Description

Technical Field

[0001] The invention relates to the technical field of control cabinets, and in particular to an intelligent control cabinet for a fluorine chemical process. Background Art

[0002] A fire protection electronic control cabinet is a box or cabinet used to store and protect electronic equipment, controllers, sensors, switches and other components. These control cabinets are usually used in industrial automation, power systems, mechanical equipment and other fields to centrally manage and protect various electronic equipment, ensure their normal operation and provide necessary control functions. Therefore, various electronic equipment will be centrally managed through the control cabinet.

[0003] Fluorine chemical industry is currently a special material production industry in China, and has strict control requirements for the management of the production process. In fluorine chemical production, when sporadic leakage of materials occurs, floating and scattered particles appear, and sparks and arcs appear during the operation of the control cabinet, it is very easy to cause fire accidents, which may cause serious casualties and property losses, and may also cause environmental pollution and other problems. Therefore, the fire-fighting capability of the fluorine chemical process control cabinet is particularly important.

[0004] According to the authorization announcement number: CN113851978B, an intelligent electrical control cabinet is disclosed. By setting a fireproof component, when a fire occurs inside the electrical cabinet, the fire can be extinguished in time, reducing economic losses and improving its safety factor. However, there are still shortcomings. When a fire occurs, the control cabinet extinguishes the fire by letting the fire extinguishing dry powder slide freely on the storage plate, and the angle and position of the storage plate are fixed, resulting in a single landing point for the fallen fire extinguishing dry powder, which cannot be evenly delivered to each unit in the cabinet, resulting in a large difference in the fire extinguishing level of each unit in the cabinet. The fire extinguishing effect of some areas in the cabinet that are delivered with fire extinguishing dry powder is very small, which is not suitable for fluorine chemical scenes with strict fire protection requirements. Therefore, the fire fighting capability of the control cabinet still needs to be improved. Summary of the invention

[0014] As a preferred solution of the present invention, the sensing component includes two smoke sensors fixedly installed on the upper parts of the opposite surfaces of the two side partitions, and an electromagnetic telescopic rod is fixedly installed on the upper parts of the side surfaces away from each other of the two side partitions.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. In the present invention, after the sensing component senses the fire, the limit of the releasing component is released, and the releasing component drives the atomizing component to operate, so that the two traction springs of the delivery component pull the two inverted storage boxes on the left and right to move toward the middle, so that the fire extinguishing dry powder is delivered to the inside of the control cabinet through the delivery holes, and the atomizing component blows the fire extinguishing dry powder delivered to the inside of the control cabinet through the delivery holes obliquely upward through the inclined air distribution cavity to atomize it, so that the fire extinguishing dry powder floating in the control cabinet is dust mist floating, and finally adheres to each unit inside the control cabinet, thereby improving the fire extinguishing effect, and the inclined air distribution cavity gradually decreases in the direction close to the delivery holes, so that the flow rate of the non-combustible gas flowing through the inclined air distribution cavity is accelerated, and the gas pressure becomes larger, which can further improve the blowing intensity of the delivered fire extinguishing dry powder and accelerate the atomization efficiency of the fire extinguishing dry powder.

[0022] When the plurality of air distribution ports are driven by the twisted cylinder to rotate and are staggered with the positions of the plurality of air distribution ports, the air distribution ports and the plurality of air distribution ports are disconnected, and the non-flammable gas inside the corrugated air storage bag will not be connected with the plurality of air distribution ports through the exhaust hole, the exhaust pipe, the universal connector, the torsion tube, the twisted cylinder and the plurality of air distribution ports, resulting in the inability of the corrugated air storage bag to release pressure. Since the corrugated air storage bag cannot release pressure, the left and right inverted storage boxes will be limited, that is, the rebound force of the two front and rear traction springs cannot pull the left and right inverted storage boxes to continue to move toward the middle, resulting in the inverted storage box staying on the top of the control cabinet, which allows the fire extinguishing dry powder inside the inverted storage box to have enough time to be released into the interior of the control cabinet through the release holes under the downward pressure of the pressure spring on the pressure plate.

[0023] 3. In the present invention, by making the air distribution port and the air distribution inclined cavity overlap at intervals, when the twisted cylinder drives the multiple air distribution ports to rotate and stagger the positions of the multiple air distribution inclined cavities, the patterned air storage bag cannot relieve pressure. Since the corrugated air storage bag cannot relieve pressure, the left and right inverted storage boxes will be limited.

