Description

Technical Field

[0001] This invention relates to the field of energy storage battery prefabrication technology, specifically to a fireproof and explosion-proof energy storage battery prefabrication. Background Technology

[0002] As the core support for the development of new energy, the energy storage industry and energy storage technology have been rapidly promoted by the rapid development of the wind power and photovoltaic industries in recent years. Under the current background of new energy development, energy storage equipment has become an important auxiliary equipment for the development of the new energy industry at this stage. The increase in the energy density of a single battery cell leads to extremely strict operating conditions. Due to the special location of wind farms, external rescue forces cannot arrive in time. Therefore, how to achieve thermal runaway control is the main problem to be solved at this stage.

[0003] Existing fire extinguishing systems and methods for prefabricated battery compartments in lithium iron phosphate energy storage power stations, such as the one described in announcement CN110496335B, involve installing fine water mist nozzles in each battery module within the prefabricated battery compartment. All these nozzles are connected to a fine water mist fire extinguishing device via a pipeline network to form a fine water mist fire extinguishing system. Simultaneously, gas fire extinguishing system nozzles are also arranged within the prefabricated battery compartment, using a total flooding fire extinguishing method. All these nozzles are connected to a gas fire extinguishing device via a pipeline network to form a gas fire extinguishing system. This invention can effectively extinguish fires in prefabricated battery compartments of lithium iron phosphate energy storage power stations without any substantial impact on unburned battery modules within the compartment. These modules can be reused after recovery, solving a fire safety problem in the field of new energy lithium battery applications, currently considered a global challenge. It also offers rapid fire extinguishing and effectively inhibits the continued occurrence of battery thermal runaway, preventing reignition.

[0004] While the existing prefabricated energy storage battery compartments can effectively extinguish fires in the event of thermal runaway, the fine water mist nozzles and gas extinguishing systems cover the entire compartment, making it impossible to isolate and extinguish individual battery clusters. This can cause short circuits or other problems to battery clusters that have not yet experienced thermal runaway when the fine water mist nozzles spray water, leading to increased losses and higher maintenance costs. Furthermore, the total flooding method of extinguishing fires also increases the cost of firefighting. Summary of the Invention

[0005] The purpose of this invention is to provide a fireproof and explosion-proof prefabricated energy storage battery compartment to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a fireproof and explosion-proof prefabricated energy storage battery compartment, comprising a compartment body, fireproof boards uniformly fixed inside the compartment body, a heptafluoropropane storage tank fixed on the upper surface of the compartment body, water storage tanks symmetrically fixed on the front and rear sides of the compartment body, and a return water tank fixed between the compartment body and the fireproof boards.

[0007] An isolation mechanism, in conjunction with a fireproof board, achieves a spatial sealing and isolation function. The isolation mechanism is installed above the return water tank, and the positions of the isolation mechanism and the fireproof board correspond to each other.

[0008] The regulating mechanism is used to control the movement of the isolation mechanism and regulate the delivery of gas and liquid. The regulating mechanism is installed inside the chamber and is connected to the isolation mechanism.

[0009] Preferably, an outer door is installed on the left side of the cabin, and a fireproof partition is installed inside the cabin. An electrical control cabinet is installed between the cabin and the fireproof partition, and an inner door is installed on the fireproof partition. An industrial air conditioner is installed on the right side of the cabin. The fireproof partition can isolate the battery compartment and the electrical compartment, providing a basic guarantee for the normal operation of the device. The industrial air conditioner can also be used to dissipate heat from the battery compartment.

[0010] Preferably, the heptafluoropropane storage tank is connected to a gas duct fixed to a fireproof board via a conduit, and a solenoid valve is installed on the conduit between the heptafluoropropane storage tank and the gas duct. The gas duct is connected to a gas diversion plate via a first valve, and a first gear is installed on the valve stem of the first valve. Gas nozzles are uniformly fixed on the lower end face of the gas diversion plate. The above structure constitutes a gas fire extinguishing mechanism to ensure the normal operation of fire extinguishing.

[0011] Preferably, a first sealing plate is slidably connected inside the gas diversion plate, and the first sealing plate has a circular hole that mates with the gas nozzle. A first sliding rod that is slidably connected to the gas diversion plate is fixed on the first sealing plate, and a first spring is fixed between the first sliding rod and the gas diversion plate. Through the above structure, a basic guarantee can be provided for releasing the seal of the gas nozzle, thereby providing a basic guarantee for the gas extinguishing.

