For solving above-mentioned technical problem, the utility model provides a kind of tower barrel of wind generating set, including Hypomere tower and connected epimere tower, with described epimere outside the upper end of described hypomere tower Fit tightly inside the bottom of tower, and the place of fitting tightly of described hypomere tower and epimere tower sets There is securing member.
As a kind of improvement of the present utility model, described securing member includes pre-stressed bolt and coordinates with it Nut, and be arranged at pad between described screw bolt and nut.
Improving further, the upper end of described hypomere tower is provided with multiple equally distributed U-type groove, institute The bottom stating epimere tower is provided with the bolt mounting holes that multiple and described U-type groove is corresponding.
Improve further, corresponding three bolt mounting holes of described each U-type groove.
Improve further, inside the bottom of described epimere tower, be provided with positioning retainer ring.
Improving further, described hypomere tower and epimere tower are up-small and down-big circular cone bench-type structure.
Improve further, between described screw bolt and nut, be additionally provided with spring washer.
Using above-mentioned technical scheme, the utility model at least has the advantage that
The utility model utilizes the thinking of the epimere tower nesting hypomere tower of segmented tower, and employing has The friction-type being beneficial to rack load connects tower technology, and is bolted, effectively solve by In Flange joint, tower is born unit moment of flexure and is passed to the fatigue load of bolt, and fatigue load is held It is easily caused bolt failure, causes a difficult problem for major accident.
The utility model is internally provided with location ring washer in epimere tower, it is ensured that the location that tower is installed.
Accompanying drawing explanation
Above-mentioned is only the general introduction of technical solutions of the utility model, in order to it is new to better understand this practicality The technological means of type, makees the most in detail the utility model with detailed description of the invention below in conjunction with accompanying drawing Describe in detail bright.

Fig. 2 is the partial schematic diagram of hypomere tower upper end in the utility model tower barrel of wind generating set;
Fig. 3 is the partial schematic diagram of epimere tower bottom in the utility model tower barrel of wind generating set;
Fig. 4 is the connection partial cutaway schematic of epimere tower and hypomere tower in the utility model.
Detailed description of the invention
Generating set tower in the present embodiment uses the circumferential segmented tower that Wind turbines is traditional, Wherein as a example by three sections of tower, but being not limited only to 3 sections, the utility model is only for illustrating this segmented Interconnection technique between tower and mode, wouldn't limit other special installation etc. inside tower.
Referring to the drawings shown in 1, the present embodiment tower barrel of wind generating set, including hypomere tower 2 and with Its connect epimere tower 1, outside the upper end of this hypomere tower 2 with in the bottom of epimere tower 1 Side fits tightly, in friction-type nested encryptions, and the fitting tightly of hypomere tower 2 and epimere tower 1 Place is provided with the securing member for connecting hypomere tower 2 and epimere tower 1.
In the present embodiment, hypomere tower 2 and epimere tower 1 are up-small and down-big circular cone bench-type structure, It can certainly be up-small and down-big frustum type structure.
Wherein securing member is pre-stressed bolt 3 and the nut coordinated with it, and is arranged at bolt 3 He Pad 4 between nut.Acting as of this pad 4: one is the pad effect playing nut, and two are to ensure that Bolt can stress uniformly.
For the ease of installing, referring to the drawings shown in 2 to 4, the upper end of hypomere tower 2 is provided with multiple Equally distributed U-type groove 21.The bottom of epimere tower 1 is provided with multiple corresponding with U-type groove 21 Bolt mounting holes 11.Then after epimere tower 1 with hypomere tower 2 friction-type nested encryptions, can pass through This bolt mounting holes 11 and the cooperation of U-type groove 21, install fastening bolt 3.And U-type groove is set herein The purpose of 21 is: when installing epimere tower 1, first installs bolt in each of which bolt mounting holes 11 3, so when epimere tower 1 being sling and to hypomere tower 2 nesting, this bolt 3 plays to epimere The purpose of tower 1 location, it is ensured that epimere tower 1 falls according to certain position, until hypomere tower 2 Upper end outside fit tightly inside the bottom of epimere tower 1.So this U-type groove 21 was both kept away Exempted to carry out between two sections of tower the radial error of bolt installation, facilitate again the installation of epimere tower 1 with just Position.
In order to increase the connective stability of upper-lower section tower further, corresponding three spiral shells of each U-type groove 21 Bolt installing hole 11.
The present embodiment is also provided with positioning retainer ring 12 inside the bottom of epimere tower 1, it is simple to upper-lower section Location when tower is installed, and this positioning retainer ring 12 may also operate as increasing tower circumferencial direction rigidity Effect.
In the present embodiment, hypomere tower 2 can also spray special painting with the place of fitting tightly of epimere tower 1 Layer, to increase the frictional force between hypomere tower 2 and epimere tower 1.And above-mentioned bolt 3 He Spring washer or other packing ring it is also provided with between nut.
The installation method of the utility model tower barrel of wind generating set is as follows: when hypomere tower 2 is just installed After Wei, preparing to install epimere tower 1, now epimere tower 1 is all pacified in each bolt mounting holes 11 Dress bolt 3, nut now is simply mounted on bolt guarantee and does not falls off;Then epimere is carried out The lifting of tower 1, now bolt 3 is as the positioner of epimere tower 1, it is ensured that epimere tower 1 Fall according to certain position at circumferencial direction, until the end face of hypomere tower 2 and epimere tower 1 Positioning retainer ring 12 is fitted completely;Then the nut of all bolts 3 is removed one by one, at each bolt 3 Upper installation pad 4, the most again nut of prestressed bolt 3;Finally refer to according to tower installation exercise Lead the work such as the book fastening carrying out bolt 3.
In the utility model, the friction-type between tower barrel of wind generating set segmentation connects, and two sections of tower walls lead to Cross several pre-stressed bolt to carry out prestressing force and compress the frictional force produced between steel plate and pass to resist unit The moment of flexure of tower, effectively improves asking of bolt frequent failure fracture under current tradition tower connected mode Topic, can effectively improve the life-span of wind power generating set.
The utility model can improve security performance and the maintenance cost of Wind turbines in wind power generation field, Effective technical scheme is provided for the new technology of wind power generating set and cost declining, lifting reliability.
The above, be only preferred embodiment of the present utility model, not makees the utility model Any pro forma restriction, those skilled in the art utilize the technology contents of the disclosure above to make a little letter Single amendment, equivalent variations or modification, all fall within protection domain of the present utility model.
