Abstract
The invention discloses an anti-drop structure and an anti-drop method for a wireless inclinometer. The anti-drop structure comprises a counter bore formed in a guide slope, a through hole which penetrates through a non-magnetic pup joint, and a pulser jackscrew mounted on a circulating loop. The anti-drop method comprises the following steps of: mounting the circulating loop into the non-magnetic pup joint, fixing the non-magnetic pup joint by using a screw, dropping the wireless inclinometer into the circulating loop, mounting the pulser jackscrew from the through hole into the non-magnetic pup joint, and mounting the pulser jackscrew to the circulating loop in a threaded connection mode and pressing against the pulser so as to enable the pulser jackscrew to press against the counter bore in the guide slope; and coating a thread adhesive on the jackscrew cap provided with an O-shaped sealing ring and mounting the jackscrew to the non-magnetic pup joint. The off-key problem of the inclinometer is well solved, the underground application reliability of the inclinometer is improved, and the frequency of unnecessary trip-out caused by off-key of the inclinometer is greatly reduced; meanwhile, the anti-drop structure is simple to operate and simple and convenient in structure, and the on-site construction efficiency is greatly improved.
