A kind of high-voltage transmission iron tower and its installation method

Abstract

The invention discloses a high-voltage transmission tower and an installation method thereof. Bird dispelling devices are installed above a cross arm of the high-voltage transmission tower, and each bird dispelling device comprises a base, a central bird avoiding pile and a plurality of bird trapping assemblies. Each bird trapping assembly comprises a vertical rod, a first spring and a cross rod, wherein the two ends of the first spring are connected with the vertical rod and the cross rod respectively, and the first spring is transversely arranged. Each central bird avoiding pile comprises a sharp-top rod, a second spring, a supporting rod and inclined struts, wherein the sharp-top rod, the second spring and the supporting rod are sequentially connected from top to bottom. Each base comprises a clamp, an outer cylinder and an inner column. The installation method of the high-voltage transmission tower includes the following steps of 1, erecting a tower body; 2, installing the bird dispelling devices, wherein the bird trapping assemblies and the base of each bird dispelling device are in a separated state before installation. The flat part of the tower is blocked, a flat mechanism is arranged, birds are made to regard the tower as a place not safe to inhabit based on the principle of attracting the birds and then scaring the birds, and thus the birds will not come again.

Description

technical field [0001] The invention relates to a high-voltage transmission iron tower and an installation method thereof. Background technique [0002] Because the power tower is tall and stable, it is a good place for birds to settle down. Birds especially like to perch on the flat cross arm of the tower, which will cause bird damage, and the insulators will flashover due to bird defecation. First, bird feces pollute the insulator strings. If there is too much feces accumulated, pollution flashover accidents will occur on the insulators; second, bird feces are a kind of mixed liquid with certain conductivity. When excreted from above, the bird droppings will fall along the edge of the insulator, forming a bird dropping channel with a certain conductivity near the edge of the insulator string. Phase-to-ground fault. [0003] Existing bird repelling devices mostly use sound or light emitting devices to scare birds. These devices only have a good effect when they are instal...

First, bird feces pollute the insulator strings. If there is too much feces accumulated, pollution flashover accidents will occur on the insulators; second, bird feces are a kind of mixed liquid with certain conductivity. When excreted from above, the bird droppings will fall along the edge of the insulator, forming a bird dropping channel with a certain conductivity near the edge of the insulator string. phase-to-ground fault

[0003] Existing bird repellent devices mostly use sound or light-emitting devices to scare birds. These devices have a good effect only after they are installed for a period of time. When the birds get used to the sound or light, the effect will become worse
