Description

Technical Field

[0001] This application relates to the field of distribution box technology, and in particular to a fast-power-off integrated distribution box. Background Technology

[0002] With the continuous growth of electricity demand and the rapid development of power technology, integrated distribution boxes, as an important component of the power system, are also constantly improving in terms of function and performance. Integrated distribution boxes not only have the functions of power distribution and management, but also realize the functions of power monitoring, control and remote communication, providing a strong guarantee for the stable operation of the power system.

[0003] Chinese Patent Publication No. CN222127265U discloses a busbar integrated distribution box, including a box body and a door installed on the box body. The box body has a horizontal plate and a support frame for supporting the two ends of the horizontal plate. A busbar circuit breaker is installed on the side of the horizontal plate. The busbar circuit breaker includes a circuit breaker body and a busbar on the upper side of the circuit breaker body. Due to the integrated installation of the circuit breaker body and the busbar, this application eliminates the need for additional transition terminals when placing the busbar circuit breaker inside the integrated distribution box. This effectively reduces the required space and allows for more rational use of the space inside the integrated distribution box, thereby improving the space utilization rate of the integrated distribution box.

[0004] While existing technologies have improved the space utilization rate inside the distribution box, when a fault occurs in the distribution box, although the circuit breaker can cut off the power immediately, there may be residual power inside the power module group. This increases the safety risk for maintenance workers when they carry out emergency repairs, and also increases the difficulty of emergency repairs. Utility Model Content

[0005] This application provides a fast-power-off integrated distribution box, which can improve the technical problem in related technologies where, although the circuit breaker can cut off the power immediately when the distribution box fails, there may be residual power inside the power module group, which increases the safety risk for maintenance workers when they carry out emergency repairs.

[0006] This application provides a fast power-off integrated distribution box, including a distribution box shell, a cabinet door rotatably connected to one side of the front end of the distribution box shell, a power module group provided in the inner cavity of the distribution box shell, and a fast power-off component rotatably connected to the front end of the power module group; The rapid power-off assembly includes a rotating end rotatably connected to the power module group. A transmission column is fixedly connected to the other side of the rotating end. The transmission column rotates inside both sides of the power module group. A drive gear is fixedly connected to the outer wall of the other end of the transmission column. A worm gear is meshed and rotatably connected to one side of the drive gear. Two driven columns are fixedly connected to both ends of the worm gear. A retaining ring is fixedly connected to the upper end of the driven column at the upper end. A push end is fixedly connected to the upper end of the retaining ring. Multiple aviation plugs are provided at the upper end of the power module group. An aircraft carrier plug is snapped into the upper end of the aviation plug. A parallel plate is fixedly connected to the outer wall of the aircraft carrier plug near the center. The upper end of the push end is attached to the parallel plate.

[0007] By adopting the above technical solution, when a fault occurs inside the distribution box and power is cut off, the rotating end is turned, which drives the transmission column to rotate. At the same time, the rotation drives the drive gear behind the power module group. The drive gear rotates, which drives the worm gear to rotate. This causes the push column at the upper end of the worm gear to move upward and push the parallel plate on the outside of the aircraft carrier plug, so that the aircraft carrier plug is disconnected from the aviation plug and the power transmission is canceled, resulting in a physical disconnection state. This completely avoids the risk of maintenance personnel accidentally touching live parts. It is especially suitable for emergency repair scenarios where power is not completely cut off. At the same time, the use of the aviation plug makes the connection between lines stable and quick, and also facilitates the replacement of modules inside the distribution box.

[0008] Optionally, a drive belt is rotatably connected to the outer wall of the driven column at the lower end near the bottom. A transverse groove is provided at the rear end of the power module group. The drive belt rotates inside the transverse groove. Another driven column at the bottom end is rotatably connected to the other end of the drive belt.

[0009] By adopting the above technical solution, the rotating ends on both sides are connected in parallel using a transmission belt, so that both sides rotate upwards at the same time, avoiding incomplete power cut-off caused by uneven force on both sides of the parallel plate.

[0010] Optionally, a connecting block is fixedly connected to the rear end of the power module group near both sides, a clamping block is fixedly connected to the inner side of the connecting block, a stabilizing frame is rotatably connected to the other end of the clamping block, and the other end of the stabilizing frame is located on the outer wall of the retaining ring.

[0011] By adopting the above technical solution, the groove in front of the clamping block is used to allow the tail end of the stabilizer to extend into the groove and rotate. The other end of the stabilizer is attached to the inside of the retaining ring to clamp the worm, thereby increasing its overall stability and preventing the worm from deviating when the drive gear rotates, which would affect the upward pushing of the push end.

[0012] Optionally, clamping plates are fixedly connected to both sides of the clamping block, and the transmission column is rotatably connected to the other end of the clamping plate. The drive gear is attached to the inner side of the bottom end of the clamping plate, and a support block is slidably connected to the outer wall of the driven column. The power module group is fixedly connected to one side of the support block.

