Abstract

The utility model discloses a multipurpose water pump which can be driven electrically and manually. The problems that at present ordinary electric water pumps need water for irrigation and a bottom valve, and the ordinary electric water pumps can not be used after power is cut off are solved. The utility model has the advantages of energy saving and multifunction in one machine, and the multipurpose water pump can be used for life, industrial and agricultural production and fire protection. Particularly, a favorable device is provided for wide villages, towns and rural areas for solving the problem of domestic water, and the multipurpose water pump has great significance in reducing diseases, improving people's health level and popularizing tap water in rural areas. Furthermore, the multipurpose water pump can be used as a vacuum pump for pumping vacuum. The multipurpose water pump can be used as an inflation pump for inflating household vehicles according to requirements. The multipurpose water pump is light and convenient.

Description

Multipurpose water pump

The present invention is water work in the daily life.

Before the present invention made, known electric water pump such as electric centrifugal pump etc. can only rely on electronic drawing water, and drew water in case have a power failure just can't turn round; Moreover, need artificial toward the interior perfusion of pump diversion, cumbersome before drawing water; Simultaneously, at intake pipe one end bottom valve must be set, otherwise can't fill with diversion.For above-mentioned reasons, caused the electric water pump effect single, used trouble, energy consumption increases, and working efficiency reduces.Particularly under the situation of vast rural area frequent outage at present, the people's life process water supply is subjected to very big influence, has limited popularizing of it.And popularity rate higher handlance pump in rural area exists that surface friction drag is big, physical output big, at the bottom of the work efficiency, weakness such as labor intensity height, press for update.

The present invention seeks at the problems referred to above, a kind of newly-designed multipurpose water pump is provided.Draw water but make it when electricity is arranged electricity consumption, can not draw water with the people is hand or foot-operated when having electricity.Solve family or groupuscule domestic water problem preferably.In addition, according to development of the situation, under the situation about also not catching up with in vast village economic condition, it is also less to choose refrigerator preservation food person accounting example, the vacuum bagged instrument is fresh-keeping will to have great practical value and promotional value in vast rural area, yet, but suffer from no vaccum-pumping equipment in the rural households, hindered this technical development.The present invention only need change the several valves working state, also can be the vacuum bagged food fresh keeping a kind of easy vacuum pumping device is provided.In case of necessity, also can change the valve working state, make it to become inflating pump, be inflations such as family's bicycle commonly used, motorcycle, ball, air-blast atomizer.

The present invention has designed a kind of manpower diaphragm pump, available foot-operated also available driven by shaking; And with the manpower diaphragm pump and electric water pump is ingenious combines, the turnover water pipe that makes it two pumps is coordinated mutually, promptly diaphragm pump does not exert an influence to it when electronic drawing water, and motor-drive pump did not exert an influence to it when the back manpower that has a power failure drew water, and remedies weakness separately mutually.The present invention takes below manpower diaphragm pump shell a side to open a hole, weldering the preceding paragraph water pipe, and make the other end of this section water pipe be connected to centrifugal pump outlet pipe place, simultaneously, respectively establish an one-way cock up and down in the connecting part of water pipe 8 and outlet pipe 9, diaphragm pump shell and strut fixation are on motor housing.Again in electric water pump inlet device valve 14, in outlet

port device valve

12,13,15.

Advantage of the present invention is, and is simple in structure, designs ingenious, the volume small volume and less weight, beautiful shape is coordinated, electronic manpower dual-purpose, have multiple function, there is electric power or not does not influence feedwater, simultaneously, need not pour into diversion during electronic drawing water yet, economize, reduce fluid resistance except bottom valve, saved energy consumption, improved efficient, solved a great problem of domestic water preferably, popularized domestic running water for rural area, vast small towns a kind of good equipment is provided.In addition, but also double as vacuumizes, and makes inflating pump, makes its one-object-many-purposes.Cost of production is not high, and market potential is very big, and bigger economic benefit and social benefit are arranged.

Fig. 1 is a structural representation of the present invention.

Fig. 2 is a partly theory diagram of automatic control of liquid level.

Be further described below in conjunction with accompanying drawing: when drawing water with manpower is foot-operated, step on treadle 3, treadle passes to diaphragm pump shadoof 7 by pole 4 with power, drives barrier film upwards, the diaphragm pump 5 inner vacuum that form, extraneous water source sucks from intake pipe under atmospheric pressure, enters diaphragm pump by electric water pump 1, one-way valve 11, water pipe 8, when unclamping pin, diaphragm pump is extruding downwards under the elastic force of spring 6, water in the pump is discharged from water outlet 9 by one-way valve 10, finishes an overall process.During electronic drawing water, with foot-operated moving treadle for several times, with the air emptying in the centrifugal pump, starting pump motor 2 then can draw water earlier.Electronic drawing water partly also is provided with automatic liquid level detection circuit, in case the electrical network incoming call is anhydrous as the pond, can starts water pump automatically and draw water, and takes out full back autostop.In the time of need vacuumizing; Open valve 12, ambient air enters in the electric water pump, and water flows back to the water source along pipe in the pump, opens valve 13 again, the water of water inlet is drained, and throttle down 14,12 places put rubber pipe at valve, can vacuumize with the manpower diaphragm pump.In the time of need inflating,

open valve

12,13, the water in pump and the water inlet is bled off, step under the manpower pump number, surplus water in the pump is drained, throttle down 15 puts the air guide rubber pipe at valve 13 places, and stepping the manpower pump can inflate.

Claims

1, a kind of multipurpose water pump is characterized in that:

A. manpower pump and electric water pump are combined into one;

B. two pump inlet and outlet pipe lines are shared mutually;

C. be provided with valve 12,13,14,15 at the water intake and the water outlet place of pump.

2,, it is characterized in that it is that manpower does not need to change artificially any mechanism between pump and the pump when driving that water pump is converted to electric power or power conversions at manpower by the described multipurpose water pump of claim 1.

3, by claim 1,2 described multipurpose water pumps, it is characterized in that automatic level controling mechanism by level sensing detections, signal amplification, actuator and power supply partly form.
