Description

Technical Field

[0001] The utility model relates to the technical field of fire extinguishing equipment, in particular to an easy-to-use fire extinguishing and cooling device for an automobile chassis and its using method. Background Technique

[0002] At present, some fire extinguishing and cooling devices for automobile chassis appear on the market. For example, the patent name disclosed in the Chinese patent database: Easy-to-use fire extinguishing and cooling device for automobile chassis, patent number: ZL202221785509.8, authorization announcement date: December 9, 2022. Its disclosed technical solution includes a hose connecting pipe, the right end of the hose connecting pipe is fixedly provided with a water inlet pipe, the right end of the water inlet pipe is fixedly provided with a main pipe, the right end of the main pipe is fixedly provided with a fire extinguishing coil pipe, the upper side wall of the fire extinguishing coil pipe is fixedly provided with uniformly arranged direct current nozzles, and uniformly arranged atomizing nozzles are fixedly arranged around the direct current nozzles; mounting plates are fixedly arranged at the four corners inside the fire extinguishing coil pipe, and universal wheels are rotatably arranged at the lower ends of the mounting plates.

[0003] After investigation by the applicant, it is found that the above technical solution has certain deficiencies. When the above technical solution is used, users (such as firefighters) need to manually push the whole device to the lower end of the chassis of the burning vehicle, and spray water through the direct current nozzles and atomizing nozzles to extinguish the fire on the lower side wall of the chassis. The method of manual pushing by users (such as firefighters) for fire extinguishing operations is time-consuming and laborious; the relatively heavy weight of the whole device also makes it inconvenient to use. At the same time, it is difficult to grasp the position of the fire extinguishing coil pipe pushed to the water spraying position of the automobile chassis. Sometimes it may not be pushed in place (such as problems where firefighters do not push far enough due to insufficient force or push too far due to excessive force). In order to better extinguish the fire on the automobile chassis, firefighters sometimes need to push and adjust the fire extinguishing coil pipe multiple times to accurately adjust the water spraying position. In this way, it is easy to cause firefighters to be too close to the fire source, which is easy to cause burns, and there are relatively large safety hazards, especially in the case of a large fire in the automobile. Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and an easy-to-use fire extinguishing and cooling device for an automobile chassis and its using method are proposed.
