Marine self-return floating beacon

The invention belongs to offshore engineering structure fields, are related to a kind of marine self-return floating beacon, including GPS positioning system, further include superposed tower body and the buoyancy tank system positioned at lower part；Tower lamp is equipped at the top of tower body, tower body bottom is fixed on the center of buoyancy tank system, the tower body is made of the stacking of multistage tower stature, each tower stature includes the ring support of a pair of distribution symmetrical above and below, more supporting rods are provided between a pair of of ring support, the supporting rod staggered is latticed；Buoyancy tank system includes the buoyancy tank that seven cylindrical floating drums form a regular hexagon, and tower body is mounted on the floating drum of center, and propeller is equipped under floating drum.Sea self-return floating beacon provided by the invention, GPS technology is used on beacon, in conjunction with floating structure, solves the problems, such as that traditional beacon bad adaptability, flexibility are low well.
