Description

Adaptive ship interception method

technical field

The invention relates to a ship interception method, in particular to an adaptive ship interception method.

Background technique

Ship collision has become a common occurrence in the rapid development of the shipping industry today. Especially since the late 1980s, large bridges spanning large rivers, rivers, bays and connecting islands have begun to increase. The navigation holes of these bridges are generally located on customary waterways, and Generally, the main pier of the navigable hole is equipped with an anti-ship collision energy-absorbing protection system, but the project line that needs to be fortified for the non-navigable hole is long. Once the ship is out of control or human error, it is very likely to hit the non-navigation hole bridge, causing heavy economic losses and casualties. Therefore, it is necessary to set up an interception system on the outer waters of the bridge to prevent the ship from hitting the non-navigation hole bridge.

The application date is April 3, 2006, and the Chinese utility model patent specification with the patent number ZL200620025697.9 discloses an anti-collision interception facility for non-navigation piers of the Waihai Bridge. It is a continuous structure with multiple sets of steel cluster piles It is arranged at intervals with the buoy body and is integrated by a floating chain; the floating chain includes three parts: the interception cable, the buoy suspended on the interception cable, and the spring damper installed at both ends of the interception cable; the spring damper at the end of the interception cable The device is connected to the steel cluster pile inserted into the seabed and the buoy body floating on the water surface; the buoy body is connected horizontally with the spring damper at the end of the interception cable, and it is connected vertically with the anchor chain, and the other end of the anchor chain is connected with the concrete anchorage Connected; this method mainly uses the tensioned floating chain between the buoys to block the collision ship, and uses the restoring force generated by the buoys from the equilibrium state to being pulled, and the friction force generated when the seabed of the anchor chain moves when the bottom of the sea settles, etc. to absorb However, in the case of small and medium-sized ships without a bulbous bow and when the bulbous bow of a large ship is out of the water during ballast navigation, when the ship hits the anti-collision interception facility, the buoy and the interception cable are likely to slide to the lower part of the bow, resulting in anti-collision interception. If the facility fails, if in order to improve the interception effect, the height of the floating buoy is increased to increase the entire interception height, which will cause the entire anti-collision interception facility to be unstable when it is not impacted.

Contents of the invention

The technical problem to be solved by the present invention is to provide an adaptive ship interception method that can increase the interception length according to the hull height of the ship while ensuring the stability of the entire system without affecting the sea surface vision.

The technical solution adopted by the present invention to solve the above-mentioned technical problems is: an adaptive ship interception method, comprising the following steps:

(1) At least two mooring buoys at a certain distance are arranged on the water surface, and the mooring anchorage system submerged in the water is connected in different directions of the mooring buoys;

(2) Select a number of buoys whose length is greater than or equal to the height of the bow or bulbous bow, and then place these buoys at certain intervals between the mooring buoys in a manner that floats horizontally on the water surface, so that the buoys of the buoys The center is biased towards the bow end of the buoy;

(3), horizontally expand the interception net and fix it on the buoy, so that the edges of the two ends of the interception net are flush with the ends of the buoy respectively;

(4) Connect the mooring buoy and the buoy close to the mooring buoy with connecting cables.

The end of the buoy used facing the bridge is tilted up, so that the end of the interception net closest to the bridge is higher than other parts. When the interception net is erected, this end will be closer to the bow, so that it can be hung on the bow. , to further ensure the interception effect.

The material of the interception net and the connecting cable used is a high-strength nylon rope or steel cable resistant to seawater corrosion.

The mooring anchorage system used consists of anchor chains, gravity anchors and sinkers.

Multiple connecting cables are used to connect the buoy and the mooring buoy, and the length of the connecting cable between the buoy near the bridge and the mooring buoy is greater than the length of the connecting cable between the buoy near the bow and the mooring buoy, ensuring When the end of the buoy toward the bow is pulled to make the whole buoy stand up, it can smoothly drive the whole intercepting net between the mooring buoys to stand up.

