Description

Technical Field

[0001] This invention relates to the technical field of seabed gas leakage collection equipment, specifically a seabed gas leakage in-situ collection device. Background Technology

[0002] Currently, reports of seafloor gas leaks have been found in many sea areas worldwide. These leaked gases may originate from long-standing oil and gas systems in the underlying strata, or they may be hydrocarbons (mainly CH4, etc.) released from the decomposition of leaked gases. Measuring the flux and chemical composition of these leaked gases is of great significance for detecting marine oil and gas resources, exploring leaked gases, understanding the greenhouse effect, and monitoring the marine hydrocarbon generation environment. Therefore, specialized collection devices are needed to collect these gases.

[0003] Submarine seepage gases migrate in two ways: bubbly gas and continuous gas (dissolved gas). Existing collection devices typically collect these bubbly gases by placing collection buckets on the seabed. However, because the collection buckets are in a fixed position, it takes a long time to fill them, resulting in poor collection efficiency for bubbly-migrating submarine seepage gases. To address this issue, we provide an in-situ submarine seepage gas collection device to solve the above problems. Summary of the Invention

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. By setting up a vertical positioner and hydraulic cylinder and other parts, the output end of the drive motor drives the collection roller to rotate, thereby winding up the pull rope, which in turn pulls the first rectangular block to move the bubble collection bucket downward through the sliding seat and the swing rod, thereby adjusting the height of the bubble collection bucket. Then, the hydraulic cylinder is activated, and the output end of the hydraulic cylinder drives the U-shaped push block to move through the Z-shaped power rod to drive the rack to move, thereby driving the spur gear to drive the swing rod to rotate through the shaft, thereby adjusting the angle of the bubble collection bucket, thereby expanding the collection range of seabed seepage gas in bubble form, and thus improving the collection efficiency of seabed seepage gas in bubble form.

[0017] 2. By setting up an embracing auxiliary mechanism, when the U-shaped pusher block moves, the second rectangular block drives the pusher wheel to move, thereby pushing the clamping block to drive the first rotating shaft to rotate. When the U-shaped pusher block moves to the maximum position, the two clamping blocks are clamped on the outer wall of the U-shaped frame, thereby improving the stability of the bubble collection bucket's position adjustment and preventing the bubble collection bucket from shaking after the height is adjusted. This allows the bubble collection bucket to stably collect seabed seepage gas in the form of bubbles.

[0018] 3. By setting a correction guide, the first rotating shaft rotates while the rotating push plate drives the rotating push column to rotate. The rotating push column, under the action of the return groove, pushes the return frame through the T-shaped sleeve to move the shrink block. When the correction wheel abuts against the outer wall of the Z-shaped power rod, the T-shaped sleeve continues to move, correcting the position of the Z-shaped power rod. When the shrink block moves and encounters resistance, the T-shaped sleeve continues to move relative to the shrink block. The cooperation of the above multiple parts improves the accuracy of the U-shaped push block movement, so that the clamping block can be stably clamped on the outer wall of the U-shaped frame.

[0019] 4. By setting up support and protection components, the U-shaped frame moves while the U-shaped slide moves the L-shaped power rod, which in turn moves the irregular block towards the sliding seat via the trapezoidal block. The movement of the irregular block moves the connecting rod via the U-shaped power frame, and the rectangular guide block is pushed by the inclined groove to rotate the support block via the swing block. This ensures that the support block always supports the bottom of the swing rod while the swing rod rotates, thereby improving the stability of the bubble collection bucket after the angle is adjusted.

[0020] 5. By setting up a push-alignment auxiliary unit, the trapezoidal block moves while pushing the ball rod downwards under the action of the inclined surface at one end. When the push rod contacts the ball, the position of the connecting shaft is corrected as the push rod continues to move, thus preventing the connecting shaft from tilting due to the gravity of the bubble collection bucket during long-term use, thereby further improving the stability of the bubble collection bucket when adjusting the angle.

