[0002] The energy storage industry often requires fire suppression devices to prevent the negative impact of fires in energy storage packs. For lithium-ion battery packs, existing fire suppression systems often lack pumps. Or, if pumps are included, the fire extinguishing agent relies entirely on the tightness of a one-way valve or ball valve. Valve connections not only present a risk of leakage, but solenoid-operated ball valves also require a controller to control their opening and closing, increasing control logic risks. Furthermore, the fire extinguishing agent can easily enter the pump, corroding its internal components. This reduces the fire suppression effectiveness and poses a high risk of use.

[0026] The following describes the embodiments with reference to the accompanying drawings, which do not limit the application content described in the claims.

[0027] This specification provides method operation steps such as embodiments or flow charts, but based on routine or non-creative work, more or fewer operation steps may be included. The order of steps listed in the embodiments is only one way of executing the steps among many, and does not represent the only execution order.

[0028] The present application provides a fire suppression device, which is particularly suitable for scenarios where a fire occurs in a lithium-ion battery pack.

[0029] Please refer to Figure 1-Figure 2The present embodiment provides a fire suppression device comprising a fire extinguishing agent container 2 and a vertical multistage pump 1. The fire extinguishing agent container 2 is used to contain the fire extinguishing agent. The vertical multistage pump 1 comprises a suction port 11 and a discharge port 12. The discharge port 12 is higher than the fire extinguishing agent container outlet 21. The suction port 11 is disposed within the fire extinguishing agent container 2 and is located near the bottom of the fire extinguishing agent container 2. By selecting a vertical multistage pump with a discharge port higher than the fire extinguishing agent container outlet, the overall structure of the fire suppression device is simplified, valves are eliminated, and assembly of the fire suppression device is simple and quick. This prevents fire extinguishing agent from remaining in the vertical multistage pump, thereby improving the effectiveness of suppressing fires.

[0030] Specifically, the fire suppression device is integrated into the thermal management system, and the fire suppression device is connected to the battery pack.

[0031] Understandably, a fire suppression device is a device designed to suppress fires in lithium-ion battery packs used for energy storage. It uses a pump to spray a fire extinguishing agent toward the point of ignition. The extinguishing process involves both physical cooling and chemical inerting. As the extinguishing agent is released, it rapidly transforms from a liquid to a gaseous state. At the flame front, the agent absorbs heat and decomposes, absorbing a significant amount of heat, rapidly lowering the fire temperature and thus suppressing the spread of flames. During the extinguishing process, the extinguishing agent continuously reacts chemically with hydrogen (H+) generated by the fire, forming HF, which in turn blocks the spread of the fire.

[0032] Specifically, the vertical multistage pump 1 includes a pump casing, multiple impellers, a guide vane, a pump shaft, a motor 13, an intake port 11, and an exhaust port 12. Multiple impellers are connected in series, each with corresponding guide vanes. The guide vane is located between the impellers, directing the flow and reducing energy loss. The pump shaft connects the motor 13 to the impellers, transmitting power. Bearings support the pump shaft, ensuring smooth rotation. The motor 13 provides power to the pump, driving the pump shaft.

[0033] Specifically, the fire extinguishing agent container 2 is used to hold fire extinguishing agent. Different application scenarios correspond to different specifications of the fire extinguishing agent container 2. When the fire extinguishing agent container 2 is not used for fire extinguishing, the fire extinguishing agent container 2 contains less than 90% of the fire extinguishing agent to prevent excessive overflow of the fire extinguishing agent. The inner cavity of the fire extinguishing agent container 2 is provided with a corrosion-resistant coating.

[0034] In this embodiment, the vertical multistage pump 1 is arranged at the outlet of the fire extinguishing agent container 2, that is, the vertical multistage pump 1 is connected to the fire extinguishing agent container 2, and the outlet of the fire extinguishing agent container 2 is located between the suction port 11 and the discharge port 12 of the vertical multistage pump 1.

[0035] Specifically, the fire extinguishing agent container outlet 21 and the liquid filling port 23 are located on the same outer wall.

[0036] Furthermore, the vertical multi-stage pump 1 includes a motor 13, which is disposed between the discharge port 12 and the fire extinguishing agent container outlet 21. This prevents the motor 13 from coming into contact with the fire extinguishing agent, improving the reliability of fire suppression. The proximity of the motor 13 to the pump inlet and outlet also reduces the path of the fluid before it enters the motor 13, thereby reducing flow losses and improving the overall operating efficiency of the pump.

