Abstract
The utility model relates to a timer for counting the running time of an electric motor. A voltage reducing, rectifying and voltage stabilizing circuit is used for providing DC power supply to a COMS integrated circuit with a quartz oscillator, the COMS integrated circuit sends out pulse signals to control a stepper motor, and the stepper motor drives a counter L for counting. The voltage reducing, rectifying and voltage stabilizing circuit is connected with the power supply terminal of the motor, and so long as the power supply of the motor is switched off, the timer can begin counting the time. The utility model can solve the metering problem caused by the reason that electric motors needing to be moved frequently in rural districts are not inconvenient to be provided with electric meters and can promote electricity users to save electricity.
Description
The utility model relates to a kind of timer that motor is counted working time.
At present, use the micromachine of movable types such as water pump draws water, Electric rice thresher more in the rural area, because of these motor work places often move and scope wide, poor working environment, thus be not suitable for installing active watt-hour meter, because of the vertical installation of watt-hour meter can not surpass to tilt 2, the aluminium dish of watt-hour meter is to rotate by magnetic strength stress, tolerance clearance is very little, when it is installed on the mobile device, and easy stuck aluminium dish or cause very big error.So a large amount of micromachines that often must move are not all installed measuring instrument in the rural area, can only estimate electric weight by the every mu of field number that draws water, beats rice, and disregard the working time length of motor, bring very big difficulty to charge, cause waste of electric energy.
The timer that provides a kind of motor working time that normal palpus is moved to count is provided the purpose of this utility model.
The utility model is finished with following mode: the motor running timer, after comprising that transformer B step-down exports rectifier Z rectification to, carry out filtering and stabilivolt CW voltage stabilizing through capacitor C, resistance R, tape splicing has the COMS integrated circuit (IC) of quartz (controlled) oscillator BW on the dc supply of stabilivolt CW two ends output, by COMS integrated circuit (IC) output pulse signal control step motor M, drive counter L by stepper motor M.Counter L drives digit wheel by reduction gearing to constitute.
The utlity model has simple in structure, energy consumption is little, cost is low, can be under various environment operate as normal.It is attempted by on the power end of motor, as long as the motor power that closes, it just picks up counting, can note the actual run time of motor, so just can be by converting the nominal power of separate unit motor and the working time of noting electric degree, it has solved in the rural area problem of the motor electricity consumption metering that those all kinds of normal need that are not easy to install watt-hour meter move.Can impel electric consumer's using electricity wisely and conveniently collect the electricity charge.
Fig. 1 is the utility model circuit theory diagrams
Fig. 2 is the structural representation of counter L
Below in conjunction with accompanying drawing the utility model is described in further detail:
As shown in Figure 1: the utility model is the supply terminals by the former edge joint motor D of transformer B, so as long as close a switch K, this timer just can chargedly carry out work.After transformer B step-down, output AC power source carries out rectification to rectifier Z, the output dc supply is after filtering of capacitor C resistance R and stabilivolt CW voltage stabilizing, dc supply is provided for the COMS integrated circuit (IC) that has quartz (controlled) oscillator BW, this moment COMS integrated circuit (IC) output pulse signal control step motor M, the COMS integrated circuit (IC) that has quartz (controlled) oscillator BW adopts model to be: 969A, pulse signal of its per second output, stepper motor M adopts 2 utmost point motors, so stepper motor M receives a pulse control signal p.s., it rotates 180 ° is half cycle, and rotate a week per 2 seconds, drives counter L with stepper motor M and carries out time counting, counter L drives digit wheel by reduction gearing to constitute, as shown in Figure 2, reduction gearing is driven by stepper motor M, and reduction gearing adopts level Four to slow down, 2 ratio of revolution is 1800:1 from gear 1 to gear, digit wheel by hour and minute two kinds of digit wheels represent that on the number of minutes character wheel a circumference is divided into 12 five equilibriums, every five equilibrium is represented 5 minutes; Hourage character wheel b is divided into 10 five equilibriums, and every five equilibrium is represented 1 hour.As move 5 minutes then the COMS integrated circuit (IC) send 300 pulses, stepper motor M changes 150 and changes, drive the number of minutes character wheel a through reduction gearing transmission deceleration and rotated for 1/12 week, drive with reduction gearing between the number of minutes character wheel a and the hourage character wheel b, its ratio of revolution is 10:1, be that the number of minutes character wheel circles, the hourage character wheel changeed for 1/10 week.It has simple in structure, intuitive display.
Claims (2)
1, a kind of motor running timer, after it comprises that transformer B step-down exports rectifier Z rectification to, carry out filtering and stabilivolt CW voltage stabilizing through capacitor C, resistance R, tape splicing has the COMS integrated circuit (IC) of quartz (controlled) oscillator BW on the dc supply that it is characterized in that exporting at stabilivolt CW two ends, by COMS integrated circuit (IC) output pulse signal control step motor M, drive counter L by stepper motor M.
2,, it is characterized in that counter L drives digit wheel by reduction gearing to constitute according to the described timer of claim 1.
