Abstract

The invention discloses a wave energy power generation unit and a wave energy power generation device comprising the same and a wave energy power generation method. The wave energy power generation unit comprises a plurality of single rear bent pipe structures connected in parallel, each single rear bent pipe structure comprises a bent pipe and a floating body, each bent pipe comprises a bent pipe vertical section and a bent pipe horizontal section, the upper portions of the horizontal sections of the bent pipes are connected with the floating bodies, the vertical sections of the adjacent bent pipes communicate with one another, the vertical section of the bent pipe of one single rear bent pipe structure is connected with an air chamber pipeline, and an air turbine is arranged in the air chamber pipeline. According to the wave energy power generation unit and the wave energy power generation device comprising the same and the wave energy power generation method, the plurality of single rear bent pipe structures are combined and connected, the vertical sections of the adjacent bent pipes communicate with one another, the same air turbine does work, the flow of reciprocating airflow in an air chamber can be increased, the utilization efficiency of wave energy is remarkably improved, and the installed capacity is improved; and a thought of improving the wave energy utilization efficiency by forming resonance is provided, and the maximum water surface movement wave height in the air chamber is obtained in the process that parameter optimization is carried out on the wave energy power generation device.

Description

technical field [0001] The invention relates to the technical field of wave energy conversion, in particular to a wave energy generating unit, a wave energy generating device, and a wave energy generating method. Background technique [0002] With the in-depth implementation of my country's marine strategy, there is an urgent need to develop an offshore renewable energy power supply system that meets the development of deep and open seas. The single BBDB device (Back Bent Duct Buoy wave energy generation device) is an existing device used in the utilization of ocean wave energy. The device consists of three parts, the floating body, the water inlet and the opposite wave direction. elbow, and rear air turbine. Due to the simple structure of the back-bend device, the rear-end air turbine is not in contact with seawater, and there are no underwater moving parts, the service life of the device is significantly longer than that of other wave energy generation devices.

Problems solved by technology

However, due to the wave force, the rear bending device has six degrees of freedom of movement, and the scattered point array is not conducive to the energy capture of the rear device due to the shading effect.

In addition, there is not much research on how to make full use of the wave energy to convert it into the oscillation of the air in the air chamber for the single back bend device.

The Chinese patent application publication number CN 108425788A discloses a one-way impulsive wave energy generating device. A fixed block and a first fixed ring are installed in the air cabin. A movable rod that rotates around it; the first end of the intake elbow is installed in the draft compartment below the aluminum alloy cover plate, the second end is located on the upper part of the buoyancy chamber and is provided with a second fixing ring, and the second end of the intake elbow is There is a rubber sheet that can be attached to or loosen the second fixed ring inside the end; the straight air outlet pipe is installed on the upper part of the air cabin, and is connected with the installation pipe and the one-way impulsive air turbine through the first flange, that is, Said that this scheme only improves the internal structure of the single back bend pipe structure, and cannot achieve the effect of better utilization of wave energy

The Chinese patent application publication number CN 107044379 A discloses a self-propelled green energy power supply device at sea. The hull is provided with at least one wave energy generating unit group, and the wave energy generating unit group includes the right wave energy generating unit and the left The wave energy generation unit, that is to say, the scheme installs the single back bend pipe structure on the hull, but obviously reduces the vibration frequency of the back bend pipe structure itself, and this scheme only utilizes the single back bend pipe Structure, unable to achieve better utilization of wave energy
