Description
Technical Field
The invention belongs to the technical field of wind power generation, and particularly relates to a self-adjusting offshore wind power landing platform.
Background
For offshore wind power construction, the national thirteen-five planning proposes: the method mainly promotes the offshore wind power construction of Jiangsu, zhejiang, fujian, guangdong and other provinces, and the construction scale of the offshore wind power startup of the four provinces in 2020 reaches more than one million kilowatts; the offshore wind power construction of Tianjin, hebei, shanghai, hainan provinces (markets) and the like is actively promoted; the exploration is advanced on offshore wind power projects in Liaoning, shandong, guangxi provinces (regions) and the like. By 2020, the construction scale of offshore wind power on the whole country reaches 1000 kilowatts, and the accumulated grid-connected capacity reaches more than 500 kilowatts.
Unlike onshore wind power, offshore wind power is far from inland and, at present, mainly depends on ship transportation personnel or equipment to a fan platform in China. Compared with land, the landing difficulty of personnel or equipment is greatly increased by ocean complex and changeable stormy waves, geology and meteorological conditions. Under the current technical conditions, a certain risk exists in the process that the ship logs on the wind power platform: only when the wind waves are small, the ship board is controlled to be close to the fan ladder as much as possible, and a worker jumps to the ladder from the ship board and then climbs on the wind power platform; if a large storm is encountered, the landing behavior is dangerous because of the huge fluctuation of the hull and the huge static and dynamic difference formed by the static of the ladder stand of the wind turbine. The patent application number 201110151115.1 (offshore wind turbine platform landing device) prevents personnel from jumping and landing by inventing a gangway ladder and linking a shipboard with a fan ladder. Although reducing the risk of heave of the vessel, the device cannot be fixed to the fan platform, requiring that each vessel be equipped with the device, is very inconvenient to handle and increases the cost of the vessel landing on the fan.
The landing of the expensive helicopter platform and the landing of the semi-submersible platform are thrown away, and the floating platform with the box-type structure is connected with the fan, so that personnel do not need to climb the fan ladder stand, can directly land on the box-type floating platform through the ship board, the landing danger is well avoided, and the carrying of equipment is facilitated. However, the traditional box-type structure is fixed in height, is generally suitable for being used for a ship with a lower ship side to land, and is inconvenient to use. The patent application number of 20080228862. X (an offshore platform) adjusts the direct height difference between the buoyancy tank landing platform and the ship through the water injection/drainage holes of the buoyancy tank, and can adapt to the landing of a wider ship type. However, the water quantity adjustment is a displacement adjustment mode of the invention, so that the water quantity adjustment has a plurality of inconveniences. The adjustment of the amount of water in the buoyancy tank requires personnel to operate on the platform. Therefore, when the ship is on shore, if the initial height difference is large and no operator exists on the platform, the risk still exists that the operator logs in. Meanwhile, the water quantity adjustment is completed by an additional electric pump, and auxiliary facilities such as electric power and the like are needed, so that the water quantity adjustment is troublesome; and the water injection and drainage processes are slow. This patent has many problems in application.
In conclusion, the invention provides a safe offshore wind power landing platform capable of automatically adjusting the height difference with a ship board, which has good economic and social benefits.
