Description

TECHNICAL FIELD

[0001] The utility model relates to the field of water quality monitoring, specifically to a water quality monitoring sample collection device. BACKGROUND

[0002] Water quality monitoring is the process of monitoring and measuring the types of pollutants in water bodies, the concentrations of various pollutants and their trends, and evaluating water quality. The monitoring range is very wide, including both unpolluted and polluted natural water (rivers, lakes, seas and groundwater) and various industrial wastewater. During the water quality monitoring process, a corresponding sample collection device is usually used to collect samples from the monitored water area. The collected water samples can be qualitatively and quantitatively analyzed in the laboratory to reflect the stage characteristics and evolution trend of water quality, providing a strong basis for water quality monitoring.

[0003] According to the patent with the publication number CN218392441U, a water quality monitoring sample collection device is disclosed. The utility model improves the collection efficiency of water samples by cleaning the filter screen, ensuring stable water flow, and achieving precise collection of water samples from different areas, ensuring the integrity of the water samples.

[0004] According to the above-mentioned patent content, the blade, shaft and scraper are provided to allow the blade to rotate when impacted by the water flow, thereby driving the scraper to rotate and allowing the scraper to remove foreign matter attached to the filter screen, preventing the filter screen from being blocked. However, since there are solid impurities in the water, when the solid impurities in the water are stuck in the mesh holes of the filter screen, the blade will rotate even if it is impacted by the water flow, and the scraper will also rotate. When the scraper collides with the impurities stuck in the mesh holes, it is difficult to remove the impurities stuck in the mesh holes, so the impurities remain stuck in the mesh holes, and the leakage point of the impurities may block the scraper, making it difficult for the scraper to continue rotating, thereby reducing the cleaning efficiency of the filter screen. UTILITY MODEL CONTENT

[0005] Therefore, the utility model aims to provide a water quality monitoring sample collection device to solve the technical problem of not being able to clean the impurities stuck in the filter screen mesh holes.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a water quality monitoring sample collection device, comprising a collection cylinder and a limiting ring. A threaded column is installed at the top center of the collection cylinder. A limiting nut and a retaining plate are respectively fitted on the outer wall of the threaded column. A retaining groove is opened on one side of the top of the limiting ring. A fixing ring is installed on the outer wall of the collection cylinder, and a side plate is fixed on one side of the fixing ring. A threaded rod is installed on the top of the side plate, and a threaded cylinder is fitted on the outer wall of the threaded rod. A sealing disc is provided at the bottom of the collection cylinder. Guide rods are installed on both sides of the bottom of the sealing disc, and a movable frame is fitted between the two guide rods. A threaded hole is opened inside the threaded column. A threaded shaft is threadedly connected inside the threaded hole, and the bottom end of the threaded shaft passes through the sealing disc and is connected to the top of the movable frame through a bearing. Multiple unblocking rods are installed at the bottom of the movable frame.

[0007] By adopting the above technical solution, when it is necessary to insert the collection tube into the water, the threaded rod can be held and the threaded tube can be rotated to move the threaded rod out of the threaded tube, and then the collection tube can be lowered.

[0008] Furthermore, a sealing disc is provided at the bottom of the inside of the collection tube, and two through holes are opened on the top of the sealing disc, on which two sample tubes are placed.

[0009] By adopting the above technical solution, the through hole design facilitates the first one-way valve to pass through the sealing disc.

[0010] Furthermore, a first one-way valve with a through hole is installed at the bottom of the sample tube, a top cover is threaded to the top of the sample tube, a second one-way valve is installed on the top of the top cover, and a limiting ring is provided on the outer wall of the top cover.

[0011] By adopting the above technical solution, the first one-way valve allows water to enter the sample tube and prevents water in the sample tube from flowing back through the first one-way valve.

[0012] Furthermore, insertion holes are provided on both sides of the top of the collection tube, and the sample tube passes through the insertion holes.

[0013] By adopting the above technical solution, the through hole facilitates the placement and removal of sample tubes.

[0014] Furthermore, a filter plate is bolted to the bottom of the collection cylinder, and the filter plate has multiple water passage holes. The outer wall of the threaded cylinder is provided with an anti-slip sleeve.

[0015] By adopting the above technical solution, the filter plate can filter impurities in the water entering the collection tube, preventing large particles of impurities from entering the sample tube.

[0016] Furthermore, the bottom of the limiting nut is fitted against the top of the clamping plate.

[0017] By adopting the above technical solution, the limiting nut can tighten the clamping plate and prevent it from moving at will.

[0018] Furthermore, the two sides of the card plate are located inside the two card slots.

[0019] By adopting the above technical solution, after the card plate is moved into the card slot, it can tighten and limit the limiting ring and limit the sample tube to prevent the sample tube from moving at will.

[0020] Furthermore, a sealing ring is provided on the side of the limiting ring that is in contact with the top of the collection tube, and the diameter of the limiting ring is larger than the diameter of the insertion hole.

