The extrusion mechanism 3 is used to expel the powder from the powder release mechanism 2. The cabinet 1 is connected to the dispersion and purging mechanism 4, which is used to disperse and release the fire extinguishing powder. After the dispersion and purging mechanism 4 is activated, it purifies the powder released by the powder release mechanism 2, so that the powder covers the electrical components inside the cabinet 1, providing fire extinguishing protection for the electrical components, and at the same time protecting the electrical components that are not burning. For protection, a gas treatment mechanism 5 is connected to the cabinet 1 to process the gas entering the dispersion purging mechanism 4.

[0043] Reference Figure 3The powder release mechanism 2 includes a housing 21, a metal pipe 22, and a solenoid valve 23. The housing 21 is fixedly connected to the upper end of the cabinet 1. The upper end of the housing 21 is connected to the extrusion mechanism 3. The housing 21 is used to hold fire extinguishing powder. One end of the metal pipe 22 is connected to the bottom end of the housing 21. The metal pipe is used to discharge the fire extinguishing powder in the housing 21. The other end of the metal pipe 22 extends into the cabinet 1. The outlet of the other end of the metal pipe 22 is set towards the dispersion and purging mechanism 4. The solenoid valve 23 is connected to the metal pipe 22. The solenoid valve 23 is used to control the conduction of the metal pipe 22. The solenoid valve 23 is connected to the controller through a wire. After the solenoid valve 23 is opened, the powder in the housing 21 is released from the metal pipe 22.

[0044] Reference Figure 3 The extrusion mechanism 3 includes a motor 31, a first rotating shaft 32, and an extrusion component 33. The motor 31 is fixedly connected to the upper end of the housing 21 and is connected to the controller via a wire.

The other end of the first rotating shaft 32 extends into the housing 21 and is fixedly connected to the extrusion component 33. The extrusion component 33 is used to extrude the powder in the housing 21 into the metal tube 22. The controller controls the motor 31 to be powered on and started. After the motor 31 starts, it drives the first rotating shaft 32 to rotate. The first rotating shaft 32 drives the extrusion component 33 to rotate. After the extrusion component 33 rotates, it extrudes the fire extinguishing powder in the housing 21 into the metal tube 22.

[0045] Reference Figure 5 The dispersed purging mechanism 4 includes a first transmission assembly 41, fan blades 42, and an open box 43, wherein:

[0046] The open box 43 is connected to the cabinet 1. The fan blade 42 is rotatably connected to the open box 43. The fan blade 42 is connected to the first rotating shaft 32 through the first transmission assembly 41. The first rotating shaft 32 drives the fan blade 42 through the first transmission assembly 41. After the fan blade 42 rotates, it generates wind. The generated wind blows away the powder released from the metal pipe 22. The flying powder falls on the electrical components inside the cabinet 1, extinguishing the fire on the electrical components and protecting the electrical components that have not burned.

[0047] The first transmission assembly 41 includes a second rotating shaft 411, a first gear 412, a second gear 413, and a first belt drive 414. The second rotating shaft 411 is rotatably connected to the open box 43. The second rotating shaft 411 is connected to the first rotating shaft 32 through the first belt drive 414. The first gear 412 is fixedly connected to the fan blade 42. The second gear 413 is fixedly connected to the second rotating shaft 411. The second gear 413 meshes with the first gear 412. The first rotating shaft 32 drives the second rotating shaft 411 to rotate through the first belt drive 414. The second rotating shaft 411 drives the first gear 412 to rotate through the second gear 413. The first gear 412 drives the fan blade 42 to rotate. Through the tooth matching between the first gear 412 and the second gear 413, the rotation speed of the fan blade 42 is greater than the rotation speed of the first rotating shaft 32, and wind power is generated after the fan blade 42 rotates rapidly.

[0048] Reference Figure 3 The protective mechanism 6 includes a support rod 61 and a baffle 62. One end of the support rod 61 is fixedly connected to the upper end of the cabinet 1. The support rod 61 is used to support and fix the baffle 62. The other end of the support rod 61 is fixedly connected to the baffle 62. The baffle 62 is used to shield rainwater and dust.

