Description

Technical Field

[0001] This utility model relates to the field of water sampling technology, specifically a probe for water sampling in hydrogeology and environmental geology. Background Technology

[0002] Hydrogeology and environmental geology is a general term encompassing hydrogeology, engineering geology, and environmental geology. When conducting hydrogeological and environmental geological surveys, it is necessary to take geological water samples, which requires the use of sampling probes.

[0003] For example, a Chinese patent (publication number: CN221326030U) discloses a water sampling probe for hydrogeological and environmental geological conditions. It includes a soil-shoveling probe, a detachable threaded water-collecting rod attached to the upper end of the soil-shoveling head, and a positioning frame. The lower end of the probe tube of the water-collecting rod is detachably threaded onto the upper end of the soil-shoveling probe. During sampling, soil is first removed through the soil-shoveling probe to form a sampling pit. After water seeps into the sampling pit, a water pump attached to the upper end of the probe tube extracts the water from the pit. This allows the hydrogeological and environmental geological water sampling probe to both sample soil and extract water from the sampling pit via the water-collecting rod. Simultaneously, the probe tube is movably inserted into the upper end of the positioning frame, which positions the water-collecting rod in the soil. The positioned water-collecting rod is then easier to move up and down.

[0004] This patent achieves the function of water sampling by extracting water from the sampling pit through a water pump installed at the upper end of the probe. However, the sampling probe requires the soil to be dug out through the soil shovel probe to take a sample, which is inconvenient to use. Therefore, a probe for water sampling in hydrogeology and environmental geology is proposed to solve the above-mentioned problems. Utility Model Content

[0022] 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.

[0023] Please see Figures 1 to 3 The probe for sampling water in hydrogeological environment in this embodiment includes a handle 1, a connecting plate 2 fixed to the bottom of the handle 1, two connecting frames 3 fixed to the bottom of the connecting plate 2, a fixing cylinder 4 fixed between the two connecting frames 3, a fixing block 5 fixed to the top of the fixing cylinder 4, and an extension component provided on the inner side of the fixing block 5.

[0024] Understandably, the handle 1 facilitates the movement of the entire probe, thereby improving the overall ease of use. The extension component facilitates the displacement of the lifting cylinder 12, thereby facilitating rapid water sampling and further enhancing the overall ease of use.

[0025] It is also understandable that a sleeve 7 is fixed on the extension component, a water pump 8 is fixed inside the sleeve 7, an extraction pipe 9 is fixed at the bottom of the water pump 8, a drill bit 13 is fixed at the bottom of the fixed cylinder 4, and a limiting component 14 is provided on the drill bit 13.

[0026] It should be noted that the installation of water pump 8 and extraction pipe 9 facilitates the extraction of water samples from the lifting cylinder 12, thereby enabling the probe to perform water sampling and improving overall ease of use.

[0027] The extension assembly includes a rotating column 6 rotatably connected to the fixed block 5. A rotating cylinder 11 is fixed at the bottom of the rotating column 6. A limiting cylinder 10 extending into the inner cavity is fixed at the top of the fixed cylinder 4. A spiral opening penetrating into the inner cavity is provided on the outer side of the limiting cylinder 10. A limiting opening penetrating into the inner cavity is provided on the outer side of the rotating cylinder 11.

[0028] The spiral port and the limiting port are designed to limit the movement of the lifting cylinder 12, thereby ensuring the stable lifting and lowering of the lifting cylinder 12, improving the overall stability of the probe, and ensuring stable overall use.

[0029] It should also be noted that a displacement column head is fixed on the outside of the lifting cylinder 12. The displacement column head is slidably connected to the limiting cylinder 10 and the rotating cylinder 11 through a spiral port and a limiting port, respectively. An installation port is opened on the top of the fixed cylinder 4, and the top of the limiting cylinder 10 is located inside the installation port.

[0030] The setting of the displacement column head facilitates the coordination between the limiting cylinder 10 and the rotating cylinder 11, thereby enabling the lifting function of the lifting cylinder 12, which in turn facilitates water sampling after the bottom is inserted into the ground, and improves the ease of use of the probe.