[0021] By adopting the above technical solution, the limiting ring can be used to seal the insertion hole.

[0022] Furthermore, sealing rings are installed at the top of the threaded cylinder and the bottom of the sealing disc, and the outer wall of the threaded shaft fits against the inner walls of the two sealing rings.

[0023] By adopting the above technical solution, water can be prevented from flowing into the inside of the collection tube from the gap between the threaded shaft and the sealing disc or threaded cylinder, thereby improving the sealing effect of the collection tube.

[0024] Furthermore, the number of the unblocking rods is the same as the number of water holes, the unblocking rods are located directly above the water holes, and the unblocking rods correspond one-to-one with the water holes.

[0025] By adopting the above technical solution, when the unblocking rod is moved into the corresponding water hole, it can push the impurities blocking the water hole downward, so that the impurities are removed from the water hole, thereby achieving the purpose of unblocking the water hole.

[0026] In summary, the present invention has the following main advantages:

[0027] 1. This utility model, by comprising a threaded shaft, a threaded hole, a drain rod, and a movable frame, allows for unblocking of a water passage when impurities are found to be clogging the passage. The operator rotates the threaded shaft, causing it to move downwards, which in turn moves the movable frame downwards. The movable frame then moves the drain rod downwards, allowing it to extend into the water passage and push out the clogging impurities. This unblocks the passage, preventing impurities from remaining stuck and difficult to remove, thus improving the efficiency of unblocking. After unblocking, the threaded shaft is rotated in the opposite direction, causing the movable frame to move the drain rod upwards to its original position.

[0028] 2. This utility model is equipped with guide rods to guide the movable frame, prevent the movable frame from rotating, enable the movable frame to smoothly drive the unblocking rod up and down, and improve the stability of the movable frame when it moves.

[0029] 3. This utility model, by setting up a clamping plate, a clamping groove, a threaded post, and a limiting nut, allows the following operation: When the sample tube is inserted into the collection tube and the bottom of the limiting ring is in contact with the top of the collection tube, the operator first pushes the rotating plate upward, causing it to move on the threaded post. Then, the clamping plate is rotated so that both sides of the clamping plate are directly above the clamping groove. The clamping plate is then pushed downward, causing it to engage inside the clamping groove, thereby limiting the limiting ring and preventing the sample tube from shaking freely, thus improving the stability of the sample tube. Next, the limiting nut is rotated so that the bottom of the limiting nut is in contact with the top of the clamping plate, thus limiting the clamping plate and preventing it from moving out of the clamping groove, thereby improving the stability of the clamping plate.

[0038] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0039] The embodiments of this utility model will be described below based on its overall structure.

[0040] Example 1:

[0041] A water quality monitoring sample collection device, such as Figures 1-7 As shown, the device includes a collection cylinder 1 and a limiting ring 13. A threaded post 14 is installed at the top center of the collection cylinder 1. A limiting nut 15 and a retaining plate 16 are respectively fitted on the outer wall of the threaded post 14. A retaining groove 17 is opened on one side of the top of the limiting ring 13. A fixing ring 2 is installed on the outer wall of the collection cylinder 1, and a side plate 3 is fixed on one side of the fixing ring 2. A threaded rod 4 is installed on the top of the side plate 3, and a threaded cylinder 5 is fitted on the outer wall of the threaded rod 4. When it is necessary to insert the collection cylinder 1 into the water, the threaded rod 4 can be held and the threaded cylinder 5 can be rotated to move the threaded rod 4 out of the threaded cylinder 5, and then the collection cylinder 1 can be lowered.

[0042] Specifically, a sealing plate 6 is provided at the bottom of the inside of the collection tube 1. The top of the sealing plate 6 has two through holes 18, and two sample tubes 8 are placed on the top of the sealing plate 6. The through holes 18 allow the first one-way valve 9 to pass through the sealing plate 6. The bottom of the sample tube 8 is equipped with the first one-way valve 9 that passes through the through holes 18. The top of the sample tube 8 is threadedly connected to a top cover 11, and a second one-way valve 12 is installed on the top of the top cover 11. The outer wall of the top cover 11 is provided with a limiting ring 13. The first one-way valve 9 allows water to enter the sample tube 8 and prevents water in the sample tube 8 from flowing back through the first one-way valve 9. The second one-way valve 12 allows water in the sample tube 8 to flow out, while water outside the collection tube 1 cannot enter the sample tube 8 through the second one-way valve 12. Insertion holes 19 are provided on both sides of the top of the collection tube 1, and the sample tubes 8 pass through the insertion holes 19. The through holes 18 facilitate the placement and removal of the sample tubes 8.

