Description

Technical Field

[0001] The invention relates to the technical field of electric power equipment, and in particular to a grounding terminal device installed at a high place of an unmanned aerial vehicle. Background Art

[0002] At present, when a line that is out of service needs to be inspected and constructed, a grounding wire needs to be connected. The grounding wire is known as the lifeline of power workers. For daily power outage inspection and maintenance work related to power testing and grounding, the electrician on the tower needs to carry a transfer rope. Near the appropriate working position, the test pen is passed to the tower through the transfer rope. The electrician on the tower will conduct phase-by-phase power testing. After confirming that there is no voltage on the line, the test pen is lowered to the ground, and the grounding wire is hoisted to the tower. The ground electrician will install the grounding wire on the power outage line. This traditional operation method requires one person to monitor, one person on the tower is responsible for power testing and grounding, and one person on the ground cooperates with the transfer work. The grounding wire is heavy and cumbersome to install. When the ultra-high voltage transmission line needs to be shut down for inspection and construction, the grounding wire is generally hung between the transmission line and the tower, and grounded through the tower.

[0003] With the development of drone applications in the power industry, drones have become an important tool for the inspection of power transmission and distribution lines. During the inspection of power transmission and distribution lines, drones are also used to hang grounding wire clamps on transmission and distribution lines or towers for grounding wire hooking. Existing grounding wire clamps generally have disadvantages such as complex structure and poor reliability.

[0004] Therefore, how to improve the existing grounding wire clamp to overcome the above-mentioned shortcomings is a technical problem that needs to be solved urgently by those skilled in the art. Summary of the invention

[0005] One object of the present invention is to provide a grounding terminal device for high-place installation of a drone, which is easy to operate, has a high hanging success rate, and is reliable in clamping.

[0006] In order to achieve the above purpose, the technical solution adopted by the present invention is: a grounding terminal device installed at a high place of a UAV comprises: A hook body, the hook body is suitable for being hung on a conductor; A limit assembly, which is movably arranged on the hook body and has a locked state and an unlocked state; A lock hook assembly, which is movably arranged on the hook body, and the action of the lock hook assembly causes the limit assembly to change from an unlocked state to a locked state; A decoupling assembly, which is movably arranged on the hook body, and the action of the decoupling assembly causes the limit assembly to change from a locked state to an unlocked state; A lifting hook, the lifting hook is arranged on the hook body; A release hook, the release hook is arranged on the release assembly; During the hanging process, the drone is suitable for grabbing the lifting hook and hanging the grounding terminal device. The flight of the drone makes the hook body hung on the conductor. At the same time, the conductor triggers the action of the locking hook assembly, so that the limit assembly changes from the unlocked state to the locked state, thereby limiting the hook body from being separated from the conductor; during the disengagement process, the drone is suitable for grabbing the disengagement hook and lifting it away from the grounding terminal device. The flight of the drone makes the disengagement hook move. At the same time, the disengagement hook triggers the action of the disengagement assembly, so that the limit assembly changes from the locked state to the unlocked state, and then the drone continues to fly so that the hook body is hung and separated from the conductor.

[0007] Furthermore, the limit assembly includes a clamp, a slide buckle and a first elastic member, a slide groove is provided on the hook body, and the slide groove has a vertical section and an outer inclined section; the two ends of the first elastic member are respectively connected to the clamp and the slide buckle, and the clamp and the slide buckle are slidably arranged in the slide groove; During the hanging process, the limit assembly is first in the unlocking state 1, at which time the lock hook assembly restricts the sliding of the clamp head and makes the clamp head located at the outer oblique section, the unhooking assembly restricts the sliding of the slide buckle and makes the slide buckle located at the upper end of the vertical section, and the first elastic member is in a stretched state. When the conductor triggers the lock hook assembly to act and release the restriction on the clamp head, the clamp head slides upward under the action of the first elastic member and enters the vertical section from the outer oblique section, so that the limit assembly is in a locked state; During the disengagement process, the limit assembly is first in a locked state. When the disengagement hook triggers the action of the disengagement assembly and releases the restriction on the slide buckle, the limit assembly slides downward under the action of gravity until the clamping head enters the outer inclined section, so that the limit assembly is in the unlocked state two.

