Embodiment 1

[0030] Such as Figure 1 to Figure 2 As shown, this embodiment discloses a new type of windproof eccentric hammer, which includes a T-shaped heavy hammer body, the heavy hammer body is divided into a horizontal part and a vertical part 13, and the horizontal part is divided into the second part with the vertical part Half 11 and second half 12, wherein the horizontal length of the first half 11 is greater than the second half 12, so that the center of gravity of the weight sheet is set against the first half 11; the center of gravity of the weight sheet during installation Stay away from the side of the tower.

[0031] The hammer body is provided with a lower fixing hole 2 at the midline position of the vertical part, and an upper fixing hole 3 is arranged at a position corresponding to the lower fixing hole 2 on the horizontal part; wherein, the lower fixing hole 2 is a round hole, and the upper fixing hole 3 is The lower end fixing hole 2 is an arc-shaped long hole with the...

Embodiment 2

[0036] Such as image 3 As shown, this embodiment discloses a windproof eccentric weight hammer device, which includes the new windproof eccentric weight hammer 1 described in Embodiment 1, and also includes a connecting plate 7. The wires pass through the reserved holes around the connecting plate 7, and the connecting plate The two sides of 7 are symmetrically stacked with the new windproof eccentric hammer 1, and the lower connecting rod 8 passes through the lower fixing hole 2, and the upper connecting rod 9 and the lower connecting rod 8 pass through the upper fixing hole 3. And upper connecting rod 9 is kept on the connecting plate 7 by the novel windproof bias weight hammer plate 1 on both sides of the connecting plate 7.

[0037] The novel windproof eccentric hammer disclosed by the invention is different from the traditional heavy hammer, and adopts an eccentric design. The center of gravity is away from the side of the tower body, and a moment is applied to the wire...

Abstract

The invention discloses a novel anti-windage heavy hammer sheet, which comprises a T-shaped heavy hammer sheet body, wherein the heavy hammer sheet body is divided into a horizontal part and a vertical part, the horizontal part is divided into a first half part and a second half part by taking the vertical part as a boundary, the horizontal length of the first half part is greater than that of thesecond half part, the gravity center of the heavy hammer sheet body is close to the first half part, the gravity center of the heavy hammer sheet body is far away from a tower body side during installation, a lower end fixing hole is formed in the center line of the vertical part of the heavy hammer sheet body, an upper end fixing hole is formed in the horizontal part corresponding to the lower end fixing hole, the lower end fixing hole is a circular hole, the upper end fixing hole is an arc-shaped long hole with the lower end fixing hole as the circle center, the first half part or the second half part of the heavy hammer sheet body is provided with a heavy hammer sheet body stacking structure, and the heavy hammer sheet body stacking structure forms an energy consumption connecting mechanism. According to the invention, the novel anti-windage heavy hammer sheet can effectively prevent windage flashover, and can quickly absorb and consume wind energy acting on a wire through the energy consumption connecting mechanism between the heavy hammer sheet bodies.

Description

technical field [0001] The invention relates to the technical field of transmission line operation and maintenance, in particular to a novel windproof weighted hammer and a windproof weighted hammer device. Background technique [0002] Under the action of strong wind, the wire is excessively deflected to the side of the tower body. When the heavy rain reduces the air insulation and the lightning activity generates an induced voltage on the wire, it discharges the tower body, causing the line to trip, which is called wind deflection flashover. In recent years, due to the frequent occurrence of wind flashovers, it has remained high. In order to build a stronger power grid, it is imminent to study the wind deflection optimization of transmission line towers. [0003] The solutions adopted by the prior art are generally divided into three categories: [0004] 1. Install windproof insulating cables. This solution has the following disadvantages: the line fittings are suscepti...
