[0023] Please refer to Figure 1 This utility model provides an explosion-proof charging chamber, comprising: a chamber body 10, wherein a charging component 11 is disposed within the chamber body 10; a detection component 12 and an alarm component 13, wherein the detection component 12 is disposed within the chamber body 10 to detect the real-time concentration of smoke within the chamber body 10, and the alarm component 13 is communicatively connected to the detection component 12; a spray component 14, wherein the spray component 14 is disposed within the chamber body 10, and the spray component 14 is communicatively connected to the detection component 12 so that when the real-time concentration detected by the detection component 12 exceeds a preset concentration, the alarm component 13 sounds an alarm, and the spray component 14 sprays fire extinguishing liquid; and a ventilation component 16, wherein the ventilation component 16 is disposed within the chamber body 10, and the ventilation port of the ventilation component 16 is connected to the inner cavity of the chamber body 10 so that the airflow in the inner cavity of the chamber body 10 flows to the outside through the ventilation component 16.

[0024] The explosion-proof charging chamber of this utility model includes a chamber body 10, a detection element 12, an alarm element 13, a liquid spraying element 14, and a ventilation element 16. The detection element 12 detects the real-time smoke concentration inside the chamber body 10. When the detected real-time concentration exceeds the preset concentration, the alarm element 13 sounds an alarm to promptly alert the user to the fire. The liquid spraying element 14 sprays fire extinguishing liquid to extinguish the flames in time, thereby promptly extinguishing the discovered fire and preventing the fire from spreading and causing an explosion. At the same time, the ventilation element 16 discharges the smoke and harmful gases in the inner cavity of the chamber body 10 to the outside, thus solving the problem that existing underground electric vehicle charging equipment cannot meet the explosion-proof requirements.

[0025] Optionally, the spraying component 14 is a nozzle.

[0026] In this embodiment, the explosion-proof charging compartment also includes a spray pipe 15, which is disposed above the compartment body 10. A spraying element 14 is disposed on the spray pipe 15, and the spray nozzle of the spraying element 14 is connected to the inner cavity of the spray pipe 15 so that the fire extinguishing liquid in the spray pipe 15 is sprayed into the compartment body 10 through the spraying element 14.

[0027] Specifically, the spray pipe 15 is used to connect the high-pressure water pipe and the spraying component 14, so that the fire extinguishing liquid can enter the spraying component 14 through the spray pipe 15 and be sprayed out, ensuring that the fire extinguishing liquid can be introduced into the chamber 10 from the outside, so as to ensure that the fire in the chamber 10 can be extinguished in time.

[0028] Furthermore, this layout ensures that the extinguishing liquid can evenly cover the entire interior of the chamber 10, improving fire extinguishing efficiency. It is particularly suitable for large charging facilities, such as bus charging stations, ensuring rapid fire control in emergencies. With this design, bus charging stations can quickly and evenly spray extinguishing liquid onto each charging station in the early stages of a fire, effectively controlling the fire and reducing property damage and casualties. Its application scenarios have been expanded to bus charging stations, electric truck charging areas, etc., ensuring the charging safety of large vehicles.

[0029] In this embodiment, there are multiple spray elements 14, and the multiple spray elements 14 are arranged at intervals on the spray pipe 15 along the extension direction of the spray pipe 15.

[0030] Specifically, multiple spray nozzles 14 ensure that the extinguishing liquid can evenly cover the entire inner cavity of the chamber 10, thereby improving the fire extinguishing efficiency of the explosion-proof charging chamber.

[0031] In this embodiment, there are multiple spray pipes 15, which are spaced apart above the tank body 10 along the width direction of the tank body 10.

[0032] Specifically, the multiple spray pipes 15 increase the number and distribution density of the spray nozzles 14, enabling the multiple spray nozzles 14 to spray the extinguishing liquid more quickly, expanding the spray range of the spray nozzles 14, and further ensuring that the extinguishing liquid can evenly cover the entire inner cavity of the chamber 10, thereby improving the fire extinguishing efficiency of the explosion-proof charging chamber.

[0033] Furthermore, this multi-spray nozzle (15-sprayer distribution) design further enhances the coverage and uniformity of the extinguishing liquid, making it particularly suitable for long, narrow charging bays, such as electric bicycle charging corridors, ensuring effective protection for each charging location. In electric bicycle charging corridors, this design ensures rapid and even coverage of the extinguishing liquid even over long distances, effectively preventing the spread of fire along the corridor and providing a safe environment for centralized charging of electric bicycles. Application scenarios include electric bicycle charging corridors and electric scooter charging areas, providing safe charging locations for personal electric mobility devices.

[0034] In this embodiment, the ventilation component 16 is a ventilation pipe, which is arranged at intervals along the width direction of the chamber 10 and the liquid spray pipe 15 on the top wall of the chamber 10. Multiple ventilation ports are provided at intervals on the circumferential side wall of the ventilation pipe; wherein, the extension direction of the ventilation pipe is parallel to the extension direction of the liquid spray pipe 15.

