Description
Technical Field
The utility model belongs to the technical field of ocean energy power generation, and particularly relates to a vibrator power generation device and a power generation system.
Background
With the progress and development of science and technology, people have increasingly increased demand for energy, wherein the consumption of energy is mainly non-renewable energy such as coal, petroleum, natural gas and the like. However, with the continuous decrease of the existing non-renewable energy and the increasing severity of the environmental pollution problem, many countries move the center of energy strategy towards the development of renewable energy. Among the numerous renewable energy sources, ocean energy has significant advantages. The ocean covers about 70% of the earth's surface, with enormous energy content
Huge energy is stored in the ocean, wherein the ocean energy is renewable clean energy with abundant existing forms, and compared with other ocean energy such as wave energy, tidal energy and the like, the change of ocean current energy is more stable and regular. The flow of seawater is generally caused by two factors: firstly, the surface of the seawater is moved by wind blown on the sea surface, and the flow velocity is reduced when the flow on the surface is transferred to the depth direction; the second is that the sea water density difference is caused by the different sea water temperature and salinity in different sea areas, and the flow caused by the sea water density difference is called as density flow. The flow of seawater can generate huge energy, compared with the wind energy storage amount developed and utilized in the world of about 10 hundred million kW, the global ocean current energy is up to 50 hundred million kW, and therefore, the seawater flow energy development device has a good prospect.
Currently, many researchers have actively devoted to the design and development of ocean current energy collecting devices, and particularly, many researchers have studied blade-type ocean current energy power generation devices, and the blade-type ocean current energy power generation devices can be fixed on the sea floor or can be installed at the bottom of a floating body, and the floating body is fixed on the sea through an anchor chain. The power generation principle is similar to that of wind power generation, and almost any wind power generation device can be transformed into a ocean current energy power generation device. The power generation device adopts a wing-shaped blade design, and the blades can rotate under the action of ocean current, so that kinetic energy of the ocean current energy is converted into mechanical energy for rotating the blades, and then the mechanical energy is converted into electric kinetic energy. However, the blade can cause damage to marine organisms in the rotating process, plants such as seaweed and seaweed are easy to wind on the blade, so that the blade type ocean current energy power generation device is high in maintenance cost, high in maintenance difficulty and short in service life, and meanwhile, the starting flow rate of the blade type ocean current energy power generation device is required to be larger than 2m/s, so that ocean current energy cannot be developed and utilized in a large sea area, and the energy conversion efficiency of the ocean current energy is low.
