【摘要】：我國(guó)作為能源消費(fèi)大國(guó),隨著能源形勢(shì)的日益緊張,開發(fā)利用可再生能源成為解決當(dāng)今能源問(wèn)題的重中之重。我國(guó)作為海洋大國(guó),海域遼闊、海岸線漫長(zhǎng),擁有豐富的海洋能資源。波浪能作為海洋能的重要組成部分,是目前國(guó)內(nèi)外海洋研究的熱點(diǎn)。波浪能還可與太陽(yáng)能、風(fēng)能聯(lián)合開發(fā),為偏遠(yuǎn)海島、海洋開發(fā)活動(dòng)提供所需的電力,同時(shí)還可以減少使用化石能源帶來(lái)的經(jīng)濟(jì)和環(huán)境問(wèn)題。目前各類波浪能發(fā)電裝置層出不窮,越浪式波浪發(fā)電裝置具有結(jié)構(gòu)簡(jiǎn)單、建造和維護(hù)方便、整體穩(wěn)定性高的優(yōu)點(diǎn),便于群體化、密集型開發(fā),還可以與海岸線良好的結(jié)合�；谂c防波堤結(jié)合的滑動(dòng)擋板式越浪發(fā)電裝置的結(jié)構(gòu)形式,建立了該裝置的簡(jiǎn)易模型。在波浪水槽中進(jìn)行模型試驗(yàn),研究了正向規(guī)則波入射,不同斜坡高度及不同水深越浪式波浪發(fā)電裝置的受力規(guī)律。采用FLOW-3D軟件進(jìn)行數(shù)值模擬,通過(guò)對(duì)不同波高、不同波浪周期、極端工況進(jìn)行數(shù)值模擬,得出不同波浪要素下斜坡的受力規(guī)律。并通過(guò)數(shù)值模擬,研究了滑動(dòng)擋板式波能發(fā)電裝置越浪斜坡所受波浪力與斜坡比的關(guān)系,通過(guò)對(duì)試驗(yàn)結(jié)果和模擬結(jié)果的對(duì)比分析得出:在波浪入射過(guò)程中傳感器響應(yīng)時(shí)間不同;越浪斜坡在波浪周期作用下所受波浪力的數(shù)值在一定范圍內(nèi)波動(dòng);斜坡在波浪作用下波浪要素條件不變時(shí),斜坡受力與斜坡高度、試驗(yàn)水深有關(guān),呈線性關(guān)系。試驗(yàn)結(jié)果表明斜坡夾角26°至34°之間時(shí),越浪斜坡受力隨著斜坡夾角的增加而減小。研究成果為防波堤兼滑動(dòng)擋板式越浪發(fā)電裝置結(jié)構(gòu)的提供設(shè)計(jì)依據(jù)。
[Abstract]:As a large country of energy consumption, with the increasing tension of energy situation, the development and utilization of renewable energy has become the most important part of solving the energy problems. As a large sea country, China has a vast sea area and a long coastline. As an important part of ocean energy, wave energy is a hot spot of marine research at home and abroad. Wave energy can also be jointly developed with solar and wind energy for remote islands. Ocean development activities provide the electricity needed while reducing the economic and environmental problems associated with the use of fossil energy. At present, various types of wave power generation devices are emerging in an endless stream, and wave-surpassing wave power plants have a simple structure. Easy to build and maintain, high overall stability, easy to group, intensive development, but also can be well combined with the coastline. A simple model of the device was established. The model test was carried out in the wave flume, and the force law of the wave generating device with normal incident wave, different slope height and different water depth was studied. The numerical simulation was carried out by using FLOW-3D software. Through the numerical simulation of different wave heights, different wave periods and extreme working conditions, the force law of slope under different wave elements is obtained. The relationship between the wave force and the slope ratio of a sliding baffle type wave power generator over a wave slope is studied. Through the comparison and analysis of the experimental results and the simulation results, it is concluded that the response time of the sensor is different in the process of wave incident; The value of the wave force on the slope under the action of wave period fluctuates in a certain range, and the force on the slope is related to the height of the slope and the depth of the test water when the conditions of the wave elements are not changed under the action of the wave. The experimental results show that when the slope angle is between 26 擄and 34 擄, the force on the overtopping slope decreases with the increase of the angle of the slope. The research results provide the design basis for the structure of the breakwater and sliding baffle type surpassing power generating device.
