Description

Multifunction manpower pump

The utility model belongs to the pressure water pump class, relates generally to by manually driven household pressing water pump and field irrigation pump.

At present, widely used pumped well aspect China's industrial or agricultural, its principle is: through leverage rubber piston is pumped with manpower in the well casing of sealing, make the well casing of sealing form vacuum, cause negative pressure, to force the fluid into well casing, by rubber piston, fluid is ejected again.Pumped well in use has narrow limitation, promptly only has the suction journey, does not have lift, has therefore limited its wider use.Drainage and irrigation equipment in the existing farmland, beyond supporting, generally be to drive drainage and irrigation equipment with bavin, petrol engine, because the price of bavin, petrol engine is more expensive, the cost height, for small size farmland and vegetable field etc., the way fortune water of still choosing and pushing away, carrying on the shoulder, so not only efficient is low, and labor intensity is big.

The purpose of this utility model provide a kind of promptly have inhale journey, have a lift again, and cost is low, efficiency is high, can be widely used in the manpower pump of industrial and agricultural production and life usefulness.

The utility model is the water intake that is communicated with by telescopic cover, valve, with valve, water outlet and is linked to each other with hand lever with an end by the hinged hand lever of frame, the connecting rod that the other end is connected with flange plate is formed, telescopic cover is connected with flange plate by flange ring, the flange plate and the frame of telescopic cover one side are fixed, and be communicated with valve, the flange plate of opposite side links to each other with connecting rod.

The utility model telescopic cover can be 1 to be used separately, also can be two in parallel uses.Described hand lever can be the push-and-pull rod-type, also can be to jump pressure bar type, and can also be rocker type.Above-mentioned valve is that two one-way valves are in series, and is communicated with telescopic cover in the middle of the connection of two one-way valves.In push-and-pull rod-type hand lever, two connecting rods, one end is hinged, and the other end links to each other with hand lever with moving flange plate respectively.

The utility model does not need electric energy and bavin, petrol engine to drive, and only needs manual operation, and cost is low, can play the effect of general small pump, and its suction lift or lift are greater than 6 meters, and flow can reach 10 ^M3/ hour, and do not need water, the remote mountain areas is reached the regional excellent in being suitable for of not energising.The utility model spraying pesticide can spray simultaneously for many shower nozzles, the saving of labor, save time, laborsaving, spray effective.And can be used as safe fire-fighting equipment, machine and vehicle flushing, the eliminating of oiling, poison gas, venom etc.

The utility model is described in further detail below in conjunction with accompanying drawing:

Fig. 1 is a push-and-pull rod-type schematic diagram of the present utility model;

Fig. 2 is the structure principle chart of the utility model valve;

Fig. 3 is that the utility model is jumped the pressure bar type structure principle chart;

Fig. 4 is the utility model rocker type structure principle chart;

Among the figure: 1 flange plate, 2 flange rings, 3 telescopic covers, 4 flange plate, 5 water outlets, 6 valves, 7 connecting rods, 8 connecting rods, 9 hand levers, 10 guide sleeves, 11 frames, 12 water intakes, 13 flange rings, 14 return pulleys, 15 one-way valves, 16 one-way valves, 17 depression bars, 18 depression bars, 19 connecting rods, 20 connecting rods, 21 rocking bars, 22 connecting rods.

When hand lever 9 pushes hard, drive telescopic cover 3 by connecting rod 8, connecting rod 7 and flange plate 1 and be stretched, form negative pressure in its chamber, under the ambient pressure effect, liquid will enter into the cavity of telescopic cover 3 by the one-way valve 16 in water intake 12 and the valve 6.When hand lever 9 spurred backward, telescopic cover 3 was compressed, and the liquid in its cavity will be discharged by one-way valve in valve 6 and the valve 15 and water outlet 5.Flange plate 4 is fixedlyed connected with frame 11, between flange plate 1 and the frame 11 return pulley 14 is arranged, and return pulley 14 plays a supportive role on the one hand, the frictional force in the time of can reducing flange plate 1 on the other hand and move.At the opposite side of flange plate 1, also fix a telescopic cover by flange ring, when pushing away before the hand lever, can realize the difference water inlet and outlet of two telescopic covers with post-tensioning.Guide sleeve 10 play the guiding role on the one hand, plays a supportive role on the other hand.

In Fig. 3, hinged with frame in the middle of depression bar 17 and the depression bar 18, an end of connecting rod 19 and connecting rod 20 links to each other with depression bar 18 with depression bar 17 respectively, and the other end is connected with corresponding flange plate.When depression bar 18 is depressed, by connecting rod 20 telescopic cover is compressed, realize draining, when depression bar 18 was mentioned, telescopic cover was stretched, thereby can realize suction.The effect of depression bar 17 is with depression bar 18, and two depression bars can use separately, also can use simultaneously.

In Fig. 4, rocking bar 21 intermediate projections, and link to each other with connecting rod 22, rocking bar 21 two ends have bearings respectively, when rotating rocker 21, by the rocking bar axial projection, drivening rod moves up and down, thereby the flange plate that links to each other with connecting rod 22 is moved up and down, drive stretching, the compression of telescopic cover, realize the purpose of suction, draining.

Above-mentioned three embodiments of the present utility model have all utilized lever principle, save time during operation, laborsaving, and are now by prototype experiment, respond well.
