所述椭球形摆体1截面椭圆的长轴方向与摆臂连接，短轴方向与海面垂直，长轴长度是短轴长度的50～100倍，椭球形摆体1吸收海浪上下波动能，当海浪方向改变时，吸收效率不变或椭球形摆体1绕转轴3旋转后，吸收效率也不发生改变。 The long axis direction of the elliptical section ellipse of the ellipsoidal pendulum body 1 is connected to the swing arm, the short axis direction is perpendicular to the sea surface, and the length of the long axis is 50 to 100 times the length of the short axis. When the wave direction changes, the absorption efficiency remains unchanged or after the ellipsoidal pendulum 1 rotates around the rotation axis 3, the absorption efficiency does not change.
所述第一大圆锥齿轮5和第二大圆锥齿轮7为钢制构件。 The first large bevel gear 5 and the second large bevel gear 7 are steel components.
本发明中将椭球形摆体摆动转换成单向旋转运动的工作过程： In the present invention, the working process of converting the swing of the ellipsoidal pendulum into one-way rotary motion:
当发电装置由静止状态开始工作，椭球形摆体1从上向下摆动，转轴3沿X方向顺时针旋转，第一单向离合器4处于接合状态，带动第一大圆锥齿轮5沿X轴方向顺时针旋转，驱动小圆锥齿轮轴沿Y轴方向逆时针旋转，第二大圆锥齿轮7在小圆锥齿轮9的带动下沿X轴方向逆时针旋转。因第二单向离合器6与第一单向离合器4镜反对称，第二单向离合器6处于分离状态，第二大圆锥齿轮7空转，只起到飞轮的作用，用于储存能量降低运转的波动性。当椭球形摆体1由下往上运动时，转轴3沿X轴方向逆时针旋转，第一单向离合器4处于分离状态，第一大圆锥齿轮5空转，在较短的时间内，转轴3的速度还小于第二大圆锥齿轮的速度，第二单向离合器6未接合，此时主要由两大圆锥齿轮储存的旋转动能带动小圆锥齿轮9旋转，因为发电机的负载作用，两大圆锥齿轮速度略微降低，椭球形摆体1由下向上运动到某一时刻，转轴3的速度开始大于第二圆锥齿轮7的转速，第二单向离合器6接合，驱动第二大圆锥齿轮7继续沿X轴方向逆时针转动，同时驱动小圆锥齿轮轴9继续沿Y轴方向逆时针旋转。椭球形摆体1交替往复摆动，第一单向离合器4与第二单向离合器6交替驱动，带动发电机14连续稳定发电，交替空转的两大锥齿轮起到了飞轮的作用，显著降低转速的波动性。 When the generator starts to work from a static state, the elliptical pendulum 1 swings from top to bottom, the rotating shaft 3 rotates clockwise along the X direction, the first one-way clutch 4 is in the engaged state, and drives the first large bevel gear 5 along the X-axis direction Rotating clockwise, the small bevel gear shaft is driven to rotate counterclockwise along the Y-axis direction, and the second large bevel gear 7 is driven by the small bevel gear 9 to rotate counterclockwise along the X-axis direction. Because the second one-way clutch 6 is mirror-antisymmetric to the first one-way clutch 4, the second one-way clutch 6 is in a disengaged state, and the second large bevel gear 7 is idling and only plays the role of a flywheel, which is used to store energy and reduce the speed of operation. volatility. When the elliptical pendulum 1 moves from bottom to top, the rotating shaft 3 rotates counterclockwise along the X-axis direction, the first one-way clutch 4 is in a disengaged state, and the first large bevel gear 5 is idling. In a short time, the rotating shaft 3 The speed is still lower than the speed of the second largest bevel gear, and the second one-way clutch 6 is not engaged. At this time, the rotational kinetic energy stored by the two large bevel gears drives the small bevel gear 9 to rotate. Because of the load of the generator, the two large bevel gears The speed of the gear decreases slightly, and the elliptical pendulum 1 moves from bottom to top until a certain moment, the speed of the rotating shaft 3 begins to be greater than the speed of the second bevel gear 7, the second one-way clutch 6 is engaged, and the second large bevel gear 7 is driven to continue to move forward. The direction of the X axis rotates counterclockwise, and at the same time, the small bevel gear shaft 9 is driven to continue to rotate counterclockwise along the direction of the Y axis. The elliptical pendulum 1 alternately reciprocates, the first one-way clutch 4 and the second one-way clutch 6 are alternately driven, and the generator 14 is driven to generate electricity continuously and stably. volatility.
当海浪较大时，椭球形摆体1绕转轴3有较大的自由旋转角度，不会因为转角限制而受到冲击，提高了抗海浪的能力。椭球形摆体1翻转180°后，小圆锥齿轮9的转向不变，发电装置与未翻转前工作特性一致。翻转后椭球形摆体1从上向下运动时，第二单向离合器6接合，从下向上运动时，第一单向离合器4结合。椭球形摆体1具有旋转对称性，且主要吸收海浪上下波动能，海浪传播方向改变时，椭球形摆体1的能量吸收率不变。 When the sea waves are large, the ellipsoidal pendulum body 1 has a large free rotation angle around the rotating shaft 3, and will not be impacted due to the limitation of the rotation angle, thereby improving the ability to resist sea waves. After the ellipsoidal pendulum body 1 is overturned by 180°, the steering of the small bevel gear 9 remains unchanged, and the power generation device has the same working characteristics as before the overturning. After turning over, when the elliptical pendulum 1 moves from top to bottom, the second one-way clutch 6 is engaged, and when it moves from bottom to top, the first one-way clutch 4 is engaged. The ellipsoidal pendulum 1 has rotational symmetry, and mainly absorbs the up and down wave energy of the ocean waves. When the wave propagation direction changes, the energy absorption rate of the ellipsoidal pendulum 1 remains unchanged.
