Protective garment used for electric welding for leak repairing of oil well pipeline

Abstract

The invention relates to a protective garment used for electric welding for leak repairing of an oil well pipeline. The protective garment is characterized in that a pair of goggles is composed of a dark-color goggle lens and a light-color coated lens, the light-color coated lens is fixed in a face shield, a rotating shaft is arranged at the lower end of the light-color coated lens, the rotating shaft is connected with the dark-color goggle lens, a fire extinguisher connecting pipe and a safety belt are arranged on the asbestos protective garment capable of being worn reversely, a smoke dust filter cartridge is further arranged on the lower portion of the goggles on the electric welding protection face shield, adsorption particles are arranged in the smoke dust filter cartridge, the upper end of the electric welding protection face shield is provided with a head groove, the lower end of the electric welding protection face shield is provided with a lower jaw groove, the two sides of the electric welding protection face shield are respectively provided with an ear protection groove and extend backwards, and a rubber sealing strip is arranged at the edge of the electric welding protection face shield. The protective garment can prevent a constructor from being burnt in the process of electric welding for leak repairing of an oil pipeline; when the protective garment is used, the shield is good in leakproofness, can better block strong ultraviolet light in the welding process, and can effectively prevent poisonous smoke dust from affecting the constructor; besides, the protective garment is simple in structure, convenient to use and low in production cost and using cost.

Description

technical field [0001] The invention relates to the field of protection devices, in particular to a protective clothing for electric welding leakage repair of oil well pipelines. Background technique [0002] In the daily production of the oil field, due to the long-term disrepair of the oil well pipeline or the damage of oil stolen by criminals, perforation often occurs. After the perforation of the oil well pipeline, it is common to use electric welding to repair leaks. However, the oil well pipeline leakage repair welding process is different from the welding of our common tools and components, because the oil well pipeline will generate high temperature during the welding process. Excessive temperature will usually ignite the oil and gas ejected from the perforation of the pipeline, resulting in a large amount of smoke and dust. Toxic gas. The greater the pressure in the pipeline, the fiercer the fire, because the workers are constructing in the pipeline pit manually du...

However, the oil well pipeline leakage repair welding process is different from the welding of our common tools and components, because the oil well pipeline will generate high temperature during the welding process. Excessive temperature will usually ignite the oil and gas ejected from the perforation of the pipeline, resulting in a large amount of smoke and dust. toxic gas

The greater the pressure in the pipeline, the fiercer the fire, because the workers are constructing in the pipeline pit manually dug, the scope is small, the hiding space is limited, they are easy to be burned, and the construction risk is relatively high

At present, we use ordinary welding shields for oil well pipelines to weld leaks. The ordinary shields on the market can only block the strong ultraviolet rays in the welding process, but most of them do not have the function of protecting smoke and toxic gases. The protection against strong light is not thorough enough, which poses a threat to the health and safety of workers engaged in welding
