Abstract

The invention discloses a dynamic change original position observation system for a seabed interfacial layer. The dynamic change original position observation system comprises a seabed interfacial layer observation platform, an oscillating type detection rod penetrating apparatus and a multiparameter observation detection rod, wherein the seabed interfacial layer observation platform is used for loading various observation apparatuses and the oscillating type detection rod penetrating apparatus and is in riveted connection with the detection rod penetrating apparatus, the probe of an anti-sinking plate and a through hole are designed to form the laying stability and recovery convenience of an entire observation system, and the oscillating type detection rod penetrating apparatus uses a vibration exciter to generate vertical power to allow the observation detection rod to continuously insert in seabed deposit. New design principle and means are employed, partial liquefaction and strength reduction of seabed deposit can be realized through high frequency vibration, so that the observation detection rod can continuously insert in the seabed deposit, and the implementation is more convenient. The multiparameter observation detection rod is connected with the vibration exciter, and integrated with various sensors to realize synchronous observation of three-phase media of sea water body-seabed interface-seabed deposit. A water inlet fine pipe is provided and a water inlet when opened during recovery can eliminate vacuum suction on the bottom of the detection rod to facilitate recovery. The observation system provides essential technology support for researching dynamic evolution of the seabed interfacial layer.

Description

technical field

[0001] The invention belongs to the technical field of ocean observation, and in particular relates to an in-situ observation system for the dynamic change of the seabed interface layer. Background technique

[0002] The seabed interface layer is the area where the seabed sediments interact with the bottom seawater. The sediments in this layer will undergo complex dynamic responses, and its material composition and structural characteristics are hot issues of common concern in marine science and engineering. Through the in-situ long-term automatic observation of the dynamic change process of the seabed boundary layer, it is important to study the evolution law of the coastal zone, the formation mechanism of geological disasters, the sedimentation dynamics process, the structural characteristics and evolution conditions of the seabed boundary layer, and quantitatively determine the dynamic evolution law of the seabed boundary layer. significance. Long-term in...
