The invention discloses an anti-collision device for a dock. The anti-collision device comprises a
cantilever-type
pedestrian pedal, a plurality of vertical H-shaped steels, buffering strings and a bottom plate, the
cantilever-type
pedestrian pedal is positioned at the top of the whole device and provided with an L-shaped
transverse plane, a bent short edge is fixed on the dock, a long edge is ofa
cantilever structure, the bottom plate is positioned at the bottom of the whole device, the H-shaped steels are equidistantly welded between the cantilever-type
pedestrian pedal and the bottom platealong the length direction, the buffering strings sleeves the outer sides of the H-shaped steels, are not restrained, can freely lift and fall along with change of
water level and are closely fittedwith a dock needing to be protected, a
retaining wall enclosure state is formed in space, the buffering strings comprise
waste tires and light flexible fillers, the
waste tires are sequentially overlaid and fixed from top to bottom, and the inner sides of the
waste tires are filled with light flexible fillers. The device combines strength and variability, so that passengers can greatly conveniently walk between the dock and a passenger ship, the stability of the ship in docking and the comfort of the passengers are effectively ensured.
