[0015] Compared with the prior art, the beneficial effects that the present invention can achieve are:

[0016] 1. For the power circuit breaker box with an elastic energy storage device, by arranging a top bead on the first arc-shaped plate, a clamping switch on the second energy storage toggle arm, and setting the bottom of the clamping switch as a clamping bead, and sleeving the clamping strip in the side groove, when the edge of the main arm body is worn after long-term use and cannot squeeze the downward pressing mechanism downward, due to the gravity effect, by the continuous rotation of the main arm body, the clamping strip makes an incomplete circular motion around the groove column. Through the incomplete motion of the clamping strip, when the clamping bead contacts the top bead, the top bead is squeezed by the clamping bead and moves downward, completing the contact between the downward pressing head and the contactor, avoiding the influence of component wear caused by long-term use on the energy storage process and the on-off effect.

[0017] 2. The power circuit breaker box with an elastic energy storage device, by setting the male downward pressing special-shaped plate and the female downward pressing special-shaped plate to face each other and match with a special shape, and arranging the triangular column in the groove formed by the male downward pressing special-shaped plate and the female downward pressing special-shaped plate. When the male downward pressing special-shaped plate and the female downward pressing special-shaped plate descend, due to the special structure of the male downward pressing special-shaped plate and the female downward pressing special-shaped plate, while squeezing the triangular column downward, the clamping force on both sides of the triangular column by the male downward pressing special-shaped plate and the female downward pressing special-shaped plate gradually decreases. Thus, when the triangular column and the third arc-shaped plate fixedly connected to the triangular column apply a downward pressure to the downward pressing head, an additional pressure caused by the gravity of the triangular column and the third arc-shaped plate fixedly connected to the triangular column is added, so that the downward pressing mechanism can better contact the downward pressing head, providing a double guarantee for the contact between the downward pressing head and the contactor, and improving the sensitivity of the device.

[0018] 3. The power circuit breaker box with an elastic energy storage device, through the special design of the male downward pressing special-shaped plate and the female downward pressing special-shaped plate. When the triangular column is lifted upward, the upper surface of the triangular column provides an upward force to the male downward pressing special-shaped plate and the female downward pressing special-shaped plate. Under the action of this force, the male downward pressing special-shaped plate and the female downward pressing special-shaped plate are squeezed and thus gradually approach each other, providing a clamping force on both sides of the triangular column to prevent the triangular column from falling during the rising process and improving the safety performance of the device.

[0019] 4. The power circuit breaker box with an elastic energy storage device, by setting the second rotating tooth column to match the external rotating column, connecting the moving handle to the groove column, and separating and combining the first rotating tooth column and the second rotating tooth column by moving the moving handle. When manual energy storage is required, first move the moving handle to combine the first rotating tooth column and the second rotating tooth column, and then rotate the external rotating column. The external rotating column drives the rotation of the second rotating tooth column, and uses the combination of the second rotating tooth column and the first rotating tooth column to drive the rotation of the first rotating tooth column, thereby driving the rotation of the groove column connected to the first rotating tooth column, and finally driving the rotation of the rotation connection column, thus completing the manual energy storage of the device.

[0020] 5. The power circuit breaker box with an elastic energy storage device, by designing the first arc-shaped plate to have the same shape as the lower edge of the second energy storage crank arm, increasing the contact area between the second energy storage crank arm and the first arc-shaped plate, enabling the downward pressure of the second energy storage crank arm to be better conducted, avoiding misaligned contact and sliding caused by the smooth edge when the second energy storage crank arm presses downward, and ensuring the stability of the contact between the second energy storage crank arm and the first arc-shaped plate.

[0041] The first energy storage mechanism 6 includes a one-way bearing 61, one end of the one-way bearing 61 is fixedly connected to the center of the first small gear 51, the other end of the one-way bearing 61 is connected to one end of a manual energy storage arm 64, the other end of the manual energy storage arm 64 is connected with a socket column 63 and a connecting ring 65, the socket column 63 is movably sleeved with one end of a long arm 62, the other end of the long arm 62 is sleeved with a connecting column 66, and the connecting column 66 penetrates through the long arm 62 and is connected to a motor 67.

