Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of unmanned aerial vehicles, in particular to an overhead cable live installation spacer auxiliary unmanned aerial vehicle. BACKGROUND

[0002] With the increase of the mass per unit length of the power line, the mass of the hardware and the diameter of the conductor, the probability of line galloping increases. Common anti-galloping devices include turbulence anti-galloping devices, detuned pendulums, anti-vibration hammers, spacers, etc. Among them, phase-to-phase spacers, spacers on single-phase bundled conductors, and phase-to-ground spacers all have the effect of suppressing conductor galloping. Through corresponding engineering practice, phase-to-phase spacers have obvious effect on anti-galloping and galloping suppression, and are the most widely used anti-galloping device at present. Spacers are configured in compact lines to play the role of insulating line phase-to-phase and supporting connection. As a commonly used device for preventing galloping, phase-to-phase spacers are not only suitable for single conductors, but also can be used in bundled conductors. They have good insulation capacity and mechanical strength, can effectively support and constrain different phase conductors to achieve the purpose of anti-galloping. Therefore, the conventional disposal method of power companies is to install phase-to-phase spacers to reduce the occurrence of the above faults, and this method has been proven to be simple, effective and reliable through operation verification over the past few decades.

[0003] 10KV lines have problems such as thin conductors that cannot be installed on the line, unfavorable terrain that cannot be erected, and live working hoists that cannot reach, etc. The cost of power-off installation is too high and the cost of adding poles and changing routes is even higher. Therefore, it is necessary to develop a more scientific and applicable safe installation method for installing phase-to-phase spacers on 10kV distribution lines to ensure that the line short-circuit trip frequency can be significantly reduced and the power supply reliability can be ensured.

[0004] Anti-galloping of transmission and distribution lines is a long-term problem, especially for transmission and distribution lines crossing large rivers and large rivers. The anti-galloping of phase-to-phase conductors is even more urgent. The conventional construction method cannot reach the designated installation position, especially the environment under the installation position is very bad, which brings great difficulty to the on-site operation.

DETAILED DESCRIPTION

[0046] The application will be further described below in conjunction with the drawings and examples. It should be understood that the specific examples described herein are intended to explain the application and are not intended to limit the application, i.e., the described examples are only a part of the examples of the application, rather than all the examples.

[0047] The specific embodiments of the aerial cable live-line installation spacer auxiliary unmanned aerial vehicle provided by the application are as follows:

[0048] Please refer to the accompanying Figures 1-13 , the aerial cable live-line installation spacer auxiliary unmanned aerial vehicle, comprising an unmanned aerial vehicle body 7, a polygonal cylinder frame 1, a chain belt frame 2, a plurality of mounting pieces 3, a plurality of main lifting ropes 5 and a winding and releasing assembly 6.

[0049] The polygonal cylinder frame 1 is located below the unmanned aerial vehicle body 7 and is arranged horizontally; the chain belt frame 2 has a structure of a plurality of sections hingedly connected end to end, and the chain belt frame 2 in the initial state is wrapped around the outer side of the lower part of the polygonal cylinder frame 1 in a U shape; the plurality of mounting pieces 3 are connected at the hinged portions of the chain belt frame 2 and are used for mounting and releasing the spacer body 4; the plurality of main lifting ropes 5 are respectively connected to the upper sides of the two ends of the chain belt frame 2; and the winding and releasing assembly 6 is installed on the lower side of the unmanned aerial vehicle body 7, is connected to the upper ends of the main lifting ropes 5 and is used for winding and releasing the main lifting ropes 5.

[0050] As Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the lower side of the UAV body 7 is connected to the top plate 9 by bolts, the top plate 9 is provided with through holes at the four corners, and the lower side of the UAV body 7 is provided with threaded holes for threaded connection with the bolts. The top plate 9 is connected to a column at the middle lower side, the lower end of the column is connected to a support plate 10, and the support plate 10 is connected to rectangular frame-shaped support legs 11 at both ends and both sides. In the landing state, the support legs 11 are in contact with the ground to support the UAV body 7. The winding and unwinding assembly 6 of the main hoisting rope 5 is arranged on the support plate 10. Since the UAV body 7 is connected to the chain belt frame 2 through the main hoisting rope 5, the chain belt frame 2 and the polygonal cylinder frame 1 do not affect the landing of the support legs 11.

