[0035] Example 1

[0036] This embodiment provides a modular fire protection system that enables rapid on-site installation, improves assembly efficiency, shortens assembly time, has universal expandability, is suitable for fire protection deployment in various fire protection scenarios, can achieve intelligent fire protection without human intervention, and has high reliability.

[0037] Please see Figures 1 to 5 The modular fire protection system provided in this embodiment includes a modularly designed cabinet 1, pipe assembly and monitoring components. The cabinet 1 and pipe assembly are arranged in the fire scene, and the monitoring components are installed in the pipe assembly for monitoring the fire situation.

[0038] Specifically, the cabinet 1 is made of a container, which is sturdy and durable, suitable for long-distance transportation and repeated lifting operations, and is especially suitable for international projects, remote areas and temporary deployment environments. The inner surface of the cabinet 1 is equipped with a fireproof and heat-insulating layer 14, which enables the internal components of the cabinet 1 to operate normally under high temperature or cold climate conditions.

[0039] Further, please refer to Figure 1 Cabinet 1 is equipped with a power supply interface 11 and a fire extinguishing interface 12. The power supply interface 11 is used to connect to a water source, and it connects to the fire extinguishing interface 12 and a pipe assembly to introduce water into the pipe assembly. Water is then sprayed onto the fire scene through the pipe assembly to extinguish the fire. Furthermore, a fire pump is installed inside cabinet 1. The inlet of the fire pump is connected to the power supply interface 11, and the outlet is connected to the fire extinguishing interface 12. When the fire pump is started, it draws in water and introduces it into the pipe assembly through the power supply interface 11 and the fire extinguishing interface 12. Preferably, the fire pump is a centrifugal pump or a positive displacement pump.

[0040] Optionally, an anti-corrosion layer 13 is provided on the inner surface of the cabinet 1 to give the cabinet 1 good anti-corrosion and moisture and heat resistance, making it suitable for the humid environment inside the cabinet 1, extending its service life, and meeting the requirements for long-term stable operation. For example, the inner surface of the cabinet 1 is hot-dip galvanized to form the anti-corrosion layer 13, or the inner surface of the cabinet 1 is sprayed with powder coating to form the anti-corrosion layer 13. The powder coating is made of epoxy, polyester, or acrylic materials. Further, a fireproof and heat-insulating layer 14 is provided on the surface of the anti-corrosion layer 13.

[0041] In this embodiment, a control board is installed inside the cabinet 1, and the fire pump is connected to the control board. The control board can control the start and stop of the fire pump.

[0042] For example, the pipe assembly includes a main pipe 21 and several branch pipes 22, all of which are connected to the main pipe 21. The main pipe 21 is connected to the fire interface 12, and the branch pipes 22 are evenly distributed throughout the fire scene. Each branch pipe 22 is equipped with a sprinkler head 23 at intervals along its arrangement direction. The fire pump pumps water into the fire interface 12, which then leads to the main pipe 21 and further into each branch pipe 22. Water mist is released through the sprinkler heads 23 to extinguish the fire. It should be noted that the spraying range covers the entire fire scene, ensuring that fires in all areas of the fire scene can be successfully extinguished.

[0043] In other feasible embodiments, the power supply interface 11 can be connected to fire-fighting gas (such as carbon dioxide, heptafluoropropane, IG-541, etc.), and the fire pump set in this embodiment can be eliminated. Since the fire-fighting gas is stored in the high-pressure tank in a high-pressure state, the fire-fighting gas can be introduced into the main pipe 21 by opening the valve at the opening of the high-pressure tank, and further introduced into each branch pipe 22, and released through the sprinkler head 23 to extinguish the fire.

[0044] In other feasible embodiments, the power supply interface 11 can be connected to fire-fighting foam. The fire pump can be a centrifugal pump or a positive displacement pump. The fire pump is turned on to introduce the fire-fighting foam into the main pipe 21 and further into each branch pipe 22, and then released through the sprinkler head 23 to extinguish the fire.

