BRIEF DESCRIPTION OF THE DRAWINGS

[0015] In order to more clearly illustrate the technical solutions in the embodiments of the present invention, the following briefly introduces the drawings required for describing the embodiments. Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative work, among which: Figure 1 It is a structural schematic diagram of a preferred embodiment of a ship using wave energy as power according to the present invention. DETAILED DESCRIPTION

[0016] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0017] See also Figure 1 , the embodiment of the present invention includes: like Figure 1The ship shown in the figure uses wave energy as power, including: a hull 1, a sphere 2, a generator, a controller and a battery energy storage module. The sphere 2 is dynamically set at the bottom of the hull 1. In this embodiment, the sphere 2 adopts a hollow sphere structure. The sphere 2 with a hollow sphere structure has a light weight and a large buoyancy in water, which effectively improves the carrying capacity of the hull 1.

[0018] In this embodiment, the hull 1 can be any powered or unpowered ship, as long as the sphere 2 can be installed to capture wave energy.

[0019] The sphere 2 can rotate or swing with the waves to capture the energy of the waves, and the sphere 2 has low resistance underwater and is flexible in rolling, which is conducive to the low-resistance navigation of the ship 1. Arranging several rows of spheres 2 at the bottom of the hull 1 can capture the energy of waves from all directions, has good adaptability, and captures the wave energy to the maximum extent.

[0020] The sphere 2 is directly or indirectly connected to the generator to drive the generator to rotate and generate electricity. In this embodiment, the generator can be arranged inside the sphere 2, inside the hull 1, or at the bottom of the hull, and the selection is flexible. When the generator is arranged inside the hull 1 or at the bottom of the hull 1, it can be connected to the sphere 2 through a flexible transmission shaft to transmit energy to the generator for power generation, and the arrangement is flexible. When the generator is arranged at the bottom of the hull 1, a turbine generator can also be used to make full use of wave energy for power generation.

[0021] When the generator is set at the bottom of the hull 1, the connection with the sphere 2 is simpler, but the generator needs to use corrosion-resistant materials. When the generator is inside the hull 1, the protection of the generator is better, but the connection cost with the sphere 2 is increased, such as using a more complex mechanical shaft or hydraulic system for power transmission, which is slightly less efficient.

[0022] Wave energy is continuous, especially when the ship is constantly encountering waves during sailing, so the energy can be continuously collected through Sphere 2, so that the wave energy can be efficiently converted into electrical energy for onboard systems and electric auxiliary propulsion. The design and power generation system of Sphere 2 have been simulated to ensure the stability of the hull while minimizing the impact on the ship's speed.

[0023] Under the premise of ensuring the stability of the hull and reducing the impact of the ship speed, the dynamic sphere 2 design and power generation system can be verified through the following simulations and experiments: 1. Fluid dynamics simulation: Process: Use CFD tools to simulate the fluid environment of the entire hull (including sphere 2) to evaluate the force of waves on the sphere and the impact of the sphere on the hull, including resistance, lift and hull stability.

[0024] The swinging of the dynamic sphere will generate a certain amount of resistance. CFD simulation can help quantify the impact of this resistance on the ship speed and reduce unnecessary resistance by optimizing the sphere design.

[0025] Results: CFD simulation can provide information on the dynamic characteristics of the hull in waves, stability, resistance distribution, and help optimize the sphere design.

[0026] 2. Structural mechanics simulation: Evaluate the impact of the dynamic sphere 2 and the generator on the structure of the hull in operation to ensure that the rigidity and strength of the hull are sufficient to maintain stability when the system is running; Simulation process: The finite element analysis (FEA) is used to conduct mechanical analysis on the hull and sphere connection structure to ensure that the hull and connection components can withstand external forces and remain stable under wave impact; Evaluate the movement of the ball and the force transfer of the mechanical drive shaft to ensure reliable operation of the generator; The result: The stability of the system under different sea conditions and wave forces can be verified, ensuring that the sphere and the transmission system will not damage the hull structure.

