Problems solved by technology

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 and 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.
[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

Embodiment 1

[0031] Such as figure 1 , 2 , 3, the transmission iron tower for power transmission described in this embodiment includes a tower body 1, on which a number of cross arms 2 are arranged, and insulators 3 are provided at the ends of the cross arms 2; The top of the body 1 is provided with a water storage tank 4, and a water receiving tray 5 communicating with the water storage tank 4 is arranged above the water storage tank 4, and a filter layer 6 is provided on the upper surface of the water receiver tray 5, and the filter layer 6 can be a filter sponge. Or the upper layer is a filter sponge, and the lower floor is a stainless steel plate that is full of small holes to support the filter sponge. The function of the filter layer 6 is to clean the rainwater that is connected. The water in the interior evaporates too quickly; on each cross arm 2, a bird-repelling terminal 7 is also fixedly arranged; the bird-repelling terminal 7 includes a base plate 71, a control box 72, a pole ...

Embodiment 2

[0037] The power transmission tower used for power transmission described in this embodiment is different from embodiment 1 in that the value method of TB is different. Embodiment 1TB is a fixed value, and the water storage tank 4 has more water and less water and all adopts the same spraying time. , is not conducive to a more rational use of water sources; in fact, when the water storage tank 4 has less water, it is obvious that water should be saved to reduce the spraying time, so it is better to associate the TB with P. When P is greater than the value of PA, the water storage tank 4 The higher the liquid level, the larger the TB, and vice versa, the smaller the TB calculation formula to realize this idea is as follows:

[0038] TB=TBZ*(P-PA) / (PB-PA);

[0039] Wherein TBZ is a preset standard value, such as adopting 20 seconds, PB is equal to the water pressure value in the corresponding water tank 76 when the water level of the water storage tank 4 is full;

[0040] Using...

Embodiment 3

[0043] The power transmission tower used for power transmission described in this embodiment is different from Embodiment 1 in that the value method of TB is different, and the others are completely the same;

[0044] The TB value method is as follows:

[0045] Let I=(P-PA) / (PB-PA); P is the current water pressure; the preset value PA is equal to the water pressure value in the corresponding water tank 76 when the water level of the water storage tank 4 bottoms out; the preset value PB is equal to the water storage When the water level of the tank 4 is full, the corresponding water pressure value in the water tank 76; PA and PB are set in advance, P is measured on the spot, and I is calculated by the above formula;

[0046] When 1≥I>0.75; TB=0.5*TBZ

[0047] When 0.75≥I>0.5; TB= I* I*TBZ

[0048] When 0.5≥I>0.25; TB=0.5*I*TBZ

[0049] When 0.25≥I>0.125; TB= I*TBZ

[0050] When 0.125≥I>0; TB= 0.125*TBZ

[0051] TBZ is the preset standard value, 20-30 seconds is desirable ...

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...
