Description

Detailed Description of the Invention (Field of Industrial Application) The present invention relates to a structure for securing a floating body equipped with an emergency position indicating radio (EPIRB) etc. to a ship, etc. The present invention relates to an automatic detachment device and an emergency communication device that can be automatically detached from a ship's hull.

(Prior art) When a ship, etc. encounters an emergency situation such as capsizing or sinking, it has been equipped with an ordinary position indicating radio (El) IRB as a means to notify the distress area of the ship, etc. A floating body is used.

In recent years, as marine accidents have been on the rise, the importance of emergency location indicating radios has rapidly increased as a means of instantly reporting the distress location of capsized or sunken vessels and enabling prompt rescue measures. Various systems have been developed that eject a floating body containing a wireless communication device out of the ship when an abnormality occurs in the ship's hull, and the radio waves from the wireless communication device are generally relayed to a desired point via an artificial satellite. .

FIG. 3 is an explanatory diagram of the configuration of a conventional automatic detachment device, in which a radio housing 3 that also serves as a floating body is placed inside a storage box 2 fixed to the hull l.
is housed and held via the cushion 4. A transmitter (not shown) is housed in the radio housing 3.

When a ship encounters an emergency situation, a crew member or the like can take out the wireless device housing 3 (floating body) and throw it into the sea, or place it on a liferaft, allowing it to function properly.

However, in the case of dσ failures, which often occur suddenly and end in an instant, conventional position indicating radios, which require operations such as take-out and put-in using a boarding IJ, are useful. -The 17 types are limited to extremely limited cases, and in reality, in many cases, they remain in the storage box even after a shipwreck and end up not functioning for rescue purposes.

Even if there is a margin of time between the occurrence of an accident and the sinking, there may be cases where people are preoccupied with escaping and forget to take out the bodies, or there are cases where it is physically impossible to take out the bodies due to fire, flooding, etc. In many cases, floating objects were not introduced due to reasons such as it being impossible to do so.

In any case, the conventional emergency position indicating radio equipment, which requires manual extraction and insertion into the sea, has various problems in terms of performance, and it can lead to the loss of human life. It was leading to damaging results.

(Purpose of the Invention) The present invention was made in view of El, and automatically detaches from the hull when an abnormality occurs such as capsizing or sinking the ship without requiring manual extraction or putting it into the sea. The object of the present invention is to provide an automatic evacuation device and an emergency transmission device that can notify a rescue organization of the location of a 11g11 site by releasing it into the sea.

(Summary of the Invention) In order to achieve the above object, the automatic release device of the present invention maintains the four bodies on the support stand at all times, and when the body is immersed in water and the water pressure exceeds a predetermined value. An automatic release device for ships equipped with a water pressure release device that operates to release the floating body, the automatic release device having five base ends pivotably supported to be vertically rotatable, and the other end supporting the floating body. The release device consists of a rotating arm that presses the upper part of the floating body on the table, and a wire stretched between the rotating arm and the water pressure release device to hold the rotating arm in the floating body holding position. It is characterized in that during operation, the tensioned state of the wire rod is released to open the rotating arm to a rotatable state.

In another embodiment of the present invention, the rotating arm is pivotably supported in a direction other than the vertical direction.

It is characterized in that when the floating body rotates in the other direction, the engagement IE of the floating body is released.

Further, the floating body is equipped with an emergency communication radio and a reed relay that is activated when the floating body is removed from the magnetic field, and when the floating body is supported on the support base, the reed relay is provided on the support base side. The reed relay is located close to the permanent magnet, and is activated when the reed relay is removed from the magnetic field of the permanent magnet to activate the emergency communication pre-lit device.

(Embodiments) Hereinafter, the automatic detachment device and emergency communication device of the present invention will be described in detail based on embodiments shown in the accompanying drawings.

1(a) and fb) are a front view and a plan view showing the configuration of a first embodiment of the present invention, in which an emergency communication A floating body 15 housing a radio device (transmitter, receiver) as a device is supported by an automatic release device 16.

The detachment device 16 has a support frame 18 at its tip that fits around the outer periphery of a lamp 17 protruding from the head portion of the γγ body I5 placed on the support table 2, and also has a base end 19a connected to the wall portion I+. a rotating arm 19 pivotably supported to be able to move up and down, and a hydraulic release device 20 disposed at the base end of the support base 2;
It has a lobe (wire rod) 22 whose upper end is fixed to a proper position (for example, an intermediate position) of the rotating arm 19 and whose lower end is supported by a hydraulic release device 20 .

The hydraulic release device 20 has been developed in various forms, and in this embodiment, it is not limited to a specific form. cutter 30
are arranged close to each other, and when the cutter 30 is not in operation, the cutter 30 is retracted by the lock claw 32, and when the cutter 30 is in operation, the lock by the lock claw 32 is released by water pressure, and the cutter 30 is projected to cut the lobe 22. Use what you have configured. The lock claw 32 is normally held in a position where the cutter is locked by a pressure-sensitive member (not shown), such as a bellows, but if part or all of the ship's hull sinks or the automatic release device 16 is submerged in the sea. In such a case, the pressure-sensitive actuating member is contracted by water pressure to release the locking of the opening/shaft pawl 32 and enable the cutter to protrude.

The water pressure release device 20 is configured so as not to be activated by external forces such as vibrations of the hull, but is configured to be activated when the automatic release device 16 is submerged in the sea.

In the above, the rotating arm 19 is configured to release the engagement 1F of the ramp 17 at the top of the floating body 15 when it rotates upward, but a notch is provided in the support frame I8 and the arm 19 can be moved up and down. The floating body may be pivoted so as to be rotatable in a direction other than the above direction, for example, the horizontal direction, and the floating body may be unlocked when the arm 19 rotates in the horizontal direction. Further, the position at which the arm locks the floating body is not limited to the top, but may lock at a protrusion, hook, etc. provided at a location other than the top.

As the 77 body 15, for example, as shown in the figure, a buoy having a dome-like upper half and a cylindrical lower half can be assumed.

The exterior is made of reinforced resin.6 The antenna is housed inside the tom, and the lower half houses the radio (oscillator, receiver) and battery. When floating, the lower cylindrical part and the lower part of the dome are submerged in seawater, but most of the dome is located above sea. The lamp 17 on the top of the dome is a flashlight, and by blinking it, the position of the buoy can be confirmed in the darkness at night.

Furthermore, as a radio device built into the floating body 15, for example, as shown in FIG. , as shown in Figure 2, a receiver is installed in addition to the transmitter to receive information from the artificial satellite,
It may also be configured to issue an emergency signal in response to an interrogation signal using a transponder system.
