Technical Field
[0001] This application relates to an automatic descent firebreak for vehicles, and more particularly to the field of fire extinguishing technology for new energy vehicles. Background Technology
[0002] New energy vehicle batteries pose a risk of spontaneous combustion. This combustion is a chemical reaction, and due to limitations such as garage ceiling height, fire trucks and firefighters often struggle to access the scene. Consequently, such fires frequently go uncontrolled in their early stages, leading to significant property damage and even endangering lives. To avoid major hazards from spontaneous combustion of new energy vehicle batteries, the focus should be on self-rescue in underground garages and villa garages, with efforts made to control and extinguish the fire in its initial stages to ensure effective containment.

[0029] Please refer to the instruction manual appendix. Figure 1 To be continued Figure 4 As shown, this utility model is an automatic slow-descent firebreak for vehicles, including a housing 1. The housing 1 adopts a fireproof cable tray used in underground parking garage projects. The housing 1 is installed directly above the space between two parking spaces. A roller 2 is installed inside the housing 1, and a fireproof cloth 3 is wound around the roller 2. The fireproof cloth 3 is fiberglass wall covering. A counterweight 31 is provided below the fiberglass wall covering. A rotation damper 4 is installed between the roller 2 and the housing 1. In this embodiment, the rotation damper 4 can be a unidirectional rotation damper 4 or a bidirectional rotation damper 4. A cover 5 is pivotally connected to the bottom of the housing 1. A limiter for opening the cover 5 is connected between the cover 5 and the housing 1. A hand crank 6 is also rotatably connected to the outside of the housing 1. The hand crank 6 is connected to the roller 2. After the cover 5 is opened by the limiter, the fireproof cloth 3 slowly slides down between the two parking spaces, thus preventing the spread of fire.
[0030] In this embodiment, the limiter includes a latch 7, which is installed at the bottom of the compartment cover 5. The latch 7 is controlled by an electromagnetic lock, allowing the compartment cover 5 to be opened remotely. The hand crank 6 is designed to be foldable, reducing the space required for transportation and installation. The hand crank 6 is not affected by the rotation damper 4 when rotating, making it convenient to store the fireproof cloth 3 after use.
[0031] The locking disc 81 is mounted on the roller 2. The locking tongue 82 moves in extension and retraction through the electromagnetic lock 83. The locking tongue 82 cooperates with the locking disc 81. When the locking tongue 82 is inserted into the locking disc 81, it restricts the movement of the roller 2. When the locking tongue 82 is disengaged from the locking disc 81, the roller 2 moves.
[0032] A smoke sensor 9 is installed on one side or above the housing 1. The smoke sensor 9 is connected to electromagnetic lock 1 and electromagnetic lock 2 83. The smoke sensor 9 can detect smoke signals and promptly open the compartment cover 5 via electromagnetic lock 1, and release the lock tongue 82 from the roller 2 via electromagnetic lock 2 83. Electromagnetic lock 1, electromagnetic lock 2 83 and smoke sensor 9 use a 12-24V low-voltage circuit, are battery powered, and do not require connection to a 220V power supply. The automatic slow-descent isolation firewall should be inspected annually, and the batteries should be replaced at the same time.
[0033] The working principle of this utility model's automatic descent isolation firewall is as follows:
[0034] First, the cover 1 is installed above the space between the two parking spaces via the boom 10. When a fire occurs in a vehicle, the smoke sensor 9 receives the fire signal and feeds it back to electromagnetic locks 1 and 2 83. Electromagnetic lock 1 controls the latch 7 to move, opening the cover 5. Electromagnetic lock 2 83 controls the latch 82 to pull out of the lock disc 81 and rotate the roller 2. The fireproof cloth 3 falls to the ground by its own weight plus the counterweight. The fireproof cloth 3 blocks the fire between the two vehicles, preventing the fire from spreading. When storing, turn the roller by cranking the handle to lift the cloth and counterweight, close the cover 5, and electromagnetic lock 1 locks the latch 7 of the cover 5. Electromagnetic lock 2 83 locks the roller 2. The automatic slow-descent fire barrier should be inspected annually and the battery should be replaced at the same time.
[0035] The above-described specific embodiments are merely preferred embodiments of this invention and are not intended to limit this invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this invention should be included within the protection scope of this invention.
