technical field

The utility model relates to a wave power generation device, in particular to a swing type wave power generation device which can continuously supply power to observation equipment such as ocean buoys.

Background technique

The environment, energy and population pressure have accelerated the pace of human development of the ocean. In order to ascertain the marine climate, hydrology, fishery and mineral resources, as well as the needs of coastal defense safety, people have deployed a large number of ocean buoys and other observation equipment in the vast ocean. Most of the power energy supply of these observation equipment is completed by rechargeable or disposable batteries, or in the form of solar power generation. Obviously, the above-mentioned existing power supply forms do not have reliability such as continuity and safety. For example, solar power generation will be limited in bad weather. At the same time, solar power generation is also limited when the buoy is working in deeper water, which restricts the realization of deep water seabed detection. On the other hand, there are abundant wave energy resources in the ocean. As a renewable and sustainable form of energy, wave energy has great development prospects, and wave energy power generation technology has also made some progress. The ocean wave energy is not affected by the climate, and there are still wave fluctuations at a certain depth of water. At the same time, there are often internal waves in the depths of the ocean. Therefore, using wave energy to generate power for observation and sensing equipment such as ocean buoys in waves is a kind of Very feasible technical solution.

The utility model designs a buoy device which can continuously supply power by using ocean wave energy, aiming at the power supply requirements of current ocean buoys and other observation equipment. The technical scheme of the utility model can be used as an energy supply module, which can be integrated in the existing ocean buoy observation equipment, so as to realize sustainable power supply to the equipment. Of course, it can also be used as an independent power supply floating body to realize long-distance energy supply between different observation equipment through the connection form of external cables. The utility model is designed aiming at the defects of the prior art scheme, meets the current demand for renewable energy and marine resource development, and thus has good application prospects.

Utility model content

The purpose of the utility model is to provide a power generating device which utilizes wave energy to continuously supply power to observation equipment such as ocean buoys.

This kind of ocean buoy based on wave energy power generation is not affected by climate change and working draft elements, can realize all-weather, all-round and uninterrupted normal work, prolong its service life, and also improve its anti-wind and wave survivability .

When the floating body swings and heaves under the action of waves, the pendulum freely swings back and forth around the rotating shaft, and at the same time drives the rotating shaft to rotate coaxially. At the same time, it can also combine with existing solar buoys to realize a comprehensive system that complements multiple energy sources.

Further, it also includes a storage battery connected to the output end of the rectifier through a circuit, and the output current of the direct current generator can be directly supplied to the measuring and sensing equipment after the direction is adjusted by the rectifier, and the excess electricity can also be charged to the storage battery for backup.

Further, the floating body 1 includes a cylinder body and a top end cover, and is connected to the seabed by a mooring device, and the floating body can swing and heave under the action of waves and work normally.

Further, the pendulum is in a "W" shape, and the pendulum (2) can drive the rotating shaft to realize a 360-degree full-cycle rotation without being affected by sea conditions and mechanism interference.

Further, the bearing is a sealed bearing, which reduces the impact of corrosion and improves the stability and reliability of device operation.

Compared with the prior art, the beneficial effect of the utility model is: the utility model converts the wave energy into the mechanical energy of the pendulum by utilizing the renewable ocean wave energy for energy conversion, and then drives the generator to output electric energy for ocean observation such as buoys.
