Description

Technical Field

[0001] This invention belongs to the field of ship berthing, and in particular to a three-dimensional berthing buffer mooring device driven by hydraulic servo under high sea states. Background Technology

[0002] In typical ports and wharves, breakwaters provide shelter and protection, and the harbor basins are unaffected by waves and currents. Ship berthing and mooring can be achieved using conventional cable systems, anti-collision balls, and simple buffer facilities with unidirectional pull and cushioning. However, in large-scale amphibious landing operations, ports and wharves are often destroyed by the enemy. Large civilian vessels transporting equipment and supplies must berth and transfer to unloading platforms at a certain distance from the landing shore, or in unprotected waters at the minimum suitable depth for the transport vessels. Alternatively, they may construct shore-connecting unloading piers. When berthing and mooring unloading platforms in open, unprotected waters, transport vessels and unloading platforms experience various sea conditions, including wind, waves, and currents. In high sea states, large displacements, including heave, sway, and roll, occur between the transport vessels and the unloading platforms. Firstly, during berthing, unavoidable... The collision could be violent, severely impacting the safety of both the transport vessel and the unloading platform. Secondly, the combined structure formed after the transport vessel berths at the unloading platform experiences intense motion in high sea states, resulting in immense mooring forces between the vessel and the platform. Ordinary cable systems cannot withstand these forces, significantly affecting the safety of weapon and equipment transfer and unloading. Finally, the unloading platform typically has a small freeboard (the unloading platform deck is equivalent to the level of a typical floating dock) and a large height difference with the transport vessel's deck. Given this significant height difference between the transport vessel's high deck and the unloading platform, conventional cable systems cannot meet the safety requirements for weapon and equipment transfer and unloading in high sea states. Summary of the Invention

[0003] The purpose of this invention is to provide a three-dimensional berthing buffer mooring device driven by hydraulic servo under high sea states. It can adhere to any position on the side of a large transport ship at a relatively long distance. Driven by a hydraulic servo system, it can perform large displacement buffering and adaptive large mooring force mooring in three dimensions: heave, sway, and roll. This meets the requirements of large ships berthing at transfer and unloading platforms under unobstructed high sea states with high freeboard, large displacement, large mooring force, and large berthing force buffering, as well as berthing and unloading needs for transshipment.

[0004] The technical solution for achieving the purpose of this invention is as follows: a hydraulically servo-driven three-dimensional berthing buffer mooring device for high sea states, comprising a mounting base, a sway support, an energy storage buffer device, a heave-sway strut, a heave-sway cylinder, and an adaptive matrix suction cup; the mounting base is installed on the deck of the berthing side of the berthing and unloading platform, serving as an installation interface for connecting the berthing and unloading platform; the sway support is hinged to the mounting base to resist large displacements caused by swaying and to resist horizontal torsion of the sway support due to swaying and pitching; the energy storage buffer device is hinged at one end to the sway support and at the other end to the mounting base to absorb the berthing energy of the ship. It provides high-thrust sway buffer, drives the sway support, and controls the berthing distance; the heave and pitch strut, one end of which is hinged to the sway support and the other end of which is hinged to the adaptive matrix suction cup; it is used to transfer the ship's berthing force to the sway support and simultaneously resist the large displacement buffer and mooring caused by heave and pitch; the heave and pitch cylinder is hinged at one end to the heave and pitch strut and the other end to the mounting base; it is used to drive the heave and pitch strut; the adaptive matrix suction cup is used to bear the berthing pressure and transfer the berthing pressure to the heave and pitch strut; wherein, the adaptive matrix suction cup includes a central suction cup, multiple matrix auxiliary suction cups, and corresponding suction cup control cylinders.

[0005] Furthermore, the energy storage buffer device includes a hydraulically servo-driven high-flow-rate, high-thrust cylinder and a hydraulic energy storage buffer. The hydraulic energy storage buffer is mounted on the high-flow-rate, high-thrust cylinder, and both ends of the high-flow-rate, high-thrust cylinder are respectively hinged to the mounting base and the sway support.

