Description

Technical Field

[0001] This invention relates to the field of power equipment technology, and in particular to a device for quickly installing grounding wires. Background Technology

[0002] When performing maintenance work on power distribution lines, grounding devices must be installed on the overhead distribution lines after the power is cut off to connect the overhead lines to the ground, so as to avoid electric shock accidents caused by sudden power restoration, induced current in the lines, and lightning strikes during line maintenance.

[0003] Currently, the installation and removal of grounding wires are often done manually, and the methods can be divided into two types depending on the height of the overhead conductor. One method, when the overhead conductor is low, involves workers using insulated telescopic poles to attach grounding wire clamps to the conductor; this method is efficient but has poor connection stability. The other method, when the overhead conductor is high, involves workers carrying grounding wire devices and climbing poles to the overhead line to install and remove the grounding wires. This method is flexible and widely applicable, but requires manual climbing, posing safety hazards such as falls from height and electric shock, and is labor-intensive, resulting in longer operation times and lower efficiency. Furthermore, when installing grounding wires on high overhead lines, workers experience significant psychological stress due to the high-altitude environment, which can affect the stability of the grounding wire installation. In addition, current grounding wire installation and removal operations often require multiple workers to cooperate, greatly increasing the complexity, coordination difficulty, and construction costs.

[0004] Therefore, there is an urgent need to provide a device for quickly installing grounding wires to solve the above problems. Summary of the Invention

The winding shaft extends in a third direction, and the end of the insulated traction rope away from the attachment point is fixedly connected to the winding shaft.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection.

[0036] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0037] To simplify the work process and improve work efficiency, this embodiment provides a device for quickly installing grounding wires. The following describes the device in conjunction with... Figures 1 to 5 The specific content of this embodiment will be described in detail. It should be noted that the first direction mentioned in this embodiment is... Figure 2 The Z direction in this embodiment, and the second direction mentioned in this embodiment are Figure 2 The X direction in this embodiment refers to the third direction. Figure 2 in the Y direction.

[0038] like Figures 1 to 4As shown, the quick-connect grounding wire installation device in this embodiment includes an upper grounding mechanism 1 and three grounding mechanisms 2. The upper grounding mechanism 1 includes a lifting traction device 101, a telescopic rod assembly 102, a hanging point device 103, and an insulated traction rope 104. The telescopic rod assembly 102 is mounted on the lifting traction device 101 and can extend and retract along a first direction. One end of the insulated traction rope 104 is connected to the hanging point device 103, and the other end of the insulated traction rope 104 passes through the telescopic rod assembly 102 and is connected to the lifting traction device 101. The three grounding mechanisms 2 are staggered along the first direction. One of the grounding mechanisms 2 is fixedly mounted on the fixed rod 1021 of the telescopic rod assembly 102 via a first fixed arm 6 and is used to connect to the lower phase conductor. Another grounding mechanism 2 is fixedly mounted on the first telescopic rod 1022 of the telescopic rod assembly 102 via a second fixed arm 5 and is used to connect to the middle phase conductor. A third grounding mechanism 2 is mounted on the second telescopic rod 1023 of the telescopic rod assembly 102 via a transfer mechanism 4 and is used to connect to the upper phase conductor. The adapter 4 serves to fix and balance the center of gravity.

[0039] In summary, the rapid grounding wire installation device provided by this invention includes an insulated traction rope 104 mounted on a hanging point device 103. An insulated rod is used to hang the hanging point device 103 onto the upper phase conductor. Activating the lifting traction device 101 tightens the insulated traction rope 104, causing the rapid grounding wire installation device to move up and down along the insulated traction rope 104, enabling the rapid grounding wire installation device to autonomously move up and down the overhead line. The use of three grounding mechanisms 2 corresponding to the three conductors 3 in the three-phase power supply ensures high connection stability. By controlling the length of the first telescopic rod 1022, the distance between the two grounding mechanisms 2 corresponding to the lower phase conductor and the middle phase conductor is adjusted. By controlling the length of the second telescopic rod 1023, the distance between the two grounding mechanisms 2 corresponding to the upper phase conductor and the middle phase conductor is adjusted. This allows for sequential docking and clamping with each phase conductor 3. Adapting to the characteristics of vertical arrangement, it can quickly and accurately complete the connection of the grounding wire. The quick-installation grounding wire device is simple to operate, has a wide range of applications, and can replace the traditional manual grounding wire installation and removal operation mode, improving the efficiency and quality of grounding wire installation and removal operations. At the same time, it eliminates the safety hazards of falling from heights and electric shock, simplifies the operation process, and reduces construction costs.

