[0024] By setting the fifth heat-expandable sealing strip 401, the sealing between the fire door 102 and the first side frame 200 and the first L-shaped connecting strip 206 is improved, and by setting the third heat-expandable sealing strip 208, the sealing between the fire door 102 and the ground is improved.

[0025] As a further solution of the present invention, a fixing frame 204 is fixed to one side of the fire door 102, a first filling plate 205 is fixed to one side of the inner wall of the fixing frame 204, a first L-shaped connecting strip 206 is fixed to one side of the first filling plate 205, the first L-shaped connecting strip 206 is laterally located in the third side frame 203, and a second heat-expandable sealing strip 207 is fixed to one side of the fixing frame 204 and the first L-shaped connecting strip 206.

[0026] By providing the second heat-expandable sealing strip 207 , the sealing performance between the fire door 102 and the second side frame 202 and the third side frame 203 is improved.

[0027] As a further solution of the present invention, a guide rail 101 is fixed to the top of one side of the first wall 100, pulleys 103 are respectively fixed on both sides of the top surface of the third connecting frame 302, the pulleys 103 are movably connected to the guide rail 101, and a limiting slider 104 is fixed to the middle of the top surface of the third connecting frame 302, and the limiting slider 104 is movably engaged with the guide rail 101.

[0028] By providing the guide rail 101 , the pulley 103 and the limiting slider 104 , the position of the fire door 102 can be movably limited.

[0029] As a further solution of the present invention, a second wall 500 is arranged at a relative position of the first wall 100, a side opening 501 is opened on one side of the second wall 500, an installation frame 502 is fixed to the inner wall of the side opening 501, two doors and windows 503 are movably connected in the installation frame 502, a contact block 504 is fixed to one side of the door and window 503, a cylinder 505 is fixed to one side of the second wall 500, the output end of the cylinder 505 corresponds to the contact block 504, a temperature sensor 506 and a PLC controller 507 are fixed to one side of the second wall 500, and the temperature sensor 506 and the cylinder 505 are electrically connected to the PLC controller 507 respectively.

[0030] The temperature in the ward can be detected by the temperature sensor 506, and the door and window 503 on one side can be pushed by the cylinder 505, so that the ward is in a sealed state.

[0031] The first wall 100 and the second wall 500 are two walls in the ward, and a motor and a fire door 102 control component are arranged in the guide rail 101 to drive the fire door 102 to move.

[0032] This solution has the following working process: when a fire occurs in the ward, the temperature sensor 506 senses that the temperature in the ward has risen sharply. After the people in the ward escape from the ward, the fire door 102 is reset, so that the door is closed. Then the temperature sensor 506 transmits a signal to the PLC controller 507. The PLC controller 507 controls the cylinder 505 to start. The cylinder 505 starts and its output end pushes the contact block 504, so that the door and window 503 on one side are pushed closed. When the first heat-expandable sealing strip 201 expands due to heat, the fire door 102 and the first side frame 200 are sealed. When the second heat-expandable sealing strip 207 expands, the fire door 102 and the third side frame 203 are sealed. When the third heat-expandable sealing strip 208 expands, the bottom surface of the fire door 102 and the ground are sealed. When the fourth heat-expandable sealing strip 400 expands, the fire door 102 and the first connecting frame 300 are sealed. When the fifth heat-expandable sealing strip 401 expands, the fire door 102 and the side of the first side frame 200 and the side of the first L-shaped connecting strip 206 are sealed. Finally, all gaps are filled, so that the poisonous gas and fire in the ward will not enter the gap between the third connecting frame 302 and the first connecting frame 300 from the top position, and will not be discharged into the external environment through the gap between the second L-shaped connecting strip 304 and the first connecting frame 300, thereby effectively isolating the fire source.

[0033] When a fire occurs in the ward, the gas generated by the burning of the combustibles and the high temperature increase the activity of the gas molecules, causing the pressure in the ward to increase sharply. At this time, the gas pressure pushes the sealing plate 604, and the movement of the sealing plate 604 drives the first rack 605 to move. The movement of the first rack 605 drives the first gear 606 to rotate. The rotation of the first gear 606 drives the first rotating rod 608 to rotate, and then drives the cam 609 to rotate. The rotation of the cam 609 causes the sleeve frame 700 to be unrestricted. At this time, the second spring 704 pulls the sleeve frame 700 to move. , the first magnet 701 and the second magnet 707 do not correspond, and the second magnet 707 is unrestricted at this time, and the impact block 709 moves downward. The kinetic energy of the impact block 709 increases and hits the second mounting rod 902, thereby causing the second racks 900 on both sides to move downward. The downward movement of the second rack 900 drives the second gear 809 and the third gear 813 to rotate, thereby causing the first valve 807 and the second valve 811 to open, and ultimately causing the substances in the first fire extinguisher 806 and the second fire extinguisher 810 to be sprayed out to put out the fire in the ward.

