Description

Technical Field

[0001] This invention relates to the field of energy storage cabinet technology, specifically to an integrated industrial and commercial energy storage unit. Background Technology

[0002] With the development of the new energy industry, energy storage systems are being used more and more widely in industrial and commercial sectors. As a core piece of equipment, the energy storage cabinet contains densely packed battery boxes that generate a large amount of heat during charging and discharging, posing a risk of thermal runaway and fire.

[0003] Current technologies rely on manual firefighting after fire detection or automatic activation of a comprehensive fire suppression system to spray extinguishing agents over a large area inside the energy storage cabinet. Firstly, existing fire suppression methods are ineffective against fires originating behind the battery compartments, as the extinguishing agent cannot directly and accurately target the source, resulting in limited extinguishing efficiency and potential damage to the normal battery compartments. Secondly, fans cannot prevent outside air from entering the energy storage cabinet during a fire, potentially fueling the flames. Thirdly, there is a lack of capability to forcibly remove high-temperature smoke and residual flammable gases after fire suppression, posing a risk of reignition.

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0024] First embodiment: Combined with appendix Figures 1-8 This invention discloses an integrated industrial and commercial energy storage unit, which mainly includes a cabinet 1 and multiple battery boxes 11, a fire-fighting structure 2, a flame-retardant structure 3 and a control unit installed therein; when the battery box 11 catches fire, the fire-fighting structure 2 extinguishes the fire at the ignition point, while the flame-retardant structure 3 assists in preventing the fire from spreading.

[0025] Specifically, the fire protection structure 2 includes a piercing nozzle 21, a swinging spray plate 22, a moving component 23, and a fire storage box 24. The swinging spray plate 22 and the piercing nozzle 21 are both located on the rear side of multiple battery boxes 11 and are connected to the fire storage box 24. The swinging spray plate 22 can swing to spray fire extinguishing agent, achieving large-area fire extinguishing. The piercing nozzle 21 can accurately inject fire extinguishing agent for a single fire source in a battery box 11. The moving component 23 drives the swinging spray plate 22 and the piercing nozzle 21 to move vertically, adjusting the position of the swinging spray plate 22 and the piercing nozzle 21 to change the range of fire extinguishing agent action.

[0026] Then, the flame-retardant structure 3 includes a heat dissipation component 31 and a sealing component 32; wherein, the heat dissipation component 31 includes a fan 311, an air inlet 312 and multiple heat dissipation windows 313; the air inlet 312 is located at the bottom of the cabinet 1, the fan 311 is located above the air inlet 312, and the heat dissipation windows 313 are located at the upper part of the two side walls of the cabinet 1; wherein, the sealing component 32 includes multiple sealing plates 321 and a driving part, the sealing plates 321 cooperate with the heat dissipation windows 313, and the driving part is connected to the sealing plates 321 and the inside of the cabinet 1 respectively, in a normal state In this state, the fan 311 draws air from outside the cabinet 1 into the cabinet 1 through the air inlet 312 to cool the battery box 11. The sealing plate 321 remains in the stored state, and the hot air drifts out through the heat dissipation windows 313 on both sides. After detecting a fire, the fan 311 flips and discharges the air from the air inlet 312 to the outside of the cabinet 1. The sealing plates 321 on both sides block the corresponding heat dissipation windows 313, thereby reducing the air inside the cabinet 1, suppressing the flame combustion, and also expelling the toxic gases produced by the combustion inside the cabinet 1.

[0027] Furthermore, the control unit (PLC controller) is installed inside the cabinet 1 and is electrically connected to the moving component 23 of the fire-fighting structure 2 and the drive mechanism and fan 311 of the flame-retardant structure 3, and is used to control the operation of the fire-fighting structure 2 and the flame-retardant structure 3 according to the fire signal.

