Abstract

The invention provides a component for reducing line lateral wind power of a straight pole under extreme strong wind, and relates to the technical field of electric power facilities. The component comprises a fixing hoop and U-shaped clamping pieces, wherein the fixing hoop is connected to the outer side of the straight pole, and dampers are connected to the two sides of the fixing hoop correspondingly; the number of the U-shaped clamping pieces is two, one U-shaped clamping piece is connected to the outer side of the fixing hoop, and the other U-shaped clamping piece is connected to the outer side of a wind shielding outer cover; and fastening bolts are connected inside the U-shaped clamping pieces, and the wind shielding outer cover is fixedly connected to the outer side of the straight pole through the U-shaped clamping pieces. According to the component, when the straight pole shakes under the influence of the line lateral wind power, the dampers on the two sides of the fixing hoop swing synchronously, the shaking amplitude of the straight pole is greatly reduced through self-swing of the dampers, the stability of the straight pole in extreme strong wind weather is guaranteed, the wind-resistant safety level of the straight pole is improved, and therefore, economic property loss caused by breakage of the bottom of the straight pole due to excessive shaking amplitude is avoided.

Description

technical field [0001] The invention belongs to the technical field of electric power facilities, and more specifically relates to a line lateral wind force component for reducing straight poles under extremely high winds. Background technique [0002] Telephone poles are poles for erecting wires. Telephone poles are generally used for lines with low voltage levels. Most of the telegraph poles are made of reinforced concrete. Telegraph poles are widely used in urban and rural power transmission projects. The rod is divided into two types: straight rod and tension rod. The straight rod is used in the straight part of the line and mainly bears the weight of the wire and the side wind force. [0003] Wind power components for straight poles can refer to Patent No. CN110894759A, which mainly includes electric poles, clamping sleeves, connecting cross bars and stable poles. The number of said electric poles is three, and each electric pole is evenly arranged from top to bottom T...
