Abstract
A floating foundation overhead ship arresting facility with reliable dragging energy dissipation is composed of floating foundations, supporting frames, an arresting net, an anchorage system, a sinker trigger mechanism and the like. Main gravity anchors for dragging energy dissipation are hung below the floating foundations, main anchor chains are restrained through the sinker trigger mechanism, the main gravity anchors are made to leave a silt surface in a high water level state, and therefore the phenomenon that the main gravity anchors sink into silt and cannot be dragged can be prevented. When a ship collides with the arresting net, the main anchor chains are not restrained, the main gravity anchors can be dragged for energy dissipation, and eventually the ship is prevented from moving towards a bridge location. Even though part of the arresting net acts on a bow, the transversely-rotating angle of the arrested ship and motion after transverse rotating of the ship is blocked are limited through the multiple floating foundations together, and arresting failures caused when the arrested ship transversely rotates can not occur. The floating foundations are used for supporting the arresting net, and the floating foundation overhead ship blocking facility can well adapt to variation of the water level, and be used in an abyssal region and used for transition and any extension. The floating foundations deviate under direct collision of the ship, and therefore the arresting facility cannot break down.
Description
Technical field
The present invention relates to a kind of ship's repairs & maintenance facilities that blocks of protecting non-navigation bridge section.
Background technology
At present, the anti-ship collision facility of known bridge, mainly contains two classes.
One class is arranged on bridge pier, utilizes the distortion of fender system, absorbs boats and ships kinetic energy, extends the effect of impact time, thereby reduces ship impact force.This type of fender system skill level complexity, construction and installation expense is higher.For non-navigation bridge section, under bridge, clear height is limited conventionally, need to protect bridge pier and superstructure simultaneously, and this type of facility is difficult to play a role.
Another kind ofly be arranged on non-navigation bridge section and come outside the certain distance of shipboard, utilize the resistance that drags of anchor of gravity anchor to do negative work or utilize the elastic-plastic deformation of cable body material to consume the kinetic energy of boats and ships, the final boats and ships that stop move to bridge location, conventionally have overhead fixed, mooring floating, mooring and fix hybrid.For overhead fixed and hybrid, its pile foundation support table does not possess the ability of bearing the direct shock of large ship conventionally, if directly clashed into, may cause blocking unsuccessfully.For mooring formula and hybrid, in the process of blocking, boats and ships can horizontally turn, and the suffered lateral current power of boats and ships after horizontal turning is much larger than its suffered longitudinal drag force, increase the counter-force of blocking facility and carry out the suffered lateral current power of balance boats and ships if relied on, the construction and installation expense that can cause equally blocking ship's repairs & maintenance facilities is high.Do negative work and consume the ship's repairs & maintenance facilities that blocks of boats and ships kinetic energy for the resistance that drags of anchor that utilizes gravity anchor, will face gravity anchor by the silt of nuzzling and the risk that cannot drag of anchor.
Summary of the invention
Guaranteeing to block under the prerequisite of effect, for reduce block the construction and installation expense of ship's repairs & maintenance facilities and hit by ship after restoration costs, adapt to better SEA LEVEL VARIATION and work in profundal zone, eliminate gravity anchor by the silt of nuzzling and the risk that cannot drag of anchor, the invention provides the one overhead ship's repairs & maintenance facilities that blocks of the reliable floating foundation of energy dissipating that drags of anchor.
The technical solution adopted for the present invention to solve the technical problems is:
The overhead ship's repairs & maintenance facilities that blocks of the reliable floating foundation of the energy dissipating that drags of anchor is made up of floating foundation, bracing frame, arresting net, main gravity anchor, Bower Anchor chain, piggy-back anchor, auxiliary anchor cable, sinker trigger mechanism and sinker triggering rope etc.Several floating foundation keep at a certain distance away and are arranged in a straight line or broken line, by piggy-back anchor and auxiliary anchor cable anchorage.Bracing frame is arranged on floating foundation, is used for supporting arresting net.Utilize Bower Anchor chain main gravity anchor to be hung on to the below of floating foundation, at least guarantee that main gravity anchor can leave mud face in the time of high water level, or utilize high water mark to leave mud face by the main gravity anchor of floating foundation automatic lifting, can avoid main gravity anchor to be embedded in silt and the rough sledding that cannot drag of anchor occurs.For main gravity anchor can sink to mud face when the ship collision, sinker trigger mechanism is set on floating foundation, and sinker is triggered to the auxiliary anchor cable that rope connects arrival shipboard.For the ease of arranging, single larger main gravity anchor can be designed to multiple less main gravity anchors, thereby be convenient to be suspended on floating foundation below.
In the time of ship collision arresting net, to drive floating foundation to move to bridge location, the auxiliary anchor cable, the piggy-back anchor that are positioned at shipboard will first be subject to active force, when this active force increases to after certain value, be applied to sinker trigger mechanism by triggering rope, discharge Bower Anchor chain, continue to the process of bridge location motion at boats and ships, to drive main gravity anchor to drag of anchor to consume boats and ships kinetic energy by arresting net and floating foundation, and finally stop boats and ships to move to bridge location.
