Problems solved by technology

In this way, many inconveniences and potential safety hazards during operation are caused to the laborers.
Dust masks can only ensure the filtration of the workers' breathing air, but cannot effectively protect the dust that falls on the workers' faces
And the breathing resistance is relatively large, so that the laborer has a feeling of shortness of breath. The self-rescue respirator is heavy and the breathing time is short (about 30 minutes).
During the operation and walking process of workers, the wires often collide with the protrusions in the working environment, and the wires often fall off from the slot on the top of the helmet when the workers are operating. The portable power supply and self-rescuer at the waist of the worker When opera

Abstract

The present invention relates to labor safety guard technology, and is especially one multifunctional safety helmet used for dark environment in mine. The multifunctional safety helmet is provided with lighting unit, protecting mask, temperature and humidity regulator, oxygen making unit for self help, gas detector, abnormal stress and pressure detecting alarm, electric leakage protector and other protecting parts. Its power source and wires are set inside the helmet, and its protecting mask is made of soft telescopic material and thus may be folded into the helmet.

Description

technical field [0001] The invention relates to the technical field of labor safety protection, in particular to a labor safety protection and lighting device for underground mine operations. technical background [0002] The underground mine operating environment is dark, dangerous, humid, dusty, and the air quality is poor (high content of combustible and harmful gas components, relatively low oxygen content), and must be equipped with lighting and labor safety protection devices before operation. Existing technology is: separate mining helmets, lighting fixtures, dust masks, and self-rescue respirators are used together. The miners wear helmets, are equipped with dust masks and self-rescuers, and the lighting lamp head is installed on the helmet. The front part is connected with a longer wire between the lamp head and the portable power supply. The wires hang freely from the back of the laborer through the slot on the top of the safety helmet and are connected to the por...
