Description

Technical Field

[0001] The present invention relates to the technical field of intelligent charging piles, and in particular to an intelligent charging pile with a fire extinguishing and early warning function. Background Art

[0002] As the core facility for electric vehicle energy replenishment, charging piles play a similar role to traditional gas station refueling machines, but are more environmentally friendly and adaptable. They are cleverly designed to be fixed on the ground or installed on the wall, and are widely deployed in various public places such as public buildings, bustling shopping malls, large public parking lots, and parking lots or dedicated charging stations in residential areas. These charging piles can intelligently identify and adapt to electric vehicles of different voltage levels to meet diverse charging needs, greatly promoting the popularization and development of electric vehicles.

[0003] However, current charging piles still have some limitations in terms of safety protection, especially in terms of fire prevention and control. Most charging piles are fixedly installed on the ground and lack effective fire warning and immediate protection mechanisms. In the event of a fire, if a fire breaks out around the charging pile, due to the lack of an advanced early warning system, it is difficult to detect and respond to the fire in a timely manner, and it is impossible to take prompt measures to protect the charging pile from damage. At the same time, if the charging pile itself causes a fire due to internal failure or external factors, due to the current lack of automatic and efficient fire extinguishing methods, the fire may spread rapidly, threatening not only the safety of the charging pile itself, but also the adjacent charging facilities, causing a wider range of safety hazards.

[0004] In order to solve these problems, it is necessary to comprehensively improve the fire warning and protection capabilities of charging piles. Summary of the invention

[0005] In order to solve the problems in the background technology, the present invention provides a smart charging pile with a fire extinguishing warning function. After detecting a smoke signal, the smart charging pile can automatically drive the charging pile body to fall into a concrete pit below the ground to form protection, and can also fill the concrete pit below the ground with carbon dioxide to form protection or achieve complete fire extinguishing.

Two rows of nozzles are installed at the bottom of the square tube 1011, and the outer row of nozzles is vertically downward, and the other row of nozzles on the inner side is inclined inward by 60° and is inclined downward. After a fire occurs, By opening the solenoid valve 1101 on the outlet pipe of the carbon dioxide cylinder 11, the carbon dioxide in the carbon dioxide cylinder 11 enters the square tube 1011 and is sprayed out along the nozzle, so as to prevent the flames from burning onto the charging pile body 1 after a fire occurs around the charging pile body 1, or to extinguish the fire after a fire occurs in the charging pile body 1, and to avoid safety hazards to other charging piles. When it is necessary to fill the carbon dioxide cylinder 11 with carbon dioxide, the solenoid valve on the inlet pipe of the carbon dioxide cylinder 11 can be opened by the remote control or the controller on the charging pile body 1, so as to inflate through the inflation pipe port 301 on the sealing baffle 3.

[0030] Specific usage and function of this embodiment: In the present invention, after a fire occurs around the charging pile body 1 or in itself, the smoke sensor 1012 detects a smoke signal and feeds the signal back to the controller inside the charging pile body 1, controls the driving motor 7 to drive the two sets of threaded rods 8 to rotate, and simultaneously opens the solenoid valve 1101 on the outlet pipe of the carbon dioxide gas cylinder 11. Driven by the two sets of threaded rods 8, the charging pile body 1 falls into a concrete pit below the ground, and the carbon dioxide in the carbon dioxide gas cylinder 11 enters the square tube 1011 and is sprayed out along the nozzle, so as to prevent the flames from burning onto the charging pile body 1 after a fire occurs around the charging pile body 1, or to extinguish the fire after a fire occurs in the charging pile body 1, so as to avoid potential safety hazards to other charging piles. After the charging pile body 1 falls into the concrete pit below the ground, the two sets of baffle frames 4 move toward each other under the action of the spring 1 502 and stick together to seal the square hole on the sealing baffle 3 to prevent the external flames from entering the concrete pit below the ground. At the same time, the carbon dioxide continuously sprayed from the nozzle fills the concrete pit below the ground, which can completely extinguish the fire after a fire occurs in the charging pile body 1 itself. When the charging pile body 1 needs to be raised from the concrete pit below the ground, the solenoid valve 1101 on the outlet pipe of the carbon dioxide gas cylinder 11 is closed by the remote control, and the two groups of baffle frames 4 are first pulled apart by the pull ring 401 on the baffle frame 4, and the hook rod is hooked between the pull ring 401 and the fixing ring 202, and then the driving motor 7 is controlled by the remote control to rotate in the opposite direction, driving the two groups of threaded rods 8 to rotate in the opposite direction, so that the charging pile body 1 is raised from the square hole on the sealing baffle 3; When the carbon dioxide cylinder 11 needs to be filled with carbon dioxide, the solenoid valve on the air inlet pipe of the carbon dioxide cylinder 11 can be opened by a remote control or a controller on the charging pile body 1, so that inflation is carried out through the inflation pipe port 301 on the sealing baffle 3.
