Description

Technical Field

[0001] This application relates to the field of cable maintenance technology, specifically to a docking assembly, docking device, and cable maintenance equipment. Background Technology

[0002] With the continuous development of the power system, high-voltage transmission lines, as the backbone network for power transmission, are of paramount importance for safe and stable operation. However, high-altitude cables are exposed to a complex and ever-changing natural environment for extended periods, facing numerous challenges and being highly susceptible to problems such as insulation aging, mechanical damage, and connection failures.

[0003] To reduce the safety risks of maintenance personnel working at heights, drones have been used in recent years to deploy inspection robots onto overhead power lines for automated maintenance. However, current drone deployment methods involve the drone flying above the power line and then lowering the robot onto it. Figure 1 As shown, since high-altitude cables are generally arranged in a triangular pattern of three wire bundles, when the inspection robot is deployed onto the two lower wire bundles, the drone is close to the upper wire bundle. The drone is easily damaged by the electromagnetic field of the upper wire bundle, and both the drone and the inspection robot are at great risk of damage. Utility Model Content

[0004] In view of this, this application provides a docking assembly that can solve the problem of UAVs being easily damaged by electromagnetic field breakdown. This application also provides a docking device having the above-mentioned docking assembly, and a cable repair device having the docking device.

[0005] To achieve the above objectives, this application provides the following technical solution:

[0006] A docking assembly, capable of docking and disconnecting an inspection robot from overhead cables, comprising:

[0007] The frame has a housing space for accommodating the inspection robot and a side opening that allows the overhead cable to enter the housing space, and the frame can limit the installation position of the inspection robot.

[0008] A docking frame is provided on the side opening side of the frame frame to guide the high-altitude cable from the side opening into the receiving space;

[0009] A locking element, disposed on the docking frame, is capable of limiting the position of the docking frame relative to the high-altitude cable.

[0010] Optionally, the docking frame includes:

[0011] A first guide member has a first end and a second end with a height less than the first end. The first end is located outside the side opening, and the second end is located inside the side opening, for guiding the high-altitude cable from the side opening into the receiving space.

[0012] A blocking element, connected to the second end, blocks the high-altitude cable from entering the receiving space, thereby positioning the high-altitude cable;

[0013] The blocking member is aligned with the rollers of the inspection robot housed in the accommodating space, so that the blocking member positions the high-altitude cable at the docking position with the inspection robot.

[0014] Optionally, the locking member is connected to the first guide member, and the locking member includes a locked state and an unlocked state, wherein:

[0015] When the high-altitude cable enters the receiving space through the first guide, the locking member is in the unlocked state;

[0016] When the high-altitude cable moves to contact the blocking member, the locking member switches to a locked state, so that the locking plate of the locking member and the blocking member are respectively located on both sides of the high-altitude cable.

[0017] Optionally, it also includes a driving component, which is pulsatorically connected to the locking component, and the driving component is capable of driving the locking component to switch between the locked state and the unlocked state.

[0018] Optionally, the locking element is a linkage mechanism, which includes:

[0019] A drive board, one end of which is connected to the drive component;

[0020] A locking plate, the middle part of which is rotatably connected to the other end of the driving plate, one end of which is rotatably connected to the first guide member, and the other end of which is a free end;

[0021] The driving member drives the driving plate to rotate so that the locking plate can protrude from the first guide member.

[0022] Optionally, the linkage mechanism further includes a connecting plate, one end of which is rotatably connected to the other end of the drive plate, and the other end of which is rotatably connected to the middle of the locking plate.

[0023] Optionally, it may also include a blocking plate connected to the first guide member, and the blocking plate abuts against the locking plate when the locking member is in the unlocked state.

[0024] Optionally, the docking frame further includes a second guide disposed below the first guide, the second guide including a third end located outside the side opening and a fourth end located in the receiving space, the fourth end being higher than the third end.

