Description

Technical Field

[0001] The present invention relates to the field of charging technology, and more particularly to a liquid-cooled charging station. Background Art

[0002] With the acceleration of urbanization, high-rise buildings are increasing, and the use of electric bicycles is becoming more and more prevalent. However, fires caused by charging electric bicycles at home are becoming increasingly common, posing a serious threat to residents' lives and property. According to statistics, fires caused by charging electric bicycles have been increasing year by year in recent years, with the main causes including battery aging, charger mismatches, and overloaded charging circuits. To prevent such safety incidents, more and more residential communities are banning electric bicycles from taking elevators to upper floors. This has reduced the risk of charging indoors to some extent, but it has also created inconvenience for residents charging within the community.

[0003] Community charging stations have emerged to meet residents' charging needs. However, a serious safety hazard currently common in these stations is excessive line temperatures during centralized charging. This is due to the simultaneous charging of multiple e-bikes, which results in excessive line current and heat generation. When this heat cannot be dissipated promptly, the line temperature continues to rise, accelerating line aging, degrading insulation performance, and easily causing short circuits, which can lead to fires. Furthermore, traditional charging stations primarily rely on natural heat dissipation or simple air cooling systems, which have limited efficiency and are unable to meet the cooling needs of large numbers of e-bikes charging simultaneously. Therefore, developing a liquid-cooled charging station that can effectively address the problem of excessive line temperatures during centralized charging is of great significance for improving community charging safety and protecting residents' lives and property. In light of this, we propose a liquid-cooled charging station. Summary of the Invention

DETAILED DESCRIPTION

[0032] like Figures 1 to 12 As shown, the present invention relates to a liquid-cooled charging station, comprising a canopy 1, a charging bracket 2 is provided inside the canopy 1, a carrying frame 3 is connected to the back of the charging bracket 2, charging sockets 4 are linearly and evenly spaced on the front of the charging bracket 2, a framing mechanism 5 is provided below the charging sockets 4 on the charging bracket 2, a extinguishing mechanism 6 is provided inside the framing mechanism 5, a water storage mechanism 7 is provided on the carrying frame 3, a circulation pipeline 8 is connected to the water storage mechanism 7, the end of the circulation pipeline 8 away from the water storage mechanism 7 is connected to the charging bracket 2, and the bottom end of the circulation pipeline 8 also passes through the framing mechanism 5 and is connected to the extinguishing mechanism 6; The extinguishing mechanism 6 includes a bend 601 and a extinguishing head 602. The bend 601 is connected to the inner wall of the frame mechanism 5 and is connected to the circulation pipeline 8. The extinguishing heads 602 are arranged on the bend 601 in a U shape and at equal intervals. The extinguishing head 602 has a direct injection fire extinguishing state and a mist dispersion fire extinguishing state. In the direct injection fire extinguishing state, it extinguishes the fire at the root of the fire source and retards the fire from the source. In the mist dispersion fire extinguishing state, it expands the fire extinguishing area and prevents the spread of fire.

[0033] In this invention, the canopy 1 provides protection for the entire structure. The charging socket 4 on the charging bracket 2 is used to connect to an electric bicycle charger, meeting the needs of centralized charging. The support frame 3 supports the water storage mechanism 7. The water in the water storage mechanism 7 flows through the system through the circulation pipeline 8. On the one hand, it can cool the charging bracket 2 and surrounding circuits, alleviating the problem of excessive circuit temperatures caused by centralized charging. On the other hand, the circulation pipeline 8 transports the water to the fire extinguishing mechanism 6 within the frame mechanism 5, providing a water source for the fire extinguishing function.

[0034] When a fire occurs, the elbow 601 in the extinguishing mechanism 6 directs the water transported by the circulation pipeline 8 to the extinguishing head 602. To extinguish the fire at the root, the extinguishing head 602 switches to the direct injection mode, precisely spraying the concentrated water flow to the root of the fire, blocking the combustion at the source. To expand the fire extinguishing range to prevent the spread of the fire, the extinguishing head 602 switches to the mist dispersion mode, spreading the water mist to cover a larger area and achieving rapid fire control. The framing mechanism 5 forms a certain enclosure around the extinguishing mechanism 6 and the fire extinguishing area, improving fire extinguishing efficiency.

