Water level and water flow velocity integral measuring device

Abstract

The invention relates to a water level and water flow velocity integral measuring device and belongs to the technical field of automatic detection. The water level and water flow velocity integral measuring device is characterized in that dual functions of simultaneously measuring the river water level and the water flow velocity are realized, and the measuring device consists of a balance weight block 1, a flow velocity sensor 2, a weighing sensor 3, a steel wire rope 4, a pulley 5, a weighing cable 6, a measuring cable 7, a cable 8, a waterproof junction box 9, a motor 10, a speed reducer 11, a steel wire rope rolling tube 12, a coding sensor 13, a water level intelligent meter 14, a flow velocity intelligent meter 15, a weighing intelligent meter 16, a water level display screen 17, a flow velocity display screen 18 and a weight display screen 19. The water level and water flow velocity integral measuring device has the advantages that the on-line continuous measurement for the river level and the water flow velocity in the fixed place, at the fixed time and in the fixed height is realized, and the water level and water flow velocity integral measuring device is applicable to the fields of water conservancy, hydrology and the like.

Description

technical field [0001] The invention relates to an integrated measurement device for water level and water flow rate, which belongs to the technical field of automatic detection. It is an automatic measurement device with dual functions of measuring water level and water flow rate at the same time, and is mainly used in the fields of water conservancy and hydrology. Background technique [0002] In the technical fields of water conservancy and hydrology, it is necessary to measure the water level and flow of large rivers and rivers. Especially during the flood season, it is necessary to accurately detect the incoming water of each upstream tributary, forecast the arrival time of the flood peak, the highest water level and the maximum flow. Flood control has guiding significance, and the calculation of water flow requires basic parameters such as water level, water flow velocity, river bed cross-section diagram, and flow curve, so accurate measurement of water level and water ...

AI Technical Summary

Problems solved by technology

[0006] The main disadvantages of the water level sensor and flow rate sensor used in patent 200920313547.1 are that they are greatly affected by objective conditions, such as ultrasonic sensors are affected by water fluctuations and wind speed, so they are not suitable for working in environments with strong winds, heavy rains and waves, especially during flash floods the upper reaches of the river; the float water level gauge requires special logging equipment and is not suitable for working in the above harsh environment

[0007] In summary: in the field of water conservancy and hydrology, the current situation is that the measurement of river water level, water velocity and water flow basically still stays in the manual measurement interval, not only the labor intensity of the staff is high, but also the measurement time interval is large. Can no longer meet the requirements of flood control for hydrological forecasting