[0043] Specifically, the bottom of the limiting nut 15 fits against the top of the clamping plate 16, and the limiting nut 15 can tighten the clamping plate 16 to prevent it from moving at will. The two sides of the clamping plate 16 are located inside the two clamping slots 17. After the clamping plate 16 moves into the clamping slots 17, it can tighten and limit the limiting ring 13 and limit the sample tube 8 to prevent it from moving at will. The side of the limiting ring 13 that fits against the top of the collection tube 1 is provided with a sealing ring. The diameter of the limiting ring 13 is larger than the diameter of the insertion hole 19 so that the limiting ring 13 can seal the insertion hole 19.

[0044] See Figures 1-5A filter plate 10 is bolted to the bottom of the collection tube 1. The filter plate 10 has multiple water passage holes 24. The filter plate 10 filters impurities in the water entering the collection tube 1, preventing large particles from entering the sample tube 8. Guide rods 20 are installed on both sides of the bottom of the sealing disc 6, and a movable frame 21 is sleeved between the two guide rods 20. The movable frame 21 is slidably connected to the guide rods 20, and the guide rods 20 guide the movable frame 21, improving its stability during movement. A threaded hole 25 is opened inside the threaded column 14, and a threaded shaft 23 is threadedly connected inside the threaded hole 25. The bottom end of the threaded shaft 23 passes through the sealing disc 6 and... The bearing is connected to the top of the movable frame 21. Multiple unblocking rods 22 are installed at the bottom of the movable frame 21. The number of unblocking rods 22 is the same as the number of water holes 24. The unblocking rods 22 are located directly above the water holes 24. The unblocking rods 22 correspond one-to-one with the water holes 24. When the unblocking rod 22 moves into the corresponding water hole 24, it can push the impurities blocking the water hole 24 downward, so that the impurities are removed from the water hole 24, thereby achieving the purpose of unblocking the water hole 24. Silicone rings 27 are installed on both sides of the top of the sealing plate 6. The top of the silicone ring 27 fits against the bottom of the sample tube 8, improving the sealing between the bottom of the sample tube 8 and the sealing plate 6.

[0045] Example 2:

[0046] Based on the above embodiment 1, in order to improve the sealing performance between the threaded cylinder 5 and the threaded shaft 23, the following structure will be set.

[0047] Specifically, sealing rings 26 are installed on the top of the threaded cylinder 5 and the bottom of the sealing disc 6. The outer wall of the threaded shaft 23 fits against the inner wall of the two sealing rings 26, which can prevent water from flowing into the inside of the collection cylinder 1 from the gap between the threaded shaft 23 and the sealing disc 6 or the threaded cylinder 5, thereby improving the sealing effect of the collection cylinder 1.

[0048] Example 3:

[0049] Based on the above embodiment 1, the following structure will be set to facilitate the rotation of the threaded cylinder 5.

[0050] See Figures 1-2 The outer wall of the threaded cylinder 5 is provided with an anti-slip sleeve 7, which makes it convenient for workers to rotate the threaded cylinder 5, thereby allowing the threaded rod 4 to be moved out of the inside of the threaded cylinder 5.

[0051] The working principle of this utility model is as follows: First, when the device is to be used, two sample tubes 8 are inserted into the collection tube 1 through the insertion hole 19. After insertion, the bottom of the limiting ring 13 will be in contact with the top of the collection tube 1. Then, push the card plate 16 upward so that the card plate 16 moves on the threaded post 14. Then rotate the card plate 16 so that both sides of the card plate 16 are rotated to the top of the slot 17. Then push the card plate 16 downward so that the card plate 16 is inserted into the slot 17 and thus limits the limiting ring 13, preventing the sample tubes 8 from shaking randomly.

[0052] Then, the staff holds the threaded cylinder 5 and submerges the collection cylinder 1 in the water. When it is necessary to remove the threaded rod 4 from the threaded cylinder 5, the staff can hold the threaded rod 4 and rotate the threaded cylinder 5 to remove the threaded rod 4 from the threaded cylinder 5. Then the collection cylinder 1 can continue to be lowered. As the collection cylinder 1 is submerged in the water, the water will flow upward from the water passage 24 at the bottom of the filter plate 10 into the collection cylinder 1. Then it will enter the sample tube 8 through the first one-way valve 9. The air and excess water in the sample tube 8 can be discharged through the second one-way valve 12. In this way, the water sample can be collected.

[0053] After the collection is completed and the collection tube 1 is lifted out of the water, if it is found that impurities are blocking the water passage hole 24 and it is necessary to clear the water passage hole 24, the staff can rotate the threaded shaft 23, causing the threaded shaft 23 to move down, which in turn causes the movable frame 21 to move down. The movable frame 21 then causes the clearing rod 22 to move down, so that the clearing rod 22 extends into the water passage hole 24 and pushes out the impurities blocking the water passage hole 24, thereby clearing the water passage hole 24. After clearing, rotate the threaded shaft 23 in the opposite direction, so that the movable frame 21 drives the clearing rod 22 to move up and reset.