[0025] A docking device includes a docking assembly, a connecting frame, and an aircraft that drives the docking assembly to fly, wherein:

[0026] The docking assembly is the docking assembly described above, and the connecting frame is connected to the frame and located above the frame, for connecting the aircraft.

[0027] A cable inspection device includes an inspection robot and a docking device for connecting and disconnecting the inspection robot from an overhead cable, wherein the docking device is the aforementioned docking device.

[0028] The docking assembly provided in this application can be used for docking and separating inspection robots from overhead cables. Its frame has a receiving space. When deploying the inspection robot to the overhead cable, the inspection robot can be placed in the receiving space first, and the drone and the frame can be connected by a connecting frame. Then, the drone is controlled to take off, so that the docking assembly carries the inspection robot to a high altitude to approach the overhead cable. The opening on the frame that allows the overhead cable to enter the receiving space is set on the side, and the docking frame used to guide the overhead cable into the receiving space is also set corresponding to the side opening. In this way, the overhead cable can enter the receiving space from the side of the frame in a translational manner. During separation, the docking assembly moves in the opposite direction under the drive of the drone, so that the overhead cable can be moved out of the receiving space through the side opening. In other words, this docking component achieves lateral docking with the high-altitude cable through translation. When deploying the inspection robot to the lower two of the three wire harnesses distributed in a triangular pattern, it can prevent the drone from getting too close to the upper wire harness, so that the drone will no longer be damaged by the electromagnetic field of the upper wire harness. The working safety of the drone and the inspection robot is significantly improved.

[0029] In addition, the docking assembly includes a locking element mounted on the docking frame. This locking element limits the position of the docking frame relative to the overhead cable. As the overhead cable slides into the receiving space from the side of the frame, and the docking assembly moves to dock with the overhead cable and inspection robot, the locking element locks the docking frame and the overhead cable. The inspection robot then moves out of the docking assembly along the overhead cable to inspect and repair it. By incorporating the locking element, the stability of the docking assembly and the overhead cable docking is improved. Attached Figure Description

[0046] The technical solutions of the embodiments of this application will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0047] like Figures 2-11As shown, this application provides a docking assembly, which can at least be used to dock and separate the inspection robot 5 from the high-altitude cable 4, or it can also be applied to other docking and separation scenarios, which this application does not limit. This docking assembly mainly includes a frame 1, a docking frame 2, and a locking member 3. The frame 1 is the main structure of the docking assembly, which is used to support and set other structures of the docking assembly such as the docking frame 2 and the connecting frame 7. As the name suggests, the frame 1 is frame-shaped, and can be a cubic or cuboid structure formed by connecting pipes, rods, and / or plates. The space inside the frame is the accommodating space for accommodating and connecting (e.g., hanging) the inspection robot 5. In order to optimize the structure, the pipes, rods, and / or plates that enclose the accommodating space also form The system includes outriggers for supporting the docking assembly, inspection robot 5, and drone (drone not shown in the diagram) on the ground. The docking frame 2, located at the side opening on the frame 1, guides the overhead cable 4 from the side opening into the receiving space. This ensures that the overhead cable 4 and the side opening are aligned when the docking assembly approaches it, allowing the overhead cable 4 to enter the receiving space containing the inspection robot 5 more conveniently, quickly, and accurately when the docking assembly moves under the drone's influence. A locking element 3 is mounted on the docking frame 2. Locking component 3 limits the position of docking frame 2 relative to the aerial cable 4. Locking component 3 locks the connection position between docking frame 2 and aerial cable 4. That is, when the aerial cable 4 is guided into the receiving space and the inspection robot 5 completes docking with the aerial cable 4, locking component 3 limits the position of docking frame 2 and aerial cable 4, preventing the aerial cable 4 from moving further. (It should be noted that in actual situations, the aerial cable 4 does not move; rather, the docking assembly moves under the influence of the drone. However, this is explained for the sake of clarity.) This application describes the relative movement between the overhead cable 4 and the docking assembly as the movement of the overhead cable 4 (this description should not be construed as a limitation or misinterpretation of this application), in order to limit the overhead cable 4 within the receiving space. When designing the docking assembly, the position of the docking frame 2 positioning the overhead cable 4 is aligned with the position of the rollers of the inspection robot 5 within the receiving space (this alignment refers to alignment in the axial and / or vertical direction of the overhead cable 4). Thus, docking between the overhead cable 4 and the inspection robot 5 can be achieved when the overhead cable 4 is positioned. For example, the locking member 3 can be limited by abutting against the overhead cable 4, or by engaging with the overhead cable 4, or by magnetically attracting the overhead cable 4, etc.

