Abstract
Description
Technical Field
[0001] This utility model relates to the field of charging stations, specifically a fire-fighting device for new energy charging stations. Background Technology
[0002] With the popularization of electric vehicles, the development and construction of charging stations are also accelerating. To meet market demand, new energy vehicles now use DC fast charging. DC fast charging is characterized by high current and high voltage, but this also brings safety risks to the charging process of new energy vehicles. It makes it easy for the battery to overheat, the battery to malfunction, the vehicle's wiring to malfunction, or the battery's internal resistance to malfunction during charging. These can all easily lead to fires and combustion during vehicle charging.
[0003] To ensure the safety of electric vehicles during charging, the configuration of fire-fighting equipment at charging stations is particularly important. The fire-fighting equipment configuration of charging piles includes fire extinguishers, smoke detectors, automatic sprinkler systems, fire alarm systems, and other necessary fire-fighting facilities. These facilities together constitute the fire safety guarantee system of the charging pile area, ensuring the safety of electric vehicles during charging. Among them, smoke detectors can detect the concentration of smoke in the air. Once it exceeds a set threshold, it will trigger the alarm system to remind people to take timely measures. This equipment can detect fire hazards in time, providing valuable time for personnel evacuation and initial fire fighting.
[0004] In existing technologies, smoke detectors are typically used in areas where fires may occur. However, when a fire actually breaks out, the smoke detector may be damaged by the fire itself after sending out a fire alarm, thus increasing the cost of fire early warning. Utility Model Content
[0005] This utility model provides a fire-fighting device for new energy charging stations to solve the problems in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a fire-fighting device for a new energy charging station, comprising a protective box, a rotating frame, and a flap. A controller and an electric actuator are respectively installed inside the protective box, and the output end of the electric actuator is fixedly connected to the rotating frame. Shaft holes are provided on both sides of the rotating frame, and hollow shafts are provided on both sides of the flap. The flap is movably hinged to the rotating frame through the hollow shafts and shaft holes. An assembly cavity is provided on the rotating frame, and a drive motor is installed inside the assembly cavity. The output shaft end of the drive motor is fixedly connected to the hollow shaft on one side of the flap. A smoke detector is installed on the flap. The electric actuator, drive motor, and smoke detector are electrically connected to the controller.
[0007] Furthermore, the bottom of the protective box is provided with a T-shaped groove, and the bottom of the rotating frame is provided with a T-shaped slider, which is slidably connected to the protective box through the T-shaped slider and the T-shaped groove.
[0008] Furthermore, the rotating frame is U-shaped and is located at the opening of the protective box.
[0009] Furthermore, a bushing is installed on the shaft hole, and the bushing is located between the shaft hole and the hollow shaft.
[0010] Furthermore, the flap has a wire hole in the middle, and the wire hole is interconnected with the hollow shaft.
[0011] Furthermore, the flap is centered in the rotating frame, and the smoke detector is centered on the flap.
[0012] Compared with the prior art, this utility model provides a fire-fighting equipment for new energy charging stations, which has the following beneficial effects:
[0013] The fire-fighting equipment used in this new energy charging station, through the setting of a protective box, rotating frame, and flap, allows the smoke detector to detect a fire and send a feedback signal to the controller. The controller then controls the electric push rod to extend the rotating frame outward a certain distance, while simultaneously controlling the drive motor to rotate the flap 180° in the opposite direction. After that, the electric push rod drives the rotating frame to reset, thus allowing the smoke detector to be stored in the protective box. This prevents damage to the detector due to excessive fire and ensures that the alarm system can operate normally, thereby reducing the cost of fire early warning. Attached Figure Description

[0018] 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.
