[0024] 4: This fire-proof structure based on the building curtain wall has the advantage of absorbing smoke when protecting the building. Through the setting of fan 1, the indoor smoke can be transferred to the outside. When the indoor fire-proof structure forms a water curtain, the fan 1 can be reversed to suck the outdoor air into the room. By using the air flow vortex, a small amount of smoke can be guided to the water curtain under the flow of air flow for smoke absorption.

[0025] In summary, the present invention realizes the conversion of indoor and outdoor air by utilizing the centrifugal force generated during rotation, transfers the indoor smoke to the outdoors, and realizes targeted fire extinguishing according to the concentration of smoke in the fire. When the fire is large, the whole room can be sprayed, and a graded fire extinguishing treatment can be carried out according to the size of the fire, which can protect the curtain wall and prevent the fire from spreading.

The installation box 2 is made of fire-proof material (such as steel material). A fire prevention device is installed between the installation box 2 and the two curtain walls 3 to prevent damage to the device in the installation box 2 when the fire is large. The fire prevention device includes an L-shaped plate fixedly installed between the floor 1 and the installation box 2. A mounting hole is formed between the floor 1, the keel 6, the installation box 2 and the L-shaped plate. A blocking plate 7 is installed in the mounting hole. The blocking plate 7 can increase the sealing of the installation box 2 to prevent smoke and dust from entering the gap between the floor 1, the keel 6, the installation box 2 and the L-shaped plate. Card plates 10 are fixedly installed on the upper and lower sides of the installation box 2. Curtain walls 3 and installation plates 4 are fixedly installed on the two card plates 10, and the two installation plates 4 are fixedly connected to the corresponding curtain walls 3. A galvanized steel plate 5 is fixedly installed between the installation plate 4, the card plate 10 and the installation box 2.

[0050] The contacting parts among the floor 1, the installation box 2, the curtain wall 3, the installation plate 4, the galvanized steel plate 5, the keel 6, the bracket 10 and the L-shaped plate are all connected by fire-resistant sealant to prevent damage to the above structures and cause the installation box 2 to fall when a fire occurs.

A gas dispersion device is installed on the plurality of circular tubes 8, and a chain 21 is installed on the plurality of gas dispersion devices. The gas dispersion device includes a plurality of sliding circular grooves opened on the outdoor side of the circular tube 8, and sliding rods 27 are slidably installed in the plurality of sliding circular grooves. A circular plate 9 is fixedly installed between the plurality of sliding rods 27. A limiting ring 23 is fixedly installed on the side of the circular plate 9 close to the installation box 2. The limiting ring 23 is provided with a plurality of grooves with end faces in the shape of a "convex" character, and connecting rods 28 are slidably installed in the plurality of convex character grooves, and one end of the connecting rod 28 located in the convex character groove is also provided with a convex character protrusion used in conjunction with it, so that the connecting rod 28 can slide in the corresponding convex character groove without detaching.

[0052] A motor 19 is fixedly installed in the installation box 2, and a driving shaft is fixedly installed on the driving end of the motor 19. A conical ring 24 is slidably installed on multiple connecting rods 28, and the diameter of the part of the conical ring 24 close to the circular plate 9 is larger. The conical ring 24 is provided with multiple square grooves at an inclined position, and multiple connecting rods 28 are "L"-shaped. The square groove has a certain depth, which can enable multiple connecting rods 28 to slide in the corresponding square grooves without falling off. Multiple mounting rods 29 are fixedly installed on the conical ring 24, and a rotating shaft 26 is fixedly installed on the multiple mounting rods 29. A support frame (not shown in the figure) is fixedly installed in the circular tube 8, and a bearing is fixedly installed on the support frame, and the rotating shaft 26 is rotatably sleeved in the bearing. A fan 20 is fixedly installed on the rotating shaft 26, and the fan 20 is driven by the rotation of the rotating shaft 26. 20. Multiple mounting rods 29, the conical ring 24 and the multiple connecting rods 28 rotate together. When the multiple connecting rods 28 rotate, the centrifugal force generated by the rotation can make the multiple connecting rods 28 slide in the corresponding square grooves (from the smaller diameter position on the conical ring 24 to the larger diameter position). At the same time, the multiple connecting rods 28 slide in the multiple convex grooves of the limiting ring 23 toward the edge of the limiting ring 23, which can separate the circular plate 9 from the circular tube 8 to achieve natural ventilation in the room, or use the conversion of internal and external airflows in the event of a fire to transfer indoor smoke to the outdoors. A gear 22 is fixedly installed at one end of the rotating shaft 26 away from the conical ring 24, and a gear three meshing with the chain 21 is fixedly installed at one end of the driving shaft, and the chain 21 is rotatably sleeved on the gear three and the multiple gears 22.

