Offshore lamp buoy wave current coupling underwater power generation device

Abstract

The invention provides an offshore lamp buoy wave current coupling underwater power generation device. The offshore lamp buoy wave current coupling underwater power generation device comprises a plurality of power generation units which are flexibly connected in series, wherein each power generation unit is buckled on an anchor chain ring through a fixing piece; each power generation unit comprises a Halbach magnet array, a reset spring system, a rectifying, filtering and charging system and two coil winding arrays; the rectifying, filtering and charging systems are arranged between the two coil winding arrays and are horizontally placed at the bottoms of the power generation units; the two coil winding arrays are fixedly distributed on the two sides of the Halbach magnet arrays correspondingly, and the reset spring systems are arranged between the Halbach magnet arrays and the power generation units; and under the action of waves and water flow, anchor chains drive the Halbach arrays in the power generation units to swing left and right in a reciprocating mode to generate alternating current, and direct current is output through rectifying and filtering. According to the offshore lamp buoy wave current coupling underwater power generation device, water surface wave energy and underwater tidal current energy can be collected at the same time, and the problem that a small underwater power generation device is lacked in the field of traditional lamp buoy energy supply is solved.

Description

technical field [0001] The invention relates to the technical field of wave energy power generation, in particular to a wave-current coupled underwater power generation device for a marine light buoy. Background technique [0002] The sea light buoy is a kind of buoy floating on the water surface, which can guide ships and remind them to stay away from shoals and hidden reefs, so as to ensure their safe and convenient navigation. As a visual surface navigation aid, it plays a pivotal role in the safe navigation of ships at sea. As far as the light buoy power supply system is concerned, most of the existing light buoys use traditional solar power and wind power power supply methods. Although this power supply method has the advantages of convenient maintenance, safety, reliability, and low cost, it has the following serious problems: Disadvantages: [0003] (1) Vulnerable to environmental and seasonal influences [0004] The energy collection of the solar power generation ...

AI Technical Summary

Problems solved by technology

[0003](1) Vulnerable to environmental and seasonal influences

[0004]The energy collection of the solar power generation system mainly depends on the sunlight directly irradiating the charging plate, which is greatly affected by the environment, such as continuous cloudy days, foggy days, rainy and snowy days It will greatly interfere with the efficiency of solar power generation. In this environment, solar cells can only output weak currents, and it is difficult to charge large-capacity batteries; wind power generation systems mainly use wind to drive windmill blades to rotate, so that the generator Power generation, which is greatly affected by the season, continuous windless days or windy days will make the wind turbines unable to work normally, and the inability of the light buoys to work will bring major hidden dangers to the safety of the waterway

[0005](2) Low power supply efficiency

[0009]Gear-driven wave energy generation devices generally have multi-stage gears inside, and energy loss will be caused by friction between the gear transmissions. When the device works for a long time After that, the internal gear structure will inevitably deviate, rust, etc., which will lead to a reduction in the transmission efficiency between the gears

[0010](2) Complex structure and difficult maintenance

Although it is entirely possible for a gear-driven wave energy harvesting device to accomplish this arduous task, it is limited by its own internal problems, and its feasibility is still open to question
