Description

Technical Field

[0001] This invention relates to the field of water surface wave technology, and in particular to a method for amplifying water surface wave height, a device and method for utilizing wave energy. Background Technology

[0002] In the design and operation of floating hulls, waves are generally considered a harmful factor. During the design process, wave load analysis is performed using wave observation data to obtain the wave distribution around the floating hull and the load distribution of the floating beams. This information is then used as a basis for structural design or reinforcement. For example, this applies to the structural design or reinforcement of ships.

[0003] Wave energy is an abundant energy source. For ships or platform facilities that operate on water for extended periods, utilizing wave energy can significantly reduce dependence on energy replenishment, thereby lowering operating costs for all parties involved.

[0004] Current technologies for utilizing waves focus primarily on creating and improving wave-utilizing equipment, with limited research on the waves themselves. Furthermore, the utilization efficiency of common valley waves is low, significantly impacting the return on investment and limiting the development of wave-related technologies.

[0005] Therefore, it is necessary to develop a new method for amplifying water surface wave height, a wave energy utilization device and method, in order to improve some of the problems existing in the prior art. Summary of the Invention

[0006] The purpose of this invention is to overcome the defects of the prior art by providing a method for amplifying water surface wave height, a device and method for utilizing wave energy.

[0007] The objective of this invention can be achieved through the following technical solutions:

[0008] This invention provides a method for amplifying water surface wave height, applicable to water bodies, comprising the following steps:

[0009] Waves are formed on the surface of the water body;

[0010] Floating bodies are spaced apart on the surface of the water body. The floating bodies include a first floating body and a second floating body. The length H of the first floating body satisfies 150≤H≤350 meters, and the length h of the second floating body satisfies 60≤h≤200 meters.

[0011] Adjust the distance between the first float and the second float so that the distance G satisfies 3≤G≤20 meters.

[0012] Compared with existing technologies, the water surface wave height amplification method provided by the present invention, by setting floating bodies at intervals on the surface of water bodies with waves, and by adjusting the period of the waves, the length of the floating bodies, and the spacing between the floating bodies, makes the period T satisfy 5≤T≤9 seconds, the length H of the first floating body satisfy 150≤H≤350 meters, the length h of the second floating body satisfy 60≤h≤200 meters, and the spacing G satisfy 3≤G≤20 meters, thereby amplifying the wave motion entering the gap between the first and second floating bodies, achieving a resonant period, and amplifying the height of waves with a period of 6 to 8 seconds, which is beneficial to improving the efficiency of wave utilization.

[0013] Optionally, the period T satisfies 6 ≤ T ≤ 8 seconds.

[0014] Optionally, the length H of the first float satisfies 200≤H≤280 meters, and the length h of the second float satisfies 60≤h≤100 meters.

[0015] Optionally, the length ratio i of the first float and the second float satisfies 2.5≤i≤3.5.

[0016] Optionally, the first float and the second float are arranged in parallel.

[0017] Optionally, the first float and the second float are symmetrical about the same axis in the length direction.

[0018] Optionally, the width of the float gradually decreases as it extends from its central region to both ends. The width of the tail ends of the float is smaller than that of the central region, causing the gap to further narrow near the central region. As the gap narrows, the waves entering between adjacent floats amplify further near the central region, thereby further improving wave utilization efficiency.

[0019] This invention provides a wave energy utilization device, comprising:

[0020] Floating body and energy harvesting mechanism;

[0021] The floating body includes a first floating body and a second floating body, which are spaced apart and disposed on the surface of the water body with waves.

[0022] The energy harvesting mechanism is disposed between the first float and the second float, and is used to harvest energy from the waves between the first float and the second float;

[0023] Wherein, the wave period T satisfies 5≤T≤9 seconds, the length H of the first float satisfies 150≤H≤350 meters, the length h of the second float satisfies 60≤h≤200 meters, and the distance G between the first float and the second float satisfies 3≤G≤20 meters.

[0024] Compared with existing technologies, the wave energy utilization device provided by this invention, by setting floating bodies at intervals on the surface of water bodies where waves are formed, and then setting an energy harvesting mechanism in the gap between the floating bodies, ensures that the length H of the first floating body satisfies 150≤H≤350 meters, the length h of the second floating body satisfies 60≤h≤200 meters, and the gap G satisfies 3≤G≤20 meters. This amplifies the wave motion entering the gap between the first and second floating bodies, and achieves a resonance period when the wave period T satisfies 5≤T≤9 seconds, thus amplifying the wave height. The energy harvesting mechanism then harvests energy from the amplified wave height, improving the efficiency of wave utilization.

[0025] This invention provides a wave energy utilization method. Using the aforementioned wave energy utilization device, the height of the wave is first magnified, and then energy is harvested from the wave with the magnified wave height, thereby improving the efficiency of wave utilization.