[0035] In an embodiment of the present invention, the extinguishing head 602 includes a connecting pipe 6021, a mother-and-child ring 6022, a rotating groove 6023, a slide 6024, an inner gear ring 6025, a rack 6026, a gear 6027 and a split nozzle 6028. The connecting pipe 6021 is arranged in a U-shaped and evenly spaced manner on the curved pipe 601. The mother-and-child ring 6022 is fixedly sleeved on the end of the connecting pipe 6021 away from the curved pipe 601. The rotating groove 6023 is opened at the mother-and-child ring 6022 near the curved pipe 60 At one end, rotating grooves 6023 are provided in an annular shape and at equal intervals on the parent-child ring 6022. An inner gear ring 6025 is rotatably provided on the rotating groove 6023. A rack 6026 is movably inserted into the sliding groove 6024. A gear 6027 is rotatably provided in an annular shape and at equal intervals on the parent-child ring 6022. One end of the gear 6027 is meshedly connected to the inner gear ring 6025, and the other end of the gear 6027 is meshedly connected to the rack 6026. A split nozzle 6028 is fixedly provided on the rack 6026.

[0036] When the extinguishing head 602 of the present invention is in operation, the connecting pipe 6021 serves as a water transport channel, directing the water in the elbow 601 into the inner portion of the parent-child ring 6022. The parent-child ring 6022 provides a mounting and support base for various components. When the state of the split nozzle 6028 needs to be adjusted, the inner gear ring 6025 rotates within the rotation groove 6023. Since one end of the gear 6027 meshes with the inner gear ring 6025, the rotation of the inner gear ring 6025 drives the synchronous rotation of the gear 6027. Since the other end of the gear 6027 meshes with the rack 6026, which is movably inserted into the chute 6024, the rotation of the gear 6027 is converted into the linear movement of the rack 6026 along the chute 6024. The split nozzle 6028 adjusts its position or posture as the rack 6026 moves, thereby changing the angle and range of water spraying to adapt to the needs of direct injection fire extinguishing or mist dispersion fire extinguishing. Finally, the water is sprayed out in a corresponding form through the split nozzle 6028 to achieve the fire extinguishing function.

[0037] In an embodiment of the present invention, an electric push rod 6029 is further provided on the outer wall of the parent-child ring 6022 , and an output end of the electric push rod 6029 is connected to one of the racks 6026 .

[0038] In the present invention, when the electric push rod 6029 is activated, its output end drives one of the connected racks 6026 to move linearly along the chute 6024. Because this rack 6026 meshes with the gear 6027, its movement drives the gear 6027 to rotate. The other end of the gear 6027 meshes with the inner ring gear 6025. The rotation of the gear 6027, in turn, drives the inner ring gear 6025 to rotate synchronously within the rotation groove 6023. The rotation of the inner ring gear 6025, in turn, drives the remaining racks 6026 to move synchronously along their corresponding chute 6024 through the transmission action of the other gears 6027. Ultimately, the split nozzles 6028 on all the racks 6026 can be adjusted in a coordinated manner to meet different firefighting requirements.

[0039] In an embodiment of the present invention, a spiral groove 6031 is opened on the inner wall of the split nozzle 6028, and a diffusion groove 6032 is opened on the side wall of the split nozzle 6028. Several spiral grooves 6031 are combined to form a spiral direct injection channel, and the diffusion groove 6032 is conical in shape to form a mist dispersion channel.

[0040] In the present invention, when water enters the split nozzle 6028, if direct injection fire extinguishing is required, the spiral direct injection channel composed of several spiral grooves 6031 will guide the water flow along the spiral trajectory, so that the water flow converges to form a concentrated and directional impact direct water flow, which can accurately act on the fire source area; if mist dispersion fire extinguishing is required, the conical diffusion groove 6032 will guide the water flow to diffuse in all directions when passing through, forming a mist water flow with a wider coverage area, thereby meeting the requirements for water flow form in different fire extinguishing scenarios.

[0041] In an embodiment of the present invention, the canopy 1 includes a water collecting top plate 101, pillars 102, a collection trough 103 and a bottom pipe 104. Several pillars 102 are installed on the ground. The water collecting top plate 101 is arranged on the pillars 102. The front and both sides of the water collecting top plate 101 are folded upward, and the back of the water collecting top plate 101 is folded downward. The collection trough 103 is arranged on the back of the water collecting top plate 101. The bottom pipe 104 is connected to the bottom end of the collection trough 103 and is connected to it. The bottom end of the bottom pipe 104 is connected to the water storage mechanism 7.

