Description

Technical Field

[0001] The utility model relates to the field of wire deicing, in particular to an ice removal device for an overhead transmission line by an unmanned aerial vehicle (UAV). Background Technique

[0002] Overhead transmission lines are important facilities for transmitting electric energy in the power system. Since most of these lines are exposed, in cold weather, a layer of ice adheres to the outer wall of the line, increasing the weight of the wire, which may cause faults such as wire breakage and tower collapse, seriously affecting the normal transmission of electricity. Some workers will use an ice removal device for an unmanned aerial vehicle to remove the ice layer adhered to the outer wall of the overhead transmission line.

[0003] After retrieval, the Chinese patent publication number: CN221202106U discloses an ice removal device for a power grid overhead transmission line cable, including an unmanned aerial vehicle and an ice removal component arranged below the fuselage of the unmanned aerial vehicle. The unmanned aerial vehicle is used to transport the ice removal component above the cable, and a protective cover is fixedly installed on the lower surface of the fuselage of the unmanned aerial vehicle. Through the setting of the ice removal component, the unmanned aerial vehicle is first flown above the cable by a remote control device, the first motor is started, the first motor drives the driving bevel gear to rotate, the driving bevel gear drives the driven bevel gear to rotate, and then the driven bevel gear drives the lead screw to rotate. The lead screw nut drives the mounting frame to move along the axis of the lead screw, and the two ice removal wheels approach each other and clamp the cable. At this time, the rotor of the unmanned aerial vehicle stops working, the second motor is started, the second motor drives the ice removal wheel to rotate, the ice removal wheel drives the whole device to move along the cable, and while the ice removal wheel rotates, the pressing block continuously presses the ice and snow covering the cable, causing the ice and snow to break and separate to achieve the effect of ice removal.

[0004] In the above technology, through its designed structure, although there are certain improvements, when it is used, the ice layer adhered to the outer wall of the wire is processed through the cooperation of the ice removal wheel and the extrusion block. For a relatively thick or hard ice layer, one extrusion may only cause cracks on the surface of the ice layer and cannot be separated, and it is necessary to repeatedly extrude, resulting in too low ice removal effect. In addition, each group of ice removal wheels is controlled by a separate motor. In a low-temperature environment, the rotation speeds of multiple motors may be affected to varying degrees, resulting in the inability of each group of ice removal wheels to run synchronously, reducing the ice removal effect. Therefore, an ice removal device for an overhead transmission line by an unmanned aerial vehicle is proposed to solve the above problems. Content of the Utility Model

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] Refer to Figure 1 , Figure 3 - Figure 4 , an embodiment provided by the present invention: An ice removing device for an overhead transmission line drone, including a drone main body 1. The drone main body 1 is a prior art and can be realized by those skilled in the art. Since it is a prior art, it will not be described in detail in this case. The lower surface of the drone main body 1 is fixedly connected with a bracket 2 by bolts. Using bolts to fix the bracket 2 below the drone main body 1 facilitates the removal of the bracket 2 for overhauling the internal structure, and at the same time facilitates the installation of other devices on the drone main body 1 for use, improving the practicability. The lower surface of the bracket 2 is provided with an ice removing component, the upper surface of the bracket 2 is provided with a hammering component, and the right surface of the bracket 2 is provided with an adjusting component. The hammering component includes a motor 1 32. Both the motor 1 32 and the motor 2 51 are prior arts and can be realized by those skilled in the art. Since they are prior arts, they will not be described in detail in this case. The motor 1 32 is fixedly connected to the upper surface of the bracket 2, and the left surface of the motor 1 32 is fixedly connected with a round rod 33. The left surface of the round rod 33 is fixedly connected with a rotating plate 34.

[0032] Refer to Figure 1 - Figure 3, the de-icing assembly includes a concave block 43, the concave block 43 is fixedly connected to the lower surface of the bracket 2, the right surface of the concave block 43 is rotatably connected through a sleeve 47, the outer wall of the sleeve 47 is fixedly connected to a second de-icing wheel 42, and the second de-icing wheel 42 rotates on the inner wall of the concave block 43. The inner wall of the sleeve 47 is slidably connected to a connecting rod 46. The sleeve 47 and the connecting rod 46 can only slide left and right to ensure that the connecting rod 46 can rotate accordingly when the sleeve 47 rotates. The outer wall of the right end of the connecting rod 46 is rotatably connected to a frame 48. The provided frame 48 ensures the stability of the first de-icing wheel 41 when adjusting the position. The upper surface of the frame 48 is slidably connected to the right end of the lower surface of the bracket 2. The right surface of the connecting rod 46 is fixedly connected to a second bevel gear 45. The lower surface of the frame 48 is rotatably connected through a first de-icing wheel 41. The first de-icing wheel 41 is a prior art, a device specifically used for removing ice layers, commonly found in scenarios such as transmission lines, bridges, and roads that require snow and ice removal, and can be realized by those skilled in the art. Therefore, it will not be described in detail in this case. The upper surface of the first de-icing wheel 41 is fixedly connected to a first bevel gear 44. The outer wall of the first bevel gear 44 meshes with the outer wall of the second bevel gear 45. The first bevel gear 44 and the second bevel gear 45 are prior arts. When the second bevel gear 45 rotates, it will drive the first bevel gear 44 to rotate. A bidirectional threaded rod 52 is threaded through and connected to the rear end of the right surface of the frame 48.

