Description

Technical Field

[0001] The utility model relates to the technical field of civil air defense equipment, in particular to a civil air defense door for emergency escape in case of fire. Background Art

[0002] In modern building design and urban safety planning, fire safety management is an important component that cannot be ignored. Especially in public places such as shopping malls and hospitals, where there are dense crowds of people, it is crucial to evacuate and block the spread of fire quickly and effectively once a fire occurs. In this context, as one of the important safety facilities in wartime, the design and function of civil air defense doors are directly related to the safe evacuation of personnel and the protection of life and property in case of fire. Therefore, continuous innovation and optimization of the technical requirements and functional implementation methods of civil air defense doors has become one of the important directions of current research on fire prevention and control technology.

[0003] Deficiencies of existing technology:

[0004] At present, the common civil air defense doors are mainly composed of one or two heavy-duty door bodies, which have certain fireproof and sealing properties. They are designed to block the spread of fire and smoke by closing the door body when a fire occurs. These doors are usually equipped with simple opening and closing mechanisms and rely on physical force to operate. However, in the face of emergency situations such as fires, the existing civil air defense door designs have significant defects. Once the door body is closed, if there are still people who fail to evacuate in time or firefighters need to enter the scene to carry out firefighting operations, it becomes extremely difficult to reopen and close the heavy-duty civil air defense door. At the same time, due to the heavy door body, the opening and closing operation takes a long time, and during the operation, flames may burst out from the door gap, causing the fire to spread further. Therefore, traditional civil air defense doors can no longer meet the current increasingly complex usage needs. Utility Model Content

[0032] See also Figure 1-6 As shown, the utility model provides a technical solution for a fire emergency escape civil air defense door: a fire emergency escape civil air defense door, comprising a main door body 1, a door opening 2 is opened on one side of the main door body 1, a quick passage mechanism 3 is movably installed inside the door opening 2, and closing components 4 are installed on both sides of the quick passage mechanism 3; the quick passage mechanism 3 comprises a motor 301, a sliding frame 303 and a slide bar 304, the motor 301 is installed in the installation cavity at the lower end of the main door body 1 through a bracket, and a gear shaft 302 is rotatably installed at the lower end of the door opening 2 by opening a mounting groove, the output end of the motor 301 is connected to the gear shaft 302, the sliding frame 303 is movably installed in the door opening 2, and the lower end surface of the sliding frame 303 is meshed with the gear shaft 302 by opening teeth, the slide bar 304 is symmetrically fixedly installed at the upper and lower ends of the sliding frame 303, and the slide bar 304 is slidably connected to the slide groove on the inner side of the door opening 2. When a fire occurs in a public place such as a shopping mall or a hospital, the crowd is evacuated quickly first, and then the staff closes the civil air defense door to prevent the fire from spreading, and controls the motor 301 and the gear shaft 302 to drive the sliding frame 303 to move, and moves the sliding frame 303 to the side where there is no fire, and blocks the door opening 2 through the side wall of the sliding frame 303. After the civil air defense door is closed, if some people are trapped due to slow movement and fail to leave the fire scene in time, the staff or the trapped people manually control the motor 301 control button on the main door body 1, and the motor 301 and the gear shaft 302 drive the sliding frame 303 to move to the side where there is no fire, and block the door opening 2 through the side wall of the sliding frame 303. The frame 303 moves to the side where the fire occurs. At this time, the trapped person can manually open the closing component 4 and stand in the sliding frame 303. Then, the control button on the door is used to control the motor 301 to reverse again and close the closing component 4. The reversed motor 301 drives the sliding frame 303 to move to the side without the fire until the side of the sliding frame 303 blocks the door opening 2 again. At this time, the trapped person opens the closing component 4 to leave the sliding frame 303 and escape. Later, the staff and firefighters can also enter or leave the fire scene through the sliding frame 303 to perform firefighting operations. Through the fast passage mechanism 3, the effect of transferring the trapped person out of the fire scene without opening the civil air defense door is achieved. It is quick and convenient. The trapped person can operate on his own inside the door, which increases the escape probability of the trapped person. In addition, the staff and firefighters can also enter and exit the fire scene more conveniently without opening the civil air defense door, ensuring the escape efficiency and rescue efficiency while effectively preventing the spread of fire caused by opening the civil air defense door.

[0033] The closing component 4 includes a permanent magnet 401 and a magnetic strip 402. The permanent magnet 401 is embedded and installed on both sides of the sliding frame 303. The magnetic strip 402 is installed on the inner side of the sliding frame 303 and is attracted to the permanent magnet 401. The upper and lower ends of the magnetic strip 402 are slidably connected to the guide grooves on the upper and lower sides of the sliding frame 303. A folding partition 403 is connected between the magnetic strips 402. When the trapped person, staff or firefighter needs to get on the sliding frame 303, first overcome the attraction of the permanent magnet 401 to remove the magnetic strip 402 on one side and move it to the magnetic strip 402 on the other side. During the movement of the magnetic strip 402, the folding partition 403 is folded and compressed until the person can get on the sliding frame 303. Then, the magnetic strip 402 is pulled in the opposite direction to be attracted to the permanent magnet 401 again, and the folding partition 403 is opened, and the sliding frame 303 is closed again. The closing component 4 can achieve the effect of closing both sides during the movement of the sliding frame 303, thereby preventing flames from escaping from the sliding frame 303 due to excessive fire when people pass through, thereby further improving the safety of people passing through.

[0034] The lower end of the sliding frame 303 is symmetrically installed with a pulley 5 through an angle code. When the main door body 1 of the civil defense door is opened and closed as a whole, or when the sliding frame 303 slides in the door opening 2, the pulley 5 can maintain the balance of both sides of the sliding frame 303 to prevent the sliding frame 303 from tilting.

[0035] The thickness of both sides of the sliding frame 303 is consistent with the thickness of the main door body 1. The consistent thickness can ensure that the overall thermal insulation performance and impact resistance of the civil air defense door are relatively balanced.

[0036] Limiting blocks 6 are installed on both sides of the slide bar 304 , and the limiting blocks 6 can prevent the sliding frame 303 from excessive displacement and thus detaching from the door opening 2 .

[0037] The folding partition 403 is made of stainless steel, which has the characteristics of corrosion resistance, high temperature resistance and high strength, and is more suitable for the special environment in which the civil air defense door is working.

[0038] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
