[0002] During the power outage inspection and repair of the transmission line, we need to install three-phase short-circuit grounding wires on both sides of the line inspection and repair section to meet the safety requirements of working in the closed grounding wire. The grounding wire installed on the 35kV transmission line is a three-phase short-circuit grounding wire of the combined phase type. This kind of grounding wire weighs fifty or sixty kilograms. Most of the transmission lines are deep in the mountains, and the transportation process is extremely inconvenient. It is time-consuming and laborious to wind the grounding wire, and it requires three people to cooperate to complete it. It also requires two people to open it. It is even more time-consuming and laborious during the installation process. Because the grounding wire itself is relatively heavy, it is very inconvenient during the installation process. People with less strength have problems hanging the whole set of grounding wires on the pole tower. In addition, when there is a small wind during the installation, it is even more problematic for people to hang the whole set of grounding wires on the pole tower. This makes it very laborious for high-altitude operators, which increases the risk of high-altitude operators. Summary of the invention

DETAILED DESCRIPTION

[0028] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0029] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0030] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0031] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0032] Example 1, reference Figure 1 to Figure 2 , which is the first embodiment of the present invention, provides a grounding wire connecting device, including a wire clamp body 100, the wire clamp body 100 is used to connect a cross arm; a crimping mechanism 200, including a first crimping tube 201 arranged on the wire clamp body 100 and a connecting assembly 202 connected to the first crimping tube 201, the first crimping tube 201 is connected to the metal cable through the connecting assembly 202, and the first crimping tube 201 is provided with multiple groups.

[0033] It should be noted that the number of the first crimping tubes 201 is greater than or equal to 1, and can be set according to actual use and the size of the wire clamp body 100 .

[0034] Specifically, it also includes a fixing mechanism 300 , which is disposed on the wire clamp body 100 , and is used to connect the wire clamp body 100 with the cross arm.

[0035] Among them, a limiting ring 202c is provided at the end of the second crimping tube 202b, and the limiting ring 202c divides the second crimping tube 202b into a plug-in portion 202b-1 and a connecting portion 202b-2; the length of the plug-in portion 202b-1 is greater than the length of the connecting portion 202b-2, the plug-in portion 202b-1 is hollow, and the connecting portion 202b-2 is solid, the plug-in portion 202b-1 is used to connect with the metal cable, and the connecting portion 202b-2 is used to connect with the connecting column 202a. It should be noted that the connecting column can be a connecting nut, and the connecting column is mainly used to connect the first crimping tube and the second crimping tube.

[0036] Furthermore, the wire clamp body 100 is in a “C” shape, a through hole is provided on the wire clamp body 100, and the pushing member 301 passes through the through hole.

[0037] Furthermore, the fixing mechanism 300 includes a pushing member 301 and a contact member 302. The pushing member 301 includes a stud 301a and a knob 301b. The stud 301a passes through the through hole. The contact member 302 is used to abut against the cross arm. When the contact member 302 abuts against the cross arm, the relative position of the wire clamp body 100 and the cross arm is fixed.

[0038] Furthermore, a connecting component 202 is plugged into the end of the first crimping tube 201, and the number of the connecting components 202 is the same as that of the first crimping tube 201. It is worth noting that the advantage of plugging the connecting component 202 into the first crimping tube 201 is that it is easy to assemble, which shortens the assembly time and helps save labor hours. When the metal cable becomes "twisted" during the installation process, the "twisted" shape of the metal cable can be released by rotating the wire clamp body 100.

[0039] Furthermore, the connection assembly 202 includes a connection column 202a and a second compression tube 202b. The connection column 202a is used to connect the first compression tube 201 and the second compression tube 202b. The second compression tube 202b is made of a deformable metal material.

[0040] Example 2, reference Figures 4 to 5 This embodiment is different from the first embodiment in that a connecting assembly 202 is threadedly connected to the end of the first crimping tube 201, and the number of the connecting assembly 202 is the same as that of the first crimping tube 201. It is worth noting that the advantage of the threaded connection between the connecting assembly 202 and the first crimping tube 201 is that during assembly, the metal cable in the first crimping tube 201 may be rotated into a twisted shape, while in actual use, the metal cable cannot be "twisted". At this time, rotating the connecting assembly 202 can release the "twisted shape" of the metal cable.