[0049] Working process: When the smoke sensor detects smoke in cabinet 1, the controller controls the solenoid valve 23 to open, and the controller controls the motor 31 to start. After the motor 31 starts, it drives the first rotating shaft 32 to rotate. The first rotating shaft 32 drives the extrusion component 33 to rotate. After the extrusion component 33 rotates, it squeezes the fire extinguishing powder in the cabinet 21 into the metal tube 22. The powder in the metal tube 22 is released from the outlet. At the same time, the first rotating shaft 32 also drives the second rotating shaft 411 to rotate through the first belt drive component 414. The second rotating shaft 411 drives the first gear 412 to rotate through the second gear 413. The first gear 412 drives the fan blade 42 to rotate. The tooth engagement between the fan blade 42 and the second gear 413 allows the fan blade 42 to rotate at a speed greater than that of the first shaft 32. After the fan blade 42 rotates rapidly, the external gas is processed by the gas handling mechanism 5 and then enters the open box 43. The gas is accelerated by the fan blade 42 and generates wind. The powder released from the outlet of the metal pipe 22 falls into the open box 43. The wind generated by the fan blade 42 blows away the falling powder. The blown powder disperses and covers the electrical components, extinguishing the fire. At the same time, the unburned components are covered by the powder, which isolates the electrical components, preventing the flame from burning them and protecting the unburned electrical components.

[0050] This invention also proposes a control method for an electrical control cabinet, comprising the following steps:

[0051] S1: When the smoke sensor detects smoke in cabinet 1, the controller controls the solenoid valve 23 to open and the controller controls the motor 31 to start. After the motor 31 starts, it drives the first rotating shaft 32 to rotate. The first rotating shaft 32 drives the extrusion component 33 to rotate. After the extrusion component 33 rotates, it squeezes the fire extinguishing powder in cabinet 21 into metal pipe 22. The powder in metal pipe 22 is released from the outlet.

[0052] S2: At the same time, the first rotating shaft 32 also drives the second rotating shaft 411 to rotate through the first belt drive 414. The second rotating shaft 411 drives the first gear 412 to rotate through the second gear 413. The first gear 412 drives the fan blade 42 to rotate. Through the tooth matching between the first gear 412 and the second gear 413, the rotation speed of the fan blade 42 is greater than the rotation speed of the first rotating shaft 32.

[0053] S3: After the fan blade 42 rotates rapidly, the external gas is processed by the gas handling mechanism 5 and then enters the open box 43. The gas is accelerated by the fan blade 42 and generates wind. The powder released from the metal pipe 22 outlet falls into the open box 43. The wind generated by the fan blade 42 blows away the falling powder. The blown powder disperses and covers the electrical components, extinguishing the fire on the electrical components. At the same time, the unburned components are covered by the powder, which isolates the electrical components, so that the flame will not burn the electrical components, thus protecting the unburned electrical components.

[0054] S4: After the fan blade 42 rotates, the gas processing mechanism 5 dries the gas. The gas processing process is that the external gas enters the processing box 51 through the air inlet 53. The gas in the processing box 51 comes into contact with the drying component 54. The drying component 54 dries the gas. After drying, the gas is dispersed through the perforated plate 52 and enters the open box 43.

[0055] S5: When the fan blade 42 rotates to blow away the powder, the recovery mechanism 7 recovers and reuses the powder. The powder recovery process is that a portion of the powder blown away falls into the collection box 711, which collects the powder. The gas in the collection box 711 is released from the venting mesh 713. The first rotating shaft 32 drives the third rotating shaft 731 to rotate through the second belt drive component 732. The third rotating shaft 731 drives the threaded feeding component 722 to rotate. With the cooperation of the housing 721, the threaded feeding component 722 extracts the powder in the collection box 711. The extracted powder is introduced into the box 21 through the discharge pipe 723 for reuse, reducing powder waste.

