Technical Field
[0001] This invention relates to the field of power equipment technology, and in particular to a grounding terminal device for high-altitude installation of unmanned aerial vehicles (UAVs). Background Technology
[0002] Currently, when a power line needs maintenance or construction work, a grounding wire must be installed; the grounding wire is considered the lifeline of power workers. In routine power outage maintenance, the grounding work involves an electrician on the tower carrying a pass-through rope. Near a suitable work location, the electrician uses the rope to pass a voltage tester to the tower, where they test each phase one by one. Once they confirm there is no voltage on the line, they lower the tester to the ground and then hoist the grounding wire back up to the tower. A ground electrician then installs the grounding wire on the out-of-power line. This traditional method requires one person to supervise, one person on the tower to perform voltage testing and grounding, and one person on the ground to assist with the transfer work. The grounding wire is heavy and the installation is cumbersome. When ultra-high voltage transmission lines need to be shut down for maintenance or construction work, the grounding wire is generally hung between the transmission line and the tower, and grounding is achieved through the tower.
[0003] With the development of drone applications in the power industry, drones have become an important tool for the operation and maintenance of power transmission and distribution lines. During the maintenance of power transmission and distribution lines, drones are also used to suspend grounding clamps onto power transmission and distribution lines or towers for grounding wire connection. Existing grounding clamps generally have drawbacks such as complex structure and poor reliability.
[0004] Therefore, how to improve the existing grounding clamps to overcome the above-mentioned shortcomings is a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention
[0005] One objective of this invention is to provide a grounding terminal device for high-altitude installation of drones that is easy to operate, has a high success rate of installation, and provides reliable clamping.
[0006] To achieve the above objectives, the technical solution adopted by this invention is: a grounding terminal device installed at a high altitude on a UAV, comprising:
[0007] The hook body is suitable for hanging on a conductive body;
[0008] The limit component is movably mounted on the hook body and has a locked state and an unlocked state.
[0009] The locking hook assembly is movably mounted on the hook body. The movement of the locking hook assembly causes the limit assembly to change from the unlocked state to the locked state.
[0010] The release component is movably mounted on the hook body. The action of the release component causes the limit component to change from the locked state to the unlocked state.
[0011] A lifting hook is provided on the hook body;
[0012] The release hook is located on the release assembly;
[0013] During installation, the drone is suitable for grabbing the lifting hook and suspending the grounding device. The drone's flight causes the hook body to be attached to the conductor. At the same time, the conductor triggers the locking hook assembly, causing the limiting component to change from the unlocked state to the locked state, thereby preventing the hook body from detaching from the conductor. During detachment, the drone is suitable for grabbing the release hook and suspending it from the grounding device. The drone's flight causes the release hook to move, and at the same time, the release hook triggers the release component, causing the limiting component to change from the locked state to the unlocked state. The drone continues to fly, causing the hook body to detach from the conductor.
[0014] Furthermore, the limiting component includes a locking head, a sliding buckle, and a first elastic element. The hook body has a sliding groove with a vertical section and an outward inclined section. The locking head and the sliding buckle are respectively connected to the two ends of the first elastic element, and the locking head and the sliding buckle are slidably disposed in the sliding groove.
[0015] During the installation process, the limiting component is initially in the unlocked state. At this time, the locking hook component restricts the sliding of the card head and keeps the card head in the outer inclined section. The unhooking component restricts the sliding of the sliding buckle and keeps the sliding buckle in the upper part of the vertical section. The first elastic element is in the stretched state. When the conductor triggers the locking hook component to act and releases the restriction on the card head, the card head slides upward under the action of the first elastic element and enters the vertical section from the outer inclined section, so that the limiting component is in the locked state.
[0016] During the disengagement process, the limiting component is initially in a locked state. When the disengagement hook triggers the disengagement component to act and releases the restriction on the sliding buckle, the limiting component slides downward under the action of gravity until the locking head enters the outer inclined section, thus putting the limiting component into the unlocked state.
