本发明涉及定点海洋观测技术领域,具体涉及漂浮式海床基,其包括海床基箱体及重力锚,海床基箱体与重力锚通过释放缆连接,海床基箱体内设置的隔板上安装有释放装置,隔板将海床基箱体分成上箱体和下箱体,上箱体设置有水声通信机、ADCP、CTD、可选观测仪器和浮球;下箱体设置有带摩擦盘的卷缆装置。在布放过程中,隔板处在软沉积物层和海水的分界面时,释放缆产生的力矩大于卷缆装置摩擦盘的最大静摩擦力矩力矩,卷缆滚筒转动,释放缆变长,避免海床基箱体继续下沉,适应布放点软沉积物层厚度。解决了海床基释放缆太短海床基可能被埋进软沉积物层丢失,太长可能被渔网拖走丢失的技术难题,大幅降低仪器丢失率和单位观测数据成本。

    The invention relates to the technical field of fixed-point ocean observation, and particularly relates to a floating seabed base which comprises a seabed base box body and a gravity anchor. The seabed base box body is connected with the gravity anchor through a release cable, a release device is installed on a partition plate arranged in the seabed base box body, and the partition plate divides the seabed base box body into an upper box body and a lower box body. The upper box body is provided with an underwater acoustic communication machine, an ADCP, a CTD, an optional observation instrument and a floating ball; and the lower box body is provided with a cable winding device with a friction disc. In a releasing process, when the partition plate is located on an interface of the soft sediment layer and seawater, a torque generated by a release cable is larger than the maximum static friction torque of the friction disc of the cable winding device, a cable winding roller rotates, the release cable is lengthened, the seabed base box body is prevented from continuously sinking, and the releasing point soft sediment layer thickness is adapted. Technical problems that the seabed base release cable is too short, the seabed base may be buried in the soft sediment layer to be lost, and the seabed base release cable is too long and may be dragged away by a fishing net to be lost are solved, and an instrument loss rate and unit observation data cost are greatly reduced.
