Description
Technical Field
[0001] This utility model relates to the field of energy storage cabinet technology, specifically to an energy storage cabinet and an energy storage system. Background Technology
[0002] When a severe thermal runaway occurs in an energy storage system, a water flooding method must be used to control it and prevent the heat from spreading.
[0003] Publication No. CN220558446U discloses a graded early warning fire emergency response system for energy storage cabinets. The system sets different fire alarm levels for the internal state of the energy storage cabinet by combining the operation platform with the analysis data. After reaching the threshold of different levels, the system controls the electrochemical fire extinguishing device and PACK-level (for the fire protection and safety management system at the battery pack level) nozzles to perform range cooling or to perform flood extinguishing through fine water mist nozzles, based on the parameters.
[0004] However, energy storage system cabinets are usually equipped with drains to prevent coolant leaks and condensation. When a fire occurs and water is used for flooding, the simultaneous opening of the sprinklers and drains reduces flooding efficiency or even prevents flooding from being completed. Utility Model Content
[0005] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and propose an energy storage cabinet and energy storage system. This solves the technical problem that in the prior art, the cabinet of the energy storage system is usually equipped with a drain to prevent coolant leakage and condensation. When a fire occurs and water is used for flooding, the sprinkler head and the drain are opened at the same time, which reduces the flooding efficiency or even makes flooding impossible.
[0006] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution:
[0007] This utility model provides an energy storage cabinet, comprising:
[0008] The cabinet has an energy storage cavity;
[0009] A flow guide pipe is located at the bottom of the cabinet and has a flow guide end for connecting to the outside of the cabinet;
[0010] A spray pipe, located within the cabinet and connected to the flow guide pipe, has a spray end extending into the energy storage chamber; and
[0011] A drain pipe is located at the bottom of the cabinet and connects the guide pipe to the energy storage chamber. The connection between the drain pipe and the energy storage chamber is located on the bottom wall of the energy storage chamber.
[0012] In some embodiments, the energy storage cabinet further includes a cover, which is installed on the flow guide pipe and located at the flow guide end, and has a through hole connecting the outside to the inside of the flow guide pipe.
[0013] In some embodiments, the cap is detachably connected to the flow channel.
[0014] In some embodiments, the cap is threadedly connected to the flow channel.
[0015] In some embodiments, the cover includes a sealing body, a flow sleeve, and a snap-fit sleeve. The cover is installed on the flow guide pipe and located at the flow guide end. The flow sleeve and the snap-fit sleeve are installed on the side of the cover away from the flow guide end. The snap-fit sleeve is spaced apart inside the flow sleeve.
[0016] The through hole is formed in the sealing body and located inside the snap-fit sleeve.
[0017] In some embodiments, the cap further includes a diversion protrusion, which is installed on the sealing body and located on the same side of the sealing body as the snap-fit sleeve, and is located inside the snap-fit sleeve;
[0018] The vias are provided in multiple locations, and the multiple vias are arranged at intervals along the circumference of the diversion protrusion.
[0019] In some embodiments, the inner diameters of both the guide pipe and the spray pipe are larger than the inner diameter of the drain pipe.
[0020] In some embodiments, the communication ports are provided in multiple locations, and the multiple communication ports are spaced apart; and / or,
[0021] The energy storage cabinet also includes a filter plate, which is located at the communication port.
[0022] In some embodiments, the drain pipe has a drain section that communicates with the energy storage chamber, and the drain section is gradually narrowed in a direction away from the energy storage chamber;
[0023] The connection port is formed at the junction of the drainage section and the energy storage cavity.
[0024] In addition, this utility model also provides an energy storage system, which includes the energy storage cabinet as described in any of the above claims.
[0025] Compared with existing technologies, the energy storage cabinet provided by this utility model allows the liquid in the energy storage chamber to accumulate on the bottom wall during drainage. The liquid then flows through the connecting port into the drainage pipe at the bottom of the energy storage chamber, and then sequentially flows through the guide pipe before being discharged from the guide end of the guide pipe, thus preventing liquid accumulation in the energy storage chamber. In the event of a fire in the energy storage chamber requiring flooding, an external water source is connected to the guide end. Most of the externally input water flows through the guide pipe to the sprinkler pipe and is sprayed into the energy storage chamber to extinguish the fire. Simultaneously, a small portion of the water flows through the guide pipe to the drainage pipe and is then transported back into the energy storage chamber.
