Description

Technical Field

[0001] This invention belongs to the field of electrical safety technology, and in particular relates to a pull-and-connect grounding wire device. Background Technology

[0002] Grounding wires for transmission lines are one of the safety measures for maintenance workers. They are widely used in the construction and maintenance of transmission lines. Power grid safety regulations clearly require that safety measures such as power outage, voltage testing, grounding, and hanging of warning signs must be implemented before maintenance work. Among these, grounding is a key safety measure for maintenance work. After the line is de-energized, the grounding wires need to be hung or removed on both sides of the maintenance work area to ensure the safety of maintenance workers and prevent safety hazards caused by induced electricity or misoperation.

[0003] Currently, the traditional method of installing and removing grounding wires requires manual climbing of the tower to test for voltage and install / remove the grounding wires. Manually climbing the tower not only poses high safety risks but is also time-consuming and labor-intensive, affecting the reliability of power supply.

[0004] With the continuous advancement of drone technology, drones have been widely used in various industries. In response, the applicant has designed a pull-and-attach grounding wire device that can be towed by a drone to eliminate the shortcomings of manual pole climbing and attachment. Summary of the Invention

[0005] The purpose of this invention is to provide a pull-and-attach grounding wire device, which can be attached and detached by drone towing, thus eliminating the high safety risks and time-consuming and labor-intensive nature of existing manual pole climbing operations.

[0006] To address the aforementioned problems, this application provides a pull-and-connect grounding wire device: The device includes a quick-connect mechanism comprising a U-shaped connector and a locking mechanism. One end of the U-shaped connector is provided with a terminal block for connection to a grounding cable. The locking mechanism includes at least one set of locking components, each set of locking components including a pulling member and a locking rod. The locking rod is located at the opening of the U-shaped connector. One end of the locking rod is hinged to the U-shaped connector via a torsion spring shaft, and the other end is connected to the pulling member. In the reset state, the locking rod locks the opening of the U-shaped connector. The pulling member and the locking rod form an acute angle and extend to the outside of the U-shaped connector. The external pulling force and gravity work together to drive the locking rod to rotate relative to the torsion spring shaft through the pulling member, thereby opening the opening of the U-shaped connector.

[0007] As a preferred embodiment of this application: the U-shaped hook joint has a hollow internal structure, and the pulling member passes through the hollow cavity of the U-shaped hook joint after the roller is reversed and extends to the top of the U-shaped hook joint to connect with a pulling ring.

[0008] As a preferred embodiment of this application: the locking assembly comprises two sets, which are symmetrically arranged and lock the opening of the U-shaped hook in the reset state. The corresponding pull members of the two sets of locking assemblies extend to the top of the U-shaped hook and are connected to the pull ring. Pulling the pull ring and cooperating with gravity can drive the two sets of locking assemblies to swing synchronously, thereby opening the opening of the U-shaped hook.

[0009] As a preferred embodiment of this application: the bottom of the pull ring is provided with a limiting post, which abuts against the top of the U-shaped hook connector in the reset and locked state.

[0010] As a preferred embodiment of this application: the torsion spring shaft is disposed inside the corresponding end side of the U-shaped hook connector, and a travel groove for the locking rod to swing is provided on the corresponding end side.

[0011] As a preferred embodiment of this application: when the locking mechanism includes a set of locking components, an extension handle is provided on the end side of the U-shaped hook connector where the locking mechanism is located, and the terminal block is located near the end of the extension handle.

[0012] As a preferred embodiment of this application, it includes a grounding cable with a connector for connection to the terminal block.

[0013] As a preferred embodiment of this application: the traction member is made of a flexible material, and the locking rod is made of a rigid material.

[0014] As a preferred embodiment of this application, the quick-attachment mechanism is used in conjunction with the UAV for attachment.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: This grounding wire device includes a quick-connect mechanism. This mechanism abandons the traditional locking structure that uses pressing or rotating methods, instead employing a pulling method to drive a locking assembly consisting of a pulling member, a locking rod, and a torsion spring shaft, thereby controlling the opening and closing of the U-shaped connector. This method, through the combination of external pulling force and the device's own weight, not only enables the rapid connection of the U-shaped connector to overhead cables, improving connection efficiency, but also eliminates the need for manual pole climbing, reducing operational safety risks. The pulling force is provided by an external device, preferably a drone, but can also be any device capable of providing pulling force, such as a long-arm pole. Therefore, this grounding wire device, by replacing the traditional manual pole climbing connection method with a pulling connection method, improves connection efficiency and safety, resulting in significant economic benefits.

