Water gate water level detection device

Abstract

The invention relates to the technical field of hydraulic engineering, in particular to a water gate water level detection device. The water gate water level detection device comprises an elevated stage, a second electric telescopic rod is fixed to the upper surface of the elevated stage, a second output shaft is in slide connection with the upper end of the second electric telescopic rod, and a motor is fixed to the inner side wall of a motor cover which is welded to one end, away from the second electric telescopic rod, of the second output shaft. The motor is in rotational connection with abase through an output shaft. In water gate water level detection, the second output shaft slides to a highest position, then the motor is connected with an external power source, the motor output shaft drives a first electric telescopic rod, a water gauge and the like to rotate centering on the motor, then the first electric telescopic rod retracts or stretches, a water level value of a specified position can be measured, measuring around a certain position and averaging can be realized, and accordingly accuracy in water level detection can be improved.

Description

technical field [0001] The invention belongs to the technical field of water conservancy engineering, and in particular relates to a sluice water level detection device. Background technique [0002] The water level gauge is a device for measuring the water surface elevation at designated locations of rivers, rivers, lakes or other water bodies. It is made of metal or non-metallic materials and marked with scales. The accuracy is generally in centimeters, and the minimum scale is 1cm. Generally, 1 meter is used as a section, and pure red and blue are used as a piece for easy reading. At present, water level gauges on the market can be divided into stainless steel water gauges, stainless steel composite water gauges, polymer water gauges, and aluminum reflective water gauges. [0003] There are following problems in existing technology: [0004] 1. The detection of water level height is the elevation of the free water surface relative to a certain base level. The base level ...

AI Technical Summary

Problems solved by technology

[0004] 1. The detection of water level height is the elevation of the free water surface relative to a certain base level. The base level of a water conservancy lake is a surface with ups and downs. In this way, the location of the water conservancy detection is different, and its base level is not on the same level, so it cannot be compared. Accurately detect the specific height of the water level, but the accuracy is low;

[0005] 2. The water level gauge is soaked in the lake for a long time, and moss and other substances are easy to adhere to its outer wall. These substances cover the scale on the water level gauge, making it difficult for inspectors to observe the above values, and there are certain disadvantages
