Description

Technical Field

[0001] The present invention relates to the technical field of new energy charging, and specifically to a wall-mounted charging pile structure. Background Art

[0002] With the popularization of new energy electric vehicles, the application scenarios of electric vehicles are becoming more and more extensive. As a result, the demand for charging piles has emerged. Wall-mounted charging piles, also known as wall-mounted intelligent AC charging piles, are auxiliary devices for charging new energy vehicles. Wall-mounted charging piles can be conveniently installed in various parking lots and outdoors, and have the characteristics of being convenient and compact. At the same time, with the support of the intelligence of the Internet of Things, various shared charging methods can be realized, which also provides the necessary conditions for commercial operation and has a broad market prospect. In the scenario of fire fighting for fires caused by potential reasons such as aging and faults of wall-mounted charging piles, most of them use the fire-fighting facilities at the site where the wall-mounted charging piles are located to detect fires, lacking the detection in the early stage of the fire. At the same time, after the fire occurs, because the charging gun is located on the side of the charging box, it is extremely easy to cause multiple ignition points to appear, which will further spread the fire and may lead to greater losses. Summary of the Invention

[0003] The purpose of the present invention is to provide a wall-mounted charging pile structure to solve the problems generated by the fire fighting of the existing wall-mounted charging piles on fire.

[0004] To achieve the above purpose, the present invention provides the following technical solutions: A wall-mounted charging pile structure includes a charging box, a fire-fighting module is arranged above the charging box, and a charging gun is connected to the bottom of the charging box through an electric wire. The fire-fighting module includes a placement box, a gas fire extinguisher, an air pipe, an air delivery guiding pipe, a heat-sensitive block, a connecting rope, an electricity isolation sheet, a connecting spring, a connection spring, a first sealing ring, a second sealing ring, a heat-sensitive ball and an alarm. A placement box is arranged above the charging box, a gas fire extinguisher is arranged in the placement box, one end of an air pipe is connected to the side of the gas fire extinguisher, and the other end of the air pipe passes through the side of the charging box and is arranged in the charging box. The other end of the air pipe is sleeved by the air delivery guiding pipe. A heat-sensitive ball is sleeved at the end of the air pipe far from the gas fire extinguisher. A first sealing ring is arranged between the heat-sensitive ball and the air pipe, and the first sealing ring is fitted to the connection between the air pipe and the heat-sensitive ball. A second sealing ring is arranged at the end of the air delivery guiding pipe far from the heat-sensitive ball, and the second sealing ring is sleeved on the outside of the air pipe. One end of a connecting rope is connected to the air delivery guiding pipe near the heat-sensitive ball, and the other end of the connecting rope passes through the top of the charging box and the placement box and is led out above the placement box to be connected to the alarm. An electricity isolation sheet is arranged between the connecting rope and the alarm for connection. One end of the gas transmission guiding pipe, which is away from the placement box on the outer side, is provided with a connecting slide rail. One end of a connecting spring is arranged on the side of the charging box close to the second sealing ring, and the other end of the connecting spring is slidably connected to the connecting slide rail. One end of a drain pipe is respectively arranged in the gas transmission guiding pipe and the air pipe. One end of a plurality of drain pipes is arranged at the contact surface between the gas transmission guiding pipe and the thermosensitive ball. The other end of the drain pipe passes through the gas transmission guiding pipe and leads to the side of the air pipe close to the second sealing ring. The drain pipe passes through the gas transmission guiding pipe and is communicated with the inside of the charging box. A thermosensitive block is connected between the outer side of the gas transmission guiding pipe and the top of the charging box.

[0005] Optionally, the outer side of the hook rope is sleeved with a hook spring. The hook spring is located inside the charging box and is connected to the top of the charging box.

[0006] Optionally, a blocking through hole is arranged at one end of the gas transmission guiding pipe connecting the thermosensitive ball, and the blocking through hole is connected to the thermosensitive ball.

[0007] Optionally, one end of the gas transmission guiding pipe connected with the blocking through hole is set to be arc-shaped, and the shape of one end of the gas transmission guiding pipe connected with the blocking through hole fits the shape of the thermosensitive ball.

