Power transmission tower capable of adjusting height

Abstract

The invention discloses a power transmission tower capable of adjusting the height. The power transmission tower comprises a tower body, a base, a transverse rod, a sliding groove and a lightning conductor. The base is fixedly connected to the lower end of the tower body, fixing piles are distributed at the lower surface of the base, a sliding groove is formed in the side wall of the tower body, the transverse rod runs through the sliding groove, a plurality of binding posts are fixedly connected to the upper surface of the transverse rod, the left and right ends of the lower surface of the transverse rod are each fixedly connected with a sleeve, a lead screw is arranged inside each sleeve, the lower end of each lead screw is sleeved with a driven bevel gear, a dual-shaft motor is fixedlyconnected to the middle of the tower body, the height of the binding posts can be conveniently regulated, and the topographical adaptability is greatly improved; meanwhile, binding and maintaining work can be performed conveniently, under the effect of wind force, a bell makes a noise to repel birds, birds are prevented from staying on the transverse rod, contaminations caused by bird dung on thedevice are avoided, short-circuits and other faults caused by bird activity are avoided, the fault occurrence rate is lowered, and when the tower is installed, the fixing piles are embedded underground, and the stability is improved.

Description

technical field

[0001] The invention relates to electric power equipment, in particular to a power transmission tower which is convenient for height adjustment. Background technique

[0002] The transmission tower is the supporting point of the overhead line. One circuit is erected on the transmission tower, which is a single-circuit transmission tower, and two circuits are erected on the transmission tower, which is a double-circuit transmission tower. According to its shape, it is generally divided into five types: wine glass type, cat head type, upper type, dry type and barrel type. According to the use, it is divided into: tension tower, straight line tower, corner tower, transposition tower, terminal tower and span towers, etc. However, the existing transmission towers are all fixed structures. When erecting wires, due to the inconsistent height of the ground surface, when the transmission towers are connected, the height difference between the terminals of each transmi...
