[0022] Embodiment 1

[0023] like Figure 1 As shown:

[0024] A fault detection device for a lightning protection grounding network of a flood drainage pump station comprises an electric box 1.

[0025] In this implementation scheme: the existing {publication (announcement) number}: CN220357164U discloses an online monitoring device for grounding grid resistance, and this patent discloses an operation panel. The grounding rod 7 in the present application document adopts the same technical means in this prior art. This technical means will not be described one by one here. For details about the improvement of this prior art, please refer to the disclosed technology below; to solve the technical problems existing in this prior art, as disclosed in the background technology above, "the scenes in which the device works are mostly building sites with complex environments, and the environment is difficult to achieve the purpose of fully automatic detection. Then, it is possible that the entire device will be offset during the detection work or it will be difficult to carry out the next step of detection. At this time, manual processing is required to deal with this situation, which affects the detection work." In terms of combined use, this problem is obviously a real problem that exists and is relatively difficult to solve. In view of this, in order to solve the above problems, a connecting line 2 and an electromagnet 3 are added on this basis.

[0026] More specifically:

[0027] like Figure 1-Figure 4 As shown:

[0028] In combination with the above content: it also includes a connecting wire 2, an electromagnet 3, an A clamp rod 4, an A clamp plate 5, a tension spring 6, a grounding rod 7, a B clamp plate 8, a B clamp rod 9 and a permanent magnet 10 arranged on one side of the electrical box 1, one side of the electrical box 1 is fixedly connected to one end of the connecting wire 2, and the other end of the connecting wire 2 is fixedly installed on one side of the electromagnet 3, and the electromagnet 3 is also fixedly installed on one end of the A clamp rod 4, the other end of the A clamp rod 4 is fixedly installed with an A clamp plate 5 that is fitted and connected to the grounding rod 7, and the other side of the grounding rod 7 is also fitted and connected to the B clamp plate 8 fixedly installed on one end of the B clamp rod 9, the adjacent surfaces of the B clamp plate 8 and the A clamp plate 5 are respectively fixedly connected to the two ends of the tension spring 6, and the end of the B clamp rod 9 away from the B clamp plate 8 is also fixedly connected to the permanent magnet 10.

[0029] In this embodiment: when it is necessary to perform fault detection on the grounding rod 7, the two groups of A clamps 5 and B clamps 8 provided on both sides of the electrical box 1 can be clamped on the two grounding rods 7, and the grounding network between the two grounding rods 7 can be checked. After the A clamp 5 and the B clamp 8 are connected, the tension spring 6 applies tension to the two, and enables the two to have a stable connection with the grounding rod 7. At this time, the electrical box 1 is in a power-off state, and then the electricity can be transmitted through the electrical box 1 through the connecting line 2 to the electromagnet 3 and the grounding rod 7 connected with the A clamp 5 and the B clamp 8. If the grounding rod 7 is in a normal working state, the grounding rod 7 can perform normal conductive work. And a complete power circuit can be realized. At this time, the electromagnet 3 will be energized and generate magnetic force, and the electromagnet 3 will push the permanent magnet 10 to move away from the electromagnet 3 through the generated magnetic force, and the A clamp rod 4 and the B clamp rod 9 will also rotate and stretch the tension spring 6 between the A clamp plate 5 and the B clamp plate 8, and the A clamp plate 5 and the B clamp plate 8 will also open and fall from the grounding rod 7, so that the staff will no longer have to remove the A clamp plate 5 and the B clamp plate 8 from the grounding rod 7, which can save operating steps. When the grounding rods 7 at two locations cannot form a power circuit, the A clamp plate 5 and the B clamp plate 8 will still be clamped on the grounding rod 7 and wait for the next detection work.

[0030] Going further:

[0031] In an optional embodiment, two connecting wires 2 and two electromagnets 3 are provided and extend outward from both sides of the electrical box 1 .

[0032] In this embodiment, the two connecting wires 2 extending from the outside of the electrical box 1 can form a complete loop through the connecting wires 2 and the normally functioning grounding rod 7 after being powered on, thereby achieving the purpose of powering on the two electromagnets 3 .

[0033] Going further:

[0034] In an optional embodiment, the A clamping rod 4 and the B clamping rod 9 are arranged crosswise.

[0035] In this embodiment, the cross-shaped A clamp rod 4 and B clamp rod 9 can drive the A clamp plate 5 and B clamp plate 8 at their ends to open when the electromagnet 3 and the permanent magnet 10 produce a repulsive effect, thereby achieving the purpose of separation from the grounding rod 7.

[0036] Going further:

[0037] In an optional embodiment, arc-shaped grooves matching the grounding rod 7 are formed on the surfaces of the A clamping plate 5 and the B clamping plate 8 .

[0038] In this embodiment, the grooves formed on the surfaces of the A clamping plate 5 and the B clamping plate 8 can provide a sufficient contact surface between the two and the grounding rod 7, thereby ensuring the stability of the device when it is clamped on the grounding rod 7.

[0039] Going further:

[0040] In an optional embodiment, the tension spring 6 is located on the central axis of the A clamping plate 5 and the B clamping plate 8 .

[0041] In this embodiment: the tension spring 6 arranged between the A clamp 5 and the B clamp 8 can apply sufficient pressure to the grounding rod 7 through the tension spring 6 when the two need to be connected to the grounding rod 7, thereby enabling the entire device to be effectively connected to the grounding rod 7.

[0042] Going further:

[0043] In an optional embodiment, the permanent magnet 10 and the electromagnet 3 are adjacent to and parallel to each other.

[0044] In this embodiment, the permanent magnet 10 disposed adjacent to the electromagnet 3 can generate a repulsive effect between the permanent magnet 10 and the electromagnet 3 after being energized, thereby enabling the A clamping plate 5 and the B clamping plate 8 to be quickly separated from the grounding rod 7 and fall off.

[0045] The working principle and use process of the utility model are as follows: when it is necessary to perform fault detection on the grounding rod 7, the two groups of A clamping plates 5 and B clamping plates 8 set on both sides of the electrical box 1 can be clamped on the two grounding rods 7, and the grounding network between the two grounding rods 7 can be checked. After the A clamping plate 5 and the B clamping plate 8 are connected, the tension spring 6 applies tension to the two, and enables the two to have a stable connection with the grounding rod 7. At this time, the electrical box 1 is in a power-off state, and then the electricity can be transmitted through the electrical box 1 through the connecting line 2 to the electromagnet 3 and the grounding rod 7 connected with the A clamping plate 5 and the B clamping plate 8. If the grounding rod 7 is in a normal working state, the grounding rod 7 can be normally The conductive work can realize a complete power circuit. At this time, the electromagnet 3 will be energized and generate magnetic force, and the electromagnet 3 will push the permanent magnet 10 to move away from the electromagnet 3 through the generated magnetic force, and the A clamp rod 4 and the B clamp rod 9 will also rotate and stretch the tension spring 6 between the A clamp plate 5 and the B clamp plate 8, and the A clamp plate 5 and the B clamp plate 8 will also open and fall from the grounding rod 7, so that the staff will no longer have to remove the A clamp plate 5 and the B clamp plate 8 from the grounding rod 7, which can save operating steps. When the grounding rods 7 at two locations cannot form a power circuit, the A clamp plate 5 and the B clamp plate 8 will still be clamped on the grounding rod 7 and wait for the next detection work.

[0046] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions described in the above embodiments or replace some of the technical features therein by equivalents.