[0006] Furthermore, the central suction cup in the adaptive matrix suction cup is hinged to the end of the heave-sway strut; the matrix auxiliary suction cup is arranged around the central suction cup, and the central suction cup is hinged to the end of the heave-sway strut via a universal joint; one end of the suction cup control cylinder is hinged to the heave-sway strut, and the other end is connected to the matrix auxiliary suction cup.

[0007] Furthermore, matrix-type auxiliary suction cups are evenly distributed around the central suction cup and are connected to one end of the auxiliary suction cup control strut via the auxiliary suction cup limiting ball joint 621. The other end of the auxiliary suction cup control strut is connected to the central suction cup base via the auxiliary suction cup strut limiting hinge. Multiple matrix-type auxiliary suction cups are driven by suction cup control cylinders.

[0008] Furthermore, the auxiliary suction cup restricts the ball joint, which includes a ball head seat and a ball joint seat, with a ball joint gap between the ball head seat and the ball joint seat.

[0009] Furthermore, the auxiliary suction cup strut limiting hinge is a single-ear or double-ear hinge, with an upper limit gap and a lower limit gap set between the single and double ears to control the up and down movement stroke of the matrix auxiliary suction cup under the drive of the suction cup control cylinder, so that multiple matrix auxiliary suction cups around the central suction cup can work together to adapt to changes in the side plate profile of the berthing vessel.

[0010] Furthermore, each central suction cup is surrounded by four matrix-style auxiliary suction cups.

[0011] Furthermore, multiple sets of three-dimensional mooring buffer mooring devices are installed for specific use.

[0012] The significant advantages of this invention compared to existing technologies are:

[0013] (1) By combining the large flow and large thrust hydraulic cylinder driven by hydraulic servo with the hydraulic energy storage buffer device, it can absorb the huge energy generated by the large displacement movement between the transport ship and the unloading platform under high sea state, avoid violent collisions during the docking process, and thus ensure the docking safety of the transport ship and the unloading platform under high sea state.

[0014] (2) The hydraulic energy storage buffer device, together with the hydraulic servo-driven high-flow, high-thrust heave and sway cylinder arranged in a specific shape, as well as the heave and sway struts and the trapezoidal frame sway support, can achieve adaptive large mooring force mooring under high sea state and effectively control the relative movement between the transport vessel and the unloading platform, making it possible to unload weapons and equipment by transshipment under high sea state.

[0015] (3) Multiple matrix-type auxiliary suction cups combined with suction cup limiting ball joints can work together to adapt to changes in the side plate profile of the berthing vessel, enabling adsorption and fixation at any position on the side of the vessel, and reducing the mooring safety risk caused by the failure of individual adsorption units, thereby solving the mooring problem of large mooring force between high-deck large transport vessels and unloading platforms in high sea states.

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0020] The hydraulic servo-driven high sea state three-dimensional berthing buffer mooring device includes a mounting base 1, a sway support 2, an energy storage buffer device 3, a heave and sway strut 4, a heave and sway cylinder 5, and an adaptive matrix suction cup 6.

[0021] Mounting base 1 is a frame structure and serves as the installation interface between the berthing buffer mooring device and the berthing unloading platform. It is generally installed on the deck on the berthing side of the berthing unloading platform. Multiple sets can be installed within the range that does not affect the connection of the gangway of the unloading vessel, and are not limited by the original mooring device and winch, thus providing convenience for the berthing of the unloading vessel.

[0022] The sway support 2 is a trapezoidal frame structure. The two bottom corners are hinged to the mounting base 1. Under the support of the energy storage buffer device 3, the sway support 2 can resist the large displacement and mooring caused by swaying, as well as the horizontal torsion of the sway support 2 caused by swaying and rolling. The upper part of the sway support 2 is connected to the heave and sway strut 4, and the middle and upper part is connected to the energy storage buffer device 3.

[0023] The energy storage buffer device 3 includes a hydraulically servo-driven high-flow-rate, high-thrust cylinder 31 and a hydraulic energy storage buffer 32. The hydraulic energy storage buffer 32 is mounted on the high-flow-rate, high-thrust cylinder 31. The lower part of the high-flow-rate, high-thrust cylinder 31 is hinged to the mounting base 1, and the upper part is hinged to the upper middle part of the sway support 2. The energy storage buffer device 3 is mainly used to absorb the berthing energy of the ship, provide high-thrust sway buffer, drive the sway support 2, control the berthing distance, realize lateral adaptive mooring, and ensure a safe distance between the transshipment platform and the unloading ship according to the unloading requirements.

