Before the novel electric power machine is used, technicians adjust and set the time of the power supplies output by the 3 and 4 pins of the two sets of time control switches A1 and A2 according to requirements, for example, six power supplies are output by the 3 and 4 pins of the time control switch A1 every day, 15 seconds of power supply is output every hour every time and enters the power supply input ends of the positive and negative poles of the motor speed reducing mechanism M (the total 90 seconds of the power supplies are output for 6 times), the power output shaft of the motor speed reducing mechanism can act on the sliding block 54 through the screw rod 52, the sliding block 54 moves from the front top dead center of the supporting plate 51 to the bottom dead center) every hour, for example, after 7 hours every day every time (the power supplies are respectively output by the next time control switches A1 and A2), the six power supplies are output by the 3 and 4 pins of the time control switch A2, 15 seconds of power supply is output every hour and enters the power supply, the power output shaft of the motor speed reducing mechanism can act on the sliding block 54 through the screw rod 52, so that the sliding block 54 moves from the front lower dead point to the upper dead point of the supporting plate 51. ).

This is novel, time switch A1's 3 and 4 feet export at every turn in the time of 15 seconds power entering motor reduction mechanism M plus-minus two poles power input end, motor reduction mechanism M gets electric its power output shaft anticlockwise drive lead screw 52 and rotates, and then lead screw 52's internal thread acts on sliding block 54's internal thread, sliding block 54 drives inlet tube 55 and water pipe 3 descending height gradually, when behind control switch A1 output six times plus-minus two poles power, sliding block 54 just drives inlet tube 55 down to the dead point, bottom interval is close to in inlet tube 55 left side lower extreme and the water tank. During inlet tube 55 moved from top to bottom, the booster pump of constant voltage variable frequency water supply unit body intake end just can effectively be drawn upper strata to interior lower floor in the water tank to reach in the water between the two gets into the user's pipeline (inlet tube 55 left lower extreme can effectively draw lower floor's water). In the time that 3 and 4 feet of time switch A2 output power for 15 seconds at every turn and get into motor reduction gears M negative and positive two poles of the earth power input end, motor reduction gears M's power output shaft drives lead screw 52 clockwise and rotates, and then the internal thread of lead screw 52 acts on the internal thread of sliding block 54, sliding block 54 drives inlet tube 55 and water pipe 3 rise gradually, when behind control switch A2 output six times negative and positive two poles of the earth power, sliding block 54 just drives inlet tube 55 and goes up to the dead point, upper portion interval is close to in inlet tube 55 upper end and the water tank (the inlet tube upper end is located the lower position of upper strata under water in the water tank, inlet tube 55 upper end lower extreme is intake. The inlet tube 55 is by during the supreme motion down, the booster pump of constant voltage frequency conversion water supply installation body intake end just can effectively be gone into lower floor to the upper strata in the water tank to the suction, and the water between the two gets into user's pipeline (inlet tube 55 upper end can effectively draw upper water).

In fig. 1 and 2, when the motor speed reducing mechanism M drives the sliding block 54 to rise to a position close to the top dead center, the magnet CT approaches the reed pipe GH, so that the internal contact of the reed pipe GH is closed, the 12V power supply positive electrode enters the relay K positive electrode power supply input end through the reed pipe GH with the closed internal contact, and the relay K is electrified to pull the control power supply input end and the normally closed contact end to be open; because, time switch A1's anodal power input end 1 foot and relay K normally closed contact branch are connected, so first set time switch A1 and motor reduction gears M can lose the electricity in succession and can no longer work this moment, have prevented that motor reduction gears M from driving sliding block 54 and go upward too much obstructed, cause this novel whole work unusual. When the motor speed reducing mechanism M drives the sliding block 54 to descend to a position close to the bottom dead center, the magnet CT can be close to the reed switch GH1, then, the internal contact of the reed switch GH1 is closed, the 12V power supply positive pole enters the positive power supply input end of the relay K1 through the reed switch GH1 with the closed internal contact, and the relay K1 is electrified to attract the control power supply input end and the normally closed contact end to be open; because, time switch A2's positive pole power input end 1 foot and relay K1 normally closed contact end are connected, so second time switch A2 and motor reduction mechanism M can lose the electricity in succession and can no longer work this moment, have prevented that motor reduction mechanism M from driving sliding block 54 and have descended too much obstructed, cause this novel whole work unusual. Through the combined action of all the mechanisms and the circuits, the two sets of time control switches can respectively output positive and negative and positive dipolar power supplies in a required time period, and the negative and positive dipolar power supplies enter the power input two ends of the motor reducing mechanism M, so the motor reducing mechanism M can drive the sliding block 54 to move up and down in the water tank through the screw rod 52, and further the sliding block 54 can drive the water inlet pipe 55 to move up and down in the water tank within a certain time period, the water inlet end of the booster pump of the constant-voltage variable-frequency water supply device body can be effectively pumped into the upper layer to the inner lower layer in the water tank, and water between the upper layer and the lower layer enters a user pipeline, the water in the upper layer and the lower layer in the water tank can be used within a short time period, the time that the water in the upper.

FIG. 2, relay K, K1 is a DC12V relay; the reed switches GH and GH1 are normally open contact type reed switches with a glass shell of a type MKA 14103.