[0024] 4. In the present invention, when the slider moves downward along the inner wall of the guide rail, it drives the tensioning slide table and the dynamic friction plate to move downward together. Due to the elastic force of the spring, the tensioning slide table drives the dynamic friction plate to be in close contact with the static friction plate, so that during the downward movement of the slider, the friction between the static friction plate and the dynamic friction plate can avoid the slider from accelerating downward, ensuring that the slider always moves at a uniform speed when moving downward. That is to say, the slider is pulled around the reel by the non-combustible rope at a uniform speed, further ensuring the uniform rotation of the horizontal shaft and the worm, thereby ensuring the uniform rotation of the torsion tube and the twisted cylinder through the meshing action of the worm and the worm wheel, that is to say, the overlapping time of multiple air distribution ports and the air distribution inclined cavity is always a constant interval time, the pressure relief time interval of the corrugated air storage bag is also constant, and the pause time of each movement of the two inverted storage boxes to the middle is also a constant time, thereby ensuring that the amount of fire extinguishing dry powder released during each pause of the inverted storage box is consistent as a whole, and as much as possible ensuring uniform release into the control cabinet.

[0025] 5. In the present invention, through the above-mentioned structures and coordinated control processes, the fire-fighting capability of the control cabinet is greatly improved, and the fire that may occur in the fluorine chemical production can be extinguished in time, which is more suitable for fluorine chemical scenes with strict fire-fighting requirements.

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] See also Figure 1 - Fig. 9 The technical solution provided by the present invention specifically includes the following embodiments:

[0038] Embodiment 1, a fluorine chemical process intelligent control cabinet, comprising a control cabinet 1, wherein two side partitions 101 distributed left and right are fixedly installed inside the control cabinet 1, a plurality of vertically and horizontally distributed delivery holes 102 are opened through the top of the control cabinet 1, and a delivery component is slidably installed on the top of the control cabinet 1, and the delivery component is used for delivering fire extinguishing dry powder;

[0039] The delivery component includes two inverted storage boxes 201 slidably mounted on the top of the control cabinet 1, the two inverted storage boxes 201 are symmetrically distributed on the left and right, and the two inverted storage boxes 201 are located at the top ends of the multiple delivery holes 102, and the inner walls of the two inverted storage boxes 201 are slidably mounted with a pressure plate 202, and at least one pressure spring 203 is fixedly mounted between the top of the pressure plate 202 and the top wall of the inverted storage box 201, and two traction springs 204 distributed front and back are commonly installed between the left and right inverted storage boxes 201;

[0040] Specifically, the two inverted storage boxes 201 on the left and right are pulled toward the middle by the rebound force of the two front and rear traction springs 204. When the inverted storage box 201 moves to the top of the delivery hole 102, the pressure plate 202 moves downward under the rebound force of the pressure spring 203, and compresses the fire extinguishing dry powder stored in the inverted storage box 201 downward, so that the fire extinguishing dry powder is delivered to the inside of the control cabinet 1 through the delivery hole 102. It should be noted that the aperture size of the delivery hole 102 should not be too large to prevent the fire extinguishing dry powder in the inverted storage box 201 from being delivered downward through the delivery holes 102 near the left and right ends at once, so as to ensure that when the two inverted storage boxes 201 move to the middle part, there is still fire extinguishing dry powder left in the inverted storage box 201.

[0041] In the second embodiment, a plurality of atomizing ports 103 distributed vertically are provided through the adjacent side surfaces of the two side partitions 101, and an atomizing component is provided on the top of the control cabinet 1. The atomizing component is located on the top of the plurality of delivery holes 102, and the atomizing component is used for blowing the fire extinguishing dry powder;

[0042] The atomizing component comprises a corrugated air storage bag 301 fixedly installed between two left and right inverted storage boxes 201, two exhaust holes 302 distributed front and back are provided through the middle of the top of the corrugated air storage bag 301, exhaust pipes 303 are fixedly installed on the periphery of the top openings of the two exhaust holes 302, and air distribution seats 305 are fixedly installed on the side away from the two side partitions 101, and a twisted circular groove 306 is provided through the top of the air distribution seat 305 downwardly, and a twisted cylinder 307 is rotatably installed inside the twisted circular groove 306, and a plurality of upper and lower divided air outlets are provided through the outer wall of the twisted cylinder 307. The air distribution port 308 of the air distribution seat 305 is provided with a plurality of inclined air distribution channels 309 distributed up and down on one side near the side partition 101. The plurality of inclined air distribution channels 309 are all connected with the interior of the twisted circular groove 306, and the internal passage of the inclined air distribution channel 309 is gradually reduced toward the end near the side partition 101. A twisting tube 3010 is fixedly installed on the upper part of the inner wall of the twisted cylinder 307, and a universal connector 304 is fixedly installed between the twisting tube 3010 and the exhaust pipe 303, and the twisting tube 3010 is rotatably connected to the exhaust pipe 303 through the universal connector 304;

