Description

Technical Field

[0001] This invention relates to the field of charging pile technology, and in particular to a new energy charging pile with a fire-fighting structure. Background Technology

[0002] With the rapid development of the new energy vehicle industry, charging piles, as core supporting facilities, are seeing continuous expansion in their deployment scale and application scenarios, leading to increasing attention to their safe operation. During prolonged high-power charging, the internal electrical components of charging piles are prone to overheating due to overload, short circuits, aging, and other factors, potentially causing fires. Furthermore, since charging piles are often located outdoors or in densely populated public areas, a fire could not only damage the charging pile equipment itself but also trigger a chain reaction, threatening the safety of surrounding people and property.

[0003] Most existing new energy charging piles rely solely on simple physical protection through their casings. Even those equipped with fire-fighting devices exhibit significant deficiencies in their fire protection structures: First, the fire-fighting components are often independently externally designed, limiting the range of the extinguishing agent and making it difficult to accurately cover the core heat-generating area of ​​the charging pile. Second, there is a lack of a coordinated protection mechanism after a fire is triggered. Even with fire-fighting devices, it's impossible to simultaneously block airflow between the inside and outside of the enclosure; the continuous supply of oxygen reduces fire-fighting efficiency, leading to a higher risk of fire spread. Third, the heat dissipation structure and fire protection structure are independent; the heat dissipation windows used during normal operation cannot be closed in time during a fire, failing to assist in fire suppression and potentially becoming channels for fire to spread outwards. Furthermore, some charging piles with fire-fighting functions require manual intervention to activate the fire-fighting program, resulting in a long response delay and making it difficult to effectively handle fires in their early stages.

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0029] Reference Figures 1 to 6 As shown, the present invention provides a technical solution: a new energy charging pile with a fire-resistant structure, including a fire-resistant protective box 1, a box door 2, a heat dissipation window 3, a fire-resistant component 4, a switch-closed component 5, a charging pile body 6, and a charging gun; the box door 2 is movably connected to the fire-resistant protective box 1, the heat dissipation window 3 is opened on the side wall of the fire-resistant protective box 1, the charging pile body 6 is disposed inside the fire-resistant protective box 1, the charging gun is electrically connected to the charging pile body 6, the fire-resistant component 4 is installed on the top of the fire-resistant protective box 1 and communicates with the interior of the fire-resistant protective box 1, the switch-closed component 5 is disposed on the inner side of the fire-resistant protective box 1 and is arranged corresponding to the heat dissipation window 3, and the fire-resistant protective box 1 and the movably connected box door 2 form a fire-resistant protective box 1. The basic protective carrier provides physical protection for the main body 6 of the charging pile, and the heat dissipation window 3 on the side wall ensures the heat dissipation needs of the charging pile during daily operation, taking into account both equipment protection and heat dissipation compatibility. At the same time, the fire-fighting component 4 can quickly deliver fire extinguishing medium to the area of ​​the main body 6 of the charging pile in the event of a fire through the gas storage tank 402 installed on the top, the gas supply pipe 405 and the fire extinguishing pipe 406 attached to the inner wall of the box, so as to achieve precise and full-area fire-fighting coverage. Meanwhile, the switch sealing component 5 is arranged corresponding to the heat dissipation window 3, which can close the heat dissipation channel in the event of a fire, and form a relatively closed fire extinguishing space with the fire-fighting component 4, thereby improving fire extinguishing efficiency and blocking the path of fire spread.

