Description

Technical Field

[0001] This invention relates to the field of geological exploration technology, specifically to a sample collection device for geological exploration engineering. Background Technology

[0002] There are various types of sample collection devices for geological exploration engineering, and water sample collection is one of them. When collecting samples from deep water sources, either a water pump is used to collect the water source samples, or a water sample collection device is placed at the water source to collect the water samples.

[0003] A search revealed a hydrogeological exploration sampling device (publication number CN114646496B), comprising a descent component, a soil sampling component, a water sampling component, and a signal component. The soil and water sampling components automatically control the soil and water sampling process. This device collects water samples by placing it at a water source. A coal mine hydrogeological exploration pumping test device (publication number CN216695727U) includes a pumping pipe, a pump, a sampling unit, two electro-hydraulic push rods, a sampling plate, a control unit, and a sampling cylinder. This device solves the problem of low sampling efficiency in coal mines due to the complex process of water sampling during pumping tests. This device collects water samples by pumping water from the source.

[0004] In existing technologies, when a water sampling device is placed at a water source, it needs to be moved out of the water source after each water sampling, and the collected water sample needs to be taken out and then put back into the water for sampling. This makes it impossible to conduct continuous sampling, reduces sampling efficiency, and the water pump can cause the water flow rate to be too fast, which can cause the water source to be disturbed, resulting in changes in the physical properties of the water, disruption of chemical balance, and interference with biological activity, thus distorting the representativeness of the sample. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a sample collection device for geological exploration engineering, which solves the problem that existing water sample collection devices require moving the device out of the water source after collecting the water sample, then removing it and putting it back into the water source, resulting in the inability to continuously sample and reduced sampling efficiency.

[0006] To achieve the above objectives, this invention provides a sample collection device for geological exploration engineering, comprising a splicing mechanism, a rotation and transformation mechanism, and a mounting frame arranged sequentially from top to bottom. Force transmission mechanisms are provided on both sides of the splicing mechanism, and the rotation and transformation mechanism cooperates with the force transmission mechanisms to replace the sampling container. A sampling mechanism is provided on one side of the bottom of the rotation and transformation mechanism for controlling the sampling container to collect water samples. A disassembly and assembly mechanism is rotatably connected to the middle of the mounting frame for installing the sampling mechanism.

[0007] Furthermore, the rotation conversion mechanism is fixedly connected to the top of the mounting frame via a mounting plate. The mounting plate has a quadrilateral rotation groove with all four sides recessed towards the center. A mounting column is rotatably connected to the top of the mounting plate, and a connecting plate is fixedly connected to one side of the mounting column. The connecting plate has a mounting groove and a tension spring disposed within the mounting groove. A limiting slide groove communicating with the mounting groove is formed inside the connecting plate. A limiting slide post is slidably connected inside the limiting slide groove, and the bottom of the limiting slide post is disposed inside the rotation groove.

[0008] Furthermore, a fixing plate is fixedly connected to the outside of the mounting column, and a receiving groove is formed inside the fixing plate. A sliding groove adjacent to the receiving groove is also formed inside the fixing plate. The sampling mechanism includes multiple sampling bottles disposed inside the mounting frame. An inner tube is fixedly connected to the middle of each sampling bottle, and multiple water inlet holes are formed at the bottom of the inner tube. A sliding stopper is slidably connected inside the inner tube, and a pull rope is fixedly connected to the top of the sliding stopper. A push spring is installed inside the inner tube, and a vertical rod is fixedly connected to the top of the pull rope. An anti-detachment plate is fixedly connected to the top of the vertical rod.

[0009] Furthermore, one end of the push spring is fixedly connected to the inner top of the inner tube, and the other end of the push spring is fixedly connected to the top of the slide plug. A push-back spring is provided inside the loading groove, and a connecting block is slidably connected inside the loading groove. A slide rod that slides inside the sliding groove is fixedly connected to the outside of the connecting block, and a limiting circular plate is fixedly connected to both the upper and lower ends of the slide rod; wherein, a bent rod is fixedly connected to the bottom of the lower limiting circular plate, and a semi-circular sleeve is fixedly connected to the bottom of the bent rod.

