Description

Technical Field

[0001] This invention relates to the field of hoisting and release devices, specifically a hoisting and release device and method for seabed geophysical observation. Background Technology

[0002] Marine geophysical observation is an important means of ocean observation, encompassing specific geophysical methods such as seismic, geomagnetic, geoelectric, gravity, and geothermal observations. Currently, conventional methods include ship-borne, towed, and seabed self-contained observations. These conventional methods provide effective data for marine scientific research, seabed geological research, and marine geological hazard research. However, with the deepening of human understanding of the Earth beneath the seabed and the development of science and technology, these conventional methods are gradually showing their inadequacy to meet the needs of scientific research. Because the seabed geophysical field is a long-term changing process, and because earthquakes are frequent at the edges of tectonic plates such as mid-ocean ridges and subduction zones, the regional geophysical field undergoes frequent changes. Conventional geophysical observation methods require ships to be on-site for observation, making all-weather real-time observation impossible, let alone real-time observation during seabed seismic activity. Therefore, specialized seabed geophysical observation devices are needed to obtain real-time marine data.

[0003] Existing seabed geophysical observation devices typically involve mounting the observation equipment onto a frame, which is then released to the seabed using specialized hoisting equipment. During the release and unhooking process at the connection between the frame and the hoisting equipment after the frame has sunk to the seabed, the hoisting cables can easily pull on the frame through the hooks. Because the seabed sand is relatively loose and uneven, this can cause the frame to tip over. Therefore, we provide a hoisting and release device and method for seabed geophysical observation to solve the aforementioned problems. Summary of the Invention

[0004] The purpose of this invention is to address the problem that during the release and unhooking process between the frame and the hoisting equipment, the cables used for hoisting equipment can easily pull on the frame through the hooks, causing the frame to tip over on the seabed.

[0014] As a further embodiment of the present invention: the tightening gripping mechanism includes a gripping hook disposed inside the first fixed seat. A rotating shaft is fixedly connected to the outer walls of both sides of the gripping hook. One end of the rotating shaft extends through to the outside of the first fixed seat and is rotatably connected to the first fixed seat. A ring is fixedly connected to one end of the rotating shaft. A torsion spring is installed on the outer wall of the ring. One end of the torsion spring is installed on the outer wall of the first fixed seat. Protective sleeves are fixedly connected to the outer walls of both sides of the first fixed seat. The protective sleeves are disposed outside the ring. A rectangular actuating block is fixedly connected to the outer wall of the gripping hook. A first L-shaped pulling block is fixedly connected to the bottom end of the lifting ring. The inner side of the first L-shaped pulling block is attached to the bottom end of the rectangular actuating block.

[0015] This invention also discloses a hoisting and release method for seabed geophysical observation, which employs the aforementioned hoisting and release device for seabed geophysical observation and includes the following steps:

[0016] S1. First, the lifting equipment cable is connected to the connecting ring via a hook. Then, the lifting ring is inserted into the outer wall of the support leg. When the two second inclined surfaces contact the spherical locking post, the spherical locking post is pushed to move into the support leg by squeezing the third spring through the rectangular guide block. When the lifting ring moves to its maximum position, the spherical locking post is aligned with the insertion hole, so that the third spring is no longer pushed by external force to drive the rectangular guide block to reset the spherical locking post, so that the spherical locking post is inserted into the insertion hole, thereby fixing the support leg to the lifting ring, so that the workers can release the frame to the seabed using the lifting equipment.

[0017] S2. When the frame sinks to the seabed and the lifting ring needs to be released, the hydraulic cylinder is activated. The output end of the hydraulic cylinder drives the rectangular guide rod to move downward through the third L-shaped pulling block, causing the connecting rod and the T-shaped power block to move downward. This gradually reduces the external force on the second spring, thereby causing the two rectangular sliding blocks to reset. Then, through the protrusion, the rectangular guide block pulls the spherical locking post into the support leg. When the output end of the hydraulic cylinder stops running, the spherical locking post is pulled out from the insertion hole, so that the lifting ring is no longer fixed to the support leg, thus realizing the function of releasing the lifting ring from the support leg.

