Abstract

The present invention discloses a cable anti-external damage alarm, belongs to the field of alarms, and solves the problem of the lack of a cable anti-external damage alarm with a simple structure andan adjustable height which can be applied to different specifications of power cables, has a warning function, and can promptly warn and reminder the construction personnel when the power cable is squeezed and dug by the external force. The cable anti-external damage alarm mainly comprises a solar panel, a control box, a sleeve and a mounting cylinder. The bottom of the mounting cylinder is provided with a detector mounting plate and a side arm, the sleeve is provided with a sliding slot, and the mounting cylinder is provided with a limiting block; the detector mounting plate comprises an upper plate, a lower plate and a side plate, a pressure sensor I is arranged on the upper plate, a pressure sensor II is arranged on the lower plate, and a detector mounting side plate II is arranged onthe side plate; a sliding shaft is arranged at the bottom of the side arm, and a front end of the sliding shaft is provided with a detector mounting side plate I; and a pressure sensor III is respectively arranged on the detector mounting side plate I and the detector mounting side plate II. The cable anti-external force-damage alarm provided by the present invention is mainly used for the power cable to prevent external damage and performing an alarm prompt function.

Description

technical field [0001] The invention relates to an alarm, in particular to an alarm for preventing damage by external force of a cable. Background technique [0002] Directly buried cables are very commonly used in the actual laying process, and can better avoid obstacles such as ground buildings and trees. Compared with beam laying, the cost is also lower, and the occupation of ground space is reduced. However, there are also certain risks and blind spots after the direct burial of the cable distribution line. Since there are no markers above the power cable laying ground after construction, the markers are not clear, and the adjacent markers are far away, there is a risk that the ground construction will be damaged. . Among the annual power cable failures, most of them are caused by external force construction, resulting in a large amount of unnecessary and avoidable maintenance expenditures. [0003] At present, there is a lack of a simple structure, adjustable use heig...
