Detailed Implementation

[0016] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0017] This embodiment provides an automatic fire extinguishing system for electric bicycle charging and swapping cabinets. This fire extinguishing system can be precisely installed inside the swapping cabinet 100, meeting the fire protection requirements of the swapping cabinet 100. Compared with aerosol fire extinguishing systems, it can better extinguish fires inside the swapping cabinet 100, with better fire extinguishing effect. In addition, the fire extinguishing unit 20 of this utility model has a simple structure and small size, making it easy to install inside the swapping cabinet 100 without occupying a large amount of internal space.

[0018] Combination Figures 1 to 4 As shown, the automatic fire extinguishing system of this embodiment includes a container box 10, a fire extinguishing unit 20, and a drive pump group 30. The container box 10 is located outside the battery swapping cabinet 100 and stores fire extinguishing agent for supplying fire extinguishing agent. The fire extinguishing unit 20 is installed inside the battery swapping cabinet 100 to perform fire extinguishing treatment inside the battery swapping cabinet 100. In this embodiment, there are multiple fire extinguishing units 20, which correspond one-to-one with the battery swapping cabinet 100 to form a parallel structure. Thus, one container box 10 can provide fire protection for multiple battery swapping cabinets 100, which is more efficient and lower in cost.

[0019] In this embodiment, the fire extinguishing unit 20 is installed inside the battery swapping cabinet 100. The fire extinguishing unit 20 includes a connecting rod 21, a nozzle 22, and a heating element 23. The connecting rod 21 is fixedly installed inside the battery swapping cabinet 100, and a water spray pipe 211 is provided inside the connecting rod 21. The nozzle 22 is located at the end of the connecting rod 21, and a glass bulb 221 is provided on the nozzle 22 to seal the spray nozzle of the water spray pipe 211. The heating element 23 is fitted onto the surface of the glass bulb 221 to extinguish the fire. The glass ball 221 is heated, and the connecting rod 21 is installed inside the battery swapping cabinet 100 through the fixing plate 40. The fixing plate 40 is equipped with a temperature sensing cable 50 to monitor the temperature inside the battery swapping cabinet 100 in real time. When the temperature inside the battery swapping cabinet 100 reaches a predetermined value, the heating element 23 is activated to heat the glass ball 221, causing the glass ball 221 to heat up rapidly until it breaks. After the glass ball 221 breaks, the nozzle 22 sprays out the fire extinguishing agent to extinguish the fire inside the battery swapping cabinet 100.

[0020] Furthermore, the automatic fire extinguishing system of this embodiment also includes a control unit 60 located in the battery swapping cabinet 100 for overall control and information interaction. The heating element 23 is connected to the control unit 60 via a connecting cable 70. In this embodiment, the control unit 60 is a control panel with a power supply, which supplies power to the heating element 23. When the temperature inside the battery swapping cabinet 100 reaches a predetermined value, the control unit 60 controls the heating element 23 to start, and the heating element 23 heats the glass ball 221. The heating element 23 is controlled by the control unit 60. When the control unit 60 receives the temperature signal from the temperature sensing cable 50, the control unit 60 controls the heating element 23 to work, thereby heating the glass ball 221.

[0021] Combination Figure 1 , Figure 3 as well as Figure 4 As shown, in this embodiment, the water spray pipe 211 is connected to the water outlet pipe 32 through the three-way connector 80, so that the water outlet pipe 32 can be connected to multiple water spray pipes 211 at the same time to form a parallel structure, so that the container box 10 can supply water to multiple battery swapping cabinets 100. A piston 90 is provided at the end of the water spray pipe 211 near the glass ball 221. When the glass ball 221 bursts, the piston 90 pushes the extinguishing agent into the nozzle 22, and the extinguishing agent is sprayed out through the nozzle 22.

[0022] In this embodiment, the nozzle 22 is provided with a plurality of nozzles 222, which are evenly distributed on the surface of the nozzle 22 to spray out liquid. The evenly distributed nozzles 222 enable the extinguishing agent to be sprayed out from multiple angles, thereby improving the extinguishing effect.

[0023] Combination Figure 1 and Figure 2As shown, the drive pump set 30 of this embodiment is connected to an inlet pipe 31 and an outlet pipe 32. One end of the inlet pipe 31 is located inside the container box 10, and the outlet pipe 32 is connected to the spray pipe 211 to introduce the extinguishing agent into the spray pipe 211. Under the action of the drive pump set 30, the extinguishing agent located in the container box 10 is introduced into the spray pipe 211 through the outlet pipe 32 for subsequent fire fighting.

[0024] In this embodiment, the container 10 includes a box body 11 and a water bag 12. The water bag 12 is fitted inside the box body 11. A liquid level switch 121 is installed inside the water bag 12. The liquid level switch 121 can monitor the liquid level in the container 10 in real time. A flange cover plate 111 is provided on the box body 11. The flange cover plate 111 is provided with a liquid inlet for adding fire extinguishing agent.

[0025] In actual use, the automatic fire extinguishing system of this embodiment has multiple fire extinguishing units 20 installed in the battery swapping cabinet 100 in a one-to-one correspondence. The fire protection needs of multiple battery swapping cabinets 100 are met by a single container box 10. When the temperature inside the battery swapping cabinet 100 reaches a predetermined value, the heating element 23 heats the glass ball 221 until the glass ball 221 breaks, opening the water spray pipe 211 and spraying the extinguishing agent into the battery swapping cabinet 100 through the nozzle 22 for fire extinguishing.

[0026] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
