An assembled rainfall-adjustable simulated rainfall increase and decrease device

Abstract

The present invention provides an assembled device for simulating rainfall increase and decrease with adjustable rainfall, comprising a main frame and an interception and distribution device. The main frame is divided into a rainfall increase zone and a rainfall decrease zone. The throttling and distribution device comprises an upper frame, a water trough, an angle adjustment mechanism, and an opening adjustment mechanism. The upper frame is hinged to the main frame via a hinge. The water trough is mounted on the upper frame and is provided with a plurality of water troughs. The water troughs include two V-shaped rain shields that are hinged to each other. The bottom of the rain shields in the redistribution section of the water trough has a leakage groove. The angle adjustment mechanism is used to drive the upper frame to rotate relative to the main frame, and the opening adjustment mechanism is used to drive the hinged rain shields to rotate. The device can adjust the angle of the water trough to reduce water transport loss, and can also adjust the angle between the two rain shields in the water trough to control the increase and decrease of rainfall. The entire device has a simple structure, low cost, and simple operation, making it suitable for promotion.
