Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of clearing obstacles of transmission and distribution network lines, and in particular to an automatic clearing device and method for transmission and distribution network lines. Background Art
[0002] When designing the transmission and distribution network lines, their electrical parameters (such as resistance, capacitance, etc.) are calculated based on the situation where there are no obstacles. When there are obstacles, the electric and magnetic field distribution of the lines will change, which will in turn affect the electrical performance of the lines. Therefore, it is necessary to remove the obstacles on the transmission and distribution network lines.
[0003] When wind blows through the transmission line, the conductors are prone to dancing, making it easy for conductors close to each other to collide. The spacer, through its geometric shape and connection structure, fixes each sub-conductor in a relatively stable position, just like a frame, to prevent the sub-conductors from colliding and wearing each other. The spacers are firmly fixed on the transmission lines, thus building an extremely stable support structure for the bird's nest. Compared with natural branches, the spacers produce very little shaking under the influence of natural factors such as wind and rain. Birds such as magpies and crows are good at building large and complex nests. They use a lot of branches, soil and other materials in the process of nesting, which urgently requires a solid and stable foundation to bear the weight of the entire nest, and the spacers can perfectly meet this key demand. For this reason, bird nests are often found on spacers in daily life; It is impossible to seal the gaps in the spacers to prevent birds from building nests. This is because the wind is strong at high altitudes. If the gaps in the middle of the spacers are blocked, the force-bearing area of the spacers will increase, causing the wind to have a greater impact on the spacers. At present, there are many ways to remove bird nests, including manual removal, tool-assisted removal, and laser removal. Manual removal requires workers to climb up the tower to remove the bird's nest manually, which poses a risk of falling or electric shock. Tool-assisted removal uses a long-pole tool with a hook or shovel installed on the pole head to hook the bird's nest material and pull it down. The long-pole tool is limited in length and cannot reach bird's nests that are too high or too far away. Laser removal is to burn the bird's nest by emitting lasers, but it requires precise control of the laser's energy and emission direction, which places extremely high demands on the operator. A slight deviation may cause damage to the transmission line itself. However, these methods also have a common flaw, which is that they rely on manual operation and cannot detect the existence of bird nests in time. The materials of bird nests are mainly branches, hay, soil, etc., which are all conductors. When it rains, is humid, or there is conductive dust attached, the bird nest will become a conductive channel; once the conductive material in the bird nest contacts the different phase conductors of the transmission line or between the conductors and the pole tower, it will cause the line to short-circuit, causing the transmission line to trip, affecting the normal transmission of electricity.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0020] The present invention provides a technical solution: See also Figure 1-Figure 7 As shown, an automatic obstacle clearing device for a transmission and distribution network line includes a line body 1 and a spacer bar body 4, and also includes a base 5, which is installed on the top of the spacer bar body 4, and a mounting hole body 3 extending vertically up and down and penetrating its side wall is opened on the base 5, and a connecting rod 6 is slidably connected in the mounting hole body 3, and the bottom end of the connecting rod 6 extends into the spacer bar body 4; a reset member is connected between the connecting rod 6 and the mounting hole body 3, which is used to provide a reset force for the connecting rod 6 after sliding; The swing rod 2 is vertically arranged in the mounting hole body 3, and the top end of the swing rod 2 passes through the top end of the mounting hole body 3 and extends upward. The bottom end of the swing rod 2 is close to or fits with the top end of the connecting rod 6, and is used to squeeze the connecting rod 6 to produce vertical reciprocating movement after the swing rod 2 swings under the action of wind turbulence.
