A Seabed Static Penetration Equipment Based on Rotary Power Head

Abstract

The invention relates to the field of marine engineering technical equipment, in particular to a seabed static penetrating equipment based on a rotary power head. Including the overall frame, the bottom of the overall frame is provided with a probe rod frame, a second support frame is provided next to the probe rod frame, a horizontal support plate is provided on the second support frame, and two vertical hydraulic cylinders are provided on the lower end of the support plate , the telescopic rod of the hydraulic cylinder is connected to both ends of the horizontal plate, and the board is fixed with a holding cylinder; there are two hydraulic cylinders on the top of the overall frame, the telescopic rod of the hydraulic cylinder is connected with the horizontal support plate, and the bottom end of the transmission shaft of the hydraulic rotary transmission mechanism Connected with the two-way oil cylinder, there is an oil circuit inside the hydraulic rotary transmission mechanism, which communicates with the oil circuit of the two-way oil cylinder. Both piston rods of the two-way oil cylinder are connected to clamping blocks, and the two clamping blocks are used to clamp the probe rod. Compared with the problem of radial instability and inconvenient operation of the full-length straight rigid probe rod in the deep sea environment, the present invention adopts the segmented probe rod and has better stability.

Description

technical field [0001] The invention relates to the field of marine engineering technical equipment, in particular to a seabed static penetrating equipment based on a rotary power head. Background technique [0002] Domestically, in recent years, the emphasis on the development of marine resources has been gradually increased, and the investment in marine engineering construction has been increasing. Before the construction of submarine engineering, the investigation and research on the properties of the submarine soil is an indispensable first step. The study of sediment properties from 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 efficient survey and scientific analysis of the mechanical properties of the seabed strata can carry out safe and economical foundation design of marine engineering structures. [0003] Submarine soil is...

AI Technical Summary

Problems solved by technology

[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, resulting in radial instability and inconvenient operation, so it is not suitable for the exploration of deep seabed sediments; The method of section probe rod requires manual docking, which requires a large amount of labor. This detection method is only limited to shallow water operating environments and is not suitable for deeper sea areas.