[0053] The motor 19 drives the driving shaft to rotate, and the chain 21 can be used to realize the simultaneous rotation of multiple fans 20.

[0054] Reference Figure 3 , Figure 12-13A mounting cylinder 33 is fixedly installed in the mounting box 2, and the driving shaft and the mounting cylinder 33 are connected by a bevel gear set 36. The bevel gear set 36 consists of a bevel gear 2 and a bevel gear 3. Bevel gear 2 and bevel gear 3 are fixedly installed on the driving shaft, and bevel gear 2 and bevel gear 3 have the same shape and size and are symmetrically arranged on the driving shaft. A smoking device is cooperatedly installed between the mounting cylinder 33 and the mounting box 2, and the smoking device includes two suction pipes 38 fixedly connected to the mounting cylinder 33. Two placement holes are opened on the mounting box 2, and the lower ends of the two suction pipes 38 pass through the corresponding placement holes and extend to the bottom of the mounting box 2.

[0055] A fixing frame is fixedly installed in the installation tube 33, and a rotating rod 37 is rotatably installed on the fixing frame. A circular hole is opened at the bottom of the installation tube 33, and the lower end of the rotating rod 37 passes through the circular hole and extends to the bottom of the installation tube 33. A second fan 39 is fixedly installed at one end of the rotating rod 37 located in the installation tube 33. The rotation of the second fan 39 can suck the indoor smoke into the installation tube 33 through two suction pipes 38, and the internal diameters of the two suction pipes 38 are set to be small to prevent the sucked smoke from flowing out again through the two suction pipes 38 when the second fan 39 is running.

[0056] A bevel gear 1 meshing with the bevel gear set 36 is fixedly installed at the lower end of the rotating rod 37. Bevel gear 1 meshes with bevel gear 2 and bevel gear 3. One-way bearings are fixedly installed on bevel gear 2 and bevel gear 3. The two one-way bearings are rotatably sleeved on the drive shaft, and the rotation directions of the two one-way bearings are opposite. When the drive shaft rotates forward and backward, the bevel gear 1 can always be driven to rotate, thereby realizing that the fan 2 39 always rotates, and the rotation direction is always the same.

[0057] An installation tube 13 is fixedly connected between the installation cylinder 33 and the installation box 2, and one end of the installation tube 13 extends to the outside of the installation box 2. One end of the installation tube 13 is arranged outdoors to prevent smoke inside the installation box 2 from entering through both ends of the installation tube 13, thereby preventing the internal structure of the installation tube 13 from being affected.

[0058] A pushing mechanism is installed between the mounting tube 13 and the connecting plate 30, and the pushing mechanism includes a through hole opened on the mounting tube 13, and the through hole is located outside the mounting box 2, and the through hole is horizontally opened on the mounting tube 13, and a straight rod 25 is slidably installed in the through hole, and a pushing rod 41 is fixedly installed on the straight rod 25, and a pushing plate 40 that is sealed and slidable in the mounting tube 13 is fixedly installed on the pushing rod 41, and a plurality of smoke holes are opened on the pushing rod 41, when the fan 2 39 sucks the smoke into the mounting tube 33 through the two suction pipes 38, when the particle concentration in the smoke is small, it will pass through the plurality of smoke holes, and the smoke will not push the pushing rod 41 to move, and when the particle concentration in the smoke is large, the plurality of smoke holes will be blocked, and the pushing rod 41 moves in the mounting tube 13 under the push of the smoke.

