[0002] A boiler is an energy conversion device. The energy input to the boiler includes chemical energy and electrical energy in the fuel. The boiler outputs steam, high-temperature water or organic heat carrier with a certain amount of thermal energy. The original meaning of pot refers to a water container heated on fire, and furnace refers to a place where fuel is burned. The boiler consists of two major parts: the pot and the furnace. The hot water or steam generated in the boiler can directly provide the required thermal energy for industrial production and people's lives, or can be converted into mechanical energy through a steam power device, or the mechanical energy can be converted into electrical energy through a generator. A boiler that provides hot water is called a hot water boiler, which is mainly used for life and also has a small number of applications in industrial production. A boiler that generates steam is called a steam boiler, often referred to as a boiler, and is mostly used in thermal power plants, ships, locomotives and industrial and mining enterprises. A pipe wiping device is required when observing the internal operating status of the boiler.

[0018] 3. The present invention arranges a nylon pad, which is made of nylon and has excellent insulation performance, is non-magnetic, heat-insulating, light in weight, and has high temperature resistance, high strength and corrosion resistance. It can prevent the high temperature in the furnace from damaging the second transparent glass plate and the dark lens, and form a distance between the second transparent glass plate and the dark lens to prevent the second transparent glass plate and the dark lens from being worn. By arranging the dark lens, ultraviolet rays and infrared rays can be blocked. At the same time, the color of the external environment does not change, only the light intensity changes, which prevents the fire from damaging the cornea, lens, and even fundus of the eyes. It can block or absorb part of the light to reduce irritation to the eyes. BRIEF DESCRIPTION OF THE DRAWINGS
