Telescopic navigation aid sign display board

Abstract

The invention provides a telescopic navigation aid sign display board which comprises a sign display board, a controller and a solar cell panel. The sign display board is simultaneously provided with a navigation sign and a restricted navigation sign or is respectively provided with the navigation sign and the restricted navigation sign, and telescopic devices are arranged in the side length of the navigation sign and the side length of the restricted navigation sign. The telescopic devices control the navigation sign and the restricted navigation sign to extend by several meters in the side length direction, and the telescopic devices are connected with the controller. A plurality of lamp beads are mounted on the surfaces of the navigation sign and the restricted navigation sign, and the lamp beads are connected with the controller and the solar cell panel. The controller is connected with a transmission module arranged in the sign display board. According to the navigation aid sign display board, a sleeve design is adopted, the navigation sign and the restricted navigation sign can be prolonged, the navigation aid sign display board is suitable for various marine shipping requirements, shipping accidents can be reduced, the shipping safety can be enhanced, and the navigation aid sign display board can meet different requirements of customers.

Description

technical field [0001] The invention relates to the technical field of maritime navigation aids, in particular to a retractable navigation aids display board. Background technique [0002] In combination with the actual situation of the country, China formulated the national standard (GB4696-84) of "Maritime Aids to Navigation in China's Sea Areas" (GB4696-84) in 1984 on the basis of the principles of the International Sea Area Maritime Navigation Mark System (A region), and since 1985 August China's navigation mark system will be implemented from January 1, and it will apply to all buoys and fixed marks in water in China's sea area and its seaports and estuaries (excluding lighthouses, fan-shaped beacons, guide beacons, lightboats and large navigation buoys). The method of expressing the characteristics of the sign is expressed by the color and shape of the sign during the day; at night, it is expressed by the light quality of the sign, that is, the light color, light flash...
