Description

Technical Field

[0001] The present invention relates to the technical field of unmanned aerial vehicle (UAV) spacer laying, and in particular to a spacer installed based on a UAV. Background Art

[0002] With the expansion and technological advancement of overhead power distribution lines in my country, the weight per unit length of conductors, the weight and diameter of hardware have increased significantly, significantly increasing the risk of galloping on these lines. Galloping can cause serious accidents such as conductor wear, hardware damage, and even line breakage and tripping, threatening the safe and stable operation of the power grid. Currently, spacers are the most widely used anti-galloping device. Due to their excellent insulation and mechanical strength, they can effectively support and restrain conductors of different phases. They are highly effective in suppressing conductor galloping and have become a standard anti-galloping measure for power companies.

[0003] In the existing technology, there is a lack of suitable intelligent and remote operation solutions for the installation of anti-dancing devices for low-voltage distribution network overhead lines. Especially in scenarios such as crossing rivers and complex terrain, traditional construction methods are difficult to meet the high-reliability and high-efficiency installation requirements.

[0004] In addition, when the drone in the existing technology installs the spacer, the chain rope below is easily disturbed by the wind during the flight of the drone, affecting the stability of the high-altitude operation. Moreover, the spacing distances of the distribution network overhead lines are different. The spacer has poor adaptability when laying distribution network overhead lines with different spacing or horizontal heights during installation. Summary of the Invention

[0005] The purpose of the present invention is to solve the problem in the prior art that when a drone is used to install the spacer, the spacer is difficult to be stably laid and installed on the distribution network overhead lines when the spacing distance between the distribution network overhead lines changes, and to propose a spacer based on drone installation.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions: A spacer installed on a drone comprises a drone and a spacer body. A connecting frame is provided at the bottom of the drone, a chain rope and a telescopic assembly are provided at the bottom of the connecting frame, a push-up assembly is provided at the telescopic end of the telescopic assembly, and a locking assembly is provided at the bottom end of the chain rope for locking the spacer body with the overhead line of the distribution network.

[0007] In some embodiments, the locking assembly includes: Support plates provided at both ends of the spacer rod body; A locking box fixed to the connecting post at the bottom end of the chain rope; A fixed clamp and a movable clamp are provided on one side of the support plate away from the spacer rod body. Both the fixed clamp and the movable clamp are provided with a clamping groove adapted to the overhead line of the distribution network.

[0008] In some embodiments, a movable groove is provided in the middle of the support plate, and a sliding groove is provided on one side of the movable groove; a lifting block is provided on one side of the movable clamp; a lifting column is provided in the movable groove, the lifting column passes through the lifting block, and an elastic ball is provided at the bottom of the lifting column; a lifting piece is provided on the top of the lifting column, and the lifting piece is used to pull the lifting column to move upward.

[0009] In some embodiments, a card slot is provided at the bottom of the fixed card, a spring and a card cover are symmetrically provided on the inner side of the card slot, an inner groove is opened in the middle of the card cover, and a card ball is provided on the top of the movable card, and the spring and the card cover are used to clamp and fix the card ball.

[0010] In some embodiments, a connection box is provided between the chain rope and the ejection assembly, a rotating ring, a rotating motor and a second gear are provided inside the connection box, an inner gear ring is provided inside the rotating ring, and the rotating motor drives the inner gear ring to rotate; The telescopic end of the ejection assembly is provided with a clamp, the ejection assembly is fixed to the rotating ring through a connecting rod, and the direction of the ejection assembly is adjusted by rotating the motor; An electromagnetic latch is provided in the clamp for clamping the chain rope when power is turned on.

[0011] In some embodiments, an insulating flexible pad is provided inside the clamping grooves of the fixed clamp and the movable clamp, and the insulating flexible pad is adapted to the clamping grooves.

[0012] In some embodiments, the telescopic assembly drives the ejection assembly and the clamp to move downward along the chain rope, and the position of the chain rope is constrained by the clamp.

