Description

Technical Field

[0001] This utility model relates to the field of charging pile technology, specifically to an AC charging pile with fire extinguishing function. Background Technology

[0002] Most AC charging stations on the market are currently installed in open-air environments, exposed to direct sunlight for extended periods, especially during the hot summer months. High temperatures accelerate the aging of internal cables, increasing the risk of fire. Furthermore, if a short circuit or external fire occurs at the AC charging station, existing designs often lack effective fire prevention measures, allowing the fire to spread easily and cause a larger-scale fire, resulting in significant economic losses and safety risks. Therefore, there is a need for an AC charging station with fire-extinguishing capabilities. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides an AC charging pile with fire extinguishing function, thus solving the technical problems mentioned in the background section.

[0004] The technical solution of this utility model is as follows: An AC charging pile with fire extinguishing function includes a charging pile, and a fire extinguishing component is provided on the top of the charging pile. The fire extinguishing component includes a liquid storage tank fixed on the top of the charging pile. The liquid storage tank is filled with fire extinguishing liquid. Several liquid flow holes penetrating through the inside and outside are opened on the inner walls of the four sides of the liquid storage tank. A heat-melting sealing block is fixed inside each of the several liquid flow holes.

[0005] In addition, an auxiliary extinguishing component is installed on top of the liquid storage tank to cooperate with the fire extinguishing component to expand the range of fire extinguishing.

[0006] Preferably, the auxiliary extinguishing component includes four hanging ears disposed on the top of the liquid storage tank. Each of the four hanging ears is formed by vertically welding a vertical plate and a horizontal plate. A piercing needle is fixed to the bottom of the horizontal plate. A filling ring is fixed to the outer wall of the liquid storage tank. Extinguishing powder is filled inside the filling ring. A power component is disposed inside the liquid storage tank to drive the piercing needle to move down and pierce the filling ring.

[0007] Preferably, the power unit includes a buoyancy pack floating on top of the extinguishing liquid, and the top of the buoyancy pack is provided with a limiting component to restrict the movement range of the buoyancy pack. Four lugs are connected to the buoyancy pack through the limiting component.

[0008] Preferably, the limiting component includes a rectangular plate bonded and fixed to the top of the buoyancy bag, the bottom ends of the four hanging ears all penetrate the inner wall of the liquid storage tank and are fixed to the top of the rectangular plate, two limiting blocks are fixed on both sides of the rectangular plate, and two limiting grooves are opened on the inner wall of the liquid storage tank for the two limiting blocks to slide up and down.

[0009] Preferably, the outer wall of the liquid storage tank is fixed with a flow guide plate, and the top surface of the flow guide plate is inclined.

[0010] Preferably, a monitoring device is provided on the side of the liquid storage tank. The monitoring device includes a high liquid level sensor and a low liquid level sensor arranged sequentially from top to bottom on the side of the liquid storage tank. The detection ends of both the high liquid level sensor and the low liquid level sensor penetrate the inner wall of the liquid storage tank and are in contact with the fire extinguishing liquid.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model is a self-activated fire extinguishing system that automatically releases extinguishing liquid to cover the fire source by triggering the melting of the heat-sealing block through temperature sensing. It requires no manual intervention. The system will release the extinguishing liquid through heat sensing. This automatic fire extinguishing method can react quickly in the early stage of a fire, reduce the spread and spread time of the fire, and thus reduce the losses caused by the fire.

[0013] 2. This utility model improves the fire extinguishing effect through the linkage mechanism of fire extinguishing liquid and fire extinguishing powder. The fire extinguishing liquid first extinguishes the fire source. When the liquid level drops, the buoyancy pack triggers the rectangular plate to move down, puncture the filling ring and release the fire extinguishing powder, which quickly spreads and covers the fire source, enhancing the fire extinguishing effect and ensuring the combination of multiple fire extinguishing methods and the continuity of the fire extinguishing process.

