Multi-tube box type integrated sampler for deep-sea submersible sediment sampling operations

Abstract

The present invention provides a multi-tube box-type integrated sampler for deep-sea submersible sediment sampling operations, and relates to the field of deep-sea samplers. The multi-tube box-type integrated sampler for deep-sea submersible sediment sampling operations includes a collection frame, a mounting frame fixedly connected to the top of the collection frame, a support frame fixedly connected to the bottom of the collection frame, and two shovels provided inside the collection frame. The multi-tube box-type integrated sampler for deep-sea submersible sediment sampling operations has a pull plate that rises upward. When the pull plate rises upward, a pulling plate is rotatably connected to one end of the pull plate. As one end of the pulling plate rotates with the shovel, the pulling plate pulls one end of the shovel, causing the shovel to rotate around a rotation point with the collection frame, causing the two oppositely arranged shovels to close, thereby causing the shovels to close the bottom of the collection frame, collect sediment, and simultaneously cooperate with an auger to be collected into the collection frame, thereby improving the collection effect.

Description

Technical Field

[0001] The present invention relates to a sampler technology, in particular to a multi-tube box-type integrated sampler used for sediment sampling operations of deep-sea submersibles, belonging to the technical field of deep-sea samplers. Background Art

[0002] The development of the marine economy and military forces holds crucial strategic significance today, and many countries have begun accelerating their research and development efforts to gain an advantage in the competition for marine resources. Research on the acoustic properties of seafloor sediments (primarily referring to sound velocity and attenuation coefficient) has important applications in military marine environmental surveys, marine engineering surveys, seafloor resource exploration and development, and seafloor environmental monitoring. For example, shallow-water acoustic field analysis and sonar range calculations, shallow-sea engineering geological exploration, and the construction of submarine oil platform engineering bases all require data on the acoustic properties of seafloor sediments. Therefore, studying the acoustic properties of seafloor sediments is an indispensable research topic in fields such as the development of the marine economy and military forces.

[0003] Box samplers can only be carried on observation platforms for box sampling. If multi-tube sampling is required, it is necessary to replace it with a multi-tube sampler for re-sampling. Single-station box and multi-tube sampling consumes about twice the ship time of a single sampling, which is extremely disadvantageous for scientific expeditions with tight ship time and sampling work in extreme field environments (such as polar sea ice environments). At the same time, when sampling, when the sample is pulled up after sampling, the sampled sediment is not sealed thoroughly enough, and the sediment is prone to leakage. At the same time, the existing multi-tube sampler equipment is relatively complex, with many parts, and it takes a long time to assemble and disassemble. The sampling tube is not easy to disassemble. Summary of the Invention

A plurality of counterweights 46 are installed on both sides of the collecting frame 1.

[0040] The threaded rod 10 passes through the connecting plate 11 and the top plate 8 in sequence. The connecting plate 11 is threadedly connected to the threaded rod 10. The threaded rod 10 is movably connected to the top plate 8. A slide groove 13 is provided on the outside of the threaded rod 10. The first gear 14 is sleeved on the outside of the threaded rod 10 and is slidably connected to the threaded rod 10. The inner wall of the first gear 14 is fixedly connected to the limit block 15. The limit block 15 is provided inside the slide groove 13 provided on the outside of the threaded rod 10 and is slidably connected to the slide groove 13. By setting the limit block 15 inside the slide groove 13, when the first gear 14 rotates through the limit block 15 drives the threaded rod 10 to rotate, so that the threaded rod 10 moves upward while being threadedly connected to the connecting plate 11, so that the bottom of the threaded rod 10 is fixedly connected to the auger 12 to roll up the sediment, and the top of the top plate 8 is rotatably connected to the connecting rod 17, and the outer side of the connecting rod 17 is fixedly connected to the second gear 16, the second gear 16 is meshed with the limit block 15, and the top of the top plate 8 is fixed with a mounting plate. A motor 18 is provided on the top of the top plate 8, and the motor 18 is fixedly connected to the mounting plate. The output shaft of the motor 18 is fixedly connected to the connecting rod 17.

