Description

Technical Field

[0001] This utility model belongs to the field of fire safety technology, specifically relating to a building floor fire monitoring device. Background Technology

[0002] Property fire protection refers to the organization, implementation, and supervision of fire protection work in property management, aiming to prevent fire accidents and ensure the safety of life and property of residents in the community.

[0003] However, in existing residential communities, residents' knowledge is linked to the effectiveness of fire protection. Fire doors on each floor are designed to be normally closed, resulting in relatively sealed corridors on each floor. This creates a conflict with residents' daily lives, leading to multiple instances of fire door damage and rendering the security system ineffective during a fire.

[0004] At the same time, due to the high number of buildings in the community, it is difficult to repair the fire protection system in a timely manner when it malfunctions, thus creating security gaps. Utility Model Content

[0005] The purpose of this utility model is to provide a building floor fire monitoring device that can independently monitor each floor from the existing fire protection system, thereby ensuring the safety of residents' property.

[0006] The specific technical solution adopted by this utility model is as follows:

[0007] A building floor fire monitoring device includes a corridor, a fire alarm installed on the top side of the corridor, a fire door installed in the security passage of the corridor, a fire vent installed in the ventilation outlet of the corridor, and an elevator shaft installed in the corridor. A monitoring device is installed in the corridor and is coupled to the fire alarm. A push rod is installed in the fire door and the fire vent, and the push rod is coupled to the monitoring device.

[0008] The push rod is used to drive the fire door to close and the fire vent to open in case of fire.

[0009] The push rod, monitoring device, and fire protection system operate in parallel.

[0010] A wireless signal transmitter is installed inside the elevator shaft. A smart switch is installed in parallel with the fan of the fire ventilation duct. The wireless signal transmitter is coupled to the monitoring device and the smart switch. The wireless signal transmitter is used to send an activation wireless signal to the smart switch.

[0011] The monitoring device is equipped with an independent power supply and a control circuit board. The independent power supply is used to drive the construction work coupled with the monitoring device and to drive the wake-up function of the control circuit board.

[0012] The fireproof door includes a door frame, a door panel is hinged to one side of the door frame, a door closer is provided at the top of the door panel and the door frame, a swing rod is fixedly connected at the hinge of the door closer and the door frame, the swing rod is rotatably connected to the door frame, an impact block is fixedly connected to the swing rod, and a push rod is provided at the corresponding position of the door frame and the impact block.

[0013] The fire vent includes an outer frame, and the air inlet of the outer frame is rotatably connected to multiple sealing plates. A synchronous transmission part is coupled to a transmission shaft on one side of the sealing plate, and a push rod is provided on one side of the synchronous transmission part.

[0014] One of the sealing plates has a drive shaft connected to a gear, and a rack is provided on one side of the gear. The rack and gear are coupled together, and a battery push rod is provided on one side of the rack.

[0015] The push rod includes an impact rod and a guide sleeve. The impact rod is slidably connected inside the guide sleeve. One end of the guide sleeve is provided with deflagration filler at the position corresponding to the impact rod. The end of the guide sleeve with deflagration filler is sealed and connected with a sealing sleeve. The sealing sleeve is provided with an ignition part at the position corresponding to the deflagration filler.

[0016] An elevator push rod is fixedly connected to the end of the ignition section away from the deflagration packing, and the driving part of the elevator push rod is fixedly connected to the ignition section.

[0017] The elevator push rod is threadedly connected to a safety part away from the triggering part, and a limit boss is provided at the end of the drive part of the elevator push rod near the safety part.

[0018] The impact rod and guide sleeve are provided with a limiting groove. A plastic ring and a bending limiting piece are provided in the limiting groove. Multiple equally distributed plastic rings are fixedly connected to the upper and lower sides of the plastic ring. The plastic ring is made of thin plastic and is sheared and broken by the interlaced limiting grooves under high pressure impact.

[0019] The technical effects achieved by this utility model are as follows:

[0020] This invention uses a push rod to impact the impact block, which in turn drives the swing rod to rotate, thereby controlling the door panel to deflect at a certain angle. With the cooperation of the door closer, the door panel is closed, allowing the fire door to remain open under normal circumstances. This reduces the impact on residents and ensures the safety of the door panel, enabling it to function effectively in a fire.

[0021] In this invention, when the monitoring device drives the wireless signal transmitter to work, the wireless signal transmitter sends a wireless signal, which is eventually transmitted to the intelligent switch receiver of the fan in the fire ventilation duct, thereby driving the intelligent switch to work and extracting the toxic smoke from the fire floor.

