Technical field

The invention relates to the technical field of ocean detection, specifically a new type of rotary desilting seabed foundation.

Background technique

The seabed base is a device that works on the seabed. The seabed base is equipped with various detection instruments. After being deployed on the seabed, the instruments conduct long-term continuous observations of the marine environment to obtain long-term comprehensive underwater observation data. The existence of seabed foundation is of great significance to the study of ocean circulation, seafloor seawater flow, and the physical and chemical characteristics of deep seawater.

When the seabed foundation is submerged on the seabed for static detection, due to the existence of ocean currents on the seafloor, it is easy to roll up the sediment on the seafloor and cover the seabed foundation during the flow of seawater. Especially when there is a huge disturbance on the seafloor such as a typhoon, there are many areas on the seabed. The silt buries the seabed foundation. At this time, the seabed foundation cannot receive instructions from the outside to release and float, nor can it break through the silt and float smoothly, making the seabed foundation impossible to recover. After the seabed foundation cannot be recovered, the data cannot be recorded by mobile phones, resulting in the loss of information and property damage. The current anti-siltation effect of the existing seabed foundation is not good. The seabed foundation has no independent desilting ability, and the floating body cannot float when the silt is deep.
