Abstract

The present invention relates to the technical field of emergency protection circuit devices, and specifically to a reclosing switch with an automatic control function, including a gate housing, a motor, an energy storage capacitor, an input gear, an output gear, a gear energy storage assembly, and a locking assembly. The motor is arranged in the gate housing, and the energy storage capacitor is also arranged in the gate housing. The energy storage capacitor is electrically connected to the motor and is used to drive the motor to rotate. The present invention is provided with a gear energy storage assembly and a locking assembly. When the circuit is working normally, the gear energy storage assembly and the energy storage capacitor store energy at the same time. At this time, the sum of the kinetic energy that can drive the output gear to rotate is the sum of the electric energy provided by the energy storage capacitor and the kinetic energy stored by the gear energy storage assembly. Therefore, it is equivalent to mechanically expanding the energy storage capacitor, so that more electric energy can be provided to ensure the normal operation of the reclosing switch in the case of power failure, and there will be no negative effects such as slow response speed, complex charging control system, and frequent maintenance due to the expansion.

Description

Technical Field

[0001] The invention relates to the technical field of emergency protection circuit devices, in particular to a reclosing switch with an automatic control function. Background Art

[0002] The reclosing device is an important device used in power systems to automatically restore power lines that have been disconnected. When a fault occurs in the power system, the protection device will quickly operate to trip the circuit breaker and cut off the faulty circuit. After a certain time delay, the reclosing device will try to reclose the circuit breaker to restore power. If the circuit fault has been eliminated, the reclosing device will be able to push the circuit breaker to close and restore normal power supply. If the circuit fault has not been eliminated, the circuit breaker will trip again after the reclosing device pushes the circuit breaker to close.

[0003] Most existing reclosing devices use capacitor energy storage to provide power for the reclosing device, allowing the reclosing device to drive the circuit breaker to open and close in the event of a power outage. If the fault time is long, the reclosing device will consume more electrical energy by driving the circuit breaker to open and close multiple times. This requires the capacitor to store more electrical energy. However, the capacitor capacity of the reclosing device cannot be too large. Excessive capacitance will not only delay the response speed of the reclosing device, but also require a more complex charging control system to manage the capacitor, as well as more frequent inspections and maintenance to ensure the stability of the capacitor. Therefore, the kinetic energy that can be provided by capacitor energy storage alone is limited, and normal operation cannot be guaranteed in the event of a long power outage. Summary of the invention

[0004] Based on this, it is necessary to provide a reclosing switch with an automatic control function to address the problems existing in the current reclosing switch, so as to solve the problem that the existing reclosing switch cannot drive the circuit breaker to open and close normally when the fault time is long.

Moreover, a first feature being "above", "above" or "above" a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature.

[0060] like Figure 1-Figure 14As shown, the reclosing switch with automatic control function is used to control the opening and closing of the relay. The reclosing switch with automatic control function includes a gate body housing 100, a motor 200, an energy storage capacitor, an input gear 310, an output gear 320, a gear energy storage assembly 400 and a locking assembly 500. The motor 200 is arranged in the gate body housing 100, and the energy storage capacitor is also arranged in the gate body housing 100. The energy storage capacitor is electrically connected to the motor 200 and is used to drive the motor 200 to rotate. The input gear 310 is rotatably arranged in the gate body housing 100 and is transmission-connected to the output end of the motor 200. The output gear 320 is rotatably arranged in the gate body housing 100. The output gear 320 is transmission-connected to the gate rod 990. The gate rod 990 is rotatably arranged in the gate body housing 100. The output gear 320 controls the rotation of the gate rod 990 to control the closing of the relay. The gear energy storage assembly 400 is in the In the gate body housing 100, the gear energy storage assembly 400 is connected to the input gear 310 and the output gear 320 in a one-way transmission manner, and the gear energy storage assembly 400 is configured so that when the input gear 310 rotates counterclockwise, the input gear 310 drives the gear energy storage assembly 400 to rotate, and the gear energy storage assembly 400 stores energy. At the same time, the output gear 320 does not rotate. When the kinetic energy of the gear energy storage assembly 400 is released, the gear energy storage assembly 400 drives the output gear 320 to rotate, and the input gear 310 does not rotate. The locking assembly 500 has a locking state and a non-locking state. In the locking state, the locking assembly 500 limits the kinetic energy release of the gear energy storage assembly 400. In the non-locking state, the locking assembly 500 cancels the restriction on the kinetic energy release of the gear energy storage assembly 400, and the gear energy storage assembly 400 releases the kinetic energy to drive the output gear 320 to rotate.

