Description

Technical Field

[0001] This utility model relates to the field of fire extinguishing technology for charging piles, and in particular to a fire extinguishing device for electric vehicle charging piles. Background Technology

[0002] Charging stations are devices specifically designed to provide electrical power to electric vehicles. Fire extinguishing devices for charging stations are used to prevent and control fires caused by charging stations.

[0003] Patent CN214929074U discloses an automatic fire-extinguishing charging pile. It includes a charging pile body, a charging box, and a fire extinguisher. Both the charging box and the fire extinguisher are mounted on the charging pile body. The charging box has a charging head, and the fire extinguisher has an activation switch and a nozzle. When using this patent to extinguish a fire at the charging pile, a thermal trigger device melts, causing a first compression spring to push a second spring seat and a cylindrical sliding sleeve to move. The second compression spring then pushes a ring-shaped stop block to release the limiting ball. The limiting ball slides out, releasing the limiting ball, and the control lever moves to activate the switch, opening the fire extinguisher to extinguish the fire. However, because the aforementioned patent has a slow triggering time, requiring a certain temperature to be reached, and because it only has the function of extinguishing fires at the charging pile, in the event of a fire at a car using a charging pile, the fire could spread to the car and affect surrounding property, leading to greater losses.

[0004] Therefore, there is a need to provide a fire extinguishing device for electric vehicle charging piles with dual fire extinguishing functions. Utility Model Content

[0005] To overcome the shortcomings of existing patents, such as slow triggering, the need to reach a certain temperature, and the fact that these patents only have the function of extinguishing fires on charging piles, which can cause fires to spread to the car and surrounding objects when a fire occurs while the charging pile is in use, resulting in greater losses, this utility model provides a fire extinguishing device for electric vehicle charging piles with dual fire extinguishing functions.

[0006] To address the aforementioned problems, this utility model adopts the following technical solution: a fire extinguishing device for an electric vehicle charging pile, comprising a base plate, a top plate, a smoke sensor, a controller, an alarm, and partitions. Two partitions are fixedly connected to the base plate, and a top plate is fixedly connected between the two partitions and the base plate. A smoke sensor is installed inside the top plate, and a controller is also installed inside the top plate, electrically connected to the smoke sensor. An alarm is installed on the top plate, electrically connected to the controller. The device also includes a first liquid storage tank, a first liquid pump, a corrugated pipe, and a spray nozzle. The system includes components, a second liquid storage tank, a second liquid pump, and a spray nozzle. Two first liquid storage tanks are fixedly connected to the top plate. A first liquid pump is installed on the first liquid storage tank. A connecting pipe is connected to the first liquid pump. A corrugated pipe is connected to the connecting pipe. A spraying component is connected to the corrugated pipe. The spraying component is located above the first liquid storage tank. Two second liquid storage tanks are fixedly connected inside the bottom plate. A second liquid pump is installed on the second liquid storage tank. A spray nozzle is connected to the second liquid pump. The spray nozzle is located inside the bottom plate. The first and second liquid pumps are electrically connected to the controller.

[0007] Furthermore, it also includes a frame, electric slide rails, electric sliders, folding doors, and pull plates. The frame is fixed between the bottom plate, top plate, and partition. Two electric slide rails are installed on each frame. The two electric slide rails are electrically connected to the controller. Electric sliders are installed on the electric slide rails and slide on the electric slide rails. A pull plate is installed between the two electric sliders. A folding door is installed between the pull plate and the frame.

[0008] Furthermore, it also includes a sliding plate, a guide rod, a servo motor, a lead screw, and a sliding frame. The sliding plate is fixedly connected to the spraying assembly, the guide rod is fixedly connected between the two partitions, the two sliding blocks slide on the guide rod, the servo motor is installed on the partition, the servo motor is electrically connected to the controller, the output shaft of the servo motor is mounted with a lead screw through a coupling, the sliding frame is fixedly connected to the spraying assembly, and the sliding frame is threadedly connected to the nearby lead screw.

[0009] Furthermore, it also includes light strips, with light strips installed on the partition.