[0035] Please see Figures 1-11 In this embodiment of the invention, an in-situ gas collection device for seabed seepage includes a base 1, a U-shaped support 2 fixedly connected to the top of the base 1, a sliding seat 5 provided on the inner side of the U-shaped support 2, a swing rod 4 rotatably connected to the inner side of the sliding seat 5, a bubble collection bucket 3 fixedly connected to one end of the swing rod 4, a vertical adjuster provided at the bottom end of the sliding seat 5 and the inner side of the U-shaped support 2, a hydraulic cylinder 15 fixedly connected to the top of the swing rod 4, and a U-shaped pusher block 16 fixedly connected to the output end of the hydraulic cylinder 15. The bottom end of the U-shaped push block 16 and the outer walls of both sides of the sliding seat 5 are provided with a circumferential auxiliary mechanism. The outer walls of both sides of the U-shaped push block 16 are fixedly connected with a Z-shaped power rod 17. One end of the Z-shaped power rod 17 is fixedly connected with a rack 19. The outer walls of both sides of the swing rod 4 are fixedly connected with a connecting shaft 21. One end of the connecting shaft 21 passes through to the outside of the sliding seat 5 and is rotatably connected to the sliding seat 5. The outer wall of the connecting shaft 21 is fixedly connected with a spur gear 28 that meshes with the rack 19. The bottom end of the swing rod 4 is provided with a support and protection component.

[0036] The vertical positioner includes a rectangular sleeve 7 fixedly connected to the top of the base 1. A first rectangular block 6 is slidably connected inside the rectangular sleeve 7. The top of the first rectangular block 6 is fixedly connected to the sliding seat 5. A traction spring 9 is fixedly connected to the bottom of the first rectangular block 6. The bottom of the traction spring 9 is fixedly connected to the base 1. A guide wheel 10 is rotatably connected to the bottom of the base 1. A drive motor 11 is installed on one outer wall of the U-shaped frame 2. A collecting roller 12 is connected to the output end of the drive motor 11. One end of the collecting roller 12 is rotatably connected to the U-shaped frame 2. A pull-out rope 8 is fixedly connected to the bottom of the first rectangular block 6. The pull-out rope 8 is wound on the outer wall of the collecting roller 12 and adheres to the outer wall of the guide wheel 10.

[0037] In this embodiment: the output end of the drive motor 11 drives the collecting roller 12 to rotate, thereby winding up the pull-out rope 8, which in turn pulls the first rectangular block 6 to move the bubble collecting barrel 3 downward through the sliding seat 5 and the swing rod 4, thereby adjusting the height position of the bubble collecting barrel 3. Then, the hydraulic cylinder 15 is activated, and the output end of the hydraulic cylinder 15 drives the U-shaped push block 16 to move the rack 19 through the Z-shaped power rod 17, thereby driving the spur gear 28 to rotate the swing rod 4 through the connecting shaft 21, thereby adjusting the angle of the bubble collecting barrel 3, thereby expanding the collection range of seabed seepage gas in bubble form, and thus improving the collection efficiency of seabed seepage gas in bubble form.

[0038] Please refer to this carefully. Figure 4 , Figure 6 , Figure 7 , Figure 8 The circumferential auxiliary mechanism includes connecting blocks 43 fixedly connected to the outer walls of both sides of the sliding seat 5. A first rotating shaft 14 is rotatably connected to the bottom end of the connecting blocks 43. One end of the first rotating shaft 14 extends through to the top of the connecting blocks 43. A clamping block 13 is fixedly connected to the outer wall of the first rotating shaft 14 at the top of the connecting blocks 43. A first torsion spring 45 is installed on the outer wall of the first rotating shaft 14. One end of the first torsion spring 45 is installed at the bottom end of the connecting blocks 43. A second rectangular block 35 is fixedly connected to the bottom end of the U-shaped push block 16. A push guide wheel 36 is rotatably connected to the inner side of the second rectangular block 35. The push guide wheel 36 is attached to the outer wall of the clamping block 13. A correction guide is provided on the outer wall of the first rotating shaft 14 above the clamping block 13.

[0039] In this embodiment: when the U-shaped pusher block 16 moves, the second rectangular block 35 drives the pusher wheel 36 to move, thereby pushing the clamping block 13 to drive the first rotating shaft 14 to rotate. When the U-shaped pusher block 16 moves to the maximum position, the two clamping blocks 13 clamp the outer wall of the U-shaped frame 2, thereby improving the stability of the bubble collection bucket 3 in adjusting its position and preventing the bubble collection bucket 3 from shaking after adjusting its height. This allows the bubble collection bucket 3 to stably collect seabed seepage gas in the form of bubbles.