[0008] Furthermore, the clamp head extends out a positioning rod, and the lock hook assembly includes a trigger plate, a multi-link rod, a lock rod and a lock tongue, which are respectively movably arranged on the hook body and connected in sequence; When the limit assembly is in a locked state, the lock tongue abuts against the positioning rod and limits the upward sliding of the clamp head, and the lock rod abuts against the lock tongue and limits the movement of the lock tongue; when the hook body is hung on the conductor, the conductor triggers the trigger plate to move, and the trigger plate drives the lock rod to move through the multi-link rod parts to release the restriction on the lock tongue, and then the lock tongue releases the restriction on the clamp head.

[0009] 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 rod comprises a first connecting rod, a second connecting rod, a third connecting rod and a rod seat. The locking rod is fixedly arranged on the rod seat. The middle section of the lock tongue is hinged to the hook body. The front section of the lock tongue is suitable for contacting the positioning rod, and the locking rod is suitable for entering and exiting the rear section of the lock tongue. A hinge seat and a telescopic seat are arranged on the hook body. The middle section of the second connecting rod is hinged to the hinge seat, and the locking rod is slidably arranged on the telescopic seat in a vertical direction. The two ends of the first connecting rod are respectively hinged to the rear end of the trigger plate and the upper end of the second connecting rod, and the two ends of the third connecting rod are respectively hinged to the lower end of the second connecting rod and the upper end of the rod seat.

[0010] Further, a hanging rod is provided at the upper end of the sliding buckle. The decoupling component includes a linkage member, a hook, and a second elastic member. The decoupling hook is slidably arranged on the hook body in the vertical direction. The lower end of the decoupling hook is connected to the linkage member, the upper end of the hook is connected to the linkage member, and the second elastic member forces the decoupling hook to slide downward. At this time, the lower end of the hook is connected to the hanging rod and restricts the downward sliding of the sliding buckle. During the detachment process, the drone grabs the decoupling hook and forces the decoupling hook to slide upward against the elastic force of the second elastic member. The decoupling hook drives the hook to move through the linkage member to disengage from the hanging rod, and then the decoupling component releases the restriction on the sliding buckle.

[0011] Further, the linkage member includes a slider and a fourth connecting rod. The slider is slidably arranged on the hook body in the vertical direction. The decoupling 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 connecting rod are respectively hinged to the lower end of the slider and the upper end of the hook. The lower end of the hook is adapted to be connected to the hanging rod; the second elastic member is sleeved on the decoupling hook and is located between the slider and the hook body.

[0012] Further, the chuck includes a sliding section, an extending section, and an inclined hook section. The sliding section is adapted to be slidably arranged in the chute. The extending section passes through the hook body and extends towards the inner side of the hook body. In the locked state, the inclined hook section extends obliquely upward and is adapted to cooperate with the hook body to restrict the detachment of the conductor.

[0013] Further, the hook body is in a U-shaped configuration. An installation seat is formed on one side of the hook body. The limiting component, the locking hook component, the decoupling component, and the decoupling hook are movably arranged on the installation seat. The lifting hook is fixedly arranged on the installation seat; On the other side of the hook body, an adjusting component is further provided. The adjusting component includes an adjusting ring and a third elastic member. The adjusting ring is rotatably arranged on the hook body. The third elastic member is arranged between the adjusting ring and the hook body and forces the adjusting ring to approach one side of the hook body; when the hook body is hung on the conductor, the adjusting ring is adapted to press against the conductor through the deformation of the third elastic member.

[0014] Further, the adjusting ring includes a guiding section and a pressing section. The lower end of the guiding section is rotatably arranged on the other side of the hook body. The upper end of the guiding section is connected to the lower end of the pressing section. The upper end of the pressing section is connected to one end of the third elastic member. The other end of the third elastic member is connected to the other side of the hook body; the guiding section is inclined from one side of the hook body to the other side from top to bottom, and the pressing section is inclined from the other side of the hook body to one side from top to bottom. When the hook body is hung on the conductor, the conductor passes over the guiding section and is pressed by the pressing section.

[0015] Further, a guiding plate is further provided at the lower end of the other side of the hook body. The conductor is adapted to enter the hook body along the guiding plate; A protective plate is further provided between the lower ends of one side of the hook body and the lifting hook. The hook body, the lifting hook, and the protective plate form a closed frame; the limiting component, the locking hook component, and the decoupling component are located inside the closed frame.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: the grounding terminal device of the present solution can rely on the action of the lock hook assembly during the hanging process to make the limit assembly automatically change from the unlocked state to the locked state without the need for additional operations; when it is necessary to disengage, the drone only needs to pull up the release hook (the release hook serves as both a hanging point and an unlocking switch) to automatically unlock, also without the need for additional operations. More importantly, due to the special structure of the lock hook assembly of the present solution, the grounding terminal device can only be triggered by the lock hook assembly after it is hung in place, and will not be accidentally triggered, thus ensuring the success rate of hanging; and due to the special structure of the limit assembly, the reliability of its clamping can be guaranteed; further, when it is necessary to disengage, the release hook assembly can only be triggered when the drone pulls up the release hook, and will not be accidentally triggered, thus ensuring both the reliability of clamping and the ease of disengagement.

