Description

Technical Field

[0001] This invention relates to the field of energy storage technology, and more specifically, to an energy storage container fire extinguishing system. Background Technology

[0002] When a battery pack inside an energy storage container catches fire or explodes, firefighting is required.

[0003] In existing technologies, fire extinguishing methods all involve directly eliminating the fire source inside the battery pack. Common solutions include perfluorohexanone and aerosol fire extinguishing. However, if the fire source inside the battery pack cannot be extinguished, the battery pack will continue to burn, causing other battery packs inside the container to continue burning, resulting in other property damage. Even if the fire source is extinguished, there will still be a lot of residual hazardous substances affecting other battery packs inside the container. Summary of the Invention

[0004] This invention provides a fire extinguishing system for energy storage containers, which can extinguish fires in battery packs without affecting other battery packs, thus reducing property damage.

[0005] The embodiments of the present invention can be implemented as follows:

[0006] This invention provides an energy storage container fire extinguishing system, comprising:

[0007] An energy storage container, comprising a container body, a battery pack, and a sliding mechanism, wherein the sliding mechanism is disposed in the container body, the battery pack is disposed in the container body, and the sliding mechanism is used to drive the battery pack to slide out of the container body and fall along the sliding path upon receiving a control signal;

[0008] A fire extinguishing ditch is located next to the enclosure, and the fire extinguishing ditch is located in the sliding path of the battery pack, so that the battery pack can fall into the fire extinguishing ditch along the sliding path.

[0009] In an optional implementation, the control signal is a fire signal.

[0010] In an optional embodiment, the fire extinguishing trench is provided with a flipping mechanism that can switch between a first state where the fire extinguishing trench is covered and a second state where the fire extinguishing trench is open.

[0011] In an optional implementation, the battery pack that slides out of the housing can act on the flipping mechanism to switch it from the first state to the second state.

[0012] In an optional embodiment, the flipping mechanism includes a flap that can rotate relative to the fire extinguishing trench. The flap includes a first plate and a second plate arranged at an angle. When the battery pack falls into the fire extinguishing trench, it causes the first plate to flip, thereby driving the second plate to switch from a second state of opening the fire extinguishing trench to a first state of covering the fire extinguishing trench.

[0013] In an optional embodiment, the flap further includes a third plate, which is connected to the second plate at an angle; when the battery pack falls into the fire extinguishing trench, it causes the first plate to flip, thereby causing the third plate to protrude from one side of the fire extinguishing trench.

[0014] In an optional embodiment, both the first plate and the third plate are perpendicularly connected to the second plate, and the first plate and the third plate are located in the same plane.

[0015] In an optional embodiment, the flipping mechanism includes a rotating rod, and the first plate, the second plate, and the third plate are all connected to the rotating rod, which is rotatably mounted on the fire extinguishing trench.

[0016] In an optional embodiment, the inner wall of the fire extinguishing trench is lined with a cement layer, and the inner wall of the cement layer is lined with a waterproof coating.

[0017] In an optional implementation, the number of fire extinguishing trenches is multiple.

[0018] In an optional embodiment, the fire extinguishing trench is a ring-shaped trench that surrounds the energy storage container.

[0019] The beneficial effects of the energy storage container fire suppression system according to embodiments of the present invention include, for example:

[0020] This invention provides a fire suppression system for an energy storage container. The system includes an energy storage container and a fire suppression ditch located beside the container. The energy storage container includes a container body, a battery pack, and a sliding mechanism. The sliding mechanism is disposed within the container body, and the battery pack is disposed within the container body. Upon receiving a control signal, the sliding mechanism causes the battery pack to slide out of the container body and fall along a sliding path. The fire suppression ditch is located within the sliding path of the battery pack, allowing the battery pack to fall into the ditch. In the event of a fire in the battery pack within the container, the sliding mechanism receives a control signal and slides the burning battery pack out of the container and into the fire suppression ditch along the sliding path, reducing the impact on other battery packs and minimizing property damage. Simultaneously, the fire suppression ditch can extinguish the fire in the burning battery pack. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0032] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0033] It should be noted that, where there is no conflict, the features in the embodiments of the present invention can be combined with each other.

[0034] With the development of new energy technologies, power storage technology has developed rapidly, and energy storage containers are gradually being widely used.

