Description

Technical Field

[0001] This invention relates to the field of fire extinguishing technology for industrial mobile equipment, and in particular to a fireproof charging compartment. Background Technology

[0002] Major fires caused by lithium batteries are occurring frequently, resulting in significant losses of life and property. Fires involving industrial mobile equipment (such as mobile carts, forklifts, or robots) during charging are sporadic and rapid; if not detected and effectively controlled in time, the fire can spread quickly, missing the optimal opportunity for extinguishing. Therefore, how to extinguish fires in industrial mobile equipment during charging in the first instance has become a major challenge.

[0003] Chinese patent CN201910820079.5 discloses a "fire-fighting charging cabinet," comprising a cabinet body, a main control box, a main controller housed within the main control box, charging sockets on the cabinet body, and a smoke detector. The cabinet body includes multiple single cabinets arranged sequentially, each single cabinet having at least two layers, with adjacent layers separated by partitions. The upper layer is used to house batteries, and a sand-falling fire extinguishing device is installed above the batteries. When the smoke detector detects that the smoke concentration inside a single cabinet exceeds a threshold, it triggers a smoke alarm and transmits the information to the main controller. The main controller then activates the sand-falling fire extinguishing device, which automatically falls sand to cover the batteries below. When a battery catches fire, the sand-falling fire extinguishing device automatically activates under the control of the fire-fighting charging cabinet, dumping the sand stored within it to cover the batteries below, effectively isolating them from the air and extinguishing the fire.

[0004] However, this patent is for a small charging cabinet, which is only suitable for charging individual batteries and cannot provide fire protection when charging industrial mobile equipment in situ. Summary of the Invention

[0020] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0021] Please see Figures 1 to 2 , Figure 1 A schematic diagram of the structure of the charging fireproof compartment provided by the present invention; Figure 2A top view of the charging fireproof compartment provided by the present invention.

[0022] The fireproof charging compartment provided in this embodiment of the invention includes a charging chamber for accommodating industrial mobile equipment. A socket 3 and a fire monitoring device are installed inside the charging chamber. The fireproof charging compartment includes two rows of parallel box assemblies 1. One side of the two rows of box assemblies 1 is connected by a rear side panel 2, and the other side is provided with an openable door 4. The box assemblies 1, the rear side panel 2, and the door 4 enclose the charging chamber. A storage cavity 1.1 for storing solid fire extinguishing materials is provided inside the box assembly 1. A discharge port is provided on the side of the storage cavity 1.1 facing the charging chamber, and an openable discharge door 1.2 is provided at the discharge port. A controller 7, a first drive mechanism for driving the door 4, and a second drive mechanism for driving the discharge door 1.2 are provided inside the box assembly 1. The fire monitoring device, the first drive mechanism, and the second drive mechanism are all communicatively connected to the controller 7.

[0023] Specifically, this invention employs two rows of parallel box-type components 1 fixedly connected to a rear side panel 2, forming a U-shaped charging chamber. An entrance / exit is formed on the other side of the box-type components 1, and the entrance / exit is opened and closed via a door 4. When the industrial mobile equipment enters the charging chamber for charging, the door 4 can be either open or closed. When the door 4 is open, it provides semi-enclosed protection for the industrial mobile equipment. In the event of a fire, the door 4 can be quickly closed to seal the charging chamber, releasing solid fire-retardant material to effectively prevent the spread of flames and smoke, thus avoiding the fire from spreading to surrounding equipment and the working environment, significantly improving the fire safety level of the charging operation.

[0024] Based on this, the box assembly 1 is equipped with a storage chamber 1.1 for storing solid fire extinguishing materials, and a discharge port and an openable discharge door 1.2 are opened on the side facing the charging chamber. After a fire is triggered, fire extinguishing materials can be directly and quickly put into the charging chamber to achieve full coverage suffocation fire extinguishing of the burning equipment. The fire extinguishing response is rapid and the action is direct. It can quickly suppress the fire in the early stage of thermal runaway of industrial mobile equipment and reduce the risk of explosion and secondary combustion.

[0025] Furthermore, the present invention can set the dimensions of the housing assembly 1 and the rear side panel 2 according to the specific type of industrial mobile equipment, so as to be compatible with various lengths, widths and heights of industrial mobile equipment such as mobile carts, mobile forklifts and mobile robots for in-situ charging without disassembling the battery. It has strong adaptability and is easy to use, meeting the integrated charging and protection needs of various types of equipment in industrial sites.

