Description

Technical Field

[0001] This invention relates to the field of water body sample collection technology, specifically to a hydrological water body sample collection device and method. Background Technology

[0002] There are many causes of water pollution, such as domestic sewage and industrial wastewater. If polluted water is not treated in a timely and effective manner or is discharged indiscriminately, it will cause significant damage to soil and water sources. Therefore, it is necessary to purify polluted water. Before water purification, it is generally necessary to take samples of the polluted water and then test the samples to understand the basic situation of water pollution, and then make a scientific design for water purification.

[0003] A search revealed patent number CN217980875U, which discloses a water sampling device. By connecting the lifting line to the pulleys on the fixed pulley assembly, the device can support and steer the lifting line, reducing wear and swaying, and providing a certain degree of vibration protection. By controlling the forward and reverse rotation of the output shaft of the first servo motor, the translation plate can be moved left and right based on the positioning slide rod, thereby driving the water sampling tube to sample different water areas, improving the multi-point sampling and making the sampling results more scientific. However, existing hydrological water sample sampling devices still have certain defects in use. After sampling water at one location, the existing devices immediately retract the sampling device and pour the sample into the storage device before sampling water at other locations again. The operation is relatively complicated, greatly increasing the workload of the staff and reducing work efficiency. Therefore, a hydrological water sample sampling device and method are proposed.

[0014] A method for sampling hydrological water bodies, the specific steps of which are as follows:

[0015] Step 1: The main body of the equipment is moved above the water body by the rotors on the upper side of the four sets of connecting rods. After the main body of the equipment reaches the target position, the winding motor at one end of the mounting plate is started to drive the winding rod to rotate, thereby driving the lifting rope and the four sets of connecting ropes to be lowered. This causes the lifting shell to move away from the main body of the equipment and sink into the water body to complete the water sampling process at different points.

[0016] Step 2: Start the first motor inside the first housing to drive the first rotating shaft and the rotating disk to rotate together, thereby driving several sets of bearing plates to rotate until the sampling tube is connected to the water guide pipe. At this time, the first magnetic ring and the second magnetic ring move away from each other due to the repulsion of like charges, and open the solenoid valve inside the fixed ring plate to allow water to enter the interior of the sampling tube. Then close the solenoid valve. When the lifting shell changes position, the rotating disk is rotated again, and the above operation is repeated to continue sampling to complete the water classification sampling process.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] 1. By starting the first motor inside the first housing, the first rotating shaft and the rotating disk rotate together, thereby rotating several sets of support plates until the sampling tube on one set of support plates is connected to the water guide pipe on the bottom baffle. At this time, the first magnetic ring and the second magnetic ring move away from each other due to the repulsion of like charges, and the solenoid valve inside the fixed ring plate is opened, allowing water to enter the interior of the sampling tube. After sampling, the solenoid valve is closed. When the position of the lifting shell changes, the rotating disk is rotated again, and sampling continues in the same way. At the same time, the second motor inside the second housing is started to drive the second rotating shaft to rotate, thereby driving the four sets of bottom scrapers and four sets of side scrapers to rotate together to scrape off the blockage on the outside of the filter screen. This allows for the classification, storage, and sampling of water from multiple points without preventing equipment blockage, reducing the workload of staff and significantly improving water sampling efficiency.

[0019] 2. Pass the second fastening bolt through the threaded hole of the connecting ring and connect it to the main body of the equipment. At this time, all four sets of connecting rods are installed at the corners of the main body of the equipment. Then, the rotors on the upper side of the four sets of connecting rods allow the main body of the equipment to move above the water. After the main body of the equipment reaches the target position, start the winding motor at one end of the mounting plate to drive the winding rod to rotate, thereby driving the lifting rope and the four sets of connecting ropes to be lowered. This causes the lifting shell to move away from the main body of the equipment and sink into the water. It can sample water at different depths at different positions above the water, expanding the water sampling range and having good applicability.

[0020] 3. By starting the lead motor at one end of the mounting slot, the threaded shaft is rotated. This rotation, through the threaded connection between the threaded shaft and the moving block, causes the moving block to slide inside the mounting slot. The guide tube, in conjunction with the strip opening, neatly arranges the lifting rope on the outside of the winding rod, preventing it from getting stuck in the equipment. Simultaneously, the first and second shafts ensure that both the first and second movable tubes are in rolling contact with the lifting rope, preventing friction damage during winding and extending its service life.

