[0039] In order to have a clearer understanding of the technical features, purposes and effects of the utility model, the specific implementation of the utility model is now described with reference to the accompanying drawings. The same reference numerals in the drawings represent components with the same structure or similar structures but the same functions.

[0040] In this article, "schematic" means "serving as an example, instance or illustration", and any diagram or implementation described as "schematic" in this article should not be interpreted as a more preferred or more advantageous technical solution. In order to make the drawings concise, each figure only schematically shows the parts related to the exemplary embodiment, and they do not represent the actual structure and true proportion of the product.

[0041] Figure 1 It is a schematic diagram for explaining the structure of the upper cover and the lower cover of the wire clamp in one embodiment of the utility model. Figure 2 It is a schematic diagram for explaining the structure of a multifunctional overhead cable clamp in one embodiment of the utility model. Figure 1 , 2 As shown, the first aspect of the utility model provides a multifunctional overhead cable clamp, which includes: a clamp upper cover 10, a clamp lower cover 20, a first electromagnet 31, a second electromagnet 32, a first detection magnet 41 and a second detection magnet 42.

[0042] like Figure 1 , 2 As shown, the clamp upper cover 10 has a first extension direction 11. A first buckling surface 12 is included along the first extension direction 11. On the first buckling surface 12, a first detection cavity 13 and a first power extraction cavity 14 are sequentially formed along the first extension direction 11.

[0043] like Figure 1 , 2 As shown, the lower cover 20 of the wire clamp has a second extension direction 21. A second buckling surface 22 is included along the second extension direction 21. On the second buckling surface 22, a second detection cavity 23 and a second power extraction cavity 24 are formed in sequence along the second extension direction 21.

[0044] like Figure 1 ,2 As shown, the first electromagnet 31 is disposed in the first power extraction cavity 14. A first detection magnet 41 is disposed in the first detection cavity 13. A second electromagnet 32 ​​is disposed in the second power extraction cavity 24. A second detection magnet 42 is disposed in the second detection cavity 23.

[0045] Figure 3 It is a schematic diagram for explaining the structure of a multifunctional overhead cable clamp when it is not fastened in one embodiment of the utility model. Figure 4 It is a schematic diagram for explaining the structure of the multifunctional overhead cable clamp when it is not fastened in another embodiment of the utility model.

[0046] Figure 5 It is a schematic diagram for explaining the structure of the multifunctional overhead cable clamp when it is buckled in one embodiment of the utility model. Figure 3 As shown, the lower cover 20 of the wire clamp can be fastened with the upper cover 10 of the wire clamp along the fastening direction A1. Figure 5 As shown in the figure, the first buckling surface 12 is opposite to the second buckling surface 22. Figure 4 As shown, the lower cover 20 of the wire clamp can be fastened with the upper cover 10 of the wire clamp along the fastening direction B1. Figure 5 The buckling method can be adopted in various ways for easy operation.

[0047] like Figure 6 As shown, when the wire clamp lower cover 20 is buckled with the wire clamp upper cover 10, the first electromagnet 31 and the second electromagnet 32 ​​are opposite and can be separated by a cable spacing C1, so that they can be clamped on the outside of the cable 90. The cable spacing C1 can be understood as the distance that can fix the cable. The first detection magnet 41 and the second detection magnet 42 are opposite and can be separated by the cable spacing C1.

[0048] Therefore, when the multifunctional overhead cable clamp of the utility model is used, the clamp upper cover 10 and the clamp lower cover 20 are surrounded and buckled on the outside of the cable 90. When the cable 90 is working, under the action of the internal current, the first electromagnet 31 and the second electromagnet 32 ​​form a closed electromagnetic induction coil to extract the induced current. When inspection is required, the closed coils of the first detection magnet 41 and the second detection magnet 42 can be controlled externally to output the inspection current.

[0049] The utility model integrates the electromagnetic induction power supply and current sampling (detection) functions in an integral structure, and the two parts can work independently and continuously without time sharing. For situations where electromagnetic induction power supply and current sampling are required at the same time, especially for applications using multi-channel power supply and current sampling, the overall size and weight of the product can be reduced, and the installation steps and costs can be reduced. This advantage is more obvious for high-altitude operations on overhead lines.

[0050] like Figure 7 As shown, in one embodiment of the multifunctional overhead cable clamp of the utility model, the multifunctional overhead cable clamp forms a first cable channel 15 on the first buckling surface 12 along the first extension direction 11, which sequentially passes through the first detection cavity 13, the first power extraction cavity 14 and the two ends of the clamp cover 10. The first cable channel 15 is located in the middle of the first buckling surface 12.