[0008] Optionally, a detachment module is arranged on one side of the charging box away from the air pipe. The detachment module is obliquely arranged on the side of the charging box towards the direction away from the placement box. The detachment module is arranged on the side of the charging box away from the air pipe. The detachment module includes a connecting ring, a clamping block, a clamping spring, an airbag strip, and a storage pipe. The connecting ring is sleeved by the side of the charging box. One end of the storage pipe is coaxially sleeved with the connecting ring. The other end of the storage pipe is movably connected to the charging gun. A clamping groove is arranged on the outer side of the storage pipe. A plurality of clamping springs are circularly arranged at the clamping groove. Each clamping spring is connected with a clamping block. An airbag groove is arranged on the inner side of the connecting ring. An extraction through hole is arranged on the outer side of the connecting ring away from the placement box. Two ends of the extraction through hole are respectively connected with the airbag groove and the inside of the charging box. The airbag strip is arranged along the airbag groove around the outer side of the connecting ring. The airbag strip is led out from the extraction through hole to the inside of the charging box. The clamping block is controlled by the clamping spring to contact the airbag strip in the airbag groove, and the side surface of the clamping block is controlled to contact the side surface of the airbag groove.

[0009] Optionally, an airbag ball is arranged at one end of the airbag strip away from the connecting ring.

[0010] Optionally, the shape of the clamping block is arc-shaped, and each clamping block is coaxially arranged with the storage pipe.

[0011] Beneficial effects: 1. The gas transmission guiding pipe of the present invention can cooperate with the trachea. When the temperature in the charging box rises to a certain level, the liquid in the thermosensitive block and the thermosensitive ball expands due to heat, which will cause the thermosensitive block and the thermosensitive ball to rupture. Then, the gas in the gas fire extinguisher will be transported to the inside of the charging box through the trachea and the gas transmission guiding pipe. Then, the gas is used to extinguish the fire inside the charging box. At the same time, the rupture of the thermosensitive block causes the gas transmission guiding pipe to be controlled by the force generated by the deformation of the connecting spring. Then, the blocking through hole and the drain pipe of the gas transmission guiding pipe are blocked.