[0061] When the circuit is working normally, the energy storage capacitor supplies power to the motor 200, driving the output end of the motor 200 to rotate. The output end of the motor 200 drives the input gear 310 to rotate counterclockwise through transmission cooperation, and the input gear 310 drives the gear energy storage assembly 400 to rotate, so that the gear energy storage assembly 400 completes energy storage. During the energy storage process of the gear energy storage assembly 400, the locking assembly 500 is in a locked state to limit the release of kinetic energy of the gear energy storage assembly 400. After the gear energy storage assembly 400 completes energy storage, the energy storage capacitor continues to charge. After the energy storage capacitor is fully charged, the sum of the kinetic energy that can drive the output gear 320 to rotate is the sum of the electrical energy provided by the energy storage capacitor and the kinetic energy stored in the gear energy storage assembly 400. Therefore, it is equivalent to mechanically expanding the energy storage capacitor, thereby being able to provide more electrical energy to ensure the normal operation of the reclosing switch in the case of power failure, and will not cause negative effects such as slow response speed, complex charging control system and frequent maintenance due to capacity expansion.

[0062] In the event of a circuit fault, the control module in the reclosing switch controls the locking assembly 500 to operate, so that the locking assembly 500 switches from a locked state to a non-locked state. At this time, the kinetic energy of the gear energy storage assembly 400 is released, and the gear energy storage assembly 400 drives the output gear 320 to rotate through transmission cooperation, and the output gear 320 drives the gate rod 990 to rotate through transmission cooperation, thereby controlling the closing of the relay through the rotation of the gate rod 990, while the input gear 310 does not rotate. If the fault has been eliminated, the gate rod 990 will no longer pop open, the circuit is connected, and the energy storage capacitor drives the motor 200 to rotate to charge the gear energy storage assembly 400. The energy storage capacitor is fully charged again. If the fault still exists , the gate rod 990 is still bounced to the position before rotation. After a certain time interval, the energy storage capacitor supplies power to the motor 200 so that the gear energy storage assembly 400 completes energy storage. After the gear energy storage assembly 400 completes energy storage, the gear energy storage assembly 400 releases kinetic energy again to drive the gate rod 990 to rotate. If the fault is still not eliminated, after a certain time interval, the energy storage capacitor continues to supply power to the motor 200 so that the gear energy storage assembly 400 completes energy storage. After the gear energy storage assembly 400 stores energy, the gear energy storage assembly 400 releases kinetic energy again to drive the gate rod 990 to rotate until the fault is eliminated or the remaining electric energy of the energy storage capacitor is insufficient to drive the gate rod 990 to rotate.

