Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an underwater accident prevention device used for safe navigation of ships.

[0002]

2. Description of the Related Art In recent years, with the spread of automatic steering devices especially on ships, the number of accidents involving crew members falling into the sea, which is not due to marine accidents, tends to increase. The reality is that many lives have been lost.

Most of them are small fishing boats, and they often fall accidentally during fishing work, and other crew members notice this.
There are also many opportunities to be rescued by asking for help.

Conventionally, as a countermeasure against this kind of accident, a small radio which emits a weak radio wave is carried by a crew member, while a scanning receiver capable of identifying the individual radio waves is arranged in the steering room. If one of them accidentally falls into the sea, the radio wave from the small radio will be cut off, so the scanning receiver will detect the crew member's fall into the sea, and the crew member's personal name will blink on the display panel and the buzzer will sound. It is known that the crew member is informed of the fall accident by such means, and after that, the other crew members make an emergency stop of the ship and perform a rescue operation.

[0005]

However, this accident countermeasure is ineffective in a small-sized ship with only one crew member when the fall accident occurs, the ship becomes unmanned and runs away unattended. Even small vessels are getting faster, and even when the crew falls and the ship comes to an emergency stop, the place where it crashed can be quite far from the place where the ship stopped, waves, It is usually difficult to swim to the location of a ship because it is swept away by tidal currents and winds, and this can lead to loss of precious lives.

Even if a ship has several crew members, there are many cases where there is no room to constantly check the safety of other crew members during operation, so there is a risk similar to that of a one-seater ship. I am sexually charged.
