This invention discloses a porcelain insulator with a snow and ice removal structure and its manufacturing method, relating to the field of insulators. It includes a lower insulating column, an upper insulator, a snow removal assembly, and a central connecting bolt. By setting an upper insulator with a size larger than the lower insulating column's skirt, it can effectively block the lower insulating structure, confining most of the snow accumulation to the surface of the upper insulator. Furthermore, the icicles formed at the edges of the upper insulator are difficult to connect with the snow and ice on the lower insulating column. Through a sliding connecting seat cooperating with the central connecting bolt fixed to the crossarm, the swaying kinetic energy of the transmission line is converted into the up-and-down sliding of the snow removal assembly relative to the upper insulator. This sliding motion drives multiple vibrating plates to periodically squeeze and scrape the surface of the upper insulator, causing the accumulated snow and ice to loosen, break, and slide off. This allows for timely de-icing without additional energy or manual intervention.

The present invention relates to the field of surface water monitoring, and in particular to a sampling device based on surface water monitoring. Technical problem: When the drill teeth come into contact with the shaved ice chips, the ice chips will melt into water, flow down along the icicle, and come into contact with other parts of the icicle, affecting the subsequent detection of water melted from icicles at different depths. Technical solution: A sampling device based on surface water monitoring, comprising a hoisting machine, a frame shell, a hollow cylinder, drill teeth and a power assembly, etc.; the hoisting machine is connected to the frame shell; the frame shell is connected to the power assembly; the power assembly is connected to the hollow cylinder; and the hollow cylinder is provided with a number of drill teeth. Through the cooperation of the first annular push plate and the second annular push plate, the snow water flows through the first channel and the second channel in sequence, and then flows into the first cavity, thereby cooling the drill teeth, and preventing some of the ice chips from quickly melting into water when the drill teeth come into contact with the shaved ice chips, flowing down along the icicle, and coming into contact with other parts of the icicle.
