Description

TECHNICAL FIELD

[0002] Under the background that the country is deeply promoting green low-carbon circular development as the core orientation, electric transportation tools (including electric bicycles and electric vehicles) are widely popularized due to the environmental protection and energy saving characteristics, and the construction scale of electric vehicle sheds is continuously expanded, but the fire safety hidden danger is increasingly highlighted. Electric vehicles are prone to fire during charging or parking due to reasons such as line aging and battery failure, and the fire spreads rapidly, which not only causes a large number of electric bicycles and electric vehicles to be damaged, but also may ignite surrounding building components, seriously threatening the safety of personnel and property, so the fire protection device of the electric vehicle shed becomes a key facility to guarantee public safety and meet the development concept.

[0003] According to the requirements of the fire safety specification, on the one hand, when the electric vehicle shed and the surrounding buildings or facilities exceed a certain safety distance, reliable fireproof partition facilities must be set up; on the other hand, for the electric vehicle parking scene, there is a mandatory requirement that every 12 electric vehicles need to set up a fireproof point. However, the existing related fireproof measures have many inconveniences and limitations: on the one hand, the existing electric vehicle shed fireproof partition self-sprinkling device has single function and redundant structure, and the core is around the fixed process of "automatic sensing-sprinkling partition", which needs to lay an independent water pipe and configure a special water tank, which not only increases the installation and construction cost, but also needs to continuously ensure the water pressure stability in the water pipe to ensure the sprinkling effect, and the subsequent maintenance process is complicated, and the exposed pipeline and water tank will damage the overall aesthetics of the electric vehicle shed; on the other hand, the existing partition facilities mostly use fireproof plates (fireproof walls are built in a masonry way), such fireproof plates are not only bulky and difficult to disassemble, but also have very low reusability, which are one-time use components and do not meet the low-carbon circular development requirements, and at the same time, the average heat insulation temperature of the commonly used fireproof plates on the market is 140 degrees Celsius, and the heat insulation performance is limited, which is difficult to adapt to the flexible protection needs in complex fire scenes.
