A new type of port navigation mark

Abstract

The invention relates to the technical field of navigation aids, in particular to a novel harbor navigation aid. The specific technical solution is: a new type of port navigation mark, including a hollow navigation mark body, a mark pole fixed on the top of the mark body through multiple support rods, and a beacon light set on the top of the mark body. The bottom of the hemisphere is provided with a circular groove, the bottom of the hemisphere is provided with a curved plate that fits the bottom of the hemisphere, the bottom of the curved plate is fixed with a fixed column, and the top of the fixed column is vertically provided with a column that runs through the curved plate Groove, the hemisphere is fixed on the bottom of the cylindrical groove by a chain, the first through hole communicating with the cylindrical groove is horizontally provided on the side wall of the fixed column, a bolt is arranged in the first through hole, and the bolt passes through the chain and is fixed on the On the inner wall of the cylindrical groove symmetrical to the first through hole, sinkers are fixed at the bottom of the fixing column. The invention solves the problem in the prior art that the navigation mark cannot be used normally under the condition of strong wind and big waves.

Description

technical field [0001] The invention relates to the technical field of navigation aids, in particular to a novel harbor navigation aid. Background technique [0002] Navigation mark is the abbreviation of navigation mark, which refers to the mark indicating the direction, boundary and obstruction of the navigation channel, including river crossing mark, coastal mark, guide mark, transition guide mark, head and tail guide mark, side mark, left and right navigation mark, position indicating mark, Flood marks and bridge and culvert marks are artificial marks that help guide ships to navigate, locate and mark obstructions and express warnings. [0003] The buoy can be divided into fixed buoy and floating buoy on the water surface. The fixed buoy is fixed at the port and has a good stability effect. However, due to the wind and waves in the port, the buoy is easy to break or fall down, thus affecting the ship's navigation direction. distinguish. The floating buoy is composed of...