[0030] Reference Figure 2 , Figure 3 and Figure 4As shown in this embodiment: the fire-fighting component 4 includes a mounting base 401, a gas storage tank 402, a gas inlet 403, a pressure gauge 404, a gas supply pipe 405, a fire extinguishing pipe 406, and an exhaust port 407; the gas storage tank 402 is installed on the top of the fire protection box 1 via the mounting base 401, the gas inlet 403 and the pressure gauge 404 are respectively located at the ends of the gas storage tank 402, one end of the gas supply pipe 405 is connected to the gas storage tank 402, and the other end is connected to the fire extinguishing pipe inside the fire protection box 1. Connected to 406, the exhaust ports 407 are distributed on the surface of the fire extinguishing pipe 406 and face the charging pile body 6. The fire extinguishing pipe 406 has a serpentine coil structure and is arranged close to the inner wall of the fire protection box 1. The charging gun passes through the side wall of the fire protection box 1 and extends to the outside. A seal is provided at the penetration point between the charging gun and the fire protection box 1. The gas storage tank 402 is installed on the top of the fire protection box 1 through the fixing seat 401, thus utilizing the unused space on the top of the box to complete the fire protection components. The integrated layout avoids the gas tank 402 occupying the installation space of the charging pile body 6 inside the box, improving the rationality of the structural layout. Secondly, the end setting of the gas inlet 403 and the pressure gauge 404 facilitates the replenishment of fire extinguishing medium and real-time monitoring of the pressure status of the gas tank 402, ensuring the reliability of the fire-fighting component 4 before activation. At the same time, the gas pipe 405 connects the gas tank 402 to the fire extinguishing pipe 406 inside the box. Combined with the serpentine coil structure and the fire extinguishing pipe 406 arranged close to the inner wall of the box, it can maximize the coverage of the fire extinguishing medium. With the exhaust port 407 facing the charging pile body 6, it can achieve precise and all-area fire extinguishing medium spraying to the heat-generating area of ​​the charging pile, improving the targeting and efficiency of fire response. In addition, the sealing element at the side wall of the box where the charging gun passes through can ensure the dustproof sealing of the box under normal conditions. In the event of a fire, it can further improve the airtightness of the box with the switch sealing component 5, reducing oxygen flow to assist in fire extinguishing.

[0031] Reference Figure 2 , Figure 5 and Figure 6As shown, specifically, the switch-closing assembly 5 includes a sealing frame 501, a guide groove 502, a guide block 503, and a sealing plate 504. The sealing frame 501 is fixed to the inside of the fire protection box 1 and corresponds to the heat dissipation window 3. The guide groove 502 is opened on the inner wall of the sealing frame 501. The guide block 503 is disposed on both sides of the sealing plate 504. The sealing plate 504 is slidably connected to the guide groove 502 through the guide block 503 to close the heat dissipation window 3. The switch-closing assembly 5 also includes a traction rope 505, a pulley A 506, and a pulley B 507. The pulley A 506 and pulley B 507 are respectively installed on the inner top of the fire protection box 1. One end of the traction rope 505 is connected to the sealing plate 504, and the other end passes around the pulley A 506 and pulley B 507 in sequence and extends to the outside of the fire protection box 1. The switch-closing assembly 5 also includes a sealing plug 508, a sealing cylinder 509, and a spring 510. The sealing cylinder 509 is fixed to the outside of the fire protection box 1, and the sealing plug 508 is slidably disposed on the sealing cylinder 509. Inside, one end of spring 510 is connected to sealing plug 508, and the other end is connected to the inner wall of sealing cylinder 509. The end of traction rope 505 away from sealing plate 504 is connected to sealing plug 508. The switch sealing assembly 5 also includes armature frame 511, electromagnetic switch 512, and photoelectric smoke sensor 513. Armature frame 511 is set at the end of sealing plug 508. Electromagnetic switch 512 is installed on the outside of sealing cylinder 509 and corresponds to armature frame 511. Photoelectric smoke sensor 513 is set on the inner wall of fire protection box 1, and photoelectric smoke sensor 513 is electrically connected to electromagnetic switch 512. First, sealing frame 501 and heat dissipation window 3 are fixed inside the box. Combined with the sliding connection structure of guide groove 502, guide block 503 and sealing plate 504, it not only ensures the accurate sealing fit of sealing plate 504 to heat dissipation window 3, but also improves the smoothness of sealing action through sliding cooperation, ensuring that the heat dissipation channel can be quickly blocked in case of fire. Second, pulley A and pulley B The arrangement of the sealing plate 504 on the inner side of the top of the box, in conjunction with the structure of the traction rope 505 connecting the sealing plate 504 and the outer sealing plug 508, realizes the steering of the driving path of the sealing plate 504 and the transmission of force, so that the external driving component can remotely control the action of the sealing plate 504 inside the box, thus optimizing the spatial layout of the components. At the same time, the combination of the sealing cylinder 509, the sealing plug 508 and the spring 510 provides the sealing plate 504 with the reset pre-tightening force, which can keep the heat dissipation window 3 open under normal conditions to ensure the heat dissipation of the charging pile. After a fire is triggered, it can work with the traction structure to quickly drive the sealing plate 504 to close. In addition, the electrical connection between the photoelectric smoke sensor 513 and the electromagnetic switch 512, combined with the corresponding arrangement of the armature frame 511 and the electromagnetic switch 512, realizes the automatic sensing of fire and the automatic triggering of the sealing action. The closure of the heat dissipation window 3 can be completed without manual intervention, improving the timeliness of fire response.

