Learn superior performance, and retention properties is stable in the seawater, do not fear corrosion, reduce maintenance cost.
The self-floating anti-collision device of the composite that the present invention provides, the corrugated core steel plate of employing, touches
By the plastic deformation of steel when hitting, absorbable a large amount of abilities, there is light unit weight, intensity change high, moulding
The advantages such as shape power consumption is big.Compared to Energy dissipating material such as traditional foamed aluminiums, there is more preferable energy-absorbing effect.
The self-floating anti-collision device of the composite that the present invention provides, the polyurethane elastomer of employing is outstanding
Subtract weakening function and can consume a part of external force load energy, effectively slow down simultaneously corrugated core steel plate and
The tear occurred in inner layer steel plate collision process.
The self-floating anti-collision device of the composite that the present invention provides, uses polyurethane foam as fender
Material, delays the deformation of anti-collision device, absorbs big energy simultaneously.
The self-floating anti-collision device good integrity of the composite that the present invention provides, it is convenient to install, and each is prevented
Hitting unit uses ring flange to carry out assembling and seal, and after Local Damaged, has certain recoverability and replaceable
Property.
The self-floating anti-collision device of the composite that the present invention provides is lightweight, has from buoyancy, can meet
Requirement with water level float.
The self-floating anti-collision device of the composite that the present invention provides, the curved profile of employing can hit
Time push shipping agency direction aside, farthest stopped the probability that boats and ships are nested against one another with anti-collision device, made
The Impact energy of ship retains aboard ship mostly.
Accompanying drawing explanation

Detailed description of the invention
Purpose and technical scheme for making the embodiment of the present invention are clearer, below in conjunction with the embodiment of the present invention
Accompanying drawing, is clearly and completely described the technical scheme of the embodiment of the present invention.Obviously, described reality
Execute a part of embodiment rather than whole embodiments that example is the present invention.Based on the described present invention
Embodiment, the every other reality that those of ordinary skill in the art are obtained on the premise of without creative work
Execute example, broadly fall into the scope of protection of the invention:
As shown in accompanying drawing 1 to Fig. 3, for the self-floating anti-collision device of a kind of composite of the present invention, set
It is loaded on the column 1 of marine structure, fluctuates with water level；Anti-collision device by 4 be connected anti-
Hit unit combination constitute cylindrical ring body, respectively anti-collision unit 1, anti-collision unit 23, anti-collision unit 34,
Anti-collision unit 45, described anti-collision unit cross section is fan annular, and longitudinal section is oval, radially from limit
Inwardly successively by glass fiber resin 6, corrugated core steel plate 7, polyurethane elastomer 8, inner layer steel plate 9
