Detailed Description
In order to clearly illustrate the technical features of the present solution, the present solution is explained below by way of specific embodiments.
A novel energy storage device of a 220KV circuit breaker with three linkage spring mechanisms comprises a driving wheel 1, an energy storage gear 2 meshed with the driving wheel 1 and a tripping device arranged on the energy storage gear 2 and matched with the driving wheel 1.
The axis of action wheel 1 is parallel to each other with energy storage gear 2's axis, and action wheel 1 is used for driving energy storage gear 2 and rotates, and trip gear is used for breaking away from energy storage gear 2 the meshing of action wheel 1 to make action wheel 1 idle running and can't drive energy storage gear 2 and rotate, when having avoided energy storage gear 2 to store up full energy, the unable tooth phenomenon of beating that leads to that stops of action wheel in time has improved the reliability of energy storage.
The tripping device comprises a notch which is arranged on the energy storage gear 2 and is positioned at the position where the energy storage gear 2 is meshed with the driving wheel 1, a tripping gear 3 which is coupled in the notch and is meshed with the driving wheel 1, a reset torsion spring 4 which is fixedly arranged on a rotating shaft of the tripping gear 3 and drives the tripping gear 3 to elastically deform towards the outside of the notch, and a limiting mechanism which is fixedly connected in the notch and corresponds to the tripping gear 3. The notch extends from the tooth position of the energy storage gear 2 to the axis position, occupies the positions of a plurality of teeth on the energy storage gear 2, is provided with a plurality of teeth on the tripping gear 3, is used for supplementing missing teeth on the energy storage gear 2, and is simultaneously meshed with the driving wheel 1 through the energy storage gear 2 and the tripping gear 3, so that the energy storage gear 2 is driven to rotate through the driving wheel 1. The one end of dropout gear 3 sets up the pivot, and the axis of pivot is parallel with the axis of energy storage gear 2, and 4 covers of reset torsion spring are established in the pivot, and one end card is on energy storage gear 2, and the other end card is on dropout gear 3 for play dropout gear 3 outside the opening, stop gear sets up the other end at dropout gear 3, is used for prescribing a limit to the position of dropout gear 3, makes reset torsion spring 4 will prescribe a limit to the effect that dropout gear 3 bounced to be in same cambered surface with energy storage gear 2.
The limiting mechanism comprises a limiting pin 6 fixedly connected in the opening, and the energy storage gear 2 and the teeth of the tripping gear 3 are positioned in the same cambered surface through the limiting pin 6. The spacer pin 6 is a cylinder, and the one end that the pivot was kept away from to trip gear 3 is equipped with the lug, and the lug top is on the cylinder to it is spacing to form trip gear 3, is in same cambered surface through the tooth that makes energy storage gear 2 and trip gear 3, makes the tooth of energy storage gear 2 periphery keep intact, thereby makes the whole week of energy storage gear 2 periphery and action wheel 1 meshing, has guaranteed that action wheel 1 drives energy storage gear 2 pivoted stability.
The rotating shaft of the tripping gear 3 is positioned in the opposite direction of the rotating direction of the limiting pin 6. Energy storage gear 2 is clockwise rotation, consequently, drive spacer pin 6 clockwise rotation, and the pivot of dropout gear 3 is located the counter clockwise of spacer pin 6, when action wheel 1 drives energy storage gear 2 and rotates, action wheel 1 counter clockwise rotates, when action wheel 1 meshes with dropout gear 3, action wheel 1 gives energy storage gear 2 a power of stirring to the opening, if energy storage gear 2 drives the elasticity of closing spring is greater than reset torsion spring 4's elasticity this moment, action wheel 1 can overcome reset torsion spring 4's elasticity, press dropout gear 3 to the opening, dropout gear 3 uses the pivot to have a clockwise angular variation as the center this moment, thereby make the tooth of dropout gear 3 stagger with the tooth of action wheel 1, thereby the dead phenomenon of tooth or gear card has been avoided appearing.
The opening occupies four tooth positions of the energy storage gear 2, the tripping gear 3 is four tooth positions corresponding to the opening, two teeth are arranged at the position of the tripping gear 3 close to the rotating shaft, one tooth is arranged at the position of the tripping gear close to the limiting pin 6, and one tooth position is arranged between the two teeth and one tooth. By the aid of the position of the vacant teeth, when the energy storage gear 2 cannot rotate continuously, the teeth of the driving wheel 1 can be staggered with the teeth of the tripping gear 3, and meshing caused by too tight tooth space is avoided.
The axis of the driving wheel 1 is penetrated with a hinge shaft 5. The driving wheel 1 is driven to rotate by the hinge shaft which is connected with the output shaft of the motor through the hinge shaft 5, so that the energy storage device is driven.
The utility model discloses when initial condition, action wheel 1 and the meshing of dropout gear 3, regard as energy storage gear 2 to rotate a whole circle when action wheel 1 once more meshes with dropout gear 3, when energy storage gear 2 is rotatory for the integer circle, energy storage gear 2 energy storage is accomplished, when energy storage gear 2 drives closing spring energy storage and accomplishes promptly, dropout gear 3 just rotates the position with action wheel 1 meshing, and on the tooth that the position of dropout gear 3 and action wheel 1 meshing exists alone for dropout gear 3, thereby be convenient for dropout gear 3 in time to trip with action wheel 1, the reliability is higher.
The utility model discloses can be under the condition that the motor in time cut off the power supply, closing spring is under tripping gear 3's effect, action wheel 1 idle running, and closing spring no longer stores energy, makes circuit breaker mechanism energy storage, combined floodgate operation process smooth, reliably go on, has avoided the tooth phenomenon of beating between the gear, has slowed down the rate of wear of gear, has reduced mechanical failure's incidence, has prolonged energy memory's life.