[0059] A plate is fixedly installed on the mounting tube 13, and a spring 35 is fixedly installed between the plate and the straight rod 25. When the push rod 41 moves under the action of smoke, the spring 35 is compressed. When there is no smoke in the mounting tube 33, the spring 35 drives the push rod 41 to return to the initial state again.

[0060] Both ends of the straight rod 25 are fixedly mounted with pull rods 34 . Two small holes are opened on the installation box 2 , and one end of the two pull rods 34 passes through the corresponding small holes and is fixedly mounted on the connecting plate 30 .

[0061] Reference Fig.11 , Figure 14-Figure 19 A connecting plate 30 is installed on the smoking device, and a plurality of water discharge devices are installed between the connecting plate 30 and the installation box 2. The water discharge device includes a moving rod 32 fixedly installed on the connecting plate 30. The shape of the moving rod 32 is L-shaped. A water tank 16 is fixedly installed in the installation box 2. A square hole is opened on the water tank 16, and the lower end of the moving rod 32 passes through the square hole and extends into the water tank 16. The moving rod 32 slides in the square hole. A folding plate can be set between the square hole and the moving rod 32. Under the action of the folding plate, the moving rod 32 can be realized. In order to move the water tank 16 and prevent the water in the water tank 16 from overflowing, a tooth plate 43 is fixedly installed at the lower end of the moving rod 32, and a long rod is rotatably installed in the water tank 16, on which a gear 2 44 is fixedly installed, and a tooth plate 43 is also meshedly installed below the gear 2 44, and the toothed parts on the two tooth plates 43 are arranged on two adjacent surfaces, so that the gear 2 44 can mesh with the two tooth plates 43, and a fixed rod 42 is fixedly installed on the lower tooth plate 43, and a baffle 1 is fixedly installed on the upper end of the fixed rod 42, and a baffle 2 is fixedly installed on the lower end of the fixed rod 42.

[0062] Baffle plate 1 is in contact with the side wall of water tank 16, baffle plate 2 is in contact with the bottom wall of water tank 16, and in a horizontal state, baffle plate 1 is located on the right side of baffle plate 2 (refer to Fig.15 ), rubber pads can be provided on the sides where the baffle plate 1 and the baffle plate 2 are in contact with the water tank 16 to ensure the sealing of the water tank 16.

[0063] A soot blowing mechanism used in conjunction with the round pipe 8 is installed on each of the multiple water tanks 16 . The soot blowing mechanism includes a dust removal pipe 18 fixedly connected to the water tank 16 .

[0064] When the smoke concentration in the installation tube 33 is small, the movement of the push rod 41 can drive the moving rod 32 to move through the two pull rods 34 and the connecting plate 30, but the moving distance is small at this time, so that the upper tooth plate 43 can drive the lower tooth plate 43 to move in the water tank 16 through the gear 2 44, thereby realizing the movement of the fixed rod 42, thereby driving the upper baffle 1 to separate from the inner wall of the water tank 16, so that the water inlet end of the dust removal pipe 18 is opened, and the water in the water tank 16 flows out through the dust removal pipe 18.

[0065] The dust removal pipe 18 is fixedly connected to the annular pipe 17, and multiple dust removal pipes 18 are also fixedly connected to the annular pipe 17. The multiple dust removal pipes 18 are evenly arranged on the annular pipe 17, and the water outlet ends of the multiple dust removal pipes 18 are all located in the circular pipe 8. Through the water outlet of the multiple dust removal pipes 18, the smoke and dust on the running fan 20 can be sprayed and cleaned to prevent the rotation efficiency of the fan 20 from being reduced.

[0066] A spray mechanism is installed on multiple water tanks 16, and the spray mechanism includes a connecting pipe 11 fixedly connected to the water tank 16 and the installation box 2, and the lower end of the connecting pipe 11 extends outside the installation box 2 for connecting to a fire water source. The water tank 16 and the installation box 2 are jointly fixedly connected with a fixed pipe 45 used in conjunction with the baffle 2, and the lower end of the fixed pipe 45 extends to the bottom of the installation box 2.

