Description
Technical field
The present invention relates to a kind of burst rod driving mechanism of nuclear reaction pulsed reactor.
Background technology
Uranium hydrogen zirconium pulsed reactor in nuclear reactor can realize prompt supercriticality and the high Advanced Research Reactor of security performance, it is mainly using hydrogen as moderator, when power raises, temperature will improve, the slowing down declines of hydrogen, reactivity reduces immediately, and reactor has very large prompt negative temperature coefficient, thus in pulsing operation.
By the insertion of burst rod or exit the Neutron flux distribution changed in pulsed reactor during pulsed reactor reaction, thus start and stop pulsed reactor reaction or change the reaction power of pulsed reactor.Therefore burst rod drive unit is the key equipment of pulsed reactor.At present burst rod driving mechanism mainly with blow cylinder as driving element, mainly there is following problem: (1) emission rate is low, the peak power improving heap cannot be continued; (2) impact, vibrate comparatively greatly in mechanism end, and easily damage parts, failure rate is high; (3) discontinuous, the out of true of the speeds control of paired pulses rod in emission process, repeatability is not good.
Summary of the invention
The object of this invention is to provide a kind of burst rod driving mechanism, this kind of driving mechanism can improve emission rate, and its run end impact, vibrate little, can realize paired pulses rod speed continuous, accurately control.
The present invention solves the technical scheme that its technical matters takes: a kind of burst rod driving mechanism, and comprise the connecting link connecting burst rod, connecting link is connected with actuating unit, it is characterized in that:
The composition of described actuating unit is: the mover of linear electric motors is fixed on the slide unit of setting, and slide unit is connected with the side plate of frame by guideway, and the stator of linear electric motors is fixed on side plate; The front and rear panels of frame are separately installed with anterior bumper, posterior bumper, impact block installed by slide unit, anterior bumper aims at the front portion of impact block, and posterior bumper aims at the rear portion of slide unit.
The course of work of the present invention and principle: linear electric motors (mover) are by setting speed and stroke motion, thus drive slide unit to travel forward along guideway, the burst rod be connected with slide unit also travels forward thereupon, burst rod is made to insert pulsed reactor by setting speed, when arriving stroke end, impact block contact anterior bumper on slide unit, makes slide unit and burst rod firmly be parked on assigned address by the fixed time, completes the transmitting of burst rod; Subsequently by linear electric motors reverse drive, slide unit and burst rod move backward, and burst rod exits reactor, and the rear portion of last slide unit contacts with posterior bumper, and slide unit and burst rod are firmly parked in reference position.Circulate reciprocating impulse motion according to this that namely complete burst rod, realizes the control of paired pulses heap reaction.
Compared with prior art, the invention has the beneficial effects as follows:
One, adopt linear electric motors as driving power source, can more continuously, the travelling speed of accurately gating pulse rod, and the speed that burst rod is launched is high, and wide ranges (can reach 0 ~ 10m/s), improves the peak power of heap.
Two, impact damper is equipped with in the front end and end that drive stroke, the power output of linear electric motors and the cushion effect acting in conjunction of forward and backward impact damper are in slide unit, the impact that whole burst rod driving mechanism is subject to, vibrate little, both the degree of depth having made burst rod intercalation reaction pile is accurate, position is fixed, the travelling speed of burst rod continuously, accurately controlled, be not easy again damage parts, the reliability of mechanism is high; The servo drive system of linear electric motors can realize linear electric motors, improves the repeatability of experiment.
Further, the base plate of frame of the present invention is also provided with driving mechanism at a slow speed, the composition of driving mechanism is at a slow speed: servomotor is fixed on the base plate of frame by servomotor bearing, the output shaft of servomotor connects longitudinal leading screw, the screw supporting with leading screw is fixing on a mobile station by nut seat, passes through guideway at a slow speed and be connected with the guide rail bearing on base plate bottom transfer table; The cylinder bar of two bar cylinders of transfer table top cross is connected with shift fork by contiguous block, and shift fork is coupled with the sidepiece of impact block.
Like this, can when system warm-up, aimed at the sidepiece of impact block the shift fork of driving mechanism at a slow speed, the cylinder bar of two bar cylinder stretches out, and shift fork is coupled with impact block.Subsequently, servomotor drives slide unit and burst rod to-and-fro movement by screw mandrel, screw, transfer table, cylinder, shift fork, impact block successively, to verify Linear Motor Drive Mechanism, running-in, guarantee the validity and reliability of Linear Motor Drive Mechanism, improve the accuracy and reliability of whole system further.After preheating, the cylinder bar of parallel bars cylinder is retracted, and driving mechanism is thrown off with slide unit and is coupled at a slow speed, and system enters normal operating conditions, carries out reciprocating impulse motion by Linear Motor Drive Mechanism driving slide unit and burst rod.
Secondly, when linear electric motors lost efficacy, burst rod can be exited pulsed reactor, the safety and reliability of raising pulsed reactor by driving mechanism at a slow speed.
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