[0037] Specifically, the vertical multi-stage pump 1 is connected to a power supply, which provides driving force for the motor 13 , which in turn drives the impeller and guide vanes to pump the fire extinguishing agent from the fire extinguishing agent container 2 . The power supply also provides a driving source for the control device 3 .

[0038] In one embodiment, the vertical multi-stage pump 1 is further connected to a backup power supply 4 . If the power supply is cut off, the backup power supply 4 is turned on to supply power to the vertical multi-stage pump 1 .

[0039] Furthermore, the fire suppression device includes a liquid level sensor 22, which is disposed within the fire extinguishing agent container 2 and is connected to the vertical multi-stage pump 1. In this manner, the liquid level sensor 22 can monitor the liquid level within the fire extinguishing agent container 2 in real time, ensuring an adequate supply of fire extinguishing agent and promptly detecting low liquid levels, thereby avoiding fire extinguishing failures due to insufficient fire extinguishing agent when a fire occurs. After the liquid level sensor 22 is connected to the vertical multi-stage pump 1, it can automatically control the start and stop of the pump based on changes in the liquid level. When the liquid level falls below a set value, the liquid level sensor 22 can send a signal to automatically start the pump, preventing the vertical multi-stage pump 1 from operating when the fire extinguishing agent level is insufficient, thereby preventing dry running and extending the service life of the pump.

[0040] In one embodiment, the liquid level sensor 22 is disposed on the inner wall of the fire extinguishing agent container 2 , and the liquid level sensor 22 is used to monitor the liquid level of the fire extinguishing agent inside the fire extinguishing agent container 2 in real time.

[0041] Optionally, the liquid level sensor 22 may be a resistive liquid level sensor 22 , a float-type liquid level sensor 22 , or a pressure-type liquid level sensor 22 .

[0042] Specifically, when the liquid level is lower than a set threshold, the liquid level sensor 22 will generate an alarm signal, which is transmitted to the control system of the fire suppression device, thereby reminding the operator to add liquid.

[0043] Specifically, when the liquid level is lower than a set threshold, the fire extinguishing agent flows into the fire extinguishing agent container 2 from the liquid filling port 23 .

[0044] The fire suppression system further includes a control device 3 connected to the vertical multi-stage pump 1 and configured to start and stop the vertical multi-stage pump 1. The control device 3 automatically starts and stops the vertical multi-stage pump 1 in response to detected fire signals, thereby rapidly activating the fire extinguishing system. The control device 3 enables remote monitoring and control, allowing operators to start and stop the pump from a safe location, enhancing safety. Safety switches and logic can be configured through the control device 3 to prevent accidental pump startup in the absence of a fire, ensuring the proper operation of the pump and system.

[0045] In this embodiment, when the vertical multistage pump 1 is turned on, the fire extinguishing agent is ejected from the fire extinguishing agent container 2; when the vertical multistage pump 1 is turned off, part of the fire extinguishing agent in the vertical multistage pump 1 flows back into the fire extinguishing agent container 2 from the vertical multistage pump 1 under the action of gravity, so that the fire extinguishing agent will not corrode the vertical multistage pump 1.

[0046] Furthermore, the fire suppression device further includes a fire detector, which is connected to the control device 3. In this way, the fire detector can monitor smoke, temperature or flames in real time, and issue an alarm as soon as a fire is detected, immediately transmitting a signal to the control device 3 to start the vertical multi-stage pump 1.

[0047] Specifically, the fire detector includes a temperature detector 5 and / or a smoke detector 6, which are connected to the control device 3. The temperature detector 5 and / or the smoke detector 6 are set within a preset range so that the temperature detector 5 and / or the smoke detector 6 can detect the status of each battery pack 8.

[0048] In one embodiment, the control device 3 is connected in parallel with the temperature detector 5 and the smoke detector 6 respectively. If the temperature detector 5 is damaged, the smoke sensor can continue to monitor the status of the battery pack 8.

[0049] Specifically, when the signal detected by one of the temperature detector 5 and the smoke detector 6 exceeds a set threshold, a signal is transmitted to the control device 3 to start the vertical multi-stage pump 1 .

[0050] Furthermore, the vertical multistage pump 1 includes a sealing disc, and the fire extinguishing agent container 2 includes a quick connector, and the sealing disc is connected to the quick connector. Thus, the quick connector design of the vertical multistage pump 1 and the fire extinguishing agent container 2 enables the fire suppression device to be quickly connected and disassembled. The design of the sealing disc can effectively prevent the fire extinguishing agent from leaking at the connection point, ensuring the safe storage and use of the fire extinguishing agent. The multistage pump operates under high pressure, and the combination of the sealing disc and the quick connector can effectively withstand high-pressure environments and ensure the safe operation of the system. The standardized design of the quick connector makes the vertical multistage pump 1 compatible with a variety of fire extinguishing agent containers 2, adapting to different fire extinguishing needs.