[0067] When the smoke concentration in the installation tube 33 is relatively high, the movement of the push rod 41 can cause the movement of the fixed rod 42 to drive the baffle plate 2 to separate from the bottom wall of the water tank 16, so that the water inlet end of the fixed pipe 45 is opened, and the water in the water tank 16 flows out through the fixed pipe 45.

[0068] The nozzle 31 is rotatably mounted on the lower end of the fixed tube 45, an arc-shaped convex ring is arranged around the outer side of the upper end of the nozzle 31, and an arc-shaped annular groove cooperating therewith is arranged in the fixed tube 45, a rubber ring is arranged in the arc-shaped annular groove, so that the nozzle 31 can be sealed and rotated in the fixed tube 45, and a gear ring 47 is fixedly mounted on the nozzle 31.

[0069] The installation box 2 is provided with a guide assembly for use with a plurality of gear rings 47. The guide assembly includes a strip hole provided on the lower surface of the installation box 2. The installation box 2 is fixedly provided with a guide plate 12 for use with the nozzle 31. The guide plate 12 is composed of four plates. Fig.19 As shown, it is composed of square plates and short plates and long plates on both sides. The short plates and long plates are fixed on both sides of the two square plates, and the holes formed between the square plates and the short plates and long plates are the same in shape and size as the strip holes on the installation box 2, and are connected to the strip holes.

[0070] The water outlet end of the nozzle 31 is initially located on one side of the long plate on the guide plate 12. When the nozzle 31 sprays water, the water forms a water curtain through the long plate, which blocks the fire source and achieves the effect of isolating oxygen. At the same time, water can be used to absorb smoke, reducing the probability of flames jumping out of the curtain wall, protecting the curtain wall, reducing the temperature on the curtain wall, and reducing the probability of the glass curtain wall bursting.

[0071] A sensor is fixedly installed at the connecting plate 30 in the installation box 2. When the pipe mouth of the fixed pipe 45 is opened, the movement distance of the connecting plate 30 causes the sensor to control the driving end of the motor 19 to rotate in the opposite direction, thereby driving the fan 20 to rotate in the opposite direction, sucking outdoor air into the installation box 2, and blowing out the air flow through the square hole. At this time, the fan 20 is blocked by the circular plate 9, and the air suction is blocked. The air suction flow cannot keep up with the rotation speed, and negative pressure is formed at the end of the fan blade to retain the gas, forming a vortex, and the air is discharged from the side, thereby sucking the indoor air into the water curtain to adsorb the smoke.

[0072] A square sliding hole is formed on the short plate of the guide plate 12 , in which a sliding plate 46 is slidably mounted, and a plurality of gear rods 48 meshing with corresponding gear rings 47 are fixedly mounted on the sliding plate 46 .

[0073] A plurality of temperature transfer barrels 14 are fixedly installed on the lower surface of the installation box 2. The plurality of temperature transfer barrels 14 are filled with liquid, such as promethazine. When the fire is large, the temperature transfer barrels 14 can use the sensed temperature to heat the internal liquid to make it boil. The plurality of temperature transfer barrels 14 are fixedly connected with a flow guide pipe 15, and the temperature transfer barrels 14 and the flow guide pipe 15 are made of metal material to prevent them from being damaged by the fire. The plurality of flow guide pipes 15 are sealed and slidably provided with pistons, and the plurality of pistons are fixedly provided with rod bodies, and the plurality of rod bodies are fixedly connected to the sliding plate 46.

[0074] As the liquid boils, the air pressure in the temperature transfer barrel 14 increases, driving the piston and the rod body to slide in the guide tube 15, thereby driving the sliding plate 46 to move toward the long plate, so that the strip hole is sealed, preventing smoke and fire from entering the installation box 2. When the strip hole is sealed, the fan 20 stops working and stops sucking gas.

[0075] At the same time, the movement of the sliding plate 46 drives the gear rod 48 to move, and drives the nozzle 31 to rotate 180 degrees through the gear ring 47. At this time, the upper end of the nozzle 31 is located on one side of the installation box 2, which can spray a large area indoors and extinguish the indoor fire source.

