Description
Technical field
It is that one kind bucket foundation wind turbine suitable for deepwater environment is whole the present invention relates to offshore wind farm construction method
The control method of sinking posture.
Background technology
In recent years, China's offshore wind farm development impetus is swift and violent, has built up multiple marine wind electric fields in succession.Offshore wind farm
, turbulivity bottom good with wind field condition is not take up the advantages such as arable land, at present to build in offshore, offshore waters more.But, with
The construction of the increase of eastern region power demand and the adjustment of domestic electrical structure, China's offshore wind farm certainly will be gradually to deep-sea
Direction is developed, this also just proposes wind power foundation structure new requirement certainly.
Compound cylinder-shaped foundation structure gradually applies to as a kind of novel foundation structure in the construction project of offshore wind farm,
It has advantages, the application prospects such as design is simple, bearing capacity is high, single step installation very good.And with China's sea turn
Electric construction sets the raising that the region depth of water requires, and the deep water construction condition of cylinder-shaped foundation structure is also gradually increased, and is embodied in basis
On the method for sinking of structure.Currently, the construction of wind-powered electricity generation is more to be in neritic area, since the marine site depth of water is shallower, under bucket foundation
It is heavy mainly to be acted on by wave factor, it floats up and down.Therefore, engineering circles mostly use hawser and control bucket foundation with hoist engine
Catenary motion, be finally completed sinking.For abyssal environment, since seawater is deeper, wave only influences surface layer waters, deep layer waters
Receive being affected for stream.Different from wave, ocean current (trend) can generate structure the continuous action power of a direction.For cylinder
The larger structure of the area of passages such as type basis is sunk in ocean current (trend), if only vertical control is without other directions
Control be likely to cause the structures slope in sinking watching, can topple when serious.For the wind-powered electricity generation knot of single step installation
Structure, the control accuracy higher sunk, or even 0.5% inclination angle cannot occur, it otherwise can seriously affect the operation peace of wind turbine
Quan Xing.
For this reason, it is necessary to propose a kind of construction method sunk for deep water, this method both can control the water that basis sinks
Pingdu also can control its vertical height, construction and the operational safety of structure be effectively ensured.
Invention content
The application is directed to a kind of bucket foundation sinking attitude control method suitable for deepwater environment, ensures deep water ring
The dirty effect in border does not make structure generate greater obliquity, to improve construction and the operational safety performance of bucket foundation.
In order to achieve the above object, the technical solution adopted by the present invention is：
Bucket foundation wind turbine entirety deep water sinking attitude control method, including basic head cover, upper part connect changeover portion, mistake
It crosses section to connect with tower, atop a tower fixed generator, generator connects blade, further includes realizing wind turbine entirety deep water sinking appearance
The vertical master control system and horizontal direction master control system of state control.
Further, the vertical master control system is by vertical suspension centre, vertical hawser, the vertical common structure of control hoist engine
At vertical suspension centre is set to above basic head cover, and circumferential homogeneous radiation shape is arranged at changeover portion outer rim；Each vertical suspension centre is logical
It crosses vertical hawser and connects vertical control hoist engine.The vertical suspension centre quantity is 4~8.
Further, the horizontal direction master control system controls hoist engine by horizontal direction suspension centre, oblique pull hawser, horizontal direction
It collectively forms, horizontal direction suspension centre is set on tower, and circumferential homogeneous radiation shape is arranged in tower；Each horizontal direction suspension centre is logical
Cross oblique pull hawser connection horizontal direction control hoist engine.The horizontal direction suspension centre quantity is 4~8, at horizontal direction hoisting point position
At the 3/4~4/5 of tower height.
Further, the changeover portion is connect by flange with tower.
Further, the total pulling force of oblique pull hawser is the 1/ of the construction secure power sunk for realizing bucket foundation wind turbine
4~1/2.
Further, including anticollison block, it is arranged between the foundation side wall and workboat inner wall of bucket foundation wind turbine.
The beneficial effects of the invention are as follows：Bucket foundation wind turbine entirety deep water sinking attitude control method using vertical suspension centre,
Vertical hawser, vertical control hoist engine mode realize vertical control, using horizontal direction suspension centre, oblique pull hawser, horizontal direction control
The mode of hoist engine processed realizes the control of horizontal direction.The control in above-mentioned two direction can independently be carried out, and development can be also cooperateed with,
Existing division of labor difference greatly enhances bucket foundation wind turbine overall structure in deepwater environment sinking watching there is also interrelated
In controllability, improve sinking safety and stability, ensure that the requirement for horizontality of integral installation.In addition, used in this method
Equipment is all conventional equipment, and installation process is simple, and controllability is strong, low-cost, is had good with foreground.