[0021] The bottom end of the base 5 is fixedly connected to the top of the spacer body 4, and a part of the connecting rod 6 is located in the mounting hole body 3 of the base 5, and the bird's nest is inside the spacer body 4, so the bottom end of the connecting rod 6 is located inside the spacer body 4, that is, close to the bird's nest, the bottom end of the pressure rod 14 is against the top of the connecting rod 6, and the top end of the pressure rod 14 is against the outer wall of the chassis 17; First, Figure 2 It is shown in the figure that the area of the swing rod 2 after it extends out of the base 5 is exposed to the air, and the area of the swing rod 2 outside the base 5 accounts for eight tenths of the length of the swing rod 2 itself. When the wind in the high altitude flows through the swing rod 2, turbulence will be generated. On the windward side of the swing rod 2, the air flow rate will decrease and the pressure will increase; on the leeward side, the air will form a vortex and the pressure will decrease. This pressure difference will generate a lateral force, pushing the swing rod 2 to swing toward the leeward side. Therefore, when the wind blows the swing rod 2, the bottom end of the swing rod 2 will also swing. When swinging, the bottom end of the swing rod 2 will move in a circular arc trajectory, and push and squeeze the top end of the connecting rod 6 during the movement, so that the connecting rod 6 moves downward, and the downward movement of the connecting rod 6 will hit the bird's nest, thereby destroying the balance of the bird's nest structure and causing the branches of the bird's nest to loosen and collapse; It is worth noting that the swing of the swing stick 2 can only be triggered when the wind is strong. This is because when the swing stick 2 is in a stationary state, it is affected by multiple forces such as its own gravity and the bottom support force. These forces are in a balanced state. There is static friction at the contact point between the bottom and the support surface. This static friction will generate a friction torque that resists the rotation of the rod. The wind force generated by a small wind is small, and the product of the torque force and the lever arm generated by the small wind is smaller than the static friction torque and the resistance torque generated by the structure of the swing rod 2 itself. The torque that resists rotation is determined by factors such as the material, shape, and installation method of the rod. For example, a metal rod with a large mass and a solid bottom installation has a large resistance torque of its own. The weak torque generated by the small wind is not enough to break this balance, so that the swing rod 2 will not swing; Birds will not build nests when there is wind or the wind is strong, because the wind will blow down the branches and other materials used to build the bird's nest. Therefore, birds will choose to build bird's nests when the wind is small or there is no wind. The swing rod 2 will move the connecting rod 6 downward when a relatively strong wind is generated, thereby destroying the bird's nest.
[0022] See also Figure 3-Figure 7 The mounting hole body 3 is divided into a first mounting hole 301 and a second mounting hole 302 from bottom to top, and the inner diameter of the second mounting hole 302 is larger than the inner diameter of the first mounting hole 301; The trigger member at least includes a chassis 17 vertically arranged in the second mounting hole 302 , the upward orthographic projection area of the chassis 17 is larger than the orthographic projection area of the swing rod 2 , and the bottom end of the chassis 17 is close to or in contact with the top end of the connecting rod 6 .
[0023] look Figure 4 and Figure 5 In the embodiment, the top of the base 5 is rounded, so that the second mounting hole 302 has a wider space than the first mounting hole 301, in order to provide a swingable space for the chassis 17. Figure 4 From the perspective of , the swing of the swing rod 2 will drive the chassis 17 to swing together. When the chassis 17 swings, the edge of the chassis 17 will continue to approach the top of the connecting rod 6 in the tilting process, and then in the process of approaching, the inclined surface of the chassis 17 will continue to press the top of the connecting rod 6 downward, so that the connecting rod 6 moves downward; Since the chassis 17 is larger than the swing rod 2, the swing area of the edge of the chassis 17 is also larger than the bottom of the swing rod 2. In this way, after the chassis 17 swings, the edge of the chassis 17 will push the connecting rod 6 downward further due to the higher swing amplitude.
[0024] See also Figure 4-Figure 7 A plurality of pressure rods 14 are arranged in the first mounting hole 301. The pressure rods 14 are vertically arranged above the connecting rod 6. The plurality of pressure rods 14 are arranged at equal intervals along the circumferential track of the connecting rod 6. The bottom end of the pressure rod 14 is connected to the top end of the connecting rod 6. The pressure rod 14 extends obliquely from above the connection between the first mounting hole 301 and the second mounting hole 302 toward the edge of the chassis 17 , and approaches or abuts against it.
