Smoke-proof fire door electric protection system and smoke-proof fire door

Abstract

This invention discloses an electric protection system for smoke and fireproof doors and a smoke and fireproof door, relating to the field of fire protection equipment. The electric protection system for smoke and fireproof doors uses a main control module to communicate and control the electrical components throughout the door. Based on the door's opening frequency and the presence of a fire, it adjusts the locking state of the door closer, the damping of the door opening and closing, and the door lock's closing state. This improves passage speed and reduces passage difficulty while ensuring fire safety, and also reduces wear and tear on the smoke and fireproof door. Furthermore, it automatically selects different demodulation cycles for fire and non-fire conditions. In the absence of a fire, it reduces the adjustment frequency to achieve energy savings, while in the presence of a fire, it increases the speed of door status changes, allowing for rapid adjustments when pedestrian traffic decreases. This reduces smoke entering escape routes, slows the spread of fire, and provides more effective protection for escape.

Description

Technical Field

[0001] This invention relates to the field of fire protection equipment, and in particular to an electric protection system for smoke and fireproof doors and smoke and fireproof doors. Background Technology

[0002] Smoke-proof and fireproof doors are a special door structure used in the fire protection field. They achieve flame retardancy and fire resistance through multi-layer composite materials. At the same time, a sealing strip is installed between the door body and the door frame. The sealing strip is mostly made of thermal expansion material, which expands at high temperatures, thereby achieving a smoke-proof effect. These smoke-proof and fireproof doors are usually installed in fire lanes to ensure that fire can be prevented from spreading to the fire lanes in the event of a fire.

[0003] Traditional smoke and fire doors are typically equipped with door closers to ensure stable closure and smoke and fire protection during a fire. Different types of door closers are used to keep the door open or closed. Regardless of whether it's normally open or normally closed, the smoke and fire door must meet two fire safety regulations when closing: one is that the door must be naturally closed to the door frame under the hydraulic action of the door closer; the other is that the door lock must remain locked in place to prevent airflow from forcing the door open. While this design provides excellent smoke and fire protection, in situations with high daily traffic or during escapes, the door lock remains locked, and the high hydraulic damping makes opening difficult. Once opened, the door closes quickly, affecting passage and escape speed. Furthermore, frequent opening and closing of the door reduces the lifespan of the door closer. Therefore, a smoke and fire door electric protection system and a smoke and fire door are provided. Summary of the Invention

The calculation period is T, and a period threshold is set in the main control module. and In the absence of a fire, T = This reduces the rate of change in the door's state, thereby decreasing the adjustment frequency and achieving energy savings. Additionally, in the event of a fire, T = This allows for faster changes in the door's status, enabling quick adjustments when foot traffic decreases.

Detailed Implementation

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Example 1: The present invention provides, as follows Figure 1 The illustrated electric protection system for smoke and fire doors includes: The main control module carries the main control program and is capable of transmitting and receiving signals. The monitoring module is used to monitor changes in the door's position and transmit the monitoring data to the monitoring center to calculate the door's opening and closing frequency within a cycle. ; The door closer locking module, door closer damping adjustment module, and door locking control module are all connected to the monitoring center control. Door closer locking module based on Control the door closer to a preset open / closed state; Door closer damping adjustment module Adjust the hydraulic damping coefficient of the door closer; Locking control module Control the door lock to a preset open / closed state.

[0021] The main control program is configured with a base The control logic for adjusting the door closer locking module, the door closer damping adjustment module, and the door locking control module includes: Preset threshold for the opening and closing frequency of the door within a cycle and , and then with Perform a comparison; like ≤ If the door closer locking module, door closer damping adjustment module, and door locking control module do not operate; like ≤ ≤ If the door closer locking module does not operate, the door closer damping adjustment module controls the door closer opening hydraulic damping to decrease, while the door closer closing hydraulic damping increases; in order to achieve fast opening and slow closing. like ≤ If the door closer locking module detects that the door is opened to its maximum state, the door closer will lock, so that the door remains open.

[0022] The main control module integrates a fire monitoring and alarm module, which is used to detect the presence of a fire; when ≤ ≤ hour; If there is no fire, the door lock control module will keep the door lock open. In the event of a fire, the door locking control module will not activate, requiring the door lock to be opened and closed via the handle.

[0023] make The calculation period is T, and a period threshold is set in the main control module. and ; If there is no fire, T = This slows down the rate at which the state of the gate changes. If a fire occurs, T = This increases the speed at which the state of the door changes.

