Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of power supply lines, and in particular to a protective device for overhead lines. Background Art
[0002] Ensuring the normal operation of transmission and distribution lines is crucial in power systems. Failures in overhead lines can cause power outages, short circuits, and other electrical failures, resulting in significant losses for both power producers and consumers. However, one of the primary causes of this problem is birds nesting on overhead lines. Birds frequently rest and nest on these lines, making them susceptible to damage from feathers and nesting branches, leading to failures.
[0003] In addition, when there is strong wind, the conductors of the overhead lines tend to swing with the wind, and the existing overhead lines cannot slow down the swing amplitude of the conductors, resulting in excessive swing amplitude of the conductors, which can easily cause the connections to fall off, causing faults such as breakage.
[0004] Therefore, we make improvements to this problem and propose a protective device for overhead lines. Summary of the Invention
[0005] The technical problem to be solved by the present invention is that birds roosting can cause power outages, short circuits and other power failures in overhead lines. The conductors of overhead lines are easily swung by the wind, and the swing amplitude is large, which can easily cause the conductors to fall off, resulting in faults such as breakage.
[0006] In order to achieve the above-mentioned purpose of the invention, the present invention provides a protective device for overhead lines, including a protective tube, which is sleeved on the outside of the line, and mounting sleeves are sleeved on both ends of the protective tube. The mounting sleeve includes a rotating ring, and two rollers are symmetrically installed on the middle part of the rotating ring. The two rollers are rollingly clamped on the outside of the barrel of the protective tube. Four connecting shafts are equidistantly installed on the circumferential surface of the rotating ring, and a rotating frame is connected to the connecting shaft. A cleaning brush is connected to the inner side of the rotating ring, and the cleaning brush is wrapped and installed on the outside of the protective tube. One end of the outer side of the protective tube is connected to a connecting buckle, and the connecting buckle is sleeved on the insulator at the end of the line.
[0007] As a further solution of the present invention, the protective tube includes two symmetrical sections of telescopic net tubes, and the outer ends of the two sections of the telescopic net tubes are installed with connecting tubes. The connection between the two sections of the telescopic net tubes is provided with a first locking buckle, and the first locking buckle is locked by a bolt.
[0008] As a further solution of the present invention, the cleaning brush includes two sections of spiral strips, the outer ends of the two sections of the spiral strips are installed with fixed rods, the two sections of the spiral strips are provided with brush strips, the fixed rods are fixed on the rotating ring, and the connection between the two sections of the spiral strips is provided with a second locking buckle, which is locked by a bolt.
[0009] As a further solution of the present invention, the rotating frame includes a bent pipe, both ends of the bent pipe are equipped with clips, the clips are sleeved and fixed on the connecting shaft, and a bell is sleeved on the outer side of the bent pipe.
[0010] As a further solution of the present invention, the bell includes an independent first metal plate and a second metal plate, the first metal plate and the second metal plate are both funnel-shaped, and the outer sides of the first metal plate and the second metal plate are connected to several metal sheets.
[0011] As a further solution of the present invention, the number of the mounting sleeves is four, and the sides of the four mounting sleeves are respectively connected to four connecting rods, the four connecting rods are cross-distributed in an X shape, and the bottom ends of the four connecting rods are connected to the same connecting block, and a telescopic rod is connected between two adjacent connecting rods.
[0012] As a further solution of the present invention, the connecting buckle includes several connecting ropes, several of which are connected to the outer side of the telescopic net tube, the outer side of the connecting rope is connected to a third locking buckle, and a raised ring is provided in the middle of the third locking buckle.
[0013] As a further solution of the present invention, the bent pipe is a round rod bent in a W shape along the circumferential surface of the mounting sleeve.
[0014] As a further solution of the present invention, the first metal plate and the second metal plate slide back and forth toward the two ends of the curved pipe respectively under the force of gravity.
