Description
Technical field
The present invention relates to Oversea wind power generation field, in particular, relate to one and be applicable to
The novel offshore wind farm buoyant foundation at deep-sea.
Background technology
Along with the day by day exhaustion of traditional fossil energy, wind energy is sent out in recent years as a kind of clean energy resource
Rapidly, wherein Offshore Wind Power Generation Technology is because its wind speed is stable, wind shear is little, distance load in exhibition
The advantages such as center is near have and have great development prospect.But wind-power electricity generation equipment in offshore sea waters is logical
The pile foundation or the gravity type foundation that are often used are the most sensitive to marine site change in depth, in the depth of water relatively
Big marine site is difficult to meet safe and stable, economic and environmental requirement.
Summary of the invention
The invention aims to overcome deficiency of the prior art, it is provided that one aims to
A kind of wind-power electricity generation buoyant foundation solving the problems referred to above and design, the present invention can solve effectively
The certainly stable problem of wind-power electricity generation buoyant foundation, the depth of water bigger marine site, the letter of this buoyant foundation structure
Single, reasonable in design reliably bearing capacity is strong, adaptable to marine site topographic and geologic condition,
There is the strongest practicality.
It is an object of the invention to be achieved through the following technical solutions: a kind of wind-power electricity generation floating base
Plinth, including with entering the tower of manhole, tower upper end connects blower fan, the lower end of described tower
Being connected by ring flange and floating drum are fixing, described floating drum is bowl-shape frustum cone structure, described floating drum
Periphery be provided with support beam, floating drum be internally provided with bone interconnective with described support beam
Setting a roof beam in place, being provided with bottom floating drum is ring, and described system ring passes through hawser and the suction anchor going deep into seabed
It is connected, described floating drum is additionally provided with the staircase structure entering manhole described in extending to.
Described staircase structure includes the stair being arranged within floating drum and is arranged on above floating drum
Side hanging ladder.
Described floating drum is for sealing structure.
The domatic structure that described floating drum top is set to middle height, surrounding is low.
Described hawser is tension tendon.
The triangular structure consolidated it is interconnected between described framework beam.
Compared with prior art, technical scheme is had the benefit that
1. it is that ring is cleated and the suction going deep into seabed by steel bottom the buoyant foundation of the present invention
Anchor is firm to be connected, even if also can guarantee that Oversea wind power generation in the depth of water compared with area big, that waters is wide
Machine is properly functioning and reliable and stable.
2. the present invention can install and use in the marine site that the depth of water is bigger, beneficially environmental conservation, with
Time it also avoid the seabed silt adverse effect to base fixed；And steel cleat length can be with sea
End hypsography makes respective change, also can apply under the conditions of the topographic and geologic of seabed change.
3. the integrated model of the present invention has certain pliability, it is allowed to produce certain displacement deformation,
Space in buoyant foundation is fully utilized simultaneously, both can power transmission system as blower fan
Layout place, refuge can be stopped as Jobs on the sea personnel again, for National Sea provide
Source exploitation provides convenient；
The present invention designs simply the most generally, and degree of safety is high, structure respectively to carrying the uniform same sex,
Ocean environmental loads complicated and changeable there is is good adaptability, there is good safety with suitable
The property used.
