Description

Technical Field

[0001] This utility model relates to the field of fire protection equipment technology, and in particular to a fire exhaust device and an energy storage container. Background Technology

[0002] With the rapid development of the new energy industry, the large-scale application of energy storage systems (such as lithium battery energy storage boxes) has placed higher demands on thermal safety management. When a battery overheats abnormally or catches fire, high-temperature gases, flammable fumes, and toxic substances will rapidly accumulate inside the box. If these cannot be expelled in time, they can easily cause a secondary explosion or accelerate the spread of thermal runaway.

[0003] Existing container ventilation systems use fixed exhaust vents, with their locations and connections to the fans fixed. However, battery ignition points are random, and fixed vents cannot dynamically target the fire source area, resulting in low ventilation efficiency, prolonged retention of high-temperature gases, and an inability to effectively suppress the spread of fire.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A fire exhaust device includes an energy storage component, a guide component, and an exhaust component. The energy storage component has an internal receiving space and an exhaust port communicating with the receiving space.

[0008] In one embodiment, along the length of the first guide rail, the first guide rail includes a first end and a second end disposed opposite to each other. The first end is close to the exhaust port, and the second end is away from the exhaust port. A plurality of second guide rails are disposed sequentially at intervals on the first guide rail and located between the first end and the second end.

[0011] In one embodiment, the fire exhaust device includes a connecting component, one end of which is slidably connected to the guide component, and the other end of which is connected to the exhaust component.

[0012] In one embodiment, the connecting component includes a sliding member and a rotating member. The sliding member and the guide member are slidably connected, the rotating member and the sliding member are rotatably connected, and the rotating member and the exhaust member are connected.

[0014] In one embodiment, the exhaust component includes a fire extinguishing pipe connected to the guide component, and the fire extinguishing pipe has multiple fire extinguishing ports for spraying fire extinguishing materials.

[0015] To achieve the above objectives, the present invention also adopts the following technical solution: an energy storage container, including a fire exhaust device and a battery pack according to any of the above embodiments, wherein the battery pack is disposed in the accommodating space, and the exhaust component is used to absorb the smoke generated by the thermal runaway of the battery pack.

[0016] The beneficial effects of this utility model are as follows: This application provides a fire exhaust device and an energy storage container.

[0029] The terms “center,” “longitudinal,” “lateral,” “length,” “width,” “thickness,” “upper,” “lower,” “front,” “rear,” “left,” “right,” “vertical,” “horizontal,” “top,” “bottom,” “inner,” “outer,” “radial,” and “circumferential” indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0031] See Figure 1 This application provides an energy storage container, including a fire exhaust device and a battery pack. The fire exhaust device includes an energy storage component 1 and an exhaust component 3. The energy storage component 1 has an internal accommodating space 12 and an exhaust vent 11 communicating with the accommodating space 12. The battery pack is located in the accommodating space 12 of the energy storage component 1, and the exhaust component 3 is used to absorb the smoke generated by the thermal runaway of the battery pack.

[0032] In practical applications, the exhaust component 3 is connected to the exhaust vent 11, which effectively discharges the smoke generated by the thermal runaway of the battery pack to the outside of the energy storage component 1, thereby ensuring the safety of the internal environment. The fire exhaust system is typically equipped with a power component 5, which drives the exhaust component 3 to ensure that the smoke can be quickly discharged. The power component 5 can be implemented using a structure such as a fan.

[0033] See Figure 2The fire exhaust device also includes a guide component 2, which is connected to the energy storage component 1. The guide component 2 extends at least partially along the length of the energy storage component 1. One end of the exhaust component 3 is connected to the exhaust port 11, and the other end is slidably connected to the guide component 2 and connected to the accommodating space 12.

[0034] In practical applications, the energy storage component 1 can be implemented using a box or cabinet structure, with its internal space used for battery pack installation and smoke collection. The guide component 2 is responsible for guiding the movement trajectory of the exhaust component 3. Its structure can be a guide rail or a slide, and its extension direction covers the length direction of the energy storage component 1 to expand the position adjustment range of the exhaust component 3. As a movable pipe connecting the fire source area and the exhaust vent 11, the exhaust component 3 can flexibly change its position through a sliding connection to achieve precise alignment with different areas.

[0035] When thermal runaway of the battery pack occurs inside the energy storage component 1, smoke accumulates within the containment space 12. The arrangement of the guide component 2, extending along the length of the energy storage component 1, provides a reference for the movement of the exhaust component 3. The exhaust component 3 moves along the guide component 2 to the fire source area via a sliding connection, directly connecting this area to the exhaust port 11. Smoke generated by the fire source is quickly guided by the exhaust component 3 to the exhaust port 11 for discharge, forming a directional exhaust path. When the position of the fire source changes, the exhaust component 3 can slide along the guide component 2 to a new position, maintaining the dynamic alignment of the exhaust path.