[0028] Second embodiment: To provide a detailed description of the specific structure of the piercing nozzle 21 and the oscillating spray plate 22 of the fire protection structure 2, the present invention provides a second embodiment. Specifically, the fire storage box 24 is installed on the top of the cabinet 1 and stores fire extinguishing agent (such as perfluorohexanone). The connecting block 25 is located on the rear side inside the cabinet 1 and is connected to the fire storage box 24 through the first telescopic pipe 26. The piercing nozzle 21 and the oscillating spray plate 22 are both installed at the front end of the connecting block 25.

[0029] Furthermore, the puncture nozzle 21 includes, from front to back, a puncture needle 211, a second telescopic tube 212, and a fixed tube 213. The fixed tube 213 is fixed to the connecting block 25 and communicates with its interior. It is worth noting that the second telescopic tube 212 is a flexible telescopic tube. The two ends of the first electric telescopic rod 214 and the guide telescopic rod 215 are respectively connected to the fixed tube 213 and the outer shell of the puncture needle 211, which are used to drive the needle to move back and forth to realize the puncture action.

[0030] Meanwhile, the swing spray plate 22 includes a hollow connecting plate 221 with multiple spray holes 222 at its front end. The connecting plate 221 is connected to the connecting block 25 through a hose 223. A second electric telescopic rod 225 is hinged between the connecting plate 221 and the connecting block 25. By controlling the extension and retraction of the second electric telescopic rod 225, the connecting plate 221 can be driven to swing within a certain angle range, thereby changing the spray coverage angle of the extinguishing agent. The auxiliary rotating part 224 is used to support and guide the bending of the hose 223. It should be noted that control valves are provided on the connecting pipes of the fixed pipe 213, the hose 223, the first telescopic pipe 26 and the connecting block 25 to control the flow direction of the extinguishing agent.

[0031] In summary, the workflow of fire protection structure 2 will be described in detail below: First, the control unit locates the layer where the faulty battery box 11 is located based on the alarm signal, controls the drive motor 234 of the moving component 23 to operate, moves the puncture nozzle 21 and the swing spray plate 22 to a height aligned with the rear of the battery box 11 on that layer, and then controls the first electric telescopic rod 214 of the puncture nozzle 21 to move, pushing the puncture needle 211 forward to pierce the box of the faulty battery box 11.

[0032] When the puncture needle 211 is inserted, the control unit opens the control valve on the pipeline connected to the puncture nozzle 21. Under pressure, the extinguishing agent in the fire storage box 24 passes through the first telescopic tube 26, the connecting block 25, the fixed tube 213, and the second telescopic tube 212, and is finally injected directly into the battery box 11 from the nozzle at the front end of the puncture needle 211 to extinguish the fire at its source. At the same time, the control valve on the pipeline connected to the swing spray plate 22 is opened, and the extinguishing agent enters the connecting plate 221 through the hose 223 and is sprayed forward in a fan shape from multiple spray holes 222. The second electric telescopic rod 225 is controlled to reciprocate and extend to a certain extent, causing the connecting plate 221 to swing, so that the extinguishing agent covers the rear area of ​​the faulty battery box 11 and its adjacent battery boxes 11, suppressing the spread of the flames. Of course, if the fire is large, the moving component 23 drives the connecting plate 221 to swing and move up and down, so that the extinguishing agent covers the inside of the cabinet 1.

[0033] Third embodiment: Based on the above embodiments, the composition of the moving component 23 is described in detail. The present invention provides a third embodiment. Specifically, the moving component 23 is used to drive the entire connecting block 25 and its front-end nozzle assembly to move vertically. It includes a vertically arranged lead screw 231, a threaded block 232 that is threadedly engaged with the lead screw 231, a parallel guide rod 233, and a drive motor 234. The drive motor 234 drives the lead screw 231 to rotate, causing the threaded block 232 to slide up and down along the guide rod 233. The threaded block 232 is fixedly connected to the rear end of the connecting block 25, thereby achieving precise positioning so that the piercing nozzle 21 can be aimed at the rear of any battery box 11. This position is usually the surface where the battery pressure relief valve or weak point is located. Moreover, when the fire is large, the moving component 23 can drive the connecting plate 221 to move up and down so that the extinguishing agent covers the inside of the cabinet 1.