[0041] Specifically, when the mounting frame 2 is installed by an external device and fixedly connected to the top of the collecting frame 1, when the collecting frame 1 is sunk as a whole to the seabed, the blade 3 and the auger 12 inside the collecting frame 1 are inserted into the sediment by the weight of the collecting frame 1. A top plate 8 is fixedly connected to the top of the collecting frame 1, and a motor 18 is provided on the top of the top plate 8. At this time, by starting the motor 18, the connecting rod 17 fixedly connected to the output shaft of the motor 18 rotates, and a second gear 16 is fixedly connected to the outside of the connecting rod 17. At this time, the second gear 16 rotates to drive the meshing first gear 14 to rotate. The inner wall of the first gear 14 is fixedly connected to a limiting block 15, which is arranged in a slide groove 13 opened on the outer side of the threaded rod 10. Since the threaded rod 10 is threadedly connected to the connecting plate 11 fixedly connected to the inner wall of the collecting frame 1, the first gear 14 rotates to drive the threaded rod 10 to rotate. When the threaded rod 10 rotates through the threaded connection of the connecting plate 11, the threaded rod 10 moves upward. Since the bottom of the threaded rod 10 is fixedly connected to the auger 12, the auger 12 moves upward and rotates, so that the auger 12 draws the sediment on the outside into the collecting frame 1 for rapid collection, thereby improving the collection effect.

[0042] Please refer again Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 13 、 Figure 14 and Figure 15The shovel 3 is rotated around the position connected to the collection frame 1, so that the two shovel blades 3 are rotated, and the closing component also includes a first pulley 24, the first pulley 24 is fixedly connected to the outer side of the screw rod 22, and the outer side of the connecting rod 17 is fixedly connected to the second pulley 25. The first pulley 24 and the second pulley 25 are connected by a belt transmission. A support plate 23 is provided between the screw rods 22 and is rotatably connected to the support plate 23, which is conducive to the rotation of the connecting rod 17, so that the belt transmission between the two second pulleys 25 and the first pulley 24 is used to make the movable plate 21 rise synchronously, thereby closing the scraper 3. A cross plate 49 is provided between the two side plates 7 and the top plate 8, and the two sides of the cross plate 49 are fixedly connected to the side plates 7 and the top plate 8 respectively. A sealing plate 50 is provided on the top of the two cross plates 49, and teeth are provided on the opposite sides of the two sealing plates 50. The two sealing plates 50 are meshed with the second gear 16 through the teeth. The tops of the two side plates 7 are fixedly connected to the sealing plates 50, and the sealing plates 50 are slidably connected to the limit plates 47. A stopper 48 is provided on one side of the sealing plate 50, and the stopper 48 is fixedly connected to the collection frame 1, which is conducive to the second gear 16 driving the meshing sealing plate 50 to move when the scraper 3 is closed, so that the collection frame 1 is quickly closed.

[0043] A first mounting plate 28 is fixedly connected to the outside of the two sampling tubes 4, a second mounting plate 29 is provided on the top of the first mounting plate 28, a plurality of partitions 31 are fixedly connected between the second mounting plate 29 and the first mounting plate 28, and a one-way valve 30 is provided on the top of the sampling tube 4.

[0044] Specifically, when the connecting rod 17 rotates, two second pulleys 25 are fixedly connected to the outside of the connecting rod 17, and the belt transmission between the second pulley 25 and the first pulley 24 causes the screw rod 22 fixedly connected to the outside of the first pulley 24 to rotate. When the screw rod 22 rotates, the movable plate 21 connected to the outside of the screw rod 22 through the ball nut pair, and the pulling plate 20 is fixedly connected to the bottom of the movable plate 21, and the pulling plate 20 passes through the side plate 7 and is slidably connected to the side plate 7, thereby moving the movable plate 21. The limit is set, so that the pulling plate 20 rises upward. When the pulling plate 20 rises upward, a pulling plate 51 is rotatably connected to one end of the pulling plate 20. Since one end of the pulling plate 51 rotates with the shovel 3, the pulling plate 51 pulls one end of the shovel 3, causing the shovel 3 to rotate around the rotation point of the collection frame 1, so that the two oppositely arranged shovels 3 are closed, so that the shovel 3 closes the bottom of the collection frame 1 and collects the sediment. At the same time, it cooperates with the auger 12 to be collected into the collection frame 1, so as to improve the collection effect.

[0045] When the second gear 16 rotates, a sealing plate 50 is provided on the top of the horizontal plate 49. At this time, the sealing plate 50 is engaged with the second gear 16 through the teeth opened on the outside of the sealing plate 50, so that the two sealing plates 50 are limited and moved, so that the sealing plate 50 closes the collecting frame 1, thereby preventing the sediment from floating out of the collecting frame 1 due to shaking when the collecting frame 1 rises, and sealing it through the sealing plate 50.

