Abstract
The present invention is related to an intelligent and durable buried drainage pipe involving a method of separation and transmission. The intelligent and durable buried drainage pipe of the present invention includes an inner () and an outer () pipe. The outer pipe () is longer than the inner pipe (); a permanent magnet () is installed on a section of the outer pipe () that is longer than the inner pipe (). At least one electromagnet () is fixed at intervals from the permanent magnet (); the energized electromagnet () can attract the permanent magnet () causing it to slide. The end of the electromagnet () facing the permanent magnet () is provided with a distance sensor (), and the switch is turned on/off by the distance sensor (). An elastic telescopic member () is arranged between the permanent magnet () and the electromagnet ().