[0015] The present invention provides a protective device for overhead lines, which has the following beneficial effects: 1. By clamping mounting sleeves at both ends of the outer side of the protective tube, and connecting a cleaning brush and a rotating frame in the middle of the mounting sleeves at both ends, when a bird stands on the rotating frame, the rotating frame is forced to drive the mounting sleeve to rotate, so that the forced rotating frame rotates to the bottom of the protective tube to prevent the bird from standing firmly. During the rotation, the first metal plate and the second metal plate connected to the bent pipe slide along the bent pipe toward the middle of the bent pipe, and the sound of the collision between the first metal plate and the second metal plate drives away the birds. At the same time, the rotating mounting sleeve drives the cleaning brush to wipe the surface of the protective tube to remove dust and debris on the protective tube, thereby promoting the safety of overhead line power transmission and ensuring that the power supply is no longer affected by birds.
[0016] 2. By setting up a protective tube to wrap the wires in the line, the protective tube increases the protection strength of the outside of the wires, protects the damaged wires, prevents the wires from breaking and sagging, and ensures the safety of the line ground. In addition, since the telescopic network tube pulls the wires, it also prevents the middle part of the wires from sinking and swinging due to gravity, and prevents the wires from falling off due to excessive swinging in the wind.
[0017] 3. By setting the connecting block and the connecting rod, the connecting rod is connected to the installation sleeve, so that multiple groups of wires can be protected and supported by multiple installation sleeves. At the same time, the connecting rod and the telescopic rod connect the multiple groups of wires into a whole, so that the distance and width between the multiple groups of wires remain stable, and the multiple wires are placed to prevent entanglement.

[0021] The following embodiments of the present invention are described in further detail in conjunction with the accompanying drawings and examples. The following embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.
[0022] like Figures 1-10 As shown, this embodiment proposes a protective device for overhead lines, including a protective tube 5, which is sleeved on the outside of the line, and mounting sleeves 4 are sleeved on both ends of the protective tube 5. The mounting sleeve 4 includes a rotating ring 41, and two rollers 42 are symmetrically installed in the middle of the rotating ring 41. The two rollers 42 are rollingly clamped on the outside of the tube body of the protective tube 5. Four connecting shafts 43 are equidistantly installed on the circumferential surface of the rotating ring 41, and a rotating frame 7 is connected to the connecting shaft 43. A cleaning brush 6 is connected to the inner side of the rotating ring 41, and the cleaning brush 6 is wound and installed on the outside of the protective tube 5. One end of the outer side of the protective tube 5 is connected to a connecting buckle 8, and the connecting buckle 8 is sleeved on the insulator at the end of the line.
[0023] The protective tube 5 includes two symmetrical sections of telescopic net tubes 51, and the outer ends of the two sections of telescopic net tubes 51 are both installed with connecting tubes 52. The connection between the two sections of telescopic net tubes 51 is provided with a first locking buckle 53, which is locked by bolts. The two sections of telescopic net tubes 51 are connected by the first locking buckle 53 and the bolts, which is convenient for the protective tube 5 to wrap and protect the wires. At the same time, when the wires need to be repaired, the telescopic net tube 51 can be squeezed and deformed to both sides by disassembling the first locking buckle 53, so that the faulty part of the wire is exposed, which is convenient for the repair and replacement of the wires, and the two sections of telescopic net tubes 51 are sutured and fixed again after repair.
[0024] The cleaning brush 6 includes two sections of spiral strips 61, and the outer ends of the two sections of spiral strips 61 are installed with fixed rods 63. Brush strips 62 are provided on the two sections of spiral strips 61. The fixed rods 63 are fixed on the rotating ring 41. The connection between the two sections of spiral strips 61 is provided with a second lock buckle 64, and the second lock buckle 64 is locked by a bolt. The tightness of the two sections of spiral strips 61 and the two sections of telescopic network tubes 51 are kept synchronized, so that the wires are protected or exposed, which is conducive to the maintenance of the wires.
[0025] When the bracket 71 is in the closed position, the locking yoke 72 is locked and the locking yoke 73 is locked, so that the locking yoke 72 can be locked in the closed position.
