Semicircular breakwater integrated with oscillating water column type wave energy power generation device and unit of semicircular breakwater

Abstract

The invention belongs to the technical field of coastal engineering structures, and particularly relates to a semicircular breakwater unit integrated with an oscillating water column type wave energy power generation device and a breakwater composed of the semicircular breakwater unit. The semi-circular breakwater caisson is transformed into the energy capturing air chamber, the oscillating water column type wave energy power generation device is built on the basis of the breakwater caisson, one box has two purposes, and the building cost of the oscillating water column type wave energy power generation device is greatly reduced. The wave force acting on the semicircular caisson points to the circle center, the generated total horizontal force is small, and the anti-sliding and anti-tilting stability of the structure is facilitated. According to the semi-circular breakwater, wave energy in front of the breakwater can be converted into electric energy, wave reflection in front of the breakwater and wave transmission behind the breakwater are reduced, the load acting force in front of the breakwater is reduced, and the wave dissipation performance, overall stability and safety of the semi-circular breakwater are further improved. The wave energy power generation field can be arranged in an array mode on the head wave side of a target sea area, the wave energy power generation field with the breakwater function is formed, and a high-power power supply system can be formed while coast protection is met.

Description

technical field [0001] The invention belongs to the technical field of coastal engineering structures, and in particular relates to a semicircular breakwater unit integrating an oscillating water column type wave energy generating device, and a breakwater formed by the unit. Background technique [0002] With the depletion of fossil fuel reserves, the demand for renewable energy continues to increase, and the development and utilization of clean renewable energy has more prominent significance. The ocean, which covers 71% of the earth's area, provides us with inexhaustible ocean energy, which is the most important one; wave energy is the most researched and most widely used ocean energy recently. energy. Among all kinds of wave energy converter equipment, the concept of oscillating water column (OWC) wave energy generation device is widely used and has been extensively researched in the past few decades. The high energy conversion efficiency and reliability of the equipment...
