[0047] The following combination Figures 1-7 The structure and shape of the fireproof charging cabinet provided in this embodiment are described in detail below:

[0048] The first fire extinguishing mechanism 200 includes: a first housing 230, a first storage tank 220, and a first output pipe 210; the first storage tank 220 is located inside the first housing 230; the inlet end of the first output pipe 210 is connected to the first storage tank 220, and the other end protrudes out of the first housing 230;

[0049] The second fire extinguishing mechanism 300 comprises a second shell 330, a second storage tank 320 and a second output pipe 310; the second storage tank 320 is located inside the second shell 330; the feeding end of the second output pipe 310 is in communication with the second storage tank 320, and the other end is in communication with the outside.

[0050] According to the scheme, the discharging end of the first output pipe 210 of the first fire extinguishing mechanism 200 protrudes outside the first shell 230, and the fire extinguishing medium can be directly sprayed outside the charging main body 100, so as to extinguish the external fire point.

[0051] In addition, since the second output pipe 310 of the second fire extinguishing mechanism 300 is in communication with the outside, and the second fire extinguishing mechanism 300 is located at the bottom of the charging main body 100, the ground fire point can be extinguished.

[0052] Regarding the shape and structure of the first fire extinguishing mechanism 200, more specifically:

[0053] The outlet of the first output pipe 210 is provided with a self-spraying outlet 211 and an external spraying outlet 212, and the self-spraying outlet 211 and the external spraying outlet 212 are arranged at an angle; the self-spraying outlet 211 faces the charging main body 100, and the external spraying outlet 212 faces the outside of the charging main body 100.

[0054] In order to control the switching between the self-spraying outlet 211 and the external spraying outlet 212, a first three-way valve is arranged between the self-spraying outlet 211 and the external spraying outlet 212; when the first three-way valve works in a first state, it not only extinguishes the burning point of the charging main body 100 itself, but also controls the fire extinguishing dry powder in the first output pipe 210 to be output from the self-spraying outlet 211; when the first three-way valve works in a second state, it not only extinguishes the burning point near the charging main body 100, but also controls the fire extinguishing dry powder in the first output pipe 210 to be output from the external spraying outlet 212.

[0055] In order to ensure the coverage effect of the self-spraying outlet 211 outputting the fire extinguishing medium, the self-spraying outlet 211 is arranged to face the middle part of the charging main body 100, and the fire extinguishing medium will produce a conical scattering effect after being output from the self-spraying outlet 211, thereby effectively covering the surface of the charging main body 100.

[0056] In order to adapt the external spray outlet 212 to different working environments, the angle between the external spray outlet 212 and the charging body 100 is set to be between 45°-76°, the height of the small charging pile in the prior art is between 1.5 meters, and the height of the large charging pile is more than 2.5 meters, according to the above angle setting, the output concentration point of the external spray outlet 212 on the horizontal plane is between 1.5 meters to 6 meters, when the external spray outlet 212 is aligned with the 1.5 meter output concentration point, the reaction force generated by the airflow impacting the ground can drive part of the fire extinguishing medium to be suspended in the air around the charging body 100 to form an atomized barrier, effectively absorbing the heat radiation transmitted from the burning point to the charging body 100, and according to the provisions of “GB50067-2014 Design of Garage, Repair Garage, Parking Lot Fire Prevention Specification”, the minimum fireproof distance between the parking lot and the building is 6 meters, and when the external spray outlet 212 is aligned with the 6 meter output concentration point, the fire extinguishing medium can extinguish the burning point at a distance of 6 meters from the charging body 100.

[0060] Regarding the power source of the first output pipe 210, more specifically:

[0061] The middle part of the first output pipe 210 is provided with a first pipe fan 213;

When the charging body 100 itself has a fire point, the airflow drives the fire extinguishing medium to be sprayed to the surface of the charging body 100 through the self-spraying outlet 211, and the fire extinguishing medium extinguishes the fire point. When the external of the charging body 100 has a fire point, the airflow drives the fire extinguishing medium to be sprayed through the external spraying outlet 212, and the fire extinguishing medium extinguishes the fire point.

