4, the anti-dancing device of highly energy-consuming provided by the invention, the spring of employing can have the energy of absorption and reset function.
5, the anti-dancing device of highly energy-consuming provided by the invention, simple in structure, easily manufactured, economic performance is good, and suitable large-scale promotion is used.
6, the anti-dancing device of highly energy-consuming provided by the invention, be easy to install, and can realize supporting with sub-lead spacer.
7, the anti-dancing device of highly energy-consuming provided by the invention, the anti-dance performance is good, has effectively suppressed the transmission line galloping under ice wind exciting.
The accompanying drawing explanation
Fig. 1 is: highly energy-consuming anti-dance apparatus structure schematic diagram provided by the invention;
Wherein: 1, lid; 2, rubber-based highly energy-consuming material; 3, base; 4, yoke plate; 5, spring.
Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in further detail.
It is example that the present embodiment be take the anti-dancing device of highly energy-consuming, and as shown in Figure 1, the anti-dancing device of the highly energy-consuming that the embodiment of the present invention provides comprises: cover 1, rubber-based highly energy-consuming material 2, base 3, yoke plate 4, spring 5; Lid 1 and base 3 are welded, yoke plate 4 be arranged on cover 1 and the cavity of base 3 in; Lid 1 closely is connected with the conductor spacer on wire by bolt, guarantees that this device can move up and down along with waving of wire; The base 3 reserved apertures of central authorities, from then on the plate handle of yoke plate 4 passes in hole, and by the hung bolt weight; Rubber-based highly energy-consuming material 2 be arranged on cover 1 and the cavity of yoke plate 4 in, and adopt vulcanization process to process, to guarantee the adhesion strength of rubber-based highly energy-consuming material 2 and lid 1 and yoke plate 4; Be provided with spring 5 between the boss of yoke plate 4 and base 3, spring 5 provides certain rigidity, can meet the requirement of initial displacement under static load, also can guarantee that yoke plate 4, after each the movement, can return to initial position; Obvious for guaranteeing energy consumption effect, reduce the shearing rigidity of this device, the bonding edge thickness of rubber-based highly energy-consuming material 2 and lid 1 and yoke plate 4 is greater than the thickness in the middle of it, forms rubber-based highly energy-consuming material 2 top and bottom and all caves at middle position, edge is thick, the structure of intermediate thin.
This device is arranged on the conductor spacer of transmission line wire, under ice, wind effect, when the wire vibration-generating, this device will move thereupon, and yoke plate 4 produces relative slippage with rubber-based highly energy-consuming material 2, reaches the effect of power consumption; In addition, this installs in the conductor galloping process, produces the inertia force with the guidewire movement opposite direction, displacement and the acceleration of wire is also had to certain control action, i.e. tuned mass damper, TMD (TMD) effect.
Finally should be noted that: above embodiment is only in order to illustrate that technical scheme of the present invention is not intended to limit, although with reference to above-described embodiment, the present invention is had been described in detail, those of ordinary skill in the field are to be understood that: still can modify or be equal to replacement the specific embodiment of the present invention, and do not break away from any modification of spirit and scope of the invention or be equal to replacement, it all should be encompassed in the middle of claim scope of the present invention.
