Instantaneous water distribution measuring device

The invention discloses an instantaneous water distribution measuring device which comprises a platform (1) connected with a plurality of water containing boxes (101), and is characterized in that the platform (1) is connected with a deflecting mechanism; the water containing box (101) is connected with a lifting mechanism and a starting mechanism; the deflecting mechanism is used for adjusting the gradient of the platform (1) so as to simulate the gradient of the terrain; the lifting mechanism is used for adjusting the height from the water containing box (101) to the platform (1); different height distribution of the water containing boxes (101) on the platform (1) is adjusted to simulate a flat ground, a mountain, a building group or a tree group; the starting mechanism is used for starting the water containing box (101) to conduct instantaneous water collection so as to measure instantaneous water quantity distribution. The problem that the measurement result is distorted due to the fact that the field en
