A fire door with automatic fire extinguishing function and its use method

Abstract

The present invention discloses a fire door with an automatic fire extinguishing function and a method for using the same. The door door comprises a door panel, and an extinguishing assembly is mounted on the front of the door panel. The extinguishing assembly is used to extinguish a fire that spreads to the bottom of the fire door. The present invention utilizes the door panel to install a fire. When a fire spreads to the bottom of the door panel, the flames, through high temperature, melt two side rubber sheets and a bottom rubber sheet in the extinguishing assembly, causing the side rubber sheets to no longer seal the side openings, and the bottom rubber sheet to no longer seal the bottom opening. This allows sand and soil inside the storage shell to flow out through the two side openings and the bottom opening, allowing the sand and soil to extinguish and block nearby flames, thereby preventing subsequent sand and soil from spreading to the bottom of the door panel. This allows the fire door to have an automatic fire extinguishing function.

[0019] Preferably, the method of using the fire door is as follows:

[0020] S1. First, after the staff installs the storage shell on the front of the door panel, they prepare two side rubber sheets and a bottom rubber sheet of appropriate sizes, and open small holes at appropriate positions of the two side rubber sheets and the bottom rubber sheet respectively. The staff inserts the two side rubber sheets into the inner sides of the two side frames through the side openings, so that the small holes of the side rubber sheets can correspond to the screw hole positions of the side frames. The staff inserts the bottom rubber sheet into the inner side of the bottom frame through the bottom opening, so that the small holes of the bottom rubber sheet can correspond to the screw hole positions of the bottom frame. The staff screws the four first bolts into the inner sides of the side frames in sequence, so that the first bolts move under the support of the thread of the side frame, so that the first bolts can move into the inner sides of the small holes of the side rubber sheets, so that the four first bolts can fix the side rubber sheets under the support of the side frames, thereby making the side rubber sheets To close the side opening, the staff screws the two second bolts into the inner side of the bottom frame in sequence, so that the second bolts move upward under the support of the threads of the bottom frame, so that the second bolts can move into the inner side of the small hole of the bottom rubber sheet, so that the two second bolts can fix the bottom rubber sheet under the support of the bottom frame, so that the bottom rubber sheet can close the bottom opening, and then the staff fills the inner side of the storage shell with sand, and the staff twists the shell cover, so that the shell cover rotates under the action of external force, so that the shell cover moves upward under the support of the threads of the shell inlet, so that the staff can open the shell cover, so that the staff can pour sand into the inner side of the storage shell through the shell inlet. When the storage shell is full of sand, the staff tightens the shell cover to the outer side of the shell inlet, so that the shell cover closes the shell inlet;

[0021] S2. When a fire occurs, the temperature of the surrounding air rises due to the fire, so that the temperature detector in the smart module can detect that the temperature of the surrounding air has exceeded the set temperature value, so that the temperature detector feeds back a signal to the alarm in the smart module, so that the alarm sounds an alarm and feeds back the information to the signal device in the smart module, so that the signal device transmits the information to the smart lock, so that the smart lock opens;

[0022] S3. When the fire subsequently spreads to the bottom of the door panel, the flames melt the two side rubber sheets and the bottom rubber sheet in the extinguishing assembly through the high temperature, so that the side rubber sheets no longer seal the side openings, and the bottom rubber sheet no longer seals the bottom opening. This allows the sand inside the storage shell to flow out through the two side openings and the bottom opening, allowing the sand to extinguish and block the nearby flames, thereby preventing the sand from continuing to spread to the bottom of the door panel.

[0023] S4. When the escapee reaches the front of the door panel, he turns the knob in the storage assembly, causing the knob to move downward under the threaded support of the fixed platform and the threaded piece, so that the knob can move away from the inner side of the threaded piece, so that the knob no longer cooperates with the threaded piece to seal the bottom opening of the water tank, so that the water inside the water tank can flow downward through the bottom opening of the water tank and the threaded piece, so that the water can flow to the inner side of the top box through the inclination of the inclined shell, so that the cotton cloth stored inside the top box absorbs the water. The escapee moves the top cover upward to move the blocking block out of the inner side of the top box, and moves the handle upward. Under the action of external force, the handle drives the bottom plate to move upward along the inner side of the top box through the long rod and the side block, so that the bottom plate can drive the cotton cloth upward under the action of external force, so that the escapee can take the cotton cloth at the top of the top box, and the escapee takes protective measures by covering his mouth and nose with the wet cotton cloth;

[0024] The escaping person moves and rotates the housing so that the housing can be driven by the inner rod, the housing, the rotating block and the fastening bolt to move along the inner side of the guide housing under the action of the external force, so that the housing can move to the outside of the handle. The escaping person pulls the handle through the housing so that the handle drives the door panel to move under the action of the external force.

