Description

Technical Field

[0001] This utility model relates to the field of energy storage equipment safety technology, specifically to an air inlet and outlet structure for an energy storage room. Background Technology

[0002] The rapid development of the new energy industry has led to the widespread application of electrochemical energy storage systems (such as lithium battery energy storage). Energy storage batteries continuously generate heat during operation. Poor ventilation and heat dissipation can easily cause overheating, affecting lifespan and even leading to safety accidents. More seriously, when a battery experiences thermal runaway, it releases large amounts of flammable gases (such as hydrogen and carbon monoxide) and toxic gases. When these gases accumulate to a certain concentration, they are highly susceptible to explosion upon contact with an open flame, posing an extremely high risk.

[0003] Traditional energy storage station ventilation fans lack sealing and cannot meet IP65 protection standards, allowing dust and rainwater to easily intrude and failing to isolate the internal and external environments. Utility Model Content

[0004] In view of the above-mentioned technical problems, the present invention provides an air inlet and outlet structure for an energy storage room.

[0005] To achieve the above objectives, this utility model provides the following technical solution: An air inlet and outlet structure for an energy storage chamber is provided, including an air inlet module and an air outlet module. Both include: a cover and a sealing door, both made of metal. The cover has an air passage that runs through the inside and outside, and a flexible rubber ring is provided at the outer end of the air passage. The sealing door is hinged to the cover via a pivot. An electric drive unit for driving the sealing door to rotate and open and close is provided inside the cover. When the sealing door is closed, it presses against the rubber ring to seal the air passage. When the sealing door is opened, it moves away from the rubber ring, allowing the air passage to connect inside and outside. The air intake module's duct is equipped with a filter layer that covers its air passage. The air outlet module is equipped with an outward-blowing fan inside its enclosure. The fan includes a support cylinder, an explosion-proof motor, and fan blades. The support cylinder is connected and fixed to the corresponding air duct. The explosion-proof motor is fixed to the support cylinder, and the fan blades are installed on the output shaft of the explosion-proof motor.

[0006] As a further optional solution, the periphery of the cover is provided with mounting flanges, and the mounting flanges have mounting holes.

[0007] As a further optional solution, the electric drive component is an electric linear actuator, the bottom of the electric linear actuator body is hinged to the cover, the rotating shaft is fixed with a transmission block, and the output end of the electric linear actuator is hinged to the transmission block.

[0008] As a further alternative, the rubber ring has a U-shaped cross-section, with its open side embedded in the outer end of the air duct.

[0009] As a further alternative, the inner side of the rubber ring is integrally formed with positioning fins, which are deformed to fit the air duct.

[0010] As a further alternative, the inner side of the rubber ring is integrally formed with an inner beam, and the two ends of the inner beam are connected to the two straight sides of the U-shape, so that the inner beam and the curved segment of the U-shape form a capsule.

[0011] As a further optional solution, the air intake module has a support mesh plate and a limiting mesh plate fixed to the air duct. The filter layer is a cotton layer, and the support mesh plate and the limiting mesh plate together clamp and fix the filter layer.

[0012] As a further alternative, the support mesh plate and the limiting mesh plate are detachably fixed together by bolt assembly.

[0013] The beneficial effects of this utility model are: This utility model discloses an air inlet and outlet structure for an energy storage chamber. During use, the air inlet and outlet modules are fixed to pre-drilled holes in the outer perimeter of the energy storage chamber. Under normal conditions, the sealed door is closed, isolating the air duct from the outside air, keeping the energy storage chamber sealed, preventing rainwater and dust intrusion, and meeting protection requirements. In the event of a fire, the fan can be activated in exhaust mode to quickly remove smoke, toxic and flammable gases, creating favorable conditions for firefighting and greatly reducing the risk of secondary explosions.

Detailed Implementation

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0026] This embodiment provides an air inlet / outlet structure for an energy storage chamber, including, as follows: Figures 1 to 5 The air intake module 100 shown and as shown Figures 6 to 9 The air outlet module 200 and air inlet module 100 shown have similar structures. The following describes the common structure included in both: It includes: a metal enclosure 1 and a sealing door 2. The enclosure 1 has mounting flanges 11 on its periphery, with mounting holes for sealing and fixing with the pre-reserved holes in the external energy storage chamber. The enclosure 1 has a through-duct 12 that connects the energy storage chamber to the outside. The outer end of the through-duct 12 has a flexible rubber ring 3.

