Abstract

The invention discloses a fence type ship anti-piracy system which mainly comprises rotating devices, connectors, mooring ropes and anchor cable machines. When a ship passes through a piracy zone, the rotating devices are connected with the mooring ropes by rotating rings and distributed at sea surface by a front anchor cable machine and a rear anchor cable machine. Under the driving of the ship, the rotating devices move relative to seawater and generate rotation under action of fluid power, paddles underwater generate lateral unbalance force to drive the rotating devices to move towards an outboard direction to drive the mooring ropes to spread for forming a protective fence used for blocking and attacking pirate ships.

Description

Fence formula boats and ships pirate preventing system

Technical field:

The present invention relates to a kind of hydrokinetic fence formula pirate preventing system that utilizes, can be used for the defence of ocean range vessel the pirate.

Technical background:

The pirate is movable rampant in recent years, brings grave danger for global shipping and fishery.Present known pirate's defense mechanism can be divided two kinds, and naval escorts anti-certainly with boats and ships.Naval escorts and has protected the safety of various countries' merchant ships within the specific limits greatly; but also have following shortcoming: escorting is limited in scope; present multinational warship concentrates on Yemen south Arabian Sea and the Gulf of Aden mostly near the estuario of Red sea; but extend to the marine site, Seychelles southwards from above-mentioned marine site from 09 year Somalia pirate's action radius; make convoy naval beyond one's ability to help; in addition; the south China sea; no warship convoy zone such as the Strait of Malacca also is the movable multiple district of pirate, and Gulf of Guinea, West Africa pirate is also rampant once again.Naval escorts also to exist to be needed to wait for and forms into columns, and low steaming etc. influences the shortcoming at sailing date during escorting.Boats and ships are more single in the anti-certainly means of usefulness at present, and the self-control Molotov cocktail utilizes ship's fire fighting system high pressure hydraulic giant etc., and is passive passive, can not guarantee crewman's inherently safe.Present disclosed patent pirate preventing system exists more to be installed complicatedly, relates to the transformation to hull structure, needs the shortcomings such as authentication by boats and ships place classification society, and perishable in the environment at sea, not easy care.

Summary of the invention:

The present invention is in order to solve the problem that pirate ship is kidnapped boats and ships near ship side easily; a kind of hydrokinetic fence formula pirate preventing system that utilizes is provided, can around boats and ships, forms one deck back up ring, effectively stop the close of pirate ship; climbing is protected boats and ships.

The present invention takes following technical scheme: use a kind of water surface turning gear; utilize adaptor union on hawser; cloth is put in the sea during through the pirate zone of action; turning gear drives hawser and opens under hydrokinetic effect; both sides form fence on the quarter; stop pirate ship near boats and ships, and it is constituted bump, protection boats and ships and safety of crew.

The invention has the beneficial effects as follows: 1 installs simply, need not to change hull structure, need not boats and ships place classification society and authenticates, and does not produce Loss for Detention.2 is easy to operate, utilizes boats and ships to have equipment by oneself, and cost is low.3 have carried out similar experiment at indivedual ocean range vessels, respond well.

Description of drawings:

Below in conjunction with accompanying drawing, structure and embodiment by turning gear set forth the specific embodiment.

With reference to accompanying drawing 1, turning gear is rubber or hard plastic composite structural element, by blade (Fig. 1-1), and frusto-conical barrel (Fig. 1-2), and link flange (Fig. 1-3) is formed.During use this turning gear connection cable cloth is put in the larboard water surface; under the drive of speed of the ship in meters per second; turning gear produces relative velocity in seawater; in hydrokinetic effect turning down; because turning gear is bubbled through the water column, the blade motion of lower apron produces a side direction out-of-balance force, under this power effect; turning gear direction motion outboard drives hawser and opens formation circular arc type back up ring.

Accompanying drawing 2 is the opposite turning gear front elevation of blade direction of tilt, is used for laying of right side ship side.

With reference to accompanying drawing 3 embodiment; the present invention realizes that the technical scheme of above-mentioned purpose is: when boats and ships process pirate zone of action; turning gear (Fig. 3-3) is applied on the hawser (Fig. 3-5) by swivel eye (Fig. 3-4); and with the front and back end of hawser by stem stern chock (Fig. 3-7); lead cable wheel (Fig. 3-1) and be connected in front and back cable machine (Fig. 3-2); start the cable machine; two hawsers lay to the water surface about making; for increasing effect; also can take turns (Fig. 3-1) at cable and be connected in front and back cable machine (Fig. 3-2); start the cable machine, two hawsers lay to the water surface about making, for increasing effect; the etcetera of similar containment boom also can be set on hawser; turning gear opens hawser, forms the back up ring at boats and ships two sides of a ship, stops pirate ship near boats and ships.

The hawser of two sides of a ship forms the circular arc type fence, stops pirate ship near boats and ships.The picaroon ship when the hawser because and the velocity contrast between the big ship, pirate ship can be subjected to the bump of turning gear, makes it can not be close.This device can effectively be protected horizontal and two side of a ship positions in the boats and ships, herein also just pirate ship near the position commonly used of boats and ships.The stem stern is because the tumblehome angle is big, and it is close to exist factor such as screw propeller turbulent flow that pirate ship is difficult for.Even pirate ship attempt from the stem stern near the boats and ships industry can adopt the speed change navigation and the word sailing boats and ships are broken away to this system protection scope.

Accompanying drawing 4 is implementation result figure.

Claims

1. fence formula boats and ships pirate preventing system, be installed on the boats and ships and use, it is characterized in that: a kind of turning gear (Fig. 3-3) is applied on the hawser (Fig. 3-5) by swivel eye (Fig. 3-4), and with the front and back end of hawser by stem stern chock (Fig. 3-7), lead cable wheel (Fig. 3-1) be connected in before and after cable machine (Fig. 3-2).

2. pirate preventing system according to claim 1 is characterized in that: turning gear (Fig. 3-3) changes the size and the number of blade according to the dimension of ship difference.

3. pirate preventing system according to claim 1 is characterized in that: on the hawser (Fig. 3-5) floating debris is set, increases protection effect.
