Description

Technical Field

[0001] This utility model relates to the field of power facility identification technology, specifically a cable path marking device. Background Technology

[0002] The city is riddled with cables, both underground and overhead. To inspect and repair these cables, you first need to know which cable is which. Therefore, people need to mark the cables.

[0003] In the past, there were two main methods commonly used: The "tag" method involves attaching a small plastic or metal tag with information to the cable. However, these tags are usually simply tied or clipped to the cable. Over time, the straps can age and break, or the clips may not be tight enough. Even slight vibrations or accidental bumps by workers can easily cause the tag to fall off. This is especially problematic in confined or cluttered spaces, where lost tags are very difficult to retrieve.

[0004] The "landmarking" method involves inserting a small stake or affixing a label to the ground above the cable line. This method has more pronounced problems; exposed to wind, sun, and rain, the lettering on the sign quickly becomes blurred or even disappears completely. Furthermore, if it's on a lawn, a lawnmower might remove the sign; on a road, it's easily damaged by vehicles. Utility Model Content

[0005] (a) Technical problems to be solved To address the shortcomings of existing technologies, this utility model provides a cable path marking device that is quick and easy to install by hand, has automatically adjustable locking force, and a long marking life.

[0006] (ii) Technology provider The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A cable path marking device includes a clamping mechanism, a connecting seat, a locking component, and a marking installation part. The clamping mechanism is composed of a first semi-circular clamping arm and a second semi-circular clamping arm, one end of which is hinged through the connecting seat. A return spring is embedded inside the connecting seat, and the two ends of the return spring respectively contact the ends of the clamping arms. A cable limiting groove is provided on the inner side of the clamping arm, and the inner surface of the cable limiting groove is covered with an anti-slip layer made of wear-resistant silicone rubber. The locking component is installed on the free end of the clamping arm and includes a latch and a locking groove. The latch is fixedly connected to the first semi-circular clamping arm through a fixing block. A rotatable shaft is provided on the top of the connecting seat, and a slot is provided on the top of the rotatable shaft. The slot is embedded with a marking installation part, including a replaceable marking plate fixed on the slot.

[0007] The beneficial effects of this utility model are: This cable path marking device employs a spring hinge combined with a magnetic self-locking structure. The operator only needs to press with one hand to open and close the device, which automatically locks upon release. Installation requires no tools, and actual testing shows that a single installation time is reduced to less than a second, significantly reducing the difficulty and time consumption of operations in complex scenarios such as high-altitude locations and manholes. Simultaneously, a triple-protection mechanism ensures stability: the magnetic latch provides instantaneous closure and basic locking force; the clamping mechanism prevents accidental unlocking due to vibration; and the limiting groove, combined with a silicone anti-slip layer, forms an adaptive clamping force, which increases in the reverse direction when the cable is pulled by external forces. The main body of the device integrates a high-brightness reflective strip that meets road traffic reflectivity standards. In nighttime or low-light conditions, it can be quickly identified within a meter using vehicle headlights / flashlights, significantly reducing the risk of accidental injury to maintenance personnel during nighttime inspections and third-party construction. Its overall tensile strength is more than twice that of traditional devices, effectively coping with harsh environments such as strong winds and mechanical vibrations.

[0008] Based on the above technical solution, the present invention can be further improved as follows.

[0009] Preferably, the locking component is a magnetic latch structure, with the latch being a permanent magnet and the locking groove made of ferromagnetic material, and is fixed by magnetic attraction after closing. The magnetic latch provides instantaneous closing and basic locking force, further improving the stability of the lock.

[0010] Preferably, the sign mounting part includes a waterproof transparent cover that covers the outside of the sign and is waterproofed by a sealing ring. This extends the lifespan of the sign in outdoor environments and effectively solves the problem of frequent replacements.

[0011] Preferably, the outer surface of the clamping mechanism is provided with reflective strips made of a fluorescent coating. The main body of the device integrates high-brightness reflective strips, which meet road traffic reflectivity standards and significantly reduce the risk of accidental injury to maintenance personnel during nighttime inspections and to third-party construction workers in low-light or dark environments.
