Description

Technical Field

[0001] This invention relates to the field of power equipment technology, and in particular to a complete set of conductor grounding devices. Background Technology

[0002] Grounding wires are an essential safety tool for electrical work. Installing grounding wires acts as a safety barrier for maintenance personnel, preventing injury from sudden power surges. However, in actual electrical maintenance work, installing and removing grounding wires is one of the most dangerous operations.

[0003] In the existing technology, the streets of some small towns are relatively narrow, and large equipment such as power maintenance vehicles cannot easily enter due to space limitations when carrying out line maintenance. Therefore, when installing low-voltage grounding wires in these areas, maintenance personnel need to climb ladders, wear insulated gloves, and strip the low-voltage conductors at high altitudes to expose the conductor cores before manually installing the grounding wires. This wastes time, affects work efficiency, and is also extremely inconvenient for maintenance personnel to perform high-altitude stripping operations in narrow streets. Summary of the Invention

[0004] The purpose of this invention is to provide a complete set of conductor grounding devices, which can effectively speed up the installation efficiency of grounding wires and ensure the safety of maintenance personnel.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] A conductor grounding assembly is used for grounding a conductor, the conductor including a transmission end conductor and a power supply end conductor, the conductor grounding assembly comprising:

[0007] A conductive component includes a conductive plate and a first conductive head disposed on the conductive plate. A first end of the conductive plate is electrically connected to the power transmission end wire through the first conductive head, and a second end of the conductive plate is electrically connected to the power supply end wire.

[0008] A grounding assembly includes a fixed rod and a telescopic rod that can extend and retract from the fixed rod. Both the fixed rod and the telescopic rod are made of insulating material. The telescopic rod is provided with a snap-fit ​​groove and a grounding conductor. The snap-fit ​​groove is used to fix a grounding wire. After the conductive end of the grounding wire passes through the snap-fit ​​groove, it can contact and connect with the grounding conductor. Furthermore, when the telescopic rod rises relative to the fixed rod, the grounding conductor can contact and connect with the first conductive head.

[0009] Optionally, the conductive plate is further provided with a second conductive head, and the second end of the conductive plate is electrically connected to the power supply terminal wire through the second conductive head, and the power supply terminal wire can be electrically connected to an external power source through the second conductive head.

[0010] Optionally, the first conductive head has a first conductive cavity and a first insertion hole communicating with the first conductive cavity. The grounding head is spherical in shape. After passing through the first insertion hole, the grounding head can be located in the first conductive cavity and closely attached to the inner wall of the first conductive cavity.

[0011] Optionally, the first conductive head is made of an elastic material, and the diameter of the first socket is smaller than the diameter of the grounding conductor.

[0012] Optionally, the first conductive head is connected to a first conductive connector, and the power transmission end wire is electrically connected to the first conductive connector through a first conductive connecting piece.

[0013] Optionally, the first conductive connector is further provided with a first clamping member, which can press the first conductive connecting piece onto the first conductive head.

[0014] Optionally, a second conductive connector is connected to the second conductive head, and the power supply terminal wire is electrically connected to the second conductive connector through a second conductive connecting piece.

[0015] Optionally, the second conductive connector is further provided with a second clamping member, which can press the second conductive connecting piece onto the second conductive head.

[0016] Optionally, the telescopic rod has a telescopic groove, and the fixed rod is partially inserted into the telescopic groove. The fixed rod has an external thread, and the inner sidewall of the telescopic groove has an internal thread that matches and connects with the external thread. The telescopic rod can extend or retract relative to the fixed rod by rotating relative to the fixed rod.

[0017] Optionally, the conductive plate is made of copper.

[0018] Beneficial effects:

[0019] The conductor grounding device provided by this invention has a conductive plate whose first end is electrically connected to the transmission end conductor via a first conductive head, and whose second end is electrically connected to the power supply end conductor. The conductive plate is connected in series with the conductor, allowing the current in the conductor to flow sequentially through the transmission end conductor, the conductive plate, and the power supply end conductor. During grounding operations, maintenance personnel wearing insulated gloves place the fixed rod on a horizontal surface. They then insert the conductive end of the grounding wire through the locking groove and connect it to the grounding conductor. The inserted portion of the grounding wire effectively engages with the locking groove. Next, the maintenance personnel control the telescopic rod to extend relative to the fixed rod, raising the telescopic rod until the grounding conductor on the telescopic rod contacts the first conductive head. At this point, the current in the transmission end conductor flows sequentially through the first conductive head, the grounding conductor, and the grounding wire into the ground, thus completing the conductor grounding. The entire process is simple to operate, eliminating the need for maintenance personnel to climb ladders for wiring, effectively ensuring their safety, and significantly improving the efficiency of grounding wire installation.

