Abstract
Description
Technical Field
[0001] Embodiments of the present invention relate to the technical field of strain towers, and specifically, to a 66KV single-circuit strain tower. Background Art
[0002] For overhead power lines, there must be two types of towers, namely straight towers and strain towers. The tower located on the straight path is a straight tower, and the tower located at the turning position of the path is a strain tower. The strain tower is located at the turning point, and at this time, the forces on the tower cannot achieve balance between the front and back sides. According to the force analysis, it can be seen that it must bear the resultant force pointing towards the inner corner. The strain tower means withstanding tension.
[0003] Existing strain towers have a large number of steel structure supports. Especially, the top frame of the strain tower is relatively dense, and sometimes it will attract birds to build nests above the strain tower. Birds build nests on the transmission line towers. Since the bird nests are usually built at the positions where the top frame of the strain tower is relatively dense, that is, near the insulators, nest materials such as branches and iron wires reduce the insulation distance of most insulators. When encountering humid weather such as fog and rain, the nest materials such as branches with a certain degree of dirt become damp and the insulation drops significantly, resulting in relative ground or phase-to-phase short circuit faults, affecting the power transmission of the line. Moreover, the height of the bird nests is relatively high, and it is also inconvenient for manual cleaning. Summary of the Invention
[0004] To overcome the above defects, the present invention provides a 66KV single-circuit strain tower, which is used to solve the technical problems that bird nests in the prior art affect power transmission and are inconvenient to clean.
[0005] According to one aspect, at least one embodiment of the present invention provides a 66KV single-circuit strain tower, including a tower body and a cross arm. The cross arm is fixedly connected to the upper position of the tower body. It further includes a protective net, a wind-driven bird repelling mechanism, and a knocking mechanism. The protective net is fixedly connected to the outside of the upper position of the tower body. There are multiple protective nets, which are arranged around the upper position of the tower body. There are multiple wind-driven bird repelling mechanisms, which are arranged at the top of the tower body and at the positions on the tower body corresponding to the cross arm. The wind-driven bird repelling mechanism includes an installation box, a rotating shaft, and a wind receiving cover. The installation box is fixedly connected to the tower body through an installation frame. The rotating shaft is rotatably arranged on the installation box. There are multiple wind receiving covers, and multiple wind receiving covers are equally distributed at equal angles and fixedly connected to the outside of the rotating shaft. The knocking mechanism is used to knock on the protective net. The knocking mechanism includes a driving shaft, and the driving shaft is rotatably arranged on the tower body. Multiple elastic knocking rods are fixedly connected to the outside of the driving shaft.
[0006] To drive the drive shaft, a wind turbine is installed inside the installation box. The rotating shaft is fixedly connected to the input shaft of the wind turbine. A storage battery matching the wind turbine is installed inside the installation box, and the storage battery is used to supply power for the rotation of the drive shaft.
[0007] To improve the bird repelling effect, a plurality of reflectors are fixedly connected to the top end of the rotating shaft. The wind receiving cover drives the rotating shaft and the reflectors to rotate, and the reflected light generated by the reflectors repels the birds.
[0008] To further improve the bird repelling effect, anti-bird spikes are detachably connected to the outside of the protective net. The anti-bird spikes can reduce the standing space of the birds, thereby preventing the birds from staying on the tower body.
[0009] To further improve the bird repelling effect, a sensor for sensing birds is installed on the tower body, and the storage battery can supply power to the sensor.
[0010] To strike the cross arm and reduce the staying and nesting of birds on the cross arm, the mounting frame is in contact with the cross arm through a contact component. The contact component includes a locking screw and an adjusting seat. The locking screw is rotatably connected to the mounting frame, the adjusting seat is threadedly connected to the locking screw, the adjusting seat is fixedly connected with a contact rod, and the contact rod contacts the cross arm. Rotating the locking screw can drive the contact rod to contact the upper surface of the cross arm, which can improve the stability of the mounting frame and the wind-driven bird repelling mechanism. At the same time, the vibration generated by the wind-driven bird repelling mechanism and the knocking mechanism is transmitted to the cross arm, reducing the staying and nesting of birds on the cross arm.