Compared with the prior art, the advantage of the present invention is that the method overcomes the problem that the buoys and interception cables are pushed into the water by the ship in the past and cause the failure of the anti-collision interception facilities; The length of the buoy and the length of the interception net have no influence on the stability of the whole system, so the length of the buoy and the interception net is not limited, thereby ensuring the interception effect, and the interception system used in this method usually floats horizontally on the water surface It will not affect the vision of the sea surface; in addition, the interception system used in this method is low in cost, good in economy, long in service life, easy to replace and maintain; moreover, it can be used flexibly, and the setting of the interception system can be changed according to actual needs Location.

Detailed ways

The present invention will be described in further detail below in conjunction with the accompanying drawings.

An adaptive ship interception method comprising the following steps:

(1), place a plurality of mooring buoys 1 at a certain distance on the water surface, and connect anchor chains 7 that sink into the water in different directions of the mooring buoys 1, connect sinkers 8 on the anchor chains 7, and Connect the gravity anchor 9 at the end of the anchor chain 7;

(2), select a plurality of buoys 2 with a length (L) greater than or equal to the height (H) of the bow 5, and the buoys 2 are tilted upward toward the end 22 of the bridge, and then these buoys 2 are floated on the water surface at certain intervals and horizontally Place it between the mooring buoys 1 in the above way, and make the center of buoyancy of the buoy 2 bias toward the end 21 of the buoy 2 facing the bow 5;

(3), the intercepting net 3 is horizontally deployed and fixedly connected to the buoy 2, so that the edges at both ends of the intercepting net 3 are respectively flush with the ends at the two ends of the buoy;

(4), use multiple connecting cables 6 to connect the mooring buoy 1 and the buoy 2 close to the mooring buoy 1, and the length of the connecting cable between the buoy 2 near the bridge side and the mooring buoy 1 is greater than that near the bow 5 The length of the connecting cable between the side buoy 2 and the mooring buoy 1.

The interception process of this interception method is as follows:

There are two situations in which this interception method intercepts incoming ships and hits them:

Situation 1: When the bow 5 of the ship hits the interception system used in this method, the bow 5 first pushes the outermost edge of the interception net 3, and the outer end edge of the interception net 3 does not slide down along the hull to block the ship. And move together with the ship, then the intercepting net 3 pulls the adjacent buoy 2, drives the buoy 2 and the anchor chain 7 to move together, under the tension of the anchor chain 7, the sinker 8 will move on the bottom of the water, and the gravity anchor 9 will anchor, so that Consume the kinetic energy of the ship, reduce the speed of the ship, and finally realize the effective arrest of the incoming ship.

Situation 2: When the bow 5 of the ship hits the interception system used in this method, the bow 5 first pushes the outermost edge of the interception net 3, and under the action of the collision force of the ship, the outer end edge of the interception net 3 moves along the direction of the hull. Sliding down, the bow 5 gradually presses the outer edge of the intercepting net 3 into the water, and as the outer edge of the intercepting net 3 sinks to the lower part of the bow, it drives the end 21 of the buoy 2 towards the bow 5 to sink. One end 22 of the lower buoy 2 towards the bridge rises, thereby pulling the entire intercepting net 3 to erect from a horizontal state and to wrap around the bow of the ship or the bulbous bow of a large ship, thereby blocking the ship and moving with it, and then intercepting The net 3 pulls the adjacent buoy 2, and drives the buoy 2 and the anchor chain 7 to move together. Under the tension of the anchor chain 7, the sinker 8 will move on the bottom of the water, and the gravity anchor 9 will move the anchor, thereby consuming the kinetic energy of the ship and reducing the ship's weight. speed, and finally realize the effective arrest of the incoming ship.

In the above-described embodiment, the material of the intercepting net and the connecting cable is a high-strength nylon rope or steel cable resistant to seawater corrosion, and the number of the connecting cable can also be one; when the ship has a bulbous bow, the length L of the buoy 2 only needs to be greater than Equal to the height of the bulbous bow.

The self-adaptive performance of the method is that the intercepting net can be erected and deployed automatically from a horizontal state, and the intercepting net can enclose the bow of a ship or the bulbous bow of a large ship, thereby blocking the ship.
