Description

Technical Field

[0001] The present invention belongs to the technical field of sampling devices, and more specifically, relates to a geological survey sampling device with a water sampling function. Background Art

[0002] In geological surveys, understanding underground geological structures and water resource conditions often requires the use of specialized sampling equipment to collect underground and water samples in stages. For example, when studying areas with multi-layered geological structures, each potentially containing water resources with different characteristics, sampling and analysis at different strata depths is necessary to assess the impact of geological structures on groundwater, analyze vertical variations in groundwater composition, and study the relationship between geological changes and hydrological variations.

[0003] However, during the actual geological survey sampling process, traditional geological survey sampling devices are subject to varying degrees of interference in the water channel during the first sampling due to factors such as frictional heat generated by the drill bit, soil and rock, and changes in formation pressure. Debris generated by this friction easily mixes into the water sample, causing contamination. This not only affects subsequent analysis of the sample's composition and leads to deviations in the first sampling results, but also can cause excessive impurities to clog the internal channels of the water sampling device, increasing the risk of equipment failure before the second sampling, thereby reducing the efficiency of the entire sampling process.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The present invention provides a water seepage ring on the outer cylinder, so that the device can preliminarily filter the incoming water during the sampling process, thereby improving the purity of the water sample obtained by the device. The water seepage ring is composed of a metal filter ring and a ceramic filter ring. The arc-shaped partition in the middle cavity divides it into multiple groups of water seepage chambers. The compression spring and pressure plate structure in the water seepage chamber can be sealed by utilizing the centrifugal force when the outer cylinder rotates downward. The pressure plate is caused to slide on the slide rail structure by centrifugal force and moves along the direction of the compression spring to ensure the tightness of the seal between the metal filter ring and the pressure plate, so that the device can prevent impurities from entering when the outer cylinder is rotating, thereby improving the dustproof ability of the device to cope with complex geological environments.

[0018] 2. When using the device, the filter bucket, impeller, and scraper on the filter cartridge can be coordinated to clean impurities in the water, making the device less likely to clog during the water intake process and improving the smoothness of the water intake of the device. The filter bucket cooperates with the end cover of the spirally distributed water inlet to guide the water flow in. The impeller rotates under the drive motor, driving the scraper to clean the impurities on the filter bucket and discharge them through the slag discharge port. Then, through the filter plate and the water outlet at the bottom of the filter cartridge, the device can further purify the water sample and smoothly introduce it into the water intake chamber, ensuring that the obtained water sample meets the requirements of subsequent analysis, thereby improving the quality and reliability of the water intake of the device.

[0019] 3. By incorporating a magnetic float and a control module within the holding tube, the present invention enables the device to monitor the water level within the holding tube, enhancing its ability to monitor water intake status. The magnetic float rises and falls with the water level, moving closer to or further away from the reed switch, triggering a signal transmitted to the control module. This water-level sensing mechanism provides timely feedback on water intake progress, enabling operators to monitor intake status and adjust operations accordingly, improving the device's controllability and adaptability during the water intake process.

[0020] 4. The placement table in the collection assembly is connected to the base via support columns and buffer columns, absorbing vibrations generated by the device's operation and preventing them from affecting other components and samples. The control module adjusts the position of the electric push rod and clamp ring on the placement table to secure the sampling tube. An oscillating motor at the bottom of the placement table, controlled by the control module, oscillates the sample on the placement table, promoting separation of the sample from the sampling tube, improving the device's sample handling capacity, and facilitating subsequent sample analysis.

[0039] like Figure 3As shown, a sampling cylinder 203 is housed within an outer cylinder 201. A partition 204 is installed within this cylinder, dividing the inner cavity of the sampling cylinder 203 into a core sampling chamber and a water sampling chamber. This arrangement allows for simultaneous core sampling and water sampling during the same drilling process, enabling the device to acquire a variety of geological samples and enhancing its sampling versatility. A holding cylinder 205 is placed within the water sampling chamber to store collected water samples. A filter cartridge 206 is installed near one end of the sampling cylinder 203, near the water sampling chamber, to perform preliminary filtration on the water sample entering the chamber.

[0040] like Figure 1 、 14 As shown, a control module 301 is provided on the base 101. The control module 301 is electrically connected to the elevator 102 and the driver 104. The control module 301 sends control signals to the elevator 102 and the driver 104 to control the elevator 102's elevation and the driver 104's start and stop. The control module 301 can be an ARK-3500 industrial computer. The elevator 102 can be a screw elevator, and the driver 104 can be a hydraulic motor. The base 101 is provided with a collection assembly for collecting samples. The cooperation of the salvage device 509 and the winch 511 in the collection assembly can lift the sampling tube 203 from underground to the surface, allowing the user to obtain the collected sample.

