Description

Technical Field

[0001] The utility model relates to the technical field of double-circuit pole towers, in particular to a double-circuit pole tower device in a medium ice zone. Background Art

[0002] With the explosive growth of new energy projects, more and more projects are covered with ice in the medium ice zone. In previous projects, heavy ice zone towers were usually used as substitutes. Since heavy ice zone towers are all single-circuit towers, the economic indicators of overhead transmission line projects in the medium ice zone are too large, and the transmission line channels are tight. At the same time, in recent years, transmission line accident statistics show that transmission towers are prone to collapse after being subjected to external forces such as earthquakes and strong winds, causing large-scale power outages and personal casualties, which is extremely dangerous.

[0003] Under the influence of earthquakes and typhoons, the cross-diagonal members of the tower body first undergo significant deformation, and the main members lose the effective restraint of the cross-diagonal members, causing the main members of the tower body to become unstable and damaged; the tower body is subjected to uneven force, which further leads to line failures, reduced power supply reliability, and reduced power operation stability. At the same time, the number of line tripping accidents caused by birds is not only gradually increasing, but also showing an upward trend, which has a great impact on the safe operation of the power grid. The maintenance cost of transmission towers in the medium ice area is higher. For this reason, we propose a double-circuit tower device for the medium ice area. Utility Model Content

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] Example 1: Figure 1 - Figure 5 As shown in the figure, a double-circuit pole tower device in a medium ice area includes a tower body 1, a lower base 7 and an upper base 701, and also includes: a ground wire cross arm 3, the ground wire cross arm 3 is symmetrically fixedly connected to the top of the tower body 1, the ground wire cross arm 3 is used to hang the ground wire, and double ground wire hanging points are set on both sides of the ground wire cross arm 3 to provide good lightning protection for the conductor. A top plate 4 is fixedly provided on the top of the ground wire cross arm 3, and a tower leg 2 is fixedly connected to the bottom of the tower body 1, and the tower leg 2 is fixedly connected to the top surface of the upper base 701, and an expulsion mechanism 5 is provided to expel the ground wire. The expelling mechanism 1 5 is symmetrically fixedly installed on the top of the top plate 4, and the expelling mechanism 1 5 is used to expel birds; and the expelling mechanism 2 6, which is located between the two expelling mechanisms 5, and is fixedly connected to the top plate 4, and is used to cooperate with the expelling mechanism 1 5; and the shock-absorbing mechanism 8 fixed between the lower base 7 and the upper base 701, the shock-absorbing mechanism 8 is used to protect the tower body 1; and the protective component 9 fixed on the outside of the lower base 7, the protective component 9 is used to protect the shock-absorbing mechanism 8.

[0022] For further information, see Figure 2 The expelling mechanism 1 5 includes a vertical rod 501, and the two vertical rods 501 are fixedly installed on the top of the top plate 4. The sides of the two vertical rods 501 away from each other are rotatably connected to the rotating shaft 502, and the sides of the two rotating shafts 502 away from each other are fixedly connected to blades 503. The outsides of the multiple blades 503 are fixedly connected to protective shells 504, and the insides of the multiple protective shells 504 are fixedly provided with mirrors 505. The principle of expelling birds here is: under the action of wind, the rotating shaft 502 drives the blades 503 to rotate. At the same time, the mirrors 505 rotate with the blades 503, reflecting the sunlight through the mirrors 505, and using the birds' fear of light to expel birds, while not harming the birds, so that people and nature can live in harmony.

