[0037] Example:

[0038] A circuit breaker opening and closing energy storage structure includes an operating handle latch shaft 7 and a circuit breaker rod 15.

The operating handle transmission gear 6 is meshedly connected to a ball bearing transmission gear 10 and a rack 23.

[0040] The circuit breaker opening and closing control intermittent gear 16 includes a shaft hole 1601, a gear side 1602 and an intermittent side 1603, and the arc lengths of the gear side 1602 and the intermittent side 1603 are equal;

[0041] The bidirectional torsion spring energy storage gear 21 includes a slide groove 2101, a second ball bearing 2102, an upper torsion spring fixing hole 2103 and a fourth shaft hole 2104;

[0042] The ball bearing positioning gear 20 includes a second positioning pin 2001, a ball bearing 1 2002 and a third shaft hole 2003. The second positioning pin 2001 can slide in the slide groove 2101.

[0043] The bidirectional torsion spring 19 is provided with an upper torsion spring joint 1901 and a lower torsion spring joint 1902;

[0047] The working principle of this utility model:

[0048] Perform closing operation:

[0049] When power transmission operation is required, the operator inserts the operating handle into the operating handle latch shaft 7 and rotates it counterclockwise, and the operating handle latch shaft 7 drives the operating handle transmission gear 6 fixed thereon to rotate counterclockwise.

[0050] The operating handle transmission gear 6 rotates counterclockwise to drive the ball bearing transmission gear 10 to rotate clockwise, and at the same time drives the rack 23 to move downward.

[0051] The ball bearing transmission gear 10 drives the transmission gear 1 13 by rotating clockwise, and the transmission gear 1 13 drives the transmission gear 2 14 to rotate clockwise.

[0052] Clockwise rotation of transmission gear 2 (14) causes rotation of its fixed shaft, which in turn drives the circuit breaker tripping and closing control intermittent gear (16). Simultaneously, the clockwise rotation of transmission gear 2 (14) causes counterclockwise rotation of ball bearing positioning gear (20). When operating handle transmission gear (6) rotates 180°, circuit breaker tripping and closing control intermittent gear (16) enters its travel range, driving counterclockwise rotation of bidirectional torsion spring energy storage gear (21). This causes bidirectional torsion spring (19) attached to it to store energy, while simultaneously driving clockwise rotation of circuit breaker tripping and closing indicator gear (17).

[0053] When the circuit breaker rod locking mechanism trigger shaft 25 reaches the top rod 2203 , it will slide inward due to its structural characteristics and will not trigger the circuit breaker rod locking mechanism 22 .

[0054] When the operating handle transmission gear 6 rotates 265°, the bidirectional torsion spring energy storage gear 21 drives the bidirectional torsion spring 19 mounted thereon to complete energy storage. Simultaneously, the rack 23 contacts the push rod 2203, causing it to shift. This displacement of the push rod 2203 actuates the rocker 2204. Simultaneously, the rocker 2204 shifts the push rod 2205 in the opposite direction, unlocking the circuit breaker lever fixing wheel 18.

[0055] Because the breaker rod locking mechanism 22 unlocks the breaker rod fixing wheel 18, the bidirectional torsion spring 19 releases its stored energy, causing the breaker rod fixing wheel 18 to rotate counterclockwise. This in turn causes the breaker rod 15, which is fixed to the breaker rod fixing wheel 18, to close and reach the closed position.

[0056] When the operating handle transmission gear 6 rotates 270°, the rack 23 reaches its lowest point, and the push rod 2203 on the circuit breaker lever locking mechanism 22 simultaneously moves. This displacement of push rod 2203 actuates the rocker 2204. Simultaneously, rocker 2204 shifts the positioning rod 2205 in the opposite direction. This locks the circuit breaker lever fixing wheel 18, and the circuit breaker opening / closing indicator gear 17 displays "closed," completing the closing operation.

[0057] To perform the opening operation:

[0058] When the equipment is in power-on state and needs to be repaired, the operator inserts the operating handle into the operating handle latch shaft 7 and rotates it clockwise, and the operating handle latch shaft 7 drives the operating handle transmission gear 6 fixed thereon to rotate clockwise.

[0059] The operating handle transmission gear 6 rotates clockwise to drive the ball bearing transmission gear 10 to rotate counterclockwise, and at the same time drives the rack 23 to move upward.

[0060] The ball bearing transmission gear 10 rotates counterclockwise to drive the transmission gear 1 13 to rotate clockwise. The transmission gear 1 13 drives the transmission gear 2 14 to rotate counterclockwise.

[0061] The transmission gear 2 14 rotates counterclockwise to rotate its fixed shaft, and the rotation of the shaft drives the circuit breaker opening and closing control intermittent gear 16. At the same time, the counterclockwise rotation of the transmission gear 2 14 drives the ball bearing positioning gear 20 to rotate clockwise.

[0062] When the operating handle transmission gear 6 starts to rotate, the circuit breaker opening and closing control intermittent gear 16 is in the stroke, driving the bidirectional torsion spring energy storage gear 21 to rotate clockwise. At this time, the bidirectional torsion spring energy storage gear 21 drives the bidirectional torsion spring 19 fixed thereon to store energy. At the same time, the bidirectional torsion spring energy storage gear 21 drives the circuit breaker opening and closing indicator gear 17 to rotate counterclockwise.

[0063] When the operating handle transmission gear 6 rotates 85°, the bidirectional torsion spring energy storage gear 21 drives the bidirectional torsion spring 19 mounted thereon to complete energy storage. Simultaneously, the rack 23 moves upward, driving the circuit breaker lever locking mechanism trigger shaft 25 to contact the push rod 2203 on the circuit breaker lever locking mechanism 22. This displacement of the push rod 2203 actuates the rocker 2204. Simultaneously, the rocker 2204 shifts the positioning rod 2205 in the opposite direction, thereby unlocking the circuit breaker lever fixing wheel 18.

[0064] Because the breaker rod locking mechanism 22 unlocks the breaker rod fixing wheel 18, the bidirectional torsion spring 19 releases its stored energy, causing the breaker rod fixing wheel 18 to rotate clockwise. This in turn causes the breaker rod 15, which is fixed to the breaker rod fixing wheel 18, to open and reach the open position.

[0065] When the operating handle transmission gear 6 rotates 90°, the push rod 2203 on the circuit breaker rod locking mechanism 22 simultaneously moves. This displacement of push rod 2203 actuates rocker 2204. Simultaneously, rocker 2204 shifts positioning rod 2205 in the opposite direction, thereby locking the circuit breaker rod fixed wheel 18. The circuit breaker opening / closing indicator gear 17 then displays the "open" position. Simultaneously, the circuit breaker opening / closing control intermittent gear 16 exits its travel range and no longer drives the bidirectional torsion spring energy storage gear 21, completing the opening operation.

[0066] In summary, inserting the operating handle into the operating handle latch shaft 7 drives the operating handle transmission gear 6 to move. The operating handle latch shaft 7, ball bearing transmission gear 10, transmission gear 1 13, transmission gear 2 14, circuit breaker rod 15, circuit breaker opening and closing control intermittent gear 16, circuit breaker opening and closing indication gear 17, ball bearing positioning gear 20, bidirectional torsion spring energy storage gear 21 and rack 23 cooperate with each other to drive the bidirectional torsion spring 19, and then complete the circuit breaker opening or closing energy storage and its action. Its structure is simpler than that of traditional circuit breakers, is easier to maintain, has high transmission accuracy, and can complete the opening and closing energy storage with only one bidirectional torsion spring.
