The invention discloses a spiral flow drainage device for a ground natural gas transportation pipeline and relates to the field of the petroleum and natural gas industry. The spiral flow drainage device comprises an accumulated liquid starting device, a spiral generating device, a liquid drop generating device and an accumulated liquid intercepting device. The accumulated liquid starting device isadopted, through the mode that a variable diameter pipe and the spiral flow generating device are combined, the flow speed is increased, impact force is increased, and spiral flow strength is improved, so that a gas flow impacts accumulated liquid at the low-lying position or the corner of the pipeline, the accumulated liquid is rolled up and carried through combination of a spiral flow and the impact force, and thus the accumulated liquid in the pipeline is effectively removed.

The invention provides an ad hoc network routing method and system suitable for a narrow-band condition. The method is based on the problems of overhigh overhead, serious channel conflict and the likeof an existing routing protocol under the half-duplex narrow-band condition studied by the invention. The demand of situation information of each node in the system is required in practical application of the wireless ad hoc network. Through reasonably designing a data packet frame structure, fusing the geographic position information of each node into a topology control message, the situation information of the whole network is effectively updated while neighbor detection is carried out. Data aggregation is carried out during each forwarding. Bandwidth resources are effectively saved. According to the method, the routing overhead is reduced, the problem of channel conflict under a half-duplex mode is solved, the situation awareness of each node of the system is completed in the routing establishment and maintenance process, and the wireless ad hoc network deployment and application under the narrow-band condition are realized.
