Technical Field

[0001] This invention belongs to the field of marine engineering technology and relates to a leveling and vibration-damping base for underwater mooring carriers. Background Technology

[0002] Acoustic buoys are important marine observation devices widely used in underwater topographic mapping, target detection and identification, and marine environmental monitoring. In practical applications, the accuracy of detection and orientation determination of acoustic buoys places extremely high demands on the device's attitude, requiring it to remain horizontal. However, due to the complex and varied seabed topography, the seabed surface is often uneven, causing the buoy to tilt or wobble when seated, severely affecting the accuracy of target orientation detection and data accuracy.

[0003] In existing technologies, acoustic moorings are typically fixed using rigid support structures. This approach cannot effectively adapt to changes in seabed topography and lacks leveling capabilities. Furthermore, existing support structures often neglect vibration reduction performance. Acoustic sensors are sensitive to vibration and are easily affected by seabed vibrations and ocean currents, further impacting detection accuracy and stability.

[0004] Therefore, there is an urgent need for a leveling device that can adjust the attitude of the underwater mooring, adapt to different seabed topographic changes, and has good vibration reduction performance, so as to ensure the stability of the acoustic underwater mooring and the accuracy of target location detection. Summary of the Invention

[0005] The purpose of this invention is to provide a leveling and vibration-damping base for underwater gliders, solving the problems of tilting and vibration when acoustic underwater gliders are placed on uneven seabeds. This device can correct the attitude of the equipment according to different seabed topography and absorb vibration energy through dampers or spring-damped composite structures, reducing vibration interference transmitted from the seabed to the equipment, thereby improving the accuracy of target location detection.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A leveling and vibration-damping base for a submersible mooring carrier, comprising: an outer cover for the mooring mooring; a connecting layer disposed at the bottom of the outer cover; a vibration-damping layer disposed at the bottom of the connecting layer; a leveling layer disposed at the bottom of the vibration-damping layer; an anchoring layer disposed at the bottom of the leveling layer; a plurality of leveling components arranged along the circumferential direction, wherein both ends of each leveling component are movably connected to the leveling layer and the anchoring layer respectively, and an elastic buffer is provided inside the leveling component; and a plurality of anchoring components disposed on the outer circumference of the anchoring layer.

[0007] Preferably, the connecting layer includes a connecting plate, which is detachably connected to the bottom of the submersible outer cover.

[0008] Preferably, the vibration damping layer includes a vibration damping plate, the leveling layer includes a leveling plate, and a vibration damper is provided between the vibration damping plate and the leveling plate.

[0009] Preferably, the anchoring layer includes an anchoring plate, which is fixed to the bottom of the adjusting plate.

[0010] Preferably, the leveling assembly includes a U-shaped seat, the two ends of which are rotatably connected to a first hinge plate and a second hinge plate, respectively, and the elastic buffer is provided between the first hinge plate and the second hinge plate.

[0011] Preferably, the elastic buffer includes a sealing cylinder and a piston rod slidably disposed therein, and a clamping spring is provided between the piston rod and the inner wall of the sealing cylinder.

[0012] Preferably, the end of the piston rod is hinged to the second hinge plate, and the end of the sealing cylinder is hinged to the first hinge plate.

[0013] Preferably, the ends of the first hinge plate and the second hinge plate furthest from the U-shaped seat are respectively hinged to the adjusting plate and the anchoring plate.

[0016] Compared with the prior art, the beneficial effects of the present invention are: In this invention, the underwater glider carrier for marine observation equipment is rigidly connected to the carrier base within the outer casing of the glider via a bottom connecting plate and a connecting plate in the connecting layer. This provides load-bearing capacity to the bottom connection of the acoustic glider and ensures a stable connection between the equipment and the base. The connecting layer is connected by vibration damping plates and dampers in the bottom vibration damping layer. The dampers employ dampers or spring-damped composite structures to absorb vibration energy from the seabed, reducing the impact of vibration on the equipment. This leveling and vibration-damping base, through hierarchical integration, adaptive leveling, dual vibration damping, active anchoring, and modular connection, achieves stable deployment, long-term reliable residence, and safe retrieval of the underwater glider carrier within a limited space. It effectively solves technical problems such as incorrect attitude, susceptibility to impact, and unstable anchoring of underwater gliders in complex seabed terrain, improving the overall reliability and data quality of the underwater glider system.

Detailed Implementation

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. The described embodiments are only some embodiments of the present invention, and not all embodiments.

