Description

Technical Field

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

[0002] During the maintenance of high-voltage transmission lines, it is necessary to disconnect the power to the corresponding locations of the lines. In order to prevent workers from suffering accidental electric shock, static electricity, or induced electric shock, grounding operations (also known as hanging grounding wires or installing grounding wires) must be carried out at both ends of the work section before construction. Generally, this is done by installing grounding clamps to conduct residual charge, induced electricity, or any electrical energy that may be accidentally delivered on the line to the ground, making the work section a reliable equipotential body, preventing electric shock accidents, and ensuring the safety of maintenance personnel.

[0003] The common method for installing and removing grounding clamps is to manually climb high-altitude power lines to the installation location, and then manually install or remove them. This method has problems such as high risks associated with working at heights and low installation efficiency. Although safety regulations are strictly followed during operation, accidents often lead to serious personal injury and equipment damage. In recent years, drone technology has been introduced into the field of power construction to replace some high-risk operations. However, when drones are used for the installation or removal of grounding clamps, the existing grounding clamp structure is difficult to coordinate with the drone and cannot complete the prescribed operations. Although there are some dedicated grounding clamps for drone operation, these existing grounding clamp structures still have problems such as insufficient clamping reliability and complex release operations, which pose high safety risks to subsequent maintenance work. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention aims to provide a grounding clamp device based on UAV control. This device has an automatic clamping and releasing structure to solve the problem of collaborative operation between the grounding clamp and the UAV. Furthermore, the device has high clamping reliability and simple release operation.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a grounding clamp device based on UAV control, comprising... Housing: The housing has a clamping opening for holding the wire, and a grounding base for connecting the grounding wire is fixed at the lower end of the housing; Clamping mechanism: The clamping mechanism can automatically clamp the wire when it is placed in the clamping opening; Release mechanism: The release mechanism can release the clamping and fixing effect of the clamping mechanism on the conductor, allowing the grounding clamp to detach from the conductor; Clamping release pin: Located at the top of the housing, it can be detached from the housing after the grounding clamp holds the wire.

[0006] As a limitation: 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 housing, and the other end can rotate to the clamping opening to clamp the wire. The main spring is located in the vertically arranged housing, and the upper end of the main spring is fixedly connected to an upper spring seat. 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 a lower spring seat, which can be movably locked onto a spring holder rotatably arranged on the housing. One end of the trigger rod is rotatably connected to the housing, and the other end extends to the clamping opening and is located above the clamping arm. A first locking pin limiting structure is provided between the trigger rod and the clamping arm to limit the position of the clamping arm. When the trigger rod is touched by the wire at the clamping opening and rotates upward, the first locking pin limiting structure is opened, and the clamping arm rotates under the upward elastic force of the main spring to clamp the wire.

[0007] As a limitation: the first locking pin limiting structure includes a first locking pin, a first locking groove and a first torsion spring. The first locking pin is horizontally fixed on the clamping arm. A first locking groove matching the first locking pin is opened on the trigger rod. The first torsion spring is set on the rotating shaft that rotatably connects the trigger rod and the housing. The first torsion spring can provide the trigger rod with the torque to rotate around the rotating shaft and enable the first locking pin to be locked in the first locking groove.

[0008] As a limitation: a horizontally arranged second spring shaft is provided on the lower spring seat, with both ends of the second spring shaft extending out of the lower spring seat, and vertical grooves are opened on the housing, with both ends of the second spring shaft slidably arranged in the grooves.

[0009] As a limitation: one end of the spring holder is rotatably mounted on the housing, and a second slot is provided on the spring holder for moving and locking and restricting the lower end of the main spring. The second spring shaft also serves as a second locking pin, and the second locking pin matches the second slot. A second torsion spring is provided at the rotatable connection between the spring holder and the housing. The second torsion spring can provide the spring holder with torque to rotate around the shaft and enable the second slot to lock the main second locking pin.

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

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

[0012] As a limitation: 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 housing. The lower end of the release handle passes through the housing and is fixedly connected to the upper end of the release rod, which is vertically installed inside the housing. The lower end of the release rod is fixedly connected to the release block. The lower end of the release block is connected to the bottom of the housing through the tension spring. The free end of the spring holder is located above the release block and there is a safe distance between it and the release block. When the release handle is pulled upward, it can drive the release rod and the release block to move upward until the release block pushes the spring holder upward, causing the spring holder to rotate.