[0024] Working principle: In this system, an intelligent control system is proposed based on existing smoke and fire doors. The main control module is designed to realize communication and control of the electrical components in the entire smoke and fire door. The system intelligently controls the entire smoke and fire door to make adaptive adjustments based on the door opening frequency and the presence of a fire. This improves passage speed, reduces passage difficulty, and reduces wear and tear on the smoke and fire door while ensuring fire safety. The system mainly includes two scenarios. The fire monitoring and alarm module detects whether a fire is currently present. If there is no fire, the module monitors the door opening frequency within a certain period T. Since there is no fire, a long period is used for T. This reduces the rate of adjustment and saves energy. If at this time ≤ If the door closer locking module, door closer damping adjustment module, and door locking control module do not activate, it indicates that the pedestrian flow at the fire door is very low, and no other auxiliary settings are required; normal passage is sufficient. like ≤ ≤ If the door closer locking module does not operate, the door closer damping adjustment module controls the door closer to reduce the opening hydraulic damping and increase the closing hydraulic damping. At the same time, the door closer lock control module controls the door lock to remain open to achieve fast opening and slow closing. This indicates that there are many people passing through the fire door, forming a continuous passage. At this time, by reducing the opening damping and keeping the door lock open, the passerby can open the door with a light push, thereby reducing the difficulty of passage, speeding up the passage, and also reducing the wear and tear on the door closer and door lock from repeated opening and closing. like ≤ When the monitoring module detects that the door is opened to its maximum state, the door closer locking module controls the door closer to lock, so that the door remains open. This indicates that the flow of people has basically reached the maximum capacity of the entire passage. At this time, the door closer locks the door at its maximum opening, so that subsequent people can pass through without pushing the door, further accelerating the passage of people, while avoiding the door closing automatically and causing injury to pedestrians. The above control design is based on actively adjusting the status of smoke and fire doors according to different traffic flows in the absence of a fire, thereby reducing the wear and tear on smoke and fire doors and ancillary facilities while ensuring passage.

[0025] Secondly, if the fire monitoring and alarm module detects a fire, it can issue a fire alarm and execute the following controls simultaneously; First, the dynamic adjustment period T of the entire smoke and fireproof door at this time is... The control strategy for smoke and fire doors needs to be adjusted quickly within a very short period of time. like ≤ If the door closer locking module, door closer damping adjustment module and door locking control module do not operate, it means that there are few people in the fire area and there will be no trampling or crowding. The escapees will reach the smoke and fire door in the normal escape method, open the smoke and fire door by rotating the handle, and then push the smoke and fire door open to escape. like ≤ ≤ If the door closer locking module does not activate, the door closer damping adjustment module controls the door closer to reduce the opening hydraulic damping and increase the closing hydraulic damping; and the door locking control module does not activate, so the door lock needs to be opened and closed by the handle. This indicates that there are many people in the fire area and people need to evacuate quickly. At this time, by reducing the opening damping of the door closer and increasing the closing damping, the door can be easily pushed open and then slowly lowered. If people are concentrated at this time, the next person can pass through before the door is closed, thereby improving the escape speed. The door lock is in a normal closing state, so that if people do not pass through continuously, the door will automatically close to prevent the high pressure of smoke and fire from pushing the door open and causing smoke to enter the escape route, thereby slowing down the spread of fire. like ≤ When the monitoring module detects that the door is fully open, the door closer locking module controls the door closer to lock, keeping the door open. This indicates that the entire fire area is very congested and people need to evacuate quickly. To avoid overcrowding and trampling, and to prevent further congestion, keeping the fire door open and locked allows people to leave quickly. Meanwhile, due to the period T= At this point, once the number of people decreases, it returns to normal. ≤ ≤ When the door is in a certain state, the door closer locking module will react immediately, so that the door can close automatically. This will prevent the door from being in a large-angle open state when the flow of people decreases, which would cause airflow and smoke to enter the escape passage, thus effectively preventing the fire from spreading inward.

[0026] In the event of a fire, this control strategy prioritizes ensuring the passage of people. The smoke and fire doors are dynamically adjusted according to different pedestrian traffic levels to ensure that people can escape quickly and smoothly through the smoke and fire doors. At the same time, by shortening the adjustment cycle, the system can be adjusted quickly when pedestrian traffic decreases, thereby reducing the amount of smoke entering the escape route, slowing the spread of fire, and providing more effective protection for escape.

[0027] Example 2, as follows Figures 2 to 10 As shown, a smoke and fireproof door includes an electric protection system for the smoke and fireproof door, a door frame 1, and two composite fireproof doors 2 rotatably disposed in the door frame 1. A sequencer 3 is fixedly installed on one side of the door frame 1, and an electric door closer 6 is installed between the other side of the door frame 1 and the two composite fireproof doors 2, respectively.

[0028] The electric door closer 6 includes an electric lock box 61 fixedly installed on the door frame 1 and a hydraulic box 62 fixedly installed on the composite fire door 2. A connecting rod 63 is installed between the electric lock box 61 and the hydraulic box 62.

[0029] The electric lock box 61 includes a linear box body 611 and a perforated lock plate 612 fixedly installed at the top of the linear box body 611. A sliding groove 614 is provided on the inner wall of the linear box body 611. A sliding member 613 is slidably installed on the sliding groove 614.

The end of the rotary push rod 6110 is located between the two sets of baffles 6111, so that when the rotary push rod 6110 rotates, it pushes the L-shaped sliding bar 617 to slide up or down through the baffles 6111. The sliding member 613 has a locating pin 6112 inside, and the outer wall of the L-shaped sliding strip 617 has two locating holes 6114 that are adapted to the locating pin 6112. The back of the locating pin 6112 is provided with a locking spring 6113.

