Embodiment
As shown in the figure, a kind of infrared measurement of temperature knife switch lock, comprises housing 6, lock shaft 10, and lock shaft 10 is pull in the lock shaft hole set by housing 6, lock shaft 10 has predeterminated position point 7, and the sidewall in lock shaft hole is provided with the displacement transducer 13 of this predeterminated position point 7 change in displacement of induction, described lock shaft 10 is provided with pin-and-hole, and the position corresponding with this pin-and-hole arranges elastic central spindle, computer key is judged the ejection of control elastic central spindle by derived signals and is retracted, described housing arranges infrared measurement of temperature display, the back of described lock shaft 10 is provided with a groove, alignment pin 17 set by housing 6 and this fit depressions, institute's displacement sensors is by judging that the displacement of predeterminated position point 7 detects the pull position of lock shaft 10, described lock shaft 10 is provided with 2 pin-and-holes, described electromagnet 11 is also provided with 1 transducer 12, for ejection or the position that retracts of detecting core shaft, described housing 6 is fixed on the clamping plate of disconnecting link 4 by connecting bolt 9, described lock shaft 10 inserts disconnecting link 4 through installing clamping plate, to control point closing operation of disconnecting link 4, described computer key inserts locking device by connector 15.Infrared measurement of temperature display is convenient to floor manager and is observed temperature at any time, and in order to protect the safety of sensor electronic component, when temperature exceedes set point, infrared measurement of temperature display gives the alarm.
Disconnecting link is installed on mounting panel 5, knife switch lock 1 is installed on clamping plate A2 by connecting bolt 9, and disconnecting link 4 is also clamped by another clamping plate B3, and the back of described lock shaft is provided with a groove, alignment pin 17 set by housing 6 and this fit depressions, groove is for limiting the pull stroke of lock shaft.
What this equipment was mainly used in switch cubicle stops power transmission, both as Fig. 3, when disconnecting link 4 shifts top onto, equipment is power transmission state, when disconnecting link 4 is left behind as Fig. 4 position, equipment is power down mode, if equipment live is operated a switch can cause device damage, and client's accident power-off, cause economic loss, this locking device for control disconnecting link 4 deciliter, this locking device adopts computer key to control, by computer key according to upper one the state of lockset and equipment, pass through Logic judgment, satisfy condition and can open locking, operation disconnecting link 4, again lock disconnecting link, treat the unlatching that again satisfies condition.
Knife switch lock 1 to be installed with 9 clamping plate A2 by the connecting bolt of front end and is fixed, push and pull out control appliance disconnecting link by lock shaft 10, there is a groove at the back of lock shaft 10, by alignment pin 17 and groove fit, realize the horizontal pull of lock shaft, there is displacement transducer 13 side of lock shaft 10, lock shaft 10 there is a predeterminated position point 7, by the displacement variation value of predeterminated position point 7, detect lock shaft 10 position, when lock shaft 10 pull is to certain position, the mandrel of electromagnet 11 can eject, by locked for lock shaft 10, make lock shaft 10 cannot pull, to reach interlock, detection signal in locking can import computer key into by connector 15, computer key is sent to electromagnet according to Logic judgment output signal by connector 15, to control ejection or the withdrawal of electromagnet mandrel, the transducer 12 of electromagnet 11 rear end is for detecting the state of electromagnet mandrel.
When equipment needs power transmission, disconnecting link 4 has been latched in open position as Fig. 4 and Fig. 5, now computer key inserts locking device by connector 15, first computer key detects lockset state by Hall element, and equipment state, detecting electromagnet mandrel by transducer 12 is ejecting or retracting position, if at ejected position, then judges that lockset is at blocking; Then by displacement transducer 13 judgment device state, judge shift value, now lock shaft 10 is at half-travel position, with this judgment device at open position, meets power transmission condition.Computer key can give electromagnet signal transmission, electromagnet mandrel retracts, now operating personnel operate handwheel 14 and extract lock shaft 10 out, disconnecting link are shifted onto power transmission position, are pushed by lock shaft 10, change according to shift value, computer key judges that locking puts in place, to electromagnet signal transmission, ejects mandrel, locked lock shaft 10, completes transmission process.
This lockset also comprises end casing 8 and side cover plate 16, in order to protect internal component.
It may be noted that; above-mentioned execution mode is only the utility model preferred embodiment; for those skilled in the art, under the prerequisite meeting utility model works principle, any equivalent or similar replacement all falls into protection range of the present utility model.
