Description

Technical Field

[0001] This utility model belongs to the field of power transmission line maintenance technology, and in particular relates to a grounding wire mounting device based on a drone. Background Technology

[0002] Safety regulations for power transmission (distribution) lines require that after a power outage, voltage testing and grounding wire installation must be performed before any work can commence, and the grounding wire must be removed before power can be restored. Traditional methods for voltage testing and grounding wire installation on transmission and distribution lines primarily involve manual climbing of towers, which carries extremely high operational risks.

[0003] First, during the climbing process, staff members need to carry tens of kilograms of grounding wires, voltage detectors, and operating rods. The heavy load makes it easy for them to lose protection during climbing and transfer, which can easily lead to falls from heights.

[0004] Secondly, because poles, towers, and overhead lines are distributed in the horizontal space, it is not easy for staff to determine whether the line is energized. If the wrong line is selected or the grounding wire is attached without verifying the voltage, there is a high possibility of a serious misoperation incident of attaching a grounding wire while the line is energized.

[0005] Third, in the case of de-energized lines adjacent to live power lines, workers are prone to electric shock due to induced current when installing or removing grounding wires without the protection of personal safety wires. Utility Model Content

Detailed Implementation

[0032] It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0033] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0034] Please see Figures 1 to 4 As shown, this embodiment provides a grounding wire mounting device based on a drone, including:

[0035] The traction bracket 1 is equipped with an electro-hydraulic mechanism and a guide rope is attached to the traction bracket 1.

[0036] The connecting plate 2 has a clamping component on its upper end surface. The clamping component cooperates to form a clamping position for clamping and holding the overhead line. The clamping component is connected to the traction bracket 1 through a linkage mechanism. The lower end surface of the connecting plate 2 is connected to the output shaft end of the electro-hydraulic mechanism.

[0037] The clamping component is also equipped with an elastic limiting mechanism 5 for limiting the overhead line;

[0038] The clamping component and traction bracket 1 are also connected to a grounding wire, which is connected to the grounding point on the ground.

[0039] Specifically, in this embodiment, the device is currently applicable to voltage testing and grounding work on single-line power transmission and distribution lines with an up-and-down arrangement of less than 35 meters. Based on the actual field trial of voltage testing and grounding work on 110kV lines, the operation time has been shortened from 60 minutes to 40 minutes, improving work efficiency by about 33%.

[0040] The device employs a method where a drone drops a traction rope, a person manually pulls the assembly / disassembly device to the grounding position of the conductor, and ground personnel use remote control to lock the mechanical structure of the assembly / disassembly device to the grounding position of the conductor to establish a grounding circuit. The entire process does not require personnel to climb the tower.

[0041] Furthermore, in this embodiment, a hook point for attaching the guide rope is provided on the traction bracket 1, and an electro-hydraulic mechanism is installed on the traction bracket 1. The electro-hydraulic mechanism is remotely controlled by ground personnel to control the up-and-down movement of the connecting plate 2 connected to the output shaft end of the electro-hydraulic mechanism, thereby realizing the opening and closing of the clamping component. At the same time, grounding wires are attached to the clamping component and the traction bracket 1, and the other end of the grounding wire is connected to the grounding point on the ground. By clamping or releasing the overhead line, the hanging and dismantling device can lock the wire to complete the grounding or release the contact grounding.

[0042] In addition, this embodiment provides an elastic limiting mechanism 5 on the clamping member. The elastic limiting mechanism 5 can be adapted to power transmission conductors of different diameters by means of its extensibility, thereby improving the flexibility and adaptability of the device.

[0043] The grounding wire attaching device based on a drone described in this embodiment uses a drone to deploy and attach the grounding wire to the grounding point of the power transmission and distribution line, effectively avoiding the risk of high-voltage electric shock and falls from heights for workers, and improving the safety factor and work efficiency.

[0044] In some implementations, such as Figure 1 and Figure 2 As shown, the traction bracket 1 includes a traction plate 11 and a mounting bracket 12 disposed at the bottom of the traction plate 11. Through holes 13 for attaching guide ropes are provided on both sides of the traction plate 11.

[0045] A through hole is provided in the center of the traction plate 11. The electro-hydraulic mechanism is fixed in the mounting bracket 12 through the mounting base provided at the bottom. The output shaft end of the electro-hydraulic mechanism passes through the through hole and is connected to the connecting plate 2.

[0046] Specifically, in this embodiment, holes are drilled on both sides of the traction plate 11 to provide a fixed position for connecting the guide rope. The drone pulls the guide rope to drive the device up and down, thereby completing the attachment and detachment of the overhead line.

[0047] The electro-hydraulic mechanism used in this embodiment is a common combination of motor and hydraulic drive. The output shaft of the hydraulic drive motor extends and retracts to drive the connecting plate 2 to move up and down. The grounding wire electro-hydraulic device can be operated at the ground end to lock the wire to complete the grounding or release the contact grounding.

[0048] In some implementations, such as Figure 2 As shown, the edge of the traction plate 11 is provided with a plurality of first hinge parts 14, and the edge of the connecting plate 2 is provided with a plurality of second hinge parts 21.

