler, which solves the problem that the sampler needs to use a pipeline to collect and transport water flow, which requires a long pipeline when the water flow depth is large, thus making it inconvenient to collect deep water flow materials.

[0007] To solve the above-mentioned technical problems, this utility model provides a hydrogeological groundwater and surface water fixed-depth and quantitative sampler, including a collection bucket. A positioning frame is movably sleeved on the top of the collection bucket, and a positioning ring is fixedly connected to the top of the positioning frame. A pull rope is movably sleeved inside the positioning ring. A scale groove is opened on the front of the collection bucket, and a water inlet is opened at the bottom of the inner cavity of the collection bucket. A sealing plate is movably sleeved at the bottom of the inner cavity of the collection bucket, and a counterweight is fixedly connected to the bottom of the collection bucket. An auxiliary mechanism is set inside the collection bucket, a discharge mechanism is set on the side of the collection bucket, and a sealing mechanism is set on the top of the collection bucket.

[0008] Preferably, the front of the positioning frame is inverted U-shaped, and the positioning frame is located directly above the water inlet.

[0009] Preferably, the collection bucket is made of plexiglass and is located directly below the pull rope.

[0010] Preferably, the sealing plate is located directly above the water inlet, and the sealing plate is made of rubber.

[0011] Preferably, the counterweight is made of stainless steel and is parallel to the closing plate.

[0012] Preferably, the auxiliary mechanism includes a fixing frame, which is fixedly connected to the side of the inner wall of the collection bucket, and a thermometer is fixedly sleeved inside the fixing frame.

[0013] Preferably, the discharge mechanism includes a drain pipe, which is fixedly sleeved on the side of the collection bucket, with a flexible hose fixedly sleeved at one end of the drain pipe and a spring clip fixedly sleeved at the other end.

[0014] Preferably, the sealing mechanism includes a top cover, which is threaded onto the top of the collection bucket, and the top of the top cover has an exhaust hole.

[0015] Compared with related technologies, the hydrogeological groundwater and surface water fixed-depth and quantitative sampler provided by this utility model has the following beneficial effects:

[0016] This utility model provides a hydrogeological groundwater and surface water fixed-depth and quantitative sampler. By setting a positioning frame, when deep well water flow sampling is required, one end of the pull rope is fixed inside the positioning ring. At this time, the sampling bucket is dropped into the deep well, allowing water flow to enter the sampling bucket through the inlet. When the water flow sampling is finished, the pull rope is raised, which drives the sampling bucket to rise. When the pull rope is raised, the sealing plate closes the inlet, allowing the water flow to be extracted from the deep well. This avoids the inconvenience of collecting water through pipelines, thus bringing convenience to groundwater sampling.

[0017] By setting up a sealing plate, when water flow sampling is carried out, the water flow outside the sampling bucket impacts the sealing plate, causing the sealing plate to bend upwards, thereby opening the water inlet. When the water flow sampling ends, the water flow inside the sampling bucket squeezes the sealing plate in the opposite direction, thereby closing the water inlet. This achieves a one-way flow effect of water flow inside the sampling bucket, thus bringing convenience to water flow sampling. Attached Figure Description

Detailed Implementation

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Please refer to Figures 1, 2, 3, and 4. Figure 1 is a structural schematic diagram of a preferred embodiment of a hydrogeological groundwater and surface water fixed-depth and quantitative sampler provided by this utility model; Figure 2 is a cross-sectional view of the hydrogeological groundwater and surface water fixed-depth and quantitative sampler shown in Figure 1; Figure 3 is a bottom view of the hydrogeological groundwater and surface water fixed-depth and quantitative sampler shown in Figure 1; and Figure 4 is a top view of the hydrogeological groundwater and surface water fixed-depth and quantitative sampler shown in Figure 1. A hydrogeological groundwater and surface water sampler for fixed depth and quantity includes a sampling bucket 1, a positioning frame 2 movably connected to the top of the sampling bucket 1, a positioning ring 3 fixedly connected to the top of the positioning frame 2, a pull rope 4 movably connected inside the positioning ring 3, a scale groove 5 on the front of the sampling bucket 1, a water inlet 6 at the bottom of the inner cavity of the sampling bucket 1, a sealing plate 7 movably connected to the bottom of the inner cavity of the sampling bucket 1, a counterweight 8 fixedly connected to the bottom of the sampling bucket 1, an auxiliary mechanism 9 inside the sampling bucket 1, a discharge mechanism 10 on the side of the sampling bucket 1, and a sealing mechanism 11 on the top of the sampling bucket 1.

[0025] The positioning frame 2 has an inverted U-shaped front and is located directly above the inlet 6. By setting up the positioning frame 2, when deep well water sampling is required, one end of the pull rope 4 is fixed inside the positioning ring 3. At this time, the sampling bucket 1 is dropped into the deep well, allowing the water to enter the sampling bucket 1 through the inlet 6. When the water sampling is finished, the pull rope 4 is lifted, which causes the sampling bucket 1 to be lifted. The sealing plate 7 then seals the inlet 6, allowing the water to be extracted from the deep well. This avoids the inconvenience of water transport through pipelines and brings convenience to groundwater sampling.

[0026] The collection bucket 1 is made of plexiglass and is located directly below the pull rope 4. By setting up the collection bucket 1, when collecting water flow, staff can directly observe the water flow inside the collection bucket 1, thus facilitating the observation of water flow.

