Problems solved by technology

There are many types of leveling devices. For large offshore platform leveling ships with lifting legs, the elevation of the bottom surface of the scraper is usually calculated by GPS and inclinometers. However, this type of platform leveling ship is expensive and complicated to operate. Generally, they are customized for special projects, with poor versatility, and there is a high risk of plugging and pulling piles
The inclinometer only reflects the inclination angle at its installation location, and cannot obtain the overall inclination situation
For the underwater simple frame leveling frame, due to the different lifting heights of the hydraulic outriggers and the rigidity of the structure, there is a certain degree of deformation, and it is difficult to use GPS and inclinometers to calculate the accurate height of the scraper.

Abstract

The invention discloses a bottom self-elevating underwater leveling frame monitoring and adjustment system, which includes 4 underwater pressure sensors, a positioning GPS, a data sending unit, a temperature, salt and depth instrument, and data processing and display Module, 4 underwater pressure sensors are respectively installed on the rectangular frame of the leveling frame near the 4 hydraulic outriggers, the positioning GPS and data sending unit are exposed to the water surface, installed on the measurement tower, and the measurement tower is fixed on the leveling frame On the rectangular frame, the temperature, salt and depth instrument is installed on the hopper or trolley of the leveling frame; the data processing and display module includes a computer, a data receiving unit and a data processing unit, and the data processing unit obtains the expansion and contraction of the four hydraulic legs through calculation. The invention can obtain the stretching amount of the four hydraulic legs of the leveling frame, and send the stretching amount to the hydraulic control system to realize the height adjustment of the hydraulic legs.

Description

technical field [0001] The invention relates to a leveling frame monitoring and adjustment system, in particular to a bottom self-elevating underwater leveling frame monitoring and adjustment system. Background technique [0002] At present, more and more water transportation projects need to carry out the leveling work of the underwater foundation bed, such as port docks, revetment dams, immersed tube tunnels and other projects. There are many types of leveling devices. For large offshore platform leveling ships with lifting legs, the elevation of the bottom surface of the scraper is usually calculated by GPS and inclinometers. However, this type of platform leveling ship is expensive and complicated to operate. Generally, they are customized for special projects, with poor versatility, and there is a high risk in plugging and pulling out piles. The inclinometer only reflects the inclination angle at its installation location, and cannot obtain the overall inclination situ...
