Locking device for drainage cable

Abstract

The invention discloses a locking device for a drainage cable. The locking device comprises a connecting rod, a locking block, a locking bolt, a fixed seat, a rotating seat, a rotating handle, a connecting rod, a pressing block, clamping teeth and the like. The lower part of the connecting rod is provided with a drainage cable clamping structure formed by the locking block, the lock bolt, the fixed seat, the rotating seat, the rotating handle and the like, the upper part of the connecting rod is provided with a movable block, a screw rod, a screw sleeve, a connecting U-shaped frame, a transverse clamping rod, a movable rod, a sliding rail, sliding teeth and the like which are used for externally clamping an external attachment position. The beneficial effects of the invention are that the connection reliability between the drainage cable and the main cable is prevented from being influenced by the dead weight of the drainage cable, the arc risk is reduced, and the safety of operators and power distribution equipment is effectively ensured.

Description

technical field [0001] The invention relates to the field of electric power engineering, in particular to a locking device for drainage cables. Background technique [0002] The operation method of the high-power cable drainage in the prior art is to peel off the outer covering insulation of the main cable, connect one end of the drainage cable to the main cable, and then cover the connection between the drainage cable and the main cable with an insulating layer such as Insulation tape, because the drainage cable has a strong self-weight, if the drainage cable is not lifted or pulled, it will directly affect the reliability of the connection between the drainage cable and the main cable, and it is very likely to cause the risk of arcing, which cannot effectively guarantee the operation The safety of personnel and power distribution equipment, so the existing prior art needs a locking device for drainage cables that can effectively ensure the safety of workers and power distr...
