[0022] Example 1
[0023] like Figures 1-4As shown, the system includes a base plate 1. A cooler 4 is fixed to the top of one end of the base plate 1. A controller 10 is fixed to the top of the cooler 4. Guardrails 5 are fixed to both sides of the top of the base plate 1 near the cooler 4. To facilitate vehicle inspection, a rolling hub 2 is installed at the top of the base plate 1, at the end of the guardrail 5 away from the cooler 4. To facilitate securing the rear wheels of the vehicle and prevent the vehicle from moving, a rear wheel fixing bracket 3 is installed at the top of the other end of the base plate 1. To facilitate monitoring whether the vehicle is on fire, a monitoring component is installed at the top of the base plate 1, between the cooler 4 and the rolling hub 2. To facilitate timely fire extinguishing when the vehicle catches fire, a fire extinguishing component is installed at the top of the base plate 1, corresponding to the monitoring component. To issue an alarm immediately when the vehicle catches fire, an alarm 23 is fixed at the top of the cooler 4, near the controller 10.
[0024] During operation, the vehicle is first driven to the top of the base plate 1, with the front wheels positioned at the top of the rolling hub 2. The rear wheels are then secured using the rear wheel mounting bracket 3. The vehicle is then inspected. Through the coordinated design of the controller 10, alarm 23, monitoring components, and fire extinguishing components, the system can detect flames around the vehicle. When a flame is detected, the alarm 23 sounds, and the operator can manually disable the fire suppression system within 30 seconds. If no human intervention occurs after 30 seconds, the controller 10 automatically triggers the fire extinguishing components to extinguish the fire on the vehicle, effectively reducing the risk of injury to the site or personnel from vehicle flames.
[0025] Example 2
[0026] like Figures 1-4 As shown, in order to facilitate the monitoring of flames on the sides and tops of different vehicles, the monitoring component includes a movable frame 6. The movable frame 6 is set at the top of the two guardrails 5 and is slidably connected to the guardrails 5. The inner sides of both ends and the lower top of the movable frame 6 are fixed with a first external flame detector 11. In order to facilitate the immediate alarm when a flame is detected, the first external flame detector 11 is electrically connected to the alarm 23. To facilitate the movement of the movable frame 6, the lower end of the movable frame 6 is fixed with a moving wheel 20.
[0027] To facilitate flame detection at the front and bottom of the vehicle, the monitoring component also includes two second external flame detectors 12. The two second external flame detectors 12 are respectively fixed at one end of the air cooler 4 near the guardrail 5 and the top of the base plate 1, and are located between the rolling hub 2 and the air cooler 4. The second external flame detectors 12 are electrically connected to the alarm 23.
[0028] Before inspecting the vehicle, the mobile frame 6 is moved and slid along the guardrail 5 to adjust it to the position where the side of the vehicle needs to be monitored. When the vehicle is on fire, multiple first-line flame detectors 11 detect the flame on the top and side of the vehicle. When a flame is detected, the alarm 23 is triggered and an alarm is sounded. If no one turns it off within 30 seconds, the fire extinguishing assembly is activated by the controller 10 to extinguish the fire.
[0029] Example 3
[0030] like Figures 1-4 As shown, the fire extinguishing assembly includes a carbon dioxide storage tank 8, which is located on the outer side of one end of a movable frame 6. To facilitate the movement of the movable frame 6 and the simultaneous movement of the carbon dioxide storage tank 8, a fixing plate 7 is fixed to the lower end of the side of the movable frame 6 corresponding to the carbon dioxide storage tank 8. The carbon dioxide storage tank 8 is located at the top of the fixing plate 7. A fixing ring 9 is fitted on the outer side of the carbon dioxide storage tank 8. The fixing ring 9 is fixedly connected to the movable frame 6, and the carbon dioxide storage tank 8 is slidably connected to the fixing ring 9. To facilitate the control of carbon dioxide emission from the carbon dioxide storage tank 8, a first electrically controlled valve 21 is fixed to the top of the carbon dioxide storage tank 8. The first electrically controlled valve 21 is electrically connected to the controller 10. To facilitate the delivery of the carbon dioxide discharged from the carbon dioxide storage tank 8, a second delivery pipe 17 is fixed to the outlet of the first electrically controlled valve 21. To facilitate the discharge of carbon dioxide to the fire location, a second spray pipe 18 is fixed at the position corresponding to the first external flame detector 11 on the second delivery pipe 17. A second spray head 19 is fixed to the end of the second spray pipe 18 away from the second delivery pipe 17.
[0031] The fire extinguishing assembly also includes a second carbon dioxide storage tank 13, which is fixed to the top of the base plate 1 and close to the air cooler 4. A second electrically controlled valve 22 is fixed to the top of the second carbon dioxide storage tank 13. The second electrically controlled valve 22 is electrically connected to the controller 10. A first delivery pipe 14 is fixed to the outlet of the second electrically controlled valve 22. In order to facilitate fire extinguishing of the bottom and front of the vehicle, a first spray pipe 15 is fixed at the position corresponding to the first external flame detector 11 on the first delivery pipe 14. A first spray head 16 is fixed at the end of the first spray pipe 15 away from the first delivery pipe 14.
[0032] When the vehicle fire lasts for more than 30 seconds, the controller 10 sends a signal to the first electronically controlled valve 21 and the second electronically controlled valve 22, causing the first electronically controlled valve 21 and the second electronically controlled valve 22 to open and deliver carbon dioxide from carbon dioxide storage tank 1 8 and carbon dioxide storage tank 2 13 through carbon dioxide storage tank 2 13, the second delivery pipe 17, the second injection pipe 18 and the first injection pipe 15. Then, the carbon dioxide is sprayed outward through the second injection head 19 and the first injection head 16 to extinguish the fire at the location of the vehicle fire.