Detailed Implementation

[0025] The present invention will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be emphasized that the following description is merely exemplary and not intended to limit the scope and application of the present invention.

[0026] This embodiment provides a pull-and-connect grounding wire device. The device includes a quick-connect mechanism and, if necessary, a grounding cable 80. The quick-connect mechanism includes a U-shaped connector 10 and a locking mechanism. The U-shaped connector 10 is conductive, and one end of the U-shaped connector 10 is provided with a terminal block 60 for connection to the grounding cable 80. It is understood that the terminal block 60 is a conventional bolt terminal block, and the grounding cable 80 can be a conventional grounding wire. The grounding cable 80 should have a connector corresponding to the bolt terminal block. The locking mechanism includes at least one set of locking components, such as... Figure 1As shown in Figure 2, each locking assembly includes a pulling member 21 and a locking rod 22. The locking rod 22 is located at the opening of the U-shaped hook joint 10. One end of the locking rod 22 is hinged to the U-shaped hook joint 10 via a torsion spring shaft 30, and the other end, i.e., the free end, is connected to the pulling member 21 and locks the opening of the U-shaped hook joint 10 in the reset state. It can be understood that the locking rod 22 should be a rigid structure. In this embodiment, the locking rod 22 preferably uses a rigid rod of the same material as the U-shaped hook joint 10, and the locking rod 22 is a rigid structure. When rod 22 swings relative to torsion spring shaft 30, it should not affect the normal engagement and disengagement of U-shaped hook joint 10; the pulling member 21 forms an acute angle with the locking rod 22 and extends to the outside of U-shaped hook joint 10. The acute angle design facilitates the application of pulling force to the pulling member 21 and, together with the weight of the device itself, drives the locking rod 22 to overcome the torque of torsion spring shaft 30 and swing upward, thereby opening the opening of U-shaped hook joint 10; understandably, the reset torque of torsion spring shaft 30 should ensure that the locking rod 22 can be reset to the locked state.

[0027] In this embodiment, the pulling member 21 is made of a flexible material, specifically a flexible pulling rope, which is connected to the locking rod 22 by bolts, such as... Figure 8 As shown, the pull rope and the locking bar 22 can be connected by binding. Of course, if necessary and feasible, the pull member 21 can also be made of rigid material. One end of the pull member 21 is hinged to the locking bar 22, and the other end passes through the U-shaped hook joint 10 and extends to the outside.

[0028] In this embodiment, the U-shaped hook connector 10 has a hollow internal structure, that is, the U-shaped hook connector 10 is formed by bending a hollow steel pipe. The pulling member 21, that is, the pulling rope, passes through the hollow cavity of the U-shaped hook connector 10 after being reversed by the roller 40 and extends to the top of the U-shaped hook connector 10 to connect with a pulling ring 50. Extending the pulling rope to the top of the U-shaped hook connector 10 makes it easy for the U-shaped hook connector 10 to remain upright and not tilted when external pulling force is applied, thus facilitating quick hooking and unhooking.

