Description

Technical Field

[0001] The invention belongs to the technical field of fire fighting, and in particular relates to fire emergency escape detection equipment for large public buildings. Background Art

[0002] At present, compared with ordinary buildings, large public buildings have more complex structures, denser populations, and more concentrated wealth. Fires have a higher outbreak rate in emergencies in large public buildings. The incidence of fires has been rising in recent years both at home and abroad. The economic losses and casualties caused by fires have attracted widespread attention from the society. In the prior art, large public buildings have large spaces. When a fire occurs, the air naturally diffuses, causing the smoke generated by the fire to drift to the sensor for sensing. However, the slow diffusion of smoke results in poor detection timeliness. At the same time, the concentration of smoke gradually decreases during the diffusion of smoke, making it impossible to quickly identify the fire source in places where sensors are not installed. Fixed sensors are unable to determine the overall smoke concentration in the room, which results in error reporting in smoking areas of public buildings.

[0003] Therefore, those skilled in the art provide a large public building fire emergency escape detection device to solve the problems raised in the above background technology. Summary of the invention

DETAILED DESCRIPTION

[0042] See also Figure 1 In an embodiment of the present invention, a large public building fire emergency escape detection device comprises:

[0043] The upper guide frame 1 is suspended horizontally on the top plate of the building;

[0044] A driving seat 12 is slidably disposed on the upper guide frame 1, and a mounting member 11 is fixed below the driving seat 12;

[0045] An environmental smoke detection component 2 is fixed to the driving seat 12 via the mounting member 11, and the environmental smoke detection component 2 can perform all-round and regular detection of indoor air in public buildings; and

[0046] The fire extinguishing component 3 is relatively rotatably arranged below the environmental smoke detection component 2. The fire extinguishing component 3 can timely extinguish the fire source points in the indoor space of the public building detected by the environmental smoke detection component 2.

[0047] In this embodiment, the environmental smoke detection component 2 includes:

[0048] Outer housing 21;

[0049] An inner air chamber 22, the circumference of which is opened on the outer casing 1;

[0050] The main exhaust fan blades 23 are relatively rotatably arranged in one of the inner air chambers 22, and are used to introduce the indoor air flow into the inner air chamber 22;

[0051] Auxiliary blades 24 are correspondingly rotatably arranged in the other inner air chambers 22, and the auxiliary blades 24 can introduce indoor airflow into the inner air chambers 22 under the action of rotation;

[0052] The fixed ring bin 25 is arranged in the middle of the outer casing 21, the inner air bin 22 corresponding to the main exhaust fan blade 23 is connected to the fixed ring bin 25, and the other inner air bins 22 are connected to the fixed ring bin 25 through the transfer tube 27; wherein the other end of the fixed ring bin is connected to an external smoke detection device (not shown in the figure), so that the indoor airflow introduced into the fixed ring bin is subjected to smoke detection, so as to realize the fire smoke detection of public buildings;

[0053] A partitioning page 26 is rotatably disposed in the fixed ring chamber 25 in a circumferential sealing manner and divides the fixed ring chamber 25 into a plurality of air storage chambers;

[0054] A flow blocker 28 is coaxially arranged on the partition page 26 so as to be relatively slidable. The partition page 26 is provided with a plurality of through holes. The flow blocker 28 can seal and block each through hole under the action of sliding; and

[0055] The inner guide leaf is rotatably arranged in the dividing page plate 26. In particular, during use, the main exhaust fan blades and the auxiliary fan blades can work together to discharge the airflow at a fixed point in the room to one of the air storage chambers (at this time, the baffle block internally blocks the dividing page plate). After the driving seat drives the environmental smoke detection component to move a certain distance, the main exhaust fan blades and the auxiliary fan blades introduce the airflow again, and the other air storage chamber can perform corresponding storage. After repeated operation, multi-point air flow sampling of the overall orientation of the building interior can be achieved. Then, the baffle slides to make the through hole in an open and closed state. At this time, the inner guide leaf simultaneously delivers the airflow in each air storage chamber to the external smoke detection device, thereby realizing the determination of the smoke concentration in the overall indoor air flow to avoid error reporting.

