Description

Marine sealing device for offshore wind power steel pipe pile

Technical Field

The utility model relates to the technical field of deep-open sea ocean engineering, in particular to an offshore sealing device for an offshore wind power steel pipe pile.

Background

As offshore wind power gradually develops into deep sea, the jacket foundation gradually becomes a research hotspot in the current offshore wind power industry. The pile type jacket foundation is used as one of foundation forms in the field of offshore wind power engineering, the pile type jacket foundation and the steel pipe piles are connected through high-strength grouting materials and then are fixed on the sea floor, pile type jacket foundation construction is divided into a pile-first method and a pile-last method, if pile-first method construction is adopted, the steel pipe piles are driven to the designed elevation and then the jacket can be placed, after the steel pipe piles are driven, if the offshore construction conditions are poor, the jacket can be placed after waiting for the next window period, the time is two or three days, and the time is more than half a year. In this transition period, receive marine environment influence, the steel-pipe stake very big probability can produce the adjustment membrane to attracting bacterium, unicellular eukaryote and multicellular eukaryote in proper order at steel-pipe stake inner and outer wall adhesion, reproduction, until forming great fouling biological community, and the attachment of inner wall fouling biological community can produce adverse effect to the jacket and insert and connect the steel-pipe stake, consequently need clear up the steel-pipe stake inner wall specially before the jacket construction.

In addition, the steel pipe pile is inserted to the seabed, the distance from the top of the steel pipe pile to the sea surface is tens of meters, and if the steel pipe pile is stopped and anchored nearby when a common ship passes through the nearby sea, the steel pipe pile may be scratched, and damage to the steel pipe pile may be caused.

The prior marine attachment solving method can be divided into chemical inactivation, manual cleaning of the underwater of a diver and cleaning of an underwater robot, the chemical inactivation can have adverse effects on surrounding marine environments, the chemical inactivation is limited by the marine depth of the steel pipe pile, the manual cleaning difficulty is high, the risk is high, the time consumption is long, the diver has extremely high requirements, the cleaning effect is not ideal, the cleaning difficulty of the underwater robot is high, the cost is high, and the precision is difficult to control, so that the cleaning mode of the marine attachment of the traditional steel pipe pile is difficult to meet the application requirements of the current large-scale offshore wind power project.

In addition, the steel pipe pile is often located below the water surface by tens of meters, and is difficult to find by a common ship, so that when the ship breaks down in the process, the steel pipe pile is hung with probability, and damage is caused to the steel pipe pile.
