[0022] like Figures 1-3 As shown, a grounding nail grounding reliability detection triggering mechanism includes a guide sleeve 2 connected to the nail body 1 via a connecting unit. The guide sleeve 2 has a through hole 3 through which the nail body 1 can pass. A sliding sleeve 4 is retractably installed within the through hole 3 of the guide sleeve 2, and the sliding sleeve 4 is movably sleeved outside the nail body 1. Two conductive trigger rods 5 are provided on one side of the guide sleeve 2, and the trigger rods 5 are insulated from the guide sleeve 2. A conductive detection disk 6 is provided on one side of the sliding sleeve 4, with the lower ends of the trigger rods 5 positioned above the detection disk 6. The trigger rods 5 are electrically connected to a detection module. The detection disk 6 can be moved from a non-triggering position to a triggering position under external force. When the detection disk 6 is in the triggering position, the lower ends of both trigger rods 5 abut against the detection disk 6, triggering the detection module to detect and obtain the grounding nail's penetration depth information.
[0023] The detection module can be connected to the nail body 1 or installed on other objects. The new triggering mechanism is installed at a designated position on the nail body. During the process of the nail being driven into the soil, the soil will exert a pushing force on the detection disc 6, causing the detection disc 6 to rise until the lower ends of the two trigger rods 5 abut against the detection disc 6. The two trigger rods are connected through the detection disc. At this time, the detection device determines that the penetration depth is qualified based on the change of the electrical signal.
[0024] Using this new detection triggering mechanism, no additional professional measuring tools are required for measurement. It is simple to operate, low in cost, and the measurement results are not affected by the operator's experience, ensuring accuracy.
