DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

[0024] In order to make the purpose, technical solutions and advantages of the implementation methods of this application clearer, the technical solutions in the implementation methods of this application will be clearly and completely described below in conjunction with the drawings in the implementation methods of this application. Obviously, the described implementation methods are part of the implementation methods of this application, not all of the implementation methods. Based on the implementation methods in this application, all other implementation methods obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0025] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for protection, but merely represents the selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0026] An electric bicycle charging station with an automatic fire extinguishing function according to an embodiment of the present application is described below with reference to the accompanying drawings.

[0027] See also Figure 1-Figure 10 According to an embodiment of the present application, an electric bicycle charging pile with an automatic fire extinguishing function includes: a charging pile control box main body 10, a fire extinguishing main body 20 and a diversion, dispersion and dust prevention part 30.

[0028] Among them, through the cooperation of the charging pile control box main part 10 and the fire extinguishing main part 20, the interior of the main box 110 is quickly filled with carbon dioxide. The carbon dioxide inside the main box 110 blocks the contact between the fire source and the air, and can quickly and efficiently realize automatic fire extinguishing, effectively avoiding losses caused by fire.

[0029] See also Figure 1-Figure 6 The main part 10 of the charging pile control box includes a main box 110, a box door 120 and a monitoring sensor group 130. The main box 110 is arranged in front of the box door 120, and the monitoring sensor group 130 is installed inside the main box 110. The fire extinguishing main part 20 includes a carbon dioxide storage tank 210, an air outlet pipe 220, an atomizing nozzle 230 and a mounting base plate 250. The mounting base plate 250 is fixed to one side of the main box 110, the carbon dioxide storage tank 210 is mounted on one side of the mounting base plate 250, and the atomizing nozzle 230 is arranged inside the main box 110. The bottom end of the air outlet pipe 220 is connected to the air outlet at the bottom end of the carbon dioxide storage tank 210, and the other end of the air outlet pipe 220 passes through the side wall of the main box 110 and is connected to the atomizing nozzle 230. A solenoid valve 240 is installed outside the air outlet pipe 220. Among them, the monitoring sensor group 130 can use a temperature sensor and a flame sensor.

[0030] The working principle of the electric bicycle charging pile with automatic fire extinguishing function is as follows: when the flame sensor in the monitoring sensor group 130 receives a signal, the electromagnetic valve 240 is controlled to open by the control system inside the charging pile, and the liquid carbon dioxide inside the carbon dioxide storage tank 210 is converted into gaseous state through the outlet pipe 220, and finally quickly sprayed out through the atomizing nozzle 230 and dispersed inside the main box 110. At this time, the inside of the main box 110 is filled with carbon dioxide gas, which quickly reduces the concentration of oxygen in the air inside the main box 110, and the fire source inside the main box 110 can no longer be ignited, which plays a role in rapid fire extinguishing. When the carbon dioxide in the carbon dioxide storage tank 210 is sprayed into the surface of the electrical components inside the main box 110 through the outlet pipe 220 and the atomizing nozzle 230, the electrical components can be quickly cooled down, the temperature of the fire source can be reduced, and the speed of fire extinguishing inside the charging pile cabinet can be further improved. That is, the automatic and rapid fire extinguishing inside the charging pile control cabinet is realized, and the losses caused by the fire are effectively avoided.

[0031] The temperature sensor in the monitoring sensor group 130 is used to monitor the temperature inside the main box 110. When the temperature inside the main box 110 is higher than the preset value of the temperature sensor in the monitoring sensor group 130, the control system will also open the solenoid valve 240 for three seconds, and the overpressure hot carbon dioxide inside the carbon dioxide storage tank 210 will eventually be sprayed from the atomizing nozzle 230 to the inside of the main box 110 through the outlet pipe 220, so that the electrical components inside the main box 110 are in contact with the low-temperature carbon dioxide gas, so that the electrical components inside the main box 110 can be quickly cooled down, and the temperature inside the charging pile control cabinet is reduced, and the tendency of fire inside the charging pile control cabinet is cut off from the source, which has the effect of preventing fire.

[0032] The above-mentioned method of spraying carbon dioxide gas directly into the main box 110 by the atomizing nozzle 230 can only be aimed at some electrical components inside the main box 110, and cannot evenly spray carbon dioxide at all electrical components for rapid cooling.