[0026] In this way, the solution retains the drainage function and allows the spray pipe and drainage pipe to simultaneously supply water to the energy storage chamber during flood irrigation, effectively avoiding the spray pipe and drainage pipe entering and exiting at the same time, improving flood irrigation efficiency, thereby improving the safety of the energy storage cabinet, and the structure is simple and cost-saving.

[0037] 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.
[0038] To address the technical problem that existing energy storage system cabinets typically have drainage drains to prevent coolant leakage and condensation, and that the simultaneous opening of the sprinkler heads and drainage drains during flood irrigation reduces irrigation efficiency or even prevents complete irrigation, this invention provides an energy storage cabinet that retains the drainage function while simultaneously supplying water to the energy storage chamber via both the sprinkler and drainage pipes during flood irrigation. This effectively avoids the sprinkler and drainage pipes flowing in and out separately, improving irrigation efficiency and thus enhancing the safety of the energy storage cabinet. Furthermore, the design is simple and cost-effective.
[0039] It should be noted that the energy storage cabinet described in this utility model is used in, but not limited to, energy storage systems. For ease of explanation, this utility model only uses the application of the energy storage cabinet in an energy storage system as an example for explanation. The principle of the energy storage cabinet applied to other types of equipment is essentially the same as that applied to an energy storage system, and will not be described in detail here.
[0040] Please see Figures 1 to 4 , Figures 1 to 4 This is a schematic diagram of the energy storage cabinet in one embodiment of the present invention. The energy storage cabinet includes a cabinet body 1, a guide pipe 2, a spray pipe 3, and a drain pipe 4. The cabinet body 1 has an energy storage cavity 1a. The guide pipe 2 is located at the bottom of the cabinet body 1 and has a guide end 21 for connecting to the outside of the cabinet body 1. The spray pipe 3 is located in the cabinet body 1 and connected to the guide pipe 2, and has a spray end 31 extending into the energy storage cavity 1a. The drain pipe 4 is located at the bottom of the cabinet body 1 and connects the guide pipe 2 and the energy storage cavity 1a. The connection port 4a between the drain pipe 4 and the energy storage cavity 1a is located on the bottom wall of the energy storage cavity 1a. Specifically, in this embodiment, both the guide pipe 2 and the drain pipe 4 are located at the bottom of the energy storage cavity 1a. Furthermore, the height of the guide pipe 2 is not higher than the height of the drain pipe 4.
[0041] In the energy storage cabinet provided by this utility model, during liquid drainage, the liquid in the energy storage chamber 1a accumulates on the bottom wall and enters the drainage pipe 4 at the bottom of the energy storage chamber 1a through the connecting port 4a. It then flows through the drainage pipe 4 to the guide pipe 2 and is discharged from the guide end 21 of the guide pipe 2, preventing liquid accumulation in the energy storage chamber 1a. When a fire occurs in the energy storage chamber 1a requiring flooding, an external water source is connected to the guide end 21. Most of the externally input water flows through the guide pipe 2 to the spray pipe 3 and is sprayed into the energy storage chamber 1a to extinguish the fire. Simultaneously, a small portion of the water flows through the guide pipe 2 to the drainage pipe 4 and is transported back to the energy storage chamber 1a.
[0042] In this way, the solution retains the drainage function and allows the spray pipe 3 and the drainage pipe 4 to simultaneously supply water to the energy storage chamber 1a during flood irrigation, effectively avoiding the situation where the spray pipe 3 and the drainage pipe 4 enter and exit at the same time, improving flood irrigation efficiency, thereby improving the safety of the energy storage cabinet. Moreover, the structure is simple and saves costs.