[0048] It should be noted that the inspection robot 5 is existing equipment, and its structure can be found in [reference needed]. Figure 3As shown, the docking method between the aerial cable 4 and the inspection robot 5 can be as follows: the inspection robot 5 is suspended on the frame 1 by a hook. After the aerial cable 4 and the inspection robot 5 are aligned, the aerial cable 4 is located below the rollers of the inspection robot 5. Then, the drone is controlled to move down a certain distance (this distance is much smaller than the distance between the upper and lower wiring harnesses). During the downward movement, the aerial cable 4 carries the inspection robot 5 (i.e., the rollers of the inspection robot 5 are hooked on the aerial cable 4). Because the inspection robot 5 is carried by the aerial cable 4, it will not continue to move down with the drone and the docking components. This allows the inspection robot 5 to detach from the hook and separate from the frame 1. After that, the inspection robot 5... The robot can move along the high-altitude cable 4 by rotating its rollers, and then move out of the housing space to perform inspection tasks (the inspection tasks include the inspection, examination and repair of the high-altitude cable 4). When it is necessary to retrieve the inspection robot 5, the docking component is first docked with the high-altitude cable 4, and then the inspection robot 5 is moved along the positioned high-altitude cable 4 to the housing space. At this time, the rollers of the inspection robot 5 are aligned with the hooks on the frame 1. Then, the drone drives the docking component to move down so that the hooks hook the inspection robot 5. The drone then drives the docking component and the inspection robot 5 to rise so that the inspection robot 5 is separated from the high-altitude cable 4. Finally, the drone drives the docking component and the inspection robot 5 back to the ground.

[0049] The aforementioned docking assembly places the opening for the high-altitude cable 4 to enter and exit on the side of the frame 1. When deploying the inspection robot 5 to the lower two wire harnesses of the three wire harnesses arranged in a triangular pattern, the drone only needs to fly the docking assembly to the same height as the lower wire harnesses, and then move it horizontally to dock with the high-altitude cable 4. This side docking method ensures a greater distance between the drone and the upper wire harness of the three wire harnesses arranged in a triangular pattern, preventing the drone from being damaged by the electromagnetic field of the upper wire harness. The operational safety of the drone and the inspection robot 5 is significantly improved. Furthermore, when the docking assembly moves to dock with the high-altitude cable 4 and the inspection robot 5, the locking element 3 locks the docking frame 2 and the high-altitude cable 4. Then, the inspection robot 5 moves out from the docking assembly along the high-altitude cable 4 to inspect and repair the high-altitude cable 4. By setting the locking element 3, the stability of the docking assembly and the high-altitude cable 4 docking is improved.

[0050] In optional embodiments, such as Figure 2As shown, the docking frame 2 includes a first guide member 21, with a first end 211 and a second end 212 with a height less than the first end 211. The first end 211 is located outside the side opening, and the second end 212 is located inside the side opening, so as to guide the high-altitude cable 4 from the side opening into the receiving space. In this structure, the tubular or rod-shaped first guide member 21 is inclined, or a slope or curved surface is provided on the plate-shaped first guide member 21 so that the first guide member 21 has two ends with different heights. Among these two ends, the first end 211 located outside the side opening is higher than the second end 212 located inside the side opening. Furthermore, the height of the first end 211 can be greater than the height of the upper edge of the side opening. In this way, by setting the first guide member 21, the docking space of the docking components can be larger. Even if the high-altitude cable 4 located outside the side opening is higher than the side opening to a certain extent, it can still be guided by the first guide member 21 to enter the side opening more easily and quickly. In addition, the height of the second end 212 is less than the height of the upper edge of the side opening, so that the high-altitude cable 4 can be guided more accurately to the docking position (i.e., the position aligned with the roller of the inspection robot 5), thereby making subsequent docking easier to achieve.

