1. A maritime distress signal transmission device comprising:
a holder-cradle; and
a main body which is coupled to the holder-cradle and transmits a rescue signal to an arbitrary receiver using a preset frequency band,
wherein the main body includes a main body housing which includes a moisture sensor disposed on a rear surface thereof and configured to detect entry into water and in which a Global Positioning System (GPS) receiver configured to receive GPS signals, and a time to speech (TTS) signal convertor configured to convert the GPS signals to a TTS voice signal, a main body cover which covers an upper surface of the main body housing to perform a waterproofing function of preventing water from being introduced thereinto and accommodates an antenna which is disposed on an upper surface and transmits the TTS voice signal through a preset frequency band, and an antenna cover which hides and protects the antenna accommodated in the main body cover and in which a first hooking hole is formed in a direction perpendicular to an extension part formed by extending one side of the antenna cover,
the holder-cradle allows the main body to be seated thereon and includes a second hooking hole is formed upward at one side thereof,
a separation part including a double coupling part in which a first hooking part to which the first hooking hole of the antenna cover is coupled, a second hooking part to which the second hooking hole of the holder-cradle is coupled, and a rack gear rail which is moved in one direction by operation of a pinion gear connected to a motor provided in the accommodation part of the main body housing are formed and which is moved in the one direction according to operation of the rack gear to separate the holder-cradle and the antenna cover is provided,
the holder-cradle and the antenna cover, which are coupled to the double coupling part, are sequentially separated according to detection of the moisture sensor to float the main body on a water surface, and
the TTS voice signal is wirelessly transmitted as a signal in a preset frequency band to an arbitrary remote receiver through the antenna protruding upward due to the separation of the antenna cover.