[0031] It can be observed that the inner side of the rotating cylinder 11 is rotatably connected to the inner side of the limiting cylinder 10, and the inner side of the rotating cylinder 11 is movably connected to the lifting cylinder 12. The extraction tube 9 passes through the rotating column 6 and extends into the inner cavity of the lifting cylinder 12.

[0032] The rotating connection facilitates the stable rotation of the lifting cylinder 12, which in turn facilitates its lifting and lowering, thus contributing to the stable use of the entire probe and improving its overall stability.

[0033] The lifting cylinder 12 is rotatably connected to the inner side of the rotating cylinder 11. The bottom of the fixed cylinder 4 is provided with a through-hole, which is adapted to the size of the lifting cylinder 12. The extraction tube 9 is a flexible tube that passes through the rotating column 6 and extends to the bottom of the inner cavity of the lifting cylinder 12.

[0034] In this embodiment, the through-hole design facilitates the stable displacement of the lifting cylinder 12, and the flexible hose design ensures stable water sampling during the lifting and lowering of the lifting cylinder 12, thereby improving the overall stability of use.

[0035] Please see Figure 4 In order to ensure the stable use of the probe, the limiting component 14 in this embodiment includes two left and right rotating shafts 1401 that are rotatably connected to the bottom of the drill bit 13. A sealing plate 1402 is fixed on the outside of the rotating shaft 1401, and a resistance reducing plate 1403 is fixed on the bottom of each of the two sealing plates 1402.

[0036] It can also be seen that the setting of the sealing plate 1402 is conducive to sealing the inner cavity of the drill bit 13, thereby preventing soil from entering and facilitating the stable use of the probe. The setting of the resistance reducing plate 1403 is conducive to reducing the pressure of insertion into the ground by tilting, thereby facilitating the insertion and sinking of the probe rod and improving the use effect of the probe rod.

[0037] A slot is provided on the right side of the left-side drag-reducing plate 1403, and a protrusion is fixed on the left side of the right-side drag-reducing plate 1403. The protrusion engages with the slot. A hook plate 1404 is fixed on the top of the rotating shaft 1401. A connecting plate 1405 is fixed on the inner wall of the drill bit 13 on both sides. The hook plate 1404 engages with the connecting plate 1405.

[0038] In this embodiment, the protrusions and latches help to further lock the sealing plate 1402, thereby improving the overall stability of use. The hook plate 1404 and the connecting plate 1405 are engaged to prevent soil from pushing against the sealing plate 1402, thus preventing soil from entering and improving the stability of the probe.

[0039] All electrical components mentioned in this article are electrically connected to the controller and power supply. The control method of this utility model is controlled by the controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the art. Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail.

[0040] The working principle of the above embodiments is as follows:

[0041] Using handle 1, lift the entire device and move it to the location where water sampling is required. Through the conical structure of the resistance-reducing plate 1403 and drill bit 13, the entire probe is drilled downwards to the desired depth. Then, rotate the sleeve 7, which, through its fixing action, drives the rotating cylinder 11 to rotate. The displacement column and the spiral port allow for rotational displacement of the displacement column and the lifting cylinder 12. The limiting port of the limiting cylinder 10 limits the left and right displacement of the lifting cylinder 12, thus achieving the lifting and lowering of the lifting cylinder 12. The lifting cylinder 12 is lowered out of the fixed cylinder 4 by impacting the sealing plate 1402 at the bottom of the lifting cylinder 12, unlocking the protrusion and the locking mechanism, and simultaneously locking the hook plate 1404 and the connecting plate 1405. Through the rotation of the rotating shaft 1401, the sealing plate 1402 and the resistance reducing plate 1403 are opened to both sides, thereby enabling the bottom of the lifting cylinder 12 to contact the water source. Then, the water pump 8 is started, and the water sample is extracted through the extraction pipe 9 to achieve sampling by the probe. The overall structure is simple, convenient to use, effective, and easy to sample.
