Abstract
Description
Technical Field
[0001] This utility model relates to the field of marine engineering equipment technology, and in particular to a marine foundation monopile cage mooring device with a protective device. Background Technology
[0002] In offshore engineering, the monopile cage berthing component is a crucial part of ship berthing. However, existing monopile cage berthing components lack protective devices. When a ship berths directly, the significant impact force generated during berthing, coupled with long-term exposure to waves and tides, makes these components highly susceptible to damage after prolonged use. This not only increases maintenance costs and repair frequency but also potentially compromises the safety of ship berthing, posing a significant safety hazard. Utility Model Content
[0003] To address the shortcomings of existing technologies, this utility model provides a marine foundation monopile cage mooring component with a protective device, which solves the defects of poor buffering effect and easy damage of rubber guards in existing mooring components, and achieves the technical effects of improving buffering performance, extending the service life of rubber guards, and effectively protecting the pile foundation.
[0004] To achieve the above objectives, the present invention adopts the following technical solution: A marine foundation monopile cage mooring device with protective devices includes a pile foundation, two columns, buffer components, and a rubber saddle. The pile foundation is fixedly connected to the mooring base. The columns are hinged to the pile foundation via connecting rods and located on both sides of the pile foundation. The columns and connecting rods are fixedly connected. The rubber saddle is sleeved on the two columns. The two buffer components are respectively installed on the corresponding columns and are used to buffer the force exerted on the rubber saddle by the ship during berthing.
[0005] Furthermore, the buffer component is a buffer pressure cylinder, with one end of the buffer pressure cylinder hinged to the corresponding column and the other end hinged to the mooring base.
[0006] Furthermore, the buffer component includes a connecting block, a hinge shaft, a sliding block, a guide rail groove, and a spring. The connecting blocks are respectively hinged to both ends of the column, the hinge shaft is hinged to the two connecting blocks, the sliding block is hinged to the hinge shaft, the guide rail groove is fixedly installed on the mooring base, the sliding block is slidably connected to the guide rail groove, and the spring is disposed in the guide rail groove and fixedly connected to the guide rail groove and the sliding block respectively. When the ship is berthed, the spring acts on the rubber guard to buffer the force.
[0007] Furthermore, the rubber guard is configured in a V-shape, with the opening of the rubber guard facing the pile foundation.
[0008] Furthermore, the bent end of the rubber guard is cylindrical to increase the durability of the rubber guard.
[0009] Furthermore, the rubber guard is configured in an arc shape on the side facing the pile foundation to match the pile foundation, in order to prevent the rubber guard from cracking.
[0010] Furthermore, the rubber guard is internally reinforced with an elastic steel plate or a fabric layer.
[0011] Furthermore, a hinged sleeve is rotatably connected to the pile foundation, and the connecting rod is rotatably connected to the hinged sleeve.
[0012] Furthermore, a mooring pile is fixedly connected to the top of the pile foundation.
[0013] Furthermore, the mooring bollards are configured in a cross shape.
[0014] Compared with the prior art, the present invention has the following beneficial effects: By incorporating buffer components, the force exerted on the rubber rigging by the ship during berthing can be effectively buffered, reducing the stress load on the rubber rigging and pile foundation. The rubber rigging adopts a V-shaped design, combined with cylindrical folded ends, an arc-shaped inner structure, and an internal composite elastic steel plate or fabric layer, which significantly improves the durability and crack resistance of the rubber rigging. The column is hinged to the pile foundation through connecting rods, and together with the buffering effect of the buffer components, the overall berthing performance is better, better able to adapt to the impact force when the ship berths, extending the overall service life of the berthing components and effectively ensuring the safety of the offshore mooring foundation and the ship.
