An anti-climbing hydraulic striking device for ships

Abstract

The invention discloses a climbing-preventing hydraulic striking device for ships. The climbing-preventing hydraulic striking device comprises a fire pump, a water distributor, a plurality of electric control valves, fire water hoses and a plurality of hydraulic striking cannons, wherein the fire pump pumps high-pressure water to the water distributor, the high-pressure water is respectively delivered to the hydraulic striking cannons through the fire water hoses in various branches, and each hydraulic striking cannon comprises a casing with a quick fire joint, an impeller is arranged in the casing, one end of a rotary shaft of the impeller is provided with inner magnetic steel, outer magnetic steel sleeves the inner magnetic steel, a speed reduction mechanism is arranged above the outer magnetic steel and comprises a first gear, a second gear, a fourth gear, a fifth gear, a first bevel gear and a second bevel gear, the first gear rotates synchronously as the outer magnetic steel, the second bevel gear is fixedly mounted at one end of a crankshaft, the crankshaft is connected with a connecting rod, the lower end of the connecting rod is connected with a rack, and the third gear drives a swing shaft connected with a nozzle through a key. The climbing-preventing hydraulic striking device adopts the high-energy hydraulic striking cannons which are higher in striking force than conventional fire-fighting lances, is large in striking range, long in shooting distance and capable of effectively preventing climbing of terrorists, is simplified and easy to operate and maintain.

Description

technical field [0001] The invention relates to the field of ship security and is applied to ship security devices, in particular to an anti-climbing hydraulic striking device for ships. Background technique [0002] In recent years, around 80% of global trade has been carried by merchant ships. With the rapid development of the world's shipping industry, pirates and terrorists around the world have armed hijacked ships more frequently and obtained huge ransoms. Attacks on these shipping routes, especially blockades, have seriously endangered global trade, and at the same time brought heavy blows to countless families, and brought huge economic losses to shipping companies and countries. Therefore, at present, ships sailing in dangerous sea areas mainly rely on the escort of naval warships of various countries, and the cost is huge. [0003] At present, pirates or terrorists mainly approach ships by speedboats, and use ropes with hooks to hook the railings on the side of t...

Attacks on these shipping routes, especially blockades, have seriously endangered global trade, and at the same time brought heavy blows to countless families, and brought huge economic losses to shipping companies and countries

Therefore, at present, ships sailing in dangerous sea areas mainly rely on the escort of naval warships of various countries, and the cost is huge

[0003] At present, pirates or terrorists mainly approach ships by speedboats, and use ropes with hooks to hook the railings on the side of the ship to climb to the upper deck. Molecules fight at close range, the personal safety of the crew is not guaranteed, and the counterattack effect is poor, basically unable to prevent pirates or terrorists from forcibly boarding the ship