[0011] To improve the stability of the contact rod, two baffles are slidably installed on the contact rod, and a damping pad is fixedly sleeved on the outside of the contact rod.
[0012] The beneficial effects of the embodiments of the present invention are as follows:
[0013] 1. In the present invention, the upper position of the tower body is protected by the protective net, that is, the position where the framework is relatively dense and birds are likely to nest, to prevent birds from drilling in, reduce the nesting space of birds, and at the same time reduce the approach of birds through anti-bird spikes, avoiding short circuits caused by bird nests at the insulator.
[0014] 2. In the present invention, the wind blows the wind receiving cover to rotate. The rotating wind receiving cover is in a moving state, repelling the birds at the tower body and the cross arm. At the same time, the wind receiving cover drives the rotating shaft and the reflectors to rotate, and the light reflected by the rotating reflectors will also repel the birds to a certain extent.
[0015] 3. In the present invention, the birds are sensed by the sensor, and the driving shaft is timely controlled to rotate, driving the elastic knocking rod to knock on the protective net, causing the protective net to vibrate and generate sound. At the same time, the vibration is transmitted to the cross arm through the mounting frame and the abutting rod, etc., to drive away the birds and prevent the birds from staying on the strain tower.
[0016] 4. In the present invention, when the wind blows the wind receiving cover to rotate, it drives the rotating shaft and the input shaft of the wind turbine to rotate. The wind turbine converts wind energy into electrical energy and stores it inside the storage battery, and the storage battery supplies power to the rotation of the sensor and the driving shaft, reducing energy consumption.
[0017] 5. Therefore, compared with the strain towers in the prior art, the present invention protects the top of the tower body through the protective net and the anti-bird spines, reducing the stay and penetration of birds. The wind blows the wind receiving cover to rotate to drive away the birds. At the same time, when the wind receiving cover rotates, the wind turbine generates electricity and stores the electrical energy inside the storage battery. When the sensor senses the approach of birds, it controls the driving shaft to drive the elastic knocking rod to rotate and knock on the protective net, causing the protective net and the cross arm to vibrate and emit sound, further realizing the precise driving away of birds and reducing the nesting of birds on the strain tower, thereby avoiding affecting power transmission.

[0032] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present invention, rather than limiting the present invention.
[0033] For the sake of simplicity of the drawings, only the parts related to the invention are schematically shown in each figure, and they do not represent the actual structure of the product. In addition, for the sake of simplicity and easy understanding of the drawings, in some figures, parts with the same structure or function are only schematically shown as one of them, or only one of them is marked. In this article, "one" not only means "only this one", but also can mean "more than one" situation, and "several" includes "two" and "more than two".
[0034] In this article, it should be noted that unless otherwise clearly defined and limited, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.
[0035] In the present invention, unless otherwise clearly specified and defined, the first feature being "on" or "under" the second feature may include the direct contact between the first and second features, or may include the situation where the first and second features are not in direct contact but in contact through additional features therebetween.

[0037] In addition, in the description of this application, the terms "first", "second", etc. are only used for differential description and cannot be construed as indicating or implying relative importance.
[0038] As Figures 1 to 8 shown, it shows a 66KV single-circuit tension tower in an embodiment of the present invention, including a tower body 1 and a cross arm 2. The cross arm 2 is fixedly connected to the upper position of the tower body 1. It further includes a protective net 3, a wind-driven bird repelling mechanism and a knocking mechanism. Compared with the tension towers in the prior art, in the present invention, the top of the tower body 1 is protected by the protective net 3 and the anti-bird spines 4 to reduce the stay and entry of birds. The wind blows the wind receiving cover 103 to rotate to drive away the birds. At the same time, when the wind receiving cover 103 rotates, the wind turbine 5 generates electricity and stores the electric energy inside the storage battery. When the sensor 6 senses the approach of birds, it controls the drive shaft 201 to drive the elastic knocking rod 203 to rotate, knock on the protective net 3, so that the protective net 3 and the cross arm 2 vibrate and make sounds, further realizing the precise repelling of birds, reducing the nesting of birds on the tension tower, and thus avoiding affecting power transmission.