[0043] The height position of the gas distribution port 308 corresponds to the height position of the gas distribution oblique cavity 309, and the height position of the gas distribution oblique cavity 309 corresponds to the height position of the atomization port 103.

[0044] Specifically, the embodiment uses the rebound force of the two front and rear traction springs 204 to pull the two inverted storage boxes 201 on the left and right to move toward the middle and compress the corrugated air storage bag 301, so that the non-combustible gas stored in the corrugated air storage bag 301 is respectively injected into the interior of the two exhaust pipes 303 through the two exhaust holes 302, and then injected into the interior of the two left and right torsion tubes 3010 through the two exhaust pipes 303 and the two universal connectors 304, and then injected into the interior of the two twisted cylinders 307, and injected into the interior of the multiple gas distribution oblique cavities 309 through the multiple gas distribution ports 308. Due to the inclined setting, the gas passing through the inclined gas distribution cavity 309 will blow obliquely upward through the delivery holes 102 to the fire extinguishing dry powder delivered into the control cabinet 1, so as to atomize it, thereby making the fire extinguishing dry powder floating in the control cabinet 1 float in the form of dust mist, and finally adhere to each unit inside the control cabinet 1, thereby improving the fire extinguishing effect. In addition, the channel of the inclined gas distribution cavity 309 gradually decreases in the direction close to the delivery holes 102, so that the flow rate of the non-flammable gas flowing through the inclined gas distribution cavity 309 is accelerated, and the gas pressure is increased, which can further improve the blowing intensity of the delivered fire extinguishing dry powder and accelerate the atomization efficiency of the fire extinguishing dry powder.

[0045] Furthermore, a dust-proof fine wire mesh is fixedly installed on the inner wall of the atomization port 103. The dust-proof fine wire mesh is arranged inside the atomization port 103 to prevent the fire-extinguishing dry powder dropped into the control cabinet 1 from entering the interior of the inclined air distribution cavity 309 through the atomization port 103. At the same time, the blowing effect of the inclined air distribution cavity 309 can also blow back the fire-extinguishing dry powder attached to the side of the dust-proof fine wire mesh, thereby preventing the dust-proof fine wire mesh from being blocked.

[0046] Furthermore, a top cover 104 is fixedly installed on the top of the control cabinet 1, and the top cover 104 is located outside the two left and right inverted storage boxes 201 and the corrugated air storage bag 301. The top cover 104 is installed to protect the two left and right inverted storage boxes 201 and the corrugated air storage bag 301.

[0047] In the third embodiment, a sensing component is fixedly provided on the upper part of the outer periphery of the side partition 101, and the sensing component is used to sense the fire and limit the position of the atomizing component. A release component is provided on the side faces of the two side partitions 101 away from each other, and the release component is used to drive the atomizing component.

[0048] The sensing component includes two smoke sensors 401 fixedly mounted on the upper parts of the opposite surfaces of the two side partitions 101, and an electromagnetic telescopic rod 402 is fixedly mounted on the upper parts of the side surfaces away from each other of the two side partitions 101. A limited torsion disk 403 is fixedly mounted on the outer wall of the torsion tube 3010, and a limited torsion slot 404 is provided on the outer wall of the limited torsion disk 403. The telescopic end of the electromagnetic telescopic rod 402 is movably clamped in the inner part of the limited torsion slot 404.

