[0028] In this embodiment: the door body anti-stuck mechanism 2 includes a door frame 201 arranged on the inner side of the door frame base 1, a door body rotation support assembly is arranged on the inner side of the door frame 201, a fire door body 204 is arranged on the outer surface of the door body rotation support assembly, an explosion-proof perspective window 205 is arranged at the middle end of the fire door body 204, an anti-stuck assembly 208 is arranged at one end of the door body rotation support assembly, and an alarm light 207 is arranged at the front side of the fire door body 204. The anti-stuck assembly 208 includes a rotating gear 2081 arranged at one end of the door body rotation support assembly, a rack 2082 is meshed and arranged on one side of the rotating gear 2081, an electric hydraulic cylinder 2083 is arranged at one end of the rack 2082, and a cylinder 2084 is arranged on one side of the electric hydraulic cylinder 2083. The door body rotation support assembly includes a door body rotation shaft support platform 202 arranged on the inner side of the door frame 201, and a door body rotation shaft 203 is vertically arranged on one side of the door body rotation shaft support platform 202. A handle 206 is provided at the front end of the fire door body 204. The explosion-proof perspective window 205 is used to observe the smoke and fire situation on one side of the fire door body 204. The anti-stuck component 208 is used to drive the fire door body 204 to rotate mechanically. A guide groove is provided below the rack 2082, and its width is greater than the width of the rack 2082 to achieve longitudinal pushing. The alarm light 207 is used to alarm when smoke is detected. A moving platform is provided on one side of the electric hydraulic cylinder 2083.

[0029] In this embodiment: the mobile fireproof component 3 includes a smoke sensor 301 arranged on one side above the door body anti-stuck mechanism 2, a door opener 302 is arranged on one side of the smoke sensor 301, a fixed fireproof board 303 is arranged on one side of the door opener 302, and a mobile lifting fireproof board assembly is arranged below the fixed fireproof board 303. The mobile lifting fireproof board assembly includes a fireproof board bearing box 304 arranged below the fixed fireproof board 303, a lifting hydraulic cylinder 305 is arranged inside the fireproof board bearing box 304, and a telescopic mobile fireproof board 306 is arranged at the power telescopic end of the lifting hydraulic cylinder 305. A mounting rod is arranged on one side of the fixed fireproof board 303. The door opener 302 is used to assist in opening the fireproof door body 204, the fixed fireproof board 303 is used to provide fire protection for the smoke sensor 301 and the door opener 302, and the mobile lifting fireproof board assembly is used to provide smoke and fire protection for the fireproof door body 204.

[0030] Working principle: When in use, first, the door frame base 1 is fixedly installed on one side of the inner passage of the fire passage, and is installed together with the fire door body 204 on the opposite side of the door body rotating shaft support 202 through the door body rotating shaft 203. When a fire occurs, the smoke sensor 301 detects smoke and fire, and an alarm is sounded through the alarm light 207, and observation is carried out through the explosion-proof perspective window 205. When the fire is too large, the lifting hydraulic cylinder 305 inside the fireproof board carrying box 304 is started, driving the retractable movable fireproof board 306 to rise, and combined with the fixed fireproof board 303 for fire prevention. When the fire door body 204 needs to be opened, the electric hydraulic cylinder 2083 can be started, and then the rack 2082 is moved, which drives the rotating gear 2081 to rotate, and transmits the rotating force to the door body rotating shaft 203 by meshing. At this time, the door body rotating shaft 203 will rotate and rotate the fire door body 204 fixedly connected to its circumferential surface. At this time, the fire door body 204 will open. Through such a design, the fire door body 204 does not need to be opened manually, thereby improving the convenience of use. Moreover, since it is automatically opened, the probability of the fire door body 204 getting stuck can also be reduced, thereby improving the stability of the use of the device. When the rack 2082 and the rotating gear 2081 fail to operate, the cylinder 2084 can be started to drive the electric hydraulic cylinder 2083 and the rack 2082 to be pushed longitudinally to the side of the door frame base 1, so that the rack 2082 and the rotating gear 2081 are disengaged, and the fire door body 204 can be manually opened by the handle 206. Since a guide groove is provided under the rack 2082, and its width is greater than the width of the rack 2082, longitudinal pushing can be achieved without derailment.

[0031] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