[0017] Furthermore, the locking head extends into a positioning rod, and the locking hook assembly includes a trigger plate, a multi-link rod, a locking rod, and a locking tongue, which are respectively movably mounted on the hook body and connected in sequence.
[0018] When the limiting component is in the locked state, the locking tongue abuts against the positioning rod and restricts the upward sliding of the locking head, and the locking rod abuts against the locking tongue and restricts the movement of the locking tongue; when the hook body is hung on the conductor, the conductor triggers the trigger plate to move, and the trigger plate drives the locking rod to move through the multi-link rod, thereby releasing the restriction on the locking tongue, and then the locking tongue releases the restriction on the locking head.
[0019] Furthermore, the middle section of the trigger plate is hinged to the hook body, and the front section of the trigger plate extends into the hook body. The multi-link assembly includes a first link, a second link, a third link, and a lever seat. The locking lever is fixedly mounted on the lever seat. The middle section of the locking tongue is hinged to the hook body. The front section of the locking tongue is adapted to abut against the positioning lever, and the locking lever is adapted to move in and out of the rear section of the locking tongue. The hook body is provided with a hinge seat and a telescopic seat. The middle section of the second link is hinged to the hinge seat. The locking lever is slidably mounted on the telescopic seat in the vertical direction. The two ends of the first link are respectively hinged to the rear end of the trigger plate and the upper end of the second link. The two ends of the third link are respectively hinged to the lower end of the second link and the upper end of the lever seat.
[0020] Furthermore, a hanging rod is provided at the upper end of the sliding buckle, and the release component includes a linkage, a pull hook and a second elastic element. The release hook is slidably mounted on the hook body in the vertical direction. The lower end of the release hook is connected to the linkage, and the upper end of the pull hook is connected to the linkage. The second elastic element forces the release hook to slide downward. At this time, the lower end of the pull hook is connected to the hanging rod and restricts the sliding buckle from sliding downward.
[0021] During the release process, the drone grabs the release hook and forces it to slide upward against the elastic force of the second elastic element. The release hook then drives the pull hook to move through the linkage, thereby detaching from the hanging rod, and the release hook assembly releases the restriction on the sliding buckle.
[0022] Furthermore, the linkage includes a slider and a fourth link. The slider is slidably mounted on the hook body in the vertical direction. The disengagement hook is connected to the upper end of the slider. The middle section of the hook is hinged to the hook body. The two ends of the fourth link are respectively hinged to the lower end of the slider and the upper end of the hook. The lower end of the hook is suitable for connecting the hanging rod. The second elastic element is sleeved on the disengagement hook and located between the slider and the hook body.
[0023] Furthermore, the card head includes a sliding section, an extension section, and a hook section. The sliding section is adapted to be slidably disposed in the groove. The extension section passes through the hook body and extends into the hook body. In the locked state, the hook section extends obliquely upward and is adapted to cooperate with the hook body to restrict the conductor from detaching.
[0024] Furthermore, the hook body is U-shaped, and a mounting base is formed on one side of the hook body. The limiting component, locking hook component, unhooking component and unhooking hook are movably mounted on the mounting base, and the lifting hook is fixedly mounted on the mounting base.
[0025] An adjustment assembly is also provided on the other side of the hook body. The adjustment assembly includes an adjustment ring and a third elastic element. The adjustment ring is rotatably mounted on the hook body, and the third elastic element is located between the adjustment ring and the hook body and forces the adjustment ring to move closer to the hook body. When the hook body is hung on a conductor, the adjustment ring is adapted to press against the conductor through the deformation of the third elastic element.
[0026] Furthermore, the adjusting ring includes a guide section and a clamping section. The lower end of the guide section is rotatably mounted on the other side of the hook body. The upper end of the guide section is connected to the lower end of the clamping section. The upper end of the clamping section is connected to one end of the third elastic element, and the other end of the third elastic element is connected to the other side of the hook body. The guide section is inclined from top to bottom from one side of the hook body to the other side, and the clamping section is inclined from top to bottom from the other side of the hook body to one side. When the hook body is hung on the conductor, the conductor passes over the guide section and is clamped by the clamping section.
