Description

Technical Field

[0001] This utility model relates to the technical field of fire protection devices for energy storage cabinets, specifically a multi-layer safety protection fire protection device for energy storage cabinets. Background Technology

[0002] An energy storage cabinet is the basic unit of an energy storage device. It stores energy by installing several lithium batteries. When in use, the energy is supplied by discharging the lithium batteries.

[0003] Lithium batteries generate heat during both energy storage and dissipation. However, the space inside the energy storage cabinet is small and has poor heat dissipation. When the lithium battery generates a lot of heat, it may bulge and explode or spontaneously combust, thus causing a fire.

[0004] To prevent fires, existing energy storage cabinets are often equipped with smoke or temperature sensors to detect the conditions inside the cabinet and control the sprinklers to extinguish the fire when a fire occurs.

[0005] However, it is difficult to suppress a fire by spraying water alone. When using water to extinguish a fire, the high temperature will cause the water to produce a large amount of water vapor, which cannot effectively cool the lithium battery.

[0006] It is evident that there is an urgent need for a multi-layered safety protection and fire-fighting device for energy storage to improve the safety of the energy storage cabinet. Utility Model Content

[0007] The purpose of this utility model is to provide a multi-layer energy storage safety protection fire protection device to solve the problems mentioned in the background art.

[0008] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a multi-layer safety protection fire protection device for energy storage, including an energy storage cabinet body, a multi-layer lithium battery bracket installed inside the energy storage cabinet body, the lithium battery bracket supporting lithium batteries, a water spray head installed inside the energy storage cabinet body, a perfluorohexanone spray head and a liquid cooling device also installed inside the energy storage cabinet body, and a liquid cooling circulation pipe connected to the liquid cooling device;

[0009] The water nozzle is connected to a water pump and a sensor, and the sensor is connected to the water pump.

[0010] The tail end of the perfluorohexanone nozzle is connected to a perfluorohexanone storage device, and the perfluorohexanone nozzle is connected to a sensor on the water nozzle. The perfluorohexanone nozzle is also connected to the lithium battery package.

[0011] The liquid cooling circulation pipe is arranged in a circular pattern around the lithium battery bracket and the lithium battery, and the liquid cooling circulation pipe is close to the lithium battery.

[0012] Preferably, the bottom of the energy storage cabinet body is provided with a base, a water tank is installed inside the base, and a water pump is installed inside the water tank.

[0013] Preferably, there are multiple water nozzles, and the multiple water nozzles are located on both sides of each layer of lithium battery bracket.

[0014] Preferably, there are multiple perfluorohexanone nozzles, which are equidistantly distributed between each layer of lithium battery support and close to the lithium battery.

[0015] Preferably, the liquid cooling device is installed on the right side of the energy storage cabinet body and isolated from the lithium battery, and the liquid cooling device is connected to the control device in the energy storage cabinet body.

[0016] Preferably, the liquid cooling device is equipped with a circulation pump to pressurize the liquid and circulate it inside the liquid cooling circulation pipe.

[0017] Preferably, the liquid cooling circulation pipes are distributed around the front, back, and periphery of each layer of lithium battery bracket, and the liquid cooling circulation pipes circulate through the outer protective shell of the lithium battery.

[0018] Preferably, the energy storage cabinet body is connected to a fire hydrant interface, which is a quick-connect connector.

[0019] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0020] First, this utility model installs a liquid cooling device inside the main body of the energy storage cabinet and connects a liquid cooling circulation pipe to the liquid cooling device. The liquid cooling circulation pipe surrounds the lithium battery bracket and the periphery of the lithium battery and is close to the lithium battery. Thus, during the use of the main body of the energy storage cabinet, the heat emitted by the lithium battery will be quickly dissipated through the liquid cooling circulation pipe and the cooling liquid flowing in the liquid cooling circulation pipe, avoiding the lithium battery from overheating and achieving the effect of preventing the lithium battery from spontaneously combusting due to high temperature.

[0021] Secondly, this utility model installs multiple perfluorohexanone nozzles inside the main body of the energy storage cabinet, distributing the perfluorohexanone nozzles between the lithium battery brackets and close to the lithium batteries. The controllers of the perfluorohexanone nozzles are connected to the sensing devices of the water nozzles. When a fire occurs, in addition to the water nozzles extinguishing the fire with water, the packaged perfluorohexanone sprayed by the perfluorohexanone nozzles can further enhance the fire extinguishing performance and reduce losses.

