Formula, corrosion fatigue is inevitable, becomes the security risk of operation wind turbine.The changeover portion on marine fan jacket steel structure basis is in
Splash zone, alternation of wetting and drying, it is difficult to be protected using modes such as sacrificial anode systems, anti-corrosion is difficult, and steel structure changeover portion node stress
High concentration, corrosion fatigue is especially serious, becomes structural weak link at changeover portion node.
Utility model content
The purpose of this utility model is to provide a kind of concrete changeover portions and the compound offshore wind turbine foundation of jacket, carry
High corrosion resistance, to increase service life, installation simple and convenient, solves the problems of the prior art.
To achieve the above object, the utility model provides following technical solution：A kind of concrete changeover portion is answered with jacket
Mould assembly offshore wind turbine foundation, including concrete structure cushion cap, three pile leader framves and negative pressure bucket, the concrete structure cushion cap it is upper
End is installed with pylon, and concrete structure cushion cap bottom is installed with concrete structure bottom plate, concrete structure bottom plate
Bottom is fixedly connected with the three pile leaders frame；Three pile leader framves are made of bearing tube and oblique pull pipe, and bearing tube is vertically arranged to
On three connectivity ports of concrete structure bottom plate, oblique pull pipe between bearing tube, the both ends of oblique pull pipe respectively with it is adjacent
Bearing tube is fixedly connected；The bottom of three pile leader framves is installed with the negative pressure bucket, and negative pressure bucket is embedded under sea bed face.
Preferably, the concrete structure cushion cap is located on sea level.
Preferably, the three pile leaders frame is a kind of component of steel construction.
Preferably, it is also equipped with air extractor on the negative pressure bucket.
Compared with prior art, the beneficial effects of the utility model are as follows：
This concrete changeover portion and the compound offshore wind turbine foundation of jacket, due to using concrete structure cushion cap with mixing
The integral transition segment structure of Xtah Crude Clay structure bottom plate, the shortcomings that eliminating traditional steel structure changeover portion node stress high concentration, effectively
The corrosion fatigue that avoids cause damage problem, improve the fatigue life of structure, make runtime anticorrosion maintenance workload big
It is big to reduce.
Description of the drawings
Fig. 1 is the overall structure figure of the utility model；
Fig. 2 is the vertical view of the utility model.
In figure：1 concrete structure cushion cap, 2 pylons, 3 concrete structure bottom plates, 4 three pile leader framves, 5 bearing tubes, 6 oblique pulls
Pipe, 7 negative pressure buckets, 8 air extractors.
Specific embodiment
The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out
It clearly and completely describes, it is clear that the described embodiments are only a part of the embodiments of the utility model rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are without making creative work
All other embodiments obtained shall fall within the protection scope of the present invention.
Please refer to Fig.1-2, a kind of concrete changeover portion and the compound offshore wind turbine foundation of jacket, including concrete structure
Cushion cap 1, three pile leader framves 4 and negative pressure bucket 7, concrete structure cushion cap 1 are located on sea level, concrete structure cushion cap 1 it is upper
End is installed with pylon 2, and 1 bottom of concrete structure cushion cap is installed with concrete structure bottom plate 3, concrete structure bottom plate
3 bottom is fixedly connected with three pile leader framves 4；Three pile leader framves 4 are made of bearing tube 5 and oblique pull pipe 6, and bearing tube 5 is pacified vertically
On three connectivity ports loaded on concrete structure bottom plate 3, oblique pull pipe 6 is between bearing tube 5, the both ends difference of oblique pull pipe 6
It is fixedly connected with adjacent bearing tube 5, since three pile leader framves 4 are a kind of component of steel construction, so as to sound construction, not easily broken
It splits；The bottom of three pile leader framves 4 is installed with negative pressure bucket 7, and negative pressure bucket 7 is embedded under sea bed face；It is also equipped on negative pressure bucket 7
Air extractor 8 can be extracted out the gas in negative pressure bucket 7 by air extractor 8, so as to change the pressure of negative pressure bucket 7.
This concrete changeover portion and the compound offshore wind turbine foundation of jacket, due to using concrete structure cushion cap 1 with
The integral transition segment structure of concrete structure bottom plate 3, has the shortcomings that eliminating traditional steel structure changeover portion node stress high concentration
The corrosion fatigue that avoids of effect causes damage problem, improves the fatigue life of structure, makes runtime anticorrosion maintenance workload
Greatly reduce.
In summary：This concrete changeover portion and the compound offshore wind turbine foundation of jacket, improve corrosion resistance,
Increase service life, and install it is simple and convenient, compared with traditional steel structure jacket offshore wind turbine foundation, the present apparatus, coagulation
Native changeover portion corrosion fatigue resistant ability is remarkably reinforced, and runtime anticorrosion maintenance workload greatly reduces, so as to push away extensively
Wide application.
While there has been shown and described that the embodiment of the utility model, for the ordinary skill in the art,
It is appreciated that can these embodiments be carried out with a variety of variations in the case of the principle and spirit for not departing from the utility model, repaiied
Change, replace and modification, the scope of the utility model are defined by the appended claims and the equivalents thereof.
