Detailed Description
The first embodiment is as follows: as shown in fig. 1 to 3, the present embodiment describes an electric tower vortex-induced vibration suppression device, which includes a first steel wire rope 1, a basket 2, a second steel wire rope 3, a spoiler 4, and two third steel wire ropes 5; two ends of the flower basket 2 are respectively provided with a first hanging ring; one end of the first steel wire rope 1 penetrates through a first hanging ring at one end of the flower basket 2, and then is bundled and fixed by a plurality of first steel wire rope clamps; one end of the steel wire rope II 3 penetrates through the hanging ring I at the other end of the flower basket 2 and then is bundled and fixed by a plurality of steel wire rope chucks II; the other end of the steel wire rope II 3 penetrates through a lifting ring II 6 arranged at one end of the spoiler 4 and is bundled and fixed by a plurality of steel wire rope chucks III; one end of each of the two steel wire rope III 5 penetrates through the two lifting rings III 10 arranged at the other end of the spoiler 4, and then the steel wire rope III is bundled and fixed by a plurality of steel wire rope chucks IV.
The second embodiment is as follows: as shown in fig. 1 to fig. 3, the spoiler 4 of the present embodiment is further described as an embodiment one, and comprises a second hanging ring 6, a first locknut 8, a panel 9, two third hanging rings 10, two second locknuts 12, and three connecting lugs; the three connecting lugs are a first connecting lug 7 and two second connecting lugs 11 respectively; 9 one end middle part welding of panel has a engaging lug 7, and 9 other end symmetrical welding of panel has two engaging lugs 11 (being engaging lug 7 promptly and two 11 of two engaging lugs are isosceles triangle settings), rings two 6 and 7 threaded connection of engaging lug are fixed (prevent that connecting thread is not hard up) through lock nut 8 locking, every three 10 of rings are fixed with two 11 threaded connection of an engaging lug that correspond and are locked through lock nut two 12 (prevent that connecting thread is not hard up).
The third concrete implementation mode: as shown in fig. 1, in this embodiment, the number of the first plurality of wire rope clamps, the second plurality of wire rope clamps, and the third plurality of wire rope clamps is at least three (the binding can be made stronger), which is described further with respect to the first or second embodiment.
Example (b):
the utility model discloses a when the device used, connect wire rope 1 other end on the cross arm of electricity tower body of the tower, connect two three 5 other ends of wire rope on the crossbeam of being connected with section tower diaphragm to this device is installed equally to the offside. When wind blows along the direction of the tower body, the spoiler 4 swings, the force transmitted to the tower body by the first steel wire rope 1 and the second steel wire rope three 5 changes, and therefore the structure of the tower body cannot be damaged.
The working principle is as follows: the other ends of the first steel wire rope 1 and the third steel wire ropes 5 are respectively connected with the tower body of the power transmission and transformation tower, and the flower basket 2 (which is an existing standard component) is screwed tightly. Because the three connecting lugs (the first connecting lug 7 and the second connecting lug 11) of the spoiler 4 are in an isosceles triangle unstable structure mode, the spoiler 4 can rotate under the action of wind, at the moment, the first steel wire rope 1 and the third steel wire rope 5 are further pulled, the pulling force is transmitted to the tower body structure, the natural frequency of the tower body is changed, and the pulling force transmitted to the tower body is also changed at any time because the swinging angle and the vibration frequency of the spoiler 4 are changed along with the wind force and the pulsation frequency, so that the wind vibration frequency cannot be consistent with the natural frequency of the tower body, and the tower body and the wind generate resonance.
The above embodiments are merely illustrative of the present patent and do not limit the scope of the patent, and those skilled in the art can make modifications to the parts thereof without departing from the spirit and scope of the patent.
