Seabed static sounding penetration device

Abstract

The invention provides a seabed static sounding penetration device which comprises a base frame for supporting the whole device, a probe storage, a traveling mechanism, a manipulator, a ground anchor, a bottom plate, a rotating intermittent mechanism and a hydraulic power source. The bottom plate is fixedly connected to the bottom of the base frame. The probe storage at least comprises a storage frame, a probe, a probe frame and a rotating shaft. The storage frame is fixed on the bottom plate. The rotating shaft and the probe frame are positioned in the storage frame. The probe is placed on the probe frame. The rotating shaft is fixed at the center of the probe frame and can drive the probe frame to rotate, wherein the top end of the rotating shaft is fixed at the top of the storage frame through a rolling bearing; and the bottom end of the rotating shaft is fixed on the bottom plate through a rolling bearing. The seabed static sounding penetration device has compact structure, is simple and convenient to control, is reliable and stable to use, can be used for realizing a sounding process with the maximum cone penetration depth of 15m, is suitable for the seabed static sounding and can also operate on the land.

Description

Technical field [0001] The invention relates to a geological equipment, in particular to a seabed type static penetration penetrating device, belonging to the technical field of seabed penetration. Background technique [0002] After nearly 40 years of development, my country's land static cone penetration technology has mature research results and a large amount of engineering test data, and many technical indicators and key components have been standardized. Compared with the maturity of land static cone penetration technology, the subsea static cone penetration technology started late and developed slowly, and the CPT technology for submarine soil is still blank. At present, there have been few scientific research results in China. The more representative results are the worm gear and gear penetrating submarine static probe developed by the Institute of Oceanology, Chinese Academy of Sciences in 1973; the water area developed by the China Shipbuilding Exploration and Design In...

AI Technical Summary

Problems solved by technology

[0005] The existing submerged penetrating equipment on the seabed adopts a one-rod penetration method (such as the seabed static sounder developed by the Institute of Oceanology, Chinese Academy of Sciences in 1973). Due to the limited length of the probe rod, it not only greatly limits the In addition, the upper part of the probe rod is easily affected by the undercurrent of seawater during the penetration into the seabed, which affects the stability of the whole machine, and even causes test errors and work accidents
