The invention provides a solar churn drill. The solar churn drill comprises N sets of lens gathering clusters, intelligent control centers, boilers and one-way breakover valves, and a heat insulation tank, a heat insulation buffer tank, a heat supply center, a solar steam turbine, a churn drill body, heat insulation pipes and information connection wires. Each lens gathering cluster is a set of focusing lenses which are perpendicular to solar rays and rotate synchronous to the solar rays; the focuses of the lenses of each lens gathering cluster concentrate in the heat gathering center of the corresponding boiler all the time; when the temperature and the pressure of water in one boiler reach the certain values, the corresponding one-way breakover valve is opened, and overheated water vapor enters the next boiler for further heating; and when the temperature and the pressure of water in one boiler are lowered to certain values along with the output of overheated water vapor, the corresponding one-way breakover valve is closed, the process is carried out in this way repeatedly, overheated water vapor with higher temperature and pressure is produced, and finally, the overheated water vapor with the set temperature and pressure enters the heat insulation tank for storage through the eighth one-way breakover valve. The solar churn drill has the advantages of being efficient and environment-friendly, achieves energy conservation, emission reduction and environmental protection without pollutants, and saves cost.
