[0038] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0039] See also Figures 1 to 9 An integrated explosion-proof analysis cabin comprises an explosion-proof cabin body 1, an explosion-proof door 2 is connected to the front side of the explosion-proof cabin body 1, a top plate 3 is fixedly connected to the top of the explosion-proof cabin body 1, and a fire extinguishing component 4 for quickly extinguishing fires of equipment inside the cabin is connected to the lower surface of the top plate 3.

[0040] like Figure 2 - Figure 4 As shown, the fire extinguishing assembly 4 includes an L-shaped plate 41 fixed on the lower surface of the top plate 3, the inside of the L-shaped plate 41 is slidably connected to a slide rod 42, the outer surface of the slide rod 42 is sleeved with a spring 413, the bottom of the slide rod 42 is fixedly connected to a first dry powder storage box 43, the lower surface of the first dry powder storage box 43 is hinged with box doors 46 on both sides, the bottoms of the two box doors 46 are respectively fixedly connected to a storage box 47 and a threaded rod 48, the outer surface of the threaded rod 48 is threadedly connected to a nut 49, the inner surface of the storage box 47 is rotatably connected to a winding shaft 411, the outer surface of the winding shaft 411 is wrapped with a thin rope 410, and a through hole 412 is opened on one side of the storage box 47.

[0041] One side of the winding shaft 411 passes through the interior of the through hole 412 and is wound around the outside of the threaded rod 48. The top of the sliding rod 42 is fixedly connected to a limiting plate. The spring 413 is located between the limiting plate and the L-shaped plate 41. An auxiliary fire extinguishing assembly 44 is connected to the inner surface of the explosion-proof cabin main body 1 near the top plate 3. A jet assembly 45 for fire extinguishing is connected to the top of the top plate 3. A convection assembly 5 for accelerating air flow is connected to one side of the inner surface of the explosion-proof cabin main body 1.

[0042] Pull the string 410 out of the storage box 47, and wrap one end of the string 410 around the surface of the threaded rod 48, turn the nut 49, and press the string 410 wrapped around the threaded rod 48 to prevent the string 410 from loosening on the surface of the threaded rod 48. The string 410 fixes the two doors 46 to prevent the doors 46 from unfolding. Then add fire-extinguishing dry powder to the first dry powder storage box 43. When a fire occurs in the equipment inside the explosion-proof room, since the first dry powder storage box 43 is located just above the inside of the explosion-proof room main body 1, Position, at this time, the thin rope 410 will be melted by the high temperature, causing the thin rope 410 exposed to the outside to melt, and the two box doors 46 will lose the restraint of the thin rope 410, rotate and unfold around the hinge, so that the dry powder inside the first dry powder storage box 43 will quickly fall, and the equipment with fire source inside the explosion-proof room main body 1 can be quickly extinguished, so that the flame can be extinguished at the very beginning of the fire, and the fire can be contained at the source in time, and at the same time, it can avoid the staff failing to discover the fire in time, causing the fire to spread.

[0043] like Figure 5 As shown, the auxiliary fire extinguishing assembly 44 includes a second dry powder storage box 441 fixed on the inner surface of the explosion-proof cabin body 1 and two first servo motor switches 445 fixed on the lower surface of the top plate 3, a sealing plate 442 is hinged at the edge of the bottom of the second dry powder storage box 441, a first servo motor 443 is fixedly connected to one side of the second dry powder storage box 441, a baffle 444 is fixedly connected to the output end of the first servo motor 443, and the first servo motor switch 445 is connected to the first servo motor 443 through a wire.

[0044] The cross section of the second dry powder storage box 441 is trapezoidal. The opening below the second dry powder storage box 441 is shielded by a sealing plate 442 . The baffle 444 is located below the sealing plate 442 . The first servo motor switch 445 is located above the slide bar 42 .