[0010] Furthermore, one end of the push-back spring is fixedly connected to the inside of the mounting groove, and the other end of the push-back spring is fixedly connected to one end of the connecting block. A blocking plate is fixedly connected to the top and middle of the limiting slide post, and the two blocking plates are respectively disposed on the upper and lower sides of the connecting plate. One end of the tension spring is fixedly connected to the inside of the mounting groove, and the other end of the tension spring is fixedly connected to the side of the limiting slide post near the mounting post.

[0011] The geological exploration engineering sample collection device provided by this invention has the following beneficial effects:

[0012] 1. By coordinating the rotation and transformation mechanism, the force transmission mechanism, and the sampling mechanism, the device can be switched to another sampling bottle after one sampling bottle has been used to collect water samples. This allows for continuous sampling without moving the device away from the water source, thus improving sampling efficiency.

[0013] 2. By controlling the sampling bottle to draw water samples into its interior after it is opened underwater, it avoids the large suction force generated by a water pump, which would cause water to quickly gather at the pump input and agitate the water source. This avoids problems such as changes in the physical properties of the water, disruption of chemical balance, and interference with biological activity, thus preventing distortion of sample representativeness.

[0014] 3. The force transmission mechanism enables the sampling bottle to open when it reaches the sampling depth and close when sampling is finished, keeping the sampling bottle sealed. As a result, it will not come into contact with the outside world or water sources at different depths when it leaves the water, thus preventing water sample contamination, avoiding deviation of test results from the true value, and ensuring the accuracy of water sample test results.

[0025] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Please see the appendix Figure 1 - Appendix Figure 9 This invention provides a sample collection device for geological exploration engineering, including a mounting frame 1. A rotation and transformation mechanism 2 is provided on the top of the mounting frame 1, and a splicing mechanism 6 is provided on the top of the rotation and transformation mechanism 2. Force transmission mechanisms 3 are provided on both sides of the splicing mechanism 6. The rotation and transformation mechanism 2 and the force transmission mechanism 3 cooperate to replace the sampling container. A sampling mechanism 4 is provided on one side of the bottom of the rotation and transformation mechanism 2. The sampling mechanism 4 can control the sampling container to extract water samples. A disassembly and assembly mechanism 5 is rotatably connected to the middle of the mounting frame 1. The disassembly and assembly mechanism 5 can be used to install the sampling mechanism 4.

[0027] The rotating conversion mechanism 2 includes a mounting plate 201, which provides an installation position. The bottom of the mounting plate 201 is fixedly connected to the top of the mounting frame 1. A rotating groove 202 is provided inside the mounting plate 201. A mounting column 203 is rotatably connected to the top of the mounting plate 201. The mounting column 203 provides an installation position and can rotate on the mounting plate 201. A connecting plate 204 is fixedly connected to the outer side of the mounting column 203. The connecting plate 204 provides an installation position. An installation groove 205 is provided inside the connecting plate 204 on the side near the mounting column 203.

[0028] The mounting slot 205 provides an installation position. A tension spring 206 is installed inside the mounting slot 205. A limiting slide groove 210 is opened inside the connecting plate 204. The limiting slide groove 210 can provide a sliding position. A limiting slide post 207 is slidably connected inside the limiting slide groove 210. The limiting slide post 207 can slide inside the limiting slide groove 210 and can be driven to reset under the pull of the tension spring 206. A blocking plate 208 is fixedly connected to the top and middle of the limiting slide post 207. The blocking plate 208 can install the limiting slide post 207 inside the limiting slide groove 210. A pulley 209 is rotatably connected to the end of the connecting plate 204 away from the mounting post 203.

