Detailed Implementation

[0023] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0024] The following is in conjunction with the appendix Figure 1 - Appendix Figure 7 The energy storage cabinet of the present invention will be described in detail.

[0025] The energy storage cabinet of this embodiment includes a cabinet body 1, a cabinet door 2, a placement plate 3, a slide 4, a support 5, and an insulating layer 6. The cabinet door 2 is rotatably connected to the cabinet body 1. The placement plate 3 is detachably disposed inside the cabinet body 1. There are multiple placement plates 3, which are spaced apart inside the cabinet body 1. The placement plate 3 is provided with a fire sprinkler head 7 and is used to place battery modules. The upper end surface of the placement plate 3 is provided with sliding grooves on both sides in a first direction. The sliding grooves extend along a second direction, which is orthogonal to the first direction. The two ends of the sliding grooves are slidably engaged with slides 4. The first end of the support 5 is connected to one of the two slides 4 arranged opposite to each other in the first direction. The second end of the support 5 is connected to the other slide 4 arranged opposite to each other in the first direction. There are two U-shaped supports 5, which are arranged opposite to each other in the second direction. The supports 5 can rotate around the first direction relative to the slides 4. The insulating layer 6 is flexible and is disposed between the support 5 and the placement plate 3 so that the insulating layer 6 moves when the support 5 moves.

[0026] In this embodiment of the energy storage cabinet, a sliding seat 4 is provided in the sliding groove on the upper end face of the placement plate 3. The sliding seat 4 drives the support 5 to move so that the isolation layer 6 between the support 5 and the placement plate 3 can cover the top of the placement plate 3, thereby isolating the placement plate 3 from other placement plates 3 in the energy storage cabinet. The fire extinguishing agent is sprayed by the fire sprinkler 7 on the placement plate 3 to extinguish the fire on the placement plate 3, preventing the fire on the battery module of the placement plate 3 from affecting the battery modules on other placement plates 3. At the same time, it can also prevent the fire extinguishing agent from spraying onto other battery modules, ensuring the normal use of other battery modules and improving the safety of the energy storage cabinet.

[0027] Specifically, such as Figures 1-5 As shown, the cabinet door 2 is hinged to the cabinet body 1. Multiple placement plates 3 for installing battery modules are detachably connected inside the cabinet body 1. The upper surface of the placement plate 3 has sliding grooves on both sides in the first direction, and the sliding grooves are slidably connected to the sliding seats 4 at both ends in the second direction.

[0028] The placement plate 3 has inverted U-shaped supports 5 at both ends in the second direction. Each end of a support 5 is connected to a corresponding slide 4. That is, the two ends of the support 5 are arranged opposite each other in the first direction. One end of the support 5 is connected to a slide 4 in one groove in the first direction, and the other end of the support 5 is connected to a slide 4 in another groove in the first direction. Since there are two grooves, each groove contains two slides 4, meaning there are four slides 4 and two supports 5. The two ends of one support 5 are connected to two of the slides 4, and the two ends of the other support 5 are connected to the other two slides 4, allowing the two supports 5 to move closer to or further apart in the second direction. The angle between the support 5 and the slide 4 is adjustable, and a flexible insulating layer 6 is provided between the support 5 and the ends of the placement plate 3.

[0029] The placement plate 3 is equipped with fire sprinklers 7 for spraying extinguishing agents. When the two supports 5 on the placement plate 3 are close to each other to isolate the placement plate 3 from the outside world, the fire sprinklers 7 spray the extinguishing agents onto the placement plate 3 to extinguish the fire.

[0030] It is understood that the slide 4 is connected to a drive unit (not shown) for driving the slide 4 to move in the slide groove along the second direction. For example, the drive unit is a motor, which realizes the movement of the slide 4 in the slide groove.

[0031] When the battery module on the placement plate 3 is charging and discharging normally, the bracket 5 remains horizontal, and the insulating layer 6 is located between the bracket 5 and the placement plate 3. After the battery module on the placement plate 3 catches fire, the drive slide 4 slides towards each other to move the bracket 5 until the slide 4 touches each other. During the sliding process of the slide 4, the bracket 5 rotates from a horizontal state to a vertical state. When the slide 4 touches each other, the two brackets 5 on the same placement plate 3 abut against each other, so that the insulating layer 6 completely covers the battery module. At this time, fire extinguishing operation is carried out by controlling the fire sprinkler head 7 to spray fire extinguishing agent. The insulating layer 6 and the placement plate 3 isolate the burning battery module from the outside world and prevent air from contacting the fire source. This can assist in fire extinguishing and also prevent the fire extinguishing agent from spraying onto other battery modules, thus avoiding affecting the normal operation of other battery modules.

