Description

Technical Field

[0001] This utility model relates to the field of charging pile technology, and in particular to a fire monitoring and anti-spread device for charging piles. Background Technology

[0002] Charging stations are devices that provide electrical power to electric vehicles and are commonly found in public places and residential areas. Electric vehicle fires are usually caused by battery thermal runaway, which can be due to overcharging, short circuits, mechanical damage, or high-temperature environments. During charging, if the charging station malfunctions or the battery management system fails, abnormal current and voltage may occur, leading to battery overheating. Furthermore, if the area around the charging station lacks fireproofing, the fire can spread rapidly.

[0003] Existing charging stations mainly consist of the charging station body, charging modules, cables, and payment systems. The charging area and electrical components are usually not physically separated. If a battery or wiring catches fire, the flames can easily spread to adjacent charging stations or vehicles through gaps in the cables or equipment. Furthermore, the charging station body is often made of ordinary metal or plastic, which is not flame-retardant, increasing the risk of fire spread. This design not only threatens user safety but may also cause a chain reaction of fires, increasing the difficulty of rescue operations. Utility Model Content

[0004] The technical problem this invention aims to solve is that the charging pile structure does not integrate fire prevention and control functions to prevent the spread of fire, and therefore cannot provide timely control and early warning.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a fire monitoring and anti-spread device for charging piles, including a frame, connecting compartments fixedly connected to both sides of the frame, a rotating column fixedly installed inside the connecting compartment, telescopic rods extending outwards fixedly installed on the top and bottom sides of the rotating column, a support column fixedly connected to the other end of the telescopic rod, and a retractable partition wall fixedly installed between the support column and the inner wall of the connecting compartment.

[0006] As a further improvement of this utility model, the partition wall is composed of multiple ring-locked square frame walls, and a connecting frame is fixedly connected at the beginning and end of the connection. The square frame walls are connected to each other by the connecting frame snap-fit.

[0007] As a further improvement of this utility model, the support column is configured as a prism with a hollow groove at the bottom, and a handle is fixedly provided on one side of the prism. A support rod is slidably connected in the hollow groove, and the support rod is fastened to the support column by bolts.

[0008] As a further improvement of this utility model, a protrusion is fixedly provided on the top of the support column, a snap-fit ​​column is fixedly connected to one side of the protrusion, and a snap-fit ​​square groove for snap-fitting the snap-fit ​​column is fixedly provided on the top of the connecting compartment.

[0009] As a further improvement of this utility model, a pressure sensor is fixedly installed inside the snap-fit ​​square groove, and the pressure sensor is electrically connected to a controller.

[0010] As a further improvement of this utility model, two rectangular light strips are fixedly installed on one side of the frame, and buzzer alarms are installed on both sides of the rectangular light strips. The controller is electrically connected to the rectangular light strips and the buzzer alarms.

[0011] The beneficial effects of this utility model are as follows: 1. By setting deployable isolation devices on both sides of the charging pile frame, this utility model achieves physical isolation between charging piles or between charging piles and vehicles in the event of a fire, effectively preventing the spread of flames and reducing the risk of fire spread. The partition wall adopts a multi-segment interlocking square frame wall combination, which has good extensibility and flame-retardant performance, and can be flexibly deployed or retracted according to the site conditions. The support column structure is reasonably designed, and together with the support rods and bolts, it can form a stable support, effectively sealing the spread gaps.

[0012] 2. Simultaneously, the system integrates multiple sensors and controllers, enabling rapid identification and activation of audible and visual alarms when the device is abnormally moved or a fire alarm is triggered, further enhancing the equipment's safety and security capabilities. This design not only improves fire prevention in charging scenarios but also buys valuable time for rescue in emergencies, significantly improving operational safety and management efficiency.

It should also be understood that the term “and / or” as used herein refers to and includes one or more of the associated listed items, any or all possible combinations thereof.

