[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0018] As Figures 1 - 4 shown, it is the first embodiment of the flexible power supply track structure of the present invention.

[0019] In this embodiment of the flexible power supply track structure, it includes: multiple chain link assemblies 1, and the multiple chain link assemblies 1 are connected in sequence to form a chain link T. At the head and tail ends of the chain link T, there are respectively provided matching locking members S; the chain link assembly 1 includes: a flame-retardant housing 11, a first metal sheet 12 installed in the flame-retardant housing 11, and a second metal sheet 13 installed in the flame-retardant housing 11; one side of the flame-retardant housing 11 is provided with a first connection end 111, and the opposite side of the flame-retardant housing 11 is provided with a second connection end 112; the structures of the first connection end 111 and the second connection end 112 are adapted and clamped hinge structures, and the multiple chain link assemblies 1 are connected in sequence to form a chain link T with adjustable bending degree through the adaptation and clamping of the first connection end 111 and the second connection end 112 of adjacent two chain link assemblies.

[0020] Among them, the chain link T is tightly wound around the surface of the high-voltage cable and the accessory F by disassembling and assembling the locking fastener S. A plurality of first metal sheets 12 in the sequentially connected chain link assemblies 1 are connected to form an electrical path, and a plurality of second metal sheets 13 in the sequentially connected chain link assemblies 1 are connected to form an electrical path, so as to make the chain link T fit on the surface of the high-voltage cable and the accessory F and supply power.

[0021] During specific implementation, the structures of multiple chain link assemblies 1 are the same. In this way, the length of the chain link T can be changed by increasing or decreasing the number of chain link assemblies 1. For example: when the diameter dimensions of the high-voltage cable and the accessory F are relatively large, the number of chain link assemblies 1 can be increased so that multiple chain link assemblies 1 can fit on the surface of the high-voltage cable and the accessory F after being assembled.

[0022] The single length of the chain link assembly 1 is 1 cm - 3 cm, which can be adjusted according to actual needs. The chain link assembly 1 includes: a flame-retardant outer shell 11, a first metal sheet 12, and a second metal sheet 13. The flame-retardant outer shell 11 is made of a flexible insulating material, which is a plastic molding added with a flame retardant in this embodiment, and the material has slight flexibility.

[0023] Furthermore, a first connection end 111 is provided on one side of the flame-retardant outer shell 11, and a second connection end 112 is provided on the opposite side of the flame-retardant outer shell 11. In this embodiment, the structures of the first connection end 111 and the second connection end 112 are an articulated structure with matching clamping. By the matching clamping of the first connection end 111 and the second connection end 112 of adjacent two chain link assemblies 1, multiple chain link assemblies 1 are sequentially connected to form a chain link T with adjustable bending degree.

[0024] Preferably, the first connection end 111 is a convex plug structure, and the second connection end 112 is a slot cavity structure. The external dimensions of the convex plug structure are adapted to the internal dimensions of the slot cavity structure, so as to enable the pluggable connection of adjacent two chain link assemblies 1. In this way, the length of the chain link T can be changed by increasing or decreasing the number of chain link assemblies 1.

[0025] Preferably, through holes V are respectively provided at the positions of the convex plug structure and the slot cavity structure, and a detachable connection rod 2 is connected to the through hole V.

[0026] Furthermore, an assembly hole 113 is provided on the flame-retardant outer shell 11, and a cavity groove a is provided on the first metal sheet 12 or the second metal sheet 13 at a position adapted to the assembly hole 113;

[0027] The flexible power supply track structure further includes: an adsorption magnetic hole part 3, and the adsorption magnetic hole part is correspondingly installed at the positions of the assembly hole 113 and the cavity groove a, wherein: by inserting a power electrode through the adsorption magnetic hole part 3, power is supplied to an external high-voltage cable measurement module fastened on the surface of the high-voltage cable and the accessory.

[0028] In this embodiment, the adsorption magnetic hole component 3 is in an annular shape. The functions of setting the adsorption magnetic hole component 3 are as follows: First, it serves as a power supply jack for the external high-voltage cable measurement module, and the power electrode can be inserted here, thereby playing the role of supplying power to the external measurement module. Second, it serves as the connection framework of the chain link. When no other device is inserted, the two chain links T can be adsorbed by the magnetic attraction of the adsorption magnetic hole component 3, playing the role of fixing the chain link T.