In order to prevent from being blocked, boats and ships are horizontal causes blocking inefficacy after turning, and jointly limit the horizontal gyration of boats and ships and stop that boats and ships are horizontal motion after turning by crossing multiple floating foundation.In the time that floating foundation is directly clashed into by boats and ships, will partially allow, thereby boats and ships are finally applied on arresting net.
The invention has the beneficial effects as follows:
Main gravity anchor leaves mud face or in the time of high water level, leaves mud face, can prevent from cannot dragging of anchor because of Sediment Siltation; Though there is part arresting net to act on bow, jointly limit the horizontal gyration of boats and ships and stop that boats and ships are horizontal motion after turning by multiple floating foundation, can be because being blocked the horizontal of boats and ships then cause blocking unsuccessfully; Adopt floating foundation support arresting net, can adapt to preferably SEA LEVEL VARIATION and use in profundal zone, be convenient to block facility transition and use and spreading use arbitrarily; When boats and ships directly clash into floating foundation, the floating foundation after stressed will allow partially, and boats and ships are finally applied on arresting net, therefore in facility, not have weak joint portion blocking.

The specific embodiment
In Fig. 1 and in Fig. 2, floating foundation (1) is by piggy-back anchor (4), auxiliary anchor cable (5) anchorage.Main gravity anchor (2) is suspended on the below of floating foundation (1) by Bower Anchor chain (3).Bracing frame (8) is arranged on floating foundation (1) top, is used for supporting arresting net (10) and reaches design height.Arresting net (10) is made up of main check cable (11), auxiliary check cable (12), connecting strand (13).Main check cable (11) is generally the check cable of the top in arresting net (10), and the check cable that all the other horizontal directions arrange is auxiliary check cable (12).The vertical rope arranging is connecting strand (13).Main check cable (11) and auxiliary check cable (12) are connected on Bower Anchor chain (3) directly or indirectly.In the time blocking spitkit, main auxiliary check cable (12), the connecting strand (13) of relying on plays a role; In the time blocking large ship, main check cable (11), auxiliary check cable (12), connecting strand (13) play a role jointly.For reducing the deadweight of arresting net (10) and suffered wind active force, the bearing capacity of main check cable (11) is often greater than the bearing capacity of auxiliary check cable (12), the grid of arresting net (10) is can top large, below is little, and concrete size needs to determine according to the size of blocking boats and ships.Floating foundation (1) can be monomer, binary or multiple hull construction, if adopt the floating foundation (1) of binary or multiple hull construction, need guide ring (14) be set at the shipboard that comes of floating foundation (1).In the time that boats and ships directly clash into floating foundation (1), will first bump against the side of guide ring (14) or floating foundation (1), promote floating foundation (1) and partially allow, final boats and ships are applied on arresting net (10).When ship collision arresting net (10), to drive floating foundation (1) motion by arresting net (10), due to the constraint of shipboard piggy-back anchor (4) of being arrived, carrying out auxiliary anchor cable (5) tension force of shipboard will increase, and pull sinker to trigger rope (9), discharge Bower Anchor chain (3), thereby main gravity anchor (2) can consume boats and ships kinetic energy by the mode of dragging of anchor, and finally stops boats and ships to move to bridge location.
In Fig. 3, in the time of boats and ships longitudinal impact arresting net (10), the floating foundation (1) of impingement position both sides can be blocked boats and ships near quilt, thereby has limited the horizontal gyration that is blocked boats and ships, has reduced drag force horizontal because of boats and ships then that increase.For large ship, because its kinetic energy is large, the distance that drags of anchor of main gravity anchor (2), floating foundation (1) can block boats and ships by more close quilt, and the horizontal gyration that is blocked boats and ships is less, and the amplitude that drag force increases is also corresponding little.For spitkit, because its kinetic energy is little, the distance that drags of anchor of main gravity anchor (2) is shorter, floating foundation (1) to the distance of being blocked boats and ships can be relatively large, being blocked the horizontal gyration of boats and ships also can be more greatly, but because the horizontal current obstruction area of spitkit is relatively less, suffered lateral current power is also corresponding little, blocks facility enough counter-forces can be provided.
In Fig. 4, in the time of boats and ships Transverse Impact arresting net (10), being blocked boats and ships is subject to larger lateral current power effect, the distance that drags of anchor of main gravity anchor (2) will be larger, the kinetic energy and the lateral current power institute work that have consumed boats and ships on the one hand, stop lateral drift boats and ships jointly by multiple floating foundation (1) on the other hand.In order more effectively to block lateral drift boats and ships, part is designed longly for the auxiliary anchor cable (5) of bridge location side, utilize the inhomogeneous feature of resistance to change the lateral drift attitude of boats and ships.
In Fig. 5, sinker trigger mechanism is made up of spacer pin (6), mount pad (7) etc., and sinker triggers one end connection spacer pin (6) of rope (9), the auxiliary anchor cable (5) that the other end connects to come shipboard.Mount pad (7) is fixed on floating foundation (1).When auxiliary anchor cable (5) tension force that carrys out shipboard increases to after certain value, to pull sinker to trigger rope (9), pull-out spacer pin (6), discharge Bower Anchor chain (3), thereby main gravity anchor (2) can consume boats and ships kinetic energy by the mode of dragging of anchor, and finally stops boats and ships to move to bridge location.
