Description

Technical Field

[0001] The utility model relates to the technical field of offshore wind power pile positioning frame monitoring, in particular to an offshore wind power pile positioning frame monitoring system. Background Art

[0002] In recent years, the development of new energy industry has become increasingly strong, and the construction of offshore wind power is in full swing. The offshore wind power piling technology has gradually matured and has various forms, including single pile, four piles, pile groups and other foundation forms. Regardless of the foundation form, in order to obtain high-precision pile foundation position and orientation, a pile positioning frame is required to assist in piling. By obtaining accurate positioning frame position, orientation, attitude and other data, the accurate pile foundation position is obtained. When installing the positioning frame, accurate monitoring data needs to be provided for real-time reference by the command center, and the positioning frame is adjusted in real time by the crane until the piling requirements are met.

[0003] When the piling technology was not yet mature, the monitoring of the wind power piling positioning frame often required personnel to board the positioning frame. When the crane ship hoisted the positioning frame, the surveyors conducted real-time measurements on it and reported the monitoring data to the command center through walkie-talkies and other communication methods. When the positioning frame was hoisted during offshore construction, it was in a shaking state. The surveyors also had to measure its position, posture and other data on the positioning frame. The data measurement was inaccurate and there were huge safety hazards. In addition, the measurement data was real-time, and there would be a certain time difference when broadcasting through walkie-talkies, which had an adverse effect on the command and affected the construction efficiency.
