Description

Technical Field

[0001] The utility model relates to the technical field of fire emergency isolation devices, in particular to an electric vehicle fire emergency isolation device. Background Art

[0002] Data shows that in 2023, a total of 21,000 electric bicycle fires were reported nationwide, an increase of 17.4% compared to 2022. It is urgent to reduce the hazards of electric bicycle fires. The hazards of electric vehicle fires are mainly manifested in high temperatures and thick smoke at the fire scene. Once a fire occurs, the thick smoke containing a large amount of toxic components such as carbon monoxide and hydrogen sulfide can cause poisoning and suffocation to death in a short period of time. Based on safety needs, the present invention has developed and implemented an electric vehicle fire emergency isolation device based on automatic sensing, which can effectively reduce the risk of poisoning and rapid spread of electric vehicle fires, and protect the lives and property of the people.

[0003] For example, the publication number CN212090579U is a fire-retardant box for charging batteries of electric vehicles, including a box body, which is connected to a closed body through a locking device, a temperature detection element is installed in the box body, a smoke detection element is installed on one side of the temperature detection element, the temperature detection element and the smoke detection element are connected to an audible and visual alarm through a wire, an independent power supply is provided below the audible and visual alarm, a charging conversion interface is installed on one side of the outer wall of the box body, the charging conversion interface is connected to a charging interface installed in the box body through a flame-retardant wire, a fire-resistant sealing material is provided at the contact part between the box body and the closed body, the box body and the closed body are joined by a nested structure, and are connected and fixed by a locking device.

[0004] After the inside and outside of the above-mentioned device are fully isolated, the internal oxygen content is insufficient to allow the battery to continue burning after a fire caused by a fault, and the "suffocation method" fire extinguishing effect can be achieved. When a battery fault causes a fire, it can isolate heat radiation, ensure the safety of personnel and prevent radiant heat from igniting surrounding combustibles. The box body and the closed body are connected by a nested structure when docking, which enhances the effect of preventing smoke from spreading from the inside of the fire-retardant box to the outside, thereby protecting the life and property of users. However, since most electric vehicles are charged directly at this stage, it is difficult to charge the battery alone. Most accidents nowadays are caused by the combustion of the entire electric vehicle, and the effect of isolating the battery alone is gradually reduced. Utility Model Content

[0005] The purpose of the utility model is to provide an electric vehicle fire emergency isolation device to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an emergency isolation device for an electric vehicle fire, comprising a lower end pad, a support frame is arranged around the lower end pad, and a fireproof cloth roof is arranged on the upper end surface of the support frame, and at the same time, hanging rods are arranged around the fireproof cloth roof, a fixed end is arranged in the center of the fireproof cloth roof, and a smoke treatment device is arranged in the middle of the fixed end, and at the same time, a flow port is arranged on the lower surface of the smoke treatment device, the rear side of the smoke treatment device is connected to an exhaust fan, and protective roller shutters are arranged at the lower ends around the fireproof cloth roof.

[0007] Preferably, transmission ends are placed on both sides of the upper surface of the fireproof cloth top, and the rear side of the transmission end is connected to the power transmission line, and the power transmission line is connected to the right plug board.

[0008] Preferably, a temperature-sensing fire detector is arranged at the lower end of the right transmission end, and a smoke-sensing fire detector is arranged at the lower side of the left transmission end.

[0009] Preferably, a metal structural frame is arranged around the fireproof cloth roof, and a rolling shutter bin is arranged at the lower end of the metal structural frame, and a movable column is arranged in the middle of the rolling shutter bin.

[0010] Preferably, a fireproof rolling shutter is arranged on the periphery of the movable column, and a magnet chain is placed at the lowest end of the fireproof rolling shutter.

[0011] Preferably, the other side of the transmission line is connected to a control box, and an audible and visual alarm is placed on the upper end of the control box.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. Compared with other electric vehicle fire emergency isolation devices, when a fire occurs, the alarm goes off and the roller shutter falls to prevent the fire from spreading (according to data, it usually takes only 30 seconds for an electric vehicle to go from smoking to catching fire. The system should be fast and timely from receiving the sensing signal to the roller shutter being in place, and it should be completed in place before the fire spreads to nearby vehicles or objects, forming a relatively closed environment, thereby effectively preventing the spread of smoke and fire). The fan works to attract thick smoke to the smoke treatment device located at the top of the device for filtration, and fresh air flows in from the bottom of the unsealed roller door to maintain air pressure balance.

[0014] 2. In addition, the device uses two analog buses to detect the signals of temperature and smoke detectors, and through intelligent judgment, it issues an alarm in a timely manner, and the modules on the bus control the opening and closing of the roller shutters and fans.