[0025] When the chassis 17 swings, the edge of the chassis 17 will continuously approach the top of the pressure rod 14 while tilting, and then in the process of approaching, the inclined surface of the chassis 17 will continuously press the pressure rod 14 downward, so that the pressure rod 14 moves downward, and after the pressure rod 14 moves downward, it will push the connecting rod 6 to move downward together. Since the swing rod 2 will swing regardless of the direction of the wind, multiple pressure rods 14 can squeeze at least one pressure rod 14 regardless of the direction in which the chassis 17 tilts and swings, and then the pressure rod 14 moves downward to drive the connecting rod 6 to hit the bird's nest; Since the chassis 17 is pressing the pressure rod 14 downward while tilting, the chassis 17 will also generate a thrust force on the pressure rod 14 toward the inner walls of the second mounting hole 302 and the first mounting hole 301 during the tilting process, so that the pressure rod 14 is close to the inner walls of the second mounting hole 302 and the first mounting hole 301. If the pressure rod 14 is directly extended to the outside of the base 5 to poke the bird's nest, then when the chassis 17 tilts and pushes the pressure rod 14, the pressure rod 14 will tilt toward the inner wall of the first mounting hole 301, and then the outer wall of the pressure rod 14 will slide against the inner wall of the first mounting hole 301, which will provide resistance to the movement of the pressure rod 14, thereby offsetting the force of the pressure rod 14 moving downward; exist Figure 5It can be seen that a circular opening 15 is provided between the first mounting hole 301 and the second mounting hole 302, and the pressure rod 14 originally in the mounting hole body 3 extends upwardly from the circular opening 15, so that the corner of the pressure rod 14 is above the circular opening 15, so that when the chassis 17 applies an inclined pressure to the pressure rod 14, this force will be transmitted along the inclined part of the pressure rod 14, and there is a corner between the inclined part of the pressure rod 14 and the vertical part located in the first mounting hole 301, and this corner is located above the circular opening 15, and then when this force reaches the corner of the pressure rod 14, it will cause the corner of the pressure rod 14 to be slightly deformed, specifically, the inclined part of the pressure rod 14 is swung downward from the corner, but the tiltable range is limited, and the inclined part of the pressure rod 14 will not contact the inner wall of the circular opening 15 and the second mounting hole 302; This part of the deformable shape can offset part of the lateral thrust exerted by the chassis 17 on the pressure rod 14. When the chassis 17 exerts a lateral thrust on the pressure rod 14, the corner of the pressure rod 14 deforms in a small range, causing the inclined part of the pressure rod 14 to tilt downward for a short distance, and then the entire pressure rod 14 will continue to move downward, and then the pressure rod 14 will drive the connecting rod 6 to move downward, retaining the force of the pressure rod 14 hitting the connecting rod 6 downward; There is a gap between the inclined portion of the pressure rod 14 and the connection between the first mounting hole 301 and the second mounting hole 302 , and the gap allows the inclined portion of the pressure rod 14 to move downward together with the pressure rod 14 .
[0026] See also Figure 2-Figure 5 Two elastic plates 16 are disposed in the second mounting hole 302. The elastic plates 16 are hollow. The two elastic plates 16 are respectively located at the top and bottom of the chassis 17; The top of the second mounting hole 302 is provided with an outlet 18 for the swing rod 2 to extend out, the diameter of the outlet 18 is smaller than the diameter of the swing rod 2, and there is a gap between the outer wall of the swing rod 2 and the inner wall of the outlet 18; The swing rod 2 is inserted through the elastic plate 16 above the chassis 17 and extends to the outside of the mounting hole body 3. The elastic plate 16 below the chassis 17 is provided with a plurality of sliding holes 26. The plurality of sliding holes 26 are arranged in the same trajectory as the plurality of pressure rods 14. The top end of the pressure rod 14 is inserted through the sliding hole 26 and abuts against the bottom of the chassis 17. The inner wall of the sliding hole 26 is fixedly connected to the outer wall of the pressure rod 14.