[0032] In some embodiments, the energy storage cabinet further includes ear plates 8 and a rotating shaft 9. There are two ear plates 8, which are symmetrically arranged on the slide 4. The rotating shaft 9 is rotatably inserted between the two ear plates 8. The bracket 5 is connected to the rotating shaft 9. The slide 4 is provided with a receiving groove 11 that is parallel to and connected to the slide groove. A toothed plate 12 is provided in the receiving groove 11. One end of the rotating shaft 9 passes through the ear plate 8 and is connected to the drive gear 10. The drive gear 10 meshes with the toothed plate 12.

[0033] Specifically, such as Figures 2-3 As shown, ear plates 8 are symmetrically arranged on the slide block 4. A rotating shaft 9, which is horizontal and perpendicular to the slide groove, is rotatably connected between the ear plates 8. The end of the bracket 5 is fixedly connected to the rotating shaft 9. A drive gear 10 is provided at the end of the rotating shaft 9. A receiving groove 11 parallel to the slide groove is opened on both sides. A toothed plate 12 that meshes with the drive gear 10 is provided at the lower side wall end of the receiving groove 11.

[0034] When the battery module on the placement plate 3 is charging and discharging normally, the drive gear 10 meshes with the toothed plate 12. When the battery module on the placement plate 3 catches fire, the drive component drives the slide block 4 to move towards each other. At this time, because the drive gear 10 meshes with the toothed plate 12, the drive gear 10 can drive the rotating shaft 9 to rotate synchronously, thereby driving the bracket 5 to rotate until the bracket 5 is rotated from a horizontal state to a vertical state. Then the drive gear 10 separates from the toothed plate 12, realizing the rotation of the bracket 5.

[0035] In some embodiments, the rotating shaft 9 is provided with a plurality of guide grooves arranged at intervals along its circumference, a limit rod 13 is slidably fitted in the guide groove, an elastic reset member 14 is provided between the limit rod 13 and the guide groove, and a plurality of limit holes 15 are provided on the inner wall of the ear plate 8 to cooperate with the limit rod 13, and the longitudinal section of the limit hole 15 is arc-shaped.

[0036] Specifically, such as Figure 3 and Figure 7 As shown, multiple guide grooves facing the axis of the shaft 9 are provided on both sides of the shaft 9. Limiting rods 13 are slidably connected in the guide grooves, and elastic reset members 14 are provided between the limiting rods 13 and the guide grooves. Several limiting holes 15 that cooperate with the limiting rods 13 are provided on the inner wall of the ear plate 8. The longitudinal section of the limiting holes 15 is arc-shaped.

[0037] In this embodiment, during the rotation of the shaft 9, the shaft 9 can drive the limiting rod 13 to deflect synchronously. Utilizing the arc-shaped surface of the limiting hole 15, the limiting rod 13 disengages from the limiting hole 15, allowing the shaft 9 to continue rotating. When the drive gear 10 disengages from the gear plate 12, the limiting rod 13, under the action of the elastic reset member 14, inserts into the corresponding limiting hole 15, thereby restricting the shaft 9 from continuing to deflect and thus fixing the position of the bracket 5, preventing the bracket 5 from deflecting and affecting the insulation and sealing performance of the insulating layer 6 on the battery module.

[0038] In some embodiments, the placement plate 3 is provided with mounting grooves on both sides in the second direction, the mounting grooves are connected to the sliding grooves, and the mounting grooves are used to accommodate the bracket 5 and the insulating layer 6.

[0039] Specifically, such as Figures 2-5 As shown, the upper surface of the placement plate 3 has mounting grooves on both sides in the second direction for accommodating the bracket 5 and the insulating layer 6, and the two ends of the mounting grooves are connected to the adjacent sliding grooves. By setting the mounting grooves, the bracket 5 is prevented from protruding from the placement plate 3, which would affect the normal assembly and disassembly of the battery module. Moreover, the bracket 5 and the insulating layer 6 are neatly stored, resulting in a high level of aesthetics.

[0040] In some embodiments, the energy storage cabinet further includes a water-cooled pipe 16 and a connecting pipe. The water-cooled pipe 16 is disposed inside the placement plate 3. One end of the water-cooled pipe 16 is adapted to communicate with the pump, and the other end of the water-cooled pipe 16 is connected to the connecting pipe. The connecting pipe passes through the receiving groove 11 and extends into the insulation layer 6.