[0063] In a further embodiment, Figure 5-Figure 7 As shown, the gear energy storage assembly 400 includes a first fixed column 411, a second fixed column 431, a third fixed column 442 and a first rotating column 421. The first fixed column 411, the second fixed column 431 and the third fixed column 442 are arranged in the gate housing 100 at intervals, and the first rotating column 421 is rotatably arranged in the gate housing 100;

[0064] The first fixed column 411 is externally rotatably connected with a first ratchet wheel 412 and a second ratchet wheel 413 which are coaxially integrally formed. A first annular groove is provided in the first ratchet wheel 412, and a first coil spring 4121 is installed in the first annular groove. One end of the first coil spring 4121 is arranged on the first fixed column 411, and the other end of the first coil spring 4121 is arranged on the peripheral wall of the first annular groove. The outer side of the first ratchet wheel 412 is matched with a first ratchet ring 414 for one-way transmission, and the first ratchet ring 414 is configured so that when the first ratchet wheel 412 is rotated, the first ratchet ring 414 is rotated to rotate in a direction opposite to the first fixed column 411. When the ratchet wheel 412 rotates counterclockwise and the rotational resistance of the first ratchet ring 414 is less than a first preset value, the first ratchet ring 414 rotates synchronously with the first ratchet wheel 412; when the first ratchet wheel 412 rotates clockwise and the rotational resistance of the first ratchet ring 414 is greater than the first preset value, the first ratchet ring 414 rotates relatively with the first ratchet wheel 412; the first ratchet ring 414 is further configured to rotate synchronously with the first ratchet wheel 412 when the first ratchet wheel 412 rotates clockwise;

[0065] The output gear 320 is coaxially arranged on the outside of the first rotating column 421. The first gear 422 is sleeved on the outside of the first rotating column 421 through a first one-way bearing. The first one-way bearing is configured so that when the first gear 422 rotates clockwise, the first gear 422 and the first rotating column 421 rotate relatively through the first one-way bearing. When the first gear 422 rotates counterclockwise, the first gear 422 and the first rotating column 421 rotate synchronously through the first one-way bearing. An annular tooth groove is provided on the outer side of the first ratchet ring 414. The first ratchet ring 414 meshes with the first gear 422 through the annular tooth groove.

[0066] The second fixed column 431 is externally rotatably connected with a coaxially integrally formed second gear 432 and a third ratchet 433 , and the third ratchet 433 cooperates with the second ratchet 413 ;

[0067] The outside of the third fixed column 442 is rotatably connected to the first rotating cylinder 441, and the input gear 310 is coaxially arranged on the outside of the first rotating cylinder 441. The outside of the first rotating cylinder 441 is provided with a third gear 443 through a second one-way bearing sleeve, and the second one-way bearing is configured so that when the third gear 443 rotates counterclockwise, the third gear 443 and the first rotating cylinder 441 rotate synchronously through the second one-way bearing, and when the third gear 443 rotates clockwise, the third gear 443 and the first rotating cylinder 441 rotate relative to each other through the second one-way bearing, and the third gear 443 is meshed with the second gear 432.

[0068] When the gear energy storage assembly 400 is storing energy, the input gear 310 rotates counterclockwise, the first rotating cylinder 441 and the third gear 443 rotate counterclockwise synchronously, and the third gear 443 drives the second gear 432 to rotate clockwise. Since the second gear 432 and the third ratchet 433 are coaxially integrated, the third ratchet 433 drives the second ratchet 413 to rotate counterclockwise. Since the second ratchet 413 and the first ratchet 412 are coaxially integrated, the first ratchet 412 rotates counterclockwise. Since the first fixing column 411 is fixed in the brake body housing 100, the first coil spring 4121 is tightened to store energy. At the same time, the locking assembly 500 The gear energy storage assembly 400 has not been locked yet, so the rotational resistance of the first ratchet ring 414 is less than the first preset value, and the first ratchet wheel 412 drives the first ratchet ring 414 to rotate synchronously, and the counterclockwise rotation of the first ratchet ring 414 drives the first gear 422 to rotate clockwise. At this time, the first gear 422 and the first rotating column 421 rotate relative to each other, that is, the first rotating column 421 does not rotate. When the locking assembly 500 locks the gear energy storage assembly 400, the first ratchet ring 414 cannot rotate. At this time, even if the first ratchet wheel 412 continues to rotate under the action of inertia after the motor 200 stops, it cannot drive the first ratchet ring 414 to rotate.

