Description
The utility model relates to the escapement speed regulator in a kind of timer.
Use escapement hairspring escapement speed regulator with timer under the existing oil well more.It as the energy, transmits torque to escapement by train with flexible members such as clockwork spring or springs, by escapement to escapement hairspring vibrational system makeup energy.In this simultaneously, the periodic wobble of escapement is converted to the rotation of train or recording mechanism again by escapement.The clockwork spring moment of this mechanical timer is except being used to drive recording mechanism rotates, and must consume in the swing of the rotation of train and escapement.100 hours mechanical timer of a kind of work, be used for the former the not enough clockwork spring moment of output torque 40%, the latter then surpasses 60%.If continue to prolong the working time of timer, will give to manufacture and design and bring very big difficulty.
Secondly, the degree of stability in the cycle (or frequency) of escapement hairspring vibrational system is low, and the time error of walking of timer reaches about 1%.Moreover the tautochronism of escapement hairspring vibrational system is poor, and along with clockwork spring moment descends, the recording mechanism loading moment changes, the influence of factors such as train transmission quality change, the fluctuation that brings away time error.
Quartz electronic clock and watch had appearred in recent years, it is as the energy with battery,, to rotation, drive train, pointer or recording mechanism simultaneously and rotate as timing signal with the oscillation frequency of quartz (controlled) oscillator through the processing generation time pulsed drive stepping motor rotor folk prescription of electronic circuits such as frequency divider.The advantage of this clock is the timekeeping performance height, and relative error is less than 0.001%.But,, be difficult to drive recording mechanism and rotate then because the stepper motor output torque is little if it is applied to the down-hole timer.Though by increasing the motor output torque, approach such as increasing battery capacity can overcome above-mentioned deficiency, can cause overall dimensions to expand, structure does not allow.So quartz clock is not applied in the timer of device for subsurface measuring as yet.
The purpose of this utility model is to create a kind of novel speed regulator---electricity quartz speed regulator.Utilize the timer of this speed regulator design to drive the recording mechanism rotation with clockwork spring, as the timing signal source, the motor swing is swung in the conversion rear drive with quartz (controlled) oscillator, and swing-rotor is added with mechanical force moment M by escapement control
LThe escape wheel one-directional rotation, thereby reach control train clockwork spring and the accurate velocity of rotation of output shaft.This crystal chronometer is big except the output torque that promptly has mechanical timer, have again outside the high advantage of the timekeeping performance of quartz clock, also having can long-play (greater than 380 hours), reliable operation, it is little to stop the clock rate, the thin remarkable advantages such as (φ 20mm) of timer external diameter.Thereby make the measuring accuracy raising of the device for subsurface measuring match with this timer, functional reliability increases, and the one-shot measurement time lengthening satisfies the needs of well measurement.
Electricity quartz speed regulator with CMOS integrated circuit (CMOS IC), is swung motor by quartz resonator, clock, escapement, and compositions such as battery are seen Fig. 1 frame of broken lines.Then form crystal chronometer after being furnished with train and clockwork spring.