[0013] In some embodiments, after the electromagnetic latch in the clamp is energized, the two telescopic components drive the ejection component and the clamp to retract, shortening the length of the chain rope.

[0014] In some embodiments, one of the pushing assemblies is perpendicular to the spacer rod body, and one of the pushing assemblies is parallel to the spacer rod body. The pushing assembly parallel to the spacer rod body pushes the chain rope outward, gradually increasing the distance between the two distribution network overhead lines. At the same time, the pushing assembly perpendicular to the spacer rod body drives one end of the spacer rod body toward the other end of the spacer rod body, which is used for the installation of the spacer rod body between two distribution network overhead lines that are relatively close.

[0015] In some embodiments, after the electromagnetic pin in the clamp is energized, one of the telescopic components drives one of the chain ropes to move upward, and one end of the spacer rod body is tilted upward, which is used to install the spacer rod body of the overhead distribution line at high and low places.

[0016] Compared with the prior art, the present invention provides a spacer rod installed based on a drone, which has the following beneficial effects.

[0017] 1. This invention uses a drone to carry the spacer rod body, enabling rapid remote installation of overhead distribution line spacers, eliminating the risks of manual tower climbing. It is particularly suitable for use in complex terrain such as river crossings and mountainous areas. During flight, the clamp restrains the chain rope, preventing entanglement. Shortening the chain rope length reduces wind interference, improving stability and precision during high-altitude operations.

[0018] 2. The present invention is aimed at distribution network overhead lines located at different horizontal planes. By contracting one of the telescopic components, the main body of the spacer is tilted to adapt to the height difference between the two distribution network overhead lines. Subsequently, the locking component is used to complete the connection between the lower line and the higher line respectively, solving the problem that traditional installation tools are difficult to handle the installation of the main body of the spacer for non-horizontal lines.

[0019] 3. When the spacing between overhead lines in the distribution network is less than the length of the spacer bar body, the present invention drives the pushing assembly to rotate through the rotating motors in the two connection boxes, so that one of the two pushing assemblies is perpendicular to the spacer bar body and the other pushing assembly is parallel to the spacer bar body. The two pushing assemblies slowly extend in coordination, and while keeping the card slot corresponding to the line, the angle of the spacer bar is fine-tuned to restore the spacer bar body to a vertical state, thereby ensuring that the spacer bar body stably supports the distribution network overhead lines.

[0020] 4. The locking assembly of the present invention is driven by the first gear and the outer rack and the elastic ball structure. The lifting column pushes the movable clamp to fix the distribution network overhead line. The spring and the clamping cover cooperate to clamp the clamping ball. After the installation is completed, the elastic ball is continuously lifted upward by the lifting column, and the elastic ball is deformed and separated from the spacer bar body, and the laying of the spacer bar body is completed based on automation.

[0021] Other advantages, objects and features of the present invention will be described in part in the following description; and in part will be apparent to those skilled in the art based on an examination of the following; or may be taught from the practice of the invention.

[0037] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0038] Reference Figure 1-14 A spacer rod installed based on a drone includes a drone 1 and a spacer rod body 2. A connecting frame 3 is provided at the bottom of the drone 1. Two connecting frames 3 are symmetrically provided at the bottom of the drone 1. A chain rope 4 and a telescopic component 5 are provided at the bottom of the connecting frame 3. The telescopic end of the telescopic component 5 is provided with a pushing assembly 6. The pushing assembly 6 is an electric push rod. The pushing assembly 6 is used to adjust the position of the spacer rod body 2 through the chain rope 4.

[0039] The bottom end of the chain 4 is equipped with a locking assembly, which is used to lock the spacer body 2 to the distribution network overhead line. The locking assembly includes a support plate 201 and a locking box 204. The support plates 201 are installed at both ends of the spacer body 2, and the locking box 204 is installed at the bottom end of the chain 4. The bottom end of the chain 4 is configured as a connecting post 401, and the locking box 204 is fixedly connected to the connecting post 401.

