Title:

SEABED STATIC PENETRATION DEVICE AND PENETRATION METHOD BASED ON MARINE OBSERVATION PROBE ROD

Document Type and Number:

WIPO Patent Application WO/2020/228464

Kind Code:

A1

Abstract:

The present invention relates to the technical field of marine engineering geology and seabed in situ long-term observation. Particularly disclosed are a seabed static penetration device and penetration method based on a marine observation probe rod. The seabed static penetration device based on a marine observation probe rod comprises a probe rod vertical frame, an outer clamp ring and a base, and is characterized in that a probe rod positioning device and a press-cap-type structure are mounted on the outer clamp ring; the base comprises an upper base plate, a lower base plate, and a separation plate arranged between the two; a battery compartment, a driver compartment and an electric motor connected to one another are mounted on the upper base plate, and the electric motor is connected to the press-cap-type structure by means of a driving rope; and correspondingly, a probe rod is fixed between the outer clamp ring and the base in a tight clamping manner. The present invention is rational in structural design, stable in performance, high in working efficiency and small in device size. Not only is stable, vertical and constant-speed penetration of a seabed observation probe rod achieved, but the penetration efficiency is also high, and the penetration depth is large, thereby guaranteeing the quality of seabed observation parameters.
