The basic thought of the utility model technical solution problem is: by add tap water energy water pumper in described system, solved the difficult problem that must water could be risen to eminence by electric power, by the water energy switch room of connecting at described piston type water pumper front end, and booster of water energy switch room front end series connection, when tap water passes through booster, tap water is carried out supercharging, tap water after the supercharging enters water energy switch room inside, promoting wheel disc then rotates, the motion of wheel disc drivening rod, connecting rod promotes piston and moves reciprocatingly in piston cylinder, thereby waste water is risen to the storage tank of eminence from the header tank of lower, wastewater collection is got up, so that unified the utilization.
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the utility model protection.
See also Fig. 4, the tap water that Fig. 4 provides for the utility model embodiment can the water pumper structural representation.
Wherein 1 is tap water water inlet direction, and 2 is connector, and 3 is booster, and 4 are the wheel box, 5 is wheel disc, and 6 are water energy switch room, and 7 is in the supercharging setting, and 8 is depressor area, 9 is connecting rod, and 10 is water (flow) direction, and 11 is the running water outlet direction, and 12 is piston, 13 is reservoir chamber, and 14 is the water pump head, and 15 is piston cylinder, and 162 is unidirectional suction valve, 161 is the single slope drainage valve, and 17 for waste water sucks direction, and 18 is booster, and 19 are waste water discharge direction, 20 is union, and 21 for dashing bucket, and 22 is anallobar.
The utility model provides a kind of tap water can water pumper, under the situation that is implemented in consumed power not, waste water is risen to eminence from lower.
The utility model is divided into three ingredients:
1, booster (refer to the pressure supercharging of tap water and the device of repressurize);
2, water energy switch room (referring to that the water of tap water can convert the device of mechanical energy to);
3, piston type water pumper (referring to mechanical water plug).
Described booster 3 can link to each other by switch room 6 with described water; Booster 3 is funnel-form, one end diameter is bigger, other end diameter is less relatively, and current flow into from the bigger end of diameter, flows out from the less end of diameter, flow into anallobar 22, flow along water (flow) direction 10, thereby realize supercharging, the difference of two ends diameter can set up on their own according to the tap water flowing pressure, as diameter difference is three times, and then booster 3 can increase by three times with the tap water flowing pressure.
Described water can link to each other with described piston type water pumper by switch room 6;
Described water can be adorned and change chamber 6 and be specially: wheel box 4, wheel disc 5 and seal cover;
Described wheel disc 5 is arranged on described box 4 inside of taking turns, and described seal cover is arranged on described wheel disc upside; Described water can be respectively arranged with water inlet and delivery port by switch room 6; Tap water enters water energy switch room 6 from water inlet, flow out and utilize from delivery port, tap water water inlet direction 1 shown in the figure is a water inlet position, running water outlet direction 11 is the delivery port position, and the position that water energy switch room 6 and delivery port join is a depressor area 8, and current can come out to enter into depressor area 8 by switch room 6 from water, because the long-pending current area than water energy switch room 6 of the water flow section of depressor area is big, so can reduce pressure, otherwise, be not suitable for utilizing because water flow pressure is too big.
An end of connecting rod 9 links to each other with described wheel disc 5 in the described piston type water pumper, and tie point is the arbitrfary point in non-wheel disc 5 centers of circle, and what wheel disc 5 outer rings were provided with the wheel dentation dashes bucket 21.Half that preferably tie point is arranged on described wheel disc 5 diameters is with on the upper/lower positions.Dashing the ratio of bucket 21 to the length in wheel disc 5 centers of circle and tie point to the length in wheel disc 5 centers of circle is the multiple of repressurize, if tie point is near wheel disc 5 outer rings, water impact is dashed bucket 21 meetings and required great effort very much, and promptly the supercharging multiple is too little, and it is slow to cause wheel disc 5 to rotate; If tie point is near the home position of wheel disc 5, the supercharging multiple is very high, and wheel disc 5 rotating speeds are very fast, but the stroke of connecting rod 9 is too little, thus cause the stroke of piston 12 of connecting rod 9 other ends too little, and can not extrude or suck more waste water.
Described piston type water pumper specifically comprises: wheel lid, connecting rod 9, piston 12, piston cylinder 15, water pump head 14, water sucking mouth and delivery port;
The other end of described connecting rod 9 links to each other with described piston 12 and places in the piston cylinder 15;
Described water pump head 14 links to each other with described piston cylinder 15;
Described water sucking mouth and delivery port are arranged on the described water pump head 14.
The utility model tap water can be connected on the water pipe of household tap water inlet side by water pumper, open running water switch in any place or many places and use the work that moves when water pumper just waits in this period of tap water, tap water with certain pressure is at first by booster 3 superchargings, dash bucket on the water impact wheel disc 5 after the supercharging, dash the stressed back of bucket and drive wheel disc 5 rotations, the wheel disc 5 of Zhuan Donging is this power repressurize twice simultaneously, drive piston 12 by connecting rod 9 then and do continuous oscillation cycle motion, wheel disc 5 revolutions are moving to be done once to move back and forth once circle piston 12, thereby finish the suction and draining (or draining and suction) motion of one-period, suction is that the waste water with lower is drawn onto in the water pumper reservoir chamber 13, draining is to discharge reservoir chamber 13 after the water in the reservoir chamber 13 is pressed, thereby waste water is risen to eminence from lower.
Further, on delivery port on described piston type water pumper delivery port and the water energy switch room 6 and water inlet, all be provided with connector 2 in order to optimize the utility model scheme.Connector 2 is the devices that are connected with tap water turnover pipe, waste water turnover pipe, and its function is to guarantee to be interconnected to a total system, guarantee that tap water is not contaminated, guarantee that tap water can the normal effectively work of water pumper.The connector 2 of described water energy switch room 6 water inlets links to each other with described booster, and described union 20 (that end that is connected with tap water turnover pipe, waste water turnover pipe) diameter from inside to outside reduces gradually, and becomes stepped.Become stair-stepping connector to take over end and can make that connection is more firm, can avoid seepage, guarantee that tap water can the normal effectively work of water pumper.
Be respectively arranged with unidirectional suction valve 162 on described piston type water pumper water sucking mouth and the delivery port, single slope drainage valve 161, unidirectional suction valve 162 and single slope drainage valve 161 are one way valve, make waste water not go out from the water sucking mouth, can not come in from delivery port.
The delivery port of piston type water pumper also can carry out a supercharging to waste water, because the diameter of reservoir chamber 13 is more much bigger than the diameter of delivery port, so there is enough pressure that waste water is risen to eminence.
