Ballasting and load discharging system suitable for floating wind power platform and operation method

Abstract

The invention discloses a ballasting and load discharging system suitable for a floating wind power platform. The ballasting and load discharging system comprises a ballast tank, a first valve, a second valve, a water injection mechanism, an air pipe head and a pressurizing mechanism. The first valve is communicated with the lower part of the ballast tank; the second valve is communicated with thetop of the ballast tank through a pipeline; the water injection mechanism and the air pipe head are communicated with the second valve through pipelines; the pressurizing mechanism is communicated with the upper part of the ballast tank through a pipeline, and compressed air can be injected into the ballast tank through the pressurizing mechanism; the invention further discloses an operation method of the ballasting and load discharging system suitable for the floating type wind power platform, through opening and closing combination of the first valve, the second valve and the pressurizing mechanism, water can be fed into and discharged out of the ballast tank, and therefore low-frequency load adjustment of the floating type wind power platform is met. The ballasting and load dischargingscheme is simple in structure, simple in system configuration, low in investment cost, safe and feasible in operation, suitable for low-frequency load adjustment of the floating wind power platform and high in economic value.

Description

technical field [0001] The invention relates to the technical field of marine floating wind power platforms, in particular to a ballast and discharge system and an operation method suitable for floating wind power platforms. Background technique [0002] As the offshore wind resources and quality in the deep sea are better than those in the near sea, my country's offshore wind power is gradually developing in the direction of the deep sea. With the increase of water depth, the single pile foundation has been difficult to meet the requirements of offshore wind power technology due to technical and economic factors, and floating wind power platforms have become the mainstream direction. [0003] The main scale of the floating wind power platform is usually determined by demonstration and analysis from multiple overall directions such as stability performance and motion performance. The platform usually performs power generation operations under the specified draft, but the st...

Problems solved by technology

[0004] Aiming at the deficiencies in the existing technology, the present invention proposes a ballasting and unloading system and operation method suitable for floating wind power platforms to solve the high cost of the existing platform ballasting and unloading schemes proposed in the above-mentioned background technology , the structure is complex, so the low-frequency load adjustment will lead to the problem that the conventional high-cost platform ballast and discharge solutions are wasteful and inapplicable