[0018] S3. When the traction block moves downward, it drives the second rack to move downward, thereby driving the spur gear to rotate the shaft. This, in turn, causes the first rack to move upward through the shaped rod and the second L-shaped pulling block. When the reverse thrust ring contacts the bottom of the lifting ring, the reverse thrust ring continues to move upward, pushing the lifting ring out from the outside of the support leg. This prevents the lifting ring from contacting the support leg, allowing the support leg to be completely released to the seabed. At the same time, it prevents the lifting ring from being pulled when released from the support leg, thereby improving the stability of the frame after release.

[0019] S4. When the thrust ring moves upward but has not yet contacted the lifting ring, the first L-shaped pulling block moves the rectangular moving block to rotate the gripping hook towards the frame, so that the gripping hook can be inserted into the seabed sand. By rotating the four gripping hooks towards the frame at the same time, they form a tight grip with the sand, thereby improving the stability when the lifting ring and the support leg detach, avoiding the frame being pulled, and thus improving the stability of the frame after release.

[0020] S5. When the rotating shaft rotates, the large bevel gear drives the small bevel gear to drive the one-way threaded screw to rotate rapidly, thereby driving the second slider to drive the reinforcing cone to deeply insert into the seabed sand through the rectangular power rod. The reinforcing cone has already been inserted into the seabed sand before the thrust ring contacts the lifting ring, thereby further improving the stability of the frame after release.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] 1. By setting up a reverse thrust unhooking device, when the traction block moves downward, it drives the second rack to move downward, thereby driving the spur gear to rotate the shaft. This, in turn, moves the first rack through the shaped rod and the second L-shaped pulling block to drive the reverse thrust ring upward. When the reverse thrust ring contacts the bottom of the lifting ring, as the reverse thrust ring continues to move upward, it pushes the lifting ring out of the support leg, so that the lifting ring no longer contacts the support leg. This allows the support leg to be completely released to the seabed, and at the same time, it prevents the lifting ring from being pulled when it is released from the support leg, thereby improving the stability of the frame after release.

[0023] 2. By setting up a connecting ring and a spherical locking post, the lifting equipment cable is connected to the connecting ring via a hook. Then, the lifting ring is inserted into the outer wall of the support leg. When the two second inclined surfaces contact the spherical locking post, they push the spherical locking post to move into the support leg by squeezing the third spring through the rectangular guide block. When the lifting ring moves to its maximum position, the spherical locking post aligns with the insertion hole, so that the third spring is no longer pushed by external force to drive the rectangular guide block to reset the spherical locking post, allowing the spherical locking post to be inserted into the insertion hole, thereby fixing the support leg and the lifting ring, so that the workers can release the frame to the seabed using the lifting equipment.

[0024] 3. By setting up the cooperation of hydraulic cylinder and rectangular guide rod and other parts, when the frame sinks to the seabed and the lifting ring needs to be released, the hydraulic cylinder is activated. The output end of the hydraulic cylinder drives the rectangular guide rod to move downward through the third L-shaped pulling block, which in turn drives the connecting rod and T-shaped power block to move downward. This gradually reduces the external force on the second spring, thereby driving the two rectangular sliding blocks to reset. Then, through the protrusion, the rectangular guide block pulls the spherical locking post into the support leg. When the output end of the hydraulic cylinder stops running, the spherical locking post is pulled out from the insertion hole, so that the lifting ring is no longer fixed to the support leg. This realizes the function of releasing the lifting ring from the support leg.

[0025] 4. By setting a clamping stabilizing component, when the rotating shaft rotates, the large bevel gear drives the small bevel gear to drive the one-way threaded screw to rotate rapidly, thereby driving the second slider to drive the reinforcing cone to deeply insert into the seabed sand through the rectangular power rod. The reinforcing cone has already inserted into the seabed sand before the thrust ring contacts the lifting ring, thereby further improving the stability of the frame after release.

[0026] 5. By setting up a tightening gripping mechanism, when the thrust ring moves upward and has not yet contacted the lifting ring, the first L-shaped pulling block moves the rectangular pulling block to drive the gripping hooks to rotate towards the frame, so that the gripping hooks can be inserted into the seabed sand. By having all four gripping hooks rotate towards the frame at the same time, they form a tight gripping state with the sand, thereby improving the stability when the lifting ring and the support leg detach, avoiding the frame being pulled, and thus improving the stability of the frame after release.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. The following describes embodiments of the invention based on its overall structure.

