AI Technical Summary

Problems solved by technology

At present, although there are many types of wave energy research and development equipment in my country, the pertinence is not high. The capacity of a single machine is small and the array layout lacks compatibility. The equipment for deep seas has poor adaptability to high sea conditions and water depth.

Embodiment Construction

[0049] The specific embodiments of the method and device for collecting wave energy involved in the present invention will be described in detail below in conjunction with the accompanying drawings.

[0050]

[0051] In this embodiment, the flow channel is 20 cm wide, 50 cm long, the water depth is 2 cm, and the incident water wave frequency is 14 Hz.

[0052] Such as figure 1 As shown, the method for gathering wave energy provided by this embodiment comprises the following steps:

[0053] Step 1. Determine the layout of the underwater energy-gathering structure according to the wave energy collection water area:

[0054] In this embodiment, in order to eliminate the influence of the two side walls on the wave propagation, the middle area of ​​the flow channel is selected as the wave energy collection water area, the horizontal span L=12cm, and an underwater energy gathering structure (as an underwater energy gathering device) can be set. .

[0055] Step 2. Determine the ...

Abstract

The present invention provides a method and device for gathering wave energy. The method includes: Step 1. Determine the layout of the underwater energy-gathering structure according to the wave energy collection water area; Step 2. Determine the bottom surface radius R of the underwater energy-gathering structure; Step 3 .To determine the shape of the underwater energy-gathering structure, the busbar equation is: set the number and distribution of data points controlled by the shape of the structural busbar, draw the busbar curve according to the coordinate values ​​of the data points, and rotate the busbar curve 360° around the central axis to obtain the water Underwater energy gathering structure; step 4. Set up underwater energy gathering structure: make an underwater energy gathering structure based on the data in step 3, and then place the underwater energy gathering structure at the energy collection point of the wave energy collection water area according to the layout method in step 1 At the front face, gather wave energy to collect wave energy in the water area.

Description

technical field [0001] The invention belongs to the technical field of water conservancy science and marine engineering, and in particular relates to a method and a device for gathering wave energy. [0002] technical background [0003] Wave energy is a renewable energy that exists in the ocean. It is considered to be one of the most promising green energy sources because of its advantages of no pollution, large reserves, and wide distribution. Wave energy is more spatially concentrated than both wind and solar energy, and it is more durable and predictable than wind energy. It is estimated that the global wave energy resource is at least 1TW, and the potential annual energy production is about 2000TW, which is equivalent to the energy of nuclear or hydroelectric power. At present, the utilization of wave energy is concentrated in wave energy power generation, carrying sediment, guiding sewage and so on. Wave power generation is the main way of developing wave energy. In ...
