[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] The embodiment of the present invention provides a non-stop multifunctional wire clamp for a distribution network, such as Figure 1 and Figure 2 As shown, the distribution network non-stop multifunctional wire clamp includes components such as a basic pressure seat 1, a lifting control mechanism 2, a movable pressure block 3, a limit pressure plate 4 and a grounding hanging ring 5, and each component is made of metal to meet the needs of live working and bypass working; wherein, the basic pressure seat 1 cooperates with the lifting control mechanism 2 and the movable pressure block 3 to form a basic wire clamp structure, so that the distribution network non-stop multifunctional wire clamp is hung on a given cable as a whole; the basic pressure seat 1 cooperates with the limit pressure plate 4 and the grounding hanging ring 5 to form different functional assembly areas, which can not only meet the power diversion grounding during live working, but also meet the temporary replacement of the distribution line for power supply by the transfer line during bypass operation.

[0027] like Figure 1 , Figure 2 and Figure 3 As shown, the structure of the basic press seat 1 in this embodiment includes a crimping arc plate 6 at the top, a crimping back plate 7 at the middle and a connecting seat body 8 at the bottom. The crimping arc plate 6, the crimping back plate 7 and the connecting seat body 8 are integrally formed to form a basic press seat 1 in a C-shape as a whole. Among them, the crimping arc plate 6 is an arc-shaped plate body, which serves as the fixed side clamp structure of the wire clamp; as a preferred solution of this embodiment, in order to ensure the structural strength of the crimping arc plate 6, a reinforcing rib 11 can be reserved on the outer surface of the crimping arc plate 6 during the machining process of the crimping arc plate 6, and the reinforcing rib 11 is used to improve its structural rigidity.

[0028] like Figure 1 and Figure 2 As shown, the movable pressure block 3 is located in the C-shaped opening of the basic pressure seat 1. The movable pressure block 3 is installed on the connecting seat body 8 of the basic pressure seat 1 through the lifting control mechanism 2. The upper surface of the movable pressure block 3 is a downwardly concave arc surface, which serves as the movable side clamping structure of the wire clamp. The movable pressure block 3 can move vertically relative to the crimping arc plate 6 through the lifting control mechanism 2, and then cooperate with the crimping arc plate 6 to achieve clamping of a given cable.

[0029] like Figure 1 and Figure 2 As shown, the lifting control mechanism 2 in this embodiment includes a top pressing screw 12 and a connecting shaft 13. A threaded hole for matching the top pressing screw 12 is provided on the connecting seat body 8 of the basic pressing seat 1. The top pressing screw 12 vertically passes through the connecting seat body 8 through the threaded hole and is threadedly connected to the connecting seat body 8; to ensure safety, the outer wall of the top pressing screw 12 is coated with an insulating layer as a whole. Figure 1As shown, one end of the connecting shaft 13 is inserted into the top of the top pressing screw 12, and one end of the connecting shaft 13 is connected to the top pressing screw 12 through a bearing in the top pressing screw 12. The other end of the connecting shaft 13 forms a T-shaped block, and the bottom of the movable pressing block 3 forms a T-shaped slot. The other end of the connecting shaft 13 is connected to the movable pressing block 3 through the T-shaped block and the T-shaped slot.

[0030] The working principle of the distribution network non-stop multifunctional wire clamp hung on the established cable as a whole is as follows:

[0031] When the top pressing screw 12 is rotated in the forward direction, since the top pressing screw 12 is threadedly connected to the connecting seat body 8 of the basic pressing seat 1, the top pressing screw 12 drives the limiting pressing plate 4 to move vertically toward the crimping arc plate 6 while rotating, so that the movable pressing block 3 cooperates with the crimping arc plate 6 to clamp the predetermined cable. On the contrary, when the top pressing screw 12 is rotated in the reverse direction, the top pressing screw 12 drives the limiting pressing plate 4 to move vertically away from the crimping arc plate 6, and the predetermined cable can be removed from the distribution network non-stop multifunctional wire clamp.

[0032] Further, as a preferred solution of this embodiment, considering the convenience of rotating the top pressing screw 12, as Figure 1 and Figure 2 As shown, in this embodiment, a drive assembly ring 14 is provided at the end of the top pressure screw 12 away from the connecting shaft 13, which is used to assist the external gun drive through the drive assembly ring 14 to more efficiently and safely clamp the predetermined cable, thereby effectively improving the safety of construction operations during live installation.

