[0002] Sediments in the ocean are an important component of oceans, rivers, lakes, reservoirs and other water bodies. They can exchange substances with overlying water bodies through various pathways. The migration and transformation of pollutants such as heavy metals and organochlorine in sediments have an important impact on the living environment of aquatic organisms and benthic animals. The "health status" of sediments is undoubtedly related to the health of aquatic ecosystems, and then affects humans themselves through the food chain. Therefore, the collection and monitoring of sediment samples is of great significance.

[0003] The existing long-axis sampling equipment has the following defects: the existing long-axis sampling equipment is often only equipped with a single sampling tube. After sinking for sampling, the sampling tube needs to be taken out after the device is salvaged. However, the equipment is large in size, the release process is complicated, it has high requirements for sea conditions and is very easy to damage the sampling tube. If only a single sampling is performed each time during the sampling operation, the cost is too high, and it is impossible to collect sediments multiple times and at multiple points without recovering the entire equipment. Summary of the Invention

[0004] The purpose of the present invention is to provide a multi-point long-axis sampling device for clustered seabed sediments in order to solve the above problems, so as to solve the problem that the long-axis sampling equipment in the prior art is often only loaded with a single sampling tube.

[0017] The multi-point long-axis sampling equipment for clustered seabed sediments has a positioning magnet fixedly connected to the outside of the sampling barrel. The positioning magnet and the electromagnetic iron frame are magnetically attracted. By starting the first hydraulic rod, the electromagnetic iron plate fixedly connected to the bottom of the first hydraulic rod is extended into the interior of the sampling barrel. By controlling the power supply group, the electromagnetic iron frame coaxial with the guide frame is powered off, causing the electromagnetic iron frame and the positioning magnet to lose magnetism. As the electromagnetic iron plate pushes the magnet fixing plate, the sampling barrel slides along the guide frame to the movable frame fixedly connected to the bottom of the mounting plate, thereby triggering one of the multiple sampling barrels.

[0018] This clustered multi-point long-axis sampling equipment for seabed sediments monitors the sampling process through a monitoring unit.

The operation is convenient.

[0019] This multi-point long-axis sampling equipment for clustered seabed sediments, when the magnet fixing plate pulls the movable rod to rise, due to the spiral groove opened on the outer side of the movable rod and the arc-shaped limit plate fixedly connected to the inner wall of the connecting tube, the movable rod rotates and rises under the restriction of the arc-shaped limit plate, so that the suction plate fixedly connected to the bottom of the movable rod sucks the sampling tube, and the sediment sample on the seabed is extracted by installing a suction tube fixedly connected to the bottom of the bottom frame, thereby completing the sampling of the seabed sediment. When the sampling is completed, the clamping block is released from the magnet fixing plate, and the positioning plate is withdrawn from the interior of the sampling tube, thereby not affecting the subsequent storage of the sampling tube.

[0020] The multi-point long-axis sampling device for clustered seabed sediments pushes the rack to reset the movable frame to the mounting plate and lowers the mounting plate by activating the first hydraulic rod. The electromagnetic plate is pushed to contact the electromagnetic plate with the magnet fixing plate, so that the electromagnetic plate is energized and magnetically adsorbed with the magnet fixing plate. The electromagnetic ring on the movable frame is de-energized to release the fixation of the sampling tube. The sampling tube is pulled by the electromagnetic plate to be reinserted into the electromagnetic frame fixedly connected to the bottom of the rotating disk. The electromagnetic frame is magnetically fixed to the positioning magnet fixed to the outside of the sampling tube, completing one sampling. As the rotating disk rotates, sampling operations are performed on other sampling tubes, so that sampling operations can be performed on multiple points without recovering the entire tube.

[0037] The top of the rotating disk 4 is fixedly connected to a power supply group 49, and the outer sides of multiple sampling tubes 8 are fixedly connected to positioning magnets 9. The positioning magnets 9 are magnetically adsorbed to the electromagnet frame 7. The bottom of the fixed disk 3 is fixedly connected to a first hydraulic rod 20, and the bottom of the first hydraulic rod 20 is fixedly connected to an electromagnet plate 21, which is conducive to the magnetic adsorption of the positioning magnet 9 and the electromagnet frame 7, so that the sampling tube 8 can be fixed inside the electromagnet frame 7. Multiple sampling tubes 8 can be set at the same time to sample multiple points. The collecting mechanism includes a mounting plate 10, which is fixedly connected to the inside of the sampling tube 8. A suction disc 11 is provided inside the sampling tube 8. The top of the suction disc 11 is fixedly connected to the movable rod 12. The movable rod 12 passes through the mounting plate 10 and is in contact with the inner surface of the sampling tube 8.

