Air-curtain breakwater

Abstract

The invention discloses an air-curtain breakwater. A water pressing pipe is arranged at two sides of a bottom of an exhaust pipe separately, and is a cylindrical hollow pipe, the two water pressing pipes are symmetrically arranged relative to exhaust holes, the water pressing pipes are as long as a pipe body of the exhaust pipe, and included angles between the center of the exhaust pipe and the centers of the two water pressing pipes are 90-120 degrees; and the pipe diameter of the exhaust pipe is 2-3 times of the pipe diameter of each water pressing pipe. According to the air-curtain breakwater disclosed by the invention, the position of the exhaust pipe can be easily placed correctly, the case of incorrect positions of the exhaust holes in the exhaust pipe is avoided, and good exhaust effect and wave absorbing effect are achieved; the exhaust pipe is capable of floating and sinking in water with the water pressing pipes, and a depth position of the exhaust pipe in water is adjustable, so that blockage of sediments at a water bottom for the exhaust holes of the exhaust pipe can be avoided, and a pressure pressed in the exhaust pipe has no need to be increased with the increase of a water depth, so that low energy consumption is achieved; and the exhaust pipe has no need to always sink to the water bottom and is free from self-sinking.

Description

technical field [0001] The invention relates to the technical field of breakwaters, in particular to an air curtain breakwater. Background technique [0002] Existing air-curtain breakwaters, for example, the application number is 201510245410.7, and the name of the invention is an air-curtain breakwater used in a method of using air-curtain breakwaters to protect the head of the embankment. A pipe with a large number of small holes on the surface and a compressor station installed on a berthing ship or an independent working ship. When the air curtain breakwater is in working condition, the compressor station generates compressed air with a certain pressure along the conduit. Or the dry pipe is transferred to the hole pipe part. The compressed air sent into the orifice tube emerges from the small hole on the tube to form a large number of air bubbles, which gradually rise and expand in the water, and form a bubble curtain along the entire length of the orifice tube.

AI Technical Summary

Problems solved by technology

[0003] But the above-mentioned existing air curtain type breakwater has the following disadvantages: the seabed topography is complex, and the position of the exhaust pipe at the bottom of the water should not be placed correctly, resulting in the incorrect position of the opening on the exhaust pipe, which will affect the air outlet effect and cause poor wave dissipation effect. ;Because the exhaust pipe is always sinking at the bottom of the water, as the water depth increases, the pressure that needs to be pressed into the exhaust pipe increases, and the energy consumption is high; the exhaust pipe sinks on the seabed for a long time, and it is prone to self-sinking phenomenon; the exhaust pipe After stopping work, the sediment at the bottom of the water is easy to block the air outlet of the exhaust pipe