[0030] The hydraulic box 62 includes a sealed chamber 621 and a rotating shaft 622 rotatably disposed in the sealed chamber 621. The top end of the rotating shaft 622 is rotatably connected to the connecting rod 63. A hydraulic column 623 is slidably disposed in the sealed chamber 621. The hydraulic column 623 divides the interior of the two ends of the sealed chamber 621 into two independent chambers. The hydraulic column 623 is provided with a toothed groove. A gear adapted to the toothed groove is fixedly installed on the outer wall of the rotating shaft 622. A return spring 624 is provided in one set of independent chambers. Two independent chambers are respectively provided with hydraulic oil channels 625 between them and the tooth groove. A door closer damping adjustment module is installed in the two hydraulic oil channels 625. The door closer damping adjustment module includes an adjustment plug 626 threadedly connected in the hydraulic oil channel 625. An adjustment motor 627 is fixedly installed on the outer wall of the sealed chamber 621. An external hexagonal shaft 628 is fixedly connected to the output end of the adjustment motor 627. The external hexagonal shaft 628 is movably inserted into the adjustment plug 626 to drive the adjustment plug 626 to move up and down, thereby changing the flow rate of the hydraulic oil channel 625.

[0031] The door lock 7 includes a lock box body 71 and a bolt 74 slidably disposed inside the lock box body 71. A lock head 72 is fixedly connected to the outer end of the bolt 74. A locking control module is provided at the other end of the bolt 74. The locking control module is an electromagnet 76. The electromagnet 76 is fixedly connected to the inner side wall of the lock box body 71. A memory spring 75 is movably sleeved on the outer surface of the bolt 74. A rotating head 73 is rotatably disposed on the lock box body 71. A door handle 5 is installed in the rotating head 73. The rotating head 73 rotates to push the bolt 74 to move towards the end closer to the electromagnet 76.

[0032] Working principle: This smoke and fire door is a further adaptive modification based on the traditional normally closed smoke and fire door, in order to realize the electric protection system of the smoke and fire door; In this solution, an electric door closer 6 is designed, and an infrared distance sensor 616 is installed on one side of the sliding member 613. The infrared distance sensor 616 determines the current door opening angle to control whether the door is normally open or normally closed. At the same time, the infrared distance sensor 616 judges the occurrence of the door "opening action" by the change in value. By recording the number of "opening actions" within a preset time, the opening frequency of the smoke and fire door is obtained as an important input parameter. At the same time, smoke sensors and temperature sensors are used to judge the occurrence of fire, and adaptive adjustments are made based on the two input parameters. When the door needs to be locked in a normally open state, the servo rotary motor 619 rotates counterclockwise, causing the rotary push rod 6110 to push the upper stop bar 6111 to slide upward, thereby causing the positioning pin 618 to move upward and insert into the perforated lock plate 612. At the same time, the L-shaped sliding bar 617 slides upward, causing the end of the positioning pin 6112 to enter the lower positioning hole 6114. Under the action of the locking spring 6113, the height of the L-shaped sliding bar 617 is maintained, thereby locking the connecting rod 63 and keeping the door in a normally open state. Then the servo rotary motor 619 rotates clockwise to reset. When the door needs to be automatically closed, the servo rotary motor 619 rotates clockwise, causing the positioning rod 618 to move out of the perforated lock plate 612. At the same time, the L-shaped sliding bar 617 moves down, and the positioning pin 6112 moves out of the upper positioning hole 6114 and into the lower positioning hole 6114. The locking state can also be adjusted by manually pushing and pulling the bottom end of the L-shaped sliding bar 617. When the door can automatically close, during periods of high pedestrian traffic, the two regulating motors 627 are controlled to rotate. One regulating motor 627 near the return spring 627 rotates clockwise, while the other rotating counterclockwise. This causes the regulating plug 626 near the return spring 624 to spiral upwards in the hydraulic oil channel 625, increasing the opening degree of the hydraulic oil channel 625. This reduces the door opening resistance, making it easier for pedestrians to push the door open. Simultaneously, the other regulating plug 626 spirals downwards in the hydraulic oil channel 625, decreasing the opening degree of the hydraulic oil channel 625. This increases the door closing resistance, allowing more people to pass through after a single opening, preventing pedestrians from being pinched, and facilitating pedestrian passage. Secondly, when there is a large flow of people and no fire, the electromagnet 76 is activated. When the first pedestrian rotates the handle 5, the rotating head 73 moves the bolt 74 inward to unlock the door. The electromagnet 76 then magnetically holds the end of the bolt 74 in place. When subsequent people pass through, even if the door is closed, there is no need to rotate the handle 5. Or, if the number of people is uncertain, rotating the handle 5 will not cause any resistance, thus speeding up pedestrian passage and reducing wear caused by frequent rotation of the door lock.
