Crashworthy anti-sinking multi-cabin buoy

Abstract

The invention discloses a crashworthy anti-sinking multi-cabin buoy which comprises a buoy body. A lamp bracket is fixedly arranged on the upper portion of the buoy body and connected with a lamp, a tail pipe is fixedly arranged on the lower portion and connected with a balance weight iron ring, the buoy body is of a hollow structure, a clapboard is arranged in the buoy body and divides an inner cavity of the buoy body into at least two sealed cabins, a rubber retainer is fixedly installed above the water line of the buoy body in a sleeved mode, and a shell of the buoy body comprises a steel plate layer and a glass fiber reinforced plastic layer from inside to outside. The glass fiber reinforced plastic layer is adopted for being combined with the steel plate layer, material is saved, self weight is reduced, maintenance is convenient, and operating cost is reduced. The rubber retainer improves crashworthiness of the buoy and prolongs service life of the buoy. Due to the subdivision design inside the buoy body, buoy sinking is prevented, other auxiliary electronic devices of the buoy can be also effectively protected, ship collision losses are reduced, and working reliability of the buoy is effectively enhanced.

Description

technical field [0001] The invention belongs to a marine navigation device, in particular to an anti-collision and anti-sinking multi-chamber buoy. Background technique [0002] A buoy is a kind of navigation mark floating on the water surface, which is anchored at a designated position to mark the range of the channel, indicate shoals, obstructions or indicate special-purpose surface navigation aids. The International Association of Aids to Navigation (IALA) pointed out in the "Guide to Aids to Navigation" that "for many years to come, traditional navigation marks will still function, and buoys will still be needed to mark the boundaries of waterways, identify existing sunken ships and other maritime hazards, and serve as a confirmation Data from Electronic Aids to Navigation". Traditional steel buoys are bulky and easy to corrode, requiring large professional buoy ships for hoisting, deployment and transportation, as well as regular replacement for sandblasting, rust remo...

AI Technical Summary

Problems solved by technology

At present, most of the relevant research is still limited to the modification of FRP materials and the research and development of alternative materials, such as ultra-high molecular weight polyethylene (CMB) assembled plastic buoy products. The cost price of the material is relatively high, and the steel buoy cannot be completely replaced for the time being
