Any two adjacent groups of unfolding sliders 38 are connected by two mutually hinged hinge rods 39, and a single hinge rod 39 is hinged between the unfolding slider 38 at the tail end position and the rotating disk 31.

[0035] The surface of the top plate 311 is provided with a fire extinguishing assembly 4, which includes a mixing box 41, a liquid medicine bucket 42, a blocking plate 43, a push-pull plate 44, a bidirectional screw 45, a worm gear 46, a blocking motor 47, a stirring motor 48, a stirring rod 49, a liquid discharge pipe 410 and an air outlet pipe 411;

[0036] A mixing box 41 is fixed to the surface of the top plate 311, and liquid medicine buckets 42 are fixed on both sides of the surface of the mixing box 41. A sealing plate 43 is slidably connected to the liquid outlet end of the liquid medicine bucket 42. A stirring motor 48 is screwed to the middle part of the surface of the mixing box 41, and a stirring rod 49 is fixed to the output end of the stirring motor 48. An air outlet pipe 411 is fixed to the top of the mixing box 41, and the bottom end of the air outlet pipe 411 passes through the surface of the top plate 311. Push-pull plates 44 are symmetrically fixed to the opposite sides of the two groups of sealing plates 43, and a bidirectional screw rod 45 is threadedly connected between the two groups of push-pull plates 44. The bidirectional screw rod 45 is rotatably connected to the surface of the mixing box 41 through a bearing frame, and a worm gear 46 is fixed to the middle part of the surface of the bidirectional screw rod 45, and a sealing motor 47 is coaxially fixed in the worm of the worm gear 46, and the sealing motor 47 is screwed to the surface of the mixing box 41, and a drain pipe 410 is fixed to the bottom end surface of the mixing box 41.

[0037] The present invention also provides a fire automatic protection intelligent charging pile and a method for using the same, comprising the following steps:

[0038] S1. When the smoke sensor 312 on the top plate 311 detects that the smoke concentration in the surrounding environment of the charging pile body 2 reaches a set threshold, it will immediately transmit a signal to the control system;

[0039] S2, then the control system will immediately start the isolation motor 33 to drive the swing hinge 37 to push the expansion slider 38 at the head end position to slide inside the rotating disk 31, and the adjacent expansion sliders 38 are linked in sequence through the hinge rod 39, so that the isolation roll cover 310 fixed between the expansion sliders 38 is expanded, and the charging pile body 2 is isolated and protected to prevent the fire from spreading;

[0040] S3. After the charging pile body 2 is isolated and protected, the blocking motor 47 is started and drives the two sets of blocking plates 43 to move relative to each other, thereby opening the liquid outlet of the liquid medicine hopper 42;

[0041] S4, the fire extinguishing liquid in the liquid medicine hopper 42 flows into the mixing box 41 to react and generate fire extinguishing gas, and at the same time, the stirring motor 48 starts and drives the stirring rod 49 to stir and mix the liquid medicine.

[0042] S5. The generated fire extinguishing gas will be transported to the fully expanded isolation roll cover 310 through the outlet pipe 411, and form a gas barrier around the charging pile body 2, so that a relatively safe oxygen-free or low-oxygen environment is created within a certain range around the charging pile body 2.

[0043] Working principle: When encountering a fire, the smoke sensor 312 on the top plate 311 monitors the smoke concentration of the environment around the charging pile body 2 in real time. Once the smoke concentration reaches a preset threshold, the smoke sensor 312 quickly transmits the detected signal to the control system installed inside it. The control system that receives the signal immediately starts the isolation motor 33 on the fixed frame 32 in the rotating disk 31. The isolation motor 33 drives the active gear 34 at the output end to rotate. The active gear 34 meshes with the driven gear 35, so that the rotating shaft 36 inside the driven gear 35 rotates in the fixed frame 32. The bottom end of the rotating shaft 36 is hinged to the expansion slider 38 at the head end position through a swing hinge 37. When the rotating shaft 36 rotates, it pushes the head end expansion slider 38 to slide inside the rotating disk 31. Due to any adjacent The two groups of unfolding sliders 38 are connected by two mutually hinged hinged rods 39. A single hinged rod 39 is hinged between the unfolding slider 38 at the tail end position and the rotating disk 31. When the slider at the head end moves, the remaining unfolding sliders 38 slide in turn through the linkage action of the hinged rod 39, so that the isolation roll cover 310 fixed between the two groups of unfolding sliders 38 is unfolded, so as to build a solid isolation and protection barrier between the charging pile body 2 and the flame, effectively blocking the direct invasion and spread of the flame, protecting the charging pile body 2 from the direct invasion of the flame, thereby ensuring the basic structural integrity and functionality of the charging pile body 2, reducing the direct damage of the fire to the charging pile body 2, reducing the cost and time investment of repairing or replacing equipment after the fire, and preventing the fire from spreading to the surrounding areas.

[0044] Furthermore, after the isolation roll cover 310 is unfolded, the blocking motor 47 on the surface of the mixing box 41 is started, and then the two-way screw 45 is driven to rotate on the surface of the mixing box 41 through the worm gear 46, thereby driving the two sets of push-pull plates 44 and the blocking plate 43 to move relative to each other, thereby opening the liquid outlet ends of the two sets of liquid medicine buckets 42, so that the fire extinguishing liquid in the two sets of liquid medicine buckets 42 flow into the mixing box 41 respectively, and at the same time, the stirring motor 48 in the middle of the surface of the mixing box 41 is started, driving the stirring rod 49 to stir and mix the inflowing fire extinguishing liquid, which significantly accelerates the reaction process of the liquid medicine, and promotes the reaction to be more sufficient and rapid by increasing the contact area and collision frequency between the reactants, thereby generating a large amount of fire extinguishing gas in a short time. The generated fire extinguishing gas is transported to the fully expanded isolation roll cover 310 through the outlet pipe 411 on the top of the mixing box 41, thereby filling the internal space of the isolation roll cover 310 in time, and creating an oxygen-free or low-oxygen environment around the charging pile body 2, rapidly reducing the oxygen concentration in the area around the charging pile body 2, inhibiting the continued combustion reaction, and fundamentally preventing the fire from spreading further, ensuring the safety of the charging pile, and reducing the harm of the fire to the charging facilities and the surrounding environment. At the same time, the dual effects of the isolation roll cover 310 and the fire extinguishing gas form a relatively closed and effective fire extinguishing space, avoiding the interference of external factors on the fire extinguishing process, improving the success rate and stability of fire extinguishing, and ensuring the safety of the charging pile body 2 in a fire.

[0045] It is worth noting that the liquid medicine loaded inside the two groups of liquid medicine buckets 42 has multiple options. Among them, the more typical combination is sodium carbonate solution and dilute hydrochloric acid, which can react chemically under certain conditions to quickly generate a large amount of carbon dioxide gas. Carbon dioxide gas has many excellent fire extinguishing properties. Its density is greater than that of air. After release, it will sink quickly and cover the surface of the fire area, effectively isolating the contact between oxygen and the burning material, thereby inhibiting the continuation of the combustion reaction. In addition to the combination of sodium carbonate solution and dilute hydrochloric acid, the liquid medicine bucket 42 can also be loaded with other types of fire extinguishing liquid according to actual needs and different fire extinguishing scenarios.

[0046] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