[0027] The swing rod 2 extends to the outside of the base 5 through the outlet 18. The outlet 18 does not contact the swing rod 2 and a gap is left. The purpose of the gap is to provide space for the swing rod 2 to swing. Figure 5As can be seen, the interior of the elastic plate 16 is hollow, and the chassis 17 is located between the two elastic plates 16. Since the elastic plate 16 itself is made of elastic material, specifically, a resilient material such as steel or titanium alloy can be used. The two elastic plates 16 squeeze the chassis 17 tightly in the middle. When the chassis 17 swings, the elastic plate 16 is squeezed and shrinks and deforms in the second mounting hole 302. Therefore, the elastic plate 16 plays a role in supporting the chassis 17 and the swing rod 2. The swing rod 2 is inserted through the upper elastic plate 16. Therefore, after the upper elastic plate 16 shrinks inwardly, the side corresponding to the swing rod 2 will slide along the outer wall of the swing rod 2. There is a gap between the swing rod 2 and the inner wall of the elastic plate 16. This gap provides a moving distance for the elastic plate 16 after deformation. The pressure rod 14 is inserted through the elastic plate 16 below and contacts the outer wall of the chassis 17. The elastic plate 16 below the chassis 17 is provided with sliding holes 26 with the same number as the pressure rod 14 for the pressure rod 14 to be inserted, and the pressure rod 14 is fixedly connected to the sliding holes 26. Therefore, when the chassis 17 swings and squeezes the pressure rod 14, the elastic plate 16 will also deform together, and after the elastic plate 16 rebounds, it can also pull the pressure rod 14 back to its original position, so that the pressure rod 14 can continuously drive the connecting rod 6. A fixing rod 20 is fixedly installed on the top of the connecting rod 6. The fixing rod 20 is located between multiple pressure rods 14, so that the movement of the pressure rod 14 can be more stable, further preventing the pressure rod 14 from bending and deforming excessively inward when being squeezed.
[0028] See also Figure 3-Figure 7 , an extrusion rod 7 is fixedly mounted on the bottom end of the connecting rod 6; Two elastic rods 10 are arranged below the connecting rod 6, and the two elastic rods 10 are arranged crosswise. The extrusion rod 7 is located at the intersection of the two elastic rods 10, and the outer wall of the extrusion rod 7 is against the outer wall of the elastic rod 10. The elastic rod 10 is arc-shaped, and there is a gap between the two elastic rods 10; Both ends of the elastic rod 10 are connected to sliding rods 11 , a sleeve 9 is sleeved between the two sliding rods 11 , corresponding ends of the two sliding rods 11 extend into the inside of the sleeve 9 , and a fixing frame 8 is connected between the sleeve 9 and the spacer rod body 4 .
[0029] When the connecting rod 6 moves downward, it drives the squeezing rod 7 to move downward together and squeeze the two elastic rods 10. The elastic rod 10 is also made of elastic and deformable material. The elastic rod 10 can use the same material as the elastic plate 16. The initial shape of the elastic rod 10 is arc-shaped. When the squeezing rod 7 squeezes the elastic rod 10, the elastic rod 10 will deform in the direction of the sliding rod 11, and then the two ends of the elastic rod 10 will expand outward. The bird's nest is located inside the spacer rod body 4. Since the bird's nest is bowl-shaped, the bird's nest will be surrounded by the outer periphery of the elastic rod 10, and the elastic rod 10 will be close to the inside of the bird's nest. The initial shape of the elastic rod 10 is small and bent into a shape similar to a semicircle. The angle of the elastic rod 10 is inclined, and one end of the two elastic rods 10 faces the lower right corner and the lower left corner of the bird's nest respectively, and the other end faces the upper right corner and the upper left corner of the bird's nest; When the elastic rod 10 is squeezed downward by the squeezing rod 7, the elastic rod 10 is deformed in the direction of the sleeve 9, and the two ends of the elastic rod 10 are inclined diagonally outward and hit the bird's nest, destroying the structure of the bird's nest from the inside out. The bird's nest is usually interwoven with multiple layers of branches, hay and other materials. The diagonal impact can cause these materials to move relative to each other between different layers. When one end of the elastic rod 10 hits the upper left corner of the bird's nest and the other end hits the lower right corner, the material in the middle layer of the bird's nest is squeezed and pulled in different directions, resulting in the destruction of the interwoven structure between the materials, and the internal support frame will also loosen, thereby promoting the collapse of the structure of the entire bird's nest; like Figure 3 From the perspective of FIG. 1 , both ends of the fixing frame 8 are fixedly connected to the outer wall of the spacer rod body 4, and the other end is fixedly connected to the outer wall of the sleeve 9, in order to ensure the stability of the sleeve 9. Figure 6 From the perspective of , one end of the sliding rod 11 is fixedly connected to the outer wall of the elastic rod 10, and the other end extends to the inside of the sleeve 9. The sharp end of the elastic rod 10 faces the bird's nest, which is convenient for insertion between the branches of the bird's nest.
