Description

Technical Field

[0001] This application belongs to the field of fire protection equipment technology, and in particular relates to an automated fire protection device for public areas. Background Technology

[0002] In public areas such as large shopping malls, exhibition halls, and stadiums, where people are densely populated and spaces are open, fire prevention and control are of paramount importance. Automated fire protection devices are one of the equipment that ensures fire safety in such areas.

[0003] In existing technologies, fire sprinklers, as widely used automated fire suppression devices in public areas, can automatically activate and spray water to extinguish fires upon detection, providing a fundamental guarantee for early fire control in public areas. However, existing fire sprinklers have significant limitations in practical applications; their spray range is relatively narrow and cannot meet the fire protection needs of large public areas requiring a wide coverage area. To achieve fire protection coverage over most areas of large public areas and ensure timely fire suppression in the event of a fire, it is necessary to install a large number of fire sprinklers.

[0004] Installing too many fire sprinklers not only significantly increases the overall construction cost of the fire protection system, including equipment procurement and installation costs, but may also interfere with the overall decoration style and aesthetics of public areas. Furthermore, in some large public areas with complex structures, even with a large number of fire sprinklers installed, gaps can still easily form between them due to the limited spray range of each sprinkler, creating blind spots that require improvement. Utility Model Content

[0005] The purpose of this application is to provide an automated fire protection device for public areas that can solve the above-mentioned problems.

[0006] The purpose of this application is to provide an automated fire protection device for public areas, comprising: The main body has a fluid channel at its top for fluid to enter, with an inlet and an outlet at each end of the fluid channel; A stopper, set on the main body and used to block the outlet, has a through groove in the center; A glass tube, one end of which is placed in a through groove, and a heat-sensitive liquid is stored inside it; A water spray plate is located at the bottom of the main body, including a central part and a diffuser part located at the edge of the central part. The diffuser part can diffuse the fluid outward. The other end of the glass tube is installed on the main body and located above the sprinkler plate.

[0007] The aforementioned automated fire-fighting device for public areas uses a main body as its load-bearing component. A fluid channel at its top connects to water pipes, providing a pathway for the fluid needed for fire suppression and ensuring smooth fluid flow to subsequent components. A stopper installed on the main body blocks the outlet, preventing fluid flow in non-fire conditions. A groove in the center of the stopper provides precise positioning for the glass tube, ensuring stable fixation and temperature sensing. The thermosensitive liquid stored inside the glass tube senses fire temperatures based on the ambient temperature requirements of different public areas, using different colors corresponding to different expansion thresholds. When the ambient temperature reaches the thermosensitive liquid's expansion threshold, the glass tube ruptures, the stopper loses support, the outlet opens, and the fluid flows out and enters the subsequent sprinkler system, thus responding promptly to fires. This solves the problem of inaccurate temperature sensing or delayed triggering that can occur with fire sprinklers. A sprinkler disc installed at the bottom of the main body, with its center serving as the initial fluid receiving component, evenly guides the fluid flowing from the outlet to the diffuser. The diffuser effectively expands the spray range, reducing the number of fire sprinklers required.

[0008] The different colors of the thermosensitive liquids correspond to different critical expansion temperatures: orange has a trigger temperature of 57℃, red has 68℃, yellow has 79℃, green has 93℃, and blue has 141℃.

[0009] Furthermore, the diffusion section includes: The first diffuser plate is fan-shaped and positioned on both sides of the center. The second diffuser is fan-shaped and located on the side of the headquarters, and the angle between the center line of the second diffuser and the center line of the first diffuser is 90°. There are two of each of the first and second diffuser sheets.

