Description

Technical Field

[0001] This invention relates to the field of fire extinguishing components technology, and particularly to fire extinguishing components for energy storage containers. Background Technology

[0002] A new round of energy revolution, characterized by the large-scale development and utilization of new energy sources and fundamentally driven by re-electrification, has begun globally. The increasing proportion of renewable energy, represented by wind and solar power, presents numerous challenges to the power system, including issues related to system stability, reliability, and power quality. Energy storage technology is an effective means to address these problems. Large-scale energy storage power stations can store and release electrical energy, providing various services to the power grid, such as peak shaving, frequency regulation, black start, and demand response support. Their rapid response characteristics significantly improve the flexibility, economy, and security of traditional power systems. Furthermore, large-scale energy storage power stations can be widely used in industrial parks, data centers, intercity rail transit, photovoltaic charging stations, hospitals, and other social settings. However, energy storage containers often require the use of fire suppression systems for safe operation.

[0003] For example, application number CN202111293229.5 discloses a fire-fighting device and method for a containerized energy storage system. The fire-fighting device for the containerized energy storage system includes: a detection component for detecting the temperature and voltage of the battery cells in the battery pack, the concentration of smoke inside the container, and the concentration of hydrogen gas inside the battery pack; an alarm component capable of issuing alarm signals when a single or multiple fire alarms occur in the containerized energy storage system; a gas tank capable of spraying fire-fighting gas into the battery pack when a multiple fire alarm occurs; an exhaust system installed on the container; and a fire-fighting water system installed on the container and connected to a water source to inject water into the container when all the fire-fighting gas in the gas tank has been discharged. The fire-fighting device for the containerized energy storage system disclosed in this invention can operate according to the severity of the fire, reducing the possibility of false alarms causing damage to the battery system.

[0004] Existing fire extinguishing components for energy storage containers often employ a single, densely packed fire extinguishing structure. When encountering a localized fire source, this results in the entire container spraying fire extinguishing material, causing unburned areas to become damp. This can affect the stable operation of subsequent equipment inside the container, leading to economic losses. Therefore, this application provides a fire extinguishing component for energy storage containers to meet this need. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide an energy storage container fire extinguishing assembly to solve the problems of existing DD (fire suppression) systems.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0007] A fire extinguishing assembly for an energy storage container includes a main body and a monitoring mechanism. A fire extinguishing mechanism for spraying is located on the upper inner side of the main body. The monitoring mechanism for active air intake is located at the front end of the fire extinguishing mechanism. The fire extinguishing mechanism includes a mounting base and a rotating screw. An electric actuator is mounted on the upper surface of the mounting base, and a movable frame is located at the front end of the electric actuator. A limit rail is located on one side of the upper part of the movable frame. A guide groove is formed in the middle of the surface of the mounting base, and a guide plate is located at the front end of the inner side of the guide groove. A connecting plate is connected to the front end of the guide plate, and a spray head is located in the middle of one side of the connecting plate. The rotating screw is located on the upper rear side of the mounting base, and a geared motor is mounted on the input end of the rotating screw.

[0008] Furthermore, the movable frame is slidably connected to the mounting base via an electric push cylinder and a limiting slide rail, and the limiting slide rail is fixedly connected to the mounting base. The guide plate is slidably connected to the guide groove via the movable frame, and the guide plate and the connecting plate are rotatably connected to the movable frame via the guide groove.

[0009] Furthermore, the monitoring mechanism includes a fixed cover and a mating toothed groove. An air intake fan is provided inside the lower part of the fixed cover, and the mating toothed groove is located on one side above the air intake fan.

[0010] Furthermore, a pressing tooth plate is engaged on one side of the mating tooth groove, and a first turning screw wheel is fixed on the outer side of the pressing tooth plate.

[0011] Furthermore, a smoke sensor is provided inside the upper part of the fixed cover, and a second turning wheel is provided on one side above the smoke sensor.

[0012] Furthermore, a gas replacement mechanism is provided on one side of the inner wall of the main body box, and the replacement mechanism includes an air inlet pipe and a gas guide pipe. A solenoid valve is installed in the middle of the air inlet pipe, and the gas guide pipe is connected to the front end of the air inlet pipe.

[0013] Furthermore, the front surface of the air guide tube is connected to an air distribution tube, and an air outlet is installed on one side of the surface of the air distribution tube.

[0014] Furthermore, a one-way valve pipe is installed above the main body box, and the one-way valve pipe is in communication with the main body box.