[0069] When the kinetic energy of the gear energy storage assembly 400 is released, the locking assembly 500 no longer locks the gear energy storage assembly 400, and the first ratchet ring 414 can rotate. At this time, the elastic potential energy of the first coil spring 4121 is converted into kinetic energy, driving the first ratchet wheel 412 to rotate clockwise, and the first ratchet ring 414 and the first ratchet wheel 412 rotate clockwise synchronously, so under the driving action of the first ratchet ring 414, the first gear 422 rotates counterclockwise, and at this time, under the action of the first one-way bearing, the first rotating column 421 rotates counterclockwise synchronously, so the first rotating column 421 drives the output gear 320 to rotate counterclockwise synchronously, and the output gear 320 drives the gate rod 990 to rotate through transmission cooperation, thereby controlling the closing of the relay through the rotation of the gate rod 990.

[0070] It should be added that the first rotating column 421 and the output gear 320 should also be connected via a one-way bearing, and the one-way bearing is configured so that when the first rotating column 421 rotates counterclockwise, the first rotating column 421 and the output gear 320 rotate synchronously, and when the first rotating column 421 rotates clockwise, the first rotating column 421 and the output gear 320 rotate relative to each other. This is configured because if the circuit fault is not eliminated, when the gate lever 990 is bounced open, the output gear 320 will be driven to rotate in the opposite direction, that is, clockwise, through transmission cooperation.

[0071] In a further embodiment, Figure 5 , Fig. 9 , Fig.10 and Fig.14 As shown, the locking assembly 500 includes a supporting main rod 510, a connecting plate 520 and a sliding limiting column 530. The supporting main rod 510 is arranged inside the gate body shell 100, and the supporting main rod 510 can move along its axial direction. The connecting plate 520 is arranged on the supporting main rod 510. A sliding groove 521 is provided on the connecting plate 520. The long axis axis of the sliding groove 521 extends along the radial direction of the first ratchet ring 414. The upper surface of the first ratchet ring 414 is provided with a first vortex groove 540. The end of the first vortex groove 540 away from the center of the circle is provided with a first limiting circular groove 541. The first limiting circular groove 541 is provided with a first vortex groove 540. 1 is connected to the first vortex groove 540, and the diameter of the first limiting circular groove 541 is greater than the width of the first vortex groove 540. The sliding limiting column 530 includes a middle diameter column 531 and a large diameter column 532. The middle diameter column 531 and the large diameter column 532 are coaxially fixedly connected. The middle diameter column 531 is slidably connected in the sliding groove 521 and the first vortex groove 540 at the same time. When the middle diameter column 531 slides along the first vortex groove 540 to the first limiting circular groove 541, the support main rod 510 can move along its axis so that the large diameter column 532 is stuck in the first limiting circular groove 541.

[0072] It should also be noted that the purpose of setting the locking component 500 is also to control the amount of energy storage through the locking component 500, so that after the kinetic energy of the gear energy storage component 400 is released, the angle of rotation of the output gear 320 is just enough to make the rotation angle of the gate rod 990 control the relay to close.

[0073] Specifically, before the first coil spring 4121 stores energy, the middle diameter column 531 is located at one end of the first vortex groove 540 close to the center of the circle. When storing energy, the first ratchet wheel 412 rotates counterclockwise, and the first ratchet wheel 412 drives the first ratchet ring 414 to rotate counterclockwise. Under the joint guidance of the first vortex groove 540 and the sliding groove 521, the middle diameter column 531 gradually moves away from the center of the circle of the first vortex groove 540. When the middle diameter column 531 moves to the end of the first vortex groove 540 away from the center of the circle, the large diameter column 532 is coaxial with the first limiting circular groove 541. At this time, the control module of the reclosing brake controls The control support main rod 510 drives the connecting plate 520 and the sliding limit column 530 to move upward synchronously, so that the large diameter column 532 is stuck in the first limit circular groove 541. At this time, the first ratchet ring 414 no longer rotates. Since the first ratchet ring 414 and the first ratchet wheel 412 rotate synchronously clockwise, when the first ratchet ring 414 cannot rotate, the first ratchet wheel 412 cannot rotate either. At this time, the elastic potential energy of the first coil spring 4121 is converted into kinetic energy and released to drive the output gear 320 to rotate at an angle that just allows the rotation angle of the gate rod 990 to control the closing of the relay.

