Description

[0002] In grounding construction, the key factors affecting the construction quality include the burial depth of the grounding wire and grounding electrode, the quality of the grounding material, and the overlapping length of the grounding wire. Among them, the overlapping quality is crucial. During the on-site construction acceptance, the detection of the grounding burial depth, overlapping length and galvanized layer thickness is mainly carried out by the inspectors one by one. Due to the limitations of the construction site and other reasons, the measurement is often not easy to carry out. For example, the width of the grounding trench is too small, and it is difficult to detect the overlapping quality after the grounding wire is laid in the grounding trench. The detection efficiency is low and the measurement accuracy is poor. Summary of the invention

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0024] like Figure 1 As shown, a grounding wire joint detection device includes a support frame 1, a first lifting plate 2 arranged in the support frame 1 and lifted and lowered in the support frame 1, a detection mechanism arranged below the first lifting plate 2 and a grabbing mechanism arranged at the lower end of the first lifting plate 2; when working, the support frame 1 straddles the grounding trench position, the first lifting plate 2 descends, the grabbing mechanism grabs the grounding wire, and grabs the grounding wire to the detection mechanism position, and the detection mechanism detects the quality of the grounding wire joint position, thereby reducing the detection difficulty and improving the detection efficiency.

[0025] like Figure 2 and Figure 3 As shown, the grabbing mechanism includes a vertical rod 3 arranged at the bottom of the first lifting plate 2, and a rotating plate 4 arranged at the bottom of the vertical rod 3, and a groove 5 is provided at the front end of the rotating plate 4; when the first lifting plate 2 descends to the bottom, the rotating plate 4 rotates, and the groove 5 hooks the grounding wire to hook up the grounding wire, and the grounding wire is lifted to the detection mechanism for detection, and there is no need for people to enter the grounding trench to lift the grounding wire, which is easy to operate.

[0026] like Figure 2 and Figure 3 As shown, the detection mechanism includes a second lifting plate 6 arranged on the vertical rod 3 and lifted on the vertical rod 3, a vertical plate 7 arranged at the lower end of the second lifting plate 6, and an arc plate 8 arranged at the lower end of the vertical plate 7 and rotating at the lower end of the vertical plate 7.

The two metal sheets 9 correspond to the two grounding wires at the joint position respectively. The metal sheets 9 are connected into a loop through a wire. A light bulb is provided on the wire loop. When the two metal sheets are in contact with the corresponding grounding wires, the wires are connected and the light bulb lights up, thereby ensuring that the grounding wire connection is reliable.

[0027] like Figure 3As shown, the front end of the rotating plate 4 is connected to the front end of the second lifting plate 6 through a connecting rod 11. When the first lifting plate 2 descends, in the initial state, the second lifting plate 6 descends synchronously. After the arc plate 8 at the lower end of the vertical plate 7 is supported on the ground, the second lifting plate 6 does not move, and the first lifting plate 2 continues to descend. Under the action of the connecting rod 11, the front end of the rotating plate 4 swings upward, and the grounding wire is located in the groove 5, thereby lifting the grounding wire. When the grounding wire is lifted, the arc plate 8 first overcomes the elastic force of the tension spring and swings upward. When the grounding wire is separated from the arc plate 8, under the action of the tension spring, the arc plate 8 is horizontal, and the arc plate will not interfere with the lifting and lowering of the grounding wire.

[0028] like Figure 1 As shown, the bottom of the support frame 1 is provided with walking wheels 12.

[0032] like Figure 3 As shown, a baffle 16 is provided on the vertical rod 3 to limit the lower end position of the second lifting plate 6 to prevent the second lifting plate 6 from falling from the vertical rod.
