Description

Technical Field

[0001] This utility model relates to the field of energy storage container technology, and specifically provides an energy storage container. Background Technology

[0002] With the rapid development of the energy storage market, energy storage containers have been widely used. Energy storage containers are equipped with internal fire suppression systems to extinguish fires promptly in the event of battery pack overheating and catching fire, preventing further losses.

[0003] Typically, fire detection and extinguishing devices in a fire protection system are fixed to the top inner wall of an energy storage container with screws. When maintenance or replacement of the fire protection system is required, the battery packs inside the energy storage container must first be removed and taken out before the system can be inspected or replaced from inside the container. This significantly increases the difficulty of maintaining and replacing the fire protection system.

[0004] Therefore, a new technical solution is needed in this field to solve the above problems. Utility Model Content

[0005] The present invention aims to solve the above-mentioned technical problems, namely, the difficulty in inspecting and replacing the fire protection system of existing energy storage containers.

[0006] This utility model provides an energy storage container, which includes a container body and a fire protection system. The top of the container body is provided with an installation port and a mounting plate that can be detachably installed from the outside of the container body to the installation port. The fire protection system includes a fire detection device and a fire extinguishing device, and both the fire detection device and the fire extinguishing device are located inside the mounting plate.

[0007] In the preferred embodiment of the above-mentioned energy storage container, the mounting port is located in the middle area of ​​the top of the container.

[0008] In the preferred technical solution of the above-mentioned energy storage container, liquid coolers are installed in the top two sides of the container body.

[0009] In the preferred technical solution of the above-mentioned energy storage container, the mounting plate is fixedly connected to the portion of the container body located at the edge of the mounting opening by bolts.

[0010] In the preferred embodiment of the above-mentioned energy storage container, a threaded hole is formed on the portion of the container body located at the edge of the mounting opening, and a first through hole corresponding to the threaded hole is formed on the mounting plate. The stud of the bolt passes through the first through hole and is threadedly engaged with the threaded hole; or the bolt is equipped with a nut, and the bolt is fixed on the portion of the container body located at the edge of the mounting opening with its head facing upward. A second through hole corresponding to the bolt is formed on the mounting plate, and the stud of the bolt passes through the second through hole and is threadedly engaged with the nut.

[0011] In the preferred technical solution of the above-mentioned energy storage container, the fire detection device includes a temperature detector, a combustible gas detector and / or a smoke detector; and / or the fire extinguishing device includes a water nozzle and / or an aerosol fire extinguishing device.

[0012] In the preferred technical solution of the above-mentioned energy storage container, the fire protection system further includes an intake fan and an exhaust fan, which are installed on the door of the energy storage container and are electrically connected to the fire detection device via cables.

[0013] In the preferred technical solution of the above-mentioned energy storage container, the cable is connected to the air intake fan and the exhaust fan via quick-connect couplings.

[0014] In the preferred technical solution of the above-mentioned energy storage container, a burst relief plate is also provided in the middle area of ​​the top of the container.

[0015] In the preferred technical solution of the above-mentioned energy storage container, the explosion relief plate is arranged adjacent to the installation port; or the explosion relief plate is arranged on the installation plate.

[0016] When the above technical solution is adopted, the energy storage container includes a container body and a fire protection system. The top of the container body is provided with an installation port and a mounting plate that can be detachably installed from the outside of the container body to the installation port. The fire protection system includes a fire detection device and a fire extinguishing device, and both the fire detection device and the fire extinguishing device are located inside the mounting plate.

[0017] With this setup, when the fire protection system of the energy storage container needs to be inspected and replaced, simply remove the mounting plate at the top mounting opening of the energy storage container from the outside. The fire detection device and fire extinguishing device located on the inside of the mounting plate will then be removed from the energy storage container along with the mounting plate. This facilitates the inspection and replacement of the fire detection device and fire extinguishing device of the fire protection system, reduces the difficulty of inspecting and replacing the fire protection system of the energy storage container, and makes the inspection and replacement of the fire protection system of the energy storage container more convenient.

[0018] Preferably, the mounting port is located in the middle area of ​​the top of the housing.

[0019] With this setup, the fire detection and extinguishing devices of the fire protection system are concentrated in the middle area of ​​the top of the energy storage container, reducing the space occupied by the fire protection system. The space on both sides of the top of the energy storage container can be used to install other components, thereby improving the space utilization rate inside the energy storage container.