[0074] When the kinetic energy of the gear energy storage assembly 400 is to be released, the control module of the reclosing switch controls the support main rod 510 to move downward along its axis so that the large diameter column 532 disengages from the first limiting circular groove 541. After the large diameter column 532 disengages from the first limiting circular groove 541, under the action of the first coil spring 4121, the first ratchet 412 rotates clockwise, and the first ratchet 412 drives the first ratchet ring 414 to rotate clockwise synchronously, so that the medium diameter column 531 gradually moves along the first vortex groove 540 to the end close to the center of the first vortex groove 540, and the sliding limiting column 530 is reset.

[0075] It should be further explained that, in order to enable the support main rod 510 to move along its axis direction, specifically, a first electric telescopic rod 550 is provided in the gate body housing 100, and the telescopic end of the first electric telescopic rod 550 is coaxially fixedly connected to the support main rod 510, and the control module of the reclosing switch is electrically connected to the first electric telescopic rod 550, which is used to control the extension or shortening of the first electric telescopic rod 550. When it is necessary to move the support main rod 510 along its axis so that the large diameter column 532 moves into the first limiting circular groove 541, the telescopic end of the first electric telescopic rod 550 is extended, and the telescopic belt of the first electric telescopic rod 550 drives the support main rod 510 to move, so that the large diameter column 532 moves into the first limiting circular groove 541. On the contrary, when the large diameter column 532 needs to be moved out of the first limiting circular groove 541 , the telescopic end of the first electric telescopic rod 550 drives the supporting main rod 510 to move in the opposite direction, so that the large diameter column 532 is moved out of the first limiting circular groove 541 .

[0076] In a further embodiment, Figure 5 As shown, the reclosing switch with automatic control function also includes a balancing component 600, which is used to balance the circumferential force of the sliding limiting column 530 when the large diameter column 532 is stuck in the first limiting circular groove 541.

[0077] It can be understood that when the gear energy storage assembly 400 is in the energy storage state, the sliding limit column 530 is subjected to a clockwise torque from the first coil spring 4121. Under long-term action, the sliding limit column 530 may be deformed. Therefore, it is necessary to provide the sliding limit column 530 with an equal force in opposite direction to form a pair of balancing forces so that the sum of the torques received by the sliding limit column 530 in the circumferential direction is zero. Therefore, a balancing assembly 600 is provided. When the large diameter column 532 is stuck in the first limiting circular groove 541 through the balancing assembly 600, the circumferential force of the sliding limit column 530 is balanced.

