The power generation device of this project includes a shell, suspension body, internal support, etc. The shell is a closed inner cavity, and the suspension body and internal support are set in the inner cavity. The suspension body is a heavy object made of cast iron. When in use, the power generation device is placed on the sea surface, and the shell moves up and down with the waves. The suspended weight in the inner cavity, due to the principle of inertia, moves in reverse relative to the shell, generating kinetic energy. Mainly used for island power generation, offshore engineering power supply, ocean going ships and vessels power supply, seawater desalination, deep-sea aquaculture power supply, etc.

Core technology

Calculation of suspended body momentum

Determine the optimal weight of the suspended body based on the specific wave characteristics and momentum curve in the designated marine area, as well as the rated power generation requirements.

Super Suspension System

By utilizing the formula for elastic modulus to derive sensitivity calculation methods, we have implemented a highly sensitive suspension system using an original spring structure.

Selection of special materials

Selecting polymer composite materials to prevent seawater corrosion, while greatly reducing overall weight, improving energy efficiency, and reducing costs.

Bidirectional power output technology

Transfer energy from the power supply to the load in one direction, and reverse the energy from the load back to the power supply for energy recovery.

Elastic energy storage technology

Develop a dynamic energy storage structure to achieve smooth curve performance of the generator's working torque within a single wave cycle.

Motion constraint and compensation technology

Including steps such as sensor data collection and processing, control algorithm design and implementation. Improve the motion accuracy, stability, and reliability of the system through effective constraints and error compensation.

Core Advantages

High Efficiency

Using a special built-in "inertial kinetic energy trans-oscillation" patented technology, kinetic energy capture efficiency is much higher than the traditional technology; The minimum wave response amplitude is 20cm, and 40cm high waves can generate electricity normally and achieve commercialization.

Small size

The single size is small and lightweight, the weight of 5kW equipment is only 4000kg, the same power, the volume and weight is only about 10% of the traditional technical equipment, easy to transport and put.

Safe and stable

With a unique motion constraint design, it can effectively resist the impact of large waves, and can still generate electricity under large wave conditions, which can be applied to the global wave height area and easy to export.

Anti-corrosion

All the mechanical structure and mechanical action are in the sealed box, isolated from the sea water, there is no seawater corrosion, the main body of the equipment floating in the sea, only and the seabed flexible connection, no anchoring, no fixed base, greatly reducing the installation cost.

Simplify the industrial chain

For large-scale power supply needs, the standard equipment of 5kW can be used for interconnection, and the distributed grid layout can realize the maximum megawatt wave energy power station. The raw materials required for product production are conventional motors, steel and cables, and the industrial chain is simple.