[0035] As mentioned in the background section, firefighting is required when the battery pack inside the energy storage container catches fire and explodes.

[0036] In existing technologies, fire extinguishing methods all involve directly eliminating the fire source inside the battery pack. Common solutions include perfluorohexanone and aerosol fire extinguishing, as well as liquid immersion fire extinguishing. However, if the fire source inside the battery pack cannot be extinguished, the battery pack will continue to burn, causing other battery packs inside the container to continue burning, resulting in other property damage. Even if the fire source is extinguished, there will still be a lot of residual hazardous substances affecting other battery packs inside the container.

[0037] In view of this, please refer to Figures 1-5 The energy storage container fire extinguishing system provided in the embodiments of the present invention can solve this problem, and will be described in detail below.

[0038] Please refer to Figure 1 and Figure 2This invention provides an energy storage container fire extinguishing system, which includes an energy storage container 100 and a fire extinguishing ditch 200 located next to the container body 110. The energy storage container 100 includes the container body 110, a battery pack 120, and a sliding mechanism (not shown). The sliding mechanism is disposed in the container body 110, and the battery pack 120 is disposed in the container body 110. The sliding mechanism is used to drive the battery pack 120 to slide out of the container body 110 and fall along the sliding path when a control signal is received. The fire extinguishing ditch 200 is disposed in the sliding path of the battery pack 120, and the battery pack 120 can fall into the fire extinguishing ditch 200 along the sliding path.

[0039] The control signal can be understood as a fire signal. In the event of a fire in some of the battery packs 120 in the housing 110, the sliding mechanism can receive the control signal and slide the burning battery pack 120 out of the housing 110 and into the fire extinguishing trench 200 along the sliding path, reducing the impact on other battery packs and reducing property damage. At the same time, the fire extinguishing trench 200 can extinguish the fire in the burning battery pack 120.

[0040] Because the burning battery pack 120 can be slid out of the housing 110, it prevents the battery pack 120 from continuing to burn and causing the other battery packs inside the housing to continue to burn. At the same time, it also prevents residual hazardous substances from affecting the other battery packs inside the housing.

[0041] Specifically, the fire extinguishing trench 200 is used to contain the fire extinguishing liquid 20. It should be noted that the fire extinguishing liquid 20 can be saline solution.

[0042] It should be noted that in this embodiment, the container 110 of the energy storage container 100 is installed on the ground 10, and the fire extinguishing trench 200 is a trench dug on the ground 10. The inner wall of the fire extinguishing trench 200 is lined with a cement layer 201, which can prevent the gravel on the side wall of the dug fire extinguishing trench 200 from collapsing. At the same time, the inner wall of the cement layer 201 is lined with a waterproof coating 202 to prevent the loss of fire extinguishing liquid 20.

[0043] Of course, in other embodiments, the fire extinguishing trench 200 may also be a structure with a receiving groove assembled from profiles, the receiving groove being used to hold the fire extinguishing liquid 20.

[0044] It should be noted that, in order to ensure that the battery pack 120 in the housing 110 falls into the fire extinguishing ditch 200 as much as possible when it slides out, there are multiple fire extinguishing ditches 200. Here, "multiple" can be understood as at least two, such as two fire extinguishing ditches 200, three fire extinguishing ditches 200, or four fire extinguishing ditches 200, etc.

[0045] In this embodiment, there are two fire extinguishing trenches 200, which are distributed on opposite sides of the housing 110 and spaced apart from the housing 110.

[0046] When the battery pack 120 inside the enclosure 110 catches fire and explodes, the enclosure door 111 on the enclosure 110 opens, and the battery pack 120 slides out from the enclosure door 111 and falls into the corresponding fire extinguishing ditch 200, thereby extinguishing the fire of the battery pack 120.

[0047] In this embodiment, the sliding mechanism may include multiple inclined support plates and multiple fire sensors, with each inclined support plate carrying a battery pack 120.

[0048] It is easy to understand that in order to detach the battery pack 120 that has caught fire from the housing 110 as accurately as possible, multiple fire sensors can be installed in the housing 110, with each battery pack 120 corresponding to one fire sensor, and the fire sensor can detect whether the corresponding battery pack 120 has caught fire.