[0078] In a further embodiment, Figure 5 , Figure 7-Figure 12As shown, the balancing assembly 600 includes a fourth ratchet 610, a fifth ratchet 620 and a second ratchet ring 630. The fourth ratchet 610 and the fifth ratchet 620 are coaxially connected as a whole. A second annular groove is provided in the fourth ratchet 610. A second coil spring 631 is installed in the second annular groove. One end of the second coil spring 631 is arranged on the first fixing column 411, and the other end of the second coil spring 631 is arranged on the peripheral wall of the second annular groove. An annular ratchet groove is also provided on the inner peripheral surface of the second ratchet ring 630. The fourth ratchet 610 is located at the second ratchet ring 630. The inner side of the ring 630 is in transmission cooperation with the second ratchet ring 630, the second vortex groove 640 and the first vortex groove 540 have opposite rotation directions, the width of the second vortex groove 640 is smaller than the width of the first vortex groove 540, and the end of the second vortex groove 640 away from the center of the circle is provided with a second limiting circular groove 641, the diameter of the second limiting circular groove 641 is the same as the width of the first vortex groove 540, and the sliding limiting column 530 also includes a small diameter column 533, and the small diameter column 533 is coaxially arranged on the middle diameter column 531 away from the large diameter column 53 2, when the middle diameter column 531 slides into the first limiting circular groove 541 along the first vortex groove 540, the small diameter column 533 slides into the second limiting circular groove 641, and the main rod 510 is supported to move along its axis, so that the large diameter column 532 is stuck in the first limiting circular groove 541, and the middle diameter column 531 is stuck in the second limiting circular groove 641. The balancing assembly 600 also includes a first bevel gear 650, a second bevel gear 660, a third bevel gear 670 and a sixth ratchet 680. The first bevel gear 650 is coaxially integrally formed with the second gear 432, the second bevel gear 660 is rotatably set on the second fixed column 431, the axis of the second bevel gear 660 is perpendicular to the axis of the second fixed column 431, the second bevel gear 660 is meshed with the first bevel gear 650, the sixth ratchet 680 is rotatably set outside the second fixed column 431, the third bevel gear 670 and the sixth ratchet 680 are coaxially integrally formed, the third bevel gear 670 is meshed with the second bevel gear 660, and the sixth ratchet 680 is transmission-coordinated with the fifth ratchet 620.

[0079] When the first coil spring 4121 accumulates energy clockwise, the second gear 432 rotates counterclockwise. Under the transmission action of the first bevel gear 650, the second bevel gear 660 and the third bevel gear 670, the sixth ratchet 680 rotates clockwise. The clockwise rotation of the sixth ratchet 680 drives the fifth ratchet 620 to rotate counterclockwise. Since the fourth ratchet 610 and the fifth ratchet 620 are coaxially formed as one piece, the fourth ratchet 610 rotates counterclockwise, and the second coil spring 631 inside the fourth ratchet 610 rotates counterclockwise to tighten. At the same time, the counterclockwise rotation of the fourth ratchet 610 pushes the second ratchet ring 630 to rotate counterclockwise. At the same time, due to the clockwise rotation of the first ratchet ring 414 and the first vortex groove 540 The rotation direction is opposite to that of the second vortex groove 640, so the sliding limit column 530 gradually moves away from the center of the first vortex groove 540 and the second vortex groove 640 along the first vortex groove 540 and the second vortex groove 640 until the sliding limit column 530 moves to the end of the first vortex groove 540 and the second vortex groove 640 away from the center of the circle. At this time, the motor 200 stops rotating, the first ratchet ring 414 and the second ratchet ring 630 stop rotating, and then the supporting main rod 510 moves upward along its axis, so that the large diameter column 532 is clamped into the first limiting circular groove 541, and the medium diameter column 531 is clamped into the second limiting circular groove 641. At this time, the sliding limit column 530 is subjected to balanced circumferential force.

[0080] In a further embodiment, Figure 6 As shown, there are multiple gear energy storage assemblies 400, multiple locking assemblies 500 and balancing assemblies 600, and the multiple gear energy storage assemblies 400, multiple locking assemblies 500 and balancing assemblies 600 are arranged at intervals along the vertical direction and correspond to each other one by one.

[0081] This configuration is to increase kinetic energy so that the output gear 320 can be driven to rotate more times, so as to adapt to a longer fault time.

