Abstract
Disclosed is a crank-type dual-purpose closing device for a residual current circuit breaker. An eccentric wheel (2), an eccentric shaft (5) and a connecting rod (8) connected with a handle (9) are mounted on an output shaft of a decelerated motor (1), a crank arm (3), a spring (4), a toggling block (6) and an inner nut (7) are sequentially mounted on the eccentric shaft (5) from bottom to top, two ends of the connecting rod (8) are respectively connected with the crank arm (3) and the handle (9), an external projection portion of the toggling block (6) is laterally attached to the crank arm and a connecting shaft (10) of the connecting rod, and the spring (4) is sleeved on the eccentric shaft (5) while one end of the spring is tightly clamped on the connecting shaft (10). The utility model relates to an electric switch, which is an electrical and manual resetting and closing device used with the residual current circuit breaker. Further, the device has the advantages of electrically resetting and closing in case of normal operation of an electric network, and manually resetting and closing in case of electric network power failure and device failure, and is flexible and convenient in manual resetting and closing.
Description
Technical field
The utility model relates to the electric switch in a kind of low voltage electric network distribution system, with the supporting application of residual current circuit breaker, and can electric switch-on, the device that can manually close a floodgate again.
Background technology
CN90218794 discloses Mr.'s Guo Hanggan " electric operation device for auto-switch " patented technology; CN00251872 discloses " electric switch-on device " patented technology of Mr. Li Qianliang.Its mechanical common principle is crank or the eccentric wheel on the motor output shaft, through the reciprocating motion of connecting rod, handle is seesawed, and reaches electronic and resets and the effect of closing a floodgate.But the common weak point of these two patented technologies is: after the residual current circuit breaker tripping operation, chance encounter grid power blackout or electric switch-on device fault just can't realize resetting and close a floodgate, and are matters of regret in the practical application.
CN2577435 has announced a kind of " the dual-purpose closing device of residual current circuit breaker link-type ", setting-up eccentricity wheel on motor output shaft, the connecting rod two ends connect eccentric wheel and handle respectively, eccentric wheel and clutch fuse, the clutch of this device is made up of star-wheel, ratchet dish, sour jujube pin, driving lever, structure is complicated, and hand is stirred and owed nimble.
Summary of the invention
Above-mentioned deficiency at prior art, the purpose of this utility model is to design a kind of residual current circuit breaker tripping operation back energy electric switch-on under normal condition, under unusual (grid power blackout or electric switch-on device fault) situation, can manually close a floodgate simple in structure, the manual flexible dual-purpose closing device of residual current circuit breaker crank arm type.
The purpose of this utility model can realize by following measure: the dual-purpose closing device of this residual current circuit breaker crank arm type, on the motor output shaft after slowing down eccentric wheel and eccentric shaft are installed, the connecting rod that links to each other with handle in addition, eccentric shaft from bottom to top is equipped with successively and cranks arm, spring, shifting block and inner nut, the connecting rod two ends link to each other with handle with cranking arm respectively, the male part side of shifting block is pasted the connecting axle of cranking arm with connecting rod, and spring housing is on eccentric shaft, and an end tightly is stuck on the connecting axle.
Said inner nut is a hexagonal socket nut.
The beneficial effects of the utility model are after the residual current circuit breaker tripping operation, both can electronicly reset and combined floodgate, but hand-reset and combined floodgate again, the drawback that has overcome that single electric switch-on device has a power failure or can't reset and close a floodgate during plant failure after tripping operation, hand-reset of this device and combined floodgate simple in structure, easy to operate.
Description of drawings
Fig. 1 is installation site of the present utility model and structural representation (solid).
Fig. 2 is a vertical view of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with embodiment: the basic structure of residual current circuit breaker and the circuit structure of electric operation mechanism thereof, electric control circuit, all open in many relevant patents, it is prior art, no longer narration, crucial technical contribution are the mechanical structure parts of closing a floodgate and handling.On motor 1 projecting shaft eccentric wheel 2 is installed, eccentric shaft 5 is arranged on the eccentric wheel, this axle 5 from bottom to top is equipped with successively and cranks arm 3, spring 4, shifting block 6 and inner nut 7, crank arm and be connected with handle 9 through connecting rod 8, the male part of shifting block 6 can side be pasted the connecting axle 10 of cranking arm with connecting rod, inner nut 7 is a hexagonal socket nut, on the casing upper cover face directly over this nut the inner hexagon spanner through hole is arranged, spring 4 is the spiral jump ring, be enclosed within on the eccentric shaft 5, one end tightly be stuck in crank arm and the connecting axle 10 of connecting rod on, with wrench operated the time, make shifting block 6 and connecting axle 10 can only drive eccentric wheel 2 and clockwise rotate, can not rotate counterclockwise.
The utility model use is: under normal circumstances, after residual current circuit breaker tripping operation, electric control circuit instruction motor 1 rotates, the eccentric wheel 2 through linking to each other, crank arm 3 and connecting rod 8 driving handles 9 reset and close a floodgate, realize electric switch-on.If circuit breaker trip, grid power blackout or electric switch-on device fault by chance, then need inner hexagon spanner is inserted the spanner through hole to hexagonal socket nut 7, pull spanner, the connecting axle 10 that makes shifting block 6 works stir cranking arm of eccentric wheel 2 and top thereof and connecting rod when clockwise rotating also clockwise rotates, thereby affect handle to reset and combined floodgate, realize hand-reset and combined floodgate.
Claims (2)
1. dual-purpose closing device of residual current circuit breaker crank arm type, on motor (1) output shaft after slowing down eccentric wheel (2) and eccentric shaft (5) are installed, the connecting rod (8) that links to each other with handle (9) in addition, it is characterized in that eccentric shaft (5) from bottom to top is equipped with crank arm (3), spring (4), shifting block (6) and inner nut (7) successively, connecting rod (8) two ends link to each other with handle (9) with crank arm (3) respectively, the male part side of shifting block (6) is pasted the connecting axle (10) of cranking arm with connecting rod, spring (4) is enclosed within on the eccentric shaft (5), and an end tightly is stuck on the connecting axle (10).
2. the dual-purpose closing device of residual current circuit breaker crank arm type as claimed in claim 1 is characterized in that said inner nut (7) is a hexagonal socket nut.