[0049] The release component includes two bearing seats 501 fixedly mounted on the upper part of the outer side surface of the side partition 101, the two bearing seats 501 are distributed front and back, and a horizontal shaft 502 is installed inside the two bearing seats 501 for common rotation, a worm 503 is fixedly mounted on the middle of the outer wall of the horizontal shaft 502, a worm wheel 504 is fixedly mounted on the outer wall of the torsion tube 3010, the worm wheel 504 is meshed with the worm 503, winding drums 505 are fixedly mounted on both ends of the outer wall of the horizontal shaft 502, a non-flammable rope 506 is wound around the outer wall of the winding drum 505, and a slider 5014 is fixedly mounted on the bottom of the non-flammable rope 506;

[0050] A guide rail 507 is fixedly installed on the outer side surface of the side partition 101, and the inner wall of the guide rail 507 is slidably connected to the outer wall of the slider 5014. A counterweight 508 is fixedly installed on the side of the slider 5014 away from the side partition 101;

[0051] Specifically, in this embodiment, if a circuit fire occurs inside the control cabinet 1, when any one of the two smoke sensors 401 located on the upper inner wall of the two side partitions 101 senses the generation of smoke, it will immediately transmit a signal to the two electromagnetic telescopic rods 402, and the two electromagnetic telescopic rods 402 are energized to retract their output rods inwardly. The retraction is driven by electromagnetic force and will not be described in detail. The output rods of the two electromagnetic telescopic rods 402 are retracted and withdrawn from the inside of the two torque limiting slots 404, thereby releasing the rotation restriction effect on the two torque limiting disks 403, and then the counterweight 508 generates a downward gravity effect on the slider 5014, driving the slider 5014 to move downward along the inside of the guide rail 507, and the slider 5014 moves downward through the non-flammable rope 506. The winding reel 505 is pulled to rotate, and the rotation of the winding reel 505 further drives the worm 503 to rotate through the transfer effect of the horizontal shaft 502 and the bearing seat 501. Since the worm 503 is meshed with the worm wheel 504, the rotation of the worm 503 drives the torsion tube 3010 and the twisted cylinder 307 to rotate together through the worm wheel 504. The rotation of the twisted cylinder 307 drives multiple gas distribution ports 308 distributed up and down to rotate inside the twisted circular groove 306. When the gas distribution port 308 rotates and overlaps with the gas distribution inclined cavity 309, the interior of the twisted cylinder 307 is connected to the interior of the gas distribution inclined cavity 309 through the gas distribution port 308. At this time, the non-combustible gas stored in the corrugated air storage bag 301 is discharged to the two exhaust pipes 303 through the two exhaust holes 302 respectively. The gas is then injected into the interior of the two left and right torsion tubes 3010 through two exhaust pipes 303 and two universal connectors 304, and then injected into the interior of the two twisted cylinders 307, and injected into the interior of the multiple inclined gas distribution cavities 309 through multiple gas distribution ports 308. The gas is released into the interior of the control cabinet 1 through the inclined gas distribution cavities 309 to blow the fire extinguishing dry powder. When the twisted cylinder 307 drives the multiple gas distribution ports 308 to rotate and stagger the positions of the multiple inclined gas distribution cavities 309, the gas distribution ports 308 and the inclined gas distribution cavities 309 are disconnected, and the non-combustible gas inside the corrugated air storage bag 301 is discharged through the exhaust hole 302, the exhaust pipe 303, the universal connector 304, the torsion tube 3010, the twisted cylinder 307 and the multiple gas distribution cavities. The opening 308 will not be connected to the multiple oblique gas distribution channels 309, resulting in the inability of the corrugated air storage bag 301 to release pressure. Since the corrugated air storage bag 301 cannot release pressure, it will limit the left and right inverted storage boxes 201. In other words, the rebound force of the two front and rear traction springs 204 cannot pull the left and right inverted storage boxes 201 to continue to move toward the middle, causing the inverted storage boxes 201 to stay on the top of the control cabinet 1. This allows the fire extinguishing dry powder inside the inverted storage box 201 to have enough time to be released into the interior of the control cabinet 1 through the release holes 102 under the downward pressure of the pressure spring 203 on the pressure plate 202. As the next air distribution opening 308 overlaps with the oblique gas distribution channel 309, the air distribution opening 308 is connected to the oblique gas distribution channel 309.The corrugated air storage bag 301 continues to release the non-flammable gas, and the two traction springs 204 rebound force continues to pull the two inverted storage boxes 201 on the left and right to move toward the middle, and this cycle continues until the two inverted storage boxes 201 move to the final position, so that the two inverted storage boxes 201 on the left and right will not move to the middle position all at once under the rebound force of the two traction springs 204 in front and behind, avoiding the problem of uneven delivery of fire extinguishing dry powder.

