Abstract
The invention relates to a cam-type electric closing device based on an intelligent switch, which aims at solving the problem that the intelligent switch needs to be manually closed after being tripped and the secondary tripping of the intelligent switch is influenced. The cam-type electric closing device based on the intelligent switch consists of a fixed bracket, an intelligent switch, a guide rod, a cam and a motor. The intelligent switch is fixed at the upper end of the fixed bracket, a projection which is used for fixing an ejector rod is arranged in the middle of the fixed bracket, and a motor groove which is used for fixing the motor is arranged in the lower end of the fixed bracket; a connector which is connected with a movable rod of the intelligent switch is arranged at the upper end of the ejector rod; the ejector rod only can move in one direction, and a roller is arranged at the lower end of the ejector rod and used for rolling on the cam; the cam is designed into a form with a shearing part which is used for preventing the intelligent switch from being seized. When in closing, the motor drives the cam to rotate, the intelligent switch is pushed to be closed, and after the intelligent switch is closed, since a small time difference exists from the completion of the closing to the rotation stopping of the motor, the cam can cross a critical position, and the secondary tripping of the intelligent switch is not influenced.
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 is under defined terms, and the circuit breaker of energy automatic shutoff circuit when residual current meets or exceeds setting is used 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 finishing the function of automatic brake separating when electrical leakage quantity or overload quantity surpass preset value, 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 closing a floodgate with 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, then 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, the operation of realization electric switch-on such as the need manual operation, then needs rotary knob to manual position, make trundle break away from cotter way, driving handle is realized manual divide-shut brake again.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 transform, otherwise whole device damages easily, 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 can so that described drive plate only rotates along same direction, for example only rotate along clockwise direction by one-way clutch mechanism.During motor operation, its output shaft drives ratchet and rotates, the part spring body that is stuck on the 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 transform, 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
Based on the Cam-type electric telecontrol knife-blade switch device of 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.
