[0002] Oil and gas wells are usually equipped with well pits at the wellheads, which facilitate the maintenance and inspection of wellhead equipment. However, both terrestrial gas wells and marine gas wells currently use open wellhead well pits, which causes rainwater to accumulate in the wellhead well pits and even cause the wellhead to be flooded during the rainy season, resulting in damage to the wellhead equipment. Utility Model Content

When it is not necessary to shield the oil and gas wellhead pool, the projection size of the shielding part can be reduced to facilitate the continued operation of the oil and gas wellhead equipment. The shielding part is in a fully expanded state, which means that the projection size of the shielding part is adjusted to the maximum state by moving the shielding part relative to the mounting part.
