Embodiment

[0027] like figure 1 and figure 2 , a marine anti-collision device combined with FRP and steel plates, including a plurality of basic anti-collision units 2 and connecting pieces used for connecting between the basic anti-collision units 2, and a plurality of basic anti-collision units 2 surround a protected structure 1 Assembled. Connectors can be bolts, nylon rods or FRP pins.

[0028] like image 3 , the basic anti-collision unit 2 is a fan-shaped cylinder, including an FRP shell 3, a corrugated steel plate anti-collision structure 4, an S-shaped steel plate anti-collision structure 5 and a top cover 6. Wherein, the corrugated steel plate anti-collision structure 4 and the S-shaped steel plate anti-collision structure 5 are embedded in the FRP shell.

[0029] The FRP shell 3 is made of FRP material. The interior of the FRP shell 3 is hollowed out into two parts, the outer side and the inner side. The outer side away from the protected structure 1 is used to embed the c...

Abstract

The invention belongs to the field of structure safety protection of marine engineering, in particular relates to an FRP (Fiber Reinforce Plastic) and steel board combined type offshore collision preventing device, and aims at solving the problem of safety protection of an offshore structure. The device is formed by assembling a plurality of basic collision preventing units around the protected structure, wherein each basic collision preventing unit is in a shape of a sector cylinder and comprises an FRP housing, a corrugated steel plate corrosion preventing structure, an S-shaped steel plate collision preventing structure and a propping cover; the corrugated steel plate collision preventing structure and the S-shaped steel plate collision preventing structure are embedded into the FRP housing; the FRP housing is manufactured through FRP material, and the inside of the FRP housing is hollowed out and divided into an outer side and an inner side which do not communicate; the corrugated steel plate collision preventing structure can be embedded into the outer side, and the S-shaped steel plate collision preventing structure can be embedded into the inner side. With the adoption of the device, the problem of safety protection of the offshore structure can be solved; the corrosion resistance is high while the energy absorbing effect is good, so that the later maintenance cost can be decreased, and the offshore structure can be protected for a long term, and as a result, the offshore work and the assembling and replacing can be conveniently carried out.

Description

technical field [0001] The invention belongs to the field of safety protection of marine engineering structures, in particular to a marine anti-collision device combined with FRP and steel plates. Background technique [0002] With the vigorous development of the transportation industry, more and more large bridges across seas and navigable rivers have been built; at the same time, the world's ships have also become larger and faster. For structures built at sea, such as sea-crossing bridges and offshore platforms, the risk of ship collision has become an important factor that threatens the life cycle safety of offshore structures. [0003] The international database of ship collisions with bridges established by the 19th working group of the PIANO executive meeting of the International Association of Navigation has collected 151 major ship collisions with bridges, which mainly occurred in the Nordic countries, Japan, the United States, Germany, the United Kingdom, France, B...
