Description

Technical Field

[0001] This utility model relates to the technical field of solid-state gas-generating fire suppression devices, and in particular to a solid-state gas-generating driven fire suppression device. Background Technology

[0002] The installed capacity of new energy storage systems is expected to continue to grow in the future. To date, nearly 70 fire incidents related to energy storage systems have occurred globally. With the rapid increase in the number of projects put into operation and the growing scale of individual energy storage projects, the safety hazards of energy storage are also increasing, drawing attention to the safety issues throughout the entire lifecycle of energy storage.

[0003] Currently, energy storage fire suppression devices mainly include nitrogen-pressurized and non-pressurized pump-type devices. Nitrogen-pressurized fire suppression devices utilize gas stored in cylinders to provide pressure, which propels the extinguishing medium through a siphon tube into the pipeline. Although the technical principle is simple and the structure is widely used in heptafluoropropane fire suppression systems, its large size and weight, requiring frequent annual inspections and maintenance, lead to low reliability. Non-pressurized pump-type devices use a pump to pump the extinguishing medium from the container into the pipeline. They are simple in structure, low in cost, and easy to maintain, and can be started and stopped multiple times. However, they have high power consumption, low pump operating pressure, and small nozzle flow rate, making it difficult to achieve the required extinguishing concentration in a short time, and battery-powered fire suppression is almost ineffective.

[0004] For example, invention application number 202311817767.9 discloses a compressed nitrogen foam fire extinguishing device for energy storage power stations. This application utilizes the characteristic of nitrogen as an inert gas, which can inhibit combustion on the surface of burning materials, thus helping to accelerate fire extinguishing. However, it also has the problems of large size and weight, requiring regular annual inspections and frequent maintenance, and low reliability.

[0005] Therefore, there is a real need for a solid-state gas-generating fire suppression device that adopts a solid-state gas-generating drive, has a simple structure, and has the advantages of being maintenance-free, having strong environmental adaptability, and rapid fire extinguishing response.

The sub-box valves are electrically connected to the controller. The sub-box valves are provided with a thin insulating wall between the branch pipe and the main pipe. When gas is generated, the sub-box valves are controlled by the controller and the thin wall is broken through by an electric explosion.

[0016] As a further embodiment of this utility model, the fire extinguishing containers are configured in groups, with each group corresponding to a sub-box valve group, and the sub-box valve groups are connected to each other through a conduit.

[0017] As a further embodiment of this invention, the controller is electrically connected to the field detector;

[0036] The embodiments of this utility model are described in detail below. Examples of these embodiments are illustrated in the accompanying drawings, wherein the same or similar symbols denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0037] Example:

[0038] like Figure 1 As shown, this utility model discloses a solid-state gas-generating fire suppression device, comprising:

[0039] A rectangular box 100 is provided, with handles 120 installed on the opposite side walls of the box 100 to facilitate its movement.

[0040] The side panel of the enclosure 100 is also equipped with a host computer communication connector 130, a field detector connector 150 and a power connector 140, which can be used to electrically connect the host computer, the field detector and the power supply.

[0041] The side panel of the enclosure 100 is also provided with a main pipe interface 160, and the main pipe 110 inside the enclosure 100 is connected to the main pipe at the fire extinguishing site through the main pipe interface 160.

[0042] The top of the housing 100 is provided with a cover 170, which is screwed to the housing 100. The entire housing 100 seals the fire extinguishing container 400 inside the housing 100. The housing 100 can withstand the pressure when the fire extinguishing container 400 accidentally leaks gas, thereby improving the safety and reliability of the device.

[0043] The enclosure 100 can be made of 1.2mm thick Q235 cold-rolled stainless steel sheet. During processing, it adopts machined sheet metal bending and welding technology. While ensuring the strength of the enclosure 100, the internal structure is reinforced and the weight is reduced. The overall weight of the fire suppression device is controlled within a reasonable parameter range. After the product is assembled, the external dimensions are controlled within the range of 709mm in length, 480mm in width, and 300mm in height, and the total weight is controlled within 70kg ± 0.5kg. The whole is modularly designed and can be flexibly adapted to various scenarios.

[0044] The enclosure 100 is equipped with multiple fire extinguishing containers 400 (such as...). Figure 2 (As shown in the diagram, the fire extinguishing container 400 is fixed by the bracket 180, and the bracket 180 is connected to the bottom plate of the box body 100.)

[0045] The fire extinguishing container 400 uses a solid gas generator to produce pressurized gas. The solid gas generator is filled with a liquid, cooling, environmentally friendly fire extinguishing agent (such as perfluorohexanone). The fire extinguishing agent is solid (non-gaseous perfluorohexanone) in a normal temperature and pressure environment. There is no gas inside the fire extinguishing container 400, so no internal pressure is generated, which is beneficial for storage.

[0046] The fire extinguishing container 400 includes an electric ignition head 420, which is electrically connected to a controller 200, such as... Figure 4 As shown, the electric ignition head 420 can be electrically connected to the controller 200 via the plug connector 430, which facilitates maintenance and replacement.

