Description

Technical Field

[0001] The invention relates to the technical field of safety technology, and in particular to a movable device for preventing the fire of an electric car in a garage from spreading. Background Art

[0002] With the popularity of electric vehicles, electric vehicles have gradually become the mainstream means of transportation due to their environmental protection and high efficiency. However, the large-capacity lithium-ion batteries of electric vehicles may experience thermal runaway under certain conditions, leading to safety hazards such as fire. Especially in a closed or semi-closed garage environment, once an electric vehicle catches fire, the fire may quickly spread to surrounding vehicles and buildings, causing serious property losses and threats to personal safety. Although traditional fire protection measures such as sprinkler systems and fire extinguishers can control the fire to a certain extent, they are limited in effect when facing the high-temperature combustion of electric vehicles, and it is difficult to effectively prevent the fire from spreading to the surrounding areas.

[0003] At present, there is a lack of a mobile fire protection device for electric vehicles on the market, which can quickly isolate the fire source in the early stage of the fire, prevent the fire from spreading, and buy precious time for fire extinguishing. Therefore, the development of a mobile, easy-to-operate device that can effectively control the spread of garage fires has become an urgent need in the current electric vehicle fire protection field. Summary of the invention

[0004] According to the technical problems mentioned in the above-mentioned background technology, a movable device for preventing the fire of electric vehicles in the garage from spreading is provided. The device of the present invention can respond quickly in the early stage of an electric vehicle fire, and effectively prevent the flame from spreading to other vehicles and building structures in the garage by isolating the fire source and the fire spread area. The device is designed to be easy to move and deploy, and can quickly form a closed or semi-closed isolation space around the burning vehicle, reduce the impact of high temperature and toxic smoke on the surrounding environment, and improve the efficiency of fire extinguishing. The device not only has excellent high temperature resistance and flame retardancy, but can also cooperate with the automatic fire extinguishing system to further control the fire. Through the implementation of the present invention, the safety protection level of electric vehicle fires can be significantly improved, casualties and property losses can be reduced, and at the same time, a flexible and efficient means of garage fire prevention and control can be provided.

[0005] The technical means adopted by the present invention are as follows:

[0015] Furthermore, the fixed trapezoidal connecting frame is movably connected to the four keels of the first supporting frame except the first keel by bolts, and the bolts are linearly distributed along the trapezoidal hypotenuse. The movable trapezoidal connecting frame is installed at the front end of the first keel, and the root keels of the second supporting frame are also connected to the movable trapezoidal connecting frame by bolts, with the same distribution as the first supporting frame.

[0016] Furthermore, the wheels are fixedly mounted at the front end and the rear end of the first keel; and the handrail is fixedly mounted at the rear end of the first keel.

[0017] Further, the front hydraulic cylinder, the middle hydraulic cylinder and the rear hydraulic cylinder each include: a hydraulic rod and a hydraulic cylinder sleeve;

[0025] Compared with the prior art, the present invention has the following advantages:

[0026] The device of the present invention monitors the temperature around the electric vehicle in real time through a temperature sensor, responds immediately at the beginning of a fire, quickly starts the protection system, isolates and controls the fire source, and greatly reduces the risk of fire spreading. This automated response buys valuable time for fire extinguishing and avoids the delay of traditional manual operation. The device adopts a telescopic structure of a keel, fireproof cotton and a hydraulic rod, which can quickly build an enclosed isolation space to block the spread of the fire. The structure can effectively prevent high temperature and toxic smoke from spreading to other areas in the garage, reducing damage to surrounding vehicles and buildings. The device not only isolates the fire source, but also links with the garage fire sprinkler system to spray water to cool the fireproof cotton, further improving the fire extinguishing effect. The combination of multiple protection measures significantly improves the ability to respond to electric vehicle fires. The controller makes a judgment based on the temperature signal transmitted by the sensor, and accurately controls the actions of key components such as electromagnets and hydraulic rods to ensure that the device operates reliably when a fire occurs. At the same time, the fire alarm linkage system sends an alarm to various areas in the building to ensure the rapid evacuation of personnel and improve overall safety.