[0020] Preferably, liquid coolers are installed in the top two sides of the housing.

[0021] This setup, compared to placing the liquid cooler on the outside of one side of the energy storage container, not only improves the space utilization inside the energy storage container but also reduces its footprint.

[0022] Preferably, the mounting plate is fixedly connected to the portion of the housing located at the edge of the mounting opening by bolts.

[0023] Because the fire detection and extinguishing devices of the fire protection system in existing energy storage containers are fixed to the top inner wall of the energy storage container with screws, iron filings and cable sheaths are generated during the process of fixing the fire detection and extinguishing devices to the top inner wall of the energy storage container with screws. These debris fall onto the battery pack, high voltage box and liquid cooling pipeline. The iron filings and cable sheaths that fall onto the battery pack, high voltage box and liquid cooling pipeline are not only difficult to clean, but also affect electrical safety.

[0024] By fixing the mounting plate to the edge of the mounting opening of the container with bolts, it is possible to prevent iron filings, cable sheaths, and other debris from falling onto the battery pack, high-voltage box, and liquid cooling pipeline during the installation of fire detection and extinguishing devices of the fire protection system. This ensures the cleanliness of the interior of the energy storage container and improves the electrical safety performance of the energy storage container.

[0025] Preferably, the fire protection system also includes an intake fan and an exhaust fan, which are installed on the door of the energy storage container and are electrically connected to the fire detection device via cables.

[0026] This design not only allows for heat dissipation of the battery packs and electrical components inside the energy storage container, reducing the risk of overheating and fire, but also enables the timely removal of flammable gases when they are generated, further reducing the risk of fire, and assists in fire suppression systems in the event of a fire. The intake and exhaust fans are located on the doors of the energy storage container, facilitating their installation, maintenance, and replacement.

[0027] Preferably, the cables connecting the intake fan and exhaust fan to the fire detection device are connected to the intake fan and exhaust fan via quick-connect couplings.

[0028] This setup allows for easy disassembly and assembly of the intake and exhaust fans.

[0029] Preferably, a venting plate is also provided in the middle area of ​​the top of the enclosure.

[0030] This design not only prevents a serious explosion of the energy storage container in the event of a fire inside, but also avoids excessive use of the container's internal space, thus reducing its space utilization rate. Attached Figure Description

[0041] First, those skilled in the art should understand that the embodiments described below are merely for explaining the technical principles of this utility model and are not intended to limit the scope of protection of this utility model.

[0042] It should be noted that in the description of this utility model, terms such as "upper," "lower," "left," "right," "front," and "rear," indicating directional or positional relationships, are based on the directional or positional relationships shown in the accompanying drawings. These are merely for ease of description and do not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0043] Furthermore, it should be noted that in the description of this utility model, unless otherwise explicitly specified and limited, the term "connection" should be interpreted broadly. For example, it can refer to a fixed connection, a detachable connection, or an integral connection; it can be a direct connection or an indirect connection. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0044] In view of the problem mentioned in the background art that the fire protection system of existing energy storage containers is difficult to inspect and replace, this utility model provides an energy storage container. The energy storage container includes a container body and a fire protection system. The top of the container body is provided with an installation port and a mounting plate that can be detachably installed from the outside of the container body to the installation port. The fire protection system includes a fire detection device and a fire extinguishing device, and both the fire detection device and the fire extinguishing device are located inside the mounting plate.

[0045] With this setup, when the fire protection system of the energy storage container needs to be inspected and replaced, simply remove the mounting plate at the top mounting opening of the energy storage container from the outside. The fire detection device and fire extinguishing device located on the inside of the mounting plate will then be removed from the energy storage container along with the mounting plate. This facilitates the inspection and replacement of the fire detection device and fire extinguishing device of the fire protection system, reduces the difficulty of inspecting and replacing the fire protection system of the energy storage container, and makes the inspection and replacement of the fire protection system of the energy storage container more convenient.

[0046] The following reference Figures 1 to 7 This invention provides a detailed description of the energy storage container of this utility model. Among other things, Figure 1 This is a schematic diagram of the structure of an energy storage container according to an embodiment of the present invention; Figure 2 This is a top view of an energy storage container according to an embodiment of the present invention (the mounting plate is hidden); Figure 3 yes Figure 2 A magnified view of part A in the middle; Figure 4This is a front view of an energy storage container according to an embodiment of the present invention (the front side of the container is hidden); Figure 5 yes Figure 4 A magnified view of part B in the middle; Figure 6 yes Figure 5 A magnified view of part C in the middle; Figure 7 This is a right view of an energy storage container according to an embodiment of the present invention.

