Description

Technical Field

[0001] This utility model relates to the field of battery technology, specifically to a fire protection system for static storage warehouses. Background Technology

[0002] Fire safety is a crucial aspect of modern warehousing and industrial facilities. To effectively respond to fires, many companies employ various fire protection solutions to ensure the safety of personnel and property. Fire safety requirements are paramount, especially for battery storage warehouses.

[0003] Currently, the fire protection solution for static storage warehouses is to equip each storage location with a temperature sensor and a fire detector. The temperature sensor monitors temperature changes, and the fire detector provides a rapid response, enabling timely detection and extinguishing of fires in their early stages.

[0004] However, with the expansion of warehouse scale and the diversification of stored goods, existing fire protection solutions have gradually revealed some shortcomings. Specifically, fire detection tubes are expensive, increasing the company's operating costs; the configured 1230 fire extinguishing agent can only maintain fire suppression for about 2 minutes; if the fire exceeds this time, it will not be effectively extinguished, posing a risk of reignition; in addition, the existing solution relies on an electronic control system to trigger the fire extinguishing device, and if the control system malfunctions, it may affect the fire suppression effect and increase the fire risk. Utility Model Content

[0005] In view of this, the present invention provides a fire protection system for static warehouses to solve the problem of low reliability of fire protection systems for static warehouses.

[0006] This utility model provides a fire protection system for static storage warehouses, including multiple static storage warehouses and a fire protection system. The multiple static storage warehouses are stacked along their height, and the warehouses are suitable for storing batteries. The fire protection system includes a main water inlet pipe, a distribution pipe, multiple distribution branch pipes, and multiple self-starting sprinkler heads. The distribution pipes are connected to the main water inlet pipe and extend from bottom to top. At least one self-starting sprinkler head is installed at the top of each static storage warehouse, and each sprinkler head is connected to the distribution pipe via a distribution branch pipe.

[0007] Beneficial effects: The static warehouse fire protection system provided in this embodiment of the utility model is used for fire protection of static warehouses. It does not require an electronic control system, realizes automatic sprinkler system, rapid response, and efficient fire extinguishing. Because the fire water supply is sufficient, it can be triggered immediately and continuously suppress the fire after it occurs, which can avoid the situation where the fire reignites after the gas fire extinguisher runs out of gas cylinders, and at the same time reduce the construction cost.

[0013] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0014] The existing fire protection scheme has the following problems:

[0015] First, fire detection tubes, as high-end fire detection devices, have high production and maintenance costs, leading to significant economic pressure for enterprises when deployed on a large scale. Second, while 1230 fire extinguishing agent has highly efficient fire-extinguishing capabilities, its limited capacity makes it difficult to cope with prolonged fires, especially in large warehouses where fires may last for extended periods, and the agent cannot be used to continue extinguishing the fire once it is depleted. Finally, existing fire protection solutions rely on complex electronic control systems, which may have points of failure in actual operation. A malfunction will directly affect the fire-extinguishing effect. Furthermore, electronic control systems require regular maintenance and inspection, increasing the enterprise's operating costs.

[0016] In summary, while existing fire protection solutions can meet basic fire protection needs to a certain extent, they have significant shortcomings in terms of cost, chemical limitations, and system complexity. A more efficient and reliable fire protection solution is urgently needed to address these issues. The technical solution provided by this utility model adopts a fully automatic water sprinkler fire protection system, which does not require an electronic control system. It can not only immediately trigger and continuously suppress fires, but also effectively prevent reignition of fires caused by the depletion of the 1230 gas cylinders. Simultaneously, it reduces construction costs and improves the overall fire safety level.

[0017] The following is combined with Figures 1 to 2 The following describes embodiments of the present invention.

