[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] In practical implementation: such as Figures 1-4 As shown, a groundwater sampler for environmental geological engineering includes: a base 1, a support assembly 6, a guide ring 7, and a reinforcing assembly 8. Two limiting frames 2 are fixedly connected to the top of the base 1. A turntable 4 is movably inserted at the axis of the two limiting frames 2. A flexible hose 5 is wound around the surface of the turntable 4. The support assembly 6 is fixedly mounted on the limiting frames 2 and located on one side of the turntable 4. The guide ring 7 is fixedly mounted on the support assembly 6. A guide roller 71 is movably inserted inside the guide ring 7. A pressure plate 72 is movably mounted on one side of the guide roller 71 and slides inside the guide ring 7. One end of the flexible hose 5 extends outward and passes between the guide roller 71 and the pressure plate 72. One end of the flexible hose 5 is fixedly connected to the water collection box of the underwater sampler. Two sets of reinforcing assemblies 8 are provided, and both sets of reinforcing assemblies 8 are located on the support assembly 6.
[0027] In this way, when it is necessary to collect groundwater, the base 1 is first placed next to the wellhead of the deep well. The base 1 supports the two limit frames 2 above. The turntable 4 is connected to the two limit frames 2 with bearings to reduce friction. The turntable 4 will rotate inside the two limit frames 2 to retract and extend the hose 5, increasing the safety of the hose 5 in use.
[0028] The support assembly 6 mainly supports and extends the guide ring 7. The guide ring 7 is supported above the wellhead by the support assembly 6. One end of the hose 5 is inserted into the guide ring 7 and fixed to the water sampler. The water sampler slides down into the well. During the descent of the water sampler, the hose 5 slides on the surface of the guide roller 71. The guide roller 71 rolls inside the guide ring 7, reducing the friction with the guide ring 7. When the water sampler reaches the expected height, the pressure plate 72 can squeeze the hose 5. The two sides of the hose 5 stop conveying due to the squeezing of the guide roller 71 and the pressure plate 72, which can easily fix the position and height of the water sampler. The surface of the hose 5 is engraved with a scale, which can easily observe the extension length of the hose 5. The extension and guidance of the hose 5 by the guide ring 7 greatly reduces the friction between the hose 5 and the inner wall of the wellhead, and greatly increases the service life of the hose 5.
[0029] like Figure 1 , Figure 2 and Figure 3As shown, a handle 3 is fixedly connected to one side of the outer wall of the limiting frame 2. One side of the handle 3 extends towards the other limiting frame 2. The upper surface of the handle 3 is provided with anti-slip texture 31. The handle 3 is fixed to the outer wall of the limiting frame 2. The handle 3 is located below the two limiting frames 2, which makes it convenient for workers to lift. The handle 3 is semi-enclosed. The gap between the handle 3 and the limiting frame 2 makes it convenient to wind the hose 5.
[0030] Preferably, the support assembly 6 includes a slide rail 61 fixedly inserted into the two limiting frames 2. A slider 62 is slidably sleeved on the surface of the slide rail 61. An extension rod 63 is movably connected to the upper surface of the slider 62. The extension rod 63 extends away from the turntable 4 and is fixedly connected to the outer wall of the guide ring 7. The slide rail 61 can limit the slider 62 while increasing the stability between the two limiting frames 2, supporting the two limiting frames 2 and increasing the structural strength. The slider 62 can slide on the surface of the slide rail 61 during installation, making it convenient to adjust the position of the slider 62. After installation, a bolt is inserted through the bottom of the slider 62, and the end face of the bolt contacts the slide rail 61, fixing the slider 62 above the slide rail 61. The extension rod 63 is movably connected to the top of the slider 62 through a column. The position of the guide ring 7 can be easily adjusted by swinging the extension rod 63, making it convenient to use.