[0029] like Figure 1 As shown, the locking mechanism provided in this embodiment includes a pull-and-hook grounding wire device with two sets of locking components. In this structure, both the locking rod 22 and the pull member 21 include two sets. The two sets of locking components are symmetrically arranged in the opening of the U-shaped hook connector 10 and lock the opening of the U-shaped hook connector 10 in the reset state. That is, the two sets of locking components in the reset state and the opening of the U-shaped hook connector 10 form a hooking ring that can be hooked onto the cable. The pull members 21 corresponding to the two sets of locking components extend to the top of the U-shaped hook connector 10 and are connected to the pull ring 50. Figure 3As shown in the cross-sectional view provided in this embodiment, the pull ropes corresponding to the two sets of locking components pass around the corresponding rollers 40 and extend through the hollow cavity to the top of the U-shaped hook joint 10. It can be understood that the two sets of pull ropes are merged into one at the top of the U-shaped hook joint 10 and connected to the bottom of the pull ring 50. Pulling the pull ring 50, combined with gravity, can cause the locking rods 22 of the two sets of locking components to swing upwards synchronously relative to the corresponding torsion spring shafts 30, thereby opening the opening of the U-shaped hook joint 10. Figure 6-7 As shown, at the same time, the height of the device body is raised by the pulling force. When the predetermined height is reached, the U-shaped connector 10 can be hung on the corresponding overhead cable 90. Then the external pulling force is released, and the locking rods 22 of the two sets of locking components are reset under the drive of the corresponding torsion spring shafts 30, thereby locking the U-shaped connector 10 and completing the hanging. When disassembling, the external pulling force can be used again to drive the pulling ring 50 and the pulling member 21 to move the locking rod 22 to open the opening of the U-shaped connector 10. With further lifting, the quick hanging mechanism is disengaged from the overhead cable 90.

[0030] like Figure 2 As shown, the locking mechanism provided in this embodiment includes a pull-and-hook grounding wire device comprising a set of locking components. In this structure, both the locking rod 22 and the pulling member 21 are included as a set. The length of the locking rod 22 is equal to or slightly less than the opening width of the U-shaped hook connector 10 to ensure that the opening is blocked in the reset state. It is understood that, to prevent the locking rod 22 from swinging relative to the torsion spring shaft 30 and affecting the normal hooking and unhooking of the U-shaped hook connector 10, when the locking components are a set, the depth of the U-shaped groove of the U-shaped hook connector 10 can be increased to be greater than the running trajectory of the locking rod 22 swinging around the torsion spring shaft 30. The pulling member 21 extends to the top of the U-shaped hook connector 10 and connects to the pulling ring 50. In use, the pulling ring is pulled... 50. With the help of gravity, the pulling member 21 can drive the locking rod 22 to overcome the torque of the torsion spring shaft 30 and swing upward, thereby opening the opening of the U-shaped connector 10. At the same time, the height of the device body is raised by the pulling force. When the predetermined height is reached, the U-shaped connector 10 can be hung on the corresponding overhead cable 90. Then the external pulling force is released, and the locking rod 22 of the locking component is reset under the drive of the torsion spring reset force, thereby locking the U-shaped connector 10. At this time, the hanging is completed. When disassembling, the external pulling force can be used again to drive the pulling ring 50 and the pulling member 21 to move the locking rod 22 to open the opening of the U-shaped connector 10. With further lifting, the quick hanging mechanism is disengaged from the overhead cable 90.

[0031] The pulling force is provided by an external device, which can be a drone or a long boom or other device capable of providing pulling force. In this embodiment, a drone is preferred, that is, the quick-attachment mechanism is used in conjunction with the drone. Drone technology is mature and can be remotely controlled, which meets the requirements of this embodiment.

[0032] In this embodiment, to improve the overall compactness of the device, the torsion spring shaft 30 is preferably located inside the corresponding end side of the U-shaped hook connector 10, and a stroke groove 70 for the locking rod 22 to swing is provided on the corresponding end side, such as... Figure 4 As shown; the torsion spring shaft 30 is set in the hollow tube of the U-shaped hook joint 10 through the stroke groove 70 and then locked by bolts. It can be understood that one end of the torsion spring shaft 30 should abut against the inner wall of the hollow tube, and the other end should be fixed to the locking rod 22. When the locking rod 22 swings relative to the torsion spring shaft 30, the stroke groove 70 provides it with swing space.

[0033] In this embodiment, to improve the overall compactness of the device, the roller 40 is preferably disposed within the hollow tube of the U-shaped hook joint 10, such as... Figure 5 As shown, of course, if necessary, it can also be set on the inner wall of the opening of the U-shaped hook joint 10. After the locking rope passes around the roller 40 and changes direction, it extends through the hollow cavity to the top of the U-shaped hook joint and connects with the pulling ring 50. In this embodiment, the main function of the roller 40 is to realize the reversal and movement of the locking rope, improve the flexibility of the locking rope pulling and moving, and reduce friction.

