DETAILED DESCRIPTION

[0020] In order to make the technical problems to be solved by the present application, technical solutions and beneficial effects more clear, the present application is further described in detail below in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the present application, and do not limit the present application, and all other examples obtained by those of ordinary skill in the art without creative labor fall within the scope of the present application.

[0021] Please refer to Figures 1-6 , the present application provides a charging pile, specific implementation scheme as follows: As Figures 1-4 shown, a charging pile, comprising a charging box 1, the upper part of the charging box 1 is provided with a fire-fighting module 2, the bottom of the charging box 1 is connected with a charging gun 4 through an electric wire 5; The fire-fighting module 2 comprises a placing box 21, a gas fire extinguisher 211, a gas pipe 22, a gas delivery guide pipe 23, a heat-sensitive block 24, a hooking rope 25, an electrically isolating sheet 251, a hooking spring 252, a connecting spring 26, a first sealing ring 221, a second sealing ring 231, a heat-sensitive ball 234 and an alarm 252. The placing box 21 is arranged above the charging box 1, and the gas fire extinguisher 211 is arranged in the placing box 21. One end of the gas pipe 22 is connected to the side of the gas fire extinguisher 211, and the other end of the gas pipe 22 is arranged in the charging box 1 through the side of the charging box 1. The other end of the gas pipe 22 is sleeved with the gas delivery guide pipe 23. The heat-sensitive ball 234 is sleeved with the gas pipe 22 at the end away from the gas fire extinguisher 211. The gas delivery guide pipe 23 is provided with a circular arc-shaped blocking through hole 233 at the end connected with the heat-sensitive ball 234. The end of the gas delivery guide pipe 23 connected with the blocking through hole 233 is matched with the shape of the heat-sensitive ball 234. One end of the hooking rope 25 is connected to the end of the gas delivery guide pipe 23 close to the heat-sensitive ball 234. The other end of the hooking rope 25 is led out to the upper side of the placing box 21 through the top end of the charging box 1 and the placing box 21 and is connected with the alarm 252. The electrically isolating sheet 251 is arranged between the hooking rope 25 and the alarm 252. The hooking spring 252 is sleeved with the hooking rope 25 outside. The hooking spring 252 is arranged in the charging box 1 and is connected with the top of the charging box 1. The first sealing ring 221 is arranged between the heat-sensitive ball 234 and the gas pipe 22. The first sealing ring 221 is matched with the connection between the gas pipe 22 and the heat-sensitive ball 234. The first sealing ring 221 prevents the gas from entering the charging box 1 through the gap between the gas pipe 22 and the heat-sensitive ball 234 by being connected with the gas pipe 22 and the heat-sensitive ball 234. The second sealing ring 231 is arranged at the end of the gas delivery guide pipe 23 away from the heat-sensitive ball 234. The second sealing ring 231 is sleeved with the outside of the gas pipe 22. The second sealing ring 231 is arranged between the outside of the gas pipe 22 and the gas delivery guide pipe 23 to seal the gap between the gas pipe 22 and the gas delivery guide pipe 23. The connecting slide rail 27 is arranged at the outside of the gas delivery guide pipe 23 away from the placing box 21. One end of the connecting spring 26 is arranged at the side of the charging box 1 close to the second sealing ring 231. The other end of the connecting spring 26 is connected with a sliding sheet. The sliding sheet is slidingly connected with the connecting slide rail 27. The connecting spring 26 slides in the sliding slide rail when the sliding sheet slides. The connecting spring 26 can slide in the connecting slide rail 27 when the gas delivery guide pipe 23 is connected with the charging box 1 through the heat-sensitive block 24. One end of the connecting spring 26 slides to the position with the smallest bending degree in the connecting slide rail 27, thereby reducing the bending degree of the connecting spring 26 and the plastic deformation of the connecting spring 26 to a certain extent. The gas delivery guide pipe 23 and the gas pipe 22 are respectively provided with one end of the leakage pipe 232. The gas delivery guide pipe 23 is provided with a plurality of one ends of the leakage pipe 232 at the contact surface of the gas delivery guide pipe 23 and the heat-sensitive ball 234. The other end of the leakage pipe 232 penetrates the gas delivery guide pipe 23 and reaches the gas pipe 22 near the second sealing ring 231. A plurality of small holes are arranged between the leakage pipe 232 and the outer side of the gas delivery guide pipe 23. The small holes are used to guide the gas from the contact surface of the gas delivery guide pipe 23 and the heat-sensitive ball 234 to the leakage pipe 232 in the case of the rupture of the heat-sensitive ball 234, and then the gas is guided to the charging box 1 through the small holes. The outer side of the gas delivery guide pipe 23 is connected with the heat-sensitive block 24 between the top end of the charging box 1. The heat-sensitive block 24 is fixed with the charging box 1. In the case of fire, the heat-sensitive block 24 is heated, and then the liquid inside the heat-sensitive block 24 is heated and expanded, which causes the plastic outside the liquid to break, so that the heat-sensitive block 24 is broken as a whole. The connection spring 26 is deformed, so that the force of the deformed connection spring 26 drives the gas pipe 22 and the gas delivery guide pipe 23 to move in the charging box 1 towards the bottom of the charging box 1. Then, the liquid inside the heat-sensitive ball 234 is heated and expanded, which causes the plastic outside the liquid to break, and then the heat-sensitive ball 234 is broken. At this time, the gas pipe 22 can transport the gas with fire extinguishing function in the gas extinguisher 211 to the inside of the charging box 1 through the small holes and the blocking through hole 233, so as to play a role in relieving the fire and extinguishing the initial fire. At the same time, when the gas pipe 22 and the gas delivery guide pipe 23 move towards the bottom of the charging box 1, one end of the hook connecting rope 25 connected with the gas delivery guide pipe 23 will be subjected to the force generated by the movement of the gas pipe 22 and the gas delivery guide pipe 23 towards the bottom of the charging box 1, and then the other end of the hook connecting rope 25 will be subjected to the force, so as to control the separation of the electrically isolated sheet 251 and the alarm 252. When the gas pipe 22 and the gas delivery guide pipe 23 start to move towards the bottom of the charging box 1 under the force generated by the deformation of the connection spring 26 after the heat-sensitive block 24 is broken, the hook spring 252 will also generate a certain force due to the deformation. Since the connection spring 26 and the hook spring 252 start to deform at the same time after the heat-sensitive block 24 is broken, the gas delivery guide pipe 23 will not be attached to a certain surface of the charging box 1 due to the traction of a part of the connection spring 26 and the hook spring 252 under the joint action of the connection spring 26 and the hook spring 252. After the heat-sensitive block 24 is broken, the gas delivery guide pipe 23 will sway due to the contraction of the connection spring 26 and the stretching of the hook spring 252, until the deformation of the connection spring 26 and the hook spring 252 stops. Then, the gas delivery guide pipe 23 will be inclined to the bottom of the charging box 1, and the gas overflowing from the surface of the gas delivery guide pipe 23 will cover a larger area in the charging box 1, so as to maximize the fire extinguishing effect. After the insulating sheet 251 is separated from the alarm 252, the internal circuit of the alarm 252 is connected, and the alarm 252 starts to work. The sound emitted by the alarm 252 notifies people that the charging box 1 has caught fire, so that fire safety personnel can grasp the relevant situation of the fire in a timely manner.

