Description

Shock-resistant water supply and drainage pipeline joint structure Technical Field The utility model discloses an anti-seismic water supply and drainage pipeline joint structure, and relates to the technical field of pipeline joints. Background Underground pipeline systems are the core infrastructure for information transmission in modern society, and the reliability of the underground pipeline systems in earthquake disasters is directly related to life lines of post-earthquake emergency command and rescue communication. The damage to the underground pipeline caused by the earthquake mainly results from the severe movement of stratum, including soil displacement, shearing deformation, sand liquefaction and the like, and the acting forces are extremely easy to cause structural damage to the pipeline system. At present, a telescopic corrugated pipe is generally adopted as a joint in the aspect of earthquake resistance in the traditional underground pipeline system, the corrugated pipe has certain restorability, but the corrugated pipe is excessively stretched due to overlarge vibration receiving amplitude, the restorability is reduced, the corrugated pipe cannot rebound completely, if the pipeline system forms negative pressure due to the water hammer phenomenon, the phenomenon of internal suction collapse can occur in a thin-wall part reinforced by a steel ring in the stretched corrugated pipe, and water flow is blocked and even the structure of the telescopic pipe part is damaged. Disclosure of utility model The utility model aims to design an anti-seismic water supply and drainage pipeline joint structure capable of resetting an extension pipe after earthquake. The telescopic pipe comprises a left pipe body, a right pipe body and a telescopic pipe arranged between the two pipe bodies, wherein the telescopic pipe comprises a telescopic part and a connecting part, the connecting part extends into inner cavities of the two pipe bodies and is fixedly connected with the two pipe bodies, a left mounting ring and a right mounting ring are respectively arranged at adjacent ports of the left pipe body and the right pipe body, a group of lantern rings are arranged on opposite surfaces of the left mounting ring and the right mounting ring along the circumferential direction of the left mounting ring, and a tension spring is hung between the lantern rings on the left mounting ring and the lantern rings on the right mounting ring, which are opposite in position. Further, a left shield screwed with the left tube body is arranged on the periphery of the port of the left tube body, a right shield screwed with the right tube body is arranged on the periphery of the port of the right tube body, and the diameter of the right shield is smaller than the aperture of the left shield. Further, the left shield extends to one side of the right shield and wraps the right shield. Further, a rubber ring is arranged between the left shield and the right shield, and the rubber ring is embedded on the outer peripheral surface of the right shield. Further, limiting protrusions which are fixedly connected or integrally formed with the left tube body and the right tube body are arranged in the inner cavities of the left tube body and the right tube body, and sealing rings are arranged between the limiting protrusions and the connecting portions of the telescopic tubes. The utility model is characterized in that a left mounting ring and a right mounting ring are respectively arranged at the joint of two pipe bodies, a group of tension springs are hung between the two mounting rings, when the pipe bodies are shocked, the tension springs can be stretched to play a role in flexible shock absorption, meanwhile, the tension springs can be unfolded along with the shock, certain limitation is brought to the stretching of the tension springs through self resilience force, the phenomenon of overstretching is avoided, after the shock is ended, the tension springs can pull and reset the tension springs, so that the tension springs keep a contracted state, the influence of negative pressure is avoided, and the phenomena of internal suction collapse and the like are avoided. When the utility model is applied to an underground closed structure, the two shields can isolate connecting pieces such as a tension spring, a telescopic pipe and the like from the outside, the service life of the connecting pieces is prolonged, a rubber ring is arranged between the left shield and the right shield, and when the two shields are vibrated, a certain displacement space can be reserved between the two shields through the rubber ring, so that the two shields can swing along with vibration, the damping effect of the tension spring is prevented from being influenced, and the sealing of the tension spring is ensured.
