A power cable protection device, comprising a base, an arc groove is opened on one side of the base, a round pipe is arranged in the arc groove, a bearing is arranged inside the round pipe, and a cable hole is arranged on the bearing; A set of clamping components is provided at both ends of the inner side of the bearing; a fixing plate is provided at the end surface of the base away from the circular tube.

Preferably, the clamping assembly is composed of six sets of elastic assemblies; the elastic assemblies are distributed around the inner end of the bearing.

Preferably, the elastic component includes a first connecting plate and a second connecting plate, the first connecting plate is fixed on the inner surface of the bearing; a groove is opened on the end of the first connecting plate away from the bearing; the A spring is arranged on the outer side of the first connecting plate on the inner side of the bearing; the other end of the spring is connected to the movable splint; the second connecting plate is arranged on the movable splint inside the spring.

Preferably, the second connecting plate is slidably connected in the groove.

Preferably, a rubber plate is provided on a side of the movable splint away from the spring.

Preferably, two through holes are opened at both ends of the fixing plate; the fixing plate is fixed through the through holes by bolts.

The beneficial effects of the utility model are:

The utility model sets the fixing plate and opens a through hole on the fixing plate, so that the fixing plate can be fixed on the designated wall or other positions, and can support the power cable so that the cable does not fall off; by setting the base, it can be used as a power line When the cable needs to touch the ground, sometimes the surface of the round tube will be crushed by the car, the base will share part of the pressure, and the remaining pressure will be broken down by the round tube and the bearing, which greatly relieves the force on the power cable and protects it. The role of the cable; by setting the spring, the movable splint, the first connecting plate and the second connecting plate, the cables of different sizes can be protected; the direction and position of the cable will inevitably be moved during the construction process, and the role of the bearing will change The torsional shear force is resolved through rotation, thereby reducing the damage caused by the torsion of the power cable; and increasing the life of the power cable.