[0012] Preferably, the upper surface of the water storage tank is equipped with a water inlet, and the two water storage tanks are connected by a connecting pipe. A water pump is installed on the water storage tank, and the water pump is connected to a water guide pipe fixed on the fireproof board through a conduit. The water guide pipe is connected to a water distribution plate through a second valve, and a second gear is fixed on the valve stem of the second valve. Water mist nozzles are evenly fixed on the lower surface of the water distribution plate. The above structure constitutes a water mist fire extinguishing mechanism to ensure the normal operation of fire extinguishing.

[0013] Preferably, a second sealing plate is slidably connected inside the water distribution plate, and the second sealing plate has a round hole that cooperates with the water mist nozzle. A second sliding rod is also fixed on the second sealing plate and slidably connected to the water distribution plate. At the same time, a second spring is fixed between the second sliding rod and the water distribution plate. Through the above structure, a basic guarantee can be provided for releasing the seal of the water mist nozzle, thereby providing a basic guarantee for the water mist fire extinguishing.

[0014] Preferably, the water return tank is symmetrically fixed with guide rails on the left and right, and the guide rails are provided with water return ports. The water return tank is connected to the water storage tank through a water return pipe. Through the above structure, water can be recycled and reused, thereby improving energy utilization and preventing water overflow from affecting other battery clusters.

[0015] Preferably, the isolation mechanism includes an isolation fireproof box disposed above the return water tank, and a slider is fixed at the lower end of the isolation fireproof box. The slider and the guide rail are slidably connected. At the same time, a drain outlet is also fixed at the lower end of the isolation fireproof box. The diameter of the drain outlet is smaller than the inner diameter of the return water pipe. Through the sliding action between the slider and the guide rail, the stability of the movement of the isolation mechanism can be ensured, and through the function of the drain outlet, a basic guarantee can be provided for water recycling.

[0016] Preferably, a support strip is fixed to the lower inner surface of the fireproof isolation box, and side strips are also symmetrically fixed to the inner side of the fireproof isolation box, with the side strips contacting the battery cluster. A smoke sensor and a temperature sensor are also fixed to the upper inner surface of the fireproof isolation box. Through the function of the smoke sensor and temperature sensor, the battery cluster can be monitored to ensure the normal operation of the device. Furthermore, through the function of the side strips and support strips, the flow of water mist and gas can be facilitated to ensure the fire extinguishing effect.

[0017] Preferably, the adjustment mechanism includes an electric telescopic rod fixed inside the cabin, and a movable frame is fixed to the output end of the electric telescopic rod. A third spring is fixed between the movable frame and the isolation fireproof box. At the same time, a guide rod is fixed on the isolation fireproof box. The guide rod and the movable frame are slidably connected. A toothed plate is also fixed on the movable frame. The toothed plate cooperates with the first gear and the second gear to achieve a transmission effect. Through the above structure, the position of the isolation mechanism can be adjusted. And through the transmission effect between the toothed plate and the first gear and the second gear, the opening and closing of the first valve and the second valve can be guaranteed.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. This fireproof and explosion-proof prefabricated energy storage battery compartment can accurately locate thermal runaway battery clusters through smoke and temperature sensors. The controller drives an electric telescopic rod to form a sealed space with the fireproof isolation box and fireproof board, isolating and extinguishing only a single thermal runaway battery cluster. This avoids the leakage of gas and water mist during the fire extinguishing process, which may affect normal battery clusters. This minimizes the loss of non-faulty batteries and reduces the economic losses associated with fire extinguishing. Furthermore, the significantly reduced fire extinguishing space after isolation allows heptafluoropropane gas and water mist to fill the sealed area more quickly, improving the fire extinguishing response speed and extinguishing effect. At the same time, the small space requirement reduces the amount of fire extinguishing gas and water used, directly reducing the consumption cost of fire extinguishing media and achieving efficient and low-cost fire extinguishing.

[0020] 2. In this fireproof and explosion-proof prefabricated energy storage battery compartment, the activation of gas extinguishing and water mist extinguishing does not rely entirely on the electromagnetic valve electrical signal. The toothed plate, the first gear, and the second gear work together to control the operation. Only after the fireproof isolation box is fully in place and forms a sealed space will the mechanical movement trigger the opening of the first and second valves for gas and water. This ensures the strict timing and reliability of the extinguishing and isolation actions, prevents malfunctions, and further enhances the safety of the extinguishing process.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Please see Figures 1-7 The present invention provides a technical solution: a fireproof and explosion-proof prefabricated energy storage battery compartment, including a compartment body 1, fireproof boards 2 are uniformly fixed inside the compartment body 1, a heptafluoropropane storage tank 3 is fixed on the upper surface of the compartment body 1, a water storage tank 4 is symmetrically fixed on the front and back of the outer side of the compartment body 1, and a return water tank 5 is fixed between the compartment body 1 and the fireproof boards 2.

