Description
Technical Field
The invention belongs to the technical field of ocean wave energy power generation, and particularly relates to a magnetic suspension permanent magnet vibrator type wave energy power generation device.
Background
With the gradual expansion of the functions of the marine observation instrument equipment, the supply demand of the marine observation instrument equipment on electric energy is increased. At present, the power supply modes for the ocean observation platform mainly include four modes: firstly, the power is supplied only by a battery, but the battery is limited in capacity, needs to be replaced manually, is high in cost and is greatly influenced by sea conditions; secondly, solar energy is used for power supply, but the efficiency is lower due to the fact that the solar panel is easy to damage or covered by salt fog, the solar panel is greatly influenced by weather, and the stability is not high; thirdly, wind energy is used for supplying power, but ocean wind power is large, salt mist corrosion is strong, and a wind turbine is easy to damage; and fourthly, power is supplied by utilizing ocean energy, so that the method has the advantages of strong sustainability, high output power and the like, and the current technology is still immature. The wave energy power generation device is based on an ocean observation platform, adopts a wave energy power generation technology to provide electric energy, and has very important application prospect in the field of ocean energy instrument power supply.
Wave energy power generation is based on the existing wave energy research, a wave energy capturing mode, a transmission mechanism, a generator principle and a power conversion technology are effectively integrated, and wave energy in a wide ocean is converted into clean, efficient and electric energy which can be used by users. At present, the wave energy is mainly utilized in three modes, namely an oscillating water column type, an oscillating floater type and a wave crossing type. The oscillating water column type wave energy power generation device and the wave energy power generation device are mainly applied to large-power supply or grid-connected scenes and are not suitable for observation instrument equipment such as ocean buoys and the like with low-power consumption requirements. The oscillating float type wave energy power generation device converts mechanical energy of linear motion and reciprocating motion of a wave energy capturing device into electric energy, and representative devices comprise an AquaBuoy device in Canada, an Archimedes wave pendulum in the Netherlands, a PowerBuoy device in the United states, a CETO device in Australia and the like. In addition, wave energy power generation in a swinging and rotating mode, such as a 'nodding duck' type wave energy power generation device, a pendulum power generation device and the like, is also one of oscillating float type wave energy power generation devices, and is typified by an 'eagle type I' of Guangzhou energy institute of Chinese academy, an Oyster device in England and the like. These devices are also mainly directed to high power demand or grid connection.
Chinese patent CN108678885A discloses a floating wave power generation system based on a magnetic gear speed increasing effect and a design method thereof. The device is characterized in that the relative motion between the inner buoy and the outer buoy of the device enables the cylindrical linear generator to output electric energy along with the fluctuation of waves. The device is used for supplying power to the ocean observation platform, needs to be independent of the observation platform and fixed with the seabed through the anchor chain, and is high in cost and low in electric energy transmission reliability. Chinese patent CN1603610A discloses a floating wave power generation device based on permanent magnet vibrator. The device utilizes its center weight to follow wave motion, drives a plurality of generator permanent magnetism oscillators through wire rope and does reciprocating motion, and then output electric energy, and its volume is great, and pulley and wire rope wearing and tearing are serious, in case meet adverse sea state viability poor. Chinese patent CN108252849A discloses a cylindrical linear generator, a wave energy power generation device and a monitoring method thereof suitable for a mono-pole ocean platform. The device utilizes cylindrical linear generator to generate electricity, needs to be assisted by a single-pile ocean platform, and is limited in application scene.
In conclusion, the high-reliability power supply system of the ocean observation instrument based on the wave energy power generation technology can be optimally designed based on the ocean observation platform and by combining the mature cylindrical linear generator technology, and the application prospect is wide.
