Sliding anti-reverse power supply device

Abstract

The invention discloses a sliding anti-reverse power supply device comprising an outer cover having a cylindrical space for matching the shape of a wire and wrapping the wire. The outer cover comprises first and second fixing sections fixed to the two sides of a wire exposed portion, and a sliding section sleeving the first fixing section and the second fixing section. The sliding section can slide along the first fixing section or the second fixing section to expose or close the wire exposed portion. When the sliding anti-inversion power supply device is installed on the grounding portion ofthe wire, the sliding section can be pulled on the ground by an operating rod, so that the wire exposed portion can be completely exposed, thereby increasing the contact area and enhancing a groundingdrainage capability. When the power supply is normal, the sliding section is pulled by the operating rod, the wire exposed portion is closed to achieve a waterproof sealing effect, which is simple inoperation. A climbing operation is not required when the grounding or the repairing is completed, and the sliding section can be directly pulled on the ground through the operating rod. No aerial operation is required so as to reduce danger and save time.

Description

technical field [0001] The invention relates to the technical field of electric equipment, in particular to a sliding type anti-falling power supply device. Background technique [0002] When working on electrical equipment, grounding wires must be connected to all sides that may receive electricity to prevent sudden incoming calls or improper use of self-provided generators by certain users in the line to cause reverse power supply and injure workers. However, the existing anti-falling power supply device needs to operate the rod to open the shield shell up and down when the grounding wire is used, and also needs to operate the rod to close the shell after maintenance, which is inconvenient to operate and not high in safety. At the same time, the existing anti-falling power supply device has poor waterproof performance, and it is easy to cause water to enter the grounding part, which increases safety hazards. Therefore, need badly a kind of simple and easy to operate, safe...
