| description | The utility model relates to a wellhead protection device of a deep-ground sealing well, which comprises a well cover mounted at the upper end of a well body, a sealing box mounted at the upper end of the well cover, a first rotation shaft mounted at the lower end of the sealing box, a second rotation shaft mounted at the lower end of the first rotation shaft, and an arc-shaped gas guide surface fixedly connected to the lower end of the well cover. According to the well mouth protection device of the deep-ground sealing well, the well lid is arranged on the well body to play a role in protection, the fan blades are driven to rotate to enable air pressure at the opening of the well body to be evenly distributed, and therefore the well mouth protection device of the deep-ground sealing well has the advantages that the well lid is arranged on the well body to play a role in protection; and the flexible ribbon outside the second rotation shaft floats along with rotation of the second rotation shaft, and rising ai |