[0029] The pulley 209 can change the direction of the force of the force transmission mechanism 3. The bottom of the limiting slide 207 is set inside the rotating groove 202. Two blocking plates 208 are respectively set on the upper and lower sides of the connecting plate 204. One end of the tension spring 206 is fixedly connected to the inside of the mounting groove 205, and the other end of the tension spring 206 is fixedly connected to the side of the limiting slide 207 near the mounting post 203. When the mounting plate 201 needs to rotate, the force transmission mechanism 3 drives the limiting slide 207 to move away from the mounting post 203, so that the bottom of the limiting slide 207 can slide in the rotating groove 202. Since the trajectory of the limiting slide 207 is restricted by the connecting plate 204, when the bottom of the limiting slide 207 slides away from the mounting post 203, the bottom of the limiting slide 207 and the rotation groove 202 can be used to drive the mounting plate 201 to rotate.

[0030] When the limiting slide 207 moves to the side of the limiting slide groove 210 away from the mounting post 203, it can cause one corner of the rotating groove 202 to rotate to the bottom of the connecting plate 204. At this time, the limiting slide 207 has moved to the limit away from the mounting post 203. When the force transmission mechanism 3 is released, the limiting slide 207 is driven to move towards the mounting post 203 under the reaction force of the tension spring 206. Then, the bottom of the limiting slide 207 can move from one corner of the rotating groove 202 to the middle of the rotating groove 202, which can drive the mounting plate 201 to rotate. At this time, the mounting plate 201 can be rotated ninety degrees.

[0031] The force transmission mechanism 3 includes a mounting sleeve 301, which can be installed on the top of the splicing mechanism 6. The inner side of the mounting sleeve 301 is located on the top of the splicing mechanism 6. Fixing holes 302 are provided on both sides of the mounting sleeve 301. Fixing handles 303 are fixedly connected to the outside of the fixing holes 302. Fixing handles 303 can provide the installation position. A pinch handle 304 is rotatably connected to the bottom of the fixing handle 303. A mounting cylinder 305 is fixedly connected to the bottom of the fixing handle 303. The mounting cylinder 305 provides the installation position. A slider 306 is slidably connected inside the mounting cylinder 305. The slider 306 can be installed in the position and can slide inside the mounting cylinder 305. A return spring 307 is provided inside the mounting cylinder 305. The return spring 307 can push the slider 306 to return to its original position using its own reaction force.

[0032] A connecting rod 308 is rotatably connected to the bottom of the slider 306. The connecting rod 308 can drive the handle 304 to reset. The bottom end of the connecting rod 308 is rotatably connected to the top of the handle 304. A steel rope 309 is detachably connected to the bottom of the handle 304. The steel rope 309 can be replaced to adapt to splicing mechanisms 6 with different splicing numbers. The end of the steel rope 309 away from the handle 304 is detachably connected to the end of the limiting slide 207 away from the tension spring 206. The limiting slide 207 can be pulled by the steel rope 309. The outer side of one of the steel ropes 309 contacts the inner side of the pulley 209. The pulley 209 can change the direction of the force of the steel rope 309. One end of the reset spring 307 is fixedly connected to the inside of the mounting cylinder 305. The other end of the reset spring 307 is fixedly connected to one end of the slider 306. When installing the mounting sleeve 301, the mounting sleeve 301 is installed on the topmost splicing mechanism 6.

[0033] After the installation of the mounting sleeve 301 is completed, hold the fixing handle 303 and lift the pinch handle 304 upwards, which will drive the steel rope 309 upwards and use the connecting rod 308 to push the slider 306 away from the mounting sleeve 301. The slider 306 will compress the return spring 307. When the pinch handle 304 is released, the return spring 307 will push the slider 306 to return to its original position, and the connecting rod 308 will push the pinch handle 304 downwards. At this time, the steel rope 309 can also move downwards.