[0051] like Figure 7 As shown, a second cable channel 25 is formed on the second buckling surface 22 along the second extension direction 21, which sequentially passes through the second detection cavity 23, the second power extraction cavity 24 and the two ends of the clamp upper cover 10. The second cable channel 25 is located in the middle of the second buckling surface 22. When the clamp lower cover 20 is buckled with the clamp upper cover 10, as shown in FIG. Figure 5 As shown, the first cable channel 15 and the second cable channel 25 can be surrounded into a through cable channel 91. This facilitates the assembly of the cable to be assembled.

[0052] like Figure 7 As shown, in another embodiment of the multifunctional overhead cable clamp of the utility model, a first wire fixing cavity 16 is formed on the first buckling surface 12 along the first extension direction 11, and the first wire fixing cavity 16 is connected to the first detection cavity 13 and the first power extraction cavity 14. A second wire fixing cavity 26 is formed on the second buckling surface 22 along the second extension direction 21, and the second wire fixing cavity 26 is connected to the second detection cavity 23 and the second power extraction cavity 24.

[0053] The multifunctional overhead cable clamp further comprises: a first wire fixing member, which is disposed in the first wire fixing cavity 16. Figure 8 As shown, a second wire fixing member 27 is disposed in the first wire fixing cavity 16. When the wire clamp lower cover 20 can be buckled with the wire clamp upper cover 10, the first wire fixing member can be connected to the second wire fixing member 27. The first wire fixing member and the second wire fixing member 27 have the same structure and are not shown in the figure.

[0054] Therefore, the first wire fixing member and the second wire fixing member 27 can stably fix the cable 90 between the electromagnet cavity and the detection magnet cavity, thereby ensuring that the cable 90 can be in a stable structure during power collection and detection, and reducing the situation where the first electromagnet 31 and the second electromagnet 32, the first detection magnet 41 and the second detection magnet 42 cannot be tightly attached to the outside of the cable 90 due to the inability to maintain a fixed position, thereby improving the stability, durability and accuracy of use.

[0055] like Figure 7As shown, in another embodiment of the multifunctional overhead cable clamp of the utility model, the clamp upper cover 10 and the clamp lower cover 20 are connected by a buckling structure provided on both sides of the first buckling surface 12 or the second buckling surface 22. The extending direction of both sides of the first buckling surface 12 or the second buckling surface 22 is parallel to the first extension direction 11 or the second extension direction 21. This facilitates the installation operation outside the cable 90.

[0056] In another embodiment of the multifunctional overhead cable clamp of the utility model, the clamp cover 10 forms a first side end and a second side end on the first buckling surface 12 perpendicular to the first extension direction 11. The clamp cover forms a first lateral end and a second lateral end on the first buckling surface 12.

[0057] like Figure 5 As shown, the first side end of the upper cover 10 of the wire clamp is rotated to the first side end of the lower cover 20 of the wire clamp through a rotating shaft 51, so that the second side end can move from a distance position to a locking position relative to the second side end. The axis of the rotating shaft 51 is parallel to the first extension direction 11.

[0058] In another embodiment of the multifunctional overhead cable clamp of the utility model, when the second side end is located at a buckling position relative to the second lateral end, the second side end is buckled and connected with the second lateral end via a buckling structure.

[0059] like Figure 7 As shown, in another embodiment of the multifunctional overhead cable clamp of the utility model, the snap-fit ​​structure includes a snap-fit ​​recess 52 formed on the second side end or the second lateral end, and one or two limiting holes are formed on the inner surface of the snap-fit ​​recess 52 along the first extension direction 11.

[0060] like Figure 7 As shown, a snap-fitting protrusion 53 corresponding to the shape of the snap-fitting recess 52 is formed on the second lateral end or the second side end, and a limiting protrusion is provided on the snap-fitting protrusion 53 along the first extension direction 11, so that when the snap-fitting recess 52 is snapped, the limiting protrusion can be located in the limiting hole.

[0061] like Figure 2 As shown, in another embodiment of the multifunctional overhead cable clamp of the utility model, the first electromagnet 31 is assembled in the first electromagnet cavity 14 through a first electromagnet core fixing sleeve 33. The first detection magnet 41 is assembled in the first detection cavity 13 through a first detection core fixing sleeve 43.

[0062] like Figure 2 As shown, the second electromagnet 32 ​​is mounted in the second electromagnet cavity 24 through a second electromagnet core fixing sleeve 34. The second detection magnet 42 is mounted in the second detection cavity 23 through a second detection magnet core fixing sleeve 44.

[0063] The first electromagnetic core fixing sleeve 33, the first detection core fixing sleeve 43, the second electromagnetic core fixing sleeve 34 and the second detection core fixing sleeve 44 can be made of insulating elastic materials such as rubber, which can effectively fix the electromagnetic core and the detection magnet while ensuring insulation from the shell.

