Abstract

The utility model discloses an improved water draw-off pump, comprising a close cylinder body, two sets of water inlet and outlet valves, a piston, a connecting rod, water inlet and outlet pipelines, a bracket, a water through pipe which is provided with multiple segments and can be connected, and a power mechanism (can be hand-operated, foot pedal, electric, etc.) which is matched with the water through pipe. The improved water draw-off pump has wide practical range, and is especially suitable for drainage and irrigation in field with small area in countries or pumping underground domestic water for peasant households to use.

Description

Convenient water draw-off pump

The utility model relates to a kind of improved Water draw-off pump, but the Water draw-off pump of higher continuous water supply of particularly a kind of efficient and conveniently moving.It mainly draws surface water or certain depth underground water usefulness for field irrigation or sphere of life.

Existing Water draw-off pump is made up of opening cylinder body, connecting rod, piston, single valve door (water inlet) and whole water inlet siphunculus etc.Its working principle is, piston is during by the connecting rod pull-up, and water is entered in the cylinder by inlet valve, then piston is pushed, at this moment inlet valve is closed, and the water in the cylinder promptly flows out through the opening of cylinder body by the minor valve in the piston (if piston is to be become by the rubber leather, then minor valve need be set).From the working principle of this Water draw-off pump as can be seen, it is unidirectional acting, and water supply is interrupted, and its efficient is lower, and in addition, this Water draw-off pump generally is to be fixed in the somewhere to be used to draw underground water usefulness, and using scope is extremely restricted.

The purpose of this utility model is with regard to the deficiency of above-mentioned existence, design a kind of can two-way work doing when piston is moved up and down in cylinder body, efficient height, reciprocation cycle continuous water supply and structure be convenient to the Water draw-off pump that moves flexibly.

Main points of the present utility model are, cylinder body is taked enclosed construction, and valve is that two groups of water inlet and outlet valves are formed, and the water inlet siphunculus is that the mountable garden of more piece pipe is formed (its length can be determined according to the degree of depth that draws water).The visible accompanying drawing 1 of its working principle, like this, by sealed cylinder body, connecting rod, piston, inlet and outlet pipe lines, two groups of water inlet and outlet valves, the mountable water inlet siphunculus of more piece and supports and the power mechanism (can be hand, foot-operated or electrodynamic type etc.) that matches have just constituted the utility model.

Compare with former Water draw-off pump, the utlity model has following advantage, one, efficient is two times of former Water draw-off pump and supplies water continuously, two, its water inlet siphunculus is that more piece is mountable and support is housed, and can move use flexibly.Present vast rural area is owing to carried out responsibility system, the field area that each household is cultivated is all less, the irrigation apparatus that waters has become a big problem, the water pump each household is not afforded to do economically, and wooden waterwheel and bailing bucket efficient are lower, therefore, have designed the utility model on the basis of former Water draw-off pump, it can adapt to current peasant household field irrigation usefulness preferably, also can be used for sphere of life and draws water.

Below, in conjunction with the accompanying drawings the utility model is further set forth.

Fig. 1 is a working principle schematic representation of the present utility model.

Fig. 2 is schematic representation of the present utility model (broken section).

With reference to figure one, its working principle be, when piston is up moved by the connecting rod pull-up, water enters cylinder body by the bottom right valve, at this moment lower-left valve and upper right valve closing, the water of piston top cylinder body flows out by upper left valve, when piston pushed, then water entered cylinder body top, and the water of bottom is then discharged by the lower-left valve.Piston up and down reciprocatingly circulates, then water is discharged continuously.

With reference to Fig. 2, intake pipe (1) is communicated with outlet conduit (2) and cylinder body (3), two inlet valves (4) are positioned on the joint of intake pipe (1) and cylinder body (3), and two flowing water Valves (5) are positioned on the joint of outlet conduit (2) and cylinder body (3).Piston (6) is contained in the cylinder body (3) and with connecting rod (7) and is connected, connecting rod (7) links by the loam cake central small hole and the power mechanism of cylinder body (3), (8) be water outlet, water intake (9) links with the mountable water inlet siphunculus of more piece, and support is contained in the bottom of cylinder body.

Claims

1, a kind of Water draw-off pump of forming by cylinder body, piston, connecting rod, valve, water inlet siphunculus, it is characterized in that: this Water draw-off pump cylinder body is closed, cylinder body and inlet and outlet pipe lines connection place are equipped with two groups of water inlet and outlet valves up and down, support is equipped with in the bottom of cylinder body, and the water inlet siphunculus is that the mountable garden of more piece pipe is formed.
