Description

Technical Field

[0001] This utility model relates to the field of fire safety technology, and in particular to a clean fire door device with multiple functions. Background Technology

[0002] In places with extremely high requirements for environmental cleanliness and fire safety, such as medical cleanrooms, biological laboratories, and precision electronics workshops, fire doors serve as crucial safety barriers and environmental isolation facilities, and their performance directly affects the safety protection and cleanliness maintenance of these locations. These places not only require fire doors to have reliable fireproof and heat insulation performance, but also to meet strict sealing requirements to prevent the spread of pollutants and maintain stable indoor pressure differentials. Furthermore, in the event of a sudden fire or environmental anomaly, they must possess rapid response and intelligent linkage capabilities to ensure personnel evacuation and environmental safety.

[0003] Traditional fire doors often use fixed rubber strips for sealing, resulting in a loose fit between the door panel and the frame. Gaps can easily appear due to installation errors or deformation from long-term use, leading to damage to the clean environment and smoke leakage. While fixed thresholds can improve sealing, they can also obstruct passage and create many cleaning dead spots, making it difficult to meet the hygiene requirements of clean environments. Threshold-less designs sacrifice sealing performance and cannot effectively isolate the environment. They also lack real-time monitoring of environmental parameters (temperature, humidity, smoke) and door panel status (closure degree, sealing pressure), and cannot automatically warn of fire hazards or abnormal cleanliness. Utility Model Content

[0004] The main purpose of this utility model is to provide a cleanroom fireproof door device and a pet water dispenser with multiple functions. It aims to solve the problems of existing fireproof doors, which mostly use fixed rubber strips for sealing. The door panel and door frame are not tightly fitted, and gaps are easily formed due to installation errors or deformation after long-term use, resulting in damage to the clean environment and smoke leakage. Fixed thresholds can easily cause passage obstacles and have many cleaning dead corners, making it difficult to meet the hygiene requirements of clean places. Threshold-less designs sacrifice sealing performance and cannot effectively isolate the environment. At the same time, there is a lack of real-time monitoring of environmental parameters (temperature, humidity, smoke) and door panel status (closure degree, sealing pressure), and no automatic warning can be given when there is a fire hazard or abnormal cleanliness.

[0005] To achieve the above objectives, this utility model proposes a cleanroom fireproof door device with multiple functions, including a door frame and a door panel, wherein a dynamic sealing component and an intelligent control component are provided between the door frame and the door panel.

[0006] The dynamic sealing assembly includes an edge seal, a folding groove, a door sill strip, a fixing plate, a reduction gearbox, a drive motor, a mounting groove, several magnetic blocks, a magnetic fixing frame, a sealing strip, a first mating surface, and a second mating surface. The edge seal is fixedly connected to the inside of the door frame. The folding groove is located at the bottom of the inside of the door frame. The door sill strip is rotatably connected to the inside of the folding groove. The fixing plate is fixedly installed on one side of the door frame. The reduction gearbox is fixedly installed on one side of the fixing plate. The drive motor is fixedly installed on the top of the reduction gearbox. The mounting groove is located on one side of the door panel. Several magnetic blocks are fixedly installed inside the mounting groove. The magnetic fixing frame is located inside the mounting groove. The sealing strip is fixedly connected to one side of the magnetic fixing frame. The first mating surface is located on one side of both ends of the door sill strip. The second mating surface is located on one side of the bottom of the edge seal.

[0007] Furthermore, the size of the door panel matches the size of the inner side of the door frame, and one side of the door panel is rotatably connected to the inner side of the door frame.

[0008] Furthermore, the shape of the folding groove matches the shape of the sill strip, the output end of the reduction gearbox is connected to the rotating shaft of the sill strip, and the drive motor drives the sill strip to rotate within the folding groove through the reduction gearbox.

[0009] Furthermore, several magnetic blocks are evenly distributed along the inner side of the mounting groove, and the magnetic fixing frame is magnetically connected to the magnetic blocks. The side of the sealing strip away from the magnetic fixing frame is tightly fitted with the sealing edge.

[0010] Furthermore, the first mating surface and the second mating surface are fitted together, and a sealing gasket is provided between them.

[0011] Furthermore, the sealing strip is made of fire-resistant expanding sealing material, and its cross-section is stepped or arc-shaped. The sealing strip and the magnetic fixing frame are integrally formed.

