Description

Technical Field

[0001] This utility model relates to the field of electric charging station technology, specifically to a water curtain fire isolation component for electric vehicle charging stations. Background Technology

[0002] As the electric vehicle market continues to expand, its safety issues are receiving increasing attention. The battery system of electric vehicles is a major source of fire risk. Lithium batteries may experience thermal runaway under conditions such as overheating, overcharging, or short circuits, leading to fires. Moreover, electric vehicle batteries have high energy density, so once a fire starts, it spreads rapidly. Unlike traditional gasoline vehicle fires, electric vehicle fires have higher combustion temperatures, reaching around 1000℃, and release large amounts of toxic and harmful gases such as carbon monoxide and hydrogen fluoride. These toxic gases not only cause serious damage to the vehicle itself but also pose a significant threat to the surrounding environment and the safety of people. Water curtains can be formed by spraying water evenly through nozzles to create a water curtain-like effect. In charging stations, when an electric vehicle catches fire, the water curtain can form an isolation zone around the vehicle, effectively suppressing the spread of the fire.

[0003] Chinese Utility Model Patent Publication No. CN 221332553 U discloses a fire extinguishing system for electric vehicle charging stations. This system can spray carbon dioxide gas from bottom to top immediately. The vaporized carbon dioxide gas can not only quickly cool the area around the electric vehicle, but also isolate oxygen, thereby suppressing the fire. Fire-fighting balls spray dry powder from top to bottom to cover the flames, quickly extinguishing the fire without reacting with the battery. This makes the fire extinguishing faster and safer. However, although this fire extinguishing system uses carbon dioxide gas for isolation, it is not easy to form an isolation curtain during use, which can easily lead to poor fire isolation effect. In addition, the cost of carbon dioxide gas is relatively high, resulting in poor promotion. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a water curtain fire isolation component for electric vehicle charging stations. It can effectively solve the problems of existing technologies, which use carbon dioxide gas for isolation, but are not easy to form an isolation curtain during use, resulting in poor fire isolation effect, and the high cost of carbon dioxide gas, which leads to poor promotion.

[0005] The technical solution adopted by this utility model is: a water curtain fire isolation component for electric vehicle charging stations, including a car charging station mounting frame, charging piles, and parking spaces. A support frame is fixedly installed on the outer surface of the car charging station mounting frame, and a top plate is fixedly installed on the other end of the support frame away from the car charging station mounting frame. A parking baffle is fixedly installed on the end of the parking space near the car charging station mounting frame. A water inlet pipe is provided on the outer surface of the car charging station mounting frame, and a main connecting pipe is fixedly installed on the other end of the water inlet pipe. A fixing frame is fixedly installed on the outer surface of the car charging station mounting frame. A secondary connecting pipe communicating with the main connecting pipe is provided on the outer surface of the main connecting pipe. A water outlet pipe communicating with the secondary connecting pipe is provided on the outer surface of the secondary connecting pipe, and a nozzle assembly is threadedly connected to the other end of the water outlet pipe away from the secondary connecting pipe. A limit component is provided on the outer surface of the main connecting pipe, and a solenoid valve is provided on the end of the secondary connecting pipe near the main connecting pipe.

[0006] Preferably, the nozzle assembly includes a connecting sleeve, a connecting seat is fixedly installed on the outer surface of the connecting sleeve, a connecting column is fixedly installed at the other end of the connecting seat away from the connecting sleeve, and a flow divider is fixedly installed at the other end of the connecting column away from the connecting seat. The connecting sleeve and the connecting seat are connected and located on the center line of the flow divider.

[0007] Through the above technical solution, when fire water enters the main connecting pipe from the inlet pipe, then flows into the auxiliary connecting pipe and the outlet pipe, it enters the sprinkler assembly through the connecting sleeve. The fixed connection between the connecting sleeve and the connecting seat, as well as its relative position to the diversion block, ensures that the water flow enters the diversion block stably. This makes the sprinkler assembly structure more stable, reduces shaking or damage caused by water flow impact, and ensures that fire water can be continuously and stably delivered to the diversion block for subsequent diversion operations, thereby improving the reliability of water curtain formation.

