Description
Technical field
The invention belongs to the structural design field of the switching-on mechanism of intelligent switch, be specifically related to a kind of Cam-type electric telecontrol knife-blade switch device based on intelligent switch.
Background technology
Residual current circuit breaker, be under defined terms, and the circuit breaker of energy automatic shutoff circuit when residual current meets or exceeds setting, for preventing because of the accidents such as loss of life or personal injury, device damage and fire of getting an electric shock, electric leakage causes.
Traditional residual current circuit breaker is except when electrical leakage quantity or overload quantity surpass preset value, completing the function of automatic brake separating, and other times will be realized separating brake or close a floodgate all needing manual operation.
The trend of present electrical equipment is the future development towards intelligent and automation, and the technical staff has also developed several residual current circuit breaker that can automatically realize combined floodgate and separating brake at present.
Patent documentation CN202018933 discloses a kind of novel switching-on mechanism scheme: adopted eccentric rotating disk, motor rotarily drives the rotation of eccentric rotating disk, eccentric rotating disk is placed on the round platform of output shaft of cotter way, the drivening rod driving handle resets and closes a floodgate, realize the electric switch-on operation, as need manual operation, need rotary knob to manual position, make trundle break away from cotter way, then driving handle is realized manual divide-shut brake.Obviously, total reliability, feasibility are not high, need pushbutton unit, and reckon without in traditional motor-operating mechanism, after the motor stall, because installed the multi-stage gear reduction box additional, its output shaft generally all can't backwards rotation, cause connecting rod also can't move, so its output shaft has limited the operation of manual-operating mechanism.
Patent documentation 02284818.5 discloses a kind of Leakage Circuit Breaker Dual-Use Switch Rack Device, and employing ratchet and tooth bar engagement system have solved the problem of automatic and manual divide-shut brake, but also there is obvious deficiency in this scheme; Manually, automatic closing needs arrangement of clutch to be transformed, otherwise whole device easily damages, when manual switch, during to automatic closing, ratchet and tooth bar often can mesh the unsuccessful whole failure of apparatus that causes.
Patent documentation CN 101916693 and CN 201796838, by one-way clutch mechanism, can, so that described drive plate only rotates along same direction, for example only rotate along clockwise direction.During motor work, its output shaft drives ratchet and rotates, the part spring body be stuck on ratchet of described jump ring is propped up by the drive surface of clutch ratchet, thereby driving jump ring and drive plate rotates, and then by being arranged on the bearing pin drivening rod on drive plate one end, the final divide-shut brake handle that drives is realized the divide-shut brake action, after the motor stall, can pass through external spanner, inner hexagon spanner for example, pull securing member and drive the shifting part rotation, shifting part is directly pulled the bearing pin that connects connecting rod and drive rod, and then drivening rod rotates.But also there is obvious deficiency in this scheme; 1, manually, automatic closing needs Circlip apparatus to be transformed, 2, the location of Circlip apparatus increased volume and the complexity of whole transmission mechanism, causes the circuit breaker volume larger.
Summary of the invention
Cam-type electric telecontrol knife-blade switch device based on intelligent switch, its purpose must rely on closing by hand after being to solve intelligent switch tripping operation, problem that can not Long-distance Control, and do not affect the secondary trip of intelligent switch after closing a floodgate.
The first embodiment of the Cam-type electric telecontrol knife-blade switch device based on intelligent switch, by fixed mount, intelligent switch, push rod, disc cam, motor forms.Wherein the fixed mount upper end is used for fixedly intelligent switch, and there is projection centre, porose on projection, and two projections are for fixed mandril, and there is motor slot the lower end of fixed mount, for fixed electrical machinery; There is the joint be connected with the motion bar of intelligent switch the push rod upper end, joint need not accurately be processed, as long as can play the effect that prevents that push rod and intelligent switch break away from, hole on the centre of push rod and fixed mount projection matches, make push rod to move in one direction, there is roller the lower end of push rod, for rolling on disc cam; The profile of disc cam is designed to have at a place pattern of trimming, and for preventing that intelligent switch is by dieback, causing can not secondary trip, and there is the hole be connected with motor the centre of disc cam.
During use, push rod is in the hole of the projection of fixed mount, and an end is connected with intelligent switch, and an end is unsettled, and disc cam is connected on motor, and makes the position of disc cam in not hindering push rod to fall.
When the intelligent switch tripping operation, the intelligent switch motion bar is pushed into below by push rod, when needs close a floodgate, press motor driven switch, drive motors is rotated counterclockwise, the driven by motor cam is rotated counterclockwise, the roller of push rod rolls and makes push rod by jack-up along the disc cam face, the promotion intelligent switch closes a floodgate, and after closed action completes, because combined floodgate is accomplished to, stops electric machine rotation a small time difference is arranged, make cam turn over critical localisation, so, when the intelligent switch secondary trip, disc cam can not stop the whereabouts of push rod.
The second embodiment of the Cam-type electric telecontrol knife-blade switch device based on intelligent switch, by fixed mount, intelligent switch, push rod, cylindrical cam, motor forms.Wherein the fixed mount upper end is used for fixedly intelligent switch, and there is projection centre, porose on projection, and two projections are for fixed mandril, and there is motor slot the lower end of fixed mount, for fixed electrical machinery; There is the joint be connected with the motion bar of intelligent switch the push rod upper end, joint need not accurately be processed, as long as can play the effect that prevents that push rod and intelligent switch break away from, hole on the centre of push rod and fixed mount projection matches, make push rod to move in one direction, there is roller the lower end of push rod, for rolling on the cylindrical cam working face; The profile of cylindrical cam is designed at a place pattern of cut-off suddenly, and for preventing that intelligent switch is by dieback, causing can not secondary trip, and there is the hole be connected with motor the centre of cylindrical cam.
During use, push rod is in the hole of the projection of fixed mount, and an end is connected with intelligent switch, and an end is unsettled, and cylindrical cam is connected on motor, and makes the position of cylindrical cam in not hindering push rod to fall.
When the intelligent switch tripping operation, the intelligent switch motion bar is pushed into below by push rod, when needs close a floodgate, press motor driven switch, drive motors turns clockwise, the driven by motor cylindrical cam turns clockwise, the roller of push rod rolls and makes push rod by jack-up along the cylindrical cam working face, the promotion intelligent switch closes a floodgate, and after closed action completes, because combined floodgate is accomplished to, stops electric machine rotation a small time difference is arranged, make cylindrical cam turn over critical localisation, so, when the intelligent switch secondary trip, cylindrical cam can not stop the whereabouts of push rod.
It should be pointed out that in order to reduce costs, the present invention does not add any motor angle and controls feedback device, so after having closed a floodgate, can not continue for a long time drive motors, should make cam and push rod break away from, prevent from affecting the tripping operation of intelligent switch, guaranteed the reliability of mechanism, fail safe.
In summary, must rely on closing by hand after the invention solves intelligent switch tripping operation, problem that can not Long-distance Control, and do not affect the secondary trip of intelligent switch after closing a floodgate, guaranteed mechanism reliability.
