As shown in Figure 1, the utility model comprises buoyancy tank 1, wave absorption plate 2, mooring system; Described buoyancy tank 1 is totally enclosed hollow cavity; Described wave absorption plate 2 at regular intervals more than is connected in the bottom of buoyancy tank 1; On wave absorption plate 2, be provided with wave absorption hole 4; Wave absorption hole 4 on the adjacent wave absorption plate 2 that front and back are provided with is dislocatedly distributed, and buoyancy tank 1 is connected with mooring system, and described mooring system mainly is made up of the anchor chain 3 between the anchor that sinks to the bottom, waters and connection anchor and the buoyancy tank.Described buoyancy tank 1 is connected with anchor chain 3.One end of described anchor chain is fixed or hinge is connected on the surface at buoyancy tank top.
In order to weaken the energy of the wave of frontal impact as much as possible; The face of the heading sea arranged outside of buoyancy tank has the curved panel 8 of horizontally set; On curved panel 8, be provided with a plurality of wave absorptions hole 4, the shape in described wave absorption hole 4 can be diversified, is provided with open ports 7 at the two ends of curved panel.When the wave impact buoyancy tank, what at first impacted is the outer curved panel that is provided with of buoyancy tank, after wave passes wave absorption hole set on the curved panel, gets rid of to the open ports at curved panel two ends, thereby reaches the effect of cutting down Wave energy.
For make 1 of wave absorption plate 2 and buoyancy tank to be connected (combination) more firm; The utility model also comprises anchor post 5; One end of described anchor post 5 is fixed on buoyancy tank end face, the other end and passes the cavity of buoyancy tank, extends to wave absorption plate lower end after passing from the buoyancy tank bottom surface, and described every block of wave absorption plate 2 is fixed through many anchor posts.
In order to improve wave dissipation effect; On the wave absorption plate, also be provided with a plurality of Wave-dissipating blocks 6; Described Wave-dissipating block is for being fixed on the lip-deep variform haunched member of wave absorption plate; Wave-dissipating block 6 on the adjacent wave absorption plate 2 that front and back are provided with is dislocatedly distributed; The position of set Wave-dissipating block 6 faces the wave absorption hole 4 of last block of wave absorption plate on one the wave absorption plate in back, and the position in set wave absorption hole 4 faces the Wave-dissipating block 6 of last block of wave absorption plate on the back one wave absorption plate, and this structure is provided with and is beneficial to the energy that lets Wave-dissipating block dissolve the wave on the wave absorption plate that impacts next stage from the wave absorption hole of the wave absorption plate that passes previous stage step by step.The shape of described wave absorption plate 2 can be the plate of surface plate or wave panel or other Any shape.
In order to improve the safety in use of the utility model mole; Described mooring system can be set to fixedly mooring system 3, protection mooring system 12 and safe berth system 11; Anchor chain in the described fixedly mooring system is under the state of being straightened under normal conditions all the time; That is to say that the anchor chain in the described fixedly mooring system is bearing the tension force of heaving of the sea impact and the damage of reciprocating load Lower chains fatigue failure, when fixedly anchor chain fracture takes place or slips anchor; In order to ensure the fracture of the anchor chain in the fixing mooring system or slip behind the anchor; Can also there be the anchor chain in the mooring system that buoyancy tank is played a protective role; Therefore, the utility model is provided with the protection mooring system, and the anchor chain in the described protection mooring system is the cable-length in the mooring system fixedly; When buoyancy tank was impacted in daily heaving of the sea, the anchor chain in the protection mooring system was in lax fully state.
Described protection mooring system comprises the anchor that sinks to the bottom, waters and is connected in the anchor chain between the buoyancy tank that described buoyancy tank below is provided with many mooring systems.
In order to improve safety, described fixedly mooring system can adopt different length with the anchor chain of protection mooring system.As: can the length of chain cable of all mooring systems be arranged to two kinds of length; Wherein relatively the length of short a kind of anchor chain slightly is longer than the water surface to the water-bed degree of depth, so that the floating zone of control buoyancy tank; The length of slightly being longer than shorter anchor chain than the length of long a kind of anchor chain relatively.The same anchor chain that multiple length gradient also can be set.
Fix and protect in the mooring system anchor chain to rupture fully or slip behind the anchor in order to prevent the utility model; The floating breakwater of the utility model can arbitrarily float and drift about; And cause to building facilities waterborne and in water the boats and ships of cruising cause beyond thought destruction; On one or more walls of described buoyancy tank, be provided with one or more safety doors 10; The length that attachment security mooring system below described safety door 10, the length that is connected in the safe anchor chain in the mooring system of described safety door (10) below are connected in any anchor chain in the mooring system of described buoyancy tank below is long.Anchor chain fracture or slip anchor moment in the protection mooring system, safe anchor chain will receive huge pulling force, under the effect of pulling force, will safety door 10 be left behind, thereby make water inlet in the buoyancy tank and sink to the bottom in waters.When safety door is in closure state, for being tightly connected, guarantee that buoyancy tank is a seal chamber, helps buoyancy tank and keeps afloat between the buoyancy tank wall at the safety door and the place of being attached thereto.
In order anchor chain to be played the effect of protection, be outside equipped with anchor chain sleeve pipe 9 at anchor chain, an end of anchor chain sleeve pipe is fixed on the buoyancy tank end face.
The utility model can adopt metal, steel concrete or plastics to process.The length of the utility model floating breakwater can be set according to the needs that reality is used, length and width, and height is not limit.
The wave absorption principle of the utility model is following:
When ripple collided wave absorption plate 2, a part of bump Wave-dissipating block opposite sex member can make ripple fully broken in different angles, and breaker consumes its wave energy to diffusion all around and other ripples collisions; Partly ripple is through poroid fragmentation for another, and entering second level wave absorption plate because it is limited to pass through the wave current amount in wave absorption hole, clashes into the Wave-dissipating block opposite sex member on the wave absorption plate of the second level again; Can make ripple fully broken, again with structure upper and lower plates bump and friction, simultaneously to diffusion all around; With alternate poroid breaker collision, form vortex, the violent turbulent fluctuation of water particle again, its wave energy decays; Get into third level wave absorption plate again, and the like, wave energy is cut down step by step.
