[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0020] In order to solve the technical problem that the existing fire door body 1 can only prevent fire through the material combination of the door body itself, does not have an active fire extinguishing function, and thus cannot prevent the spread of fire, and the fire prevention effect is insufficient, please refer to Figure 1-Figure 4 , this embodiment provides the following technical solutions:
[0021] A fire door with a fire extinguishing function comprises a fire door body 1, a water tank 2, a water spray pipe 3 and a smoke alarm 4. The smoke alarm 4 for monitoring fire is installed above the fire door body 1. The water tank 2 for storing fire extinguishing resources is also installed above the fire door body 1. A water spray pipe 3 for spraying the fire extinguishing resources in the water tank 2 is arranged directly above the water tank 2. A connecting pipe 22 is provided on the water tank 2, and the water tank 2 is connected to the water spray pipe 3 through the connecting pipe 22.
[0022] The fire door body 1 is provided with an outer layer 11, a first fireproof layer 12 and a second fireproof layer 13 from the outside to the inside. The inner surface of the outer layer 11 is tightly connected to the outer surface of the first fireproof layer 12, and the inner surface of the first fireproof layer 12 is tightly connected to the outer surface of the second fireproof layer 13. The outer layer 11 is made of steel, the first fireproof layer 12 is made of perlite board, and the second fireproof layer 13 is asbestos filler.
[0023] Specifically, the outer layer 11 of the fire door body 1 is made of steel, and the steel can be made of stainless steel. Using steel as the outer layer 11 of the fire door body 1 can make the fire door body 1 have excellent fire resistance, durability and strength. The first fireproof layer 12 is made of perlite board, which has a fireproof effect. The second fireproof layer 13 is asbestos filler, which has a high fire resistance. By setting the outer layer 11, the first fireproof layer 12 and the second fireproof layer 13, the fireproof performance of the fire door body 1 can be further improved, thereby improving the fireproof effect of the fire door body 1.
[0024] A water tank 2 is arranged on any side of the fire door body 1, and a water pump 21 is arranged inside the water tank 2. The output end of the water pump 21 is connected to a connecting pipe 22. The water outlet end of the connecting pipe 22 passes through the water tank 2 and is connected to one end of a water spray pipe 3. A plurality of nozzles 31 are evenly distributed on the water spray pipe 3, and the nozzles 31 are respectively arranged on the left and right side surfaces of the water spray pipe 3.
[0025] Specifically, water stored in the water tank 2 is extracted by the water pump 21 (it should be noted that the utility model uses water to extinguish fire, but according to the location and actual requirements, the water in the water tank 2 can be replaced by foam fire extinguishing agent, and the water pump 21 can be replaced by a foam pump group dedicated to foam fire extinguishing agent), and is transported to the water spray pipe 3 through the connecting pipe 22, and the water spray pipe 3 sprays the transported water outward through the nozzle 31. The nozzle 31 is symmetrically arranged on the left and right side surfaces of the water spray pipe 3, that is, the nozzle 31 is respectively located on the front and back sides of the fire door body 1, so that the nozzle 31 can extinguish the fire on the front and back sides of the fire door body 1 at the same time, thereby improving the fire extinguishing effect, and thereby effectively improving the practicality of the fire door body 1. It should be noted that the water tank 2 is made of the same steel as the outer layer 11, so that the water tank 2 has fire resistance, and a feed port is provided on the water tank 2 to facilitate the staff to add water to the water tank 2.
[0026] The smoke alarm 4 is located at a corner above the fire door body 1. The smoke alarm 4 is connected to the monitoring terminal through wireless transmission technology. The monitoring terminal is provided with a control module. The output end of the control module is respectively connected to the signal between the alarm device and the water pump 21. The monitoring terminal has data conversion and information analysis functions. The output end of the smoke alarm 4 is connected to the input end of the data conversion and information analysis, and the output end of the data conversion and information analysis is connected to the input end of the control module.
[0027] Specifically, the smoke alarm 4 monitors the change of smoke concentration (it should be noted that the utility model adopts the smoke alarm 4, but a temperature sensor can also be selected according to the location and actual requirements). The smoke alarm 4 transmits the monitored data to the monitoring terminal through wireless transmission technology. The data monitored by the smoke alarm 4 is an analog signal. The monitoring terminal converts the data into a digital signal through data conversion, and then performs information analysis on the digital signal. If the preset smoke concentration threshold is reached (the smoke concentration reaches 5%OBS / M-15%OBS / M, which is abnormal), the control module will control the alarm device and the water pump 21 to start respectively, and send out a fire alarm prompt through the on-site alarm device. By starting the water pump 21, water is pumped to the sprinkler pipe 3 and sprayed out to extinguish the fire. Through the above process, the active fire protection function of the fire door body 1 can be realized, which not only increases the practicality of the fire door body 1, but also can suppress or extinguish the flames burning around the fire door body 1 to a certain extent, thereby effectively preventing the spread of fire.
[0028] Working principle: The fire door body 1 improves the fire resistance of its own door body through the outer layer 11, the first fireproof layer 12 and the second fireproof layer 13. When the smoke alarm 4 detects the occurrence of a fire, the monitoring terminal can control the water pump 21 through the control module to extract water from the water tank 2 and transport it to the water spray pipe 3, and then the water spray pipe 3 sprays the water outward through the nozzle 31 to extinguish the fire, so that the fire door body 1 has the function of active fire extinguishing, and the nozzle 31 is respectively located on the front and back sides of the fire door body 1. The water sprayed by the nozzle 31 can extinguish the fire on the front and back sides of the fire door body 1 at the same time, and can suppress or extinguish the flames burning around the fire door body 1 to a certain extent, thereby effectively preventing the spread of fire.
