An automatic charging device and method with perfluorohexanone fire extinguishing function

Abstract

The invention discloses an automatic charging device and method with perfluorohexanone fire extinguishing function, which comprises a bottom plate and a charging frame arranged on the upper end thereof, the section of the charging frame is a U-shaped structure, and the charging frame and the bottom plate constitute two A closed structure with two ports, the inner wall of the charging frame is provided with a charging component, and the top of the charging frame is provided with a fire extinguishing component, and the fire extinguishing component sprays perfluorohexanone to extinguish the fire; the fire extinguishing component and the charging component are connected with the processor. The control terminal is electrically connected. This application uses perfluorohexanone to replace the existing carbon dioxide, dry powder, sand and water, which can improve the fire extinguishing effect and reduce the damage to the equipment caused by fire extinguishing. Here, the perfluorohexanone sprays out When it is in liquid state, it can absorb a large amount of heat when it is vaporized, thereby playing the role of cooling down and extinguishing fire, ensuring the fire extinguishing effect.

[0002] With the development of science and technology, the development of electric vehicles has reached a white-hot stage. Electric bicycles and electric vehicles are popular because of their low pollution and low cost. The number of buyers is increasing. Their charging equipment is an important demand for electric vehicles, so there are public ones. Charging stations, automatic charging stations are set up in outdoor public areas or underground garages, which are convenient for electric vehicles to charge and last. However, traditional charging stations are not equipped with safety devices. During the charging process, fires are prone to occur, and failure to detect them in time may even cause the charging equipment to explode. At the same time, it will cause a fire in the nearby charging equipment or surrounding objects, and even cause a fire in an area, which will increase economic losses.

[0003] In response to this problem, the existing patent notification number is CN110450670B, which discloses a charging device for automatic fire extinguishing. The device extinguishes the fire by injecting carbon dioxide in the horizontal direction, and increases the spray range by making the fire extinguishing nozzle move back and forth. However, the carbon dioxide fire extinguishing The fire extinguishing effect is not good for the following reasons:

[0004] 1. Carbon dioxide itself is gaseous, so the way it can extinguish fire is to use it to cover the surface of the burning material and to be at a lower temperature when it is gasified inside the tank, but in fact the density of carbon dioxide is almost the same as that of air, and this The gasified carbon dioxide in this application can absorb very little heat, so the fire extinguishing effect is not obvious due to the two reasons;

[0005] 2. The fire extinguishing method adopts the method of horizontal spraying. Since this method of fire extinguishing needs to cover a large area of ​​the burning material, this method of spraying only on one side of the winding will result in a large fire extinguishing dead angle and poor fire extinguishing effect. The position movement is limited, so the actual fire extinguishing effect is not obvious

[0006] And the patent notification number is that the fire extinguishing mode of CN111114366B adopts water to extinguish the fire, and the side effect after the fire extinguishing is comparatively huge, impractical
