Fire extinguishing system

Abstract

The invention provides a fire extinguishing system suitable for charging piles. The fire extinguishing system comprises the multiple charging piles arranged side by side, a mounting support, a fire extinguishing device and a camera shooting assembly; each charging pile is used for charging a corresponding vehicle; an upper support of the mounting support is suspended above the multiple charging piles; the fire extinguishing device is in sliding connection with the upper support and reciprocates along the upper support; the camera shooting assembly comprises a first camera shooting unit and a second camera shooting unit which are arranged on the two sides of the fire extinguishing device, and a first image taking area of the first camera shooting unit and a second image taking area of the second camera shooting unit are at least partially overlapped and form an image taking overlapping area; the fire extinguishing device comprises a fire extinguishing agent outlet, and the fire extinguishing agent outlet is located right above the image taking overlapping area. The fire extinguishing system has the advantages of high fire extinguishing efficiency and capability of realizing timely extinguishing and prevention of initial spreading of fire.

Description

technical field [0001] The invention belongs to the field of new energy vehicles, in particular to a fire extinguishing system suitable for charging piles. Background technique [0002] The electric vehicle charging pile is a device for "powering up" the battery. Using a high-efficiency charger, it can quickly charge electric vehicles, electric tricycles, and elderly scooters. [0003] The charging voltage of electric vehicle charging piles is relatively high, and the charging voltage of some large charging piles can reach 600-800 volts. Therefore, during the charging process of the vehicle, the charging pile is easy to generate heat and catch fire. How to provide a large number of charging piles with a safe, efficient, economical and environmentally friendly automatic device that can provide early warning and quickly extinguish fire has become an urgent problem to be solved. [0004] Most of the charging piles in existing residential areas are placed in underground or sem...

Problems solved by technology

Conventional self-sprinkler systems use temperature-sensitive nozzles, which are installed under the roof. When the nozzle reaches a certain temperature (normally 65 degrees), the nozzle will start to spray water to extinguish the fire, which causes the nozzle to operate later than the fire.

Due to the fast burning speed and high temperature of the battery when a fire occurs, coupled with the centralized placement of battery cars at the charging station, and the poor effect of pure water fire extinguishing agents on battery fires, the existing conventional self-spraying system is harmful to the fire at the battery car charging station. The prevention and eradication effect is not ideal