[0068] The outlet of the second output pipe 310 is provided with a diffusion cover 311, and the inner cavity of the diffusion cover 311 is conical.

[0071] In order to ensure that the fire extinguishing medium in the second storage tank 320 moves to the second feeding port 314, the second feeding port 314 is close to the bottom of the inner wall of the second storage tank 320, and the fire extinguishing medium on the lower side of the second storage tank 320 enters the second output pipe 310 through the second feeding port 314, while the fire extinguishing medium on the upper side of the second storage tank 320 continuously moves downward under the action of gravity, thereby ensuring that there is fire extinguishing medium to be transported at the second feeding port 314.

[0072] Regarding the power source of the second output pipe 310, more specifically:

[0073] The middle part of the second output pipe 310 is provided with a second pipe fan 312.

[0074] When the second pipe fan 312 works in the first state, the fire extinguishing medium in the second storage tank 320 is sprayed out through the second output pipe 310.

[0075] In the optional scheme of the embodiment, more preferably:

[0076] The four sides of the charging body 100 are each provided with at least one second output pipe 310.

[0077] In order to control each second output pipe 310 respectively, the four sides of the charging body 100 are each provided with a fire sensor, which is the same as the fire sensor for controlling the first output pipe 210, and the fire sensor and the second output pipe 310 on the same side are signal connected, and the fire sensor has the function of detecting the burning point relative to the orientation of the charging body 100.

[0078] Regarding how to reduce the dead angle area covered by the fire extinguishing medium, more specifically:

[0079] The diffusion cover 311 is located at the corner of the second shell 330, and a plurality of diffusion covers 311 are arranged in a ring array.

[0080] In this scheme, the fire sensor controls the corresponding second output pipe 310 to start according to the position of the fire point relative to the charging body 100, the second pipe fan 312 drives external air to enter the second air inlet 315 in the form of airflow, the airflow in the second output pipe 310 flows through the second feeding port 314 at high speed, at this time, under the action of the Venturi effect, the fire extinguishing medium in the second storage tank 320 is sucked into the second output pipe 310 through the second feeding port 314 and mixed with the airflow, and the mixed flow of air and fire extinguishing medium in the second output pipe 310 is sprayed in a horizontal fan shape under the guidance of the diffusion cover 311, the sprayed fire extinguishing medium extinguishes the fire point outside the charging body 100 while forming a fire extinguishing isolation belt outside the charging body 100, when multiple groups of diffusion covers 311 spray fire extinguishing medium at the same time, the far point of the spray of the diffusion cover 311 is covered by the near point of the spray of the adjacent diffusion cover 311, thereby reducing the area of the dead angle covered by the fire extinguishing medium.

[0081] In order to avoid the accumulation of heat in the charging body 100 from self-igniting, the first heat dissipation device 400 is further provided.

[0082] Regarding the shape and structure of the first heat dissipation device 400, specifically:

[0083] Further comprising a first heat dissipation device 400, the first heat dissipation device 400 is located between the charging body 100 and the first fire extinguishing mechanism 200, and the first heat dissipation device 400 is connected with the first output pipe 210 through the first docking pipe 214;

[0084] When the first pipe fan 213 works in the second state, external cooling air enters the first heat dissipation device 400 through the first output pipe 210.

[0085] To achieve the heat dissipation function, the shape and structure of the first heat dissipation device 400 are more detailed: the first heat dissipation device 400 includes a first finned heat dissipation seat and a plurality of first heat dissipation fans, the first heat dissipation fans are installed in the part of the first finned heat dissipation seat embedded in the charging main body 100, which is responsible for accelerating the air flow in the charging main body 100 through the first finned heat dissipation seat, and the first docking pipe 214 is installed in the part of the first finned heat dissipation seat protruding from the charging main body 100.

[0086] To make the first output pipe 210 communicate with the first docking pipe 214, a second three-way valve is arranged between the first output pipe 210 and the first docking pipe 214, when the second three-way valve works in the first state, the first fire extinguishing mechanism 200 performs fire extinguishing operation, and the first output pipe 210 is disconnected with the first docking pipe 214, when the second three-way valve works in the second state, the first heat dissipation device 400 performs heat dissipation operation assisted by the first fire extinguishing mechanism 200, and the first pipe fan 213 drives air to enter the first docking pipe 214 through the first output pipe 210.