[0045] In other feasible embodiments, the power supply interface 11 can be connected to the dry powder tank, which stores ammonium phosphate, sodium bicarbonate, etc. The fire pump set in this embodiment is eliminated. The dry powder tank is filled with high-pressure nitrogen. By opening the valve inside the dry powder tank, the high-pressure nitrogen acts on the dry powder, "pressing out" or "blowing out" the dry powder from the outlet. It is then introduced into the main pipe 21 through the fire interface 12, and further introduced into each branch pipe 22. It is then released through the sprinkler head 23 to extinguish the fire.

[0046] Furthermore, in this embodiment, the branch pipe 22 is connected to the main pipe 21 via a grooved connection, clamp connection, or threaded connection. The grooves or threads are prefabricated in the factory, allowing for quick connection between the branch pipe 22 and the main pipe 21 on-site, improving assembly efficiency and shortening assembly time. Similarly, the main pipe 21 is connected to the fire-fighting interface 12 via a grooved connection, clamp connection, or threaded connection. The grooves or threads are prefabricated in the factory, which, on the one hand, allows for quick connection between the main pipe 21 and the fire-fighting interface 12 on-site, improving assembly efficiency and shortening assembly time; on the other hand, it allows for quick disassembly and assembly of the main pipe 21 during maintenance, reducing downtime.

[0047] Optionally, based on the reserved flanges or clips of the fixed structure in the fire protection scenario, suitable special interfaces are set on the main pipe 21 and branch pipe 22 in the factory. On the one hand, they can be quickly connected with the reserved flanges or clips of the fixed structure in the fire protection scenario on site to complete the arrangement of the main pipe 21 and branch pipe 22 and improve assembly efficiency. On the other hand, they can help realize the quick disassembly and assembly of the main pipe 21 or branch pipe 22 and shorten downtime.

[0048] Preferably, both the main pipe 21 and the branch pipe 22 are made of non-alloy structural steel welded pipes. More preferably, the outer surfaces of the main pipe 21, branch pipe 22, and special interfaces are hot-dip galvanized to form an anti-corrosion layer 13, or the outer surfaces of the main pipe 21, branch pipe 22, and special interfaces are sprayed with plastic powder to form an anti-corrosion layer 13. The plastic powder is made of epoxy, polyester, or acrylic materials to give it good anti-corrosion and moisture-heat resistance, meeting the requirements for long-term stable operation.

[0049] Further, please refer to Figure 2 The branch pipe 22 has a number of pre-set openings at intervals along its arrangement direction, and a number of first pairs of interfaces 24 are installed at the openings. The first pairs of interfaces 24 are connected to their corresponding branch pipes 22 through the openings. Adaptively, a second pair of interfaces is installed at the end of the sprinkler head 23. The second pair of interfaces is connected to the first pair of interfaces 24 one by one, thereby realizing the connection between the sprinkler head 23 and the corresponding branch pipe 22.

[0050] Preferably, the first pair of interfaces 24 are integrally formed with the corresponding branch pipe 22, and the second pair of interfaces are integrally formed with the corresponding spray head 23 to improve the overall airtightness.

[0051] For example, in this embodiment, the second pair of interfaces is provided to correspond one-to-one with the first pair of interfaces 24 via grooved connection, clamp connection, or threaded connection. The grooves or threads are prefabricated in the factory. On the one hand, the first pair of interfaces 24 and the second pair of interfaces can be quickly connected on site, improving assembly efficiency and shortening assembly time. On the other hand, the spray head 23 can be quickly disassembled and assembled during maintenance, shortening downtime.

[0052] In some feasible embodiments, the branch pipe 22 includes several prefabricated segments. Adjacent segments are connected by grooved, clamp-type, or threaded connections. Prefabricating grooves or threads in the factory allows for rapid on-site assembly of the branch pipe 22, improving assembly efficiency and reducing assembly time. Furthermore, it allows for the rapid assembly of different numbers of prefabricated segments according to the dimensions required for fire-fighting scenarios, enhancing modularity and versatility. Additionally, sealing gaskets and anti-loosening nuts are provided between adjacent segments to ensure long-term operation without loosening.

[0053] In some feasible embodiments, for long-distance or high-load pipelines, the branch pipe 22 can also be prefabricated as an integral structure to reduce intermediate joints, reduce the risk of leakage, and improve pipeline rigidity and hydrodynamic performance.