[0012] Furthermore, the door panel is filled with nano-level fireproof and heat-insulating materials and an antibacterial coating, and the exterior of the door panel is made of stainless steel.

[0013] Furthermore, the intelligent control component includes a temperature and humidity sensor, a smoke sensor, a pressure sensor, a PLC controller, and a smart door lock. The temperature and humidity sensor, the smoke sensor, and the pressure sensor are fixedly installed on both sides of the door panel, the PLC controller is fixedly installed inside the door panel, and the smart door lock is fixedly installed on one side of the door panel.

[0014] Furthermore, the temperature and humidity sensor, smoke sensor, and pressure sensor are all electrically connected to the PLC controller.

[0015] Furthermore, the PLC controller is electrically connected to the drive motor and the smart door lock respectively, and realizes signal interaction.

[0016] Beneficial effects: This utility model discloses a multi-functional cleanroom fireproof door device. The dynamic sealing component uses a magnetic connection between a magnetic fixing frame and a magnetic block to drive the sealing strip to fit tightly against the sealing edge. Combined with a sealing gasket between the first and second mating surfaces, this forms a multi-layered sealing structure, effectively eliminating gaps to block pollutants and smoke. A drive motor, via a reduction gearbox, drives the door sill strip to rotate adaptively within a folding groove. When closed, it rotates out to seal; when open, it retracts to avoid obstacles, balancing sealing and ease of passage. An intelligent control component uses temperature, humidity, smoke, and pressure sensors to comprehensively monitor environmental parameters and the door's closure status on both sides, accurately detecting fire hazards and abnormal cleanliness. A PLC controller, as the core, receives and automatically analyzes sensor data. Upon detecting an anomaly, it quickly triggers the intelligent door lock to automatically unlock and the drive motor to retract the door sill strip, ensuring efficient emergency evacuation.

The edge seal 301 is fixedly connected to the inside of the door frame 1. The folding groove 302 is formed at the bottom of the inside of the door frame 1. The door sill strip 303 is rotatably connected to the inside of the folding groove 302. The fixing plate 304 is fixedly mounted. Mounted on one side of door frame 1, a reduction gearbox 305 is fixedly mounted on one side of fixing plate 304, a drive motor 306 is fixedly mounted on the top of reduction gearbox 305, a mounting groove 307 is opened on one side of door panel 2, several magnetic blocks 308 are fixedly mounted inside the mounting groove 307, a magnetic fixing frame 309 is located inside the mounting groove 307, a sealing strip 310 is fixedly connected to one side of the magnetic fixing frame 309, a first mating surface 311 is opened on one side of both ends of the threshold strip 303, and a second mating surface 312 is opened on... On one side of the bottom edge banding 301, the size of the door panel 2 matches the inner size of the door frame 1, and one side of the door panel 2 is rotatably connected to the inner side of the door frame 1. The shape of the folding groove 302 matches the shape of the threshold strip 303. The output end of the reduction gearbox 305 is connected to the rotating shaft of the threshold strip 303. The drive motor 306 drives the threshold strip 303 to rotate in the folding groove 302 through the reduction gearbox 305. Several magnetic blocks 308 are evenly distributed along the inner side of the mounting groove 307, and the magnetic fixing frame 309 is connected to the magnetic blocks 308. 08 Magnetic connection, the side of the sealing strip 310 away from the magnetic fixing frame 309 is tightly fitted with the sealing edge 301, the first mating surface 311 and the second mating surface 312 are fitted together, and a sealing gasket is provided between them. The sealing strip 310 is made of fireproof expansion sealing material, and its cross-section is stepped or arc-shaped. The sealing strip 310 and the magnetic fixing frame 309 are integrally formed. The door panel 2 is filled with nano-level fireproof and heat-insulating material and antibacterial coating, and the door panel 2 is made of stainless steel plate. The magnetic attraction strength of the magnetic block 308 is set to 5-8N to ensure that the magnetic fixing frame 309 drives the sealing strip 310 and the sealing edge 301 to form a stable bonding pressure, while avoiding excessive magnetic attraction that would cause excessive opening resistance of the door panel 2; the sealing gasket is made of high-temperature resistant silicone rubber with a thickness of 2-3mm, and its temperature resistance range can reach -60℃~260℃, which is suitable for disinfection in clean places and high-temperature environments during fires.

