Description
Technical field
The utility model belongs to the breaker structure design field, is specifically related to a kind of hand-movement and motor-driven integrative intelligent breaker.
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 to prevent 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.For example Chinese patent 200620105204.2 disclosed a kind of residual current circuit breaker are equipped with arc-extinguish chamber, contact, leakage tripping device, overcurrent trip, the copper cash that is flexible coupling, current transformer, zero sequence current mutual inductor, go up leading-out terminal, operating mechanism, following leading-out terminal in its pedestal.This kind residual current circuit breaker can realize earth leakage protective and overload protection preferably, but its shortcoming is exactly will realize separating brake at ordinary times or close a floodgate all needing manual operation.
The trend of present electrical equipment is that the direction towards intelligent and automation develops, and the technical staff has also developed several residual current circuit breaker that can realize automatically closing a floodgate with separating brake at present.
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 tangible 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 cause whole failure of apparatus through regular meeting's engagement is unsuccessful.
The utility model content
The purpose of this utility model provides a kind of good reliability, not fragile, lower-cost hand-movement and motor-driven integrative intelligent breaker.
The technical scheme that realizes the utility model purpose is: a kind of hand-movement and motor-driven integrative intelligent breaker comprises base, middle cover and loam cake; Be provided with breaker body and the divide-shut brake handle that exposes middle cover in the described base; Cover in described and be provided with the electrodynamic type operating mechanism, cover on described and be provided with manual-operating mechanism; Described electrodynamic type operating mechanism comprises motor with output shaft, is subjected to output shaft to drive transmission mechanism and the one-way clutch mechanism that is used to drive the divide-shut brake handle; Described one-way clutch mechanism comprises that relative fixed is arranged on clutch ratchet on the output shaft, is provided with the drive plate in circular clutch hole and is used for driving the clutch part that drive plate rotates under the clutch ratchet effect; The edge of described eccentric ratchet evenly is provided with a plurality of clutch ratchets, and an end face of described each clutch ratchet is a drive surface, and the other end is the sliding surface of arc shaped, and described eccentric ratchet is arranged in the circular clutch hole of drive plate; The two sides of described drive plate respectively are provided with a spacing hole that is communicated with described clutch hole, described spacing hole direction is set perpendicular to described clutch hole; Described clutch part is the jump ring that is provided with breach, and the spring body at described breach two ends inserts in the spacing hole of described drive plate, and is stuck on the clutch ratchet of the relative two side ends of clutch ratchet; Described transmission mechanism comprises the connecting rod that an end links to each other with the divide-shut brake handle, and the other end of described connecting rod is rotationally connected by an end of bearing pin and drive plate; Described manual-operating mechanism comprises and is arranged on the rotating shaft that covers, is arranged on being used on the rotating shaft medial extremity and drives the shifting part that bearing pin rotates and be arranged on securing member on the rotating shaft outboard end; During described motor forward rotation, its output shaft drives the clutch ratchet, and then the drive surface by the clutch ratchet promotes jump ring and rotates around output shaft, and described jump ring drives drive plate and rotates around output shaft, and described drive plate drives the action of divide-shut brake handle by transmission mechanism; After the described motor stall, securing member drives shifting part by rotating shaft under external force and rotates, described shifting part is stirred bearing pin and is rotated around motor output shaft, synchronous drivening rod of described bearing pin and drive plate, drive plate drive jump ring slips over the clutch ratchet along the sliding surface of clutch ratchet, and described connecting rod drives the action of divide-shut brake handle.
In the such scheme, a side end face of described drive plate is provided with location notch, and the part spring body of described jump ring is arranged in described location notch.
In the such scheme, described jump ring is the rectangle jump ring, and described breach is positioned at rectangle jump ring center on one side.
In the such scheme, the top of described divide-shut brake handle is provided with fastening bolt, and an end of described connecting rod is provided with mounting hole, and described metal bolts is positioned at this mounting hole.
The utlity model has positive effect: in (1) the utility model,, can for example only rotate along clockwise direction so that described drive plate only rotates along same direction owing to be provided with one-way clutch mechanism.During motor work, 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, finally drive the divide-shut brake handle and realize the divide-shut brake action by being arranged on the bearing pin drivening rod on drive plate one end.In traditional motor-operating mechanism, after the motor stall,, cause connecting rod also can't move, so its output shaft has limited the operation of manual-operating mechanism because its output shaft generally all can't backwards rotation; The utility model then passes through one-way clutch mechanism, fine this drawback that solved.In the utility model, after the motor stall, can pass through external spanner, for example inner hexagon spanner is pulled securing member and is driven the shifting part rotation, and shifting part is directly pulled the bearing pin that connects connecting rod and drive rod, and then drivening rod rotates; If there is not one-way clutch mechanism, be impossible stir connecting rod at this moment, because braked by the output shaft of motor with shifting part.Owing to the utlity model has one-way clutch mechanism, described bearing pin is when output shaft rotates, driving drive plate and jump ring rotates, this moment, described jump ring rotated along the sliding surface of ratchet, when rotating, the breach of jump ring increases, until slipping over this sliding surface, after jump ring slips over this sliding surface, owing to no longer strutted by sliding surface, described jump ring is under self elastic reaction, and its breach recovers life size again, again be stuck in the ratchet two side ends, owing to need not ratchet with commentaries on classics,, realize manual operation smoothly so can not be subjected to the restriction of motor output shaft, and need not to disclose a kind of Leakage Circuit Breaker Dual-Use Switch Rack Device, also independent torch manual converting mechanism will be set separately as patent documentation 02284818.5.In sum, the utlity model has good reliability, not fragile, lower-cost advantage.