[0042] When the canopy 1 of the present invention is in operation, the pillars 102 are installed on the ground, providing stable support for the entire canopy structure and bearing the weight of the water collection top plate 101. The back of the water collection top plate 101 is folded downward, which facilitates the guidance of rainwater falling on the top plate to the back for collection. The rainwater collected on the back of the water collection top plate 101 flows into the confluence trough 103 provided there, which plays a role in collecting and concentrating the rainwater. The rainwater is then transported downward through the bottom pipe 104 connected to it, and finally introduced into the water storage mechanism 7 from the bottom end of the bottom pipe 104, realizing the collection and utilization of rainwater, and providing water source supplement for the water circulation and fire extinguishing functions of the entire system.

[0043] In an embodiment of the present invention, the framing mechanism 5 includes a base plate 501 and a framing frame 502. The base plate 501 is installed on the ground directly below the canopy 1. The framing frame 502 is linearly and evenly spaced on the base plate 501. The framing frame 502 is located at the bottom end of the charging socket 4. The extinguishing mechanism 6 is provided on the inner wall of the framing frame 502. The framing frame 502 is in the shape of an elliptical hemisphere.

[0044] In the present invention, the base plate 501 is mounted on the ground directly below the canopy 1, providing a stable mounting base for the entire framing mechanism and ensuring that the structure is not easily shaken during use. The linearly and evenly spaced framing frames 502 on the base plate 501 correspond to the positions of the charging sockets 4, forming an enclosed area for the e-bikes docked under the corresponding charging sockets, thus framing the space. This structure naturally limits the number of parking spaces at the charging station. The space corresponding to each framing frame 502 can only accommodate one e-bike for docking and charging. The linear and evenly spaced arrangement clearly defines the number of vehicles that can be docked in a single row. This limiting effect brings multiple effects: on the one hand, it avoids excessive concentration of vehicles due to disorderly parking, reduces mutual obstruction between vehicles, and ensures that when a fire occurs, the water flow and water mist of the extinguishing mechanism 6 in the direct injection extinguishing or mist dispersion extinguishing state can effectively cover the target vehicle and surrounding area, reducing the risk of rapid spread of fire among densely packed vehicles; on the other hand, a reasonable parking quantity limit can ensure the ventilation conditions in the charging area, and cooperate with the liquid cooling function of the circulation pipeline 8 to further alleviate the problem of local excessive temperature caused by excessive concentration of vehicles during centralized charging, thereby improving the overall charging safety.

[0045] In addition, a fire extinguishing mechanism 6 is installed on the inner wall of the elliptical hemispherical frame 502. Its arc-shaped structure can guide the water flow or water mist sprayed by the fire extinguishing mechanism 6 to spread within the frame range, reduce the meaningless diffusion of the fire extinguishing medium to the outside, improve the utilization efficiency of the fire extinguishing medium, and at the same time form a certain barrier to the fire, thereby helping to improve the fire extinguishing effect.

[0046] As another embodiment of the present invention, the water storage mechanism 7 includes a water storage barrel 701, a water injection hole 702, a filter plate 703 and an impeller 704. The water storage barrel 701 is arranged on the supporting frame 3, the water injection hole 702 is arranged at the top of the water storage barrel 701, the top of the water injection hole 702 is connected to the bottom pipe 104, the filter plate 703 is arranged inside the water storage barrel 701, and the impeller 704 is rotatably arranged at the bottom end of the water storage barrel 701.

[0047] The water transported by the bottom pipe 104 in the present invention enters the water storage barrel 701 through the water injection hole 702 provided at the top thereof, thereby collecting and storing the water, and reserving water for the water circulation and fire extinguishing functions of the entire system.

[0048] When the water enters the water storage barrel 701, the internal filter plate 703 will filter the water, intercept impurities, particulate matter, etc. in the water, prevent impurities from entering the subsequent pipelines and causing blockages, and ensure the cleanliness of the water to meet usage requirements.

[0049] As another embodiment of the present invention, a circulation port A705 and a circulation port B706 are also provided on the water storage barrel 701. The circulation port A705 is opened at the top of the water storage barrel 701, and the circulation port B706 is opened at the bottom of the water storage barrel 701. The water inlet end of the circulation pipe 8 is connected to the circulation port B706, and the water outlet end of the circulation pipe 8 is connected to the circulation port A705.

[0050] In the present invention, the circulation port B706 at the bottom end of the water storage barrel 701 is connected to the water inlet end of the circulation pipeline 8, and the water stored in the barrel is transported to the circulation pipeline 8 to provide water flow for the system's liquid cooling and extinguishing mechanism 6; the water after flowing through the circulation pipeline 8 is transported to the circulation port A705 at the top end of the water storage barrel 701 through the water outlet end of the circulation pipeline 8, and then flows back into the water storage barrel 701, realizing the recycling of the water.

