Abstract

The utility model discloses a pedal water pump with plunger type structure. A pedal is used to drive a crankshaft connecting rod, so the arc line movement can be changed to the plunger reciprocating movement, and the water sucking and lifting can be realized. The suction lift of the utility model is 8 meters, the actual lift is 10 meters, and the flow quantity is 1-1.5 steres / hour. The utility model adopts a composite plunger, and a water sucking valve is reasonably matched with a water lifting valve; so the forced dead point of the movement is eliminated; the water sucking valve and the water lifting valve have fast and reliable function, so the water pumping efficiency of the pedal water pump is higher than the water pumping efficiency of the water press. The utility model has the advantages of good sealing and labor saving. In the same breath, the pedal water pump uses the pedal as the motive power, so the easy and comfortable operation can be realized; thereby, the pedal water pump can be used as ideal equipment which is suitable for the dispersive dweller of the remote region to realize manpower tap-water process.

Description

Pedal water pump

Technical field is the foot-operated pumping water device of a kind of manpower under the utility model.

Existing squeezer is a kind of pumping water device commonly used.But squeezer has only the suction journey, does not have lift, both made be short-range hoist to supply water by lower also can't solve.The piston of squeezer and piston rod are not moved in coaxial with cylinder body, and it is poor to seal, and leak, thereby influence water pumping efficiency.What squeezer used is the pressure of artificial arm, running hours, relatively effort.

The purpose of this utility model is to have developed a kind of foot-operated water pump, and is not only laborsaving, and can realize two, the water supply of three-storey building, increase lift, improved water pumping efficiency.

Pumping water device provided by the utility model, mainly by the plunger type pump housing, link rod piston mechanism and suction valve and blooming water valve constitute.The plunger type pump housing is made up of support body, cylinder body and combined piston.Combined piston is I-shaped circle wheel cock body, and cock body is two-layer up and down, is I-shaped, and every layer cock body all has the rubber seal disk up and down, clamps the plantation rubber sheet with steel disc again on it, and is to guarantee the double-layer seal of cock body, water-tight.The link rod piston mechanism comprises link rod and piston rod.Upper and lower end at link rod is equipped with selflubricating end joint shaft bearing, below the end joint shaft bearing stopper rod of taking over a job, four adjustable truckles that have ball bearing are equipped with in the both sides of piston rod, use as guiding and centering piston rod movement, the water pipe of blooming water valve and the suction sleeve of piston also keep on an axis at the homonymy of suction valve, the water outlet of suction valve and the water pipe of blooming water valve are the vertical position, and the spacing of suction valve and blooming water valve is not less than 0.5 meter.

Support body in the plunger type pump housing and cylinder body are fastening with nut, become one.80 millimeters of φ of support body, high 330 millimeters steel pipe is made, and cylinder body is 110 millimeters of φ, and high 210 millimeters, casting forms.Bent axle is contained in two bearing supports on the support body, the thigh on the pedal with the pin pin on bent axle.One side of bent axle adds two crank throws, turns the hole that the upper edge center line is made a call to 10 millimeters of 2 couples of φ, the stroke that moves in cylinder body in order to regulating piston.Cylinder center line 35 millimeter will be departed from the mounting point of bent axle, and crank throw is swung in 180 ° of scopes of cylinder center line one side.Bent axle and link rod join with the bolt of M10, and the link rod upper and lower end respectively is equipped with selflubricating end joint shaft bearing.The end joint shaft bearing of lower end and piston rod upper end have in the middle of the U type fork in 8 millimeters holes of φ, wear with 8 millimeters little axles of φ to connect.The lower end of piston rod connects combined piston, and four adjustable truckles that have ball bearing are equipped with in the both sides of piston rod, and its truckle is fixed by bolts on the support body.The suction valve body is identical with the blooming water valve body structure, is made by 80 millimeters of φ, high 105 millimeters steel pipe.Blooming water valve and suction valve are that the steel disc with the round steel of 12 millimeters of φ and 4 millimeters thick is welded into T-shaped, and bigger sealing rubber pad is housed below circular steel disc.The Pedal water pump saddle with bolton on the valve outer wall that pumps up water, adjustment height.

Because Pedal water pump adopts the said structure mode, so its working principle is as follows: when piston rises, because the function of end joint shaft bearing, make link rod drive bent axle, bent axle drives piston rod again and moves upward, and four truckles that ball bearing is housed guarantee that piston rod moves upward along cylinder center line, make and cause negative pressure of vacuum in the cylinder body of piston bottom, produce suction.This moment, blooming water valve was closed, and suction valve is opened, and the water in the pipe is inhaled into cylinder body, when piston rises to upper dead center, has been filled water in the cylinder body, stop to rise, and each point pressure balance in the water, suction valve cuts out by falling from gravity, finishing the suction action.Afterwards, because foot-operated effect makes piston begin to move downward, the water pressurized that is inhaled in the cylinder body backs down blooming water valve, the suction valve closure.When lower dead centre was arrived in piston motion, the water in the cylinder body all was pressed into lifting pipe, and each point keeps balance in the water, and blooming water valve falls by deadweight, has realized the function of pumping up water.Like this, piston to-and-fro motion under the driving of link rod, the function of finishing suction and pumping up water.

Advantage of the present utility model is as follows: because Pedal water pump has increased the function of pumping up water, can satisfy the water supply of dispersion resident two～three-storey building and the man-made irrigation of fritter terraced fields, four adjustable truckles are equipped with along the swaying direction of bent axle in the end joint shaft bearing of the link rod two ends employing selflubricating of Pedal water pump and piston rod both sides, so reduced friction, laborsaving.Use when operating in addition and ride, even continuous operation is also free and relaxed.Combined piston adopts the I shape double-layer seal, so water-tight.Inhale blooming water valve because of all stressed up and down.Event is rapider and reliable than squeezer switch, has improved the efficient of pump water greatly.In addition, combined piston is along coaxial moving linearly, makes that Pedal water pump is durable, the life-span is long.
