Description

Anti Pirate High Pressure Spray Nozzle {Anti-Piracy water Jet Gun}

The present invention relates to an anti-piracy high pressure injection nozzle mounted on a vessel in order to prevent the piracy of the sea rapidly increasing in recent years. More specifically, the present invention improves the problems of the conventional high pressure jet nozzle by hydraulically driving the high pressure jet nozzle mounted on the railing of the ship without an electric device, and variable injection direction, the conventional high pressure jet is fixed in the injection direction It relates to a high-pressure jet nozzle that can improve the problem of the nozzle to more effectively prevent the onboard pirates.

In recent years, armed sea robbery has been a frequent occurrence at sea off the coast of Somalia and around the world. In order to prevent this, countries around the world have cooperated and put naval service in frequent areas where pirates appeared, but it is impossible to monitor all the wide seas, and pirates are caught because they continue piracy in the gaps or areas where surveillance is neglected. It is not easy to do.

For this reason, ships in charge of logistics around the world have no choice but to bypass the pirates in a safe area without risk, or take the risk of pirates and operate the ship to the pirates' haunting area. The best way to prevent such piracy is to find ways to protect each ship on its own.

To this end, a large number of ships equipped with weapons and facilities for protecting themselves from pirates are increasing. The most basic example is to have a weapon, such as a gun, to choose to fight against armed forces when pirates appear. However, this method is not only effective in front of pirates heavily armed with the latest weapons of mass destruction, but can be reckless. In addition, it is not preferable because there is a big concern of the event.

In order to solve this problem, various facilities may be installed to prevent pirates from boarding a ship. For example, a pirate ship approaches a ship by hanging a large net around the ship when the pirate appears, and a method of causing the ship to hang on the net may be used. However, there is a problem in that the ship must always carry a large net with a bulky and heavy, and there is a problem that the effect of preventing piracy when the pirate ship does not sink in the net is insignificant.

As another example, a method of preventing pirate boarding by using a high-pressure jet nozzle may be used. In general, pirates approach the ship's exterior and attempt to board the ship using a GRAPPLING HOOK or PORTABLE LADDER. At this time, it is possible to prevent the boarding of pirates by spraying water on the outer surface of the ship by using the high-pressure jet nozzle mounted on the railing (THE RAILING). The method using the high pressure spray nozzle is superior to the method using a large net, but the conventional high pressure spray nozzle operates electronically, which requires a separate electric facility to be bulky and expensive to manufacture. heavy. In addition, there is a problem that the frequency of failure is high due to the moisture in the electrical equipment due to the nature of the mechanism for injecting water. In addition, the conventional high-pressure jet nozzle is fixed to the railing, there is a problem that can not prevent the pirates attempting to embark using a blind spot where water is not sprayed because the spraying direction of water is fixed.

In order to solve the above problems, the present invention improves the problems of the conventional high pressure injection nozzle by hydraulically driving the high pressure injection nozzle mounted on the railing of the ship without an electric device, and variably adjusts the injection direction, the injection direction An object of the present invention is to improve the problem of the fixed high pressure jet nozzle.

Referring to FIG. 3, the nozzle 150 may be configured as a pair of injection holes forming an angle of 90 degrees to each other. As the rotary shaft 140 rotates, the nozzles 150 are perpendicular to each other and may spray water to the lower portion of the hull. Assuming that water is sprayed only toward the lower part of the hull, under such a structure, the rotation angle of the rotating shaft can be limited to 90 degrees. Of course, the present invention is not limited thereto, and the number of nozzles and the angle between the nozzles may be variously selected according to the choice of those skilled in the art.