[0010] Furthermore, it also includes an inclined plate, which is fixedly attached to the base plate.

[0011] Furthermore, it also includes a transparent plate, with both the second and first liquid storage tanks having a transparent plate embedded in them.

[0012] Compared with the prior art, the present invention has the following technical effects: 1. By sensing the smoke generated when a fire starts through a smoke sensor, the smoke sensor sends a signal to the controller, which then controls the first liquid pump, the second liquid pump, and the alarm to start. The alarm sounds, the first liquid pump draws water from the first storage tank, and the water is sprayed from the spray assembly through the connecting pipe and the corrugated pipe onto the charging pile and the vehicle for initial fire extinguishing, quickly reducing the temperature of the fire source area and suppressing the spread of the fire. The second liquid pump draws water from the second storage tank, and the water is sprayed from the nozzle onto surrounding objects, thus performing dual fire extinguishing, thereby increasing the fire extinguishing efficiency, ensuring safety over a wider area, and reducing losses.

[0013] 2. The controller activates two electric sliding rails, causing the electric sliders on the two rails to slide downwards. This causes the two electric sliders to move the pull plate downwards, thus unfolding the folding door and covering the opening. This isolates the fire from the outside oxygen, causing the fire to gradually weaken and eventually extinguish due to lack of oxygen.

[0014] 3. The servo motor is started by the controller. The output shaft of the servo motor drives the lead screw to rotate, which causes the sliding frame on the lead screw to move the spraying components. The corrugated pipe extends and shortens, thereby enabling a wider spraying range and more uniform coverage. When dealing with large-area fires, it can significantly improve the fire extinguishing efficiency. Attached Figure Description

Detailed Implementation

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0025] Example 1: A fire extinguishing device for an electric vehicle charging station, see reference. Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 and Figure 8As shown, the system includes a base plate 1, a top plate 2, a smoke sensor 3, a controller 4, an alarm 5, and partitions 6. Multiple openings are evenly spaced at the bottom of the base plate 1. Partitions 6 are welded to both sides of the base plate 1. The top plate 2, L-shaped, is welded to the two partitions 6 and the base plate 1. The base plate 1, top plate 2, and partitions 6 are made of fire-resistant material. A smoke sensor 3 (RS485 type) is bolted to the top of the top of the top plate 2. The controller 4 is bolted to the top of the top of the top plate 2, located in front of the smoke sensor 3 and electrically connected to it. An alarm 5 is bolted to the front of the top of the top of the top plate 2, and the controller 4 is electrically connected to the alarm 5. The system also includes a first liquid storage tank 8, a first liquid pump 9, a bellows 10, and a spray assembly. 11. A second liquid storage tank 13, a second liquid pump 14, and a spray pipe 15 are symmetrically fixed to the left and right sides of the rear inner side of the top plate 2. A first liquid storage tank 8 is installed at the bottom of the first liquid storage tank 8 by bolt connection. A connecting pipe 1001 is connected to the bottom of the first liquid pump 9. A corrugated pipe 10 is connected to the end of the connecting pipe 1001. A spray assembly 11 is connected to the end of the corrugated pipe 10. The spray assembly 11 consists of a water pipe and multiple nozzles. The spray assembly 11 is located above the first liquid storage tank 8. A second liquid storage tank 13 is symmetrically fixed to the left and right sides of the rear inner side of the bottom plate 1. A second liquid pump 14 is installed at the bottom of the second liquid storage tank 13 by bolt connection. A spray pipe 15 is connected to the bottom of the second liquid pump 14. The spray pipe 15 is located inside the bottom plate 1. The spray nozzle of the spray pipe 15 is aligned with the opening on the bottom plate 1. The opening allows the water sprayed by the spray pipe 15 to accurately reach the fire source. The first liquid pump 9 and the second liquid pump 14 are electrically connected to the controller 4.

[0026] See Figure 8 As shown, it also includes a light strip 7, which is installed in the middle of the partition 6.

[0027] See Figure 1 As shown, it also includes an inclined plate 24, which is provided on the front side of the base plate 1 by welding.

