Multifunctional hydrological on-line monitoring platform

Abstract

The invention discloses a multifunctional hydrological on-line monitoring platform. The multifunctional hydrological on-line monitoring platform comprises a reinforced concrete platform body arrangedat the middle part of a river channel, the reinforced concrete platform body is formed by a foundation body at the lower part, a stand column body at the upper part, a local bearing platform body which is connected between the foundation body and the stand column body and plays a role in stabilizing, and a stand column platform arranged at the top of the stand column body; the upstream face of thestand column body is a semi-arc face, the downstream side of the stand column body is of a boss body structure arranged along the vertical center line, the width of a boss body is smaller than that of the upstream face of the stand column body, and an isotope online sand meter, a water quality online monitor, an electronic water temperature recorder and an acoustic Doppler flow velocity profilerare arranged on the vertical face of the downstream side of the boss body; and a cantilever stretching towards the center of the river channel is arranged on the stand column platform, and a radar type self-recording water level gauge is arranged on the cantilever. The multifunctional hydrological on-line monitoring platform is high in automation degree, the problems of insufficient low water level observation guarantee rate and floating object impact of a traditional water level observation platform are solved, and therefore automatic online monitoring is achieved.

Description

technical field [0001] The invention relates to a hydrological online monitoring platform, in particular to a multifunctional hydrological online monitoring platform. Background technique [0002] Hydrology is a discipline that studies the temporal and spatial distribution and changing laws of natural water. With the development of the national economy and society, it has gradually formed a comprehensive and reasonable layout including water level, flow, rainfall, water quality, groundwater, evaporation, sediment, etc. Hydrological station network. The hydrological data collected by hydrological instruments and equipment are complete and reliable, and play an important role in hydrological monitoring. According to the investigation on the current application and application scope of hydrological instruments and equipment, hydrological instruments and equipment such as radar self-recording water level gauge, acoustic Doppler current profiler (ADCP), isotope on-line sand meas...

AI Technical Summary

Problems solved by technology

The monitoring platforms of the above-mentioned hydrological instruments and equipment are independent, and have the following shortcomings: 1. Lack of integration and relatively large investment; many hydrological testing facilities in the test section have a certain impact on the safety of flood discharge, and due to the scattered construction of facilities, It increases the difficulty of the operation and maintenance of the management personnel in the later stage, especially for the rivers that are not wide, and the impact of many hydrological tests is particularly obvious

2. The safety and applicability of hydrological instruments and equipment cannot be guaranteed

Such as the radar water level observation platform, ADCP platform, and water temperature observation platform in the river channel, because most of them adopt the form of steel structure, they are very vulnerable to the impact of floating objects and the entanglement of aquatic plants during medium and high floods. Affected by siltation, the operation and maintenance work of station personnel has been greatly increased

3. The guarantee rate of low water monitoring on the radar water level observation platform is insufficient, and the safety of high water monitoring cannot be guaranteed; for the radar water level observation platform set up on the bank of the river, if there is swing or silting in the river, it will not be guaranteed to be able to monitor Low water level; for the radar-type water level observation platform installed in the river, it is very vulnerable to the impact of floating objects during medium and high floods, and the safety cannot be guaranteed
