Among them, the clamping structure is horizontally arranged in the detection box 1, and the clamping structure includes a plurality of slots for fixing the grounding wire. The clamping structure is provided with a mounting slot 9 on one side of the rear side wall of the detection box 1, and an elastic component is installed in the mounting slot. A contact electrode is arranged on the side of the elastic component close to the grounding wire. The elastic component is used to make the contact electrode contact with the grounding wire so as to obtain the current change of the grounding wire. When the grounding wire is arranged in the slot, the elastic component is pressed. When the elastic component is in a pressed state, a force is provided to drive the contact electrode toward the grounding wire, so that the grounding wire and the contact electrode are fitted. A grounding current detector 7 is arranged on the inner wall of the detection box 1, and the contact electrode is electrically connected to the grounding current detector 7.

The direction of the telescopic spring 10 is perpendicular to the direction of the grounding wire. The direction of the limiting groove 11 is the same as the direction of the telescopic spring 10. A contact electrode 19 is installed at one end of the telescopic spring 10 close to the grounding wire, and a limiting block 20 adapted to the limiting groove 11 is installed on the outer surface of the contact electrode 19.

[0035] Specifically, three limiting blocks 20 are correspondingly distributed on the outer surface of each contact electrode 19 , and the limiting blocks 20 are slidably connected to the inner wall of the limiting groove 11 .

[0036] On the basis of the above-mentioned embodiments, in a preferred embodiment, the clamping structure includes a first fixing plate 12 and a second fixing plate 8, one side surface of the first fixing plate 12 is in contact with one side surface of the second fixing plate 8, and a plurality of equally spaced bending portions 13 are provided on the first fixing plate 12 and the second fixing plate 8, and the two bending portions 13 are arranged opposite to each other and fixedly connected to form a slot with a circular cross-section.

[0037] The left and right side walls of the detection box 1 are provided with card slots 3 , and both ends of the first fixing plate 12 and the second fixing plate 8 are card-engaged in the card slots 3 .

[0038] On the basis of the above-mentioned embodiments, in a preferred embodiment, the first fixing plate 12 and the second fixing plate 8 also include fixing portions staggered with the bending portions 13, the fixing portions on the first fixing plate 12 and the second fixing plate 8 are fixedly connected, and fixing holes 14 are provided on the fixing portions, and the inner wall of the fixing hole 14 is installed with a fastening bolt 15 threadedly connected to the fixing hole 14.

[0039] On the basis of the above-mentioned embodiments, in a preferred embodiment, the inner wall of the detection box 1 is provided with a control system, a ground resistance tester 6, a ground current detector 7 and a clamping structure from top to bottom, and the control system transmits the data of the ground resistance tester 6 and the ground current detector 7 to the terminal for monitoring. The control system includes a processor 17, a controller 16, a communication module 4 and a transmission antenna 5 which are electrically connected in sequence. The processor 17 is electrically connected to the ground resistance tester 6 and the ground current detector 7 respectively, and the communication module 4 is electrically connected to the transmission antenna 5; a protective door 2 is rotatably connected to the surface of the detection box 1.

[0040] On the basis of the above-mentioned implementation, in a preferred implementation, the vertical position of the ground current detector 7 corresponds to the vertical position of the slot hole one by one, and the number of the ground resistance testers 6 and the ground current detector 7 is the same as the number of the slot holes.

[0041] Among them, five groups of ground resistance testers 6, ground current detectors 7 and slots are provided.

[0042] The working principle of this embodiment is as follows: when it is in use, when it is necessary to install a lightning protection grounding fault warning and remote monitoring device, the detection box 1 is installed on the wall surface, and a cable inlet and outlet are provided on the detection box 1. When the installation is completed, the protective door 2 is rotated, and the grounding wire to be monitored is placed in the bending portion 13 opened on the surface of one side of the second fixing plate 8, and the grounding wire is electrically connected to the grounding resistance tester 6. When the placement is completed, the first fixing plate 12 is placed on the inner wall of the card slot 3, and the first fixing plate 12 and the second fixing plate 8 are in contact with each other. At this time, the fastening bolt 15 is inserted into the inner wall of the fixing hole 14, and the fastening bolt 15 is rotated to pass through the inner wall of the fixing hole 14 and inserted into the inner wall of the second fixing plate 8. The grounding wire is fixed between the second fixing plate 8 and the first fixing plate 12 through the bending portion 13 opened on the surface of one side of the second fixing plate 8 and the first fixing plate 12, thereby realizing the fixation of the grounding wire, and when the grounding wire is fixed, one side surface of the grounding wire will be in contact with the grounding wire. One side surface of the contact electrode 19 contacts each other and squeezes the contact electrode 19, and one side surface of the contact electrode 19 is fixedly connected to one end of the telescopic spring 10, so when the contact electrode 19 is squeezed, the telescopic spring 10 will be squeezed, so that the contact electrode 19 drives the limit block 20 installed on its outer surface to move along the inner wall of the installation groove 9, and at this time the limit block 20 will slide along the inner wall of the limit groove 11, so that one side surface of the contact electrode 19 can always contact one side surface of the grounding wire. When the grounding wire contacts other wires during use or generates current for other reasons, because one side surface of the contact electrode 19 contacts the grounding wire, and the contact electrode 19 is electrically connected to the grounding current detector 7, the grounding current detector 7 will transmit the detected data to the processor 17, and the processor 17 will analyze the magnitude of the current. At the same time, the controller 16 will control the communication module 4 to transmit the abnormal state of the grounding wire to the terminal, thereby facilitating the monitoring of the grounding wire.

[0043] When the lightning protection grounding fault warning and remote monitoring device is in operation, the grounding resistance tester 6 that monitors the grounding wire will continue to measure the resistance value of the grounding wire. It evaluates the goodness of the grounding wire by applying a certain current or voltage to the grounding system and then measuring the resistance value of the grounding system to the ground. The grounding resistance tester 6 will transmit the monitored data to the processor 17 electrically connected to it. The processor 17 will analyze the received data and transmit the real-time monitored data to the terminal through the communication module 4, which is convenient for real-time monitoring and early warning of the grounding device.

Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.
