Description

Technical Field

[0001] This utility model relates to the field of power cable fault alarm technology, specifically an alarm mechanism for power service communication. Background Technology

[0002] The power service communication alarm mechanism is a specialized device designed for the safety monitoring and alarm of power system communication equipment. It can detect abnormal conditions in communication lines in real time, such as line faults, disconnections, or interference. Once an abnormality is detected, it immediately issues an alarm signal to help maintenance personnel take timely measures, ensuring the stability and security of power communication and guaranteeing the normal operation of power transmission and control systems.

[0003] Existing power service communication alarm mechanisms are typically devices that indicate the flow of fault current. This new type of fault indicator can not only detect short-circuit and grounding faults on the line, but also choose to alarm via either a flashing indicator or a light. If the fault occurs at night, it will activate the light alarm; if the fault occurs during the day, it will activate the flashing indicator. When a line fault occurs, patrol personnel can quickly identify the fault section and locate the fault point using the indicator's red alarm display, greatly improving work efficiency, shortening power outage time, and effectively improving power supply reliability. For example, the Lei Yi brand cable fault indicator, model SX-JDX, displays a white window when the cable is running normally. When a short circuit or ground fault occurs, the window will display a red or illuminated indicator. The specific installation method requires placing an insulating rod at the bottom of the installation tool, unscrewing the top pull pin of the alarm mechanism and inserting it into the tool, then snapping the alarm mechanism into the cable. This requires prior preparation of the installation tool and insulating rod, making the installation and use of the alarm mechanism inconvenient. Furthermore, using only the pull pin and V-shaped groove to clamp the cable at a single point during installation provides poor cable clamping, and the alarm mechanism is prone to swaying on the cable when exposed to wind. Therefore, we propose an alarm mechanism for power service communication. Utility Model Content

[0004] The purpose of this invention is to provide an alarm mechanism for power service communication to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an alarm mechanism for power service communication, comprising a housing, an alarm window provided on the top of the housing, a fastener fixedly connected to the bottom of the housing, a V-shaped groove provided on the side wall of the fastener, a pull pin passing through the side wall of the fastener and engaging with the bottom of the V-shaped groove, a rotating assembly provided on the side wall of the housing, and a clamping assembly rotatably connected to the side wall of the rotating assembly.

[0006] Preferably, the rotating assembly includes a side member fixed to the side wall of the housing, a rotating arm rotatably connected to the side wall of the side member, a rotating shaft fixed to one end of the rotating arm, and a locking knob passing through the other end of the rotating arm.

[0007] Preferably, the clamping assembly includes a rotating component rotatably connected to the side wall of the rotating arm, a notch machined in the side wall of the rotating component, a rubber component disposed inside the notch, and a mating opening formed in the side wall of the rubber component.

[0008] Preferably, a stop bar is fixedly connected to the top of the rotating arm, and the stop bar is engaged with the top of the rotating component.

[0009] Preferably, the top of the V-shaped slot is provided with a protrusion, and the top of the protrusion is provided with a compression spring that cooperates with the V-shaped slot.

[0010] Preferably, the outer wall of the rotating shaft is machined with anti-slip texture, and the rotating shaft extends through the top of the side member.

[0011] Compared with the prior art, the beneficial effects of this utility model are: When the rotating component and the rotating arm are in the same straight line, the rotating arm can be rotated backward to be perpendicular to the housing. At this time, holding the rotating component allows the fixing component at the bottom of the housing and the V-shaped slot to be installed on the cable, which facilitates the installation of the alarm mechanism and saves the trouble of finding additional tools for installation.

[0012] After the alarm mechanism is installed, the rotating arm can be rotated back and the right end of the rotating part can be rotated downwards to fit the cable into the notch. At this time, the cable can enter the interior of the mating opening of the rubber part, so that the rotating arm and the rotating part are perpendicularly connected to the cable, thereby supporting the alarm mechanism on the side wall of the housing and improving the stability of the alarm mechanism when installed on the cable.