[0049] The clamping component includes multiple sets of jaws and claws. Each set of jaws and claws includes two clamping claws arranged symmetrically. The clamping claws are hinged to the first hinge part 14 via the connecting rod 3, and the clamping claws are hinged to the second hinge part 21.

[0050] Each gripper includes two gripping plates 41 with a gap between them. The bottom ends of the two gripping plates 41 are respectively hinged to the connecting rod 3 and the second hinge part 21.

[0051] The clamping plate 41 has an arc-shaped structure, and an ear extends outward from the clamping plate 41. A through hole 42 is provided on the ear, and a grounding wire is hung on the through hole 42.

[0052] A rubber gasket 43 is also installed in the gap reserved between the two clamping plates 41.

[0053] Specifically, in this embodiment, the following explanation is given using two sets of jaw grippers as an example. The two sets of jaw grippers are located at the two side edges of the connecting plate 2. Each set of jaw grippers includes two rotatable gripping claws. The bottom end of the gripping claws is hinged to the second hinge part 21 provided on the connecting plate 2, and is also hinged to the first hinge part 14 of the traction plate 11 through the connecting rod 3. The two gripping claws are driven by a motor to perform closing and opening actions, thereby achieving the clamping and releasing of the wire.

[0054] It should be noted that in this embodiment, each clamping claw is composed of two arc-shaped clamping plates 41, and a gap is reserved between the two clamping plates 41. This is to enable the clamping plates 41 to connect with the first hinge part 14 and the connecting rod 3, and to improve the clamping stability of the jaws.

[0055] Meanwhile, an ear extends from the clamping plate 41, and a through hole 42 is opened on the ear. The purpose of the reserved through hole 42 is to hang the grounding wire. In this embodiment, the grounding wire is a single wire with a built-in 25m2 copper wire. The copper wire is fixed in the through hole 42. At the same time, it is connected to the grounding point on the ground together with the grounding wire set on the traction bracket 1, so that after the hanging and dismantling device is hung on the overhead line, the grounding wire is connected to the overhead line to realize the grounding of the overhead line.

[0056] In some embodiments, a plug-in hole is provided at the middle position of the clamping plate 41;

[0057] like Figure 3 As shown, the elastic limiting mechanism 5 includes a double hook tension spring 51 and a limiting pin 52. The limiting pin 52 is inserted into the insertion hole, and the double hook tension spring 51 is hooked onto the clamping plates 41 on both sides.

[0058] Specifically, in this embodiment, each clamping plate 41 is provided with a plug-in hole, into which a limit pin 52 is inserted. The rod end of the limit pin 52 is provided with a connecting hole, and the double hook spring 51 is hooked into the connecting hole. The purpose of this setting is to adapt to transmission wires of different diameters. Specifically, when the clamping jaws are opened, the double hook spring 51 is stretched. Then, for transmission wires with smaller diameters, they will be locked into the double hook spring 51 and cooperate with the clamping jaws to achieve the fixed locking of transmission wires with smaller diameters, thereby improving the hooking effect of transmission wires.

[0059] In some implementations, such as Figure 4 As shown, the upper surface of the connecting plate 2 is provided with multiple support plates 22, which are located in the empty area between the two sets of clamping jaws. The upper surface of the support plate 22 is reserved with an arc-shaped opening that matches the overhead cable.

[0060] Specifically, in this embodiment, multiple support plates 22 are provided on the connecting plate 2 to effectively support the bottom of the transmission line, thus providing auxiliary support.

[0061] It should be noted that, due to the presence of the double hook spring 51, when the transmission line presses down on the double hook spring 51, the lowest point of the double hook spring 51 and the lowest point of the arc on the support plate 22 are kept on the same horizontal line to improve the clamping effect on the transmission line.

[0062] The working principle of this device is as follows:

[0063] Using the aforementioned attachment device, one end of the guide rope is fixed in the through hole of the traction bracket, and the other end is connected to the load-bearing block. The load-bearing block is then placed on the drone. At the same time, one end of the grounding wire is connected to the clamping plate and the traction bracket, and the other end is connected to the ground grounding point. Meanwhile, during the preparation phase, after the hydraulic drive mechanism connection line is in place, all connection points are checked to ensure they are accurate.

[0064] Ground personnel control and release the drone, which takes off and lifts off, pulling the traction rope across the power transmission line. Then, the weight block is released, allowing the weight block to pull the guide rope down to the ground on the other side of the power transmission line by its own weight.

[0065] During the connection operation, the ground operator manually pulls the guide rope to pull the connection device to the grounding position of the power transmission line. At this time, the clamping jaws are in the open state. Due to the large opening angle, the power transmission line is exactly located in the opening of the clamping jaws. Then, the drone is launched again to observe and confirm whether the power transmission line has accurately entered the clamping jaws, thereby improving the success rate of the drone connecting and disconnecting the grounding wire.

[0066] Once the power transmission line is accurately inserted into the jaws of the clamping jaws, ground personnel remotely control the electro-hydraulic mechanism to grip the power transmission line, thus completing the grounding wire connection operation.

[0067] When removing the attachment device, ground personnel remotely control the electro-hydraulic mechanism to open the clamping claws, detach them from the overhead line, and then use a drone to carry the load-bearing block over the overhead line and release the attachment device to the ground to remove the grounding point and complete the removal of the grounding wire.

[0068] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model 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.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