[0027] Furthermore, a guide plate is provided at the lower end of the other side of the hook body, and the conductor is adapted to enter the hook body along the guide plate;
[0028] A protective plate is also provided between the lower end of one side of the hook body and the lower end of the lifting hook. The hook body, the lifting hook and the protective plate form a closed frame; the limiting component, the locking component and the unhooking component are located inside the closed frame.
[0029] Compared with existing technologies, the advantages of this invention are as follows: During the installation process, the grounding device of this solution automatically switches the limiting component from the unlocked state to the locked state by the action of the hook assembly, requiring no additional operation. When detachment is needed, the drone only needs to pull up the release hook (which serves as both the attachment point and the unlocking switch) to automatically unlock, again requiring no additional operation. More importantly, due to the special structure of the hook assembly, the grounding device can only be activated after the grounding device is properly installed, preventing accidental activation and ensuring a high success rate for installation. Furthermore, the special structure of the limiting component ensures reliable clamping. Moreover, when detachment is needed, the release component can only be activated after the drone pulls up the release hook, again preventing accidental activation, thus ensuring both reliable clamping and ease of detachment.

[0043] The present invention will now be further described in conjunction with specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.
[0044] In the description of this invention, it should be noted that directional terms such as "center," "lateral," "longitudinal," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise" indicate the orientation and positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. They should not be construed as limiting the specific protection scope of this invention.
[0045] It should be noted that the terms "first," "second," etc., in the specification and claims of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.
[0046] like Figures 1 to 12 As shown, a preferred embodiment of the present invention includes:
[0047] The hook body 1 is suitable for hanging on the angle steel 200 of the iron tower; in this embodiment, the hook body 1 is U-shaped, and a mounting base 11 is formed on one side of the hook body 1.
[0048] Limiting component 2 is movably mounted on mounting base 11 and has a locked state and an unlocked state.
[0049] The locking hook assembly 3 is movably mounted on the mounting base 11. The action of the locking hook assembly 3 causes the limit assembly 2 to change from the unlocked state to the locked state.
[0050] The release component 4 is movably mounted on the mounting base 11. The action of the release component 4 causes the limit component 2 to change from the locked state to the unlocked state.
[0051] Lifting hook 5 is fixedly mounted on mounting base 11.
[0052] Release hook 6 is set on release assembly 4.
[0053] Adjustment component 7 is movably set on the other side of hook body 1, and plays a guiding, positioning and auxiliary clamping role.
[0054] Guide plate 8 is fixedly installed at the lower end of the other side of hook body 1. Iron tower angle steel 200 is suitable to enter hook body 1 along guide plate 8 and play a guiding role.
[0055] The protective plate 9 is located between the lower end of one side of the hook body 1 and the lower end of the lifting hook 5. The hook body 1, the lifting hook 5 and the protective plate 9 form a closed frame. The limiting component 2, the locking component 3 and the unhooking component 4 are located within the closed frame, which play a protective role and prevent accidental triggering.
[0056] Its basic working principle is as follows: During the installation process, the drone 100 is adapted to grab the lifting hook 5 to hang the grounding end device. The flight of the drone 100 causes the hook body 1 to be hung on the tower angle steel 200. At the same time, the tower angle steel 200 triggers the locking hook assembly 3 to act, causing the limiting assembly 2 to change from the unlocked state to the locked state, thereby preventing the hook body 1 from detaching from the tower angle steel 200. During the detachment process, the drone 100 is adapted to grab the release hook 6 to lift away from the grounding end device. The flight of the drone 100 causes the release hook 6 to move. At the same time, the release hook 6 triggers the release assembly 4 to act, causing the limiting assembly 2 to change from the locked state to the unlocked state. Then, the drone 100 continues to fly, causing the hook body 1 to detach from the tower angle steel 200.
