Logic supporting structure and anti-collision device of offshore structure

Abstract

The invention discloses a logistic supporting structure and an anti-collision device for an offshore structure. The logistic supporting structure comprises a bearing part, a fixing part, inclined struts, and a linear spring; the bearing part and the fixing part are arranged in parallel; the inclined struts comprise first inclined struts and second inclined struts, the first inclined struts and thesecond inclined struts are respectively arranged in pairs, one ends of the two first inclined struts are hinged to the two ends of the bearing part correspondingly, the other ends of the two first inclined struts incline in the opposite direction, one ends of the two second inclined struts are hinged to the two ends of the fixing part correspondingly, the other ends of the two second inclined struts incline in the opposite direction, and the other ends of the two second inclined struts are hinged to the other ends of the corresponding first inclined struts; and the linear spring is arranged between the bearing part and the fixing part, and the two ends of the linear spring are hinged to the intersection points of the first inclined struts and the second inclined struts respectively. The supporting structure has high rigidity in the initial state, when the bearing capacity of the supporting structure reaches a certain threshold value, the structural rigidity is reduced, implementationof normal operation can be ensured, and the impact contact force can be reduced under the impact working condition.

Description

technical field [0001] The invention relates to the technical field of marine and ships, in particular to a logical support structure and anti-collision device for offshore structures. Background technique [0002] Marine and marine engineering structures may be subjected to short-term strong loads such as collisions with out-of-control ships. Effective anti-collision has become a major requirement to ensure the safety of marine engineering structures. [0003] In the traditional anti-collision method, the air bag, viscoelastic material (rubber), metal foam, etc. are introduced into the protected structure (such as offshore wind turbine) (such as figure 1 As shown), the above structure can reduce the impact contact force, but its stiffness is very low. Under normal working conditions (such as berthing a ship), this type of low stiffness material (structure) will also produce large deformation, and the metal foam may also undergo plastic failure. , large waves, etc. may also...

[0003] In the traditional anti-collision method, the air bag, viscoelastic material (rubber), metal foam, etc. are introduced into the protected structure (such as offshore wind turbine) (such as figure 1 As shown), the above structure can reduce the impact contact force, but its stiffness is very low. Under normal working conditions (such as berthing a ship), this type of low stiffness material (structure) will also produce large deformation, and the metal foam may also undergo plastic failure. , large waves, etc. may also cause large deformation or even damage to these low-stiffness materials (structures)
