Description

Technical Field

[0001] The present invention relates to the field of electric power construction safety technology, and in particular to a grounding clamp device based on drone control. Background Art

[0002] During the maintenance work of high-voltage transmission lines, the power supply of the lines at the corresponding positions must be cut off. In order to prevent the workers from suffering accidental electric shock, static electricity or induced electricity, grounding operations (also known as hanging ground wires or installing ground wires) need to be performed on both ends of the working section before construction. Generally, the residual charge, induced electricity or possible accidental electric energy on the line is conducted to the earth by installing grounding clamps, making the working section a reliable equipotential body, preventing electric shock accidents and ensuring the safety of maintenance personnel.

[0003] When installing and removing grounding clamps, a common method is to manually climb the overhead wires to the installation site and then manually install or remove them. This method has problems such as high risks of high-altitude operations and low installation efficiency. Although the operation is strictly carried out in accordance with safety regulations, once an accident occurs, it often leads to serious casualties and equipment damage. In recent years, drone technology has been introduced into the field of power construction and is used to replace some high-risk operations. When drones are used for the installation or removal of grounding clamps, the original grounding clamp structure is difficult to cooperate with drones and cannot complete the specified operations. Although there are currently some dedicated grounding clamps for use under drone operations, these existing grounding clamp structures still have problems such as insufficient clamping reliability and complex release operations, which makes subsequent maintenance operations have a high safety risk. Summary of the Invention

[0004] In order to solve the above-mentioned deficiencies in the prior art, the present invention aims to provide a grounding clamp device based on drone control. The device has an automatic clamping and releasing structure to solve the problem of collaborative operation between the grounding clamp and the drone, and the device has high clamping reliability and simple release operation.

[0005] To achieve the above purpose, the technical solution adopted by the present invention is as follows: a grounding clamp device based on drone control, comprising Shell: The shell is formed with a clamping opening for clamping the wire, and a grounding wire base for connecting the grounding wire is fixed at the lower end of the shell; Clamping mechanism: The clamping mechanism can automatically clamp the wire when the wire is placed in the clamping port; Release mechanism: The release mechanism can release the clamping mechanism from the conductor, allowing the grounding clamp to separate from the conductor; Clamp release pin: Set on the top of the shell, it can be disconnected from the shell after the grounding clamp clamps the wire.

[0006] As a definition: the clamping mechanism includes a clamping arm, a main spring, and a trigger rod, one end of the clamping arm is rotatably connected to the shell, and the other end can be rotated to the clamping mouth to clamp the wire; the main spring is located in the vertically arranged shell, the upper end of the main spring is fixedly connected to the upper spring seat, and the upper spring seat is rotatably connected to the middle of the clamping arm through a horizontally arranged first spring shaft; the lower end of the main spring is fixedly connected to the lower spring seat, and the lower spring seat can be movably clamped on the spring clamping seat rotatably arranged on the shell; one end of the trigger rod is rotatably connected to the shell, and the other end extends to the clamping mouth and is located above the clamping arm, and a first pin limiting structure for limiting the position of the clamping arm is provided between the trigger rod and the clamping arm. The trigger rod is touched by the wire at the clamping mouth and rotates upward, so that the first pin limiting structure is opened, so that the clamping arm rotates under the upward elastic force of the main spring to clamp the wire.

[0007] As a limitation: the first pin limiting structure includes a first pin, a first slot and a first torsion spring, the first pin is horizontally fixed on the clamping arm, a first slot matching the first pin is opened on the trigger rod, and the first torsion spring is arranged on the rotating shaft connecting the trigger rod and the shell, and the first torsion spring can provide the trigger rod with a torque for rotating around the rotating shaft and enabling the first pin to be clamped in the first slot.

[0008] As a limitation: a horizontally arranged second spring shaft is passed through the lower spring seat, two ends of the second spring shaft extend out of the lower spring seat, a vertical slide groove is opened on the shell, and two ends of the second spring shaft are slidably arranged in the slide groove.

