The specific embodiment
The invention provides a kind of motor-driven release, this motor-driven release comprises Electric Machine Control pipe nipple and the storehouse, source that is connected by ratchet 4 structure movements with the Electric Machine Control pipe nipple.Adopt split-type design between the motor part of this release and storehouse, source, the pawl type structure is adopted in the connection between two parts, and dismounting is quick.Referring to Fig. 6, pawl structures connects storehouse, source and motor part, and can quick-detachment, try one's best when guaranteeing execute-in-place few and radioactive source time of contact.
The Electric Machine Control pipe nipple comprises power supply, single-chip microcomputer and circuit for controlling motor; Power supply, single-chip microcomputer and circuit for controlling motor all are integrated on circuit board 1.Power supply and circuit for controlling motor access respectively single-chip microcomputer; Circuit for controlling motor drives the work of storehouse, source.The needed voltage of power unit design circuit, this circuit provides-voltage of 5V; Single chip circuit is mainly by gathering the umber of pulse of Hall element, and data acquisition bus voltage controls the level of GB and SF, thus the control motor; Circuit for controlling motor is to utilize the conducting of metal-oxide-semiconductor or cut-off control the release of motor and close.
Referring to Fig. 1, the function of power supply is to provide instrument work required-5V voltage, and the instrument operating voltage is turn-offed during greater than 95V when instrument bus voltage.When instrument bus voltage (BUS) surpass-during 50V, Q2, Q3 are in conducting state, late-class circuit Q1 is in off state, voltage-stabiliser tube D6 provides-5V voltage.
Referring to Fig. 2, the main data acquisition bus voltage of single chip circuit and Hall element output umber of pulse.Hall element is arranged on motor, and when electric machine rotation, Hall element produces pulse, sends into the single-chip microcomputer counting, thereby calculates the stroke of motor.Single chip circuit is controlled the level of pin SF and GB by data acquisition bus voltage and motor speed, and then controls motor.
Referring to Fig. 3, in circuit for controlling motor, Q4, Q5, Q6 and motor form the circuit that opens a position.Q7, Q8, Q9 and motor composition close the storehouse circuit.Whole equipment circuit operating principle is as follows:
When cable end voltage 0～-during 50V, GB, SF are 0V, Q4, Q5, Q6, Q7, Q8, Q9 all are in cut-off state, motor is not worked; When cable end voltage-50V～-60V between the time, GB=-5V, SF=0V, Q4, Q5, Q6 conducting, Q7, Q8, Q9 cut-off, the motor forward was controlled release and was opened a position this moment, stopped after completing until release opens a position; When cable end voltage be-60V～-75V between the time, GB=0V, SF=0V, Q4, Q5, Q6, Q7, Q8, Q9 cut-off motor are not worked.When cable end voltage-75V～-85V between the time, GB=0V, SF=-5V, Q7, Q8, Q9 conducting, Q4, Q5, Q6 cut-off, motor reversal was controlled release and was closed the storehouse this moment, completed rear motor and quit work until release closes the storehouse.
Referring to Fig. 4, the storehouse, source comprises that electric machine assembly, lead screw assembly 5 and storehouse, source open a position and closes the storehouse assembly; Electric machine assembly drives the storehouse, source by lead screw assembly 5 and opens a position and close storehouse assembly work; Electric machine assembly comprises power transmission shaft, be arranged on the Hall subassembly 2 on power transmission shaft and be arranged on magnet steel on Hall subassembly 2 movement locus; Single-chip microcomputer gathers the pulse signal that Hall subassembly 2 produces; Circuit for controlling motor is controlled machine operation.The Stroke Control of this release has been omitted travel switch, but is determined by the length of leading screw.Even leading screw move under motor-driven after the length ends disengage threads motor still rotational lead screw no longer move, after changing voltage cable and making motor reversal, threads of lead screw begins again interlock, oppositely shift motion begins until another end is thrown off again.The counting decision that stops being produced by Hall element pulse of motor is equipped with magnet steel on motor, when electric machine rotation, magnet steel acts on Hall element makes it produce pulse, sends into the single-chip microcomputer counting.Referring to Fig. 5, the Hall segment count mainly gathers the magnet steel of machine shaft drive to the count pulse of Hall generation.
This electric releaser adopts the negative pressure power supply mode to carry out the opening and closing operation of door, makes instrument open and close the storehouse operation and can carry out time-sharing with other pipe nipple module.When giving single-core cable in addition during negative pressure, instrument opens and closes the storehouse operation, when giving single-core cable in addition during malleation, completes the logging tasks of other pipe nipples.Opening a position and closing has wider safe transition band between the voltage of storehouse, guaranteed the reliability of door switch motion.When cable end voltage-50V～-the 60V scope in the time, door is opened, and discharges isotope; When cable end voltage-75V～-during 85V, door is closed, and stops discharging isotope.
The storehouse, source opens a position and closes the storehouse assembly and comprise upper piston 6, lower piston 7 and the trace that is used for connecting upper piston 6 and lower piston 7; Leading screw drives trace and carries out rectilinear motion.
Be provided with sealing ring on upper piston 6 and/or lower piston 7; Upper lower piston all is equipped with sealing ring, guarantees storehouse, source sealing, and under the elongate rod that is arranged on feed screw nut drove, when moving downward end of travel together, upper lower piston left sealing surface, and the radioactivity mixture is taken out of Yuan Cang by water, and release function is realized.Motor reversal, feed screw nut again drive lower piston by elongate rod after interlock and move upward together, and sealing is realized in the storehouse, source again.
In addition, owing to not adopting travel switch, but use the leading screw length restriction on Stroke Control, the length of this release is shorter than the release of other types, also no longer is subjected to the installing space restriction of travel switch and limited on external diameter.Pawl structures makes the storehouse, source partly separate with motor, and use together in motor part storehouse, several source of can arranging in pairs or groups, and reduces use cost.