[0034] Example 1

[0035] This embodiment provides a complete set of conductor grounding devices for grounding conductors. The conductors include a transmission end conductor 310 and a power supply end conductor 320. The transmission end conductor 310 is connected to remote power transmission equipment, and the power supply end conductor 320 is connected to each terminal user. The current transmitted by the remote power transmission equipment flows sequentially through the transmission end conductor 310 and the power supply end conductor 320 before entering each terminal user.

[0036] Reference Figures 1 to 3As shown, the conductor grounding assembly includes a conductive component and a grounding component. The conductive component includes a conductive plate 110 and a first conductive head 120 disposed on the conductive plate 110. The first end of the conductive plate 110 is electrically connected to the power transmission end conductor 310 through the first conductive head 120, and the second end of the conductive plate 110 is electrically connected to the power supply end conductor 320. The grounding component includes a fixed rod 210 and a telescopic rod 220 that can extend and retract from the fixed rod 210. Both the fixed rod 210 and the telescopic rod 220 are made of insulating material. The telescopic rod 220 is provided with a snap-fit ​​groove 221 and a grounding guide head 222. The snap-fit ​​groove 221 is used to fix the grounding wire 400. After the conductive end of the grounding wire 400 passes through the snap-fit ​​groove 221, it can contact and connect with the grounding guide head 222. Furthermore, when the telescopic rod 220 rises relative to the fixed rod 210, the grounding guide head 222 can contact and connect with the first conductive head 120.

[0037] In this embodiment, the first end of the conductive plate 110 is electrically connected to the power transmission end wire 310 through the first conductive head 120, and the second end of the conductive plate 110 is electrically connected to the power supply end wire 320. That is, the conductive plate 110 is connected in series on the wire, and the current in the wire can flow sequentially through the power transmission end wire 310, the conductive plate 110, and the power supply end wire 320. When performing grounding operations, maintenance personnel wear insulated gloves, place the fixed rod 210 on a horizontal surface, and then pass the conductive end of the grounding wire 400 through the locking groove 221 and connect it to the grounding conductor 222. The part of the grounding wire 400 that passes through the locking groove 221 can effectively lock into place. Next, the maintenance personnel control the telescopic rod 220 to extend relative to the fixed rod 210, raising the telescopic rod 220 until the grounding conductor 222 contacts and connects with the first conductive head 120. At this time, the current in the transmission end conductor 310 will flow into the ground sequentially through the first conductive head 120, the grounding conductor 222, and the grounding wire 400, thereby completing the conductor grounding work. The whole process is simple to operate, and maintenance personnel do not need to climb ladders to connect the wires, effectively ensuring the safety of maintenance personnel and effectively improving the efficiency of grounding wire installation.

[0038] In this embodiment, the conductive end of the grounding wire 400 can be inserted into the grounding head 222 or bound to the grounding head 222; no further limitations are imposed here. In this embodiment, the conductive plate 110 is made of steel.

[0039] In this embodiment, reference continues to be made to... Figures 1 to 3As shown, the first conductive head 120 has a first conductive cavity 121 and a first insertion hole 122 communicating with the first conductive cavity 121. The grounding head 222 is spherical in shape. After passing through the first insertion hole 122, the grounding head 222 can be located inside the first conductive cavity 121 and closely attached to the inner wall of the first conductive cavity 121. After passing through the first insertion hole 122, the grounding head 222 extends into the first conductive cavity 121 and closely attaches to the inner wall of the first conductive cavity 121, thereby increasing the effective contact area between the grounding head 222 and the first conductive head 120, further ensuring the conduction effect of current.

[0040] Furthermore, the first conductive head 120 is made of an elastic material, and the diameter of the first socket 122 is smaller than the diameter of the grounding head 222. With this configuration, when the grounding head 222 passes through the first socket 122, the first socket 122 expands outward due to elasticity, allowing the grounding head 222 to enter the first conductive cavity 121. After the grounding head 222 enters, the first socket 122 retracts back to its original size due to elasticity, thus completely enclosing the grounding head 222 and further ensuring close contact between the grounding head 222 and the first conductive head 120.

[0041] Optionally, the first conductive head 120 is configured as a spring conductive coil with elasticity.

[0042] Furthermore, a first conductive connector 140 is connected to the first conductive head 120, and the power transmission end wire 310 is electrically connected to the first conductive connector 140 through a first conductive connecting piece 150. In this embodiment, the first conductive connecting piece 150 is preferably configured as a wire lug, which is fitted onto the first conductive connector 140 through a connection hole it has.