[0040] A fixed clamp 202 and a movable clamp 203 are provided on the side of the support plate 201 away from the spacer rod body 2, and a clamping groove compatible with the distribution network overhead line is provided on the fixed clamp 202 and the movable clamp 203. A movable groove 2011 is provided in the middle of the support plate 201, and a slide groove 2013 is provided on the side of the movable groove 2011 close to the movable clamp 203. A lifting block 2031 corresponding to the slide groove 2013 is provided on the side of the movable clamp 203 close to the support plate 201, and a through hole 2032 is provided on the lifting block 2031. A lifting column 2012 is provided inside the movable groove 2011, and the lifting column 2012 passes through the through hole 2032. A lifting member is provided on the top of the lifting column 2012, and the lifting member is used to pull the lifting column 2012 to move upward.

[0041] The bottom of the fixed clamp 202 is provided with a slot 2021, and springs 2022 are symmetrically arranged inside the slot 2021. A snap cover 2023 is provided at the end of the two springs 2022 that are close to each other. An inner groove 2024 is provided in the middle of the snap cover 2023. A notch is provided at the bottom of the slot 2021 for the snap ball 2033 to enter the slot 2021. A snap ball 2033 is provided at the top of the movable clamp 203, which corresponds to the slot 2021 and mates with the inner groove 2024.

[0042] The lifting column 2012 includes a connecting shaft 20121 and a lifting cylinder 20122. A threaded hole is provided in the middle of the lifting cylinder 20122. A threaded rod 20123 is provided on the top of the connecting shaft 20121. An external rack 20125 is provided on one side of the lifting cylinder 20122. An elastic ball 20124 is provided at the bottom of the connecting shaft 20121.

[0043] Specifically, the lifting member includes a lifting slot 2042 opened on the locking box 204, the lifting slot 2042 corresponds to the position of the lifting column 2012, a first gear 2041 is provided inside the locking box 204, the first gear 2041 is driven by the locking motor, and an external rack 20125 is provided on one side of the lifting cylinder 20122, and the first gear 2041 is meshed and connected with the external rack 20125.

[0044] The telescopic component 5 is an electric push rod, the telescopic end of the electric push rod is fixedly connected to the connecting box 8, the telescopic end of the pushing component 6 is provided with a clamp 601, and the top of the pushing component 6 is provided with a connecting rod 602. The connecting rod 602 corresponds to the slide 801, and the top of the connecting rod 602 is fixedly connected to the rotating ring 802.

[0045] In the present invention, the connecting frame 3, the chain 4, the telescopic assembly 5 and the pushing assembly 6 serve as a module to connect the drone 1 with the spacer rod body 2, and the connecting frame 3 and the drone 1 are detachably connected.

[0046] During use, the first gear 2041 drives the lifting cylinder 20122 to move downward by engaging with the external rack 20125, and the two movable grooves 2011 at both ends of the spacer rod body 2 correspond to the two lifting cylinders 20122 respectively, and then the connecting shaft 20121 passes upward from the bottom of the movable groove 2011, and the connecting shaft 20121 is screwed to make the threaded rod 20123 screwed into the threaded hole of the lifting cylinder 20122. At this time, the elastic ball 20124 is close to the bottom of the movable groove 2011, completing the connection between the spacer rod body 2 and the bottom end of the chain rope 4. In the initial state, the elastic ball 20124 is always located outside the support plate 201 and close to the bottom of the movable groove 2011. When the drone 1 lifts the spacer rod body 2, the two elastic balls 20124 support the bottom ends of the spacer rod body 2 from the bottom.

[0047] The drone 1 is started, and the drone 1 drives the spacer bar body 2 to the required installation position of the distribution network overhead line. During the flight of the drone 1, the telescopic component 5 drives the pushing component 6 and the clamp 601 to move downward along the chain rope 4. The two clamps 601 simultaneously constrain the position of the chain rope 4 to prevent the two chain ropes 4 from getting knotted or entangled with each other at the bottom of the drone 1, especially for the installation of the lighter spacer bar body 2.

