A well shut-in device for a precipitation well
This utility model provides a well sealing device for dewatering wells, including a dewatering well pipe and a pull plate device. A positioning component is installed on the inner wall of the dewatering well pipe. A guide hole for the pull plate device is opened in the center of the positioning component, and a guide slope is formed on the inner edge of the positioning component, extending outwards and downwards. The pull plate device is positioned below the positioning component and includes a steel sealing plate, a guide sleeve A, and a rotating component. The guide sleeve A is ellipsoidal in shape, and its bottom surface is fixedly connected to the upper surface of the steel sealing plate. The curved surface of the guide sleeve A fits against the guide slope. A through hole is provided in the middle of the guide sleeve A, forming an installation cavity with the steel sealing plate. The rotating component is installed in the installation cavity and can drive the pull plate device to rotate vertically. This utility model, through the fit between the guide sleeve and the guide slope and the rotating component, can accurately complete well sealing, simplifying the operation steps and adapting to different dewatering well conditions.