[0023] For further information, please refer to Figure 3 The expelling mechanism 2 6 includes a protective box 601, which can protect its internal structure and increase the service life of the expelling mechanism 2 6. The protective box 601 is fixedly installed on the top of the top plate 4. An ultrasonic bird repeller 602 is fixedly installed inside the protective box 601. The ultrasonic bird repeller 602 adopts a physical bird repeller method and uses ultrasonic waves to drive birds away from the transmission tower, thereby reducing the impact of birds on the safety of the power grid. An inverter 606 is fixedly installed on one side of the ultrasonic bird repeller 602, and a lithium battery 603 is fixedly installed on one side of the inverter 606. Propagation holes 605 are evenly arranged on the side wall of the protective box 601. The propagation holes 605 are used to cooperate with the ultrasonic bird repeller 602. The sound is propagated through the propagation holes 605 to reduce the approach of birds. At the same time, the expelling mechanism 1 5 and the expelling mechanism 2 6 do not require personnel supervision, which can reduce costs and have high practicality.

[0024] Example 2: Figure 5 As shown, this is a further description of the first embodiment. In this embodiment, the shock absorbing mechanism 8 includes a fixed plate 801, and multiple fixed plates 801 are respectively fixedly installed on the side where the lower base 7 and the upper base 701 are close to each other. The tops of the multiple fixed plates 801 are fixedly connected to the connecting plates 802. Shock absorbing dampers 803 are provided between the multiple connecting plates 802. The shock absorbing dampers 803 are viscous dampers. The two ends of the multiple shock absorbing dampers 803 are movably connected to the two connecting plates 802 respectively. When an earthquake occurs, under the action of the shock absorbing dampers 803, when the damping medium passes through the throttling structure, the throttling resistance friction heat is generated to generate energy consumption, thereby reducing vibration, protecting the transmission tower, and thus improving the safety of the transmission tower.

[0025] The protective component 9 includes protective cotton 901. The protective cotton 901 is elastic inside and has a warming effect, which can protect the shock absorber 803 at low temperatures. At the same time, the protective component 9 can also increase the stability of the protective cotton 901 on the upper base 7 and the lower base 701. Multiple protective cottons 901 can be detachably set on the outside of the lower base 7 and the upper base 701. The outsides of multiple lower bases 7 are fixedly connected to long plates 902. The tops of multiple long plates 902 are fixedly connected to side plates 903. The insides of multiple side plates 903 are rotatably connected to two-way screws 904. The two-way screws 904 are double-threaded. The ends of multiple two-way screws 904 away from the side plates 903 are fixedly connected to a turntable 908. The outsides of multiple two-way screws 904 are symmetrically rotatably connected to sliders 90 5. The exteriors of the multiple sliders 905 are all fixedly connected with protective plates 906. The bottoms of the multiple sliders 905 are all fixedly connected with limiting rods 907. The limiting rods 907 support and limit the sliders 905. The multiple limiting rods 907 are all slidably connected with the long plate 902. By rotating the turntable 908, the two sliders 905 are driven to approach each other, and then the two protective plates 906 are driven to approach each other. The shock-absorbing damper 803 is protected from the outside by the protective cotton 901. At the same time, the protective component 9 can be quickly disassembled so that the staff can perform maintenance and inspection on the shock-absorbing mechanism 8, thereby improving maintenance efficiency.

[0026] In summary, when using this device, when birds approach the tower body 1, under the action of wind, the shaft 502 drives the blades 503 to rotate, and at the same time, the mirror 505 rotates with the blades 503, reflecting the sunlight to drive away the birds. When there is no wind, the ultrasonic bird repeller 602 emits sound, which is transmitted through the propagation hole 605, thereby driving away the birds. The solar panel 604 absorbs solar energy and converts it into usable power through the inverter 606 and stores it in the lithium battery 603, providing power for the ultrasonic bird repeller 602. The power source is that when an earthquake occurs, under the action of the shock-absorbing damper 803, when the damping medium passes through the throttling structure, throttling resistance friction and heat are generated to generate energy consumption, thereby reducing vibration and protecting the transmission tower. At the same time, by rotating the turntable 908, the two sliders 905 are driven to move closer to each other, and then the two protective plates 906 are driven to move closer to each other, and the shock-absorbing damper 803 is protected from the outside by the protective cotton 901, thereby increasing the service life of the shock-absorbing damper 803 and thus improving the safety of the transmission tower.