[0033] Furthermore, as a preferred solution of this embodiment, considering the stability of the given cable clamp, as Figure 1 and Figure 2 As shown, during the machining process of the crimping arc plate 6, three raised first pressurizing teeth 9 can be evenly spaced on the inner surface of the crimping arc plate 6, and the first pressurizing teeth 9 extend laterally on the inner surface of the crimping arc plate 6; at the same time, during the machining process of the movable pressure block 3, three second pressurizing teeth 10 can be evenly spaced on the arc surface of the upper surface of the movable pressure block 3, and the second pressurizing teeth 10 extend laterally on the upper surface of the movable pressure block 3; the first pressurizing teeth 9 and the second pressurizing teeth 10 correspond one to one, and the first pressurizing teeth 9 cooperate with the second pressurizing teeth 10 to effectively increase the contact pressure with the established cable, thereby ensuring the stability of the wire clamp clamping.

[0034] Compared with the existing wire clamps, the distribution network non-stop multifunctional wire clamp can clamp the lead cable and the grounding hanging ring 5 through the crimping back plate 7 of the basic pressure seat 1 in cooperation with the limiting pressure plate 4, thereby forming different functional assembly areas; the grounding wire can be hung through the grounding hanging ring 5 for live work; the lead cable can be connected to the transfer line for bypass operation, thus solving the problem of single function of the wire clamp structure and poor flexibility and adaptability to complex working scenes.

[0035] Specifically, Figure 3 As shown, in this embodiment, a first angle adjustment limit groove 15 and a first cable crimping groove 16 are provided on the outer side of the crimping back plate 7 in a cross shape; Figure 4 As shown, the limiting pressure plate 4 is provided with a second angle adjustment limiting groove 17 and a second cable crimping groove 18 in a cross shape; Figure 2 As shown in the figure, the crimping back plate 7 is connected to the limiting pressure plate 4 by bolts at the four corners; after the connection, the first angle adjustment limiting groove 15 and the second angle adjustment limiting groove 17 are formed as shown in the figure. Figure 2 As shown in FIG. 1 , the transverse through hole 19 for the grounding ring 5 to pass through, the first cable crimping groove 16 and the second cable crimping groove 18 are formed as shown in FIG. Figure 1 The vertical blind hole 20 for inserting the lead cable end is shown in FIG. Figure 5 As shown, the grounding ring 5 is a rectangular rounded ring structure, and either side of the grounding ring is a locking rod 21 that can pass through the transverse through hole 19.

[0036] When performing live work, the grounding ring 5 is clamped by the crimping back plate 7 of the base press seat 1 in cooperation with the limit plate 4, and the grounding wire is hung through the grounding ring 5, so as to lead the current of the predetermined cable into the ground, effectively ensuring the personal safety of the engineering workers. When performing bypass work, the crimping back plate 7 of the base press seat 1 cooperates with the limit plate 4 to clamp one end of the lead cable, and connect the other end to the transfer line, so as to temporarily replace the distribution line for power supply through the transfer line, so as to realize the power outage maintenance of the high-voltage line that needs maintenance without interrupting the power supply to users.

[0037] Further, as a preferred solution of this embodiment, when performing live work, the grounding ring 5 may need to be adjusted to a certain angle to meet the needs of hanging the grounding wire; for this purpose, in this embodiment, the positioning rod 21 is designed as a multi-prism structure, and the number of facets can be specifically adopted but not limited to four side faces and six side faces, and at the same time, the first angle adjustment limit groove 15 and the second angle adjustment limit groove 17 are processed into a multi-prism groove body, so that the number of inner side walls of the transverse through hole 19 corresponds to the number of outer side walls of the positioning rod 21. In this way, a conversion limit effect is formed between the positioning rod 21 and the corresponding surface of the transverse through hole 19, and the angle of the positioning rod 21 and the overall grounding ring 5 can be effectively adjusted based on the conversion limit effect, and then the positioning rod 21 and the overall grounding ring 5 can be made more stable by means of the limit effect after the angle is adjusted to the right position, so as to avoid the grounding ring 5 from loosening and sliding down due to long-term hanging of the grounding wire, and effectively improve the safety of the operation and its functional practicality.

[0038] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
