[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.
