The invention discloses a self-destruction device for a disposable detection buoy, and belongs to the technical field of offshore disposable detection buoys. The self-destruction device comprises a self-destruction execution unit, a self-destruction control part and a vacuum pumping structure. The self-destruction execution unit is installed on the lower surface of a hollow floating body shell of the buoy and makes contact with seawater, the self-destruction control component and the vacuum air exhaust structure are installed on the upper surface of the floating body shell, the self-destruction execution unit is connected with the self-destruction control component through a control cable assembly, and the portion making contact with the seawater is only a self-destruction execution unit water permeable hole. Other triggering and executing components are arranged in the buoy body, so that the risk of failure of the triggering mechanism caused by attachment of marine organisms can be avoided; the self-destruction triggering mechanism adopts a mode that a heating resistor fuses a limiting rope, the executing mechanism is a compression energy storage spring, the overall structure is simple and effective, and the machining and manufacturing cost is low; in addition, through the vacuum air extractor, the air pressure in the hollow floating body can be lower than the ambient air pressure, and release of the actuating rod and entering of seawater into the hollow floating body are facilitated.
本发明公开了一种抛弃式探测浮标自毁装置,属于海上抛弃式探测浮标技术领域;其包括自毁执行单元、自毁控制部件以及真空抽气结构。自毁执行单元安装在浮标中空浮体外壳下表面,与海水接触,自毁控制部件和真空抽气结构安装在浮体外壳上表面,自毁执行单元与所述自毁控制部件通过控制电缆组件连接,与海水接触部分仅为自毁执行单元透水孔,其余触发、执行部件均在浮标体内部,可避免海洋生物附着导致触发机构失效的风险;自毁触发机构为发热电阻熔断限位绳的方式,执行机构为压缩储能弹簧,整体结构简单有效,加工制造成本低廉;此外,通过真空抽气装置,可使中空浮体内气压低于环境气压,有利于作动杆释放和海水进入中空浮体。