[0019] Please see Figures 1-3 This utility model discloses a fire-fighting device for a new energy charging station, including a protective box 1, a rotating frame 2, and a flap 3. A controller 4 and an electric actuator 5 are installed inside the protective box 1, and the output end of the electric actuator 5 is fixedly connected to the rotating frame 2. The rotating frame 2 has shaft holes 6 on both sides, and the flap 3 has hollow shafts 7 on both sides. The flap 3 is movably hinged to the rotating frame 2 through the hollow shafts 7 and shaft holes 6. The rotating frame 2 has an assembly cavity 8, and a drive motor 9 is installed inside the assembly cavity 8. The output shaft end of the drive motor 9 is fixedly connected to the hollow shaft 7 on one side of the flap 3. A smoke detector 1 is installed on the flap. 0. With the installation of the protective box 1, rotating frame 2 and flap 3, when the smoke detector 10 detects a fire, it sends a feedback signal to the controller 4. The controller 4 controls the electric push rod 5 to extend the rotating frame 2 outward a certain distance, and at the same time controls the drive motor 9 to rotate the flap 3 in the opposite direction by 180°. Then, the electric push rod 5 drives the rotating frame 2 to reset, so that the smoke detector 10 is stored in the protective box 1. This can prevent the detector from being damaged due to excessive fire, and ensure that the alarm system can operate normally, thereby reducing the cost of fire early warning. The electric push rod 5, drive motor 9 and smoke detector 10 are electrically connected to the controller 4.
[0020] Specifically, the bottom of the protective box 1 is provided with a T-shaped slide groove 11, and the bottom of the rotating frame 2 is provided with a T-shaped slider 12, and the T-shaped slider 12 and the protective box 1 are slidably connected through the T-shaped slider 12 and the T-shaped slide groove 11.
[0021] In this embodiment, the T-shaped slider 12 and the T-shaped groove 11 mainly serve the functions of positioning and guiding, making the rotary frame 2 more stable when it is displaced.
[0022] Specifically, the rotating frame 2 is U-shaped and is located at the opening of the protective box 1.
[0023] In this embodiment, the rotating frame 2 is a supporting structure used for the installation and connection of the flip plate 3.
[0024] Specifically, a bushing 13 is installed on the shaft hole 6, and the bushing 13 is located between the shaft hole 6 and the hollow shaft 7.
[0025] In this embodiment, the bushing 13 can enclose the hollow shaft 7, so that the surface of the hollow shaft 7 is not damaged by the environment and external objects.
[0026] Specifically, the flap 3 has a wire hole 14 in the middle, and the wire hole 14 is connected to the hollow shaft 7.
[0027] In this embodiment, the arrangement of wire hole 14 and hollow shaft 7 facilitates wiring, which can be connected by spiral cable (whose main function is to provide a retractable connection, suitable for various scenarios that require movement, frequent bending and stretching) or conductive slip ring.
[0028] Specifically, the flap 3 is centered in the rotating frame 2, and the smoke detector 10 is centered on the flap 3.
[0029] In this embodiment, the controller 4 controls the electric push rod 5 to drive the rotating frame 2 to extend outward a certain distance, and at the same time controls the drive motor 9 to drive the flip plate 3 to rotate 180° in the opposite direction. Then, the electric push rod 5 drives the rotating frame 2 to reset, so that the smoke detector 10 is stored in the protective box 1.
[0030] In use, with the protective box 1, rotating frame 2 and flap 3 in place, when the smoke detector 10 detects a fire, it sends a feedback signal to the controller 4. The controller 4 then controls the electric push rod 5 to extend the rotating frame 2 outward a certain distance. At the same time, it controls the drive motor 9 to rotate the flap 3 180° in the opposite direction. After that, the electric push rod 5 drives the rotating frame 2 to reset, so that the smoke detector 10 is stored in the protective box 1. This avoids damage to the detector due to excessive fire and ensures that the alarm system can operate normally, thereby reducing the cost of fire early warning.
[0031] In summary, the fire-fighting equipment for this new energy charging station, through the installation of the protective box 1, rotating frame 2, and flap 3, allows the smoke detector 10 to send a feedback signal to the controller 4 when it detects a fire. The controller 4 then controls the electric push rod 5 to extend the rotating frame 2 outward a certain distance, while simultaneously controlling the drive motor 9 to rotate the flap 3 180° in the opposite direction. After the electric push rod 5 rotates the rotating frame 2 back to its original position, the smoke detector 10 is thus housed inside the protective box 1. This prevents damage to the detector due to excessive fire intensity, ensures the normal operation of the alarm system, and reduces the cost of fire early warning.