[0054] Furthermore, the modular fire protection system also includes valve assemblies, which consist of several shut-off valves 31. Please refer to [further details]. Figure 1 Several shut-off valves 31 are installed one-to-one with several branch pipes 22, and several shut-off valves 31 are connected to a control board. The control board is used to control the opening and closing of the corresponding branch pipes 22. When a fire occurs in a certain area of ​​the fire scene, the control board starts the fire pump and opens the shut-off valves 31 on the branch pipes 22 in that area, introducing water into the corresponding branch pipes 22, and releasing water mist through the sprinkler heads 23 to extinguish the fire and improve the accuracy of fire fighting.

[0055] Preferably, the shut-off valve 31 is installed near the connection point between the branch pipe 22 and the main pipe 21.

[0056] Further, please refer to Figure 1 The modular fire protection system also includes adjustable brackets 4. Several adjustable brackets 4 are set in the fire scene. The main pipe 21 and the branch pipe 22 are both supported by one or more adjustable brackets 4. Since the height of the adjustable brackets 4 is adjustable, the height of the main pipe 21 and the branch pipe 22 can be adjusted on site by adjusting the height of the adjustable brackets 4, thereby adapting to the fixed structure in the fire scene.

[0057] For example, please refer to Figure 3 and Figure 4 The adjustable bracket 4 includes a base 41, two telescopic members 42, a fixed seat 43, a connecting shaft 44, a clamp 45, and a positioning screw 46. The base 41 is bolted to the bottom of the fire scene. The two telescopic members 42 are symmetrically arranged, with the bottom of the telescopic members 42 hinged to the base 41 and the top of each telescopic member 42 hinged to the fixed seat 43. The connecting shaft 44 is installed on the top of the fixed seat 43. A clamp 45 is installed at the end of the connecting shaft 44 away from the fixed seat 43. The main pipe 21 or branch pipe 22 is inserted into the clamp 45, and the clamp 45 is tightened with bolts to lock and fix the main pipe 21 or branch pipe 22. Furthermore, the telescopic component 42 includes two branch rods 421, which are hinged together by hinge shafts 47. At the same time, positioning screws 46 pass through the two hinge shafts 47 in sequence, and two locking nuts are screwed onto the positioning screws 46. The two locking nuts abut against the opposite sides of the two hinge shafts 47 respectively. By screwing the two locking nuts and adjusting the distance between the two hinge shafts 47, the height of the adjustable bracket 4 can be adjusted.

[0058] For further information, please refer to [link / reference]. Figure 1The monitoring components include a smoke sensor 51, a flame sensor 52, and a temperature sensor 53 installed on the pipe assembly. The smoke sensor 51 is used to detect smoke particles in a fire scene, the flame sensor 52 is used to detect radiation of a specific wavelength produced by the flame and emit a fire signal, and the temperature sensor 53 is used to detect the temperature in a fire scene.

[0059] Preferably, the smoke sensor 51, the flame sensor 52, and the temperature sensor 53 are pre-integrated into the main pipe 21 or the branch pipe 22 in the factory. Depending on different requirements, grooved connection, clamp connection, or threaded connection can be used.

[0060] Furthermore, please refer to Figure 5 The smoke sensor 51, flame sensor 52, and temperature sensor 53 are all connected to the control board. Smoke thresholds and temperature thresholds are pre-stored on the control board. The control board can receive the detection values ​​from the smoke sensor 51, the fire signal from the flame sensor 52, and the detection values ​​from the temperature sensor 53. When the detection value of the smoke sensor 51 exceeds the smoke threshold, the flame signal from the flame sensor 52, or the detection value of the temperature sensor 53 exceeds the temperature threshold, the fire pump is activated, introducing water into the branch pipe 22 and releasing water mist through the sprinkler heads 23 to extinguish the fire. By setting up smoke sensors 51, flame sensors 52, and temperature sensors 53, the fire scene is monitored from multiple perspectives, improving the reliability and accuracy of fire monitoring.