[0057] It should be noted that the hanging process of the present invention refers to the process in which the UAV 100 hooks the grounding device and lifts it from the ground to the air and then hangs it on the iron tower angle steel 200; the detachment process of the present invention refers to the process in which the UAV 100 hooks the grounding device in the air and lifts it away from the iron tower angle steel 200 and then returns to the ground.
[0058] More specifically, such as Figure 5 , Figure 7 and Figure 11 As shown, the limiting component 2 includes a locking head 21, a sliding buckle 22, and a first elastic member 23. A sliding groove 12 is provided on the mounting base 11, the sliding groove 12 having a vertical section 121 and an outwardly inclined section 122. The first elastic member 23 is connected at both ends to the locking head 21 and the sliding buckle 22, respectively, and the locking head 21 and the sliding buckle 22 are slidably disposed within the sliding groove 12. Figure 5 , Figure 7 and Figure 10 As shown, a hanging rod 221 is provided at the upper end of the sliding buckle 22. The release assembly 4 includes a linkage 41, a pull hook 42, and a second elastic element 43. The release hook 6 is slidably mounted on the mounting base 11 in the vertical direction. The lower end of the release hook 6 is connected to the linkage 41, and the upper end of the pull hook 42 is also connected to the linkage 41. The second elastic element 43 forces the release hook 6 to slide downward. At this time, the lower end of the pull hook 42 is connected to the hanging rod 221 and restricts the sliding buckle 22 from sliding downward. Its specific working principle is as follows:
[0059] Installation process: The UAV 100 is suitable for grabbing the lifting hook 5 and suspending the grounding terminal device, such as... Figure 5 and Figure 6As shown, at this time, the limiting component 2 is first in the unlocked state, the locking hook component 3 restricts the sliding of the locking head 21 and makes the locking head 21 located on the outer inclined section 122, the unhooking component 4 restricts the sliding of the sliding buckle 22 and makes the sliding buckle 22 located at the upper end of the vertical section 121, and the first elastic element 23 is in the stretched state. When the drone 100 flies, the hook body 1 is hung on the iron tower angle steel 200, as shown. Figure 7 and Figure 8 As shown, when the tower angle steel 200 triggers the locking hook assembly 3 to act and releases the restriction on the clamp head 21, the clamp head 21 slides upward under the action of the first elastic member 23 and enters the vertical section 121 from the outer inclined section 122, so that the limiting assembly 2 is in a locked state, thereby restricting the hook body 1 from detaching from the tower angle steel 200.
[0060] Release process: The UAV 100 is suitable for grabbing the release hook 6 and lifting it off the grounding device, such as... Figure 7 and Figure 8 As shown, the limit component 2 is initially in a locked state, as... Figure 10 As shown, when the drone 100 flies, it causes the release hook 6 to move, forcing the release hook 6 to slide upward against the elastic force of the second elastic element 43. The release hook 6 drives the pull hook 42 to move through the linkage 41, thereby disengaging from the hanging rod 221. In turn, the release hook assembly 4 releases the restriction on the sliding buckle 22, as shown. Figure 11 As shown, the limiting component 2 slides downward under the action of gravity until the locking head 21 enters the outer inclined section 122, so that the limiting component 2 is in the unlocked state, and then the drone 100 continues to fly, causing the hook body 1 to detach from the iron tower angle steel 200.
