Title:
SEABED-TYPE STATIC CONE PENETRATION SYSTEM AND METHOD BASED ON SEAFLOOR TEMPLATE
Document Type and Number:
WIPO Patent Application WO/2024/021688
Kind Code:
A1
Abstract:
The present invention relates to the technical field of marine downhole static cone penetration, in particular to a seabed-type static cone penetration device and method based on a seafloor template. A system comprises a water control unit, an underwater control unit and a data transmission system. The underwater control unit comprises a photoelectric measurement and control cabin and a static coning system, wherein the static coning system comprises a static cone penetration probe connected to the photoelectric measurement and control cabin. In the present invention, a dual-motor mechanism is used, a probing rod can be clamped by means of dual motors, and the probing rod is driven, by means of the operation of the dual motors, to perform penetration or withdrawal. In this way, by means of the rotation of the motors, the probing rod is driven to perform penetration and withdrawal; moreover, not only can the effect of coning at a constant speed be achieved, but the situation in which coning data is discontinuous due to a frequency of coning and withdrawal as high as that in the prior art is also avoided. Moreover, by using the arrangement of the dual-motor mechanism, position offset of the probing rod can be avoided.