[0048] On the other hand, an electromagnetic pin is provided inside the clamp 601. When the electromagnetic pin is energized, the telescopic end of the electromagnetic pin is pushed outward, cooperating with the clamp 601 to clamp the chain 4. According to the needs of use, the telescopic component 5 first drives the pushing component 6 and the clamp 601 to move downward. After the electromagnetic pin is energized to clamp the chain 4, the telescopic component 5 drives the pushing component 6 and the clamp 601 to retract again, and the chain 4 located above the pushing component 6 is folded. As the telescopic component 5 retracts, the length of the chain 4 is reduced, and the distance between the drone 1 and the spacer rod body 2 is shortened. By shortening the length of the chain 4, the influence of wind interference on the drone 1 during high-altitude operation is reduced, the space limitation of the operating environment is reduced, and the stability of the spacer rod body 2 during the operation of the drone 1 is improved, thereby improving the operating accuracy and operation safety.

[0049] When the spacer body 2 is connected and installed with the distribution network overhead line, the drone 1 is located at the top of the distribution network overhead line, the two clamps 601 are located at the same horizontal plane, and driven by the telescopic component 5, the two clamps 601 are close to the spacer body 2. At this time, the clamps 601 are still located on the chain rope 4, and the two chain ropes 4 are constrained by the two clamps 601. At this time, the two ends of the spacer body 2 are located between the two distribution network overhead lines, and the pushing component 6 located on the inner side of the distribution network overhead line drives one end of the spacer body 2 to push one of the distribution network overhead lines through the clamp 601. , the spacer rod body 2 moves in the pushing direction, and the distribution network overhead line is located in the clamping groove between a set of fixed clamps 202 and movable clamps 203, and then the first gear 2041 in the locking box 204 close to the side is started by the drive of the locking motor, and the first gear 2041 drives the lifting column 2012 to move upward through the outer rack 20125. It should be noted that when the lifting column 2012 moves upward, the elastic ball 20124 is first slightly deformed and enters the movable groove 2011 upward. After the elastic ball 20124 contacts the bottom of the lifting block 2031, as shown Figure 14As shown, the elastic supporting force of the spring 2022 is not enough to make the elastic ball 20124 continue to deform and pass through the through-hole 2032. As the lifting column 2012 continues to move upward, the elastic ball 20124 pushes the lifting block 2031 to move upward along the slide groove 2013. When the lifting block 2031 moves upward, the receiving ball 2033 enters through the notch at the bottom of the slot 2021. The edges of the two receiving covers 2023 are smooth curved surfaces. When the receiving ball 2033 is pushed up, the two receiving covers 2023 retract backward under the elastic supporting force of the two springs 2022. When the lifting block 2031 moves upward to the top, the two receiving balls 2033 are respectively inserted into the two sets of receiving covers 2023, thereby completing the fixing of the fixed card 202 and the movable card 203 to the distribution network overhead line. In the same manner, the other end of the spacer body 2 is driven toward the other distribution network overhead line by the clamp 601 of another pushing assembly 6 located on the inner side of the distribution network overhead line, so that the distribution network overhead line is located in the clamping groove between the other set of fixed clamps 202 and the movable clamp 203. Then, the first gear 2041 in the locking box 204 near this side is activated, driving the lifting column 2012 to move upward, pushing the movable clamp 203 and the fixed clamp 202 to complete the clamping and fixing of the other distribution network overhead line. Finally, the two first gears 2041 continue to drive the two lifting columns 2012 upward respectively. At this time, the elastic ball 20124 continues to deform and shrink under the upward traction force of the lifting column 2012. As the lifting column 212 continues to pull upward, it passes through the perforation 2032 and the movable groove 2011 in sequence, and the lifting column 212 is separated from the spacer body 2, completing the installation of the spacer body 2 on the distribution network overhead line.

[0050] like Figure 13 As shown, in order to improve the stability of the snap-in ball 2033 in the inner groove 2024 and prevent the snap-in ball 2033 from escaping from the snap-in cover 2023, the snap-in ball 2033 and the snap-in cover 2023 are improved. Specifically, the bottom of the snap-in ball 2033 is set to be flat, and the inner side of the snap-in cover 2023 is provided with a notch adapted to the flat bottom.

