Description
Technical Field
The utility model belongs to the technical field of ocean engineering, a utilize ocean buoy of complementary electricity generation energy supply of solar energy, wind energy and ocean current energy is related to.
Background
The ocean buoy is a widely used ocean hydrological meteorological observation platform, is placed on the sea surface, and is connected with the sea bottom through an anchor chain system. Various observation devices can be carried on the buoy for measuring various meteorological factors (such as wind speed, wave parameters and the like) on the sea. Since the ocean buoy needs to be placed on the sea for a long time, particularly for ocean buoys placed in deep and open sea, the arrangement period can reach several years, and the maintenance cost is high, power supply for various equipment which can be continuously, safely and reliably provided for a long time is an important consideration in buoy design. At present, marine buoy devices that use various renewable energy sources such as solar energy and wind energy in the surrounding environment of the buoy to perform self-power supply are the direction of major attention.
Chinese patent CN211930540U (stone, etc.) proposes a solar power supply device for ocean buoys, which has self-cleaning function and convenient installation, however, due to the intermittent nature of solar power generation, the single solar power supply cannot meet the requirement of long-time observation of buoys.
Chinese patent CN110329436A (land and sea, etc.) proposes a wind-solar complementary power supply buoy, which is equipped with a storage battery for storing generated power, and improves flexibility and stability of the buoy power supply system to some extent, however, wind power generation and solar power generation have gap property, and if the wind power and solar power are insufficient for a long time or some equipment is damaged, a certain problem may still occur in the power supply of the buoy.
In view of the waves of the ocean itself and the abundance of energy contained in ocean currents, researchers have invented a variety of ocean energy powered buoy systems. For example, chinese patents CN207860395U (luasa, etc.) and CN108001626A (luasa, etc.) propose to use the piezoelectric effect generated by wave energy to supply power to buoys; chinese patents CN107288808A (liuyunping, etc.) and CN111422308A (wangxiag, etc.) propose that the magnetic induction wire is cut by the wave pushing coil to generate electricity, so as to supply power to the buoy. However, the above two types of wave energy power generation devices have poor stability in seawater, and the structure is easy to damage.
The ocean current energy is utilized to drive the water turbine to generate electricity, and the ocean current energy power generation device can also be fully utilized even if the ocean current has small flow velocity due to the large density of the seawater. In addition, compared with wind power generation, the speed of ocean current is lower, so that the ocean current energy power generation device is less prone to damage. At present, chinese patents CN205618293U (Rong et al) and CN107401475A (Tu Sai Hu et al) respectively propose devices for generating electricity by ocean currents, but the above two patents are not designed for buoys, and the structural form thereof cannot be applied to ocean buoys.