[0018] According to an embodiment of this utility model, a fire protection system for storage tanks is provided, including multiple storage tanks 1 and a fire protection system 2. The multiple storage tanks 1 are stacked along their height, and the storage tanks 1 are suitable for storing batteries. The fire protection system 2 includes a main water inlet pipe 21, a distribution pipe 22, multiple distribution branch pipes 23, and multiple self-starting sprinkler heads 24. The distribution pipes 22 are connected to the main water inlet pipe 21 and extend from bottom to top. At least one self-starting sprinkler head 24 is provided at the top of the receiving cavity of each storage tank 1, and the self-starting sprinkler heads 24 are respectively connected to the distribution pipes 22 through the distribution branch pipes 23.

[0019] The static warehouse fire protection system provided in this embodiment is used for fire protection of static warehouse 1. It does not require an electronic control system, but achieves automatic sprinkler system, rapid response, and efficient fire suppression. Because the fire water supply is sufficient, it can be triggered immediately and continuously suppress the fire after it occurs, avoiding the situation where the fire reignites after the gas cylinders (1230) are depleted, and also reducing the cost of infrastructure construction.

[0020] Specifically, the static storage 1 is a five-sided fireproof structure, and each static storage 1 is relatively independent. Even if a fire occurs in one static storage 1, it can be effectively isolated to prevent the fire from spreading to other static storage 1s.

[0021] The main water inlet pipe 21 of the fire protection system 2 is connected to a water source for fire water supply, and supplies water to the individual automatic sprinkler heads 24 through the distribution pipe 22 and multiple distribution branch pipes 23. The nozzles of the automatic sprinkler heads 24 are sealed by a heat-sensitive element (usually a glass bulb or fusible alloy), which senses the ambient temperature. When the ambient temperature reaches a set threshold, the heat-sensitive element ruptures or melts, causing the nozzles to open and water to spray out, covering the fire area for cooling and fire extinguishing. No manual intervention is required, and no fire detectors or smoke detectors are needed; it can automatically activate in the early stages of a fire, quickly controlling the fire. By installing automatic sprinkler heads 24 in each static storage unit 1, distributed on the top of each unit, high temperatures can be quickly detected in the early stages of a fire, and water can be automatically sprayed to extinguish the fire in time and prevent its spread. Batteries are stored in the static storage unit 1; in the event of a fire, the automatic sprinkler heads 24 can activate quickly, reducing the risk of battery explosion and protecting personnel and property. Each storage warehouse 1 is equipped with at least one self-activating sprinkler head 24 to ensure effective protection of the entire warehouse area without any blind spots. Furthermore, each storage warehouse 1 and its fire protection system 2 are relatively independent, facilitating daily inspection and maintenance and reducing the overall system failure rate. The clear layout of each self-activating sprinkler head 24 via a water distribution branch pipe 23 facilitates regular inspection and replacement, ensuring the system is always in good working order. The efficient fire protection system 2 can reduce fire losses, lower insurance costs, and improve overall economic efficiency.

[0022] Specifically, in this utility model, "multiple" includes two.

[0023] Specifically, in this embodiment, the self-starting sprinkler head 24 is a temperature-sensitive glass bulb sprinkler head. The temperature-sensitive glass bulb sprinkler head has a built-in temperature-sensitive glass bulb structure, the inside of which is filled with a low-melting-point alloy or liquid. When the ambient temperature reaches a preset temperature (typically 68°C, 93°C, etc.), the material inside the glass bulb expands due to heat, causing the glass bulb to break. After the glass bulb breaks, the sealed sprinkler head opens, and water is sprayed out through the sprinkler head, covering the fire area and extinguishing the fire.

[0024] Specifically, the water distribution pipe 22 is located outside the settling tank 1, one end of the water distribution branch pipe 23 is connected to the water distribution pipe 22, and the other end of the water distribution branch pipe 23 extends to the top inside the settling tank 1. At the same time, a self-starting sprinkler head 24 is connected to the end of the water distribution branch pipe 23.

[0025] In some alternative embodiments, the fire protection system 2 also includes an automatic air vent 25 located at the top of the water distribution pipe 22.