[0049] When one or more battery packs 120 catch fire, the corresponding fire sensor receives the fire signal and can control the door 111 of the enclosure 110 adjacent to these battery packs 120 to open. At the same time, these battery packs 120 slide out under the influence of gravity and fall into the fire extinguishing trench 200. It is easy to understand that the battery packs 120 can be slidably mounted on the inclined support plate in the enclosure 110 so that the battery packs 120 can slide out under the influence of gravity.

[0050] Of course, in some embodiments, the sliding mechanism also includes a lifting device, which can increase the tilt angle of the inclined support plate so that the battery pack 120 can slide out of the housing 110 under the action of gravity.

[0051] Of course, in some embodiments, the sliding mechanism can be a conveying mechanism with a conveyor belt. The battery pack 120 is set on the conveyor belt. When one or more battery packs 120 catch fire, the conveying mechanism can receive the fire signal through the fire sensor and then drive the conveyor belt to move, so that the battery pack 120 is driven by the conveyor belt until it slides out of the box 110 and falls into the fire extinguishing trench 200.

[0052] Of course, please refer to this. Figure 3 In other embodiments, the fire extinguishing trench 200 may also be an annular trench, surrounding the energy storage container 100.

[0053] Please refer to Figure 4 It should be noted that, in the event that the battery pack 120 is not on fire, in order to prevent dust or other soil and rocks in the air from falling into the fire extinguishing trench 200, the fire extinguishing trench 200 is equipped with a flipping mechanism 300, which can switch between a first state of covering the fire extinguishing trench 200 and a second state of opening the fire extinguishing trench 200.

[0054] Specifically, the battery pack 120 that slides out of the housing 110 can act on the flipping mechanism 300 to switch it from the first state to the second state.

[0055] The flipping mechanism 300 includes a flap that can rotate relative to the fire extinguishing trench. The flap includes a first plate 310 and a second plate 320 connected at an angle. Both the first plate 310 and the second plate 320 can be rotatably installed in the fire extinguishing trench 200.

[0056] When the first plate 310 and the second plate 320 are not flipped, the first plate 310 can cover the fire extinguishing trench 200, while the second plate 320 protrudes from the edge of the fire extinguishing trench 200 to prevent animals or other personnel from walking into the fire extinguishing trench 200 and improve safety.

[0057] However, when the battery pack 120 falls into the fire extinguishing trench 200, the battery pack 120 can cause the first plate 310 to flip, thereby driving the second plate 320 to switch from the second state of opening the fire extinguishing trench to the first state of covering the fire extinguishing trench 200.

[0058] Please refer to the following: Figure 5 In the event of a fire, the battery pack 120 slides out of the housing 110 and falls onto the first plate 310. Generally, the battery pack 120 weighs more than 300 kilograms. Under the influence of gravity, the battery pack 120 can cause both the first plate 310 and the second plate 320 to rotate. The first plate 310 flips over into the fire extinguishing trench 200 and no longer covers the fire extinguishing trench 200. At the same time, the battery pack 120 can fall from the first plate 310 into the fire extinguishing trench 200. Meanwhile, the second plate 320 continues to cover the fire extinguishing trench 200, preventing the burning battery pack 120 from burning other items.

[0059] In addition, the flap also includes a third plate 330, which is connected to the second plate 320 at an angle. When the burning battery pack 120 does not fall onto the first plate 310, the third plate 330 is laid flat on the edge of the fire extinguishing trench 200.

[0060] When the battery pack 120 falls into the fire extinguishing ditch 200, the battery pack 120 causes the first plate 310 to flip, which in turn causes the third plate 330 to protrude on one side of the fire extinguishing ditch 200. At this time, the second plate 320 covers the fire extinguishing ditch 200 to continue to prevent animals or other people from walking into the fire extinguishing ditch 200 and improve safety.

[0061] In this embodiment, the first plate 310 and the third plate 330 are both vertically connected to the second plate 320. The first plate 310 and the third plate 330 are located in the same plane. That is, when the burning battery pack 120 does not fall onto the first plate 310, the first plate 310 is laid flat above the fire extinguishing trench 200, covering the fire extinguishing trench 200. The third plate 330 is laid flat on the edge of the fire extinguishing trench 200 away from the box 110. The second plate 320 is perpendicular to the ground 10 and protrudes from the edge of the fire extinguishing trench 200.

