Novel port navigation mark

Abstract

The invention relates to the technical field of navigation marks, in particular to a novel port navigation mark. According to the specific technical scheme, the novel port navigation mark comprises ahollow navigation mark body, a mark rod fixed to the top of the mark body through a plurality of supporting rods, and a mark lamp arranged at the top of the mark rod. A hemispheroid is arranged at thebottom of the mark body, a circular groove is formed at the bottom of the hemispheroid, and an arc-shaped plate attached to the bottom of the hemispheroid is arranged below the hemispheroid. A fixedcolumn is fixed at the bottom of the arc-shaped plate, a cylindrical groove penetrating through the arc-shaped plate is vertically formed at the top of the fixed column, and the hemispheroid is fixedto the bottom of the cylindrical groove through a chain. A first through hole communicated with the cylindrical groove is transversely formed on the side wall of the fixing column, a plug pin is arranged in the first through hole, penetrates through the chain and is fixed to the inner wall, symmetrical to the first through hole, of the cylindrical groove, and a sinking stone is fixed to the bottomof the fixing column. According to the novel port navigation mark, the problem that in the prior art, the navigation mark cannot be normally used under the condition of strong wind and strong waves is solved.

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...