[0040] Please refer to this carefully. Figures 6-9 The correction guide includes a rotary pusher plate 44 fixedly connected to the outer wall of the first rotary shaft 14. The rotary pusher plate 44 is located above the clamping block 13. A rotary pusher column 40 is fixedly connected to the top of the rotary pusher plate 44. A loop frame 41 is provided at the top of the rotary pusher plate 44. A loop groove 42 is opened on the inner side of the loop frame 41. The rotary pusher column 40 is located inside the loop groove 42. A T-shaped sleeve 46 is fixedly connected to one outer wall of the loop frame 41. A retractable sleeve is slidably connected to the inner side of the T-shaped sleeve 46. Block 38, one end of the shrink block 38 is rotatably connected to multiple correction wheels 37, the other end of the shrink block 38 is fixedly connected to a shrink spring 47, one end of the shrink spring 47 is fixedly connected to a T-shaped sleeve 46, the top of the connecting block 43 is fixedly connected to a U-shaped seat 34, the inner side of the U-shaped seat 34 is slidably connected to a spiral slide 39, the bottom end of the spiral slide 39 is fixedly connected to the T-shaped sleeve 46, and the inner side of the U-shaped seat 34 is provided with a guide groove that matches the spiral slide 39.

[0041] In this embodiment: while the first rotating shaft 14 rotates, it drives the rotating push column 40 to rotate through the rotating push plate 44. Thus, the rotating push column 40 pushes the loop frame 41 through the loop groove 42 to move the shrink block 38 through the T-shaped sleeve 46. When the correction wheel 37 abuts against the outer wall of the Z-shaped power rod 17, the T-shaped sleeve 46 continues to move to correct the position of the Z-shaped power rod 17. When the shrink block 38 is resisted, the T-shaped sleeve 46 continues to move relative to the shrink block 38. Through the cooperation of the above multiple parts, the accuracy of the movement of the U-shaped push block 16 is improved, so that the clamping block 13 can be stably clamped on the outer wall of the U-shaped frame 2.

[0042] Please refer to this carefully. Figures 4-7 The supporting protective component is fixedly connected to the L-shaped seat 26 at the bottom of the sliding seat 5. A second rotating shaft 27 is rotatably connected to the inner side of the L-shaped seat 26. A swing block 29 is fixedly connected to the outer wall of the second rotating shaft 27. One end of the swing block 29 is fixedly connected to a support block 30. A second torsion spring 50 is installed on the outer wall of the second rotating shaft 27. One end of the second torsion spring 50 is installed on the outer wall of the L-shaped seat 26. A linkage auxiliary component is provided at the top of the swing block 29 and the top of the loop carriage 39. The linkage auxiliary component includes components fixedly connected to the loop carriage 39. The top of the L-shaped power rod 33 has a trapezoidal block 22 fixedly connected to one end, an irregular block 48 fixedly connected to one end of the trapezoidal block 22, a U-shaped power frame 25 fixedly connected to the bottom end of the irregular block 48, a connecting rod 31 fixedly connected to the inner side of the U-shaped power frame 25, a rectangular guide block 32 fixedly connected to the top of the swing block 29, a groove 51 opened on the inner side of the rectangular guide block 32, and the connecting rod 31 is set inside the groove 51. The top of the sliding seat 5 is located on one side of the trapezoidal block 22 and a push-alignment auxiliary unit is set there.

[0043] In this embodiment: while the loop frame 41 moves, the loop slide 39 drives the L-shaped power rod 33 to move, thereby driving the irregular block 48 to move towards the sliding seat 5 via the trapezoidal block 22. The movement of the irregular block 48 drives the connecting rod 31 to move via the U-shaped power frame 25. Under the action of the inclined groove 51, the rectangular guide block 32 is pushed to rotate via the swing block 29 to drive the support block 30 to rotate. This ensures that while the swing rod 4 rotates, the support block 30 always supports the bottom end of the swing rod 4, thereby improving the stability of the bubble collection bucket 3 after the angle is adjusted.