[0038] Specifically, by installing the mounting frame 2 and the seabed sinking equipment, and lowering the device housing 1 to the designated location, the first motor is started at this time to drive the rotating rod 5 to rotate. When the rotating rod 5 is fixedly connected to the rotating disk 4, the rotating disk 4 is rotated. Since the bottom of the rotating disk 4 is fixedly connected with a plurality of electromagnet frames 7, a plurality of sampling tubes 8 are provided inside the plurality of electromagnet frames 7, one of the sampling tubes 8 is rotated to the upper part of the guide frame 23 and kept coaxial with the guide frame 23, since the outer side of the sampling tube 8 is fixedly connected with The positioning magnet 9 and the electromagnet frame 7 are magnetically attracted to each other. By starting the first hydraulic rod 20, the electromagnet plate 21 fixedly connected to the bottom of the first hydraulic rod 20 is extended into the sampling tube 8. By controlling the power supply group 49, the electromagnet frame 7 coaxial with the guide frame 23 is powered off, so that the magnetism between the electromagnet frame 7 and the positioning magnet 9 is lost. As the electromagnet plate 21 pushes, the sampling tube 8 slides along the guide frame 23 to the movable frame 24 fixedly connected to the bottom of the mounting plate 22, thereby triggering one of the multiple sampling tubes 8.

[0039] When the sampling tube 8 moves to the bottom of the moving frame 24, since the bottom of the moving frame 24 is provided with a through groove, a spiral groove 18 is threadedly connected to the bottom of the sampling tube 8, and a magnet connecting block 16 is fixedly connected to the bottom of the mounting bottom frame 15. Since the magnet connecting block 16 is adapted to the through electromagnet ring 33, the magnet connecting block 16 is inserted into the through electromagnet ring 33, and by controlling the power supply group 49, the through electromagnet ring 33 and the magnet connecting block 16 are magnetically adsorbed to fix the sampling tube 8. At this time, by starting the second motor 28, the output shaft of the second motor 28 drives the transmission gear 27 to rotate. When the transmission gear 27 rotates, it drives the meshing rack 26 to move. Since the rack 26 is fixedly connected to the moving frame 24, the moving frame 24 drives the magnetically adsorbed sampling tube 8 to move, so that it moves to the middle of the mounting plate 22. A second hydraulic rod 31 is fixedly connected to the bottom of the suction plate 11. By starting the second hydraulic rod 31, the second hydraulic rod 31 is lowered and extended to the inside of the sampling tube 8.

[0040] See also Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 、 Figure 10 、 Figure 11 and Figure 12The bottom of the sampling tube 8 is threadedly connected to the mounting bottom frame 15, and the bottom of the mounting bottom frame 15 is fixedly connected to the magnet connecting block 16. The bottom of the sampling tube 8 is fixedly connected to the suction tube 17. The top of the mounting plate 22 is fixedly connected to the guide frame 23. A through groove is opened at the bottom of the movable frame 24, and a through electromagnet ring 33 is fixedly connected inside the through groove. The through electromagnet ring 33 is magnetically attracted to the magnet connecting block 16, which is conducive to the threaded connection of the bottom of the sampling tube 8 with the mounting bottom frame 15. When taking the sample, the mounting bottom frame 15 can be rotated to take out the sample inside the sampling tube 8. The extraction component includes a second hydraulic rod 31, which is fixedly connected to the bottom of the mounting plate 22. The bottom of the second hydraulic rod 31 is rotatably connected to the positioning plate 32. The bottom of the positioning plate 32 is fixedly connected to a fixed mounting plate 34. The bottom of the fixed mounting plate 34 is fixedly connected to side plates 35 on both sides. A screw rod 36 is rotatably connected between the two side plates 35. The extraction component also includes two clamping blocks 37, screw rod 36 The two ends pass through two clamping blocks 37 respectively and are connected to the clamping blocks 37 by a ball nut pair. The outer side of the screw rod 36 is fixedly connected to a worm gear 38, and the outer side of the worm gear 38 is meshed with a worm 39. The bottom of the fixed mounting plate 34 is fixedly connected to a third motor 41, and the output shaft of the third motor 41 is fixedly connected to the worm 39. The outer side of the screw rod 36 is rotatably connected to a positioning plate 40, and the positioning plate 40 is fixedly connected to the fixed mounting plate 34. The outer side of the moving frame 24 is fixedly connected to a rack 26, and the outer side of the rack 26 is meshed with a transmission gear 27. The bottom of the mounting plate 22 is fixedly connected to a second motor 28, and the output shaft of the second motor 28 is fixedly connected to the transmission gear 27. The outer side of the moving frame 24 is slidably connected to a limit plate 30, which is fixedly connected to the bottom of the mounting plate 22, which is conducive to driving the meshing rack 26 through the transmission gear 27 to move the moving frame 24, so that the moving frame 24 drives the sampling tube 8 for sampling to move and reach the sampling operation area.