[0040] For example, such as Figures 2 to 4As shown, the grounding mechanism 2 includes a fixed frame 201, a fixed guide block 202, and a movable guide block 203. The fixed end of the grounding wire on the fixed frame 201 is provided with a copper busbar terminal 2013, which is used to fix the grounding wire. The fixed guide block 202 is fixedly mounted on the fixed frame 201, and the movable guide block 203 is movably mounted on the fixed frame 201 and can move closer to or further away from the fixed guide block 202 in a second direction. A wire clamping groove is formed between the movable guide block 203 and the fixed guide block 202. When the conductor 3 enters the wire clamping groove, the conductor 3 is clamped by the cooperation of the movable guide block 203 and the fixed guide block 202.

[0041] Furthermore, the grounding mechanism 2 also includes a first motor 204 and a first lead screw 205. The first lead screw 205 is rotatably mounted on the fixed frame 201, and the first motor 204 is disposed within the fixed frame 201 and is drively connected to the first lead screw 205. The movable guide block 203 is threadedly connected to the first lead screw 205. The first motor 204 can drive the first lead screw 205 to rotate and drive the movable guide block 203 to move along the second direction. By controlling the working state of the first motor 204, the movable guide block 203 can clamp or loosen the wire 3.

[0042] Furthermore, the grounding mechanism 2 also includes a first guide rod 206, which is disposed within the fixed frame 201 and extends along the second direction. The movable guide block 203 is slidably sleeved on the first guide rod 206. By adding the first guide rod 206, it is easier to guide the movable guide block 203 to move only along the second direction relative to the first guide rod 206, thereby improving the movement accuracy.

[0043] Optionally, the outer wall of the fixing frame 201 is provided with a limit switch 2011 and a mounting post 2012. The grounding mechanism 2 also includes a pressure plate 207 and a return spring 208. The pressure plate 207 is slidably disposed on the fixing frame 201 and can move along a first direction. One end of the return spring 208 is connected to the mounting post 2012, and the other end of the return spring 208 is connected to the pressure plate 207. The pressure plate 207 can block the limit switch 2011. When wiring is required, the wire 3 applies a force to the pressure plate 207, causing the pressure plate 207 to move downward along the first direction and block the limit switch 2011. At this time, the wire 3 is completely inserted into the wire clamping groove. According to the signal of the limit switch 2011, the first motor 204 is started, causing the movable guide block 203 to approach the fixed guide block 202 and clamp the wire 3. When the wire 3 leaves the wire clamping groove, the pressure plate 207 moves upward and resets under the pull of the return spring 208.

[0044] Furthermore, the grounding mechanism 2 also includes a guide rod 209 and an electric locking rod 2010. The first section of the guide rod 209 is rotatably connected to the top of the fixing frame 201. The electric locking rod 2010 is located on the second section of the guide rod 209 and can be locked or unlocked with the movable guide block 203. The guide rod 209 has a first position that blocks the conductor 3 and a second position that avoids the conductor 3. During the upward movement of the grounding mechanism 2, when passing a non-corresponding conductor 3, the electric locking rod 2010 extends its movable rod, causing structural interference between the movable rod and the movable guide block 203. Even if the conductor 3 presses against the guide rod 209, the guide rod 209 cannot rotate downwards, preventing the non-corresponding conductor 3 from entering the clamping groove of the grounding mechanism 2. Only when the corresponding conductor 3 presses against the guide rod 209 does the electric locking rod 2010 retract its movable rod, allowing the guide rod 209 to rotate and facilitating the entry of the conductor 3 into the clamping groove.

[0045] Furthermore, such as Figure 1 Combination Figure 5 As shown, the lifting traction device 101 includes a mounting frame 1011 and a winding shaft 1012 rotatably mounted on the mounting frame 1011. The winding shaft 1012 extends along a third direction. One end of the insulated traction rope 104 away from the hanging point device 103 is fixedly connected to the winding shaft 1012. The insulated traction rope 104 can be wound around the circumferential wall of the winding shaft 1012. When the hanging point device 103 is hung on the conductor 3, the winding shaft 1012 rotates in the forward direction, causing the insulated traction rope 104 to wind around the winding shaft 1012, thereby causing the quick-hanging grounding wire device to rise in the first direction; when the winding shaft 1012 rotates in the reverse direction, the quick-hanging grounding wire device descends in the first direction.