[0032] Working Principle: During normal operation, the fire protection box 1 provides physical protection for the charging pile body 6 inside through the movable door 2. The heat dissipation windows 3 on its side walls remain open to dissipate the heat generated during operation, ensuring stable equipment operation. Simultaneously, the fire-fighting component 4 is in a standby state. Operators can monitor the pressure of the extinguishing medium in the tank in real time through the pressure gauge 404 at the end of the gas tank 402, and replenish the extinguishing medium through the gas inlet 403 to ensure the reliability of the fire-fighting component 4. The charging gun maintains an electrical connection with the charging pile body 6 to meet normal charging requirements. The seal on the side wall of the fire protection box 1 serves as a dustproof seal; under the pre-tightening force of the spring 510, the sealing plate 504 of the switch sealing assembly 5 maintains the open state of the heat dissipation window 3 through the sliding cooperation between the guide block 503 and the inner guide groove 502 of the sealing frame 501, and the electromagnetic switch 512 and the armature frame 511 are in a separated state. The overall structure does not affect the normal use of the charging pile. When a fire occurs inside the fire protection box 1 due to a malfunction of the charging pile body 6, the photoelectric smoke sensor 513 on the inner side wall of the box will quickly detect the smoke signal and transmit the electrical signal to the electromagnetic switch 512. After the electromagnetic switch 512 is energized, it generates... The magnetic attraction of the armature frame 511 causes the sealing plug 508 to slide within the sealing cylinder 509 and stretch the spring 510. The sliding of the sealing plug 508, through the traction rope 505 that passes around pulleys A and B in sequence, pulls the sealing plate 504 to slide along the guide groove 502 until the sealing plate 504 completely seals the heat dissipation window 3, thereby blocking the airflow between the inside and outside of the box and reducing the oxygen content inside the box. At the same time as the heat dissipation window 3 is closed, the fire-fighting component 4 is activated, and the fire extinguishing medium in the gas storage tank 402 is transported through the gas supply pipe 405 to the serpentine fire extinguishing pipe 406 arranged against the inner side wall of the fire protection box 1, and then through the surface of the fire extinguishing pipe 406 toward the charging pile body 6. The exhaust port 407 sprays extinguishing media in a comprehensive and precise manner into the fire area to achieve rapid fire suppression. During this process, the seal at the charging gun penetration point cooperates with the closed heat dissipation window 3 to form a relatively sealed space inside the fire protection box 1, further improving fire suppression efficiency, preventing the fire from spreading outward, and ensuring the safety of the charging pile and the surrounding environment. After the fire is extinguished, the power supply to the electromagnetic switch 512 is cut off, its magnetic force disappears, and the rebound force of the spring 510 will push the sealing plug 508 to reset. Then, the traction rope 505 drives the sealing plate 504 to slide, so that the heat dissipation window 3 is reopened, and the equipment returns to the standby charging state of normal operation.
