Horizontal-axis ocean current power generation device for underwater vehicle

A horizontal-axis ocean current power generation device for an underwater vehicle, the power generation device being disposed in a groove of a rotary body of the underwater vehicle, wherein the horizontal-axis ocean current power generation device comprises an undercarriage unit, a yawing unit, and a power generation unit;

• wherein the undercarriage unit comprises a retractable tube that is rotatable and has a power source, a first connecting rod, a second connecting rod, and a support post, one end of the retractable tube and one end of the first connecting rod are both rotatably connected to a bottom of the groove of the rotary body of the underwater vehicle, one end of the second connecting rod is rotatably connected to the support post, the other ends of the retractable tube, the first connecting rod and the second connecting rod are rotatably connected together, and the support post has a bottom end rotatably connected to the bottom of the groove of the rotary body of the underwater vehicle and a top end connected to the yawing unit;
• and the first connecting rod is driven to rotate with stretching and retraction of the retractable tube that is rotatable and has the power source, thereby driving the second connecting rod and the support post to rotate;
• wherein the yawing unit comprises a yawing ring gear, a plurality of yawing pinions, yawing driving devices, and a yawing support plate, the plurality of yawing pinions meshes with the yawing ring gear, each of the plurality of yawing pinions is fixedly connected with one of the yawing driving devices, the yawing driving devices are fixed on the yawing support plate, the yawing ring gear is fixed on the support post, and the yawing support plate is rotatably sleeved on the support post and supported by the support post;
• wherein the power generation unit is fixed on the yawing support plate;
• and
• wherein the plurality of yawing pinions rotate relative to the yawing ring gear under the drive of the yawing driving devices, to adjust the power generation unit to actively yaw so as to achieve an incident flow, such that the power generation unit generates electric power in an inflow direction.