[0041] Specifically, such as Figures 4-6As shown, each placement plate 3 is equipped with a water-cooling pipe 16 inside. A pump (not shown) is installed inside the placement plate 3 to pump coolant into the water-cooling pipe 16. A connecting pipe extending into the receiving groove 11 is connected to the water-cooling pipe 16, with the other end of the connecting pipe extending into the insulation layer 6. By installing the water-cooling pipe 16 inside the placement plate 3, the placement plate 3 and the battery module installed on it can be cooled, improving the heat dissipation efficiency of the battery module and reducing the probability of the battery module catching fire.

[0042] In some embodiments, the insulating layer 6 is double-layered with a cavity formed between the two layers, one end of the connecting pipe extends into the cavity, and the connecting pipe is provided with a solenoid valve 18 for controlling the on / off state.

[0043] Specifically, such as Figures 4-6 As shown, the interior of the insulating layer 6 is hollow, and the connecting pipe 17 is connected to the interior of the adjacent end of the insulating layer 6. A solenoid valve 18 is installed on the connecting pipe 17.

[0044] In this embodiment of the energy storage cabinet, when a battery module on the placement plate 3 catches fire, the movement of the bracket 5 causes the insulating layer 6 to cover the battery module, while simultaneously opening the solenoid valve 18 and the fire sprinkler head 7. This allows the coolant in the water-cooling pipe 16 to flow into the insulating layer 6, causing it to expand. This further brings the insulating layer 6 closer to the battery module, further reducing the fire space and allowing the extinguishing agent to tightly cover the battery module and isolate it from air, thus accelerating the fire extinguishing process. Furthermore, after the insulating layer 6 expands, it fills the mounting groove and sliding groove, enhancing its insulating effect. In addition, the coolant continuously cools the battery module through the insulating layer 6, accelerating fire extinguishing while preventing reignition. The coolant also protects the insulating layer 6, preventing the battery module from igniting it.

[0045] In some embodiments, the energy storage cabinet further includes a return pipe 20, which connects the chamber to the pump, and a solenoid valve 18 is provided on the return pipe 20 to control its on / off state.

[0046] Specifically, such as Figures 4-6 As shown, the return pipe 20 is connected to the chamber and the pump, which can return the coolant in the chamber to the pump, thus realizing the loop between the water cooling pipe 16, the insulation layer 6 and the pump, thereby achieving continuous cooling of the battery module.

[0047] In some embodiments, the energy storage cabinet further includes a sensing component and a controller. The sensing component includes a temperature sensor, a smoke sensor, and a pressure sensor. The controller is connected to the sensing component, the fire sprinkler head 7, the solenoid valve 18, and a drive for controlling the sliding of the slide block 4.

[0048] Specifically, the placement plate 3 is equipped with a sensing component for detecting battery modules. By incorporating temperature and smoke sensors, the detection accuracy for battery module fire detection is improved, preventing false alarms. Furthermore, when the sensing component detects a fire, the controller only opens the solenoid valve 18 on the connecting pipe 17, while the solenoid valve 18 on the return pipe 20 remains closed. During the expansion of the insulation layer 6, the pressure sensor is compressed by the insulation layer 6. When the pressure sensor detects pressure exceeding the safe range, the controller opens the solenoid valve 18 on the return pipe 20, creating a loop between the water-cooling pipe 16, the insulation layer 6, and the pump, thereby continuously cooling the battery module. Moreover, the sensing component and controller enable automated monitoring and automated fire suppression.

[0049] After the sensing component detects a fire in the battery module installed on the placement plate 3, it can control the drive component to move the slide 4, thereby causing the two supports 5 to move closer to each other. Moreover, the controller is connected to the solenoid valve 18 on the connecting pipe 17 and the solenoid valve 18 on the return pipe 20, which can control the opening and closing of the connecting pipe 17 and the return pipe 20, resulting in a higher degree of automation.

[0050] In some embodiments, the cabinet door 2 is provided with an alarm 19 connected to the controller.

[0051] Specifically, such as Figure 1 As shown, an alarm 19 connected to the controller is installed on cabinet door 2. By setting the alarm 19, staff can be quickly notified to take further action and prevent the fire from spreading further.

[0052] In some embodiments, the two brackets 5 can be brought closer to each other and engaged by the slide 4, and the two brackets 5 are provided with a rubber layer on the side facing each other.

[0053] Specifically, such as Figures 2-4 As shown, when the two supports 5 approach each other in the second direction until they abut against each other, the two supports 5 engage with each other, and the end face of the supports 5 is provided with a rubber layer, which can enhance the sealing between the supports 5 and prevent the air in the isolation layer 6 from leaking out through the gap between the two supports 5.

[0054] For example, magnets can also be installed on the two supports 5, so that when the two supports 5 are against each other, the two supports 5 are tightly attached together by magnetic force.