[0041] Specifically, at this time, the fixed mounting plate 34 fixedly connected to the bottom of the positioning disk 32 is moved to the top of the magnet fixing plate 13, and the third motor 41 is started at this time, so that the output shaft of the third motor 41 drives the worm 39 to rotate. When the worm 39 rotates, the meshing worm gear 38 is driven to rotate, thereby causing the worm gear 38 to drive the fixedly connected screw rod 36 to rotate. The rotation of the screw rod 36 causes the two clamping blocks 37 to move relative to each other, so that the clamping blocks 37 clamp the magnet fixing plate 13 fixedly connected to the top of the movable rod 12. By starting the second hydraulic rod 31, the second hydraulic rod 31 is retracted. Since the sampling tube 8 and the movable frame 24 are magnetically fixed by the electromagnet ring 33, the two clamping blocks 37 pull the fixed mounting plate 34, so that the two clamping blocks 37 clamp the magnet The fixed plate 13 is pulled upward. Since the bottom of the magnet fixing plate 13 is fixedly connected to the movable rod 12, and the connecting tube 14 is rotatably connected to the mounting plate 10, when the magnet fixing plate 13 pulls the movable rod 12 to rise, a spiral groove 18 is provided on the outside of the movable rod 12, and an arc-shaped limit plate 19 is fixedly connected to the inner wall of the connecting tube 14, so that the movable rod 12 is rotated and raised under the restriction of the arc-shaped limit plate 19, so that the suction plate 11 fixedly connected to the bottom of the movable rod 12 sucks the sampling tube 8, and the sediment sample on the seabed is extracted through the suction tube 17 fixedly connected to the bottom of the bottom frame 15, thereby completing the sampling of the seabed sediment. When completed, the clamping block 37 is released from the magnet fixing plate 13, and the positioning plate 32 withdraws from the sampling tube 8 at the same time.

[0042] The transmission gear 27 is reversed to push the rack 26, so that the movable frame 24 is reset to the mounting disk 22 and the mounting disk 22 is lowered by starting the first hydraulic rod 20, pushing the electromagnetic plate 21 so that the electromagnetic plate 21 contacts the magnet fixing plate 13, so that the electromagnetic plate 21 is energized and magnetically adsorbed with the magnet fixing plate 13, and the electromagnetic ring 33 on the movable frame 24 is de-energized, releasing the fixation of the sampling tube 8, and pulling the sampling tube 8 through the electromagnetic plate 21, so that the sampling tube 8 is reinserted into the electromagnetic frame 7 fixedly connected to the bottom of the rotating disk 4, so that the electromagnetic frame 7 is magnetically fixed to the positioning magnet 9 fixedly connected to the outside of the sampling tube 8, completing one of the samplings. As the rotating disk 4 rotates, the sampling operation is performed on other sampling tubes 8, so that the sampling operation can be performed on multiple points without recovering the entire sample.

[0043] Please refer again Figure 1 、 Figure 2 、 Figure 12 and Figure 13A vertical plate 45 is fixedly connected to one side of the mounting side plate 42, and an electric push rod 46 is fixedly connected to the upper and lower parts of the vertical plate 45. One end of the two electric push rods 46 is fixedly connected to a positioning plug-in plate 47. A positioning groove 48 is provided on the top and bottom of the support plate 44, and the positioning plug-in plate 47 is adapted to the positioning groove 48. A card slot is provided on one side of the mounting side plate 42, and a positioning column is fixedly connected to one side of the support plate 44. The card slot is adapted to the positioning column, which is conducive to quick installation and disassembly of the monitoring unit 43 and convenient operation.

[0044] Specifically, the sampling process is monitored by the monitoring unit 43 at the same time. When the monitoring unit 43 needs to be disassembled, the electric push rod 46 is started to push the positioning plug plate 47, so that the positioning plug plate 47 partially slides out of the positioning groove 48 provided on the outside of the support plate 44, thereby releasing the fixation of the support plate 44 and disassembling the monitoring unit 43, which is easy to operate.
