DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for preventing pirates from illegally entering a ship.

[0002]

2. Description of the Related Art In recent years, pirate cases have frequently occurred in straits such as Southeast Asia. Pirates are a fully armed group, and can rob crews of goods and cargo, or even ships, and their countermeasures are struggling. Pirates sneak up on a small vessel from behind, sneak up on a rope-attached anchor, hook it onto the handrails on the stern upper deck, and use it to hang a rope ladder on the voyage at night. Cases-most.

As a conventional measure, when a pirate is detected, a siren is sounded and the ship is moved backward. Alternatively, repelling means such as discharging water or throwing back an anchor are employed. As for the detection, there are known detection methods such as installing an interception sensor or night vision camera, passing a weak current to the handrail, and using electric signals.However, it is accurate over a wide area from above the stern upper deck to the sea surface directly below. However, it was not able to respond sufficiently.

[0004] In addition, these exploration means sometimes react to foreign substances such as birds and waves, and there is no other way than to illuminate the lights at night and to provide watchmen. In addition, if the approach of a pirate is detected early, the repulsion means described above can be taken, but if it is overlooked or the detection is delayed,
Pirates jump in at once, and once they have been fully armed, there is no way to respond.

SUMMARY OF THE INVENTION It is an object of the present invention to provide an illegal boarding prevention device capable of reliably detecting the approach of a pirate and automatically preventing illegal boarding.

[0006]

The present invention relates to a device for preventing illegal entry into a ship, wherein a handrail cover that covers the handrail is detachably connected on an upper deck of the ship, and has a surface shape on which an anchor slips. And attached. In addition, when the handrail cover is attached, a signal line cut by the anchor is provided when the anchor is hooked on the inner surface of the ship, and an alarm is issued by cutting the signal line.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view schematically showing an illegal entry prevention device according to the present invention. FIG. 2 is a sectional view of the device, and FIG. 3 is a detection and alarm circuit diagram of the device. In the figure, reference numeral 1 denotes a handrail cover, which is formed in a semi-elliptical cross section. Reference numeral 2 denotes a support provided at one end of the handrail cover 1, and reference numeral 3 denotes a mounting plate provided at the other end of the handrail cover 1.

The handrail cover 1 may have a semi-elliptical cross section, a semi-circular cross section, or a polygonal cross section as shown. In short, it is sufficient if the surface shape does not have any protrusions or depressions and does not catch the anchor. Further, it is necessary that the anchor should not be depressed or deformed even if it hits, and an iron plate is used.

Further, the handrail cover 1 is a divided body having a short length so that installation and removal can be easily and quickly performed, and the divided body is connected and attached. The end of the continuous portion may be a butt type, or the end portions may be overlapped with different diameters. If you overlap the ends,
Position adjustment at the time of attachment becomes easy.

Reference numeral 4 denotes a guide ring for the signal line 5 fixed to the outer surface of the handrail cover 1 on the side of the mounting plate 3. A signal line 5 is extended through the guide ring 4. Signal line 5
In this case, a coated wire is used, but a wire which is strong enough to be cut immediately when a hooked anchor is pulled is used. Reference numeral 6 denotes a stern end steel plate, 7 denotes an upper deck, and 8 denotes a handrail erected on the upper deck 7.

FIG. 3 shows a detection and alarm circuit. S is a detection circuit, which is a battery 9 which is a power source of the circuit, and which is O
N, OFF operation switch 10 and electromagnetic relay 11
have. The signal line 5 is connected to the detection circuit S, and a current is supplied from the battery 9 through the electromagnetic relay 11.

A alarm circuit is connected to the detection circuit S so as to be directly connected to the battery 9 of the detection circuit S. The plurality of alarm circuits A are arranged in parallel.
Reference numerals 12 and 13 denote B contacts of the electromagnetic relay 11, respectively, which are provided in the alarm circuit A. Reference numerals 14 and 15 denote alarm devices, which are also provided in the alarm circuit A, and operate alarm devices provided on the stern upper deck and on the bridge. Reference numeral 16 denotes an operation switch provided in the alarm circuit A as appropriate.

The configuration of the present invention is as described above. Next, the installation and operation of the device for preventing illegal entry according to the present invention will be described. First, when approaching a sea area where a pirate may appear, a handrail cover 1 is placed so as to cover the handrail 8 at the stern, and the end is supported on the stern end steel plate 6 by the cradle 2 and the other end is provided. Is fixed to the upper deck 7 with bolts.

The handrail cover 1 is arranged without a gap so as to cover all the handrails 7 in the so-called pirate entry zone, which is behind the accommodation area of the ship. Note that a handrail cover curved or bent in the length direction can be used at the corner portion of the handrail arrangement. Also,
If the diameter of the joining portion of the handrail cover 1 is changed to be overlapped, the position adjustment at the time of mounting can be easily performed.

After the handrail cover 1 is attached in this way, the signal line 5 is passed through a guide ring 4 attached to the surface of the handrail cover 1 on the inner side of the ship, and the signal line 5 is passed through the entire length of the installed handrail cover 1, that is, Over the entire length of the pirate entry zone. The signal line 5 extending over the entire length of the handrail cover 1 has both ends connected to the detection circuit S.

In this state, even if a pirate approaches and throws an anchor, the handrail cover 1 has a semi-elliptical cross section and no protrusions or depressions. From there, there is no place where the anchor is caught,
Even when the anchor is pulled, the anchor slips on the surface of the handrail cover 1 and falls down.

On the other hand, since the signal line 5 is connected to the detection circuit S, if the operation switch 10 is turned ON, a current always flows from the battery 9 to the signal line 5 and the electromagnetic relay 11. At this time, since the B contacts 12 and 13 of the electromagnetic relay 11 are open, no current flows through the alarm circuit A.

However, when the pirate throws up the anchor and pulls it, the anchor slips on the surface of the handrail cover 1, but at this time, it gets caught on the signal line 5 and cuts it. Since the guide ring 4 only passes through the signal line 5, it may be a thin ring. When the anchor is caught on the ring, the ring is broken by the anchor. Further, it is possible to make the mounting shape such that the anchor is hard to be caught.

When the signal line 5 is disconnected, the electromagnetic relay 11
Current stops flowing to the B contact 12
13 is closed, a current flows through the alarm circuit A, and the alarm
Activate 4 and 15 to issue an alarm. For example, a loud sound is generated at the stern to intimidate the pirate, and a sound is generated at the bridge to notify the shift personnel, and all crew members are shifted to a high alert system according to instructions from the shift personnel.

It should be noted that the device for preventing illegal entry does not hinder the navigation of the ship, and when the ship leaves, it only sails until entering the next port, and does not perform any other work. A vessel navigating a sea area where a pirate may appear can be equipped with this device in advance when sailing.

[0021]

According to the present invention, since the handrail at the stern portion is covered with the handrail cover having a cross-sectional shape so that the anchor is not caught, illegal landing of pirates by the anchor can be automatically prevented. In addition, a signal line that is caught by the anchor and cut by the anchor is stretched over the inner surface of the handrail cover on the ship, and an alarm is issued when the signal line is cut, so that it is possible to reliably detect the approach of the pirate. it can.