[0008] Preferably, the outer surface of the diversion block is provided with a diversion groove one and a diversion groove two, and a base plate is fixedly installed at the other end of the diversion block away from the connecting column. Multiple identical water outlet pipes and nozzle assemblies are provided, and the multiple water outlet pipes and nozzle assemblies are distributed at equal intervals.

[0009] Through the above technical solution, after the water flows into the diversion block, it will be diverted along diversion channel one and diversion channel two, and then evenly sprayed out from the nozzle assembly to form a water curtain. Multiple equidistantly distributed water outlet pipes and nozzle assemblies can fully cover the parking area, enabling the water curtain to be evenly distributed around the electric vehicle, providing fire isolation without blind spots. Both flames and toxic and harmful gases can be effectively blocked and suppressed, improving the fire isolation effect and minimizing the impact of fire on surrounding vehicles and the environment.

[0010] Preferably, the limiting component includes a limiting seat and an upper fixing sleeve. A lower fixing sleeve is fixedly installed on the outer surface of the limiting seat. A slot is opened at the other end of the lower fixing sleeve away from the limiting seat. A positioning bolt is threadedly connected to the outer surface of the lower fixing sleeve. A limiting groove is opened on the outer surface of the upper fixing sleeve.

[0011] With the above technical solution, when installing the main connecting pipe and the auxiliary connecting pipe, first place the main connecting pipe or the auxiliary connecting pipe in the groove of the lower fixing sleeve, and then fix the position initially by rotating the positioning bolt. Next, align the upper fixing sleeve with the lower fixing sleeve so that the main connecting pipe or the auxiliary connecting pipe is located in the limiting groove. This allows for quick and accurate positioning and initial fixing of the connecting pipe, improving installation efficiency and effectively preventing displacement of the connecting pipe during daily use or under external force, thus ensuring the stability of the entire fire water supply pipeline.

[0012] Preferably, a threaded post is fixedly installed at the other end of the upper fixing sleeve near the lower fixing sleeve, and a nut is threaded onto the outer surface of the threaded post.

[0013] Through the above technical solution, after the upper and lower fixed sleeves are connected, the connection between the upper and lower fixed sleeves can be further tightened by rotating the nut on the threaded column. This enhances the fixing effect of the limiting component on the main connecting pipe and the auxiliary connecting pipe, making the connection more secure and reliable. It avoids loosening of the connection due to long-term use or vibration, ensures the normal transportation of fire water in the pipeline, and maintains the normal operation of the water curtain fire isolation component.

[0014] Preferably, a partition plate one is inserted and installed on the inner surface of the slot, a partition plate two is provided on the outer surface of the fixed frame, and multiple identical limiting components are provided, with each limiting component being adapted to the main connecting pipe and the secondary connecting pipe respectively.

[0015] Through the above technical solution, when installing the limiting components, inserting the partition into the slot can isolate the main connecting pipe and the secondary connecting pipe in separate areas, preventing mutual interference between pipes. Multiple matching limiting components can effectively fix and isolate connecting pipes at different positions, improving the safety and stability of the entire fire protection pipeline system. It also facilitates the maintenance and repair of individual pipes or local areas, reducing the risk that a single fault will affect the operation of the entire water curtain fire isolation component.

[0016] Preferably, the cross-section of the secondary connecting pipe is L-shaped, and the two secondary connecting pipes form a group and are located directly above the parking space.

[0017] Through the above technical solution, when the fire protection system is running, the water flow enters the "L"-shaped secondary connecting pipe from the main connecting pipe, and can smoothly turn and deliver the water to the sprinkler assembly through the outlet pipe. The two secondary connecting pipes are designed as a group located directly above the parking space, which allows the sprinkler assembly to cover the parking space with a water curtain from different directions. This optimizes the delivery path of the fire water, improves the coverage effect and uniformity of the water curtain in the parking space area, better achieves fire isolation protection for electric vehicles, and reduces the possibility of fire spread.

