Description
Invention field
The system that wind obtains electric energy production is the present invention relates to the use of, and more particularly, to the whirlpool by wind-force effect driving
Turbine support tower, the tower are manufactured into by structural material according to building building technology, are preferably manufactured into by concrete.
The prior art
Electric energy production using wind is the turbine by wind-force effect driving based on use, and the turbine set, which is mounted in, is pacified
In cabin (pod) on tower top, turbine is highly prone to higher.More high tower is important, this is because the speed of wind
Increase with the increase away from the distance on ground, and wind turbine produce power with wind speed cube and change thing
It is real.Therefore, the tower used at present has a height of 100 meters or higher, and can be by with metal structure or mixed structure
Concrete structure is made, and upper section is metal structure in mixed structure.
The limiting factor of the height of tower is the fact that, i.e. known technology is based on using very big and has high load
The crane of ability, its height are higher than the height for the tower built.Therefore, the crane cause increase tower (mainly by
Made of concrete those) height be not economically feasible.
Overcoming the known technology of the above problem, to include the use of by tower section (tower section) (be general cylindrical
And there is gradually smaller diameter) made of retractable structure, the tower section is by means of setting in section itself
Standby continuously to be lifted, the equipment is such as tension force jack (tensile jack), hydraulic jack, pinion rack group
With similar miscellaneous equipment.In view of in the construction for being subject to wind-force to act on, active force in its structure with highly increasing rapidly,
The diameter of tower section reduces towards top, from about 3 meters of about 10 meters at base portion at top.
Patent document WO2013/083852 and WO2013/083853 are the representatives of the prior art, and first describes and can stretch
The known technology of the tower assembly of contracting.Fig. 1 (Fig. 3 based on open WO2013/083852) of the application describes cylindrical tower area
Section group, including the section 2 with small diameter of upper position is will be lifted to, and with the concentric of the diameter to diminish successively
Section 4,6 and 8, they occupy the centre position in assembling tower, and column foot portion is section 10, and section 10 can have cylindrical shape
Shape, or as shown in the figure, the low portion including conical butt.
According in the entitled " U.S. Patent Application No. 2012/ of Telescopic Tower Assembly and Method "
Known technology described in No. 0159875, by the way that the cylinder being assembled concentrically on common base section is linked together
The tower section is made.Interior zone with minimum diameter, which is first, to be assembled, and assembling has continuously successively
The other section of the diameter to become larger, and the group is similar to the appearance shown in the Fig. 1 being already mentioned above, wherein tower section 2,4,6
And 8 still on the common base 15 associated with exterior tower section 10.Although the figure shows the institute in higher position
Base portion is stated, but the tower section can be supported on the concrete base being molded in ground.
Fig. 2 depicts the overall appearance of representative tower section, in the case of being referred to as 4 tower section in Fig. 1, wherein noting
Anticipate and arrive, cylinder-shaped body is provided with thickened section in its lower end, so as to form prominent ring 4a.Upper end is provided with to form recessed ring
Other thickened section 4b.Therefore, and as shown in figure 3, tower section 2 is provided with lower prominent ring 2a and the inside ring at upper end
2b；Tower section 4 is provided with one prominent ring 4a and the inside ring 4b in a top, such, but except exterior tower section
Outside 10, exterior tower section 10 only has inside upper ring 10b.
Tower assembling includes being attached to cable 17-2,17-4,17-6 and 17- of tower section 2,4,6 and 8 by means of lower end
8 continuance lifting tower sections.The cable jack for example, by being supported on the upper surface of inside ring 4b, 6b etc. respectively
14-2,14-4 etc. are tensioned.Although attached drawing illustrate only two cables and two jack, however, it is understood that can use multiple
Cable and corresponding jack, the cable and jack are regularly distributed in the whole periphery of the ring.
Fig. 3 is related to the beginning of operation, and wherein tower section 2 is in intermediate altitude, passes through the cable being tensioned by jack 14-2
17-2 is hung.At the end of the initial step, the upper surface of inside ring 2a is contacted with the lower surface of prominent ring 4b, such as Fig. 4
It is shown specifically.Therefore, this joint portion by bolt 16 come integrated, to ensure that the monomer-type of tower section 2 and 4 shows.
Fig. 5 shows the stage more posteriorly of tower assembling process, wherein, joint portion is between section 2 and section 4, Yi Ji
Integrated between section 4 and section 6, jack 14-2 and 14-4 are removed.According to this figure and corresponding details, jack 14-6
Just in tensioned cables 17, the lower end of the cable is attached to the lower surface of the ring 6a of section 6, and section 6 is lifted together with section 2 and 4
Rise.
In this case, group 2-4-6 is hung by cable 17, therefore, the vertical degree of tower and correspondingly its stabilization
Property is closely related with the correct simultaneously operating of jack 14-6.In fact, and according to the detail view shown in this figure, ring 6a
There is no rigid connection, such connection between ring 8b to be only only possible when the ring contacts.Due to group 2-4-6's
In lifting process, the fact that such ring is separated by the gap around cable 17, the unstable balance of described group of presentation is this flat
Weighing apparatus may be subject to the further infringement of the lateral wind pressure marked by the horizontal arrow in Fig. 5.
In addition, field practice is it has been shown that (here it is the feelings of above-mentioned example in the tower of the stacking including a large amount of sections
Condition), in view of several operations must be performed by assembling team, assembly operation needs the relatively long time.
Patent document WO 2013/083853 is related to joint portion between tower section (for example, that illustrated in detail in Fig. 4
Details a bit).Fig. 6 a (it has reproduced Fig. 2 of document WO 2013/083853) show the details of the joint component, i.e. hold
The lower tower section wall (1) of weight and corresponding inside ring (3), the wall (2) of supported tower section and corresponding prominent ring
(4), bolt (6), the bolt make joint integrally, there is provided the mutual compression stress between the contact surface (5) of the ring.
The main element in the joint portion that Fig. 6 b are illustrated in figure before showing, and act on main in the joint portion
Power, i.e. by the vertical force Vp of the thin-walled transmission of upper tower section, its tower section corresponded to above joint portion (is originally showing
In example, section 2) weight, and the vertical force Vr corresponding to reacting force of supporting, vertical force Vr are by the thin of load-bearing tower section 4
Wall transmission.Since tower section has the fact that different diameters, the power is not conllinear, causes a pair of of momentum (a binary of
Momentum), its approximation is M=Vp × d, associated with horizontal component H.
The momentum M cannot be by structure compensation, because the thin-walled of section 2 and 4 can only carry vertical active force.Therefore,
Horizontal component H works, to produce rupture in the wall of one or two tower section, such as shown in Fig. 6 c.
It may also be noted that in running tower is assembled and in, by wind to tower structure and power generation turbine
Those power that pressure produces, weight Vp can increase, and which increase one or more joint portions in tower to occur catastrophic break
Risk.
Goal of the invention
In view of the above situation, the object of the present invention is to provide it is a kind of can be with compared with the time needed for the tower of the prior art
Substantially reduce the tower of Assembling time.
Another purpose is to provide a kind of assemble method, it eliminates possible unstable in the lifting process of tower section
Or it is uneven, to reduce the risk that drops in assembling process.
Another purpose is to provide a kind of device to avoid the joint portion recurring structure collapse between the tower section of stacking
Risk.
