Description

Technical Field

[0001] The invention relates to the technical field of bird repellers, in particular to a bird repeller for power transmission lines. Background Art

[0002] Overhead transmission lines are mostly erected in open areas with few trees and in the wild mountains. Since overhead transmission lines not only cover a wide area but are also erected at a high height, birds usually use overhead transmission lines as a place to stay when foraging or migrating. In other words, overhead transmission lines can provide birds with scarce high-altitude habitats. High-altitude habitats not only provide a good view, but also facilitate birds to forage and nest. At the same time, high-altitude habitats can also protect birds from harm from land predators. Therefore, there is no doubt that overhead transmission lines will be affected by bird activities after they are erected; At present, overhead transmission lines mainly refer to transmission lines that are erected above the ground, in which transmission wires are fixed to poles and towers erected on the ground with insulators to transmit electrical energy. In addition to building nests on poles and towers, birds also like to stay on transmission lines. When a large number of birds stay on the transmission lines, the transmission lines are affected by the pressure of the birds' own weight, resulting in excessive bending arcs, and the tension at both ends of the transmission lines close to the poles and towers is greater, which will increase the stress of the transmission lines themselves. In the long run, the transmission lines may suffer mechanical damage due to excessive tension and load, thereby increasing the risk of wire breakage or loosening, and also affecting the integrity of the wires in the transmission lines and the stability of power transmission, thereby increasing the frequency and cost of transmission line maintenance.

[0014] Compared with the prior art, the present invention provides a transmission line bird repellent, which has the following beneficial effects: The winding drum is driven to rotate by the transmission line body, so that the two contacts located inside the belt rotating part come into contact with each other and connect the circuit of the servo motor, so that it drives the winding drum to reverse and reel in the previously extended transmission line body, and then the two are separated from each other by the mutual attraction between magnet one and magnet two and the block, and magnet two is reset by the elastic rope, thereby avoiding the problem of too many birds staying on the transmission line body causing the transmission line body to bend too much, thereby reducing the risk of damage to the transmission line body, thereby ensuring the integrity of the wire and the stability of power transmission, and at the same time reducing the number of repairs for wire damage caused by bird activities, thereby reducing the maintenance cost of the power company.

[0015] The reciprocating retracting and extending mechanism causes the transmission line body to perform an up and down reciprocating floating motion, thereby shaking the ice cones condensed on the surface of the transmission line body in cold winter weather, causing the ice cones on the surface to fall off, reducing the weight of the ice cones on the transmission line body, and further reducing the risk of increased transmission line tension and line breakage due to excessive ice load, thereby reducing the mechanical damage to the transmission line body caused by the ice cones, thereby extending the service life of the transmission line body.

[0016] The connecting plate is driven by the transmission line body to slide back and forth up and down along the inside of the fixed frame, prompting the multiple swing rods and meteor balls on the connecting rod to move up and down and rotate horizontally, thereby reducing the staying space of birds on the transmission tower, and then keeping the birds away from the transmission tower, thereby effectively preventing birds from building nests on the transmission tower, reducing the possibility of them building nests on the tower, and at the same time effectively reducing the probability of discharge tripping accidents in the transmission line.

[0017] The friction wheel is driven to rotate by the falling of the transmission line body, and the friction wheel is driven to rotate in the opposite direction by the torque force of the torsion spring, so that the reciprocating screw can rotate in both directions, and then the binding wire and the transmission line body can be continuously tightened, avoiding the problem of increase in the gap between the transmission line body and the insulator due to the falling of the transmission line body, ensuring the close connection between the transmission line body and the insulator, thereby ensuring the electrical insulation performance of the transmission line body, and improving the safety and stability of power transmission.

[0021] The present invention is further described in detail below based on the accompanying drawings and embodiments.

[0022] Example 1: Please refer to Figures 1 to 8As shown, in order to solve the problems mentioned in the technical solution, an embodiment of the present application provides a transmission line bird repellent, including a mounting base 1, whereby the mounting base 1 can be fixedly mounted on a transmission tower. Specifically, the mounting base 1 is mounted on the tower of the transmission line by means of threads and screws. No less than two mounting bases 1 are provided, and a transmission line body 101 is provided above the two mounting bases 1.