[0043] It should be noted that the cabinet 1 can be configured as a cuboid, cylindrical, or irregularly shaped structure with chambers. Specifically, in this embodiment, the cabinet 1 is configured as a cuboid. Furthermore, to improve fire extinguishing efficiency, in one embodiment, the spray end 31 of the sprinkler pipe 3 is equipped with a spray head, so that while achieving flooding, the water flow can also be dispersed, thereby improving fire extinguishing capability.
[0044] It should be understood that the spray end 31 can be located at the top, middle or other positions of the energy storage chamber 1a, as long as it is higher than the bottom wall of the energy storage chamber 1a. To ensure the spraying effect, the height of the spray end 31 is set according to the water injection pressure to ensure that the water flow sprayed from the spray end 31 can reach the top of the energy storage chamber 1a.
[0045] In one embodiment, please refer to Figures 5 to 7 The energy storage cabinet also includes a cover 5, which is installed on the flow guide pipe 2 and located at the flow guide end 21, and has a through hole 5a connecting the outside to the inside of the flow guide pipe 2.
[0046] In this embodiment, a cover 5 is provided at the guide end 21, and water flows through the through hole 5a on the cover 5 to prevent external debris or animals from entering the energy storage chamber 1a through the pipe.
[0047] In one embodiment, the cap 5 is detachably connected to the flow channel 2.
[0048] In this embodiment, when flood irrigation is needed, the cap 5 is removed from the guide end 21, and the water source is then sent into the energy storage chamber 1a through the guide end 21 to improve flood irrigation efficiency. When flood irrigation is not needed, the cap 5 is installed on the guide end 21 to prevent foreign objects from entering the energy storage chamber 1a.
[0049] It should be noted that the cap 5 and the diversion pipe 2 can be detachably connected by bolts, clips or other structures.
[0050] In one embodiment, the cap 5 is threadedly connected to the flow channel 2.
[0051] In this embodiment, the cap 5 can be easily installed and removed simply by rotating it in both directions. It should be noted that in this design, the cap 5 is fitted onto the outside of the guide pipe 2, and the inner wall of the cap 5 has internal threads; correspondingly, the outer wall of the guide pipe 2 has external threads.
[0052] It should be noted that, in one embodiment, the energy storage cabinet is assembled and welded from carbon steel and insulation materials, and has the function of supporting, fixing, and protecting the internal equipment. The diversion pipe 2, spray pipe 3, and drainage pipe 4 are mainly composed of cast iron and welded carbon steel pipes, assembled using bolted connections or welding processes, and are used as channels for liquid injection and discharge.
[0053] In one embodiment, the cover 5 includes a sealing body 51, a flow sleeve 52, and a snap-fit sleeve 53. The cover 5 is installed on the flow guide pipe 2 and located at the flow guide end 21. The flow sleeve 52 and the snap-fit sleeve 53 are installed on the side of the cover 5 away from the flow guide end 21. The snap-fit sleeve 53 is spaced apart in the flow sleeve 52. The through hole 5a is formed in the sealing body 51 and located in the snap-fit sleeve 53.
[0054] In this embodiment, a snap-fit gap 53a is formed between the snap-fit sleeve 53 and the flow sleeve 52, so that in an emergency, the external water source pipe can be directly snapped into the snap-fit gap 53a and injected through the through hole 5a. After the fire is somewhat relieved, the cover 5 can be removed to inject water.
[0055] It should be noted that in one embodiment, there are two flow guide ends 21. The energy storage cabinet also includes a sealing plug, which is detachably installed on the two flow guide ends 21 along with the cover 5. This allows for rapid water intake in emergencies by directly inserting an external water pipe into the snap-fit gap 53a of the cover 5. The sealing plug can then be removed, and the water can be directly introduced into the external water source via its corresponding flow guide end 21. This approach alleviates emergency situations while ensuring efficient water injection.
[0056] In this embodiment, the sealing plug and the guide end 21 can be detachably connected by bolts, clips, or other means. Specifically, the sealing plug and the guide end 21 are also connected by threads. Furthermore, the positions of the sealing plug and the cap 5 are interchangeable.