[0031] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0032] Please see Figures 1 to 8 This invention provides a hydrological water body sample collection device and method, the technical solution of which is as follows:

[0035] Specifically, the second fastening bolt 47 is threaded through the connecting ring 8 and threaded through the threaded hole 48 to connect with the main body 1. At this time, the four sets of connecting rods 9 are installed at the corners of the main body 1. Then, the rotors 10 on the upper side of the four sets of connecting rods 9 allow the main body 1 to move above the water. After the main body 1 reaches the target position, the winding motor 3 at one end of the mounting plate 2 is started to drive the winding rod 4 to rotate, thereby driving the lifting rope 5 and the four sets of connecting ropes 7 to be lowered. This causes the lifting shell 6 to continuously move away from the main body 1 and sink into the water.

[0038] A filter screen housing 26 is provided on the lower side of the bottom baffle 18. A second housing 27 is fixedly installed in the middle of the inner bottom surface of the filter screen housing 26. A second motor 28 is fixedly installed in the inner side of the second housing 27. A second rotating shaft 29 that passes through the filter screen housing 26 is fixedly connected to the output end of the second motor 28. Four sets of bottom scraper rods 30 are fixedly connected to the bottom of the outer side of the second rotating shaft 29. Side scraper plates 31 are fixedly connected to the outer ends of the four sets of bottom scraper rods 30.

The four sets of bottom scraper rods 30 are evenly distributed on the lower surface of the filter screen housing 26, and the four sets of side scraper plates 31 are evenly distributed on the outer side of the filter screen housing 26.

An externally threaded rod 50 is fixedly connected to the middle of the lower surface of the bottom baffle 18, and the externally threaded rod 50 is threadedly connected to the internally threaded tube 51.

[0039] Specifically, by activating the first motor 13 inside the first housing 12, the first rotating shaft 14 and the rotating disk 15 are rotated together, thereby rotating several sets of support plates 16 until the sampling tube 17 on one set of support plates 16 is connected to the water guide pipe 19 on the bottom baffle 18. At this time, the first magnetic ring 22 and the second magnetic ring 24 move away from each other due to the repulsion of like charges, and the solenoid valve 21 inside the fixed ring plate 20 is opened, allowing water to enter the interior of the sampling tube 17. After sampling, the solenoid valve 21 is closed. When the position of the lifting shell 6 changes, the rotating disk 15 is rotated again, and sampling continues in the same manner as above. At the same time, the second motor 28 inside the second housing 27 is activated to drive the second rotating shaft 29 to rotate, thereby driving the four sets of bottom scrapers 30 and the four sets of side scrapers 31 to rotate together to scrape away the blockage on the outside of the filter screen shell 26. This allows for the classification, storage, and sampling of water from multiple points without preventing equipment blockage, reducing the workload of staff and significantly improving water sampling efficiency.

[0040] As one embodiment of the present invention, refer to Figure 1 , Figure 7 A mounting slot 32 is fixedly connected to the upper side of the mounting plate 2. A lead motor 33 is fixedly installed at one end of the mounting slot 32. A threaded shaft 34 is fixedly connected to the output end of the lead motor 33. A moving block 35 is provided inside the mounting slot 32. A wire conduit 36 ​​is fixedly connected to the lower end of the moving block 35. A strip-shaped opening 37 is provided through the middle of the upper surface of the mounting plate 2. A first shaft 38 and a second shaft 40 are fixedly connected to the inside of the opening near the upper and lower sides, respectively. Four sets of first shafts 38 and second shafts 40 are respectively fitted on the outer sides of the first shaft 38 and the second shaft 40. The device has one movable tube 39 and four sets of second movable tubes 41. Both sides of the mounting plate 2 are fixedly connected to connecting side plates 42. The bottom outer sides of the two sets of connecting side plates 42 are provided with first fastening bolts 43. Threaded grooves 44 are opened in the middle of both sides of the main body 1. The two sets of first fastening bolts 43 are threaded to the main body 1 through the threaded grooves 44. The moving block 35 is threaded to the threaded shaft 34. The guide tube 36 is L-shaped. The lifting rope 5 passes through the guide tube 36 and rolls in contact with the first movable tube 39 and the second movable tube 41.