[0009] As a limitation: one end of the spring clamp is rotatably set on the shell, and a second clamping slot is opened on the spring clamp for movably clamping and limiting the lower end of the main spring. The second spring rotating shaft also serves as a second clamping pin, and the second clamping pin matches the second clamping slot; a second torsion spring is provided at the rotating connection between the spring clamp and the shell, and the second torsion spring can provide the spring clamp with torque for rotating around the rotating shaft and enabling the second clamping slot to clamp the main second clamping pin.

[0010] As a limitation: both ends of the second spring shaft extend out of the housing and are respectively fixed with a reset push handle for resetting the main spring; a reset rotating handle for resetting the first bayonet limiting structure is fixed on the outer side of the clamping arm.

[0011] As a limitation: a telescopic polished rod is provided between the upper spring seat and the lower spring seat, and the two ends of the telescopic polished rod are respectively fixedly connected to the upper spring seat and the lower spring seat and extend and retract along with the length of the main spring.

[0012] As a definition: the release mechanism includes a release handle, a release rod, a release block, and a tension spring. The release handle is located above the top of the shell, the lower end of the release handle passes through the shell and is fixedly connected to the upper end of the release rod vertically arranged in the shell, the lower end of the release rod is fixedly connected to the release block, and the lower end of the release block is connected to the bottom of the shell through a tension spring; the free end of the spring clamp is located above the release block and there is a safety distance between the release block. When the release handle is pulled upward, the release rod and the release block can be driven to move upward until the release block abuts against the spring clamp upward to cause the spring clamp to rotate.

[0013] As a limitation: the clamping release pin is movably arranged on the top of the shell, and its upper end is used to connect with the sling of the drone; a stop block is fixed above the rotating shaft where the clamping arm is rotatably connected to the shell, and the stop block and the clamping arm rotate around the rotating shaft at the same time; when the clamping arm is in the initial state, the card slot provided at the free end of the stop block is clamped on the clamping release pin and the release rod, and the clamping release pin and the release rod cannot move up and down; when the clamping arm clamps the wire, the free end of the stop block rotates away from the clamping release pin and the release rod, and the clamping release pin is pulled out from above to disengage from the grounding clamp, and the release rod can move up and down when the release handle is pulled upward.

[0014] As a limitation: the release handle includes a release base, and the release base is fixedly connected to a release ring or release claw for hooking with the drone.

[0015] As a limitation: conductive copper sheets are fixedly provided at the point where the clamping opening contacts the wire, at the side where the clamping arm contacts the wire, and on the grounding wire base.

[0016] As a limitation: a guide plate is fixedly provided at the end of the clamping opening, which is at a certain angle to the vertical direction and extends outward relative to the clamping opening.

The limit switch is fixed at the clamping mouth to detect the state of the wire in the clamping mouth, and the wireless communication unit is used to transmit signal data.

[0018] Due to the adoption of the above technical solution, the present invention has the following beneficial effects compared with the prior art: (1) The trigger rod in the clamping mechanism limits the initial state of the clamping arm through the first bayonet limit structure. When the wire generates an upward thrust on the trigger rod and rotates clockwise, the limiting effect of the first bayonet limit structure on the clamping arm is released. The upper end of the main spring is released and pushes the clamping arm to clamp the wire. The entire clamping process is very simple and the clamping structure is stable and effective.

[0019] (2) When releasing (removing) the grounding clamp, the release block is driven upward by pulling the release handle and abuts against and pushes the spring holder to rotate upward, so that the second slot loses its limiting effect on the second latch pin, and the lower end of the main spring is released and immediately returns to its original length. At this time, the clamping arm connected to the upper end of the main spring loses the upward pressure of the main spring in the compressed state, and the clamping arm returns to its initial position, achieving the purpose of quickly removing the grounding clamp from the wire.

[0020] (3) The clamping release pin can automatically detach from the shell after the grounding clamp clamps the wire. This design method can realize the function of hooking and lifting the grounding clamp by the drone. On the other hand, since the clamping release pin has an automatic detachment design, the drone and the grounding clamp can be quickly separated after the installation is completed.

[0021] (4) After one use, the present invention can restore the main spring, clamping arm, trigger rod and other components to their initial state to prepare for the next use, and the operation is convenient and fast.