[0022] Third, this utility model directly connects a portion of the perfluorohexanone nozzle to the lithium battery casing, enabling direct fire extinguishing and cooling of the lithium battery in the event of a fire. Simultaneously, a fire hydrant interface is pre-installed on the main body of the energy storage cabinet, allowing for immersion fire extinguishing by injecting water through the fire hydrant interface when the fire is difficult to control, thus achieving rapid fire control.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1-4 A multi-layer safety protection and fire protection device for energy storage includes an energy storage cabinet body 1, a multi-layer lithium battery bracket 2 installed inside the energy storage cabinet body 1, a lithium battery bracket 2 supporting a lithium battery 3, a water spray head 4 installed inside the energy storage cabinet body 1, a perfluorohexanone spray head 5 and a liquid cooling device 6 installed inside the energy storage cabinet body 1, and a liquid cooling circulation pipe 7 connected to the liquid cooling device 6.

[0030] The water nozzle 4 is connected to a water pump and a sensor, with the sensor connected to the water pump;

[0031] The tail end of the perfluorohexanone nozzle 5 is connected to a perfluorohexanone storage device, and the perfluorohexanone nozzle 5 is connected to the sensor on the water nozzle 4. The perfluorohexanone nozzle 5 is also connected to the encapsulation of the lithium battery 3. When extinguishing a fire, it can directly extinguish the fire on the burning lithium battery 3, thereby improving the efficiency of fire extinguishing.

[0032] The liquid cooling circulation pipe 7 is arranged in a circular manner around the lithium battery bracket 2 and the lithium battery 3, and the liquid cooling circulation pipe 7 is close to the lithium battery 3.

[0033] Through the above technical solution, a liquid cooling device 6 is installed inside the main body 1 of the energy storage cabinet, and a liquid cooling circulation pipe 7 is connected to the liquid cooling device 6. The liquid cooling circulation pipe 7 surrounds the lithium battery bracket 2 and the lithium battery 3 and is close to the lithium battery 3. Thus, during the use of the main body 1 of the energy storage cabinet, the heat emitted by the lithium battery 3 will be quickly dissipated through the liquid cooling circulation pipe 7 and the cooling liquid flowing in the liquid cooling circulation pipe 7, avoiding the high temperature of the lithium battery 3 and achieving the effect of preventing the lithium battery 3 from spontaneously combusting at high temperature. The circulating coolant will accelerate the heat conduction on the outer surface and surrounding area of ​​the lithium battery, thereby accelerating the heat loss and achieving the heat dissipation effect. The heat dissipation through liquid cooling will inevitably require the configuration of related equipment, such as a pump body for circulation and a liquid storage device for heat dissipation, to form a heat circulation. The internal heat dissipation technology is an existing technology. It is only necessary to seal the lithium battery package and set a sandwich or gap. The perfluorohexanone nozzle is completely sealed in the sandwich or gap and does not need to contact the internal cells of the lithium battery, so it will not affect the use of the lithium battery.

[0034] Multiple perfluorohexanone nozzles 5 are installed inside the main body 1 of the energy storage cabinet, and the perfluorohexanone nozzles 5 are distributed between the lithium battery brackets 2 and close to the lithium batteries 3. The controller of the perfluorohexanone nozzle 5 is connected to the sensing device of the water nozzle 4. When a fire occurs, in addition to the water nozzle 4 extinguishing the fire with water, the package-grade perfluorohexanone sprayed by the perfluorohexanone nozzle 5 can further improve the fire extinguishing performance and reduce losses.

[0035] Specifically, the bottom of the main body 1 of the energy storage cabinet is equipped with a base, and a water tank is installed inside the base, with a water pump installed inside the water tank.

[0036] Through the above technical solution, a water tank and a water pump are installed in the base of the main body 1 of the energy storage cabinet. In the event of a fire, the water pump can quickly draw liquid for fire extinguishing, reducing the length of the pipeline and increasing the water supply speed. Under normal circumstances, the water tank in the base of the main body 1 of the energy storage cabinet can be used as a configuration to improve the stability of the energy storage cabinet.

[0037] Specifically, there are multiple water nozzles 4, which are located on both sides of each layer of lithium battery bracket 2.