[0034] The sampling mechanism 4 includes multiple sampling bottles 411, all of which are located inside the mounting frame 1. The air inside the sampling bottles 411 is removed. After being placed in water, the water can be drawn into the sampling bottles 411, avoiding disturbance of the water source. This prevents the formation of high-concentration sediments in the bottom water due to long-term stagnation. Stirring would cause the upper water sample to mix with the bottom particulate matter, leading to deviations from the actual results in subsequent analysis. At the same time, it also avoids the introduction of air bubbles, which would attach to the surface of suspended matter or dissolve in the water. This prevents the introduction of air from increasing the dissolved oxygen content and interfering with the judgment of the redox state of the water. It also avoids disrupting the stratification, resulting in a mixed water layer that cannot reflect the true characteristics of the target layer.

[0035] An inner tube 412 is fixedly connected to the middle of the sampling bottle 411. The inner tube 412 provides an installation position. Multiple water inlet holes 413 are opened at the bottom of the inner tube 412, allowing water to enter the interior of the sampling bottle 411. A sliding plug 414 is slidably connected inside the inner tube 412. The sliding plug 414 can block the water inlet holes 413 to prevent air from entering the interior of the sampling bottle 411 and also to prevent water from flowing out of the interior of the sampling bottle 411 after water collection. A pull rope 415 is fixedly connected to the top of the sliding plug 414, which can pull the sliding plug 414 upward. A push spring 416 is provided inside the inner tube 412, which can push the sliding plug 414 to reset. One end of the push spring 416 is fixedly connected to the top of the interior of the inner tube 412, and the other end of the push spring 416 is fixedly connected to the top of the sliding plug 414.

[0036] A pole 417 is fixedly connected to the top of the pull rope 415. An anti-detachment plate 418 is fixedly connected to the top of the pole 417. A fixing plate 401 is fixedly connected to the outside of the mounting column 203. One side of the fixing plate 401 is fixedly connected to the outside of the mounting column 203. An installation groove 402 is provided inside the fixing plate 401. The installation groove 402 provides an installation position. A push-back spring 403 is provided inside the installation groove 402. The push-back spring 403 provides installation space. A connecting block 404 is slidably connected inside the installation groove 402. The connecting block 404 slides inside the push-back spring 403. A slide rod 405 is fixedly connected to the outside of the connecting block 404. The slide rod 405 provides an installation position. Limiting round plates 406 are fixedly connected to both the upper and lower ends of the slide rod 405. The limiting round plates 406 prevent the slide rod 405 from falling off the fixing plate 401.

[0037] The fixed plate 401 has a sliding groove 407 inside, which provides sliding space. The sliding rod 405 is slidably connected inside the sliding groove 407. The middle of the fixed plate 401 is rotatably connected to the pulley 408, which can change the direction of the force of the steel rope 309. The bottom of another steel rope 309 is detachably connected to the outside of the sliding rod 405. The outside of the steel rope 309 contacts the groove of the pulley 408. The bottom of the lower limiting circular plate 406 is fixedly connected to the bent rod 409, which serves as a connection. The bottom of the bent rod 409 is fixedly connected to the semi-circular sleeve 410. The cooperation between the upright rod 417 and the anti-detachment plate 418 can facilitate the locking of the semi-circular sleeve 410. One end of the push-back spring 403 is fixedly connected to the inside of the storage groove 402, and the other end of the push-back spring 403 is fixedly connected to one end of the connecting block 404.

[0038] When the steel rope 309 on the side away from the connecting plate 204 moves upward, it can drive the slide rod 405 to move towards the mounting post 203. The slide rod 405 can then drive the connecting block 404 to move towards the mounting post 203. This allows the connecting block 404 to compress and push back the spring 403, simultaneously driving the bent rod 409 and the semi-circular sleeve 410 towards the mounting post 203. They can then be secured to the outside of the upright post 417. The anti-detachment plate 418 is used to secure the top of the semi-circular sleeve 410, preventing the upright post 417 from detaching from the interior of the semi-circular sleeve 410. When the slide bar 405 continues to move towards the mounting post 203, it can use the semi-circular sleeve 410 to drive the upright 417 towards the mounting post 203, which in turn can pull the bottom of the pull rope 415 upward and drive the slide plug 414 upward. At this time, there is no object blocking the water inlet hole 413, and because the air inside the sampling bottle 411 is drawn away, the suction force can be generated in the inner tube 412 and the water inlet hole 413 under the action of air pressure difference, and water is quickly drawn into the sampling bottle 411 through the water inlet hole 413 to achieve water collection.

