Description
Technical field
The utility model relates to offshore wind farm facilities, and in particular to more offshore wind power foundations built in one kind, it is applicable
In the offshore wind power development of deep water large capacity.
Background technique
In recent years, with global energy supply, energy security and ecological environment the problems such as, becomes increasingly conspicuous, and wind-powered electricity generation is as one
Kind renewable energy rapidly develops.China's wind energy on the sea lays in the 75% of the total wind energy of Zhan, and close to power load center.In recent years I
Using offshore wind farm as focus development field, offshore wind power development is grown rapidly for state.In order to reduce engineering development construction at
This, developing large capacity blower is inevitable trend.Meanwhile coastal waters shallow water area Wind Power Generation is gradually saturated, deep water wind-powered electricity generation is how
Exploitation is also the bottleneck for restricting the fast development of China's wind-powered electricity generation at present.Therefore reasonable base form is researched and developed to be suitable for deep water great Rong
Amount offshore wind power development is of great significance to offshore wind farm development.
Utility model content
The purpose of this utility model is to overcome deficiency in the prior art, solves foundation structure in the prior art and be directed to
The problems such as deep water large sized unit form is less, and the scope of application is small, and ground basis stability is difficult to ensure, is at high cost, provides one kind
Suitable for more built in deep water large capacity offshore wind power foundations.
The purpose of this utility model is achieved through the following technical solutions:
A kind of built-in more offshore wind power foundations, including cylinder top cover, the first subdivision plate, the second subdivision plate, sheath skirt plate and
Stub；The cylinder top cover and sheath skirt plate constitute a semiclosed cylinder type that Open Side Down, in semiclosed cylindrical structure
Middle part has been vertically arranged n block the first subdivision plate, and the first subdivision plate and cylinder top cover are formed with a positive n polygon cylinder that Open Side Down
Cavity；N block the second subdivision plate, the second subdivision are radially disposed on the rib of the cylinder cavity, in semiclosed cylinder type
Plate, cylinder top cover, sheath skirt plate are formed with the n identical and independent hemi-closure spaces that Open Side Down on the outside of cylinder cavity；N institute
It states stub to be evenly arranged on the second subdivision plate, the top of stub is connect with cylinder top cover, wherein n >=3.
Further, the height of the first subdivision plate and the second subdivision plate is lower than 0~3m of sheath skirt plate height.
Further, the length of the stub is greater than 0~5m of sheath skirt plate height；
Further, cylinder top cover, the first subdivision plate, the second subdivision plate, sheath skirt plate, stub are connected as one by welding manner
It is whole.
Compared with prior art, beneficial effect brought by the technical solution of the utility model is:
1. it is less that the utility model solves deep water large capacity base form, and increases to adapt to the poor ground in profundal zone
Construction cost the problems such as, upper load is passed in ground by the utility model wind power foundation in such a way that stake cylinder combines, together
When stake combined with bucket foundation and strong ensure that structural stability.
2. the utility model wind power foundation due to using mode of the stub in conjunction with cylinder base phase cleverly by top wind
The big load of machine is passed to ground, and the use of steel is greatly reduced under the premise of guaranteeing structure safety and stability.Simultaneously because knot
Structure is a kind of basis of wide shallow formula, can be using land fabrication-sea transportation by driving-negative pressure sinking single step installation, thus significantly
Difficulty of construction and construction cost are reduced, therefore there is good popularization and application foreground.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model wind power foundation.
Appended drawing reference: 1- top covers, 2- the first subdivision plate, 3- the second subdivision plate, 4- sheath skirt plate, 5- stub
Specific embodiment
The utility model will be further described with reference to the accompanying drawing.
As shown in Figure 1, more offshore wind power foundations built in one kind, by cylinder top cover 1, the first subdivision plate 2, the second subdivision plate
3, sheath skirt plate 4, stub 5 form；Cylinder top cover 1 and the semiclosed cylinder type that Open Side Down of the composition of sheath skirt plate 4 one；First subdivision
Plate 2 is arranged in inside semiclosed cylindrical structure, arranges n (n=6 in the present embodiment) block in the centre of semiclosed cylindrical structure
First subdivision plate 2 forms a positive n polygon cylinder cavity that Open Side Down with cylinder top cover 1；It is semiclosed on cylinder cavity rib
Radial arrangement the second subdivision of n block plate 3 of cylinder type, the second subdivision plate 3, cylinder top cover 1, sheath skirt plate 4 are in positive n polygon cylinder
The n downward hemi-closure spaces of identical separate openings are formed on the outside of cavity；N stub 5 is evenly arranged in radially arranged
On two subdivision plates 3, top and the cylinder top cover 1 of stub 5 link together；The height of first subdivision plate 2 and the second subdivision plate 3 is lower than
4 0~3m of height of sheath skirt plate；The length of stub 5 is greater than 4 0~5m of height of sheath skirt plate；Wherein cylinder top cover 1, the first subdivision plate 2, second
Subdivision plate 3, sheath skirt plate 4, stub 5 are integral by welding manner connection.
In the present embodiment, sheath skirt plate uses the steel plate of wall thickness 2cm, height 12m；Cylinder top cover steel plate thickness 1.5cm, diameter 38m；
First subdivision plate and the second subdivision plate thickness 1.5cm, height 12m；Stub thickness 1.5cm, diameter 4m, length 13m.
Above each component can prefabricated by land, assembling, final wind power foundation is navigated by maritime air float support, under negative pressure
It is heavy, until cylinder top cover and sea bed face are in close contact.
The utility model is not limited to embodiments described above.Above the description of specific embodiment is intended to describe
With illustrate the technical solution of the utility model, the above mentioned embodiment is only schematical, is not restrictive.?