[0025] S6. Then, under the action of external force, the door panel can rotate around the hinge, so that the door panel and the door frame are perpendicular to each other, allowing the escaping person to open the door panel;

[0026] S7. The escapee then vertically rotates the pull rod in the fixing assembly, causing the pull rod to rotate around the short bolt under the action of external force. When the pull rod rotates to separate from the short plate, the short plate no longer fixes and supports the pull rod, allowing the second spring to use its own elastic force to drive the pressure plate to move. Under the action of external force, the pressure plate can drive the round block to move into the inner side of the socket, thereby fixing the opened door panel, thereby facilitating the escape of subsequent escapees.

[0027] Preferably, in step S4, the following steps are also included:

[0028] S41. The staff turns the knob in the storage assembly, screws the knob into the inner side of the threaded piece, and turns the box cover to rotate under the action of external force, so that the box cover moves upward under the support of the thread of the box inlet, so that the staff can open the box cover. The staff uses tools to pour water into the inner side of the water tank through the box inlet. When the water tank is full of water, the staff tightens the box cover to the outside of the box inlet to close the box inlet.

[0029] Compared with the prior art, the present invention has the following beneficial effects:

[0030] 1. The present invention is equipped with a door panel. When the fire spreads to the bottom of the door panel, the flames melt the two side rubber sheets and the bottom rubber sheet in the extinguishing assembly through high temperature, so that the side rubber sheets no longer seal the side openings, and the bottom rubber sheet no longer seals the bottom opening. Sand and soil inside the storage shell can flow out through the two side openings and the bottom opening, so that the sand and soil can extinguish and block nearby flames, thereby preventing subsequent sand and soil from continuing to spread to the bottom of the door panel. As a result, the fire door has an automatic fire extinguishing function, which increases its practicality.

[0031] The escaping person can remove the blocking block out of the inner side of the top box by moving the top cover upwards, and can also remove the blocking block out of the inner side of the top box by moving the handle upwards. The escaping person can remove the blocking block out of the inner side of the top box by moving the top cover upwards, and can also remove the blocking block out of the inner side of the top box by moving the handle upwards. The escaping person can remove the blocking block out of the inner side of the top box by moving the top cover upwards, and can also remove the blocking block out of the inner side of the top box by moving the handle upwards.

[0032] 3. The present invention is equipped with an anti-scalding component. When the escapee pulls the movable plate in the anti-scalding component, the movable plate can drive the insertion rod to move under the action of external force, so that the insertion rod can move out of the inner side of the through hole and no longer fix the housing. The escapee twists the fastening bolt, so that the fastening bolt moves under the thread support of the support block, so that the fastening bolt no longer cooperates with the support block to squeeze the rotating block to fix the rotating block. The escapee moves and rotates the housing, so that the housing can drive the rotating block to rotate around the fastening bolt as the center through the inner rod and the cylinder shell under the action of external force. At the same time, the housing The shell can drive the inner rod to move along the inner side of the cylinder shell under the action of external force, so that the shell can be moved to the side of the handle. The staff moves the shell horizontally, so that the shell drives the slider to move through the inner rod, cylinder shell, rotating block, fastening bolt and supporting block under the action of external force, so that the slider can move along the inner side of the guide shell, so that the shell can be moved to the outside of the handle. The escapee pulls the handle through the shell, so that the handle drives the door panel to move under the action of external force, so that the anti-scalding component can facilitate the escapee to open the door panel by pulling the handle.

[0033] 4. The present invention is equipped with a fixing assembly. The escapee rotates the pull rod in the fixing assembly vertically, so that the pull rod rotates around the short bolt under the action of external force. When the pull rod is rotated to separate from the short plate, the short plate no longer provides fixed support for the pull rod, so that the second spring can use its own elastic force to drive the pressure plate to move, so that the pressure plate can drive the round block to move into the inner side of the socket under the action of external force, so that the fixing assembly can easily fix the opened door panel, thereby facilitating the escape of subsequent escapees.