[0013] As a limitation: the clamping release pin is movably located on the top of the housing, and its upper end is used to connect with the lifting device of the UAV; a stop block is fixed above the rotating shaft that rotatably connects the clamping arm to the housing, and the stop block and the clamping arm rotate around the rotating shaft simultaneously; in the initial state of the clamping arm, the slot provided on the free end of the stop block is engaged with the clamping release pin and the release lever, and the clamping release pin and the release lever 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 lever, the clamping release pin is pulled out from above and disengaged from the grounding clamp, and the release lever can move up and down when the release handle is pulled upward.

[0014] As a limitation: the release handle includes a release base, on which a release ring or release claw for hooking onto the drone is fixed.

[0015] As a limitation, conductive copper sheets are fixedly provided at the contact points between the clamping port and the wire, on the side of the clamping arm that contacts the wire, and on the grounding wire base.

[0016] As a limitation, a guide plate is fixed 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.

[0017] As a limitation, the grounding clamp also includes an intelligent detection module, which includes a limit switch and a wireless communication unit connected by communication. The limit switch is fixed at the clamping opening to detect the state of the wire in the clamping opening, and the wireless communication unit is used to transmit signal data.

[0018] By adopting the above technical solution, the beneficial effects achieved by the present invention compared with the prior art are as follows: (1) The trigger rod in the clamping mechanism restricts the initial state of the clamping arm through the first locking pin limiting structure. When the wire generates an upward pushing force on the trigger rod and rotates clockwise, the limiting effect of the first locking pin limiting 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 whole clamping process is very simple and the clamping structure is stable and effective.

[0019] (2) When the grounding clamp is released (removed), the release handle is pulled to drive the release block to move upward and abut against and push the spring seat to rotate upward, so that the second slot loses its limiting effect on the second pin. 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 when it is in the compressed state, and the clamping arm returns to the initial position, thus achieving the purpose of quickly removing the grounding clamp from the wire.

[0020] (3) The clamping release pin can automatically detach from the housing after the grounding clamp holds the wire. This design can enable the UAV to hook and lift the grounding clamp. On the other hand, since the clamping release pin has an automatic detachment design, the UAV can be quickly separated from the grounding clamp after installation.

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

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

[0023] In summary, the clamping mechanism of this invention automatically clamps the conductor when placed on it by a drone. Simultaneously, during release, simply pulling the release ring or release claw upwards with the drone releases the clamp. Both clamping and releasing operations can be performed in conjunction with the drone, and the clamping and releasing mechanisms are quickly restored to their initial state after use, ready for the next application. This invention offers high clamping reliability and simple release operation, making it suitable for the maintenance of high-voltage transmission lines. Attached Figure Description

Detailed Implementation

[0026] The preferred embodiments of the present invention will now be described with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustrative and explanatory purposes only and do not constitute a limitation thereof.

[0027] The directional terms such as "clockwise" and "counterclockwise" or other terms indicating positional relationships used in this invention are based on the positional relationships in the accompanying drawings of this invention. They are only for the purpose of facilitating the description of this invention and simplifying the description. They do not indicate or imply that the device or component must have a specific orientation, or that it must be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the content protected by this invention. Example

[0028] like Figures 1-6 As shown, a grounding clamp device based on UAV control includes a housing 1 arranged in an inverted J-shape. The housing 1 includes a vertical portion and a curved portion, with the curved portion forming a downward-facing clamping opening 2. The grounding clamp is equipped with a clamping mechanism and a release mechanism. The wire can be automatically clamped and fixed in the clamping opening 2 by the clamping mechanism, and the grounding clamp can be detached and released from the wire using the release mechanism. A grounding wire base 4 for connecting a grounding wire 5 is fixed at the lower end of the housing 1.

