Abstract
With the theme of "Research on design and Maintenance of frost and thaw protection for hydropower stations in high cold area", this paper discusses the key technologies and strategies of design and maintenance of frost and thaw protection for hydropower stations in high cold area in view of the extreme low temperature environment. The harsh climatic conditions, especially the long period of low temperature, freezing and freeze-thaw cycle, pose a severe challenge to the safe and stable operation of hydropower stations. This paper aims to provide scientific basis and technical support for improving the freeze-thaw capability and operational stability of hydropower stations in high cold areas by systematically analyzing the necessity, design principles and specific measures of freeze-thaw protection design of hydropower stations in high cold areas, as well as the importance, maintenance content and methods of freeze-thaw protection. This paper emphasizes the importance of frost and thaw protection design for hydropower stations in high cold area. In low temperature environment, the key facilities such as channels, pipelines and gates of hydropower stations are prone to freezing, frost heaving and frost cracking, which seriously affects the normal operation and economic benefits of hydropower stations. Therefore, scientific and reasonable design of anti-freezing and thawing is the premise to ensure the safe and stable operation of hydropower stations in the high cold area. In this paper, the basic principles of anti-freezing and thawing design are elaborated, including thermal insulation, heat insulation, structural optimization, etc., and a variety of anti-freezing and thawing design technologies are introduced, such as channel covering insulation material, pipeline heating and insulation, gate antifreezing device, etc. In this paper, the key contents and methods of anti-freezing and thawing maintenance of hydropower stations in high cold area are discussed. Antifreeze and thawing maintenance is an important link to ensure the long-term stable operation of hydropower station, including daily inspection, regular maintenance, troubleshooting and emergency treatment. This paper puts forward a variety of anti-freezing and thawing maintenance measures, such as strengthening the drainage of channels to reduce the accumulation of frozen water, checking and repairing the damaged thermal insulation layer regularly, and cleaning the ice on the gate in time. At the same time, this paper also emphasizes the matters that should be paid attention to during maintenance, such as avoiding maintenance operations at extreme low temperatures and ensuring the safety of maintenance personnel. This paper summarizes the research results of frost and thaw protection design and maintenance of hydropower stations in high cold area, and puts forward the future research direction. With the progress of science and technology and the innovation of materials, the design and maintenance technology of anti-freezing and thawing of hydropower stations in high cold areas will be continuously optimized and improved. Future research should focus on the development and application of new thermal insulation materials, efficient heating equipment and intelligent anti-freezing and thawing monitoring system, so as to further improve the anti-freezing and thawing capability and operational stability of hydropower stations in high-cold areas.
