Problems solved by technology

[0007] However, there are some disadvantages in the traditional forward and inverted cone icebreaking structure, that is, when the height of the ice layer is at the junction of the forward and inverted cones, the moving ice row is blocked by the structure, which will cause greater crushing damage and reduce the impact of the cone. The ability of the body structure to reduce the ice load, and the current anti-ice cone does not have the ability to collect sea ice data and sea ice warning

Embodiment 1

[0047] An anti-ice cone for offshore structures such as figure 1 As shown, it includes a main body, an ice breaking device, an infrared smart high-speed ball 5 , a pressure sensing belt 6 , a monitoring module, a control device 11 and a computing module 12 .

[0048] The main body is two conical structures with equal bottom diameters. The bottom of the conical structures is a cone, and the top is a cylinder. Cone 2, the front cone 1 and the bottom surface of the inverted cone 2 are mated, and the cone angles of the vertebral bodies of the forward cone 1 and the inverted cone 2 are both 50°-65°.

[0049] The ice breaking device includes a horizontal blade 3 and a vertically rotating gear 4, and the horizontal blade 3 and the vertically rotating gear 4 are arranged at intervals outside the junction of the forward cone 1 and the inverted cone 2; as figure 2 As shown, the vertically rotating gear 4 is in the form of two gears biting each other, and the friction between the gears...

Embodiment 2

[0055] A kind of anti-icicle operation process for offshore structures, the specific steps are as follows:

[0056] (1) When it is found that the floating ice is close to the foundation of the offshore structure and the height of the ice layer is at the junction height of the forward and reverse cones, turn the horizontal blade and the vertically rotating gear to make the floating ice break from the middle and bend upward or downward, so as to achieve The purpose of reducing the ice load on the foundation.

[0057] (2) When the radar system detects the formation of floating ice within 1km, the infrared smart high-speed dome starts to work to monitor the sea surface in real time. When it recognizes a large area of ​​floating ice (generally ice floating with a horizontal scale greater than 20m) When starting to approach, the calculation module starts to work while automatically tracking the ice floe. The infrared smart high-speed ball records the actual moving distance L of the ...

Abstract

The invention discloses an ice-resistant cone for an offshore structure and an operation process of the ice-resistant cone. The ice-resistant cone comprises a main body of a forward and reverse cone structure, an ice breaking device, an infrared intelligent high-speed ball, a pressure sensing belt, a monitoring module, a control device and a calculation module. The monitoring module is provided with a radar system, a communication system, a storage battery and a solar panel. A method for separating an ice layer at the junction of the ice-resistant cone of the forward and reverse cone structureduring operation of the ice-resistant cone is simple and practical, the extrusion load borne by the junction of the forward and reverse cone of a traditional ice-resistant cone is converted into thebending load, and the cone structure and the offshore structure foundation can be protected more effectively; and compared with the traditional ice-resistant cone, the ice-resistant cone has the advantages that accurate data of sea ice disaster occurrence, development and change rules can be mastered, and sea ice disaster files are perfected.

Description

technical field [0001] The invention belongs to the technical field of marine engineering construction, and in particular relates to an anti-ice pick used for offshore structures and an operating process thereof. Background technique [0002] Sea ice is a marine disaster unique to polar and high-latitude sea areas. In my country, such disasters mainly exist in Liaodong Bay, Bohai Bay, Laizhou Bay and the northern part of the Yellow Sea. At the same time, due to the high density of wind energy reserves in the Bohai Sea and the northern part of the Yellow Sea, they are located in the Bohai Rim region. However, with the development of offshore engineering development activities such as offshore wind power and offshore oil exploration platforms, the application of single pile foundations is more extensive. When designing single pile foundations The effect of ice loading also needs to be considered additionally. [0003] Under the action of ice load, the overall movement of the ...