[0051] Specifically, the sealing disc and the quick connector are connected using fasteners, and the sealing disc is provided with a plurality of fastener through holes, thereby fixing the vertical multi-stage pump 1 and the fire extinguishing agent container 2 in connection.

[0052] Specifically, the fire suppression device also includes a sealing gasket disposed between the sealing disc and the quick connector. This gasket fills the tiny gap between the sealing disc and the quick connector, preventing leakage of the fire extinguishing agent under high pressure. The gasket also adapts to the shapes of different contact surfaces, enhancing the overall sealing effect. The gasket also serves to reduce vibration and noise generated during operation of the vertical multi-stage pump 1, thereby extending the service life of the equipment.

[0053] Specifically, the size of the sealing gasket matches the sealing disk, and the sealing gasket is made of corrosion-resistant and high-temperature-resistant materials.

[0054] Specifically, during the installation of the vertical multi-stage pump 1 , the sealing gasket is first matched with the quick connector, and then the sealing disc is matched with the sealing gasket, thereby improving the sealing effect between the vertical multi-stage pump 1 and the fire extinguishing agent container 2 .

[0055] In one embodiment, the sealing gasket is made of EPDM.

[0056] Furthermore, the vertical multi-stage pump 1 also includes a filter screen connected to the suction port 11. By adding the filter screen to the vertical multi-stage pump 1 and connecting it to the suction port 11, the filter screen effectively captures solid impurities, particles, and sediment in the fire extinguishing agent, preventing them from entering the pump body, thereby protecting the impeller and bearings of the vertical multi-stage pump 1, reducing wear, and improving the fire extinguishing effect.

[0057] Specifically, the filter screen is made of stainless steel, and one or more filter screens are provided. If the suction port 11 includes multiple filter screens, the filter screens are evenly provided.

[0058] In one embodiment, the discharge port 12 is connected to at least one firefighting pipe. In this way, the firefighting pipe connected to the discharge port 12 can quickly provide fire extinguishing agent in the event of a fire. By providing multiple connection points between the firefighting pipe and the discharge port 12, the fire extinguishing agent can be flexibly allocated to improve the firefighting efficiency.

[0059] Specifically, if the discharge port 12 is connected to a plurality of fire-fighting pipelines, the plurality of fire-fighting pipelines are connected in parallel, and each fire-fighting pipeline corresponds to a respective battery pack 8 .

[0060] In one embodiment, the fire protection pipe is connected to the fire sprinkler 7. The direct connection between the fire protection pipe and the fire sprinkler 7 ensures that the fire extinguishing agent can quickly extinguish the fire source when a fire occurs. The fire extinguishing agent is sprayed through the fire sprinkler 7, and the fire extinguishing agent can evenly and effectively cover the fire area, thereby enhancing the fire extinguishing effect.

[0061] Specifically, if the fire-fighting pipeline is directly connected to the fire-fighting sprinkler 7, the fire-fighting sprinkler 7 corresponds to different spraying modes, which may include an aerosol spraying mode, a fine mist spraying mode or a large flow spraying mode. Based on different scenarios, the fire-fighting sprinkler 7 selects different spraying modes.

[0062] In this embodiment, the fire protection pipelines are connected to the fire protection sprinklers 7 , and each fire protection pipeline corresponds to its own fire protection sprinkler 7 , so as to improve the fire suppression effect.

[0063] In another embodiment, the fire sprinkler head 7 is directly connected to the discharge outlet 12 .

[0064] The following describes the working process of the fire suppression device in the embodiment of the present application in combination with specific application scenarios, as follows:

[0065] First, the temperature detector 5 and / or the smoke detector 6 detects a fire signal and transmits the fire signal to the control device 3;

[0066] Then, the control device 3 controls the vertical multistage pump 1 to open, and the fire extinguishing agent is transferred from the fire extinguishing agent container 2 through the suction port 11 of the vertical multistage pump 1 to between the multiple impellers and the multiple guide vanes, and then discharged through the discharge port 12 of the vertical multistage pump 1;

[0067] Finally, the fire extinguishing agent is delivered from the discharge port 12 to a plurality of fire fighting pipes arranged in parallel and then sprayed out through the nozzles, and the fire extinguishing agent covers the corresponding battery packs 8 .

[0068] Through the above steps, the fire suppression device can quickly and accurately suppress the fire of the battery pack 8.

[0069] The following describes specific embodiments of the present application based on the above technical solutions.