[0018] Compared with the prior art, this utility model provides a water curtain fire isolation component for electric vehicle charging stations, which has the following beneficial effects:

[0019] 1. This electric vehicle charging station uses a water curtain fire isolation component. The connecting sleeve, connecting seat, and diversion block work together to ensure a stable water flow and even distribution through the diversion channel. Combined with multiple equally spaced water outlet pipes and nozzle components, a water curtain barrier is constructed in the parking area. It can effectively block and suppress flames and toxic and harmful gases in electric vehicle fires, significantly improve the fire isolation effect, minimize the negative impact of fire on surrounding vehicles, personnel, and the environment, effectively curb the spread of fire, provide a solid guarantee for the fire safety of the charging station, and reduce the cost of use through the water curtain.

[0020] 2. This electric vehicle charging station uses a water curtain fire isolation component. The initial positioning and fixing are achieved through the slot and positioning bolt of the lower fixing sleeve, and the final tightening is completed with the cooperation of the limiting groove and threaded post and nut of the upper fixing sleeve. This not only makes the installation process fast and efficient, but also accurately determines the position of the pipeline and effectively prevents its displacement. At the same time, the partition plate 1 in the slot and the partition plate 2 on the fixed frame cooperate with each other to isolate different pipelines, which improves the safety, stability and maintainability of the entire fire pipeline system.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Example 1: As Figure 1-8 As shown, the present invention provides a water curtain fire isolation component for an electric vehicle charging station, including a charging station mounting frame 1, a charging pile 4, and a parking space 5. A support frame 2 is fixedly installed on the outer surface of the charging station mounting frame 1, and a top plate 3 is fixedly installed on the other end of the support frame 2 away from the charging station mounting frame 1. A parking baffle 6 is fixedly installed on the end of the parking space 5 near the charging station mounting frame 1. A water inlet pipe 7 is provided on the outer surface of the charging station mounting frame 1, and a main connecting pipe 8 is fixedly installed on the other end of the water inlet pipe 7. A fixing frame 9 is fixedly installed on the outer surface of the charging station mounting frame 1. A secondary connecting pipe 10 communicating with the main connecting pipe 8 is provided on the outer surface of the secondary connecting pipe 10, and a water outlet pipe 11 communicating with the secondary connecting pipe 10 is provided on the outer surface of the secondary connecting pipe 10. A nozzle assembly 12 is threadedly connected to the other end of the water outlet pipe 11 away from the secondary connecting pipe 10. A limit assembly 14 is provided on the outer surface of the main connecting pipe 8, and a solenoid valve 16 is provided on the end of the secondary connecting pipe 10 near the main connecting pipe 8.

[0032] Specifically, the sprinkler assembly 12 includes a connecting sleeve 1201, a connecting seat 1202 is fixedly installed on the outer surface of the connecting sleeve 1201, a connecting column 1203 is fixedly installed at the other end of the connecting seat 1202 away from the connecting sleeve 1201, and a diverter block 1204 is fixedly installed at the other end of the connecting column 1203 away from the connecting seat 1202. The connecting sleeve 1201 and the connecting seat 1202 are connected and located on the center line of the diverter block 1204. The advantage is that when fire water enters the main connecting pipe 8 from the inlet pipe 7 and then flows into the auxiliary connecting pipe 10 and the outlet pipe 11, it will enter the interior of the sprinkler assembly 12 through the connecting sleeve 1201. The fixed connection between the connecting sleeve 1201 and the connecting seat 1202, as well as their relative positional relationship with the diversion block 1204, ensures that the water flow enters the diversion block 1204 stably. This makes the structure of the nozzle assembly 12 more stable, reduces the shaking or damage caused by water flow impact, and ensures that fire water can be continuously and stably delivered to the diversion block 1204 for subsequent diversion operations, thereby improving the reliability of water curtain formation.