[0051] In actual use, operators found that parts of the two distribution network overhead lines would be close to each other. At this time, the distance between the two distribution network overhead lines was less than the length of the spacer rod body 2. In this regard, during use, the drone 1 can be operated to rotate and change the angle of the spacer rod body 2, so that the spacer rod body 2 and the distribution network overhead line are not perpendicular. When the spacer rod body 2 is located between the two distribution network overhead lines, the drone 1 is operated to rotate and reset, so that the spacer rod body 2 supports and fixes the two distribution network overhead lines.

[0052] However, due to the friction between the two sets of fixed clamps 202 and the movable clamps 203 and the distribution network overhead lines, the spacer body 2 will be stuck on the inside of the distribution network overhead lines, resulting in the spacer body 2 being unable to follow the driving of the drone 1 on the chain rope 4 and regain perpendicularity to the distribution network overhead lines. When the tilt angle of the spacer body 2 is too large, the spacer body 2 will find it difficult to stably support the two distribution network overhead lines. In this regard, the following improvements are made: A connecting box 8 is provided between the chain rope 4 and the pushing assembly 6. A middle hole 805 corresponding to the chain rope 4 is provided in the middle of the connecting box 8. The chain rope 4 passes through the middle hole 805. A slide 801 is provided at the bottom of the connecting box 8. The slide 801 is semi-annular. An annular groove is provided on the top of the slide 801. A rotating ring 802 is connected to the inside of the annular groove. An inner gear ring 802 is provided on the inner side of the rotating ring 802. A second gear 803 and a rotating motor 804 are provided inside the connecting box 8. The second gear 803 is meshed with the inner gear ring 8021.

[0053] When in use, the rotating motor 804 drives the ejection assembly 6 to rotate around the center point of the clamp 601 through the cooperation of the second gear 803 and the inner gear ring 8021, thereby adjusting the direction of the ejection assembly 6. The rotating motor 804 adjusts one ejection assembly 6 to an angle perpendicular to the spacer rod body 2, and the telescopic assembly 5 remains in the extended state. Figure 12 As shown, the distance between the two distribution network overhead lines is gradually increased by slowly pushing the chain rope 4 outward from the inside of the chain rope 4 through the pushing assembly 6 parallel to the spacer bar body 2. At the same time, the pushing assembly 6 perpendicular to the spacer bar body 2 drives one end of the spacer bar body 2 to slowly approach the other end of the spacer bar body 2. Specifically, when the pushing assembly 6 parallel to the spacer bar body 2 pushes the chain rope 4 outward, the distance between the two distribution network overhead lines increases. At the same time, the pushing assembly 6 perpendicular to the spacer bar body 2 pushes the other chain rope 4 forward to shorten the distance between the ends of the two spacer bar bodies 2. After completing the distance between the ends of the spacer bar body 2, the two distribution network overhead lines will clamp the two ends of the spacer bar body 2 inward again, repeat the cooperation action of the above two pushing assemblies 6, and gradually complete the auxiliary correction of the spacer bar body 2, so that the spacer bar body 2 and the two distribution network overhead lines remain vertical.

[0054] When the spacer bar body 2 is installed, when the inclination angle of the spacer bar body 2 is small, the angle of the spacer bar body 2 can be adjusted by the above adjustment method, so that the spacer bar body 2 and the distribution network overhead line remain vertical, ensuring the stability of the spacer bar body 2 in supporting the distribution network overhead line.