[0027] The sealing door 2 is hinged to the housing 1 via a pivot 4. An electric drive unit is located inside the housing 1 to rotate and open / close the sealing door 2. When the sealing door 2 closes, it presses against the rubber ring 3, sealing the ventilation duct 12. When the sealing door 2 opens, it moves away from the rubber ring 3, allowing the ventilation duct 12 to connect internally and externally. This ensures that the sealing door 2 is normally closed, isolating the ventilation duct 12 from outside air, keeping the energy storage chamber sealed, and preventing rainwater and dust intrusion, thus meeting protection requirements. In the event of a fire, the exhaust fan 8 can be activated to quickly expel smoke, toxic and flammable gases, creating favorable conditions for firefighting and greatly reducing the risk of secondary explosions.

[0028] In this embodiment, the electric drive component is an electric linear actuator 5. The bottom of the electric linear actuator 5 is hinged to the cover 1. The rotating shaft 4 is fixed to a transmission block 41 by screws, and the output end of the electric linear actuator 5 is hinged to the transmission block 41. In this way, both ends of the electric linear actuator 5 are movably connected, and when it drives the rotating shaft 4 to rotate, it will also have a certain amount of oscillation, thus avoiding interference between parts.

[0029] In this embodiment, the cross-section of the rubber ring 3 is U-shaped, with its open side embedded in the outer end of the air duct 12. A positioning fin 31 is integrally formed on the inner side of the rubber ring 3. The positioning fin 31 deforms to press against the air duct 12, strengthening the clamping and limiting between the rubber ring 3 and the air duct 12. An inner beam 32 is integrally formed on the inner side of the rubber ring 3. The two ends of the inner beam 32 connect to the two straight sides of the U-shape, thereby forming a bladder with the curved segment of the U-shape, which is then compressed and deformed by the sealing door 2 for sealing.

[0030] It is understandable that the common structure of the air intake module 100 and the air outlet module 200 refers only to the fact that they have the same function and connection method, but their size and shape may differ.

[0031] The main differences between the air intake module 100 and the air outlet module 200 are: In this embodiment, the air intake module 100 has an air duct 12 with a filter layer 6 covering its air passage. The air intake module 100's air duct 12 is fixed with a support mesh plate 7 and a limiting mesh plate 71. The filter layer 6 is a cotton layer, and the support mesh plate 7 and the limiting mesh plate 71 together clamp and fix the filter layer 6. The support mesh plate 7 and the limiting mesh plate 71 are detachably fixed together by a bolt assembly, allowing for easy removal to clean dust and catkins.

[0032] In this embodiment, the air outlet module 200 has an outward blowing fan 8 inside the cover 1. The fan 8 includes a support cylinder 81, an explosion-proof motor 82, and a fan blade 83. The support cylinder 81 is connected and fixed to the corresponding air duct 12. The purchased explosion-proof motor 82 is fixed to the support cylinder 81, and the aluminum alloy fan blade 83 is installed on the output shaft of the explosion-proof motor 82.

[0033] Furthermore, as a further improvement, traditional air intake and exhaust structures typically have a single function, only providing simple fan start / stop ventilation, and cannot effectively sense the environmental conditions inside the chamber. They usually operate independently of the fire protection system and lack linkage. This design can be further improved by incorporating an electronic control module 9 within the enclosure 1, which can communicate with sensors, including temperature sensors, smoke sensors, and combustible gas sensors, and link with the energy storage system's central control platform and the fire protection system through the communication module.

[0034] Under normal operating conditions, the electronic control module 9 automatically controls the start, stop, and speed of the fan 8 according to a preset program and sensor data. For example, when the temperature sensor detects that the temperature inside the cabin is too high, it automatically opens the sealed door 2 and starts the fan 8 to cool down; when the combustible gas sensor detects that the gas concentration has reached the lower explosive limit, it automatically starts the fan 8 to exhaust air and sends feedback to the central control unit, which then issues an alarm signal.

[0035] Integrated Functions, Intelligent Sensing: The built-in electronic control module 9 communicates with multiple sensors, enabling comprehensive real-time monitoring of the energy storage compartment's internal environment and providing early warnings of potential risks. Highly Efficient Linkage, Proactive Safety: Through communication with the central control system and deep integration with the fire suppression system, it automatically activates the highest-speed ventilation mode in the event of a fire, rapidly expelling smoke, toxic and flammable gases, creating favorable conditions for firefighting and significantly reducing the risk of secondary explosions.

[0036] It should be noted that this solution only provides the hardware structure. The electronic control module 9, sensors, etc., are existing technologies, which are implemented by constructing computer software functional modules to control the start and stop of the fan 8 and the opening and closing of the sealing door 2. This solution merely integrates this existing technology into the air inlet and outlet structure of the energy storage room and does not constitute any obstacle for those skilled in the art to implement this solution. Of course, the air inlet and outlet structure hardware structure provided in this solution can also be used to manually operate and control the start and stop of the fan 8 and the opening and closing of the sealing door 2, and there are no restrictions on this.