[0036] It should be noted that the sliding connection between the exhaust component 3 and the guide component 2 can be a magnetic connection. An external control system energizes the guide component 2, creating a changing magnetic field and generating an electromagnetic force. Driven by this electromagnetic force, the exhaust component 3 can move along the guide component 2. The length of the exhaust component 3 can be selected according to the actual dimensions of the energy storage component 1, so that the exhaust component 3 can reach various positions within the energy storage component 1. In one embodiment, the exhaust component 3 can also be a bellows or other structure with its own telescopic function. Alternatively, this application may also include a linear drive motor connected to the exhaust component 3, driving the exhaust component 3 to move on the guide component 2.

[0037] Compared with existing technologies, the exhaust component 3 with sliding connection realizes the position adjustment of the exhaust path to cope with the randomness of the fire source position. Through the cooperation of the guide component 2 and the sliding structure, the range of action of the exhaust port 11 is extended to the entire length of the energy storage component 1, which solves the problem of reduced exhaust efficiency caused by fire source positioning deviation.

[0038] See Figure 3The guide component 2 includes a first guide rail 21 and a second guide rail 22 connected to each other. The first guide rail 21 extends along the length direction of the energy storage component 1 and is located at the top of the energy storage component 1. The second guide rail 22 extends along the width direction of the energy storage component 1. The exhaust component 3 can be selectively slid to the first guide rail 21 or the second guide rail 22.

[0039] To describe clearly, Figure 3 In the middle, the X direction represents the length direction of energy storage component 1, the Y direction represents the width direction of energy storage component 1, and the Z direction represents the height direction of energy storage component 1.

[0040] In practical applications, the first guide rail 21 can be a track structure extending along the length of the energy storage container, used to guide the exhaust component 3 to move horizontally within the length of the container. The second guide rail 22 can be a track structure extending along the width of the energy storage component 1, allowing the exhaust component 3 to obtain displacement freedom along the width of the container. The intersecting layout of the first guide rail 21 and the second guide rail 22 forms a movement path in a planar coordinate system. The exhaust component 3 dynamically covers the ignition points in different areas of the top of the container through a combination of longitudinal and lateral sliding. The first guide rail 21 can be set on the top of the energy storage component 1. Based on the physical characteristic that high-temperature smoke tends to rise, the first guide rail 21 at the top facilitates the exhaust component 3's absorption of smoke from various locations.

[0041] See again Figure 3 Along the length of the first guide rail 21, the first guide rail 21 includes a first end 211 and a second end 212 that are disposed opposite to each other. The first end 211 is close to the exhaust port 11, and the second end 212 is away from the exhaust port 11. A plurality of second guide rails 22 are disposed sequentially at intervals on the first guide rail 21 and are located between the first end 211 and the second end 212.

[0042] In practical applications, the first end 211 refers to the starting position of the first guide rail 21 near the exhaust port 11, usually the end point directly aligned with the exhaust port 11, which facilitates shortening the initial movement path of the exhaust component 3; the second end 212 refers to the ending position of the first guide rail 21 away from the exhaust port 11; multiple second guide rails 22 refer to transverse branch guide rails spaced apart along the length of the first guide rail 21, which can be implemented using a strip track structure perpendicular to the first guide rail 21, forming multiple path switching nodes along the width direction of the energy storage component 1. Furthermore, multiple second guide rails 22 are located between the first end 211 and the second end 212, rather than being set at either the first end 211 or the second end 212. This arrangement shortens the movement path of the exhaust component 3, thereby shortening the length of the exhaust component 3 and saving material costs.

[0043] The exhaust component 3 can move flexibly along the length of the first guide rail 21 and autonomously select to enter the adjacent second guide rail 22 according to the specific location of the fire source. By setting multiple transverse branch guide rails between the first end 211 and the second end 212 of the first guide rail 21, for example, when the fire source appears in the middle area of ​​the top of the energy storage component 1, the exhaust component 3 can slide directly from the first guide rail 21 to the second guide rail 22 near the fire source, and then move along the second guide rail 22 to the target position. This guide rail layout makes the movement path of the exhaust component 3 form a grid distribution, which not only retains the main path of movement in the length direction, but also realizes rapid local position adjustment through the branch paths in the width direction.

[0044] It should be noted that both the first guide rail 21 and the second guide rail 22 can be electromagnetic guide rails. By controlling the current of the first guide rail 21 and the second guide rail 22, electromagnetic force is generated to realize the movement of the exhaust component 3.

[0045] In one embodiment, the first guide rail 21 and the second guide rail 22 can adopt the structure of mechanical rails, such as linear guide rails, and the first guide rail 21 and the second guide rail 22 can be slidably connected. The exhaust component 3 is slidably connected to the first guide rail 21. The first guide rail 21 can slide along the length direction of the second guide rail 22, that is, slide along the width direction of the energy storage component 1, thereby driving the exhaust component 3 to slide along the width direction. This arrangement can also realize the movement of the exhaust component 3 in both longitudinal and transverse directions.

[0046] Specifically, see Figure 4 There can be two second guide rails 22, which are slidably connected to the first end 211 and the second end 212 of the first guide rail 21, respectively. The two second guide rails 22 are located at both ends of the length direction of the first guide rail 21. On the one hand, they can support the first guide rail 21, and on the other hand, they can allow the first guide rail 21 to slide along the width direction, so as to realize the multi-directional movement of the exhaust component 3.

