Problems solved by technology
During the fixing process, it is difficult to avoid the installation base of the water gauge and the water gauge to remain vertical when the firm requirements are met, which will increase the error of the water gauge observation
In addition, under the conditions of rapids and torrents, it is difficult to have a good working surface that can fully guarantee the engineering standards of water gauge fixing

A circuit control assembly is arranged in the floating ruler; a water wheel motor and a measuring cylinder are arranged on the floating ruler; a floating plate is arranged in the measuring cylinder; the measuring cylinder and the floating plate are respectively provided with a fixed gate sensor II and a movable gate sensor II; the floating ruler is installed on a floating plate support; the floating plate support is installed on a fixed installation module through a supporting beam; the fixed installation module is supported by a supporting pile I and a supporting pile II which are coaxially installed; and the movable gate sensor I and the fixed gate sensor I are installed on the supporting pile I and the supporting pile II respectively. The device is simple in structure, and artificial energy supply is not needed; multiple functions of automatically correcting the posture and observing the water level and the flow speed are achieved after installation, and water level variable-frequency measurement can be achieved according to changes of the water flow speed; and double-precision measurement is achieved, and a basis is provided for data correction and multi-party application.
Description
technical field [0001] The invention belongs to the technical field of hydrological measurement, and in particular relates to a double-precision frequency-variable water level gauge based on hydraulic automatic posture correction. Background technique [0002] Water level monitoring of river basins is one of the important tasks of hydrological data measurement and calculation. Water level data is closely related to human social life and production, and is an important basis for water conservancy project planning, design, construction and management. Its detection accuracy and frequency are particularly important for flood control and drought relief. [0003] It is generally measured with a water level gauge and a water level gauge. The observation time and observation frequency vary with the hydrological forecast and hydrological information requirements. Generally, the daily measurement is 1-2 times. During the rainy season and flood period, the observation frequency is in...
