Description
Technical field
The present invention relates to navigation safety technical field, especially a kind of inland river bridge collision avoidance system.
Background technique
In recent years, vessel underway oceangoing ship amount, built and continue in the quantity of bridge construction beam with the development in an all-round way of China's economic situation
Increase, bridge collision dangerous situation occurs again and again.It is well known that bridge is for improving public affairs, iron, road traffic efficiency have it is very important
Meaning, but bridge is for water transport traffic, especially inland river navigation, is that cannot be neglected river barrier.Due to depositing for bridge
There is certain limitation to height, the route speed etc. of inland navigation vessel, is bringing security risk to navigating ship.With
This simultaneously, the overload of China's inland navigation craft, superelevation, overrun issues are also difficult to always solve, this further increase bridge collision
The harmfulness of accident brings safely huge security risk to water transportation.
In March, 2014, at Yangzhou Baoying County, the waters river deer lion Dong Qiao, the river Bao She, the wheel of " red flag drags 369 " fleet one 11 is dragged, unloaded
Bridge accident to be hit when uplink, bridge floor paralysis is caused to collapse, and is pressed in fleet's tail third gear ship stern ceiling, is caused Calculation of Ship Grounding's, navigation channel is stopped navigation,
Without personnel death.
In September, 2014, " mound boat drags 699 " (fleet, a wheel 11 belonging to He Hai transportation company limited, Yancheng of Jiangsu Province Funing County
Drag, load stone) Yancheng is sailed for by Huaiyin, bridge waters is penetrated on Tongyu river Jianhu County ridge, fleet's affiliated rowing boat touching ridge is penetrated
Bridge, the overboard death of 1 people on ship.
In December, 2014, " dragging 2049 in Jiangsu " belonging to shipping company, Jiangsu Xiuqian City, (fleet, a wheel ten drag, and load cement
5000 tons of clinker), from Shandong, Tai Erzhuan sails for East China, and at the lock upstream about 1Km of the Xinhe River Huai Shu Shuyang, fleet and item swing bridge
Collision causes item to swing bridge main span bridge collapse, first shelves barge sinking.
The report of Yancheng City Local maritime office is connect at 2 months 2017, Chuanchanghe River (seven grades of boats in the Yancheng City Jianhu County town Cao Yan
Road) 233 bridge Its Adjacent Waters, " Soviet Union's Yancheng machine 99159 " (gross ton 300) dry cargo ship belonging to Heng Lin logistics Co., Ltd, Funing County is unloaded
A bridge block on Chuanchanghe River is knocked from north orientation south, causes driver's cabin to be squeezed and causes 2 people dead.
When in October, 2017, " Henan Far Glory 106 " single machine ship comes downwards at 200 meters of Huaihe River Bridge Downstream and collides Huaihe River bridge
Right side main pier leads to hull damage water inlet sinking.It is touched during " Su Huahang 6058 " (2000 gross ton yellow sand) single machine ship downlink
Main pier on the left of the bridge of Huaihe River is bumped against, since Huaihe River flood discharge causes Huaihe River main channel water flow larger, accident ship is stranded Main Bridge
Bridge pier waters.
In November, 2017, one loading about 1000 tons of stones steel ship (no card, 48 meters of captain, 8.8 meters of the beam, moldeed depth
3.75 meters) when travelled from south to north to such as freeway bridge southern side sea canal Rugao Xue kiln Duan Ningtong, which touches
East navigable west side bridge pier causes the ship to sink, and 1 people is missing on ship.
In order to preferably ensure navigation safety, navigation order in maintenance bridge waters protects bridge and shippping traffic (packet
Include floating facility) safety, water pollution is prevented, domestic multiple provinces have intended carrying out ship bridge collision avoidance system Pilot project construction work
Make, realizes to the comprehensive management of bridge zone vessel underway oceangoing ship, prevent bridge collision accident.
Conventional method bridge anticollision status:
Traditional bridge anti-collision device is divided into active crash-proof and passive crash-proof.Active anti-collision facility is by increasing navigable
Width and construction increase channel span without beam bridge pier etc..The design concept of passive anti-collision facility is then by changing ship
Crash direction and the size for reducing impact force limit or prevent ship from the modes such as directly impinging on bridge pier or bridge.
According to the difference of ship crash energy absorption process and setting place, using another classification method, various modes
Anti-collision facility it is as follows.
(1) it directly constructs,
Flexible deformation type: fender mode, rope mode；
Compression set type: buffer body mode；
Displacement type: gravity type.
(2) indirect configuration,
Flexible deformation type: stake mode；
Compression set type: caisson type, man-made island mode；
Displacement type: floating body mooring line mode.
Following three classes are simply summarized as by automatic collsion avoidance system:
1) integral type anti-collision system
2) adhesion type anti-collision system
3) free-standing anti-collision system
It is the Some features of these different anti-collision facilities below.
The classification of bridge anticollision device, collision-prevention device and feature
Bridge anticollision technical aspect is primarily present following problems at present:
Traditional anticollision technology mainly passes through reconstruction bridge and reduces the impact force that ship pushes away bridge, to realize reduction ship
Oceangoing ship hits the influence to bridge to bridge.For such technology without fundamentally solving bridge collision problem, accumulating over a long period can be to bridge
Beam generates imponderable influence.
Setting crash bearer can connect in front of bridge pier to avoid ship straight hits bridge pier, but only solves bridge security and ask
Topic, not can solve the safety problem of ship but, this is not inconsistent with the objective for guaranteeing safety of traffic on water.
The existing active anti-collision early warning system based on informationization, although the hair that ship hits bridge event can be effectively prevented
It is raw, but this system is only applicable to the broad navigation channel Hai Jiang of the water surface, the cruiseway narrow for navigation channel cannot play its function
It can.
Summary of the invention
In order to overcome the problems referred above, the object of the present invention is to provide a kind of inland river bridge collision avoidance system, realize that ship is passed a bridge
