Problems solved by technology

[0003] Especially for well covers used in gas station oil wells, due to the large volume and mass of the well covers, it is difficult to open the well covers, especially in the case of frequent opening of the well covers, which brings a lot of inconvenience to the use. In addition, the traditional covers are all It is a plate-shaped component with limited strength and is prone to deformation after long-term use. To avoid deformation, the material can only be thickened, which increases the production cost