[0013] By adopting the above technical solution, while the transmission column drives the drive gear to rotate, the clamping block is used to clamp and position the drive gear, thereby improving the stability of the drive gear rotation.

[0014] Optionally, multiple guide rail grooves are fixedly connected to both sides of the inner cavity of the distribution box shell, and gear guide rails are slidably connected inside the guide rail grooves. The other side of the gear guide rails is fixedly connected to the side of the power module group, and a handle is fixedly connected to the front end of the power module group near the bottom.

[0015] By adopting the above technical solution, when the parallel plate drives the aircraft carrier plug to disengage from the aircraft plug, the gear guide rail slides inside the guide rail groove by pulling the handle, thereby pulling the power module group out of the distribution box shell, expanding the maintenance space and improving maintenance efficiency.

[0016] Optionally, two warning lights are provided at the front end near the top of the power module group, and two support arms are fixedly connected at the rear end near the center of the power module group. A sealing plate is fixedly connected to the top of the support arm, and the top of the sealing plate is parallel to the bottom end of the aircraft carrier.

[0017] By adopting the above technical solution, after the aircraft carrier plug is disconnected from the aircraft connector, the warning light illuminates, ensuring that the power module group is completely de-energized. When the power module group moves outward, the sealing plate behind the power module group moves outward along with the power module group, moving to below the aircraft carrier plug to block the aircraft carrier plug and prevent maintenance personnel from contacting the conductive parts of the aircraft carrier plug, thereby improving the safety of maintenance.

[0018] Optionally, multiple filter screens are fixedly connected to both sides of the inner cavity of the distribution box, and heat dissipation holes are fixedly connected to the outer side of the filter screens.

[0019] By adopting the above technical solution, and utilizing the combination of filter screen and heat dissipation holes, external dust can be effectively prevented from entering the power distribution box and damaging the internal electrical components without affecting heat dissipation inside the distribution box.

[0020] This utility model application has at least the following effects: 1. When a power outage occurs inside the distribution box, the rotating end is turned, which drives the transmission column to rotate. At the same time, the rotation drives the drive gear behind the power module group. The rotation of the drive gear drives the worm gear to rotate, causing the push column at the upper end of the worm gear to move upward and push the parallel plate on the outside of the aircraft carrier plug. This causes the aircraft carrier plug to detach from the aircraft plug and cancel the power supply, achieving a physical disconnection state and completely avoiding the risk of maintenance personnel accidentally touching live parts.

[0021] 2. When the parallel plate drives the aircraft carrier plug to disengage from the aircraft plug, by pulling the handle, the gear guide rail slides inside the guide rail groove, pulling the power module group out of the distribution box shell, moving the power module group from the narrow inside of the distribution box to the outside of the distribution box, expanding the maintenance space and improving maintenance efficiency.

[0022] 3. After the aircraft carrier connector is disconnected from the aircraft plug, the warning light will illuminate to ensure that the power module group is completely de-energized. As the power module group moves outward, the sealing plate behind the power module group will move outward along with the power module group until it is below the aircraft carrier connector, blocking the aircraft carrier connector and preventing maintenance personnel from contacting the conductive parts of the aircraft carrier connector, thereby improving the safety of maintenance.

[0024] The following combination Figure 1 - Figure 5 The present invention will be described in further detail below.

[0025] This embodiment discloses a fast power-off integrated distribution box: including a distribution box shell 1, a cabinet door 11 rotatably connected to one side of the front end of the distribution box shell 1, a power module group 2 provided in the inner cavity of the distribution box shell 1, and a fast power-off component 3 rotatably connected to the front end of the power module group 2.

[0026] See Figures 2 to 4 The fast power-off assembly 3 includes a rotating end 301 rotatably connected to the power module assembly 2. A transmission column 302 is fixedly connected to the other side of the rotating end 301. The transmission column 302 rotates inside both sides of the power module assembly 2. A drive gear 303 is fixedly connected to the outer wall of the other end of the transmission column 302. A worm gear 304 is meshed and rotatably connected to one side of the drive gear 303. Two driven columns 313 are fixedly connected to both ends of the worm gear 304. A retaining ring 307 is fixedly connected to the upper end of the driven column 313. A push end 308 is fixedly connected to the upper end of the retaining ring 307. The power module assembly 2 has multiple aviation plugs 26 at the upper end. An aircraft carrier plug 22 is snapped into the upper end of the aviation plug 26. A parallel plate 23 is fixedly connected to the outer wall of the aircraft carrier plug 22 near the center. The parallel plate 23 is attached to the upper end of the push end 308. The driven column 313 at the lower end is fixedly connected to the parallel plate 23. A transmission belt 311 is rotatably connected near the bottom of the wall. A transverse groove 27 is provided at the rear end of the power module group 2. The transmission belt 311 rotates inside the transverse groove 27. Another driven column 313 at the bottom is rotatably connected inside the other end of the transmission belt 311. A connecting block 309 is fixedly connected near the two sides of the rear end of the power module group 2. A clamping block 310 is fixedly connected inside the connecting block 309. A stabilizing frame 306 is rotatably connected inside the other end of the clamping block 310. The other end of the stabilizing frame 306 is located on the outer wall of the retaining ring 307. A clamping plate 312 is fixedly connected to both sides of the clamping block 310. A transmission column 302 is rotatably connected inside the other end of the clamping plate 312. A drive gear 303 is attached to the inner side of the bottom end of the clamping plate 312. A support block 305 is slidably connected to the outer wall of the driven column 313. A power module group 2 is fixedly connected to one side of the support block 305.

