detailed description

In order to make the purpose, technical solutions and advantages of the embodiments of the utility model more clear, the technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the utility model. Obviously, the described The embodiments are some embodiments of the present utility model, but not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

As shown in Figures 1 to 2, the wave energy generating device is composed of a screw 1, a thrust bearing 2, a ratchet 3, a gear 4, a connecting shaft 5, a generator 6, a fixed column 7 and a floating body 8, the thrust bearing 2, the ratchet 3 And gear 4 is arranged in the floating body 8. The screw 1 is set on the fixed column 7, the floating body 8 is set on the screw 1, the generator 6 is connected with the gear 4 through the connecting shaft 5, the screw 1 is provided with a thrust bearing 2, the ratchet 3 is fixed on the thrust bearing 2, and the ratchet 3 Mesh with gear 4. The fixed column 7 is an offshore platform, a tower structure or a fixed device along the coast.

The working principle of the wave energy power generation device is to use the up and down movement of wave energy to drive the floating body 8 to move up and down along the screw 1 to realize the rotation of the ratchet 3 . When the floating body 8 moves upward along the screw 1, the screw 1 converts the upward force on the floating body 8 into the horizontal rotation force of the ratchet 3, so that the ratchet 3 rotates around the screw 1, and the ratchet 3 drives the gear 4 and the connecting shaft 5 Rotate, the connecting shaft 5 drives the generator 6 to work. When the floating body 8 moves downward, due to the particularity of the ratchet 3 mechanism, the outer shaft gear can continue to rotate in the same direction under the action of inertia, and the downward force of the floating body 8 will not be transmitted to the rotating shaft, which can ensure Continuous mechanical energy output, which can make the output of wave energy more stable. The wave energy generation device converts mechanical energy into electrical energy. Since the wave energy generation device utilizes the characteristics of wave undulations, if the material strength and other factors permit, the wave energy generation device can withstand a wide range of wave levels. In harsh sea conditions It can also be used normally under the environment, continuously converting wave energy into electrical energy.

The core component of the wave energy generation device is the screw 1, which is different from the conventional screw. There is no self-locking in the wave energy generation device. The upward force of the floating body 8 is converted into a rotational torque through the screw 1, thereby driving the generator 6 to generate electricity. When selecting the pitch of the screw 1, since the value of the pitch needs to be outside the self-locking range, and within a reasonable range, the larger the pitch, the greater the rotational torque, and the rationality of the pitch selection has an impact on the efficiency of wave energy use. greater impact.

The wave energy power generation device of the utility model utilizes the ups and downs of sea waves to drive the floating body 8 to move up and down along the screw rod 1, so that the upward force received by the floating body 8 is transformed into the horizontal rotational force of the ratchet 3, and the ratchet 3 rotates and drives the gear 4, The connecting shaft 5 rotates to drive the generator 6 to generate electricity. The utilization rate of wave energy is high, and the generating power of the generator 6 is large, and the wave energy is converted into electric energy, which is green and environmentally friendly.