The three round blocks 56 and the square block 61 cooperate with each other to fix the opened door panel 1, thereby facilitating the escape of subsequent escape personnel.

[0055] Further, the use of fire doors is as follows:

[0056] S1. First, after the staff installs the storage shell 6 on the front of the door panel, they prepare two side rubber sheets 13 and a bottom rubber sheet 17 of appropriate sizes, and open small holes at appropriate positions of the two side rubber sheets 13 and the bottom rubber sheet 17 respectively. The staff inserts the two side rubber sheets 13 into the inner sides of the two side frames 11 through the side openings 12, so that the small holes of the side rubber sheets 13 can correspond to the screw hole positions of the side frames 11. The staff inserts the bottom rubber sheet 17 into the inner side of the bottom frame 15 through the bottom opening 16, so that the small holes of the bottom rubber sheet 17 can correspond to the screw hole positions of the bottom frame 15. The staff screws the four first bolts 14 into the inner sides of the side frames 11 in sequence, so that the first bolts 14 move under the support of the threads of the side frames 11, so that the first bolts 14 can move into the inner sides of the small holes of the side rubber sheets 13, so that the four first bolts 14 can fix the side rubber sheets 13 under the support of the side frames 11, thereby making the side rubber The film 13 can close the side opening 7. The staff screws the two second bolts 18 into the inner side of the bottom frame 15 in turn, so that the second bolts 18 move upward under the threaded support of the bottom frame 15, so that the second bolts 18 can move into the inner side of the small hole of the bottom rubber sheet 17, so that the two second bolts 18 can fix the bottom rubber sheet 17 under the support of the bottom frame 15, so that the bottom rubber sheet 17 can close the bottom opening 8. Then the staff fills the inner side of the storage shell 6 with sand, and the staff twists the shell cover 10 so that the shell cover 10 rotates under the action of external force, so that the shell cover 10 moves upward under the threaded support of the shell inlet 9, so that the staff can open the shell cover 10, so that the staff can pour sand into the inner side of the storage shell 6 through the shell inlet 9. When the storage shell 6 is full of sand, the staff tightens the shell cover 10 to the outside of the shell inlet 9, so that the shell cover 10 closes the shell inlet 9.

[0057] S2. When a fire occurs, the temperature of the surrounding air rises due to the fire, so that the temperature detector in the smart module can detect that the temperature of the surrounding air has exceeded the set temperature value, so that the temperature detector feeds back a signal to the alarm in the smart module, so that the alarm sounds an alarm and feeds back the information to the signal device in the smart module, so that the signal device transmits the information to the smart lock 3, so that the smart lock 3 is unlocked;

[0058] S3. When the fire spreads to the bottom of the door panel 1, the flames melt the two side rubber sheets 13 and the bottom rubber sheet 17 in the extinguishing assembly due to the high temperature. The side rubber sheets 13 no longer seal the side openings 12, and the bottom rubber sheet 17 no longer seals the bottom opening 16. The sand inside the storage shell 6 can flow out through the two side openings 7 and the bottom opening 8, so that the sand can extinguish and block the nearby flames, thereby preventing the sand from continuing to spread to the bottom of the door panel 1.

[0059] S4. When the escapee reaches the front of the door panel 1, the knob 35 in the storage assembly is turned, so that the knob 35 moves downward under the threaded support of the fixing platform 29 and the threaded piece 33, so that the knob 35 can move away from the inner side of the threaded piece 33, so that the knob 35 no longer cooperates with the threaded piece 33 to close the bottom opening of the water tank 30, so that the water inside the water tank 30 can flow downward through the bottom opening of the water tank 30 and the threaded piece 33, so that the water can flow to the inner side of the top box 19 through the inclination of the inclined shell 34, so that the top box 19 The cotton cloth 21 stored inside absorbs the water. The escapee moves the top cover 23 upward to remove the blocking block 22 from the inside of the top box 19, and moves the handle 28 upward. Under the action of external force, the handle 28 drives the bottom plate 25 to move upward along the inside of the top box 19 through the long rod 27 and the side block 26. Under the action of external force, the bottom plate 25 can drive the cotton cloth 21 upward, so that the escapee can take the cotton cloth 21 at the top of the top box 19. The escapee takes protective measures by covering his mouth and nose with the wet cotton cloth 21.