[0051] At the same time, such as Figure 2 As shown, the docking frame 2 also includes a blocking member 22, which is connected to the second end 212 of the first guide member 21 and is used to block the high-altitude cable 4 from entering the receiving space to achieve the positioning of the high-altitude cable 4; wherein, the blocking member 22 is aligned with the rollers of the inspection robot 5 housed in the receiving space (this alignment refers to alignment in the extension direction and / or vertical direction of the high-altitude cable 4) so ​​that the blocking member 22 positions the high-altitude cable 4 at the docking position with the inspection robot 5. This blocking component 22 is also composed of pipes, rods, or plates. That is, the blocking component 22 can be a blocking pipe, a blocking rod, or a blocking plate 6. It is vertically connected to the second end 212 of the first guide component 21, which has a smaller height. When the high-altitude cable 4 slides down the inclined first guide component 21 to the innermost end (i.e., the second end 212) of the first guide component 21, the high-altitude cable 4 is blocked by the blocking component 22 and cannot continue to move deeper into the accommodating space. In this way, the high-altitude cable 4 is positioned. At the same time, as shown in Figures 1 and 2, since the blocking component 22 and the roller of the inspection robot 5 are aligned, the high-altitude cable 4 blocked by the blocking component 22 is located exactly below the roller (preferably moved into the groove of the roller). Then, the inspection robot 5 is moved down and detached from the frame 1 to realize the docking of the inspection robot 5 and the high-altitude cable 4. The inspection robot 5 is mounted on the high-altitude cable 4 by the roller and can walk on the high-altitude cable 4 by the rotation of the roller.

[0052] Thus, by including the first guide member 21 and the blocking member 22 in the docking frame 2, not only can the convenience and success rate of docking be improved, but it can also make it easier to dock the inspection robot 5 and the high-altitude cable 4, making the working performance of the docking component provided in this application more outstanding.

[0053] like Figures 4-11 As shown, locking member 3 is connected to the first guide member 21. Locking member 3 includes a locked state and an unlocked state. It should be noted that the locked state refers to the state in which locking member 3 limits the position of docking frame 2 relative to the high-altitude cable 4 (e.g., Figure 10 As shown), the unlocked state refers to the state where the locking element 3 is not limiting the connection between the docking frame 2 and the high-altitude cable 4 (as shown). Figures 4-9 (As shown). When the high-altitude cable 4 enters the receiving space via the first guide 21, the locking member 3 is in the unlocked state. When the high-altitude cable 4 moves to abut against the blocking member 22, the locking member 3 switches to the locked state, so that the locking plate 32 of the locking member 3 and the blocking member 22 are respectively located on both sides of the high-altitude cable 4. Specifically, during the docking process of the high-altitude cable 4 through the docking assembly, that is, during the movement of the high-altitude cable 4 along the first guide 21, the locking member 3 is kept in the unlocked state. This prevents the locking member 3 from obstructing the relative movement of the first guide 21 and the high-altitude cable 4, allowing the docking assembly to efficiently dock the inspection robot 5 and the high-altitude cable 4. When the high-altitude cable 4 moves to abut against the blocking member 22, that is, when the docking assembly docks the inspection robot 5 with the high-altitude cable 4, the locking member 3 switches to the locked state. In the locked state, the locking plate 32 and the blocking member 22 are respectively located on both sides of the high-altitude cable 4, thus limiting the relative position of the docking frame 2 and the high-altitude cable 4. By using locking plate 32 and blocking member 22, the high-altitude cable 4 is finally limited on both sides, which can improve the limiting effect on docking frame 2 and high-voltage cable. Moreover, the locking member 3 has a simple structure and a significant limiting effect.

