Jet flow and bubble breakwater capable of automatically adjusting flow direction and wave elimination method thereof

Abstract

The invention provides a jet flow and bubble breakwater capable of automatically adjusting the flow direction and a wave elimination method thereof. The jet flow and bubble breakwater capable of automatically adjusting the flow direction comprises a plurality of breakwater units, the jet flow and bubble breakwater capable of automatically adjusting the flow direction and the wave elimination method thereof can automatically adjust the direction angle of a jet nozzle and the working depth of an air jet device, the breakwater is convenient and fast to lay, and the needs for emergency rescue anddisaster relief and military operations are met. The breakwater is laid under the water surface and provides a good navigable view for the passage of a ship, the normal passage of the ship can be guaranteed after the breakwater stops working, and the problems that a traditional floating breakwater impedes navigation or increases navigation time are solved. By the design of the air jet device and ajet device, flexible use can be achieved, and different functions are achieved; the position of the air jet device can be adjusted by adjusting the water-air ratio of a ballast bin and a gas bin, thewave resistance effect is improved, and the problem that an existing exhaust pipe is high in energy consumption and prone to being buried is solved; and the jet flow direction can be adjusted automatically through a jet regulator, and automatic work is achieved under unattended conditions, so that the labor cost is reduced.

Description

technical field [0001] The invention relates to the field of breakwaters, in particular to a jet and bubble breakwater for automatically adjusting the flow direction and a wave elimination method thereof. Background technique [0002] The breakwater is a hydraulic structure required to defend against wave intrusion and form a sheltered water area. It is located on the periphery of the port water area to ensure that the port has sufficient water depth and stable water surface to meet the requirements of ships berthing in the port, loading and unloading operations, and entering and exiting navigation. The air curtain breakwater is produced by the compressor station with a certain pressure of compressed air sent to the seabed exhaust pipe, the small hole of the exhaust pipe is exhausted, and the air curtain is formed during the rising process of the bubbles, forming a surface horizontal flow in the water, making the waves wave energy attenuation, resulting in a decrease in wave...

AI Technical Summary

Problems solved by technology

[0005] However, the existing air curtain breakwaters generally have the following disadvantages: one is that the exhaust pipe is always sunk in the bottom of the water, and as the water depth increases, the pressure that needs to be pressed into the exhaust pipe increases, and the energy consumption is high; the other is that The exhaust pipe has sunk on the seabed for a long time, and the sediment on the seabed is transported by the water flow, so that the exhaust pipe laid on the seabed is gradually buried during operation; the third is that after the exhaust pipe stops working, the sediment on the bottom of the water It is easy to block the air outlet of the exhaust pipe; fourth, due to time and natural environment constraints in emergency rescue or military operations, traditional floating breakwaters have problems such as hindering navigation or increasing navigation time; third, the jet flow direction of traditional jet jet breakwaters Fixed, although the flow speed can be adjusted according to the incoming wave data, but the wave dissipation effect cannot be improved by changing the incoming wave direction
