Ocean buoys are widely used worldwide, and can help people to continuously monitor information such as hydrology and weather in a certain sea area. Typically, the ocean buoys need to be positioned in the same relative location to observe long term characteristics of the target sea area.

the first oscillating bar 81 drives the first bevel gear 8 to rotate through the first one-way bearing 80;
the second swing link 91 drives the second bevel gear 9 to rotate through a second one-way bearing 90; the effective rotating directions of the first one-way bearing 80 and the second one-way bearing 90 are opposite, specifically, the inner ring of the first one-way bearing 80 is fixedly connected with the first bevel gear 8, and the outer ring of the first one-way bearing 80 is fixedly connected with the first oscillating bar 81;
the inner ring of the second one-way bearing 90 is fixedly connected with the second bevel gear 9, and the outer ring of the second one-way bearing 90 is fixedly connected with the second swing rod 91.
The working principle of the one-way bearing gear is that when the outer ring of the one-way bearing gear rotates towards an effective direction, the inner ring of the one-way bearing gear also rotates, and when the outer ring of the one-way bearing gear rotates towards an ineffective direction, the inner ring of the one-way bearing gear is separated from the outer ring.

similarly, when the pendulum bob rotates clockwise, the first bevel gear 8 does not rotate, and the second bevel gear 9 rotates clockwise;
in both cases, the main drive bevel gear 2 only rotates in the same direction, so that the bidirectional rotation of the pendulum is converted into the unidirectional rotation of the main drive bevel gear 2, and the energy of the pendulum moving in any direction is transmitted to the generator 5 by the main drive bevel gear 2; therefore, the device can convert the shaft rotation in the opposite direction into the shaft rotation in the fixed direction, and can effectively realize the storage and the utilization of wave energy, so that the buoy loading equipment can work stably for a long time without manually replacing batteries like the traditional equipment, thereby saving a lot of troubles and reducing the cost; secondly, the invention can realize the effect of automatic positioning, and avoid the change of the position of the buoy caused by ocean waves; even, new position coordinates are manually transmitted in the command center, and the device can automatically move to a new position; finally, the pendulum bob with relatively large mass is positioned at the lower part of the device, and the first swing rod 81 and the second swing rod 91 with certain length are adopted to be connected with the corresponding bevel gears, so that compared with the pendulum bob in the prior art, the center of mass of the device is higher, the stability of the device is improved, the moment of the pendulum bob is prolonged, and the output of the driving force of the bevel gears is increased.