[0027] 3.Simulation of the impact of ship speed: Purpose: To verify the effect of the dynamic sphere on the ship speed and minimize the effect by adjusting the design; Simulation process: simulate dynamic spheres of different sizes, positions and numbers, and evaluate the effect of their motion in waves on the ship speed; Test the balance between wave energy capture efficiency and ship speed. For example, if the sphere is too large, although the energy capture efficiency is high, it will increase resistance and affect the ship speed. Result: Through multiple simulations, the sphere parameters were adjusted to maximize the capture of wave energy without significantly affecting the ship speed.

[0028] 4. Sea condition simulation test Purpose: To verify the performance of the dynamic sphere and generator under different sea conditions through physical testing of scaled-down models; Simulation process: Use wave pool or water tank test to create different wave conditions and observe the working conditions of dynamic sphere and power generation system in real environment. Use these experimental data to verify the accuracy of simulation calculation.

[0029] Result: The stability of the sphere system and the hull was ensured through physical model verification, and the design was further optimized based on experimental data.

[0030] 5. Energy conversion efficiency simulation Objective: To evaluate the energy conversion efficiency of the dynamic sphere and turbine power generation system and determine the amount of electricity that the system can provide under different sea conditions; Simulation process: simulate the motion of the sphere under different wave frequencies, wave heights and wave speeds, calculate and use motor simulation tools (such as MATLAB / Simulink) to simulate the entire energy conversion process, and estimate the efficiency of converting wave energy into electrical energy; Results: Through multiple simulation analyses, we can obtain the energy conversion efficiency curve and understand the power generation capacity of the system under different wave conditions.

[0031] 6. Hull sway and stability analysis Purpose: To analyze whether the dynamic sphere will cause additional sway or instability of the ship in waves.

[0032] Simulation process: Use stability software (such as MAXSURF or ANSYS Aqwa) to analyze the roll, pitch and tilt of the ship under different sea conditions; Evaluate whether the movement of the dynamic sphere will resonate with the swaying of the hull and affect the stability of the hull.

[0033] Result: If the analysis shows significant stability issues, the location, number or design of the spheres may need to be adjusted to improve the stability of the hull.

[0034] The process of wave energy capture needs to cope with challenges of different sea conditions, especially when the wind and waves are too strong, the stability of the dynamic sphere and the durability of the generator are key issues. The sphere 2 can be made of high-strength and lightweight materials, and an adjustable system corresponding to the sphere can be installed on the hull 1, which can adjust the sphere under different sea conditions to ensure the efficiency of wave energy capture.

[0035] The controller is connected between the generator and the battery energy storage module to manage the charging and discharging of the battery energy storage module, and the battery energy storage module is used to power the propulsion system and / or the onboard electrical equipment on the hull 1, which greatly reduces the energy consumption problem. In this embodiment, the controller and the battery energy storage module are arranged in the hull 1, and the controller and the battery energy storage module are protected by the hull 1. The onboard electrical equipment includes lighting equipment and navigation equipment to meet the daily use of electrical equipment on the ship.

[0036] like Figure 1 As shown, the hull 1 is provided with a sail 3, which can fully utilize wind energy to drive the hull 1 and reduce the power consumption of the propulsion system in the hull 1. When the wind is weak, the battery energy storage module is needed to power the propulsion system to ensure the speed of sailing. The use of the sail 3 is conducive to the battery energy storage module to store electrical energy, and the sailing time or distance is extended when the waves are weak.

[0037] The sail 3 on the hull 1 is designed with aerodynamic optimization to reduce air resistance and increase sailing speed. At the same time, the hull 1 can be integrated with a hydrofoil system to lift the hull 1 out of the water during sailing, further reducing sailing resistance.

[0038] In addition, the hull 1 is provided with solar panels, which are connected to the battery energy storage module through the controller, and use solar energy to generate electricity and store energy, forming a wind energy, solar energy and wave energy hybrid power system, achieving zero-emission navigation, and meeting the global trend of marine environmental protection. Especially in calm weather, the solar panels can provide stable power supply for the ship and improve the adaptability of the ship.

[0039] In summary, the present invention points out a ship that uses wave energy as power, realizes the utilization of wave energy, drives the movement of the sphere through wave energy, drives the power generation of the generator, and uses the battery energy storage module to store electricity, which meets the electricity consumption of the propulsion system and the electrical equipment on board, has good energy saving performance, and is particularly suitable for the navigation of sailboats.