[0015] Furthermore, a composite mechanism for assembly and connection is provided on the other side of the inner wall of the main body box. The composite mechanism includes a heat insulation layer and a flame retardant layer, with the flame retardant layer disposed on one side of the surface of the heat insulation layer.

[0016] Compared with the prior art, the present invention has at least the following beneficial effects:

[0017] In the above scheme, the spray head is equipped with a liquid supply tank at its input end, which can spray liquid to extinguish fire in the event of a fire. The sprayed liquid medium is perfluorohexanone + water cluster to enhance the effect. Continuous intermittent spraying inside the container achieves the purpose of cooling and preventing reignition. Through the adjustment and coordination between the fire extinguishing mechanism structures, when encountering local fire sources inside the container, it can make local adjustments to disperse the fire and extinguish it locally, so that the areas that have not caught fire will be sprayed and become damp. This ensures the stable use of subsequent equipment inside the container and avoids certain economic losses.

[0018] The smoke sensor can monitor the situation inside the chamber to facilitate subsequent fire extinguishing. The air intake fan can actively draw air from inside the chamber into the smoke sensor, thereby speeding up the response and shortening the fire extinguishing time, which helps to prevent the disaster from spreading. The tight fit between the squeezing tooth plate and the mating tooth groove allows for easy and quick loading and unloading, making it convenient for maintenance and replacement during use to ensure the safety inside the chamber.

[0019] By using the exhaust mechanism, the air inside the chamber can be replaced, thereby blocking the oxygen required for combustion. The combination of the heat insulation layer and the flame-retardant layer can further improve the effectiveness of fire extinguishing and enhance the safety of the chamber.

[0035] like Figure 1 and Figure 2 As shown, an embodiment of the present invention provides a fire extinguishing assembly for an energy storage container, including a main body 1 and a monitoring mechanism 3. A fire extinguishing mechanism 2 for spraying is provided on the upper inner side of the main body 1. The fire extinguishing mechanism 2 includes a mounting base 201 and a rotating screw 209. An electric actuator 202 is mounted on the upper surface of the mounting base 201, and a movable frame 203 is provided at the front end of the electric actuator 202. A limit rail 204 is provided on one side of the upper part of the movable frame 203. A guide groove 205 is formed in the middle of the surface of the mounting base 201, and a guide plate 206 is provided at the front end of the inner side of the guide groove 205. The guide plate 206... The end is connected to a connecting plate 207, and a spray head 208 is provided in the middle of one side of the connecting plate 207. The rotating screw 209 is located above the rear side of the mounting base 201, and a reduction motor 210 is installed at the input end of the rotating screw 209. The moving frame 203 is slidably connected to the mounting base 201 through an electric push cylinder 202 and a limit slide rail 204, and the limit slide rail 204 is fixedly connected to the mounting base 201. The guide plate 206 is slidably connected to the guide groove 205 through the moving frame 203, and the guide plate 206 and the connecting plate 207 are rotatably connected to the moving frame 203 through the guide groove 205.

[0036] The spray head 208 is equipped with a liquid supply tank at its input end, allowing for liquid extinguishing in the event of a fire. The sprayed liquid medium is perfluorohexanone + water, which enhances the effect. Continuous intermittent spraying within the container achieves the purpose of cooling and preventing reignition. The electric push cylinder 202 drives the movement of the moving frame 203, allowing the guide plate 206 to slide within the guide groove 205. This enables the connecting plate 207 to adjust the spray head 208 by 180 degrees. The reduction motor 210 drives the rotation of the rotating screw 209, allowing the mounting base 201 to slide. This allows for localized adjustment and spraying to extinguish localized fires when encountering a localized fire source within the container. This prevents unburned areas from being sprayed and becoming damp, ensuring the stable operation of subsequent equipment within the container and avoiding economic losses.

[0037] like Figure 1 , Figure 3 and Figure 4 As shown, the monitoring mechanism 3 for active air intake is located at the front end of the fire extinguishing mechanism 2. The monitoring mechanism 3 includes a fixed cover 301 and a mating groove 303. An air intake fan 302 is provided inside the lower part of the fixed cover 301. The mating groove 303 is opened above one side of the air intake fan 302. A pressing tooth plate 304 is engaged on one side of the mating groove 303. A first turning screw wheel 305 is fixed on the outer side of the pressing tooth plate 304. A smoke sensor 306 is provided inside the upper part of the fixed cover 301. A second turning screw wheel 307 is provided on one side above the smoke sensor 306.