[0041] Further, the fixing mechanism 300 includes a pusher 301, a contact member 302 and a support member 303. The pusher 301 includes a stud 301a and a knob 301b. The stud 301a passes through the through hole. The contact member 302 is used to conflict with the cross arm. When the contact member 302 conflicts with the cross arm, the relative position of the wire clamp body 100 and the cross arm is fixed.

[0042] It should be noted that the contact piece 302 can be a resistance block with a smooth surface, which abuts against the cross arm under the force of the stud 301a. The contact piece 302 can also be a resistance block with an uneven surface, which is used to increase the friction between the resistance block and the cross arm and reduce the displacement between the resistance block and the cross arm.

[0043] The support member 303 is disposed between the contact member 302 and the wire clamp body 100. The support member 303 has elastic force. The support member 303 is used to push the contact member 302 toward the cross arm direction. The support member 303 is used to reduce the looseness between the contact member 302 and the cross arm. It is worth noting that the support member 303 is an elastic object with supporting force such as a spring or an elastic telescopic rod. Taking the spring as an example, one end of the spring is fixedly connected to the wire clamp body 100, and the other end of the spring is fixedly connected to the end of the support member 303. The stud 301a runs through the spring.

[0044] Alternatively, springs are arranged on both sides of the stud 301a, one end of the spring is fixedly connected to the wire clamp body 100, and the other end of the spring is fixedly connected to the end of the support member 303. The support member 303 in this embodiment can reduce the displacement of the stud 301a and the wire clamp body 100 through its elastic properties, thereby increasing the gap between the contact member 302 and the cross arm.

[0045] The rest of the structure is the same as that of Example 1.

[0046] Example 3, reference Figures 4 to 5 This embodiment is different from the above embodiments in that: there is a third connection method between the connecting component 202 and the first crimping tube 201, such as a convex ring is provided on the inner wall of one end of the connecting column 202a, and a concave ring groove is provided on the outer wall of the first crimping tube 201, the convex ring and the concave ring groove are engaged with each other, and the other end of the connecting column 202a can be connected to the second crimping tube 202b by plugging, or a threaded groove is provided on the inner wall of the connecting column 202a, so that the other end of the connecting column 202a is connected to the second crimping tube 202b by threading.

[0047] It should be noted that when the other end of the connecting column 202a is connected to the second crimping tube 202b by plugging, an elastic buckle can be provided to ensure that it can be automatically locked after plugging to prevent accidental falling off.

[0048] The rest of the structure is the same as that of Example 2.

[0049] Operation process: First, the operator inserts the metal cable into the plug-in portion 202b-1 of the second crimping tube 202b until the end of the metal cable moves to the limit ring 202c. This step ensures the correct positioning of the metal cable and lays the foundation for subsequent fixation. Then, the plug-in portion 202b-1 is squeezed and deformed by special tools or manual operation, so that the metal cable is firmly fixed to the inner wall of the plug-in portion 202b-1. This improvement not only improves the stability of the connection, but also reduces the safety hazards caused by loose cables.

[0050] Next, the second crimping tube 202b is connected to the connecting post 202a to ensure a firm connection between the metal cable and the first crimping tube 201. Then, the connecting post 202a is connected to the first crimping tube 201 to further ensure a stable connection of the metal cable. These two steps achieve a stable connection between the metal cable and the wire clamp body 100 through the reasonable design of the connecting assembly 202, and enhance the carrying capacity of the grounding wire.

[0051] Subsequently, the wire clamp body 100 is fixed on the cross arm, and the relative positions of the wire clamp body 100 and the cross arm are fixed by the pusher 301 and the contact member 302 contacting the cross arm. This step realizes the fast and stable connection between the wire clamp body 100 and the cross arm through the interaction between the pusher 301 and the contact member 302 of the fixing mechanism 300, greatly reducing the installation time and improving the reliability of the grounding wire.

[0052] Finally, by rotating the knob 301b, the stud 301a moves toward the contact piece 302, so that the contact piece 302 is firmly connected to the cross arm, and the installation of the grounding wire is completed. When disassembling, the top block and the cross arm are quickly released by operating the knob 301b in the reverse direction, so that the grounding wire can be quickly disassembled. This design not only simplifies the installation and disassembly process, but also reduces the labor intensity of the operator and improves work efficiency.