[0047] See Figure 5 The fire exhaust device includes a connecting component 4, one end of which is slidably connected to the guide component 2, and the other end is connected to the exhaust component 3.

[0048] In practical applications, the guide component 2 can adopt an electromagnetic track structure, and the connecting component 4 can adopt a magnetic component. By utilizing the sliding cooperation between the magnetic component and the electromagnetic track, the exhaust component 3 can move directionally along the guide component 2. Once thermal runaway is detected at a certain point in the energy storage component 1, the control system will instruct the connecting component 4 to move precisely to the preset position along the guide component 2, thereby driving the exhaust component 3 to move to the designated position and achieving the effect of directional exhaust.

[0049] It should be noted that the connecting component 4 can integrate monitoring components, such as infrared, smoke, or temperature sensors. The monitoring components are electrically connected to the external control system. When the monitoring components detect thermal runaway at a certain point, they transmit a signal to the external control system. The control system generates an electromagnetic force by energizing the guide component 2. Under the push of the electromagnetic force, the connecting component 4 drives the guide component 2 to move to the designated position.

[0050] See again Figure 5 The connecting component 4 includes a sliding component 41 and a rotating component 42. The sliding component 41 is slidably connected to the guide component 2, the rotating component 42 is rotatably connected to the sliding component 41, and the rotating component 42 is connected to the exhaust component 3.

[0051] In practical applications, the sliding member 41 controls the spatial position of the exhaust member 3 by displacing along the guide member 2, allowing the exhaust member 3 to be moved to any ignition point on the energy storage member 1. Once the sliding member 41 is in position, the rotating member 42 drives the exhaust member 3 to rotate around its axis, adjusting the smoke angle of the exhaust member 3 and achieving directional control in three-dimensional space. This combined sliding and rotating motion enables the exhaust member 3 to quickly reach different areas while precisely aligning with the core area of ​​the fire source, forming a dynamic smoke extraction path that tracks the fire point.

[0052] See Figure 6 The exhaust component 3 includes an exhaust pipe 31, one end of which is slidably connected to the guide component 2, and the other end is connected to the exhaust port 11. The exhaust pipe 31 includes an outer pipe 311, an inner pipe 312, and a heat insulation part 313. The outer pipe 311 is sleeved on the outer periphery of the inner pipe 312, and the gap between the outer pipe 311 and the inner pipe 312 forms the heat insulation part 313, which is used for heat insulation.

[0053] In practical applications, the outer tube 311 can be a tubular structure fitted over the outside of the exhaust pipe 31, used to insulate against external heat radiation and protect the structural integrity of the inner tube 312. The inner tube 312 can be a tubular structure inside the exhaust pipe 31, used to directly guide high-temperature smoke and reduce heat transfer outwards. The heat insulation part 313 can be the space between the outer tube 311 and the inner tube 312, specifically implemented by using an air layer or filling with aerogel material, blocking heat diffusion from the inner tube 312 to the outer tube 311 by reducing heat conduction efficiency.

[0054] The exhaust pipe 31 is connected to the guide component 2 via a sliding connection, allowing it to dynamically adjust the smoke exhaust direction according to the location of the fire source. In the high-temperature flue gas duct system, the inner pipe 312 is in direct contact with the high-temperature flue gas, while the heat is effectively blocked by the heat insulation part 313. Due to the excellent performance of the heat insulation material, the outer pipe 311 is prevented from deforming or cracking due to thermal expansion. For example, when the heat insulation part 313 is an air layer, the airflow can carry away some of the heat, thereby reducing the heat transferred from the inner pipe 312 to the outer pipe 311. The outer pipe 311, as a protective layer, can block the radiant heat generated by the external fire from affecting the inner pipe 312, thereby maintaining the overall structural stability of the exhaust pipe 31 and ensuring unobstructed smoke exhaust path.

[0055] See Figure 7 The exhaust component 3 includes a fire pipe 32, which is connected to the guide component 2. The fire pipe 32 has multiple fire extinguishing ports 321 for spraying fire extinguishing materials.

[0056] In practical applications, the fire extinguishing pipe 32 can be a pipeline structure for conveying fire extinguishing materials. The fire extinguishing pipe 32 is connected to the guide component 2 and extends along the extension direction of the guide component 2. The fire extinguishing pipe 32 has multiple fire extinguishing ports 321 along its extension direction. The multi-directional extension rail of the guide component 2 allows the fire extinguishing pipe 32 to be arranged in the length, width, or height direction, so that the fire extinguishing ports 321 can be aimed at the actual fire source location. The multiple fire extinguishing ports 321 form a multi-point spray structure on the surface of the fire extinguishing pipe 32. The fire extinguishing material diffuses into the fire source area through the fire extinguishing ports 321 at different locations, so that the spray range of the fire extinguishing material can cover the area around the ignition point, eliminating the spray blind zone caused by the randomness of the fire source location.

[0057] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0058] Furthermore, in addition to indicating direction or positional relationship, some of the aforementioned terms may also have other meanings. For example, the term "above" may also be used in some cases to indicate a certain dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this utility model according to the specific circumstances.

[0059] The above description is only a specific embodiment of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
