A device and method for monitoring the grouting sleeve of an offshore wind turbine and ensuring operation safety

Abstract

The invention discloses a device and method for monitoring the grouting sleeve of an offshore fan and ensuring operation safety, comprising a grouting sleeve; a slide rail assembly fixed on the grouting sleeve; a binocular camera, a binocular The camera is mounted on the slide rail assembly to check whether the underwater camera grouting sleeve is leaking; the cavity device with through holes is arranged at the lower end of the lower ring plate of the grouting sleeve. The outer diameter of the through hole is larger than the diameter of the pile casing, and its initial state is folded and compressed. After being filled with fillers, the cavity device with the through hole expands inwards and closely fits the outer wall of the pile casing; the terminal is used for When pre-grouting, receive the signal of whether the grouting sleeve is leaking from the binocular camera, and judge whether the grouting packer in the grouting sleeve is damaged. If so, trigger the cavity device with through holes to expand and fit the outer wall of the pile casing ; Receive the position information of the grouting sleeve through the feedback of the binocular camera during the operation period, and obtain the settlement amount of the sleeve through the binocular vision quantitative algorithm.

Description

technical field [0001] The invention belongs to the field of engineering monitoring, and relates to a device and a method for monitoring the grouting sleeve of an offshore fan and ensuring operation safety. Background technique [0002] Offshore wind energy, as a clean and stable renewable energy source, has seen an increase in global wind power generation year by year in the past decade. As the water depth of wind power development increases, more and more wind farms adopt the jacket foundation form. The grouting sleeve is used to connect the jacket and the pile foundation, which is one of the key components to ensure the safety of the support structure of offshore wind turbines. . [0003] At present, because the offshore wind turbine grouting sleeve is constructed underwater, the grouting packer is often damaged or partially detached, and pouring a large amount of grouting materials without knowing the situation at the time of grouting not only wastes a lot of money but ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the embodiments of the present invention is to provide a device and method for monitoring the grouting sleeve of an offshore wind turbine and ensuring operation safety, so as to solve the problem in the related art that the integrity of the grouting packer cannot be confirmed during the construction process, and the scope of grout leakage and Quantitative calculation of the amount of slurry leakage, unable to conduct safety monitoring of the long-term operation of the fan sleeve, and unable to guarantee a rapid early warning in case of a situation that endangers the safe operation of the structure