[0045] When the equipment inside the explosion-proof room body 1 explodes and burns, the equipment on the four walls of the explosion-proof room body 1 will also catch fire due to the explosion, and the first dry powder storage box 43 can only extinguish the equipment on the ground inside the explosion-proof room body 1. Therefore, after all the dry powder inside the first dry powder storage box 43 is poured out, the weight of the first dry powder storage box 43 itself drops rapidly. At this time, under the elastic force of the two springs 413, the slide bar 42 and the first dry powder storage box 43 are pushed upward, and the slide bar 42 moves upward to squeeze the first servo motor switch 445, turning the first servo motor switch 445 on. Start, at this time, the first servo motor 443 is energized to work, driving the baffle 444 to rotate, the baffle 444 moves away from under the sealing plate 442, the sealing plate 442 loses the support of the baffle 444, the sealing plate 442 rotates around the hinge, and moves away from the outlet of the second dry powder storage box 441, and the dry powder inside the second dry powder storage box 441 extinguishes the equipment on the inner wall of the explosion-proof room body 1 through the outlet, and quickly extinguishes the equipment installed on the side wall of the explosion-proof room body 1, thereby preventing the first dry powder storage box 43 from being unable to extinguish the equipment on the side wall of the explosion-proof room body 1 and delaying the best time for extinguishing the fire.

[0046] like Figure 6 As shown, the jet assembly 45 includes a carbon dioxide storage box 451 fixed on the upper surface of the top plate 3 and two air pumps 453. The inner surface of the carbon dioxide storage box 451 is fixedly connected to a limiting sleeve 458. The limiting sleeve 458 is internally slidably connected to a limiting rod 457. The bottom of the limiting rod 457 is fixedly connected to a piston plate 452. The output end and input end of the air pump 453 are respectively fixedly connected to a second connecting pipe 456 and a first connecting pipe 455. One end of the two second connecting pipes 456 is connected to a rectangular air distribution pipe 454.

[0047] The rectangular air distribution duct 454 is located inside the explosion-proof cabin body 1 and is fixedly connected to each other on one side of the second dry powder storage box 441. An air inlet is set on the outer surface of the carbon dioxide storage box 451, and one side of the first connecting pipe 455 extends to the interior of the carbon dioxide storage box 451.

[0048] When the dry powder inside the second dry powder storage box 441 can extinguish the equipment on the side wall of the explosion-proof hut main body 1, there may not be enough dry powder at the fire source, resulting in the reignition of the flame. At this time, turn on the two air pumps 453. The air pumps 453 transport the carbon dioxide inside the carbon dioxide storage box 451 to the inside of the rectangular air distribution pipeline 454 through the second connecting pipe 456 and spray it out through the rectangular air distribution pipeline 454, forming a carbon dioxide air curtain below the rectangular air distribution pipeline 454. At this time, a space is formed between the air curtain and the side wall of the explosion-proof hut main body 1. The air curtain formed by carbon dioxide can isolate the equipment from the outside world, so that the flame loses the supply of oxygen and thus achieves the purpose of extinguishing the fire. At the same time, continuously supplying carbon dioxide to the inside of the explosion-proof hut main body 1 can accelerate the dilution of oxygen inside the explosion-proof hut main body 1, thereby further improving the fire extinguishing effect.

[0049] As Figure 7 shown, the convection assembly 5 includes two mounting plates 51 fixed on one side of the inner surface of the explosion-proof hut main body 1 and an arc-shaped rack 53 fixed on the same side as the mounting plates 51. A rotating plate 55 is rotatably connected to one side of the two mounting plates 51 close to each other. A second servo motor 56 is fixedly connected to one side of the mounting plate 51. The upper surface and the lower surface of the rotating plate 55 are rotatably connected with a U-shaped plate 58. A connecting shaft 57 is fixedly installed at the top of the U-shaped plate 58. A gear 54 is fixedly connected to the top of the connecting shaft 57. Two air blowers 52 are fixedly connected to the front side of the U-shaped plate 58. The gear 54 and the arc-shaped rack 53 are meshed with each other.

[0050] The output end of the second servo motor 56 is fixedly connected to one side of the rotating plate 55. Sealing assemblies 59 are connected to both sides of the explosion-proof hut main body 1. Protective nets are arranged on both sides of the air blowers 52. The arc-shaped rack 53 is located between the two mounting plates 51 on both sides.