[0055] The slow movement process always keeps the two sets of fixed clips 202 and the movable clips 203 corresponding to the distribution network overhead lines. When the spacer body 2 and the distribution network overhead lines are perpendicular to each other, the lifting column 2012 is driven upward by the first gear 2041 to dock the fixed clips 202 and the movable clips 203, completing the clamping and fixing of the distribution network overhead lines. Among them, the inner side of the clamping grooves of the fixed clips 202 and the movable clips 203 is provided with an insulating flexible pad. The insulating flexible pad prevents the fixed clips 202 and the movable clips 203 from hard friction with the distribution network overhead lines when the spacer body 2 contacts the distribution network overhead lines, resulting in damage to the distribution network overhead lines. The insulating flexible pad is adapted to the clamping grooves of the fixed clips 202 and the movable clips 203.

[0056] In addition, the above solution is applicable to the auxiliary correction of the position of the spacer rod body 2 when the maximum extension length of the telescopic assembly 5 cannot reach the connecting column 401, that is, when the chain 4 is long. Figure 11 As shown, the telescopic component 5 can directly drive the connection box 8, the pushing component 6 and the clamp 601 to fall to the connection column 401 at the bottom end of the chain rope 4. Through the limiting effect of the telescopic component 5 on the connection box 8, the pushing component 6 and the support in the extended state, and the clamp 601 on the connection column 401, when the drone 1 is operated and rotated, the spacer rod body 2 is rotated synchronously. After the two groups of fixed clips 202 and the movable clips 203 at the ends of the spacer rod body 2 respectively correspond to the two distribution network overhead lines, the drone 1 is operated to rotate and reset, and the tilted spacer rod body 2 rotates synchronously with the drone 1. During the rotation process, the distance between the two distribution network overhead lines gradually increases until the spacer rod body 2 is perpendicular to the distribution network overhead line, and the two groups of fixed clips 202 and the movable clips 203 clamp and fix the two distribution network overhead lines.

[0057] In order to improve the adaptability of the present invention to special line layouts, for example, when the spacer body 2 is installed on two overhead distribution lines located at different levels, the following improvements are made to the above solution: When in use, the drone 1 is first operated to move to the installation position of the distribution network overhead line, and then the two telescopic components 5 are extended downward, and then the electromagnetic pins in the two clamps 601 are energized to clamp and lock the chain rope 4. Then, the telescopic component 5 corresponding to the high distribution network overhead line is contracted, so that the end of the spacer body 2 close to the high distribution network overhead line is tilted upward, and the drone 1 is operated to move so that the fixed clamp 202 and the movable clamp 203 at the bottom end of the spacer body 2 are docked with the low distribution network overhead line. At this time, the first gear 2041 corresponding to the low distribution network overhead line drives the lifting column 2012 to move upward, completing the clamping of the low distribution network overhead line; The distribution network overhead line itself is not in a taut state and has a certain elastic deformation ability. Then, the drone 1 is operated to make the spacer rod body 2 move along with the movement of the drone 1, so that the top of the spacer rod body 2 is connected with the high distribution network overhead line. Then, the first gear 2041 close to the top of the spacer rod body 2 drives the lifting column 2012 to move upward, so that the fixed clamp 202 and the movable clamp 203 at the top of the spacer rod body 2 are connected with the high distribution network overhead line. The two first gears 2041 continue to drive the lifting column 2012 to move upward, and the lifting column 2012 is separated from the spacer rod body 2, completing the installation of the spacer rod body 2 on the distribution network overhead lines at different horizontal planes.

[0058] As an optional solution for the above-mentioned drone 1 to drive the spacer rod body 2 to rotate, a rotating component can be set between the drones 1 and 1, the fixed end of the rotating component is fixedly connected to the drone 1, and the rotating end of the rotating component is fixedly connected to the connecting frame 3. The rotating component replaces the drone 1 to rotate, thereby changing the angle of the spacer rod body 2.

[0059] like Figure 2 As shown, in order to adapt to spacer rod bodies 2 of different lengths, the connecting frame 3 includes a fixed frame and a movable frame. The movable frame is fixed to the fixed frame by bolts, and a plurality of fixing screw holes are provided on the fixed frame for adjusting the spacing between the movable frames, and then adjusting the spacing between the two chain ropes 4, so that the connecting frame 3 can adapt to spacer rod bodies 2 of different lengths.
