Description

Technical Field

[0001] The utility model relates to the technical field of special tools for power plant grounding wires, in particular to a quick grounding wire tool. Background Art

[0002] During the maintenance of the generator set in the power plant, the PT cabinet equipment needs to be grounded. First, open the grounding wire window at the PT cabinet, use a common wiring clamp connected to the grounding copper wire to place it on the grounding copper column, and then rotate the grounding rod to push the pressing block so that the pressing block presses the grounding copper column tightly on the grounding clamp. Since the grounding copper column is located in a longitudinal hole and the window is too small, the operator needs to use one hand to go deep into the hole to fix the grounding wire clamp and use the other hand to rotate the grounding rod to push the pressing block to move. Since the grounding rod, the operator's arm and the window cover are crowded, the operating space is limited, the operation is extremely inconvenient, and the maintenance efficiency is affected.

[0015] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0016] like Figure 1 , Figure 2 As shown, an embodiment of the utility model proposes a quick grounding wire tool, including a grounding rod 1, a U-shaped bracket 2 and two elastic guides 5, the bracket 2 includes a base frame 3 made of conductive material and two connecting arms 4 fixedly connected to both ends of the base frame 3, the grounding rod 1 is fixedly connected to one connecting arm 4 of the bracket 2, the grounding copper wire 12 is fixedly connected to the base frame 3 to ground the bracket 2, the two elastic guides 5 are symmetrically arranged inside the bracket 2, the elastic guides 5 can be made of steel sheets with good elasticity and conductivity, and an arc-shaped clamp 6 for clamping the grounding copper column 11 is arranged in the middle of the elastic guide 5, one end of the elastic guide 5 is fixedly connected to the free end of the connecting arm 4, and the other end is close to the base frame 3.

[0017] When grounding is needed, the operator only needs to move the bracket 2 from the side of the grounding copper column 11 toward the grounding copper column 11, so that the grounding copper column 11 opens the two elastic guide plates 5, and the grounding copper column 11 is located at the arc-shaped clamping opening 6 of the elastic guide plates 5. The two elastic elastic guide plates 5 are pressed against the grounding copper column 11 under the action of their own elastic force, thereby forming grounding with the grounding copper wire 12, the conductive bracket 2 and the grounding copper column 11. This grounding operation makes it easy to grab the grounding copper column 11 in a small space, is easy to operate, and is convenient to use, thereby improving the efficiency of maintenance.

[0018] In this embodiment, if Figure 1 As shown, a plurality of first springs 7 are evenly and fixedly connected to the connecting arm 4, and the other end of the first spring 7 is fixed to the adjacent elastic guide piece 5. The plurality of first springs 7 apply pressure to the two elastic guide pieces 5 to improve the clamping effect of the elastic guide piece 5 on the grounding copper column 11, thereby ensuring grounding connectivity.

[0019] In this embodiment, if Figure 1 As shown, a second spring 8 is fixedly connected between the free ends of the elastic guide piece 5. When the elastic guide piece 5 cooperates with the grounding copper column 11, the second spring 8 is used to limit the grounding copper column 11 to prevent the grounding copper column 11 from being located at the end of the elastic guide piece 5. At the same time, the second spring 8 increases the clamping force of the elastic guide piece 5 on the grounding copper column 11.

[0020] In this embodiment, if Figure 1 As shown, the bottom frame 3 is fixedly connected with a triangular boss 9 on the side between the two connecting arms 4, and the end of the elastic guide piece 5 is located on the hypotenuse of the boss 9. In the process of squeezing the elastic guide piece 5 by the grounding copper column 11, the end of the elastic guide piece 5 abuts on the boss 9, and abuts against the end of the hypotenuse along the hypotenuse of the boss 9, so that the arc radius of the arc-shaped clamping opening 6 of the elastic guide piece 5 becomes smaller, the contact area with the grounding copper column 11 is increased, and the force of the first spring 7 at the end of the elastic guide piece 5 on the elastic guide piece 5 is further increased, so that the elastic guide piece 5 clamps the grounding copper column 11 more firmly.

[0021] In this embodiment, if Figure 1 As shown, the end of the elastic guide piece 5 is fixedly connected to the end surface of the connecting arm 4 by a bolt 10. It is convenient to replace the elastic guide piece 5 with weakened elasticity, thereby increasing the durability of the tool.

[0022] like Figure 1 , Figure 2 As shown, the grounding rod 1 can be extended by using a telescopic tube, or by using a threaded tube sleeve to adapt to grounding copper columns 11 of different depths.

[0023] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