[0033] Specifically, the outer surface of the diversion block 1204 is provided with diversion groove one 1205 and diversion groove two 1206. A base plate 1207 is fixedly installed at the other end of the diversion block 1204 away from the connecting column 1203. Multiple identical water outlet pipes 11 and nozzle assemblies 12 are provided, and these multiple water outlet pipes 11 and nozzle assemblies 12 are equidistantly distributed. The advantage is that after the water enters the diversion block 1204, it will be diverted along diversion groove one 1205 and diversion groove two 1206, and then evenly sprayed out from the nozzle assembly 12 to form a water curtain. Multiple equidistantly distributed water outlet pipes 11 and nozzle assemblies 12 can fully cover the parking space 5 area, enabling the water curtain to be evenly distributed around the electric vehicle, providing fire isolation without blind spots. Both flames and toxic or harmful gases can be effectively blocked and suppressed, improving the fire isolation effect and minimizing the impact of a fire on surrounding vehicles and the environment.

[0034] Specifically, the limiting component 14 includes a limiting seat 1401 and an upper fixing sleeve 1405. A lower fixing sleeve 1402 is fixedly installed on the outer surface of the limiting seat 1401. A slot 1403 is opened at the other end of the lower fixing sleeve 1402 away from the limiting seat 1401. A positioning bolt 1404 is threadedly connected to the outer surface of the lower fixing sleeve 1402. A limiting groove 1406 is opened on the outer surface of the upper fixing sleeve 1405. The advantage is that when installing the main connecting pipe 8 and the auxiliary connecting pipe 10, the main connecting pipe 8 or the auxiliary connecting pipe 10 can be connected first. Pipe 10 is placed in the slot 1403 of the lower fixing sleeve 1402, and then its position is initially fixed by rotating the positioning bolt 1404. Next, the upper fixing sleeve 1405 is connected to the lower fixing sleeve 1402, so that the main connecting pipe 8 or the auxiliary connecting pipe 10 is located in the limiting groove 1406. This allows for quick and accurate positioning and initial fixing of the connecting pipe, improving installation efficiency and effectively preventing displacement of the connecting pipe during daily use or under external force, thus ensuring the stability of the entire fire water supply pipeline.

[0035] Example 2: Figure 2-8 As shown, this is an improvement on the previous embodiment.

[0036] Specifically, a threaded post 1407 is fixedly installed at the other end of the upper fixed sleeve 1405 near the lower fixed sleeve 1402. A nut 1408 is threaded onto the outer surface of the threaded post 1407. The advantage is that after the upper fixed sleeve 1405 and the lower fixed sleeve 1402 are connected, the connection between the upper fixed sleeve 1405 and the lower fixed sleeve 1402 can be further tightened by rotating the nut 1408 on the threaded post 1407. This enhances the fixing effect of the limiting component 14 on the main connecting pipe 8 and the auxiliary connecting pipe 10, making the connection more secure and reliable. It avoids loosening of the connection due to long-term use or vibration, ensuring the normal transportation of fire water in the pipeline and maintaining the normal operation of the water curtain fire isolation component.

[0037] Specifically, a partition 13 is inserted and installed on the inner surface of the slot 1403, and a partition 2 15 is provided on the outer surface of the fixing frame 9. Multiple limiting components 14 are provided, and the multiple limiting components 14 are adapted to the main connecting pipe 8 and the auxiliary connecting pipe 10 respectively. The advantage is that when installing the limiting components 14, the partition 13 is inserted into the slot 1403, which can isolate the main connecting pipe 8 and the auxiliary connecting pipe 10 in separate areas to prevent mutual interference between pipes. Multiple adapted limiting components 14 can effectively fix and isolate the connecting pipes at different positions, improve the safety and stability of the entire fire protection pipeline system, facilitate the maintenance and repair of individual pipes or local areas, and reduce the risk of affecting the operation of the entire water curtain fire isolation component due to a failure in one place.

