Description

Technical Field

[0001] The invention belongs to the technical field of automatic construction of negative pressure bucket foundations, and in particular relates to a docking system for a suction pump group of an offshore wind power bucket foundation. Background Art

[0002] In the construction of offshore wind turbine foundations, suction pump groups are used as automated construction systems for the sinking and recovery of negative pressure barrel foundations. At present, the domestic pump group system used for suction barrel foundation construction and the barrel foundation docking process mainly use a hydraulic claw mechanism to lock the two parts. This docking method is difficult to effectively guarantee the connection strength and sealing effect. Furthermore, the hydraulic clamping mechanism is complicated to dock. In the event of control failure, it is difficult to manually separate the connection with the suction barrel, which will cause great safety hazards and economic losses to personnel in deep-sea diving operations. Based on this background, it is necessary to design a docking system for offshore wind turbine barrel foundation suction pump groups. Summary of the invention