[0056] As a preferred embodiment, it also includes:

[0057] The airflow tube 4 is vertically connected to each of the internal air bins 22 corresponding to the auxiliary fan blades 24. One end of the airflow tube 4 is connected to an airflow pump (not shown in the figure). Each of the auxiliary fan blades 24 can introduce airflow into the interior of a public building under reverse rotation. In particular, in the sealed space of a public building, in order to further improve the smoke detection effect, at this time, by discharging inert gas into the sealed space of the public building, an airflow squeezing and exhausting effect is formed in the detection area, thereby reducing smoke diffusion at the fire site, so that the main exhaust fan blades can completely introduce the smoke at the corresponding detection point into the fixed ring bin, thereby improving the detection accuracy and quickly identifying fire accidents.

[0058] In this embodiment, the fire extinguishing assembly 3 includes:

[0059] Connecting column 31;

[0060] A rotating disk 32 is rotatably sleeved on the connecting column 31. A driving motor is installed on the connecting column 31. The output end of the driving motor is connected to the rotating disk 32 for transmission through gear meshing.

[0061] A side bracket 33, circumferentially arranged on the rotating disk 32;

[0062] A drainage pipe 34 is provided corresponding to each of the side brackets 33, and a plurality of spray heads are provided on the drainage pipe 34;

[0063] A transmission rod 35 is transversely fixed on each of the side brackets 33, and a mounting guide frame 36 is slidably provided on the transmission rod 35;

[0064] A guide wheel, rotatably disposed on the mounting guide frame 36 and in contact with the drain pipe 34;

[0065] A hydraulic telescopic rod 37 is vertically fixed below the rotating disk 32, and a connecting plate is transversely fixed to the output end of the hydraulic telescopic rod 37; and

[0066] The fixed support rod 38 is rotatably connected to the connecting plate, and the other end of the fixed support rod 38 is respectively hinged on each of the mounting guide frames 36, wherein each spray head on the drain pipe can perform fixed-point firefighting work with the rotation of the rotating disk to achieve rapid fire extinguishing.

[0067] In this embodiment, the drainage pipe 34 is made of PVC material, and the bending curvature is adjusted by the mounting guide frame 36 during lateral displacement.

[0068] In this embodiment, the mounting guides 36 on the opposite sides are respectively located at different positions of the drive rods 35. In particular, the vertical extension and contraction of the hydraulic telescopic rod changes the curvature of the drain pipe so that the fire extinguishing points of the nozzles arranged thereon can be targeted at the fire source, thereby improving the fire extinguishing effect. In particular, the drain pipes on the opposite sides can be in different bending states, so that the fire extinguishing ranges of their nozzles are different. Under the action of rotation, the unburned space outside the fire source can be effectively pre-supplied with water for cooling, thereby preventing the spread of fire.

[0069] As a preferred embodiment, it also includes:

[0070] The air flow nozzle 39 is vertically fixed on one side of each of the mounting guide frames 36. The air flow nozzle 39 can assist in forming a flame retardant zone at the fire source point under the rotation of the rotating disk 32. In particular, the inert gas or water vapor mist sprayed from the air flow nozzle can effectively reduce the flow of air into the combustion zone outside the fire source and avoid the combustion of oxygen, thereby realizing the combined use of asphyxiation extinguishing and cooling extinguishing to further improve the fire fighting effect.

[0071] In this embodiment, a main fire extinguishing nozzle 5 is vertically arranged directly below the rotating disk 32. The main fire extinguishing nozzle 5 is connected to an external water supply pump through a telescopic tube. A fine-tuning telescopic rod 51 is also arranged on one side of the main fire extinguishing nozzle 5. One end of the fine-tuning telescopic rod 51 is connected to the connecting plate.

[0072] Specifically, during use, for public building areas with different spatial ranges, the environmental smoke detection component can, on the one hand, locally introduce and detect air flow at various points in the room under the action of displacement, thereby realizing the determination of smoke concentration in the overall indoor air flow and avoiding false alarms; on the other hand, in a small space, by discharging inert gas into the sealed space of the public building, an air flow squeezing and exhaust effect is formed in the detection area, reducing smoke diffusion at the fire site, so that the main exhaust fan blades can completely introduce the smoke at the corresponding detection point into the fixed ring warehouse, thereby improving detection accuracy and avoiding detection errors caused by too low smoke concentration; in particular, the fire extinguishing component can combine suffocation extinguishing and cooling extinguishing for the fire source to avoid the spread of fire.

[0073] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
