Floating cofferdam type wave generating set

Abstract

The invention discloses a floating cofferdam type wave energy generating set, which comprises a tower convergent wave pool consisting of a platform and a multistage conic pool. The bottom of the tower convergent wave pool is divided into a plurality of ballast tanks and provided with a water level sensor, the upper cavities of the ballast tanks are filled with a buoyancy material, the platform is arranged on the buoyancy material of a groove in the middle of the convergent wave pool, and the platform is provided with a controller, a compressed air system and a baffle wall; the baffle wall is provided with a sensor, the low level of each stage of the convergent wave pool is provided with a pipeline leading to the sea level, the pipeline is internally provided with a Kaplan turbine and an asynchronous generator, the floating cofferdam type wave energy generating set is connected with anchor pipers with swivel links through anchor chains, and the anchor pipers are anchored at the bottom of the sea. According to the draught height of a wave height adjusting device, the floating cofferdam type wave energy generating set is not influenced by tide level and limited by terrain, always works towards the waves all around, can catch the wave energy as much as possible under various conditions, and has the advantage of high working efficiency; only the Kaplan turbine is the unique movable component so that the reliability of the whole set is improved.

Description
