Description

Technical Field

[0001] The present invention belongs to the field of power maintenance devices, and in particular relates to a transmission tower bird's nest removal device based on an unmanned aerial vehicle (UAV) platform. Background Art

[0002] In the power system, transmission towers are an essential component of the grid and play a crucial role in power transmission. However, birds nesting and roosting on transmission towers is a common natural behavior, but this behavior poses a serious threat to the safe and stable operation of the power grid.

[0003] When building nests, birds collect various nesting materials, such as branches, grass stems, and wire, and also produce large amounts of guano. If these nesting materials, guano, and other debris come into contact with power lines, they can easily cause electrical accidents such as short circuits and explosions, resulting in significant economic losses for power companies and posing a potential threat to public safety.

[0004] Traditional bird nest removal methods rely primarily on manual labor, typically using tools like insulated operating rods to directly poke and pound the nests. This method is feasible for situations where overhead power lines have simple pole structures, low nest locations, and are easily removed. However, it has several drawbacks. Firstly, it is inefficient, requiring workers to expend considerable time and effort to remove a single bird nest. This, especially when dealing with a large number of nests, makes it difficult to meet the timeliness requirements of grid operations and maintenance. Secondly, it carries significant safety risks, as workers must approach transmission towers during this operation, exposing them to risks such as electric shock and falls. For some nests located higher up, workers may even need to climb the poles to remove them, which not only increases safety risks but also poses a risk of phase-to-phase short circuits due to improper operation during the climb, posing a secondary threat to grid safety.

[0005] With the rapid development and widespread adoption of drone technology, its application in the power industry is becoming increasingly widespread. For the removal of bird nests from transmission towers, several publicly available solutions have proposed using drones equipped with rotating cutters, flame chambers, and high-pressure nozzles to remove bird nests through cutting, burning, or the destruction of high-voltage insulating liquids. While these methods have improved the efficiency and safety of bird nest removal to some extent, they still present numerous challenges in practical application.

[0006] While using drones equipped with rotating blades to cut nests quickly can destroy nest structures, most birds have adapted to the presence of bird thorns and use them as a framework for nest construction. This makes the rotating blades susceptible to interference from the thorns during the cutting process, making it difficult to accurately and effectively cut the nest, resulting in poor nest removal results.

[0007] While using a flamethrower to remove bird nests can quickly destroy them, it carries a serious risk of fire. Transmission towers are often surrounded by a large amount of flammable material, such as hay and branches. If a fire gets out of control, it can cause immeasurable damage. Furthermore, the flamethrower process releases a large amount of burning debris, which can potentially cause secondary fires or harm the surrounding environment and personnel.

[0008] Using a high-pressure nozzle to spray high-voltage insulating liquid to break up bird nests is difficult to achieve in practice due to the high location of the nests. This unstable pressure leads to poor spraying and ineffective nest removal. Furthermore, all of the aforementioned bird nest removal methods can result in a large amount of nest material falling from the air, posing a risk of falling objects that could injure personnel or damage ground facilities.

[0029] The following will be combined with the Figures 1-10 The technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0030] In the description of the present invention, it should be understood that the terms "longitudinal", "transverse", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0031] like Figure 1 、 Figure 2 As shown, a transmission tower bird nest removal device based on a drone platform includes a support frame 1 and a spiral drilling lifting device 4, as shown in FIG. Figure 3 As shown, the support frame 1 is a frame structure formed by connecting a plurality of support cross bars 101 and support vertical bars 102. An opening is provided on one side of the lower portion of the support frame 1 for accommodating the tower head 7. like Figure 6 As shown, the spiral drilling lifting device 4 is used to lift the bird's nest, including a first vertical guide rail 405 installed on the supporting frame 1, and a third motor 407 is provided on the upper part of the first vertical guide rail 405, and a third screw 406 is connected to the output shaft of the third motor 407, and a third slider 408 is threadedly connected to the third screw 406, and the third slider 408 is slidably connected to the first vertical guide rail 405; a fourth motor 409 is installed on one side of the third slider 408, and an spiral drilling blade 410 is connected to the output shaft of the fourth motor 409.

