Preferred embodiment of utility model

As shown in Fig. 1 and Fig. 2, it is a schematic cross-sectional structure diagram of the utility model ocean wave power generation conversion device and a right side view of the figure with a partial cutaway, the device includes a box body 10, an energy input mechanism 20, an energy storage conversion mechanism 30, and Energy output mechanism 40 .

The energy input mechanism 20 is composed of a buoy 202 , a rocker arm 204 , an internal meshing ratchet mechanism 206 , a rocker arm shaft 208 , and an input gear 210 . One end of the rocking arm 204 is fixed on the buoy 202 with two screws, and the other end is fixedly connected with the rocking arm shaft 208. The inner meshing ratchet mechanism 206 is vacantly sleeved on the rocking arm shaft 208, and the rocking arm shaft 208 and the inner meshing ratchet mechanism 206 Its own ratchet (not shown) is connected, and the input gear 210 is fixedly connected to the outer cylindrical surface of the inner meshing ratchet mechanism 206 and can rotate together with it. The buoy 202 and the rocker arm 204 of the energy input mechanism 20 are arranged outside the box body 10; the internal meshing ratchet mechanism 206 and the input gear 210 are arranged inside the box body 10; and the rocker arm shaft 208 passes through the opposite sides of the box body 10 .

When sea waves surged up the buoy 202, the rocking arm 204 that was fixedly connected with the buoy 202 also swung upwards, and the rocker shaft 208 fixed on one end of the rocking arm 204 rotated clockwise thereupon. On the rocker shaft 208, and the rocker shaft 208 is connected with the ratchet of the internal meshing ratchet mechanism 206 itself, therefore, the ratchet pushes the internal meshing ratchet mechanism 206 to rotate, and the input gear 210 fixed on its outer cylindrical surface also follows The rotation of the input gear 210 meshes with the energy storage gear 302 to transmit energy from the energy input mechanism 20 to the energy storage conversion mechanism 30 . So far, an energy input process is completed.

When the buoy 202 descended under the action of sea waves and dead weight, the rocker 204 fixedly connected with the buoy 202 also swung downwards, the rocker shaft 208 fixed on one end of the rocker, and the ratchet pawl fixed with the rocker shaft 208 It also rotates counterclockwise thereupon, but at this time, because the internally engaging ratchet mechanism 206 cannot rotate in the opposite direction, the energy input mechanism 20 does not perform work.

When the utility model ocean wave power conversion device changes its own transmission ratio according to different needs, the volume size of the buoy 202 and the length of the rocker arm 204 can be changed accordingly.

The energy storage conversion mechanism 30 is arranged inside the box body 10 and is composed of an energy storage gear 302 , a main shaft 304 , a planar dimple spring 306 , a ratchet mechanism 308 , and a housing 310 . The energy storage gear 302 is arranged outside the housing 310 and is connected with it by a key. The planar dimple spring 306 is arranged inside the casing 310 and is arranged parallel to the energy storage gear 302 and the ratchet mechanism 308 . The main shaft 304 passes through the energy storage gear 302, the plane dimple spring 306, and the ratchet mechanism 308 at the same time, and is fixedly connected with the plane dimple spring 306; The ratchet mechanism 308 is fixedly connected with the housing 310 .

When the energy storage gear 302 drives the housing 310 to rotate, it is actually tightened from the outer end of the plane dimple spring 306 to store energy. Under the one-way action of the ratchet mechanism 308 , it not only ensures that the force of the energy storage gear 302 continuously tightens the planar dimple spring 306 from the outer end, but also ensures the continuous output of energy from the main shaft 304 .

The energy output mechanism 40 is arranged in the box body 10, and is made up of cylindrical pin disc 402, sun gear 404, planetary gear 406, and eccentric shaft 408, and above-mentioned each part forms little tooth difference internal meshing transmission system (this transmission system is already There is technology, for details, see "Mechanical Design" published by Machinery Industry Press in May 1998, the content of the sixth section on page 222). The main shaft 304 of the energy storage conversion mechanism 30 passes through the cylindrical pin disk 402 and is closely matched with it. When the energy is output from the energy storage conversion mechanism 30 through the main shaft 304, the main shaft 304 drives the cylindrical pin disk 402 to rotate, and the energy is transferred into the energy output The mechanism 40 outputs the power to the generator through the sun gear 404 and the planetary gear 406 after the speed change by the eccentric shaft 408, so as to ensure that the generator obtains sufficient rotational speed.

When the energy input mechanism 20 does work, the energy storage gear 302 drives the housing 310 to rotate as a whole, continuously tightens the planar dimple spring 306 to store energy, and makes the main shaft 304 continuously output energy, thereby driving the cylindrical pin plate 402 tightly matched with it After rotating, the energy is input to the generator from the eccentric shaft 408 after the speed is changed by the planetary transmission system with small tooth difference formed by the sun gear 404 and the planetary gear 406.

When the energy input mechanism 20 does not perform work, the energy storage gear 302 does not rotate, but due to the energy storage of the planar dimple spring 306, the main shaft 304 can be guaranteed to continue to rotate, thereby driving the cylindrical pin disc 402 to rotate, through the internal meshing of the small tooth difference After the transmission system changes speed, it is input to the generator to ensure the continuous operation of the generator.

In addition, the energy output mechanism 40 of the wave power conversion device of the present invention can also adopt transmission methods such as harmonic gear transmission, oscillating pin wheel planetary, etc. to replace the internal meshing transmission system with small tooth difference.