[0047] like Figure 1 , Figure 2 and Figure 4 As shown, the energy storage container includes a container body 1, inside which multiple battery packs 2 are stacked. The top of the container body 1 has a mounting opening 11 and a mounting plate 3 that is detachably installed from the outside of the container body 1 onto the mounting opening 11. The mounting opening 11 is located in the middle area of ​​the top of the container body 1. The energy storage container includes a fire protection system, which includes a fire detection device and a fire extinguishing device, both of which are located inside the mounting plate 3. Figure 3 and Figure 5 As shown, the fire detection device includes a heat detector 31, a combustible gas detector 32, and a smoke detector 33. The fire extinguishing device includes a water nozzle 34 and an aerosol fire extinguishing device 35. The water nozzle 34 is connected to the tap water pipe at the location of the energy storage container via a pipeline. Figure 1 and Figure 2 As shown, a venting plate 4 is also provided in the middle area of ​​the top of the housing 1, and the venting plate 4 is arranged adjacent to the mounting port 11.

[0048] like Figure 3 and Figure 6 As shown, an annular sealing strip 36 is sandwiched between the mounting plate 3 and the portion of the housing 1 located at the edge of the mounting opening 11. Multiple bolts 37 are distributed around the mounting opening 11 on the portion of the housing 1 located at the edge of the mounting opening 11. Each bolt 37 is equipped with a nut 38. The bolts 37 are welded and fixed to the portion of the housing 1 located at the edge of the mounting opening 11 with their heads facing upwards. Through holes 361 are distributed on the sealing strip 36 at positions corresponding to the bolts 37. Through holes are also distributed on the mounting plate 3 at positions corresponding to the bolts 37 (not shown in the figure). The sealing strip 36 is attached to the lower side of the mounting plate 3, and the through holes 361 on the sealing strip 36 are aligned with the through holes on the mounting plate 3. The through holes 361 on the sealing strip 36 and the through holes on the mounting plate 3 are fitted onto the bolts 37. The nuts 38 are threadedly engaged with the studs of the bolts 37 and press against the upper surface of the mounting plate 3, thereby fixing the mounting plate 3 at the mounting opening 11.

[0049] like Figure 4 As shown, a liquid cooler 5 is installed on each of the two sides of the top of the casing 1. The liquid cooler 5 is used to cool the battery pack 2 inside the casing 1. Figure 1 and Figure 2As shown, heat dissipation vents 51 are respectively provided on the top of the container 1 and directly opposite the liquid chiller 5, which are used to dissipate the heat of the liquid chiller 5 into the air outside the energy storage container.

[0050] like Figure 1 and Figure 7 As shown, a first door 12 is provided on the left side of the enclosure 1, and a second door 13 is provided on the right side of the enclosure 1. The fire protection system also includes an intake fan 121 and an exhaust fan 131. The intake fan 121 is located on the first door 12 of the enclosure 1, and the exhaust fan 131 is located on the second door 13 of the enclosure 1. The intake fan 121 and the exhaust fan 131 are electrically connected to a temperature detector 31, a combustible gas detector 32, and a smoke detector 33 via cables.

[0051] During daily use, the temperature detector 31 monitors the temperature inside the container 1 in real time, the combustible gas detector 32 monitors whether combustible gas is generated inside the container 1 in real time, and the smoke detector 33 monitors whether smoke is generated inside the container 1 in real time. The intake fan 121, exhaust fan 131, water sprinkler head 34, and aerosol fire extinguishing device 35 perform corresponding actions based on the detection results of the temperature detector 31, combustible gas detector 32, and smoke detector 33. In the event of a fire, if the gas pressure inside the container 1 suddenly increases and reaches a preset value, the explosion relief plate 4 is ruptured by the gas, thereby quickly reducing the pressure inside the container 1 and preventing the container 1 from bursting and damaging nearby energy storage containers.

