A transmission tower for power transmission

Abstract

The invention discloses a power transmission iron tower used for power transmission. The power transmission iron tower comprises a tower body, wherein the tower body is provided with a plurality of cross arms; insulators are arranged at the end parts of the cross arms; a water storage tank is arranged at the top of the tower body; a water receiving disc communicated with the water storage tank is arranged above the water storage tank; a bird dispelling terminal is further fixedly arranged on each cross arm; when an infrared detection sensor detects that birds exist nearby, a controller controls a sound making device to carry out sound bird dispelling; when the birds are not successfully expelled by sounds, the controller opens a water outlet valve if water pressure in a water tank meets requirements, and water is sprayed out by utilizing self pressure of the water to dispel the birds; and if the water pressure in the water tank does not meet the requirements, the controller still starts the sound making device to carry out the sound bird dispelling. Compared with the prior art, the power transmission iron tower has the advantages that the bird dispelling effect is obviously improved, and the insulators are not easily damaged by pecking; the wandering time of the birds on the power transmission iron tower can be effectively shortened and excretion frequency is effectively reduced; and the birds are not easily nested on a power line, so that the safety of the power transmission is ensured.

Description

technical field [0001] The invention relates to electric power equipment, in particular to a power transmission tower for power transmission. Background technique [0002] The transmission tower is an important equipment in the power transmission system. The transmission tower is exposed to the wild and often suffers from various bird damage, which seriously affects the safety of the power grid. There are three main situations where birds harm power transmission and transformation equipment: 1. Pecking at insulators. 2. Building a nest on the power line is easy to cause an instantaneous short circuit. 3. Excretion on power transmission and transformation equipment, resulting in a decrease in insulation performance, or even insulation failure. In order to effectively prevent bird damage, it is necessary to use scientific and feasible means to drive birds away from the vicinity of power transmission and transformation facilities, but at the same time, from the perspective of...

In order to effectively prevent bird damage, it is necessary to use scientific and feasible means to drive birds away from the vicinity of power transmission and transformation facilities.

[0003] Existing bird repellents are usually windmill type bird repellent and double ball type bird repellent. The windmill type bird repellent relies on natural wind to make the windmill rotate, so that the bird is frightened, so as to achieve the bird repellent effect; its existing problems are: There is no bird-repelling effect on a windless day. Secondly, it is easy to be adapted by birds, and the bird-repelling effect is poor; the double-ball bird repellent includes double-ball outer ball bird repellent and inner ball light repellent bird repellent. The equipment is used to drive birds away in such a way that birds cannot land and are afraid. This method also has problems, that is, it is easy to be adapted by birds, and the effect of driving birds is poor;

[0004] Chinese patent transmission tower L201410221948X for power transmission discloses a relatively advanced intelligent bird repellent device, which can automatically detect the approach of birds through infrared sensors, and send out ultrasonic signals through ultrasonic circuits, and use ultrasonic waves to effectively drive birds away. The whole device is not affected by weather factors such as light, and can work around the clock. The whole device has a simple structure, is easy to install and use, and has strong practicability. However, the problem with it is that through a single ultrasonic bird repelling mode, the birds have adapted over time. The effect of repelling birds will also become worse