[0026] In summary, this invention, through controller 7, links and controls the fire monitoring device, the first drive mechanism, and the second drive mechanism to achieve fully automated control of the entire process, including fire detection, automatic closing of door 4, and automatic opening of unloading door 1.2, significantly improving the timeliness and reliability of fire response. Simultaneously, the opening and closing of door 4 and the unloading of solid fire extinguishing material are reliably transmitted and operate stably, adaptable to long-term continuous use in industrial settings. Furthermore, the solid fire extinguishing material is non-conductive and causes no secondary damage, significantly improving the safety of industrial mobile equipment and its electrical components, and enhancing the overall practicality of the charging fireproof chamber. Thus, the charging fireproof chamber provided by this invention enables fire protection for industrial mobile equipment while it is charging in situ, timely suppression of fire in the early stages of thermal runaway, reduction of the risk of explosion and secondary combustion, rapid fire extinguishing response, reliable effect, and improved charging safety for industrial mobile equipment.

[0027] Please refer to the following: Figure 3 , Figure 4 , Figure 6 and Figure 7 , Figure 3 A schematic diagram of the structure of the unit box in the charging fireproof compartment of the present invention, omitting the sealing plate; Figure 4 A side view of the unit housing of the charging fireproof compartment provided by the present invention; Figure 6 A schematic diagram of the drive housing of the charging fireproof compartment provided by the present invention; Figure 7 This is a schematic diagram of the rear structure of the drive housing of the charging fireproof compartment provided by the present invention, omitting the side sealing plate. In some embodiments, each row of housing components 1 includes a drive housing 1.4 and at least one unit housing 1.3. One side of the drive housing 1.4 is connected to a door 4, and the other side is connected to the unit housing 1.3. The unit housing 1.3 includes a frame 1.31 and a storage bin 1.32 connected to the frame 1.31. The storage bin 1.32 is provided with a discharge port. The unit housing 1.3 also includes a plurality of sealing plates 1.34, which are connected to the frame 1.31 and are disposed below the storage bin 1.32.

[0028] The housing assembly 1 of the present invention adopts a modular structure in which the drive housing 1.4 and the unit housing 1.3 are combined and spliced. That is to say, the number of unit housings 1.3 can be flexibly increased or decreased according to the size of the industrial mobile equipment, so as to achieve free adaptation of the charging space and improve versatility and expandability.

[0029] Specifically, the drive housing 1.4 serves as the carrier for the installation and control integration of door 4, combining the driving function of the unit housing with structural connection, aesthetic decoration, and functional integration. The unit housing 1.3 adopts a split structure of frame 1.31 and storage bin 1.32. Frame 1.31 improves the overall structural strength and installation accuracy, while storage bin 1.32 enables the storage and directional unloading of solid fire extinguishing materials. The storage chamber 1.1 is located inside storage bin 1.32, which is located above unit housing 1.3. Solid fire extinguishing materials possess natural falling potential energy, allowing them to flow quickly and smoothly from the unloading port under gravity during a fire, without the need for additional pressurization. This ensures reliable operation and rapid response. Simultaneously, it provides ample space for charging operations below, accommodating in-situ charging of taller equipment such as mobile forklifts and mobile robots, significantly improving space utilization and equipment compatibility. In addition, a sealing plate 1.34 is installed below the storage bin 1.32, which can effectively seal the lower space of the unit box 1.3, prevent solid fire extinguishing materials from scattering, and make the solid fire extinguishing materials fall more effectively onto the industrial mobile equipment for fire extinguishing.

[0030] Please refer to it again. Figure 4 In some embodiments, the bottom plate 1.33 of the storage silo 1.32 is configured to slope downwards in the direction toward the discharge port.

[0031] Specifically, the bottom plate 1.33 of the storage silo 1.32 is inclined downwards along the direction towards the discharge port. This allows the solid fire extinguishing material to be automatically guided towards the discharge port under gravity and slide smoothly down, preventing the solid fire extinguishing material from accumulating, getting stuck, or remaining in the storage silo 1.32. This eliminates the need for additional pushing or stirring mechanisms, simplifying the overall transmission structure of the solid fire extinguishing material, reducing the risk of failure, and ensuring complete dispensing of the solid fire extinguishing material to fully cover industrial mobile equipment, thereby improving fire extinguishing effectiveness and operational stability.

