This invention provides a porous wave-damping plate for aquaculture cages, specifically belonging to the field of wave-damping technology for aquaculture cages. It comprises a porous plate, wave-damping buoys, and a hollow cavity structure, forming a highly efficient energy dissipation system. The alternating openings on the surface of the porous plate allow waves to pass through. When waves impact the plate, seawater enters the hollow cavity and drives the internal wave-damping buoys to generate minute movements and collisions, thereby significantly reducing wave height and impact force. This directly protects the fish in the cage from the impact of violent water currents. The invention includes a plate body, which is detachably and fixedly installed on the outside of the cage. The plate body is a hollow plate-like structure with through holes on both the front and back sides, and the cavity of the hollow plate-like structure is filled with several wave-damping buoys for dissipating wave energy. It includes multiple plate bodies, which are spliced ​​together to form a wave-damping plate assembly. The upper end of the plate body is provided with a tenon, and the lower end of the plate body is provided with a mortise. Adjacent plates are interlocked and positioned by the tenon and mortise.

The application discloses an offshore photovoltaic power generation protection system based on air curtain wave abatement, and relates to the technical field of photovoltaic power generation protection devices. The system not only provides reliable protection for offshore photovoltaic power generation energy storage devices, but also reduces the dependence on external energy and improves the energy self-sufficiency rate of the whole system. The system comprises a photovoltaic power generation energy storage device and a plurality of air curtain wave abatement devices arranged on the periphery of the photovoltaic power generation energy storage device. The photovoltaic power generation energy storage device comprises photovoltaic panels arranged on a mounting structure and solar cells electrically connected with the photovoltaic panels. The air curtain wave abatement device comprises an air compressor and an exhaust pipe. The air compressor is arranged on the mounting structure and located outside the photovoltaic power generation energy storage device. The exhaust pipe is laid in the underwater area outside the solar cells and has an inlet end in communication with the air compressor. A plurality of exhaust holes and counterweights are arranged on the exhaust pipe. The air compressor is electrically connected with the solar cells. The application is used for improving the performance of the photovoltaic power generation protection system.

The invention relates to a double-body floating type anti-storm mass transfer system which is characterized in that a porous water-permeable plate is laid on a connecting bridge frame, and a mass transfer assembly is arranged on the porous water-permeable plate; semi-submersible floating bodies are arranged on the left side and the right side of the connecting bridge frame respectively, a front wave absorbing device is movably connected to the wave facing side of the connecting bridge frame through a hydraulic damper, and a rear wave absorbing device is fixedly arranged on the wave back side of the connecting bridge frame; the wave absorbing device comprises more than three porous grid plates, the pore diameters of the more than three porous grid plates are sequentially reduced from outside to inside, a gap is reserved between every two adjacent porous grid plates, and the lengths of the gaps are different. The front wave absorbing device can swing around a shaft along with the action of waves, absorbs and dissipates a large amount of wave energy, and interferes with the wave phase. The penetrating waves continue to spread backwards, are diffracted when passing through a slit between the double porous grid plates, and are further weakened through porous friction and vortex dissipation. And a calm shielding area of which the wave height is obviously reduced is formed in the area where the mass transfer assembly is located.
