Embodiment 1

[0020] Facing the island’s demand for wave control and island energy supply, this invention integrates the oscillating buoy type wave energy device and the comb type breakwater system, and proposes a comb type breakwater system that takes into account both oscillating buoy type wave energy generation, hereinafter referred to as OB&CTBW system (Oscillation Buoy & Comb Type Breakwater). The proposal of the system aims to provide a new type of breakwater system that takes into account the efficiency of power generation and the overall wave dissipation effect of the breakwater around the strategy of building a strong ocean country and the layout of islands and reefs. The invention can convert a part of the wave energy into electric energy, alleviate the power supply problem of sea islands, and at the same time reduce the total horizontal wave force on the breakwater and enhance its structural stability.

[0021] The present invention adopts scheme as follows:

Embodiment 2

[0036] The OB&CTBW system is placed on the riprap bed laid on the seabed, and consists of several figure 1 The units shown are arranged in succession along the axial direction of the breakwater. The OB&CTBW system includes two parts: the improved comb breakwater system and the floater power generation device. The improved comb-type breakwater part includes a chamfered caisson 1, a diversion wall 2, a breast wall 3, a wing plate 4, and a bottom plate 5, wherein the chamfered caissons 1 are arranged at intervals along the axial direction of the breakwater, and the wing plates 4 are arranged between adjacent caissons The breast wall 3 is set on the chamfered caisson 1 and the wing plate 4 to enhance the integrity of the structure; the bottom plate 5 is placed on the bottom of the breakwater wave dissipation chamber to provide fixing conditions for the buoyant power generation device. The floater type power generation device is placed in the comb-type breakwater wave dissipation ...

Abstract

The invention discloses a comb breakwater system simultaneously giving consideration to oscillating float type wave energy generation, and belongs to the technical field of ocean power generation andwave resistance. The comb breakwater system comprises chamfering caissons 1, a diversion wall 2, breast walls 3, wing plates 4, a bottom plate 5 and a float type power generating device; wherein the chamfering caissons 1 are arranged in the axial direction of a breakwater at intervals to form a breakwater wave-eliminating chamber, the wing plates 4 are arranged on the back wave surfaces between the adjacent caissons; the breast walls 3 are arranged above the chamfering caissons 1 and the wing plates 4, and therefore the integrity of the structure is enhanced; and the bottom plate 5 is immersedat the bottom of the breakwater wave-eliminating chamber, and the float type power generating device is fixed on the bottom plate 5. From the point of view of design, two functions are realized in one project, and the overall cost is reduced; from the point of view of construction, the comb breakwater provides a fixed condition for the float type wave energy device and reduces the anchoring costof the wave energy device; and from the point of view of later period operation and maintenance, assessment of the breakwater and maintenance of the power generation device can be carried out simultaneously during one attendance period, and later period operation and maintenance are facilitated.

Description

technical field [0001] The invention relates to the technical field of ocean power generation and wave protection, in particular to a comb-type breakwater system that takes into account both oscillating buoy-type wave energy generation. Background technique [0002] Island construction is one of the key development areas in my country in the near future. The breakwater is an essential part of the construction of the island, which can provide a stable water environment for the island, and provide protection and shelter for the ships entering and leaving the island; however, affected by the geographical location, the power supply problem of the island reef has become the primary problem that needs to be solved urgently. It is a necessary and feasible solution to seek new clean energy such as wave energy from the sea around the island. [0003] The comb-type breakwater structure is based on the ordinary vertical breakwater, taking out the caisson in an appropriate proportion a...
