However, the upper pipe in this utility model is suspended from the top of the carport and exposed to the air, making it susceptible to corrosion. In extreme cases, it may deform due to external impact, affecting the normal functioning of the fire extinguishing function; the suspension method of the upper pipe also has the problems of wasted space and poor aesthetics.

[0004] Therefore, how to design a fire sprinkler system that is compatible with the structure of the carport has become a technical problem that urgently needs to be solved in this field. Utility Model Content

[0005] To address the shortcomings of the existing technology, this utility model provides a fire sprinkler device with an embedded, integrated design that can provide shielding protection for vehicles while meeting the needs of efficient fire extinguishing.

[0006] This utility model provides a fire sprinkler system, including a carport and sprinkler components;

[0034] To better understand the above technical solutions, a detailed description of the solutions will be provided below in conjunction with the accompanying drawings and specific embodiments. Obviously, the described embodiments are merely some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0035] The terminology used in the embodiments of this utility model is for the purpose of describing particular embodiments only and is not intended to limit the utility model. The singular forms “a,” “the,” and “the” used in the embodiments of this utility model and the appended claims are also intended to include the plural forms, and “multiple” generally includes at least two unless the context clearly indicates otherwise.

[0036] It should also be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that an article or device that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such an article or device. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the article or device that includes said element.

[0037] This utility model provides a fire sprinkler system, including a carport and sprinkler components;

[0038] like Figure 1 As shown, the carport includes a main frame 11, supporting horizontal tubes 12 and a canopy. The canopy is located on the top of the main frame 11, and at least one supporting horizontal tube 12 is fixed to the main frame and abuts against the bottom of the canopy.

[0039] like Figures 2-5 As shown ( Figure 4 The solid line represents the sprinkler riser, the dashed line represents the sprinkler branch pipe, and the arrow represents the fire sprinkler head. The sprinkler assembly includes a sprinkler riser 21 connected to the fire hydrant network and at least one sprinkler branch pipe 22 connected to the sprinkler riser.

[0040] The sprinkler riser is fixed to the main frame 11, and the sprinkler branch pipe 22 is located inside the supporting horizontal pipe 12. Each supporting horizontal pipe 12 is provided with at most one sprinkler branch pipe 22, and the sprinkler branch pipe 22 is provided with at least one fire sprinkler head 23 passing through the supporting horizontal pipe 12.

[0041] The main frame, supporting cross tubes, and canopy of the carport work together to form a stable spatial structure, providing shelter from wind and rain, as well as sun protection and heat insulation for vehicles. The sprinkler system is connected to the fire hydrant network, which can quickly spray water to extinguish fires in the event of a fire, effectively controlling the spread of fire, reducing fire losses, and protecting the safety of vehicles and personnel.

[0042] Specifically, the main frame supports the entire weight of the carport, with supporting horizontal pipes fixed to the main frame and abutting against the bottom of the canopy. These horizontal pipes also accommodate the sprinkler branch pipes, balancing the carport's structural integrity with fire safety functions. Placing the sprinkler branch pipes within the supporting horizontal pipes makes the overall structure compact and improves space utilization. The supporting horizontal pipes also protect the sprinkler branch pipes from wind, sand, rain, and snow erosion, extending their service life and ensuring the reliability and stability of the entire sprinkler structure. Figure 3 As shown, the canopy of this fire sprinkler system has an arc-shaped cross-section along the vertical sprinkler branch pipe 22, and the direction of the fire sprinkler head 23 is perpendicular to the tangent of the arc. This arrangement of the fire sprinkler head can minimize the impact of the sprayed water with the lower surface of the canopy, reduce water splashing and loss, and improve the fire extinguishing effect. The deflector plate 24 in this fire sprinkler system is disc-shaped, which can disperse the water flow into fine water droplets and form a uniform water mist when the sprinkler head is activated.

[0043] like Figure 3 As shown, a buffer insulation layer 25 can also be filled between the spray branch pipe and the support horizontal pipe to reduce the possibility of collision between the spray branch pipe and the support horizontal pipe, while improving the support strength of the support horizontal pipe.