[0039] Please see Figures 1-9 In this embodiment of the invention, a hoisting and release device for seabed geophysical observation includes a frame 1. Four support legs 2 are fixedly connected to the inner side of the frame 1. A hoisting ring 6 is provided on the outer wall of each support leg 2. A docking connector is provided between the hoisting ring 6 and the support leg 2. A connecting ring 8 is fixedly connected to the top of the hoisting ring 6. A first fixing seat 4 is fixedly connected to one side of the outer wall of the support leg 2. A tightening and gripping mechanism is provided on the inner side of the first fixing seat 4. A thrust ring 7 is provided on the outer wall of the support leg 2 below the hoisting ring 6. A thrust release member extending into the interior of the support leg 2 is provided at the bottom end of the thrust ring 7.

[0040] The docking connector includes a rectangular guide rod 21 fixedly connected to the inner side of the support leg 2. Two rectangular sliding blocks 11 are slidably connected to the outer wall of the rectangular guide rod 21. The bottom end of the rectangular sliding block 11 is located inside the support leg 2 and is equipped with a power traction component. The docking connector also includes a rectangular guide block 10 slidably connected to the inner side of the rectangular sliding block 11. A third spring 44 is installed on the inner side of the two rectangular guide blocks 10. A spherical snap-fit ​​post 9 is fixedly connected to one end of the rectangular guide block 10. The inner side of the lifting ring 6 is provided with a plug hole 29 that matches the spherical snap-fit ​​post 9. A second inclined surface 30 is provided at the bottom end of the lifting ring 6. A protrusion 48 is fixedly connected to the top of the rectangular guide block 10. The protrusion 48 abuts against the outer wall of the rectangular sliding block 11.

[0041] In this embodiment: the lifting equipment cable is connected to the connecting ring 8 via a hook, and then the lifting ring 6 is inserted into the outer wall of the support leg 2. When the two second inclined surfaces 30 respectively contact the spherical locking post 9, the spherical locking post 9 is pushed to move into the support leg 2 by squeezing the third spring 44 through the rectangular guide block 10. When the lifting ring 6 moves to the maximum position, the spherical locking post 9 is aligned with the insertion hole 29, so that the third spring 44 is no longer pushed by the external force to drive the rectangular guide block 10 to drive the spherical locking post 9 to reset, so that the spherical locking post 9 is inserted into the insertion hole 29, thereby fixing the support leg 2 and the lifting ring 6, so that the staff can release the frame 1 to the seabed through the lifting equipment.

[0042] Please refer to this carefully. Figures 2-7 The power traction assembly includes a second fixed seat 26 fixedly connected to the inner side of the support leg 2. A hydraulic cylinder 27 is mounted on the top of the second fixed seat 26. A traction block 12 is connected to the output end of the hydraulic cylinder 27. A third L-shaped pulling block 20 is fixedly connected to the top of the traction block 12. A third fixed seat 45 is fixedly connected to the outer walls of both sides of the third L-shaped pulling block 20. A connecting rod 15 is rotatably connected to the inner side of the third fixed seat 45. One end of the connecting rod 15 is rotatably connected to a rectangular sliding block 11. A second spring 43 is installed on the inner side of the two rectangular sliding blocks 11. The two ends of the second spring 43 are respectively fixedly connected to a rectangular sliding block 11. The outer walls of both sides of the traction block 12 are fixedly connected to the first rectangular slider 13. The first rectangular slider 13 is slidably connected to the frame 1. The power traction assembly also includes a T-shaped power block 47 fixedly connected to the top of the third L-shaped pulling block 20. The two sides of the T-shaped power block 47 are provided with first inclined surfaces 19. The outer wall of one side of the rectangular sliding block 11 is fixedly connected to a connecting block 17. The inner side of the connecting block 17 is rotatably connected to a guide wheel 18. The guide wheel 18 abuts against the first inclined surface 19.

[0043] In this embodiment: when the frame 1 sinks to the seabed and the lifting ring 6 needs to be released, the hydraulic cylinder 27 is activated. The output end of the hydraulic cylinder 27 drives the rectangular guide rod 21 to move the connecting rod 15 and the T-shaped power block 47 downward through the third L-shaped pulling block 20, so that the external force on the second spring 43 gradually decreases, thereby driving the two rectangular sliding blocks 11 to reset. Then, through the protrusion 48, the rectangular guide block 10 pulls the spherical locking post 9 into the support leg 2. When the output end of the hydraulic cylinder 27 stops running, the spherical locking post 9 is pulled out from the insertion hole 29, so that the lifting ring 6 is no longer fixed to the support leg 2, thereby realizing the function of releasing the lifting ring 6 from the support leg 2.

