A new surge-type high-efficiency floating breakwater that includes a buoyancy tank 1, a cross brace 2, a sprinkler 3 and a water supply hole 4, said sprinkler 3 from a water screen nozzle head 301, nozzle 302, and valve 303. It is composed. Here, the nozzle 302 is located inside the second water storage tank, the water screen nozzle head 301 and the valve 303 are located outside the upper part of the second water storage tank 8, and the number of the buoyancy tanks 1 is two. There is, and there is a fixed connection between them via a cross brace 2, the inside of the buoyancy tank 1 is divided into a first water storage tank 6, a gas compression tank 7, and a second water storage tank 8, and the water supply hole 4 is It is on the wave facing surface of the buoyancy tank 1 and is connected to the first water storage tank 6, and the bottom of the first water storage tank 6 communicates with the second water storage tank 8 via the pipeline 11 and the gas compression tank 7 is used. The lower end is open, and a one-way air inlet valve 10 and a one-way air outlet valve 5 are arranged at the upper ends of the gas compression tank 7 and the second water storage tank 8, respectively, and the one-way air inlet valve 10 and the one-way air are arranged. A conical upper cover is fixedly installed on the upper part of the outlet valve 5, a fluid one-way valve is provided between the first water storage tank 6 and the second water storage tank 8, and the flow direction of the fluid one-way valve is , The first water storage tank 6 to the second water storage tank 8, the gas compression tank 7 communicates with the second water storage tank 8 via the one-way ventilation valve 9, and the sprinkler 3 is the second water storage tank 8. At the top of.

The sprinkler 3 is composed of a water screen nozzle head 301, a nozzle 302, and a valve 303. Here, the nozzle 302 is arranged inside the second water storage tank 8, and the water screen nozzle head 301 and the valve 303 are arranged on the upper outside of the second water storage tank 8. Here, the insertion depth of the nozzle 302 into the buoyancy tank 1 is the deepest, the insertion depth of the one-way air inlet valve 10 above the gas compression tank 7 is the second, and the second water storage tank 8 is the second. The insertion depth of the one-way air outlet valve 5 at the top of the above is the shallowest, and the two buoyancy tanks (1) are fixedly connected by a plurality of cross braces (2), and the plurality of cross braces (2) are fixedly connected. The number of water supply holes (4) arranged linearly and included between any two adjacent cross braces (2) is three or more.

The cross section of the water supply hole 4 is in the shape of a horn opening that gradually decreases along the direction of the wave, and the height gradually increases. The advantage of this design is that under the action of waves and ocean currents, seawater easily enters the inside of the first water storage tank 6 through the horn-shaped water supply hole 4, and has the effect of being easy to enter and difficult to discharge.

Specifically, the buoyancy tank 1 can be divided into a wave facing buoyancy tank and a wave receiving buoyancy tank, and the two buoyancy tanks 1 have the same structure, and there are a plurality of the cross braces 2 as described above. The four corners of the buoyancy tank 1 are chamfered. The advantage of this design is that a moon pool can be formed between the buoyancy tank 1 and the cross brace 2. The moon pool effect causes the water in the moon pool to violently vibrate, helping to eliminate waves, and the moon pool effect. , The liquid level in the moon pool rises, helping seawater to enter the first water storage tank 6 through the horn-shaped water supply hole 4.

Operating principle:
First, due to the action of waves and water flow, water particles enter the first water storage tank 6 through the horn-shaped water supply hole 4, and the water in the first water storage tank 6 enters the second water storage tank 8 through the pipeline 11. Subsequently, the water in the second water storage tank 8 continues to rise, and the final liquid level is higher than the height of the nozzle 303 at the bottom of the sprinkler 3.

When the seawater level in the gas compression tank 7 moves downward with respect to the breakwater, the one-way air inlet valve 10 at the top of the gas compression tank 7 opens, and air enters the gas compression tank 7, and at this time, one-way ventilation is performed. The valve 9 is closed.

When the seawater level in the gas compression tank 7 moves upward with respect to the breakwater, the one-way air inlet valve 10 at the top of the gas compression tank 7 closes, and at this time, the one-way ventilation valve 9 opens and the gas compression tank 7 opens. The gas in the upper part of the water enters the second water storage tank 8 through the one-way ventilation valve 9.

As the air pressure in the upper part of the second water storage tank 8 gradually increases, when the pressure reaches a predetermined pressure value of the valve 303, the valve 303 opens, and under pressure, water passes through the nozzle 302 and the water screen nozzle head 301. Be sprayed. The nozzle 302 is installed on the chamfer on the rear side of the buoyancy tank body to prevent water from collecting on the upper part of the breakwater. After a certain amount of water has been sprayed, the pressure in the second water storage tank 8 drops, the water level in the cabin drops to a specific position, and then the one-way air outlet valve 5 at the top of the second water storage tank 8 It opens, exhausts from the upper air chamber of the second water storage tank 8, the seawater of the first water storage tank 6 flows into the second water storage tank 8 again, and the one-way air outlet valve 5 closes to complete the surge.