[0051] The winding and unwinding assembly 6 includes two groups of winding reels 12 rotatably installed at the lower side of the UAV body 7. In this embodiment, the winding reels 12 are rotatably installed at the lower side of the support plate 10, each group has two winding reels 12, and there are a total of four winding reels 12. The two winding reels 12 in the same group are connected by a reel shaft 13 for synchronous and same-direction rotation. The reel shafts 13 of the two groups of winding reels 12 are arranged in parallel and located at the lower side of the two ends of the support plate 10.

[0052] The two ends of the chain belt frame 2 are connected to two main hoisting ropes 5, the middle portions of the two main hoisting ropes 5 at the same end of the chain belt frame 2 are connected to a plurality of parallel cross bars, and the lower ends of the two main hoisting ropes 5 at the same end of the chain belt frame 2 are connected to a support rod which is hingedly connected to the end of the chain belt frame 2.

[0053] The upper ends of the two main hoisting ropes 5 at the same end of the chain belt frame 2 are wound around the outside of the two winding reels 12 in the same group, so that the two groups of winding reels 12 respectively wind and unwind the main hoisting ropes 5 at the two ends of the chain belt frame 2.

[0054] A motor 14 is installed at the lower side of the UAV body 7. In this embodiment, the motor 14 is installed at the middle portion of the support plate 10, the output shaft of the motor 14 extends to the lower side of the middle portion of the support plate 10, the lower side of the middle portion of the support plate 10 is provided with a shaft seat for supporting the rotation of the output shaft of the motor 14, and the lower sides of the two ends of the support plate 10 are provided with shaft seats for supporting the rotation of the reel shafts 13.

[0055] The output shaft of the motor 14 drives the rotation of the two groups of winding reels 12 through two groups of belt drive mechanisms 15. The belt drive mechanism 15 includes an annular transmission belt and a belt pulley located at the inner side of both ends of the transmission belt. The output shaft of the motor 14 drives the rotation of the two groups of winding reels 12 through the belt drive mechanism 15. Although the two groups of winding reels 12 rotate synchronously, one group of winding reels 12 winds the main hoisting rope 5 while the other group of winding reels 12 releases the main hoisting rope 5, so that the vertical total span of the main hoisting rope 5 and the chain belt frame 2 remains unchanged. In this embodiment, the transmission belt is a synchronous belt, and the belt pulley is a synchronous belt pulley, which ensures the stability of the transmission ratio and avoids slipping.

[0056] The structure of the chain belt frame 2 is similar to that of a conventional chain. In this embodiment, the chain structure is improved, specifically, the length of the enlarged chain plate is increased, and the length of the chain shaft is increased, and the length of the chain shaft is greater than one-half of the length of the spacer rod body 4. Figure 6 ,Figure 7 、 Figure 8 and Figure 9 In this embodiment, the chain rack 2 includes a plurality of hinge shafts 16, and each of the hinge shafts 16 is hingedly connected between the ends of adjacent plate strip groups 17. Each plate strip group 17 includes two parallel plate strips. The plate strip groups 17 at the same end of the chain rack 2 are axially staggered, and the plate strip groups 17 adjacent to the same plate strip group 17 are axially corresponding. That is, the axial positions of the two plate strip groups 17 separated by one plate strip group 17 are corresponding. The support rod at the lower end of the main hoisting rope 5 is hingedly connected to the hinge shaft 16 at the end of the chain rack 2.

[0057] The hinge shaft 16 is provided with a plurality of annular protrusions at both ends, which are used to limit the positions of the plate strips of the plate strip group 17 and avoid the axial positions of the plate strips from being staggered. The plate strips are each provided with a through hole for the hinge shaft 16 to pass through, so that the plate strips and the hinge shaft 16 can rotate relative to each other. The length of the plate strip group 17 matches the width of the side of the polygonal cylinder frame 1, and the axial length of the polygonal cylinder frame 1 matches the length of the hinge shaft 16.

[0058] The polygonal cylinder frame 1 in this embodiment is provided with a polygonal frame 20 at each end. The polygonal frame 20 is an octagonal frame, and the number of polygonal frames 20 is two. The polygonal cylinder frame 1 further includes a rotating shaft 19 passing through the center of the polygonal frame 20, and a plurality of radial rods are connected between the outer side of the end of the rotating shaft 19 and the inner side of the polygonal frame 20.