[0022] like Figures 5-6 As shown, the charging box 1 has a detachment module 3 on the side away from the air tube 22. The detachment module 3 gradually moves away from the placement box 21 from one end inside the charging box 1 to the other end outside the charging box 1. The detachment module 3 is located on the side of the charging box 1 away from the air tube 22. The detachment module 3 includes a connecting ring 31, a locking block 32, a locking spring 33, an airbag strip 34, and a storage tube 35. The connecting ring 31 is sleeved on the side of the charging box 1. One end of the storage tube 35 is coaxially sleeved on the connecting ring 31. The other end of the storage tube 35 is connected to the charging box 1. Gun 4 is movably connected. The axes of the connecting ring 31 and the storage tube 35 are oriented towards the ground. The outer side of the storage tube 35 is provided with a locking groove 351. Several locking springs 33 are arranged in a circular array at the locking groove 351. Each locking spring 33 is connected to a locking block 32. The overall shape of the locking block 32 is arc-shaped. Each locking block 32 is arranged in a circular array coaxially around the storage tube 35. The inner side of the connecting ring 31 is provided with an airbag groove 311. The outer side of the connecting ring 31 is provided with an outlet through hole 312 away from the placement box 21. The two ends of the through hole 312 are connected to the airbag groove 311 and the inside of the charging box 1, respectively. The airbag strip 34 is arranged around the outer side of the connecting ring 31 along the airbag groove 311. The airbag strip 34 extends from the through hole 312 into the inside of the charging box 1. An airbag ball 341 is provided at the end of the airbag strip away from the connecting ring 31. The locking block 32 is controlled by the locking spring 33 to contact the airbag strip 34 in the airbag groove 311, and controls the side of the locking block 32 to contact the side of the airbag groove 311. The inside of the airbag ball 341 and the inside of the airbag strip 34 are both filled with gas that expands when heated. The inside of the airbag ball 341 is connected to the inside of the airbag strip 34. In the event of a fire, the gas... When the balloon 341 is heated, the gas inside the balloon 341 and the airbag strip 34 expands due to the heat. As a result, the airbag strip 34 expands as a whole, and each locking block 32 is subjected to the force exerted by the airbag strip 34 and moves towards the locking spring 33. The locking spring 33 then contracts until the locking block 32 is completely removed from the airbag groove 311. As a result, the storage tube 35 loses the support of the connecting ring 31, and the storage tube 35, together with the connected charging gun 4, detaches from the connecting ring 31 and the charging box 1. This can prevent the charging gun 4 and its connected wire 5 from being affected by the fire in the event of fire spread, and can effectively prevent the fire from getting out of control.

