Embodiment 1

[0024] The vertical caisson structure 8 is used as the main structure, and is fixed on the seabed through the BenQ bed, such as Figure 4 with Figure 5 , 3 rows of compartments are arranged on the port side, and 4 compartments 9 are arranged in each row. Two rows of compartments are arranged on the wave facing side for placing the oscillating water column type power generation device 1 . The vertical upper wave baffle 2 can block wave propagation; the slope-type lower wave baffle 3 has the effect of gathering waves; the multi-arc transition surface 4 designed at the bottom of the energy-harvesting air chamber 5 can reduce wave reflection, reduce wave energy loss, and improve increase the efficiency of energy capture, and reduce the scouring and load of waves on the bottom surface of the water body inlet and outlet of the energy capture chamber 5 at the same time. The two-way impingement turbine of the air turbine device 7 is located in the double-sided contraction airflow c...

Abstract

The invention discloses a vertical type caisson breakwater system with a wave-energy electricity generation function, belonging to the breakwater field. The vertical type caisson breakwater system includes an oscillating water column-typed electricity generation device, a machine room and a vertical type caisson structure. The oscillating water column-typed electricity generation device includes a vertical type upper wave resisting plate, a slope-typed lower wave resisting plate, a multi-arc section transition face, and an energy collecting air chamber. The machine room includes an air turbine device and a generator group. Compared with the prior art, the vertical type caisson breakwater system combines the oscillating water column-typed electricity generation device and the vertical type caisson structure, and thus, shore bases can be effectively prevented from being broken by waves. Wave energy can be used at the same time. The electricity generation efficiency is higher. The vertical type caisson breakwater system with a wave-energy electricity generation function has the advantages of excellent stability of the whole structure, low project cost and easy construction, and is suitable for great depth of water. The vertical type caisson breakwater system with a wave-energy electricity generation function has stronger viability and provides new solution for solving the problem of electricity supply on sea islands.

Description

technical field [0001] The invention belongs to the field of breakwaters, and in particular relates to a vertical caisson breakwater system with the function of generating wave energy. Background technique [0002] With the development of caisson breakwaters and shore-type wave energy generation devices, scholars at home and abroad have conducted in-depth research on this. Giovanni Malara et al. proposed a new type of U-OWC caisson breakwater structure, and combined physical model tests and numerical simulations to verify the reliability of the structure; Paolo Boccotti carried out research on the wave energy conversion coefficient of the new U-OWC caisson breakwater, and used The physical model test proves the stability of the structure. Qin Hui et al. designed a composite structure combining a caisson breakwater with constricted water channels and an OWC air chamber. The hydraulic physics model test was used to study. As well as the wave reflectivity in front of the stru...