[0026] By installing an automatic air vent valve 25 at the top of the water distribution pipe 22, air in the pipe can be automatically vented, preventing air accumulation at the highest point of the pipe. Air accumulation can lead to unstable water pressure in the pipe, affecting the normal operation of the sprinkler heads. By venting air, stable water pressure in the pipe is ensured, thereby guaranteeing that each self-starting sprinkler head 24 receives sufficient water pressure, improving the fire extinguishing effect. Simultaneously, air bubbles can interfere with the water flow, affecting its uniformity and continuity. The automatic air vent valve 25 effectively reduces these bubbles, ensuring smooth water flow. Air-free water can reach the sprinkler heads faster, improving the system's response speed to fires and enhancing the reliability of the fire protection system 2. Furthermore, the automatic air vent valve 25 reduces cavitation, protecting system equipment. In addition, the automatic air vent valve 25 requires no manual intervention, automatically venting air from the pipe and simplifying system maintenance.

[0027] In some alternative embodiments, the top of the water distribution pipe 22 is higher than the topmost settling tank 1.

[0028] In some optional embodiments, the main water inlet pipe 21 is located below the bottommost static storage tank 1; the main water inlet pipe 21 includes a main control section 211 and a distribution section 212, and the water distribution pipe 22 is connected to the distribution section 212 of the main water inlet pipe 21; the fire protection system 2 also includes a control valve 26, which is located in the main control section 211 of the main water inlet pipe 21.

[0029] Specifically, along the water supply direction, the distribution section 212 of the main inlet pipe 21 is located downstream of the main control section 211 of the main inlet pipe 21. By installing a control valve 26 in the main control section 211 of the main inlet pipe 21, the water supply of the entire fire protection system 2 can be managed, facilitating rapid response to fire situations. After opening the control valve 26, fire water enters the main inlet pipe 21, putting the fire protection system of the static storage tank into a standby state.

[0030] The main water inlet pipe 21 is located below the bottommost static storage tank 1, which facilitates centralized management and maintenance and reduces the complexity of pipe layout.

[0031] In some alternative embodiments, the fire protection system 2 also includes a water flow indicator 27, which is located in the main control section 211 of the main water inlet pipe 21 and is located downstream of the control valve 26 along the water flow direction.

[0032] A water flow indicator 27 is installed downstream of the control valve 26 via the main control section 211 of the main water inlet pipe 21. This allows for real-time monitoring of the water flow in the main water inlet pipe 21, enabling rapid detection of changes in water flow and ensuring timely water supply in the early stages of a fire. This improves system response speed and firefighting efficiency. Simultaneously, the data provided by the water flow indicator 27 allows for more precise water flow control, ensuring sufficient water pressure for each sprinkler head and enhancing firefighting effectiveness.

[0033] In some alternative embodiments, the fire protection system 2 also includes a drain valve 28 located at the end of the main water inlet pipe 21.

[0034] After the fire suppression system in the static warehouse has been used for fire extinguishing, opening the drain valve 28 can accelerate the drainage of residual water in all fire pipes, facilitate the replacement of the self-starting sprinkler head 24, and improve operational efficiency.

[0035] In some optional embodiments, a mounting rack 3 is also included, which includes a plurality of storage units 31 arranged side by side, each storage unit 31 having multiple layers of shelves along the height direction, and a static storage 1 being located on one shelf.

[0036] The mounting rack 3 adopts a multi-layer shelving design, which can make full use of vertical space, reduce the floor area, and improve the space utilization rate of the warehouse. Multiple storage units 31 are arranged side by side, and the number and layout of the mounting rack 3 can be flexibly adjusted according to actual needs to adapt to different warehousing requirements. Each rack can be used to store different static storage units 1, and adjacent static storage units 1 are independent of each other. In the event of a fire in one static storage unit 1, the impact on other static storage units 1 is reduced.

[0037] Specifically, Figure 1 The area indicated by the dashed box is a storage unit 31. Figure 1 The CCP has six storage units, number 31.

[0038] In some alternative embodiments, two storage units 31 constitute a fire-fighting group, with at least one fire-fighting group distributed along the X direction, and a water distribution pipe 22 is configured within the fire-fighting group, with the water distribution pipe 22 located between the two storage units 31.