[0038] The smoke sensor 306 can monitor the situation inside the chamber to facilitate subsequent fire extinguishing. The air intake fan 302 can actively draw air from inside the chamber into the smoke sensor 306, thereby accelerating the response and shortening the fire extinguishing time, which helps to prevent the disaster from spreading. The smoke sensor 306 and the air intake fan 302 can be easily and quickly removed by the tight and loose engagement of the first screw wheel 305, the second screw wheel 307, the pressing tooth plate 304, and the mating tooth groove 303, so that they can be easily inspected and replaced during use to ensure the safety inside the chamber.

[0039] like Figure 1 , Figure 5 and Figure 6As shown, a gas replacement mechanism 4 is provided on one side of the inner wall of the main body box 1. The gas replacement mechanism 4 includes an air inlet pipe 401 and a gas guide pipe 403. A solenoid valve 402 is installed in the middle of the air inlet pipe 401. The gas guide pipe 403 is connected to the front end of the air inlet pipe 401. A gas distribution pipe 404 is connected to the front surface of the gas guide pipe 403. An air outlet 405 is installed on one side of the surface of the gas distribution pipe 404. A one-way valve pipe 406 is installed on the top of the main body box 1. The one-way valve pipe 406 is connected to the main body box 1. A composite mechanism 5 for combination connection is provided on the other side of the inner wall of the main body box 1. The composite mechanism 5 includes a heat insulation layer 501 and a flame retardant layer 502. The flame retardant layer 502 is disposed on one side of the surface of the heat insulation layer 501.

[0040] Through the air inlet pipe 401 and the solenoid valve 402, an external air supply tank is installed. In the event of a fire, inert gas can be sprayed into the chamber through the air guide pipe 403 and the air distribution pipe 404, and finally from the air outlet 405. With the exhaust of the one-way valve pipe 406, the air inside the chamber can be replaced, thereby blocking the oxygen required for combustion. Through the cooperation of the heat insulation layer 501 and the flame retardant layer 502, the effectiveness of fire extinguishing and the safety of the chamber can be further improved.

[0041] The technical solution provided by this invention firstly uses a smoke sensor 306 to monitor the situation inside the chamber, which facilitates subsequent fire extinguishing. Then, an air intake fan 302 actively draws air from inside the chamber into the smoke sensor 306 to accelerate the reaction and shorten the fire extinguishing time. Finally, the smoke sensor 306 and the air intake fan 302 can be easily and quickly removed by the tight and loose engagement of the first turning wheel 305, the second turning wheel 307, the pressing toothed plate 304, and the mating toothed groove 303, making it convenient for maintenance and replacement during use.

[0042] At this time, the spray head 208 is equipped with a liquid supply tank at its input end, which can spray liquid to extinguish fire in the event of a fire. The sprayed liquid medium is perfluorohexanone + water cluster to make the effect better. It continuously and intermittently sprays inside the chamber to achieve the purpose of cooling and preventing reignition. Then, the electric push cylinder 202 drives the movement of the moving frame 203, which allows the guide plate 206 to slide in the guide groove 205, thereby allowing the connecting plate 207 to drive the spray head 208 to adjust the angle by 180 degrees. Then, the reduction motor 210 drives the rotation of the rotating screw 209 to make the mounting base 201 slide. When encountering a local fire source inside the chamber, it can make local adjustments to spray and extinguish the fire.

[0043] Then, through the air inlet pipe 401 and the solenoid valve 402, which is equipped with an external air supply tank, in the event of a fire, inert gas can be sprayed into the chamber through the air guide pipe 403 and the air distribution pipe 404 and finally from the air outlet 405. With the exhaust of the one-way valve pipe 406, the air in the chamber can be replaced, thereby blocking the oxygen required for combustion. Finally, the safety of the chamber is ensured through the cooperation of the heat insulation layer 501 and the flame retardant layer 502.

[0044] This invention encompasses any substitutions, modifications, equivalent methods, and solutions made within the spirit and scope of this invention. To provide the public with a thorough understanding of this invention, specific details are described in detail in the following preferred embodiments; however, those skilled in the art will fully understand the invention even without these details. Furthermore, to avoid unnecessary misunderstanding of the essence of this invention, well-known methods, processes, procedures, components, and circuits are not described in detail.