[0019] This embodiment provides a leveling and vibration-damping base for a submersible buoy carrier, such as... Figures 1-8 As shown, it includes the outer casing 100 of the buoy, and also includes: A connecting layer 200 is installed at the bottom of the outer cover 100 of the buoy, and the connecting layer 200 is used to connect the outer cover 100 of the buoy and the top buoy carrier. Vibration damping layer 300 is installed at the bottom of connecting layer 200. Vibration damping layer 300 is used to buffer and damp the connecting layer 200 and the underwater buoy carrier at the top of the connecting layer 200. The leveling layer 400 is installed at the bottom of the vibration damping layer 300. The vibration damping layer 300 is used for automatic leveling of the connecting layer 200 and the underwater buoy carrier on top of the connecting layer 200. Anchoring layer 500 is installed at the bottom of leveling layer 400. Anchoring layer 500 is used to anchor connecting layer 200 and the underwater buoy carrier at the top of connecting layer 200. Leveling components 600 are installed at equal intervals on the outer circumference of leveling layer 400 and anchoring layer 500; Anchoring components 700 are installed at equal intervals on the outer circumference of leveling layer 400 and anchoring layer 500; The streamlined outer cover 800 is integrally formed at the bottom of the mooring outer cover 100. The streamlined outer cover 800 can reduce the vibration of the mooring outer cover 100 as a whole caused by the fluid. Furthermore, when the mooring carrier is installed in the deep ocean, its external streamlined structure can prevent fishing nets from dragging it.

[0020] The submersible cover 100 includes a carrier base 11 for supporting the submersible carrier. The bottom of the carrier base 11 has a bottom connecting plate 12 integrally formed in a crisscross pattern. The connecting layer 200 includes a connecting plate 21 at the bottom of the bottom connecting plate 12. The connecting plate 21 and the bottom connecting plate 12 are detachably assembled by bolts. The marine observation equipment submersible carrier is rigidly connected to the carrier base 11 in the submersible cover 100, the bottom connecting plate 12, and the connecting plate 21 in the connecting layer 200. This provides load-bearing capacity for the bottom connection of the acoustic submersible and ensures a stable connection between the equipment and the base.

[0021] The vibration damping layer 300 includes a vibration damping plate 31 installed between the connecting layer 200 and the leveling layer 400. The leveling layer 400 includes a leveling plate 41 installed between the anchoring layer 500 and the leveling layer 400. A vibration damper 32 is fixedly installed between the top of the leveling plate 41 and the bottom of the vibration damping plate 31. The connecting layer 200 is connected through the vibration damping plate 31 and the vibration damper 32 in the bottom vibration damping layer 300. The vibration damper 32 adopts a damper or a spring-damping composite structure to absorb vibration energy from the seabed and reduce the impact of vibration on the equipment.

[0022] Anchoring layer 500 includes anchoring plate 51 fixedly installed at the bottom of adjusting plate 41. Adjusting plate 41 has evenly spaced clearance grooves 42 on its outer circumference. Leveling component 600 includes U-shaped seat 61. A first hinge plate 62 and a second hinge plate 63 are movably installed at both ends of the U-shaped seat 61. An elastic buffer 64 is provided between the upper and lower adjacent surfaces of the first hinge plate 62 and the corresponding second hinge plate 63. The elastic buffer 64 includes a sealing cylinder 641. A piston rod 642 is slidably connected inside the sealing cylinder 641. A clamping spring 643 is fixedly installed between the piston end of the piston rod 642 and the inner wall of the sealing cylinder 641. The end of the sealing cylinder 641 away from the sealing cylinder 641 is hinged to the top hinge seat of the second hinge plate 63, and the end of the sealing cylinder 641 away from the piston rod 642 is hinged to the bottom hinge seat of the corresponding first hinge plate 62. When there is a height difference on one side of the outer side of the adjusting plate 41, the higher second hinge plate 63 will push the piston rod 642 inside the sealing cylinder 641 upward, causing the internal pressing spring 643 to be compressed. In this way, the first hinge plate 62 and the second hinge plate 63 can be adjusted in height through the elastic buffer 64 on the adjacent surfaces, so as to achieve adaptive adjustment under different terrain conditions and ensure that the adjusting plate 41 always remains horizontal.

[0023] Angle seats 621 are fixedly installed at equal intervals on the outer circumference of the leveling plate 41. The ends of the first hinge plate 62 and the second hinge plate 63 away from the U-shaped seat 61 are respectively hinged to the interior of the corresponding angle seats 621. Ball cages 622 are fixedly installed on the ends of the first hinge plate 62 and the second hinge plate 63 near the U-shaped seat 61. Connecting columns 611 are detachably installed on the top and bottom ends of the U-shaped seat 61. Ball heads 612 are fixedly installed on the ends of the two sets of corresponding connecting columns 611. The ball heads 612 are omnidirectionally rolled inside the corresponding ball cages 622. Through the omnidirectional rolling cooperation between the ball heads 612 and the ball cages 622, the leveling component 600 can flexibly cope with angle changes in various directions, further enhancing the leveling capability of the device. At the same time, the design of the elastic buffer 64 not only provides stable support but also absorbs external impacts to a certain extent, preventing the equipment from becoming unstable due to sudden external forces.

