DETAILED DESCRIPTION

[0024] Embodiments of the present application are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below by reference to the drawings are exemplary and are intended to explain the present application, and cannot be understood as limiting the present application.

[0025] A fireproof control box for energy storage equipment according to an embodiment of the present application is described below in conjunction with the drawings.

[0026] As shown in Figures 1 to 5 , the fireproof control box for energy storage equipment according to an embodiment of the present application comprises a cabinet body, an energy storage assembly 3, a plugging assembly and a fire extinguishing assembly. The cabinet body comprises a lower cabinet body 1 and an upper cabinet body 2, and the lower cabinet body 1 is detachably connected to the upper cabinet body 2. The peripheral wall of the upper cabinet body 2 is provided with ventilation holes 4, the energy storage assembly 3 is arranged in the lower cabinet body 1, and the plugging assembly is arranged in the upper cabinet body 2.

[0027] The blocking assembly has a first state and a second state. When the blocking assembly is in the first state, the blocking assembly separates the inner cavity of the upper cabinet 2 into a first chamber and a second chamber, the first chamber is located above the second chamber, the ventilation hole 4 is communicated with the second chamber, and the fire extinguishing assembly is arranged in the first chamber. When the blocking assembly is in the second state, the blocking assembly stops separating the inner cavity of the upper cabinet 2, and the blocking assembly blocks the ventilation hole 4, and the fire extinguishing assembly is used for extinguishing the energy storage assembly 3.

[0028] In the related art, the ventilation hole of the cabinet body introduces oxygen during a fire, which causes the fire to intensify. In the embodiment of the present application, the ventilation hole can be quickly blocked in the second state of the blocking assembly, and oxygen is isolated, thereby effectively inhibiting the spread and expansion of the fire. This design can cut off the oxygen supply in the early stage of the fire, gain valuable time for the intervention of the fire extinguishing assembly, and reduce the loss caused by the fire.

[0029] The first state of the blocking assembly separates the inner cavity of the upper cabinet 2 into a first chamber and a second chamber, and the ventilation hole 4 is communicated with the second chamber, which guarantees the heat dissipation requirement of the energy storage assembly 3 during normal operation. When the fire occurs, the blocking assembly switches to the second state, and the separation of the chambers is removed and the ventilation hole 4 is blocked, so that the fire extinguishing assembly can act on the area where the energy storage assembly 3 is located, thereby improving the fire extinguishing efficiency.

[0030] By dynamically blocking the ventilation hole, the problem of out-of-control fire caused by the introduction of oxygen through the ventilation hole in the related art is avoided, and the safety of the energy storage equipment is significantly improved. The intervention of the fire extinguishing assembly further enhances the fire response capability of the system, which can quickly respond in the early stage of the fire and prevent the fire from expanding.

[0031] Therefore, the fire control box for the energy storage equipment in the embodiment of the present application constructs a complete fire prevention and control system through the cooperative work of the blocking assembly and the fire extinguishing assembly, and significantly improves the reliability of the energy storage equipment. The switching mechanism of the system in the normal operation and the fire response state ensures that the system can operate efficiently and safely in different working conditions.

[0032] In a normal state, the blocking assembly is in the first state, the energy storage assembly 3 dissipates heat through the ventilation hole 4, and the working effect of the energy storage assembly 3 is guaranteed. When the fire occurs inside the cabinet, the blocking assembly is in the second state, the blocking assembly blocks the ventilation hole 4 to avoid the entry of oxygen, and at the same time, the fire extinguishing assembly is used to extinguish the energy storage assembly 3 to prevent the expansion and spread of the internal fire.

[0033] The fire control box for the energy storage equipment in the embodiment of the present application will be described in detail below with reference to the accompanying drawings.

[0034] As Figures 1 to 5As shown, the fireproof control box for energy storage device of the embodiment of the present application comprises a box body, energy storage assemblies 3, a blocking assembly and a fire extinguishing assembly. The box body comprises a lower cabinet body 1 and an upper cabinet body 2, and the lower cabinet body 1 is detachably connected with the upper cabinet body 2 by bolts. The lower cabinet body 1 is provided with a plurality of energy storage assemblies 3. The upper cabinet body 2 is rectangular, and the four peripheral walls of the upper cabinet body 2 are provided with ventilation holes 4 to improve the ventilation effect and meet the heat dissipation requirements of the energy storage assemblies 3.

[0035] The blocking assembly is arranged in the upper cabinet body 2. The blocking assembly comprises a plurality of baffles 5, the baffles 5 are rotatably connected with the upper cabinet body 2, and the plurality of baffles 5 correspond to the plurality of groups of ventilation holes 4 one by one. In a first state, the baffles 5 are horizontally arranged, and the plurality of baffles 5 jointly form a complete partition plate to divide the inner cavity of the upper cabinet body 2 into a first chamber and a second chamber. In a second state, the baffles 5 are vertically arranged, and the baffles 5 block the corresponding ventilation holes 4.