[0026] The bell 73 includes an independent first metal plate 731 and a second metal plate 732. The first metal plate 731 and the second metal plate 732 are both funnel-shaped, and the outer sides of the first metal plate 731 and the second metal plate 732 are connected to several metal sheets 733. The first metal plate 731 and the second metal plate 732 slide toward the bottom along the curvature of the curved pipe 71 separately, and make noise when colliding to drive away birds. The surface of the metal sheet 733 is reflective and rotates due to the airflow, so that the reflection drives away the birds.
[0027] There are four mounting sleeves 4, and four connecting rods 2 are connected to the sides of the four mounting sleeves 4 respectively. The four connecting rods 2 are cross-distributed in an X shape, and the bottom ends of the four connecting rods 2 are connected to the same connecting block 1. A telescopic rod 3 is connected between two adjacent connecting rods 2. The connecting block 1, the connecting rod 2 and the telescopic rod 3 connect the mounting sleeves 4 on the outside of multiple groups of wires to fix the width distance of multiple groups of wires and avoid entanglement and knotting of multiple wires.
[0028] The connecting buckle 8 includes several connecting ropes 81, and the several connecting ropes 81 are connected to the outer side of the telescopic mesh tube 51. The outer side of the connecting rope 81 is connected to a third locking buckle 82. The middle part of the third locking buckle 82 is provided with a raised ring 83. The third locking buckle 82 is connected to the protective tube 5 through the connecting rope 81. The protective tube 5 is fixed to the wire between the insulators at both ends of the wire through the fixing of the connecting buckle 8 to the insulator, thereby ensuring the stability of the protective tube 5 when connected.
[0029] The curved pipe 71 is a round rod bent in a W shape along the circumferential surface of the mounting sleeve 4. The curvature of the curved pipe 71 causes the center of gravity of the curved pipe 71 to shift. When a bird stands on the curved pipe 71, a lever principle is generated to rotate the mounting sleeve 4. The rotating rotating frame 7 will drive away the birds, and it is also convenient for the bell 73 to slide up and down, so that the bell 73 can play the role of driving away birds.
[0030] The first metal plate 731 and the second metal plate 732 slide back and forth toward the two ends of the curved pipe 71 under the force of gravity. The first metal plate 731 and the second metal plate 732 collide at the lowest point of the curved portion of the curved pipe 71, and the noise generated by the collision drives away the birds.
[0031] When the wire is in the air, the wires are pulled out of the air filter 5 and the air filter 6 is pulled out of the air filter 5. When the wire is in the air, the wires are pulled out of the air filter 5 and the air filter 6 is pulled out of the air filter 5. When the wire is in the air, the wires are pulled out of the air filter 5 and the air filter 6 is pulled out of the air filter 5. When the wire is in the air, the wires are pulled out of the air filter 5 and the air filter 6 is pulled out of the air filter 5. The mounting sleeve 4 drives the cleaning brush 6 to wipe the surface of the protective tube 5, removing dust and debris on the protective tube 5, promoting the safety of overhead line power transmission, and ensuring that the power supply is no longer affected by birds; a protective tube 5 is set to wrap the wires in the line so that the protective tube 5 increases the protection strength of the outside of the wires, and protects the damaged wires in response to the damage of the wires, prevents the wires from breaking and sagging, and ensures the safety of the line ground. Moreover, since the telescopic network tube 51 pulls the wires, it also prevents the middle part of the wires from sinking and swinging due to gravity, and prevents the wires from falling off due to excessive swinging with the wind; a connecting block 1 and a connecting rod 2 are set, and the connecting rod 2 is connected to the mounting sleeve 4, so that multiple groups of wires are protected and supported by multiple mounting sleeves 4, and at the same time, the connecting rod 2 and the telescopic rod 3 connect the multiple groups of wires into a whole, so that the distance width between the multiple groups of wires remains stable, and entanglement between multiple wires is prevented.