[0032] Please refer to it again. Figure 5 In some embodiments, the first drive mechanism includes a first motor 15, which is disposed inside the drive housing 1.4. The output end of the first motor 15 is connected to one end of the crank connecting rod 16, and the other end of the crank connecting rod 16 is connected to the door 4.

[0033] Specifically, the first motor 15 is built into the drive housing 1.4. The sealing plate of the drive housing 1.4 effectively isolates it from external collisions or contaminants such as dust, improving the operational safety of the first motor 15. The rotational motion of the first motor 15 is then stably converted into the opening and closing motion of the door 4 through the crank connecting rod 16. The transmission is direct and the response is rapid. In conjunction with the controller 7 and the fire monitoring device, it realizes automatic door 4 closing in response to fire, quickly sealing the charging space in the early stage of a fire and blocking the path of fire spread.

[0034] Please refer to it again. Figure 3 , Figure 5 and Figure 6 In some embodiments, the charging fireproof compartment includes a second drive mechanism for driving the unloading gate 1.2. The second drive mechanism includes a second motor 12 and a transmission shaft 8. The second motor 12 is disposed inside the drive housing 1.4 and is electrically connected to the controller 7. The transmission shaft 8 is mounted on the unit housing 1.3 and is connected to the output shaft of the second motor 12. A gear 9 is mounted on the transmission shaft 8, and a rack 11 that meshes with the gear 9 is mounted on the unloading gate 1.2.

[0035] Specifically, the second motor 12 is built into the drive housing 1.4. The drive housing 1.4's sealing plate effectively isolates it from external collisions or contaminants such as dust, improving the operational safety of the second motor 12. The drive shaft 8 is connected to the output shaft of the second motor 12. Furthermore, the drive shaft 8 is connected to the output shaft of the second motor 12 via a coupling 23, ensuring stable power transmission to the unit housing 1.3. Simultaneously, the gear 9 meshes with the rack 11 to drive the unloading gate 1.2 to rise and fall, ensuring the unloading port opens quickly and completely, allowing solid fire extinguishing materials to fall promptly and cover the burning industrial mobile equipment. It can be seen that the second drive mechanism in this invention adopts mechanical meshing transmission, which has a simple structure, uniform force distribution, stable operation, and is less prone to jamming, making it suitable for long-term use in industrial environments.

[0036] Please see Figure 5 , Figure 5 The diagram shows the structure of the unloading door and the second drive mechanism in the charging fireproof compartment provided by the present invention; in some embodiments, the unloading door 1.2 is slidably connected to the unit box 1.3 through the sliding mechanism 10.

[0037] Specifically, the unloading gate 1.2 is mounted on the unit housing 1.3 in a vertically sloping manner via a sliding mechanism 10. Furthermore, the sliding mechanism 10 includes a sliding rail and a slider, with the rail connected to the unit housing 1.3 and the slider connected to the unloading gate 1.2. This creates a sliding connection between the unloading gate 1.2 and the unit housing 1.3, ensuring stable lifting and lowering of the unloading gate 1.2 along a set direction, significantly improving the reliability and response speed of its opening and closing. The sliding mechanism 10 employs a split rail and slider structure, effectively preventing problems such as wobbling or offset of the unloading gate 1.2, and ensuring that the gear 9 and rack 11 always maintain a stable meshing state.

[0038] Please see Figure 8 , Figure 8 This is a schematic diagram of the transmission component connecting the second motor to the charging fireproof compartment provided by the present invention. In some embodiments, a reducer 17 is provided inside the drive housing 1.4, the input shaft 18 of the reducer is connected to the output shaft of the second motor 12, and the output shaft 20 of the reducer is connected to the transmission shaft 8.

[0039] Specifically, this invention reduces the output speed and increases the output torque by setting a reducer 17 between the second motor 12 and the transmission shaft 8, ensuring that the unloading gate 1.2 receives sufficient driving force and smoothly achieves the opening and closing process, avoiding drive failure due to excessive load. Furthermore, the reducer output shaft 20 is connected to the transmission shaft 8 via a coupling 23, which can compensate for installation errors and axial movement, ensuring continuous and stable power transmission.

