Wall structure for energy-saving and environment-friendly building

The utility model relates to the technical field of buildings, and discloses an energy-saving and environment-friendly building wall structure which comprises a building wall body, and a first keel is arranged on the outer side of the building wall body. According to the wall structure for the energy-saving and environment-friendly building, the first linear module drives the first rotating module and the convex lens on the second keel to be close to or far away from the heat exchange plate on the first keel, so that the focusing intensity of the convex lens and the heat exchange plate to solar energy is preliminarily adjusted; the first rotating module drives the convex lens to rotate relative to the second keel, so that the focusing intensity of the convex lens and the heat exchange plate on solar energy and the conversion rate of converting the solar energy into heat energy are further adjusted; according to the wall structure for the building, the conversion rate of converting solar energy into heat energ
