10. A method for monitoring grounding resistance for lightning protection detection comprises the following steps:
s1: when the ground is flat, one person can hold any one support, the device can be pulled to move by the support, the device can be moved by universal wheels at the bottom, when the device is at a specific position to move or needs to be transported, in order to ensure the stability of the device, firstly, two persons respectively hold the two supports to lift the device, so that the four universal wheels are separated from the ground, then, one person screws a conflict bolt, so that the conflict bolt is separated from a conflict hole on a guide rod, at the moment, the hinge rod circularly moves along the hinge point of the hinge block under the contraction elasticity of a contraction spring until the hinge rod rotates to a parallel position, as shown in the figure, the conflict bolt is locked again, so that the conflict bolt can be contacted with the guide rod to complete locking, finally, the device is put down, so that the bottom of a shell positioned below is contacted with the ground, when the device is moved, the two mounting plates can buffer the vibration generated by the intelligent lightning grounding resistance, damage is reduced;
s2: when the intelligent lightning protection grounding resistance monitoring device body needs to be taken out, two picking blocks on the same side are operated by one person, the two picking blocks move upwards and downwards respectively to be away from the support, the picking blocks drive the connecting block to slide in the sliding hole, the connecting block drives the sliding block to slide in the cavity, the sliding block compresses the tensioning spring, the sliding block drives the fixing rod to slide out of the fixing groove in the embedded block, the fixing rod is retracted into the through hole in the bottom of the cavity, the support can be taken down at the moment, and two shells can be separated after the two supports are completely separated;
s3: during the separation shell, at first hold the shell that is located the top and upwards lift, make the shell break away from each other, the annular that is located the shell of top this moment slides along the thimble and moves upward, and the mounting groove that corresponds the mounting panel simultaneously breaks away from lightning protection ground resistance intelligent monitoring device body, and the shell that is located the top after demolising and finishes can take out lightning protection ground resistance intelligent monitoring device body, makes lightning protection ground resistance intelligent monitoring device body break away from the mounting groove that is located the mounting panel in the shell of below and can normally use.
