Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a device for preventing illegal entry into a pirate ship.
[0002]
[Prior art]
In recent years, pirate incidents have frequently occurred in straits such as Southeast Asia. Pirates are a fully armed group, and may take the crew's money and cargo, or even ships, and countermeasures are difficult.
The pirates, while the ship was anchored, climbed up the anchor chain and raised the anchor with the rope from the outside of the ship, hooked the anchor to the railing of the ship, based on this, hung a rope ladder, There is a case of getting in at a stretch.
[0003]
For pirates climbing along the anchor chain, a means is taken to cover the hose pipe, which is a passage through which the anchor chain goes out of the ship, to close the entrance.
However, it was powerless against pirates who climbed anchors. In particular, it was completely defenseless against pirates who hooked anchors to ships that were navigating at night, rather than sniffing them with small ships.
[0004]
Conventionally, 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 anchors are taken, but pirates who are fully armed are opponents, and there is a limit to the response of these crews. It was not a means.
[0005]
In addition, for detection of pirate intrusions, blocking sensors and night vision cameras are installed, weak current is passed through the handrail, and detection methods using electrical signals are known, but the sea level directly below the ship's upper deck It was not able to respond accurately and adequately over a wide area towards the sea, and these exploration means may react to foreign objects such as birds and waves, surely illuminate the light at night, There was no other but to put a watchman.
[0006]
Furthermore, if the approach of the pirate is detected early, the repelling means described above can be taken, but if the pirate approach is missed or the detection is delayed, the pirate will board at once, and once it is boarded by a fully armed pirate The current situation is that there is no means to cope with it.
[0007]
[Problems to be solved by the invention]
It is an object of the present invention to obtain an effective illegal entry prevention device that can reliably detect the invasion of pirates and can automatically prevent illegal entry.

[0021]
The configuration of the present invention is as described above. Next, the operation and action will be described.
When the anchor is thrown up from outside the ship, the anchor is caught by the trigger 6. When this anchor is pulled, the trigger 6 is pinned 7 to the support column 4, so that it is rotated to the ship side 2 against the spring 9.
[0022]
When the trigger 6 is rotated, the movement of the lever 8 causes the trigger rotation detection mechanism 10 to detect the rotation of the trigger 6, and the opening / closing valve 14 corresponding to the trigger 6 and the pressurized tank 16 of the hot water supply system. The electromagnetic on-off valve 17 is opened. As a result, the hot water stored in the pressurized tank 16 is supplied from the hot water production system to the hot water discharge pipe 11 corresponding to the rotated trigger 6 through the hot water supply main pipe 15 and the hot water supply pipe 13 and released. It is discharged from the outlet 12 to the ship side 2 side.
[0023]
The initial flow of hot water discharge activates the flow switch 19, which activates the generator 20, activates the electric heater 21 and the pump 22, opens the electromagnetic on-off valve 23, and opens the sea chest. Seawater is sucked from 24, heated by the electric heater 21 and continuously sent to the hot water discharge pipe 11, and hot water is discharged continuously from the initial hot water discharge.
[0024]
Hot water is poured from the head of the pirate who tries to climb the rope and rope ladder by hooking the anchor. At this time, the hot water is discharged from the discharge port 12 provided vertically in the hot water discharge pipe 11, so that it is discharged as a wide hot water curtain, which is unavoidable, thereby repelling the pirates.
In addition, when an anchor is hooked in two places, hot water will be discharge | released at each place simultaneously.
[0025]
When it is confirmed that the pirate has escaped, when the anchor hooked on the trigger 6 is removed, the trigger 6 is automatically returned to the upright state by the spring 9, and the trigger rotation detection mechanism 10 is also reset by the lever 8, and the on-off valve 14 is closed.
Depending on the size (weight) of the anchor, the trigger 6 may return to the upright state by the spring 9 when the pirate releases the rope tied to the anchor.
[0026]
When the on-off valve 14 is closed, no fluid flows in the flow switch 19, so that the flow switch 19 is turned off, the start of the generator 20, the operation of the electric heater 21 and the pump 22 is stopped, and the on-off valve 23 Is also closed.
Note that these stop operations may be reset by another operation.
And the hot water is newly stored in the pressurized tank 16, and the original state is restored.
[0027]
In addition, for the purpose of inboard use on a ship, hot water is always produced with a boiler installed in the engine room, but if a large boiler can be installed and there is room for hot water production, a hot water supply main pipe is attached to the boiler. It can also be connected so that the hot water of the boiler is used for pirate fighting.
In this case, an electromagnetic opening / closing valve that is opened / closed by a rotation detection signal of the rotation detection mechanism 10 is provided in a pipeline that connects the hot water supply main pipe to the boiler.
[0028]
Although not shown, a protective means such as a protective net or a protective pipe with a small attachment interval can be provided on the outer surface of the trigger 6, that is, on the ship side. When this protective means is provided, it is possible to prevent the anchor from being caught directly on the handrail 5 from between the trigger 6 and the handrail 5.
Furthermore, when the rotation of the trigger 6 is detected, hot water can be discharged in a wider range by opening the on-off valve 14 corresponding to the trigger 6 on both sides of the rotated trigger 6.
[0029]
【The invention's effect】
The present invention can quickly detect the intrusion of a pirate who tries to climb up the rope and rope ladder by throwing the anchor and hooking it on the railing, and at the same time, it can enter the pirate intrusion zone. On the other hand, it was possible to continuously release hot water, and to obtain an effective means to repel pirates intensely and reliably.