[0040] In some embodiments, the reducer input shaft 18 extends outside the reducer 17 and is provided with a first bevel gear 19 at its end; the drive housing 1.4 is provided with a rotating shaft 22, and a second bevel gear 21 is provided at the end of the rotating shaft 22, and the first bevel gear 19 meshes with the second bevel gear 21.

[0041] Specifically, the reducer input shaft 18 extends outward and is equipped with a first bevel gear 19, which, together with the rotating shaft 22 and the second bevel gear 21 on the drive housing 1.4, forms a manual drive structure for emergency power outages. In the event of a sudden power outage or failure of the electrical control system due to a fire, the second drive mechanism cannot be started. However, by manually rotating the rotating shaft 22, power is transmitted through the second bevel gear 21 and the first bevel gear 19, forcibly driving the transmission shaft 8 and the unloading door 1.2 to open. This ensures that solid fire extinguishing material can still cover the industrial mobile equipment, significantly improving the reliability of emergency fire extinguishing. Thus, the charging fireproof compartment of this invention combines automatic drive with manual emergency response, providing strong redundancy protection capabilities and significantly improving overall safety and environmental adaptability, meeting the reliable fire extinguishing requirements under extreme conditions.

[0042] Please refer to it again. Figure 1 In some embodiments, each row of housing assembly 1 includes multiple unit housings 1.3, with adjacent unit housings 1.3 connected and adjacent drive shafts 8 connected by transmission.

[0043] Specifically, the present invention can also adopt a structure in which multiple unit boxes 1.3 are connected in series, with two adjacent unit boxes 1.3 connected and two adjacent drive shafts 8 connected by transmission. The connection method between two adjacent unit boxes 1.3 can be bolted, welded, or other connection methods. For example, the unit box 1.3 is provided with bolt holes 1.6, and two adjacent unit boxes 1.3 are detachably rigidly connected by bolts and bolt holes 1.6. Furthermore, the number of unit boxes 1.3 can be freely increased or decreased according to the size of industrial mobile equipment, flexibly expanding the charging space and greatly improving versatility and adaptability.

[0044] Meanwhile, adjacent drive shafts 8 are connected by coupling 23 to achieve coaxial transmission, ensuring continuous power transmission and good synchronization. This guarantees that multiple unloading gates 1.2 can open and close uniformly and unload synchronously, resulting in uniform fire extinguishing coverage and strong consistency of action.

[0045] Please refer to it again. Figure 3 and Figure 4 In some embodiments, the unit housing 1.3 is provided with multiple feet 1.5, which are connected to the ground; and / or, a smoke detector 6 is provided on the unit housing 1.3; and / or, a thermal imager 5 is provided on the rear side panel 2; and / or, a display screen 13 is installed on the drive housing 1.4; and / or, an alarm 14 is installed on the top of the drive housing 1.4; and / or, the unit housing 1.3 and the drive housing 1.4 have the same width; and / or, the unit housing 1.3 has a length of one meter; and / or, the housing assembly 1 is a fireproof housing, the rear side panel 2 is a fireproof board, and the door 4 is a fireproof door; and / or, the solid fire extinguishing material is at least one of sand, gravel, perlite, vitrified microspheres, fire sand extinguishing agent, and dry powder extinguishing agent.

[0046] Specifically, the 1.5 feet can be height-adjustable bolt-type feet to adapt to uneven ground; or fixed 1.5 feet can be used, directly anchored to the ground using expansion bolts or similar methods. This leveling of the charging fireproof compartment ensures structural stability, reliable alignment of transmission components, and effectively avoids problems such as jamming, abnormal noise, and uneven stress caused by uneven ground, significantly improving installation adaptability and on-site construction efficiency.

[0047] The unit enclosure 1.3 is equipped with smoke detectors 6, and the rear panel 2 houses a thermal imager 5, forming a dual-dimensional monitoring system of smoke concentration and temperature images. This system enables early fire prediction, precise location, and rapid response, significantly reducing false alarm and missed alarm rates. The smoke detectors 6 can be photoelectric, detecting the scattering or absorption of light by smoke particles to determine the fire situation; or they can be ionization smoke detectors, detecting changes in air ionization to determine the presence of smoke. The thermal imager 5 can be an uncooled infrared detector, offering advantages such as low cost and small size; or it can be a cooled infrared detector, providing higher sensitivity and measurement accuracy. Thus, the smoke sensors can quickly capture smoke generated in the early stages of a fire, enabling early detection and response. The thermal imaging camera provides visual images and temperature data over a wide area inside the charging fireproof compartment, quickly capturing the small-scale high temperatures generated in the early stages of a fire, assisting personnel in confirming the authenticity of the fire and reducing ineffective operations caused by false sensor triggers. The collaboration of multiple devices improves the accuracy and reliability of fire monitoring, ensuring that firefighting actions are only initiated when a real fire occurs.

