Seafloor static penetration device based on ocean observation probe rod and penetration method of seafloor static penetration device

Abstract

The invention relates to the technical field of marine engineering geology and seafloor in-situ long-term observation, and particularly discloses a seafloor static penetration device based on an oceanobservation probe rod and a penetration method of the seafloor static penetration device. The seafloor static penetration device based on the ocean observation probe rod comprises a probe rod vertical frame, an outer clamping ring and a base, and is characterized in that a probe rod positioning device and a pressing cap type structure are installed on the outer clamping ring, the base comprises an upper bottom plate, a lower bottom plate and a separation plate located between the upper bottom plate and the lower bottom plate, a battery bin, a driver bin and a motor which are connected with one another are installed on the upper bottom plate, the motor is connected with the pressing cap type structure through a driving rope, and the probe rod is correspondingly clamped and fixed between the outer clamping ring and the base. According to the seafloor static penetration device based on the ocean observation probe rod and the penetration method of the seafloor static penetration device, structure design is reasonable, the performance is stable, the working efficiency is high, the size of the seafloor static penetration device is small, stable and vertical penetration with the constantspeed of the seafloor observation probe rod is realized, the penetration efficiency is high, the penetration depth is large, and the quality of seafloor observation parameters is guaranteed.

Description

[0001] (1) Technical field [0002] The invention relates to the technical field of marine engineering geology and seabed in-situ long-term observation, in particular to a seabed static penetrating device and a penetrating method based on a marine observation probe rod. [0003] (2) Background technology [0004] With the development of society and economy, the country's demand for mineral resources and energy continues to increase, and it begins to seek wealth from the ocean on a large scale. More and more offshore engineering structures are put into use, and ocean development has entered a new stage of development. Obtaining various physical and mechanical properties of seabed sediments, analyzing factors affecting the stability of seabed sediments, and determining unstable areas and potential geological structures are of great significance to the safety of marine engineering construction and have become a research hotspot at this stage. Among them, the seabed observation pro...
