Description

Technical Field

[0001] The utility model relates to the technical field of safety helmets, in particular to a safety helmet wearing detection device at a construction site. Background Art

[0002] Safety helmets are an important piece of equipment for construction workers to protect their personal safety during construction. They are defined as a shallow dome hat made of steel or similar materials worn to protect the top of the head, and a protective device to prevent impact objects from injuring the head. It consists of a helmet shell, a hat lining, a lower cheek strap and a back hoop. The helmet shell is hemispherical, solid, smooth and has a certain degree of elasticity. The impact and puncture kinetic energy of the impact object are mainly borne by the helmet shell. There is a certain space between the helmet shell and the hat lining to buffer and disperse the instantaneous impact force, thereby avoiding or reducing direct damage to the head. Impact performance, puncture resistance, lateral rigidity, electrical insulation and flame retardancy are the basic technical performance requirements for safety helmets.

[0003] When working on a construction site, due to various reasons such as hot weather, construction workers will take off their helmets, which may bring potential safety hazards. However, managers cannot always be on site to watch, which may easily lead to potential safety hazards. Therefore, we proposed a construction site helmet wearing detection device.