[0022] (5) The present invention is also provided with an intelligent detection module, which can monitor and provide feedback on the status of the grounding clamp in real time. Through remote control by a drone, the device is made more automated and intelligent, and the safety performance is further improved.

[0023] In summary, the clamping mechanism of the present invention automatically clamps the conductor when placed on it by a drone. To release it, the drone simply pulls up on the release ring or claw to release the clamp. Both the clamping and release processes can be coordinated with the drone, and after use, the clamping and release mechanisms are quickly restored to their initial states, ready for the next use. The present invention boasts high clamping reliability and simple release operation, making it suitable for maintenance of high-voltage transmission lines. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0026] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention and do not constitute a limitation of the present invention.

[0027] The directional terms such as "clockwise" and "counterclockwise" or other terms indicating positional relationships described in the present invention are based on the directional relationships in the drawings of the present invention specification and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the content protected by the present invention. Example

[0028] like Figures 1 to 6 The figure shows a grounding clamp device for drone control. It includes an inverted J-shaped housing 1, which consists of a vertical portion and a curved portion. The curved portion forms a downward-opening clamping opening 2. The grounding clamp is equipped with a clamping mechanism and a release mechanism. The clamping mechanism automatically clamps the conductor within the clamping opening 2, and the release mechanism allows the grounding clamp to be removed from the conductor. A grounding wire base 4 is fixed to the lower end of the housing 1 for connecting to a grounding wire 5.

[0029] like Figure 2 、 Figure 3As shown, the mechanism for clamping and fixing the wire is a clamping mechanism, which includes a clamping arm 6, a main spring 7, and a trigger rod 8. One end of the clamping arm 6 is rotatably connected to the housing 1, and the other end can be rotated to the clamping port 2 to clamp the wire; the main spring 7 is located in the vertical part of the housing 1, and the upper end of the main spring 7 is fixedly connected to an upper spring seat 9, and the upper spring seat 9 is rotatably connected to the middle part of the clamping arm 6 through a horizontally arranged first spring shaft 11; the main spring 7 is compressed, and the lower end of the main spring 7 is fixedly connected to a lower spring seat 10 that is movably clamped on a spring clamping seat 12; a telescopic light rod is provided between the upper spring seat 9 and the lower spring seat 10, and the two ends of the telescopic light rod are respectively fixedly connected to the upper spring seat 9 and the lower spring seat 10 and extend and retract with the length of the main spring. A horizontally disposed second spring shaft 15 extends through the lower spring seat 10. Both ends of the second spring shaft 15 extend beyond the lower spring seat 10. Vertical guide slots 25 are defined in the housing 1. Bearings allow the two ends of the second spring shaft 15 to move up and down within the guide slots 25. The second spring shaft 15 extends beyond the lower spring seat 10 and is provided with reset handles 17 for resetting the main spring 7.

[0030] One end of the trigger rod 8 is rotatably connected to the housing 1, and the other end extends to the clamping opening 2 and is located above the clamping arm 6. A first bayonet limiting structure is provided between the trigger rod 8 and the clamping arm 6 for limiting the initial position of the clamping arm 6. When the trigger rod 8 is triggered by the wire at the clamping opening 2 and rotates, the first bayonet limiting structure is opened, causing the clamping arm 6 to rotate under the upward elastic force of the main spring 7, thereby clamping the wire, forming a position as shown in FIG. Figure 3 Status shown in .

[0031] like Figure 4 、 Figure 5 As shown, the first bayonet retaining structure includes a first bayonet 13, a first retaining slot 14, and a first torsion spring (not shown). The first bayonet 13 is horizontally fixed to the clamping arm 6. The trigger lever 8 is provided with a first retaining slot 14 that matches the first bayonet 13. The first torsion spring is disposed on the rotation axis that rotatably connects the trigger lever 8 to the housing 1. The first torsion spring provides the torsional force that enables the trigger lever 8 to rotate counterclockwise about the rotation axis and to engage the first retaining slot 14 with the first bayonet 13. The present invention utilizes the first bayonet retaining structure to constrain the initial state of the clamping arm 6. When the trigger lever 8 rotates clockwise under the upward thrust exerted by the conductor, the first bayonet 13 disengages from the first retaining slot 14, releasing the restraining effect of the first bayonet retaining structure on the clamping arm 6. The upper end of the main spring 7 is released, and the clamping arm 6, propelled by the spring, lifts upward to clamp the conductor. This makes the entire clamping process simple and effective. A reset rotating handle 18 is fixedly provided on the outer side of the clamping arm 6 for resetting the first bayonet limiting structure. By rotating the reset rotating handle 18 , the first bayonet 13 can be re-engaged in the first bayonet groove 14 .