[0059] The unmanned aerial vehicle body 7 is connected with a secondary hoisting rope 8 at the lower side. The secondary hoisting rope 8 is connected with a cylindrical hanging seat 18 at the lower end. The rotating shaft 19 at the center of the polygonal cylinder frame 1 rotates through the hanging seat 18, and the inner side of the hanging seat 18 is provided with a bearing supporting the rotating shaft 19. The function of the secondary hoisting rope 8 is to avoid the polygonal cylinder frame 1 from separating and falling off the chain rack 2, thereby avoiding unnecessary safety risks. The length of the secondary hoisting rope 8 should be such that the gravity of the polygonal cylinder frame 1 is pressed on the inner side of the lower part of the chain rack 2, and the polygonal cylinder frame 1 acts as a counterweight and rotates with the movement of the chain rack 2. The secondary hoisting rope 8 cannot be too loose, that is, it cannot be bent in the initial state, so as to reduce the shaking of the secondary hoisting rope 8, and at the same time, when the polygonal cylinder frame 1 rotates, it can also limit the rotation of the hanging seat 18.

[0060] The plate strip group 17 corresponds to the frame of the polygonal frame 20. The outer side of each frame of the polygonal frame 20 is provided with two parallel limiting plates 21 extending into the plate strips of the plate strip group 17. That is, the outer side of each polygonal frame 20 is provided with two rings of limiting plates 21. In this embodiment, the two limiting plates 21 on the same frame of the polygonal frame 20 can simultaneously extend into the plate strips of the plate strip group 17 at most only one limiting plate 21, because one plate strip group 17 is connected between the same ends of two adjacent hinge shafts 16.

[0061] The plurality of limiting plates 21 outside the polygonal frame 20 can cooperate with the slat groups 17 on the chain belt frame 2 to achieve limiting, avoid separation of the two, and then when the chain belt frame 2 moves by winding and unwinding the main hoisting rope 5, the polygonal barrel frame 1 can be stably pressed inside the chain belt frame 2.

[0062] The mounting member 3 is connected to the hinge shaft 16. The mounting member 3 includes a U-shaped plate 22 connected to the hinge shaft 16, and the U-shaped plate 22 is provided with an electric telescopic rod 23 at the end. Two electric telescopic rods 23 are installed on each U-shaped plate 22, and the two electric telescopic rods 23 are oppositely arranged at the two ends of the U-shaped plate 22, i.e. the telescopic ends of the two electric telescopic rods 23 are opposite.

[0063] The polygonal barrel frame 1 in the embodiment adopts an octagonal barrel frame, and the chain belt frame 2 has eight slat groups 17 at the same end. In the initial state, four slat groups 17 are attached to the outside of the end of the octagonal barrel frame, and the remaining four slat groups 17 have two groups at each end in a vertical state.

[0064] In the embodiment, the number of hinge shafts 16 of the chain belt frame 2 is nine, and the mounting member 3 is installed outside the five hinge shafts 16 in the middle. The four hinge shafts 16 at both ends each have two hinge shafts 16 outside which are not installed with the mounting member 3. Two mounting members 3 are symmetrically installed on each hinge shaft 16 on which the mounting member 3 is installed, and the two mounting members 3 act on the two ends of the spacer rod body 4 to realize the mounting of the five spacer rod bodies 4. The embodiment can simultaneously carry five spacer rod bodies 4 to ascend, install the spacer rod bodies 4 one by one, reduce the flight frequency between the ground and the air, improve the work efficiency, and simplify the installation process.

[0065] The chain belt frame 2 without the mounting member 3 on the four hinge shafts 16 at both ends can be attached to the outside of the polygonal barrel frame 1 during movement, ensuring the stability of the movement of the chain belt frame 2 and the rotation of the polygonal barrel frame 1, and not playing a role in mounting the spacer rod body 4.

[0066] The hinge shaft 16 corresponds to the corner of the polygonal barrel frame 1; before the spacer rod body 4 is released and installed, different hinge shafts 16 of the chain belt frame 2 are located at the lowermost end, different pointed ends of the polygonal barrel frame 1 correspond downward, and the spacer rod body 4 carried by the hinge shaft 16 at the lowermost end is located at the lowermost end and contacts the wire for installation; then the installation of the spacer rod body 4 is completed one by one.

[0067] As Figure 10 , Figure 11 , Figure 12 and Figure 13As shown, the spacer rod body 4 is provided with a reverse U-shaped end seat 39 at both ends, and a clamping structure for clamping the wire is arranged in the end seat 39. The lower side of the spacer rod body 4 near the middle of both ends is provided with an expansion frame 32, which is approximately U-shaped and connected to the spacer rod body 4 at both ends. The expansion frame 32 near the end seat 39 is provided as an inclined portion, and the end of the inclined portion is connected to the end of the reverse U-shaped opening of the end seat 39 near the middle of the rod body. When the spacer rod body 4 is lowered, the inclined portion makes it easier for the wire to enter the end seat 39 and be clamped, reducing the difficulty of installation.

