Description

Technical Field

[0001] The present invention relates to the technical field of water source sampling and detection, and specifically provides a water source sampling and detection device for geological exploration. Background Art

[0002] When sampling and detecting water sources during geological exploration, water source sampling is generally carried out in groundwater environment detection wells. When sampling deeper water sources, the sampler is generally sent into the water by means of suspension and pulling for sampling. For example, a Chinese patent with the authorization announcement number CN216247357U discloses a water source sampling and detection device for hydrogeological exploration, including a main frame. By setting a ratchet and a pawl, when the user conducts water collection and sampling, it can stop immediately at any depth, avoiding excessive sinking of the water collection device. By setting a float and a scale rope, the user can accurately judge the depth where the water collection device is located, improving the accuracy of the sampling result and reducing the operation difficulty.

[0003] During water source sampling, the sampling device is extended into the water through a pulling rope. Similar to the above-mentioned prior art, when sampling water sources at deeper positions in a water environment detection well, the sampling device needs to be extended into deeper water. In order to accurately sample water samples at a specific depth, the water intake hole of the sampling device needs to be extended to a specific depth, and then the water intake is opened through the cooperation of an external detection device, a wireless transmitter, and a controller, and then closed. The water environment detection well is in a long-term water-containing state, and more attachments are likely to accumulate on the upper layer of the water source. When the water intake device is placed in the water, the attachments located on the upper layer of the water source are easily adhered to the periphery of the water intake device. When the water intake hole is opened for water intake subsequently, impurities on the upper layer are likely to enter, affecting water quality detection. Summary of the Invention

When the electric push rod 10 works, it drives the rotating housing 14 to rotate, causing the sampling bucket 13 to move successively through section a, section b, section c, and section d of the sealing plate 12 (when the sampling bucket 13 is in section a of the sealing plate 12, the water inlet hole 28 communicates with the through hole 18, and it is in the water intake stage; when the electric push rod 10 works, it controls the sampling bucket 13 to move to section b of the sealing plate 12. At this time, the water inlet hole 28 is misaligned with the through hole 18, and it is in the stage of pulling up or lowering the collection housing 1; the electric push rod 10 continues to work, controlling the sampling bucket 13 to move to section c of the sealing plate 12 and communicate with the connection hole 11. During the movement, the water inlet hole 28 and the through hole 18 are still misaligned, and at the same time, it controls the sealing annular plate 24 to move, causing the detection port 23 to communicate with the guiding holes 27. At this time, the detection port 23, the guiding holes 27, the connection hole 11, and the sampling bucket 13 are communicated, and it is in the detection stage; the electric push rod 10 continues to work, and when the sampling bucket 13 is controlled to move to section d of the sealing plate 12, the liquid outlet hole 9 at the bottom of the sampling bucket 13 communicates with the drain hole 17, and it is in the drainage stage).

[0035] As a further technical solution of the present invention, a plurality of groups of meshing first gears 25 are rotatably installed at the upper end of the collection housing 1. A semi-circular plate 22 for sealing the detection port 23 is fixedly installed on one side of the first gear 25. A second gear 26 is fixedly connected to the lower end of one of the first gears 25. A plurality of engaging teeth 29 meshing with the second gear 26 are fixedly installed inside the sealing annular plate 24. The detection port 23 has a certain depth and there will be accumulated water. It can be sealed by the semi-circular plate 22 to prevent the detection probe from contacting other water sources when inserted during detection, affecting the detection result.

[0036] Working principle:

[0037] At the beginning, the sampling bucket 13 is in section b of the sealing plate 12 (at this time, the liquid outlet hole 9 is misaligned with the drain hole 17, the water inlet hole 28 is misaligned with the through hole 18, the upper end of the sampling bucket 13 is in a sealed state, the second gear 26 and the engaging teeth 29 are not meshed, and the detection port 23 is in a closed state):

[0038] The collection housing 1 is sent into the water through the pull rope 7. After being sent to a certain depth, the electric push rod 10 is started to drive the slide rod 19 to move upward. Through the cooperation of the spiral groove 16 and the slide rod 19, the connecting ring 15 is driven to rotate. The connecting ring 15 drives the rotating housing 14 to rotate. The rotating housing 14 drives the rotating frame 5 to rotate. The rotating frame 5 drives the rotating gear ring 4 to rotate. The rotating gear ring 4 drives the connecting gear ring 8 to rotate. The connecting gear ring 8 drives the filter screen barrel 3 to rotate (the sampling barrel 13 is in a rotating state during the process of moving to the a section, b section, c section, and d section of the sealing plate 12). The attachments on the outer side of the filter screen barrel 3 are scraped off by the scraper 6.

[0039] The rotating housing 14 rotates (the rotating housing 14 will also drive the sealing annular plate 24 to move, and the second gear 26 and the engaging teeth 29 are not engaged), driving a plurality of sampling barrels 13 to move, and moving the sampling barrel 13 to the a section of the sealing plate 12 (the water inlet hole 28 is communicated with the through hole 18, in the water intake stage). Before the water inlet hole 28 is communicated with the through hole 18, the attachments on the outer side of the filter screen barrel 3 can be scraped off to prevent the filter screen barrel 3 from being blocked and affecting the water source sampling.

[0040] After the sampling of the sampling barrel 13 located at the a section of the sealing plate 12 is completed, the electric push rod 10 drives the slide rod 19 to move downward and reset, so that the sampling barrel 13 is located at the b end of the sealing plate 12, and the collection housing 1 is pulled out through the pull rope 7.

[0041] Then, control the electric push rod 10 to drive the slide rod 19 to continue to move downward, driving the rotating housing 14 to move, and moving the sampling barrel 13 to the c section of the sealing plate 12. During the movement, the water inlet hole 28 is misaligned with the through hole 18, the detection port 23, the guiding hole 27, the connecting hole 11, and the sampling barrel 13 are communicated, and at the same time, the second gear 26 and the engaging teeth 29 are engaged, causing the second gear 26 to rotate. Through the cooperation of multiple groups of first gears 25, the semi-circular plate 22 is driven to move, opening the detection port 23, and a detection probe can be inserted into the sampling barrel 13 through the detection port 23.

[0042] After the detection is completed, continue to start the electric push rod 10 to drive the slide rod 19 to continue to move downward, driving the rotating housing 14 to move, and moving the sampling barrel 13 to the d section of the sealing plate 12. During the movement, the second gear 26 and the engaging teeth 29 are not engaged. After the movement is completed, the liquid outlet hole 9 is communicated with the drain hole 17, and the water in the sampling barrel 13 can be poured out. Then, start the electric push rod 10 to reset the sampling barrel 13 to the b section of the sealing plate 12.
