Automatic desilting control device and method for drop-irrigation head of multi-sand driven well

Abstract

The invention discloses automatic desilting control device and method for a drop-irrigation head of a multi-sand driven well. The device comprises a multi-sand driven well drop-irrigation head automatic desilting control cabinet (17), a desilting electric valve (11) and a water inlet electric valve (12), wherein the desilting electric valve (11) is positioned on a desilting pipeline and is connected with the multi-sand driven well drop-irrigation head automatic desilting control cabinet (17) through a control cable of the desilting electric valve (11); and the water inlet electric valve (12) is positioned on a drop-irrigation head water inlet pipeline and is connected with the multi-sand driven well drop-irrigation head automatic desilting control cabinet (17) through a control cable of the water inlet electric valve (12). The multi-sand driven well drop-irrigation head automatic desilting control device provided in the invention has the characteristics of simple structure and convenient use and automatically accomplishes sand discharging in the process of drop irrigation so as to reduce the damage of slit to drop-irrigation equipment in the early stage of running of the driven well without manpower for desilting, thereby improving the efficiency of drop irrigation and saving the cost of drop irrigation.

Description

technical field [0001] The invention relates to the technical field of farmland machine well irrigation, in particular to an automatic sand discharge control device and method for a drip irrigation head of a sandy machine well. Background technique [0002] In the existing drip irrigation control system for the farmland motor-driven well micro-irrigation area, because the motor-driven well carries a large amount of sediment with the water in the early stage of operation, the control valve and dripper of the drip irrigation control system are often blocked, so that the drip irrigation control system cannot work normally and cannot realize the Efficient irrigation of farmland. Especially in the early stage of pumping irrigation in newly drilled wells or high-sediment well irrigation areas, for example, within ten to twenty minutes, the pipes contain a large amount of sediment, and the originally clear influent water becomes very turbid, and a large amount of sediment Often th...

[0002] In the existing drip irrigation control system for the farmland motor-driven well micro-irrigation area, because the motor-driven well carries a large amount of sediment with the water in the early stage of operation, the control valve and dripper of the drip irrigation control system are often blocked, so that the drip irrigation control system cannot work normally and cannot realize the Efficient irrigation of farmland

Especially in the early stage of pumping irrigation in newly drilled wells or high-sediment well irrigation areas, for example, within ten to twenty minutes, the pipes contain a large amount of sediment, and the originally clear influent water becomes very turbid, and a large amount of sediment Often the various filtering facilities at the head of drip irrigation cannot operate normally, causing a large amount of sediment to accumulate at the valve or the hole of the dripper through pipelines at all levels, causing a large number of irrigation equipment to fail early

Due to the use of sedimentation tanks for sand discharge, the project cost is relatively high, and the settled sediment needs to be removed manually, which is labor-intensive. Due to the need for dredging during the peak water consumption period, drip irrigation cannot be performed, and it is difficult to take advantage of drip irrigation technology.