[0022] like Figures 1 to 12 As shown, a preferred embodiment of the present invention includes: The hook body 1 is suitable for being hung on the tower angle steel 200 ; the hook body 1 of this embodiment is in a U-shape, and a mounting seat 11 is formed on one side of the hook body 1 .

[0023] The limit assembly 2 is movably arranged on the mounting seat 11, and the limit assembly 2 has a locked state and an unlocked state.

[0024] The lock hook assembly 3 is movably arranged on the mounting seat 11 , and the action of the lock hook assembly 3 causes the limit assembly 2 to change from an unlocked state to a locked state.

[0025] The unhooking component 4 is movably arranged on the mounting seat 11 , and the action of the unhooking component 4 causes the limiting component 2 to change from a locked state to an unlocked state.

[0026] The lifting hook 5 is fixedly arranged on the mounting seat 11 .

[0027] The disengagement hook 6 is arranged on the disengagement component 4 .

[0028] The adjusting component 7 is movably arranged on the other side of the hook body 1 to play the role of guiding, positioning and auxiliary clamping.

[0029] The guide plate 8 is fixedly arranged at the lower end of the other side of the hook body 1. The iron tower angle steel 200 is suitable for entering the hook body 1 along the guide plate 8 to play a guiding role.

[0030] The protective plate 9 is arranged 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 limit component 2, the locking hook component 3, and the unhooking component 4 are located in the closed frame to play a protective role and avoid accidental triggering.

[0031] Its basic working principle is as follows: during the hanging process, the drone 100 is suitable for grabbing the lifting hook 5 to hang the grounding terminal device. The flight of the drone 100 makes the hook body 1 hung on the tower angle steel 200. At the same time, the tower angle steel 200 triggers the locking hook component 3 to move, so that the limit component 2 changes from the unlocked state to the locked state, thereby limiting the hook body 1 from being separated from the tower angle steel 200; during the separation process, the drone 100 is suitable for grabbing the disengaging hook 6 to be lifted away from the grounding terminal device. The flight of the drone 100 makes the disengaging hook 6 move. At the same time, the disengaging hook 6 triggers the disengaging hook 4 to move, so that the limit component 2 changes from the locked state to the unlocked state, and then the drone 100 continues to fly so that the hook body 1 is hung and separated from the tower angle steel 200.

[0032] It should be noted that the hanging process of the present invention refers to the process in which the UAV 100 hooks the grounding terminal device and lifts it from the ground to the air and then hangs it on the tower angle steel 200; the detachment process of the present invention refers to the process in which the UAV 100 hooks the grounding terminal device in the air and lifts it from the tower angle steel 200 and then returns to the ground.

[0033] More specifically, Figure 5 , Figure 7 and Fig.11 As shown, the limit assembly 2 includes a clamp head 21, a slide buckle 22 and a first elastic member 23. The mounting seat 11 is provided with a slide slot 12, which has a vertical section 121 and an outer inclined section 122. The two ends of the first elastic member 23 are respectively connected to the clamp head 21 and the slide buckle 22, and the clamp head 21 and the slide buckle 22 are slidably arranged in the slide slot 12. Figure 5 , Figure 7 and Fig.10 As shown, a hanging rod 221 is arranged at the upper end of the slide buckle 22, the unhooking assembly 4 includes a linkage member 41, a hook 42 and a second elastic member 43, the unhooking hook 6 is slidably arranged on the mounting seat 11 along the vertical direction, the lower end of the unhooking hook 6 is connected to the linkage member 41, the upper end of the hook 42 is connected to the linkage member 41, and the second elastic member 43 forces the unhooking hook 6 to slide downward, at which time the lower end of the hook 42 is connected to the hanging rod 221 and restricts the slide buckle 22 from sliding downward. Its specific working principle is as follows: Installation process: The drone 100 is adapted to grab the lifting hook 5 and hang the grounding terminal device, such as Figure 5 and Figure 6 As shown, at this time, the limit assembly 2 is first in the unlocking state 1, the lock hook assembly 3 limits the sliding of the clamp head 21 and makes the clamp head 21 located at the outer inclined section 122, the unhooking assembly 4 limits the sliding of the slide buckle 22 and makes the slide buckle 22 located at the upper end of the vertical section 121, and the first elastic member 23 is in a stretched state. When the drone 100 flies, the hook body 1 is hung on the tower angle steel 200, as shown in FIG. Figure 7 and Figure 8 As shown, when the tower angle steel 200 triggers the locking hook assembly 3 to move and releases the restriction on the clamping head 21, the clamping 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.

