Combined floating block type wave power generation system

Abstract

The invention discloses a combined-floating-block-type sea wave power generation system. The combined-floating-block-type sea wave power generation system comprises at least two floating blocks. The floating blocks are connected with a sliding rail on a cabin through a power rod in a sliding mode. The power rod is supported by a platform. The inner lateral side of the power rod is provided with teeth, and the inner lateral side is provided with a rack structure. An output gear of a speed-changing gear box is connected with a generator through a transmission shaft. When sea waves rise or drop, single-direction rotating of the transmission shaft is achieved through transmission accelerating of the rack structure and the speed-changing gear box, and therefore power is generated by the generator. The floating blocks are evenly distributed on the peripheral surface of the cabin, the cabin is fixedly supported on the platform, the upper portion of the cabin is covered and closed by a cover top, and the platform is provided with a foundation pile. The combined-floating-block-type sea wave power generation system improves sea wave use ratios, reduces energy consumption from the kinetic energy to the electric energy of the sea waves, and improves the efficiency of the generator.

However, due to the intermittent, random, and unstable characteristics of ocean waves, the research on ocean wave power generation technology is still being gradually explored.

[0003] The common wave power generation device is an oscillating air column type or a wave-gathering energy storage type. Among them, the oscillating air column type needs to transfer the energy of the up and down movement of the ocean waves to the air to form an oscillating air column, and then the oscillating air column The energy of the column is transmitted to the power generation equipment for power generation. The disadvantage of the oscillating gas column power generation device is that the device is generally installed on the shore or on the shore, the applied wave energy is low, the power generation efficiency is low, and due to the large noise, it must be far away from residential areas. Second, in the process of transferring the energy of the ocean waves to the air, the friction between the air and the pipe wall, the compression and expansion of the circular pipe will all produce a large energy loss; in addition, an additional design is required to convert the reciprocating airflow into a directional movement Straightening equipment, or use impellers with lower conversion efficiency

The wave-gathering energy storage power generation device requires special terrain, and can only use the energy of the crest of the wave, and the utilization rate of wave energy is low.

The above two types of wave power generation devices have the same defect, that is, they cannot cope with the undulating characteristics of wave motion, and offsets are likely to occur between adjacent waves with different high and low fluctuations, which reduces the utilization rate of wave energy of the device
