A method for automatic discharge of gas inside the monopile foundation of offshore wind turbines

Abstract

The invention discloses a method for automatically discharging gas inside a single-pile foundation of an offshore wind power unit. The method mainly uses a rubber hose + a one-way valve for automatic exhaust, wherein one end of the rubber hose extends into the single-pile foundation, and the other One end passes through the tower door and extends out of the tower to connect to the one-way valve. The one-way valve is based on the set gas pressure value. When the gas pressure inside the monopile foundation reaches the gas pressure value, it will automatically open the valve to discharge the gas inside the monopile foundation. Gas, reducing the internal pressure of the single pile foundation, so as to control the gas pressure in the single pile foundation to meet the standard requirements. After the gas is discharged, the gas pressure inside the single pile foundation is reduced and the concentration of harmful gases is reduced. The one-way valve is closed, and the gas pressure outside the single pile foundation Neither gas nor liquid can reversely flow into the monopile foundation, so as to ensure the safety of operators and the safe and reliable operation of offshore wind turbine equipment.

Description

technical field [0001] The invention relates to the technical field of offshore wind turbines, in particular to a method for automatically discharging gas inside a monopile foundation of an offshore wind turbine. Background technique [0002] It is known in the industry that offshore wind power generation is developing rapidly, and the foundation types used by offshore wind turbines are also different, such as jacket foundation, monopile foundation, floating foundation and so on. For the monopile foundation, due to its cylindrical structure, it is in a relatively closed space after installation, but the sea mud, seawater, marine organisms that cannot be discharged during installation will accumulate inside the foundation, and a certain amount of gas will be generated , such as carbon dioxide, and even toxic hydrogen sulfide, methane, carbon monoxide and so on. If more and more gas is generated and not treated effectively, it will cause immeasurable danger, which will not on...

Problems solved by technology

If more and more gas is produced without effective treatment, it will cause immeasurable dangers, which will not only affect the safety factor of the working environment of the operators, but also may cause adverse effects on the unit

[0003] At present, for the gas produced by the biodeposition of the single pile foundation of offshore wind turbines, either the gas is allowed to increase without treatment, or the smart sensor is used for real-time monitoring. When the gas concentration reaches the alarm value, the blower is started to blow the gas out of the foundation. The former It will cause great safety hazards to operators and equipment. The cost of the latter is high, and a set of equipment is about 30,000 to 40,000 yuan, which is not conducive to the large-scale promotion and implementation of wind farms.
