Technical Field

[0001] The invention belongs to the technical field of power transmission line engineering, and in particular relates to a device for removing foreign matter from a power transmission line. Background Art

[0002] Foreign objects on transmission lines mainly include bird nests, kites, hydrogen balloons, wind-blown haystacks, sunshade nets covering greenhouses, billboards, ropes, branches, plastic sheets, tin foil strips, dust nets, etc. These foreign objects may pose a threat to the safe and stable operation of transmission lines, such as causing single-phase grounding of the ground wire, phase-to-phase short circuit and other tripping accidents. Therefore, it is very important to find and clean these foreign objects in time. Traditional methods usually rely on manual or simple mechanical devices for removal, such as using removal tools with insulated handles or relying on lifts on insulator strings for operation. However, these methods have certain limitations: on the one hand, manual removal methods are inefficient and unsafe, especially in complex terrain and high-altitude environments. On the other hand, existing mechanical devices have complex structures, are inconvenient to operate, and have poor adaptability to foreign objects, and cannot effectively remove foreign objects of different shapes and sizes, especially plastic sheets and dust nets that are extremely difficult to handle. Summary of the invention

[0004] To achieve the above objectives, the present invention provides a device for removing foreign objects from power transmission lines, wherein the foreign object removal component includes a cutting component and a clamping component, the cutting component is used to cut foreign objects, and the cutting component is located inside the upper cavity, the clamping component is used to clamp the cable and fix the foreign objects at the same time, and the clamping component is located inside the lower cavity.

[0005] In the above technical solution, further, the cutting assembly includes a motor fixedly connected to the inside of the covering shell through a mounting seat, the output end of the motor is fixedly connected to a No. 1 forward and reverse screw rod, the outer wall of the No. 1 forward and reverse screw rod is screwed with a No. 1 movable seat, the top of the No. 1 movable seat is fixedly connected with a cutting motor, the output end of the cutting motor is fixedly connected with a cutting tool through a rotating shaft, and the rotating shaft is inserted and slidably connected to the inside of the movable hole.

[0006] In the above technical scheme, further, the clamping assembly includes a No. 2 forward and reverse screw rod arranged in the lower cavity, a pulley group is arranged between the No. 2 forward and reverse screw rod and the No. 1 forward and reverse screw rod, a No. 2 movable seat is screwed on the outer wall of the No. 2 forward and reverse screw rod, and movable plates are inserted and slidably connected on both sides of the No. 2 movable seat, and an adaptation hole is opened on the outer wall of the movable plate, and protrusions are fixedly connected to the top of both sides of the No. 2 movable seat, and the protrusions are adapted to the adaptation holes, and the protrusions are inserted and slidably connected to the inside of the adaptation holes, and the bottom of the movable plate is fixedly connected with a uniformly distributed hanging plate, and the hanging plate is inserted and slidably connected to the inside of the sliding hole, and the bottom of the hanging plate is fixedly connected with a push plate, and the top side of the push plate is fixedly connected with uniformly distributed teeth, and one side of the push plate is fixedly connected with a wire clamp.

[0007] In the above technical solution, further, the two movable plates are provided with inclined sections on one side close to each other, and the shapes of the two ends of the second movable seat, the protruding pieces and the matching holes are all matched with the inclined sections.

[0008] In the above technical scheme, further, the outer walls of the No. 1 forward and reverse screw rod and the No. 2 forward and reverse screw rod are both provided with a partition assembly, and the partition assembly includes a driving shaft and a driven shaft, the driving shaft is a section close to the pulley group, and the driven shaft is a section away from the pulley group, the end of the driving shaft close to the driven shaft is fixedly connected with a cam, the end of the driven shaft close to the driving shaft is fixedly connected with a fixing plate, a movable column is inserted into and slidably connected to the inside of the fixing plate, a limiting plate is fixedly connected to the middle part of the outer wall of the movable column, a reset spring is fixedly connected between the limiting plate and the inner side of the fixing plate, and the reset spring is sleeved on the outside of the movable column.

[0009] In the above technical solution, further, the cam arranged on the first forward and reverse screw rod and the cam arranged on the second forward and reverse screw rod are opposite to each other.

