Pendulum bob type multilayer-bag type wave absorber and method

Abstract

The invention provides a pendulum bob type multilayer-bag type wave absorber and a method. The wave absorber comprises at least two layers of floating bodies and one layer of weights. For each layer of floating bodies, the multiple sections of the bag type floating bodies are connected end to end in sequence through chains to form an annular shape. The top of each bag type floating body is provided with ventilating pipes and water pipe connectors. The adjacent water pipe connectors of every two adjacent bag type floating bodies on the same layer communicate with each other through a flexible water pipe. The floating bodies on the adjacent layers are connected through chains. The floating bodies on the lowermost layer are connected with the weights through chains. According to the pendulum bob type multilayer-bag type wave absorber and the method provided by the invention, the two layers or multiple layers of floating bodies are adopted, and wave diffraction is stopped by increasing the vertical height of the wave absorber, so that wave reflection is generated; then wave energy is absorbed through swinging of the bags on the lower portion and the weights, and accordingly a wave absorbing effect is achieved; and the two-layer or multilayer-bag type wave absorber can effectively stop short waves and long waves, and is suitable for being used for wave absorbing of building and construction work of ocean engineering.

Description

technical field [0001] The invention belongs to the field of marine engineering, and in particular relates to a pendulum-type multi-layer capsule wave-eliminating device and method. Background technique [0002] The construction of marine engineering and its normal operation have high requirements on the wave environment load, and it is expected to obtain a marine environment with a small wave height. The gravity-fixed breakwater is a more common anti-wave facility, but it has great limitations because it cannot move quickly. The floating anti-wave is easy to move and assemble, and can be used repeatedly. It is widely used in the construction of marine engineering projects. The current floating anti-wave system is mainly a single-layer anti-wave device. Yes, but the transmittance is still high for long waves that diffract from the bottom of the breakwater into the protected area.

Gravity-fixed breakwater is a common anti-wave facility, but it has great limitations because it cannot move quickly

The floating anti-wave is easy to move and assemble, and can be used repeatedly. It is widely used in the construction of marine engineering projects. The current floating anti-wave system is mainly a single-layer anti-wave device. Yes, but the transmittance is still high for long waves that diffract from the bottom of the breakwater into the protection zone