[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 opening 2 to clamp the wire. The main spring 7 is located in the vertical part of the housing 1. The upper end of the main spring 7 is fixedly connected to an upper spring seat 9. The upper spring seat 9 and the middle part of the clamping arm 6 are rotatably connected through a horizontally set 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 can be movably locked on a spring seat 12. A telescopic rod is provided between the upper spring seat 9 and the lower spring seat 10. The two ends of the telescopic rod are fixedly connected to the upper spring seat 9 and the lower spring seat 10 respectively and extend and retract with the length of the main spring. A horizontally arranged second spring shaft 15 is mounted on the lower spring seat 10, with both ends of the second spring shaft 15 extending out of the lower spring seat 10. A vertically oriented sliding groove 25 is formed in the housing 1, allowing the two ends of the second spring shaft 15 to move up and down within the sliding groove 25 via a bearing structure. The two ends of the second spring shaft 15 extending out of the lower spring seat 10 are each provided with a reset push handle 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 port 2 and is positioned above the clamping arm 6. A first locking pin limiting structure is provided between the trigger rod 8 and the clamping arm 6 to limit the initial position of the clamping arm 6. When the trigger rod 8 is triggered and rotated at the clamping port 2 by the wire, the first locking pin 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 clamping position as shown in the image. Figure 3 The state shown in the image.

[0031] like Figure 4 , Figure 5 As shown, the first locking pin limiting structure includes a first locking pin 13, a first locking groove 14, and a first torsion spring (not shown in the figure). The first locking pin 13 is horizontally fixed on the clamping arm 6. A first locking groove 14 matching the first locking pin 13 is provided on the trigger rod 8. The first torsion spring is disposed on the rotating shaft that rotatably connects the trigger rod 8 and the housing 1. The first torsion spring can provide the trigger rod 8 with a torque that allows it to rotate counterclockwise around the rotating shaft and lock the first locking groove 14 with the first locking pin 13. This invention uses the first locking pin limiting structure to limit the initial state of the clamping arm 6. When the trigger rod 8 rotates clockwise under the upward pushing force generated by the wire, the first locking pin 13 disengages from the first locking groove 14, the limiting effect of the first locking pin limiting structure on the clamping arm 6 is released, the upper end of the main spring 7 is released, and under the pushing action of the spring, the clamping arm 6 is lifted upward to clamp the wire. The entire clamping process is simple and effective. A reset rotating handle 18 is fixed on the outside of the clamping arm 6 to reset the first locking pin limiting structure. By rotating the reset rotating handle 18, the first locking pin 13 can be re-locked in the first locking groove 14.

[0032] like Figure 4 , Figure 6 As shown, one end of the spring holder 12 is rotatably mounted on the housing 1. A second slot 16 is formed on the spring holder 12 for movably engaging and restricting the lower end of the main spring 7. The second spring shaft 15 also serves as a second locking pin, which matches the second slot 16. A second torsion spring (not shown in the figure) is provided at the rotatable connection between the spring holder 12 and the housing 1. The second torsion spring provides the spring holder 12 with torque to rotate counterclockwise around the shaft and engage the main second locking pin in the second slot 16.

[0033] The release mechanism can release the clamping and fixing effect of the clamping mechanism on the wire, allowing the grounding clamp to detach 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 located on the top of the housing 1 and includes a release base 20. A release ring 19 or a release claw for hooking onto the drone is fixed to the release base 20. The release handle facilitates the drone's disassembly and release of the grounding clamp. Specifically, the drone uses a lifting device or hook below it to pull the grounding clamp upwards. The specific shape of the release handle is not limited, as long as it facilitates hooking by the lifting device. This embodiment uses a circular release ring 19 structure, but a claw-shaped release structure or other structures in the prior art that facilitate 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 the release rod 21, which is vertically installed inside the housing 1. The lower end of the release rod 21 is fixedly connected to the release block 22, and the lower end of the release block 22 is connected to the bottom of the housing 1 through a tension spring 23. The free end of the spring holder 12 is located above the release block 22 and there is a safe distance between it and the release block 22. When the release handle is pulled upward, the release rod 21 and the release block 22 can be driven to move upward until the release block 22 abuts upward and pushes the spring holder 12 to rotate clockwise. Specifically, in the initial state when the grounding clamp is not used, the lower end of the main spring 7 is compressed in the second slot 16. When the spring holder 12 is lifted by the release block 22 and rotates clockwise, the restriction effect of the second slot 16 on the lower end of the main spring 7 is released, and there is enough space below the main spring 7 to allow it to return to its original length (i.e., without elasticity). As a result, the clamping arm 6 at the upper end of the main spring 7 is no longer subjected to upward thrust, and the clamping arm 6 rotates counterclockwise, disengaging from the clamping of the wire. At this point, the grounding clamp can be removed from the conductor, completing the separation and 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 the one hand, the clamping release pin 3 can connect the grounding clamp to the lifting device 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 detach from the housing 1 after the grounding clamp has completed the clamping operation on the wire, and then the drone can be operated to leave. The clamping release pin 3 also leaves with the drone. That is, the clamping release pin 3 is movably set on the top of the housing 1. Specifically, as shown in the figure... Figure 4As shown, a stop 24 is provided above the rotating shaft that rotatably connects the clamping arm 6 and the housing 1. The stop 24 and the clamping arm 6 rotate around the rotating shaft simultaneously. In the initial state of the clamping arm 6, the slot at the free end of the stop 24 is engaged with the clamping release pin 3, preventing the clamping release pin 3 from moving up and down. When the clamping arm 6 clamps the wire, the free end of the stop 24 has rotated clockwise and left the clamping release pin 3, and the lower end of the clamping release pin 3 is no longer constrained and can be pulled out from above to detach from the grounding clamp. At the same time, the stop 24 can also prevent the release lever 21 from being accidentally pulled up. Specifically, in the initial state of the clamping arm 6, the slot at the free end of the stop 24 can be engaged with the release lever 21, preventing the release lever 21 from moving up and down. When the clamping arm 6 finishes clamping the wire, the free end of the stop 24 rotates away from the release lever 21, at which point the release lever 21 can move up and down when the release handle is pulled upwards.

