A flexible hinged structure of a floating body module

Abstract

A flexible hinge structure of a floating body module comprises a first floating body module, a second floating body module and a connector. The connector comprises a first articulated seat and a second articulated seat. A via hole A is arranged on the end plate of the first floating body module, the holding space is arranged in the inner part of the first floating body module, at the back surfaceof end plate, a stop baffle is arranged in the holding space, and a via hole B is arranged on the stop plate; the first seat body is inserted into the holding space from the via hole A to the via holeB, and the first seat body can slide along the longitudinal direction; the first seat body is provided with an oval leaf spring, and the oval plate spring is always positioned between the end plate and the stop plate and does not fall off; the first and second floating body module structures are the same; The first hinge seat and the second hinge seat are identical in other structures and assembly relationship except that the structures of hinge heads are different, and the first seat body and the second seat body are mirror symmetric with respect to the hinge point. The floating body modulehas the advantages that the structure is reliable, the longitudinal rocking motion of the floating body can be released, the load along the longitudinal direction of the floating body can be effectively reduced, and the safe operation of the ultra-large floating body is ensured.

Description

technical field [0001] The invention belongs to the field of marine engineering equipment, and in particular relates to a flexible hinged structure of a floating body module. Background technique [0002] Large-scale floating structure is a new type of equipment in the field of large-scale ocean engineering technology. Large floating structures can be used as offshore deployment platforms, floating airports, floating cities, and more. It is huge, with a length of a kilometer and a displacement of millions of tons. [0003] Large-scale floating structures are generally formed by connecting multiple floating body modules to facilitate manufacturing and installation. Therefore, the connectors between the modules are related to the dynamic characteristics and reliability of the entire floating structure. The common ones are welding, rigid connection, hinge, flexible connector and so on. These types of connectors have their own advantages and disadvantages. If the connection ...

AI Technical Summary

Problems solved by technology

These types of connectors have their own advantages and disadvantages. If the connection is to be reliable, the connector load is too large and the fatigue characteristics of the connector are poor.

For example, some scholars have proposed to use rigid hinged connectors to reduce the connector load by releasing the pitch freedom of the floating body. However, this connection scheme will also generate huge connector loads under special sea conditions, especially along the floating body. The load in the direction is still very large, and it is difficult to meet the strength design requirements of its structure
