Problems solved by technology

[0004] At present, most of the existing ice-breaking structures are fixed, and the ice force acting on the ice-breaking structure is directly transmitted to the jacket rod, which is easy to cause the jacket rod to be damaged by the repeated action of ice. It is urgent to study a set of retractable Ice-breaking structure to increase the service life of jacket rods

Embodiment Construction

[0037] A jacket ice-breaking structure with a vacuum cavity: such as Figure 7 As shown, it includes ice-breaking element 1, jacket rod 2, and steel pipe pile 8. The outer side of jacket rod 2 is covered with ice-breaking element 1. Ice-breaking element 1 and jacket rod 2 are connected by welding. Jacket rod 2 and The steel pipe piles 8 are connected by grouting or welding. The upper part of the steel pipe pile 8 structure is the jacket rod 2, and the lower part goes deep into the seabed. The whole structure is supported by the steel pipe pile 8 foundation and fixed at sea.

[0038] Such as Figure 8-12 As shown, the ice breaking element 1 includes a cone ring 3, a ball plate 4, a round rod 5, a spring 6, a vacuum valve 7 and a cylinder 9, and the cylinder 9, the ball plate 4 and the round rod 5 are all made of stainless steel alloy materials, and the outer Coated with epoxy resin type heavy-duty anti-corrosion coating. The cone ring 3, the spring 6, and the vacuum valve 7 a...

Abstract

The invention discloses an offshore jacket ice breaking structure with vacuum cavities. The offshore jacket ice breaking structure with the vacuum cavities comprises multiple high piles; offshore jacket rod parts are fixed at the top ends of the high piles; the outer walls, dipping in the water surface, of the offshore jacket rod parts are coated with cylinders; ball plates are mounted on the cylinders; the vacuum cavities for generating negative pressure on the sides of the offshore jacket rod parts are formed between the cylinders and the ball plates; multiple elastic elements are arranged on the outer walls of the ball plates; and ice breaking elements are annularly arranged and fixed at the outer ends of the telescopic elastic elements. The offshore jacket ice breaking structure with the vacuum cavities is simple in structure, excellent in ice breaking effect and capable of effectively prolonging the service life of an offshore jacket.

Description

technical field [0001] The invention relates to an ice-breaking structure of a jacket with a vacuum chamber, belonging to the field of ice-breaking structures. Background technique [0002] Ice, especially sea ice, is an important factor affecting the design and safe operation of marine structures in high-latitude seas. When sea ice interacts with marine structures, it is always designed so that the sea ice is destroyed first. The Bohai Sea and the northern Yellow Sea in my country are different every year. The degree of freezing, ice load is an important load in the structural design of Bohai ocean engineering. [0003] my country's Bohai Sea is rich in wind energy resources, and the offshore wind energy power generation market has broad development prospects. However, the Bohai Bay belongs to a high-latitude cold area, and there is sea ice on the sea every winter and spring, which has a great impact on the structure. To ensure the development of offshore wind energy resourc...
