Suction penetration control system

Abstract

The invention discloses a suction penetration control system, which is used for controlling operating conditions of a bucket foundation (21) and comprises a detector (22), a controller (23) and an actuator (24). The detector (22) is used for detecting the conditions of the bucket foundation (21) to obtain detection signals. The controller (23) is used for receiving the detection signals and comparing the detection signals to pre-stored control targets. When the detection signals meet the control targets, the controller (23) transmits action commands to the corresponding actuator (24). The actuator (24) changes in operating modes according to the action commands. By means of the suction penetration control system, the conditions of the bucket foundation can be detected in real time, and the conditions of the bucket foundation can be controlled, so that full automatic control is realized, control accuracy is guaranteed, and construction quality is improved.

Description

technical field [0001] The invention relates to the technical field of foundation construction of offshore construction platforms, in particular to a negative pressure sinking control system. Background technique [0002] The barrel foundation is a barrel-shaped structure with a closed top and an open bottom. It was first applied to offshore oil platforms and provided bearing capacity and seabed fixation for oil production platforms in shallow sea areas. In recent years, with the development of offshore wind power technology, barrels Barrel-shaped foundations are also used in the field of fan installation, therefore, the fixing technology of barrel-shaped foundations is also more and more concerned by those skilled in the art. [0003] In order to realize the sinking and pulling out of the barrel foundation, a set of sinking system is set up, which mainly includes valves, piping systems, vacuum pumps, centrifugal pumps, filters and control devices. [0004] During the sinki...

Problems solved by technology

[0005] However, due to the process of sinking and pulling up the barrel-shaped foundation, it is difficult to ensure that the pressures of the different chambers inside are the same, which will cause the pressure difference in the different chambers to be unbalanced, and then cause the rise or fall of the different chambers. The speed is inconsistent, which leads to the inclination of the barrel foundation. Under a certain inclination, the barrel foundation will increase the resistance of sinking and pulling up. In severe cases, the barrel foundation may not be able to sink to the set sinking position or The problem of not being able to pull out the barrel foundation from below

[0006] At present, the sinking control of the barrel foundation is mainly controlled manually or semi-automatically. The operator observes the inclination of the barrel foundation with the naked eye during the control of sinking or pulling up. shape foundation, push the barrel foundation to restore the level, or artificially change the working status of the valve or vacuum pump, centrifugal pump, and then adjust the barrel foundation recovery level; Construction Quality
