Anti-drifting navigation mark for marine traffic

Abstract

The invention discloses an anti-drifting navigation mark for marine traffic. The mark comprises a cylindrical base shell, a circular-truncated-cone-shaped pipe body is fixed to the outer wall of the top of the base shell through bolts. A top plate is welded to the outer wall of the top of the pipe body; four indication boards which are annularly distributed at equal intervals are welded to the outer wall of the top of the top plate. Indicating marks are adhered to the outer walls of the four indicating boards; a same mounting plate is welded to the outer walls of the tops of the four indication boards, two vertical rods are welded to the middle of the outer wall of the top of the mounting plate, a same wind direction plate is welded to the top ends of the two vertical rods, streamline sidewings are welded to the outer walls of the two sides of the wind direction plate, and the two side wings are located at the positions close to one end of the wind direction plate. The navigation markis used for providing sea route information for passing ships in marine traffic, the navigation mark has a good drifting prevention function, and the navigation mark can still be kept within a certain range as much as possible in stormy weather so as to provide accurate information.

Description

technical field [0001] The invention relates to the technical field of navigation aids, in particular to navigation aids used for marine traffic to prevent drifting. Background technique [0002] Aids-to-navigation is the abbreviation of aids to navigation. It is a sign indicating the direction of the channel, boundaries and obstructions, especially in maritime traffic. At present, most of the existing buoys are floating on the sea when they are working. Another part of the navigation mark is towed by the anchor and the stay rope, and the above two kinds of navigation marks cannot avoid the drift of the navigation mark during the work process. [0003] After retrieval, the Chinese patent number is CN 105947120B, which discloses a small emergency buoy, which includes: an upper buoy and a lower buoy, the upper buoy is filled with polyurethane foam material, and the lower buoy is hollow inside. There are 2-4 drainage holes on the side wall, and two lifting lugs made of steel b...

AI Technical Summary

Problems solved by technology

The emergency buoy in the above-mentioned patent has the following deficiencies: there is no wind without waves, and in the weather with wind and waves, the buoy cannot prevent itself from drifting with the waves, and the drift of the buoy will make it impossible for passing ships to obtain route information
