Abstract:
The present disclosure belongs to the technical field of farm irrigation, and particularly relates to a novel pressureless irrigation device. The novel pressureless irrigation device of the present disclosure uniformly conveys irrigation water to crop plant root systems on the basis of a “connector” principle; and the size of a flow cross-section necessarily satisfies the extremely-low flowing speed requirement of “lossless conveyance” for the “connector” in a static pressure dominant operating state, thereby eliminating a problem of irrigator blockage which accompanies energy dissipation. Water enters the atmosphere via transpiration of crop plants, and a water supply water level control pool at a head portion is triggered to replenish the water. The water consumption and water replenishment are adaptive, and human intervention and additional energy are not required, thereby realizing low-cost and “fool-proof” automatic irrigation and true sense of uniform irrigation.

Claim (Index 1):
A novel pressureless irrigation device, comprising\n a novel irrigator for the novel pressureless irrigation device, wherein the novel irrigator comprises an equal-diameter downstream tee joint ( 1 ), a horizontal water inlet end ( 1 - 1 ) of the equal-diameter downstream tee joint, a horizontal water outlet end ( 1 - 2 ) of the equal-diameter downstream tee joint, a vertical water inlet end ( 1 - 3 ) of the equal-diameter downstream tee joint, a connecting pipe ( 2 ), a reducer pipe ( 3 ), a soil saturated water layer forming pipe ( 4 ), a porous water-permeable plate ( 5 ), a sandstone inverted filter layer ( 6 ) and backfill soil ( 7 ); the equal-diameter downstream tee joint ( 1 ) is connected to underground capillary pipes in series; the horizontal water inlet end ( 1 - 1 ) of the equal-diameter downstream tee joint is connected with a head end direction of one capillary pipe; the horizontal water outlet end ( 1 - 2 ) of the equal-diameter downstream tee joint is connected with a rear end direction of the capillary pipe; head ends of all capillary pipes are communicated with water supply water level control pool ( 201 ) by water supply branch pipes and water supply main pipes; rear ends of all the capillary pipes are connected with capillary pipe flushing valves by drainage branch pipes and drainage main pipes; the water supply branch pipes, the drainage branch pipes, the drainage main pipes and all the capillary pipes are located on a same horizontal plane; when noncapillary pipes perform flushing operation, the flushing valves are in a closed state; the vertical water inlet end ( 1 - 3 ) of the equal-diameter downstream tee joint is connected with a small head of the reducer pipe ( 3 ) by the connecting pipe ( 2 ); a lower end of the soil saturated water layer forming pipe ( 4 ) is vertically inserted into a large head of the reducer pipe ( 3 ); the porous water-permeable plate ( 5 ) is placed at the bottom of the soil saturated water layer forming pipe ( 4 ) and on one side of the large head of a diameter reducing position of the reducer pipe ( 3 ); the sandstone inverted filter layer ( 6 ) is placed on the porous water-permeable plates ( 5 ); the backfill soil ( 7 ) is placed on the sandstone inverted filter layer ( 6 ); a distance between a top end of the soil saturated water layer forming pipe ( 4 ) and a soil surface of an irrigated farmland is 40-45 cm; a height adjustment range of a soil saturated water layer is from the bottom of the backfill soil ( 7 ) in the soil saturated water layer forming pipe ( 4 ) to a top of the soil saturated water layer forming pipe ( 4 ); and a height of the soil saturated water layer is adjusted by adjusting a water level of a corresponding water level control pool for water supply ( 201 ).