[0012] 2. The detachment module of the present invention is led out of the charging box to the outside of the charging box. The axis of the detachment module is inclined in a direction away from the placement box. The end of the storage pipe connected to the charging gun is closer to the ground. When a fire occurs in the charging box, the airbag ball is heated, causing the air in the airbag ball and the airbag strip to expand. Then, the airbag strip surrounding the airbag groove will occupy more space, and then apply pressure to all the clamping blocks, pushing the clamping spring to contract. When the clamping spring contracts to a certain position, the clamping block will be pushed out of the airbag groove. Then, the connection between the connecting ring and the storage pipe will be disconnected due to the loss of the nesting of the clamping block, and the storage pipe will drive the charging gun to detach from the charging box. This can effectively prevent the increase of the ignition point and avoid the spread of the fire outside the charging box, thus avoiding potential risks. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention. All other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0021] Please refer to Figures 1-6 , the present invention provides a wall-mounted charging pile structure, and the specific implementation plan is as follows: As Figures 1-4 shown, a wall-mounted charging pile structure includes a charging box 1, a fire protection module 2 is arranged above the charging box 1, and a charging gun 4 is connected to the bottom of the charging box 1 through an electric wire 5; The fire protection module 2 includes a placement box 21, a gas fire extinguisher 211, an air pipe 22, an air delivery guiding pipe 23, a thermal-sensitive block 24, a connecting rope 25, an electricity isolation sheet 251, a connecting spring 252, a connecting spring 26, a first sealing ring 221, a second sealing ring 231, a thermal-sensitive ball 234 and an alarm 252. A placement box 21 is arranged above the charging box 1. A gas fire extinguisher 211 is arranged inside the placement box 21. One end of an air pipe 22 is connected to the side of the gas fire extinguisher 211. The other end of the air pipe 22 passes through the side of the charging box 1 and is arranged inside the charging box 1. The other end of the air pipe 22 is sleeved by an air delivery guiding pipe 23. A thermal-sensitive ball 234 is sleeved at the end of the air pipe 22 far from the gas fire extinguisher 211. An arc-shaped blocking through hole 233 is arranged at the end of the air delivery guiding pipe 23 connected to the thermal-sensitive ball 234. The end of the air delivery guiding pipe 23 connected to the blocking through hole 233 fits the outer shape of the thermal-sensitive ball 234. One end of a connecting rope 25 is connected to the air delivery guiding pipe 23 near the thermal-sensitive ball 234. The other end of the connecting rope 25 passes through the top of the charging box 1 and the placement box 21 and extends above the placement box 21 to be connected to the alarm 252. An electricity isolation sheet 251 is arranged between the connecting rope 25 and the alarm 252 for connection. The connecting rope 25 is sleeved by a connecting spring 252 on the outside. The connecting spring 252 is located inside the charging box 1 and is connected to the top of the charging box 1; A first sealing ring 221 is arranged between the thermal-sensitive ball 234 and the air pipe 22. The first sealing ring 221 fits the connection part between the air pipe 22 and the thermal-sensitive ball 234. The first sealing ring 221 is connected to the air pipe 22 and the thermal-sensitive ball 234 to prevent gas from entering the inside of the charging box 1 through the gap between the air pipe 22 and the thermal-sensitive ball 234. A second sealing ring 231 is arranged at the end of the air delivery guiding pipe 23 far from the thermal-sensitive ball 234. The second sealing ring 231 is sleeved on the outside of the air pipe 22. The second sealing ring 231 is located between the outer side surface of the air pipe 22 and the air delivery guiding pipe 23 to seal between the air pipe 22 and the air delivery guiding pipe 23; A connecting slide rail 27 is arranged at a place on the outer side surface of the air delivery guiding pipe 23 far from the placement box 21. One end of a connecting spring 26 is arranged on the side of the charging box 1 near the second sealing ring 231. The other end of the connecting spring 26 is connected to a sliding piece. The sliding piece is slidably connected to the connecting slide rail 27. When the sliding piece slides, the connecting spring 26 slides in the sliding rail accordingly. When the air delivery guiding pipe 23 is connected to the charging box 1 through the thermal-sensitive block 24, the connecting spring 26 can slide in the connecting slide rail 27. One end of the connecting spring 26 will slide to a place with the smallest bending degree in the connecting slide rail 27, so as to reduce the bending degree of the connecting spring 26 to a certain extent and reduce the plastic deformation of the connecting spring 26; One end of a drain pipe 232 is respectively arranged inside an air delivery guiding pipe 23 and an air pipe 22. One end of a plurality of drain pipes 232 is arranged on the contact surface between the air delivery guiding pipe 23 and a thermal ball 234. The other end of the drain pipe 232 passes through the air delivery guiding pipe 23 and leads to a position near a second sealing ring 231 of the air pipe 22. A plurality of small holes are arranged between the outer side surface of the drain pipe 232 and the air delivery guiding pipe 23. The small holes are for gas to be led out from the contact surface between the air delivery guiding pipe 23 and the thermal ball 234 into the drain pipe 232 in the case of the rupture of the thermal ball 234, and then led into a charging box 1 through the small holes. A thermal block 24 is connected between the outer side surface of the air delivery guiding pipe 23 and the top end of the charging box 1 and is fixed to the charging box 1 through the thermal block 24. In case of a fire, the thermal block 24 is heated, and thus the liquid inside the thermal block 24 expands due to heat, causing the plastic outside the liquid to rupture, so that the whole thermal block 24 ruptures. The rupture of the whole thermal block 24 causes a connecting spring 26 to deform, and thus the force generated by the deformation of the connecting spring 26 is used to drive the air pipe 22 and the air delivery guiding pipe 23 to move towards the bottom of the charging box 1 inside the charging box 1. Furthermore, in the case that the liquid inside the thermal ball 234 expands due to heat, causing the plastic outside the liquid to rupture, and then the thermal ball 234 ruptures. At this time, the air pipe 22 can convey the gas with a fire extinguishing function inside a gas fire extinguisher 211 through a blocking through hole 233 and the small holes to the inside of the charging box 1, thus playing a role in alleviating the fire and extinguishing the initial fire; Meanwhile, when the air pipe 22 and the air delivery guiding pipe 23 move towards the bottom of the charging box 1, one end of the air delivery guiding pipe 23 connected with a hook-up rope 25 will be subjected to the force generated by the movement of the air pipe 22 and the air delivery guiding pipe 23 towards the bottom of the charging box 1. Then the other end of the hook-up rope 25 is subjected to force accordingly, thus controlling the separation of an electricity isolation sheet 251 and an alarm 252. When the air pipe 22 and the air delivery guiding pipe 23 start to move towards the bottom of the charging box 1 under the force generated by the deformation of the connecting spring 26 after the thermal block 24 ruptures, the hook-up spring 252 simultaneously generates a certain force due to deformation. Since the connecting spring 26 and the hook-up spring 252 start to deform simultaneously after the thermal block 24 ruptures, under the combined action of the connecting spring 26 and the hook-up spring 252, the air delivery guiding pipe 23 will not be attached to a certain surface of the charging box 1 due to the traction of a certain part of the connecting spring 26 and the hook-up spring 252. After the thermal block 24 ruptures, the air delivery guiding pipe 23 will swing to a certain extent due to the contraction of the connecting spring 26 and the stretching of the hook-up spring 252. Until the deformation of the connecting spring 26 and the hook-up spring 252 stops, the air delivery guiding pipe 23 will be inclined with respect to the bottom of the charging box 1. Then the gas overflowing from the surface of the air delivery guiding pipe 23 will cover a larger area inside the charging box 1, maximizing the fire extinguishing effect; After the electricity isolation sheet 251 is separated from the alarm 252, the circuit inside the alarm 252 is connected, and then the alarm 252 starts to work, and notifies people that a fire has occurred in the charging box 1 through the sound emitted by the alarm 252, which is convenient for the fire safety personnel to timely grasp the relevant situation of the fire.