[0087] In this scheme, the second three-way valve controls the communication between the first output pipe 210 and the first docking pipe 214, and then the first pipe fan 213 drives external cooling air to enter the first output pipe 210, the cooling air in the first output pipe 210 is injected into the outer heat dissipation end of the first finned heat dissipation seat of the first heat dissipation device 400 under the action of pressure, the cooling air exchanges heat with the outer heat dissipation end of the first finned heat dissipation seat, and the heat on the first finned heat dissipation seat is taken away, at the same time, the first heat dissipation fan drives the air in the charging main body 100 to circulate through the inner heat dissipation end of the first finned heat dissipation seat, in this process, the airflow exchanges heat with the inner heat dissipation end of the first finned heat dissipation seat, and the heat in the charging main body 100 is transferred to the first finned heat dissipation seat, thereby achieving the purpose of discharging the heat accumulated in the charging main body 100.

[0088] To improve the heat dissipation effect of the charging main body 100, the second heat dissipation device 500 is also provided.

[0089] Regarding the shape and structure of the second heat dissipation device 500, specifically:

[0090] Further comprising a second heat dissipation device 500, the second heat dissipation device 500 is located between the charging main body 100 and the second fire extinguishing mechanism 300, and the second heat dissipation device 500 is connected with the second output pipe 310 through the second docking pipe 313;

[0091] When the second pipe fan 312 works in the second state, external cooling air enters the second heat dissipation device 500 through the second output pipe 310.

[0092] To achieve the heat dissipation function, the shape and structure of the second heat dissipation device 500, more specifically: the second heat dissipation device 500 includes a second finned heat sink and a plurality of second heat dissipation fans, the second heat dissipation fan is installed in the part of the second finned heat sink embedded in the charging body 100, which is responsible for accelerating the air flow in the charging body 100 through the second finned heat sink, and the second docking pipe 313 is installed in the part of the second finned heat sink protruding from the charging body 100.

[0093] To make the second output pipe 310 communicate with the second docking pipe 313, a third three-way valve is arranged between the second output pipe 310 and the second docking pipe 313. When the third three-way valve works in the first state, the second fire extinguishing mechanism 300 performs fire extinguishing operation, and the second output pipe 310 is disconnected with the second docking pipe 313. When the third three-way valve works in the second state, the second heat dissipation device 500 is assisted by the second fire extinguishing mechanism 300 to perform heat dissipation operation, and the second pipe fan 312 drives air to enter the second docking pipe 313 through the second output pipe 310.

[0094] In this scheme, the third three-way valve controls the communication between the second output pipe 310 and the second docking pipe 313, and then the second pipe fan 312 drives external cooling air into the second output pipe 310. The cooling air in the second output pipe 310 is injected into the outer heat dissipation end of the second finned heat sink of the second heat dissipation device 500 under the action of pressure. The cooling air exchanges heat with the outer heat dissipation end of the second finned heat sink, taking away the heat on the second finned heat sink. At the same time, the second heat dissipation fan drives the air in the charging body 100 to circulate through the inner heat dissipation end of the second finned heat sink. In this process, the airflow exchanges heat with the inner heat dissipation end of the second finned heat sink, transferring the heat in the charging body 100 to the second finned heat sink, thereby achieving the purpose of discharging the heat accumulated in the charging body 100.

[0095] The cooperation of the first fire extinguishing mechanism and the second fire extinguishing structure realizes the extinguishing work of the middle-high position and the ground fire point. Specifically:

[0096] When the fire extinguishing medium in the first storage tank 220 is output through the first output pipe 210, the fire extinguishing medium output at the outlet of the first output pipe 210 extinguishes the burning point at the middle-high position near the charging body 100. When the fire extinguishing medium in the second storage tank 320 is output through the second output pipe 310, the fire extinguishing medium output at the outlet of the second output pipe 310 extinguishes the burning point at the middle-low position near the charging body 100. At the same time, the output of the fire extinguishing medium forms a fire extinguishing isolation belt around the charging body 100.