[0035] Specifically, this configuration allows the ventilation unit 16 to not only effectively expel smoke and harmful gases, but also to allow external gases to flow into the chamber 10 through the ventilation port, thereby promoting the diffusion of the extinguishing liquid.

[0036] Furthermore, this design not only effectively removes smoke and harmful gases but also promotes the diffusion of extinguishing liquid, making it suitable for any charging location requiring rapid ventilation and fire suppression, such as industrial equipment charging areas, thus improving overall safety. In industrial equipment charging areas, this design rapidly removes harmful gases generated during charging while simultaneously promoting the mixing of extinguishing liquid and air, enhancing fire suppression efficiency and providing reliable protection for the charging safety of industrial equipment. Application scenarios include industrial equipment charging areas and electric forklift charging warehouses, providing a safe charging environment for various industrial electric equipment.

[0037] In this embodiment, the explosion-proof charging compartment also includes a ventilation component, which is connected to a ventilation pipe. The ventilation component draws the airflow in the inner cavity of the compartment 10 to the outside through the ventilation pipe.

[0038] Specifically, the exhaust system can accelerate the discharge of harmful gases from the interior of the chamber 10, further reducing the risk of explosion of the chamber 10.

[0039] In addition, in the application of underground electric vehicle charging stations, exhaust components can quickly remove smoke and harmful gases generated during the charging process, reduce the risk of explosion, and ensure personnel safety. They are suitable for charging stations in underground parking lots and tunnels, providing safety assurance for charging facilities in enclosed environments.

[0040] Optionally, the exhaust component is an exhaust fan.

[0041] In this embodiment, the explosion-proof charging compartment also includes a camera 18, which is installed inside the compartment 10 to monitor real-time images inside the compartment 10.

[0042] Specifically, by using camera 18 to monitor real-time images inside the storage compartment 10, users can view and monitor the internal conditions of the storage compartment 10 in real time, promptly detect fire hazards, and it is suitable for unattended charging facilities.

[0043] Specifically, the explosion-proof charging compartment also includes an intelligent integrated explosion-proof panel 30. The detection element 12, camera element 18, alarm element 13, liquid spraying element 14 and ventilation element 16 are all connected to the intelligent integrated explosion-proof panel 30. Users can control the detection element 12, camera element 18, alarm element 13, liquid spraying element 14 and ventilation element 16 through the intelligent integrated explosion-proof panel 30.

[0044] Optionally, the detection component 12 is a smoke sensor, the camera component 18 is a camera, and the alarm component 13 is an alarm light.

[0045] In this embodiment, the explosion-proof charging compartment also includes a charging gun 19, a charging cable and a discharging cable 21. The charging gun 19 is electrically connected to the device to be charged, the charging cable is connected to both an external power source and the charging device 11, and the discharging cable 21 is electrically connected to both the charging gun 19 and the charging device 11.

[0046] Specifically, the charging gun 19 is electrically connected to the device to be charged, the charging cable is simultaneously connected to the external power source and the charging device 11, and the discharge cable 21 is simultaneously connected to the charging gun 19 and the charging device 11, so that a complete charging circuit is formed between the device to be charged, the charging device 11 and the external power source, ensuring that the current is smoothly delivered to the device to be charged.

[0047] Optionally, the device to be charged is an electric vehicle.

[0048] In this embodiment, the explosion-proof charging compartment also includes a protective tube 22, which is sleeved on the charging cable. Along the width direction of the compartment 10, the protective tube 22, the ventilation pipe and the liquid spray pipe 15 are spaced apart on the top wall of the compartment 10, and the extension direction of the protective tube 22 is parallel to the ventilation pipe.

[0049] Specifically, the use of the protective tube 22 further enhances the protection of the charging cable, making it suitable for charging facilities in harsh environments. It prevents external factors from damaging the charging cable. In electric vehicle charging stations near the sea or chemical plants, the protective tube can effectively prevent damage to the charging cable from salt spray corrosion and chemical erosion, extending the service life of the charging cable. It is suitable for charging facilities in harsh environments such as the sea, chemical plants, and ports, providing a guarantee for the charging safety of electric vehicles in special environments.

[0050] In this embodiment, the charging gun 19, the charging cable, and the discharging cable 21 are all made of flame-retardant materials.

[0051] Specifically, this design effectively prevents the fire from spreading through the charging gun 19, charging cable, and discharge cable 21 in the event of a fire, further ensuring the safety of the explosion-proof charging compartment.

The liquid spraying element 14 sprays fire extinguishing liquid to extinguish the flames in time, thereby promptly extinguishing the discovered fire and preventing the fire from spreading and causing an explosion. At the same time, the ventilation element 16 discharges the smoke and harmful gases in the inner cavity of the chamber body 10 to the outside, thus solving the problem that existing underground electric vehicle charging equipment cannot meet the explosion-proof requirements.