A mounting seat 2 is fixedly connected to one side near the top of the mounting base 1, and a winding drum 201 is rotatably connected to the opposite surface of the mounting seat 2. The transmission line body 101 is wound on the outer surface of the winding drum 201, and a connecting column 202 is fixedly connected to the opposite surface of the mounting seat 2, wherein the connecting column 202 is located inside the winding drum 201, and the central axes of the two coincide with each other. A sliding groove 203 is provided on the outer surface of the connecting column 202, and a belt rotating member 204 is fixedly connected to the inner surface of the winding drum 201, and the connecting column 202 is arranged inside the belt rotating member 204. A spiral limiting groove is arranged inside the belt rotating member 204, and both ends of the spiral limiting groove are in the same horizontal plane with the central axis of the connecting column 202. A transmission rod 205 is slidably connected in the limiting groove provided inside the belt rotating member 204, and the other end of the transmission rod 205 is slidably connected inside the slide groove 203. A magnet 1 206 is fixedly connected to the bottom of the transmission rod 205, and a magnet 2 207 is slidably connected inside the side of the belt rotating member 204 away from the transmission rod 205, wherein the bottom of the magnet 2 207 is engaged with the bottom of the inner cavity of the side of the belt rotating member 204 away from the magnet 1 206, and when no external force is applied, the magnet 2 207 is always in a preset position and will not move. The magnetism of the magnet 2 207 is opposite to that of the magnet 1 206, and contacts 208 are fixedly connected to both the magnet 2 207 and the magnet 1 206.

[0023] A driving assembly is disposed on the outer surface of the connecting column 202. The driving assembly includes a servo motor 209, which is installed inside the winding drum 201. A driving gear 210 is installed on the output shaft of the servo motor 209. An internal gear 211 is fixedly connected to the inner surface of the winding drum 201, and the internal gear 211 is meshed with the driving gear 210. The contacts 208 are in electrical contact with each other and the opening and closing of the servo motor 209 is controlled by a controller.

[0024] A reset assembly is provided on the second magnet 207. The reset assembly includes an elastic rope 2071, one end of which is fixedly connected to the bottom of the second magnet 207, wherein the diameter of the elastic rope 2071 is greater than the length of the inner ring opening of the belt rotating member 204, and a stopper is fixedly installed on the other end of the elastic rope 2071, and the stopper is located outside the belt rotating member 204, and a stopper 2072 is fixedly connected to the belt rotating member 204 through a groove, and the two sides of the second magnet 207 are slidably connected to the inside of the groove, and the first magnet 206 is slidably connected to the limiting groove on the belt rotating member 204, and the two sides of the first magnet 206 do not contact the inside of the groove, so the stopper 2072 is located on the movement trajectory of the second magnet 207, while the stopper 2072 is not located on the movement trajectory of the first magnet 206.

[0025] Working process: When constructing a transmission line, the power workers first install the mounting base 1 on the transmission tower, and then wind the transmission line body 101 on the outer surface of the winding drum 201. When birds fly to the transmission line body 101 between two transmission towers, as the number of birds staying on the transmission line body 101 gradually increases, the pressure on the transmission line body 101 gradually increases, causing it to fall vertically as a whole. At this time, the transmission line body 101 wound on the winding drum 201 is continuously pulled, causing the winding drum 201 to rotate inside the mounting seat 2, and driving the belt rotating member 204 to rotate. When the belt rotating member 204 rotates, The slide groove squeezes the transmission rod 205 located inside it, and the transmission rod 205 is driven to move along the slide groove 203 under the limiting action of the slide groove 203. At the same time, the transmission rod 205 drives the magnet 1 206 and the contact 208 thereon to move synchronously, and gradually approaches the magnet 2 207 at the other end of the rotating member 204. When the contact 208 on the transmission rod 205 contacts the contact 208 on the magnet 2 207, the magnet 1 206 and the magnet 2 207 on the transmission rod 205 contact each other and attract each other by means of magnetism, so that the subsequent movement of the magnet 1 206 will drive 207 to move synchronously. In addition, when the contacts 208 contact each other, a passage is formed, so that the circuit of the servo motor 209 is connected, and the servo motor 209 is controlled by the controller to drive the driving gear 210 to rotate, and the driving gear 210 rotates in the opposite direction to the winding drum 201. Then the driving gear 210 drives the internal gear 211 meshing with it to rotate, thereby driving the winding drum 201 to rotate in the opposite direction, thereby the stretched transmission line body 101 can be rolled up, so that the transmission line body 101 that falls due to the gravity of a large number of birds gradually moves upward and gradually tends to a straightened state. In this process, some birds can be driven away from the transmission line body 101.