[0042] Working principle:

[0043] First step, turn on the motor 67 to supply power to the second pinion 52 through the motor 67. After the second pinion 52 receives the power supply, it starts to rotate clockwise. The second pinion 52 meshes with the first pinion 51. The clockwise rotation of the second pinion 52 drives the first pinion 51 above it that meshes with the second pinion 52 to start rotating clockwise. There is a large gear 41 above the first pinion 51, and the first pinion 51 meshes with the large gear 41. When the first pinion 51 rotates clockwise, it will drive the rotation of the large gear 41 that meshes with the first pinion 51. The central position of the large gear 41 is fixedly connected to the energy storage large shaft 34. When the large gear 41 rotates clockwise, it drives the clockwise rotation of the energy storage large shaft 34 fixedly connected to the large gear 41. The energy storage large shaft 34 is fixedly connected to the second energy storage crank arm 33 and the first energy storage crank arm 32. When the energy storage large shaft 34 rotates, the first energy storage crank arm 32 and the second energy storage crank arm 33 connected to the energy storage large shaft 34 rotate clockwise. A rotating finger 31 is fixedly connected to the first energy storage crank arm 32. The rotation of the first energy storage crank arm 32 drives the rotating finger 31 to make a clockwise circular motion around the energy storage large shaft 34. The other end of the rotating finger 31 is fixedly connected to the movable connecting piece 23. When the rotating finger 31 rotates clockwise, the movable connecting piece 23 fixedly connected to the rotating finger 31 also starts to make a clockwise circular motion. The movable connecting piece 23 is fixedly connected to the lower end of the energy storage spring 22. The upper end of the energy storage spring 22 is connected to the fixed connecting piece 21. The upper end of the fixed connecting piece 21 is fixedly connected to the box body 1. The box body 1 is fixed and does not move, and the fixed connecting piece 21 also remains fixed. The upper end of the energy storage spring 22 connected to the fixed connecting piece 21 is fixed and does not move. The lower end of the energy storage spring 22 connected to the movable connecting piece 23 is stretched under the movement of the movable connecting piece 23. Moreover, the cam 42 on the closing gear assembly 4 catches the closing roller 43 fixed on the cam 42, so that the energy storage devices 2 and the closing gear assembly 4 at both ends of the energy storage rotating device 3 are in balance, thereby storing energy for the entire device.

[0044] Step 2: When the energy storage rotating device 3 in Step 1 starts to rotate clockwise, the second energy storage crank arm 33 in the energy storage rotating device 3 follows the energy storage rotating device 3 to rotate clockwise. When the second energy storage crank arm 33 rotates to the point where the smaller end of the second energy storage crank arm 33 is tangent to the downward pressing mechanism 36, the second energy storage crank arm 33 will squeeze the top bead 362 on the downward pressing mechanism 36. The top bead 362 is fixedly connected to the first arc-shaped plate 361, that is, the first arc-shaped plate 361 starts to move downward. A downward pressing column 363 is fixedly connected below the first arc-shaped plate 361. The downward pressing column 363 moves downward driven by the top bead 362. The downward pressing column 363 is fixedly connected to the second arc-shaped plate 364. The downward movement of the downward pressing column 363 drives the second arc-shaped plate 364 to move downward. The bottom of the downward pressing column 363 is also fixedly connected to the male downward pressing special-shaped plate 367. The movement of the downward pressing column 363 also drives the male downward pressing special-shaped plate 367 to move downward. When the male downward pressing special-shaped plate 367 moves downward, the female downward pressing special-shaped plate 368 facing and matching the male downward pressing special-shaped plate 367 is squeezed and jointly presses the triangular column 369 downward with the male downward pressing special-shaped plate 367. The triangular column 369 is fixedly connected to the third arc-shaped plate 3610. The downward moving triangular column 369 drives the third arc-shaped plate 3610 to perform a downward pressing action. After the third arc-shaped plate 3610 is pressed downward, the downward pressing head 373 arranged below the third arc-shaped plate 3610 is squeezed by the third arc-shaped plate 3610. And during the downward pressing process, the clamping action of the male downward pressing special-shaped plate 367 and the female downward pressing special-shaped plate 368 on the triangular column 369 gradually decreases as the male downward pressing special-shaped plate 367 and the female downward pressing special-shaped plate 368 separate. As a result, the gravity of the triangular column 369 and the third arc-shaped plate 3610 fixedly connected to the triangular column 369 exerts a downward pressure on the downward pressing head 373, thereby driving the downward pressing of the downward pressing head 373, completing the contact between one end of the rocker 371 fixedly connected to the downward pressing head 373 and the contactor 372, and thus completing the energy storage of the device. When the device releases the energy storage, the upwardly lifted third arc-shaped plate 3610 and triangular column 369 will squeeze the male downward pressing special-shaped plate 367 and the female downward pressing special-shaped plate 368 in contact with them upward. The upwardly squeezed male downward pressing special-shaped plate 367 and female downward pressing special-shaped plate 368 gradually approach each other. During the approaching process, the clamping force on the triangular column 369 gradually increases, ensuring that the triangular column 369 and the third arc-shaped plate 3610 do not fall off during the energy release process.

