[0001] The invention relates to the technical field of power distribution corridor construction, in particular to a cabinet fire extinguishing system based on a perfluorohexanone power distribution corridor. Background Art

[0002] In the power system, distribution corridors and cabinets, as key infrastructure, undertake important tasks of power distribution, transmission and protection. These facilities are usually deployed in complex and changeable environments, including but not limited to industrial plants, commercial buildings, data centers and residential areas, which contain a large number of electrical equipment and lines. Due to electrical failures, short circuits, overloads or external fire sources, there is a risk of fire inside distribution corridors and cabinets. In recent years, perfluorohexanone, as a new type of fire extinguishing agent, has received widespread attention in the fire extinguishing of electrical equipment due to its good electrical insulation, low toxicity, rapid gasification and heat absorption, and no residue after fire extinguishing. The perfluorohexanone fire extinguishing system releases perfluorohexanone gas to quickly reduce the fire temperature and inhibit the combustion chain reaction, thereby achieving the purpose of fire extinguishing.

[0003] When the existing perfluoroacetic acid fire extinguisher is in use, the cabinet cannot form a closed space due to the ventilation holes on the cabinet, so the fire extinguishing performance of perfluoroacetic acid cannot be fully exerted. In addition, due to the space limitation of the cabinet, the perfluoroacetic acid fire extinguisher is generally set at the edge of the cabinet, so that the perfluoroacetic acid cannot be quickly moved to the fire point.

[0034] The fixing seat 201a is used to support the delivery pipe 201b. The delivery pipe 201b transports high-pressure perfluoroacetic acid gas. Through the connection between the through groove 201b-1 and the connecting groove 201c-1, the high-pressure perfluoroacetic acid gas in the delivery pipe 201b can enter the fire extinguishing pipe 201e. There are two fire extinguishing pipes 201e, which are located on the upper and lower sides of the inside of the electrical box 104 respectively, so that the fire extinguishing pipe 201e can better cover the fire point in the electrical box 104.

[0035] Specifically, a jet hole 201e-1 is opened at the top of the fire extinguishing pipe 201e, and a plurality of air outlet holes 201e-2 are opened at one side of the fire extinguishing pipe 201e.

[0042] Specifically, the fire extinguishing assembly 200 also includes a transmission member 203, which is arranged on one side of the sealing member 202, including a positioning block 203a fixed to the top of the fixing frame 202a, a push rod 203b sliding in the positioning block 203a, and a rack 202e fixed in the push rod 203b.

[0043] The positioning block 203a is used to limit the push rod 203b so that the push rod 203b can move stably, thereby driving the rack 202e to move on one side of the rotating gear 202d.

[0044] Specifically, the transmission member 203 further includes a positioning ring 203f fixed to the surface of the push rod 203b, a threaded rod 203g is fixed to the end of the push rod 203b, and a threaded sleeve 203h is rotatably connected to the surface of the threaded rod 203g through threads.

[0045] The threaded sleeve 203h can be rotated to drive the threaded rod 203g to move, so that the threaded rod 203g pushes or pulls the push rod 203b.

[0046] Specifically, the fire extinguishing assembly 200 also includes a driving member 204, which is arranged in the electrical box 104, including a fixed block 204a fixed to the bottom wall of the electrical box 104, a rotating rod 204b is rotatably connected in the fixed block 204a, and a threaded sleeve 203h is fixed to the end of the rotating rod 204b.

[0049] A fixing sleeve 204d is fixed to the inner top wall and the inner bottom wall of the electrical box 104, so that the driving shaft 204e can rotate stably, so that the worm 204f can drive the worm wheel 204c to rotate, so that the worm wheel 204c drives the rotating rod 204b to rotate.

[0050] Example 3, reference Figures 1 to 9 , which is the third embodiment of the present invention, and is based on the first two embodiments.

[0051] Specifically, the driving member 204 also includes a transmission gear 204g fixed to the surface of the driving shaft 204e, a driving motor 204h is fixed in the electrical box 104, a driving gear 204i is fixed to the output end of the driving motor 204h, and a fire detector 204j is fixed to the inner wall of the electrical box 104.

[0052] A control module is provided in the fire detector 204j. When the fire detector 204j detects a fire in the electrical box 104, the drive motor 204h can be started through the control module, so that the drive motor 204h drives the drive gear 204i to rotate, and the drive gear 204i can drive the transmission gear 204g to rotate, thereby driving the drive shaft 204e to rotate.

[0053] Specifically, the fire extinguishing assembly 200 also includes an adjusting member 205, which is arranged in the electrical box 104, including a supporting block 205a fixed to the inner bottom wall of the electrical box 104, a rotating column 205b is rotatably connected inside the supporting block 205a, an adjusting gear 205c is fixed to the rotating column 205b, a supporting plate 205d is fixed to the top of the push rod 203b, an adjusting rack 205e is fixed between the two supporting plates 205d, and the adjusting gear 205c is meshed with the adjusting rack 205e.

[0054] The rotating column 205b is fixed to one side of the limit plate 201d. When the push rod 203b moves, the support plate 205d can drive the adjusting rack 205e to move synchronously, so that the adjusting rack 205e drives the adjusting gear 205c to rotate. When the rack 202e drives the rotating gear 202d to rotate 90 degrees, the adjusting rack 205e also drives the adjusting gear 205c to rotate 90 degrees.

[0055] During use, when the fire detector 204j detects a fire in the electrical box 104, the control module can be used to start the drive motor 204h, so that the drive motor 204h drives the drive gear 204i to rotate, and the drive gear 204i can drive the transmission gear 204g to rotate, thereby driving the drive shaft 204e to rotate, and the drive shaft 204e can drive the worm 204f to rotate, so that the worm 204f can drive the worm wheel 204c to rotate, so that the worm wheel 204c drives the rotating rod 204b to rotate, and the rotating rod 204b can drive the threaded sleeve 203h to rotate, and the threaded sleeve 203h can drive the threaded rod 203g to move, so that the threaded rod 203g pushes the push rod 203b, so that the push rod 203b drives the rotating gear 202d to rotate 90 degrees through the rack 202e, so that the sealing plate 202c rotates from a vertical state to a horizontal state, thereby sealing the vent of the electrical box 104.

[0056] During the movement of the push rod 203b, the support plate 205d can drive the adjusting rack 205e to move synchronously, so that the adjusting rack 205e drives the adjusting gear 205c to rotate, thereby causing the adjusting gear 205c to rotate 90 degrees. At this time, the adjusting gear 205c drives the limit plate 201d to rotate through the transmission of the rotating column 205b, thereby driving the rotating sleeve 201c to rotate 90 degrees, so that the through groove 201b-1 and the connecting groove 201c-1 are connected, so that the high-pressure perfluorohexanone gas in the delivery pipe 201b can enter the fire extinguishing pipe 201e, and the perfluorohexanone can quickly reach the ignition point through the injection hole 201e-1 and the air outlet 201e-2 set on the fire extinguishing pipe 201e, thereby suppressing the spread of the fire, ensuring that the fire extinguishing agent can quickly and evenly cover the fire source, and improving the fire extinguishing efficiency.

[0057] When the fire is extinguished, the driving motor 204h rotates in the opposite direction, causing the sealing plate 202c to change from a horizontal state to a vertical state, thereby allowing the ventilation opening of the electrical box 104 to be ventilated again. At the same time, the fire extinguishing pipe 201e will rotate 90 degrees to become horizontal, which will not affect the staff's operation of the electrical appliances in the electrical box 104.