[0038] By using the above technical solution, multiple water nozzles 4 are set up so that the water nozzles 4 can completely cover the periphery of the lithium battery 3. When a fire occurs, the fire can be extinguished without any blind spots. In addition, multiple water nozzles 4 can increase the water volume, thereby extinguishing the fire as quickly as possible.

[0039] Specifically, there are multiple perfluorohexanone nozzles 5, which are equidistantly distributed between each layer of lithium battery bracket 2 and close to the lithium battery 3.

[0040] Through the above technical solution, multiple perfluorohexanone nozzles 5 are set up to be used in conjunction with water nozzles 4. In the event of a fire, the water nozzles 4 and perfluorohexanone nozzles 5 spray the lithium battery 3 alternately. Moreover, when extinguishing a fire, the perfluorohexanone nozzles 5 can cool down the lithium battery 3 faster than water, thereby suppressing reignition through cooling.

[0041] Specifically, the liquid cooling device 6 is installed on the right side of the energy storage cabinet body 1 and is isolated from the lithium battery 3. The liquid cooling device 6 is connected to the control equipment in the energy storage cabinet body 1.

[0042] By using the above technical solution, the liquid cooling device 6 is isolated from the lithium battery 3, thereby effectively preventing the heat generated by the liquid cooling device 6 during operation from affecting the lithium battery 3. It also facilitates the connection and power supply of the liquid cooling device 6 to the electrical components in the main body of the energy storage cabinet 1. When setting the working mode of the liquid cooling device 6, the operator can stay away from the lithium battery 3 and the electrode connector of the lithium battery 3, thus improving safety.

[0043] Specifically, the liquid cooling device 6 is equipped with a circulation pump that pressurizes the liquid and causes it to circulate inside the liquid cooling circulation pipe 7.

[0044] Through the above technical solution, the circulation pump inside the liquid cooling device 6 is used to pressurize the condensate, so that the condensate can circulate at high speed through the liquid cooling circulation pipe 7. The circulating condensate can control the temperature of the lithium battery 3 through contact with the lithium battery 3 through the liquid cooling circulation pipe 7, thereby reducing the possibility of spontaneous combustion of the lithium battery 3.

[0045] Specifically, the liquid cooling circulation pipe 7 is distributed around the front, back and periphery of each layer of lithium battery bracket 2, and the liquid cooling circulation pipe 7 circulates through the outer protective shell of the lithium battery 3.

[0046] Through the above technical solution, the liquid cooling circulation pipe 7 is arranged over a large area around the lithium battery bracket 2 and the lithium battery 3. This not only directly cools the lithium battery 3, but also increases the contact area between the liquid cooling circulation pipe 7 and the air, thereby cooling the air around the lithium battery 3.

[0047] Specifically, the main body 1 of the energy storage cabinet is connected to a fire hydrant interface, which is a quick-connect connector.

[0048] Through the above technical solution, a fire hydrant interface is set in the main body 1 of the energy storage cabinet. When the fire is difficult to control, the fire hydrant can be directly connected, so that water can directly submerge the interior of the main body 1 of the energy storage cabinet to achieve rapid fire extinguishing and prevent further expansion of losses.

[0049] During use, a liquid cooling device 6 is installed inside the main body 1 of the energy storage cabinet, and a liquid cooling circulation pipe 7 is connected to the liquid cooling device 6. The liquid cooling circulation pipe 7 surrounds the lithium battery bracket 2 and the lithium battery 3 and is close to the lithium battery 3. Thus, during the use of the main body 1 of the energy storage cabinet, the heat emitted by the lithium battery 3 will be quickly dissipated through the liquid cooling circulation pipe 7 and the cooling liquid flowing in the liquid cooling circulation pipe 7, so as to avoid the lithium battery 3 from overheating and achieve the effect of preventing the lithium battery 3 from overheating and spontaneous combustion.

[0050] By installing multiple perfluorohexanone nozzles 5 inside the main body 1 of the energy storage cabinet, and distributing the perfluorohexanone nozzles 5 between the lithium battery brackets 2 and close to the lithium batteries 3, and connecting the controller of the perfluorohexanone nozzles 5 to the sensing device of the water nozzles 4, when a fire occurs, in addition to the water nozzles 4 extinguishing the fire with water, the package-grade perfluorohexanone sprayed by the perfluorohexanone nozzles 5 can further enhance the fire extinguishing performance and reduce losses.

[0051] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
