Description

Technical Field

[0001] This utility model relates to the field of fire extinguishing technology for emergency evacuation routes, specifically a foam fire extinguishing device for emergency evacuation routes in high-rise buildings. Background Technology

[0002] Emergency evacuation routes in high-rise buildings, also known as evacuation staircases, are mainly used to provide an emergency passage for residents of high-rise buildings to escape to refuge floors.

[0003] Because emergency evacuation routes should be designed to allow residents to move freely, stairwells should not be fitted with items that obstruct or block the path. However, if a fire breaks out on a floor, the dense smoke will be released first through the windows and stairwells due to the airflow within the floor. The smoke released into the stairwells, along with the high temperature, will seriously interfere with the evacuation of residents on the upper floors, hindering their effective evacuation.

[0004] In view of this, a foam fire extinguishing device for emergency evacuation routes in high-rise buildings was designed to solve the above problems. Utility Model Content

[0035] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0036] It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of this invention.

[0037] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, a foam fire extinguishing device for emergency evacuation routes in high-rise buildings.

[0038] Example 1:

[0039] Combination Figures 1-5As shown, this utility model provides a foam fire extinguishing device for emergency evacuation passages in high-rise buildings, including a foam generating mechanism 100, a fire-fighting mechanism 200 installed on the foam generating mechanism 100, and two sets of smoke exhaust mechanisms 300 installed on both sides of the foam generating mechanism 100. The foam generating mechanism 100 is used to create a foam barrier and absorb flames and smoke in the stairwell gaps, the fire-fighting mechanism 200 is used to provide a reaction carrier for the solvent, and the smoke exhaust mechanism 300 is used to actively absorb and release the smoke rising from the stairwell.

[0040] The foaming mechanism 100 includes a heat insulation pipe 110 and two sets of clamps 150, and multiple nozzles 130 are evenly distributed on the inner side of the heat insulation pipe 110, and a pressurizing nozzle 140 is installed at the outer end of the nozzle 130.

[0041] Furthermore, the clamp 150 has a U-shaped structure, and the inner wall of the clamp 150 is provided with two symmetrically distributed arc-shaped pads;

[0042] The inner wall of the heat insulation pipe 110 is provided with a water-containing cavity 120, and the top of the heat insulation pipe 110 is provided with two cylindrical ends, and the middle of the cylindrical ends is provided with an insertion hole.

[0043] The interior of the water-containing cavity 120 is filled with a cooling solution;

[0044] A liquid injection port is provided at the top of one end of the heat insulation tube 110, and the liquid injection port is connected to the inner cavity of the water-containing cavity 120.

[0045] The fire protection system 200 includes a base 210 installed on the top of the heat insulation pipe 110, an outer frame 220 installed on the base 210, a smoke sensor 230 installed inside the outer frame 220, and a central control assembly 240 installed on the smoke sensor 230.

[0046] The smoke exhaust mechanism 300 includes two connecting pipes 310 at both ends of the heat insulation pipe 110, and a smoke pipe 350 at the other end of the connecting pipe 310. A smoke inlet groove 360 ​​is provided on the inner side of the smoke pipe 350.

[0047] When a fire breaks out on a floor of a building, the flames and smoke will flow into the stairwell due to the airflow inside the building. The moment the smoke enters, the smoke sensor 230 will capture the rising smoke and then quickly transmit the data to the cloud through the central control component 240. The cloud will then control the solvent storage tanks 290 at the alternating positions of the two adjacent stairwells.

[0048] After the materials inside the solvent storage tank 290 are mixed and reacted, the foam and carbon dioxide will enter the two guide pipes 270 through the two joints 250 and the two springs 260. They will eventually converge in the inner cavity of the heat insulation pipe 110. As the pressure in the inner cavity of the heat insulation pipe 110 gradually increases, the foam and carbon dioxide will eventually be sprayed outward at high pressure from multiple pressurized nozzles 140, which will eventually set up a barrier in the gap of the stairwell. At this time, the flame can be effectively blocked. At the same time, the smoke passing between the two smoke pipes 350 will also be actively absorbed and quickly released outward along the exhaust pipe, thereby avoiding affecting the evacuation of the residents on the upper floor.

[0049] Example 2:

[0050] Combination Figure 5 As shown, based on Embodiment 1, the top of the base 210 is provided with a pre-installed groove, and two connectors 250 are provided in the pre-installed groove, and the central control assembly 240 is installed on the outer frame 220.

