Abstract

The invention discloses a novel rotary de-silting seabed base, comprising a grid seat body, an inner rod, a first drive, a second drive and a float, wherein a casing is mounted above the grid seat body, an inner cavity is formed between the inner wall of the casing and the grid seat body, a sleeve is mounted above the center of the grid seat body, the first drive and the second drive are mounted above the grid seat body, the upper part of the grid seat body is provided with a first metal piece and a second metal piece, an acoustic release is mounted below the grid seat body, the acoustic release is located above a weight cement block, and the float is located inside the inner cavity. In the novel rotary de-silting seabed base, when the lower end of the casing is buried by the sludge, the sleeve rotates on the outer side of the inner rod under the driving of the two drives, and the sleeve moves upwards with the inner rod under the guiding action of the spiral thread, which causes the grid seat body to be gradually separated from the weight cement block, so that the casing is pulled out of the sludge.

Description

technical field [0001] The invention relates to the technical field of marine detection, in particular to a novel rotary desilting seabed foundation. Background technique [0002] 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 observation of the marine environment to obtain long-term underwater comprehensive observation data. The existence of the seabed base is of great significance to the study of ocean circulation, submarine seawater flow, and the physical and chemical characteristics of deep seawater. [0003] When the seabed foundation sinks on the bottom of the sea for static detection, due to the existence of ocean currents on the bottom of the sea, the sediment on the bottom of the seabed is easy to roll up and cover the seabed foundation during the flow of seawater, especially when there is a huge disturbance on the b...