[0031] The isolation mechanism 6, in conjunction with the fireproof board 2, achieves a space sealing and isolation function. The isolation mechanism 6 is installed above the return water tank 5, and the positions of the isolation mechanism 6 and the fireproof board 2 correspond to each other.

[0032] The regulating mechanism 7 is used to control the movement of the isolation mechanism 6 and regulate the delivery of gas and liquid. The regulating mechanism 7 is installed inside the cabin 1 and is connected to the isolation mechanism 6.

[0033] When using this fireproof and explosion-proof prefabricated energy storage battery compartment, such as Figures 1-7As shown, during normal operation of the device, the industrial air conditioner 104 can cool down the battery compartment on the right side, which is composed of the fireproof partition 102 and the cabin 1, to ensure the normal operation of the battery cluster 608. During the operation of the device, when one of the battery clusters 608 catches fire due to thermal runaway, the smoke sensor 606 and the temperature sensor 607 can accurately monitor the position of the thermal runaway battery cluster 608. After determining the position of the thermal runaway battery cluster 608, the controller controls the electric telescopic rod 701 at the corresponding position to extend, thereby driving the movable frame 702, the third spring 703 and the isolation fireproof box 601 to move towards the side of the fireproof board 2. With the sliding action between the slider 602 and the guide rail 501, the stability of the movement of the isolation fireproof box 601 can be ensured.

[0034] The heptafluoropropane storage tank 3 is connected to the gas duct 302 fixed on the fireproof plate 2 via a conduit. A solenoid valve 301 is installed on the conduit between the heptafluoropropane storage tank 3 and the gas duct 302. The gas duct 302 is connected to the gas diversion plate 305 via a first valve 303. A first gear 304 is installed on the valve stem of the first valve 303. Gas nozzles 306 are evenly fixed on the lower end face of the gas diversion plate 305. A first sealing plate 307 is slidably connected inside the gas diversion plate 305. The first sealing plate 307 has a circular hole that mates with the gas nozzle 306, and a... A first sliding rod 308 is slidably connected between the gas diversion plates 305, and a first spring 309 is fixed between the first sliding rod 308 and the gas diversion plates 305. A water inlet 402 is installed on the upper surface of the water storage tank 4, and the two water storage tanks 4 are connected by a connecting pipe 401. A water pump 403 is installed on the water storage tank 4, and the water pump 403 is connected to a water guide pipe 404 fixed on the fireproof plate 2 via a conduit. The water guide pipe 404 is connected to the water distribution plate 407 via a second valve 405, and a second gear 406 is fixed on the valve stem of the second valve 405. Water mist nozzles are evenly fixed on the lower surface of the water distribution plate 407. 408; A second sealing plate 409 is slidably connected inside the water distribution plate 407, and the second sealing plate 409 has a round hole that mates with the water mist nozzle 408. A second sliding rod 410 is also fixed on the second sealing plate 409 and slidably connected to the water distribution plate 407. At the same time, a second spring 411 is fixed between the second sliding rod 410 and the water distribution plate 407. An outer hatch 101 is installed on the left side of the cabin 1, and a fireproof partition 102 is installed inside the cabin 1. An electrical control cabinet is installed between the cabin 1 and the fireproof partition 102. An inner hatch 103 is installed on the fireproof partition 102. An industrial air conditioner 104 is installed on the right side of the cabin 1. The isolation mechanism 6 includes an isolation fireproof box 601 installed above the return water tank 5, and a slider 602 is fixed to the lower end of the isolation fireproof box 601. The slider 602 is slidably connected to the guide rail 501. At the same time, a drain outlet 603 is also fixed to the lower end of the isolation fireproof box 601. The diameter of the drain outlet 603 is smaller than the inner diameter of the return water pipe 503. A support strip 604 is fixed to the lower inner side of the isolation fireproof box 601, and side strips 605 are also symmetrically fixed to the left and right sides of the inner side of the isolation fireproof box 601. The side strips 605 are in contact with the battery cluster 608. A smoke sensor 606 and a temperature sensor 607 are also fixed to the upper inner side of the isolation fireproof box 601.The adjustment mechanism 7 includes an electric telescopic rod 701 fixed inside the cabin 1, and a movable frame 702 is fixed to the output end of the electric telescopic rod 701. A third spring 703 is fixed between the movable frame 702 and the isolation fireproof box 601. Meanwhile, a guide rod 704 is fixed on the isolation fireproof box 601. The guide rod 704 is slidably connected to the movable frame 702. A toothed plate 705 is also fixed on the movable frame 702. The toothed plate 705 cooperates with the first gear 304 and the second gear 406 to achieve a transmission function.

