Abstract

PURPOSE:To facilitate searching operation at a maritime accident and assure the safety of a navigator, by providing a radio transmitter in a life jacket to use the transmitter as a maritime disaster prevention alarm. CONSTITUTION:A radio transmitter is provided in a life jacket 4. The antenna 1 of the transmitter comprises four radial antenna units connected to one another. When a person wearing the life jacket 4 is in the sea water, a part of the antenna 1 is located in the air to transmit electromagnetic waves. The transmitter comprises the transmission antenna 1, an electromagnetic wave generator 2 and a water detector 3 and surely functions through a simple construction. The waves transmitted from the transmitter provided in the life jacket 1 are received by the antenna of a ship or the like so that an alarm is raised.

Description

Detailed Description of the Invention The present invention detects water landing when a crew member or passenger of a ship carries a wireless transmitter and unexpectedly falls into water or seawater (hereinafter referred to as seawater). By detecting this, a signal is emitted or stopped, and when a radio receiving device installed on a ship or the like receives the signal or stops the continuing signal, the alarm unit issues an alarm.
The purpose is to provide a marine accident prevention device that notifies crew members or passengers who have fallen into seawater.

As a marine accident prevention device, if a crew member or passenger falls from a ship, etc. into seawater, etc., one device detects water and starts transmitting, and the other detects water landing in seawater, etc. and starts transmitting. However, since these marine accident prevention devices are generally attached to the crew's work helmets and waist belts, there is a possibility that the crew member may fall from the vessel or the like into seawater, etc. Even if a signal informing the crew is received by the receiving device, an alarm is issued, and rescue operations are carried out, the crew member may be submerged in seawater or the like, making search efforts difficult, or even if found, it may be too late and the crew member may have already drowned. is possible.

Furthermore, when a person lands in seawater or the like, an electromagnetic wave is transmitted, and the fall is confirmed by a wireless receiver installed on a ship or the like. A radio transmitter that uses an electromagnetic wave carrier method that transmits data when it lands on water has a serious defect in that if the transmitting antenna is submerged in seawater or the like, the electromagnetic waves will not be transmitted.

In view of these two points, the present invention incorporates a radio transmitter into a life jacket and uses it as a marine accident prevention alarm, so that even if a person falls from a ship or the like into sea water, the person will not drown, and the life jacket will be accurate. The aim is to provide something that will work effectively, shorten search operations, and greatly contribute to rescuing people who have fallen without any harm to their lives.

Embodiments of the present invention will be described below with reference to the drawings.

1 and 2 show an embodiment of the present invention in which an electromagnetic wave carrier type transmitter is attached to a life jacket, and Figure 1a shows a life jacket 4 with a built-in electromagnetic wave carrier type transmitter, Antenna 1 is a combination of four rice-shaped antennas, and if the person on the left 7 falls into seawater and lands on water while wearing a life jacket 4, a portion of antenna 1 will appear in the atmosphere and begin transmitting electromagnetic waves. There is. B in FIG. 1 is a diagram of a transmitter built into the life jacket 4, in which 1 is a transmitting antenna, 2 is an electromagnetic wave generating section, and 3 is a water landing detection section. FIG. 2a is a diagram in which the crew member 7 is wearing a life jacket 4 containing an electromagnetic wave carrier type transmitter. FIG. 2 is a partially cutaway view of the life jacket 4, showing an embodiment of the present invention in which a cylindrical electromagnetic wave generating section 2 and a rod-shaped antenna 1 are built into the life jacket 4.

FIG. 4 shows an embodiment of the present invention in which an ultrasonic generator 6 and a water landing detector 3 are attached to a belt-type life jacket 6.

Figure 5 shows the situation when a crew member 7 falls into the ocean after landing on water and is wearing a life jacket 4 or 6 that has a built-in transmitter that emits electromagnetic waves. The electromagnetic waves received by the antenna 8 are transmitted to the receiving device, and an alarm is issued.

Figure 6 shows the situation when a crew member 7 falls into the ocean while wearing a life jacket 9 that has a built-in transmitter that stops emitting electromagnetic waves by landing on water. If the signal is being output but the transmitter stops transmitting, a warning will be issued on the ship.

FIG. 7 shows an old situation in which a crew member 7, wearing a belt-type life vest 10 with a built-in ultrasonic generator 6 that generates ultrasonic waves, fell into seawater after landing on water.
The ultrasonic waves generated by the ultrasonic generator 6 are received by an ultrasonic receiving device 11 attached to the bottom of the ship, and an alarm is issued.

As described in detail above, according to the present invention, the life jacket r (with a built-in radio transmitter) prevents drowning even if one falls from a ship or the like into seawater, operates accurately, and shortens search operations. can be rescued.

In addition, crew members and passengers will get into the habit of wearing life preservers at all times, and their safety awareness will be improved.
