Protective structure of precipitation observation well

The utility model relates to the technical field of precipitation observation wells, in particular to a protection structure of a precipitation observation well. A protection structure of a precipitation observation well comprises a protection cover provided with a covering face suitable for covering a wellhead of the observation well; the first fixing piece is arranged on the end face, facing the well mouth, of the covering face and provided with at least two insertion ends suitable for being inserted into the observation well, and the distance between the at least two insertion ends is slightly smaller than the inner diameter of the observation well so that the first fixing piece can be just clamped in the observation well. According to the protection structure of the observation well, the situation that the protection effect cannot be achieved due to displacement of the protection cover is avoided. 本实用新型涉及降水观测井技术领域，具体涉及一种降水观测井的防护结构。一种降水观测井的防护结构，包括：防护盖，具有适于覆盖观测井井口的遮盖面；第一固定件，所述第一固定件设于所述遮盖面朝向所述井口的端面上，具有至少两个适于