[0044] Please refer to this carefully. Figure 5 The push-alignment auxiliary unit includes a shaped seat 18 fixedly connected to the top of the sliding seat 5. A push rod 20 is slidably connected inside the shaped seat 18. The bottom end of the push rod 20 extends through to the bottom of the shaped seat 18. A return spring 49 is fixedly connected to the outer wall of the push rod 20. The bottom end of the return spring 49 is fixedly connected to the shaped seat 18. A ball rod 23 is fixedly connected to the top end of the push rod 20. Multiple balls 24 are embedded in the outer wall of the connecting shaft 21. The shaped seat 18 is composed of an L-shaped plate and a cylindrical sleeve. The sleeve is set on the outer wall of the push rod 20. The bottom end of the push rod 20 is set as an arc. One end of the trapezoidal block 22 is set as an inclined surface. The inclined surface fits against the top end of the ball rod 23. The ball rod 23 is spherical.

[0045] In this embodiment: the connecting shaft 21 is rotatably connected to the sliding seat 5 through the bearing. While the trapezoidal block 22 moves, it pushes the ball rod 23 to squeeze the push rod 20 downward under the action of the inclined surface at one end. When the push rod 20 contacts the ball 24, the push rod 20 continues to move and corrects the position of the connecting shaft 21, so as to prevent the connecting shaft 21 from tilting due to the gravity of the bubble collection bucket 3 during long-term use, thereby further improving the stability of the bubble collection bucket 3 when adjusting the angle.

[0046] Working principle: First, after the base 1 is placed on the seabed, the drive motor 11 is started. The output end of the drive motor 11 drives the collection roller 12 to rotate, thereby winding up the pull-out rope 8. This pulls the first rectangular block 6 to move the bubble collection bucket 3 downward through the sliding seat 5 and the swing rod 4, thereby adjusting the height of the bubble collection bucket 3. Then, the hydraulic cylinder 15 is started. The output end of the hydraulic cylinder 15 drives the U-shaped push block 16 to move the rack 19 through the Z-shaped power rod 17, thereby driving the spur gear 28 to rotate through the connecting shaft 21, thereby adjusting the angle of the bubble collection bucket 3. This expands the collection range of seabed seepage gas in bubble form, thereby improving the collection efficiency of seabed seepage gas in bubble form.

[0047] As the U-shaped pusher block 16 moves, the second rectangular block 35 drives the pusher wheel 36 to move, thereby pushing the clamping block 13 to drive the first rotating shaft 14 to rotate. When the U-shaped pusher block 16 moves to the maximum position, the two clamping blocks 13 clamp the outer wall of the U-shaped frame 2, thereby improving the stability of the bubble collection bucket 3 in adjusting its position and preventing the bubble collection bucket 3 from shaking after adjusting its height, so that the bubble collection bucket 3 can stably collect the seabed seepage gas in the form of bubbles.

[0048] While the first rotating shaft 14 rotates, it drives the rotating push column 40 to rotate through the rotating push plate 44. Thus, the rotating push column 40 pushes the return frame 41 through the return groove 42 and drives the shrink block 38 to move through the T-shaped sleeve 46. When the correction wheel 37 abuts against the outer wall of the Z-shaped power rod 17, the T-shaped sleeve 46 continues to move and corrects the position of the Z-shaped power rod 17. When the shrink block 38 is resisted, the T-shaped sleeve 46 continues to move relative to the shrink block 38. Through the cooperation of the above multiple parts, the accuracy of the movement of the U-shaped push block 16 is improved, so that the clamping block 13 can be stably clamped on the outer wall of the U-shaped frame 2.

[0049] While the loop frame 41 moves, the loop slide 39 drives the L-shaped power rod 33 to move, which in turn drives the irregular block 48 to move towards the sliding seat 5 via the trapezoidal block 22. The movement of the irregular block 48 drives the connecting rod 31 to move via the U-shaped power frame 25. Under the action of the inclined groove 51, the rectangular guide block 32 is pushed to rotate via the swing block 29 to drive the support block 30 to rotate. This ensures that while the swing rod 4 rotates, the support block 30 always supports the bottom of the swing rod 4, thereby improving the stability of the bubble collection bucket 3 after the angle is adjusted.

[0050] As the trapezoidal block 22 moves, it pushes the ball rod 23 to squeeze the push rod 20 downwards under the action of the inclined surface at one end. When the push rod 20 contacts the ball 24, the push rod 20 continues to move and corrects the position of the connecting shaft 21, so as to prevent the connecting shaft 21 from tilting due to the gravity of the bubble collection bucket 3 during long-term use, thereby further improving the stability of the bubble collection bucket 3 when adjusting the angle.

[0051] 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.
