Abstract

The invention relates to an auxiliary light mast for mounting a ship navigation signal light. Two auxiliary light masts are symmetrically installed on the two sides of a compass deck (A), and each auxiliary light mast comprises a mast body (1), a vertical ladder (2), a guard circle (3) and a plurality of supports (8), wherein the vertical ladder (2) and the guard circle (3) are fixed to the mast body (1), and the multiple supports (8) are fixedly connected to the mast body (1) at intervals from top to bottom; the upper end and the lower end of each support are each provided with a light base (5) in the vertical direction, and the bottoms of the two light bases at the upper end and the lower end are opposite; and the navigation signal lights (9) are installed in the light bases, the two auxiliary light masts are each provided with one navigation signal light internally provided with a 180-degree light shading plate (10), the light shading plates are arranged on one side facing the ship middle line, and the distance between the adjacent supports is larger than or equal to 2000mm. By using the auxiliary light mast, the arrangement difficulty of a sound and light signal system is reduced, the design difficulty of a radar mast is reduced, and the dead zone of an all-round light is reduced.

Description

technical field [0001] The invention relates to a carrier for a ship's acousto-optic signal arrangement, in particular to an auxiliary light mast for installing a ship's navigation signal light. Background technique [0002] The ship's navigation signal lights need to meet the International Regulations for Preventing Collisions at Sea (Convention on the International Regulations for Preventing Collisions at Sea, 1972, COLREG for short) and the requirements of major classification societies, maritime organizations, and canal authorities. The International Rules for Preventing Collisions at Sea requires the arrangement of the following lights: Article 27 stipulates: "A ship out of control shall display: two vertical all-round red lights at the most visible place"; Article 28 stipulates: "Ships limited to draft In addition to the lights specified in Article 23 for motor ships, three all-round red lights or a cylinder can be displayed vertically at the most visible place." In ad...