[0061] Please continue reading. Figure 1 This embodiment also includes a visible light camera 54 and a display 55 as part of the monitoring components. The visible light camera 54 is installed in the pipe assembly, and similarly, it is pre-integrated into the main pipe 21 or branch pipe 22 in the factory. Depending on different needs, a grooved connection, clamp connection, or threaded connection can be used. The display 55 is installed in the cabinet 1. The visible light camera 54 is used to monitor fire scenes and transmit data to the display 55. The visible light camera 54 typically integrates artificial intelligence algorithms, which can automatically analyze video streams and achieve automatic fire identification. Please refer to [link to relevant documentation]. Figure 5 When the smoke sensor 51 detects a value exceeding the smoke threshold, the flame sensor 52 sends a fire signal, or the temperature sensor 53 detects a value exceeding the temperature threshold, the visible light camera 54 can accurately locate the fire area.

[0062] In addition, security personnel in fire scenarios can accurately locate the fire area by watching the 55-inch monitor in real time and detecting abnormal flames, thick smoke, or panic among people.

[0063] Preferably, please continue reading. Figure 5This embodiment also includes an alarm structure connected to the control board. For example, the alarm structure includes at least one of a buzzer and a warning light. When the detection value of the smoke sensor 51 exceeds the smoke threshold, the flame sensor 52 emits a fire signal, or the detection value of the temperature sensor 53 exceeds the temperature threshold, the control board is triggered to generate an alarm signal. The control board controls the alarm structure to emit at least one of an audible signal and a visual signal to warn the operator.

[0064] In other feasible embodiments, a feeding interface 211 is installed at the end of the main pipe 21 near the fire interface 12. The feeding interface 211 is connected to the medium conveying pipe, and a regulating valve 6 connected to the control board is installed at the end of the medium conveying pipe near the feeding interface 211. Under normal conditions, the control board opens the regulating valve 6, and the main pipe 21 and branch pipe 22 are used to convey production media such as spraying materials, cleaning agents or gases. Once a fire is detected, the control board closes the regulating valve 6, starts the fire pump, and releases water mist to extinguish the fire. The entire process is automatically judged and executed by the control board, which has closed-loop logic control capability, requires no manual intervention, has a short response time, and high reliability.

[0065] The modular fire protection system provided in this embodiment is designed with modularity, packaged and numbered according to the arrangement sequence, and shipped to enable rapid on-site installation, reducing transportation and storage chaos, improving assembly efficiency, shortening assembly time, and possessing universal expandability. It is suitable for fire protection deployment in high-bay rack storage, painting workshops, cold chain logistics, and automated production line fire protection scenarios, and can achieve intelligent fire protection without human intervention, with high reliability.

[0066] Example 2

[0067] This embodiment provides a modular fire protection system. Based on the structure of Embodiment 1, the fire pump is always in the running state, and the sprinkler heads 23 installed on some branch pipes 22 are closed sprinkler heads. The shut-off valves 31 corresponding to these branch pipes 22 are always in the open state. The closed sprinkler heads have built-in thermal sensors. When the temperature of the fire scene reaches the glass bulb bursting temperature, the closed sprinkler heads can automatically release water mist to extinguish the fire. It should be noted that at this time, the fire pump is in a low pressure state. The closed sprinkler heads monitor the ambient temperature through their built-in thermal sensors and then automatically release water mist. The closed sprinkler head is an existing device in the prior art, and its principle will not be further described here.

[0068] By installing closed-type sprinklers, the sensitivity of fire monitoring can be improved, the fire response time can be shortened, and the reliability of fire protection can be enhanced.

[0069] Further, please refer to Figure 6In this embodiment, an alarm valve is installed on the main pipe 21. The alarm valve is located upstream of any branch pipe 22 and is connected to the control board. The alarm valve is used to monitor in real time whether the main pipe 21 has a continuous flow, that is, whether the closed sprinkler head releases water mist. When the main pipe 21 has a continuous flow, it can trigger the control board to generate an alarm signal. The control board controls the alarm structure to emit at least one of the sound signal and light signal to alert the operator. Furthermore, the control board increases the pressure of the fire pump and increases the water spray volume of the closed sprinkler head to help extinguish the fire quickly.

[0070] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