[0060] S5. Then the escapee pulls the movable plate 49 in the anti-scalding assembly, so that the movable plate 49 can drive the insertion rod 50 to move under the action of external force, so that the insertion rod 50 can move out of the inner side of the through hole 45 and no longer fix the housing 44. The escapee twists the fastening bolt 39, so that the fastening bolt 39 moves under the threaded support of the support block 38, so that the fastening bolt 39 no longer cooperates with the support block 38 to squeeze the rotating block 40 to fix the rotating block 40. The escapee moves and rotates the housing 44, so that the housing 44 can drive the rotating block 40 with the fastening bolt 39 as the center through the inner rod 42 and the cylinder shell 41 under the action of external force. The sleeve 44 rotates, and at the same time, the sleeve 44 can drive the inner rod 42 to move along the inner side of the cylinder shell 41 under the action of external force, so that the sleeve 44 can move to the side of the handle 2. The staff moves the sleeve 44 horizontally, so that the sleeve 44 drives the slider 37 to move through the inner rod 42, the cylinder shell 41, the rotating block 40, the fastening bolt 39 and the supporting block 38 under the action of external force, so that the slider 37 can move along the inner side of the guide shell 36, so that the sleeve 44 can move to the outside of the handle 2. The escapee pulls the handle 2 through the sleeve 44, so that the handle 2 drives the door panel 1 to move under the action of external force;

[0061] S6. Then, under the action of external force, the door panel 1 can rotate around the hinge 5, so that the door panel 1 and the door frame 4 are at a vertical angle, allowing the escaping person to open the door panel 1;

[0062] S7. The escapee then vertically rotates the pull rod 59 in the fixing assembly, causing the pull rod 59 to rotate around the short bolt 58 under the action of an external force. When the pull rod 59 rotates to separate from the short plate 60, the short plate 60 no longer fixes and supports the pull rod 59, allowing the second spring 54 to use its own elastic force to drive the pressure plate 55 to move. Under the action of an external force, the pressure plate 55 can drive the round block 56 to move into the inner side of the insertion hole 62, thereby fixing the opened door panel 1, thereby facilitating the escape of subsequent escapees.

[0063] Furthermore, in step S1, the following steps are also included:

[0064] S41. The staff turns the knob 35 in the storage assembly, screws the knob 35 into the inner side of the threaded piece 33, and turns the box cover 32 to rotate under the action of external force, so that the box cover 32 moves upward under the support of the thread of the box inlet 31, so that the staff can open the box cover 32. The staff uses a tool to pour water into the inner side of the water tank 30 through the box inlet 31. When the water tank 30 is filled with water, the staff tightens the box cover 32 to the outside of the box inlet 31 to close the box inlet 31.

[0065] Working principle: Before using the device, it is necessary to check whether there are any problems that affect its use. When the fire spreads to the bottom of the door panel 1, the flame will extinguish the side rubber sheet 13 and the bottom rubber sheet 17 in the extinguishing assembly, causing sand to flow out through the side opening 7 and the bottom opening 8, so that the sand will extinguish the flame at the bottom of the door panel 1. When the escapee escapes to the front of the door panel 1, he turns the knob 35 in the storage assembly downward and unscrews the knob 35 from the inner side of the threaded sheet 33, so that water flows into the inner side of the top box 19 through the inclined shell 34, so that the water is absorbed by the cotton cloth 21, and the escapee opens the top box. Cover 23, by moving the handle 28 upward, take out the cotton cloth 21 at the top of the top box 19, cover the mouth and nose with the cotton cloth 21 for protection, move the movable plate 49 to move the insertion rod 50 out of the inner side of the through hole 45, the escapee moves and rotates the sleeve 44, puts the sleeve 44 on the outside of the handle 2, pulls the handle 2 through the sleeve 44 to open the door panel 1, rotates the pull rod 59, and when the pull rod 59 is moved away from the short plate 60, the round block 56 is moved into the inner side of the insertion hole 62 by the elastic force of the second spring 54, fixes the opened door panel 1, and the escapee can escape.