[0048] The drive enclosure 1.4 integrates a display screen 13 and an alarm 14 to build a visual monitoring and sound and light linkage alarm system. It can display the equipment status, fire information and operating parameters in real time. In abnormal conditions, it can issue a high-intensity alarm at the same time to remind on-site personnel to evacuate quickly and take emergency measures, thereby improving the safety of use and the convenience of management.

[0049] The unit housing 1.3 and the drive housing 1.4 have the same width. In addition, the unit housing 1.3 adopts a standardized length design of 1 meter, realizing modular universal interchangeability of the entire series. It can be freely combined and spliced ​​according to the actual length of industrial mobile equipment such as mobile carts, forklifts, and robots, flexibly adapting to the needs of different operating scenarios. At the same time, it is convenient for mass production, warehousing and transportation and rapid on-site assembly, which greatly reduces manufacturing costs and installation difficulty.

[0050] The enclosure assembly 1, rear panel 2, and door 4 are all constructed from fire-resistant materials to form a fully enclosed fireproof isolation structure. This effectively blocks the spread of flames, isolates high-temperature conduction, and prevents the fire from spreading outwards, providing a safe buffer for internal firefighting and external rescue. For example, the materials for enclosure assembly 1, rear panel 2, and door 4 can be stainless steel, aluminum alloy, carbon steel, magnesium oxide fireproof board, rock wool sandwich panel, calcium silicate fireproof board, refractory ceramic board, refractory concrete, flame-retardant fiberglass, etc. Enclosure assembly 1, rear panel 2, and door 4 themselves possess excellent high-temperature resistance and flame-retardant properties, capable of withstanding the high temperatures of industrial mobile equipment charging fires without being ignited by the flames, effectively preventing the fire from spreading to the outside of enclosure assembly 1 and reducing the impact of the fire on the surrounding environment.

[0051] Solid fire extinguishing materials are selected from at least one of the following: sand, gravel, perlite, vitrified microspheres, fire sand extinguishing agent, and dry powder extinguishing agent. Fire sand extinguishing agent is mainly composed of base quartz sand or expanded perlite composite sand; dry powder extinguishing agent is made by grinding fine particles of baking soda, ammonium carbonate, ammonium phosphate, and other base materials with lubricants and moisture-proofing agents. These granular materials are widely available, inexpensive, and chemically stable, will not react secondary with the lithium batteries of industrial mobile equipment, leave no corrosive residue after extinguishing the fire, facilitate subsequent cleaning and equipment maintenance, and improve the adaptability of the fireproof compartment to different scenarios.

[0052] In summary, this invention discloses a charging fireproof chamber, which is formed by two rows of parallel box components 1, a rear side panel 2, and a door 4, providing in-situ charging space for industrial mobile equipment. Secondly, a controller 7, a first drive mechanism, and a second drive mechanism are integrated within the box component 1, and a storage cavity 1.1 for storing solid fire extinguishing materials is provided within the box component 1. When a fire is triggered, the controller 7 receives monitoring information from a fire monitoring device and simultaneously controls the first and second drive mechanisms to directly deliver solid fire extinguishing materials into the charging chamber. This achieves rapid coverage and extinguishing of the industrial mobile equipment, completing a fully automated fire extinguishing process including fire detection, automatic door closing 4, and automatic opening of the unloading door 1.2 for unloading, significantly improving the timeliness and reliability of fire emergency response. Furthermore, the solid fire extinguishing material is non-conductive and causes no secondary damage, significantly improving the safety of industrial mobile equipment and its electrical components, and enhancing the overall practicality of the charging fireproof chamber. Thus, the fireproof charging chamber provided by this invention can prevent fires while industrial mobile devices are charging in situ, suppress fires in the early stages of thermal runaway, reduce the risk of explosion and secondary combustion, and provide fast and reliable fire extinguishing response, thereby improving the charging safety of industrial mobile devices.

[0053] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0054] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