[0044] Please refer to this carefully. Figures 5-8The reverse-pull unhooking device includes a rotating shaft 41 rotatably connected to the inner side of the support leg 2. A spur gear 40 is fixedly connected to the outer wall of the rotating shaft 41. Second racks 46 are fixedly connected to the outer walls of both sides of the traction block 12, and the second racks 46 mesh with the spur gear 40. A second L-shaped pulling block 14 is slidably connected to the inner side of the support leg 2. A special-shaped rod 32 is fixedly connected to one end of the second L-shaped pulling block 14. A first rack 34 that meshes with the spur gear 40 is fixedly connected to the top end of the special-shaped rod 32. A fixed ring 33 is fixedly connected, and a first spring 28 is fixedly connected to the bottom end of the fixed ring 33. One end of the first spring 28 is fixedly connected to the second fixed seat 26. One end of the second L-shaped pulling block 14 extends through to the outside of the support leg 2 and is fixedly connected to the reverse thrust ring 7. The outer wall of the rotating shaft 41 and the inner side of the support leg 2 are provided with a clamping stabilizing member. The inner side of the support leg 2 is provided with a guide groove that matches the second L-shaped pulling block 14. The first rack 34 moves longitudinally along the guide groove through the second L-shaped pulling block 14.

[0045] In this embodiment: when the traction block 12 moves downward, it drives the second rack 46 to move downward, thereby driving the spur gear 40 to drive the rotating shaft 41 to rotate, which in turn moves the first rack 34 to drive the thrust ring 7 to move upward through the shaped rod 32 and the second L-shaped pulling block 14. When the thrust ring 7 contacts the bottom of the lifting ring 6, the thrust ring 7 continues to move upward and pushes the lifting ring 6 out of the support leg 2, so that the lifting ring 6 no longer contacts the support leg 2. This allows the support leg 2 to be completely released to the seabed, and at the same time, it prevents the lifting ring 6 from being pulled when it is released from the support leg 2, thereby improving the stability of the frame 1 after release.

[0046] Please refer to this carefully. Figure 5 , Figure 8 , Figure 9 The clamping and stabilizing component includes an H-shaped connecting frame 35 fixedly connected to the inner side of the support leg 2. A one-way threaded rod 37 is rotatably connected to the inner side of the H-shaped connecting frame 35. A small bevel gear 42 is fixedly connected to the top of the one-way threaded rod 37. A large bevel gear 39 that meshes with the small bevel gear 42 is fixedly connected to the outer wall of the rotating shaft 41. A rectangular power rod 36 is slidably connected to the inner side of the H-shaped connecting frame 35. A second slider 38 is fixedly connected to one end of the rectangular power rod 36, and the second slider 38 is sleeved on the outer wall of the one-way threaded rod 37. A reinforcing cone 31 is fixedly connected to the other end of the rectangular power rod 36. A rectangular groove matching the rectangular power rod 36 is opened on the inner side of the H-shaped connecting frame 35. A threaded groove matching the one-way threaded rod 37 is opened on the inner side of the second slider 38.

[0047] In this embodiment: when the rotating shaft 41 rotates, the large bevel gear 39 drives the small bevel gear 42 to drive the one-way threaded screw 37 to rotate rapidly, thereby driving the second slider 38 to drive the reinforcing cone 31 to deeply insert into the seabed sand through the rectangular power rod 36. Before the reverse thrust ring 7 contacts the lifting ring 6, the reinforcing cone 31 has already been inserted into the seabed sand, thereby further improving the stability of the frame 1 after release.

[0048] Please refer to this carefully. Figures 1-5 The tightening gripping mechanism includes a gripping hook 3 located inside the first fixed base 4. A rotating shaft 16 is fixedly connected to the outer walls of both sides of the gripping hook 3. One end of the rotating shaft 16 extends through to the outside of the first fixed base 4 and is rotatably connected to the first fixed base 4. A ring 25 is fixedly connected to one end of the rotating shaft 16. A torsion spring 22 is installed on the outer wall of the ring 25. One end of the torsion spring 22 is installed on the outer wall of the first fixed base 4. Protective sleeves 23 are fixedly connected to the outer walls of both sides of the first fixed base 4. The protective sleeves 23 are located outside the ring 25. A rectangular actuating block 24 is fixedly connected to the outer wall of the gripping hook 3. A first L-shaped pulling block 5 is fixedly connected to the bottom end of the lifting ring 6. The inner side of the first L-shaped pulling block 5 is attached to the bottom end of the rectangular actuating block 24.