[0022] As Figures 5-6 shown, a detachment module 3 is provided on the side of the charging box 1 away from the air pipe 22. The detachment module 3 gradually moves away from the placement box 21 from the end located inside the charging box 1 to the end located outside the charging box 1. The detachment module 3 is provided on the side of the charging box 1 away from the air pipe 22. The detachment module 3 includes a connection ring 31, a clamping block 32, a clamping spring 33, an airbag strip 34, and a storage pipe 35. The connection ring 31 is sleeved on the side of the charging box 1. One end of the storage pipe 35 is coaxially sleeved with the connection ring 31. The other end of the storage pipe 35 is movably connected to the charging gun 4. The axes of the connection ring 31 and the storage pipe 35 are arranged facing the ground. A clamping groove 351 is provided on the outer side of the storage pipe 35. A number of clamping springs 33 are circularly arranged at the clamping groove 351. Each clamping spring 33 is connected to a clamping block 32. The overall shape of the clamping block 32 is arc-shaped. Each clamping block 32 is circularly arranged around the storage pipe 35 coaxially. An airbag groove 311 is provided on the inner side of the connection ring 31. An extraction through hole 312 is provided on the outer side of the connection ring 31 away from the placement box 21. The two ends of the extraction through hole 312 are respectively connected to the airbag groove 311 and the inside of the charging box 1. The airbag strip 34 is arranged along the airbag groove 311 around the outer side of the connection ring 31. The airbag strip 34 is led out from the extraction through hole 312 to the inside of the charging box 1. An airbag ball 341 is provided at the end of the airbag strip away from the connection ring 31. The clamping block 32 is controlled by the clamping spring 33 to contact the airbag strip 34 in the airbag groove 311, and the side of the clamping block 32 is controlled 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 heat-expandable gas. The inside of the airbag ball 341 is communicated with the inside of the airbag strip 34. When a fire occurs, the airbag ball 341 is heated, and then the gas in the airbag ball 341 and the airbag strip 34 expands due to heat. Then the whole airbag strip 34 expands, and then each clamping block 32 is subjected to the force exerted by the airbag strip 34 and moves towards the direction close to the clamping spring 33. Then the clamping spring 33 contracts. Until the clamping block 32 completely exits the airbag groove 311, then the storage pipe 35 lacks the support of the connection ring 31, and then the storage pipe 35 together with the connected charging gun 4 is detached from the connection ring 31 and the charging box 1, which can avoid the charging gun 4 and the wire 5 at its connected end being affected by the fire in the case of the spread of the fire, and can effectively prevent the fire from getting out of control.

[0023] The working process of this embodiment is as follows: When a fire occurs inside the charging box 1, the temperature inside the charging box 1 rises. The increase in temperature causes the thermal-sensitive block 24 and the thermal-sensitive ball 234 to rupture. Immediately, the air pipe 22 and the air delivery guiding pipe 23 are deformed by the connecting spring 26 to contract and then move towards the bottom of the charging box 1. At the same time, the hook connecting rope 25 moves with the air delivery guiding pipe 23, and the hook connecting rope 25 will drive the electricity isolation sheet 251 away from the alarm 252. At the same time, the bottom end of the hook connecting spring 252 moves together with the hook connecting rope 25, and thus the hook connecting spring 252 is deformed by stretching. The connecting spring 26 and the hook connecting spring 252 jointly control the air delivery guiding pipe 23 to be inclined with the bottom surface of the charging box 1 in a form that does not fit the inner side 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 blockage of the thermal-sensitive ball 234, thereby extinguishing the fire at the ignition point inside the charging box 1; Synchronously with the rupture of the thermal-sensitive block 24 and the thermal-sensitive ball 234, the gas in the airbag ball 341 and the airbag strip 34 expands due to the heat received by the airbag ball 341. As a result, the clamping block 32 extending into the airbag groove 311 is pushed by the expanding volume of the airbag strip 34, causing the clamping spring 33 connected to the clamping block 32 to contract. Then, the clamping block 32 is pushed out of the airbag groove 311 by the airbag strip 34. Thus, the storage pipe 35 loses the support force provided by the connecting ring 31, and the storage pipe 35 together with the charging gun 4 slides in the axial direction of the connecting ring 31 towards the outside of the charging box 1.
