Rocker arm upward spraying type rainfall simulator

Abstract

The invention discloses a rocker arm upward spraying type rainfall simulator. The rocker arm upward spraying type rainfall simulator comprises a bracket, a main water supplying pipe and a motor, and is characterized in that a shaft hole is formed in the upper end of the bracket and a cross-shaped rocker arm is arranged; the rocker arm is a cross-shaped water through pipe; the upward direction of the cross-shaped water through pipe is connected with a plurality of adjustable spherical spraying nozzles; the rocker arm is provided with a shaft pipe; the shaft pipe movably penetrates in the shaft hole formed in the upper end of the bracket; a motor is in transmission connection with a crank connecting rod mechanism; and a connecting rod of the crank connecting rod mechanism is hinged with the bottom of one end of the rocker arm. The spraying nozzles upwards spray out water columns in a reciprocating motion process so that wild simulated rainfall is realized. The rainfall device has a simple structure and strong operability and is convenient to move; and compared with similar equipment, for the rocker arm upward spraying type rainfall simulator disclosed by the invention, the energy consumption is greatly reduced and the natural randomness of the rainfall can be represented better.

Description

technical field [0001] The invention relates to a simulation experiment device, in particular to a rocker-arm upward-spraying rainfall simulator capable of simulating rainfall experiments in the field. Background technique [0002] For different purposes of rainfall experiments, researchers have designed a variety of different simulated rainfall devices. The existing field simulated rainfall devices generally include: 1) The high bracket is equipped with side-spray or down-spray rainfall nozzles, and the nozzles are fixed. On the rainfall bracket; 2) Scanning downspray type, the nozzle is driven by the motor and moves on the specified path. In the existing simulated rainfall devices, the nozzles are generally installed on a higher support, and spray downwards to realize simulated rainfall. The bracket is time-consuming and laborious in the process of building and dismantling, and its mobility is poor, which directly affects the test process. In addition, the effective rain...

The bracket is time-consuming and laborious in the process of building and dismantling, and its mobility is poor, which directly affects the test process

In addition, the effective rainfall area covered by existing rainfall simulators is small, and the characteristics of raindrops, such as raindrop particle size and rainfall kinetic energy, are also different from natural rainfall.