[0056] Example 2

[0057] When the powder is dispersed by the fan blades 42, external gas enters the open box 43. If the gas entering the open box 43 is humid, the humid gas will condense into water droplets on the electrical components. These water droplets can easily damage the electrical components. (Refer to...) Figure 1-4 As another preferred embodiment of the present invention, the difference from Embodiment 1 is that the gas processing mechanism 5 includes a processing box 51, a perforated plate 52, an air inlet 53, and a drying assembly 54, wherein:

The perforated plate 52 is used to disperse the gas into the open box 43. The perforated plate 52 is connected to the open box 43. The air inlet 53 is opened on the processing box 51 to facilitate the entry of external gas into the processing box 51. The processing box 51 is connected to a drying component 54 for drying the gas. The drying component 54 is used to dry the gas entering the processing box 51. After the fan blade 42 rotates, suction is generated in the processing box 51. External gas enters the processing box 51 through the air inlet 53. The gas in the processing box 51 comes into contact with the drying component 54. The drying component 54 dries the gas. After drying, the gas is dispersed through the perforated plate 52 and enters the open box 43.

[0059] The drying assembly 54 includes a mesh cover 541 and a dehumidifying packing layer 542. The mesh cover 541 is fixedly connected to the processing box 51.

The dehumidifying packing layer 542 is a silica gel water-absorbing particle packing layer.

[0060] Example 3

[0061] When the powder is dispersed by the rotation of the fan blade 42, some of the powder accumulates on the side away from the fan blade 42, and the powder accumulates at the bottom of the cabinet 1, resulting in some powder waste. (Refer to...) Figure 4-5 As another preferred embodiment of the present invention, based on embodiment 1, it further includes a recycling mechanism 7 for recycling powder. The recycling mechanism 7 includes a collection component 71, a return component 72, and a second transmission component 73, wherein:

The return component 72 is connected to the box 21 and is connected to the first rotating shaft 32 through the second transmission component 73. When the fan blade 42 rotates to blow away the powder, a portion of the powder blown away falls into the collection component 71. The collection component 71 collects the powder. The first rotating shaft 32 drives the return component 72 to work through the second transmission component 73. After the return component 72 works, it guides the powder in the collection component 71 into the box 21 for reuse, reducing powder waste.

[0063] The collection component 71 includes a collection box 711, an opening 712, and a venting mesh 713.

[0064] The return assembly 72 includes a housing 721, a threaded feeder 722, and a discharge pipe 723. The housing 721 is connected to the collection box 711 and passes through a ventilated mesh 713. The threaded feeder 722 is disposed inside the housing 721 and is used to extract powder from the collection box 711. The threaded feeder 722 cooperates with the housing 721 and is connected to the first rotating shaft 32 through a second transmission assembly 73. One end of the discharge pipe 723 is connected to the housing 721 and is used to guide the extracted powder into the box 21. The other end of the discharge pipe 723 is connected to the box 21. The second transmission assembly 73 drives the threaded feeder 722 to rotate. After the threaded feeder 722 rotates, it extracts the powder from the collection box 711, and the extracted powder is guided into the box 21 through the discharge pipe 723.

[0065] The second transmission assembly 73 includes a third rotating shaft 731 and a second belt drive 732. The third rotating shaft 731 is rotatably connected to the housing 721. The third rotating shaft 731 is fixedly connected to the threaded feeding component 722. The third rotating shaft 731 is connected to the first rotating shaft 32 through the second belt drive 732. The first rotating shaft 32 drives the third rotating shaft 731 to rotate through the second belt drive 732. The third rotating shaft 731 drives the threaded feeding component 722 to rotate, thereby driving the return assembly 72 to extract the powder from the collection box 711.

[0066] Working process: When the fan blade 42 rotates to blow away the powder, a portion of the powder falls into the collection box 711. The collection box 711 collects the powder, and the gas inside the collection box 711 is released from the venting mesh 713. The first rotating shaft 32 drives the third rotating shaft 731 to rotate via the second belt drive component 732. The third rotating shaft 731 drives the threaded feed component 722 to rotate. With the cooperation of the housing 721, the threaded feed component 722 extracts the powder from the collection box 711. The extracted powder is introduced into the box body 21 through the discharge pipe 723 for reuse, reducing powder waste.