[0010] Both the first and second diffuser plates in the diffuser section are arranged in a fan shape. The first diffuser plate is installed on both sides of the central part, and the second diffuser plate is installed on the side of the central part, with their center lines distributed at a specific angle. Two of each type are installed, enabling the fluid to be guided and diffused from multiple directions. Through the multi-angle distribution of multiple sets of fan-shaped diffuser plates, the fluid can diffuse in multiple directions around the device, effectively expanding the fluid spray coverage area. This eliminates the need for a large number of installations to cover large public areas, reducing the number of installations required and lowering costs. It also avoids the interference of too many nozzles on the decoration style and aesthetics of the public area.

[0011] In addition, the multi-angle diffusion design can reduce the coverage gap between nozzles, reduce the probability of fire blind spots, and ensure that the fluid can more comprehensively cover the possible fire area when a fire occurs, thus improving the comprehensiveness of fire suppression.

[0012] Furthermore: a slot is provided between adjacent first and second diffuser sheets, with the slot extending to the center.

[0013] The slots between adjacent first and second diffuser plates, extending to the center, provide a downward flow channel for some fluid without affecting the spraying effect around the diffuser. This solves the problem of existing fire sprinklers focusing on peripheral coverage while neglecting the area directly below. While the fluid diffuses outward through the diffuser plates to cover the surrounding area, some fluid can flow directly downward through the slots, effectively covering the area directly below the device and eliminating potential fire blind spots. This ensures timely fluid spraying regardless of whether the fire occurs around or directly below the device, preventing rapid fire spread due to uncovered areas below and further improving fire suppression reliability.

[0014] Furthermore, the first diffuser and the second diffuser form an elliptical structure, and the distance from the first diffuser to the center of the circle is greater than the distance from the second diffuser to the center of the circle.

[0015] The elliptical structure formed by the first and second diffuser plates, combined with the design that the distance from the first diffuser plate to the center is greater than that from the second diffuser plate, results in an elliptical distribution of the coverage area after fluid diffusion. Compared to the common circular coverage area of ​​existing fire sprinklers, the elliptical coverage is better suited to the long, irregular shapes of spaces in large public areas. It extends the coverage area further along the longer direction corresponding to the first diffuser plate, avoiding gaps caused by mismatches between the coverage shape and the space. This structure allows for more flexible coverage of large public areas based on their spatial characteristics, reducing the need for additional sprinkler installations to accommodate different spatial shapes. While reducing costs, it further expands the effective coverage area of ​​a single unit, ensuring more comprehensive fire coverage in large public areas with different structures, reducing blind spots, and improving overall fire protection effectiveness.

[0016] Furthermore, both the first diffuser sheet and the second diffuser sheet are inclined downwards.

[0017] The downward-sloping design of both the first and second diffuser plates guides the fluid to settle downwards as it diffuses outwards, preventing improper coverage height caused by an overly horizontal diffusion direction. This tilted design allows for more even distribution of fluid across different heights and horizontal positions within the coverage area, reducing splash loss during diffusion and improving fluid utilization and extinguishing efficiency. Furthermore, the tilted design prevents fluid from concentrating at a particular height or in a localized area, ensuring a stable water flow to all locations within the coverage area.

[0018] Furthermore, both the first and second diffuser sheets have curved edges on their sides.

[0019] The arc-shaped design of the side edges of the first and second diffuser plates reduces the frictional resistance between the fluid and the edge of the diffuser plate during the diffusion process, guides the fluid to flow smoothly along the edge, makes the fluid distribution more uniform during the diffusion process, and makes the water spray volume at each position in the coverage area more stable, avoiding the situation of excessive or insufficient water in some places, and improving the reliability of fire extinguishing.

[0020] The beneficial effects of this application are: 1. Through the multi-angle distribution of multiple sets of fan-shaped diffusers, the fluid can diffuse in multiple directions around the device, effectively expanding the spray coverage of the fluid, without relying on a large number of installations to cover large public areas. 2. The multi-angle diffusion design can also reduce the coverage gap between nozzles, reduce the probability of fire blind spots, and ensure that the fluid can more comprehensively cover the possible fire area when a fire occurs, thus improving the comprehensiveness of fire fighting. 3. The design of both the first and second diffuser plates tilting downwards can guide the fluid to settle downwards while diffusing outwards, avoiding improper coverage height caused by the fluid diffusing in an overly horizontal direction.

Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0025] The automated fire protection device for public areas provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0026] Example 1: like Figures 1 to 4 As shown in the figure, this application provides an automated fire protection device for public areas, including: The main body 100 has a fluid channel 110 at its top for fluid to enter, and the two ends of the fluid channel 110 are respectively provided with an inlet and an outlet; A plug 200 is disposed on the main body 100 and used to block the outlet. A through groove 210 is provided in the center of the plug 200. A glass tube 300, one end of which is located in a through groove 210, contains a thermosensitive liquid; A water spray plate 400 is disposed at the bottom of the main body 100, including a central part 410 and a diffuser part 420 located at the edge of the central part 410. The diffuser part 420 is capable of diffusing fluid outward. The other end of the glass tube 300 is installed on the main body 100 and located above the sprinkler plate 400.

[0027] In some embodiments of this application, such as Figure 1As shown, the above-mentioned automated fire-fighting device for public areas uses a main body 100 as the supporting component. A fluid channel 110 on its top connects to a water pipe, providing a path for the fluid needed for fire suppression and ensuring smooth fluid flow to subsequent components. A stopper 200 is installed on the main body 100 and blocks the outlet, preventing fluid flow in non-fire conditions. The through-groove 210 in the center of the stopper 200 provides precise installation positioning for the glass tube 300, ensuring stable fixation and enabling it to function as a temperature sensor. The thermosensitive liquid stored inside the glass tube 300 can sense the temperature of a fire by using different colors corresponding to different expansion thresholds, based on the ambient temperature requirements of different public areas. When the ambient temperature reaches the expansion threshold of the thermosensitive liquid, the glass tube 300 ruptures, the stopper 200 loses support, opening the outlet and allowing the fluid to flow out and enter the subsequent sprinkler system, thus responding promptly to a fire. This solves the problem of inaccurate temperature sensing or delayed triggering that may exist with fire sprinklers. The sprinkler plate 400 is installed at the bottom of the main body 100. Its central part 410 serves as the initial fluid receiving component, which can evenly guide the fluid flowing out of the outlet to the diffuser part 420. The diffuser part 420 can effectively expand the water spraying range, thereby reducing the number of fire hose reels installed.

[0028] The different colors of the thermosensitive liquids correspond to different critical expansion temperatures: orange has a trigger temperature of 57℃, red has 68℃, yellow has 79℃, green has 93℃, and blue has 141℃.

[0029] Example 2: This application provides an automated fire protection device for public areas. In addition to the above-mentioned technical features, the automated fire protection device for public areas in this application also includes the following technical features.

[0030] like Figures 1 to 4 As shown, the diffuser 420 includes: The first diffuser plate 421 is fan-shaped and is disposed on both sides of the central portion 410; The second diffuser plate 422 is fan-shaped and disposed on the side of the headquarters, and the angle between the center line of the second diffuser 420 and the center line of the first diffuser plate 421 is 90°. There are two of each of the first diffuser plate 421 and the second diffuser plate 422.

[0031] In this embodiment, the first diffuser plate 421 and the second diffuser plate 422 of the diffuser section 420 are both arranged in a fan shape. The first diffuser plate 421 is installed on both sides of the central part 410, and the second diffuser plate 422 is installed on the side of the central part 410. The center lines of the two are distributed at a specific angle, and two of each are arranged, which can guide and diffuse the fluid from multiple directions. Through the multi-angle distribution of multiple sets of fan-shaped diffuser plates, the fluid can diffuse in multiple directions around the device, effectively expanding the spray coverage of the fluid. It eliminates the need to rely on a large number of installations to cover large public areas, reduces the number of installations, lowers costs, and avoids the interference of too many nozzles on the decoration style and spatial aesthetics of public areas.