[0034] Fourth embodiment: To provide a detailed description of the specific components of the heat dissipation assembly 31 and the sealing assembly 32 of the flame-retardant structure 3, the present invention also provides a fourth embodiment. Specifically, the heat dissipation assembly 31 is used for heat dissipation under normal operating conditions. The air inlet 312 is opened at the bottom of the cabinet 1. The fan 311 is fixed above the air inlet 312 by the mesh plate 314. Multiple heat dissipation windows 313 are opened on the upper part of the two side walls of the cabinet 1. During normal operation, the fan 311 rotates forward, drawing in external cold air from the bottom air inlet 312. After flowing through the gap of the battery box 11 and carrying away the heat, it is discharged from the heat dissipation windows 313 on both sides.

[0035] Meanwhile, the sealing component 32 is used for sealing and flame retardancy in fire conditions. Inside each heat dissipation window 313, a storage cavity 322 with an open top is provided in the wall of the cabinet 1. The sealing plate 321 is movably inserted into the storage cavity 322. The driving part is a third electric telescopic rod 323, whose upper and lower ends are fixedly connected to the bottom of the sealing plate 321 and the storage cavity 322, respectively. Under normal conditions, the third electric telescopic rod 323 retracts, the sealing plate 321 is stored in the cavity, and the heat dissipation window 313 is unobstructed. When the fire command is issued, the third electric telescopic rod 323 extends and pushes the sealing plate 321 up until the heat dissipation window 313 is completely blocked, cutting off the air circulation path. It should be noted that dustproof nets are provided on the air inlet 312 and the heat dissipation window 313 to prevent dust and other debris from entering the cabinet 1 during normal heat dissipation.

[0036] During normal heat dissipation, the fan 311 rotates forward, the sealing plate 321 retracts, and the heat dissipation window 313 and air inlet 312 are unobstructed, allowing the equipment to dissipate heat normally. When a sudden rise in temperature or smoke is detected inside the cabinet 1, the control unit controls all the third electric telescopic rods 323 to move synchronously, raising all the sealing plates 321, closing all the heat dissipation windows 313, and controlling the fan 311 to stop rotating forward and switch to reverse mode, so that the air inside the cabinet 1 is exhausted to the outside, reducing the internal oxygen content and suppressing the degree of flame combustion.

[0037] Next, after the operation of fire protection structure 2 is completed, the cabinet is filled with high-temperature smoke and residual combustible gas. Since the fan 311 is in reverse and the heat dissipation window 313 has been blocked, the fan 311 draws in the high-temperature gas from the top of the cabinet 1 through the space around the fire protection structure 2 and forces it out of the cabinet through the bottom air inlet 312, which serves as the smoke exhaust outlet. This accelerates the cooling of the cabinet and the removal of harmful gases, reducing the risk of reignition. After the fire is confirmed to be completely extinguished and the temperature inside the cabinet drops to a safe range, all mechanisms can be reset through the control unit for the next use.

[0038] Fifth embodiment: Based on the above embodiments, in order to enable the control unit to quickly receive signals when a fire occurs, so as to control the fire protection structure 2 and the flame-retardant structure 3 to respond quickly, a fire detector 4 is installed on the inner wall of the cabinet 1 near each battery box 11. It can sense temperature and smoke. The control unit is installed inside the cabinet 1, and its signal input terminal is connected to all fire detectors 4. The control output terminal is electrically connected to all actuators such as the drive motor 234, the control valves of the first electric telescopic rod 214, the second electric telescopic rod 225, the fan 311, and the third electric telescopic rod 323.

[0039] The present invention and its embodiments have been described above. This description is not restrictive. The accompanying drawings are only one embodiment of the present invention. The actual structure is not limited to this. In short, if a person skilled in the art is inspired by this description and designs a similar structure and embodiment without departing from the spirit of the present invention, such design should fall within the protection scope of the present invention.