[0011] Compared with the prior art, the present invention has the following beneficial effects: Through the connection of the pulley group, the No. 2 forward and reverse screw rods are synchronously rotated and drive the No. 2 moving seat to move. Because the movable plate is an inclined surface and is connected through the convex piece, during the movement of the No. 2 moving seat, its convex piece is always inside the adapter hole and its position remains unchanged. Therefore, the movable plate can be pulled to move during reciprocating motion. Because the bottom of the movable plate is fixed with a wire clamp through the hanging plate and the push plate, the wire clamps can clamp the cables when they face each other to ensure the stability of the application during operation. Because the gears are meshed with the teeth, the push plate will drive the gears to rotate when it is pushed, and synchronously drive the C-shaped column tube to rotate. During the rotation process, the C-shaped column tube contacts the floating plastic sheet and the dust screen and pushes up to the opposite side. When the wire clamp completes the fixation of the cable, the C-shaped column tube also pushes the foreign matter upward. Through such a design, it is convenient for the cutting assembly to cut the foreign matter, and it is not limited to the floating direction of the foreign matter, making the application practical. When the motor drives the No. 1 forward and reverse screw rods and the No. 2 forward and reverse screw rods to rotate, the two active shafts are constantly rotating, and the cam of one of the active shafts collides with the movable column, so that the active shaft synchronously drives the driven shaft to rotate, and the cam of the other active shaft continuously lifts the movable column. At this time, the other driven shaft will not rotate. Through this design, during use, by controlling the forward and reverse rotation of the motor, the clamping assembly will first clamp the cable. At this time, the cutting assembly will not move and will not cut foreign objects that have not been lifted up. Then, the steering is controlled, the cutting assembly moves, and the foreign objects are cut. The clamping assembly will not be affected during the process. The two components are driven by the same source, but can independently complete their respective functions. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] In the above setting, foreign objects are removed by setting a foreign object removal component, and a cargo-carrying drone 1 is set to drive the foreign object removal component to perform high-altitude operations. Through such a design, there is no need for maintenance personnel to perform high-altitude operations. The present application has a reasonable structure and high linkage, so that maintenance personnel do not need to perform high-altitude operations, optimizes the maintenance process, reduces maintenance expenses, and protects the personal safety of maintenance personnel, making the removal of foreign objects easier.

[0016] The foreign matter removal group includes a cutting component, which is used to cut foreign matter and is located inside the upper cavity. The cutting component includes a motor 5 fixedly connected to the inside of the covering shell 3 through a mounting seat, and the output end of the motor 5 is fixedly connected to a No. 1 forward and reverse screw rod 7, and the outer wall of the No. 1 forward and reverse screw rod 7 is screwed with a No. 1 movable seat 26, and the top of the No. 1 movable seat 26 is fixedly connected with a cutting motor 9, and the output end of the cutting motor 9 is fixedly connected with a cutting tool 10 through a rotating shaft, and the rotating shaft is inserted and slidably connected to the inside of the movable hole 4.

[0017] In the above setting, the cutting motor 9 is started to drive the cutting tool 10 to rotate to cut the foreign matter, and the motor 5 drives the No. 1 forward and reverse screw rod 7 to rotate, so that the No. 1 moving seat 26 drives the cutting motor 9 and the cutting tool 10 to move back and forth to cut the dust net and plastic cloth.

[0018] The foreign body removal group includes a clamping component, which is used to clamp the cable and fix the foreign body at the same time. The clamping component is located inside the lower cavity. The clamping component includes a No. 2 forward and reverse screw rod 8 arranged in the lower cavity. A pulley group 6 is arranged between the No. 2 forward and reverse screw rod 8 and the No. 1 forward and reverse screw rod 7. The outer wall of the No. 2 forward and reverse screw rod 8 is screwed with a No. 2 movable seat 15. Both sides of the No. 2 movable seat 15 are inserted and slidably connected with movable plates 16. The outer wall of the movable plate 16 is provided with an adapter hole 17. The tops of both sides of the No. 2 movable seat 15 are fixedly connected with protrusions 18, and the protrusions 18 and the adapter holes 1 7 is adapted, and the protruding piece 18 is inserted and slidably connected to the inside of the adapting hole 17, the bottom of the movable plate 16 is fixedly connected with the evenly distributed hanging plates 19, and the hanging plate 19 is inserted and slidably connected to the inside of the sliding hole, the bottom of the hanging plate 19 is fixedly connected with the push plate 20, the top side of the push plate 20 is fixedly connected with the evenly distributed teeth 23, one side of the push plate 20 is fixedly connected with the wire clamp 21, the two movable plates 16 are provided with inclined sections on the sides close to each other, and the shapes of the two ends of the No. 2 movable seat 15, the protruding piece 18 and the adapting hole 17 are adapted to the inclined sections.

[0019] In the above setting, through the connection of the pulley group 6, the No. 2 forward and reverse screw rods 8 are rotated synchronously and drive the No. 2 movable seat 15 to move. Because the movable plate 16 is an inclined surface and because of the connection through the protrusion 18, during the movement of the No. 2 movable seat 15, the protrusion 18 is always inside the adapter hole 17 and its position remains unchanged. Therefore, the movable plate 16 can be pulled to move during reciprocating motion. Because the bottom of the movable plate 16 is fixed with a wire clamp 21 through the hanging plate 19 and the push plate 20, the wire clamp 21 can clamp the cable when facing each other to ensure the stability of the application during operation.

[0020] The bottom of the covering shell 3 is fixedly connected to a connecting shaft 25 via a fixing block, the end of the connecting shaft 25 is fixedly connected to a C-shaped column tube 22 , the end of the connecting shaft 25 is fixedly connected to a gear 24 , and the gear 24 is meshed with the teeth 23 .

