Description

Technical Field

[0001] This utility model relates to the field of fire door technology, specifically a fire door with strong impact resistance. Background Technology

[0002] Fire doors are doors that can meet the requirements of fire resistance stability, integrity and heat insulation within a certain period of time. They are fire-resistant partitions with a certain degree of fire resistance installed in fire compartments, evacuation stairwells, vertical shafts and other similar spaces. They are specifically used in buildings to isolate fire sources. Currently, existing fire doors lack active cooling and protection structures. When flames erode the door panel for a long time, the door panel temperature will rise rapidly, thus accelerating its own damage.

[0003] As disclosed in the prior art, Chinese utility model publication CN215408320U discloses a fire door with an external impact-resistant and deformation-resistant structure. This utility model includes a door frame, a fire door at the front end of the door frame, a transparent plate installed above the front end of the fire door, a fixed frame at the lower front end of the fire door, and an impact-resistant inner core inside the fixed frame. The impact-resistant inner core contains protective components. In the above structure, the impact-resistant inner core and protective components enhance the impact resistance of the fire door, but no related cooling protection structure is provided. Under the continuous action of a fire, the fire door will still be damaged more quickly due to the high temperature. That is, the problem of easy damage to the door panel due to the lack of an active cooling protection structure mentioned above exists. Therefore, we need to propose a fire door with strong impact resistance. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 This utility model provides a technical solution:

[0023] A fire door with strong impact protection includes: a door frame 1, and two sets of fire door bodies 2 are hinged inside the door frame 1; a fixing seat 3, which is fixedly installed on the top of the door frame 1; a cooling protection mechanism 4 for cooling and protecting both sides of the fire door body 2, and the cooling protection mechanism 4 is disposed inside the fixing seat 3; the cooling protection mechanism 4 includes a spray assembly 41 and an exhaust assembly 42, both of which are disposed at the bottom of the fixing seat 3.

[0024] The door frame 1 and the two sets of hinged fire door bodies 2 form a stable structure, which improves the overall impact resistance performance. The cooling protection mechanism 4 in the fixing seat 3 integrates the spray assembly 41 and the air extraction assembly 42, which can simultaneously provide active cooling protection for both sides of the fire door body 2. The synergistic effect of the two effectively solves the problem that traditional fire doors are easily damaged by high temperatures due to the lack of an active cooling structure, and enhances the reliability and service life of fire doors in fire protection.

[0025] Specifically, the spray assembly 41 includes a water pump 411, an inlet pipe 412, an outlet pipe 413, two sets of flow pipes 414, two sets of flow boxes 415, and multiple sets of nozzles 416. The water pump 411 is fixedly installed inside the mounting base 3. The inlet pipe 412 is connected to the inlet end of the water pump 411, and the outlet pipe 413 is connected to the outlet end of the water pump 411. The end of the outlet pipe 413 away from the water pump 411 is connected to the two sets of flow pipes 414. The bottom ends of the two sets of flow pipes 414 pass through the mounting base 3 and are respectively connected to the top of the two sets of flow boxes 415. The bottom of the two sets of flow boxes 415 is respectively connected to multiple sets of nozzles 416 arranged at equal intervals.

[0026] Through the coordinated arrangement of water pump 411, inlet pipe 412, outlet pipe 413, two-way diversion pipes 414, two-way diversion boxes 415, and multiple sets of sprinklers 416, the water pump 411 is fixed inside the mounting base 3. Together with the inlet pipe 412, outlet pipe 413, diversion pipes 414, diversion boxes 415, and sprinklers 416, it forms a complete water flow delivery path, which can stably draw and deliver water, ensuring that the cooling water can smoothly reach both sides of the fire door body 2. Among them, the two-way diversion pipes 414 and the two-way diversion boxes 415 cooperate to divide the water flow. The water is directed to both sides of the door, and combined with multiple sets of equally spaced nozzles 416 at the bottom of the diversion box 415, the water can be sprayed evenly on both sides of the door surface, avoiding insufficient local cooling and achieving full coverage of the door. This improves the uniformity and comprehensiveness of the cooling effect, effectively alleviates the problem of door temperature rise caused by long-term flame erosion, and slows down the damage rate of the door. At the same time, the water inlet pipe 412 can be connected to the sprinkler fire water pipe inside the building, which facilitates the access to a stable water source and ensures the continuous and effective operation of the sprinkler cooling function.

[0027] The tops of the two flow boxes 415 are fixedly installed at the bottom of the mounting base 3, and the two flow boxes 415 are located on both sides of the protective door.

[0028] By fixing the two-part distribution box 415 to the bottom of the mounting base 3 and placing it on both sides of the protective door, the installation stability of the spray structure is ensured, and the spray can be accurately aimed at both sides of the fire door body 2 for cooling. This avoids the cooling dead angle caused by the spray position deviation, and further improves the pertinence and reliability of the cooling protection.

[0029] In a further preferred embodiment, the air extraction assembly 42 includes an air extraction pump 421, an air extraction pipe 422, a smoke exhaust pipe 423, two sets of U-shaped pipes 424, four sets of air extraction boxes 425, and multiple sets of air inlet pipes 426. The air extraction pump 421 is fixedly installed in the inner bottom of the fixed base 3, and the air inlet end of the air extraction pump 421 is connected to the air extraction pipe 422. The two ends of the air extraction pipe 422 away from the air extraction pump 421 are respectively connected to the U-shaped pipes 424. The two ends of the two sets of U-shaped pipes 424 away from the air extraction pipe 422 are respectively connected to the top of the four sets of air extraction boxes 425. The side of the four sets of air extraction boxes 425 near the fire door is respectively connected to multiple sets of air inlet pipes 426. The smoke exhaust pipe 423 is connected to the air outlet end of the air extraction pump 421.

