Water level measuring device for reservoir project management

Abstract

The invention discloses a water level measuring device for reservoir engineering management, which comprises a measuring main body, and a floating device is arranged at the bottom of the measuring main body; through cooperation of the measuring body, the floating device, the strain device, the contact device and the take-up device, the water level measuring device can directly measure the water level in a still water and windless environment, meanwhile, a to-be-corrected water level value can be measured in a flowing water and windy environment, and through cooperation of the floating device and the limiting device, the water level measuring device can be adjusted by people according to the use environment so as to properly amplify the influence of wind power and water flow, the overturning angle of the strain device is monitored through cooperation of the dip angle measuring device and the conduction device, and the water level measuring device can correct the water level value to be corrected according to the overturning angle of the strain device, therefore, the accurate reservoir water level value is obtained, the detection accuracy is high, the actual condition of the reservoir water level can be truly reflected, and the practicability of the water level measuring device for reservoir project management is improved.

Description

technical field [0001] The invention relates to the field of water level measuring devices, in particular to a water level measuring device for reservoir engineering management. Background technique [0002] Reservoirs are water conservancy engineering buildings for flood storage and water regulation. It refers to artificial lakes formed by building barrages at the narrow mouths of ravines or rivers. Sometimes natural lakes are also called reservoirs. The scale of reservoirs is usually divided into small, medium, and large according to the storage capacity. Reservoir engineering planning is a water conservancy engineering planning that takes the reservoir as the research object. It generally consists of water retaining, flood discharge, These buildings have different functions and cooperate with each other to form a water conservancy hub during operation. Reservoir engineering planning should usually be carried out on the basis of river basin planning, regional water conserv...

AI Technical Summary

Problems solved by technology

[0003] The existing water level measuring device for reservoir engineering management is mainly composed of machine base, float, balancer, chain, water level wheel, photoelectric code sensor, etc. When in use, the water level rises first, then the float floats up, and then the balancer sinks and pulls the chain , then the chain rotates with the water level wheel, and then the photoelectric encoder sensor senses the rotation of the water level wheel and converts it into a value, which is used to measure the change of the water level. However, a part of the float is exposed above the water surface, which will make the float It is easy to pull the chain under the action of wind, and then make the water level wheel rotate, resulting in an increase in the error of the water level detection result. Zipper chain, which will also cause the chain to move, which will cause the water level wheel to rotate, which will further increase the detection error, resulting in the measured water level data not being enough to accurately reflect the real water level of the reservoir. Therefore, it is urgent to design a water level for reservoir engineering management. measuring device
