Abstract
The utility model provides a ratchet style energy-storing device, which is designed to solve the shortcomings of high processing precision, big processing difficulty, producing cost-increasing during the producing and employing process of a current clutch-style energy-storing device, and the current energy-storing device can not separate brakes and work under the composite condition of a circuit breaker, which burns an energy-storing motor, and accidents happen. The utility model comprises an energy-storing shaft (1), an energy-storing shaft case (2) is sleeved on the energy-storing shaft (1) and a convex wheel (5) is fixed on the energy-storing shaft (1), a groove is arranged on the energy-storing shaft case (2), a ratchet (4) is installed in the groove, a sheeting spring (6) is fixed on the energy-saving shaft case (2) by a screw nail (7), the convex wheel (5) which is fixed on the energy-storing shaft (1) is provided with an access slit.
Description
Affiliated technical field
The utility model discloses a kind of pawl type energy storage device, the closing operation in the time of can be with the energy storage of 2N65 type circuit breaker, and realize that according to fashionable the powerful device that closes a floodgate is relevant at circuit breaker.
Background technology
In power industry power supply, outage is common occurrence, and energy storage device is the critical component that is used to power, start when cutting off the power supply the circuit breaker operation.At present, being used for the 3AH type energy storage device that the 2N65 type drives the circuit breaker operation is the disengaging type energy storage device that is made of five rollers and last five planes of energy storage axle.This disengaging type energy storage device has following defective in producing and using: require the machining accuracy height man-hour adding, so difficulty of processing big, increase production cost; Clutch action by five rollers during the operation of this disengaging type energy storage device drives the energy storage of energy storage axle, and in use if circuit breaker is according to closing, circuit breaker can't sub-switching operation, makes energy storage motor burn, have an accident.
Summary of the invention
The utility model is to exist in producing and using at existing disengaging type energy storage device to add machining accuracy height in man-hour, big, the increase production cost of difficulty of processing; In use circuit breaker can't sub-switching operation according to closing under the situation, burn energy storage motor, defective such as have an accident, the utility model provides a kind of pawl type energy storage device, this pawl type energy storage device is simple in structure, easy to operate, the circuit breaker that this pawl type energy storage device is used for power system power supply, can effectively solve circuit breaker according to fashionable combined floodgate work, realize powerful the combined floodgate, the accident of stopping takes place.
Taked following scheme for realizing target of the present utility model:
Make a kind of pawl type energy storage device, this pawl type energy storage device comprises the energy storage axle, is with the energy storage axle sleeve and is fixed with cam on the energy storage axle; The energy storage axle sleeve is provided with groove, and ratchet is installed in groove, is fixed with the compressing tablet spring on the energy storage axle sleeve; The cam of fixing storage on the energy axle has gap.
Remarkable advantage of the present utility model be simple in structure, easy to manufacture, use easy to maintenance.
Utilize the utility model control circuit breaker, circuit breaker is reliable, the accident of stopping takes place.
Description of drawings
Further describe technical characterictic of the present utility model below in conjunction with accompanying drawing:
Fig. 1, the utility model are preferentially selected the sectional structure schematic diagram of an embodiment for use;
The A-A sectional structure schematic diagram of Fig. 2, embodiment Fig. 1.
Among the figure, 1, energy storage axle 2, energy storage axle sleeve 3, pivot pin 4, ratchet 5, cam 6, compressing tablet spring 7, screw 8, strong
Specific embodiments
As shown in Figure 1 and Figure 2,1 among the figure is the energy storage axle, is set with energy storage axle sleeve 2 on the energy storage axle, has groove on energy storage axle sleeve 2, and ratchet 4 is installed in groove, and ratchet 4 is fixed together by pivot pin 3 and energy storage axle sleeve 2; Screw 7 is fixed together an end and the energy storage axle sleeve 2 of compressing tablet spring 6, and the other end of compressing tablet spring 6 is pressed in the place ahead of cam 5; The front end of ratchet 4 withstands on the opening position of cam 5.Cam 5 is inlaid between energy storage axle 1 and the energy storage axle sleeve 2, and cam 5 is tightened together by key 8 and energy storage axle 1, but can relatively rotate for energy storage axle sleeve 2.Compressing tablet spring 6 is pressed in the front end of ratchet 4 all the time, makes ratchet 4 reliably workings.
Operation principle of the present utility model is as follows:
When energy storage axle sleeve 2 rotates, drive the ratchet 4 that is fixed on the energy storage axle sleeve 2 and rotate together, when ratchet 4 turns to the opening position of cam 5, ratchet 4 drives cam 5 again and rotates, because cam 5 is fixed together with energy storage axle 1, therefore drive energy storage axle 1 by force and rotate, realize the purpose of energy storage.