[0051] A horizontally placed solvent storage tank 290 is provided between the two connectors 250;

[0052] A spring 260 is installed between the base 210 and the connector 250;

[0053] The outer end of the connector 250 is connected to the guide tube 270, and the other end of the guide tube 270 is equipped with the insertion tube 280;

[0054] The 280mm cannula is inserted into the socket.

[0055] Preferably, the insertion tube 280 is bolted to the base 210, and the tube 280 is adapted to extend into the insertion hole.

[0056] The central control unit 240 has wires installed at both ends of its top.

[0057] The connector 250 has an overall T-shaped structure, and an anti-slip washer is provided in the disc-shaped port at the inner end of the connector 250.

[0058] Preferably, a semi-cylindrical groove is provided on the top of the base 210, and one end of the spring 260 is fixed on the inner wall of the base 210, while the other end of the spring 260 is fixedly installed on the outside of the connector 250.

[0059] Four clamps 150 are evenly distributed on the outside of the insulation pipe 110 and are fixedly installed on the side of the platform of the two floors by bolts.

[0060] Example 3:

[0061] Combination Figures 3-5 As shown, based on Embodiment 1, the smoke exhaust mechanism 300 also includes two end caps 320, and an inner gasket 330 is installed in the middle of the end caps 320;

[0062] An anti-overflow inner tube 340 is installed inside each of the two adjacent inner pads 330;

[0063] The overflow-proof inner tube 340 has an overall L-shaped structure;

[0064] Both the heat insulation pipe 110 and the flue pipe 350 are made of stainless steel, and the exterior of the heat insulation pipe 110 and the flue pipe 350 are coated with an anti-rust and heat insulation paint layer.

[0065] Preferably, two adjacent end caps 320 are disposed at both ends of the adapter pipe 310, with the outer end of one end cap 320 inserted into the port of the heat insulation pipe 110 and the outer end of the other end cap 320 inserted into the port of the flue pipe 350.

[0066] Two overflow-proof inner tubes 340 are fixed at both ends of the inner cavity of the heat insulation tube 110 by welding, and the inner cavities of the two overflow-proof inner tubes 340 are connected to the inner cavities of the two flue pipes 350.

[0067] As smoke rises in the stairwell, the exhaust duct system actively absorbs the smoke through the smoke inlet 360 and finally discharges it outside the building, thus ensuring that the emergency stairwell can provide a safe refuge environment for residents on the upper floors.

[0068] The working principle and usage process of this utility model are as follows: The pre-assembled foam generating mechanism 100 is installed as a whole at the staircase alternation point of the evacuation passage using multiple clamps 150. According to the changes of the staircase rotation and folding, the required multiple sets of foam generating mechanisms 100 are set at the staircase alternation points on different floors. Then, multiple sets of smoke exhaust mechanisms 300 are used to connect the two sets of foam generating mechanisms 100 on adjacent floors, and the structure of the adapter pipe 310, end cap 320 and smoke pipe 350 connected to both ends of the heat insulation pipe 110 is shown in the attached figure below.

[0069] Once a fire breaks out on a floor of the building and causes smoke to spread to other floors, as the smoke spreads into the emergency exit, the smoke sensor 230 will detect the rising smoke and transmit the signal through the central control component 240. Finally, the material stored in the solvent storage tank 290 will be transferred through the two connectors 250 to the two guide pipes 270 under chemical reaction, and finally enter the inner cavity of the heat insulation pipe 110 through the two insertion tubes 280. As the foam and carbon dioxide continue to increase, they will eventually be sprayed outward from multiple pressurized nozzles 140. The sprayed foam and carbon dioxide will then diffuse the flames and smoke rising along the stair gaps.

[0070] At this point, the flames can be effectively blocked, while preventing flammable parts around the stairs from being damaged by high temperatures;

[0071] At the same time, a cooling solution is injected into the water-containing cavity 120. When the device is used in a high-temperature environment during a sudden fire, it can prevent the high temperature from interfering with the spray foam tube. Smoke passing through the gaps in the stairwell will also be drawn into the inner cavity of the smoke pipe 350 by the smoke inlet 360 and finally released outward along the pipeline system laid throughout the building, so as to avoid the dense smoke in the stairwell from interfering with pedestrians.

[0072] Although embodiments of the present invention have been shown and described, those skilled in the art will understand 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 claims and their equivalents.
