Automatic telescopic water spraying device

Abstract

The invention relates to an automatic telescopic water spraying device. A main body of the automatic telescopic water spraying device is buried under the ground surface, a cover plate of a protectionbox is flush with the ground surface, when sprinkling irrigation starts, a first-stage telescopic pipe and a second-stage telescopic pipe sequentially extend out of the ground, and a spray head at theupper end of the second-stage telescopic pipe extends out of the ground surface for sprinkling irrigation; and after sprinkling irrigation is completed, the second-stage telescopic pipe and the first-stage telescopic pipe sequentially retract to the underground from the ground surface, the cover plate of the protection box is closed, the whole device retracts to the position below the ground surface again. The device drives the two telescopic pipes to ascend and descend through the pressure of water, and an extra driving device is not needed, so that energy and equipment cost are saved; and in addition, the device has the structural characteristics of rising and retracting after irrigation, so that the defect that a plastic pipe at the lower end of a traditional spray head is prone to bend and incline is overcome, redundant supporting devices do not need to be arranged, high-quality sprinkling irrigation is guaranteed, and water resources are saved.

Description

technical field [0001] The invention relates to the technical field of sprinkler irrigation equipment, in particular to an automatic retractable water spray device. Background technique [0002] Sprinkler irrigation technology is to pressurize the water through related devices, and then transfer the water to the area that needs to be irrigated. The nozzle sprays the water into the atmosphere to form a lot of water points, forming the effect of rain, and the water can fall very evenly. On the surface, to achieve the effect of soil irrigation, the cost of using sprinkler irrigation technology is not very high, and sprinkler irrigation can accurately control the amount of water and the irrigation is relatively balanced, and the problem of leakage is not easy to occur during irrigation, which can effectively reduce the phenomenon of water and soil loss, so it is very It is favored and widely used in fields such as agricultural irrigation or garden irrigation. The nozzles of the...

Problems solved by technology

The nozzles of the existing sprinkler irrigation facilities usually use a plastic pipe fixed on the ground to support the nozzles for sprinkling irrigation. The plastic pipes are selected to avoid corrosion and block the nozzles, and the cost of the plastic pipes is low. The plastic pipes fixed on the ground are due to Man-made touch or its own deformation is very easy to produce bending and tilting (slanted sprinklers can often be seen on the lawn of the park or in the farmland), and the curved and tilted plastic pipe will reduce the spraying range of the sprinkler and cause uneven spraying, resulting in irrigation Unevenness and waste of water resources, so in farmland or gardens, it is often necessary to set a support slant on the plastic pipe of the sprinkler to avoid bending and tilting. This method increases the footprint of the sprinkler and is not beautiful, so it is necessary to design A new type of water spray device capable of automatic expansion and contraction