[0030] With the installation of an air pump 421, an air extraction pipe 422, a smoke exhaust pipe 423, two sets of U-shaped pipes 424, four sets of air extraction boxes 425, and multiple sets of air inlet pipes 426, the air pump 421 is fixed to the bottom of the mounting base 3. The air extraction pipe 422, U-shaped pipes 424, air extraction boxes 425, and air inlet pipes 426 form a complete smoke extraction path, stably achieving the extraction and discharge of high-temperature smoke around the fire door, ensuring timely reduction of high-temperature smoke accumulation around the door. The cooperation of the two sets of U-shaped pipes 424 and the four sets of air extraction boxes 425 can... The extraction range covers both sides of the fire door. Combined with the multiple sets of air inlet pipes 426 on the extraction box 425, high-temperature smoke can be extracted from multiple locations simultaneously, expanding the range of smoke collection, improving extraction efficiency, and avoiding excessively high local temperatures on the door caused by local smoke retention. At the same time, the exhaust pipe 423 can smoothly discharge the extracted high-temperature smoke to the outside (such as by connecting to the building's exhaust pipe 423), further reducing the temperature of the environment where the door is located, helping to enhance the protective performance of the fire door, and delaying damage to the door caused by high-temperature corrosion.

[0031] Specifically, four sets of air extraction boxes 425 are fixedly installed on both sides of the door frame 1, and multiple sets of air intake pipes 426 are arranged at equal intervals.

[0032] By fixing four sets of air extraction boxes 425 to both sides of the door frame 1 and setting the air inlet pipes 426 at equal intervals, the installation stability of the air extraction structure is ensured, and the high-temperature flue gas in various areas around the door can be collected evenly, avoiding local overheating of the door caused by the accumulation of local flue gas, thus improving the overall effectiveness of air extraction and cooling.

[0033] Each of the multiple intake pipes 426 has a filter screen 5 installed inside.

[0034] By setting the filter screen 5, the filter screen 5 in the air inlet pipe 426 can effectively block impurities from entering the air extraction component 42, prevent the pipe or pump body from being blocked, ensure the long-term stable operation of the air extraction system, reduce the risk of equipment failure, and extend the service life of the air extraction component 42.

[0035] Specifically, two sets of fixing blocks 6 are fixedly installed on the outside of the air extraction pipe 422, and both sets of fixing blocks 6 are fixedly installed on the inner top of the fixing base 3.

[0036] With the setting of the fixing block 6, the fixing block 6 on the outside of the air extraction pipe 422 is firmly installed in the top of the fixing base 3, which avoids the displacement or damage of the air extraction pipe 422 caused by equipment vibration during the air extraction process, ensures the stability of the air extraction path, and ensures that the air extraction function is continuously effective.

[0037] The outer side of the air extraction pipe 422 is equipped with a first solenoid valve 7, and the outer side of the water outlet pipe 413 is equipped with a second solenoid valve 8.

[0038] With the setting of the first solenoid valve 7 and the second solenoid valve 8, the first solenoid valve 7 on the air extraction pipe 422 and the second solenoid valve 8 on the water outlet pipe 413 can respectively control the start and stop of the air extraction assembly 42 and the sprinkler assembly 41, realizing the independent operation and coordinated work of the two. When the smoke sensor next to the fire door body 2 detects fire smoke, it can simultaneously start the water pump 411 and the air extraction pump 421 and open the two solenoid valves, so that the air extraction assembly 42 and the sprinkler assembly 41 can respond in time and work together to ensure that the cooling protection function is quickly activated when a fire occurs, and ensure that the cooling protection mechanism plays an efficient and accurate role in the fire scene, further enhancing the emergency protection performance of the fire door. Among them, the start and stop control of the water pump 411, the air extraction pump 421 and the two solenoid valves by the smoke sensor is existing technology, which will not be described in detail here.

[0039] Working principle: When this utility model is used, in the event of a fire, the cooling and protection mechanism 4 is activated to protect the fire door body 2. The water inlet pipe 412 of the sprinkler assembly 41 can be connected to the sprinkler fire water pipe inside the building. At this time, the water pump 411 is activated and the second solenoid valve 8 is opened. The water pump 411 draws water through the water inlet pipe 412. The water flows through the water outlet pipe 413 to the two diversion pipes 414, and then is introduced into the corresponding diversion box 415 through the diversion pipes 414. Finally, the water is evenly sprayed on both sides of the fire door body 2 through the multiple sets of nozzles 416 at the bottom of the diversion box 415, so as to achieve spray cooling of the door body and prevent it from being damaged by high temperature.

[0040] Simultaneously, the extraction assembly 42 operates synchronously, the extraction pump 421 starts and the first solenoid valve 7 opens. The extraction pump 421 extracts the gas from the four extraction boxes 425 through the extraction pipe 422 and two sets of U-shaped pipes 424, causing the high-temperature smoke around the fire door body 2 to be sucked in through the multiple sets of air inlet pipes 426 on the extraction box 425, and then discharged to the outside through the exhaust pipe 423 connected to the building's exhaust pipe 423. This process can reduce the accumulation of high-temperature smoke around the door body, help reduce the temperature of the environment where the fire door body 2 is located, and effectively improve the fire protection performance and service life of the fire door body 2 in a fire.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