[0030] See also Figure 3-Figure 6 A slider 23 is fixedly mounted on one end of the slide rod 11 extending to the inside of the sleeve 9 . A sliding cavity 22 is provided in the sleeve 9 . The slider 23 abuts against the inner wall of the sliding cavity 22 . A tension spring 24 is connected between the two sliders 23 .
[0031] by Figure 6 From the perspective of , when the elastic rod 10 is squeezed and contracted by the extrusion rod 7, the slider 23 and the end of the slide bar 11 connected to the slider 23 will slide along the sliding cavity 22. At this time, the two sliders 23 will move relative to each other, and the two sliders 23 will squeeze the tension spring 24. When the extrusion rod 7 moves upward to stop squeezing the elastic rod 10, the tension spring 24 will separate the two sliders 23, causing the two sliders 23 to move away from each other. At the same time, the elastic rod 10 will also use its own elasticity to rebound and pull the slide bar 11 to move part of the area out of the sleeve 9.
[0032] See also Figure 6 An insert rod 25 is fixedly installed on the outer wall of one of the sliders 23, and the other end of the insert rod 25 is inserted into the inside of the other slider 23 and the slide rod 11. The insert rod 25 is located inside the tension spring 24. Both ends of the sleeve 9 are provided with through openings 21, and the through openings 21 are connected to the sliding cavity 22. The slide rod 11 extends into the sliding cavity 22 through the through openings 21.
[0033] The insertion rod 25 is fixedly mounted on the outer wall of one of the sliders 23. When the two sliders 23 move relative to each other, the insertion rod 25 will be inserted into the other insertion rod 25 and the slide bar 11. At this time, the elastic rod 10 is in a contracted state. When the elastic rod 10 is squeezed and expanded, the insertion rod 25 will be pulled out from one of the slide bars 11 and the slider 23. It is worth noting that when the elastic rod 10 is stretched to the final shape, the insertion rod 25 is still inserted into the other slide bar 23 and the slide bar 11. The through hole 21 provides a space for the slide bar 11 to enter and exit the sliding cavity 22. The connection method of the insertion rod 25, the slider 23 and the slide bar 11 makes the slide bar 11 more stable and less likely to deform when moving, and also makes the tension spring 24 less likely to deform.
[0034] See also Figure 4-Figure 5 The reset member also includes a socket 19 provided on the base 5, a connecting rod 6 is slidably connected to the inner wall of the socket 19, a sliding plate 13 is fixedly mounted on the top of the connecting rod 6, and a bottom end of the pressure rod 14 is fixedly connected to the top of the sliding plate 13; A return spring 12 is connected between the bottom of the sliding plate 13 and the inner bottom wall of the base 5 .
[0035] The socket 19 provides space for the connecting rod 6 to enter and exit the base 5, so that the connecting rod 6 can slide along the inner wall of the socket 19 when moving up and down. The sliding plate 13 is larger than the circle diameter of the socket 19, so it can be ensured that the connecting rod 6 will not fall out of the socket 19. When the connecting rod 6 moves downward, the sliding plate 13 will move downward together, and when the sliding plate 13 moves downward, it will squeeze the return spring 12, so that the connecting rod 6 can automatically move upward back to its original position.
[0036] See also Figure 1-Figure 7 , a method having any of the above automatic obstacle clearing devices for transmission and distribution network lines.
[0037] First, prepare a suitable spacer body 4, whose model and specification must match the conductor model, voltage level and other parameters of the line body 1. For example, for a 500kV ultra-high voltage line, it is necessary to select a spacer body 4 that can withstand high voltage and adapt to large-section conductors; at the same time, prepare installation tools such as wrenches, screwdrivers, etc., then open the wire clamp of the spacer body 4, and put the conductor into the wire clamp. When putting the conductor in, make sure that the conductor is located in the center of the wire clamp to avoid friction between the conductor and the edge of the wire clamp, then use a wrench or other tools to tighten the wire clamp bolts according to the specified torque, and then the spacer body 4 can be installed.
