Description
Technical Field
[0001] This utility model relates to the field of welding technology in industries such as industrial manufacturing, energy, construction and infrastructure, and specifically to a reverse-folding umbrella-shaped welding device. Background Technology
[0002] In fields such as power operation and maintenance, building electrical systems, and industrial equipment commissioning, electric arcs and sparks are often generated during electrical work. As a core safety protection tool for electrical work, the arc-catching device must effectively collect electric arcs and sparks and isolate them from contact with external flammable materials and equipment.
[0003] During the welding process of the aforementioned reverse-folding umbrella-shaped fire-receiving device, the welding slag that falls onto the fire-receiving umbrella surface may come into contact with the umbrella ribs. Because the welding slag is at a high temperature, it is very easy for it to stick to the umbrella ribs. At best, this will cause the surface of the umbrella ribs to become uneven, and at worst, it will damage the connection and prevent it from opening and closing. In addition, since it is designed to open and close in the forward direction with the umbrella ribs facing upward, it is difficult to remove welding slag and other impurities. As a result, the device is not very effective in use and needs to be improved. Utility Model Content