[0068] The spacer rod body 4 is provided with a hole plate 24 corresponding to the electric telescopic rod 23. In this embodiment, the expansion frame 32 is provided with two opposite hole plates 24 corresponding to the two electric telescopic rods 23 of the mounting member 3, which realize the mounting of the spacer rod body 4. The two hole plates 24 are placed inside the port of the U-shaped plate 22 of the mounting member 3, and the hole plate 24 corresponds to the electric telescopic rod 23. The telescopic ends of the electric telescopic rods 23 at both ends of the mounting member 3 extend into the hole plate 24, realizing the mounting of the spacer rod body 4 by the mounting member 3. The two mounting members 3 at both ends of the hinge shaft 16 mount the spacer rod body 4 at both ends, ensuring the balance of the spacer rod body 4 when mounted.

[0069] The spacer rod body 4 is provided with a fixed clamping block 25 and a movable clamping block 26 for clamping the wire at both ends. The fixed clamping block 25 and the movable clamping block 26 are both located at the end seat 39. The movable clamping block 26 is connected with two guide rods 27, which slide through the side wall near the middle of the spacer rod body 4. The inner end of the two guide rods 27 is connected with an end plate 28. The movable clamping block 26 is connected with a tension spring 29 that moves the movable clamping block 26 towards the fixed clamping block 25. The tension spring 29 is located outside the guide rod 27, and the ends of the tension spring 29 are connected with the end plate 28 and the end seat 39, respectively, to move the movable clamping block 26 towards the fixed clamping block 25. The movable clamping block 26 is connected with a rope lock 30. Specifically, the end plate 28 is connected with the rope lock 30, which moves the movable clamping block 26 through the end plate 28 and the guide rod 27. The end of the rope lock 30 is connected with a positioning cylinder 31, which can be inserted between the two hole plates 24. The telescopic end of the electric telescopic rod 23 passes through the hole plate 24 and cooperates with the positioning cylinder 31.

[0070] When the spacer rod body 4 is mounted on the ground, the locking rope 30 is pulled to move the positioning cylinder 31 between the two hole plates 24, and then the telescopic end of the electric telescopic rod 23 is extended to pass through the hole plate 24 and enter the end of the positioning cylinder 31, so as to realize the mounting of the spacer rod body 4 and the positioning of the positioning cylinder 31. In the process of moving the positioning cylinder 31 between the two hole plates 24, the locking rope 30 moves the end plate 28, the guide rod 27 and the movable clamping block 26 away from the fixed clamping block 25, and the end plate 28 stretches the tension spring 29 to store energy. In the process of mounting the spacer rod body 4, the wire passes through the inclined part of the expansion frame 32 to enter between the fixed clamping block 25 and the movable clamping block 26, and the wires at both ends of the spacer rod body 4 correspond to between the fixed clamping block 25 and the movable clamping block 26. At this time, the telescopic end of the electric telescopic rod 23 is retracted, first from the positioning cylinder 31, the tension spring 29 makes the movable clamping block 26 close to the fixed clamping block 25 to clamp the wire, and the telescopic end of the electric telescopic rod 23 continues to retract and is separated from the hole plate 24 to release the spacer rod body 4. Therefore, one retraction action of the electric telescopic rod 23 can realize the clamping of the wire and the release of the spacer rod body 4. The unmanned aerial vehicle body 7 in the embodiment adopts a load-carrying unmanned aerial vehicle. When the spacer rod is mounted, a small unmanned aerial vehicle can be used to carry a camera to collect video information at the end of the spacer rod, so as to facilitate rapid installation.

[0071] In the embodiment, the spacer rod body 4 is provided with an insulator at both ends, and the expansion frame 32 bypasses the insulator. In order to prevent the locking rope 30 from contacting the expansion frame 32, a rope passing ring is arranged on the expansion frame 32, and the rope passing ring is used for the locking rope 30 to pass through. At the same time, when the spacer rod body 4 is released, the rope passing ring can avoid excessive shaking of the locking rope 30, and reduce the impact of the positioning cylinder 31.

[0072] The tension spring 29 makes the movable clamping block 26 close to the fixed clamping block 25 to clamp the wire, but the elastic clamping of the tension spring 29 is not stable, and the tension spring 29 will be deformed under force when the wire dances. Therefore, in the embodiment, a check plate 33 is rotationally connected to the end of the spacer rod body 4. Specifically, the check plate 33 is located in an end seat 39, the top wall of the end seat 39 is provided with a groove, one end of the check plate 33 is hinged in the groove, and a V-shaped spring 34 is connected between the check plate 33 and the spacer rod body 4.

