Description

Technical Field

[0001] This invention relates to the field of vehicle protection technology, specifically a vehicle fire extinguishing device. Background Technology

[0002] In recent years, there have been frequent unfortunate incidents of vehicles catching fire, especially electric vehicles, which have caught fire and spontaneously combusted while parked on the roadside or in parking lots without being started, causing many tragedies.

[0003] The primary cause of electric vehicle fires is thermal runaway of lithium batteries. Causes include external impacts or damage to the battery, overcharging or improper use of charging equipment, and internal short circuits in the battery. These factors can cause the battery temperature to rise sharply and ignite a fire, which must be extinguished as quickly as possible to prevent the fire from spreading.

[0004] However, because electric vehicles use lithium-ion batteries, which can store a large amount of energy, a burning lithium battery undergoes a chemical reaction that causes thermal runaway, leading to continuous self-heating and reignition. Firefighters or automatic sprinkler systems need to use large amounts of water to continuously cool the fire until the reaction is completely over before it can be extinguished. Although using large amounts of water is a more effective way to extinguish lithium battery fires, it may also affect neighboring parked vehicles and buildings. Furthermore, if firefighting relies on the fire department, the first effective time to extinguish the fire may be lost. Utility Model Content

[0005] The purpose of this invention is to provide a vehicle fire extinguishing device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a vehicle fire extinguishing device, comprising a main body and a detection unit. The main body is hollow inside, and a fire blanket is disposed inside the main body. The fire blanket is folded, and pull ropes are fixedly connected to the four corners of the fire blanket. All four pull ropes can unfold the fire blanket. Activation mechanisms are fixedly connected to the inner walls of the main body around the fire blanket. The four activation mechanisms are cylindrical, and a start switch is fixedly connected to the inner wall of each of the four activation mechanisms. The trigger end of the start switch is connected to the signal output end of the detection unit. Gas cylinders are fixedly connected to the inner walls of each of the four activation mechanisms, and a braking component is fixedly connected to the top of each of the four activation mechanisms.

[0007] As a further aspect of the present invention: a first hammer is provided at one end of each of the four excitation mechanisms, and a second hammer is provided at the end of each of the four excitation mechanisms away from the first hammer (a).

[0008] As a further embodiment of the present invention: the ends of the four pull ropes away from the fire blanket are all fixedly connected to the side wall of the first hammer, and the ends of the four pull ropes away from the first hammer are all fixedly connected to the side wall of the second hammer (a).

[0009] As a further embodiment of the present invention: one end of the main body is provided with an opening, and a front cover is provided at the end of the main body near the opening.

[0010] As a further embodiment of the present invention: the bottom of the front cover is rotatably connected to the bottom of the main body near the opening via a hinge, and the top of the front cover is magnetically connected to the top of the main body via a magnetic block.

[0011] As a further embodiment of the present invention: the detection unit is equipped with a battery, a temperature sensor and a smoke sensor, and the detection unit is located on the top of the vehicle.

[0012] Compared with existing technologies, the advantages of this invention are as follows: In this invention, the detection unit monitors vehicle temperature and smoke levels in real time, and triggers the fire extinguishing mechanism immediately upon detecting any abnormality, significantly shortening the response time. The fire blanket quickly covers the fire source, isolating it from air, blocking heat radiation and toxic fumes, effectively controlling the spread of the fire and achieving instantaneous extinguishing. The entire fire extinguishing process is completed automatically without human intervention, reducing the risk of personal injury. The device has a compact design and can be easily installed on the roof of a vehicle or other suitable location without occupying extra space. Using a fire blanket instead of chemical extinguishing agents reduces environmental pollution and secondary damage to the vehicle. Attached Figure Description

[0019] Please see Figures 1-7 In this embodiment of the invention, a vehicle fire extinguishing device includes a main body 1 and a detection element attached to the main body 1.

[0020] The main body 1 is provided with at least two firing structures 3 and a fire blanket 4. Each firing structure 3 is provided with a first hammer 31 and a braking element 33 is provided on its start switch 32. The fire blanket 4 is connected to the first hammer 31 and the second hammer 31a at both ends by a pull rope 41. After being folded back and forth appropriately, it is placed in the main body 1. The detection element is connected to the braking element 33.

[0021] The main body 1 and the detection element are installed at an appropriate position above the parked vehicle. When the vehicle catches fire due to a malfunction, the detection element can detect it and drive the brake 33 to cause the firing mechanism 3 to fire the first hammer 31 outward. The flying first hammer 31 pulls the fire blanket 4 out of the main body 1 and onto the vehicle. In the early stage of the fire, the fire blanket covers the burning vehicle to isolate it from the air, block heat radiation and toxic smoke, thereby achieving the effect of instant fire extinguishing.