[0034] According to the above working process, it can be known that: the fire door 102 and the first side frame 200 are sealed by the first heat-expandable sealing strip 201, the fire door 102 and the third side frame 203 are sealed by the second heat-expandable sealing strip 207, the bottom surface of the fire door 102 and the ground are sealed by the third heat-expandable sealing strip 208, the fire door 102 and the first connecting frame 300 are sealed by the fourth heat-expandable sealing strip 400, and the fire door 102 and the side of the first side frame 200 and the side of the first L-shaped connecting strip 206 are sealed by the fifth heat-expandable sealing strip 401, so that the poisonous gas and fire in the ward will not enter the gap between the third connecting frame 302 and the first connecting frame 300 from the top position, and will not spread to the external environment through the gap between the second L-shaped connecting strip 304 and the first connecting frame 300, thereby avoiding life-threatening situations.

[0035] By means of the temperature sensor 506, the cylinder 505 and the PLC controller 507, the door and window 503 on one side can be closed, so that the ward can be in a sealed state; by means of the sealing plate 604, the gas in the ward can push the sealing plate 604 to move; by means of the first gear 606 and the first rack 605, the cam 609 can rotate; by means of the sleeve 700 and the second spring 704, the first magnet 701 and the second magnet 707 can be separated; by means of the first magnet 701 and the second magnet 707, the position of the impact block 709 can be positioned by the positioning column 903; by means of the second rack 900, the second gear 809 and the third gear 813, the first valve 807 and the second valve 811 can be opened, so that the substances in the first fire extinguisher 806 and the second fire extinguisher 810 can be released to extinguish the fire in the ward, thereby timely and effectively controlling the fire.

A second mounting rod 902 is fixed to the top of a side surface where the two second racks 900 are close to each other, and a first mounting rod 901 is fixed to a position near the bottom of a side surface where the two second racks 900 are close to each other. Four positioning blocks 904 are fixed to the bottom of a side surface of the first wall 100, and a positioning column 903 is fixed between two positioning blocks 904 close to each other on a side surface. The first mounting rod 901 and the second mounting rod 902 are movably connected to the positioning column 903, and a second protective shell 803 is fixed to a side surface of the first wall 100, and the output ends of the first fire extinguisher 806 and the second fire extinguisher 810 pass through the second protective shell 803.

[0045] By setting the second rack 900, the second gear 809 and the third gear 813 on both sides can rotate simultaneously, so that the first valve 807 and the second valve 811 are opened, so that the substances in the first fire extinguisher 806 and the second fire extinguisher 810 can be sprayed out.

[0046] In summary: when a fire occurs in the ward, the temperature sensor 506 senses that the temperature in the ward has risen sharply. After the people in the ward escape from the ward, the fire door 102 is reset, so that the door is closed. Then the temperature sensor 506 transmits a signal to the PLC controller 507. The PLC controller 507 controls the cylinder 505 to start. The cylinder 505 starts and its output end pushes the contact block 504, so that the door and window 503 on one side are pushed closed. When the first heat-expandable sealing strip 201 expands due to heat, the fire door 102 is sealed with the first side frame 200. When the second heat-expandable sealing strip 207 expands, the fire door 102 is sealed with the third side frame 203. When the third heat-expandable sealing strip 207 expands, the fire door 102 is sealed with the third side frame 203. When the expansion sealing strip 208 expands, the bottom surface of the fire door 102 and the ground are sealed. When the fourth heat-expandable sealing strip 400 expands, the fire door 102 and the first connecting frame 300 are sealed. When the fifth heat-expandable sealing strip 401 expands, the fire door 102 and the side of the first side frame 200 and the side of the first L-shaped connecting strip 206 are sealed. Finally, all gaps are filled, so that the poisonous gas and fire in the ward will not enter the gap between the third connecting frame 302 and the first connecting frame 300 from the top position, and will not be discharged into the external environment through the gap between the second L-shaped connecting strip 304 and the first connecting frame 300, thereby effectively isolating the fire source.

[0047] When a fire occurs in the ward, the gas generated by the burning of the combustibles and the high temperature increase the activity of the gas molecules, causing the pressure in the ward to increase sharply. At this time, the gas pressure pushes the sealing plate 604, and the movement of the sealing plate 604 drives the first rack 605 to move. The movement of the first rack 605 drives the first gear 606 to rotate. The rotation of the first gear 606 drives the first rotating rod 608 to rotate, and then drives the cam 609 to rotate. The rotation of the cam 609 causes the sleeve frame 700 to be unrestricted. At this time, the second spring 704 pulls the sleeve frame 700 to move. , the first magnet 701 and the second magnet 707 do not correspond, and the second magnet 707 is unrestricted at this time, and the impact block 709 moves downward. The kinetic energy of the impact block 709 increases and hits the second mounting rod 902, thereby causing the second racks 900 on both sides to move downward. The downward movement of the second rack 900 drives the second gear 809 and the third gear 813 to rotate, thereby causing the first valve 807 and the second valve 811 to open, and ultimately causing the substances in the first fire extinguisher 806 and the second fire extinguisher 810 to be sprayed out to put out the fire in the ward.

[0048] The temperature sensor 506, the cylinder 505 and the PLC controller 507 can be purchased on the market, and are mature technologies in this field and have been fully disclosed, so they are not repeated in the specification.