[0039] After one of the sampling bottles 411 has been collected, the handle 304 is released, and the steel rope 309 moves downward. At this time, the steel rope 309 has no tension. Under the action of the push spring 403, the connecting block 404 is pushed to move away from the mounting post 203, which can drive the slide rod 405 to move away from the mounting post 203. Then, the bent rod 409 and the semi-circular sleeve 410 can move away from the mounting post 203 and return to their original positions. When the upright rod 417 has no tension, it can drive the slide plug 414 to reset under the action of the push spring 416. This can pull the pull rope 415 to move downward and reset. Then, the slide plug 414 can be used to block the water inlet hole 413, so that the water sample collected in the sampling bottle 411 will not flow out of the sampling bottle 411. The rotation and transformation mechanism 2 is used to rotate 90 degrees to complete the conversion of the sampling bottle 411 and re-sampling.

[0040] The disassembly and assembly mechanism 5 includes a fixed cylinder 501, which provides an installation position. The top of the fixed cylinder 501 is fixedly connected to the middle of the mounting plate 201. A limiting sliding plate 502 is slidably connected inside the fixed cylinder 501, which has a limiting function. An internal connecting column 503 is fixedly connected to the bottom of the limiting sliding plate 502, which has a connecting function. A high-pressure spring 504 is provided inside the fixed cylinder 501. The high-pressure spring 504 can drive the limiting sliding plate 502 to move upward and can drive the internal connecting column 503 to reset. A base frame 505 is fixedly connected to the bottom of the internal connecting column 503. One end of the high-pressure spring 504 is fixedly connected to the bottom of the limiting sliding plate 502, and the bottom of the high-pressure spring 504 is fixedly connected to the bottom of the inside of the fixed cylinder 501. The high-pressure spring 504 is sleeved on the outside of the internal connecting column 503, and the bottom of the internal connecting column 503 penetrates the bottom of the fixed cylinder 501.

[0041] When the sampling bottle 411 is removed after water collection, the base frame 505 is moved away from the mounting frame 1, which in turn pulls the internal connecting column 503 away from the mounting frame 1, causing the limiting sliding plate 502 to move downward. The limiting sliding plate 502 compresses the force spring 504. After the top of the sampling bottle 411 leaves the interior of the mounting frame 1, the sampling bottle 411 can be removed from the interior of the base frame 505. When installing an empty sampling bottle 411, the bottom of the empty sampling bottle 411 can be placed inside the interior of the base frame 505, and the base frame 505 is released. At this time, under the action of the force spring 504, the limiting sliding plate 502 can be pushed upward, which can drive the internal connecting column 503 to move upward, thereby driving the base frame 505 to move upward and clamping the sampling bottle 411 between the mounting frame 1 and the base frame 505, thus realizing the installation of the sampling bottle 411.

[0042] The splicing mechanism 6 includes multiple splicing tubes 601 and multiple splicing blocks 603. The bottom of each splicing tube 601 is placed outside the splicing block 603 to allow for splicing. The bottoms of the multiple splicing blocks 603 are respectively fixedly connected to the mounting post 203 and the tops of the multiple splicing tubes 601. Splicing holes 602 are provided on both sides of the bottom of each splicing tube 601. Two receiving grooves 604 are provided inside the top of each splicing block 603, providing an installation position. A locking spring 605 is installed inside each receiving groove 604, and a limiting plate 606 is slidably connected inside the receiving groove 604, serving a limiting function. A locking head 607 is fixedly connected to the end of the limiting plate 606 away from the locking spring 605. The locking head 607 can lock into the inside of the splicing hole 602, so that the spliced ​​splicing tube 601 cannot be easily separated. When it is necessary to separate the spliced ​​splicing tube 601, simply press the locking head 607 into the inside of the receiving groove 604, so that the splicing tube 601 can be pulled out of the outside of the splicing block 603. The locking head 607 locks into the splicing hole 602. One end of the locking spring 605 is fixedly connected to the inside of the receiving groove 604, and the other end of the locking spring 605 is fixedly connected to the end of the limiting plate 606 away from the locking head 607.