[0024] This embodiment achieves multi-layered synergistic sealing of the dynamic sealing assembly. Through the combination of magnetic sealing, mating surface sealing gasket, and fire-resistant expansion sealing strip 310, the sealing gap between the door panel 2 and the door frame 1 is controlled within 0.1mm, improving the sealing performance by more than 60% compared to the traditional fixed rubber strip sealing method. It also solves the problem of passage obstruction caused by fixed thresholds. A folding groove 302 is provided on the bottom inner side of the door frame 1, the shape of which perfectly matches the shape of the threshold strip 303, ensuring that the threshold strip 303 can be completely retracted into the groove. The threshold strip 303 is connected to the inside of the folding groove 302 via a rotating shaft. A fixing plate 304 is fixedly installed on one side of the door frame 1, and a reduction gearbox 305 is fixedly installed on the fixing plate 304. The drive motor 306 is fixed to the top of the reduction gearbox 305, and the output end of the reduction gearbox 305 is connected to the rotating shaft of the threshold strip 303.

A sealing gasket layer (such as a high-temperature resistant silicone gasket) is provided between the first mating surface 311 and the second mating surface 312 to further block the bottom gap and form a complete sealing structure. When door panel 2 is opened, drive motor 306 reverses, and sill strip 303 retracts into folding groove 302, avoiding obstruction of passage and reducing cleaning dead corners.

[0025] Optionally, the magnetic block 308 can be made of neodymium iron boron strong magnetic material, and its surface is electroplated for rust prevention to extend its service life in clean and humid environments; the sill strip 303 can be coated with polytetrafluoroethylene to reduce frictional resistance during cleaning and reduce cleaning dead corner residue.

[0026] In one embodiment, the intelligent control component includes a temperature and humidity sensor 401, a smoke sensor 402, a pressure sensor 403, a PLC controller 404, and a smart door lock 405. The temperature and humidity sensor 401, the smoke sensor 402, and the pressure sensor 403 are fixedly installed on both sides of the door panel 2. The PLC controller 404 is fixedly installed inside the door panel 2. The smart door lock 405 is fixedly installed on one side of the door panel 2. The temperature and humidity sensor 401, the smoke sensor 402, and the pressure sensor 403 are all electrically connected to the PLC controller 404. The PLC controller 404 is electrically connected to the drive motor 306 and the smart door lock 405 respectively and realizes signal interaction.

[0028] This embodiment realizes real-time monitoring and automatic linkage of the environment and door panel status by intelligent control components. Through sensor data and logical operations of PLC controller 404, the response time to fire hazards is shortened to less than 2 seconds, and the accuracy rate of cleanliness abnormality warning is improved to 98%. It solves the defects of traditional fire doors that lack intelligent monitoring and automatic response. When it is necessary to open door panel 2, the user inputs a command (such as swiping a card, password or biometric identification) through smart door lock 405. After receiving the unlock signal, PLC controller 404 controls drive motor 306 to reverse and retract threshold strip 303 into folding groove 302. At this time, rotating the door handle opens the door. At the same time, temperature and humidity sensor 401, smoke sensor 402 and pressure sensor 403 comprehensively monitor the environmental parameters and closing status on both sides of the door panel, accurately detect fire hazards and cleanliness abnormalities. PLC controller 404, as the core, receives sensor data and automatically analyzes it. When an abnormality is detected, it quickly triggers smart door lock 405 to unlock automatically and drive motor 306 to control threshold strip 303 to retract, ensuring emergency evacuation efficiency.

[0029] Optionally, the PLC controller 404 can be equipped with a wireless communication module (such as WiFi) to realize data interaction with the remote monitoring platform, and support managers to remotely view the status and abnormal alarm information of the fire door monitored by the intelligent control component; the smart door lock 405 can integrate three unlocking methods: fingerprint, password and card swipe, to adapt to the access management needs of different clean places.

[0030] Description: The dynamic sealing component and the intelligent control component work together to form a closed-loop system of "sealing-monitoring-response". The dynamic sealing component achieves basic sealing function through magnetic attraction and adaptive threshold, while the fire-resistant expansion sealing strip 310 and the door panel 2 material enhance fire resistance, heat insulation and cleanliness maintenance capabilities. The intelligent control component collects data through multiple sensors, which are then linked with the actuators via the PLC controller 404. It automatically adjusts when the sealing is abnormal and enables rapid evacuation in case of fire hazards, thus realizing the core value of the composite functional clean fire door.
