Embodiment Construction

[0023] The content of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0024] The floating wave energy breakwater of the present invention is composed of multiple units, and the unit structure is composed of five parts: as figure 1 As shown, the first part is the main body 1 of the duck-type device, which is the rotating part of the unit. The cross-sectional shape is similar to that of a duck egg. Wavelength design, there is a raised semicircular buoy on the water line; the main body head 3 is exposed to the water surface, and the shape is not limited. The second part is the main shaft 4, the main shaft 4 penetrates into the cylindrical structure of the main body tail 2, and the main body 1 and the main shaft 4 of the canard device can rotate relatively. The third part is the underwater appendage 5. The underwater appendage 5 is mainly composed of a horizontal plate 6, a vertical plate 7 and a tr...

Abstract

The invention provides a floated breakwater for utilizing wave energy, and the floated breakwater can provide a wave-breaking wave-preventing function within any range in any water area. The breakwater is characterized in that an efficient floated wave energy absorption device is taken as a unit to build the breakwater, so that the wave height of waves is greatly reduced after the waves pass through the novel breakwater, thus ships or other objects in the water area behind the device can avoid the waves. Arrays formed by a plurality of the devices can quickly build the breakwater within any range in any water area in accordance with demands. While the waves are broken, absorbed wave energy can be converted into other forms of energy. The breakwater is easy to build and construct, can be built massively on land, can be delivered to a targeted water area, can be put into use massively, is not influenced by sea state, marine geology and sea level in the construction process, can be predicted and controlled within the construction period and is wide in application aspects. In addition, the floated breakwater for utilizing the wave energy can be used for replacing a temporary cofferdam on sea.

Description

technical field [0001] The invention belongs to the technical field of marine engineering, in particular to a floating breakwater utilizing wave energy. technical background [0002] A breakwater is a building built in the port waters or a certain part of it to prevent waves from directly intruding into the port, so that the water surface in the port is relatively calm and ships can berth and load safely. Breakwater structures can generally be divided into heavy and light types: the former is a traditional and commonly used type of breakwater, including slope embankment, straight wall embankment and mixed embankment, etc. This type of breakwater technology must be built from the seabed and is only suitable for water depths less than 10m , The area with small waves, otherwise the cost will be high; and it will cause a large amount of earth and stone to enter the sea, causing adverse environmental impacts. At the same time, the existing breakwater technology has the problem o...
