[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] The utility model provides Figure 1 - Figure 7 The double-sided power distribution control cabinet shown here is convenient for on-site maintenance and includes a control cabinet 1 and electrical components 2. The electrical components 2 are arranged on the inner wall of the control cabinet 1. The control cabinet 1 is mainly used to control, protect and monitor the working status of the controlled electrical equipment. It is a device that assembles switchgear, measuring instruments, protective electrical equipment and auxiliary equipment in a closed or semi-closed metal cabinet or on a screen according to electrical wiring requirements. Its layout should meet the requirements for normal operation of the power system, facilitate maintenance, and not endanger the safety of people and surrounding equipment.

[0024] An observation window 20 is installed on one side of the control cabinet 1 for observing the working conditions of the electrical components 2. Opening and closing doors 3 are rotatably provided on both sides of the inner wall of the control cabinet 1. The two sides can be connected by hinges. The double-door structure allows the operator to open the electrical control cabinet from two different directions, which can provide greater convenience and flexibility when operating, repairing or inspecting the equipment. A handle is fixed on one side of the two opening and closing doors 3 to facilitate the staff to open the closing doors 3 to maintain the electrical components 2 in the control cabinet 1. This is a prior art and will not be elaborated on here.

[0025] The locking mechanism of the two doors 3 is very convenient for maintenance and the maintenance work is very convenient. The two doors 3 are locked at the same time, which simplifies the operation process and allows the doors 3 to be opened freely, thus providing convenience for the maintenance and inspection of the internal equipment of the control cabinet 1. After the maintenance work is completed, the locking device is operated again, and the two doors 3 are locked synchronously. At this time, the air pump 18 is automatically activated to quickly inflate the airbag 16. As the airbag 16 gradually expands, it pushes the sealing ring 17 to the contact groove 13 on the door 3, forming a strong and tight contact interface, thereby significantly enhancing the sealing performance of the door 3 when closed, and ensuring the stability and safety of the internal environment of the control cabinet 1.

[0026] The locking assembly includes a compartment 4, which is fixedly arranged on the inner wall of the control. A rotating rod 5 is rotatably arranged on the inner wall of the compartment 4. A lock core is provided at one end of the rotating rod 5 close to the observation window 20 for inserting the key into the lock core, and a protective cover is also provided on the control cabinet 1 to cover the lock core.

[0027] Specifically, a gear 6 is fixedly provided on the outer wall of the rotating rod 5, and two racks 7 are slidably connected to the inner wall of the compartment 4. The two racks 7 slide with the inner wall of the compartment 4, and the two racks 7 are meshed with the gear 6. A push plate 8 is fixedly provided on the side of the two racks 7 away from the gear 6. When the staff inserts the key into the lock cylinder and rotates it clockwise, the rotating rod 5 can be rotated clockwise to rotate the gear 6, and the rotation of the gear 6 drives the two racks 7 to slide toward the inside of the control cabinet 1.

[0028] Furthermore, a first slide groove 9 is provided on both sides of the inner wall of the control cabinet 1, and a limit block 10 is slidingly provided on the inner wall of the first slide groove 9. The outer wall of the limit block 10 is sleeved with a spring 11, and one end of the spring 11 is fixed to the inner wall of the first slide groove 9. The opening and closing door 3 is provided with a limit groove 12 on both sides close to the first slide groove 9, and the limit block 10 is plugged into the limit groove 12. The side of the limit block 10 close to the push plate 8 is arranged in an arc shape, and the side of the push plate 8 close to the limit block 10 is arranged in an inclined surface. The coordination of the arc and the inclined surface can achieve a smooth transition and contact, reduce the friction and resistance caused by shape mismatch, and make the contact process smoother.

[0029] When the rotating rod 5 rotates clockwise, the rotating rod 5 slides toward the inner side of the control cabinet 1 with the pushing plate 8. As the pushing plate 8 moves, the inclined surface of the pushing plate 8 gradually breaks away from the arc surface of the limit block 10. During this process, the spring 11, which was previously deformed due to pressure, gradually recovers its original shape, thereby driving the limit block 10 to slide out of the limit groove 12 and return to the first slide groove 9. At this time, the plug-in state of the limit block 10 and the limit groove 12 is released, so that the two opening and closing doors 3 complete the unlocking process synchronously;

[0030] When the staff closes the opening and closing door 3, they first close the door body and insert the key into the lock cylinder and rotate it counterclockwise. This operation will drive the rotating rod 5 to rotate counterclockwise, and then drive the gear 6 connected to it to rotate in the same direction. The counterclockwise rotation of the gear 6 will act on the two racks 7 respectively, causing them to slide along the outer direction of the control cabinet 1. During the sliding process, the inclined surface of the sliding plate on the rack 7 will contact the arc-shaped part of the limit block 10, thereby pushing the limit block 10 to slide along the inner wall of the first slide groove 9. This sliding action is accompanied by the compression of the spring 11 until the limit block 10 completely passes through the first slide groove 9 and is plugged into the limit groove 12, thereby achieving a firm locking of the two opening and closing doors 3.

[0031] Furthermore, considering the possible influence of the two opening and closing doors 3 on the sealing performance of the control cabinet 1 when it is used in an outdoor environment, contact grooves 13 are provided on both sides of the opening and closing door 3, and a position sensor 14 is fixedly provided on the inner wall of the limit groove 12. A placement groove 15 is provided on the inner wall of the control cabinet 1, and an air bag 16 is slidingly provided on the inner wall of the placement groove 15. Sealing rings 17 are fixedly provided on both sides of the air bag 16. An air pump 18 is fixedly provided on the inner wall of the control cabinet 1, and the air pump 18 is connected to the air bag 16. One end of the air bag 16 is connected to a solenoid valve 19. When the opening and closing door 3 is locked, After being determined, when the position sensor 14 captures the position of the limit block 10, it responds quickly and activates the air pump 18 to start pumping. Subsequently, the extracted gas is transmitted to the inside of the airbag 16, prompting the airbag 16 to quickly unfold and expand until it completely fills the space of the contact groove 13. As the airbag 16 is filled, the sealing rings 17 on both sides thereof fit tightly and evenly on the inner wall of the contact groove 13. At this time, the air pump 18 automatically turns off and stops supplying air, while the airbag 16 remains in an expanded state, effectively shortening the gap between the opening and closing doors 3 and significantly improving the sealing performance of the control cabinet 1.

[0032] When the staff unlocks the door 3, the position sensor 14 immediately detects that the limit block 10 has left its detection range, triggering the solenoid valve 19 to respond quickly, starting the exhaust program, and the gas in the airbag 16 is quickly discharged, causing the airbag 16 to gradually retract and eventually completely retract into its original placement slot 15.