[0041] Specifically, by starting the lead motor 33 at one end of the mounting slot 32, the threaded shaft 34 is rotated. This causes the moving block 35 to slide inside the mounting slot 32 through the threaded connection between the threaded shaft 34 and the moving block 35. The lifting rope 5 is then neatly arranged on the outside of the winding rod 4 through the guide tube 36 and the strip opening 37, preventing the lifting rope 5 from getting stuck in the equipment. At the same time, the first shaft 38 and the second shaft 40 ensure that the first movable tube 39 and the second movable tube 41 are in rolling contact with the lifting rope 5, which can prevent the lifting rope 5 from being damaged by friction with the equipment during winding and unwinding, thus improving the service life of the lifting rope 5.

[0042] Working principle: First, the operator inserts four sets of second fastening bolts 47 through the connecting rings 8 and threaded holes 48 to connect them to the main body 1. At this time, the four sets of connecting blocks 45 are located inside the four sets of connecting grooves 46. Then, the first fastening bolts 43 and threaded grooves 44 are used to engage the two sets of connecting side plates 42 at the middle positions on both sides of the main body 1. Next, the internal threaded ring plate 49 is threaded to the outside of the lifting shell 6, and the filter screen shell 26 is secured to the lower side of the bottom baffle 18 through the external threaded rod 50 and internal threaded tube 51. During use, the rotors 10 on the upper side of the four sets of connecting frame rods 9 allow the main body 1 to move above the water. After the main body 1 reaches the target position, the winding motor 3 at one end of the mounting plate 2 is started. The winding rod 4 is rotated, which in turn lowers the lifting rope 5 and four sets of connecting ropes 7, causing the lifting shell 6 to continuously move away from the main body 1 and sink into the water. This allows for sampling of water at different depths at different positions above the water body, expanding the water sampling range and providing excellent applicability. Next, by starting the lead motor 33 at one end of the mounting tank 32, the threaded shaft 34 is rotated. The threaded connection between the threaded shaft 34 and the moving block 35 causes the moving block 35 to slide inside the mounting tank 32. The guide tube 36, in conjunction with the strip-shaped opening 37, neatly arranges the lifting rope 5 on the outside of the winding rod 4 to prevent it from getting stuck in the equipment. Simultaneously, the first shaft 38 and the second shaft 40... Both the movable tube 39 and the second movable tube 41 are in rolling contact with the lifting rope 5, which can prevent the lifting rope 5 from being damaged by friction with the equipment during the raising and lowering process, thus improving the service life of the lifting rope 5. Finally, by starting the first motor 13 inside the first housing 12, the first rotating shaft 14 and the rotating disk 15 are driven to rotate together, thereby driving several sets of bearing plates 16 to rotate until the sampling tube 17 on one set of bearing plates 16 is connected to the water guide tube 19 on the bottom baffle 18. At this time, the first magnetic ring 22 and the second magnetic ring 24 move away from each other due to the repulsion of like charges, and the solenoid valve 21 inside the fixed ring plate 20 is opened, allowing water to enter the interior of the sampling tube 17. After sampling, the solenoid valve 21 is closed. When the position of the lifting shell 6 is changed... The rotating disk 15 is rotated again. At this time, the second magnetic ring 24 in the sampling tube 17, which has just been sampled, will return to its original position under the cooperation of the limiting rod 23 and the compression spring 25. Then, the sampling continues as described above. At the same time, the second motor 28 inside the second housing 27 is started to drive the second rotating shaft 29 to rotate, thereby driving the four sets of bottom scraper rods 30 and the four sets of side scraper blades 31 to rotate together to scrape off the blockage on the outside of the filter screen 26. This allows for the classification, storage and sampling of water at multiple points without preventing equipment blockage, reducing the workload of staff and significantly improving the efficiency of water sampling. Afterward, the sampling tube 17 with the sample is removed from the support plate 16 by the cooperation of the mounting screw 52 and the mounting screw hole 53, completing the operation.
