Pull-down self-locking warning sign of power line

Abstract

The invention provides a pull-down self-locking warning sign of a power line. The pull-down self-locking warning sign comprises a fixed bracket (1), a hanging bracket (2), a wire embedding device, a connecting rod (4) and an insulating rod (5), wherein the wire embedding device is arranged at the upper part of the fixed bracket (1); the hanging bracket (2) capable of moving up and down is arranged on the wire embedding device; a hook (8) used for hanging a wire is arranged on the hanging bracket (2); the lower part of the fixed bracket (1) is connected with a warning sign (7) by a screw; one end of the connecting rod (4) penetrates through the lower part of the fixed bracket (1); and the other end of the connecting rod (4) is connected with the insulating rod (5). The pull-down self-locking warning sign has the beneficial effects that the pull-down tself-locking warning sign is resistant to acid, alkali and corrosion and does not fade when being exposed to wind and rain in the field; the device has the advantages of being compact in structure, being light and small, being small in wind resistance, convenient and flexible in hanging, strong in adaptability, large in a contact area of a snap spring and the wire and high in stability coefficient of the snap spring, and therefore, the condition that clamping connection is firm and reliable in long-term operation is ensured.

Description

technical field [0001] The invention relates to a pull-down self-locking warning sign for power lines, which belongs to the field of early warning management of power line safety. Background technique [0002] The power line hanging signboard can remind the relevant personnel to pay attention, guide to the right direction, do not make mistakes or correct incorrect behaviors in time. In recent years, with the development of urban and rural areas, the rural distribution network has dense lines and complex operating environment, which has encroached on power line channels. The number of violations is also increasing. The electric power safety operation regulations stipulate that "production and operation units should set up obvious safety warning signs on production and operation sites and related facilities and equipment with relatively large risk factors, and electric power enterprises should standardize the installation of power line safety signs , to remind and warn operato...

AI Technical Summary

Problems solved by technology

[0003] In view of the above problems, the present invention provides a pull-down self-locking warning sign for power lines, which solves the safety problems caused by operators accidentally stepping on poles or entering electrified areas, and non-operators entering electrified areas by mistake, and improves the protection of power facilities. The safety warning function is used to warn the staff not to approach the live part of the equipment or to prohibit the operation of the equipment, the power signboard and to indicate where the staff can work and to remind other safety matters that must be paid attention to when working