[0036] The blocking assembly further comprises a mounting frame 9, a sliding column 10 and an execution member 12. The mounting frame 9 is cross-shaped, and the mounting frame 9 is connected with the inner peripheral wall of the upper cabinet body 2. The sliding column 10 is slidably arranged at the center of the mounting frame 9 in the vertical direction, and the upper end of the sliding column 10 is in contact with the plurality of baffles 5 to support the horizontal arrangement of the plurality of baffles 5. The lower end of the sliding column 10 is provided with an end plate 11, and the execution member 12 is arranged between the end plate 11 and the mounting frame 9 to limit the downward sliding of the sliding column 10. The execution member 12 is made of glass, and the execution member 12 is filled with an expansion medium. The expansion medium expands to break the execution member 12 when heated.

[0037] It should be noted that the execution member 12 is similar to the glass ball in the fire sprinkler, and the working principle is that when a fire occurs, the ambient temperature rises, the expansion medium (organic solution) in the glass ball expands when heated, and when the temperature reaches the action temperature of the glass ball, the glass ball breaks due to the increase in internal pressure.

[0038] When a fire occurs in the energy storage assembly 3, the temperature in the box body rises to the action temperature of the organic solution in the execution member 12, the execution member 12 breaks, the broken execution member 12 loses the end position limiting and support of the sliding column 10, and therefore the sliding column 10 slides downward under the gravity of itself and the baffles 5, thereby losing the support and blocking of the end of the baffle 5, and then the baffle 5 deflects downward along the end thereof until it is attached to the inner wall of the upper cabinet body 2, thereby fully covering the ventilation holes 4 to prevent oxygen from entering the ventilation holes 4, thereby controlling the combustion of the internal fire. At the same time, when the baffle 5 deflects downward, the fire extinguishing assembly moves downward to act on the lower energy storage assembly 3, thereby covering and extinguishing the ignition point of the energy storage assembly 3.

[0039] Therefore, under normal conditions, heat can be dissipated through the ventilation hole 4 to ensure the working effect of the internal energy storage component 3. When a fire occurs inside, as the actuator 12 breaks, the baffle 5 will automatically deflect downward to block the ventilation hole 4, preventing oxygen from entering. At the same time, the fire extinguishing component will extinguish the fire in the energy storage component 3 to prevent the fire from spreading.

[0040] Optionally, the fire extinguishing assembly includes multiple sets of fire extinguishing balls 8, each set corresponding to and connected to multiple baffles 5. The fire extinguishing balls 8 are made of elastic membrane material and filled with a flame-retardant medium. The outer surface of the fire extinguishing ball 8 is fixed to the baffle 5. The fire extinguishing ball 8 consists of an outer elastic membrane and an inner fire extinguishing dry powder, mainly including ABC dry powder and sodium bicarbonate dry powder (BC dry powder), etc. Of course, the fire extinguishing ball 8 can also be filled with fire extinguishing gases such as carbon dioxide. When filling with gas, a counterweight should be installed inside the fire extinguishing ball 8 to increase its falling kinetic energy.

[0041] The sealing assembly also includes a driving component and multiple corresponding limiting components and multiple piercing components. The driving component is located on the mounting bracket 9, and the multiple piercing components correspond one-to-one with multiple sets of fire extinguishing balls 8. The piercing components are connected to the driving component and are used to pierce the fire extinguishing balls 8 by being driven by the driving component. The limiting components are connected to the driving component and are used to restrict the driving component from driving the piercing components. When the sealing assembly transitions from the first state to the second state, the baffle 5 deflects and moves the limiting components to release the restriction on the driving component.

[0042] Optionally, the driving component includes a sleeve 13, a slip ring 15 and a first spring 17 sleeved on the sleeve 13. The sleeve 13 is sleeved on the sliding column 10. The lower end of the sleeve 13 is connected to the mounting bracket 9. The upper end of the first spring 17 abuts against the slip ring 15 and the lower end of the first spring 17 abuts against the mounting bracket 9. The slip ring 15 is disposed in the annular groove 16.

[0043] The puncture device includes a transverse plate 24 and a conical body 25. One end of the transverse plate 24 is connected to the slip ring 15, and the conical body 25 is located at the other end of the transverse plate 24.

[0044] The limiting component includes an L-shaped plate 18, a connecting plate 19, and a vertical plate 20 connected sequentially from the inside to the outside. The L-shaped plate 18, the connecting plate 19, and the vertical plate 20 generally form a U-shaped bracket with the opening facing upward. One end of the L-shaped plate 18 is movably inserted into the annular groove 16, and the connecting plate 19 is slidably mounted on the mounting frame 9.

[0045] The baffle 5 deflects and moves the vertical plate 20 so that one end of the L-shaped plate 18 is pulled out of the annular groove 16, the first spring 17 drives the slip ring 15 to slide upward, and the cone 25 pierces the fire extinguishing ball 8.