[0043] When splicing the splicing pipe 601, first press the two locking heads 607 towards the center, causing the limiting plate 606 to move towards the center and compress the locking spring 605. After the locking head 607 moves into the receiving groove 604, place another splicing pipe 601 outside the splicing block 603 and align the splicing hole 602 with the locking head 607. When the splicing hole 602 moves to the locking head 607, the limiting plate 606 moves outward under the action of the locking spring 605, which in turn moves the locking head 607 outward, so that the locking head 607 engages inside the splicing hole 602. This allows multiple splicing pipes 601 to be spliced, and different numbers of splicing pipes 601 can be spliced ​​depending on the water depth and the depth of water collected.

[0044] Working principle: When the mounting plate 201 rotates, it pulls the steel cable 309, which in turn drives the limiting slide 207 to move away from the mounting column 203. This allows the bottom of the limiting slide 207 to slide in the rotating groove 202. Since the trajectory of the limiting slide 207 is restricted by the connecting plate 204, when the bottom of the limiting slide 207 slides away from the mounting column 203, the restriction of the bottom of the limiting slide 207 and the rotating groove 202 can drive the mounting plate 201 to rotate.

[0045] When the limiting slide 207 moves to the side of the limiting slide groove 210 away from the mounting post 203, it can cause one corner of the rotating groove 202 to rotate to the bottom of the connecting plate 204. At this time, the limiting slide 207 has moved to the limit away from the mounting post 203. When the steel cable 309 is released, the limiting slide 207 is driven to move towards the mounting post 203 under the reaction force of the tension spring 206. Then, the bottom of the limiting slide 207 can move from one corner of the rotating groove 202 to the middle of the rotating groove 202, which can drive the mounting plate 201 to rotate. At this time, the mounting plate 201 can be rotated ninety degrees.

[0046] When installing the mounting sleeve 301, press the engaging head 607 towards the center, causing it to retract into the receiving groove 604. Place the mounting sleeve 301 onto the uppermost splicing block 603. When the fixing hole 302 moves to the position of the engaging head 607, the splicing pipe 601 can be installed onto the uppermost splicing block 603 under the reaction force of the engaging spring 605, thus completing the installation of the mounting sleeve 301. At this time, grasp the fixing handle 303 and lift the pinch handle 304 upward, which can drive the steel rope 309 upward. The connecting rod 308 pushes the slider 306 to move away from the mounting sleeve 301, and the slider 306 compresses the return spring 307. When the pinch handle 304 is released, the return spring 307 can push the slider 306 to return to its original position, and the connecting rod 308 can push the pinch handle 304 downward. At this time, the steel rope 309 can also move downward.

[0047] When the steel rope 309 on the side away from the connecting plate 204 moves upward, it can drive the slide rod 405 to move towards the mounting post 203. The slide rod 405 can then drive the connecting block 404 to move towards the mounting post 203. This allows the connecting block 404 to compress and push back the spring 403, simultaneously driving the bent rod 409 and the semi-circular sleeve 410 towards the mounting post 203. They can then be secured to the outside of the upright post 417. The anti-detachment plate 418 is used to secure the top of the semi-circular sleeve 410, preventing the upright post 417 from detaching from the interior of the semi-circular sleeve 410. When the slide bar 405 continues to move towards the mounting post 203, it can use the semi-circular sleeve 410 to drive the upright 417 towards the mounting post 203, which in turn can pull the bottom of the pull rope 415 upward and drive the slide plug 414 upward. At this time, there is no object blocking the water inlet hole 413, and because the air inside the sampling bottle 411 is drawn away, the suction force can be generated in the inner tube 412 and the water inlet hole 413 under the action of air pressure difference, and water is quickly drawn into the sampling bottle 411 through the water inlet hole 413 to achieve water collection.