[0034] Disengagement process: The drone 100 is adapted to grab the release hook 6 and lift it off the ground terminal device, such as Figure 7 and Figure 8 As shown, at this time, the limit assembly 2 is first in a locked state, such as Fig.10 As shown, when the drone 100 flies, the release hook 6 moves and forces the release hook 6 to overcome the elastic force of the second elastic member 43 and slide upward. The release hook 6 drives the pull hook 42 to move through the linkage member 41 and thus detach from the hanging rod 221, and then the release hook assembly 4 releases the restriction on the slide buckle 22. Fig.11 As shown, the limit assembly 2 slides downward under the action of gravity until the clamping head 21 enters the outer inclined section 122, so that the limit assembly 2 is in the unlocked state 2, and then the drone 100 continues to fly so that the hook body 1 is detached from the tower angle steel 200.

[0035] In this embodiment, the lock hook assembly 3 adopts a multi-link lock structure, such as Figures 5 to 8As shown, the clamping head 21 extends out of the positioning rod 211, and 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 respectively movably arranged on the hook body 1 and connected in sequence; when the limiting assembly 2 is in a locked state, the locking tongue 34 abuts against the positioning rod 211 and restricts the clamping head 21 from sliding upward, and 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 iron tower angle steel 200, the iron tower angle steel 200 triggers the trigger plate 31 to move, and 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, and then the locking tongue 34 releases the restriction on the clamping head 21. More specifically, the middle section of the trigger plate 31 is hinged to the hook body 1, and the front section of the trigger plate 31 extends into the hook body 1. The multi-link rod 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 arranged on the rod seat 324.

The slider 411 is slidably arranged on the mounting seat 11 along the vertical direction. The disengagement hook 6 is connected to the upper end of the slider 411. The middle section of the hook 42 is hinged to the mounting seat 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 hook 42. The lower end of the hook 42 is suitable for connecting to the hanging rod 221. The second elastic member 43 is sleeved on the disengagement hook 6 and is located between the slider 411 and the mounting seat 11.

[0037] Further, such as Fig.12 As shown, in order to ensure reliable locking, the clamping head 21 includes a sliding section 212, an extension section 213 and an oblique hook section 214. The sliding section 212 is suitable for being slidably set in the slide groove 12, and the extension section 213 passes through the hook body 1 and extends toward the inner side of the hook body 1. In the locked state, the oblique hook section 214 extends obliquely upward and is suitable for cooperating with the hook body 1 to limit the detachment of the tower angle steel 200.

[0038] like Figure 4As shown, the adjustment assembly 7 includes an adjustment ring 71 and a third elastic member 72. The adjustment ring 71 is rotatably arranged on the hook body 1. The third elastic member 72 is arranged between the adjustment ring 71 and the hook body 1 and forces the adjustment ring 71 to approach one side of the hook body 1. When the hook body 1 is hung on the tower angle steel 200, the adjustment ring 71 is suitable for pressing against the tower angle steel 200 through the deformation of the third elastic member 72. Further, the adjusting ring 71 includes a guide section 711 and a tightening section 712, the lower end of the guide section 711 is rotatably arranged 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 tightening section 712, the upper end of the tightening section 712 is connected to one end of the 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 is inclined from one side of the hook body 1 to the other side from top to bottom, and the tightening section 712 is inclined from the other side of the hook body 1 to one side from top to bottom. When the hook body 1 is hung on the iron tower angle steel 200, the iron tower angle steel 200 passes over the guide section 711 and is tightened by the tightening section 712. Through the above structure, a corner protruding toward one side of the hook body 1 is formed between the guide section 711 and the tightening section 712, and the corner has a limiting effect on the iron tower angle steel 200, further ensuring the reliability of clamping.