[0033] See also Figure 4 , Figure 7 and Figure 8The guide, dispersion and dust-proof part 30 includes an exhaust guide shell 310, a seat tube 320 and an elastic sealing member 330. The exhaust guide shell 310 can be installed at the top of the main chassis 110 by means of rivets or bolts, and a plurality of exhaust holes 340 are arranged at the bottom of the exhaust guide shell 310. The elastic sealing member 330 blocks and releases the gas inside the exhaust guide shell 310 through the exhaust holes 340. The top of the seat tube 320 is connected to the exhaust guide shell 310, and the atomizing nozzle 230 is installed inside the seat tube 320. The elastic sealing member 330 includes a support block 331, a pressure rod 332, a sealing block 333 and a spring 334. The sealing block 333 is located below the exhaust hole 340, and the sealing block 333 can be made of a relatively hard rubber block. The support block 331 is located inside the exhaust guide shell 310 , the pressure rod 332 connects the support block 331 and the sealing block 333 , and the spring 334 is sleeved outside the pressure rod 332 located between the exhaust hole 340 and the support block 331 .

[0034] When the solenoid valve 240 is opened, the liquid carbon dioxide inside the carbon dioxide storage tank 210 enters the outlet pipe 220 under pressure and then changes into gaseous state, and is sprayed into the seat tube 320 through the atomizing nozzle 230, that is, enters the exhaust guide shell 310 through the seat tube 320. The air pressure inside the exhaust guide shell 310 increases, and the over-pressure carbon dioxide gas will press down the sealing block 333 below the exhaust hole 340, and the downward movement of the sealing block 333 drives the pressure rod 332 and the support block 331 to move downward to compress the spring 334. At this time, there is a gap between the sealing block 333 and the bottom wall of the exhaust guide shell 310, and the over-pressure carbon dioxide gas inside the exhaust guide shell 310 will be discharged to the inside of the main chassis 110 through the exhaust hole 340 and the gap between the bottom of the exhaust guide shell 310 and the sealing block 333 in sequence. The carbon dioxide gas inside the exhaust guide shell 310 is discharged through the multiple exhaust holes 340 at the bottom of the exhaust guide shell 310. Since carbon dioxide gas is heavier than oxygen, the carbon dioxide gas discharged into the main chassis 110 is gradually dropped to the bottom of the main chassis 110 due to the pressure from the top of the main chassis 110 and its own gravity, so that the carbon dioxide gas discharged into the main chassis 110 can evenly and quickly fill the electrical components in contact with the main chassis 110, thereby achieving a better cooling effect.

[0035] In the above specific implementation, please refer to Figure 6The fire extinguishing main body 20 also includes a fixed ring plate 291, which is fixedly sleeved on the outside of the atomizing nozzle 230, and the outer wall of the fixed ring plate 291 is fixedly connected to the inner wall of the seat tube 320. The fire extinguishing main body 20 also includes a sealing ring 292, which is located above the fixed ring plate 291, and the sealing ring 292 is sleeved on the outside of the atomizing nozzle 230 to seal the gap between the atomizing nozzle 230 and the seat tube 320. The fixed ring plate 291 and the seat tube 320 can be integrally formed, and the sealing ring 292 is used to seal the gap between the atomizing nozzle 230 and the inner wall of the seat tube 320. When the carbon dioxide gas discharged from the atomizing nozzle 230 reaches the inside of the seat tube 320 and the exhaust guide shell 310, it will not leak out from the gap between the atomizing nozzle 230 and the seat tube 320. Furthermore, the atomizing nozzle 230 has a certain recoil force when spraying carbon dioxide, and the fixed ring plate 291 is used to limit and support the atomizing nozzle 230.

[0036] Furthermore, a liquid filling port 270 is provided at the gas outlet on the top of the carbon dioxide storage tank 210, and a one-way valve 280 is installed outside the liquid filling port 270. Liquid carbon dioxide can be pressurized and injected into the carbon dioxide storage tank 210 through the liquid filling port 270 and the one-way valve 280.

[0037] For details, please refer to Figure 3 and Figure 5 The fire extinguishing main body 20 also includes a protective belt 260, which is enclosed outside the carbon dioxide storage tank 210 and connected to the mounting base plate 250. The protective belt 260 cooperates with the mounting base plate 250 to stably install the carbon dioxide storage tank 210. The bottom of the main box 110 is provided with a corresponding wire through-hole 140, and the wire through-hole 140 is provided for installing wires.

[0038] In the specific configuration, the main body 10 of the charging pile control box also includes a shield shell 150, which covers the outside of the carbon dioxide storage tank 210 and the air outlet pipe 220 exposed on the outside of the main box 110. Ear plates are provided on the top and bottom of the shield shell 150, and the ear plates are detachably mounted with the main box 110 through bolts. The shield shell 150 is used to protect the carbon dioxide storage tank 210, and the shield shell 150 can be disassembled to add liquid carbon dioxide into the carbon dioxide storage tank 210.