[0026] When the winding drum 201 rotates in the reverse direction, it drives the rotating member 204 to rotate in the reverse direction synchronously. During this process, the transmission rod 205 slides in the reverse direction along the inside of the slide groove 203, and through the attraction between magnet 1 206 and magnet 2 207, the transmission rod 205 drives magnet 2 207 and the contact 208 thereon to move synchronously through magnet 1 206. It is worth mentioning that at this time, since magnet 1 206 and magnet 2 207 are always attracted to each other through magnetism, the contact 208 is always in a state of contact with each other. The elastic rope 2071 on the second magnet 207 moves synchronously with the second magnet 207 and continuously extends into the limiting groove on the belt rotating member 204. When the elastic rope 2071 is completely extended into the belt rotating member 204, the stop block located outside the belt rotating member 204 conflicts with the belt rotating member 204, so that the end of the elastic rope 2071 in contact with the stop block cannot enter the limiting groove. Therefore, the elastic rope 2071 is gradually stretched by the traction of the second magnet 207. When the second magnet 207 moves to contact the stop block 2072 located inside the slide rail belt rotating member 204, the stop block 2072 blocks the movement trajectory of the second magnet 207, making it unable to move synchronously with the transmission rod 205. Since the first magnet 206 does not contact the stop block 2072, it can continue to move synchronously with the transmission rod 205 until the second magnet 207 is separated from the first magnet 206. At this time, the elastic rope 2071 loses its restriction and under the action of its elastic force, it drives the second magnet 207 and the contact 208 thereon to gradually reset, and the circuit of the servo motor 209 is disconnected, so that it stops rotating, and the reel 201 also stops reeling the transmission line body 101. The gravity of some birds that have not yet flown away on the transmission line body 101 continues to squeeze the transmission line body 101 to make it fall, and the transmission line body 101 continuously floats up and down, making it impossible for birds to stay on the transmission line body 101. This can avoid the problem of too many birds staying on the transmission line body 101 causing the transmission line body 101 to bend too much, and thus reduce the risk of damage to the transmission line body 101, thereby ensuring the integrity of the wire and the stability of power transmission, and at the same time reducing the number of repairs for wire damage caused by bird activities, thereby reducing the maintenance cost of the power company. In addition, when there are a small number of birds, their impact on the transmission line is small, and it will not be triggered at this time, so there is no need to run this device continuously or frequently, which is in line with practical applications.

[0027] Example 2: Please refer to Figures 9 to 11As shown, a reciprocating lifting mechanism is arranged at the middle of the top of the mounting base 1, and the reciprocating lifting mechanism comprises a fixing frame 3, which is fixedly connected to the middle of the top of the mounting base 1, and a connecting plate 301 is slidably connected in the fixing frame 3, and a limiting hole is provided in the connecting plate 301. When the transmission line body 101 is installed, it is plugged into the connecting plate 301 through the limiting hole, and the size of the limiting hole is larger than the size of the transmission line body 101, so that the transmission line body 101 can be limited by the limiting hole while allowing it to slide in the limiting hole. A connecting rod 302 is rotatably connected to the top of the connecting plate 301, and a spiral groove 303 is provided on the outer surface of the connecting rod 302. A channel is provided at the top of the fixing frame 3, and the connecting rod 302 is plugged into the inside of the channel, and a limiting ball 304 is fixedly connected to the side wall of the channel, wherein, when the connecting rod 302 is plugged into the inside of the channel, the limiting ball 304 is slidably connected to the inside of the spiral groove 303. The limiting ball 304 is adapted to the spiral groove 303. A plurality of swing rods 305 are fixedly connected to the top of the connecting rod 302 at equal distances, and a meteor ball 306 is fixedly connected to the bottom of the plurality of swing rods 305 on one side away from the connecting rod 302 .

[0028] Working process: When the transmission line body 101 falls due to the gravity of the bird, the transmission line body 101 drives the connecting plate 301 to slide down along the fixing frame 3 synchronously, and the connecting rod 302 also slides down synchronously. During this process, the limiting ball 304 on the fixing frame 3 is always fitted inside the spiral groove 303 on the connecting rod 302, and continuously squeezes the spiral groove 303, causing the connecting rod 302 to rotate, thereby allowing the connecting rod 302 to rotate laterally while moving up and down with the connecting plate 301. At this time, the connecting rod 302 drives the multiple swing rods 305 thereon to rotate synchronously, and the meteor balls 306 on the multiple swing rods 305 are offset with the rotation of the swing rod 305, and gradually tilt toward the outside of the swing rod 305. As the swing rod 305 rotates continuously, the meteor ball 306 gradually tends to an inclined state from a vertical state. When the transmission line body 101 moves upward due to the winding of the winding drum 201, similarly, the transmission line body 101 drives the connecting plate 301 and the connecting rod 302 thereon to move vertically upward, and under the mutual cooperation of the limiting ball 304 and the spiral groove 303, the multiple swing rods 305 and the meteor ball 306 are again caused to move up and down and rotate horizontally, thereby reducing the staying space of birds on the transmission tower, and then the birds can be kept away from the transmission tower, thereby effectively preventing birds from building nests on the transmission tower, reducing the possibility of them building nests on the transmission tower, and at the same time effectively reducing the probability of discharge tripping accidents in the transmission line.

