Marine Horn

Marine horn is a set of sound signal equipment, general use compressed air or high pressure steam as power, have button and hand cable two type;

Fog horn is a set of ship automatic sound system design in fog navigation, can automatically control the whistle from the specified navigation signal.

Marine fog horn is sailing in fog environment used as signal whistle.Fog horn is a kind of signal. Usually whistle a minute,stop a minute, or whistle 30 seconds, stop 30 seconds cycle.


Marine Horn can be divide into Piston horn and Air Horn

 

Marine Piston Horn

Ship piston horn, automated intelligent control, is a kind of advanced and practical new type of modern ship navigation in fog equipment, is the upgrading product of aerial fog whistle.

major component:
marine piston electric horn consist of horn Sound system and automatic control system two parts.
Sound system mainly consist of motor, driven gear, eccentric shaft, piston, piston cylinder, vocal diaphragm, resonator, speakers and other parts, by mechanical connection, by mechanical connection, the components as assembly with independent functions.

Working principle
Through the MCU, the system automatically according to the actual environment output signal, driving the motor running. The vocal system use motor as the prime mover, through the gear drive high-speed rotating eccentric shaft, the eccentric shaft drives piston in cylinder seat make high-frequency reciprocating movement, compressed the air in chamber consist by piston and piston cylinder, driving sound diaphragm phonation. The voice is strengthened by resonance effect of the horn resonator, a fog signal corresponding.

Marine Air Horn

Ship fog horn is compressed air as power, driving the sounding body make fog signal. Therefore, it is necessary to ship with air compressor, a high volume of storage tank for gas transmission pipeline.

This product is suitable for medium and large vessels;
