AI Technical Summary
In the construction of existing fire training scenarios, it is difficult to truly simulate the disaster scenarios in which shelves collapse due to fire and high temperatures, resulting in fixed training scenarios, simple solutions, and single paths, which cannot effectively improve firefighters' stress resistance and fire handling capabilities in complex environments.
A shelf collapse device for fire fighting training is designed, including base, cabinet body, vertical rod, medium optical axis, electric push rod, limit chain and other components. The vertical rod and cabinet body are driven to rotate through the electric push rod, simulate the shelf collapse scenario, and safe collision prevention and automatic reset is achieved through limit chain and pads.
It realizes a more realistic simulation of the shelf collapse scenario at the fire accident site, enhances the variability and safety of the training scenario, and improves the training effect and fire handling capabilities of firefighters in complex environments.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of fire training, in particular to a shelf collapse device used for fire training. Background Art
[0002] In the construction of real fire simulation training scenes for firefighters, it is necessary to restore the complex environment of the fire accident scene as realistically as possible. In particular, when constructing simulated fire scenes in shops and warehouses with cargo storage needs, it is necessary to consider the accident phenomenon of cargo storage shelves collapsing due to complex factors that affect the stability of the shelf structure, such as direct contact with flames and continuous high temperatures.
[0003] In general scene construction, most of the time, fixed simulated shelf structures are used to achieve simple scene reproduction. Such scene construction has the disadvantages of fixed scenes, simple training plans, and single training paths. As a result, it can only simply restore the composition of material elements at the accident scene, but cannot simulate and construct secondary disaster scenes caused by fire and high temperature of material elements.
[0004] Therefore, there is still a real need to build a simulated training scene of a real fire for firefighters to further enhance their resilience and ability to handle fire accidents in dangerous and complex environments. In order to better meet the needs of scene construction, in training scenes with cargo storage needs such as simulated shops and warehouses, a shelf collapse device can be set up to simulate the shelf collapse disaster scene caused by fire and high temperature, and restore the fire accident scene more realistically. The shelf collapse device can be connected to the automatic control system, with safety anti-collision function, automatic reset function, and can also realize the transformation of training paths.
[0005] The shelf collapse device can provide firefighters with a more realistic, safe and reliable prop for constructing training scenarios during real fire simulation training. Utility Model Content
