Description

Technical Field

[0001] This utility model relates to an electric vehicle charging device, specifically an electric bicycle charging shed with automatic air curtain fire extinguishing. Background Technology

[0002] Electric bicycles are vehicles that use batteries as auxiliary power and are based on ordinary bicycles, equipped with motors, controllers, batteries, throttles, brakes, and display systems. With breakthroughs in key technologies and continuous improvements in performance, electric bicycles have become a substitute for motorcycles and bicycles. Their speed, environmental friendliness, convenience, and affordability have also stimulated market demand. Currently, my country has over 300 million electric bicycles, making them a mainstay of short-distance urban travel. However, a shortage of charging infrastructure has led to difficulties for users in charging. Improper practices such as illegally connecting electrical wires and charging in stairwells pose serious safety hazards.

[0003] According to relevant data, there are currently only a few hundred thousand charging stations nationwide, far from meeting the needs of the huge number of electric bicycle users. Meanwhile, spontaneous combustion during electric bicycle charging is a pressing issue that endangers people's lives and property. Most electric bicycles currently use lithium-ion batteries as their energy storage components. Due to the operating characteristics of lithium-ion batteries, they are prone to thermal runaway during charging and discharging, leading to fires. Therefore, designing electric bicycle charging sheds with fire extinguishing functions is not only a safety measure but also a key technology for preventing the spread of fires and reducing loss of life and property.

[0015] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings.

[0016] This utility model discloses an electric bicycle charging shed with an automatic air curtain fire extinguishing system. It includes a gas cylinder, a manual shut-off valve, a temperature-controlled electric valve, an infrared temperature sensor, a cylinder, a piston, an exhaust port, a transmission rod, a conductive rod, a charging pile, a spring, a connecting rod, a blunt body, a nozzle, a parking space, and a charging shed. The gas cylinder is connected to the manual shut-off valve and the temperature-controlled electric valve. The temperature-controlled electric valve is connected to the infrared temperature sensor. The temperature-controlled electric valve is connected to the cylinder and the nozzle. The piston is located inside the cylinder and connected to the conductive rod via the transmission rod. AC power is connected to the charging pile through the conductive rod. The spring is connected to the connecting rod. A blunt body is located below the connecting rod. The blunt body and the airflow channel shell form the nozzle. The blunt body has a conical structure. The nozzle has a ring structure. The gas cylinder is a nitrogen cylinder.

[0017] The working process of this utility model:

[0018] When the electric bicycles stopped inside the greenhouse do not spontaneously combust, the manual shut-off valve in the device is open, the temperature control electric valve is closed, and the infrared temperature sensor detects a normal temperature signal; the piston is located on the left side of the cylinder, and the AC power supply is connected to the charging pile through the conductive rod; the spring pulls the connecting rod, and the nozzle is in a closed state.

[0019] When an electric bicycle spontaneously combusts, an infrared temperature sensor detects a high temperature signal, triggering the opening of the temperature-controlled electric valve. Nitrogen enters the cylinder, pushing the piston to the right. The transmission rod then disconnects the conductive rod from the AC power supply, cutting off power to the charging station. The nitrogen pushes a conical blunt body downwards, opening the nozzle to form a conical nitrogen curtain. This curtain covers the burning material and isolates it from the outside air, facilitating fire control. During an electric bicycle fire, the piston in the cylinder can drive the connecting rod to disconnect the conductive rod from the AC power supply, cutting off power to the charging station. The airflow through the conical blunt body forms a conical gas curtain, effectively covering the burning material and isolating it from the air. Nitrogen is non-flammable, providing even more effective fire retardancy. Its lower density than air allows it to quickly diffuse into the atmosphere, preventing prolonged accumulation in the charging station and facilitating firefighting efforts. After the electric bicycle fire subsides, the infrared temperature sensor detects a normal temperature signal, closing the temperature-controlled electric valve. The piston is manually reset, reconnecting the conductive rod to the AC power supply. The spring returns to its original position, closing the nozzle. The manual shut-off valve can be manually closed or opened as needed.

[0020] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
