Description

Technical Field

[0001] This utility model belongs to the technical field of energy storage power stations, and particularly relates to a fire extinguishing device for battery modules in energy storage power stations. Background Technology

[0002] An energy storage power station is a large-scale facility that uses multiple battery packs to store electrical energy and release it when needed. Because a power station operates with a large number of batteries, and each battery has different properties, operating environments, and is susceptible to heat dissipation system malfunctions and external factors, it is difficult to avoid individual batteries experiencing thermal runaway and catching fire. When a battery catches fire due to thermal runaway, it is difficult to extinguish due to the battery's chemical reaction characteristics, limitations of fire extinguishing materials, and structural design limitations. The burning battery can then ignite surrounding batteries and other components, causing further damage and increasing the fire's intensity. Utility Model Content

[0003] The purpose of this invention is to provide a fire extinguishing device for battery modules in an energy storage power station, which can prevent the burning battery from igniting other batteries and components around it when a battery in the energy storage power station catches fire unexpectedly, thereby avoiding the spread of damage and the increase of the fire.

[0004] A fire extinguishing device for battery modules in an energy storage power station includes several energy storage cabinets installed on the energy storage power station. There is a fire extinguishing space between two adjacent energy storage cabinets. The energy storage cabinets are equipped with automatic doors that can open and close automatically. An installation rack is installed inside the energy storage cabinet. The installation rack has several placement positions. A conveyor belt and a temperature probe are installed in each placement position. One end of the conveyor belt is located next to the automatic door. Batteries are placed on the conveyor belt. Fire extinguishing nozzles are installed outside the energy storage cabinets next to the automatic door.

[0005] When the temperature probe detects that the battery is too hot, the conveyor belt will send the battery out of the automatic door to the outside of the energy storage cabinet and drop it into the fire extinguishing space. After that, the automatic door will isolate the battery from the inside of the energy storage cabinet, and the fire extinguishing nozzles will cool down the battery and extinguish the fire.

[0006] According to the technical solution, the present invention achieves the following beneficial effects:

[0007] When a battery operating inside the energy storage cabinet experiences thermal runaway and catches fire, a conveyor belt transports the battery out of the cabinet via an automatic door and drops it outside. At this point, the thermally runaway battery falls into the fire extinguishing space. Subsequently, the automatic door closes to isolate the thermally runaway battery in the fire extinguishing space from the other batteries and components inside the energy storage cabinet. Simultaneously, fire extinguishing nozzles cool and extinguish the thermally runaway battery in the fire extinguishing space, thereby preventing the thermally runaway battery from igniting the normal batteries and other components inside the energy storage cabinet, thus avoiding further damage and increasing the fire's intensity.

[0008] To further optimize the above technical solutions, they can be combined with one or more of the following implementation methods without conflict.

[0009] In some embodiments, a socket electrically connected to a power controller is installed at the other end of the conveyor belt, and the battery is equipped with a plug for electrically connecting to the socket.

[0010] Based on the aforementioned technical solution, the following beneficial effects can be further achieved:

[0011] 1. When installing the battery in the storage cabinet, the battery is fed in by a conveyor belt. At this time, the battery plug is connected to the socket, so that the battery can be easily connected to the power controller.

[0012] 2. When the conveyor belt delivers the thermally runaway battery, the battery plug is pulled out of the socket, allowing the battery to be easily disconnected from the power controller.

[0013] In some embodiments, a fixing cylinder is installed at the top of the placement position, and the fixing cylinder is connected to a fixing rod so that when the battery plug is connected to the socket, the fixing cylinder drives the fixing rod to fix the battery.

[0014] Based on the aforementioned technical solution, when the conveyor belt feeds the battery and the battery plug is inserted into the socket, the fixed cylinder drives the fixed rod to fix the battery, thereby ensuring that the plug is stably inserted into the socket.

[0015] In some implementations, the energy storage cabinet and automatic doors are equipped with heat-insulating and fire-resistant layers to prevent thermal runaway batteries from transferring heat to the batteries and components inside the energy storage cabinet.

[0016] In some embodiments, the conveyor belt is mounted on a slant frame, one end of which is located next to the automatic door and connected to the placement bearing, and the other end of the slant frame is connected to a lifting electric cylinder.

[0017] Based on the aforementioned technical solution, during the process of the conveyor belt sending the battery out of the automatic door to the outside of the energy storage cabinet and dropping it, the lifting cylinder drives the other end of the inclined adjustment frame to rise, causing the inclined adjustment frame to tilt the conveyor belt, thereby enabling the conveyor belt to send the battery out more stably and efficiently.

