[0033] Embodiment 1

[0034] Referring to Figures 1 - 5 , for the first embodiment of the present utility model, a grounding mechanism is provided. This device includes a hanging unit 100 and a grounding unit 200.

[0035] The hanging unit 100 includes a power connection frame 101, a mounting shell 105 provided on the power connection frame 101, a power connection component 103 provided on the power connection frame 101 and the mounting shell 105, and a blocking component 104 provided on the mounting shell 105; the grounding unit 200 is electrically connected to the power connection frame 101. Both the power connection frame 101 and the mounting shell 105 are in a U-shaped structure, and the blocking component 104 is located at the opening of the power connection frame 101. A monitor 301 is provided on the mounting shell 105, and is controlledly connected to the driving motor 104a and electrically connected to the power connection frame 101.

[0036] Among them, a plugging handle 102 is provided on the power connection frame 101; through the plugging handle 102, it can be inserted into the extension arm, so as to be conveniently hung on the cable at a high place.

[0037] Further, the grounding unit 200 includes a housing 203, a clamping component 201 slidably provided on the housing 203, and a moving component 202 provided on the housing 203 for pushing the clamping component 201 to move.

[0038] During use, first clamp the clamping component 201 on the grounding strip and fix it through the moving component 202, so that the moving component 202 clamps the grounding strip, thereby completing the grounding step. Connect the two ends of the conductive cable to the clamping component 201 and the power connection frame 101 respectively, so as to complete conduction. When the detection unit 300 detects that it has been connected to the grounding strip, it will judge that the grounding resistance is less than the preset value and is in a normal grounding state. The detection unit 300 controls the blocking component 104 to open, thereby exposing the opening of the power connection frame 101, and the power connection frame 101 can be hung on the power grid. The power connection component 103 clamps the cable for conduction, thereby ensuring reliable connection.

[0039] Embodiment 2

[0040] Refer to Figures 1 - 5 , which is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the blocking component 104 includes a driving motor 104a arranged on the mounting shell 105, a rotating frame 104c arranged on the output end of the driving motor 104a, and a blocking rod 104b arranged on the rotating frame 104c and abutting against the power connection frame 101.

[0041] Furthermore, the power connection component 103 includes two symmetrically arranged contact spring pieces 103a that are both rotatably arranged in the power connection frame 101, two elastic pieces 103b that are both arranged in the power connection frame 101 and used to push the contact spring pieces 103a to rotate, and two power connection pieces 103c that are both arranged in the mounting shell 105. The power connection component 103 is used to clamp the cable.

[0042] During use, when a part of the grounding unit 200 comes into contact with the ground wire, the monitor two 302 will send a signal to the monitor one 301, so that the monitor one 301 controls the driving motor 104a to start. The driving motor 104a drives the rotating frame 104c to rotate, and the rotating frame 104c drives the blocking rod 104b to rotate, thereby being able to release the blockage of the opening of the power connection frame 101, and the power connection frame 101 can be hung on the power grid. The cable contacts the contact spring piece 103a and the power connection piece 103c, and the elastic piece 103b can push the contact spring piece 103a to press on the cable, making the connection more reliable.

[0043] The remaining structures are the same as those in Embodiment 1.

[0044] Embodiment 3

[0045] Refer to Figures 1 - 5 , which is the third embodiment of the present invention. The difference between this embodiment and the second embodiment is that the clamping component 201 includes a clamping seat 201b arranged on the housing 203 and a clamping rod 201a slidably arranged on the housing 203; the monitor two 302 is electrically connected to the clamping seat 201b.

[0046] Further, a guiding groove 203a is provided on the housing 203. The clamping rod 201a is slidably arranged in the guiding groove 203a, and the moving component 202 is slidably arranged in the guiding groove 203a. The guiding groove 203a can guide the clamping rod 201a to prevent the clamping rod 201a from rotating.

[0047] Among them, the moving component 202 includes a connection nut 202b arranged on the clamping rod 201a, a mounting bracket 202c arranged on the housing 203, a threaded rod 202a rotatably arranged on the mounting bracket 202c and threadedly connected with the connection nut 202b and embedded in the clamping rod 201a, and a handle 202d arranged on the threaded rod 202a. The moving component 202 is used to drive the clamping component 201 to move, so that the clamping component 201 can clamp the grounding piece, and the multi-sided connection nut 202b is guided by the guiding groove 203a.

[0048] During use, rotate the handle 202d, so that the handle 202d drives the threaded rod 202a to rotate. The threaded rod 202a drives the connection nut 202b to move, and the connection nut 202b drives the clamping rod 201a to move. Since the clamping rod 201a is of an L-shaped structure, the clamping rod 201a can clamp the grounding piece on the clamping seat 201b to fix the grounding piece and make its connection more reliable.

[0049] The remaining structure is the same as that of Embodiment 2.

[0050] Embodiment 4

[0051] Referring to Figures 1 - 5 , this is the fourth embodiment of the present invention. This embodiment provides a power grid grounding monitoring device, which includes the above-mentioned grounding mechanism, and also includes a monitoring unit 300, which includes a monitor two 302 arranged on the grounding unit 200, and a monitor one 301 arranged on the hanging unit 100 and communicatively connected with the monitor two 302 and control-connected with the power connection component 103. The monitor one 301 is arranged on the installation shell 105, and is control-connected with the driving motor 104a and electrically connected with the power connection frame 101. The monitor two 302 is electrically connected with the clamping seat 201b.

[0052] During use, when the monitor 302 detects that it has been connected to the grounding plate, it will determine that the grounding resistance is less than the preset value and is in a normal grounding state. At this time, it is transmitted to the monitor 301 through the local area network or Bluetooth signal. The monitor 301 controls the blocking component 104 to open, so as to expose the opening of the power connection frame 101, and the power connection frame 101 can be hung on the power grid; indicator lights are provided on both the monitor 301 and the monitor 302. When the indicator lights are on, it indicates that it is in a normal working state; after hanging the device on the power grid, by setting a network communication module in the monitor 302, remote monitoring can be carried out, so that it is only allowed to be connected to the power grid after making reliable contact with the ground wire, ensuring safety.

[0053] The rest of the structure is the same as that of Embodiment 3.

[0054] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them.