[0034] In this embodiment, the main function of the traction ring 50 is to cooperate with traction equipment such as drones. As the name suggests, the traction ring 50 is a ring structure, and the size of the ring can be set according to actual needs. In order to ensure that the traction ring 50 can remain upright and avoid tipping over, which would be detrimental to docking with the traction equipment, it is preferable to provide a limiting post 51 at the bottom of the traction ring 50. In the reset and locked state, the limiting post 51 abuts against the top of the U-shaped hook connector 10. It can be understood that the abutting force between the limiting post 51 and the top of the U-shaped hook connector 10 should be provided by the reset torsion spring force of the torsion spring shaft 30 on the locking assembly. The mutual abutment between the limiting post 51 and the top of the U-shaped hook connector 10 provides support force for the column on the one hand, ensuring that it is in an upright state, and on the other hand, avoids deformation and other phenomena caused by the traction ring 50 directly contacting the U-shaped hook connector 10 under the action of the torsion spring force, thereby improving the service life of the traction ring 50.

[0035] In a preferred embodiment of this invention, when the locking mechanism includes a set of locking components, an extension handle 11 is provided on the end of the U-shaped hook connector 10 where the locking mechanism is located, such as... Figure 2 As shown, the terminal block 60 is located near the end of the extension handle 11. In this embodiment, the specific length of the extension handle 11 is selected according to actual needs. The extension handle 11 provides counterweight for the U-shaped hook connector 10, which is convenient to cooperate with the pulling force to drive the torsion spring shaft 30 to deform. On the other hand, the extension handle 11 serves as an extension of the grounding cable 80, reducing the length of the grounding cable 80.

[0036] The specific operating principle of this embodiment includes: First, connect the grounding cable 80 to the bolt terminal near the end of the extension handle 11. Then, connect the grounding device to the drone via the pull ring 50. The drone provides traction or pulling force to the entire grounding device.

[0037] Staff operate a drone to lift the grounding wire device. During the lifting process, the grounding wire device's own weight causes the pull rope to move relative to the roller 40 within the cavity of the U-shaped connector 10. This, in turn, causes the locking rod 22 to swing upward against the torsion spring force, opening the opening of the U-shaped connector 10. When the grounding wire device is lifted by the drone to the designated position of the overhead cable 90, the drone is operated to place the U-shaped connector 10 on the corresponding overhead cable 90. Then, the drone disengages from the pull ring 50, at which point the pulling force disappears. The pull rope resets under the action of the torsion spring's reset force, thereby driving the locking rod 22 to reset and lock the opening of the U-shaped connector 10, completing the remote mounting of the grounding wire device. During disassembly: Control the drone to connect with the pull ring 50, the drone lifts the grounding wire device, and at the same time, under the action of the device's own weight, the lock rod 22 will be moved upward through the pull ring 50 and the pull rope, thereby opening the opening of the U-shaped connector 10. With further lifting, the U-shaped connector 10 will detach from the overhead cable 90.

[0038] It should be noted that, due to the maturity of drone technology, which has the ability to flip and tilt at multiple angles, even if the U-shaped connector 10 tilts before and after the connection, it will not affect the overall connection and disassembly effect in actual use.

[0039] In summary, the grounding wire device of this solution, when used in conjunction with a drone, not only enables the U-shaped connector 10 to be quickly attached to the cable, improving the attachment efficiency, but also eliminates the need for manual pole climbing, reducing operational safety risks and resulting in significant economic benefits. Furthermore, it can be remotely controlled without actual human intervention, and the mature technology of drones can prevent abnormal attachment and removal phenomena, thus improving the reliability of attachment and removal.

[0040] The above descriptions are merely embodiments of the present invention, and common knowledge regarding specific structures and characteristics in the solutions is not described in detail here. It should be noted that those skilled in the art can make several improvements without departing from the present invention, and these should also be considered within the scope of protection of the present invention. These improvements will not affect the effectiveness of the implementation of the present invention or the practicality of the patent. The scope of protection claimed in this application should be determined by the content of the claims, and the specific embodiments described in the specification can be used to interpret the content of the claims.
