Description
技术领域technical field
本发明涉及新型能源和电子技术技术领域，特别是涉及一种多节漂浮式波浪能电磁发电机。The invention relates to the technical field of new energy and electronic technology, in particular to a multi-section floating wave energy electromagnetic generator.
背景技术Background technique
近年来，随着科学技术的不断进步和社会经济的高速发展，能源短缺问题日益凸显，并由此而造成的环境恶化逐渐开始影响社会经济发展和人们日常生活。为此，相关的研究人员开始了寻找和开发新型能源的探索，比如太阳能、风能、波浪能等。波浪能是一种分布广泛、储量大、清洁环保、能流密度大的可再生能源，据全球能量委员会调查显示，全球可利用的波浪能达到20亿千瓦，波浪能潜在的能量价值已引起越来越多研究者的关注。In recent years, with the continuous advancement of science and technology and the rapid development of social economy, the problem of energy shortage has become increasingly prominent, and the resulting environmental degradation has gradually begun to affect social and economic development and people's daily life. To this end, relevant researchers have begun to search for and develop new energy sources, such as solar energy, wind energy, and wave energy. Wave energy is a renewable energy source with wide distribution, large reserves, clean environmental protection, and high energy flow density. According to the survey of the Global Energy Council, the global available wave energy has reached 2 billion kilowatts, and the potential energy value of wave energy has attracted more and more attention. attention of more and more researchers.
基于此，目前相继出现了各种波浪能发电技术，其中，提出的波浪能发电技术的原理主要包括：利用物体在波浪作用下的振荡和摇摆运动、利用波浪压力的变化以及利用波浪沿岸爬升时动能与势能的转化等，提出的波浪能发电装置的形式主要有振荡水柱式、浮子式、摆式、鸭式筏式、蚌式等。也有考虑设计如图2公开号CN203702445U的发电装置，其永磁体只有沿竖直方向振动时才可实现线圈切割磁力线发电，也即只有柱状浮筒在波浪的上下浮动作用下才可实现发电，因此发电效率有限，也有考虑设计如图3公开号CN104454307A的发电装置，其是依靠磁流体通过磁化线圈的运动，实现线圈磁通量变化发电的，其也只有在波浪的上下浮动作用下才可实现发电，因此发电效率也有限，也有考虑设计如图4公开号CN100417808C的发电装置，其不但只是在波浪的上下浮动作用下才可实现较好发电，而且其发电是重锤通过滑轮和钢丝绳连接发电机，因此需要在滑轮处会产生能量损耗降低发电效率，因此，研究开发一种结构简单、安装方便、经济可靠的波浪能发电机，对于解决我国的能源短缺问题有着重大的意义。Based on this, various wave energy power generation technologies have emerged one after another. Among them, the principles of the proposed wave energy power generation technology mainly include: using the oscillation and swaying motion of objects under the action of waves, using changes in wave pressure, and using waves when climbing along the coast. The conversion of kinetic energy and potential energy, etc., the proposed forms of wave energy power generation devices mainly include oscillating water column type, float type, pendulum type, duck type raft type, clam type, etc. It is also considered to design a power generation device as shown in Figure 2 Publication No. CN203702445U. Only when the permanent magnet vibrates in the vertical direction can the coil cut the magnetic force line to generate power, that is, only the columnar buoy can realize power generation under the action of the up and down fluctuation of the wave, so the power generation The efficiency is limited, and it is also considered to design a power generation device as shown in Figure 3 Publication No. CN104454307A, which relies on the movement of the magnetic fluid through the magnetized coil to realize the change of the magnetic flux of the coil to generate power, and it can only generate power under the action of the wave's up and down fluctuations. Therefore The power generation efficiency is also limited, and it is also considered to design a power generation device as shown in Publication No. CN100417808C in Figure 4. It not only can realize better power generation under the up and down action of waves, but also its power generation is that the weight is connected to the generator through a pulley and a wire rope, so It is necessary to generate energy loss at the pulley and reduce power generation efficiency. Therefore, research and development of a wave energy generator with simple structure, convenient installation, and economical reliability is of great significance for solving the energy shortage problem in our country.