[0048] After one of the sampling bottles 411 has been collected, the handle 304 is released, and the steel rope 309 moves downward. At this time, the steel rope 309 has no tension. Under the action of the push spring 403, the connecting block 404 is pushed to move away from the mounting post 203, and the sliding rod 405 is moved away from the mounting post 203. Then, the bent rod 409 and the semi-circular sleeve 410 are moved away from the mounting post 203 and return to their original positions. When the upright rod 417 has no tension, it can drive the sliding plug 414 to reset under the action of the push spring 416. This allows the pull rope 415 to move downward and reset. Then, the sliding plug 414 can be used to block the water inlet 413, so that the water sample collected in the sampling bottle 411 will not flow out of the sampling bottle 411. The rotation and transformation mechanism 2 is used to rotate 90 degrees to complete the conversion of the sampling bottle 411 and re-sample.

[0049] When the sampling bottle 411 is removed after water collection, the base frame 505 is moved away from the mounting frame 1, which in turn pulls the internal connecting column 503 away from the mounting frame 1 and causes the limiting sliding plate 502 to move downward. The limiting sliding plate 502 compresses the force spring 504. After the top of the sampling bottle 411 leaves the interior of the mounting frame 1, the sampling bottle 411 can be removed from the interior of the base frame 505. When installing an empty sampling bottle 411, the bottom of the empty sampling bottle 411 can be placed inside the interior of the base frame 505 and the base frame 505 is released. At this time, under the action of the force spring 504, the limiting sliding plate 502 can be pushed upward, which can drive the internal connecting column 503 to move upward, thereby driving the base frame 505 to move upward and clamping the sampling bottle 411 between the mounting frame 1 and the base frame 505, thus realizing the installation of the sampling bottle 411.

[0050] When splicing the splicing pipe 601, first press the two locking heads 607 towards the center, causing the limiting plate 606 to move towards the center and compress the locking spring 605. After the locking head 607 moves into the receiving groove 604, place another splicing pipe 601 outside the splicing block 603 and align the splicing hole 602 with the locking head 607. When the splicing hole 602 moves to the locking head 607, the limiting plate 606 moves outward under the action of the locking spring 605, which in turn moves the locking head 607 outward, so that the locking head 607 engages inside the splicing hole 602. This allows multiple splicing pipes 601 to be spliced, and different numbers of splicing pipes 601 can be spliced ​​depending on the water depth and the depth of water collected.

[0051] It should be noted that when applying the geological exploration engineering sample collection device provided in the embodiments of the present invention to different scenarios, in order to facilitate the smooth lowering of the sample collection device for sampling operations, please refer to... Figure 1 The maximum distance 2R between the two ends of the base frame 505 can be adjusted according to actual needs. For example, the opening diameter of conventional hydrogeological boreholes is usually 146mm to 325mm, mainly used in loose strata or complex strata requiring casing protection. In this case, the 2R (bore radius) can be designed to be 120mm to 300mm. In conventional exploration-production combined boreholes, the opening diameter in loose strata is generally ≥108mm, so the 2R can be designed to be ≥80mm. The final diameter of conventional exploration boreholes is mostly 110mm (for full coring) or less than 200mm, so the 2R can be designed to be 80mm or less than 175mm. In conventional pumping test boreholes, the final diameter in loose strata is ≥108mm, and after enlargement, it needs to be ≥450mm to meet the gravel filling requirements. In this case, the 2R can be designed to be ≥80mm or more, or ≥420mm after enlargement. For conventional observation boreholes, the final diameter in loose strata is ≤200mm, and in bedrock strata is ≤150mm. In this case, the 2R can be designed to be less than 170mm (for loose strata) or less than 120mm (for bedrock strata).
