【摘要】：海洋剖面探测浮标可以测量水下不同深度的温度、压力、盐度等数据，通过通讯卫星传回地面，为海洋开发与研究、灾害预报和海上军事活动提供海洋环境参数，因此得到了广泛的应用。传统的海洋剖面探测浮标采用锂电池供电，浮标携带的电池数量限制了浮标的工作寿命。由于浮标投放位置远，工作位置不固定，电池耗尽了不再回收，因此需要不断投放新的海洋剖面探测浮标，耗资巨大。为了延长浮标的工作寿命，提高浮标的工作能力，本文设计了一种利用海洋温差能供能的剖面探测浮标，该浮标利用相变材料吸收海洋温差能并储存在蓄能器中，然后释放能量驱动浮标上浮下潜，并产生电量储存在电池中为浮标的控制系统和测量设备供电。针对该装置的设计过程，本文主要做了以下研究工作： 1．通过对温差能驱动水下滑翔机工作过程和海洋温差能发电装置工作原理的整合，设计了既能驱动浮标上浮下潜又能够发电的工作循环。分析了浮标水下运动过程，为浮标的控制提供了依据。 2．对相变过程进行了研究，对比了气 液相变过程和固 液相变过程，选择固 液相变为本平台的工作方式。对相变材料的性能进行了试验研究，掌握了其性能。对相变材料的相变传热过程进行了分析和求解。并研究了浮标的热力学过程，，计算了热力学效率。 3．建立了浮标动力系统发电过程和正、负浮力调节过程的数学模型，进行了仿真计算，确定了浮标的各部件的参数，搭建了原理样机，测试了其工作性能，与理论计算结果进行了对比。最后对浮标的机械结构与控制系统进行了初步设计。
[Abstract]:Ocean profile buoys can measure temperature, pressure, salinity and other data at different depths under water, and send them back to the ground through communications satellites to provide marine environmental parameters for marine development and research, disaster forecasting and military activities at sea. Therefore, it has been widely used. The traditional marine profiling buoy is powered by lithium battery. The number of batteries carried by the buoy limits the working life of the buoy. Because the buoy is far away, the working position is not fixed, and the battery is exhausted and no longer recovered, it is necessary to continuously drop new ocean profile detection buoys, which is very expensive. In order to prolong the working life of the buoy and improve the working ability of the buoy, a section detection buoy using ocean temperature difference energy supply is designed in this paper. The buoy absorbs the ocean temperature difference energy and stores it in the accumulator by using phase change material. It then releases energy to drive the buoy up and down and generates electricity stored in the battery to power the buoy's control system and measuring equipment. According to the design process of the device, this paper mainly does the following research work: 1. Through the integration of the working process of underwater glider driven by temperature difference energy and the working principle of ocean thermoelectric power generation device, The working cycle which can drive buoy up and down and generate electricity is designed. The underwater motion process of the buoy is analyzed, which provides the basis for the control of the buoy. 2. The phase transition process is studied, and the gas-liquid phase change process and the solid-liquid phase change process are compared. Select solid liquid phase to work on this platform. The properties of phase change materials are studied experimentally and their properties are mastered. The phase change heat transfer process of phase change material is analyzed and solved. The thermodynamic process of the buoy is studied and the thermodynamic efficiency is calculated. 3. The mathematical models of the power generation process and the positive and negative buoyancy regulation processes of the buoy power system are established and simulated. The parameters of each component of the buoy are determined, the principle prototype is built, its working performance is tested, and the results are compared with the theoretical calculation results. Finally, the mechanical structure and control system of the buoy are preliminarily designed.