[0035] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0036] like Figures 1-11 As shown, a building floor fire monitoring device includes a corridor 1, a fire alarm 8 installed on the top side of the corridor 1, a fire door 3 installed in the security passage of the corridor 1, a fire vent 2 installed at the exhaust vent of the corridor 1, an elevator shaft 4 installed in the corridor 1, a monitoring device 7 installed in the corridor 1, the monitoring device 7 being coupled to the fire alarm 8, and a push rod 6 installed in the fire door 3 and the fire vent 2, the push rod 6 being coupled to the monitoring device 7;

[0037] The push rod 6 is used to drive the fire door 3 to close and the fire vent 2 to open in case of fire.

[0038] The push rod 6 and the monitoring device 7 operate in parallel with the fire protection system.

[0039] Furthermore, the preferred fire alarm 8 is a smoke detector, which has an independent emergency power supply.

[0040] Furthermore, the push rod 6 and the monitoring device 7 can still function normally when the fire protection system is not working.

[0041] Furthermore, the push rod 6 and the monitoring device 7 are connected to the fire protection system and work together, and can function normally when the fire protection system malfunctions.

[0042] A wireless signal transmitter 5 is installed in the elevator shaft 4. A smart switch is installed in parallel with the fan in the fire ventilation duct. The wireless signal transmitter 5 is coupled to the monitoring device 7 and the smart switch. The wireless signal transmitter 5 is used to send an activation wireless signal to the smart switch.

[0043] Furthermore, since the fans in fire ducts are often installed underground or on the roof, the signal is transmitted through an elevator shaft that connects the upper and lower floors to avoid the concrete partition blocking the signal.

[0044] Furthermore, smoke detectors and fire alarms can be installed in fire vents, so that fire alarms can still be issued immediately when the fire protection system malfunctions.

[0045] According to the above structure, when the monitoring device 7 drives the wireless signal transmitter 5 to work, the wireless signal transmitter 5 sends a wireless signal, which is eventually transmitted to the intelligent switch receiver of the fan in the fire ventilation duct, thereby driving the intelligent switch to work and extracting the toxic smoke from the fire floor.

[0046] See attached document Figure 1 The monitoring device 7 is equipped with an independent power supply and control circuit board. The independent power supply is used to drive the construction work coupled with the monitoring device 7 and to drive the wake-up function of the control circuit board.

[0047] Furthermore, the monitoring device 7 has two independent power supplies, one for maintaining the wake-up function of the control circuit board and the other for emergency use and driving the cannon push rod 6.

[0048] Furthermore, the power supply inside monitoring device 7 needs to be replaced periodically.

[0049] According to the above structure, when the fire alarm 8 detects a fire, it sends a fire signal to the central control and also sends an electrical signal to the monitoring device 7. This signal is used to activate the control circuit board inside the monitoring device 7. Through the cooperation of the control circuit board and the independent power supply, power is output to the fire door 3 and the fire vent 2 in sequence, and the push rod 6 is driven to work.

[0050] See attached document Figures 10-11 The fire door 3 includes a door frame 301, a door panel 302 is hinged to one side of the door frame 301, a door closer 303 is provided on the top of the door panel 302 and the door frame 301, a swing rod 9 is fixedly connected to the hinge of the door closer 303 and the door frame 301, the swing rod 9 is rotatably connected to the door frame 301, an impact block 10 is fixedly connected to the swing rod 9, and a push rod 6 is provided at the corresponding position of the door frame 301 and the impact block 10.

[0051] Furthermore, when the angle between the door frame 301 and the door panel 302 is less than 110 degrees, the door closer 303 keeps the fire door 3 closed.

[0052] When the angle between the door frame 301 and the door panel 302 is greater than 110 degrees, the door closer 303 keeps the fire door 3 in the open position.

[0053] Furthermore, the door closer 303 may be equipped with a drive device for remote control of the fire door 3 in the closed state by the fire protection system. This drive device is existing technology and will not be described in detail here.

[0054] Furthermore, when the door panel 302 is in the open state, the door panel 302 drags the door closer 303, causing the swing arm 9 to rotate and causing the impact block 10 to contact the drive part of the cannon push rod 6.

[0055] Furthermore, the cannon push rod 6 impacts the impact block 10, causing the swing rod 9 to rotate, thereby controlling the door panel 302 to deflect at a certain angle, and with the cooperation of the door closer 303, the door panel 302 is closed.

[0056] See attached document Figure 2 To be continued Figure 4 The fire vent 2 includes an outer frame 201. The air inlet of the outer frame 201 is rotatably connected to multiple sealing plates 202. A synchronous transmission part 204 is coupled to a transmission shaft on one side of the sealing plate 202. A push rod 6 is provided on one side of the synchronous transmission part 204.

[0057] One of the sealing plates 202 has a drive shaft connected to a gear 207. A rack 206 is provided on one side of the gear 207. The rack 206 and the gear 207 are coupled. A battery push rod 205 is provided on one side of the rack 206.

[0058] Furthermore, the synchronous transmission unit 204 is preferably a multi-link mechanism.

[0059] Furthermore, rack 206 is not normally engaged with gear 207, thereby preventing interference between the cannon push rod 6 and battery push rod 205 and rack 206 when the cannon push rod 6 is working alone.