[0038] Specifically, the secondary connecting pipe 10 has an "L"-shaped cross-section. The two secondary connecting pipes 10 are grouped together and located directly above the parking space 5. The advantage is that when the fire protection system is running, after the water flows from the main connecting pipe 8 into the "L"-shaped secondary connecting pipe 10, it can smoothly turn and deliver the water to the sprinkler assembly 12 through the outlet pipe 11. The design of the two secondary connecting pipes 10 being grouped together and located directly above the parking space 5 allows the sprinkler assembly 12 to cover the parking space 5 with a water curtain from different directions, optimizing the fire water delivery path, improving the coverage effect and uniformity of the water curtain in the parking space 5 area, better achieving fire isolation protection for electric vehicles, and reducing the possibility of fire spread.

[0039] Working principle: During use, when fire water enters the main connecting pipe 8 from the inlet pipe 7, and then flows into the auxiliary connecting pipe 10 and the outlet pipe 11, it enters the sprinkler assembly 12 through the connecting sleeve 1201. The fixed connection between the connecting sleeve 1201 and the connecting seat 1202, as well as its relative position to the diversion block 1204, ensures that the water flow enters the diversion block 1204 stably. This makes the structure of the sprinkler assembly 12 more stable, reduces shaking or damage caused by water flow impact, and ensures that the fire water can be continuously and stably delivered to the diversion block 1204 for subsequent diversion operations, improving the reliability of water curtain formation. After entering the diversion block 1204, the water flow is diverted along the first diversion channel 1205 and the second diversion channel 1206, and then evenly sprayed out from the sprinkler assembly 12 to form a water curtain.Multiple equidistantly distributed water outlet pipes 11 and nozzle assemblies 12 can fully cover the parking space 5 area, enabling the water curtain to be evenly distributed around the electric vehicle, providing fire isolation without blind spots. Both flames and toxic or harmful gases can be effectively blocked and suppressed, improving the fire isolation effect and minimizing the impact of fire on surrounding vehicles and the environment. When installing the main connecting pipe 8 and the auxiliary connecting pipe 10, first place the main connecting pipe 8 or the auxiliary connecting pipe 10 into the slot 1403 of the lower fixing sleeve 1402, then initially fix the position by rotating the positioning bolt 1404, and then install the upper fixing sleeve 140... 5. The upper fixing sleeve 1405 aligns with the lower fixing sleeve 1402, positioning the main connecting pipe 8 or the auxiliary connecting pipe 10 within the limiting groove 1406. This allows for quick and accurate positioning and initial fixing of the connecting pipe, improving installation efficiency and effectively preventing displacement of the connecting pipe during daily use or under external force, ensuring the stability of the entire fire water supply pipeline. After aligning the upper fixing sleeve 1405 with the lower fixing sleeve 1402, rotating the nut 1408 on the threaded post 1407 further tightens the connection between the upper fixing sleeve 1405 and the lower fixing sleeve 1402, enhancing the limiting assembly 14's control over the main connecting pipe 8 and the auxiliary connecting pipe 10. The fixing effect of the connecting pipe 10 makes the connection more secure and reliable, avoiding loosening due to long-term use or vibration, ensuring the normal delivery of fire water in the pipeline, and maintaining the normal operation of the water curtain fire isolation component. When installing the limiting component 14, inserting the partition 13 into the slot 1403 can isolate the main connecting pipe 8 and the auxiliary connecting pipe 10 in separate zones, preventing mutual interference between pipes. Multiple matching limiting components 14 can effectively fix and isolate connecting pipes at different positions, improving the safety and stability of the entire fire pipeline system and facilitating maintenance of individual pipes or local areas. Maintenance reduces the risk of a single malfunction affecting the operation of the entire water curtain fire isolation component. When the fire protection system is running, the water flow enters the "L"-shaped secondary connecting pipe 10 from the main connecting pipe 8, and can then smoothly turn and be delivered to the sprinkler assembly 12 through the outlet pipe 11. The two secondary connecting pipes 10 are designed as a group located directly above the parking space 5, which allows the sprinkler assembly 12 to cover the parking space 5 with a water curtain from different directions. This optimizes the delivery path of the fire water, improves the coverage effect and uniformity of the water curtain in the parking space 5 area, better achieves fire isolation protection for electric vehicles, and reduces the possibility of fire spread.
