Sinking water wave power generation device based on the principle of stewart platform

Abstract

The invention discloses a sunken type water wave power generation device based on a stewart platform principle. A stewart platform comprises a regularly polygonal center platform, fan-shaped floating tables connected to all the platform edges of the center platform through hinge mechanisms, and a fan-shaped floating table supporting flat plate arranged below the center platform, wherein hydraulic cylinders are supported between all the fan-shaped floating tables and the fan-shaped floating table supporting flat plate according to the following mode: cylinder bodies are connected to the fan-shaped floating table supporting flat plate through spherical hinges; hydraulic rods are connected to guide rail sliding blocks of the corresponding fan-shaped floating tables through spherical hinges; a unidirectional output gear conversion box is arranged on the fan-shaped floating table supporting flat plate, and is used for concentrating power of ratchet-gear dual-output hydraulic motors correspondingly driven by all the hydraulic cylinders and unidirectionally conveying the power to an output shaft; and the output shaft drives a power generator in a balance floating barrel at the bottom of the fan-shaped floating table supporting flat plate. The sunken type water wave power generation device disclosed by the invention has a large degree of freedom, can flexibly adapt to the unpredictable fluctuation of waves, and is high in conversion efficiency and wide in application range.

Description

technical field [0001] The invention relates to power generation equipment, in particular to a sunken water wave power generation device based on the principle of a stewart platform. Background technique [0002] Wave energy is the most widely distributed in various waters, with high energy flow density, no pollution, wide distribution, renewable, large reserves, etc., but the current utilization rate is low. [0003] All countries in the world have research on wave power generation. The first to do research on wave energy is Paris, followed by the United Kingdom. Wave energy power generation has developed relatively maturely so far. There are more than 1,500 patents for various wave energy conversion devices, such as "nodding duck" type, pendulum type, and oscillating float type. Due to the existing wave energy conversion The device is basically used in ocean waves, and the volume of the device is required to be large, so it is difficult to apply to fresh water such as inl...
