Description
Technical field
The utility model belongs to agricultural production cultivation field, specifically, is that a kind of head-tank gravity irrigation drives closed system.
Background technology
In hills area, there is many high-level reservoirs, for saving the energy, preferentially adopting gravity irrigation, both utilized high-level water source gravity flow to be delivered to lower field by the road and irrigated.When the water level of head-tank lower than ground outside pond and pond does not have a pre-buried delivery port time, current need be driven to reach from stream mode by external force.Traditional solution: (1) pipe laying pump water suction on the pipeline of limit, pond drives; (2) connect submersible pump in pipeline water sucking mouth to drive; (3) driving with vacuum pump suction lower than on water level in water pool place pipeline.Above scheme has following deficiency: (1) needs near head-tank, set up circuit or provide diesel powered, and investment cost is high; (2) water pump be installed on pipeline increases resistance to water-flow; (3) dismantle loaded down with trivial details, portability is poor; (4) not there is air emptying function of cutting off the water supply, be unfavorable for the antifreeze management of pipeline.
Utility model content
In order to solve the problem, the utility model proposes a kind of head-tank gravity irrigation and driving closed system, can effectively drive current to reach from stream mode, realization is cut off the water supply emptying.
A kind of head-tank gravity irrigation of the utility model drives closed system, comprises hand water pump, main line, intake and exhaust pipeline, air inlet and exhaust valve, floating drum, water suction filtering head.
Described hand water pump is arranged on support, is supported by support.The water sucking mouth of hand water pump is in parallel with main line respectively by the connecting line being provided with the first valve with outfall.On main line, between the junction with main pipeline, the second valve is installed in hand water pump water sucking mouth and outfall.Intake and exhaust pipeline is provided with air inlet and exhaust valve and the 3rd valve.Main line one end is as suction side, and the other end is as discharge ends.End, suction side is provided with filtering head, and filtering head is connected with the floating drum be placed on the reservoir water surface by lifting rope.
When the utility model head-tank gravity irrigation drives closed system work, make the first valve be in opening, the second valve and the 3rd valve are in closed condition.Shake hand water pump subsequently and the water in reservoir is sucked main line by connecting line.When after waterflow stabilization flowing in connecting line, slowly open the second valve, close the first valve simultaneously, make the current in reservoir enter main line by the water inlet end of main line, and arrive in irrigation conduit through the water side of main line; Realize the driving of current thus.After irrigation terminates, open air inlet and exhaust valve, utilize the pressure differential in pipeline, the quick air inlet of air inlet and exhaust valve, to realize the closedown of pipeline current and emptying, human factor can not only be avoided to open by mistake valve and to lose the water yield by letting out under reservoir, the antifreeze management of pipeline emptying in winter can also be conducive to.
The utility model has the advantage of:
1, the utility model head-tank gravity irrigation drives closed system, can realize manpower driven by shaking, have air emptying function of cutting off the water supply, simple and reliable, good portability; Additionally do not increase resistance to water-flow, without the need to electric power, in the head-tank gravity irrigation situation of unregulated power condition, can effectively drive current to reach from stream mode, realization is cut off the water supply emptying.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
The utility model head-tank gravity irrigation drives closed system, comprises hand water pump 1, main line 2, intake and exhaust pipeline 3, air inlet and exhaust valve 4, floating drum 5, water suction filtering head 6.
Described hand water pump 1 is arranged on support 7, is supported by support 7.Hand water pump 1 is in parallel with main line 2 by connecting line.Concrete mode is: the water sucking mouth of hand water pump 1 is communicated with transparent hose A8, transparent hose B9 one end respectively with outfall; Transparent hose A8 is connected the first valve A10, the first valve B11 with the other end of transparent hose B9 respectively by snap joint; First valve A10 is communicated with horizontally disposed main line 2 by pipeline with the first valve B11, controls discharge in transparent hose A8 and transparent hose B9 by the first valve A10 and the first valve B11.Described intake and exhaust pipeline 3 is vertically arranged, and is communicated with main line 2.On above-mentioned main line 2, at the first valve A9 and between the first valve B10 and main line 2 connectivity part, the second valve 12 is also installed, is controlled the discharge in main line 2 by the second valve 12.Described intake and exhaust pipeline 3 end is provided with air inlet and exhaust valve 14; Intake and exhaust pipeline 3 is provided with the 3rd valve 13, controls throughput in intake and exhaust pipeline 3 by the 3rd valve 13.
Above-mentioned main line 2 is near one end of the first valve A10 as suction side, and one end of close first valve B11 is as discharge ends; Suction side stretches to columns base; Discharge ends stretches on the irrigation conduit in field; And need ensure that air inlet and exhaust valve 14 is higher than reservoir peak level.The end, suction side of main line 2 is provided with net formula water suction filtering head 6, prevents foreign material from sucking main line 2 thus.Water suction filtering head 6 is connected with the floating drum 5 be placed on the reservoir water surface by lifting rope 15, can with water surface synchronization lifting, ensure that suction side is suspended from underwater certain distance all the time, namely suction side and columns base distance are necessarily, avoid water sucking mouth to contact impurity at the bottom of reservoir pond and cause blocking.
When the utility model head-tank gravity irrigation drives closed system work, first, ensure that each valve on irrigation conduit is in opening, the first valve A10 and the first valve B11 is in opening, and the second valve 12 and the 3rd valve 13 are in closed condition.Shake hand water pump 1 subsequently the water in reservoir is sucked by transparent hose A8, and flow into main line 2 by transparent hose B9.Can judge whether current pass through through transparent hose A8 and transparent hose B9, when after waterflow stabilization flowing, slowly open the second valve 12, close the first valve A10 and the first valve B11 simultaneously, make the current in reservoir enter main line 2 by the water inlet end of main line 2, and arrive in irrigation conduit through the water side of main line 2; Realize the driving of current thus.After irrigation terminates, open air inlet and exhaust valve 14, utilize the pressure differential in pipeline, the quick air inlet of air inlet and exhaust valve, intake and exhaust pipeline 3 is communicated with ambient atmosphere with the current of main line 2 junction, these downstream, junction current are made to continue self-pressure, let out for 2 times by main line, upper water flows back to stream reservoir, to realize the closedown of pipeline current and emptying, human factor can not only be avoided to open by mistake valve and to lose the water yield by letting out under reservoir, the antifreeze management of pipeline emptying in winter can also be conducive to.
Consider antitheft, peasant household realizes transparent hose A8, transparent hose B9 and the dismounting between the first valve A10, the first valve B11 by snap joint, and then realizes being separated between hand water pump 1 with main line 2.Transparent hose A8, when using, is connected with the first valve A10, the second valve B11 by snap joint with transparent hose B9 by next time.