[0020] To make the technical problems to be solved, the technical solutions, and the beneficial effects of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0021] This utility model provides a fire monitoring and anti-spread device for charging piles, including a frame 1;

[0022] As attached Figure 1-4 As shown, connecting compartments are fixedly connected to both sides of the frame 1. Rotating columns 2 are fixedly installed inside the connecting compartments, providing limited angular steering (within 25°). Extending telescopic rods 3 are fixedly installed on the top and bottom sides of the rotating columns 2. The telescopic rods 3 are configured as multiple concave sleeves, with their ends fixedly connected. A support column 4 is fixedly connected to the other end of the telescopic rod 3. A retractable partition wall 5 is fixedly installed between the support column 4 and the inner wall of the connecting compartment. The partition wall 5 consists of multiple interlocking square frame walls, with connecting square frames 6 fixedly connected at their ends. The square frame walls are interconnected via the connecting square frames 6. The multi-segment partition wall 5 is combined and connected to each other, providing extensibility. The partition wall 5 is made of ABS flame-retardant board, and the base material is standard ABS resin (such as LG HI121H or CHIMEIPA-757). Brominated flame retardants are used, along with the synergist antimony trioxide (Sb2O3), ensuring moderate cost and good processing performance.

[0023] As attached Figure 1-4 As shown, the support column 4 is a prism with a slot at the bottom, and a handle is fixedly installed on one side of the prism. A support rod 7 is slidably connected in the slot, and the support rod 7 is fastened to the support column 4 by bolts. The support rod 7 and bolts can block the combustion path. A protrusion 8 is fixedly installed on the top of the support column 4, and a snap-fit ​​column is fixedly connected to one side of the protrusion 8. A snap-fit ​​square groove 9 for snap-fitting the snap-fit ​​column is fixedly installed on the top of the connecting compartment. The protrusion 8 and the snap-fit ​​square groove 9 can fix the support column 4 to one side of the connecting compartment, saving space in non-fire situations.

[0024] As attached Figure 1 , 3 As shown, a pressure sensor is fixedly installed inside the snap-fit ​​slot 9, and the pressure sensor is electrically connected to a controller. The controller uses an STM32f103 microcontroller, and the pressure sensor is an F5Y pressure sensor, which is fixed to the inner wall of the snap-fit ​​slot 9. Normally, the protrusion 8 abuts against the pressure sensor. When someone moves it without authorization, a voltage change occurs at the receiving end of the pressure sensor, which is processed by the controller and triggers an alarm. Two rectangular light strips 10 are fixedly installed on one side of the frame 1, and buzzers are installed on both sides of the rectangular light strips 10. The controller is electrically connected to the rectangular light strips 10 and the buzzers. In case of circuit abnormality or fire, the controller drives the rectangular light strips 10 and the buzzers to work, reminding personnel to quickly reach the corresponding work location.

[0025] Working Principle: In practical implementation, under normal conditions, the frame 1 serves as the main structural support for the entire device, with an internal connecting compartment allowing for the orderly arrangement of various fireproof components. A rotating column 2 is fixedly installed within the connecting compartment, and a telescopic rod 3 is fixedly installed on one side of the rotating column 2. When the system is in normal operation, the telescopic rod 3 keeps the device in a retracted state, ensuring a compact overall structure and minimizing space occupation. A support column 4 is fixedly connected to the other end of the telescopic rod 3, and a partition wall 5 is installed on one side of the support column 4. The partition wall 5 is composed of multiple interlocking square frame walls arranged sequentially, forming a connected whole through connecting square frames 6 fixed at both ends, ensuring the extensibility and tightness of the fireproof partition. To enhance the stability of the support column 4, a support rod 7 is slidably connected within its slot and fixed to the support column 4 with bolts, ensuring that the support column 4 can quickly adjust its support after a fire, guaranteeing the stability of the flame-retardant operation. At the top of the support column 4, a protrusion 8 is provided. One side of the protrusion 8 is fixedly connected to the snap-fit ​​column and is used to cooperate with the snap-fit ​​square groove 9 at the top of the frame 1. When the system is in a safe state, the protrusion 8 snaps into the snap-fit ​​square groove 9, which can effectively fix the support column 4 to one side of the connecting compartment and keep the device in the retracted state.

[0026] When a fire or circuit malfunction occurs, the STM32 controller triggers an alarm signal. Subsequently, the rectangular light strip 10 and the adjacent buzzer alarm are activated in tandem, providing a clear audible and visual warning to the operator, prompting them to immediately initiate fire prevention measures. Immediately after the alarm, the operator can adjust the position of the support rod 7 and fix the support height of the support column 4 with bolts, causing the telescopic rod 3 to drive the support column 4 to quickly extend outward. At the same time, the partition wall 5 expands from a retracted state to a complete flame-retardant partition, forming a continuous and robust physical barrier that effectively prevents the spread of fire to adjacent areas.

[0027] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
