摘　　要：为实现海洋纵深垂直温度场分布的定点实时监测,研究了光纤测温传感技术和太阳能技术,设计了一种新型海洋测温浮筒。根据海洋工作环境对浮筒提出的浮力、抗倾覆性、强度以及密封性要求,建立了浮筒的几何模型。通过等效转换,建立浮筒在波浪力作用下的数学模型。并通过仿真实验,验证了浮筒的极限倾覆波幅及浮筒结构的可行性。提出的三浮腔测温浮筒能够测量海洋垂直纵深温度分布,浮力满足安全系数要求,具有较好的抗倾覆性和结构强度,可在海洋中稳定长时间工作。In order to monitor the deep ocean vertical temperature distribution at fixed-point,this pa- per studies the fiber optic temperature sensing technology and solar technology and designs a new type of o- cean temperature floats.According to the requirements of float＇s buoyancy,overturning resistance,strength and sealing, afloat geometry model is established.Through the equivalent conversion, the float＇s mathematical model in the waves force is established.And through simulation experiment to test the limits of overturning wave amplitude in line with the requirements ,it is proved that the structure of this float is feasible. Three floating chamber temperature buoys which are capable of measuring ocean vertical depth temperature distribution,with their buoyancy meeting the safety requirements ,have good resistance to overturning and structural strength,being able to work stably long time in the ocean.