[0029] Example 3: Please refer to Figure 4 , Fig. 9 , Fig.11 as well as Fig.12As shown, an automatic tightening mechanism is provided on one side of the top of the mounting base 1 , and the automatic tightening mechanism includes a second mounting seat 4 , which is mounted on the top of the mounting base 1 , and a friction wheel 401 is rotatably connected to the second mounting seat 4 .

[0030] Preferably, the outer surface of the friction wheel 401 is made of rubber material, which is used to increase the friction between the friction wheel 401 and the transmission line wheel.

[0031] The friction wheel 401 is arranged on the erection path of the transmission line body 101, and the outer surface of the transmission line body 101 is in contact with the opposite surface of the friction wheel 401, and a torsion spring 402 is fixedly connected between the friction wheel 401 and the mounting seat 2 4. A reciprocating screw 403 is fixedly connected to one end of the friction wheel 401, and the reciprocating screw 403 is located outside the mounting seat 2 4, and a nut 404 is threadedly connected to the outer surface of the reciprocating screw 403, and a tightening rope 405 is symmetrically slidably connected to one side of the top of the mounting base 1, and there are no less than two tightening ropes 405, wherein the thread length of the reciprocating screw 403 is consistent with the length of the intersection of the multiple tightening ropes 405, thereby limiting and avoiding the problem of the tightening rope 405 shrinking too tight and causing damage to the transmission line body 101. Two tightening ropes 405 are sleeved on the outside of the insulator 102, and the tightening ropes 405 are located on the outer surface of the tie wire 103, thereby ensuring that the tightening ropes 405 can tighten the tie wire 103 and the transmission line body 101 at the same time. The ends of the two tightening ropes 405 away from the insulator 102 are in contact with each other, and the ends of the two tightening ropes 405 away from the insulator 102 are fixedly connected to the top of the mounting base 1, and the outer surfaces of the two tightening ropes 405 that are in contact with each other are slidably connected to a push-pull plate 406, and one side of the push-pull plate 406 is fixedly connected to the nut 404.

[0032] Working process: The initial state when there are no birds resting on the power transmission line body 101: the power transmission line body 101 is not in contact with the outer surface of the friction wheel 401, and the nut 404 and the push-pull plate 406 thereon are located on the side of the reciprocating screw 403 away from the friction wheel 401, therefore, the two tightening ropes 405 located outside the tie wire 103 are in a relaxed state without being tightened by the push-pull plate 406. During the falling of the transmission line body 101 due to the gravity of the bird, the transmission line body 101 squeezes the insulator 102 downward, and the binding wire 103 is loosened by the squeezing force of the transmission line body 101, thereby increasing the gap between the transmission line body 101 and the insulator 102. At the same time, the outer surface of the transmission line body 101 contacts the outer surface of the friction wheel 401, and the friction force between the two is pulled to cause the friction wheel 401 to rotate. At this time, the torsion spring 402 on the mounting seat 24 is contracted by the force, and the friction wheel 401 drives the reciprocating screw 403 to rotate, causing the nut 404 on the reciprocating screw 403 to move along its surface toward the insulator 102, and drives the push-pull plate 406 on one side of the nut 404 to move in the same direction, so that the multiple tightening ropes 405 are constantly approaching and fitting each other, thereby tightening the tightening rope 405 located outside the insulator 102. When the transmission line body 101 moves upward due to the winding of the winding drum 201, The transmission line body 101 gradually separates from the friction wheel 401. At this time, the torsion spring 402 loses its restriction and gradually returns to its original state. The torque force thereof drives the friction wheel 401 and the reciprocating screw 403 to rotate in the opposite direction, and prompts the nut 404 on the reciprocating screw 403 to move along its surface toward the insulator 102 again, thereby tightening the tightening rope 405 located outside the insulator 102 again, and then continuously tightening the binding wire 103 and the transmission line body 101, thereby avoiding the problem of the transmission line body 101 falling and causing the gap between it and the insulator 102 to increase, and ensuring the close connection between the transmission line body 101 and the insulator 102. In other words, compared with the existing device that always keeps the tightening state by the tightening rope 405, the present device can directly achieve the same tightening effect by means of the binding wire 103, and when the binding wire 103 is loosened, the tightening rope 405 automatically shrinks to achieve the purpose of fixing the transmission line body 101. This ensures the electrical insulation performance of the transmission line body 101 and improves the safety and stability of power transmission.