A cavity is formed between the metal filter ring 207 and the ceramic filter ring 208, and a plurality of groups of arc-shaped partitions 209 are provided in the cavity, and the plurality of groups of arc-shaped partitions 209 divide the cavity into a plurality of groups of water seepage chambers; a compression spring 211 and a pressure plate 212 are provided in the plurality of groups of water seepage chambers, and the pressure plate 212 is connected to the metal filter ring 207 through the compression spring 211, and the pressure plate 212 is slidably connected to the water seepage ring through a slide rail structure; through the arrangement of the compression spring 211 and the pressure plate 212, the centrifugal force generated by the rotation of the outer cylinder 201 can be utilized during the drilling process of the device to form a sealing structure between the pressure plate 212 and the metal filter ring 207, so that the user can ensure the sealing performance of the water seepage ring without intervention, thereby improving the sealing and reliability of the device under different drilling conditions. A sealing groove is provided on the inner wall of the metal filter ring 207 , a sealing protrusion 214 is provided on one side of the pressure plate 212 , a sealing ring 215 is sleeved on the sealing protrusion 214 , and the sealing protrusion 214 is clamped in the sealing groove, further enhancing the sealing effect.

[0042] like Figure 6 、 7As shown, a filter hopper 216 and an end cover 217 are provided at one end of the filter cartridge 206 away from the sampling cartridge 203. Multiple water inlet channels are provided in the end cover 217, and the multiple water inlet channels are spirally distributed on the end cover 217.

The drive motor 219 can be a Maxon EC 4pole The 30-model DC brushless motor, the drive motor 219 can detect the rotation speed of the shaft end through self-feedback. When the water pressure is normal, the spiral water inlet can provide an initial rotational force for the incoming water to drive the impeller 218 to rotate. When the water pressure is abnormal, the rotation speed is too low. The user can start the drive motor 219 through the control module 301 to drive the impeller 218 to rotate, so that the device can stir and guide the water flow, thereby improving the filtration efficiency of the device for water samples and enhancing the user's ability to control the water flow filtration process.

[0043] The filter cartridge 206 is provided with a slag discharge port, and multiple groups of slag discharge ports are rotatably provided with a gate 222; the impeller 218 is connected to the scraper 221 above the filter bucket 216. When the impeller 218 rotates, the scraper 221 synchronously cleans the impurities on the filter bucket 216. The filter bucket 216 is provided with a convex edge for temporarily storing impurities. When there are too many impurities, the gate 222 can be squeezed to open it and discharge the impurities. A filter plate 223 is provided at the bottom of the filter cartridge 206, and a water outlet is provided at the bottom of the filter cartridge 206.

The control module 301 receives the speed signal sent back by the drive motor 219, thereby controlling the start and stop of the drive motor 219. The drive motor 219 can be powered by its own lithium battery.

[0044] like Figure 3 、 8As shown in Figures 9 and 9, the water intake chamber is equipped with a baffle 224 with a water inlet. A removable water inlet cap 213 is installed at one end of the receiving tube 205, which houses a waterproof chamber. The waterproof chamber houses a transmitter module 401, a reed switch 402, and a power supply 403. The transmitter module 401 is electrically connected to the reed switch 402 and the power supply 403, respectively. A guide tube 404 is installed within the receiving tube 205, which houses a magnetic float 405. When the water level reaches a set height, the float triggers the reed switch, completing the circuit, and the transmitter module 401 sends a signal to the ground controller. Energizing the electromagnetic ring 408 generates a magnetic field, which repels the sealing ring 409 and compresses the return spring 411, opening the water intake chamber. The corrugated protective cover 412 is made of fluororubber to prevent spring corrosion. Thereby, the automatic closing of the accommodating tube 205 can be achieved.

The electromagnetic ring 408 is magnetically connected to the sealing ring 409, and one end of the multiple groups of return springs 411 is connected to the sealing ring 409, and the other end is connected to the water guide sleeve 407. The multiple groups of return springs 411 are all provided with a corrugated protective cover 412, and the transmitting module 401 is electrically connected to the electromagnetic ring 408 and the control module 301 respectively.

[0046] An adjustment tube 501 is inserted into the sampling tube 203. The sampling tube 203 is provided with a spiral groove, and a protrusion 502 is provided on the adjustment tube 501. The protrusion 502 is slidably connected to the spiral groove. This arrangement can guide the rotation direction of the adjustment tube 501, allowing the adjustment tube 501 to rotate in a certain direction.

The gripping ring 503 has multiple sets of guide grooves, and multiple sets of clamping blocks 504 are installed in the guide grooves. A pressure ring 505 is installed inside the gripping ring 503. The pressure ring 505 has a first guide surface 506, and the clamping blocks 504 have a second guide surface 507. The first guide surface 506 contacts the second guide surface 507. The pressure ring 505 is connected to the adjustment tube 501 via a bellows coupling 508. When the user operates the adjusting cylinder 501, the bellows coupling 508 transmits the rotational force of the adjusting cylinder 501, and the pressure ring 505 pushes the clamping block 504 through the guide surface to achieve the gripping or loosening of the sampling object, so that the device can better adapt to the collection of samples of different shapes and textures, improve the device's ability to fix and collect samples during sampling, and enhance the user's ability to cope with the collection of various samples.

