The invention relates to the technical field of fixed-point ocean observation, in particular to a self-adaptive seabed base which comprises a seabed base box body, a gravity anchor and a release cable, the seabed base box body is connected with the gravity anchor through the release cable, and a controller, a tension sensor, a controlled winch, an acoustic communication machine and a release device are arranged in the seabed base box body; the controller is connected with the tension sensor, the controlled winch, the acoustic communication machine and the releasing device through signal cables. The controller reads data of the tension sensor and controls the controlled winch to adjust the length of the release cable to adapt to the thickness and change of sediment, so that the upper portion of the seabed base box body is suspended in seawater and can receive underwater acoustic signals, the lower portion of the seabed base box body is located in a soft sediment layer, and the seabed base box body cannot be dragged away by the trawl net. The seabed base can be normally recycled, the problem that the length of an existing seabed base release cable cannot adapt to the thickness of sediments at a deployment point, and consequently the seabed base can be lost is solved, and the deployment time and the deployment expenditure are saved.

    本发明涉及定点海洋观测技术领域,具体涉及自适应海床基,其包括海床基箱体、重力锚和释放缆,海床基箱体使用释放缆连接重力锚,海床基箱体内设置控制器、拉力传感器、受控绞车、声学通信机、释放装置;控制器使用信号线缆连接拉力传感器、受控绞车、声学通信机和释放装置;控制器读取拉力传感器数据,控制受控绞车调整释放缆的长度,适应沉积物的厚度及其变化,使海床基箱体上部悬浮在海水中能够收到水声信号且海床基箱体下部位于软沉积物层中海床基箱体不会被拖网拖走,达到海床基能够正常回收的效果,解决了现有的海床基释放缆长度不能适应布防点沉积物厚度可能造成海床基丢失的难题,节省布放时间和布放经费。
