Description

Technical Field

[0001] The utility model relates to the technical field of ship safety, in particular to a ship berthing buffer device which is adaptable to different berthing distances. Background Art

[0002] On some ships, in order to reduce the damage to the hull and the port caused by collisions during docking and mooring, when planning berthing facilities, consideration is given to installing buffer devices on the ship's side, such as air cushions, rubber rings and other energy-absorbing materials. For example, the prior patent CN217348174U discloses a safety device for ship docking anti-collision - adding a spring to the airbag. However, existing buffer devices can only be applied to ship docking application scenarios with a fixed berthing distance. When the docking application scenario changes (for example, a buffer device designed based on docking is applied to a mooring scenario, and the ship's displacement changes significantly), the buffering energy absorption performance and berthing distance provided by the existing buffer devices will obviously lack applicability. For example, when a buffer device designed based on docking is applied to a mooring scenario, the mooring operation may be dangerous due to excessive rebound force and too short a berthing distance.

[0003] Therefore, the prior art urgently needs a buffer device that can meet the needs of various berthing scenarios. Utility Model Content

[0004] In view of the above problems, the present invention is proposed to provide a ship berthing buffer device that is adaptable to different berthing distances to overcome the above problems or at least partially solve the above problems, thereby improving the navigation safety of ships.

[0005] Specifically, the utility model provides a ship berthing buffer device adapted to different berthing distances, comprising:

[0006] a fixed base configured to be mounted on the side of the vessel;

[0007] a movable base connected to the fixed base via a driving mechanism, wherein the driving mechanism is configured to control a distance between the movable base and the fixed base;

[0008] A buffer washer is provided on a side of the movable base away from the fixed base to facilitate the movable base to move closer to or away from the fixed base under the control of the driving mechanism.

[0009] The fixed base is installed on the side of the ship, and the movable base is driven by the driving mechanism to adjust the distance between it and the fixed base, so that the position of the buffer washer can be adjusted, so that the buffer washer can move closer to or away from the fixed base to meet the needs of various berthing scenarios.

[0010] Optionally, the driving mechanism includes an adjusting rod arranged between the root of the movable base and the fixed base, the adjusting rod passes through the fixed base and slides with the fixed base, and the driving mechanism also includes a driving gear arranged on the rear side of the fixed base, and the driving gear respectively cooperates with the gear rack between the adjusting rod.

[0011] By setting an adjusting rod between the root of the movable base and the fixed base, and setting a driving gear on the rear side of the movable base, and the gear rack between the driving gear and the adjusting rod cooperate, the driving gear is rotated to drive the adjusting rod to adjust its position in the fixed base, so as to adjust the distance between the buffer gasket on the front side of the movable base and the hull, so as to meet the needs of various berthing scenarios.

[0012] Optionally, a driving base is provided at the rear end of the fixed base, a driving motor is provided on the driving base, the driving gear is rotatably connected in the driving base, and the driving motor drives the driving gear to rotate to adjust the position of the adjusting rod on the fixed base.

[0013] The driving base can support the driving gear, and the driving motor drives the driving gear to rotate, thereby driving the adjusting rod to adjust its position on the fixed base.

[0014] Optionally, the buffer washers are provided in multiple groups, and a washer base is provided between the multiple groups of buffer washers and the movable base, and the multiple groups of buffer washers are provided on the washer base.

[0015] By setting up multiple groups of buffer washers, it can be avoided that when the ship is docking, a single buffer washer falls off due to the friction between the ship and the dock and can no longer provide protection for the ship. On the other hand, multiple groups of buffer washers can disperse the force on each buffer washer and extend the service life of the buffer washers.

[0016] Optionally, a telescopic rod is provided between the root of the washer base and the movable base, a buffer spring is sleeved on the telescopic rod, and the roots of the telescopic rod and the buffer spring are both embedded in the movable base, and a buffer cavity is provided inside the movable base.

[0017] By setting up a telescopic rod in conjunction with a buffer spring, it can play a buffering role when the washer base is under pressure, thereby assisting in protecting the use of the buffer washer. The roots of the telescopic rod and the buffer spring are embedded in the movable base in order to improve the matching stability between the telescopic rod and the buffer spring, as well as the buffering stability of the washer base.

[0018] Optionally, the telescopic rods are symmetrically arranged in multiple groups between the root of the washer base and the movable base, and a hydraulic buffer rod is arranged in the middle position between the root of the washer base and the movable base. The maximum compression stroke of the hydraulic buffer rod is greater than the maximum telescopic stroke of the telescopic rod. When the washer base is pressurized, the hydraulic buffer rod cooperates with the buffer spring to assist in reducing the impact force of the washer base on the movable base, and the telescopic rod can avoid damage caused by excessive compression of the hydraulic buffer rod.

[0019] When the washer base end is under pressure, the hydraulic buffer rod can reduce the impact force of the washer base on the movable base. In order to avoid damage to the hydraulic buffer rod due to pressure, the maximum compression stroke of the hydraulic buffer rod is greater than the maximum telescopic stroke of the telescopic rod. When the washer base is under pressure and produces the maximum compressive displacement, the telescopic rod will be supported between the washer base and the movable base, thereby avoiding damage caused by excessive compression of the hydraulic buffer rod.

[0020] Optionally, a rotating connecting seat is provided at one end of the two sets of mounting plates away from the fixed base.

[0021] By providing a rotating connecting seat, the fixed base can be provided with left and right swinging support when the fixed base is installed on the ship, thereby improving the adaptability of the fixed base during installation.

[0022] In the technical solution of the present invention, an adjusting rod is provided between the root of the movable base and the fixed base, and a driving gear is provided on the rear side of the movable base, and the gear rack between the driving gear and the adjusting rod cooperates. By rotating the driving gear, the adjusting rod is driven to adjust its position in the fixed base, thereby adjusting the buffer gasket on the front side of the movable base and the distance compared to the hull, thereby achieving a buffer device that meets the needs of various berthing scenarios.

[0023] Furthermore, in the technical solution of the present invention, by setting up multiple groups of buffer washers, it is possible to avoid the situation where a single buffer washer falls off due to the friction between the ship and the dock when the ship is docked, and can no longer provide protection for the ship when docking. On the other hand, the multiple groups of buffer washers can disperse the force on each buffer washer and extend the service life of the buffer washers.

[0038] By means of two sets of mounting plates 2 symmetrically arranged on the fixed base 1, the fixed base 1 can be conveniently installed on the side of the ship. An adjusting rod 4 is arranged between the root of the movable base 3 and the fixed base 1, and a driving gear is arranged on the rear side of the movable base 3.

By providing multiple groups of buffer washers 6, it is possible to avoid that when the ship is docked, a single buffer washer 6 falls off due to the friction between the ship and the dock, and can no longer play a protective role in the docking of the ship. On the other hand, the multiple groups of buffer washers 6 can disperse the force on each buffer washer 6 and extend the service life of the buffer washer 6.