[0052] When it is necessary to inspect and replace the temperature detector 31, combustible gas detector 32, smoke detector 33, water sprinkler head 34, and aerosol fire extinguishing device 35, simply remove the mounting plate 3 at the mounting port 11 from the outside. The temperature detector 31, combustible gas detector 32, smoke detector 33, water sprinkler head 34, and aerosol fire extinguishing device 35, which are located on the inside of the mounting plate 3, can then be removed from the container 1 along with the mounting plate 3. This facilitates the inspection and replacement of the temperature detector 31, combustible gas detector 32, smoke detector 33, water sprinkler head 34, and aerosol fire extinguishing device 35 without having to remove the battery pack 2 inside the container 1. When it is necessary to inspect and replace the air intake fan 121 and the exhaust fan 131, simply open the first door 12 and the second door 13. This reduces the difficulty of inspecting and replacing the fire protection system of the energy storage container and makes the inspection and replacement of the fire protection system of the energy storage container more convenient.

[0053] The mounting port 11 is located in the middle area of ​​the top of the container 1, which concentrates the fire detection device and fire extinguishing device of the fire protection system in the middle area of ​​the top of the energy storage container, reducing the space occupied by the fire protection system. The space on both sides of the top of the energy storage container can be used to install other components, thereby improving the space utilization rate inside the energy storage container.

[0054] Liquid coolers 5 are installed on both sides of the top of the container 1. Compared with the method of "the liquid cooler is installed on the outside of one side of the energy storage container", this not only improves the space utilization rate inside the energy storage container, but also reduces the footprint of the energy storage container.

[0055] Because existing fire detection and extinguishing devices in energy storage containers are fixed to the inner top wall of the container with screws, iron filings and cable sheathing are generated during the installation process and fall onto the battery pack, high-voltage box, and liquid cooling pipes. This debris is difficult to clean and can compromise electrical safety. The mounting plate 3 of this invention is bolted to the edge of the mounting opening 11 of the container body. This prevents iron filings and cable sheathing from falling onto the battery pack, high-voltage box, and liquid cooling pipes during installation, thus ensuring the cleanliness of the energy storage container's interior and improving its electrical safety performance.

[0056] It should be noted that the liquid chiller 5 is installed on both sides of the top inside the container 1. This is only a preferred arrangement and can be adjusted in practical applications. For example, the liquid chiller can also be installed on the outside of one side of the container 1, and the battery pack can be installed on both sides of the top inside the container 1 to improve the energy density of the energy storage container. Additionally, the mounting port 11 is located in the middle of the top of the container 1. This is also a preferred arrangement and can be adjusted in practical applications. For example, the mounting port 11 can be located near the edge of the top of the container 1, or it can be located over the entire top area of ​​the container 1. Furthermore, the explosion relief plate 4 is arranged adjacent to the mounting port 11. This is only one specific arrangement and can be adjusted in practical applications. For example, in one feasible arrangement, the explosion relief plate is mounted on the mounting plate 3, which also facilitates the installation and replacement of the explosion relief plate.

[0057] It should also be noted that the fire detection device includes a heat detector 31, a combustible gas detector 32, and a smoke detector 33, and the fire extinguishing device includes a water nozzle 34 and an aerosol fire extinguishing device 35. This is only a preferred configuration, and it can be adjusted in actual applications. For example, the fire detection device may include only one or two of the heat detector 31, combustible gas detector 32, and smoke detector 33, and / or the fire extinguishing device may include only one of the water nozzle 34 and the aerosol fire extinguishing device 35.

[0058] In another feasible embodiment, unlike the above embodiment, a threaded hole is formed on the part of the housing 1 located at the edge of the mounting opening 11, and a through hole corresponding to the threaded hole is formed on the mounting plate 3. The stud of the bolt passes through the through hole of the mounting plate 3 and the through hole 361 of the sealing strip 36 in sequence from top to bottom and is threadedly engaged with the threaded hole, thereby fixing the mounting plate 3 at the mounting opening 11.

[0059] In another feasible embodiment, unlike the above embodiment, the portion of the housing 1 located at the edge of the mounting opening 11 is detachably connected to the mounting plate 3 through the engagement of claws and locking holes.

[0060] Based on the above embodiments, preferably, the cables connecting the intake fan 121 and the exhaust fan 131 to the fire detection device are connected to the intake fan 121 and the exhaust fan 131 via quick-connect couplings. This arrangement allows for easier assembly and disassembly of the intake fan 121 and the exhaust fan 131.

[0061] The technical solution of this utility model has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the protection scope of this utility model is obviously not limited to these specific embodiments. Without departing from the principle of this utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of this utility model.
