Flood discharge atomization rainfall three-dimensional measurement device and method

Abstract

The present invention discloses a flood discharge atomization rainfall three-dimensional measurement device and method. The device comprises a rain gauge, a weather instrument and an installation pedestal, the rain gauge comprises a rain collector, a rain storage cavity, a rain sensor, a power source and control module, a display screen, a rain gauge spirit bubble, a printer and a location system;the installation pedestal comprises a support pier, a clamping head, a supporting leg, an adjusting knob and a pedestal spirit bubble. The flood discharge atomization rainfall three-dimensional measurement device and method collect rainfall at different angles (0-90 degrees) different from the horizontal plane, and the rainfall intensities are subjected to statistics according to different orientations; when the rainfall intensity distribution is measured, the meteorological data such as the wind direction and the wind speed is synchronously measured; a self-recording sensor is employed to obtain a real-time rainfall process; a location system is arranged in the instrument to observe and locate the position information of the rain gauge in real time, the conversion of the measuring pointsdoes not need preset of observation points so as to overcome the defects that the positions of the measuring points cannot be pre-estimated. The system can perform real-time monitoring, recording anddisplay of the observation result, the test items are synchronous, and the automation degree is high.

Description

technical field [0001] The invention belongs to the technical field of hydraulic test and measurement of water conservancy and hydropower projects, and in particular relates to a three-dimensional measurement device and method for atomized rainfall caused by flood discharge of a hydropower station. technical background [0002] Flood discharge atomization refers to the phenomenon of rainfall and fog flow generated in the local area downstream of the hub during the discharge process of the discharge structure of the hydropower project. With the continuous development of dam construction in the world, a large number of high dams and super high dams have been built one after another. These high dam projects have the characteristics of high water head, large flow and narrow canyons. The problem has become more and more prominent, and it has become a new topic that hydropower engineering has paid close attention to in recent years. Research on the forecast method of flood discha...

Problems solved by technology

Therefore, it is difficult to directly use the measuring instruments for observing natural rainfall in conventional hydrometeorology in the measurement of atomized rainfall. Even the existing multi-directional measurement method specially developed for the measurement of flood discharge atomization also shows certain limitations.
