A protective drip irrigation equipment with pressure regulation function

Abstract

The present invention relates to a protective drip irrigation device with a pressure regulating function, which includes a pipeline and at least two drip irrigation heads, and also includes a detection mechanism and at least two protection mechanisms, the protection mechanism includes a protective cover and at least two installation components, the The detection mechanism includes a connecting shaft, a sliding rod, a second spring, an electric valve, a sliding sleeve, a second contact switch, two detection components and two first contact switches, and the installation component includes a fixed block, a connecting rod, a second contact switch A spring and a connecting sleeve, the detection assembly includes a rotating sleeve, a baffle and a transmission rod. In the protective drip irrigation equipment with pressure adjustment function, the water pressure inside the pipeline can be detected through the detection mechanism, and the internal pressure of the pipeline can be detected at the same time. The water pressure is adjusted to improve the drip irrigation effect of the drip irrigation equipment. The protection mechanism prevents the water flow from directly impacting the soil, reduces the chance of plant root damage, and improves the practicability of the drip irrigation equipment.

Description

technical field [0001] The invention relates to the field of water-saving irrigation equipment, in particular to a protective drip irrigation equipment with a pressure regulating function. Background technique [0002] Drip irrigation equipment uses plastic pipes to send water to the roots of crops through the orifice or dripper on the capillary with a diameter of about 10mm for local irrigation. It is currently the most effective water-saving irrigation method in arid and water-scarce areas. The water utilization rate can be reduced. Compared with sprinkler irrigation, drip irrigation has a higher water-saving and yield-increasing effect. At the same time, it can be combined with fertilization to more than double the fertilizer efficiency. It is suitable for irrigation of fruit trees, vegetables, commercial crops and greenhouses, and can also be used for irrigation of field crops in places where there is drought and water shortage. Its disadvantage is that the dripper is e...

Problems solved by technology

Its disadvantage is that the dripper is easy to scale and block, so the water source should be strictly filtered

[0003] As a kind of irrigation equipment, drip irrigation equipment greatly reduces the waste of water resources in the irrigation process. During the use of drip irrigation equipment in the prior art, if the internal water pressure of the pipeline is too large, it will cause water leakage from the drip irrigation head, and the setting will explode. Pipe, if the internal water pressure of the pipe is too small, it will cause the water output of the drip irrigation head to be small, prolong the drip irrigation time, and reduce the drip irrigation effect of the drip irrigation equipment. Not only that, when the internal water pressure of the drip irrigation equipment pipe is too high, the drip irrigation head It is easy to spray water with high water pressure. If the soil is soft, the water will wash away the soil and cause damage to the roots of the plants.