[0061] In this embodiment, the locking hook assembly 3 adopts a multi-link locking structure, such as Figures 5 to 8As shown, the locking head 21 extends into a positioning rod 211. The locking hook assembly 3 includes a trigger plate 31, a multi-link rod 32, a locking rod 33, and a locking tongue 34, which are movably mounted on the hook body 1 and connected in sequence. When the limiting assembly 2 is in the locked state, the locking tongue 34 abuts against the positioning rod 211 and restricts the locking head 21 from sliding upward. The locking rod 33 abuts against the locking tongue 34 and restricts the movement of the locking tongue 34. When the hook body 1 is hung on the tower angle steel 200, the tower angle steel 200 triggers the trigger plate 31 to move. The trigger plate 31 drives the locking rod 33 to move through the multi-link rod 32, thereby releasing the restriction on the locking tongue 34. In turn, the locking tongue 34 releases the restriction on the locking head 21. More specifically, the trigger plate 31 is hinged to the hook body 1 in the middle section, and the front section of the trigger plate 31 extends into the hook body 1. The multi-link 32 includes a first link 321, a second link 322, a third link 323, and a rod seat 324. The locking rod 33 is fixedly mounted on the rod seat 324. The locking tongue 34 is hinged to the mounting base 11 in the middle section. The front section of the locking tongue 34 is adapted to abut against the positioning rod 211. The locking rod 33 is adapted to move in and out of the rear section of the locking tongue 34. The mounting base 11 is provided with a hinge seat 13 and a telescopic seat 14. The second link 322 is hinged to the hinge seat 13 in the middle section. The locking rod 33 is slidably mounted on the telescopic seat 14 in the vertical direction. The two ends of the first link 321 are respectively hinged to the rear end of the trigger plate 31 and the upper end of the second link 322. The two ends of the third link 323 are respectively hinged to the lower end of the second link 322 and the upper end of the rod seat 324.
[0062] Furthermore, such as Figure 10 As shown, the linkage 41 in this embodiment includes a slider 411 and a fourth connecting rod 412. The slider 411 is slidably disposed on the mounting base 11 in the vertical direction. The release hook 6 is connected to the upper end of the slider 411. The middle section of the pull hook 42 is hinged to the mounting base 11. The two ends of the fourth connecting rod 412 are respectively hinged to the lower end of the slider 411 and the upper end of the pull hook 42. The lower end of the pull hook 42 is suitable for connecting to the hanging rod 221. The second elastic member 43 is sleeved on the release hook 6 and located between the slider 411 and the mounting base 11.
[0063] Furthermore, such as Figure 12 As shown, in order to ensure reliable locking, the locking head 21 includes a sliding section 212, an extension section 213 and a hook section 214. The sliding section 212 is adapted to be slidably disposed in the slide groove 12. The extension section 213 passes through the hook body 1 and extends to the inside of the hook body 1. In the locked state, the hook section 214 extends obliquely upward and is adapted to cooperate with the hook body 1 to restrict the tower angle steel 200 from disengaging.
[0064] like Figure 4As shown, the adjustment assembly 7 includes an adjustment ring 71 and a third elastic element 72. The adjustment ring 71 is rotatably mounted on the hook body 1, and the third elastic element 72 is disposed between the adjustment ring 71 and the hook body 1 and forces the adjustment ring 71 to move closer to the hook body 1. When the hook body 1 is hung on the tower angle steel 200, the adjustment ring 71 is adapted to press against the tower angle steel 200 through the deformation of the third elastic element 72. Furthermore, the adjusting ring 71 includes a guide section 711 and a clamping section 712. The lower end of the guide section 711 is rotatably mounted on the other side of the hook body 1. The upper end of the guide section 711 is connected to the lower end of the clamping section 712. The upper end of the clamping section 712 is connected to one end of a third elastic member 72, and the other end of the third elastic member 72 is connected to the other side of the hook body 1. The guide section 711 tilts downwards from one side of the hook body 1 to the other side, and the clamping section 712 tilts downwards from the other side of the hook body 1 to one side. When the hook body 1 is hung on the tower angle steel 200, the tower angle steel 200 passes over the guide section 711 and is clamped by the clamping section 712. Through the above structure, a corner protruding towards one side of the hook body 1 is formed between the guide section 711 and the clamping section 712. The corner restricts the use of the tower angle steel 200, further ensuring the reliability of the clamping.
[0065] As can be seen from the accompanying drawings, the elastic elements in this embodiment are all springs, but other structures or components that can achieve the same function are not excluded.
