Detailed description of the invention
Purpose and technical scheme for making this utility model embodiment are clearer, implement below in conjunction with this utility model
The accompanying drawing of example, is clearly and completely described the technical scheme of this utility model embodiment.Obviously, described embodiment
It is a part of embodiment of the present utility model rather than whole embodiments.Based on described embodiment of the present utility model,
The every other embodiment that those of ordinary skill in the art are obtained on the premise of without creative work, broadly falls into this practicality
Novel protected scope:
As shown in Figure 1-Figure 3, for the self-floating anti-collision device of a kind of composite of utility model, it is set in ocean knot
On the column 1 of structure thing, fluctuate with water level；Anti-collision device is constituted cylindrical ring body by 4 anti-collision unit combinations being connected,
Described anti-collision unit is respectively anti-collision unit 1, anti-collision unit 23, anti-collision unit 34, and anti-collision unit 45 is described crashproof
Cell cross-section is fan annular, and longitudinal section is oval, radially from limit inwardly successively by glass fiber resin 6, ripple type
Sandwich steel plate 7, polyurethane elastomer 8, inner layer steel plate 9 and polyurethane foam 10 multilayer materials contexture, wherein said
Inner layer steel plate 9 formed inner space filled polyurethane foam 10；Glass fiber resin 6 is placed in outside corrugated core steel plate 7