[0039] As Figure 1 、 Figure 2 、 Figure 7 and Figure 8As shown in the figure, the protective net 3 is fixedly connected to the outside of the upper part of the tower body 1. There are multiple protective nets 3, which surround the upper part of the tower body 1. The aperture of the protective net 3 is small, which can prevent birds from drilling into the tower body 1. At the same time, the protective net 3 surrounds the tower body 1, especially the position of the top of the tower body 1 close to the insulator, making the surface of the tower body 1 smooth and preventing birds from building nests on the tower body 1. To further improve the bird repelling effect, a bird spike 4 is detachably connected to the outside of the protective net 3. The bird spike 4 can reduce the standing space of birds, thus preventing birds from staying on the tower body 1. The bird spike 4 can be tied to the outside of the protective net 3 or the cross arm 2 with iron wire. The bird spike 4 is composed of dense and scattered long-spike-shaped steel wires. Generally, steel wires with a diameter of 2 mm are used, and a middle spiral (spring-like) structure is adopted, which increases the elasticity, making it impossible for birds to stay and fly away. This not only ensures power safety but also avoids harm to birds.
[0040] As Figures 1 to 3 As shown in the figure, there are multiple wind-driven bird repelling mechanisms. The wind-driven bird repelling mechanisms are arranged at the top of the tower body 1 and the positions on the tower body 1 corresponding to the cross arm 2. The wind-driven bird repelling mechanism includes an installation box 101, a rotating shaft 102, and a wind receiving cover 103. The installation box 101 is fixedly connected to the tower body 1 through an installation frame 104. The installation frame 104 is installed on the steel structure of the tower body 1 by means of bolt connection or welding. The rotating shaft 102 is rotatably arranged on the installation box 101. There are multiple wind receiving covers 103, and multiple wind receiving covers 103 are evenly distributed and fixedly connected to the outside of the rotating shaft 102 at equal angles. A plurality of reflectors 105 are fixedly connected to the top of the rotating shaft 102. The wind receiving cover 103 drives the rotating shaft 102 and the reflectors 105 to rotate. The reflection generated by the reflectors 105 repels the birds. The wind-driven bird repelling mechanism is installed at a relatively high position on the tower body 1 where the wind force is large. When the wind blows, the wind receiving cover 103 starts to rotate. Birds are very vigilant and will not approach such dynamically changing objects, thus realizing the repelling of birds. At the same time, the wind receiving cover 103 drives the rotating shaft 102 and a plurality of reflectors 105 to rotate, and the reflectors 105 form a dazzling reflection effect, making the nearby birds feel uncomfortable and prompting the birds to stay away from the equipment area, thereby protecting the strain tower.
[0041] As Figures 1 to 4As shown in the figure, the knocking mechanism is used to knock on the protective net 3. The knocking mechanism includes a drive shaft 201, which is rotatably arranged on the tower body 1. A drive motor 202 is installed on the tower body 1, and the drive shaft 201 is fixedly connected to the output end of the drive motor 202. A plurality of elastic knocking rods 203 are fixedly connected to the outside of the drive shaft 201. By driving the drive motor 202, the drive shaft 201 can be driven to rotate, thereby driving the elastic knocking rods 203 to rotate. The distance between the drive shaft 201 and the protective net 3 is adjusted to be slightly less than the length of the elastic knocking rod 203, so that the elastic knocking rod 203 knocks on the protective net 3 during rotation. At the same time, the bending of the elastic knocking rod 203 reduces the resistance of the protective net 3 to the rotation of the elastic knocking rod 203. The protective net 3 vibrates and makes a sound when knocked. The vibration of the protective net 3 reduces the stay of birds and shakes off the branches of the bird's nest, damaging the construction of the bird's nest. At the same time, the sound scares and drives away the birds, further reducing the nesting of birds on the tower body 1.
