Sinking or floating control method and device of multi-chamber barrel-shaped base

Abstract

The invention relates to sinking or floating control method and device of a multi-chamber barrel-shaped base. The sinking or floating control method comprises the following steps of: setting a sinking preset depth or a floating preset height and a corresponding maximum preset inclined angle; detecting an actual depth or an actual height and a corresponding actual inclined angle; executing an automatic leveling step when the corresponding actual inclined angle is larger than the maximum preset angle, and stopping sinking or floating when the actual depth is equal to the preset depth, or the actual height is equal to the preset height. The control device comprises a detection unit and a control unit, wherein the detection unit comprises a first sensor and a second sensor; and the control unit receives a signal from the detection unit, compares the signal with a preset value and confirms whether the leveling operation is executed or stopped according to a comparison result. The sinking or floating control method and device ensure that the multi-chamber barrel-shaped base sinks and floats stably, save the time and the labor cost and have high movable and repeatable utilization ratio.

Description

technical field [0001] The invention relates to the technical field of equipment construction platform engineering in tidal flat areas, in particular to a control method for sinking and floating of a multi-chamber barrel foundation applied therein and a control device for controlling the sinking and floating. Background technique [0002] In recent years, with the development of wind power technology and the decrease of available wind resources on land, more and more wind power enterprises have shifted their development direction to the utilization of wind resources in shallow sea areas. Especially in tidal flat areas) the utilization of wind resources provides convenient conditions. However, due to natural phenomena such as high tide and low tide often appear in tidal flat areas, and the mud surface bearing capacity of tidal flats is low, this also brings great challenges to equipment construction in tidal flat areas. How to make the equipment construction platform in tidal...

AI Technical Summary

Problems solved by technology

[0005] 1. Due to the uneven softness and hardness of the soil at the bottom of the tidal flat, during the process of pumping or injecting water into each chamber, the multi-chamber barrel foundation often tilts to a certain extent. Since the multi-chamber barrel foundation is in the water For lower positioning, it is difficult to rely on manual detection, and it is easy to cause misjudgment, the accuracy of its level is low, and the control accuracy is poor; on the other hand, the method of sinking positioning and floating by manual detection depends on the operator The level of proficiency in the operation requires multiple (usually 3-4) operators to skillfully operate the lifting of the barrel-shaped foundation. The operation is complicated and labor-intensive, which increases labor and time costs;

[0006] 2. In the process of manual inspection, it is often necessary to adjust the level of the multi-chamber barrel foundation, and it is usually easy to be found when the barrel foundation has a large deflection, which will damage the underwater soft soil foundation and cause positioning errors. Instable, when the platform based on this kind of foundation is subjected to horizontal loads such as sea waves and wind, the platform may tilt, endangering the safety of equipment and operators on the platform, and even causing the platform to overturn. There is no safety and reliability. In addition, it is difficult to restore smooth operation after the soft soil foundation is damaged;

[0007] 3. Due to the difficulty of manual sinking, positioning and lifting of the multi-chamber barrel foundation, the mobility of the platform is poor, the installation cost is high, and it is difficult to reuse
