Device for passively slowing relative rotation of ultra-large floating body

Abstract

The invention relates to a device for passively slowing relative rotation of an ultra-large floating body, which comprises a main base and an auxiliary base, wherein the main base is arranged at intervals, and the auxiliary base is provided with holes; the outer side of the auxiliary base is butted with a sliding rod, one end of a guide rod is connected with the inner side of the main base, the other end of the guide rod sequentially runs through the holes and the sliding rod of the auxiliary base, and a slowing device for slowing the rotation is wound on the periphery of the guide rod; a plurality of torsion rods are symmetrically arranged between the main base and the auxiliary base by taking the guide rod as a center, one end of each torsion rod is hinged with the main base, and the other end of each torsion rod is hinged with the auxiliary base. The device for passively slowing relative rotation of the ultra-large floating body has simple structure and convenient use, has higher independence, and can achieve passive constrained motion and provide restoring force through the main base, the auxiliary base, the guide rod and the torsion bar; the torsion bar has stronger damping without manual intervention, and is convenient to install and disassemble on the sea.

Description

technical field [0001] The invention relates to the technical field of marine engineering, in particular to a device for passively slowing relative rotation of a super-large floating body. Background technique [0002] The ocean super-large floating body is composed of multiple modules connected to each other through connectors, which can be connected vertically in series or horizontally in parallel. In the complex ocean environment, the buoyancy changes caused by the movement of super-large floating bodies in waves, which in turn lead to huge wave loads. If the super-large floating body is rigidly connected, once it encounters a wave with a large wavelength, a huge vertical external load will be generated instantaneously; in addition, if it encounters an oblique wave, the lateral external load and torsional load are more likely to occur and increase sharply. In this case, the weakest structure along the length of the ship will be the most vulnerable to damage, and because ...

Problems solved by technology

With the gradual deepening of domestic research on super-large floating bodies at sea, the connection methods and connector structures are becoming more and more extensive. In particular, the application of articulated flexible connectors is more common. However, in the process of use, the super-large floating body modules The relative pitch of the aircraft is completely unconstrained, and this unconstrained situation greatly affects the continuity of its deck and the integrity of the airstrip. Therefore, certain damping should be added to slow down the motion during this relative rotation The amplitude or the corresponding restoration torque can make the module recover to the previous state as soon as possible, but this design is still blank at present.
