Description

Technical Field

[0001] The present application relates to the technical field of carport fire protection, and in particular to a fire control device for a carport fire protection system of an electric vehicle. Background Art

[0002] With the popularity of electric bicycles, the risk of fire in centralized charging areas is increasing, so an efficient and intelligent fire alarm system is needed to prevent and respond to fire accidents in a timely manner. Existing electric vehicle shed charging facilities have problems such as uneven quality and lack of necessary safety protection measures, such as overcharging protection and overheating alarms. In addition, the planning and layout of the charging area is unreasonable, and there are insufficient fire isolation facilities. Once a fire occurs, the fire is easy to spread. In the face of a fire, an alarm reminder is required to respond to the fire in a timely manner.

[0003] In the prior art, when it comes to fire alarms in electric vehicle carports, the alarm device is usually fixed to the carport with bolts, which cannot be adjusted. After long-term use, it will become loose or fall off. During use, in order to reduce the impact of the heat generated by the alarm components on the alarm device, heat dissipation holes are opened in the metal box where the alarm components are installed to dissipate heat from the components. If a fire occurs, the fire or smoke in the carport will enter the box through the heat dissipation holes, affecting the components, making it impossible for the components to work, so that the alarm device cannot continue to give alarm reminders, and personnel cannot intervene in time, which can easily lead to the fire being out of control.

[0004] Therefore, it is necessary to provide a fire control device for an electric vehicle carport fire protection system to solve at least one of the above technical problems. Summary of the invention

[0005] In order to improve the problem that when a fire occurs in a carport, fire or smoke will enter the box through the heat dissipation holes, affecting the components, preventing the components from working and making the alarm device unable to continuously sound the alarm, the present application provides a fire control device for an electric vehicle carport fire protection system.