[0033] Refer to Figure 2 - Figure 4 , the adjusting assembly includes a second motor 51, the second motor 51 is fixedly connected to the right surface of the bracket 2, the left surface of the second motor 51 is fixedly connected to a bidirectional threaded rod 52. The bidirectional threaded rod 52 is a prior art, which is a rod-shaped structure with two sets of threads with different helix directions on its outer wall. When rotating, the structures threaded on its outer wall will move linearly, and these structures will move in opposite or relative directions. At the same time, it has the characteristics of self-locking on the left and right to ensure the stability of the structural connection. The bidirectional threaded rod 52 is rotatably connected through the right surface of the bracket 2, and the outer wall of the right end of the bidirectional threaded rod 52 is fixedly connected to a driving wheel 54.

[0034] Refer to Figure 3 - Figure 4The hammering assembly also includes a fixed block 36, which is fixedly connected to the left side of the rear end of the upper surface of the bracket 2. The left surface of the fixed block 36 is rotatably connected with a rotating rod 37, and the left surface of the rotating rod 37 is fixedly connected to a connecting plate 35. The right surface of the rear end of the connecting plate 35 is fixedly connected to a cylindrical rod 31. A through groove 38 is provided on the left surface of the front end of the connecting plate 35, and a sliding rod 39 is slidably connected to the inner wall of the through groove 38. The rear surface of the sliding rod 39 is rotatably connected to the left surface of the rotating plate 34. The sliding rod 39 is specifically rotatably connected to the eccentric part of the left surface of the rotating plate 34. When the rotating plate 34 rotates, the sliding rod 39 will rotate at the eccentric part of the left surface of the rotating plate 34 with the center of the rotating plate 34 as the origin. At the same time, the inner wall of the through groove 38 of the sliding rod 39 slides back and forth repeatedly. Since the connecting plate 35 rotates with the center of the rotating rod 37, it will swing back and forth up and down driven by the sliding rod 39, so that the cylindrical rod 31 beats the wire body.

[0035] Reference Figure 1 - Figure 3 , there are multiple groups of bidirectional threaded rods 52, and the multiple groups of bidirectional threaded rods 52 are symmetrically arranged with the center line of the bracket 2 as the symmetry axis. The rear end of the driving wheel 54 is connected to the driven wheel 55 through the belt 53. The driven wheel 55 is fixedly connected to the outer wall of the right end of the multiple groups of bidirectional threaded rods 52. One end of the belt 53 contacts the inner wall of the driving wheel 54. Through the cooperation of the driving wheel 54, the belt 53 and the driven wheel 55, the multiple groups of bidirectional threaded rods 52 can be rotated synchronously to ensure the synchronization of the structural movement. The practicality is improved. The other end of the belt 53 contacts the inner wall of the driven wheel 55. There are multiple groups of belts 53, driving wheels 54 and driven wheels 55, and the multiple groups of driving wheels 54 and driven wheels 55 are connected through multiple groups of belts 53. The multiple groups of driving wheels 54 are fixedly connected to the outer wall of the right end of the sleeve 47, and the multiple groups of driven wheels 55 are fixedly connected to the outer wall of the round rod 33. One end of the multiple groups of belts 53 contacts the inner wall of the multiple groups of driven wheels 55, and the other end of the multiple groups of belts 53 contacts the outer wall of the multiple groups of driving wheels 54.

[0036] Working principle: When in use, the main body of the drone 1 can be controlled to fly to the wire where the ice needs to be cleared. Then, the second ice removing wheel 42 is brought into contact with the upper surface of the wire. At this time, the second motor 51 can be started. The second motor 51 drives the bidirectional threaded rod 52 to rotate. At this time, multiple groups of frames 48 threadedly connected to its outer wall will perform linear movement. The frames 48 drive the first ice removing wheel 41, the first bevel gear 44 and the second bevel gear 45 to move. The connecting rod 46 will also slide on the inner wall of the sleeve 47 accordingly to adjust the position, so that multiple groups of the first ice removing wheels 41 clamp the wire. At this time, the first motor 32 can be started. The first motor 32 drives multiple groups of driven wheels 55 to rotate. Multiple groups of driven wheels 55 drive the sleeve 47 to rotate through multiple groups of belts 53 and the driving wheel 54. The sleeve 47 drives the second ice removing wheel 42 to rotate. At the same time, the sleeve 47 drives the second bevel gear 45 to rotate through the connecting rod 46. The second bevel gear 45 drives the first bevel gear 44 to rotate. The first ice removing wheel 41 rotates synchronously with the first bevel gear 44 to clean the ice layer on the outer wall of the wire.

[0037] During the process of using the first ice removing wheel 41 and the second ice removing wheel 42 to clean the ice layer, the round rod 33 will also drive the rotating plate 34 to rotate. At this time, the sliding rod 39 rotates around the center of the rotating plate 34 at the eccentric position on the left surface of the rotating plate 34. At the same time, the inner wall of the through groove 38 of the sliding rod 39 slides back and forth repeatedly. Since the connecting plate 35 rotates around the center of the rotating rod 37, it will swing up and down reciprocally under the drive of the sliding rod 39, so that the cylindrical rod 31 pats the wire body, preventing some ice blocks from adhering to the wire body and not falling off, and improving the cleaning effect.

[0038] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