[0020] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0021] Most AC charging stations on the market are currently installed in open-air environments, exposed to direct sunlight for extended periods, especially during the hot summer months. High temperatures accelerate the aging of internal cables, increasing the risk of fire. Furthermore, if a short circuit or external fire occurs in an AC charging station, existing designs often lack effective fire prevention measures, allowing the fire to spread easily and cause larger-scale fires, resulting in significant economic losses and safety risks. To address the issues of charging stations being exposed to high temperatures for extended periods, leading to internal cable aging and fire hazards, and the lack of effective fire prevention measures in existing designs, which facilitate the spread of fire and increase safety risks and economic losses, please refer to [link to relevant documentation]. Figures 1-4 This embodiment provides an AC charging pile with fire extinguishing function, including a charging pile 1. A fire extinguishing component 2 is provided on the top of the charging pile 1. The fire extinguishing component 2 includes a liquid storage tank 21 fixed on the top of the charging pile 1. The liquid storage tank 21 is filled with fire extinguishing liquid. Several liquid flow holes 22 penetrating through the inside and outside are opened on the inner walls of the four sides of the liquid storage tank 21. A heat-melting sealing block 23 is fixed inside each of the liquid flow holes 22. A flow guide plate 24 is fixed on the outer wall of the liquid storage tank 21, and the top surface of the flow guide plate 24 is inclined. When a fire occurs in charging pile 1, the temperature will rise rapidly. The heat-melting seal 23 on top of the liquid storage tank 21 will automatically melt when the temperature reaches a certain threshold. After the heat-melting seal 23 melts, it will open the flow hole 22, allowing the extinguishing liquid inside the liquid storage tank 21 to be released. This design is a self-activated fire extinguishing system. When a fire occurs, no manual intervention is required. The system will trigger the release of the extinguishing liquid through heat sensing. This automatic fire extinguishing method can react quickly in the early stages of a fire, reducing the spread and spread time of the fire, thereby reducing the losses caused by the fire. Once the extinguishing liquid is released, it will flow along the inclined surface of the guide plate 24 and cover the outer wall of charging pile 1. In this way, the extinguishing liquid can quickly come into contact with the fire source and play a role in cooling and isolating oxygen. The coverage of the extinguishing liquid can not only extinguish the fire source itself, but also prevent the fire from spreading outward. After the extinguishing liquid is released to the fire source, it will quickly cool down and isolate oxygen or interrupt the combustion process through chemical reaction, thereby playing a role in extinguishing the fire.

[0022] like Figures 2-4As shown, the auxiliary extinguishing component 3 includes four lugs 31 mounted on the top of the liquid storage tank 21. Each lug 31 is vertically welded from a vertical plate and a horizontal plate. A piercing needle 32 is fixed to the bottom of the horizontal plate. A filling ring 33 is fixed to the outer wall of the liquid storage tank 21. Extinguishing powder is filled inside the filling ring 33. A power component is installed inside the liquid storage tank 21 to drive the piercing needle 32 to move down and pierce the filling ring 33. The power component includes a buoyancy pack 35 floating on the top of the extinguishing liquid. A limiting component is installed on the top of the buoyancy pack 35 to limit the movement range of the buoyancy pack 35. The four lugs 31 are connected to the buoyancy pack 35 through the limiting component. The limiting component includes a rectangular plate 34 bonded to the top of the buoyancy pack 35. The bottom ends of the four lugs 31 penetrate the inner wall of the liquid storage tank 21 and are fixed to the top of the rectangular plate 34. Two limiting blocks are fixed on both sides of the rectangular plate 34. Two limiting grooves are opened on the inner wall of the liquid storage tank 21 for the two limiting blocks to slide up and down. By gradually reducing the extinguishing liquid level, the buoyancy pack 35 drives the rectangular plate 34 downward, triggering the piercing needle 32 to pierce the filling ring 33 and release extinguishing powder. This achieves multi-level linkage of the fire extinguishing system. The extinguishing liquid first provides initial cooling and oxygen isolation to the fire source. When the extinguishing liquid is insufficient, the extinguishing powder in the filling ring 33 explodes, which can spread and cover the fire source in a short time, enhancing the fire extinguishing effect. By combining the extinguishing liquid and the extinguishing powder, different fire extinguishing effects can be produced for different types of fire sources. After the extinguishing powder explodes, it can quickly cover the area around the fire source, which helps to continue to control the fire after the extinguishing liquid is exhausted. This enhances the sustainability and coverage of the fire extinguishing system and effectively improves the fire extinguishing effect.

[0023] like Figure 2 As shown, a monitoring device 4 is installed on the side of the storage tank 21. The monitoring device 4 includes a high-level sensor 41 and a low-level sensor 42 arranged sequentially from top to bottom on the side of the storage tank 21. The detection ends of both the high-level sensor 41 and the low-level sensor 42 penetrate the inner wall of the storage tank 21 and are in contact with the extinguishing liquid. When the extinguishing liquid level in the storage tank 21 begins to drop, the high-level sensor 41 detects the level change and transmits a signal to the external controller, alerting the staff to activate the automatic fire extinguishing system. The time difference between the high-level sensor 41 and the low-level sensor 42 represents the working time of the automatic fire extinguishing system. This time is used to ensure that the extinguishing liquid can be effectively released and to trigger subsequent fire extinguishing measures when the extinguishing liquid is insufficient.

[0024] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