[0062] In this embodiment, the first plate 310, the second plate 320 and the third plate 330 are all covered with ceramic fiber material, which can be used to block the flame of combustion.

[0063] In the event of a fire, if the battery pack 120 slides out of the housing 110 and falls onto the first plate 310, the first plate 310, the second plate 320, and the third plate 330 will all rotate, specifically, by a rotation angle of ninety degrees.

[0064] The first plate 310 flips over into the fire extinguishing trench 200, and the burning battery pack 120 falls into the fire extinguishing trench 200 and is extinguished by salt water. The second plate 320 covers the top of the fire extinguishing trench 200 again. At the same time, the third plate 330 protrudes from one side of the fire extinguishing trench 200 to continue to prevent animals or other personnel from walking into the fire extinguishing trench 200.

[0065] Meanwhile, the flipping mechanism 300 includes a rotating rod 340, which is a circular steel pipe. The first plate 310, the second plate 320, and the third plate 330 are all connected to the rotating rod 340. Two bearings are provided on the edge of the fire extinguishing trench 200, and the bearings are sleeved on both ends of the rotating rod 340. The rotating rod 340 is rotatably installed in the fire extinguishing trench 200.

[0066] To facilitate maintenance of the energy storage container 100, a small bridge (not shown) can be erected above the fire extinguishing ditch 200. The small bridge allows maintenance personnel to cross the fire extinguishing ditch 200 and enter the energy storage container 100 for maintenance.

[0067] For the fire extinguishing trench 200 with annular groove, small bridges can be erected on both sides of the box 110 along its length, allowing maintenance personnel to access the doors on both sides of the box 110 for maintenance.

[0068] According to the energy storage container fire extinguishing system provided in this embodiment, the working principle of the energy storage container fire extinguishing system is as follows:

[0069] Please refer to Figure 4Before the burning battery pack 120 falls onto the first plate 310, the first plate 310 is laid flat above the fire extinguishing trench 200, covering the fire extinguishing trench 200. The third plate 330 is laid flat on the edge of the fire extinguishing trench 200 away from the box 110. The second plate 320 is perpendicular to the ground 10 and protrudes from the edge of the fire extinguishing trench 200.

[0070] Please refer to Figure 5 When one or more battery packs 120 in the housing 110 catch fire, the corresponding fire sensor can control the door 111 of the housing 110 adjacent to these battery packs 120 to open. At the same time, these battery packs 120 slide out under the action of gravity and fall onto the first plate 310 above the fire extinguishing trench 200. The first plate 310, the second plate 320 and the third plate 330 all rotate.

[0071] The first plate 310 flips over into the fire extinguishing trench 200, and the burning battery pack 120 falls into the fire extinguishing trench 200 and is extinguished by salt water. The second plate 320 covers the top of the fire extinguishing trench 200 again. At the same time, the third plate 330 protrudes from one side of the fire extinguishing trench 200 to continue to prevent animals or other personnel from walking into the fire extinguishing trench 200. The energy storage container fire extinguishing system prevents the heat from the burning battery pack 120 from spreading and causing problems to other battery packs 120, reducing the impact on other battery packs 120 and reducing property damage.

[0072] After the battery pack 120 enters the fire extinguishing trench 200, firefighters and other safety personnel wait around until the battery cells inside the battery pack 120 have reacted with the salt water before handling the battery pack 120 to prevent the flames from burning the staff.

[0073] In summary, the energy storage container fire suppression system includes an energy storage container 100 and a fire suppression ditch 200 located next to the container body 110. The energy storage container 100 includes the container body 110, a battery pack 120, and a sliding mechanism. The sliding mechanism is located within the container body 110, and the battery pack 120 is located within the container body 110. Upon receiving a control signal, the sliding mechanism causes the battery pack 120 to slide out of the container body and fall along a sliding path. The fire suppression ditch is located within the sliding path of the battery pack 120, allowing the battery pack 120 to fall into the fire suppression ditch 200. In the event of a fire in the battery pack within the container body 110, the sliding mechanism receives a control signal and slides the burning battery pack 120 out of the container body 110 and into the fire suppression ditch 200 along the sliding path, reducing the impact on other battery packs and minimizing property damage. Simultaneously, the fire suppression ditch 200 can extinguish the fire in the burning battery pack.

[0074] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