[0035] During the movement of the fireproof isolation box 601, when the inner wall of the fireproof isolation box 601 contacts the second slide rod 410 and the first slide rod 308, because the elastic potential energy of the third spring 703 is much greater than that of the first spring 309 and the second spring 411, when the fireproof isolation box 601 continues to move after contacting the second slide rod 410 and the first slide rod 308, the second slide rod 410 and the first slide rod 308 are moved by force, and the first spring 309 and the second spring 411 are contracted by force. Through the movement of the second slide rod 410 and the first slide rod 308, the second sealing plate 409 and the first sealing plate 307 can be driven simultaneously. The device moves until the round hole on the second sealing plate 409 mates with the position of the water mist nozzle 408, and the round hole on the first sealing plate 307 mates with the position of the gas nozzle 306, thereby releasing the sealing effect of the gas nozzle 306 and the water mist nozzle 408, so that the gas and water mist can be sprayed out later. After releasing the sealing effect of the gas nozzle 306 and the water mist nozzle 408, the isolation fireproof box 601 continues to move until the isolation fireproof box 601 contacts and seals with the fireproof plate 2. At this time, the thermally runaway battery cluster 608 is located in the sealed space formed by the isolation fireproof box 601 and the fireproof plate 2, and the drain outlet 603 is located directly above the return water pipe 503.

[0036] When the fireproof isolation box 601 contacts and seals with the fireproof plate 2, the electric telescopic rod 701 continues to extend. Since the position of the fireproof isolation box 601 is limited at this time, the extension of the electric telescopic rod 701 drives the movable frame 702 to move relative to the fireproof isolation box 601. Combined with the sliding guidance between the guide rod 704 and the movable frame 702, the stability of the movable frame 702's movement is ensured. Simultaneously, the movement of the movable frame 702 drives the toothed plate 705 to move. When the toothed plate 705 meshes with the first gear 304, the first gear 304 can drive the first valve. The valve stem of valve 303 rotates, thereby opening the first valve 303. When the toothed plate 705 meshes with the second gear 406, the second gear 406 can drive the valve stem of the second valve 405 to rotate, thereby opening the second valve 405. This ensures that the thermally runaway battery cluster 608 is located in the sealed space formed by the fireproof isolation box 601 and the fireproof plate 2 before the first valve 303 and the second valve 405 are opened. This can prevent the leakage of gas and water mist during subsequent fire extinguishing from affecting the normal battery cluster 608 and effectively reduce the economic losses caused by fire extinguishing.

[0037] Furthermore, after the smoke sensor 606 and temperature sensor 607 detect a fire, the controller simultaneously opens the solenoid valve 301 and the water pump 403. When the first valve 303 and the second valve 405 are opened, the heptafluoropropane in the heptafluoropropane storage tank 3 enters the gas nozzle 306 through the gas guide pipe 302 and the gas distribution plate 305, thereby achieving the gas extinguishing effect. At the same time, the water in the water tank 4 enters the water guide pipe 404 and the water distribution plate 407 through the water pump 403, and is then discharged. The water mist is sprayed from the nozzle 408, thereby achieving the fire extinguishing and cooling effect of water mist. Since the thermally runaway battery cluster 608 is located in the sealed space formed by the isolation fireproof box 601 and the fireproof plate 2, the concentration of heptafluoropropane in the sealed space will rise rapidly after the heptafluoropropane is sprayed out, ensuring the fire extinguishing effect and preventing the heptafluoropropane from overflowing and affecting other battery clusters 608. The water mist sprayed from the nozzle 408 will not splash outward and cause short circuits to other battery clusters 608, ensuring fire extinguishing safety.

[0038] The return water tank 5 is symmetrically fixed with guide rails 501 on the left and right, and the guide rails 501 are provided with return water inlets 502. The return water tank 5 is connected to the water storage tank 4 through the return water pipe 503.

[0039] During the water mist fire extinguishing process, the dripping water droplets can enter the return water tank 5 through the drain outlet 603 and the return water pipe 503, and then flow back into the water storage tank 4 through the return water pipe 503, thereby realizing the recycling of water and avoiding water waste.

[0040] In summary, this application employs an isolation-type fire extinguishing mechanism, which can isolate and extinguish a single thermally runaway battery cluster 608 individually, effectively reducing the impact on other battery clusters 608 during the fire extinguishing process. Furthermore, the isolation-type fire extinguishing reduces the space for gas and water mist diffusion, allowing the gas and water mist to fill the sealed space more quickly, thus improving the fire extinguishing effect. In addition, due to the smaller isolation space, the amount of fire extinguishing gas and water used can be reduced, thereby reducing the fire extinguishing cost.