[0047] When gas generation is required, the electric igniter 420 is controlled by the controller 200 to ignite the solid gas extinguishing agent. The gas generator quickly builds up pressure and pushes the piston to rapidly atomize and release the loaded extinguishing agent, thus generating gas and forming a gas-mist mixture extinguishing agent with a concentration that meets the requirements for fire extinguishing, thereby achieving the purpose of fire extinguishing and fire control. After the generated gas is controlled by the distribution box valve group 300, it enters the main pipeline 110 through the branch pipeline 410.

[0048] like Figure 3 As shown, the sub-valve group 300 is used to control the connection and disconnection between the branch pipe 410 and the main pipe 110 of the fire extinguishing container 400. The fire extinguishing containers 400 are configured in groups (e.g., 4 per group), and each group corresponds to one sub-valve group 300. The sub-valve groups 300 are connected to each other through the conductor pipe 320.

[0049] The sub-valve assembly 300 includes sub-valve 310 corresponding to the number of fire extinguishing containers 400. The sub-valve 310 is electrically connected to the controller 200. One end of the sub-valve 310 is connected to the branch pipe 410 leading out from the fire extinguishing container 400, and the other end of the sub-valve 310 is connected to the main pipe 110. Each sub-valve 310 forms a parallel structure through the connecting pipe of the main pipe 110.

[0050] A thin insulating wall is installed between the branch pipe 410 and the main pipe 110. When gas generation is required, the distribution valve 310 is controlled by the controller 200. The distribution valve 310 adopts an electro-explosive method, which generates high-pressure gas at the moment of gunpowder combustion to push the firing pin to break through the thin wall between the branch pipe 410 and the main pipe 110, forming a passage between the branch pipe 410 and the main pipe 110. The fire suppression device pushes the extinguishing agent to the main pipe at the fire scene to achieve the fire extinguishing spray effect.

[0051] like Figure 1 As shown, the controller 200 can be electrically connected to the host computer and field detectors through various connectors, forming a variety of application modes.

[0052] One application uses a host computer, which is electrically connected to both the field detectors and the controller 200. The controller 200 receives instructions from the host computer and controls the fire extinguishing containers 400 and the sub-valve groups 300. For example, based on the fire situation collected by the host computer through the field detectors, if it is necessary to activate two fire extinguishing containers 400 to produce gas, the controller 200 sends an ignition command to the two fire extinguishing containers 400. After ignition, gas production begins, and simultaneously, an electric explosion command is sent to the corresponding sub-valve groups 310 of the two fire extinguishing containers 400, connecting the branch pipes of the two fire extinguishing containers 400 to the main pipe, and outputting gas to the fire extinguishing site pipeline.

[0053] Another application is that the controller 200 directly controls the system based on the signals from the field detectors. The controller 200 makes its own judgment and sends an ignition command to the fire extinguishing container 400 and an electric explosion command to the corresponding compartment valve 310.

[0054] In the above structure, the control signals for the electric ignition head 420 and the electric explosion of the distribution valve 310 are separated, so that the fire extinguishing container 400 is doubly protected, avoiding accidental output of gas to the fire extinguishing site pipeline.

[0055] Furthermore, branch pipe 410 and main pipe 110 are made of steel wire braided hoses to ensure that they can withstand the high pressure generated by the extinguishing agent spray, while also allowing for flexible arrangement of the fire extinguishing network according to the internal space of the box 100.

[0056] Furthermore, the fire extinguishing container 400 is equipped with a pressure sensor, which is used to measure the internal pressure of the fire extinguishing container 400. The pressure sensor is electrically connected to the controller 200, and the pressure sensor signal can be sent to the controller 200 or the host computer for display, so as to facilitate the monitoring of the internal pressure of the fire extinguishing container 400.

[0057] When this device is in use, multiple fire suppression devices are connected to the energy storage container fire extinguishing system. The interfaces of the sub-valve 310 of the multiple fire suppression devices are connected to the main fire extinguishing pipe, thus becoming part of the energy storage fire prevention and control system.

[0058] The fire suppression device has a built-in controller 200. After receiving data from the fire scene detectors or receiving instructions from the host computer, the controller 200 outputs corresponding control commands.

[0059] Upon receiving the command, the fire extinguishing container 400 ignites, and the gas generator quickly builds up pressure to push the piston, rapidly atomizing and releasing the filled extinguishing agent to form a gas-mist mixture extinguishing agent with the required concentration for fire extinguishing. The sub-valve 310 uses an electro-explosion method, where the high-pressure gas generated by the combustion of gunpowder pushes the firing pin to break through the thin wall between the main pipe 110 and the branch pipe 410, creating a passage. Based on the location and level of the detector in the thermal runaway battery box, the sub-valve 310 is selectively opened to connect the branch pipe 410 to the main pipe 110, pushing the extinguishing agent to the main pipe of the fire extinguishing system to achieve the fire extinguishing spray effect.

[0060] Under normal conditions, the fire suppression device has no storage pressure in the fire extinguishing container 400, making it safe and reliable. After the start switch gives the start signal, the gas generator acts quickly, and within 1 second, the extinguishing agent is rapidly sprayed out of the fire extinguishing container 400 through the piston movement principle. Within 5 seconds, an effective extinguishing concentration is formed, achieving the effect of rapid fire extinguishing and cooling of the thermal runaway energy storage lithium battery.