[0046] Furthermore, the lifting traction device 101 also includes a second lead screw 1013, a rope-arranging block 1014 with a threaded hole 10141, and a connecting block 1015. The second lead screw 1013 is rotatably mounted on the mounting bracket 1011. The connecting block 1015 has a threaded hole, and is threadedly connected to the second lead screw 1013 and can move in a third direction. The rope-arranging block 1014 is fixedly connected to the connecting block 1015, and the insulated traction rope 104 passes through the threaded hole 10141. The rotation of the second lead screw 1013 can move the rope-arranging block 1014 in a third direction, facilitating the orderly spiral winding of the insulated traction rope 104 onto the take-up shaft 1012 and avoiding a messy distribution of the insulated traction rope 104. Optionally, several reels can be added to the take-up shaft 1012 to store the insulated traction rope 104 between adjacent reels.

[0047] Furthermore, the lifting traction device 101 also includes a second guide rod 1016, which is fixedly mounted on the mounting bracket 1011 and extends along a third direction. The connecting block 1015 has a guide through hole and is slidably sleeved on the second guide rod 1016. By adding the second guide rod 1016, it is easier to guide the connecting block 1015 to move only along a third direction.

[0048] Furthermore, the lifting traction device 101 also includes a second motor 1017 and a drive wheel 1018. The second motor 1017 is mounted on the mounting bracket 1011. The drive wheel 1018 is coaxially connected to the shaft of the second motor 1017. One end of the second lead screw 1013 is provided with an intermediate wheel 1019, and one end of the take-up shaft 1012 is provided with a transmission wheel 1020. The drive wheel 1018, intermediate wheel 1019, and transmission wheel 1020 are connected by belt drive, chain drive, or gear drive. By driving the rotation of the drive wheel 1018 through the second motor 1017, the second lead screw 1013 and the take-up shaft 1012 can rotate simultaneously, which not only reduces the number of drive sources used but also facilitates a compact structural layout.

[0049] Understandably, the upper phase grounding mechanism is located at the top of the device. When the entire device starts to rise from the top, since the whole device rises vertically, its top will successively contact the lower phase and middle phase conductors. At this time, the guide rod 209 is in its initial state, playing a guiding role to make the conductor 3 slide downward. Only after approaching the upper phase conductor, the movable rod of the electric locking rod 2010 at the end of the guide rod 209 retracts. Under the pressure of the conductor 3, the guide rod 209 moves downward, and the upper phase conductor enters the clamping groove under the guidance of the fixed guide block 202 and presses down on the pressure plate 207 until the pressure plate 207 triggers the limit switch 2011 to act, and the device stops rising. The activation of limit switch 2011 triggers a signal, causing the first motor 204 to rotate and drive the first lead screw 205 to slowly move the movable guide block 203 towards the fixed guide block 202. When the conductor 3 is locked in the circular clamping groove, the movable guide block 203 cannot move further. The current in the first motor 204 continuously increases to a threshold value, controlling the first motor 204 to stop moving. At this point, the conductor 3 is clamped by the grounding mechanism 2, completing the effective conduction between the grounding wire and the conductor 3. The middle-phase grounding mechanism and the lower-phase grounding mechanism are structurally and operationally the same as the upper-phase grounding mechanism.

[0050] The workflow of the quick grounding wire installation device in this embodiment is as follows:

[0051] (1) Using a drone or an insulated telescopic component, the hanging point device 103, equipped with an insulated traction rope 104, is hung on the upper phase conductor of a vertical three-phase power line. The insulated traction rope 104 is wound onto the winding shaft 1012 of the upper winding mechanism 1. The upper winding mechanism 1 is then activated to wind up the insulated traction rope 104, thereby lifting the device onto the upper line. Figure 1 As shown;

[0052] (2) The device slowly rises, and first the lower phase grounding mechanism completes the clamping with the lower phase conductor and the grounding wire is connected;

[0053] (3) Then control the extension of the first telescopic rod 1022 so that the middle phase grounding mechanism contacts the middle phase conductor and clamps it to complete the connection with the grounding wire.

[0054] (4) Finally, control the extension of the second telescopic rod 1023 while simultaneously winding up the insulating traction rope 104, so that the upper phase grounding mechanism is close to the upper phase conductor and clamps, completing the grounding operation. Figure 2 As shown.

[0055] (5) When it is necessary to remove the grounding wire, the device first opens the upper phase grounding mechanism and starts to unwind the insulating traction rope 104 and retract the second telescopic rod 1023. Then, the middle phase grounding mechanism is opened in sequence, and the device slowly descends while retracting the first telescopic rod 1022. Finally, the lower phase grounding mechanism is opened, so that the entire device slowly descends.

[0056] (6) After the device is taken offline, the hanging point device 103 and the insulated traction rope 104 are retrieved.
