An electric vehicle charging pile with automatic control and fire extinguishing

Abstract

The utility model provides an electric vehicle charging pile with automatic control and fire extinguishing, which includes a charging pile body and a fire extinguisher. The charging pile body is connected with a charging plug, and a thermal protector is connected between the charging plug and the charging pile body; The switch is connected to the fire extinguishing switch through a wire rope. The fire extinguishing switch includes a fire-fighting temperature-sensitive glass ball and a shaft core in the casing. The bottom end of the shaft core is connected to a spring. The bracket, the two ends of the fire-fighting temperature-sensitive glass ball are respectively connected with the upper and lower brackets; the steel wire rope passes through the spring and is connected with the bottom end of the shaft core. The thermal protector is used to ensure that the charging pile body is disconnected when the instantaneous current increases or the temperature is high, so as to avoid burning out the electric vehicle due to high current and ensure the safe charging of the electric vehicle; in case of fire, the fire extinguishing switch will automatically turn on the fire extinguisher Put out the fire. It achieves double protection for the charging pile body and the electric vehicle being charged, and the effect is better.

Description

technical field [0001] The invention relates to an electric vehicle charging pile, in particular to an electric vehicle charging pile with automatic control and fire extinguishing. Background technique [0002] Electric vehicles are powered by vehicle-mounted power supplies and driven by motors to drive wheels. Because they have less impact on the environment than traditional vehicles, their prospects are widely optimistic. At present, China's electric vehicles have entered the stage of industrialization from the research and development stage. As of the end of March 2012, more than 19,000 energy-saving and new energy vehicles have been promoted in 25 demonstration cities. Among them, there are 16,800 vehicles in the public service field, 170 charging (replacing) power stations, more than 6,400 charging piles, and more than 9 billion passengers. [0003] However, the rate of fire caused by the charging pile heating is still high. To extinguish the fire with a fire extinguis...

Problems solved by technology

[0003] However, the rate of fire caused by the charging pile heating is still high. To extinguish the fire with a fire extinguisher, it is necessary to manually detect the fire, and to use the fire extinguisher manually, you first need to pull out the safety pin on the fire extinguisher, and then manually press the nozzle switch. Therefore, on the one hand, fire extinguishing Inconvenient, on the other hand, opening the cover of the charging pile increases air combustion, which is not easy to extinguish the fire
