Detailed ways

The specific embodiment of the utility model will be described below in conjunction with the accompanying drawings. As shown in Fig. 1, Fig. 2 and Fig. 3: a bottom-sitting low-center-of-gravity wave energy generating device includes a base 1 as a foundation, and this base 1 is composed of two frames 13 at an angle of 120 degrees. The junction of the two frames 13 is a casing, and a rotatable rotating shaft 3 is arranged inside the casing. This rotating shaft 3 is fixedly connected with the swinging body 2, that is, when the swinging body 2 swings, it can drive the rotating shaft 3 relative to the base. 1 to rotate; the rotating shaft 3 is located at the bottom of the swinging body 2, and a counterweight 11 is arranged at the lower end of the swinging body 2, while a plurality of evenly distributed and equal widths with the swinging frame 10 are arranged in the swinging frame 10 above the rotating shaft 3 The pendulum leaves 12 also leave gaps for seawater to pass between the adjacent pendulum leaves 12, and the cross-sections of all the pendulum leaves 12 are a streamlined drop shape with a large end and a small end. A better thrust effect has been obtained; bevel gears 4 are respectively connected to the two ends of the rotating shaft 3, and each bevel gear 4 is equipped with two one-way bevel gears 5, and the two one-way bevel gears 5 The specific structure is: a one-way bearing is sleeved on the inner ring of an ordinary bevel gear, and the inner ring of the one-way bearing is fixedly connected with the power shaft 6; the power shaft is connected with the transition shaft 7 through a universal coupling, and the transition shaft The other end of 7 is also connected to the input shaft 9 of the generator 8 through a universal joint, while the generator 8 is connected to the battery through a rectifier; in order to improve the overall stability of the base 1, a There are horizontal reinforcing ribs 14 and a plurality of inclined reinforcing ribs 15 are arranged in each frame 13 .

The working process of the bottom-sitting low-center-of-gravity wave energy generating device of the embodiment of the present invention is as follows: the device is placed in the sea, and its placement position needs to ensure that the swinging body 2 can swing along the direction perpendicular to the coastline. When the seawater flows When the swinging body 2, specifically the multiple swing leaves 12 on the swinging body 2 is stressed, the whole swinging body 2 will swing around the rotating shaft 3 and drive the rotating shaft 3 to rotate; when the swinging body 2 rotates When the shaft 3 swings as a shaft, the counterweight 11 at the lower end will swing in the direction opposite to the swing direction of the swing leaf 12, so that when the swing leaf 12 loses the thrust of the water, the swing body 2 can still reverse under the action of the counterweight 11. In this way, the reciprocating rotation of the rotating shaft 3 is finally realized, and when the rotating shaft 3 rotates, the bevel gear 4 provided at the end will also rotate accordingly, and drive the one-way bevel gear 5 meshing with it to rotate; Since only one one-way bevel gear 5 can rotate thereupon during the rotation of the bevel gear 4, the other one-way bevel gear 5 is idling, and these two one-way bevel gears 5 are coaxial again at the same time, so regardless of the bevel gear 4 Which direction to turn, the power shaft 6 will rotate in the same direction, and then realize the uninterrupted and same direction rotation of the transition shaft 7 and the input shaft 9; The transition shaft 7 is connected, so even if the transition shaft 7 is slightly inclined under the action of the sea current, it will not affect the torque input of the input shaft 9; the generator 8 works under the action of the input shaft 9, and the electric energy generated by it passes through the rectifier After rectification, it is input to the storage battery for storage.