[0018] In some implementations, each energy storage cabinet is signal-connected to another adjacent energy storage cabinet so that when the high-temperature battery inside the energy storage cabinet is pushed into the fire extinguishing space, the other adjacent energy storage cabinet closes its automatic door and controls the fire extinguishing nozzles to assist in extinguishing the fire.

[0019] Based on the aforementioned technical solution, the present invention further achieves the following beneficial effects:

[0020] Once the thermal runaway battery inside the energy storage cabinet is removed, the cabinet can send a signal to nearby cabinets to close their automatic doors. This prevents the thermally runaway battery from igniting the normal batteries and other components in the surrounding cabinets. Furthermore, after the surrounding cabinets close their automatic doors, they can also control the fire sprinklers to cool and extinguish the thermal runaway battery, thereby further improving fire suppression efficiency.

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the following description is provided with reference to the accompanying drawings. Example

[0029] like Figures 2 to 4 As shown, this embodiment provides a fire extinguishing device for battery modules of an energy storage power station, which includes several energy storage cabinets 2 installed on an energy storage power station 1, and a fire extinguishing space 11 between two adjacent energy storage cabinets 2.

[0030] The energy storage cabinet 2 is equipped with an automatic door 21 that can open and close automatically. The automatic door 21 can be designed with reference to the conventional structure of automatic swing doors and automatic sliding doors on the market. Both the energy storage cabinet 2 and the automatic door 21 are equipped with heat insulation and fireproof layers.

[0031] The energy storage cabinet 2 is equipped with a mounting rack 3, which has several placement positions 31. Each placement position 31 contains a tilting bracket 41, a socket 33, a fixing cylinder 34, and a temperature probe 32. One end of the tilting bracket 41 is located next to the automatic door 21 and is connected to the placement position 31 by a bearing 43. The other end of the tilting bracket 41 is connected to the lifting cylinder 42. A conveyor belt 4 is mounted on the tilting bracket 41. One end of the conveyor belt 4 is located next to the automatic door 21, and the socket 33 is located next to the other end of the conveyor belt 4. The plug 51 is electrically connected to the power controller 23 inside the energy storage cabinet 2. The conveyor belt 4 is used to place batteries 5, and each battery 5 is equipped with a plug 51 for electrical connection to the socket 33. The temperature probe 32 is used to monitor the temperature of the batteries 5 on the conveyor belt 4. The temperature probe 32 can determine whether the battery 5 has thermal runaway if it senses that the temperature of the battery 5 is higher than a set stable temperature, indicating a fire risk.

[0032] The energy storage cabinet 2 is equipped with a fire extinguishing nozzle 22 located next to the automatic door 21. The fire extinguishing nozzle 22 can refer to the principle and structure of the intelligent fire water cannon. The fire extinguishing nozzle 22 is connected to the water supply device.

[0033] The following is a description of the operation of a fire extinguishing device for battery modules in an energy storage power station as described in this embodiment.

[0034] When the battery 5 is working normally inside the energy storage cabinet 2, the automatic door 21 can be in the open state to facilitate heat dissipation of the battery 5.

[0035] When installing the battery 5 in the energy storage cabinet 2, the battery 5 can be fed in using the conveyor belt 4, and limit strips can be set on both sides of the conveyor belt 4 to allow the battery 5 to move linearly; then, the plug 51 of the battery 5 is connected to the socket 33, so that the battery 5 can be easily connected to the power controller 23; then, the fixed cylinder 34 drives the fixed rod 35 to fix the battery 5, and the fixed rod 35 can fix the battery 5 by pressing down, blocking displacement, etc.

[0036] When the battery 5 is installed in the energy storage cabinet 2, the fixed cylinder drives the fixing rod 35 to reset and move away from the battery 5; then, the conveyor belt 4 sends the battery 5 out of the energy storage cabinet, at which time the plug 51 of the battery 5 is also pulled out of the socket 33.