[0047] like Figures 11 to 14 As shown, the collection assembly includes a salvage device 509 and a winch 511. The salvage device 509 is located above the sampling tube 203. The winch 511 is rotatably connected to the base 101 via a bearing. A connecting tube 512 is provided between the salvage device 509 and the sampling tube 203.

[0048] The adjustment tube 501 is provided with multiple sets of stoppers 513 at one end, each of which is detachably provided with a snap ring 514. The stoppers 513 and snap ring 514 define the connection position and range of motion of the adjustment tube 501 with other components, allowing the user to control the state of the adjustment tube 501 during operation, thereby improving the accuracy of the device's structural connection and adjustment. The sampling tube 203 is provided with a stopper groove, and the bottom of the connecting tube 512 is provided with two sets of snap rings. The stoppers 513 pass through the stopper grooves and are secured to one of the snap rings via a snap ring 514. The sampling tube 203, near the connecting tube 512, is detachably provided with a fixing ring 523, which is located in the other set of snap rings. The user can secure the connection between the sampling tube 203 and the connecting tube 512 by inserting the fixing ring 523 into the corresponding snap ring.

A connecting post 516 is provided at one end of the connecting tube 512, distal from the sampling tube 203. This connects the connecting tube 512 to the overshot 509. The provision of the connecting post 516 facilitates the connection between the connecting tube 512 and the overshot 509, allowing the user to conveniently raise and lower the sampling tube 203 with the aid of the overshot 509, thereby enhancing the operability of the device during sample recovery. In actual use, the user can retrieve the sampling tube 203 by controlling the overshot 509, enabling the device to better meet the practical needs of geological survey sampling, improving its practicality throughout the sampling process, and increasing the user's efficiency in sample acquisition.

[0049] The collection assembly also includes a placement table 517. Two sets of support columns 518 are provided on the base 101. These two sets of support columns 518 are connected to the placement table 517 via multiple sets of buffer columns 519. The buffer columns 519 absorb vibrations generated during operation, preventing them from being transmitted to other components on the base 101. The placement table 517 is equipped with two sets of electric push rods 521, each with a clamping ring 522 attached to its movable rod. The user can operate the push rods 521 through the control module 301 to adjust the position of the clamping ring 522, allowing the device to position the sampling tube 203. An oscillation motor 515 is provided at the bottom of the placement table 517. The control module 301 is electrically connected to the push rods 521 and the oscillation motor 515, respectively. The oscillation motor 515 allows the sample on the placement table 517 to be vibrated, allowing the user to facilitate separation of the sample from the sampling tube 203, thereby improving the device's sample processing capabilities.

[0050] Example 2: Based on the geological survey and sampling device with a water extraction function provided in Example 1 of this application, Example 2 of this application provides a geological survey and sampling device with a water extraction function. This Example 2 is merely a preferred embodiment of Example 1, and its implementation will not affect the independent implementation of Example 1. Example 2 of the present invention will be further described below.

A water inlet end cap 213 is detachably provided at one end of the receiving tube 205, and a waterproof chamber is provided in the water inlet end cap 213. In the water intake chamber, the water baffle 224 serves as a guide. Through the water inlet provided on the water baffle 224, the water sample can be guided to flow into the receiving tube 205, so that the user can ensure that the water sample enters the storage area according to the predetermined path, while preventing the water hammer effect. A transmitting module 401, a reed switch 402, and a power supply 403 are provided in the waterproof chamber. The transmitting module 401 is electrically connected to the reed switch 402 and the power supply 403, respectively, to form a collaborative water level monitoring and control unit. Through this setting, the water level changes in the receiving tube 205 can be sensed and corresponding controls can be made, so that the user can understand the water intake status. A guide tube 404 is provided in the accommodating cylinder 205, and a magnetic float 405 is provided in the guide tube 404. The magnetic float 405 rises and falls with the water level, approaches or moves away from the reed switch 402, and the trigger signal is transmitted to the emission control module 301. The device uses this water level sensing mechanism to provide timely feedback on the water extraction progress.

[0052] In the first embodiment, the magnetic float 405 alone triggers the reed switch 402 to control the operation of related components. In the second embodiment, a damping ring 406 is added to the magnetic float 405. When the water level in the water intake chamber changes, the magnetic float 405 moves within the guide tube 404. The damping ring 406, slidably connected to the guide tube 404, slows the movement of the magnetic float 405. This prevents frequent false triggering of the reed switch 402 due to rapid water level fluctuations, making the signal received by the transmitting module 401 more stable and accurate. For example, during surveying and sampling in areas with complex geological structures and unstable groundwater flow rates, water level fluctuations are relatively severe. The device in the first embodiment may cause the reed switch 402 to open and close frequently due to the rapid movement of the magnetic float 405, resulting in signal distortion. The second embodiment, through the provision of the damping ring 406, overcomes this problem, ensuring more reliable water inflow control in the holding tube 205 and improving the device's adaptability and stability in complex hydrogeological conditions. The remaining conditions are the same as those in Example 1, so they will not be described in detail in this example.

[0053] The basic principles, main features and advantages of the present invention are shown and described above. It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments.