[0082] In a further embodiment, Figure 6 , Figure 7 and Fig.13 As shown, a fourth fixed column 710 is further provided in the gate body housing 100, and the first rotating cylinder 441 is rotatably arranged on the outside of the fourth fixed column 710. A limited straight-through groove 4411 is provided on the outside of the first rotating cylinder 441, and the limited straight-through groove 4411 extends along the axis of the first rotating cylinder 441. A spiral groove 711 is provided on the outside of the fourth fixed column 710, and a guide boss 720 is provided on the inner circumferential wall of the first one-way bearing. The guide boss 720 passes through the limited straight-through groove 4411 and is slidably connected in the spiral groove 711. The depths of the first limiting circular groove 541 and the second limiting circular groove 641 increase from the end away from the first electric telescopic rod 550 to the end close to the first electric telescopic rod 550.

[0083] It should also be noted that, in order to simplify the structure of the plurality of locking assemblies 500 , specifically, a plurality of connecting plates 520 may be arranged on a supporting main rod 510 at intervals along the axis of the supporting main rod 510 .

[0084] When the input gear 310 rotates counterclockwise, the first rotating cylinder 441 rotates counterclockwise synchronously. Under the guidance of the limiting straight-through groove 4411, the spiral groove 711 and the guiding protruding column 720, the third gear 443 rotates counterclockwise and moves upward along the axis of the first rotating cylinder 441. When the third gear 443 moves upward until the third gear 443 is out of mesh with the second gear 432 at the bottom, the supporting main rod 510 moves upward a short distance. At this time, the middle diameter column 531 and the large diameter column 532 in the sliding limiting column 530 corresponding to the large diameter column 531 are engaged with each other. 2 are respectively engaged in the second limiting circular groove 641 and the first limiting circular groove 541, at which time the elastic potential energy of the lowest first coil spring 4121 is locked. In this way, as the third gear 443 moves upward along the axis of the first rotating cylinder 441, whenever the third gear 443 is disengaged from the currently meshed second gear 432, the supporting main rod 510 moves upward by a certain distance, so that the corresponding sliding limiting column 530 locks the corresponding first vortex groove 540 and the second ratchet ring 630, thereby completing the gradual tightening and energy storage of the plurality of first coil springs 4121 and the second coil spring 631.

[0085] When the kinetic energy is released, the support main rod 510 first moves downward for a short distance, so that the middle diameter column 531 and the large diameter column 532 of the uppermost sliding limit column 530 first move out of the corresponding second limit circular groove 641 and the first limit circular groove 541. At this time, the kinetic energy of the uppermost first coil spring 4121 is released, and the uppermost first ratchet wheel 412 drives the first ratchet ring 414 to rotate clockwise, thereby driving the corresponding first gear 422 to rotate counterclockwise, and then drives the first rotating column 421 to rotate counterclockwise, thereby driving the output gear 320 to rotate counterclockwise synchronously, and the output gear 320 drives the gate rod 990 to rotate through transmission cooperation, thereby controlling the closing of the relay through the rotation of the gate rod 990. As the support main rod 510 gradually moves downward, the kinetic energy of each first coil spring 4121 from top to bottom is released in sequence to drive the corresponding first gear 422 to rotate, until the kinetic energy of all the first coil springs 4121 is released or after the circuit fault is eliminated, the support main rod 510 stops moving downward.

[0086] After all the first coil springs 4121 and the second coil springs 631 have completed energy storage, the input gear 310 rotates clockwise. At this time, under the guidance of the limiting straight-through groove 4411, the spiral groove 711 and the guide boss 720, the first one-way bearing drives the third gear 443 to move downward to the lowest point, that is, the third gear 443 is meshed with the lowest second gear 432.

