A kind of rivers and canals gravity flow pump described in the utility model is characterized in that rotation control mechanism comprises crank and water wheels, and crank and water wheels link, and piston and crank are hinged.Crank be "
" type, water wheels are sleeved on the two ends of crank, Hinged piston on the middle beam of crank.Sleeve is set on the water outlet, and piston is arranged in the sleeve.Hinged second loose-leaf on water outlet, second loose-leaf is opened along the water outlet direction is unidirectional, and when piston advanced, second loose-leaf was opened water outlet, when piston is pulled back, the closed water outlet of second loose-leaf.Filter screen taken in the water intake first line of a couplet of casing.
The beneficial effect that the utility model had is:
The utility model crank be "
" type, water wheels are sleeved on the two ends of crank, and Hinged piston on the middle beam of crank sets out the mouth of a river on casing, and piston is arranged in the water outlet, and the current of water intake drive water wheels and rotate so that the crank rotation is ordered about piston and moved reciprocatingly in water outlet; Through hole is set on piston, and on piston hinged first loose-leaf, first loose-leaf is opened along the water outlet direction is unidirectional, first loose-leaf is closed through hole when piston advances, when pulling back, opens in piston through hole, as much as possible when this design can make piston advance in sleeve water is ejected, and in the backhaul process of piston, can make water in a canal mend sleeve rapidly, reduce the backhaul pressure of piston simultaneously.Thus the utility model is placed in the rivers and canals, as long as water in a canal flows, can drives water wheels and rotate, the to-and-fro motion of piston can go out water pump, need not to move by external force is auxilliary reliable the and energy-conserving and environment-protective of power supply.
2. UNICOM's sleeve on the water outlet, piston is arranged in the sleeve, hinged second loose-leaf on water outlet, second loose-leaf is opened along the water outlet direction is unidirectional, and when piston advanced, second loose-leaf was opened water outlet, water in a canal can be pumped smoothly, when piston was pulled back, the closed water outlet of second loose-leaf prevented that the water in a canal that has pumped from refluxing from the water outlet suck-back.
3. the utility model is provided with filter screen at water intake, can effectively intercept the solid particle in the rivers and canals, avoids injuring the mechanism in the pump housing, reduces the generation of fault, has effectively prolonged working life.
4. the utility model is reasonable in design, compact structure, and fabricating cost is low, suitable penetration and promotion and industrialization volume production.