[0037] When the battery 5 operating inside the energy storage cabinet 2 experiences thermal runaway and catches fire, the fixed cylinder drives the fixing rod 35 to reset and move the battery 5 away. Subsequently, the conveyor belt 4 sends the battery 5 out of the automatic door 21 to the outside of the energy storage cabinet 2 and it falls outside. When the plug 51 on the battery 5 is also pulled out of the socket 33, the lifting cylinder 42 drives the other end of the tilting frame 41 to rise, causing the tilting frame 41 to drive the end of the conveyor belt 4 near the automatic door 21 to tilt downwards until the thermally runaway battery 5 falls into the fire extinguishing space 11. After that, the automatic door 21 closes to isolate the thermally runaway battery 5 in the fire extinguishing space 11 from the other batteries 5 and components in the energy storage cabinet 2. The fire extinguishing nozzle 22 cools and extinguishes the thermally runaway battery 5 in the fire extinguishing space 11. Example

[0038] like Figures 2 to 4 As shown, this embodiment provides a fire extinguishing device for battery modules of an energy storage power station, which includes several energy storage cabinets 2 installed on an energy storage power station 1, and a fire extinguishing space 11 between two adjacent energy storage cabinets 2.

[0039] The energy storage cabinet 2 is equipped with an automatic door 21 that can open and close automatically. The automatic door 21 can be designed with reference to the conventional structure of automatic swing doors and automatic sliding doors on the market. Both the energy storage cabinet 2 and the automatic door 21 are equipped with heat insulation and fireproof layers.

[0040] The energy storage cabinet 2 is equipped with a mounting frame 3, which has several placement positions 31. Each placement position 31 contains a tilting frame 41, a fixing cylinder 34, and a temperature probe 32. One end of the tilting frame 41 is located next to the automatic door 21 and is connected to the placement position 31 by a bearing 43. The other end of the tilting frame 41 is connected to the lifting cylinder 42. A conveyor belt 4 is mounted on the tilting frame 41, with one end located next to the automatic door 21. The conveyor belt 4 is used to hold batteries 5, which are electrically connected to a power controller 23 via cables. The temperature probe 32 is used to monitor the temperature of the batteries 5 on the conveyor belt 4.

[0041] The energy storage cabinet 2 is equipped with a fire extinguishing nozzle 22 located next to the automatic door 21. The fire extinguishing nozzle 22 can refer to the principle and structure of the intelligent fire water cannon. The fire extinguishing nozzle 22 is connected to the water supply device.

[0042] The following is a description of the operation of a fire extinguishing device for battery modules in an energy storage power station as described in this embodiment.

[0043] When the battery 5 is working normally inside the energy storage cabinet 2, the automatic door 21 can be in the open state to facilitate heat dissipation of the battery 5.

[0044] When installing battery 5 into energy storage cabinet 2, battery 5 is electrically connected to power controller 23 via cable. Then, battery 5 can be fed into the cabinet using conveyor belt 4. When battery 5 is installed into energy storage cabinet 2, the fixed rod 35 is reset and moved away from battery 5 by the constant-electrode cylinder; then, conveyor belt 4 sends battery 5 out of the energy storage cabinet; then, the cable on battery 5 is disconnected from power controller 23.

[0045] When the battery 5 operating inside the energy storage cabinet 2 experiences thermal runaway and catches fire, the lifting cylinder 42 drives the other end of the tilting frame 41 to rise, causing the tilting frame 41 to tilt the end of the conveyor belt 4 near the automatic door 21 downwards. Simultaneously, the conveyor belt 4 transports the battery 5 from the automatic door 21 to the outside of the energy storage cabinet 2, where it falls. At this point, the thermally runaway battery 5 will fall into the fire extinguishing space 11. Afterwards, the automatic door 21 closes to isolate the thermally runaway battery 5 in the fire extinguishing space 11 from the other batteries 5 and components in the energy storage cabinet 2. The fire extinguishing nozzle 22 cools and extinguishes the thermally runaway battery 5 in the fire extinguishing space 11. The cable connecting the battery 5 to the power controller 23 can be broken when the battery 5 falls into the fire extinguishing space 11, or the automatic door 21 can directly clamp the cable when closing. Example

[0046] like Figure 1 As shown, the embodiment provides a fire extinguishing device for battery modules of an energy storage power station, which includes all the features of embodiment 1 or 2, and also includes the following feature: each energy storage cabinet 2 is signal connected to another adjacent energy storage cabinet.

[0047] After the thermal runaway battery 5 in the energy storage cabinet 2 is delivered, the energy storage cabinet 2 sends a signal to the surrounding energy storage cabinets 2 to close the automatic door 21, thereby preventing the thermal runaway battery 5 from igniting the normal batteries 5 and other components in the surrounding energy storage cabinets 2. In addition, after closing the automatic door 21, the surrounding energy storage cabinets 2 can also control the fire extinguishing nozzles 22 to cool down and extinguish the thermal runaway battery 5.
