Description

Electric bicycle charging shed capable of automatically extinguishing fire through air curtain Technical Field The utility model relates to an electric bicycle charging device, in particular to an electric bicycle charging shed capable of automatically extinguishing fire by an air curtain. Background The electric bicycle is a transportation means which uses a storage battery as an auxiliary energy source and is provided with a motor, a controller, a storage battery, a steering handle, a brake handle and other operating components and a display instrument system on the basis of a common bicycle. With the breakthrough of key technical aspects and the continuous improvement of the performance of the electric bicycle, the electric bicycle becomes a substitute product of the motorcycle and the bicycle, is quick, environment-friendly, convenient and cheap, and simultaneously stimulates the market appeal to the electric bicycle. At present, the electric bicycles in China have more than 3 hundred million, which becomes the dominant force of urban short-distance travel, but the shortage of charging facilities causes the problem of 'charging difficulty'. Irregular operations such as private wire drawing, corridor charging and the like cause serious potential safety hazards. According to the related data, the number of the charging piles in the national range is only hundreds of thousands, and the requirements of huge electric bicycle users can not be met. Meanwhile, the charging spontaneous combustion of the electric vehicle is an urgent problem to be solved, which endangers the life and property safety of people. At present, most electric bicycles adopt lithium ion batteries as energy storage components, and because of the working characteristics of the lithium ion batteries, the lithium ion batteries are easy to generate thermal runaway in the charge and discharge processes, so that fire disasters are caused. Therefore, the electric bicycle charging shed with the fire extinguishing function is designed, so that the electric bicycle charging shed is not only a safety measure, but also a key technology for preventing fire spreading and reducing personnel and property loss. Disclosure of Invention The utility model aims to provide an electric bicycle charging shed capable of automatically extinguishing fire by an air curtain, a piston in an air cylinder drives a connecting rod to separate a conducting rod from an alternating current power supply, when a fire disaster occurs, the charging pile is powered off instantaneously, and can cover the combustion objects with nitrogen and isolate air to control the fire. The utility model aims at realizing the following technical scheme: The electric bicycle charging shed comprises a gas cylinder, a manual stop valve, a temperature control electric valve, an infrared temperature sensor, a gas cylinder, a piston, an exhaust port, a transmission rod, a conducting rod, a charging pile, a spring, a connecting rod, a blunt body, a nozzle, a parking space and a charging shed, wherein the gas cylinder is connected with the manual stop valve and the temperature control electric valve, the temperature control electric valve is connected with the infrared temperature sensor, the temperature control electric valve is connected with the gas cylinder and the nozzle, the piston is arranged in the gas cylinder and is connected with the conducting rod through the transmission rod, an alternating current power supply is connected with the charging pile through the conducting rod, the spring is connected with the connecting rod, the blunt body is arranged below the connecting rod, and the blunt body and an air flow channel shell form the nozzle. The electric bicycle charging shed with the automatic fire extinguishing air curtain is characterized in that the blunt body is of a conical structure. The electric bicycle charging shed with the automatic fire extinguishing air curtain is characterized in that the nozzle is of an annular structure. The electric bicycle charging shed capable of automatically extinguishing fire by using the air curtain is characterized in that the air cylinder is a nitrogen cylinder. The utility model has the advantages and effects that: 1. the utility model is particularly suitable for preventing the situation of fire disaster caused by spontaneous combustion of the electric bicycle and has strong practicability. 2. The piston in the cylinder drives the connecting rod to separate the conducting rod from the alternating current power supply, so that the charging pile is powered off instantaneously when a fire disaster occurs, and nitrogen can cover the combustion objects and isolate air to control the fire.
