[Scope of Claim for Utility Model Registration] (1) In a water level observation well, a hollow pointed cylindrical antifreeze float container that floats separately from a float for detecting water level, and an electric heater housed in the container. and a waterproof cable that is connected to the electric heater and suspended in water in order to supply power to the electric heater, so that the heat generated by the electric heater can be used without interfering with water level detection by the water level detection float or the like. A freeze prevention float for a water level observation well, characterized in that the water surface is prevented from freezing. (2) In paragraph 1 of the claims for utility model registration,
The float container is equipped with an air permeable sintered metal on the pointed end to prevent water from entering when landing on water, and the float container made of a pointed cylindrical body can be easily moved when a counterweight comes into contact with the drop. Freezing prevention float for water level observation well.
