The invention relates to a floating type double-turbine wave energy absorption device, belongs to the technical field of renewable energy utilization, and solves the problems that an existing floating type wave energy absorption device cannot be suitable for a wide wave frequency range, high energy absorption efficiency, high generator working efficiency and low manufacturing and maintenance cost at the same time. According to the invention, the motor rotor and the motor stator still have a relatively large rotating speed difference when floating up and down on the buoy shell relatively by utilizing the same-direction rotation of the double turbines and the turning and acceleration effects of the planet row, so that efficient power generation is realized; the upper turbine blade and the lower turbine blade can rotate around the shaft, so that when the buoy shell moves upwards/downwards, the rotating directions of the rotor and the stator of the motor are not changed, and the generator works stably; the buoy shell does not rotate under seawater resistance, energy dissipation is low, and the energy conversion efficiency is high; the double turbines rotate in the same direction, abrasion of a bearing between the inner transmission shaft and the outer transmission shaft is small, the generator is isolated from seawater through a sealing device, corrosion resistance is achieved, and manufacturing and maintenance cost is low.

    本发明涉及一种浮式双涡轮波浪能吸收装置,属于可再生能源利用技术领域,解决了现有浮式波浪能吸收装置不能兼顾适用于宽波浪频率范围、高能量吸收效率、高发电机工作效率和低制造维护成本的问题。本发明的利用双涡轮的同向旋转,并通过行星排的变向和加速作用,使得电机转子和电机定子在浮标外壳上下浮动较小时,仍具有较大的转速差,进而高效发电;上、下涡轮叶片都能绕轴旋转,使得在浮标外壳的向上/下运动时,电机转子和定子的转动方向不变,进而发电机工作稳定;浮标外壳不在海水阻力下旋转,能量耗散少,能量转化效率高;双涡轮同向旋转,内外传动轴之间的轴承的磨损小,并通过密封装置隔绝发电机与海水,抗腐蚀,制造维护成本低。