[0039] The above-mentioned electric bicycle charging pile with automatic fire extinguishing function discharges the carbon dioxide gas in the exhaust guide shell 310 into the interior of the main case 110 from the exhaust hole 340 at the bottom of the exhaust guide shell 310, and quickly passes to the interior of the main case 110 through the pressure of the carbon dioxide gas in the exhaust guide shell 310 and its own gravity. If the carbon dioxide gas discharged from the exhaust hole 340 can be further quickly filled with the interior of the main case 110, it will have a better cooling effect.

[0040] See also Figure 2 , Figure 3 , Fig. 9 and Fig.10 The electric bicycle charging pile with automatic fire extinguishing function also includes an exhaust air return moisture-proof part 40, which includes an exhaust fan 410, a U-shaped vertical guide pipe shell 420 and a guide shell 430. A mounting slot 160 is provided in the middle of the lower part of the main case 110, and a plurality of ventilation holes 170 are provided at the lower rear side of the main case 110. The exhaust fan 410 is installed inside the mounting slot 160, and the vertical guide pipe shell 420 is provided at the rear side of the main case 110. A guide cavity is formed between the vertical guide pipe shell 420 and the bottom wall and side wall inside the main case 110. The ventilation holes 170 at the bottom of the main case 110 are connected to the guide cavity inside the vertical guide pipe shell 420, and the guide shell 430 is provided at the bottom of the main case 110, and the guide shell 430 connects the mounting slot 160 and the ventilation holes 170. The guide housing 430 includes a strip housing 431, a blocking housing 432 and a connecting housing 433. The strip housing 431 is located below the vent 170, the blocking housing 432 is located below the mounting slot 160, and the two ends of the connecting housing 433 are connected to the strip housing 431 and the blocking housing 432 respectively. The strip housing 431, the blocking housing 432 and the connecting housing 433 are all fixed to the bottom of the main chassis 110.

[0041] When the temperature sensor in the monitoring sensor group 130 detects that the temperature inside the main box 110 is higher than the preset value, the control system inside the charging pile controls the solenoid valve 240 and the exhaust fan 410 to start at the same time. The carbon dioxide inside the carbon dioxide storage tank 210 is finally discharged from the atomizing nozzle 230 into the exhaust guide shell 310 through the outlet pipe 220. The over-pressure carbon dioxide gas inside the exhaust guide shell 310 is pre-exhausted to the top area inside the main box 110 through the exhaust hole 340 at the bottom. The running exhaust fan 410 drives the carbon dioxide gas inside the main case 110 to circulate, that is, the circulating carbon dioxide gas is discharged from the top into the blocking shell 432 below the mounting groove 160, and then enters the guide shell 430. The carbon dioxide gas inside the blocking shell 432 flows back to the inside of the vertical guide tube shell 420 through the connecting shell 433 and the strip shell 431, and then flows back to the inside of the vertical guide tube shell 420 through the vent 170 at the bottom of the main case 110, and finally is discharged into the top area of ​​the main case 110 through the cavity inside the vertical guide tube shell 420. Since the carbon dioxide gas discharged during cooling is three seconds, the low-temperature carbon dioxide gas circulates from top to bottom inside the main case 110 and quickly passes through the outer surface of the electrical components inside the main case 110, so that the electrical components are further cooled quickly. The carbon dioxide gas discharged and circulated into the blocking shell 432 through the exhaust fan 410 can still be recycled repeatedly, and the gas circulation method is used for cooling.

[0042] The monitoring sensor group 130 may also include a humidity sensor. When the humidity inside the main box 110 reaches a certain index, the control system inside the charging pile controls the solenoid valve 240 and the exhaust fan 410 to start. It takes five seconds for the gas inside the carbon dioxide storage tank 210 to be discharged into the main box 110. The running exhaust fan 410 repeatedly circulates the carbon dioxide gas inside the main box 110 inside the main box 110 through the setting of the guide shell 430 and the vertical guide tube shell 420. The flowing carbon dioxide gas repeatedly contacts the surface of the electrical components inside the main box 110, and the temperature of the carbon dioxide gas gradually increases. The increased carbon dioxide gas can accelerate the volatilization of water vapor inside the main box 110, and has a good dehumidification effect. When the temperature inside the main box 110 reaches the preset value of the temperature sensor in the monitoring sensor group 130, the exhaust fan 410 stops running. (The temperature of carbon dioxide inside the main box 110 cannot be too high, that is, the temperature sensor is set with at least two preset values. One is a higher temperature, and the control system controls the solenoid valve 240 and the exhaust fan 410 to start. The other is a relatively low preset value. When the carbon dioxide inside the main box 110 is repeatedly circulated and dehumidified, the main box 110 reaches a temperature, and the exhaust fan 410 will be stopped by the control system.) The electric bicycle charging pile with automatic fire extinguishing function can further quickly cool down the electrical components inside the main box 110, and can also have a good dehumidification effect, protecting the electrical components inside the charging pile control cabinet for a long service life.