[0021] In the above setting, it should be noted that the C-shaped column tubes on both sides do not correspond, and the spacing on one side is larger than that on the other side. Because the gear 24 is meshed with the tooth 23, the push plate 20 will drive the gear 24 to rotate while being pushed, and synchronously drive the C-shaped column tube 22 to rotate. During the rotation process, the C-shaped column tube 22 contacts the floating plastic sheet and the dust net and pushes up to the opposite side. When the wire clamp 21 completes the fixation of the cable, the C-shaped column tube 22 also pushes the foreign matter upward. Through such a design, it is convenient for the cutting assembly to cut the foreign matter, and it is not limited to the floating direction of the foreign matter, making the present application practical.

[0022] The outer walls of the No. 1 forward and reverse screw rod 7 and the No. 2 forward and reverse screw rod 8 are both provided with partition assemblies, and the partition assemblies include a driving shaft and a driven shaft, the driving shaft is a section close to the pulley group 6, and the driven shaft is a section away from the pulley group 6, the end of the driving shaft close to the driven shaft is fixedly connected with a cam 11, and the end of the driven shaft close to the driving shaft is fixedly connected with a fixed plate 12, and a movable column 14 is inserted and slidably connected inside the fixed plate 12, and a limiting plate is fixedly connected to the middle part of the outer wall of the movable column 14, and a reset spring 13 is fixedly connected between the limiting plate and the inner side of the fixed plate 12, and the reset spring 13 is sleeved on the outside of the movable column 14, and the cam 11 arranged on the No. 1 forward and reverse screw rod 7 and the cam 11 arranged on the No. 2 forward and reverse screw rod 8 are opposite to each other.

[0023] In the above setting, when the motor 5 drives the No. 1 forward and reverse screw rod 7 and the No. 2 forward and reverse screw rod 8 to rotate, the two active shafts are always rotating, and the cam 11 of one of the active shafts collides with the movable column 14, so that the active shaft synchronously drives the driven shaft to rotate, and the cam 11 of the other active shaft continuously lifts the movable column 14. At this time, the other driven shaft will not rotate. Through this design, during use, by controlling the forward and reverse rotation of the motor 5, the clamping assembly first clamps the cable. At this time, the cutting assembly will not move and will not cut the foreign objects that have not been lifted up. Then the steering is controlled, the cutting assembly moves, and the foreign objects are cut. The clamping assembly will not be affected during the process. The two components are driven by a driving source, but can independently complete their respective functions.

[0024] Working principle: By setting a foreign object removal component to remove foreign objects, and by setting a cargo-carrying drone 1 to drive the foreign object removal component to perform high-altitude operations, through such a design, maintenance personnel do not need to perform high-altitude operations. The application has a reasonable structure and high linkage, so that maintenance personnel do not need to perform high-altitude operations, optimize the maintenance process, reduce maintenance expenses, and protect the personal safety of maintenance personnel, making it easier to remove foreign objects; Through the connection of the pulley group 6, the No. 2 forward and reverse screw rods 8 are synchronously rotated and drive the No. 2 moving seat 15 to move. Because the movable plate 16 is an inclined surface and is connected through the protruding piece 18, during the movement of the No. 2 moving seat 15, the protruding piece 18 is always inside the adapter hole 17 and its position remains unchanged. Therefore, the movable plate 16 can be pulled to move when it makes a reciprocating motion. Because the bottom of the movable plate 16 is fixed with a wire clamp 21 through the hanging plate 19 and the push plate 20, the wire clamp 21 can be connected to clamp the cable to ensure the stability of the application during operation. Because the gear 24 is meshed with the teeth 23, the push plate 20 is pushed and the gear 24 is driven to rotate, which in turn drives the C-shaped column tube 22 to rotate. During the rotation, the C-shaped column tube 22 contacts the floating plastic sheet and the dust screen and pushes up to the opposite side. When the wire clamp 21 completes the fixing of the cable, the C-shaped column tube 22 also pushes the foreign matter upward. With such a design, it is convenient for the cutting assembly to cut the foreign matter, and it is not limited to the floating direction of the foreign matter, making the present application practical. When the motor 5 drives the No. 1 forward and reverse screw rod 7 and the No. 2 forward and reverse screw rod 8 to rotate, the two active shafts are rotating all the time, and the cam 11 of one of the active shafts collides with the movable column 14, so that the active shaft synchronously drives the driven shaft to rotate, and the cam 11 of the other active shaft continuously lifts the movable column 14, and the other driven shaft will not rotate at this time. Through this design, during use, by controlling the forward and reverse rotation of the motor 5, the clamping assembly will first clamp the cable, and the cutting assembly will not move at this time, and will not cut the foreign matter that has not been lifted up. Then the steering is controlled, the cutting assembly moves, and the foreign matter is cut. The clamping assembly will not be affected during the process, and the two assemblies are driven by the same source, but can independently complete their respective functions.