[0049] In this embodiment: when the thrust ring 7 moves upward and has not yet contacted the lifting ring 6, the first L-shaped pulling block 5 moves the rectangular moving block 24 to drive the gripping hook 3 to rotate towards the frame 1, so that the gripping hook 3 can be inserted into the seabed sand. By rotating the four gripping hooks 3 towards the frame 1 at the same time, they form a tight gripping state with the sand, thereby improving the stability when the lifting ring 6 and the support leg 2 fall off, avoiding the frame 1 being pulled, and thus improving the stability of the frame 1 after release.

[0050] The following describes a method for lifting and releasing equipment used for seabed geophysical observation, based on the aforementioned lifting and releasing device, specifically including the following steps:

[0051] S1. First, connect the lifting equipment cable to the connecting ring 8 via the hook. Then, insert the lifting ring 6 into the outer wall of the support leg 2. When the two second inclined surfaces 30 contact the spherical locking post 9 respectively, push the spherical locking post 9 to move into the support leg 2 by squeezing the third spring 44 through the rectangular guide block 10. When the lifting ring 6 moves to the maximum position, the spherical locking post 9 is aligned with the insertion hole 29, so that the third spring 44 is no longer pushed by the external force to drive the rectangular guide block 10 to reset the spherical locking post 9, so that the spherical locking post 9 is inserted into the insertion hole 29, thereby fixing the support leg 2 and the lifting ring 6, so that the staff can release the frame 1 to the seabed through the lifting equipment.

[0052] S2. When the frame 1 sinks to the seabed and the lifting ring 6 needs to be released, the hydraulic cylinder 27 is activated. The output end of the hydraulic cylinder 27 drives the rectangular guide rod 21 to move the connecting rod 15 and the T-shaped power block 47 downward through the third L-shaped pulling block 20. This causes the external force on the second spring 43 to gradually decrease, thereby driving the two rectangular sliding blocks 11 to reset. Then, through the protrusion 48, the rectangular guide block 10 pulls the spherical locking post 9 into the support leg 2. When the output end of the hydraulic cylinder 27 stops running, the spherical locking post 9 is pulled out from the insertion hole 29, so that the lifting ring 6 is no longer fixed to the support leg 2. This realizes the function of releasing the lifting ring 6 from the support leg 2.

[0053] S3. When the traction block 12 moves downward, it drives the second rack 46 to move downward, thereby driving the spur gear 40 to drive the rotating shaft 41 to rotate. This, in turn, moves the first rack 34 to drive the reverse thrust ring 7 upward through the shaped rod 32 and the second L-shaped pulling block 14. When the reverse thrust ring 7 contacts the bottom of the lifting ring 6, the reverse thrust ring 7 continues to move upward and pushes the lifting ring 6 out of the support leg 2, so that the lifting ring 6 no longer contacts the support leg 2. This allows the support leg 2 to be completely released to the seabed, and at the same time, it prevents the lifting ring 6 from being pulled when it is released from the support leg 2, thereby improving the stability of the frame 1 after release.

[0054] S4. When the thrust ring 7 moves upward and has not yet contacted the lifting ring 6, the first L-shaped pulling block 5 moves the rectangular pulling block 24 to drive the gripping hook 3 to rotate towards the frame 1, so that the gripping hook 3 can be inserted into the seabed sand. By rotating the four gripping hooks 3 towards the frame 1 at the same time, they form a tight gripping state with the sand, thereby improving the stability when the lifting ring 6 and the support leg 2 fall off, avoiding the frame 1 being pulled, and thus improving the stability of the frame 1 after release.

[0055] S5. When the rotating shaft 41 rotates, the large bevel gear 39 drives the small bevel gear 42 to drive the one-way threaded screw 37 to rotate rapidly, thereby driving the second slider 38 to drive the reinforcing cone 31 to deeply insert into the seabed sand through the rectangular power rod 36. Before the reverse thrust ring 7 contacts the lifting ring 6, the reinforcing cone 31 has already been inserted into the seabed sand, thereby further improving the stability of the frame 1 after release.

[0056] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
