Description

Technical Field

[0001] The utility model relates to the technical field of special tools for oil supply valves, in particular to a portable tool for quickly installing a ground wire. Background Art

[0002] The power plant contains 4 generator sets. In the primary main connection of each unit, there are 4 voltage transformers (PT) in the generator part.

[0003] During maintenance, the 2PT three-phase short circuit and grounding are required. When grounding, the window is opened at the PT cabinet, and the grounding rod is rotated to push the pressing block to press the grounding copper plate tightly on the grounding clamp. Since the window is too small, the operator needs to go deep into the window with one hand to fix the grounding clamp and rotate the grounding rod with the other hand, which greatly restricts the operation. In addition, the PT cabinet is very close to the excitation transformer next to it, and the grounding rod, the operator's arm, and the window cover are crowded, which brings great inconvenience to the installation of the grounding wire in a small space.

[0016] In the above drawings: grounding rod 1, grounding clamp 2, elastic guide plate 3, first spring 4, connecting plate 5, pressing block 6, screw 7, cavity 8, slide groove 9, bolt 10, connecting rod 11, extension rod 12, rubber sleeve 13, second spring 14, concave groove 15, grounding copper wire 16. DETAILED DESCRIPTION

[0017] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0018] like Figure 1 As shown, the embodiment of the utility model proposes a portable quick installation ground wire tool, including a grounding rod 1, a U-shaped grounding clamp 2, an elastic guide 3, and a plurality of first springs 4. The grounding rod 1 is fixedly connected to the grounding clamp 2. The grounding clamp 2 is made of a conductor and connected to the grounding copper wire 16. The opening direction of the grounding clamp 2 is perpendicular to the grounding rod 1. The elastic guide 3 is set in an L shape. One end of the elastic guide 3 is fixed on the grounding clamp 2, and the other end is set in the grounding clamp 2. The elastic guide 3 and the inner wall of the grounding clamp 2 form an elastic clamp for clamping the three-phase grounding copper plate. The first springs 4 are fixed in parallel in the grounding clamp 2 and fixedly connected to the elastic guide 3 to support the elastic guide 3. The elastic guide 3 can be made of a steel sheet with good elasticity.

[0019] When grounding is required, the window of the PT cabinet is opened, and the operator only needs to move the grounding clamp 2 from the side of the grounding copper plate toward the grounding copper plate, so that the first spring 4 pushes the elastic guide 3 to press the grounding copper plate onto the grounding clamp 2, which is convenient for grabbing the grounding copper plate in a small space, and is easy to operate and use.

[0020] In this embodiment, if Figure 1 As shown, the grounding clamp 2 includes an L-shaped connecting plate 5, a pressing block 6 and a screw 7. The connecting plate 5 is provided with a cavity 8 and a slide groove 9 for the pressing plate to slide. The screw 7 is rotatably mounted on the connecting plate 5 and arranged in the cavity 8. The screw 7 is threadedly connected to the portion of the pressing plate located in the cavity 8. The screw 7 is used to push the pressing plate to slide on the connecting plate 5. The screw 7 is rotated to push the pressing block 6 to move on the connecting plate 5, and the pressing block 6 is fixed to an appropriate position on the connecting plate 5 through threaded engagement, so as to adjust the distance between the pressing block 6 and the elastic guide piece 3, so as to avoid the elastic force of the elastic guide piece 3 being reduced and affecting the clamping of the grounding copper plate.

[0021] In this embodiment, if Figure 1 As shown, one end of the elastic guide piece 3 is fixed to the opening of the grounding clamp 2 by a bolt 10. This facilitates the replacement of the elastic guide piece 3 with elastic loss.

[0022] In this embodiment, if Figure 1 As shown, the grounding rod 1 includes a connecting rod 11 and a ceramic extension rod 12, wherein the connecting rod 11 is fixedly connected to the grounding clamp 2, and the ceramic extension rod 12 is threadedly connected to the connecting rod 11. The ceramic extension rod 12 prevents electric shock and increases the length of the grounding rod 1.

[0023] In this embodiment, if Figure 1 As shown, a rubber sleeve 13 is fixedly connected to the extension rod 12. The rubber sleeve 13 increases the friction of the operator holding the grounding rod 1 and also performs insulation to avoid electric shock.

[0024] In this embodiment, if Figure 1 As shown, a second spring 14 is fixedly connected between the free end of the elastic guide piece 3 and the inner wall of the grounding clamp 2. The clamping force of the elastic guide piece 3 is increased, and the grounding copper plate is also limited.

[0025] In this embodiment, if Figure 1 As shown, a plurality of concave grooves 15 are provided on the inner wall of the grounding clamp 2 adjacent to the elastic guide plate 3, thereby increasing the friction force of the grounding clamp 2 on the grounding copper plate.

[0026] 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.
