Description

Technical Field

[0001] This utility model relates to the field of power line protection technology, specifically to an alarm device for preventing external damage to overhead lines. Background Technology

[0002] Ensuring the normal operation of transmission and distribution lines in the power system is crucial. Accidents involving overhead lines can cause power outages, short circuits, and other power failures, resulting in significant losses for power producers and customers.

[0003] For example, utility model patent CN207133931U discloses an alarm device for preventing external damage to power transmission lines in building construction. This device includes an MGH-1000 tension sensor and a pull rope. The signal light and horn are bolted to the tops of the left and right support columns, respectively, and springs of a certain length are welded to the bottom of both columns. Two snap-fit ​​mounting brackets are bolted to the outer wall of the power transmission cable. An electrical box is also connected to the outer wall of the cable via a connecting plate and bolts. The bottom support columns of the signal alarm light and horn are elastic components, which are mounted on the cable. Therefore, when the cable is severely damaged, the support columns of the elastic components will sway elastically, causing the pull ropes on both sides of the MGH-1000 tension sensor to exert tension on it. Furthermore, an acrylic decorative cover is threaded onto the spring of the elastic component support column, resulting in an aesthetically pleasing structure and providing dual alarm functions: anti-theft and automatic wire cutting detection.

[0004] However, in actual use, it was found that the snap-on fixing bracket has poor fixing effect. When used on a single power transmission cable, the snap-on fixing bracket is prone to slippage, which makes it difficult to stabilize the alarm device and sensor.

[0005] Therefore, it is necessary to design an overhead line anti-external damage alarm device that is highly practical and has a positioning and locking mechanism. Utility Model Content