[0043] Furthermore, a first clamping member 160 is also fitted onto the first conductive connector 140, which can press the first conductive connecting piece 150 onto the first conductive head 120. In this embodiment, the first clamping member 160 has a threaded hole, and the first conductive connector 140 is provided with an external thread that matches the threaded hole. The first clamping member 160 is fitted onto the first conductive connector 140 and screwed on, so that the first clamping member 160 can move downward and reliably press against the first conductive connecting piece 150, thereby pressing the first conductive connecting piece 150 onto the first conductive head 120. Preferably, the first clamping member 160 is a nut.

[0044] Continue to refer to Figures 1 to 3As shown, a second conductive head 130 is also provided on the conductive plate 110. The second end of the conductive plate 110 is electrically connected to the power supply wire 320 through the second conductive head 130. The power supply wire 320 can be electrically connected to an external power source through the second conductive head 130. In this embodiment, after the grounding work is completed, the current in the transmission wire 310 will flow into the ground sequentially through the first conductive head 120, the grounding conductor 222, and the grounding wire 400, and will no longer flow into the power supply wire 320. This would affect the power supply to end users during grounding maintenance. By setting the second conductive head 130, the second conductive head 130 can be electrically connected to an external power source. The current output by the external power source can flow sequentially through the second conductive head 130 and the power supply wire 320 to each end user, so as to ensure that end users can use power normally during line maintenance.

[0045] Optionally, the second conductive head 130 has a second conductive cavity 131 and a second socket 132 communicating with the second conductive cavity 131, so that the connection terminal of the external power supply can be reliably connected. The specific connection process is similar to the description of the first conductive cavity 121 and the first socket 122 in the above content, and will not be repeated here.

[0046] In this embodiment, a second conductive connector 170 is connected to the second conductive head 130, and the power supply wire 320 is electrically connected to the second conductive connector 170 through a second conductive connecting piece 180. In this embodiment, the second conductive connecting piece 180 is preferably also configured as a wire lug, which is fitted onto the second conductive connector 170 through a connection hole it has.

[0047] A second clamping member 190 is also fitted onto the second conductive connector 170, which can press the second conductive connecting piece 180 onto the second conductive head 130. In this embodiment, the second clamping member 190 has a threaded hole, and the second conductive connector 170 has an external thread that matches the threaded hole. The second clamping member 190 is fitted onto the second conductive connector 170 and screwed on, so that the second clamping member 190 can move downward and reliably press against the second conductive connecting piece 180, thereby pressing the second conductive connecting piece 180 onto the second conductive head 130. Preferably, the second clamping member 190 is also a nut.

[0048] Continue to refer to Figures 1 to 3As shown, the telescopic rod 220 has a telescopic groove, and the fixed rod 210 is partially inserted into the telescopic groove. The fixed rod 210 has an external thread, and the inner wall of the telescopic groove has an internal thread that matches the external thread. The telescopic rod 220 can extend or retract relative to the fixed rod 210 by rotating relative to the fixed rod 210. This arrangement allows the telescopic rod 220 and the fixed rod 210 to form a screw-nut structure, thereby reliably and conveniently realizing the raising and lowering action of the telescopic rod 220. The structure is simple and the operation is convenient.

[0049] Example 2

[0050] Reference Figure 4 As shown, the difference between this embodiment and Embodiment 1 is that it also includes a linear servo module. Specifically, the linear servo module includes a slide rail 510 and a sliding drive component 520 slidably connected to the slide rail 510, wherein the slide rail 510 is vertically disposed on the fixed rod 210, and the sliding drive component 520 is fixed to the telescopic rod 220.

[0051] In this embodiment, the sliding drive component 520 can automatically slide relative to the slide rail 510. With this configuration, when the telescopic rod 220 is raised or lowered, the sliding drive component 520 can slide relative to the slide rail 510, thereby driving the telescopic rod 220 to slide and extend / retract relative to the fixed rod 210, thereby realizing automatic control of the telescopic rod 220's extension and retraction operation, making the overall control process of the device more automated and intelligent.

[0052] The working principle and process of the linear servo module are existing technologies and will not be elaborated on here.

[0053] In other embodiments, the telescopic rod 220 can also be extended and retracted by a drive component such as a drive cylinder. Alternatively, the fixed rod 210 and the telescopic rod 220 can be directly configured as an electric push rod structure, which can also make the control process more automated.

[0054] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
