Five, embodiment
Pipe duct needs special manufacture, and pipe duct should have certain intensity and rigidity, and water-tight, can also ensure certain spatial form, can have enough discharge capacity, meets the requirement of irrigating flow, for reducing investment, can adopt plastic tube; Pulley preferably adopts the pulley of plastic material, both ensure that enough intensity and rigidity, again weight reduction as far as possible, dexterous convenient; Pull rope can adopt thin tightwire or other have certain tensile strength and flexible material to make; Plug valve according to the section configuration of pipe duct, can be bought or oneself making on scene.Power set are commercially available; Gearbox also can according to speed change request oneself customization or commercial.
When the present invention works, first according to Fig. 1, device is fixed, because power transmission shaft creates rotation by gearbox under the effect of power set, power take-off and pull rope link together, so, now, pull rope can produce migration, moves around the pulley fixed on the ground, because pull rope is connected with plug valve, so, plug valve can be driven to migrate; After current are flowed out by feed pipe, directly inject pipe duct, flowed to furrow tail or ditch tail direction by pipe duct, due to the barrier effect of plug valve, water will overflow pipe duct by plug valve, and enter field; Pipe duct is laid on embanked field or ditch Tanaka; Because there is certain gradient in embanked field or ditch field, namely higher end is low, so, pipe duct also can higher end low, namely pipe duct also has certain gradient, and equal with the gradient in embanked field or ditch field; Because feed pipe is laid in higher one end, face, field, when being transported to after inside pipe duct by irrigation water, under gravity, current can flow to the lower one end of pipe duct by one end that pipe duct is higher, like this, current can along the gradient direction flow forward in embanked field or ditch field in pipe duct, in the place running into plug valve, owing to matching the barrier effect of valve, current can not again along pipe duct flow forward, can only overflow pipe duct, enter embanked field or ditch field, supply is irrigated and is used.
In order to resistance during balance traction plug valve, increase work efficiency, the irrigation work of two pipe ducts can be carried out simultaneously, and one pipe duct from pipe duct stem (as the plug valve in pipe duct a a), and another pipe duct starts working (the plug valve b as pipe duct b) from afterbody, such two plug valves are all subject to the impulse force of current, to alleviate the output energy of power take-off; As: plug valve a can in pipe duct a, rearwardly evenly, exactly moved by stem, current in pipe duct a are due to the stop of plug valve a, can automatically, equably in the stem along embanked field or ditch field rearwardly direction, gone out by overflow in pipe duct a, the current in pipe duct a are evenly supplied water to embanked field or the overflow of ditch field going up on the way of pipe duct a; And now plug valve b can in pipe duct b, evenly, exactly moved to stem by afterbody, current then in pipe duct b are due to the stop of plug valve b, can automatically, equably at the afterbody along embanked field or ditch field on stem direction, gone out by overflow in pipe duct b, the current in pipe duct b are evenly supplied water to embanked field or the overflow of ditch field going up on the way of pipe duct b.Like this, pipe duct can control the duty of each point evenly, exactly, realizes automatic, accurate irrigation.
According to parameters such as water pressure sizes in irrigation program, irrigation norm, embanked field specification, irrigation uninterrupted and aqueduct, calculate irrigation water capacity, plug valve migration velocity, gate valve aperture by inlet channel is arranged adjusts the uninterrupted by turbo-power output device, plug valve translational speed is made just in time to be applicable to the needs of duty, simultaneously, when plug valve moves, can automatic average rate move, this ensures that there the water yield poured into everywhere equal, achieve the requirement of uniform irrigation, make irrigation even, the water yield obtained everywhere is identical.
In order to make irrigation as far as possible continuously, in system irrigation process, by manual type in advance lower two embanked fields or two ditch Tanakas, laid pull rope and pulley in advance, after upper two furrow or two have irrigated through furrow, the device that outputs power has moved on to the next position, and be connected with thin tightwire, like this, a new land for growing field crops pipe duct automatic irrigation system is defined again, under power take-off effect, automatically the irrigation in this embanked field or ditch field can be completed again, so, go round and begin again, until complete all irrigations.
The present invention has the following advantages:
(1) energy automatic irrigation, reduces labour intensity
This system utilizes power set, control irrigation system and automatically complete irrigation, eliminates the work of people, reduce labour intensity in irrigation process.
(2) pour water evenly, accurately
Under normal circumstances, the rotating speed that power set export is stable, thus achieve the constant speed rotation of power take-off, then the constant speed movement of plug valve is achieved, in addition the discharge in aqueduct is equivalent, so it is constant for feeding field flow everywhere, achieves the uniformity and accuracy of pouring water everywhere.
Design principle of the present invention is unique, solve the prevailing surface irrigation of current China uneven, water yield waste serious problems, no matter in theory, technically, or the aspects such as serviceability, all create qualitative leap, China's irrigation water using efficiency and the surface irrigation uniformity can be improved to a great extent.