[0076] At the same time, a temperature alarm can be set at the temperature transfer barrel 14, which can send out an alarm based on the temperature to remind people of the occurrence of fire and assist people in escaping.

[0077] It is further explained that the above-mentioned fixed connection should be understood in a broad sense unless otherwise clearly specified and limited. For example, it can be welding, gluing, or one-piece molding, etc., which are conventional means well known to those skilled in the art.

[0078] The specific operation steps of the present invention are as follows:

[0079] When there is a small amount of smoke in the room: turn on the motor 19 to drive the gear three to rotate through the driving shaft, the gear three rotates through the chain 21 to drive multiple gears 1 22 to rotate, the multiple gears 1 22 rotate through the corresponding rotating shaft 26 to drive the fan 1 20 to rotate, and the rotating shaft 26 rotates while driving the conical ring 24 to rotate through multiple mounting rods 29. At this time, under the action of centrifugal force, the limit ring 23 and the circular plate 9 are driven by multiple connecting rods 28 to separate from the conical ring 24 while rotating, and the fan 1 20 extracts the smoke in the room through the strip holes on the mounting box 2, and discharges the smoke in the room through the gap between the conical ring 24 and the circular plate 9.

[0080] When the indoor smoke increases: the driving shaft rotates and the bevel gear 2 in the bevel gear set 36 drives the bevel gear 1 and the rotating rod 37 to rotate. The rotating rod 37 drives the fan 2 39 to rotate through the two suction pipes 38 to suck the indoor smoke into the installation tube 33. The large particle concentration in the smoke drives the push plate 40 and the push rod 41 to slide in the installation tube 13. The push rod 41 drives the straight rod 25 to slide and squeeze the spring 35. At the same time, the straight rod 25 slides through the two pull rods 34 to drive the connecting plate 30 to move. The movement of the fan 2 39 drives the multiple moving rods 32 to move to the right. The movement of the moving rod 32 drives the gear 2 44 to rotate clockwise. The gear 2 44 rotates clockwise to drive the toothed plate 43 to move to the left (refer to Fig.15 ), the tooth plate 43 moves to the left to drive the fixing rod 42 and the baffle plate 1 to separate from the corresponding dust removal pipe 18, so that the water in the water tank 16 passes through the annular pipe 17 and multiple dust removal pipes 18 to remove the soot adhered to the fan 20.

[0081] When the fire increases: the sliding distance of the push plate 40 in the installation pipe 13 increases, thereby driving the fixed rod 42 to move a longer distance, so that the fixed rod 42 moves to drive the baffle plate 2 to separate from the upper pipe opening of the fixed pipe 45, and the water in the water tank 16 is sprayed out through the fixed pipe 45 and the nozzle 31. The water sprayed from the nozzle 31 forms a water curtain under the obstruction of the guide plate 12 to block the fire;

[0082] At the same time, the driving end of the motor 19 is controlled to rotate in the opposite direction. At this time, the fan 20 rotates in the opposite direction, and the outdoor air is sucked into the installation box 2 through the gap between the circular plate 9 and the conical ring 24, and blown into the room through the strip holes. At this time, the suction space of the fan 20 is insufficient due to the obstruction of the circular plate 9, and the suction flow rate cannot keep up with the rotation speed. Negative pressure is formed at the end of the fan blade to retain the gas and form a vortex. At this time, the indoor wind will be drawn into the water curtain along with the vortex to absorb the smoke.

[0083] When the temperature of the fire causes the liquid in the temperature transfer barrel 14 to boil: at this time: multiple pistons are pushed, driving the rod body to push multiple sliding plates 46 to seal the guide plate 12 to prevent smoke from entering the installation box 2, and at the same time, the movement of the sliding plate 46 drives the gear rod 48 to move, and the movement of the gear rod 48 drives the nozzle 31 to rotate through the gear ring 47 to spray the indoor space and achieve the fire extinguishing effect.

[0084] The above description is only a preferred specific implementation manner of the present invention, but 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 scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