[0027] The sealing plate 7 is located directly above the water inlet 6, and the sealing plate 7 is made of rubber. By setting the sealing plate 7, when water flow sampling is carried out, the water flow outside the sampling bucket 1 can impact the sealing plate 7, causing the sealing plate 7 to bend upward, thereby opening the water inlet 6. When the water flow sampling ends, the water flow inside the sampling bucket 1 can squeeze the sealing plate 7 in the opposite direction, thereby closing the water inlet 6, thus achieving the one-way flow effect of the water flow inside the sampling bucket 1, thereby bringing convenience to water flow sampling.

[0028] The counterweight 8 is made of stainless steel and is parallel to the closed plate 7. By setting the counterweight 8, when water flow sampling is carried out, the counterweight 8 greatly increases the weight of the sampling bucket 1, thereby increasing the sinking speed of the sampling bucket 1, that is, increasing the water inflow speed inside the sampling bucket 1, and thus improving the water flow sampling efficiency.

[0029] The auxiliary mechanism 9 includes a fixing frame 91, which is fixedly connected to the side of the inner wall of the collection bucket 1. A thermometer 92 is fixedly sleeved inside the fixing frame 91. By setting up the auxiliary mechanism 9, the thermometer 92 can detect the temperature of the collected sample when groundwater sampling is carried out, so that the staff can observe the groundwater temperature at the first time, thereby improving the convenience of water flow sampling.

[0030] The discharge mechanism 10 includes a drain pipe 101, which is fixedly sleeved on the side of the collection bucket 1. A flexible tube 102 is fixedly sleeved at one end of the drain pipe 101, and a spring clip 103 is fixedly sleeved at the other end of the drain pipe 101. By setting up the discharge mechanism 10, when water flow sample extraction is required, the spring clip 103 is removed and one end of the flexible tube 102 is sleeved inside the test tube, so that the water flow inside the collection bucket 1 can slowly flow into the test tube through the flexible tube 102, thereby facilitating the collection of water flow samples.

[0031] The sealing mechanism 11 includes a top cover 111, which is threaded onto the top of the collection bucket 1. The top of the top cover 111 has an exhaust hole 112. By setting the sealing mechanism 11, when water flow sampling is performed, the top cover 111 is fitted onto the top of the collection bucket 1, and the top cover 111 can seal the collection bucket 1, thereby preventing the mud and sand from the inner wall of the deep well from entering the collection bucket 1 when it is extracted, thus achieving the protection effect of the water flow sample.

[0032] The working principle of the hydrogeological groundwater and surface water fixed-depth and quantitative sampler provided by this utility model is as follows:

[0033] Step 1: First, when deep well water sampling is required, fix one end of the pull rope 4 inside the positioning ring 3. Then, lower the collection bucket 1 into the deep well, allowing water to enter through the inlet 6. When the water sampling is complete, raise the pull rope 4, causing the collection bucket 1 to rise. This closes the inlet 6 with the sealing plate 7, allowing the water to be extracted from the deep well. This avoids the inconvenience of water transport via pipelines, thus facilitating groundwater sampling. During water flow sampling, staff can directly observe the water flow inside the sampling bucket 1, facilitating water flow observation. When sampling occurs, the water flow outside the sampling bucket 1 impacts the sealing plate 7, causing it to bend upwards and opening the inlet 6. At the end of sampling, the water flow inside the sampling bucket 1 forces the sealing plate 7 in the opposite direction, closing the inlet 6. This achieves a unidirectional flow effect within the sampling bucket 1, thus facilitating water flow sampling.

[0034] Step 2: When water flow sampling is performed, the counterweight 8 greatly increases the weight of the collection bucket 1, thereby increasing the sinking speed of the collection bucket 1, which in turn increases the water inflow speed inside the collection bucket 1, thus improving the water flow sampling efficiency. When groundwater sampling is performed, the thermometer 92 can detect the temperature of the collected sample, allowing staff to observe the groundwater temperature immediately, thereby improving the convenience of water flow sampling. When water flow sample extraction is required, the spring clip 103 is removed and one end of the flexible tube 102 is connected to the inside of the test tube, allowing the water flow inside the collection bucket 1 to slowly flow into the test tube through the flexible tube 102, thus facilitating the collection of water flow samples. When water flow sampling is performed, the top cover 111 is connected to the top of the collection bucket 1. At this time, the top cover 111 can seal the collection bucket 1, thereby preventing the sediment from the inner wall of the deep well from entering the collection bucket 1 during extraction, thus achieving the protection effect of the water flow sample.

[0035] Compared with related technologies, the hydrogeological groundwater and surface water fixed-depth and quantitative sampler provided by this utility model has the following beneficial effects:

[0036] By setting up the positioning frame 2, when deep well water sampling is required, one end of the pull rope 4 is fixed inside the positioning ring 3. At this time, the sampling bucket 1 is dropped into the deep well, allowing water to enter the sampling bucket 1 through the inlet 6. When the water sampling is finished, the pull rope 4 is lifted, causing the sampling bucket 1 to be lifted. The sealing plate 7 then seals the inlet 6, allowing the water to be extracted from the deep well. This avoids the inconvenience of water transportation through pipelines and brings convenience to groundwater sampling.

Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