[0035] The grounding function of the grounding clamp is achieved by bringing the conductor into contact with the ground. In this embodiment, conductive copper sheets 26 are fixed at the contact point between the clamping opening 2 and the conductor, on the side of the clamping arm 6 that contacts the conductor, and on the grounding wire base 4. Connecting copper wires are provided inside the housing 1. With this configuration, the grounding wire 5 connected to the grounding wire base 4 is connected to the conductor through the copper sheets and the connecting copper wires.

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

[0037] like Figure 2 As shown, the present invention also includes an intelligent detection module 28, which includes a limit switch 29 and a wireless communication unit (not shown in the figure) connected by communication. The limit switch 29 is a micro switch, with its spring fixed downward 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, the limit switch 29, and the wireless communication unit are all existing technologies.

[0038] The method of using this invention is as follows: The grounding clamp, initially set and connected to the grounding wire 5, is hooked onto a lifting device below the drone via the clamping release pin 3. The drone is then operated to lift the grounding clamp above the high-altitude conductor. Under the guidance of the guide plate 27, the clamping opening 2 of the grounding clamp is lowered towards the conductor until the conductor enters the clamping opening 2. Once the conductor touches the trigger rod 8 and exerts an upward pushing force on it, the trigger rod 8 rotates slightly clockwise and lifts up. The first locking pin limiting structure is opened, thus releasing the restriction of the clamping arm 6. The upper end of the main spring 7 is released, and the clamping arm 6 rotates clockwise under the upward elastic force of the main spring 7, thereby clamping the conductor. At this time, the conductor is clamped in the clamping opening 2, the spring of the limit switch 29 is pressed, and a signal is sent to the intelligent detection module 28. During the process of the clamping arm 6 clamping the conductor, the intelligent detection module 28 monitors and provides feedback on the usage status of the grounding clamp in real time.

[0039] After the maintenance work is completed, when it is necessary to disassemble the grounding clamp, control the drone to fly above the grounding clamp, hook the release handle (release ring 19 or release claw) fixed at the upper end of the grounding clamp onto the lifting device below the drone, and pull the release handle upward, which will drive the release lever 21 and release block 22 to move upward, so that the second slot 16 loses its limiting effect on the second locking pin, the lower end of the main spring 7 is released and returns to its original length, and the clamping arm 6 also returns to its initial position. At this time, the grounding clamp can be removed from the wire.

[0040] The grounding clamp is manually restored to its initial state as follows: First, place the clamping release pin 3 back into its original position, then lift the reset handle 18 upwards and rotate it counterclockwise. The reset handle 18 drives the clamping arm 6 to rotate until the stop block 26 fixed on the clamping arm 6 rotates to its initial state. At this time, the stop block 26 re-fixes the positions of the clamping release pin 3 and the release lever 21, and the first locking pin 13 of the clamping arm 6 is engaged in the first slot 14 on the trigger rod 8. Then, push the reset push handle 17 upwards 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 slot 16 on the spring holder 12. At this time, the reset of all mechanisms is completed, and the grounding clamp returns 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 this disclosure, and are not intended to limit them. Although this disclosure has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this disclosure.
