[0002] As we all know, the wellhead defense device is a protective device for wellhead protection and anti-falling, and it has been widely used in the field of wellhead safety protection; it is found in the use of an existing wellhead defense device that inspection wells are for urban underground The power supply, water supply, drainage, communication, sewage, and gas pipelines of the infrastructure are set up for easy maintenance and installation. During the installation and inspection process, the wellhead is open, and pedestrians will fall into the inspection well if they do not pay attention to the road conditions. Pedestrians on the road cause potential safety hazards, which should be due to the different sizes of wellheads, resulting in low efficiency in finding temporary manhole covers of suitable sizes, resulting in poor adaptability and high use limitations