[0032] During the bird's nest removal operation, the support frame 1 is lifted to the upper part of the tower head 7 by a drone, and the support frame 1 is lowered to the upper part of the bird's nest, and the third motor 407 and the fourth motor 409 are started. The third motor 407 drives the third slider 408 to move downward on the first vertical guide rail 405, thereby driving the fourth motor 409 and the spiral drilling blade 410 to move toward the bird's nest. The fourth motor 409 drives the spiral drilling blade 410 to rotate and makes the spiral drilling blade 410 drill into the bird's nest. Then the drone takes off again, lifts the bird's nest upward, separates the bird's nest from the tower, and realizes the removal operation of the bird's nest. During the removal process, since the bird's nest is lifted as a whole, the falling of the nest material is effectively avoided, eliminating the potential harm caused by the falling of the nest material to personnel and power transmission equipment, and ensuring the safe and stable operation of the transmission line.

[0033] like Figure 6 As shown, the spiral drilling blade 410 adopts a spiral cone structure or a spiral blade structure. When the spiral drilling blade 410 adopts a spiral blade, the edge of the spiral blade is designed to be a blade shape, ensuring that the spiral drilling blade 410 can smoothly drill into the bird's nest and can fix the bird's nest to the spiral drilling blade 410, preventing the bird's nest from falling from the spiral drilling blade 410.

[0034] like Figure 6 As shown, the support frame 1 is provided with a second motor 403, the output shaft of the second motor 403 is connected to a second lead screw 402, the second lead screw 402 is threadedly connected to a second slider 404, and the support frame 1 is also provided with a second transverse guide rail 401, the second slider 404 is slidably mounted on the second transverse guide rail 401, and the first vertical guide rail 405 is fixedly mounted on one side of the second slider 404.

[0035] The second motor 403 and the second lead screw 402 realize the adjustment of the position of the first vertical guide rail 405 and the spiral drilling blade 410, which is convenient for adjusting the position of the spiral drilling blade 410 according to the position of the bird's nest, thereby improving the accuracy of the bird's nest removal operation. When there are multiple bird's nests on the tower head 7, the multiple bird's nests can be drilled one by one by adjusting the position of the spiral drilling blade 410 laterally, thereby improving the efficiency of the operation.

[0036] like Figure 4 、 Figure 5 、 Figure 9 、 Figure 10 As shown, it also includes left and right limit devices 2, which are used to limit the support frame 1 in the left and right directions of the tower head 7. The left and right limit devices 2 include a first motor 204 symmetrically arranged on both sides of the support frame 1, and a first screw 203 is connected to the output shaft of the first motor 204. A first slider 205 is threadedly connected to the first screw 203. A first transverse guide rail 202 is provided on the upper part of the support frame 1, and the first slider 205 is slidably installed on the first transverse guide rail 202. An L-shaped limit rod 206 is fixedly connected to one side of the first slider 205, and the L-shaped limit rod 206 includes a limit horizontal rod and a limit vertical rod 201.

[0037] After the support frame 1 is placed on the tower head 7, the first motor 204 drives the first slider 205 on the first screw 203 to move toward the outside of the tower head 7, and abuts against the angle irons on both sides of the tower head 7, thereby realizing the limited fixation of the support frame 1 in the left and right directions of the tower head 7.

[0038] like Figure 7-10 As shown, it also includes a front and rear limiting device 3, which is used to limit the support frame 1 in the front and rear directions of the tower head 7. The front and rear limiting device 3 includes an electric push rod 301 fixedly installed at the lower end of one side of the support frame 1, and the telescopic rod end of the electric push rod 301 is connected with a U-shaped clamp 302 for docking with the cross bar on the tower head 7.

[0039] After the support frame 1 is placed on the tower head 7, the electric push rod 301 pushes the U-shaped clamping head 302 to move to the side of the horizontal bar of the tower head 7 and is clamped on the side of the horizontal bar, thereby realizing the limited fixation of the support frame 1 in the front and rear directions of the tower head 7. Together with the left and right limiting devices 2, the positioning of the support frame 1 on the tower head 7 is realized, ensuring the stability of the support frame 1 during the bird's nest removal operation.