[0051] Impeller 704 in water storage tank 701 is driven by a built-in motor. As impeller 704 rotates, it generates a driving force on the water in the tank, forcing the water in the tank 701 into circulation line 8 through circulation port B 706. This force also pushes the water in circulation line 8, which has returned to the water storage tank 701, back into the tank, completing the water cycle.

[0052] As another embodiment of the present invention, the circulation pipeline 8 includes an inlet channel 801 and a return channel 802. The input end of the inlet channel 801 is connected to the circulation port B706, and the output end of the return channel 802 is connected to the circulation port A705. The inlet channel 801 and the return channel 802 are connected.

[0053] In the present invention, since the water inlet channel 801 and the return water channel 802 are interconnected, a closed circulation path is formed: the water transported by the water inlet channel 801 flows into the return water channel 802 through the connecting structure after flowing through the target area, and is then sent back to the water storage tank 701 by the return water channel 802, thereby realizing the recycling of water, which not only improves the utilization rate of water resources, but also ensures that the system can obtain a continuous water supply during liquid cooling or fire extinguishing.

[0054] As another embodiment of the present invention, a through hole 301 is opened on the supporting frame 3, and a supporting rod 302 is fixedly provided at the top of the through hole 301 in a circular shape with equal intervals. A cooling fan 303 is provided at the bottom of several supporting rods 302, and a water storage mechanism 7 is arranged on several supporting rods 302.

[0055] In the present invention, through-holes 301 in the support frame 3 provide passageways for air circulation. Ring-shaped support rods 302, fixed at equal intervals on the top, provide support, stably mounting the water storage mechanism 7 above the through-holes 301 and creating a certain gap between the water storage mechanism 7 and the support frame 3. When the cooling fan 303 at the bottom of the support rods 302 is in operation, it draws hot air from the periphery of the water storage mechanism 7 and expels it outward through the through-holes 301, while simultaneously encouraging the flow of cool air from the outside to the periphery of the water storage mechanism 7. This process accelerates heat exchange on the surface of the water storage mechanism 7, promptly dissipating heat generated by circulation or environmental factors, preventing rising water temperatures from affecting the liquid cooling effect and ensuring efficient heat dissipation and stable operation of the system.

[0056] Working Principle: This embodiment provides a liquid-cooled charging station. When in use, the water collection top plate 101 of the canopy 1 folds upward on the front and sides and downward on the back, directing rainwater to the confluence trough 103 on the back. The rainwater then enters the water storage mechanism 7 through the bottom pipe 104 and the water injection hole 702 at the top of the water storage barrel 701. The water is filtered for impurities by the filter plate 703 in the water storage barrel 701 and then stored, providing a clean water source for the system. The impeller 704 in the water storage barrel 701 is driven by a built-in motor, pushing the water into the water inlet channel 801 of the circulation pipeline 8 through the circulation port B706 at the bottom. The water absorbs heat when flowing through the charging bracket 2 and the surrounding circuits, achieving liquid cooling. It then flows back through the return channel 802 and the circulation port A705 at the top of the water storage barrel 701, forming a closed water cycle. The cooling fan 303 on the support frame 3 draws the hot air around the water storage mechanism 7 and discharges it through the through hole 301, accelerating the heat dissipation of the water and ensuring the liquid cooling effect. When a fire occurs, the circulation pipeline 8 transports water to the extinguishing mechanism 6 in the frame mechanism 5, and the bend pipe 601 guides the water flow into the connecting pipe 6021 of the extinguishing head 602; the electric push rod 6029 pushes the rack 6026 to move along the slide groove 6024, and drives the inner gear ring 6025 to rotate in the rotating groove 6023 through the gear 6027, so that the split nozzles 6028 on all the racks 6026 adjust their postures synchronously. In the direct injection fire extinguishing state, the spiral grooves 6031 on the inner wall of the split nozzle 6028 form a spiral direct injection channel, and the water flow is concentratedly sprayed to the root of the fire source; in the mist dispersion fire extinguishing state, the conical diffusion grooves 6032 on the side wall of the split nozzle 6028 form a mist dispersion channel, and the water mist spreads to cover a larger area to prevent the spread of the fire. The elliptical hemispherical frame 502 guides the water flow or water mist to spread in a limited area, reducing the waste of fire extinguishing medium, while forming a barrier to the fire and improving the fire extinguishing efficiency.

[0057] The embodiments disclosed in the present invention are preferred embodiments, but are not limited to them. Ordinary technicians in this field can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes. As long as they do not deviate from the spirit of the present invention, they are all within the scope of protection of the present invention.
