DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figure 1 In this embodiment, a charging pile with good fire resistance includes a charging pile body 1. A fixing box 2 is fixed on the upper surface of the charging pile body 1. An isolation mechanism 3 for isolating oxygen is provided at the left end of the inner top wall of the fixing box 2. A fire extinguishing mechanism 4 for extinguishing fire is provided at the right end of the inner top wall of the charging pile body 1. A plurality of ventilation holes 5 are provided at the bottom of the opposite sides of the left and right side walls of the inner cavity of the charging pile body 1.

[0023] See also Figures 2 to 3In order to reduce the labor intensity of the staff, the isolation mechanism 3 in this embodiment includes a drive motor 301 fixed to the left end of the inner top wall of the fixed box 2, and support plates 302 are fixed on the opposite sides of the left and right side walls of the inner cavity of the charging pile body 1. The upper surface of the support plate 302 is rotatably connected to a threaded rod 303 with one end penetrating the inner top wall of the charging pile body 1 and extending to the inner cavity of the fixed box 2 through a bearing. The output shaft of the drive motor 301 is fixed to the left end threaded rod 303, and a sprocket 304 is fixed to the outer surface of the threaded rod 303. The two sprockets 304 are connected by a chain transmission, and the sprocket 304 is meshed with the chain. The drive motor 3 The rotation of the output shaft of 01 drives the rotation of the left end threaded rod 303, and the rotation of the left end threaded rod 303 drives the rotation of the sprocket 304 fixed on its surface. The rotation of the sprocket 304 causes the chain to drive the rotation of the right end sprocket 304 and the right end threaded rod 303. The outer surface of the threaded rod 303 is threadedly connected with a movable sleeve 305, and the front of the movable sleeve 305 is fixed with a connecting plate 306, and the lower surface of the connecting plate 306 is fixed with a baffle 307. The rotation of the two threaded rods 303 causes the movable sleeve 305 threadedly connected thereto to move downward under the action of the limit block and the limit groove, thereby causing the connecting plate 306 to drive the baffle 307 to move downward.

[0024] Among them, the threaded rod 303 is rotatably connected to the inner top wall of the charging pile body 1 and the inner bottom wall of the fixed box 2 through bearings, the upper surface of the right end threaded rod 303 is rotatably connected to the inner top wall of the fixed box 2 through bearings, the size of the baffle 307 is larger than the size of the vent 5 and the distance from the uppermost vent 5 to the lowermost vent 5, and the cross-sectional shape of the connecting plate 306 is an inverted L shape.

[0025] In this embodiment, limiting grooves are provided on the opposite sides of the left and right side walls of the inner cavity of the charging pile body 1, and limiting blocks are fixed on the opposite sides of the two movable sleeves 305. The limiting blocks move linearly up and down in the inner cavity of the limiting grooves. Limiting strips are fixed on the bottoms of the front and rear ends of the opposite sides of the left and right side walls of the inner cavity of the charging pile body 1. The baffle 307 moves linearly up and down between the opposite sides of the front and rear limiting strips. A rubber block is fixed at the bottom between the opposite sides of the front and rear limiting strips until the baffle 307 moves to the bottom of the two limiting strips and fits with the rubber block, thereby blocking multiple vents 5 and making the charging pile body 1 in a sealed state, thereby isolating the charging pile body 1 from oxygen and preventing the fire from spreading.

[0026] It should be noted that the isolation mechanism 3 can automatically move the baffle 307 up and down, which greatly reduces the labor intensity of the staff and prevents the staff from contacting and scalding.

