[0002] The existing electronic water gauge is assembled in a splicing way and forms an integral body after installation. The water level of the electrode is measured by the weak conductivity of water to obtain data. The error will not be affected by environmental factors and only depends on the distance between the electrodes. It can automatically detect the water level for a long time and is suitable for water conservancy projects such as rivers, lakes, reservoirs, hydropower stations, irrigation areas and water transfer, as well as water level monitoring in municipal projects such as tap water, urban sewage treatment, and urban road waterlogging. The equipment usually uses stainless steel as a protective shell, which is anti-interference. The interior of the equipment uses highly sealed materials and will not be affected by external environmental factors such as sludge, pollutants, and sediments.

An upper protective cover 103 is arranged on the side of the water gauge 1. A bolt 109 is inserted on the surface of the upper protective cover 103. One end of the bolt 109 is threadedly connected with a nut 110. A mounting foot 107 is arranged on the side of the upper protective cover 103. The mounting foot 107 is penetrated and fixed on the surface of the upper protective cover 103 by the bolt 109. Under the action of the upper protective cover 103, the water gauge 1 will not crack.

The surface of the U-shaped connector 105 is fixedly connected with the extension ruler 101 and the bottom shell 102.

The main controller 3 is fixed in a suitable position through the fixed installation hole 303, so that the water gauge 1 is placed in the water to measure the water depth. When it is necessary to extend the water gauge 1, the extension ruler 101 and the water gauge 1 are extended through the U-shaped connector 105, and the bolt 109 is penetrated through the U-shaped connector 105. The water gauge 1 and the extension ruler 101 are fixed together, and the upper protective cover 103 is fixed to the surface of the water gauge 1 by bolts 109 and nuts 110. When the water gauge 1 needs to be fixed, the mounting feet 107 are fixed to the surface of the water gauge 1 by bolts 109 and nuts 110, so as to facilitate the fixing of the water gauge 1 in the water.
