The cylinder of holes, each circular hole penetrates from the upper surface of the floating breakwater to its lower surface, and the moon pool structure (5) is based on each equal-radius circular hole, from top to bottom on the axis of each hollow cylinder A steam turbine (4) is placed underneath, and the steam turbine is fixed to the inner surface of the hollow cylinder by using a fixed bearing 4-1. The power genera...

Embodiment 2

[0030] We have designed the different mechanisms of the device as follows.

[0031] The shape of the floating breakwater is a flat cylinder, which is composed of a floating body and an anchoring device. The material of the floating body is aluminum alloy, and the surface of the cylinder is covered with anti-rust paint, which plays the role of anti-corrosion and warning. The floating body adopts the mooring method of multi-point scattering system. The floating body is placed horizontally from top to bottom. The upper end of each anchor cable is hinged on the lower surface of the floating body. The lower end of the anchor cable is connected to the anchor block. and mooring cables to moor the floating breakwater at sea

[0032] The mooring device of the floating breakwater structure includes an anchor block (3) and an anchor cable (6). Fixed connection, the anchor cable is connected to the seabed horizontally, and the anchor point is only subjected to horizontal force.

Description

technical field [0001] The invention belongs to the technical field of wave power generation, and in particular relates to a moon pool oscillating water column wave energy power generation device based on a floating breakwater. Background technique [0002] Energy is a hot topic in today's era. With the rapid development of the world economy, human demand for energy is becoming larger and larger. However, environmental pollution and the total amount of fossil energy are constantly decreasing, making people realize that the development and utilization of clean energy is imminent. Among them, the wave energy that can be provided in the ocean has the advantages of high energy density and wide distribution, and can provide energy relatively stably. At present, various forms of wave energy conversion devices have been widely studied, and how to efficiently harvest energy will become a major research focus. [0003] The development and utilization of wave energy in my country be...
