Description

Technical Field

[0001] The invention belongs to the field of fire fighting and fire extinguishing, and specifically relates to an electric bicycle charging fire prevention device and a fire detection and fire extinguishing device. Background Art

[0002] Electric bicycles are currently very common, and for charging the power batteries inside, most communities now use centralized charging management equipment. A charging controller controls several charging sockets installed on a long mounting pole, and each charging socket corresponds to a charging parking space unit in front. Although the charging is managed on a timed basis, it is safer than charging by pulling wires individually without centralized charging management equipment, but the safety hazards have not been completely eliminated. This is mainly because when charging, each electric bicycle is placed in the charging parking unit, and then the respective chargers are connected to the charging power socket of the charging centralized management device and the charging socket on the electric bicycle for charging. Since the quality of the chargers of each vehicle is uneven and the quality of the batteries is also different, many people use inferior chargers and inferior batteries for cheapness, which can easily cause the power battery to overcharge. In mild cases, the power battery is damaged, and in severe cases, the power battery is overheated, causing thermal runaway short circuit and fire, causing fire. The key is that the number of electric bicycles using lithium batteries as power batteries is increasing. Lithium batteries are much more likely to catch fire than traditional lead-acid batteries, and once a fire occurs, it will explode. Since there is no effective isolation and timely control of the fire after the fire, the distance between each electric bicycle is small. Once a fire occurs in one vehicle, it will affect other vehicles. Once it burns, it will often cause a whole area, and even cause casualties and a large amount of property damage.

[0003] Therefore, it is imperative for us to technically solve the technical problems of electric bicycle fire easily affecting other vehicles, and timely detection and taking measures to effectively control and extinguish the fire after the electric bicycle catches fire. Summary of the Invention

The bottom of the winding spring fixing shaft is a section of screw A connected and fixed to the center of the fire blanket reel base. There is a slot A in the up and down direction from the head of the winding spring fixing shaft that can just fit into the spring piece at the tail of the winding spring. There is a Screw hole A is used to connect with the screw B at the bottom of the serial shaft of the clockwork spring fixing shaft. The head of the serial shaft of the clockwork spring fixing shaft has a screw hole B that can be used to connect with the screw A at the bottom of the clockwork spring fixing shaft. A clockwork spring is installed in each clockwork spring box. There are openings B in the upper and lower directions of the clockwork spring box, and the clockwork spring head can be extended. The clockwork spring head passes through the opening B horizontally and is connected to the tail end of the fire blanket. The clockwork spring head, the tail end of the fire blanket and the clockwork spring box are connected and fixed.

After installation, the fire blanket can be extended and retracted like a tape measure. When the fire blanket is pulled out, it becomes a rectangular fire blanket that can isolate fire.

[0008] Furthermore, connecting pieces A are provided on both sides of the bottom of the fire blanket roll cover, and there is an L-shaped metal baffle on each side of the bottom of the fire blanket roll cover.
