Description

Technical Field

[0001] The utility model relates to the technical field of water level measuring devices, in particular to a water level measuring device for reservoir engineering management. Background Art

[0002] The existing water level measuring device detects the water level line by installing the water level detection device on the edge of the reservoir. However, when it is used, when the temperature drops and the water surface freezes, its detection accuracy will be reduced. For example, a Chinese patent discloses a "water level measuring device for reservoir engineering management" with application number "202123046361.4". In this device, the side wall of the shell is penetrated by a compression spring and a fastener through the through groove at the wall, and the length of the fastener is much longer than the length of the through groove. The part exceeding the length is fixed by a fastening bolt, thereby improving the overall stability of the shell and avoiding inaccurate measurement caused by the tilt of the shell. However, when it is used, the shell does not have the effect of heating and heat preservation. When the temperature drops in winter and the water surface freezes, its detection accuracy will be reduced, and its service life may be shortened. Since the components may also be damaged due to expansion and contraction in a low temperature environment, its service life is shortened. Utility Model Content

The heat conducting rod is heated by a heating device to increase the temperature of the heat conducting plate to prevent freezing. In cold winter, the temperature around the water level detection rod is very low, which can easily cause the water inside the protection pipe to freeze, thereby affecting the accurate detection of the water level.

[0025] The internal gas is discharged so that the water level can be raised and lowered smoothly. The protection tube 6 is composed of an anti-corrosion layer 13, a thermal insulation layer 14, and a heat-conducting plate 15. The thermal insulation layer 14 is fixedly connected to the inner surface of the anti-corrosion layer 13, and the heat-conducting plate 15 is fixedly connected to the inner surface of the thermal insulation layer 14.
