Device for simulating rainfall continuously in field

The utility model provides a device for simulating rainfall continuously in the field, particularly relates to a device capable of simulating rainfall stably and continuously by utilizing automatic pressure difference, and belongs to the field of hydrological forecasting in water control projects. The device comprises a water storage tank, a water supply tank, a rainfall adjusting device, a rainfall device and a support; the water storage tank is connected in series with the water supply tank; water is supplied to the water supply tank through pressure difference in the system; and stable rainfall intensity required for an experiment is realized through the adoption of a one-way vent plug and the rainfall adjusting device. The device does not require a power device, is convenient for field experiments, is not required to stop during an experiment, can realize continuous water supply through the water storage tank, is simple and convenient to control the rainfall intensity, and can keep a constant state all th