[0028] See Figure 5 As shown, it also includes a transparent plate 25. The transparent plate 25 is embedded in the front side of both the second liquid storage tank 13 and the first liquid storage tank 8.

[0029] When this device is needed, the charging pile is first installed on the top plate 2. When the charging pile is needed, the vehicle is driven onto the bottom plate 1. The ramp 24 facilitates vehicle access to the charging area, and the light strip 7 facilitates use of the charging pile at night. Then, the charging pile is used for charging. If the charging pile catches fire during charging, the smoke sensor 3 detects the smoke generated by the fire and sends a signal to the controller 4. This quickly triggers the controller 4 to activate the first liquid pump 9, the second liquid pump 14, and the alarm 5. The alarm 5 sounds an alarm, and the first liquid pump 9 then draws out the first storage liquid. The water in tank 8 is sprayed from the spray assembly 11 through the connecting pipe 1001 and the corrugated pipe 10 onto the charging pile and the vehicle for initial fire suppression, quickly reducing the temperature of the fire source area and inhibiting the spread of the fire. The second pump 14 draws water from the second storage tank 13, which is then sprayed from the nozzle 15 onto surrounding objects, thus performing dual fire suppression, thereby increasing fire suppression efficiency, ensuring safety over a wider area, and reducing losses. During fire suppression, the location of the fire can be determined by the alarm issued by the alarm 5. The transparent plate 25 makes it easy to see the remaining water in the first storage tank 8 and the second storage tank 13.

[0030] Example 2: Based on Example 1, refer to Figures 2-4 As shown, it also includes a frame 16, an electric slide rail 17, an electric slider 18, a folding door 19, and a pull plate 20. The frame 16 is welded between the bottom plate 1, the top plate 2, and the front side of the partition plate 6. The electric slide rail 17 is installed on both the left and right sides of the frame 16 by bolts. The two electric slide rails 17 are electrically connected to the controller 4. The electric slider 18 is installed on the electric slide rail 17 and slides on the electric slide rail 17. The pull plate 20 is installed between the two electric sliders 18. The folding door 19 is set between the pull plate 20 and the frame 16. The folding door 19 is made of fire-resistant material.

[0031] When the smoke sensor 3 detects a fire, the controller 4 activates the two electric slide rails 17, causing the electric sliders 18 on the two electric slide rails 17 to slide downwards. The two electric sliders 18 then move the pull plate 20 downwards, thereby unfolding the folding door 19 and covering the opening. This isolates the fire from the outside oxygen, causing the fire to gradually weaken and eventually extinguish due to lack of oxygen. After the fire is extinguished, the controller 4 controls the electric slide rails 17 to drive the electric sliders 18 to slide upwards, folding the folding door 19 back up.

[0032] See Figure 3 , Figure 6 , Figure 7 and Figure 8As shown, it also includes a sliding plate 1101, a guide rod 12, a servo motor 21, a lead screw 22, and a sliding frame 23. The sliding plate 1101 is fixedly connected to the rear of the water pipe of the spray assembly 11. The guide rod 12 is welded between the upper parts of the two partitions 6. The two sliding blocks slide on the guide rod 12. The servo motor 21 is installed in the upper part of the partition 6 by bolt connection. The servo motor 21 is electrically connected to the controller 4. The output shaft of the servo motor 21 is installed with the lead screw 22 through a coupling. The sliding frame 23 is fixedly connected to the middle of the water pipe of the spray assembly 11. The sliding frame 23 is threadedly connected to the nearby lead screw 22.

[0033] When the spray assembly 11 is extinguishing a fire, the controller 4 starts the servo motor 21. The output shaft of the servo motor 21 drives the lead screw 22 to rotate, which causes the sliding frame 23 on the lead screw 22 to move the spray assembly 11. The bellows 10 extends and shortens, thereby enabling a wider spray range and more uniform coverage. When dealing with large-area fires, it can significantly improve the fire extinguishing efficiency. After the fire is extinguished, the controller 4 will turn off the servo motor 21.
