Background technique

Sprinkler irrigation technology is an advanced irrigation method, which has the advantages of convenient management, high production efficiency, low operating cost, less project occupation and is conducive to automatic control. Currently, fixed sprinkler irrigation is used, and the sprinkler head is fixed on the water supply pipeline. The fixed sprinkler irrigation device has the following defects: first, because the sprinkler irrigation device is located on the ground surface, it affects farmland cultivation, wastes land resources, is easily damaged, and has a low service life; second, it is easy to lose. It is laborious and has poor anti-aging performance, but the buried telescopic sprinkler irrigation device avoids the above problems. The buried telescopic sprinkler irrigation is a new type of farmland irrigation equipment that can automatically expand and contract by hydrodynamic drive. The existing buried telescopic sprinkler irrigation pipe includes multi-section The expansion tube is driven by water pressure to extend, and after the sprinkling and irrigation is completed, the retraction of the expansion tube is realized by the self-gravity of the expansion tube and the return flow of the water drop.