[0023] The working process of the embodiment is as follows: when a fire occurs in the charging box 1, the temperature in the charging box 1 rises, and the rising temperature causes the thermal sensitive block 24 and the thermal sensitive ball 234 to break, the air pipe 22 and the gas conveying guide pipe 23 are deformed to shrink by the connecting spring 26 and then move towards the bottom of the charging box 1, at the same time, the hook connecting rope 25 is displaced with the gas conveying guide pipe 23, the hook connecting rope 25 drives the electric isolation sheet 251 to separate from the alarm 252, the bottom end of the hook connecting spring 252 moves with the hook connecting rope 25, and then the hook connecting spring 252 is deformed to stretch, the connecting spring 26 and the hook connecting spring 252 jointly control the gas conveying guide pipe 23 to be arranged in a form of not adhering to the inner side of the charging box 1 and inclined to the bottom surface of the charging box 1, at the same time, the gas in the air pipe 22 overflows into the charging box 1 due to the loss of the block of the thermal sensitive ball 234, so as to extinguish the fire point in the charging box 1. At the same time with the breaking of the thermal sensitive block 24 and the thermal sensitive ball 234, the gas in the air bag ball 341 and the air bag strip 34 is expanded due to the expansion of the air bag ball 341 caused by heat, the clamping block 32 inserted into the air bag groove 311 is pushed out of the air bag groove 311 by the air bag strip 34, the storage pipe 35 loses the supporting force provided by the connecting ring 31, and the storage pipe 35 slides together with the charging gun 4 along the axis direction of the connecting ring 31 towards the outside of the charging box 1.

[0024] The basic principles, main features and advantages of the present application are shown and described above. It should be understood by those skilled in the art that the present application is not limited by the above embodiments, the above embodiments and the description in the specification are only preferred examples of the present application, and are not used to limit the present application, various changes and improvements of the present application can be made without departing from the spirit and scope of the present application, and these changes and improvements all fall within the scope of the present application.