[0032] In addition, the multi-angle diffusion design can reduce the coverage gap between nozzles, reduce the probability of fire blind spots, and ensure that the fluid can more comprehensively cover the possible fire area when a fire occurs, thus improving the comprehensiveness of fire suppression.

[0033] Example 3: This application provides an automated fire protection device for public areas. In addition to the above-mentioned technical features, the automated fire protection device for public areas in this application also includes the following technical features.

[0034] like Figures 1 to 4 As shown, a slot 430 is provided between adjacent first diffuser 421 and second diffuser 422, with the slot 430 extending to the center portion 410.

[0035] In this embodiment, a slot 430 is formed between adjacent first diffuser plates 421 and second diffuser plates 422, extending to the center portion 410. This slot 430 provides a downward flow channel for some fluid without affecting the water spraying effect around the diffuser portion 420. This solves the problem that existing fire sprinklers often focus on peripheral coverage while neglecting the area directly below. While the fluid diffuses outward through the diffuser plates to cover the surrounding area, some fluid can flow directly downward through the slot 430, effectively covering the area directly below the device and eliminating potential fire blind spots. This ensures that regardless of whether the fire occurs around or directly below the device, fluid can be sprayed promptly, preventing rapid fire spread due to uncovered areas below, and further improving fire suppression reliability.

[0036] Example 4: This application provides an automated fire protection device for public areas. In addition to the above-mentioned technical features, the automated fire protection device for public areas in this application also includes the following technical features.

[0037] like Figures 1 to 4As shown, the first diffuser plate 421 and the second diffuser plate 422 form an elliptical structure, and the distance from the first diffuser plate 421 to the center of the center portion 410 is greater than the distance from the second diffuser plate 422 to the center of the center portion 410.

[0038] In this embodiment, the elliptical structure formed by the first diffuser plate 421 and the second diffuser plate 422, combined with the design that the distance from the first diffuser plate 421 to the center of the center portion 410 is greater than that of the second diffuser plate 422, results in an elliptical distribution of the coverage area after fluid diffusion. Compared to the common circular coverage range of existing fire sprinklers, the elliptical coverage is more adaptable to the long and irregular spatial layouts of large public areas. It can further extend the coverage range in the longer direction corresponding to the first diffuser plate 421, avoiding coverage gaps caused by the mismatch between the coverage shape and the space. This structure can more flexibly achieve coverage of a wide area according to the spatial characteristics of large public areas, reducing the need to increase the number of sprinkler installations to adapt to different spatial shapes. While reducing costs, it further expands the effective coverage area of ​​a single device, ensuring more comprehensive fire coverage in large public areas with different structures, reducing fire blind spots, and improving the overall fire protection effect.

[0039] Furthermore, both the first diffuser plate 421 and the second diffuser plate 422 are inclined downwards.

[0040] The downward-sloping arrangement of both the first diffuser plate 421 and the second diffuser plate 422 guides the fluid to settle downwards as it diffuses outwards, preventing improper coverage height caused by an overly horizontal diffusion direction. This tilted design allows for more even distribution of fluid across different heights and horizontal positions within the coverage area, reducing splash loss during diffusion and improving fluid utilization and extinguishing efficiency. Furthermore, the tilted design prevents fluid from concentrating excessively at a certain height or in a localized area, ensuring a stable water flow to all locations within the coverage area.

[0041] Furthermore, the side edges of both the first diffuser plate 421 and the second diffuser plate 422 are curved edges.

[0042] The arc-shaped design of the side edges of the first diffuser plate 421 and the second diffuser plate 422 can reduce the frictional resistance between the fluid and the edge of the diffuser plate during the diffusion process, guide the fluid to flow smoothly along the edge, make the fluid distribution more uniform during the diffusion process, make the water spray volume at each position in the coverage area more stable, avoid the situation of excessive or insufficient water in some places, and improve the reliability of fire extinguishing.