[0039] This configuration significantly reduces the amount of piping used, lowering material costs. Simultaneously, reducing the number of pipes simplifies the installation process, saving installation time and labor costs. Furthermore, the shared water distribution pipe 22 reduces the number of pipe joints, lowering the risk of malfunctions due to leaks or loosening at joints. In addition, the shared water distribution pipe 22 reduces the space occupied by piping, making the warehouse layout more compact and rational, improving space utilization. Finally, the shared water distribution pipe 22 ensures that water pressure and flow are evenly distributed among the various storage units 31, improving the overall efficiency of the system.

[0040] By optimizing the pipe layout and sprinkler head configuration, unnecessary redundant equipment was reduced, thereby lowering construction and operating costs.

[0041] Specifically, such as Figure 1 As shown, two adjacent storage units 31 form a fire protection group, sharing a single water distribution pipe 22. In the static storage compartments 1 on both sides of the water distribution pipe 22, water distribution branch pipes 23 supplying water to the self-starting sprinkler heads 24 are all connected to the water distribution pipe 22.

[0042] In some optional embodiments, the fire protection system 2 also includes an end test pipe 29 and an end test device 210. Along the water supply direction, one end of the end test pipe 29 is connected to the end of the water distribution pipe 22 in the unpositioned position, and the other end of the end test pipe 29 extends to the operating position. The end test device 210 is connected to the other end of the end test pipe 29.

[0043] By setting up the end test pipe 29 and the end test device 210, the water pressure of the system can be tested during the acceptance of the fire protection system of the static warehouse.

[0044] The end test pipe 29 and the end test device 210 can be used to periodically test the water pressure and flow rate of the fire protection system 2 to ensure that the system can work properly when needed. The end test device 210 can be used to verify the functionality of the self-starting sprinkler head 24 and other fire protection equipment, and to promptly identify and repair potential problems.

[0045] Regular testing and data logging allow for the early detection of potential problems, enabling preventative measures to be taken, reducing system failures, and improving system reliability. Regular testing ensures system performance during critical moments, enhancing system reliability and responsiveness.

[0046] The other end (i.e., the end) of the end test pipe 29 extends to the operating position, and the end test device 210 is connected to the end of the end test pipe 29 for easy operation. Through the end test device 210, tests can be performed without affecting the normal operation of the system, reducing system downtime.

[0047] In some optional embodiments, multiple self-starting spray heads 24 are arranged at intervals along the depth extension direction of the static storage tank 1.

[0048] Multiple self-activating sprinkler heads 24 are spaced apart along the depth of the static storage room 1. This ensures that in the event of a fire, the sprinkler heads 24 can cover every corner of the static storage room 1, reducing blind spots and improving fire suppression effectiveness. Simultaneously, multiple sprinkler heads 24 can activate at the same time, responding quickly to a fire, shortening fire suppression time, and reducing fire damage. Rapid and effective fire suppression reduces the threat of fire to personnel and equipment, improving overall safety. Furthermore, the multiple sprinkler heads provide redundancy; even if one sprinkler head 24 fails, others can still operate normally, ensuring system reliability. Finally, the spaced sprinkler heads ensure a continuous supply of fire-fighting water even during prolonged fires, enhancing the system's sustained fire suppression capability.

[0049] Specifically, the number and location of the self-starting sprinkler heads 24 in each static storage 1 are determined based on the spray range of the self-starting sprinkler heads 24 and the actual fire extinguishing needs.

[0050] In some optional embodiments, the static storage 1 includes five fireproof panels that enclose a rectangular fireproof area with an opening on one side for placing and removing batteries. A self-starting sprinkler head 24 is located at the top of the rectangular fireproof area.

[0051] Five fireproof panels enclose a rectangular fireproof area with an opening on one side, effectively isolating external fire sources and preventing the fire from spreading to the adjacent static storage warehouse 1. The combination of the five-sided fireproof structure and the self-activating sprinkler heads 24 provides multiple layers of protection, ensuring rapid and effective fire suppression in the event of a fire, preventing the fire from spreading and reducing fire losses.

[0052] The opening on one side makes it easy to put in and take out the battery.

[0053] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
