[0002] Safety helmets are core protective equipment used to protect personnel's lives, playing a crucial role in preventing head injuries from impacts with external objects during construction projects. Significant challenges exist in safety helmet management at construction sites: haphazard stacking, confusion during use, and difficulty in maintaining hygiene. To address these issues, a safety helmet storage rack has been developed for storing and categorizing safety helmets.

[0003] Chinese patent CN222708003U proposes a safety helmet placement device, including a base plate, a back plate, and a helmet holder, which makes the safety helmet easy to identify and put away, and facilitates ventilation between the opening of the safety helmet and the back plate.

[0004] Chinese patent CN222532925U proposes a safety helmet storage cabinet for engineering construction, with through holes in the mounting frame to facilitate ventilation of the helmet shell and the diffusion of heat and moisture.

[0005] While the existing technologies mentioned above have solved the problems of classified storage and ventilation of safety helmets, they still have significant shortcomings in terms of functionality (such as washing, drying, and disinfection) and space utilization. Therefore, to meet the needs for a higher degree of integration and intelligence in safety helmet storage management, a safety helmet storage cabinet for construction projects is proposed. Summary of the Invention

[0006] The purpose of this invention is to overcome the shortcomings of existing systems and provide a safety helmet storage cabinet for construction projects, which allows for the cleaning, drying and disinfection of safety helmets.

The inner wall of the cabinet body 1 is connected to a cleaning device 6 for cleaning the safety helmets 10. The inner wall of the cabinet body 1 is connected to a blower device 7 for drying the safety helmets 10. During the cleaning process, the clamping device can rotate with the help of the rotating table to align the part of the safety helmet to be cleaned with the cleaning device for precise cleaning. After cleaning, the helmets are dried by blowing air and then disinfected. After the disinfection is completed, the clamping device rotates the safety helmets by 90° via the rotating table and moves them along the upper slide rail to reduce the distance between the helmets. This allows them to be stacked in a nested manner with convex and concave surfaces, which significantly saves space and doubles the number of safety helmets that can be stored. From cleaning and drying to disinfection, the entire process requires little manual intervention and is basically automated. The cleaning effect is excellent and the operation is convenient.