[0073] When the movable clamping block 26 moves towards the fixed clamping block 25, the check plate 33 rotates into the groove. After the movable clamping block 26 passes through the check plate 33, the movable clamping block 26 and the fixed clamping block 25 clamp the wire, the V-shaped spring 34 makes the check plate 33 pop out and reset, and the check plate 33 abuts against the side of the movable clamping block 26 away from the fixed clamping block 25. In this way, the check plate 33 limits the movable clamping block 26 from loosening in reverse, avoiding the instability of the movable clamping block 26. The check plate 33 is manually pressed back into the groove, and then the movable clamping block 26 can be moved away from the fixed clamping block 25. In the embodiment, the fixed clamping block 25 forms a U-shaped end of the end seat 39.

[0074] In the prior art, although the unmanned aerial vehicle installation spacer bar is more and more widely used, compared with the traditional installation connection mode, the traditional spacer bar is manually tightened and installed, which can generate a large clamping torque to avoid the misplacement of the spacer bar on the wire. However, the unmanned aerial vehicle installed spacer bar is difficult to achieve sufficient clamping of the wire, which leads to the movement of the spacer bar along the wire, and it is impossible to arrange more spacer bars outside the same section of the wire, thereby failing to guarantee good spacing and anti-wire dancing effect. The above structure in the embodiment cannot avoid this problem.

[0075] In order to solve the problem of insufficient clamping force on the wire, which leads to misplacement of the spacer bar, in the embodiment, the inner side of the fixed clamp block 25 and the movable clamp block 26 has an arc surface matched with the side surface of the wire, and a plurality of spiral strip protrusions 38 extending into the wire surface strand gap are arranged in the arc surface, the spiral strip protrusions 38 are circumferentially distributed and matched with the gap on the surface of the strand. In the prior art, the overhead cable wire uses steel core aluminum strand, and the surface of the aluminum strand has spiral gaps. The spiral strip protrusions 38 in the embodiment extend into the gaps of the aluminum strands, so that the end of the spacer bar body 4 can only rotate around the aluminum strand and misplace along the wire. When the spiral strip protrusions 38 at both ends of the spacer bar body 4 extend into the gaps of the two parallel aluminum strands, the spacer bar body 4 cannot rotate and misplace along the wire. Therefore, the spiral strip protrusions 38 can completely solve the problems of loose, loose, misplacement of the unmanned aerial vehicle installation spacer bar.

[0076] The cross section of the spiral strip protrusion 38 is approximately triangular, one side of the cross section triangular is connected with the clamp block, and the other two sides are concave arc sides, which can be closely matched with the outer sides of the wires.

[0077] In the process of clamping the wire by the fixed clamp block 25 and the movable clamp block 26, the helical strip-shaped protrusions 38 can not correspond to the gaps on the surface of the wire. Therefore, in the embodiment, the inner sides of the fixed clamp block 25 and the movable clamp block 26 are provided with the clamping bodies 35 which slide in the circumferential direction, and the helical strip-shaped protrusions 38 are located on the clamping bodies 35. The outer sides of the clamping bodies 35 are provided with a plurality of arc-shaped sliding blocks 36, and the inner sides of the fixed clamp block 25 and the movable clamp block 26 are provided with the arc-shaped sliding grooves 37 corresponding to the arc-shaped sliding blocks 36. The arc-shaped sliding blocks 36 slide along the inner sides of the arc-shaped sliding grooves 37, and the lengths of the arc-shaped sliding grooves 37 are slightly greater than those of the arc-shaped sliding blocks 36, so that the clamping bodies 35 can slide in the circumferential direction by a small distance, and the sliding distance in the circumferential direction is not less than the circumferential interval between adjacent helical strip-shaped protrusions 38. In the embodiment, the cross sections of the arc-shaped sliding blocks 36 and the arc-shaped sliding grooves 37 are T-shaped. When the helical strip-shaped protrusions 38 cannot correspond to the gaps on the surface of the wire in the process of clamping the wire by the fixed clamp block 25 and the movable clamp block 26, the clamping bodies 35 slide in the circumferential direction, so that the helical strip-shaped protrusions 38 on the inner sides enter the gaps of the stranded wire, and the damage caused by the impact of the helical strip-shaped protrusions 38 is avoided. At the same time, the circumferential sliding of the clamping bodies 35 can still rely on the helical strip-shaped protrusions 38 to avoid the dislocation of the spacer bodies 4 along the wire.
