Description

Technical Field

[0001] This utility model relates to the field of storage cabinet technology, specifically to a mobile power storage cabinet with fire extinguishing alarm function. Background Technology

[0002] Portable power banks, such as those for electric vehicles, are typically stored in storage cabinets for long-term or temporary storage to prevent fire and theft. Using storage cabinets also allows for the centralized storage of multiple portable power banks, facilitating unified management and scheduling.

[0003] Physical damage to power banks during transport may cause internal short circuits or leaks, or short circuits inside or outside the battery may cause fires. When a power bank catches fire, firefighting is usually carried out by combining a fire detection mechanism with an automatic fire extinguisher.

[0004] However, this fire extinguishing method requires the detection agency to first detect the fire, then feed back to the control system, which then controls the fire extinguisher to spray extinguishing agent through pipelines. This method has a slow response time and takes a long time (each step from detection to extinguishing takes time, resulting in a long overall response time, and requires multiple steps such as detection, signal transmission, and control activation, which increases the extinguishing time). In addition, the area covered by the fire source is relatively small, which may affect and damage other mobile power supplies in the storage cabinet, resulting in significant economic losses. Summary of the Invention

[0005] In view of this, the purpose of this utility model is to provide a portable power bank storage cabinet with fire extinguishing alarm function, so as to solve the technical problems of the existing portable power bank storage cabinets having a slow response speed, long time consumption, and small coverage area of ​​the fire source, which easily leads to the damage of other portable power banks in the storage cabinet.

[0006] This utility model is achieved through the following technical solution:

[0007] A portable power bank storage cabinet with fire alarm function includes a cabinet body with several independent accommodating cavities for storing portable power banks. A fire extinguisher A is installed on the top of the cabinet body. A fire extinguishing pipe is connected to the fire extinguisher A. Several nozzles are installed on the fire extinguishing pipe. The output end of the nozzles is connected to the accommodating cavity.

[0008] Each of the aforementioned cavities is equipped with a fire extinguisher B and a detection component for detecting whether a fire has occurred in the cavity.

[0009] Furthermore, the cabinet includes an outer cabinet and a partition with vertical separation inside the cabinet, with inner cabinets installed on both sides of the partition;

[0010] The bottom of the inner cabinet is fixedly connected to the inner wall of the bottom of the outer cabinet, and a gap is left between the side of the inner cabinet, the inner wall of the outer cabinet, and the partition to form a wiring cavity, in which the fire extinguishing pipe is installed.

[0011] Furthermore, the inner cabinet includes an inner shell, and the inner shell is provided with multiple horizontal plates separated by transverse partitions.

[0012] A vertical plate is provided as a vertical partition in the space formed between the upper and lower horizontal plates and in the space enclosed by the horizontal plates and the inner wall of the inner shell. The vertical plate and the horizontal plate together with the inner wall of the inner shell form the receiving cavity.

[0013] Furthermore, the detection component includes a smoke sensor and a temperature sensor fixed to the side wall of the receiving cavity.

[0014] Furthermore, the fire extinguishing pipe includes a main pipe connected to the fire extinguisher A, a number of branch pipes are provided on the main pipe, the nozzle is installed on the branch pipe, and each branch pipe is equipped with a solenoid valve.

[0015] Furthermore, a top cabinet for installing the fire extinguisher A is fixedly connected to the top of the cabinet. A control panel is installed on the top cabinet, and an alarm is installed on the top cabinet.

[0016] The alarm, the smoke sensor, the temperature sensor, and the solenoid valve are all electrically connected to the control panel.

[0017] Furthermore, a sealing plate for closing the opening of the wiring cavity is installed between the outer cabinet and the inner cabinet; a cabinet door for closing the opening of the receiving cavity is hinged to the opening of the receiving cavity.

[0018] Furthermore, the inner surface of the inner cabinet is provided with a flame-retardant layer.

[0019] Furthermore, the rear side of the cabinet has several heat dissipation holes, which are connected to the receiving cavity.

[0020] 1. The fire extinguisher B is a self-destructing fire extinguisher. The rapid response of the fire extinguisher B enables it to automatically activate in the early stage of a fire, quickly release the extinguishing agent, and control the fire, providing valuable time for the subsequent fire extinguishing by the fire extinguisher A.

[0021] The fire extinguisher A is a conventional ejector fire extinguisher. The fire extinguisher A can further extinguish open flames based on the fire extinguisher B, ensuring that the fire is completely extinguished.

[0022] 2. The fire extinguisher B is usually installed on the top of the storage cabinet. When in use, it can cover the entire storage space to ensure that potential fire sources can be extinguished in time. Then, the fire extinguisher A is used to precisely extinguish specific fire sources. The combination of the two can cover a wider fire source area and improve the fire extinguishing effect.

[0023] 3. The dual fire suppression system can extinguish fires more quickly and effectively, reducing the damage to equipment and the environment, and lowering the cost of repair and recovery.

[0024] 4. By storing the power bank independently in one of the aforementioned accommodating cavities, the impact on nearby power banks can be reduced when the power bank catches fire. Furthermore, the power bank storage cabinet with fire extinguishing alarm function of this utility model can locate the accommodating cavity where the fire is located through the cooperation of the control panel and the detection component, achieving precise fire extinguishing. Moreover, it can extinguish fires in multiple accommodating cavities simultaneously, achieving comprehensive monitoring of the storage cabinet. Attached Figure Description

[0033] Please see Figure 1 and Figure 2 This utility model provides a technical solution: a portable power bank storage cabinet with fire extinguishing alarm function, comprising a cabinet body 1 having several independent accommodating cavities 2, wherein the accommodating cavities 2 are used to store portable power banks, and the opening of the accommodating cavity 2 is hinged with a cabinet door 16 for sealing the opening, thereby playing an isolation role to reduce the negative impact on nearby portable power banks after a portable power bank catches fire. The rear side of the cabinet body 1 has several heat dissipation holes 18, which are connected to the accommodating cavities 2 and dissipate heat through the heat dissipation holes 18 to avoid the temperature in the accommodating cavity 2 becoming too high, which could cause a short circuit in the portable power bank.

