See Fig. 3, the ground rod that the power supply line of the present embodiment is used, it when in use, the staff holds the insulating rod 11 of operating bar 1 and lifts, and makes articulated part 2 by the top of articulated plate 21 The arc-shaped part 21-1 of the arc part 21-1 is hooked on the power cable 6 to be grounded, and then the insulating rod 11 of the operating rod 1 is rotated to drive the insulating rod 11 of the opera...

Abstract

The invention provides a ground rod for a power supply line. The ground rod comprises an operation rod, a hooking piece, a meshing plate and a grounded annealed copper wire, wherein the operation rod comprises an insulating rod body and a screw, and a connecting terminal is arranged at one end of the grounded annealed copper wire. The ground rod is structurally characterized by further comprising a protective spring, the hooking piece comprises a hooking plate and an operating rod connecting plate, the hooking plate and the operating rod connecting plate are integrally connected, the screw of the operating rod penetrates through the operating rod connecting plate from bottom to top and extends upwards, an arc-shaped meshing port concave downwards is formed in the upper end of the meshing plate, the lower end face of the meshing plate is fixedly connected with the upper end of the screw of the operating rod, the grounded annealed copper wire is in bolted connection with the hooking plate of the hooking piece through the connecting terminal of the grounded annealed copper wire, the protective spring is connected to the side, provided with the connecting terminal, of the grounded annealed copper wire in a sleeving mode, and one end of the protective spring is fixedly connected with the connecting terminal of the grounded annealed copper wire. By the adoption of the ground rod, the strand breaking rate of the grounded annealed copper wire can be effectively reduced, the effect that short-circuit current is grounded through the ground rod is guaranteed, and the service life of the ground rod is prolonged.

[0024] (Example 1)

[0025] see figure 2 The grounding rod used for the power supply line of this embodiment is mainly composed of the operating rod 1, the hook 2, the biting plate 3, the grounding soft copper wire 4 and the protection spring 5.

[0026] The operating rod 1 is composed of an insulating rod 11 at the lower part and a screw 12 at the upper part fixedly connected.

[0027] The hook 2 is composed of a hook plate 21 and an operating lever connecting plate 22 integrally connected. The hook plate 21 is arranged vertically; the material of the hook member 2 is a conductor. The hook plate 21 of the hook member 2 is formed by integrally connecting an arc portion 21-1 provided on the upper part and a straight plate portion 21-2 provided on the lower part. The lower end of the straight plate portion 21-2 of the hook plate 21 is provided with bolt holes penetrating forward and backward; the operating rod connecting plate 22 is a horizontally arranged plate body; the middle of the operating rod connecting plate 22 is provided with a bolt hole penetrating vertically; The hook plate 21 is integrally connected with the right end surface of the operating lever connecting plate 22 by the lower left end surface of the straight plate portion 21-2.

[0028] The screw 12 on the upper part of the operating rod 1 is matched with the bolt hole of the operating rod connecting plate 22 of the hook 2 and extends upward through the operating rod connecting plate 22 from bottom to top.

[0029] The occlusal plate 3 is a horizontally arranged plate body. The upper end of the occlusal plate 3 is provided with a downwardly recessed arc-shaped occlusal opening 31. The arc-shaped occlusal opening 31 is in use with the arc part of the hook plate 21 of the hook 2 21-1 cooperate. The bite plate 3 is fixedly connected with the upper end surface of the screw 12 of the operating rod 1 by its lower end surface.

[0030] One end of the grounding soft copper wire 4 has a connecting terminal, and the grounding soft copper wire 4 is matched with the bolt hole of the straight plate part 21-2 of the hook plate 21 through its connecting terminal, and is fixed with the hook plate 21 of the hook 2 by bolts connection. The other end of the grounding soft copper wire 4 is grounded when in use.

[0031] The protective spring 5 is sleeved on the side of the grounded soft copper wire 4 with the connecting terminal; one end of the protective spring 5 is fixedly connected with the connecting terminal of the grounded soft copper wire 4. The length of the protection spring 5 is determined according to actual needs.

[0032] see image 3 For the grounding rod for the power supply line of this embodiment, when in use, the worker holds the insulating rod 11 of the operating rod 1 and lifts it up, so that the hook 2 is hooked on the upper arc 21- of the plate 21. 1 Hook on the power cable 6 that needs to be grounded, and then rotate the insulating rod 11 of the operating rod 1 to drive the insulating rod 11 of the operating rod 1 to rotate upward, thereby driving the bite plate 3 to rise, and the bite plate 3 has its arc-shaped bite opening 31 Cooperating with the arc portion 21-1 of the hook plate 21 of the hook 2, it can firmly bite the power cable 6 that needs to be grounded, thereby ensuring that the ground rod of this embodiment is in good contact with the power cable 6 that needs to be grounded. Grounding effect.

[0033] During use, due to the protective spring 5, when the grounding soft copper wire 4 swings due to influence factors such as wind, the protective spring 5 can control the bending arc of the connection between the grounding soft copper wire 4 and the hook 2 to eliminate grounding The lateral shear force of the connecting terminal of the flexible copper wire 4 to the flexible copper wire can effectively reduce the strand breakage rate of the grounded flexible copper wire 4, increase the service life of the ground rod, and ensure the grounding effect and power supply safety.