[0064] At the same time, it can also ensure that the power-taking ring and the detection magnetic ring are flexibly supported by the first electromagnetic core fixing sleeve 33, the first detection magnetic core fixing sleeve 43, the second electromagnetic core fixing sleeve 34 and the second detection magnetic core fixing sleeve 44 when in use. Even if the cable fixed thereto vibrates, the magnetic core fixing sleeve can reduce shock to the cable, thereby preventing the cable from being detached from the multifunctional overhead cable clamp of the utility model due to vibration, thereby ensuring a firm and stable installation structure.

[0065] In another embodiment of the multifunctional overhead cable clamp of the utility model, it further includes: a first cable channel fixing sleeve 35 and a second cable channel fixing sleeve 36 .

[0066] The first cable channel fixing sleeve 35 is fixedly connected or integrally formed with the first detection core fixing sleeve 43 and / or the first electromagnetic core fixing sleeve 33 and is located at a position where the first detection core fixing sleeve 43 or the first electromagnetic core fixing sleeve 33 can face the end of the cable channel.

[0067] The second cable channel fixing sleeve 36 is fixedly connected or integrally formed with the second detection core fixing sleeve 44 and / or the second electromagnetic core fixing sleeve 34 and is located at a position where the second detection core fixing sleeve 44 or the second electromagnetic core fixing sleeve 34 can face the end of the cable channel.

[0068] This reduces the wear of the cables on both ends of the utility model multifunctional overhead cable clamp, and reduces the force on the outside of the cable at both ends, thereby avoiding wear or breakage of the cables at both ends. It can also effectively avoid damage to the cable surface caused by burrs on the edges of the upper cover and the lower cover of the clamp during processing.

[0069] like Figure 1 , 2 As shown, in another embodiment of the multifunctional overhead cable clamp of the utility model, the first electromagnet 31, the first detection magnet 41, the second electromagnet 32, and the second detection magnet 42 are semi-annular.

[0070] When the lower cover 20 of the wire clamp is buckled with the upper cover 10 of the wire clamp, the first electromagnet 31 and the second electromagnet 32 ​​can form an electromagnet ring. The distance in the middle of the electromagnet ring corresponds to the diameter of the overhead cable. The first detection magnet 41 and the second detection magnet 42 can form a detection magnetic ring. The distance in the middle of the detection magnetic ring corresponds to the diameter of the overhead cable.

[0071] In another embodiment of the multifunctional overhead cable clamp of the utility model, a power-taking groove is formed around the annular center of the first electromagnet 31 and / or the second electromagnet 32 ​​in the outer circumferential direction of the first electromagnet 31 and / or the second electromagnet 32. A semi-annular protrusion corresponding to the power-taking groove is formed inside the first electromagnet core fixing sleeve 33 and / or the second electromagnet core fixing sleeve 34 so that the semi-annular protrusion can be assembled in the power-taking groove.

[0072] A detection groove is formed around the annular center of the first detection magnet 41 and / or the second detection magnet 42 in the outer circumference direction of the first detection magnet 41 and / or the second detection magnet 42. A semi-annular protrusion corresponding to the detection groove is formed inside the first detection magnetic core fixing sleeve 43 and / or the second detection magnetic core fixing sleeve 44 so that the semi-annular protrusion can be assembled in the detection groove. This is closer to the standard magnet shape, and is easier to process and fix to the outside of the cable.

[0073] like Figure 6 As shown, in another embodiment of the multifunctional overhead cable clamp of the utility model, the semi-circular first electromagnet 31, the first detection magnet 41, the second electromagnet 32, and the second detection magnet 42 extend one or more elastic protrusions 81 toward the middle of the ring, so as to fix the outside of the cable more stably.

[0074] like Fig. 9 As shown, the second aspect of the utility model provides a multifunctional overhead cable spacer, which includes: a spacer frame 71 and four multifunctional overhead cable clamps 81, 82, 83 and 84 of the utility model. The spacer frame 71 has a support surface 72. The multifunctional overhead cable clamps are connected to the spacer frame and are spaced or evenly arranged on the outer circumference of the spacer frame. The first extension direction 11 of the multifunctional overhead cable clamp is perpendicular to the support surface.

[0075] Thus, the four multifunctional overhead cable clamps 81, 82, 83 and 84 are connected to the cables 91, 92, 93 and 94 respectively, playing the role of power supply and detection.

[0076] It should be understood that although this specification is described according to various implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.

[0077] The series of detailed descriptions listed above are only specific descriptions of feasible implementation methods of the utility model. They are not intended to limit the protection scope of the utility model. Any equivalent implementation methods or changes that do not deviate from the technical spirit of the utility model should be included in the protection scope of the utility model.
