Abstract

The invention discloses a Y-shaped wave energy absorbing and converting device. The Y-shaped wave energy absorbing and converting device is composed of N wave power generation units, wherein the N wave power generation units are arranged in a triangular shape. Two rows of wave power generation devices are arranged on the platform on each edge of the triangular shape. Foundation platforms are fixed to the seabed in a tripod mode. Each buoy is fixed to the corresponding fixed foundation platform through a U pair and a P pair by means of a chain and has three freedom degrees including heaving, pitching and rolling. A series of spherical hinge connecting rods are arranged on the periphery of each buoy, wherein the spherical hinge connecting rods are spherically hinged to a hydraulic cylinder. An inner ring of each U pair is fixedly connected with one end of a piston rod. All the hydraulic cylinders are fixed to the foundation platforms. Under the motivation of waves, the mechanical energy of the buoy is converted into hydraulic energy through the hydraulic cylinders, the hydraulic energy is stored in an energy accumulator, the energy accumulator discharges high-pressure oil to drive hydraulic motors to rotate, the hydraulic motors are connected with generators, and then power generation is conducted; each wave power generation device is fixed to the corresponding foundation platform. The Y-shaped wave energy absorbing and converting device has the advantages that the power is high, the conversion efficiency is high and maintenance is convenient.

Description

Technical field [0001] The invention relates to the field of new energy equipment, in particular to a Y-shaped wave energy absorption and conversion device. Background technique [0002] The current oscillating float type ocean wave power generation technology is basically limited to absorbing single degree of freedom energy, and the power generation of a single ocean wave power generation device is low. Summary of the invention [0003] Aiming at the defects in the prior art, the purpose of the present invention is to provide a Y-shaped wave energy absorption and conversion device. [0004] The present invention is realized through the following technical solutions: [0005] A Y-shaped wave energy absorption and conversion device, including a basic platform, connecting rods, hydraulic cylinders, floats, counterweights, motors, generators, hydraulic oil tanks, hydraulic pipelines, etc. During the power generation process, the movement of the buoy drives the movement of the plunger r...