[0022] In one of the aforementioned vehicle fire extinguishing devices, the lower end of the front cover 12 of the main body 1 is connected to the lower end of the opening 11 by a hinge to form a hingeable shape. The upper end of the front cover 12 and the upper end of the opening 11 are respectively provided with corresponding magnets. By means of the magnets attracting magnets, the front cover 12 is closed to the front edge of the main body 1.

[0023] In one of the aforementioned vehicle fire extinguishing devices, the firing structure 3 can be generated by using the kinetic energy of gas, high-pressure air, and CO2 to create the firing hammer.

[0024] In one of the aforementioned vehicle fire extinguishing devices, the braking component 33 can be a solenoid valve. By pressing the start switch 32 through the action of the solenoid valve, the hammer is activated.

[0025] Please also refer to Figure 1 and Figure 2 This is a three-dimensional drawing and a structural diagram of the main body 1 of this creation.

[0026] As shown in the figure, the device includes a main body 1 and a detection element 2 attached to the main body 1.

[0027] The main body 1 is generally box-shaped, with an opening 11 at its front end, and a front cover 12 that can be opened and closed at the opening 11.

[0028] In this embodiment, the lower end of the front cover 12 is provided with a hinge to connect to the lower end of the opening 11 of the main body 1, so as to form a hingeable shape. The upper end of the front cover 12 and the upper end of the opening 11 of the main body 1 can be provided with corresponding magnets, so that the front cover 12 can be closed to the front edge of the main body 1 by means of the magnets attracting magnets.

[0029] The main body 1 is provided with at least two firing structures 3 and a fire blanket 4. Each firing structure 3 is provided with a first hammer 31, and a braking element 33 is provided with the start switch 32 of the firing structure 3.

[0030] In this embodiment, the firing structure 3 can generate the kinetic energy to fire the first hammer 31 by using the high pressure of gas, high-pressure air and CO2 from the gas cylinder 34. The braking component 33 can be a solenoid valve. By pressing the start switch 32 through the action of the solenoid valve, the gas cylinder 34 is opened to fire the first hammer 31.

[0031] The fire blanket 4 is connected to the first hammer 31 and the second hammer 31a by a pull rope 41, and is placed inside the main body 1 after being folded back and forth appropriately.

[0032] The detection element 2 is connected to the braking element 33 to detect fire signals, smoke signals generated in the early stage of a fire, and abnormal temperature signals in the surrounding environment. When such signals are detected, the braking element 33 is driven to perform a pressing action.

[0033] By combining the aforementioned components, a vehicle fire extinguishing device is constructed.

[0034] The main body 1 and the detection element 2 are installed at an appropriate position above the parked vehicle 5. When the vehicle 5 catches fire due to a malfunction, the detection element 2 can detect it and drive the brake 33 to press the start switch 32, causing the firing mechanism 3 to fire the first hammer 31 outward. The flying first hammer 31 pulls the fire blanket 4 out of the main body 1, and the first hammer 31 and the second hammer 31a pull it down, so that it falls on the vehicle 5. In the early stage of the fire, the fire blanket covers the burning vehicle 5 to isolate the air, block heat radiation and toxic smoke, thereby achieving the effect of instant fire extinguishing.

[0035] In actual use, to improve the fire extinguishing effect, the shape of the fire blanket 4 can be set to be similar to the shape of the vehicle being used, so as to ensure that it can cover the burning vehicle when it is deployed.

[0036] The working principle of this invention is as follows: the main body 1 and the detection unit 2 of a vehicle fire extinguishing device are respectively installed at appropriate positions on the top of the vehicle to ensure that the detection unit 2 can accurately monitor the temperature and smoke conditions around the vehicle.

[0037] Adjust the sensitivity parameters of detection unit 2 according to vehicle type and actual needs to ensure that the fire extinguishing mechanism can be triggered in time in the early stage of a fire.

[0038] Regularly check the operating status of the equipment, including battery power and gas cylinder pressure, to ensure that the equipment is in good standby condition.

[0039] When a vehicle catches fire, the detection unit 2 immediately detects the abnormal signal and triggers the fire extinguishing mechanism. The fire blanket 4 quickly unfolds and covers the burning vehicle to extinguish the fire rapidly.

[0040] After the fire was extinguished, the consumed gas cylinders and damaged parts were promptly replaced to restore the equipment to normal operating condition. Simultaneously, the cause of the fire was investigated and analyzed, and appropriate measures were taken to prevent similar incidents from recurring.
