Height-adjustable ship signal lamp

Abstract

The invention relates to a height-adjustable ship signal lamp which comprises a fixing mechanism, an indicating mechanism and a lifting mechanism. The fixing mechanism comprises a first sleeve and a fixing disc, and the fixing disc is installed at the bottom of the first sleeve. The lifting mechanism comprises a motor, a threaded rod, a threaded sleeve and a second sleeve, the motor is connected with the threaded rod, the exterior of the threaded rod is connected with the threaded sleeve through threads, the exterior of the threaded sleeve is connected with the second sleeve, and the second sleeve is slidably mounted in the first sleeve; the indicating mechanism comprises an electric wire, a guiding device and an indicating lamp, the indicating lamp is arranged on the upper portion of the lifting mechanism, the guiding device is installed on the outer wall of the first sleeve, and a gap for the electric wire to penetrate is reserved between the guiding device and the first sleeve. The motor is used for driving the threaded rod, so that the height of the indicating lamp can be adjusted at will; under the action of a roller and the electric wire, a connecting wire cannot be knotted when the height of the indicating lamp is adjusted; meanwhile, due to the arrangement of a plurality of sleeves, internal parts can be sealed and protected.

Description

technical field [0001] The invention relates to the technical field of ship signal lights, in particular to a height-adjustable ship signal light. Background technique [0002] Ship signal lights indicate the state of the ship or provide a type of lamp with light language. There are all-round lights, anchor lights, flash lights and communication flash lights, etc.; all-round lights: can display uninterrupted white, red, green or yellow lights in a 360° horizontal arc, and the visible distance is 2 to 3 nautical miles; anchor lights: For ships at anchor, two white lights are hung on the most visible places at the bow and stern from sunset to sunrise; flashing lights: installed above the side lights, when the ship turns left and right, it emits red light at regular intervals Or green light all-round signal light; communication flash: also known as Morse signal light, which is manually operated and emits white light according to the Morse code signal, for short-distance commun...