[0027] See also Figure 4In order to suppress the burning of the flame, the fire extinguishing mechanism 4 in this embodiment includes an aerosol intelligent fire prevention device 401 fixed to the right end of the inner top wall of the charging pile body 1. The output end of the aerosol intelligent fire prevention device 401 is fixed with an electromagnetic control valve 402. The right side of the electromagnetic control valve 402 is connected to a hollow tube 403 fixed to the inner top wall of the charging pile body 1. The lower surface of the hollow tube 403 is connected to multiple nozzles 404. The controller can control the start-up of the aerosol intelligent fire prevention device 401 and open the electromagnetic control valve 402. After startup, the aerosol propellant quickly passes through the electromagnetic control valve 402 into the inner cavity of the hollow tube 403 and is finally released through multiple nozzles 404 to form tiny aerosol particles.

[0028] Among them, a controller and a smoke sensor 405 are fixed from left to right on the left end of the top wall of the charging pile body 1, a temperature sensor 406 is fixed on the bottom of the right side wall of the inner cavity of the charging pile body 1, and multiple nozzles 404 are evenly distributed on the lower surface of the hollow tube 403. The temperature sensor 406 and the smoke sensor 405 are set to monitor the temperature and smoke in the charging pile body 1 in real time. If the temperature sensor 406 and the smoke sensor 405 detect abnormal temperature and smoke respectively, they can transmit signals to the controller.

[0029] In this embodiment, the aerosol intelligent fire prevention device 401 is an existing mechanism and will not be described in detail here. The aerosol particles have a very high specific surface area and can quickly absorb the heat around the flame and form a dense cloud of fire extinguishing agent in the fire area. At the same time, the chemical components in the aerosol particles will react chemically with the free radicals in the flame and the active substances in the free radical chain reaction, inhibiting the combustion process of the flame and causing the flame temperature to drop rapidly, thereby achieving the effect of extinguishing the fire.

[0030] In addition, a reminder is provided in the controller for transmitting a signal to the control center to notify the staff when a fire occurs in the charging pile body 1.

[0031] The electrical components appearing in the text are all electrically connected to the main controller and the power supply, and the electrical components appearing in the text are all conventionally known devices. This application will not go into too much detail. The main controller can be a conventionally known device that controls a computer, etc. The control circuit of the main controller can be implemented by simple programming by technicians in this field. The provision of power is also common knowledge in this field, and this application is mainly used to protect mechanical devices, so this application will no longer explain the control method and circuit connection in detail.

[0032] The working principle of the above embodiment is:

[0033] (1) The temperature and smoke in the charging pile body 1 can be monitored in real time by the temperature sensor 406 and the smoke sensor 405. If the temperature sensor 406 and the smoke sensor 405 detect abnormal temperature and smoke respectively, they can send a signal to the controller. The controller can control the start of the aerosol intelligent fire protection device 401 and open the electromagnetic control valve 402. After starting, the aerosol propellant quickly passes through the electromagnetic control valve 402 into the inner cavity of the hollow tube 403 and is finally released through multiple nozzles 404 to form tiny aerosol particles. These particles have a very high specific surface area and can quickly absorb the heat around the flame and form a dense cloud of fire extinguishing agent in the fire area. At the same time, the chemical components in the aerosol particles will react chemically with the free radicals in the flame and the active substances in the free radical chain reaction, inhibiting the combustion process of the flame and causing the flame temperature to drop rapidly, thereby achieving the effect of extinguishing the fire.

[0034] (2) When abnormal temperature and smoke are detected, the controller starts the driving motor 301 synchronously. The output shaft of the driving motor 301 rotates to drive the left-end threaded rod 303 to rotate. The rotation of the left-end threaded rod 303 drives the sprocket 304 fixed on its surface to rotate. The rotation of the sprocket 304 causes the chain to drive the right-end sprocket 304 and the right-end threaded rod 303 to rotate. The rotation of the two threaded rods 303 causes the movable sleeve 305 threadedly connected thereto to move downward under the action of the limit block and the limit groove, thereby causing the connecting plate 306 to drive the baffle 307 to move downward until the baffle 307 moves to the bottom of the two limit bars and fits with the rubber block, thereby blocking multiple vents 5 and making the charging pile body 1 in a sealed state, thereby isolating the charging pile body 1 from oxygen and preventing the fire from increasing.