[0044] Optionally, the main frame of the carport canopy can be made of H-beams, with a recessed section in the middle to accommodate the sprinkler risers, improving the overall space utilization and aesthetics of the carport. Alternatively, the supporting horizontal pipes can be directly used as sprinkler branch pipes, increasing pipe reusability, saving materials, and simplifying construction. Both the sprinkler risers and branch pipes are fitted with insulation and buffer insulation layers, respectively. Both layers protect the pipes and slow down corrosion of the pipe surface; the insulation layer effectively prevents water flowing through the sprinkler risers from freezing in cold weather, ensuring the normal operation of the sprinkler structure; the buffer insulation layer provides cushioning when the sprinkler branch pipes vibrate during spraying and also has heat insulation properties, reducing the impact of increased ambient temperature caused by fire on the water temperature in the sprinkler risers, thus improving the fire extinguishing and cooling effect.

[0045] In practice, the insulation layer and the buffer insulation layer can be integrally molded from the same material, such as plastic sponge, polyurethane foam, phenolic foam, etc., without specific limitations. Alternatively, they can be molded from different materials, such as rock wool, aluminum silicate, polystyrene foam, etc. for the insulation layer, and polyethylene closed-cell foam board, rubber and plastic sponge, foamed polypropylene, etc. for the buffer insulation layer, without specific limitations.

[0046] In other embodiments, a plurality of supporting horizontal pipes 12 are fixedly provided on the main frame 11. All supporting horizontal pipes 12 are arranged in parallel, and at least two supporting horizontal pipes 12 form a spray group. The spray group includes at least the two supporting horizontal pipes with the largest distance between them. The two supporting horizontal pipes with the largest distance between them are respectively provided with a first spray branch pipe and a second spray branch pipe. In this case, the spray branch pipe of the spray assembly includes the first spray branch pipe and the second spray branch pipe, such as... Figure 6 The diagram shows the configuration of two supporting horizontal pipes 12 (solid lines represent sprinkler risers, dashed lines represent sprinkler branch pipes, and arrows represent fire sprinkler heads). Positioning the sprinkler branch pipes within the two furthest supporting horizontal pipes ensures that the sprinkler coverage extends to the entire carport area, reducing blind spots. In the event of a large fire, simultaneous spraying from both sprinkler branch pipes shortens extinguishing time and improves firefighting efficiency. Furthermore, the spraying from the branch pipes on both sides also helps to limit the fire's spread, preventing it from reaching other areas outside the carport.

[0047] like Figure 1 and 6 As shown, in the carport component of this fire sprinkler system, the edge support pipe 13 is fixedly connected to the main frame 11. Considering the sprinkler range and sprinkler effect, no sprinkler branch pipe is installed inside it, and it only plays a supporting role for the entire carport structure.

[0048] like Figure 7 As shown, when installing fire sprinkler heads 23, the fire sprinkler heads 23 on adjacent sprinkler branch pipes 22 can be installed opposite each other. When fire sprinkler heads are installed opposite each other, since they are processed using the same structure, there is no need to frequently adjust the processing technology and equipment, which can improve processing efficiency. During installation, it can also reduce construction errors and reduce the impact on the sprinkler effect.

[0049] Preferred, such as Figure 8 As shown, when installing fire sprinkler heads 23, the fire sprinkler heads 23 on adjacent sprinkler branch pipes 12 are staggered. The staggered arrangement of fire sprinkler heads can more evenly cover the area under the carport, eliminating blind spots in water spraying. In the event of a fire, the staggered distribution of fire sprinkler heads can form a denser water mist network, improving fire extinguishing efficiency; it can also avoid fire extinguishing blank areas caused by the failure of a single fire sprinkler head, improving the fault tolerance of this fire sprinkler system.