[0051] When detecting gas inside the explosion-proof hut main body 1, there may be leakage of some flammable gases. The flammable gases remain inside the explosion-proof hut main body 1 and cannot be discharged in time. The flammable gases gather at a certain position. When reaching a certain concentration, they will be ignited by static electricity, thus increasing the possibility of explosion inside the explosion-proof hut main body 1. Generally, the explosion-proof hut main body 1 is provided with ventilation ducts, but the air flow rate inside the explosion-proof hut main body 1 is slow, and it takes a long time to discharge the flammable gases through the ducts. Moreover, the flammable gases have a large density and will gather at the bottom inside the explosion-proof hut main body 1, and the ducts cannot discharge the flammable gases well.

[0052] Therefore, turn on the second servo motor 56 and the two fans 52 to work simultaneously. The second servo motor 56 drives the rotating plate 55 to swing back and forth between the two mounting plates 51 around the hinge shaft. The rotating plate 55 drives the C-shaped plate 58 to swing. The C-shaped plate 58 drives the gear 54 and the connecting shaft 57 to swing. While swinging, the gear 54 rotates on the surface of the arc-shaped rack 53. The connecting shaft 57 drives the C-shaped plate 58 to swing horizontally on the rotating plate 55. Thus, the fan 52 swings horizontally while swinging longitudinally, effectively expanding the blowing range of the fan 52, so that the air flow inside the explosion-proof cabin main body 1 can be stirred and convected, effectively diluting the flammable gas inside the explosion-proof cabin main body 1, avoiding the deflagration situation caused by the accumulation of flammable gas in one place to a certain concentration. At the same time, when the fan 52 blows the gas to flow, it can accelerate the gas flow around the equipment inside the explosion-proof cabin main body 1 and dissipate heat from the equipment, avoiding the fire situation caused by overheating of the equipment.

[0053] As Figure 8 and Fig. 9 shown, the sealing assembly 59 includes a ventilation pipe 591 fixed to one side of the explosion-proof cabin main body 1. A fixing ring 592 is fixedly connected to the inner surface of the ventilation pipe 591. Two connecting rods 593 are slidably connected inside the fixing ring 592. One side of the two connecting rods 593 is fixedly connected with an annular magnet 595. A sealing block 594 is fixedly connected inside the annular magnet 595.

[0054] The sealing block 594 is frustum-shaped. The inner side surface of the fixing ring 592 fits with the outer surface of the sealing block 594. The material of the fixing ring 592 is metallic iron.

[0055] When an explosion actually occurs inside the explosion-proof cabin main body 1, it is necessary to seal the ventilation pipe 591 to prevent harmful substances generated by combustion from being discharged through the ventilation pipe 591. Therefore, when an explosion occurs inside the explosion-proof cabin main body 1, the strong air flow inside the explosion-proof cabin main body 1 will push the sealing block 594 to move, pushing the sealing block 594 to approach the fixing ring 592. When the sealing block 594 and the annular magnet 595 approach the fixing ring 592, the annular magnet 595 adsorbs with the fixing ring 592 to fix the sealing block 594 and fix the sealing block 594 inside the fixing ring 592, thereby sealing the inside of the explosion-proof cabin main body 1. At the same time, the sealing block 594 can be manually pulled by the connecting rod 593 to move into the fixing ring 592 for sealing.

[0056] Instructions for use: First, when a fire occurs inside the explosion-proof cabin main body 1, the thin rope 410 will be melted first, allowing the two box doors 46 to unfold, and the dry powder inside the first dry powder storage box 43 will be poured out to extinguish the equipment. The auxiliary fire extinguishing component 44 can be used to extinguish the equipment on the side wall of the explosion-proof cabin main body 1. The rectangular air distribution duct 454 can form an air curtain wall inside the explosion-proof cabin main body 1 to isolate the equipment on the side wall of the explosion-proof cabin main body 1 from the external oxygen, cut off the oxygen supply, and effectively extinguish the flames on the equipment.

[0057] Then, the convection component 5 can stir the airflow inside the explosion-proof cabin main body 1, so that the combustible gas inside the explosion-proof cabin main body 1 is continuously diluted to reduce the possibility of gas combustion. At the same time, the sealing component 59 can discharge the gas inside the explosion-proof cabin main body 1. At the same time, when an explosion occurs inside the explosion-proof cabin main body 1, the ventilation pipe 591 can be sealed by the sealing block 594.

[0058] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
