Liftable water intake equipment with automatic water cutoff

Abstract

The invention discloses liftable type water taking equipment capable of automatically cutting off water, and belongs to the technical field of irrigation. The water taking equipment comprises a tapered tube, an inner tube, an outer tube, a fixed rod, a hollow sphere and a long tee joint. The inner tube is arranged on the inner part of the outer tube, and is in sealing contact with the upper end of the outer tube; the hollow sphere is in contact with the lower end of the inner tube; the fixed rod is fixed on the inner part of the outer tube; the rod body of the fixed rod penetrates through a through hole of the hollow sphere and a groove from bottom to top in sequence; the inner diameter of the through hole is greater than the outer diameter of the rod body; the lower end of the outer tube is connected with a water conveying pipeline; a side tube body of the long tee joint is connected with an irrigation system; when the inner tube is positioned underground, the tapered tube is arranged at the upper end of the inner tube and on the outer part of the outer tube; when the inner tube is positioned on the ground and the water taking equipment takes water, a lower tube body of the long tee joint extends into the inner part of the inner tube and is in contact with the hollow sphere; and the groove is separated from a first baffle block. The water taking equipment provided by the embodiment of the invention has a function of automatically cutting off water, is buried underground in a non-irrigation state, and is convenient to use.

Description

technical field [0001] The invention relates to the technical field of irrigation, in particular to a liftable water-taking device with self-cutoff water. Background technique [0002] In the current field of irrigation, in order to realize mechanized crop irrigation, water intake equipment is generally used to connect with the underground water pipeline and the irrigation system on the ground, such as pipe irrigation, sprinkler irrigation, drip irrigation and other water-saving irrigation systems. The water is sent to the irrigation system to irrigate the crops. Therefore it is very necessary to provide a simple and reliable water intake device. [0003] The water intake equipment used in the prior art is generally a water supply cock. However, the water supply cock is usually fixed at a specific position and a certain distance above the ground. For the normal cultivation of the field, it needs to be disassembled and stored and reinstalled during irrigation, which is incon...

Problems solved by technology

[0005] The special automatic retractable water fetcher for buried drip irrigation provided by the prior art needs to cut off the water source before connecting the tee with the telescopic pipe when connecting to the above-ground irrigation system, which is inconvenient to use and is not conducive to large-area water intake requirements.
