The invention relates to a 
beacon for ship navigation and belongs to the technical field of navigation. The 
beacon for the ship navigation comprises a wave 
electric generator, memory supporting rods, an energy accumulator, a concave cover, a support, a support column, a lamp 
bulb and an 
optical fiber. Four memory supporting rods are installed on the lower portion of the energy accumulator, the wave 
electric generator is installed on the lower portions of the memory supporting rods, the concave cover is installed on the upper portion of the energy accumulator, the support column and the 
optical fiber are installed on the concave cover through a triangle bracket, and the lamp 
bulb is installed on the support column. Silver is plated on the inner layer of the concave cover, the light converging spot of the concave cover enters the 
optical fiber and emits out from the head portion of the optical 
fiber. The wave 
electric generator and the energy accumulator are connected with the lamp 
bulb through wires, and a photosensitive sensor is arranged inside the energy accumulator. The memory supporting rods are shake-type memory rods, the deformation frequency is 7-9HZ, and therefore the memory supporting rods can lie flat on the sea surface to reduce influence of 
waves and prolong the service life. The 
beacon for the ship navigation can be self-powered or reflects lights, and therefore the beacon for the ship navigation is free from bondage of a power supply. Besides, the beacon for the ship navigation is special in structure and long in service life.