[0024] One end of the heave-sway strut 4 is connected to the sway support 2 via a universal joint, and the other end is hinged to the adaptive matrix suction cup 6 via a universal joint. A pair of heave-sway cylinders 5 are also connected to the end of the adaptive matrix suction cup 6. The main function of the heave-sway strut 4 is to transfer the ship's berthing force to the sway support 2 and simultaneously resist large displacements caused by heave and sway, providing buffering and mooring.

[0025] The heave-sway cylinders 5 are a pair of large-flow, high-thrust cylinders arranged in a V-shape and driven by a hydraulic servo. Their lower parts are horizontally hinged to the outer front of the connection point of the sway support 2 on the mounting base 1 to avoid interference with the sway support 2. The heave-sway cylinders 5 are connected to the outer side of the heave-sway strut 4 by a horizontally rotatable hinge support. The heave-sway cylinders 5 are mainly used to drive the heave-sway strut 4, achieving large displacement buffering caused by heave and sway, providing large mooring forces in the heave and sway directions, and simultaneously working with the energy storage buffer device 3 to resist large displacement buffering caused by sway and provide mooring forces in the sway direction.

[0026] The adaptive matrix suction cup 6 includes a central suction cup 61, a matrix auxiliary suction cup 62, and a corresponding suction cup control cylinder 63.

[0027] The central suction cup 61 is connected to the end of the heave and sway strut 4 via a universal joint 64, which can adapt to the changes in the hull line of the berthing vessel. The central suction cup 61 is the main suction cup, and is equipped with an electrically driven electromagnetic coil and electromagnet inside. It is mainly used to bear the berthing pressure and transmit the berthing pressure to the heave and sway strut 4.

[0028] One end of the suction cup control cylinder 63 is connected to the lifting and swaying strut 4 via a planar universal joint 66, and the other end is connected to the matrix auxiliary suction cup 62 via a universal joint 65.

[0029] Multiple matrix-type auxiliary suction cups 62 are arranged around the central suction cup 61. Each matrix-type auxiliary suction cup 62 is connected to one end of the auxiliary suction cup control strut 622 through the auxiliary suction cup limiting ball joint 621. The other end of the auxiliary suction cup control strut 622 is connected to the base of the central suction cup 61 through the auxiliary suction cup strut limiting joint 623. The multiple matrix-type auxiliary suction cups 62 are driven by the suction cup control cylinder 63.

[0030] The auxiliary suction cups 62 and the central suction cup 61 are not fixedly connected, and each auxiliary suction cup 62 can function independently. If one of the auxiliary suction cups 62 or the central suction cup 61 fails, it will not affect the function of the other suction cups.

[0031] The matrix-type auxiliary suction cup 62 is composed of multiple adsorption units 620 arranged in a matrix. Each adsorption unit 620 consists of a set of electrically driven electromagnetic coils and electromagnets. Setting multiple adsorption units 620 can reduce the mooring safety risk caused by the failure of individual adsorption units 620.

[0032] Preferably, four sets of matrix-type auxiliary suction cups 62 are provided;

[0033] The auxiliary suction cup limiting ball joint 621 includes a ball head seat 6211 and a ball joint seat 6212, with a ball joint gap 6213 between the ball head seat 6211 and the ball joint seat 6212, allowing the matrix auxiliary suction cup 62 to rotate within a certain range to adapt to changes in the side plate profile of the berthing vessel. The auxiliary suction cup strut limiting hinge 623 is a single-ear or double-ear hinge, with an upper limit gap 6231 and a lower limit gap 6232 set between the single and double ears to control the up and down stroke of the matrix auxiliary suction cup 62 driven by the suction cup control cylinder 63, so that multiple matrix auxiliary suction cups 62 around the central suction cup 61 can work together to adapt to changes in the side plate profile of the berthing vessel.