[0060] Furthermore, fire vent 2 is normally kept closed to prevent insects from entering different floors through the ventilation duct.

[0061] Furthermore, by impacting the linkage of the synchronous transmission unit 204 with the push rod 6, the sealing plate 202 is rotated, causing the fire vent 2 to open.

[0062] According to the above structure, when the fire protection system receives a fire signal, it controls the battery push rod 205 to work and drive the rack 206 to move. Then, the rack 206 drives the gear 207 to rotate, and the synchronous transmission part 204 ensures that the sealing plate 202 rotates, thereby making the fire vent 2 open.

[0063] See attached document Figure 5 To be continued Figure 9The cannon push rod 6 includes an impact rod 601 and a guide sleeve 602. The impact rod 601 is slidably connected inside the guide sleeve 602. One end of the guide sleeve 602 is provided with a deflagration filler 604 at the position corresponding to the impact rod 601. The other end of the guide sleeve 602 with the deflagration filler 604 is sealed and connected with a sealing sleeve 612. The sealing sleeve 612 is provided with an ignition part 606 at the position corresponding to the deflagration filler 604.

[0064] An elevator push rod 607 is fixedly connected to one end of the ignition section 606 away from the deflagration packing 604, and the driving part of the elevator push rod 607 is fixedly connected to the ignition section 606.

[0065] The elevator push rod 607 has a safety part 608 connected to the threaded part away from the trigger part 606, and a limit boss is provided at the end of the drive part of the elevator push rod 607 near the safety part 608.

[0066] The impact rod 601 and the guide sleeve 602 are provided with a limiting groove 603. The limiting groove 603 is provided with a plastic ring 609 and a bending limiting piece 610. Multiple plastic rings 609 are fixedly connected to the upper and lower sides of the plastic ring 609. The plastic ring 609 is made of thin plastic and is sheared and broken by the interlaced limiting grooves 603 under high pressure impact.

[0067] Furthermore, the end of the impact rod 601 near the deflagration packing 604 is provided with a push rod part with a smaller diameter, which is used to increase the thrust on the impact rod 601 as a whole.

[0068] Furthermore, the filling material within the deflagration filler 604 undergoes combustion and explosion under the compression and / or friction of the ignition section 606.

[0069] Furthermore, under the action of the elevator push rod 607, the sharp end of the ignition part 606 is fully inserted into the deflagration packing 604, thereby ensuring that the kinetic energy generated by the explosion of the deflagration packing 604 is discharged from one side of the impact rod 601.

[0070] Furthermore, the plastic ring 609 and the bending limiting piece 610 are used to connect and fix the impact rod 601 and the guide sleeve 602.

[0071] Furthermore, during the installation of the push rod 6, in order to prevent the accidental deflagration of the deflagration packing 604, a safety part 608 is provided. By rotating the safety part 608, the drive end of the elevator push rod 607 is supported, preventing the drive part of the elevator push rod 607 from pushing the ignition part 606 into the deflagration packing 604.

[0072] Furthermore, the deflagration packing 604 is covered with a plastic shell 605, and the shell is thinner at the end of the deflagration packing 604 near the ignition part 606. The plastic shell 605 is used to ensure the safety of the deflagration packing 604.

[0073] Furthermore, the deflagration packing 604 is used to increase the driving force of the impact rod 601, thereby reducing the resistance caused by the obstructions accumulated at the shaft of the equipment.

[0074] Furthermore, the guide sleeve 602, sealing sleeve 612, and elevator push rod 607 are housed inside the protective outer sleeve 611, thereby facilitating overall installation and improving the overall safety of the push rod 6.

[0075] According to the above structure, by supplying power to the elevator push rod 607, the excitation part 606 is driven to insert into the deflagration packing 604, causing the deflagration packing 604 to explode, and the resulting directional impact force pushes the impact rod 601 to quickly strike the drive part.

[0076] The working principle of this utility model is as follows: When the fire alarm 8 detects a fire, it sends a fire signal to the central control and also sends an electrical signal to the monitoring device 7. This signal is used to activate the control circuit board inside the monitoring device 7. Through the cooperation of the control circuit board and the independent power supply, power is output to the fire door 3 and the fire vent 2 in sequence. By supplying power to the elevator push rod 607, the excitation part 606 is driven to insert into the deflagration filler 604, causing the deflagration filler 604 to explode. The directional impact force generated pushes the impact rod 601 to quickly hit the drive part, thereby closing the fire door 3 and opening the fire vent 2. At the same time, when the monitoring device 7 drives the wireless signal transmitter 5 to work, the wireless signal transmitter 5 sends a wireless signal, which is finally transmitted to the intelligent switch receiver of the fan in the fire duct, thereby driving the intelligent switch to work and extracting the toxic smoke from the fire floor.

[0077] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
