Device for reducing ice load of ocean engineering structure by utilizing hydrothermal solution spraying unit

Abstract

The invention discloses a device for reducing ice load of an ocean engineering structure by utilizing a hydrothermal solution spraying unit. The device comprises a hydrothermal solution spraying unit, a lifting mechanism, a supporting end and a liquid storage container, wherein the liquid storage container is connected with the hydrothermal solution spraying unit through a heating and pressurizing device and a circular pipeline; the hydrothermal solution spraying unit is fixed on the lifting mechanism through connecting pieces; one end of the supporting end is connected with the lifting mechanism while the other end of the supporting end is fixed on the ocean engineering structure through an anchoring base; the joint between the anchoring base and the ocean engineering structure is higher than the sea level; and the hydrothermal solution spraying unit is provided with a spraying nozzle. The device for reducing ice load of the ocean engineering structure by utilizing the hydrothermal solution spraying unit, disclosed by the invention, has the advantages of being capable of melting down sea ice frozen on a water-ward surface of the structure efficiently, enabling the sea ice to separate from the structure, reducing or removing the ice load and decreasing damage of the sea ice to the structure.

Description

technical field [0001] The invention relates to a hydrothermal spraying device, in particular to a device for reducing the ice load of marine engineering structures by using a hydrothermal spraying unit. Background technique [0002] In cold regions, the damage of ice load to marine engineering structures is extremely serious. In March 1969, the Bohai No. 2 platform in my country, the torch platform in the Bohai No. 4 platform group in 1977, and the two oil platforms in Cook Inlet, Alaska, USA, collapsed under the action of ice loads in 1964. On January 28, 2000, the JZ20-2 Zhongnan platform vibrated violently, resulting in fatigue fracture of the exhaust pipeline of Well No. 8 and natural gas leakage. With the further development and utilization of my country's offshore oil and gas resources and marine renewable energy, how to reduce the damage of ice loads to marine structures is becoming more and more important. [0003] At present, many domestic experts and scholars ha...

Problems solved by technology

[0003] At present, many domestic experts and scholars have conducted in-depth and detailed research on the structural characteristics, strength characteristics, dynamic characteristics of ice itself, ice-induced vibration, and ice temperature expansion force. The model test method, the similarity law of the dynamic ice force model, and the reduction measures of ice loads need to be further studied, and there is no device for reducing the ice loads of marine engineering structures.
