Vessel side-by-side anti-collision device adapted to multiple sea conditions

Abstract

The embodiment of the invention relates to a vessel side-by-side anti-collision device adapted to multiple sea conditions. The vessel side-by-side anti-collision device adapted to multiple sea conditions comprises an anti-collision air sac module, an air sac binding frame module and an atmospheric pressure stabilizing module, wherein the atmospheric pressure stabilizing module is located in the anti-collision air sac module, and is connected with a control mechanism component; the anti-collision air sac module is located in the air sac binding frame module; and the air sac binding frame moduleis fixed to the broad side of a receiving vessel through wire ropes. According to the vessel side-by-side anti-collision device adapted to multiple sea conditions disclosed by the invention, a combined structure is adopted to jointly bear extruding force generated by side-by-side of two vessels, so that the vessel side-by-side anti-collision device can be adapted to different sea conditions; through increasing or reducing the number of air sacs, the shape and the dimension of the anti-collision air sac module can be changed, so that the vessel side-by-side anti-collision device can be betteradapted to linetype flaring of the vessels, and the side-by-side spacing of the two vessels can be changed; and through the atmospheric pressure stabilizing module, the air tightness problem of the air sacs and the pressure dropping problem of the air sacs caused by the side-by-side extruding force of the two vessels are solved, the situation that when the vessel performs a side-by-side operationunder different sea conditions, the internal atmospheric pressure of the anti-collision air sacs is always kept to be a preset atmospheric pressure value is guaranteed, and the bearing capacity of theanti-collision air sac is guaranteed.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of ships, in particular to a ship and anti-collision device adaptable to various sea conditions. Background technique [0002] When ships are alongside for replenishment, especially under extreme sea conditions, under the combined action of wind, waves and currents, due to the narrow gap between the two ships, hydrodynamic interference will occur between the two ships. A large number of observations show that the hydrodynamic disturbance includes not only the first-order force, which causes the receiving ship and the supply ship to generate a coupled motion disturbance response, but also includes the second-order steady offset force, which causes the average position of the receiving ship and the supply ship to deviate. Due to the hydrodynamic interaction, the violent movement between the receiving ship and the supply ship will lead to the failure of the sea supply, and more serious...

Problems solved by technology

[0004] However, the inflatable rubber fender with built-in safety valve has the following disadvantages: first, the flexible fender is not suitable for extreme sea conditions; second, the size of the flexible fender is fixed, and the distance between two ships cannot be controlled; It is single and cannot adapt to the floating of the hull line. Fourth, due to the airtightness of the fenders and the extrusion force of the two ships, the fenders will have a pressure drop and the bearing capacity will be reduced.
