Seabed static sounding counter-force device

Abstract

The invention provides a seabed static sounding counter-force device. The seabed static sounding counter-force device comprises a waterproof part formed by a waterproof shell and a leveling supporting part, the leveling supporting part is arranged below the waterproof part, the waterproof part is divided into a first waterproof cavity and a second waterproof cavity by an upper connecting plate, a counter-force device for driving a probe rod to move is arranged in the second waterproof cavity, the first waterproof cavity is internally provided with a rotary disc structure used for containing probe rods, a picking mechanism used for grabbing the probe rods from the rotary disc structure and a rod body splicing mechanism used for achieving splicing of the multiple probe rods, the counter-force device clamps and drives the probe rods to conduct static sounding on underwater gravel, the bottom of the waterproof part is provided with multiple inclination angle measuring devices, the inclination angle measuring devices are in signal connection with a main control unit, and the main control unit is further in signal connection with the counter-force device, the leveling supporting part, an air pump, a first rotating motor, the picking mechanism and the rod body splicing mechanism.

Description

technical field [0001] The invention relates to the technical field of marine exploration, in particular to a seabed static penetrating force counterforce device. Background technique [0002] In recent years, the pace of marine resource development has been accelerating, and the number of marine engineering constructions has increased. The investigation and research on the properties of seabed soil is an essential part of marine engineering construction. The study of sediment properties within several meters to tens of meters below the seabed is of great significance for marine environmental investigation, seabed resource exploration, marine development and utilization, etc. The safe and economical foundation design of marine engineering structures mainly depends on the efficient survey and scientific analysis of the mechanical properties of the seabed formation. [0003] The seabed static penetration method is an in-situ measurement method of seabed soil with simple opera...

AI Technical Summary

Problems solved by technology

Staying the static penetrating probe in the soil to be tested can make long-term observations of the seabed soil, especially to test the physical and mechanical properties of the seabed soil under the action of waves, while drilling, sampling and other operations cannot achieve such long-term observations result

[0004] At present, most of the static penetration testing equipment uses a straight and rigid probe rod of the entire length to directly press the probe into the seabed surface, and the current static penetration testing equipment has a low degree of automation and a relatively single function. The method of segmented probe rods cannot realize the functions of underwater leveling and automatic rod extension at the same time, which requires a large amount of labor.
