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 2):
The novel pressureless irrigation device according to  claim 1 , further comprising\n a floating ball water level control device having a water level adjustment control mechanism and a gauge, wherein a water inlet pipe ( 202 ) of the water supply water level control pool ( 201 ) horizontally penetrates through a side wall of the water supply water level control pool ( 201 ) from right to left and enters the water supply water level control pool ( 201 ); the water inlet pipe is connected with a port at right side of an equal-diameter tee ( 203 ), and the port is perpendicular to an upper port and a lower port of the equal-diameter tee ( 203 ); a lower end of an upper connecting pipe ( 204 ) is connected with the upper port of the equal-diameter tee ( 203 ); an upper end of the upper connecting pipe ( 204 ) is connected with the lower end of a female adapter ( 205 ); a square plug ( 206 ) is mounted at the upper end of the female adapter ( 205 ); the upper end of a lower connecting pipe ( 207 ) is connected with the lower port of the equal-diameter tee ( 203 ); the lower end of the lower connecting pipe ( 207 ) is connected with the upper port of a ball valve ( 208 ); the lower port of the ball valve ( 208 ) is connected with the upper end of a water distribution pipe ( 209 ); the water distribution pipe ( 209 ) has a suspended lower end and a downward pipe port; a horizontal head-on surface of a valve rod ( 210 ) of the ball valve ( 208 ) is inward, is perpendicular to a plane on which the upper connecting pipe ( 204 ), the lower connecting pipe ( 207 ) and the water inlet pipes ( 202 ) in the water supply water level control pool ( 201 ) are located; perpendicular to the plane, a right upper shaft ( 211 ) is fixed inwards and horizontal to the head-on surface at an upper portion of the upper connecting pipe ( 204 ); a right end of the upper connecting rod ( 212 ) is sleeved on a right upper shaft ( 211 ) after being drilled, and then the upper connecting rod ( 212 ) is equipped with a circular gasket and a gasket fixing plug pin; the upper connecting rod ( 212 ) is rotatable about the right upper shaft ( 211 ) in the plane perpendicular to the right upper shaft ( 211 ); a right end of the lower connecting rod ( 213 ) is fixed to the valve rod ( 210 ); when a left end and a right end of the lower connecting rod ( 213 ) are located on a same horizontal plane, the ball valve ( 208 ) is in a closed state; when the left end of the lower connecting rod ( 213 ) is separated from the horizontal plane and moves downwards, the valve rod ( 210 ) is drivable to rotate to open the closed ball valve ( 208 ); a left lower shaft ( 215 ) is fixed inwards to a head-on surface of the valve rod ( 210 ) parallel to the valve rod ( 210 ) at a lower end of a sleeve ( 214 ); the left end of the lower connecting rod ( 213 ) is sleeved on the left lower shaft ( 215 ) after being drilled and then is equipped with a circular gasket and a gasket fixing plug pin; a left upper shaft ( 216 ) is fixed inwards and horizontal to the head-on surface and parallel to the right upper shaft ( 211 ) on the sleeve ( 214 ) at a position with a distance equal to a distance between the valve rod ( 210 ) and the right upper shaft ( 211 ) above the left lower shaft ( 215 ); the left end of the upper connecting rod ( 212 ) is sleeved on the left upper shaft ( 216 ) after drilled and then is equipped with a circular gasket and a gasket fixing plug pin; a distance between the right upper shaft ( 211 ) and the left upper shaft ( 216 ) is equal to a distance between the valve rod ( 210 ) and the left lower shaft ( 215 ); a pull ring ( 218 ) is fixed at a upper end of a floating box connecting rod ( 217 ); a water-level control gauge ( 219 ) is arranged on a upper portion of the floating box connecting rod ( 217 ) and on the floating box connecting rod ( 217 ) below the pull ring ( 218 ); a lower end of the floating box connecting rod ( 217 ) penetrating through the sleeve ( 214 ) is fixed to a floating box ( 221 ) by a fixing nut ( 220 ) on the floating box ( 221 ); a control water level positioning pin ( 222 ) is mounted on an upward extended section of the sleeve ( 214 ) and on the sleeve ( 214 ) at a height higher than an upper cover plate of the water supply water level control pool ( 201 ) and convenient to operate above the left upper shaft ( 216 ); the upper connecting rod ( 212 ) and the lower connecting rod ( 213 ) move in the same plane perpendicular to the valve rod ( 210 ), the right upper shaft ( 211 ), the left lower shaft ( 215 ) and the left upper shaft ( 216 ); a pipe port at one end of the water outlet pipe ( 223 ) of the water supply water level control pool ( 201 ) penetrates through a side wall of the water supply water level control pool ( 201 ), and the pipe port is located at the bottom of the water supply water level control pool ( 201 ) with 20-25 cm higher than a bottom surface of the water supply water level control pool ( 201 ); and the other end of the water outlet pipe ( 223 ) of the water supply water level control pool ( 201 ) is connected with a water supply main pipe in the novel irrigator of the novel pressureless irrigation device.