[0024] Anchoring assembly 700 includes a third hinge plate 71 circumferentially and equally spaced outside the anchoring plate 51. One end of the third hinge plate 71 is hinged to a circumferential hinge seat outside the anchoring plate 51, and the other end of the third hinge plate 71 is fixedly mounted with an anchor claw 72. Electric cylinders 73 are equally spaced and hinged on the bottom circumference of the leveling plate 41. The telescopic ends of the electric cylinders 73 are hinged to the corresponding side of the third hinge plate 71. A distance sensor 631 is mounted on the top of the second hinge plate 63. Each set of distance sensors 631 and the corresponding electric cylinder 73 are electrically connected to a controller. When the second hinge plate 63 in each set of leveling assemblies 600 is flipped upward at a certain angle... After leveling, the corresponding distance sensor 631 can control the adjacent electric cylinder 73 through the controller, so that the electric cylinder 73 in the anchoring assembly 700 drives the corresponding third hinge plate 71 to rotate synchronously, so that the anchor claw 72 can be embedded deeper into the leveled bottom surface. This ensures the stability of the underwater buoy carrier in complex seabed topography. Through the precise control of the electric cylinder 73, the anchor claw 72 can adjust the embedding angle and depth according to the attitude of the leveling layer 400, thereby enhancing the anchoring effect. This linkage mechanism not only improves the adaptability of the base, but also effectively reduces the risk of equipment displacement caused by uneven seabed or external interference.

[0025] In a preferred embodiment of the present invention, the carrier base 11 in the outer casing 100 of the underwater buoy of the marine observation equipment is rigidly connected to the bottom connecting plate 12 and the connecting plate 21 in the connecting layer 200 by flanges and bolts. This provides load-bearing capacity for the bottom connection of the acoustic underwater buoy and ensures a stable connection between the equipment and the base. The connecting layer 200 is connected by the damping plate 31 and the vibration damper 32 in the bottom damping layer 300. The vibration damper 32 adopts a damper or spring-damping composite structure to absorb the vibration energy from the seabed and reduce the impact of vibration on the equipment.

[0026] In this embodiment, after the acoustic mooring carrier is assembled by the mooring outer cover 100, the connecting layer 200 and the vibration damping layer 300 are leveled by the bottom leveling layer 400. The leveling plate 41 is elastically supported by the elastic buffer 64 between the first hinge plate 62 and the second hinge plate 63. Specifically, when there is a height difference on one side of the outside of the leveling plate 41, the higher second hinge plate 63 will push the piston rod 642 inside the sealing cylinder 641 upward, causing the internal pressing spring 643 to be compressed. This allows the first hinge plate 62 and the second hinge plate 63 to adjust their height adaptively through the elastic buffer 64 on adjacent surfaces, achieving adaptive adjustment under different terrain conditions and ensuring that the leveling plate 41 always remains horizontal. Through the omnidirectional rolling cooperation between the ball head 612 and the ball cage 622, the leveling component 600 can flexibly cope with angle changes in various directions, further enhancing the leveling capability of the device. At the same time, the design of the elastic buffer 64 not only provides stable support but also absorbs external impacts to a certain extent, preventing the equipment from becoming unstable due to sudden external forces.

[0027] When the second hinge plate 63 in each leveling assembly 600 is flipped upwards at a certain angle for leveling, the corresponding distance sensor 631 can control the adjacent electric cylinder 73 via the controller. This causes the electric cylinder 73 in the anchoring assembly 700 to drive the corresponding third hinge plate 71 to rotate synchronously, allowing the anchor claw 72 to embed deeper into the leveled bottom surface. This ensures the stability of the mooring carrier in complex seabed terrain. Through the precise control of the electric cylinder 73, the anchor claw 72 can adjust its embedding angle and depth according to the attitude of the leveling layer 400, thereby enhancing the anchoring effect. This linkage mechanism not only improves the adaptability of the base but also effectively reduces... The risk of equipment displacement caused by uneven seabed or external interference is reduced. In addition, when the leveling component 600 on one side detects a change in height, the system will respond quickly and drive the corresponding anchoring component 700 to perform a compensation action to ensure the balance and stability of the overall structure. This design makes full use of the cooperation between the leveling layer 400 and the anchoring layer 500, and shows excellent performance in complex environments. Whether facing a sloping seabed surface or being impacted by ocean currents, the device can maintain a horizontal state through adaptive adjustment. At the same time, relying on the additional gripping force provided by the anchor claw 72, a stable working platform is created for the acoustic detection equipment.

[0028] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes and modifications can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
