Description

Technical Field

[0001] This utility model relates to the field of power distribution cabinet technology, specifically a safety AC power distribution cabinet. Background Technology

[0002] Distribution cabinets are divided into power distribution cabinets, lighting distribution cabinets, and metering cabinets. They are the final-level equipment in a power distribution system. Distribution cabinets are a general term for motor control centers, mainly used in situations where the load is relatively dispersed and there are few circuits. During actual use, improper use of electrical equipment connected to the distribution cabinet or aging of internal wiring can cause fires inside the distribution cabinet. However, in current distribution cabinet usage, when a fire occurs, it requires manual discovery and extinguishing, or the distribution cabinet issues an alarm to remind people to extinguish the fire. Both methods require manual intervention to extinguish the fire, which makes it impossible to extinguish the fire immediately and increases the possibility of the fire spreading. Therefore, we propose a safe AC power distribution cabinet to solve the above problems. Utility Model Content

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Example like Figure 1 , Figure 2 and Figure 3As shown in the figure, an embodiment of the present invention discloses a safety AC power distribution cabinet, including a cabinet body 1. A cabinet door is hinged to the front of the cabinet body 1, and a viewing window is provided on the front of the hinged cabinet door to facilitate external observation of the interior of the cabinet body 1. A box body 2 is fixed to the top of the cabinet body 1, and a box body door is hinged to the front of the box body 2. A T-shaped rod 3 is rotatably connected to the top of the cabinet body 1 via a bearing. Two connecting rods 4 are rotatably connected to the T-shaped rod 3 via pins. Two guide rods 5 are fixed inside the box body 2, and two movable plates 6 are slidably connected to the surfaces of the two guide rods 5. An electric push rod 7 is fixed to the top of the cabinet body 1, and the protruding end of the electric push rod 7 is fixedly connected to one side wall of one of the movable plates 6. A support plate 8 is fixed inside the box body 2, and a fire extinguishing component 9 is provided on the top of the support plate 8. A frame 10 is fixed to the openings on both sides of the cabinet body 1, and a sealing plate component 11 and a dustproof component are provided on each frame 10. 12. A temperature sensor 13 is fixed to the inner wall of the top of the cabinet 1. A battery 14 and a PLC controller 15 are fixed to the top of the support plate 8. The battery 14 is electrically connected to the PLC controller 15. The PLC controller 15 is electrically connected to the electric push rod 7. When this distribution cabinet is used, if spontaneous combustion occurs inside, the temperature sensor 13 will send a signal to the PLC controller 15 after sensing the temperature change inside the cabinet 1. Then, the PLC controller 15 will control the electric push rod 7 to start. At this time, the top end of the electric push rod 7 will push one of the moving plates 6 to move. With the cooperation of the T-shaped rod 3 and the connecting rod 4, the two moving plates 6 can move in opposite directions. After the moving plates 6 move in opposite directions, they will release the restriction on the sealing plate assembly 11. At this time, the sealing plate assembly 11 can seal the frame 10. During the movement of the moving plates 6, the fire extinguishing assembly 9 will be activated, thereby realizing automatic fire extinguishing inside the cabinet 1.

[0015] like Figure 5 As shown, this utility model also includes another method for driving the two movable plates 6 in opposite directions. It mainly includes a transmission rod 16 rotatably connected to the top of the support plate 8 via a bearing. A gear 17 is fixed on the surface of the transmission rod 16, and a drive rack 18 is fixed on one side wall of each of the two movable plates 6. The drive rack 18 is meshed with the gear 17. In use, the transmission rod 16 is driven to rotate by starting the motor. After the transmission rod 16 rotates, it can drive the gear 17 to rotate. After the gear 17 rotates, it can drive the two drive racks 18 to move in opposite directions. Therefore, it is possible to drive the two movable plates 6 to move in opposite directions.

[0016] like Figure 2 , Figure 3 and Figure 4As shown, in some embodiments, the fire extinguishing component 9 includes two carbon dioxide gas cylinders 901 fixed to the top of the support plate 8. Two through holes on the top of the cabinet 1 each have an exhaust pipe 902 fixed inside. One end of each exhaust pipe 902 is connected to the outlet end of the corresponding carbon dioxide gas cylinder 901. A valve 903 is installed on each exhaust pipe 902, and a gear ring 904 is fixed to the surface of each valve 903. A transmission rack 905 is fixed to one side wall of the moving plate 6. The transmission rack 905 meshes with the corresponding gear ring 904. In use, when the moving plate 6 moves, it drives the transmission rack 905 to move. The movement of the transmission rack 905 drives the gear ring 904 to rotate. Simultaneously, the rotation of the gear ring 904 drives the valve 903 to rotate. When the valve 903 opens, the carbon dioxide gas inside the carbon dioxide gas cylinder 901 is sent to the interior of the cabinet 1 through the exhaust pipe 902, thereby reducing the oxygen content inside the cabinet 1 and achieving a fire extinguishing effect.

[0017] like Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments, a slot is provided on the back of the frame 10, and the sealing plate assembly 11 includes a baffle 1101 inserted into the slot of the frame 10. A limit rod 1104 slides inside the through holes opened at the two lugs at the top of the baffle 1101. The bottom ends of the limit rods 1104 are fixedly connected to the frame 10, which can support and guide the baffle 1101. A limit groove is opened on the surface of the baffle 1101, and a limit plate 1102 is slidably connected inside the limit groove. One end of the limit plate 1102 slides through. The cabinet 2 extends into its interior and is fixedly connected to the movable plate 6. Two springs 1103 are fixed to the bottom of the baffle 1101. The bottom ends of the springs 1103 are fixedly connected to the frame 10. In use, when the movable plate 6 moves, it will drive the limiting plate 1102 to move. When the limiting plate 1102 moves, it will release the restriction on the baffle 1101. At this time, under the reset force of the stretched springs 1103, the baffle 1101 will automatically insert and reset into the interior of the frame 10, thereby completing the sealing operation of the cabinet 1.

[0018] like Figure 1 and Figure 3 As shown, in some embodiments, the dustproof component 12 includes a mounting frame 1201 fixed to one side wall of the enclosure 10. A dustproof mesh 1202 is tightly inserted into the slot of the mounting frame 1201. A handle is fixed to one side wall of the dustproof mesh 1202. In use, the dustproof mesh 1202 can block dust and lint, preventing them from entering the interior of the cabinet 1. The dustproof mesh 1202 is inserted and matched with the mounting frame 1201, making it more convenient to remove the dustproof mesh 1202 for cleaning later.

[0019] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
