Technical Field

The embodiment of the invention relates to the field of sea wave power generation and energy storage, in particular to an energy storage and power generation mechanism for lifting sea water by using sea wave fluctuation and tide.

Background

With the acceleration of scientific and technological and modern processes, the demand for energy sources for human beings has increased day by day, resulting in a sharp increase in the consumption of primary energy sources and exhaustion in the near future. Moreover, traditional disposable energy sources such as: the development and use of coal and oil cause great harm to the environment. People turn their eyes to the largest energy base on the earth, the ocean. The sea wave has the great advantages of great reserves, cleanness, no pollution and reproducibility. Wave energy development and utilization studies have been actively conducted in many marine countries since the 70 s of the 20 th century and have made tremendous progress.

In the traditional wave power generation technology, a gear or a piston is driven by the action of waves, and mechanical energy is converted into electric energy through a generator and then input into an external power grid or directly used. The existing sea wave energy storage technology is mainly divided into the following types: 1. the floating box and the piston are driven by the fluctuation fall of the height of the seawater, the piston stores compressed air compressed by compressed air in a shore-based compressed air storage tank, and the compressed air drives a steam turbine to generate power and is conveyed to an external network. 2. The fluctuation drop of the sea water height is utilized to drive the buoyancy tank and the gear rack structure, energy is transmitted to the generator in a mechanical mode, and then electric power is transmitted to the external network. Because of the uncertainty of the size and time of the sea waves, both structures cannot synchronize the stable output power with the external power grid.

The mechanism for lifting seawater by using sea waves can lift seawater to an upstream reservoir at a specified height in a circulating reciprocating manner by using the acting force of the rising and falling of the sea surface on the buoyancy tank and the gravity tank, and then drives a water turbine to generate power by using the huge height drop of the upstream reservoir and the sea surface. The synchronous power supply device is very easy to synchronize with an external power grid and supplies power to the external power grid.