[0032] like Figure 4 、 Figure 6 As shown, one end of the spring retainer 12 is rotatably mounted on the housing 1. A second retaining slot 16 is defined in the spring retainer 12 for movably retaining and restraining the lower end of the main spring 7. The second spring shaft 15 also serves as a second retaining pin, which mates with the second retaining slot 16. A second torsion spring (not shown) is provided at the pivotal connection between the spring retainer 12 and the housing 1. This second torsion spring provides the torsional force required for the spring retainer 12 to rotate counterclockwise about the shaft and engage the second retaining pin in the second retaining slot 16.

[0033] The release mechanism can release the clamping and fixing effect of the clamping mechanism on the wire, so that the grounding clamp is detached and released from the wire. Specifically, the release mechanism includes a release handle, a release rod 21, a release block 22, and a tension spring 23. The release handle is arranged on the top of the shell 1, and the release handle includes a release base 20. The release base 20 is fixedly connected to a release ring 19 or a release claw for hooking with a drone. The release handle is to facilitate the drone to disassemble and release the grounding clamp for hooking. Specifically, the drone uses the sling or hook below it to pull the grounding clamp upward. The specific shape of the release handle is not limited, as long as it is convenient for the sling to hook. This embodiment adopts a circular release ring 19 structure. Of course, a claw-shaped release structure or other structures in the prior art that are convenient for hooking can also be used. The lower end of the release handle passes through the housing 1 and is fixedly connected to the upper end of a release rod 21 vertically disposed within the housing 1. The lower end of the release rod 21 is fixedly connected to a release block 22, the lower end of which is connected to the bottom of the housing 1 via a tension spring 23. The free end of the spring retainer 12 is located above the release block 22 and at a safe distance therefrom. Pulling the release handle upward drives the release rod 21 and release block 22 upward until the release block 22 abuts upward and forces the spring retainer 12 to rotate clockwise. Specifically, in the initial, unused state of the grounding clamp, the lower end of the main spring 7 is compressed within the second retaining groove 16. When the spring retainer 12 is lifted by the release block 22 and rotates clockwise, the restraining effect of the second retaining groove 16 on the lower end of the main spring 7 is released, leaving sufficient space below the main spring 7 for it to return to its original length (i.e., free of elastic force). Consequently, the clamping arm 6 at the upper end of the main spring 7 is no longer subjected to the upward thrust, allowing it to rotate counterclockwise, releasing its grip on the wire. At this time, the grounding clamp can be removed from the conductor to complete the release of the grounding clamp from the conductor.

[0034] A clamping release pin 3 is also provided on the top of the housing 1. On one hand, the clamping release pin 3 can connect the grounding clamp to the sling or hook structure under the drone and lift the grounding clamp to a high altitude. On the other hand, the clamping release pin 3 can be detached from the housing 1 after the grounding clamp completes the wire clamping operation. Then, when the drone is controlled to leave, the clamping release pin 3 also leaves with the drone. In other words, the clamping release pin 3 is movably provided on the top of the housing 1. Specifically, Figure 4As shown, a stopper 24 is provided above the rotation axis through which the clamping arm 6 is rotatably connected to the housing 1. The stopper 24 rotates about the rotation axis simultaneously with the clamping arm 6. In the initial state of the clamping arm 6, the slot provided at the free end of the stopper 24 engages the clamping release pin 3, preventing the clamping release pin 3 from moving up or down. When the clamping arm 6 clamps the conductor, the free end of the stopper 24 rotates clockwise and away from the clamping release pin 3, freeing the lower end of the clamping release pin 3 from restraint and allowing it to be pulled out from above to disengage the grounding clamp. Furthermore, the provision of the stopper 24 prevents the release rod 21 from being accidentally pulled up. Specifically, in the initial state of the clamping arm 6, the slot provided at the free end of the stopper 24 engages the release rod 21, preventing the release rod 21 from moving up or down. When the clamping arm 6 completes clamping the conductor, the free end of the stopper 24 simultaneously rotates away from the release rod 21, allowing the release rod 21 to move up or down when the release handle is pulled upward.

