1-h
2) and section flow Q between relation obtain flow Q by aqueduct, and send the automatic adjustment that dish valve opening is carried out in gate regulating command, to reach the object of flow automatic regulation to motor.The present invention has the advantages such as certainty of measurement is high, easy construction, simple operation.And the automatic management of whole irrigated area remote control and regulation can be realized by gprs system with Long-distance Control center line due to its automatic regulating system, there is higher promotional value and application prospect.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further illustrated:
Fig. 1 is system of the present invention composition structural representation.
Fig. 2 is that A-A of the present invention is to sectional view.
Fig. 3 is that B-B of the present invention is to sectional view.
In figure: 1 is that agricultural-door controls dish valve, 2 and being motor for automatically gathering controller, 3,4 being solar panels, 5 being pressure sensor, 6 being aqueduct, 7 being channel, 8 being Upstream Canal, 9 being Channel of Downstream, 10 being yi word pattern barricade, 11 being valve body, 12 being dish plate, 13 being control lever.
Detailed description of the invention
Catchment position, flow observing and controlling divide water agricultural-door in the self-action of one, comprising: agricultural-door controls dish valve 1, automatically gathers controller 2, motor 3, solar panels 4, pressure sensor 5, aqueduct 6, channel 7, Upstream Canal 8, Channel of Downstream 9, yi word pattern barricade 10 etc.Described agricultural-door controls dish valve 1 and is made up of valve body 11, dish plate 12, control lever 13, and agricultural-door is controlled dish valve 1 to yi word pattern barricade 10 and aqueduct 6 is fixed, and dish valve 1 afterbody is connected with equal diameter pipeline 6.When irrigation water is carried to Channel of Downstream 9 by aqueduct 6, control dish valve 1 regulating flow by agricultural-door, pipeline 6 is communicated with higher level's channel 8 and subordinate's channel 9.Valve body 11 part is built by laying bricks or stones in yi word pattern barricade 10.
In the middle part of aqueduct 6, in the middle part of channel 7, the piezometric level h of corresponding A-A, B-B section measured by setting pressure sensor 5 respectively