[0031] like Figure 2 , Figure 3 and Figure 4 As shown, a threaded rod 73 is threaded into the inside of the guide ring 7. One end of the threaded rod 73 is movably inserted into the outer wall of the pressure plate 72. Limiting grooves 76 are symmetrically opened on both sides of the guide ring 7. Limiting rods 77 are fixedly inserted into both sides of the pressure plate 72. One end of each limiting rod 77 is inserted into the two limiting grooves 76 and slides.
[0032] The threaded rod 73 supports the pressure plate 72. A bearing ring is installed at the connection between the pressure plate 72 and the threaded rod 73. When the threaded rod 73 rotates, the pressure plate 72 will slide inside the guide ring 7. When the pressure plate 72 slides, the limiting rods 77 inserted on both sides will slide along the limiting groove 76 against the inner wall of the guide ring 7, increasing the stability of the pressure plate 72 during the sliding process. The sliding of the pressure plate 72 can reduce the gap between the pressure plate 72 and the guide roller 71, making it easier to fix the hose 5.
[0033] The other end of the threaded rod 73 is fixedly connected to a knob 74. The knob 74 is located outside the guide ring 7 and rotates. The diameter of the knob 74 is larger than that of the threaded rod 73. The surface of the knob 74 is wrapped with protrusions in an annular shape, which can increase the friction of the surface of the knob 74 and make it easier to rotate the knob 74.
[0034] like Figure 2 , Figure 3 and Figure 4As shown, the guide roller 71 is symmetrically fitted with limiting rings 75. The diameter of the two limiting rings 75 is larger than the diameter of the guide roller 71. The two limiting rings 75 are located on both sides of the hose 5 and rotate. When the guide roller 71 guides the hose 5, the two sides of the hose 5 will contact the limiting rings 75. The limiting rings 75 are mainly used to limit the hose 5, reduce the left and right sliding of the hose 5 above the guide roller 71 when sliding, and increase stability and safety.
[0035] like Figure 2 , Figure 3 and Figure 4 As shown, the reinforcing component 8 includes a connecting block 82 fixedly connected to the upper surface of the slide rail 61, a limiting post 81 fixedly connected to the middle surface of the extension rod 63, a support rod 83 movably connected between the limiting post 81 and the connecting block 82, and a sliding rod 84 movably connected to the middle of the support rod 83. When the extension rod 63 supports the guide ring 7, the connecting block 82 installed on the extension rod 63 will be movably connected to the limiting post 81 through the rotating support rod 83, so that the support rod 83 can swing along with the extension rod 63. When swinging, the sliding rod 84 inserted inside the support rod 83 will slide to reduce and increase the length of the support rod 83, thereby increasing the swing amplitude of the support rod 83 and improving the stability and structural strength of the extension rod 63 during use.
[0036] Explain the basic components of the equipment, how to use them, and then explain the beneficial effects of improved components on the equipment.
[0037] When using this invention to collect groundwater, the base 1 is first placed next to the wellhead of the deep well. The base 1 supports two limiting frames 2 above it. Bearings are installed at the connection between the turntable 4 and the two limiting frames 2 to reduce friction. The turntable 4 rotates inside the two limiting frames 2 to control the extension and retraction of the hose 5, increasing the safety of the hose 5 during use. The support assembly 6 mainly supports and extends the guide ring 7. The guide ring 7 is supported above the wellhead by the support assembly 6. One end of the hose 5 is inserted into the guide ring 7 and fixed to the water sample collector. The water sample collector slides down into the well. During the descent of the water sampler, the hose 5 slides on the surface of the guide roller 71. The guide roller 71 rolls inside the guide ring 7, reducing friction with the guide ring 7. When the water sampler reaches the expected height, the pressure plate 72 can squeeze the hose 5. The hose 5 stops conveying on both sides due to the squeezing of the guide roller 71 and the pressure plate 72, which can easily fix the position and height of the water sampler. The surface of the hose 5 is engraved with a scale, which can easily observe the extension length of the hose 5. The extension and guidance of the hose 5 by the guide ring 7 greatly reduces the friction between the hose 5 and the inner wall of the wellhead, greatly increasing the service life of the hose 5.
[0038] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
