Self-adaptive ship-intercepting method

Abstract

The invention discloses a self-adaptive ship-intercepting method. The method has the following advantages that: the method overcomes the problem that because buoys and intercepting cables can be pressed into water by ships in the past, the anti-collision intercepting facilities can fail; moreover, because buoys and intercepting nets normally horizontally float on the water surface and the lengths of the buoys and the intercepting nets do not have affection on the stability of the whole system, the lengths of both the buoys and the intercepting nets are not limited, thereby the intercepting effect is ensured, and moreover, when the intercepting system used in the method normally horizontally floats on the water surface, sight on the sea surface cannot be affected; in addition, the intercepting system used in the method has the advantages of low construction cost, high economical efficiency, long service life and convenient replacement and maintenance; and moreover, the method can be flexibly transported to different places for use, and can change the arrangement position of the intercepting system.

Description

technical field [0001] The invention relates to a ship interception method, in particular to an adaptive ship interception method. Background technique [0002] 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 hol...

[0002] 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 loses 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

[0003] 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.