[0052] In the fourth embodiment, a telescopic groove 509 is provided on a side of the slider 5014 away from the counterweight 508, a tensioning slide 5010 is slidably mounted on the inner wall of the telescopic groove 509, two springs 5011 distributed vertically are fixedly mounted between a side of the tensioning slide 5010 close to the counterweight 508 and the inner end surface of the telescopic groove 509, a dynamic friction plate 5012 is fixedly mounted on a side of the tensioning slide 5010 away from the spring 5011, a static friction plate 5013 is fixedly mounted on the inner wall of the guide rail 507 facing the dynamic friction plate 5012, and the surface of the static friction plate 5013 is slidably connected to the surface of the dynamic friction plate 5012;

[0053] Specifically, in this embodiment, when the slider 5014 moves downward along the inner wall of the guide rail 507, the tensioning slide 5010 is driven to move downward together with the dynamic friction plate 5012. Due to the elastic force of the spring 5011, the tensioning slide 5010 drives the dynamic friction plate 5012 to be in close contact with the static friction plate 5013, so that during the downward movement of the slider 5014, the friction between the static friction plate 5013 and the dynamic friction plate 5012 can prevent the slider 5014 from accelerating downward, ensuring that the slider 5014 always moves at a uniform speed when moving downward. In other words, the slider 5014 pulls the winding drum 5012 through the non-flammable rope 506. The rotation speed is always uniform, which further ensures the uniform rotation speed of the horizontal shaft 502 and the worm 503, so that the torsion tube 3010 and the twisted cylinder 307 can rotate at a uniform speed through the meshing action of the worm 503 and the worm wheel 504. In other words, the overlapping time of the plurality of air distribution ports 308 and the air distribution inclined cavity 309 is always a constant interval time, and the pressure relief time interval of the corrugated air storage bag 301 is also constant. The pause time of each time when the two inverted storage boxes 201 move toward the middle is also a constant time, so as to ensure that the amount of fire extinguishing dry powder released during each pause of the inverted storage box 201 is consistent as a whole, and to ensure that the inside of the control cabinet 1 is evenly released as much as possible.

[0054] In the present invention, when an intelligent control cabinet is working, the control cabinet 1 is provided to protect the electrical equipment. If a circuit in the control cabinet 1 catches fire, any one of the two smoke sensors 401 located on the upper inner wall of the two side partitions 101 senses the generation of smoke and immediately transmits a signal to the two electromagnetic telescopic rods 402. The two electromagnetic telescopic rods 402 are energized to retract their output rods inward. The retraction is driven by electromagnetic force and will not be described in detail. The output rods of the two electromagnetic telescopic rods 402 are retracted from the two torque limiting slots 404. The slider 5014 is driven downward along the guide rail 507 by the gravity force generated by the counterweight 508 on the slider 5014. The slider 5014 moves downward and is pulled by the non-flammable rope 506 to rotate the winding drum 505. The rotation of the winding drum 505 is further driven by the transfer effect of the horizontal shaft 502 and the bearing seat 501 to rotate the worm 503. Since the worm 503 is meshed with the worm wheel 504, the rotation of the worm 503 is further driven by the worm wheel 504. The twisting tube 3010 is driven to rotate together with the twisted cylinder 307. The rotation of the twisted cylinder 307 drives the multiple gas distribution ports 308 distributed up and down to rotate inside the twisted circular groove 306. When the gas distribution ports 308 rotate and overlap with the inclined gas distribution cavity 309, the interior of the twisted cylinder 307 is connected with the interior of the inclined gas distribution cavity 309 through the gas distribution ports 308. The rebound force of the two front and rear traction springs 204 pulls the two left and right inverted storage boxes 201 to move toward the middle. When the inverted storage box 201 moves to the top of the delivery hole 102, the pressure plate 202 is pressed against the pressure plate 204. 02 moves downward under the action of the rebound force of the pressure spring 203, compressing the fire extinguishing dry powder stored in the inverted storage box 201 downward, prompting the fire extinguishing dry powder to be released into the control cabinet 1 through the release holes 102. It should be noted that the aperture size of the release holes 102 should not be too large to prevent the fire extinguishing dry powder in the inverted storage box 201 from being released downward through the release holes 102 near the left and right ends at once, ensuring that when the two inverted storage boxes 201 move to the middle part, there is still fire extinguishing dry powder in the inverted storage box 201;