[0040] like Figure 1-Figure 2 、 Figure 7-Figure 8 As shown, a lateral insertion and lifting device 5 is provided on one side of the support frame 1 for inserting the bird's nest laterally and lifting the bird's nest. The lateral insertion and lifting device 5 includes a mounting frame 505 installed on the rear side of the support frame 1, and a seventh motor 511 is installed on the mounting frame 505. The lower part of the seventh motor 511 is connected to a gear box 510. The gear box 510 adopts a dual-output structure, and a driving gear 512 is fixedly connected to the output shaft of the gear box 510. Guide sleeves 513 are provided on both sides of the gear box 510. A lifting rack 514 is slidably connected inside the guide sleeve 513. The distance between the lifting racks 514 on both sides is greater than the diameter of the spiral drilling blade 410. A rack 515 meshing with the driving gear 512 is provided on the upper part of the lifting rack 514.

[0041] After the spiral drilling blade 410 is inserted into the bird's nest from above, the seventh motor 511 drives the gear at the output shaft end of the gear box 510 to rotate, thereby driving the lifting bracket 514 at the bottom of the rack 515 to insert into the bird's nest from the side. The lateral lifting device cooperates with the spiral drilling lifting device 4 to remove the bird's nest from the tower head 7, further preventing the bird's nest from falling from the spiral drilling blade 410, and ensuring the stability of the bird's nest removal operation.

[0042] like Figure 7 As shown, the lifting rack 514 includes a moving rod and at least one insertion rod. In this embodiment, one insertion rod is provided. In other embodiments, the number of insertion rods can be flexibly set according to the size of the bird's nest. The rack 515 is fixedly mounted on the moving rod, and the insertion rod is detachably mounted on the end of the moving rod. Multiple insertion rods form a rake-like structure in the vertical direction.

[0043] The lifting rack 514 with a rake-like structure is inserted into the bird's nest from multiple points on the side of the bird's nest at the same time, which increases the contact area and gripping force between the lifting rack 514 and the bird's nest, ensures the stable lifting of the bird's nest, and improves the stability and reliability of the bird's nest lifting process.

[0044] like Figure 7-Figure 8As shown, a second vertical guide rail 501 is fixedly connected to one side of the support frame 1, and a fourth slider 504 is provided on one side of the mounting frame 505. The fourth slider 504 is slidably mounted on the second vertical guide rail 501. The second vertical guide rails 501 on both sides are rotatably connected with a fourth lead screw 502, and the upper end of the fourth lead screw 502 is fixedly connected to a transmission wheel 516, and the two transmission wheels 516 are connected by a synchronous belt 517; a fifth motor 503 is provided at the upper end of the second vertical guide rail 501 on one side, and the output shaft of the fifth motor 503 is connected to the fourth lead screw 502 on this side; the fourth lead screw 502 and the fourth slider 504 cooperate to realize the vertical position adjustment of the horizontal insertion lifting device 5, which is convenient for selecting a suitable horizontal insertion position according to the size of the bird's nest.

[0045] like Figure 7-Figure 8 As shown, a third transverse guide rail 506 is provided on one side of the mounting frame 505, a sixth motor 508 is provided on one side of the third transverse guide rail 506, a fifth lead screw 507 is connected to the output shaft of the sixth motor 508, a fifth slider 509 is threadedly connected to the fifth lead screw 507, the fifth slider 509 is slidably connected to the third transverse guide rail 506, and the gear box 510 is installed on the upper part of the fifth slider 509.

[0046] When the sixth motor 508 rotates, it drives the fifth screw 507 to rotate, and the fifth screw 507 drives the fifth slider 509 to move horizontally on the third transverse guide rail 506, thereby driving the transverse insertion lifting device 5 to adjust its position in the horizontal direction, so as to facilitate the adjustment of the position of the transverse insertion lifting device 5 according to the position of the bird's nest.

[0047] In addition, if Figure 1 、 Figure 2 As shown, as a conventional setting, in order to realize the control of multiple motors and the electric push rod 301, a controller 6 should also be provided on the support frame 1 to facilitate the ground workbench to control the bird's nest removal device. The controller 6 adopts a conventional structure that can be directly obtained by technical personnel in this field, and this application will not elaborate on the limitation.
