Technical Field

[0001] This utility model relates to the field of safety technology for complete sets of power distribution equipment for power grids, and specifically discloses a safe complete set of power distribution equipment for power grids. Background Technology

[0002] With the continuous development of the economy and society, the power grid plays an indispensable role. In order to meet the needs of more groups, staff often set up public power grid power distribution equipment outdoors. Public power grid power distribution equipment includes a protective shell and multiple wires, circuits and electronic devices installed inside the protective shell. Due to the harsh outdoor environment, public power grid power distribution equipment needs to be inspected and maintained frequently. Because there are many public power grid power distribution equipment, and some of them are prone to short circuits and burnout after long-term use, damaging circuits and electrical appliances.

[0003] Existing power distribution equipment for public power grids cannot promptly extinguish short-circuit fires or notify staff to conduct timely inspections and repairs, which can easily lead to significant losses. Therefore, a safer power distribution equipment for public power grids is needed to solve this problem. Utility Model Content

[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0024] Please see Figure 1-6A safe power grid power distribution system includes a cabinet 1 and a cabinet door 2. A container 3 is located at the top of the cabinet 1, containing dry powder fire extinguishing agent. An air pump 4 with an air outlet connected to the container 3 is installed on the upper surface of the cabinet 1. A fire extinguishing assembly is located inside the cabinet 1, including two limiting rods 5 fixedly connected between the left and right end faces inside the cabinet 1. A sliding box 6 is slidably connected to the outer walls of the two limiting rods 5. A hexagonal shaft 7 is rotatably connected between the left and right end faces inside the cabinet 1. A servo motor 8 with its output end fixedly connected to a hexagonal shaft 7 is installed on the left end face of the slide box 6. A sleeve 9 rotatably connected to the hexagonal shaft 7 is slidably connected to the inner wall of the slide box 6. A worm gear 10 is fixedly connected to the outer wall of the sleeve 9. The right end of the hexagonal shaft 7 extends to the outside of the cabinet 1 and is fixedly connected to a roller shaft 19. A cam groove 20 is opened on the outer wall of the roller shaft 19. A slide rod 21 extending to the outside of the cabinet 1 is fixedly connected to the right end face of the slide box 6. A roller 22 is rotatably connected to the outer wall of the slide rod 21 through a coupling. The roller 22 is slidably connected to the cam groove 20.

[0025] Multiple spraying mechanisms are provided on the lower end face of the slide box 6.

[0026] In this embodiment: when a fire occurs inside the cabinet 1, the air pump 4 blows air into the container 3, causing the dry powder extinguishing agent inside the container 3 to be sprayed out from the nozzle 17 for fire extinguishing. The servo motor 8 is activated, which drives the hexagonal shaft 7 to rotate, which in turn drives the sleeve 9 to rotate. The sleeve 9 further drives the worm gear 10 to rotate, which in turn drives multiple rotating shafts 11 to rotate through the worm wheel 12. The rotating shafts 11 further drive the nozzle 17 to perform a cross-shaped swing. When the hexagonal shaft 7 rotates, it further drives the roller shaft 19 to rotate, which in turn drives the slide rod 21 to move back and forth left and right through the cam groove 20 and the roller 22. The slide rod 21 further drives the sliding box 6 to move back and forth left and right along the limit rod 5, which in turn drives the nozzle 17 to move back and forth synchronously when performing the cross-shaped swing, expanding the spray range of the dry powder extinguishing agent without leaving any dead corners, resulting in a good fire extinguishing effect.

[0027] As a technical optimization of this utility model, the spraying mechanism includes two support rods 14 fixedly connected to the lower end face of the slide box 6. A movable frame 15 is rotatably connected between the two support rods 14 via a coupling. A spraying pipe 16 is rotatably connected inside the movable frame 15 via a coupling. A nozzle 17 is provided at the lower end of the spraying pipe 16. A connecting pipe 18 connects the spraying pipe 16 and the holding box 3. A rotating shaft 11 is rotatably connected through the lower end face of the slide box 6. A worm wheel 12 that meshes with a worm gear 10 is fixedly connected to one end of the outer wall of the rotating shaft 11 located inside the slide box 6. An L-shaped rod 13 is fixedly connected to the lower end of the outer wall of the rotating shaft 11. The upper end of the spraying pipe 16 is rotatably connected to the L-shaped rod 13 via a coupling.

[0028] In this embodiment: when the worm gear 10 rotates, it drives the worm wheel 12 to rotate, which in turn drives the rotating shaft 11 to rotate. The rotating shaft 11 further drives the L-shaped rod 13 to rotate, which in turn drives the spray pipe 16 and the nozzle 17 to swing in a cross shape through the connecting shaft, the movable frame 15 and the support rod 14. The cross swing of the nozzle 17 expands the spray range of the dry powder extinguishing agent and leaves no dead corners.

[0029] As a technical optimization of this utility model, a smoke sensor 23 and an alarm 24 are provided on the lower end face of the container 3.

[0030] In this embodiment: the smoke sensor 23 facilitates the monitoring of fire conditions inside the cabinet 1. When a fire is detected, the smoke sensor 23 transmits a signal to the controller, which then starts the air pump 4 and the servo motor 8 to extinguish the fire. At the same time, it controls the alarm 24 to issue an audible and visual alarm and sends a signal to the control room.

[0031] As a technical optimization of this utility model, a protective box is provided on the right end face of the cabinet 1, located outside the roller 19 and the slide bar 21.

[0032] In this embodiment: the protective box facilitates the protection of moving parts, preventing mechanical injury to operators.

[0033] As a technical optimization of this utility model, the outer wall of the holding box 3 is provided with a sealing door.

[0034] In this embodiment: opening the sealed door facilitates the addition of dry powder extinguishing agent.

[0035] As a technical optimization of this utility model, a controller is provided on the outer wall of the cabinet door 2, and the air pump 4, servo motor 8, smoke sensor 23 and alarm 24 are all electrically connected to the controller.

[0036] In this embodiment, the controller facilitates signal processing and controls the normal operation of the air pump 4, servo motor 8, and alarm 24.

[0037] The working principle and usage process of this utility model are as follows: When a fire occurs inside the cabinet 1, the air pump 4 blows air into the holding box 3, causing the dry powder extinguishing agent in the holding box 3 to be sprayed out from the nozzle 17 for fire extinguishing. The servo motor 8 is started, and the servo motor 8 drives the hexagonal shaft 7 to rotate, which in turn drives the sleeve 9 to rotate. The sleeve 9 further drives the worm gear 10 to rotate, which in turn drives multiple rotating shafts 11 to rotate through the worm wheel 12. The rotating shafts 11 further drive the L-shaped rod 13 to rotate, which in turn drives the spray pipe 16 and the nozzle 17 to swing in a cross shape through the connecting shaft, movable frame 15 and support rod 14. When the hexagonal shaft 7 rotates, it further drives the roller shaft 19 to rotate, which in turn drives the slide rod 21 to move back and forth left and right through the cam groove 20 and roller 22. The slide rod 21 further drives the sliding box 6 to move back and forth left and right along the limit rod 5, which in turn drives the nozzle 17 to move back and forth synchronously when swinging in a cross shape, expanding the spray range of the dry powder extinguishing agent without leaving any dead corners, and achieving good fire extinguishing effect.