[0034] Please see Figures 1 to 3 The top of the cabinet 1 is fixedly connected to a top cabinet 8, a control panel 9 is installed on the top cabinet 8, and an alarm 10 is installed on the top cabinet 8. The alarm 10 is used to issue an alarm to remind staff.

[0035] The top cabinet 8 is equipped with a fire extinguisher A3, which is a conventional spray-type fire extinguisher. The fire extinguisher A3 is connected to a fire extinguishing pipe 4, which includes a main pipe 41 connected to the fire extinguisher A3. Several branch pipes 42 are provided on the main pipe 41, and each branch pipe 42 is equipped with a nozzle 5. The output end of the nozzle 5 is connected to the receiving cavity 2, and each branch pipe 42 is equipped with a solenoid valve 43.

[0036] The alarm 10, the smoke sensor 71, the temperature sensor 72, and the solenoid valve 43 are electrically connected to the control panel 9. The control panel 9, in conjunction with the temperature sensor 72, can also be used to display the temperature in each of the accommodating cavities 2. When the temperature exceeds a certain level, the temperature control system can be activated.

[0037] Please see Figure 2Each of the aforementioned accommodating chambers 2 is equipped with a fire extinguisher B6, which is a self-destructing fire extinguisher, and a detection component 7 for detecting whether a fire has occurred in the accommodating chamber 2. The detection component 7 includes a smoke sensor 71 and a temperature sensor 72 fixed to the side wall of the accommodating chamber 2. By detecting the temperature in the accommodating chamber 2 and whether smoke (fire phenomenon) is generated, it is determined whether a fire has occurred in the accommodating chamber 2. The detection end of the sensor is equipped with a protective cover (not shown). The protective cover is made of heat-resistant material and is breathable to ensure the normal operation of the sensor while reducing the negative impact on the sensor after the fire extinguisher is used.

[0038] Please see Figures 1 to 3 The cabinet 1 includes an outer cabinet 11 and a vertical partition 12 disposed inside the cabinet 1. The partition 12 is used to divide the interior of the cabinet 1 into different areas, which is conducive to the classified storage of different models of power banks. Inner cabinets 13 are installed on both sides of the partition 12. The inner cabinets 13 are used to store power banks. The inner surface of the inner cabinets 13 is provided with a flame-retardant layer 17. The flame-retardant layer 17 can prevent the transfer of heat and flame, and reduce the damage caused by fire.

[0039] The bottom of the inner cabinet 13 is fixedly connected to the bottom inner wall of the outer cabinet 11, and a gap is left between the side of the inner cabinet 13, the inner wall of the outer cabinet 11, and the partition 12 to form a wiring cavity 14. The fire extinguishing pipe 4 is installed in the wiring cavity 14. The wiring cavity 14 not only facilitates the arrangement of the fire extinguishing pipe 4, but also facilitates the heat dissipation of the mobile power supply. A sealing plate 15 is installed between the outer cabinet 11 and the inner cabinet 13 to seal the opening of the wiring cavity 14, so as to protect the pipes inside the wiring cavity 14.

[0040] Please see Figure 2 and Figure 3 The inner cabinet 13 includes an inner shell 131, and the inner shell 131 is provided with multiple horizontal plates 132 at horizontal intervals.

[0041] Vertical partitions 133 are provided in the space formed between the upper and lower horizontal plates 132 and in the space enclosed by the horizontal plates 132 and the inner wall of the inner shell 131. The vertical plates 133 and the horizontal plates 132 together with the inner wall of the inner shell 131 form the receiving cavity 2. The internal space of the inner shell 131 is divided into multiple independent receiving cavities 2 by the cooperation of several horizontal plates 132 and several vertical plates 133, which is conducive to the independent storage of the power bank. Furthermore, the inner surfaces of the horizontal plates 132 and the vertical plates 133 are provided with the flame-retardant layer 17 to reduce the damage to nearby power banks when the power bank catches fire.

[0042] The working principle of this utility model is as follows: When the mobile power supply in the storage cabinet catches fire, the fire extinguisher B6 quickly releases the extinguishing agent after detecting the fire signal (its specific activation mechanism is existing technology and will not be described in detail here). Since the fire extinguisher B6 is installed on the top of the receiving cavity 2, the fire extinguisher B6 sprays in all directions from the top, ensuring that the extinguishing agent can cover a large area, thereby effectively controlling the fire and extinguishing the fire.

[0043] Secondly, the environment in the containment cavity 2 is detected by the temperature sensor 72 and the smoke sensor 71. When a fire is detected in the containment cavity 2, the detection result is sent to the control panel 9. The control panel 9 controls the alarm 10 to sound an alarm and controls the corresponding solenoid valve 43 to open. At this time, the extinguishing agent in the fire extinguisher A3 is delivered to the nozzle 5 through the conduit and the branch pipe 42, and sprayed into the containment cavity 2 through the nozzle 5, thereby achieving rapid and continuous fire extinguishing and effectively reducing the damage caused by the fire to nearby mobile power supplies.

[0044] Finally, it should be noted that the above embodiments are only preferred embodiments of this utility model and should not be used to limit the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
