Abstract

The invention provides a ''mushroom type'' oscillating water column type wave energy conversion device and belongs to the technical field of new energy utilization. The ''mushroom type'' oscillating water column type wave energy conversion device comprises an air chamber, a pile foundation structure and a turbine power generation device. The air chamber is composed of a cylindrical ring body and a hemispherical ring body. The hemispherical ring body is arranged on the cylindrical ring body, and the radius of the hemispherical ring body is the same as that of the cylindrical ring body. A pore pipeline is arranged on the upper portion of the hemispherical ring body. The pore pipeline is connected with the turbine power generation device capable of rotating in the same direction under the two-way airflow function. A crossed support beam is arranged on the upper portion of the pile foundation structure and used for supporting the air chamber. A distance is formed between the crossed support beam and the top of the air chamber so that the airflow can smoothly pass the pore pipeline. According to the ''mushroom type'' oscillating water column type wave energy conversion device, based on the characteristic of 360-degree omnidirectional wave energy absorption, the absorption rate of wave energy is increased; the stability of the device can be guaranteed by the adoption of the fixed type structure, the power generation efficiency is improved, and maintenance is facilitated; and the ''mushroom type'' oscillating water column type wave energy conversion device is combined with the pile foundation structure, and it is possible for the device to be applied to the offshore position from the shore.

Description

technical field [0001] The invention belongs to the technical field of new energy utilization, and in particular relates to a "mushroom-shaped" oscillating water column wave energy conversion device. Background technique [0002] In today's world, with the depletion of traditional fossil energy such as oil and coal, and the environmental problems brought about by traditional energy are becoming increasingly severe. Countries around the world are increasingly demanding clean and renewable energy. Wave energy is a renewable energy with broad development prospects. At present, people have developed various wave energy conversion devices. Due to its simple structure and easy maintenance, the oscillating water column wave energy conversion device is a wave energy conversion device that is paid the most attention, invests the most in research, and builds the most in various countries. [0003] There are mainly two types of oscillating water column wave energy conversion devices:...