[0087] It should also be noted that the ratchet teeth of the first ratchet 412, the second ratchet 413, the third ratchet 433, the fourth ratchet 610, the fifth ratchet 620, the sixth ratchet 680 and the first ratchet ring 414 and the second ratchet ring 630 in the present invention are all rubber teeth, and the friction force between the rubber teeth of the two ratchet wheels that cooperate with each other satisfies that before the sliding limit column 530 moves to the end of the first vortex groove 540 away from its center of circle, the two ratchet wheels that cooperate with each other can rotate synchronously clockwise or counterclockwise. Taking the cooperation between the first ratchet 412 and the first ratchet ring 414 as an example, when the first coil spring 4121 accumulates force, the first ratchet 412 rotates counterclockwise. When the first ratchet 412 rotates clockwise, since the sliding limit post 530 has not moved to the end of the first vortex groove 540 away from the center of the circle, the friction between the rubber teeth can also push the first ratchet ring 414 to rotate synchronously with the first ratchet 412 when the first ratchet 412 rotates counterclockwise. When the sliding limit post 530 moves to the end of the first vortex groove 540 away from the center of the circle, the motor 200 stops rotating. At this time, under the action of inertia, the first ratchet 412 will continue to rotate a certain angle, while the first ratchet ring 414 has been fixed. Therefore, at this time, the first ratchet 412 and the first ratchet ring 414 rotate relative to each other at a certain angle to prevent the motor 200 from locking.

[0088] It should be noted that the transmission connection between the motor 200 and the input gear 310 is as follows. Specifically, Figure 5 As shown, the output shaft of the motor 200 is fixedly connected to the first transmission gear 810 , and a second transmission gear 820 is rotatably arranged in the gate housing 100 . The second transmission gear 820 is coaxially arranged with the worm rod 830 , and the worm rod 830 is meshed with the input gear 310 .

[0089] When the coil spring is charged, the output shaft of the motor 200 drives the first transmission gear 810 to rotate, the first transmission gear 810 drives the second transmission gear 820 to rotate, the second transmission gear 820 drives the worm 830 to rotate, and the worm 830 drives the input gear 310 to rotate, so that the input gear 310 rotates counterclockwise.

[0090] It should be noted that the transmission connection between the output gear 320 and the gate rod 990 is as follows. Specifically, Figure 4 and Figure 5As shown, a driving wheel 910 is also rotatably arranged in the gate housing 100, and a cam 920 is coaxially connected to the driving wheel 910, and the cam 920 is connected to the sliding plate 930, and the sliding plate 930 is slidably connected to the upper part of the gate housing 100, and a swing frame 940 is arranged at the lower part of the sliding plate 930, and the swing frame 940 can rotate around its rotation fulcrum 901 as the rotation axis, and the lower part of the swing frame 940 is hinged with a tension spring 980, and the other end of the tension spring 980 is hinged to the second movable plate 960 through the third hinge point 904, and the gate housing 100 is also hinged with the first hinge point 902 as the hinge point A third movable plate 970 is hinged, and the third movable plate 970 is connected to the second movable plate 960. The lower part of the third movable plate 970 is hinged with the first movable plate 950 at the third hinge point 904 as the hinge point. The first movable plate 950 is arranged on the gate rod 990, and the gate rod 990 is hinged on the gate body shell 100 at the second hinge point 903 as the hinge point. A metal contact 991 is arranged on the gate body shell 100 and below the gate rod 990. When the metal contact 991 contacts the gate rod 990, the relay is energized. When the metal contact 991 does not contact the gate rod 990, the circuit is disconnected.

[0091] When in use, when the elastic potential energy of the coil spring is converted into kinetic energy and released, the output gear 320 rotates counterclockwise, the driving wheel 1 910 rotates clockwise, the sliding plate 930 moves to the right, and the swing frame 940 swings to the right around the rotating fulcrum 901. Through the first movable plate 950, the second movable plate 960, the third movable plate 970 and the tension spring 980, the gate rod 990 rotates to the right around the second hinge point 903, so that the gate rod 990 contacts the metal contact 991 and the circuit is connected. When a fault occurs, the gate rod 990 is bounced open until it is no longer in contact with the metal contact 991, and the circuit is disconnected. How the gate rod 990 is bounced open is a prior art, such as electromagnetic force drive, thermal tripping and magnetic tripping.

[0092] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0093] The above-described embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