[0046] Please refer again Figure 1 、 Figure 2 、 Figure 3 、 Figure 8 、 Figure 10 、 Figure 11 and Figure 12 A plurality of baffles 42 are provided at the bottom end of the sampling tube 4, and the plurality of baffles 42 are distributed in a ring inside the sampling tube 4. A cross bar 43 is fixedly connected to one side of the plurality of baffles 42. The plurality of cross bars 43 pass through the sampling tube 4 and are rotatably connected to the sampling tube 4. A rotating plate 44 is fixedly connected to the outer side of the plurality of cross bars 43. A plurality of limiting rods 45 are fixedly connected to the inner wall of the sampling tube 4. The plurality of limiting rods 45 are distributed in a one-to-one correspondence with the plurality of baffles 42 and are respectively arranged below the limiting rods 45. When the sampling tube 4 descends, the baffle 42 is inserted into the sediment. When the sampling tube 4 rises, the limiting rods 45 support the baffle 42, so that the baffle 42 closes the bottom of the sampling tube 4.

[0047] Specifically, when the bottom of the sampling tube 4 is inserted into the sediment, a plurality of baffles 42 are provided at the bottom end of the sampling tube 4, and the baffles 42 are inserted into the sediment. When the collecting frame 1 is pulled up and the sampling tube 4 is raised, the sediment inside will move downward, so that the sediment is pressed on the other side of the baffle 42, so that the baffle 42 rotates around the fixed cross bar 43. The cross bar 43 is rotatably connected to the sampling tube 4, and a rotating plate 44 is fixedly connected to the outside of the cross bar 43. When the sampling tube 4 rises, the rotating plate 44 is rotated by the rotating plate 44, so that the baffle 42 rotates. A limiting rod 45 is fixedly connected to the inner wall of the sampling tube 4, and the bottom of the baffle 42 is supported by the limiting rod 45, so that the baffle 42 cannot be flipped, so that the baffle 42 remains horizontally expanded, the bottom of the sampling tube 4 is closed, and squeezed out through the one-way valve 30 provided on the top of the sampling tube 4.

[0048] Please refer again Figure 1 、 Figure 2 、 Figure 3 、 Figure 8 、 Figure 10 、 Figure 11 and Figure 12 The fixed component includes a gear ring 33, which is rotatably connected to the fixed plate 5. A worm gear 34 is fixedly connected to the top of the gear ring 33. A plurality of third gears 37 are meshed and connected to the outer side of the gear ring 33. The plurality of third gears 37 are all rotatably connected to the fixed plate 5. A vertical rod 38 is fixedly connected to the top of the plurality of third gears 37. The top of the vertical rod 38 is fixedly connected to the fourth gear 39, which is conducive to driving the meshed and connected plurality of third gears 37 to rotate through the gear ring 33 so that they rotate synchronously. The fixed component also includes a rack 40 corresponding to the plurality of fourth gears 39 one by one. Multiple racks 40 are respectively meshed and connected with multiple fourth gears 39, and the fourth gears 39 are distributed in a ring around the worm gear 34. There are connecting blocks 41 on the outside of the multiple racks 40. The racks 40 are slidably connected to the connecting blocks 41, and the connecting blocks 41 are fixedly connected to the fixed plate 5. The outside of the worm gear 34 is meshed and connected with a worm 35. The outside of the worm gear 34 is provided with a vertical plate 36 and is rotatably connected to the vertical plate 36. The vertical plate 36 is fixedly connected to the fixed plate 5. The meshing of the worm 35 and the worm gear 34 has a locking effect, so that the rack 40 is inserted between the multiple partitions 31, thereby fixing the sampling tube 4.

[0049] Specifically, when the collecting frame 1 pulls the ship deck as a whole, the worm 35 is rotated to drive the meshing worm wheel 34 to mesh, so that the gear ring 33 fixedly connected to the bottom of the worm wheel 34 rotates. When the gear ring 33 rotates, it drives the multiple meshing third gears 37 to rotate. The outside of the third gear 37 is fixedly connected to a vertical rod 38. At this time, the top of the vertical rod 38 is fixedly connected to a fourth gear 39. The rotation of the vertical rod 38 drives the meshing rack 40 to move, so that the rack 40 moves out of the gap between the multiple partitions 31 fixedly connected between the first mounting plate 28 and the second mounting plate 29 fixedly connected to the outside of the sampling tube 4. When installing, the transmission is reversed to insert one end of the rack 40 between the multiple partitions 31, so that the sampling tube 4 is quickly installed, which facilitates the installation and disassembly of the sampling tube 4 and facilitates its later placement.