[0046] Specifically, when the actuator 12 breaks, the sliding column 10 slides downward, at which time the baffle 5 deflects downward, and the end of the baffle 5 contacts the vertical plate 20, thereby driving the vertical plate 20 to move closer to the inner wall of the upper cabinet 2, thereby pulling the end of the L-shaped plate 18 out of the annular groove 16. At this time, the sliding ring 15 moves upward under the action of the first spring 17 (the first spring 17 is normally in a compressed state), thereby driving the horizontal plate 24 to move upward, thereby causing the cone 25 to move upward and contact the fire extinguishing ball 8 set on the surface of the baffle 5, causing its outer elastic membrane to break, thereby allowing the fire extinguishing dry powder to be discharged to achieve fire control.

[0047] It should be noted that, in this embodiment of the invention, the accumulated fire extinguishing dry powder is packaged into an elastic membrane to prevent it from getting damp, and it is also convenient to store and deploy. At the same time, the fire extinguishing dry powder inside the elastic membrane is discharged by impact, which can disperse the fire extinguishing dry powder by impact, so that its falling coverage area is wider and more uniform.

[0048] The cone 25 should be positioned directly below the fire extinguishing ball 8 after the baffle 5 has rotated. The slip ring 15 will only move upwards after the baffle 5 contacts the vertical plate 20. This linkage ensures that the cone 25 punctures the fire extinguishing ball 8 only after the baffle 5 has closed the ventilation hole 4 and reached its designated position. This prevents the cone 25 from moving upwards during the baffle 5's rotation, which could cause motion interference and prevent the cone 25 from contacting the fire extinguishing ball 8.

[0049] Optionally, the limiting component also includes a connecting block 22, a sliding shaft 21, and a second spring 23. The connecting block 22 is connected to the connecting plate 19 and is slidably sleeved on the sliding shaft 21. The sliding shaft 21 is horizontally positioned, and one end of the sliding shaft 21 near the sleeve 13 is connected to the sleeve 13. The second spring 23 is sleeved on the sliding shaft 21, with one end of the second spring 23 abutting against the connecting block 22 and the other end of the second spring 23 abutting against the sleeve 13. The second spring 23 is used to keep one end of the L-shaped plate 18 inserted into the annular groove 16.

[0050] The sliding shaft 21 and connecting block 22 are designed to limit the displacement of the connecting plate 19 and prevent it from tipping over. Additionally, the sliding shaft 21 and connecting block 22 can be provided with protrusions and grooves respectively to prevent the connecting plate 19 from rotating. The second spring 23 prevents vibrations and other factors from causing the end of the L-shaped plate 18 to disengage from the annular groove 16, thus preventing the slip ring 15 from moving upwards when the fire is not ignited.

[0051] Optionally, the driving component also includes a third spring 14. The third spring 14 is sleeved on the sliding post 10, with its upper end connected to the upper end of the sliding post 10 and its lower end connected to the upper end of the sleeve 13. The third spring 14 applies a force to the sliding post 10 to slide downward.

[0052] When the actuator 12 breaks, the third spring 14 is used to drive the sliding column 10 to move downward. That is, under normal conditions, the third spring 14 is in a stretched state. When the actuator 12 breaks, the third spring 14 returns to its original position, which will drive the sliding column 10 to slide down, thereby increasing the sliding speed and effect of the sliding column 10 and avoiding interference between the sliding column 10 and the deflection of the baffle 5.

[0053] Optionally, the inner wall of the upper cabinet 2 is provided with a groove (not shown in the figure) that matches the upright plate 20, and the upright plate 20 can slide into the groove. That is, the upright plate 20 is completely inserted into the groove, avoiding the situation where the upright plate 20 is located between the baffle 5 and the inner wall of the upper cabinet 2, which would cause the baffle 5 to not seal the ventilation hole 4 properly.

[0054] Optionally, the piercing element also includes contact plates 26 symmetrically arranged on both sides of the cone 25. The contact plates 26 are L-shaped, with one end connected to the transverse plate 24 and the other end located below the transverse plate 24 and parallel to the surface of the transverse plate 24.

[0055] Under the action of the first spring 17, the contact plate 26 will have an initial upward velocity, thus colliding with the extinguishing dry powder discharged from the fire extinguishing ball 8, causing the extinguishing dry powder to fall downwards in a more dispersed manner. The contact plate 26 is positioned such that the impact surface between the contact plate 26 and the extinguishing dry powder is located below the cone 25. That is, after the fire extinguishing ball 8 is punctured, the extinguishing dry powder inside will fall downwards a certain distance, and after accumulating a certain initial velocity, it will collide with the contact plate 26. Since both the extinguishing dry powder and the contact plate 26 have a certain initial velocity, the force of their collision is greater, resulting in a better dispersion effect on the extinguishing dry powder.

[0056] Optionally, the edge of the baffle 5 is provided with a connecting shaft 7, and the connecting shaft 7 is provided with a fixed shaft 6. One end of the fixed shaft 6 is rotatably connected to the connecting shaft 7, and the other end of the fixed shaft 6 is connected to the inner peripheral wall of the upper cabinet 2. A torsion spring (not shown in the figure) is provided at the connection between the connecting shaft 7 and the fixed shaft 6. The torsion spring applies a force to the baffle 5 to deflect downward. The torsion spring can increase the deflection torque of the baffle 5, thereby ensuring its movement operation of pushing the upright plate 20.
