Example Embodiment

[0064] Example 1:

[0065] Such as figure 1 As shown, the floating breakwater with wave power generation function provided by this embodiment includes a floating body 1 and a mooring system 2;

[0066] The floating body 1 includes:

[0067] A first box 3, the first box 3 includes a front cavity 4 and a rear cavity 5, both of which are arranged back and forth in a direction parallel to the sea level; the front cavity 4 forms an arc-shaped flow channel 6 The rear cavity 5 includes an upper cavity 49 and a lower cavity 50, both of which are arranged up and down in a direction perpendicular to the sea level, the upper cavity 49 forms a first water storage tank 7; the lower cavity 50 forms A direct flow channel 8; the center line of the first opening 9 of the arc-shaped flow channel 6 is parallel to the sea level, and is butted with one side opening of the lower cavity 50, and the second opening 10 is higher than in the direction perpendicular to the sea level The first opening 9 has a ...

Example Embodiment

[0088] Example 2:

[0089] This embodiment provides a floating breakwater with wave power generation function, and its general structure is the same as that of embodiment 1, such as Figure 7 As shown, but the floating body 1 in this embodiment also includes an automatic collection system for floating objects at sea;

[0090] The automatic collection system for floating objects at sea includes:

[0091] A conveyor belt assembly 35, which is located outside the opening on the side of the lower cavity 50 that faces away from the first opening 9, and completely shields the side opening; the conveyor belt 36 of the conveyor belt assembly 35 forms an angle of 30-60° with the sea level The driving roller 37 of the conveyor belt assembly 35 is hinged to the third bracket 39 extending outward from the first box 3 through the first rotating shaft 38, and the driven roller 40 passes The second rotating shaft 41 is hinged to the first box body 3, and the driven roller 40 is higher than the dri...

Example Embodiment

[0096] Example 3:

[0097] This embodiment provides a floating breakwater with wave power generation function, and its general structure is the same as that of embodiment 2, such as Figure 8 As shown, but in this embodiment, a first partition 45 is provided in the lower cavity 50 of the first box 3, and the first partition 45 extends in a direction parallel to the sea level; A second partition 46 is provided in the first storage bin 7, and the second partition 46 extends in a direction perpendicular to the sea level; a third partition is provided in the second storage bin 12 of the second tank 11 The third partition 47 extends in a direction perpendicular to the sea level.

[0098] The above-mentioned partitions can all play the role of breaking waves, weaken the direct impact force of the wave current on the floating body 1 and protect the floating body 1.

Abstract

The invention discloses a floating breakwater, and particularly relates to a floating breakwater with a wave energy power generation function. According to the structure, a first water storage bin ona first box body and a second water storage bin on a second box body are used for achieving anterior-posterior balance of the floating breakwater, and the effect that a straight runner formed in a lower cavity of the first box body is completely immersed in the water is guaranteed; the second box body directly faces waves as the head sea end; the waves enters the straight runner through an openingof a first opening away from an arc-shaped runner on the straight runner after passing through floating bodies, then periodic wave motion is formed in the arc-shaped runner, air flow and/or water flow is driven to flow through a turbine power generation system, and then a turbine power generator is driven to generate power. In addition, the invention provides a breakwater system. By means of thefloating breakwater and the breakwater system, the technical effects of improving the wave absorbing performance of the floating breakwater and achieving functional diversification are achieved, and the floating breakwater and the breakwater system have the advantages that the wave absorbing performance is good, and energy conversion efficiency is high.

Description

technical field [0001] The invention relates to a floating breakwater, in particular to a floating breakwater with the function of generating wave energy and a wave-proof system. Background technique [0002] Floating breakwater is a type of anti-wave structure built on the water surface based on the principle that wave energy is mainly concentrated on the surface of the water body. It consists of a floating body and an anchoring system. [0003] Compared with the traditional fixed breakwater, it has many advantages such as low engineering cost, easy material acquisition, quick construction, no need for foundation treatment, convenient disassembly and assembly, and environmental protection. It can be widely used in deep-water ports, offshore enclosures, and artificial sea bathing beaches , yacht docks, aquaculture bases, military ports, etc., have broad application prospects and huge market space in the fields of national economy, people's livelihood, and national defense se...