[0054] It should be noted that the extension of the limiting plate out of the first guide member 21 can be by movement and / or rotation.

[0055] like Figures 9-11As shown, the docking assembly also includes a drive component (not shown in the figure), which is connected to the locking component 3 via a transmission mechanism. The drive component can drive the locking component 3 to switch between a locked state and an unlocked state. When the first guide 21 guides the aerial cable 4 into the receiving space from the side opening, the drive component is inactive, and the locking component 3 is in an unlocked state. When the aerial cable 4 moves to the position where it abuts against the blocking component 22, that is, when the inspection robot 5 has docked with the aerial cable 4, the drive component activates to drive the locking plate 32 of the locking component 3 to move and protrude from the first guide 21, thereby locking the docking frame 2 and the aerial cable 4. Here, by setting the drive component, the switching of the locking component 3 between the unlocked and locked states can be achieved efficiently, improving switching efficiency and stability during switching.

[0056] It should also be noted that the switching between the unlocked and locked states of the locking member 3 can be achieved without the aforementioned driving component. For example, a locking switch can be installed on the blocking member 22. When the high-altitude cable 4 moves to the position where it abuts against the blocking member 22, the high-altitude cable 4 presses the locking switch to release the locking plate 32, causing the locking plate 32 to protrude from the first guide member 21, thereby completing the limiting of the docking frame 2. After docking is completed, the docking frame 2 moves in the opposite direction, releasing the pressing of the locking switch, causing the locking plate 32 to retract back to the unlocked state of the locking member 3.

[0057] like Figures 9-11 As shown, the locking element 3 is a linkage mechanism, which includes a drive plate 31 and a locking plate 32. One end of the drive plate 31 is connected to the drive element; the middle part of the locking plate 32 is rotatably connected to the other end of the drive plate 31, one end of the locking plate 32 is rotatably connected to the first guide member 21, and the other end of the locking plate 32 is a free end; wherein, the drive element drives the drive plate 31 to rotate so that the locking plate 32 can protrude from the first guide member 21. Specifically, the drive element is a servo motor disposed at one end of the drive plate 31 (the servo motor can be disposed at...). Figure 11 (As shown in position B), the servo motor can apply a driving force to the drive plate 31, causing the other end of the drive plate 31 to rotate around one end of the drive plate 31. Since the other end of the drive plate 31 is connected to the middle of the locking plate 32, the other end of the drive plate 31 will drive the locking plate 32 to rotate. Since one end of the locking plate 32 is rotatably connected to the first guide member 21, the free end of the other end of the locking plate 32 will rotate, allowing the free end of the locking plate 32 to protrude from the first guide member 21, thereby limiting the position of the locking plate 32 relative to the high-altitude cable 4. Here, by setting the locking member 3 as a linkage mechanism, the stability of the transmission can be improved, and the linkage mechanism has the advantages of simple structure, high reliability, and strong adaptability.

[0058] like Figures 9-11As shown, the linkage mechanism also includes a connecting plate 33, one end of which is rotatably connected to the other end of the drive plate 31, and the other end of which is rotatably connected to the middle of the locking plate 32. Specifically, when the locking member 3 needs to be switched to the locked state, the drive member drives the drive plate 31 to rotate, so that the other end of the drive plate 31 rotates around the one end of the drive plate 31. The connecting plate 33, which is connected to the other end of the drive plate 31, is subjected to a force from the other end of the drive plate 31 toward the middle of the locking plate 32. The connecting plate 33 transmits the force to the locking plate 32, and the free end of the locking plate 32 rotates around the one end of the locking plate 32 as an axis, so that the free end of the locking plate 32 protrudes from the first guide member 21, thereby limiting the connection frame 7 relative to the high-altitude cable 4. Here, by setting the connecting plate 33, the stability of the rotational force transmitted from the drive plate 31 to the locking plate 32 can be improved, the rotation amplitude of the locking plate 32 can be increased, and the stability of the locking member 3 limiting the connection frame 7 can be improved.