[0055] At the same time, the non-combustible gas stored in the corrugated air storage bag 301 is respectively injected into the two exhaust pipes 303 through the two exhaust holes 302, and then injected into the two left and right torsion tubes 3010 through the two exhaust pipes 303 and the two universal connectors 304, and then injected into the two twisted cylinders 307, and injected into the multiple gas distribution oblique cavities 309 through the multiple gas distribution ports 308. Since the gas distribution oblique cavities 309 are inclined, the gas will pass through the gas distribution oblique cavities 309 obliquely upward. The fine holes 102 blow the fire extinguishing dry powder delivered to the inside of the control cabinet 1 to atomize it, so that the fire extinguishing dry powder floating inside the control cabinet 1 is floating in the form of dust mist, and finally adheres to each unit inside the control cabinet 1, thereby improving the fire extinguishing effect, and the oblique gas distribution channel 309 gradually decreases in the direction close to the delivery fine holes 102, so that the flow rate of the non-combustible gas flowing through the oblique gas distribution channel 309 is accelerated, and the gas pressure becomes larger, which can further improve the blowing intensity of the delivered fire extinguishing dry powder and accelerate the atomization efficiency of the fire extinguishing dry powder;

[0056] When the twisted cylinder 307 drives the multiple air distribution ports 308 to rotate and stagger the positions of the multiple air distribution inclined cavities 309, the air distribution ports 308 and the air distribution inclined cavities 309 are disconnected, and the non-flammable gas inside the corrugated air storage bag 301 will not be connected with the multiple air distribution inclined cavities 309 through the exhaust hole 302, the exhaust pipe 303, the universal connector 304, the torsion tube 3010, the twisted cylinder 307 and the multiple air distribution ports 308, resulting in the corrugated air storage bag 301 being unable to release pressure. Since the corrugated air storage bag 301 is unable to release pressure, the left and right inverted storage boxes 201 will be limited, that is, the rebound force of the two front and rear traction springs 204 cannot pull the left and right inverted storage boxes 201 to continue to move toward the middle, causing the inverted storage boxes 201 to stay on the top of the control cabinet 1. This allows the fire extinguishing dry powder inside the inverted storage box 201 to have enough time to be released into the control cabinet 1 through the release hole 102 under the downward pressure of the pressure spring 203 on the pressure plate 202, and as the next gas distribution port 308 overlaps with the gas distribution oblique cavity 309, the gas distribution port 308 and the gas distribution oblique cavity 309 are connected, the corrugated air storage bag 301 continues to release the non-flammable gas, and the rebound force of the two traction springs 204 continues to pull the two inverted storage boxes 201 on the left and right to move toward the middle, and this cycle continues until the two inverted storage boxes 201 move to the final position, so that the two inverted storage boxes 201 on the left and right will not move to the middle position all at once under the rebound force of the two traction springs 204 in front and behind, thereby avoiding the problem of uneven release of the fire extinguishing dry powder;

[0057] When the slider 5014 moves downward along the inner wall of the guide rail 507, it drives the tensioning slide 5010 and the dynamic friction plate 5012 to move downward together. Due to the elastic force of the spring 5011, the tensioning slide 5010 drives the dynamic friction plate 5012 to be in close contact with the static friction plate 5013, so that during the downward movement of the slider 5014, the friction between the static friction plate 5013 and the dynamic friction plate 5012 can prevent the slider 5014 from accelerating downward, ensuring that the slider 5014 always moves at a uniform speed when moving downward. In other words, the slider 5014 is pulled by the non-flammable rope 506 to rotate around the reel 505. The speed is always uniform, which further ensures the uniform rotation of the horizontal shaft 502 and the worm 503, so that the meshing action of the worm 503 and the worm wheel 504 ensures the uniform rotation of the torsion tube 3010 and the twisted cylinder 307. In other words, the overlapping time of multiple air distribution ports 308 and the inclined air distribution cavity 309 is always a constant interval time, and the pressure relief time interval of the corrugated air storage bag 301 is also constant. The pause time of each movement of the two inverted storage boxes 201 to the middle is also a constant time, thereby ensuring that the amount of fire extinguishing dry powder released during each pause of the inverted storage box 201 is consistent as a whole, and ensuring as much uniform release as possible to the inside of the control cabinet 1.

[0058] The above-mentioned fire extinguishing process can timely and effectively extinguish the fire source in the control cabinet, prevent the fire source from leaking out and causing fire in the harsh environment of fluorine chemical production, ensure the safety and reliability of the fluorine chemical production process, and reduce casualties and property losses. Compared with conventional intelligent electrical control cabinets, the fluorine chemical process intelligent control cabinet of the present invention has high fire-fighting capability and is more suitable for fluorine chemical scenarios with strict fire-fighting requirements.

[0059] While the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the invention.