[0050] Preferably, the height of the first sprinkler branch pipe above the ground is h1, and the spacing between adjacent fire sprinkler heads is d1; the height of the second sprinkler branch pipe above the ground is h2, and the spacing between adjacent fire sprinkler heads is d2, where h1 ≥ h2 and d1 ≥ d2. The larger spacing between the fire sprinkler heads on the first sprinkler branch pipe ensures a wider spray area; the second sprinkler branch pipe, with its denser arrangement of fire sprinkler heads, can create a dense water mist. In the event of a fire, the two sprinkler branches work together to optimize the spraying effect.

[0051] Optionally, when sprinkler branch pipes are installed in the two farthest supporting horizontal pipes, pressure regulating valves are installed on the sprinkler branch pipes. A pressure regulating valve can be installed on the first sprinkler branch pipe, with the height of the first sprinkler branch pipe from the ground less than that of the second sprinkler branch pipe. Alternatively, pressure regulating valves with different pressure settings can be installed on the first and second sprinkler branch pipes, with the pressure setting value and height of the first sprinkler branch pipe both being less than those of the second sprinkler branch pipe. The pressure regulating valves stabilize the pressure in the sprinkler branch pipes, preventing abnormal situations such as misfires or pipe ruptures caused by excessive water pressure fluctuations. The setting method and pressure setting value of the pressure regulating valves can be flexibly adjusted according to factors such as weather conditions, the location of the carport, and the specific fire intensity during a fire, controlling the water output speed, water jet range, and water mist area during spraying, improving the spraying effect, and making rational use of water resources.

[0052] The fire sprinkler system features a buffer pad between the supporting horizontal pipes and the canopy. This reduces direct collisions and friction between the horizontal pipes and the canopy, minimizing mechanical wear caused by vibrations from the spray impact, extending the service life of both the horizontal pipes and the canopy, ensuring the structural stability of the carport, and indirectly protecting the sprinkler branch pipes and fire sprinkler heads. The buffer pad can be made of materials with good elasticity, durability, and weather resistance, such as natural rubber, synthetic rubber, polyurethane foam, silicone, and foamed polypropylene. Alternatively, multi-layer composite materials can be used to enhance the buffer pad's performance. For example, a three-layer structure can be employed: the outer layer (wear-resistant layer) uses rubber or silicone to protect the internal materials from environmental corrosion; the middle layer (buffer layer) uses highly elastic polyurethane foam or foamed polypropylene to provide cushioning and shock absorption; and the inner layer (adhesive layer) uses natural rubber or a specialized adhesive with good bonding properties to ensure a tight fit between the buffer pad and the canopy, preventing displacement or detachment.

[0053] The fire sprinkler heads in this fire sprinkler system are either pendant sprinkler heads or upright sprinkler heads.

[0054] Optionally, the fire sprinkler heads in this fire sprinkler system use glass bulbs as the heat-sensitive element. When the fire sprinkler head is a pendant type, the diameter of the glass bulb is 5mm; when the fire sprinkler head is a vertical type, the diameter of the glass bulb is 6mm. Fusible alloys can also be used as the heat-sensitive element.

[0055] Optionally, a cylindrical or conical water flow channel may be provided inside the fire sprinkler head.

[0056] The working principle of this fire sprinkler system is as follows: When a fire occurs, the ambient temperature rises, and the heat-sensitive element changes (the glass bulb ruptures or the fusible alloy melts). Water flows out through the fire sprinkler head, and the splash plate disperses the water flow into fine droplets, which are then sprayed downwards in a parabolic shape to extinguish the fire.

[0057] Although preferred embodiments of the present invention have been described, those skilled in the art, upon learning the basic inventive concept, can make other changes and modifications to these embodiments. Therefore, the appended claims are intended to be interpreted as including both the preferred embodiments and all changes and modifications falling within the scope of the present invention. Clearly, those skilled in the art can make various alterations and modifications to the present invention without departing from its spirit and scope. Thus, if such modifications and modifications fall within the scope of the claims of the present invention and their equivalents, the present invention also intends to include such modifications and modifications.