[0045] Step 3. During the previous step, due to the long-term use of the machine, wear may occur between components, making the extrusion contact between the second energy storage toggle arm 33 and the downward pressing mechanism 36 insensitive, and unable to complete the downward extrusion of the second energy storage toggle arm 33 on the downward pressing mechanism 36. As a result, the downward pressing head 373 and the contactor 372 cannot make contact or the contact is incomplete. When such a situation occurs, the second energy storage toggle arm 33 cannot extrude the downward pressing mechanism 36 when passing above the downward pressing mechanism 36, and thus continues to rotate clockwise. When the second energy storage toggle arm 33 rotates to a certain angle, a clamping switch 333 is provided in the side groove 332 of the second energy storage toggle arm 33. The clamping bar 3332 in the clamping switch 333 makes an incomplete circular motion around the groove column 3331 under the action of gravity with the rotation of the main arm body 331. A clamping bead 3333 is fixedly connected below the clamping bar 3332. When the clamping bead 3333 meets the top bead 362, the clamping bead 3333 extrudes the top bead 362, replacing the downward pressure exerted by the second energy storage toggle arm 33 on the downward pressing mechanism 36 to complete the electric energy storage process.

[0046] Step 4. When performing manual energy storage, first move the movable handle 75 in the direction as shown in Figure 7 . The movable handle 75 is connected to the groove column 74. One end of the groove column 74 is fixedly connected to the first rotating tooth column 76. Engage the first rotating tooth column 76 with the second rotating tooth column 77, and then rotate the external rotating column 78 counterclockwise. The rotation of the external rotating column 78 drives the rotation of the second rotating tooth column 77, thereby driving the rotation of the first rotating tooth column 76 engaged with the second rotating tooth column 77. The first rotating tooth column 76 is fixedly connected to the groove column 74. The groove column 74 rotates under the drive of the first rotating tooth column 76. The groove column 74 is fixedly connected to the buffer column 73. The buffer column 73 is fixedly connected to the safety spring 72. The safety spring 72 is fixedly connected to the rotating connection column 71. When the groove column 74 rotates, the rotating connection column 71 also rotates accordingly. The rotating connection column 71 is fixedly connected to the connection column 66. Under the rotation of the rotating connection column 71, the connection column 66 starts to rotate. The other end of the connection column 66 is fixedly connected to the long arm 62. Driven by the connection column 66, the long arm 62 fixedly connected to the connection column 66 moves in the direction as shown in Figure 6 . When the long arm 62 moves in the direction shown in the figure, the manual energy storage arm 64 sleeved with the long arm 62 through the socket column 63 will rotate counterclockwise, driving the counterclockwise rotation of the one-way bearing 61 connected to the manual energy storage arm 64. The one-way bearing 61 is fixedly connected to the first small gear 51, thereby driving the counterclockwise rotation of the first small gear 51. The first small gear 51 meshes with the closing gear assembly 4. Driven by the first small gear 51, the closing gear assembly 4 rotates counterclockwise. The same as in Step 1, the energy storage of the device is completed by the stretching of the energy storage spring 22.

[0047] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto, and various changes can be made without departing from the spirit of the present invention within the scope of knowledge possessed by those skilled in the art.