[0059] like Figures 9-11 As shown, the docking assembly also includes a blocking plate 6 connected to the first guide member 21, and the blocking plate 6 abuts against the locking plate 32 when the locking member 3 is in the unlocked state. Specifically, when the locking member 3 is switched from the locked state to the unlocked state, the driving member drives the driving plate 31 to rotate, causing the locking plate 32 to rotate in the opposite direction to approach the first guide member 21 until it is parallel to the first guide member 21. The blocking plate 6 can prevent the locking plate 32 from continuing to rotate, and the blocking plate 6 abuts against the locking plate 32 to keep the locking member 3 in the unlocked state. Here, by setting the blocking plate 6, the position of the locking plate 32 can be limited to prevent the locking plate 32 from rotating excessively.

[0060] Furthermore, at least two first guide members 21 are provided, and along the length of the cable, the first guide members 21 are located at both ends of the frame 1. Thus, during the movement of the overhead cable 4 relative to the connecting frame 7, at least two first guide members 21 will simultaneously contact the overhead cable 4, thereby improving the stability of the overhead cable 4 and the connecting frame 2 during relative movement. Correspondingly, each first guide member 21 is provided with a locking member 3 and a driving member. The locking of the overhead cable 4 and the connecting frame 7 by the locking members 3 at multiple locations further improves the stability of the docking assembly and the overhead cable 4 during docking.

[0061] like Figure 4As shown, the docking frame 2 also includes a second guide 23 disposed below the first guide 21. The second guide 23 includes a third end 231 located outside the side opening and a fourth end 232 located in the accommodating space. The fourth end 232 is higher than the third end 231. Furthermore, the tilt angles of the upper first guide 21 and the lower second guide 23 are the same. In this way, by setting the first guide 21 and the second guide 23, the first opening becomes a flared mouth, thereby providing a larger opening for docking the high-altitude cable 4 on the outside of the frame 1, making it easier for the docking assembly to dock with the high-altitude cable 4. On the inside of the frame 1 (i.e., in the accommodating space), there is a smaller opening, which allows for more precise guidance of the high-altitude cable 4 to the docking position with the inspection robot 5, improving the docking success rate of the docking assembly.

[0062] Furthermore, at least two second guide members 23 are provided, and along the length of the cable, the second guide members 23 are located at both ends of the frame 1. Thus, during the movement of the overhead cable 4 relative to the connecting frame 7, at least two second guide members 23 will simultaneously contact the overhead cable 4, thereby improving the stability of the overhead cable 4 and the connecting frame 2 during relative movement. Correspondingly, each second guide member 23 is provided with a locking member 3 and a driving member. The locking of the overhead cable 4 and the connecting frame 7 by the locking members 3 at multiple locations further improves the stability of the docking assembly and the overhead cable 4 during docking.

[0063] In addition, this application embodiment also provides a docking device, including a docking component, a connecting frame 7, and a drone that drives the docking component to fly. This docking component is the docking component mentioned above.

[0064] Since the docking device has the aforementioned docking components, the beneficial effects of the docking device brought about by the docking components are described above and will not be repeated here.

[0065] Specifically, the connecting frame 7 is connected to the frame 1 and located above the frame 1, and is used to connect the aircraft. That is to say, the connecting frame 7 is used to connect the aircraft (such as a drone or a manned helicopter) and the frame 1, so that the entire docking assembly can be driven by the drone to fly to a high altitude. The specific structure of the connecting frame 7 is not limited in this application, and it can have a variety of optional structures, as long as it satisfies the need for a stable connection between the drone and the frame 1.

[0066] Furthermore, this application also provides a cable maintenance device, including an inspection robot 5 and a docking device for connecting and disconnecting the inspection robot 5 from the high-altitude cable 4, which is the docking device mentioned above.

[0067] Since the cable maintenance equipment has the aforementioned docking device, please refer to the above content for the beneficial effects brought by the docking device, which will not be repeated here.