[0035] The grounding clamp's grounding function is achieved by contacting the conductor with the ground. In this embodiment, conductive copper sheets 26 are fixed to the clamping opening 2 where it abuts the conductor, the surface of the clamping arm 6 where it abuts the conductor, and the grounding base 4. Connecting copper wires are provided within the housing 1. This arrangement allows the grounding wire 5 connected to the grounding base 4 to connect to the conductor via the copper sheets and the connecting copper wires.

[0036] A guide plate 27 is fixedly provided at the end of the clamping opening 2 , which is at a certain angle to the vertical direction and extends outward relative to the clamping opening 2 . The guide plate 27 guides the insertion of the wire by increasing the opening of the clamping opening 2 .

[0037] like Figure 2 As shown, the present invention also includes an intelligent detection module 28, which includes a communicatively connected limit switch 29 and a wireless communication unit (not shown). The limit switch 29 is a microswitch with a downwardly fixed spring at the clamping opening 2 for detecting the state of the wire in the clamping opening 2. The wireless communication unit is used to transmit signal data. The intelligent detection module 28 can be implemented using existing technology. The structures of the intelligent detection module 28, limit switch 29, and wireless communication unit are all existing technology.

[0038] The present invention is used as follows: a grounding clamp, set in its initial state and connected to a grounding wire 5, is hooked to a sling below a drone via a clamp release pin 3. The drone is then operated to lift the grounding clamp above the overhead wire. Under the guidance of the guide plate 27, the clamp's clamping opening 2 is lowered toward the wire until it enters the clamping opening 2. When the wire touches the trigger lever 8, which exerts an upward thrust on the trigger lever 8, the trigger lever 8 rotates slightly clockwise and lifts, disengaging the first latching mechanism. This releases the restraint on the clamping arm 6, releasing the upper end of the main spring 7. Under the upward force of the main spring 7, the clamping arm 6 rotates clockwise, clamping the wire. The wire is now clamped in the clamping opening 2, and the spring of the limit switch 29 is compressed, sending a signal to the intelligent detection module 28. While the clamping arm 6 is clamping the wire, the intelligent detection module 28 monitors and provides real-time feedback on the grounding clamp's status.

[0039] After the maintenance work is completed, when the grounding clamp needs to be disassembled and released, the drone is controlled to fly above the grounding clamp, and the release handle (release ring 19 or release claw) fixed at the upper end of the grounding clamp is hooked on the sling below the drone, and the release handle is pulled upward, thereby driving the release rod 21 and the release block 22 to move upward, and finally the second slot 16 loses its limiting effect on the second pin, and the lower end of the main spring 7 is released and restores its original length. Subsequently, the clamping arm 6 also returns to its initial position, and the grounding clamp can be removed from the wire.

[0040] The grounding clamp is manually restored to its initial state: first, the clamp release pin 3 is placed and inserted into its original position, and the reset handle 18 is lifted upward and rotated counterclockwise. This causes the clamping arm 6 to rotate until the stopper 26 fixed to the clamping arm 6 rotates to its initial state. At this point, the stopper 26 re-positions the clamp release pin 3 and the release lever 21, and the first latching pin 13 of the clamping arm 6 is engaged in the first engaging groove 14 defined in the trigger lever 8. Next, the reset push handle 17 is pushed upward along the slide groove 25 to compress the main spring until the reset push handle 17 drives the second spring shaft 15 to re-engage in the second engaging groove 16 of the spring retainer 12. At this point, all mechanisms are reset, and the grounding clamp is restored to its initial state, ready for the next use.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present disclosure, rather than to limit them.