[0057] In one embodiment, the cover 5 further includes a diversion protrusion 54, which is installed on the sealing body 51 and is located on the same side of the sealing body 51 as the snap sleeve 53, and is located inside the snap sleeve 53; multiple through holes 5a are provided, and the multiple through holes 5a are arranged at intervals along the circumference of the diversion protrusion 54.
[0058] In this embodiment, the water flow entering the flow sleeve 52 is dispersed by the diversion protrusion 54, so that the water flow can enter the guide pipe 2 evenly through multiple through holes 5a. Specifically, in this solution, the end of the diversion protrusion 54 away from the sealing body 51 is provided with an arc-shaped convex surface.
[0059] In one embodiment, please refer to Figure 8 The inner diameters of both the diversion pipe 2 and the spray pipe 3 are larger than the inner diameter of the drainage pipe 4.
[0060] In this embodiment, the inner diameters of both the diversion pipe 2 and the spray pipe 3 are set to be larger than the inner diameter of the drain pipe 4 to ensure that water can be quickly introduced into the energy storage chamber 1a and improve the water intake efficiency.
[0061] In one embodiment, multiple connection ports 4a are provided, and the multiple connection ports 4a are spaced apart; the energy storage cabinet also includes a filter plate 6, which is provided at the connection port 4a.
[0062] In this embodiment, multiple connecting ports 4a are provided. This improves the drainage efficiency of the collected liquid in the energy storage chamber 1a, ensuring the drainage capacity of the floor drain. Furthermore, during flooding, it allows external water to enter the energy storage chamber 1a relatively evenly, enhancing the fire extinguishing effect. Simultaneously, filter plates 6 are installed at the connecting ports 4a to prevent pipe blockage caused by equipment damage within the energy storage chamber 1a. The spray nozzles at the spray end 31 prevent blockage.
[0063] Specifically, in this scheme, there are two connecting ports 4a, and correspondingly, there are also two filter plates 6, which are installed at the two connecting ports 4a respectively.
[0064] In one embodiment, the drain pipe 4 has a drain section 41 that connects to the energy storage cavity 1a, and the drain section 41 is gradually narrowed in the direction away from the energy storage cavity 1a; the connection port 4a is formed at the connection between the drain section 41 and the energy storage cavity 1a.
[0065] In this embodiment, the drainage section 41 is set as an inverted cone shape to further improve the efficiency of liquid collection and drainage.
[0066] Furthermore, this utility model also provides an energy storage system, which includes the energy storage cabinet as described in any of the above embodiments. It should be noted that the detailed structure of the energy storage cabinet can be referred to the embodiments of the energy storage cabinet described above, and will not be repeated here. Since the energy storage cabinet described above is used in the energy storage system of this utility model, the embodiments of the energy storage system of this utility model include all the technical solutions of all the embodiments of the energy storage cabinet described above, and the achieved technical effects are also completely the same, and will not be repeated here.
[0067] To better understand this utility model, the following is combined with... Figures 1 to 8 The technical solution of this utility model is described in detail below:
[0068] In this scheme, the working principle of liquid drainage is as follows: the liquid inside the energy storage chamber 1a enters the drainage pipe 4 through the connecting port 4a in the direction indicated by the arrow, then enters the guide pipe 2, and finally is discharged to the outside through the through hole 5a on the cover 5 of the guide end 21.
[0069] The working principle of flood irrigation is as follows: When flood irrigation is required, the cap 5 is removed from the guide end 21, and a large amount of water enters the guide pipe 2 through the guide end 21 and flows to the spray pipe 3 through the guide pipe 2. Finally, it is injected into the energy storage chamber 1a through the spray end 31 of the spray pipe 3. A small amount of water can also enter the energy storage chamber 1a through the connection port 4a of the drain pipe 4, so as to realize the control of thermal runaway by water flood irrigation.
[0070] Thus, this solution integrates the drain drainage and flood irrigation into the same pipe to achieve the function; during flood irrigation, there will be no problem of water being injected on one side and draining from the drain on the other; and the cover 5 of the guide end 21 is designed with a porous structure, which will not affect the drain drainage, and at the same time prevents debris or animals from crawling in.
[0071] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