[0027] With this configuration, when a power outage occurs inside the distribution box, turning the rotating end 301 causes the transmission column 302 to rotate. Simultaneously, this rotation drives the drive gear 303 behind the power module group 2. The drive gear 303 rotates, causing the worm gear 304 to rotate. This moves the push column at the upper end of the worm gear 304 upwards, pushing the parallel plate 23 on the outside of the aircraft carrier plug 22. This disconnects the aircraft carrier plug 22 from the aviation connector 26, canceling power transmission and physically disconnecting it. This completely avoids the risk of maintenance personnel accidentally touching live parts, making it particularly suitable for emergency repairs where power is not completely cut off. Simultaneously, the aviation connector 26... This design ensures stable and quick connections between circuits and facilitates the replacement of modules inside the distribution box. Simultaneously, the groove in front of the clamping block 310 allows the tail end of the stabilizer 306 to extend into the groove and rotate. The other end of the stabilizer 306 is attached to the inside of the retaining ring 307, clamping the worm gear 304 and increasing its overall stability. This prevents the worm gear 304 from shifting when the drive gear 303 rotates, thus affecting the upward pushing of the push end 308. Furthermore, the transmission belt 311 connects the rotating ends 301 on both sides in parallel, allowing both sides to rotate upwards simultaneously. This avoids uneven force distribution on both sides of the parallel plate 23, preventing incomplete power disconnection.

[0028] See Figure 1 , Figure 2 and Figure 5 Multiple guide rail grooves 4 are fixedly connected to both sides of the inner cavity of the distribution box shell 1. Gear guide rails 24 are slidably connected inside the guide rail grooves 4. The other side of the gear guide rails 24 is fixedly connected to the side of the power module group 2. A handle 21 is fixedly connected to the front end of the power module group 2 near the bottom. Two warning lights 25 are provided at the front end of the power module group 2 near the top. Two support arms 28 are fixedly connected to the rear end of the power module group 2 near the center. A sealing plate 29 is fixedly connected to the top of the support arm 28. The top of the sealing plate 29 is parallel to the bottom of the aircraft carrier plug 22. Multiple filter screens 12 are fixedly connected to both sides of the inner cavity of the distribution box shell 1. Heat dissipation holes 13 are fixedly connected to the outside of the filter screens 12.

[0029] With this configuration, when the parallel plate 23 causes the aircraft carrier plug 22 to disengage from the aircraft connector 26, pulling the handle 21 causes the gear guide rail 24 to slide inside the guide rail groove 4, pulling the power module group 2 out of the distribution box casing. This moves the power module group 2 from the confined space inside the distribution box to the outside, expanding the maintenance space and improving maintenance efficiency. Simultaneously, after the aircraft carrier plug 22 disengages from the aircraft connector 26, the warning light 25 illuminates, ensuring that the power module group 2 is completely de-energized. As the power module group 2 moves outward, the sealing plate 29 behind it moves outward as well, moving to below the aircraft carrier plug 22 to block it, preventing maintenance personnel from contacting the conductive parts of the aircraft carrier plug 22 and improving maintenance safety.

[0030] The implementation principle of a rapid power-off integrated distribution box according to an embodiment of this application is as follows: When a power outage occurs inside the distribution box due to a fault, the rotating end 301 is turned, which drives the transmission column 302 to rotate. Simultaneously, the rotation drives the drive gear 303 behind the power module group 2. The drive gear 303 rotates, causing the worm gear 304 to rotate. This causes the push column at the upper end of the worm gear 304 to move upwards, pushing the parallel plate 23 on the outside of the aircraft carrier plug 22. This disconnects the aircraft carrier plug 22 from the aircraft connector 26, canceling power transmission and achieving a physical disconnection. Then, by pulling the handle 21, the gear guide rail 24... The grabber slides inside the guide rail groove 4, pulling the power module group 2 out of the distribution box shell. This moves the power module group 2 from the confined space inside the distribution box to the outside, expanding the maintenance space. Simultaneously, after the aircraft carrier plug 22 disengages from the aircraft plug 26, the warning light 25 illuminates, ensuring that the power module group 2 is completely de-energized. As the power module group 2 moves outward, the sealing plate 29 behind it moves outward as well, moving to below the aircraft carrier plug 22 to block it, preventing maintenance personnel from contacting the conductive parts of the aircraft carrier plug 22 and improving maintenance safety.

[0031] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