[0029] It can be understood that the flexible power supply track structure includes multiple groups of chain links T. The multiple groups of chain links T placed side by side are fixedly adsorbed through the adsorption magnetic hole component 3, and the multiple groups of chain links T placed side by side share the positive and negative electrodes.

[0030] Furthermore, the first metal sheet 12 and the second metal sheet 13 are respectively made of materials with a certain degree of ductility and can be slightly bent synchronously with the flame-retardant housing 11. The functions of such a setting are as follows: The first metal sheet 12 and the second metal sheet 13 are copper sheets. The copper sheets for conducting electricity have a certain degree of ductility and can be slightly bent synchronously with the flame-retardant housing 11. When a single chain link T is bent under force, it can fit on the different-diameter curved surfaces of the cable and its accessories, further increasing the fastening property, and thus ensuring that while the chain link guarantees the electrical function, its fitting degree with the different-diameter cable surface is improved.

[0031] In this embodiment, multiple first metal sheets 12 in the sequentially connected chain link assembly 1 are connected to form an electrical path, and multiple second metal sheets 13 in the sequentially connected chain link assembly 1 are connected to form an electrical path. The functions of such a setting are as follows: The voltage of the high-voltage cable measurement module is mostly low-voltage direct current such as 5V and 10V. The structure assembled by the flame-retardant housing 11, the first metal sheet 12, and the second metal sheet 13 forms a power supply module, thereby realizing the functions of voltage regulation and power quality regulation of electric energy. After adjacent two chain link assemblies 1 are connected, an overall chain link T is formed, and thus a power supply can be distributed to several chain links, achieving the purpose of intensive power supply.

[0032] When the flexible power supply track structure in this embodiment is specifically implemented, the chain link T is locked and wound around the surface of the high-voltage cable and its accessories F through the dismountable lock fastener S. The structures of the first connection end 111 and the second connection end 112 are articulated structures that are adaptively clamped, and have flexible operability for the different-diameter curved surfaces of the high-voltage cable and its accessories. As the number of measurement devices increases, the length of the chain link can be flexibly adjusted to achieve the functions of power supply and fixation.

[0033] The flexible power supply track structure has a function of slightly adjustable curvature. Through the flexible molding of the chain link and the combination of the internally placed ductile copper strip, the curvature of the chain link can be adjusted to achieve a high degree of fitting with the different-diameter cable and its accessories, facilitating the fixation of the chain and the data accuracy of the measurement module.

[0034] In addition, multiple first metal sheets 12 in the sequentially connected chain link components 1 are connected in sequence to form an electrical path, and multiple second metal sheets 13 in the sequentially connected chain link components 1 are connected in sequence to form an electrical path, achieving the unexpected technical effect of synchronously realizing power supply and connection. When multiple chain links are placed side by side, the positive and negative poles can be shared.

[0035] Implementing a flexible power supply track structure of the present invention has the following beneficial effects: The flexible power supply track structure includes: multiple chain link components, and the multiple chain link components are sequentially connected to form a chain link, and fitting fasteners are respectively provided at the head and tail ends of the chain link; The chain link component includes: a flame-retardant outer shell, a first metal sheet installed in the flame-retardant outer shell, a second metal sheet installed in the flame-retardant outer shell, and a fastening component for fastening the first metal sheet, the second metal sheet, and the flame-retardant outer shell; A first connection end is provided on one side of the flame-retardant outer shell, and a second connection end is provided on the opposite side of the flame-retardant outer shell; The structures of the first connection end and the second connection end are articulated structures that are adapted to be clamped. The multiple chain link components are sequentially connected to form a chain link with an adjustable curvature through the fitting clamping of the first connection end and the second connection end of adjacent two chain link components, wherein: The chain link is locked and wound around the surface of the high-voltage cable and accessories by disassembling and assembling the fasteners. Multiple first metal sheets in the sequentially connected chain link components are connected in sequence to form an electrical path, and multiple second metal sheets in the sequentially connected chain link components are connected in sequence to form an electrical path, so as to make the chain link fit on the surface of the high-voltage cable and accessories and supply power, and the length of the power supply track can be increased or decreased according to requirements and flexibly fit on the surface of the cable and accessories, having the power supply function; The structure is reasonable and the cost is easy to control.