[0042] As Figure 3 shown, in order to drive the drive shaft 201, a wind power generator 5 is installed inside the installation box 101. The rotating shaft 102 is fixedly connected to the input shaft of the wind power generator 5. A storage battery matching the wind power generator 5 is installed inside the installation box 101. The storage battery is used to supply power for the rotation of the drive shaft 201. When the wind blows and drives the wind receiving cover 103 and the rotating shaft 102 to rotate to drive away the birds, the rotating shaft 102 drives the input shaft of the wind power generator 5 to rotate. The wind power generator 5 converts the mechanical energy generated by the wind energy into electrical energy and stores it inside the storage battery. The storage battery supplies power to electrical components such as the drive motor 202 and the sensor 6, reducing energy consumption. A solar panel can also be installed on the top of the tower body 1 to assist in supplying power to the drive motor 202 and the like, further reducing energy consumption.
[0043] As Figure 1 、 Figure 2 and Figure 8 shown, in order to further improve the bird repelling effect, a sensor 6 for sensing birds is installed on the tower body 1. The storage battery can supply power to the sensor 6. The sensor 6 can be selected as a radar sensor 6 or an infrared sensor 6. When it senses the approach of birds or other organisms, the sensor 6 sends an electrical signal to the connected controller, controlling the drive motor 202 to start, driving the knocking rod to knock on the protective net 3, accurately driving away the birds, further reducing energy consumption, and at the same time reducing the damage to the elastic knocking rod 203 and the protective net 3.
[0044] As Figure 6As shown in the figure, in order to strike the cross arm 2 to reduce the stay and nesting of birds on the cross arm 2, the mounting frame 104 is abutted against the cross arm 2 through an abutting component. The abutting component includes a locking screw 301 and an adjusting seat 302. The locking screw 301 is rotatably connected to the mounting frame 104, the adjusting seat 302 is threadedly connected to the locking screw 301, the adjusting seat 302 is fixedly connected with an abutting rod 303, the abutting rod 303 contacts the cross arm 2, and rotating the locking screw 301 can drive the abutting rod 303 to contact the upper surface of the cross arm 2, which can improve the stability of the mounting frame 104 and the wind-driven bird repelling mechanism. At the same time, the vibration generated by the wind-driven bird repelling mechanism and the knocking mechanism is transmitted to the cross arm 2, reducing the stay and nesting of birds on the cross arm 2. Two baffles 304 are slidably mounted on the abutting rod 303, and a damping pad 305 is fixedly sleeved outside the abutting rod 303. Sliding the baffle 304 to make it close to the side surface of the cross arm 2 further improves the stability of the mounting frame 104. At the same time, when the locking screw 301 is tightened, the abutting rod 303 is limited, preventing the abutting rod 303 and the adjusting seat 302 from rotating with the locking screw 301. The damping pad 305 generates a large sliding damping between the baffle 304 and the abutting rod 303, ensuring the stability of the baffle 304. At the same time, the damping pad 305 improves the sliding damping between the abutting rod 303 and the cross arm 2, further improving the stability of the abutting rod 303.
[0045] The working principle or usage process of this 66KV single-circuit strain tower is as follows:
[0046] Install the protective net 3 and the mounting frame 104 at appropriate positions on the tower body 1, and install the anti-bird spines 4 at appropriate positions on the protective net 3 and the cross arm 2. The protective net 3 and the anti-bird spines 4 reduce the landing places of birds and prevent birds from drilling into the tower body 1;
[0047] The wind blows the wind-catching cover 103 and the rotating shaft 102 to rotate. The wind-catching cover 103 rotates to drive away birds, and the reflector 105 rotates with the rotating shaft 102 to drive away birds by light. At the same time, the rotating shaft 102 drives the wind turbine 5 to generate electricity to supply power to the drive motor 202 and the sensor 6. When the sensor 6 senses the approach of birds, it controls the drive motor 202 to start. The drive motor 202 drives the drive shaft 201 and the elastic knocking rod 203 to rotate. The elastic knocking rod 203 knocks on the protective net 3, driving the protective net 3 and the cross arm 2 to vibrate and make sounds, further driving away birds, reducing the stay and nesting of birds on the tower body 1, and reducing the impact on the power transmission of the strain tower.
[0048] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not restrictive. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
