[0002] The main function of the distribution cabinet is to distribute the electric power from the power grid or generator to each circuit and device in a building or facility. It realizes the branching and distribution of electric power through the internal circuit breakers and cable connections. Circuit breakers and protection devices are installed inside the distribution cabinet to protect each circuit and related devices from overload, short circuit and other electrical faults. The circuit breaker will automatically disconnect the circuit when the current is abnormal (such as overload), preventing equipment damage or fire. The distribution cabinet allows operators to manually control the on-off state of each circuit. By manually operating the switch or circuit breaker, independent control of the circuit can be achieved for maintenance, repair or temporary power-off.

For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0045] As Figures 1-4 shown, a high-efficiency and environmentally friendly automatic fire extinguishing low-voltage power distribution cabinet includes: a box body 1, a layered plate 2, an outer shell 3, a lifting and turning mechanism 4, a lifting pipe 5, a nozzle 6, a connecting piece 7, a cylinder 8, a fire protection shell 9, a gas fire extinguisher 10, a connecting pipe 11, and an output hose 12. The layered plate 2 is arranged inside the box body 1. The layered plate 2 divides the box body 1 into upper and lower two-layer spaces. The design intention of the layered plate 2 is to divide the internal space of the power distribution cabinet into upper and lower two layers, so as to effectively isolate smoke and flames in case of a fire, and at the same time provide necessary space for fire extinguishing operations. The outer shell 3 is installed on the top of the box body 1. The lifting and turning mechanism 4 is installed inside the outer shell 3. The design of the lifting and turning mechanism 4 allows the lifting pipe 5 to rotate in case of a fire, so that the nozzle 6 can cover the combustion area in all directions, improving the fire extinguishing efficiency. The bottom end of the lifting pipe 5 passes through the outer shell 3. Strip-shaped protrusions are arranged on the pipe body of the lifting pipe 5. A through hole 17 is opened on the layered plate 2. The through hole 17 is located in the extending direction of the bottom end of the lifting pipe 5. The nozzle 6 is installed at the bottom end of the lifting pipe 5. One end of the connecting piece 7 is connected to the top of the lifting pipe 5. The output end of the cylinder 8 is connected to the other end of the connecting piece 7. The functions of the connecting piece 7 and the cylinder 8 are to control the lifting movement of the lifting pipe 5, ensuring that the nozzle 6 can adjust its position according to needs, so as to extinguish fires in different hierarchical spaces.

[0046] The fire protection shell 9 is located on one side of the box body 1. At least two gas fire extinguishers 10 are installed side by side inside the fire protection shell 9. The pipe body of the connecting pipe 11 is communicated with the output nozzles of the two gas fire extinguishers 10. One end of the output hose 12 is connected to the connecting pipe 11. The other end of the output hose 12 is connected to the top end of the lifting pipe 5.

[0047] In this embodiment, as Figure 4As shown, the lifting and steering mechanism 4 includes a first base 41 installed inside the outer housing 3, a steering gear 42 installed on the top of the first base 41, and the steering gear 42 is sleeved on the body of the lifting pipe 5. A second base 43 is located on one side of the first base 41. A main gear 44 is installed on the second base 43. A motor 45 is installed on the top of the outer housing 3, and the output end of the motor 45 passes through the outer housing 3 and is connected to the main gear 44. One end of a belt 46 is sleeved on the steering gear 42, and the other end of the belt 46 is sleeved on the main gear 44. Through the steering gear 42 and the belt 46 system driven by the motor 45, the rotation control of the lifting pipe 5 is realized, so that the nozzle 6 can spray the fire extinguishing agent.

[0048] Preferably, the circuit breaker 13 is installed in the upper space inside the box body 1. The combination of the circuit breaker 13 and the detector 14 is used to cut off the power supply when a fire is detected, preventing electrical equipment from continuing to heat up or causing sparks, thereby exacerbating the fire. The detector 14 is arranged on one side of the circuit breaker 13 and is electrically connected to the circuit breaker 13. For the power distribution cabinets on the upper and lower floors, a comprehensive detector can be selected to cover the two floors of space. This detector detects through smoke, temperature and flame to improve the accuracy and reliability of detection so as to detect a fire on the upper or lower floor in time. The controller 15 is installed on one side outside the box body 1. The controller 15 is electrically connected to the detector 14, the motor 45 is electrically connected to the controller 15, and the cylinder 8 is electrically connected to the controller 15. The solenoid valve 16 is installed at the connection of the output hose 12 and the connecting pipe 11. The solenoid valve 16 is electrically connected to the controller 15, and the controller 15 is responsible for receiving the signal of the detector 14 and commanding the start of the fire extinguishing system. The solenoid valve 16 is designed to be opened or closed under the control of the controller 15 to allow the flow of the fire extinguishing agent.

[0049] It should be noted that the present utility model is an energy-efficient and environmentally friendly automatic fire extinguishing low-voltage power distribution cabinet. When in use, when a fire breaks out in the upper layer of the cabinet body 1, the flame detector 14 will send an instruction to the circuit breaker 13, and the circuit breaker 13 will immediately cut off the power supply of the distribution box to prevent the fire from deteriorating further. After that, the flame detector 14 will simultaneously activate the controller 15. The controller 15 receives the instruction and first activates the solenoid valve 16, enabling the gas fire extinguisher 10 to enter the connecting pipe 11. The inert gas will flow along the connecting pipe 11 into the output hose 12, and then enter the lifting pipe 5 through the output hose 12. After that, it will be ejected from the nozzle 6 to start extinguishing the fire. Then, the controller 15 sends an instruction to start the motor 45. The output end of the motor 45 rotates, driving the main gear 44. The main gear 44 drives the belt 46, and then the belt 46 drives the steering gear 42 to rotate. The rotation of the steering gear 42 drives the lifting pipe 5 to rotate. After the lifting pipe 5 rotates, it will drive the nozzle 6 at its bottom end to shake its head and spray gas to extinguish the fire. Since the flame detector 14 is a comprehensive detector 14, if a fire breaks out in the lower layer of the cabinet body 1, the flame detector 14 will feedback to the controller 15 in the first time. The controller 15 will then send an instruction to start the cylinder 8. The cylinder 8 will press down the output end. The output end will be pressed down, and the pressed-down output end will drive the connecting piece 7. The downward pressure of the connecting piece 7 will drive the lifting pipe 5 to slide downward. The nozzle 6 at the bottom end of the lifting pipe 5 will pass through the through hole 17 and enter the next layer of space to carry out the fire extinguishing operation.
